Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home control system that uses a power line as a control and transmission line for response signals to remotely and centrally control a plurality of electronic devices in a home.

[0002]

Remote control of a plurality of electronic devices at home,
In a centralized control home control system, a method is widely known in which a power line that has already been wired at home is used as a control and response signal transmission path. This is to avoid waste such as dedicated wiring work and use of dedicated communication lines.

For controlling and responding to these devices, the HBS protocol defined by the Home Bus System (HBS) of the Japan Electronic Machinery Manufacturers Association Standard ET-2101 has been proposed, and each command is included in the command. It includes a single-function control and response command for controlling and responding to the device address, specification of the function to be controlled, and timer setting time. FIG. 10 shows a basic format of the control signal of the HBS command, PR is a priority code for performing contention control of simultaneous message transmission, SA is a self address,
DA is a partner address, CC is a control code for identifying a protocol switch or a data field, BC is a message length code that specifies the number of characters in the data field, D
ATA is data, operation code, operand, etc. described later, FCC is a check code for detecting a frame transmission error, DMY is a dummy allocated for error check calculation time, and ACK / NAK is a response code of the receiving terminal. HD, which is the content of DATA, is a header code indicating the presence or absence of a command identification and address,
SA 'is a self sub-address, DA' is a partner sub-address, SSDA is a self-sub-device address, DSDA is a partner sub-device address, TS is a table selector which is a code of a table for specifying the operation of the device, and OPC selects a control function. Operation code, OPR
Is an operand that is a function control code, and TC is a termination code that indicates the end of one command when a plurality of types of commands are continued. Each code and address in the frame has a total of 11 bits including a start bit (1 bit), data (8 bits), parity (1 bit), and stop bit (1 bit). Also, D
A plurality of types of codes and addresses in ATA can be treated as one command.

Conventionally, as control and response signals for equipment,
A command in which these single control and response commands are arranged in series is subjected to modulation such as frequency modulation or spread spectrum modulation, and output on the power line which is the transmission path. For example, the command 1 "Turn on the power of a certain device"
If the above HBS command is used for the second transmission, FIG.
As described above, there are 14 types of codes and addresses, and a total of 154 bit commands are provided. The command in the lower part of FIG. 11 is a hexadecimal number, and the address is optional from 00 to FF depending on its setting. In addition, since the device is designated by the address and the FCC is the value of the two's complement of the sum from SA to OPR, it is set to ** here. Then, the receiving device receives this command and
ACK / NAK to the sender after making an error determination in MY time
Will be returned.

[0005]

However, in general,
Since the signal transmission characteristic of the power line is poor, it is common to set the ratio of signals to be transmitted (transmission rate) low in the home control system. Moreover, the device control and response commands as described above must be compatible with many functions of many devices,
As a result, the command becomes long as shown in FIG. As a result, the probability of occurrence of transmission / reception errors such as incomplete transmission of commands increases on a transmission line with poor transmission characteristics such as a power line. Further, since the command is long, there is a problem that the signal amount (traffic) of the transmission line is increased in combination with the low transmission rate on the power line, and the reliability of data transmission is further reduced.

In view of the above, it is an object of the present invention to provide a home control system capable of reducing a traffic on a power line by assigning a simplified command to a frequently used command.

[0007]

As shown in FIG. 1, a main control device 2 for centrally controlling a plurality of devices 1 and a plurality of sub-devices for controlling each device 1 are provided. A control device 3 is provided to perform data transmission between the main control device 2 and the sub control device 3 by using the power line 4.
A command allocating means 21 for allocating a simplified command to a frequently used command among commands transmitted to each other via the power line 4, and an allocation notification for informing that the simplified command is allocated to the sub-control device 3. Means 22
Is used to control and respond to the device by using a simplified command. Then, the command assigning means 21 is configured to detect whether or not the command to be transmitted has been used a predetermined number of times or more and to assign the simplified command when the command has reached the predetermined number of times or more.

As shown in FIG. 6, the problem solving means according to claim 3 informs the user that the simplified command has been assigned, and each device 1 by using the simplified command input from the outside by the user. And means 31 for controlling and responding to.

The problem solving means according to claim 4 is provided with a means for the user to set a simplified command.

According to a fifth aspect of the present invention, there is provided means for detecting the use status of a simplified command and changing the allocation so that the simplified commands are arranged in order of frequency of use.

[0011]

In the problem solving means according to claims 1 and 2, when the drive control of each device 1 is performed, the command for device control is transmitted from the main controller 2 to the power line 4. At this time, the main control device 2 always detects a passing control command and a response command from the device side, and when it detects that the number of times of use of a certain command reaches a predetermined number or more, A short command is assigned.

When the assignment of the simplified command is completed, the main control device 2 notifies the assigned simplified command to the sub control devices 3 of all the devices 1 on the power line 4, and each of the sub control devices that have received the notification. In 3, the simplified command is stored. After that, the device control and response are executed by the simplified command, so that the traffic on the power line 4 is reduced.

In the problem solving means according to the third aspect, when the main control unit 2 assigns a simplified command to a command that is frequently used, the user is informed of the content thereof. Then, the user finds that the frequently used command is simplified, and if the memorized simple command is memorized, the user can externally control the device.

In the problem solving means according to claim 4, when the user sets a simplified command in advance for a command to be simplified, if there is already a simplified command automatically assigned, the user sets. Is given priority and a simplified command is assigned according to the user's setting. Therefore, the user can set a command that the user can easily remember, rather than a command pressed from the device.

In the problem solving means according to claim 5, the main controller 2 detects the usage frequency or usage status of the simplified command already assigned,
If the simple commands are not in the order of frequency of use,
Main controller 2 rearranges them in order. Therefore, it is possible to deal with a change in the usage status of the device 1 by the user.

【Example】

(First Embodiment) The home control system of the present embodiment centrally controls a plurality of electronic devices (lighting, air-conditioning, security devices, etc.) in a home.
, A main controller 2 for centrally controlling a plurality of devices 1,
The main control device 2 is provided with a plurality of sub-control devices 3 for controlling each device 1 and using the existing power line 4 installed in the home.
Data is transmitted between each sub control unit 3.

The main controller 2 has a command transmitter / receiver 5 for transmitting and receiving control commands for each device 1 and a response command from the device side, and a CP as a central processing unit.
U6, ROM 7 in which control and response commands of the device 1 are stored, RAM 8 in which control and response commands of the device 1 are stored, and amplitude, frequency, phase, spread spectrum modulation, etc. for transmitting and receiving signals. Modulate in the desired way,
A modulator / demodulator 9 that performs demodulation, and a user executes equipment control,
And a home information board 10 capable of intensively checking the status of each device. The main controller 2 is connected to the power line 4 via the modulator / demodulator 9. Also,
The home information panel 10 is provided with buttons for controlling devices, switches and the like, LED display for status confirmation, liquid crystal display with numbers and pictograms, speakers with voice, etc. The equipment can be controlled and managed.

On the other hand, the sub control unit 3 includes a command transmitter / receiver 11 for transmitting and receiving control commands from the main control unit 2 and response commands to the main control unit 2, a CPU 12 as a central processing unit, and a device 1. A ROM 13 in which control and response commands and the like are stored, a RAM 14 in which control and response commands and the like of the device 1 are stored, and a desired method such as amplitude, frequency, phase, and spread spectrum modulation for transmitting and receiving signals, It is composed of a modulator / demodulator 15 that performs demodulation. Then, the sub-control device 3 is the modulator / demodulator 1
5 is connected to the power line 4 via the command transmitter / receiver 11
Each device 1 is connected to. It should be noted that the CPU 12 of the sub control device 3 has a function of determining a command transmitted from the main control device 2 via the power line 4 and a simplified command when the command is determined to be a simplified command described later. Is converted into an original command to control the device 1. Further, the sub-control device 3 can also perform data transmission between each device.

The CPU 6 of the main controller 2 detects the frequency of use of control and response commands, etc., and simplifies the frequently used commands among the commands mutually transmitted via the power line 4. A command allocating means 21 for allocating a simplified command and an allocation notifying means 22 for informing that the simplified command has been allocated to the sub-control unit 3 are provided, and the simplified command is used to control the device 1 and respond. .

The command assigning means 21 is configured to detect whether or not the command to be transmitted has been used a predetermined number of times (the number of times per unit time) or more, and to assign the simplified command when the number of times has reached the predetermined number or more. There is. Further, when there are a plurality of commands that have reached the predetermined number of times or more, the simplified commands are assigned in descending order of frequency of use.

When the simplified command is assigned, the allocation notifying means 22 transmits the content of the simplified command to each sub-control device 3 via the power line 4, and each sub-control device 3 stores the content in the RAM 14 when it receives the content. Keep it.

The simplified command, as shown in FIG.
It consists of a command section and an end code section,
The header part is for distinguishing a general command from a simplified command. The command part indicates the original command. The simplest command among the commands that can be allocated is allocated, and when there are a plurality of frequently used commands, the command part is in the order of 1, 2, 3. Assigned. The end code part indicates the end of the simplified command. For example, the conventional H shown in FIG.
A general command such as a BS command is the C command of the main controller 2.
Converted by the PU 6 as shown in FIG. 2, the simplified command is changed to the original command, and each device 1 is transferred via the power line 4.
Be transmitted to.

In the above structure, the CPU of the main controller 2
The operation of assigning the simplified command by 6 will be described with reference to the flowchart of FIG. When the user operates the home information panel 10 to control the drive of each device 1, the control command passes from the command transmitter / receiver 5 of the main controller 2 through the CPU 6, and is modulated by the modulator / demodulator 9 to obtain the power line. 4 is transmitted. At this time, the CPU 6 of the main control device 2 always detects the passing control command, the response command from the device side, and the like, and the usage status and the usage frequency are R
When the control command is stored in the AM 8 and is not frequently used and is not simplified, the control command is sent as it is from the modulator / demodulator 9 to the sub control device 3 of the device 1 to be controlled via the power line 4.

Then, when it is detected that the number of times the non-simplified control command has been used has reached a predetermined number of times per unit time or more, the CPU 6 enters the simplified command allocation routine to start the allocation operation for the control command. Here, if the control command is an HBS command under the control of, for example, "crime prevention set," the configuration is as shown in FIG. In this case, the FCC detects the transmission error of the frame, and the SA indicates the end of the data field (here, O
The value of the two's complement of the sum up to the character of (PR) is assigned, and a very long command transmission of 110 bits is required, and when the device control content increases or the number of devices increases,
It will be a longer command transmission. Further, even in the conventional simple control of "turning on the power of the device" in FIG. 11, a 154 bit command is required, which causes a command transmission / reception error, so that the command is simplified. Be seen.

First, 1 is assigned to the command part of the simplified command shown in FIG. 2, and it is confirmed whether the command has already been assigned. If it has already been assigned, 1 is further added to the command part to proceed with the confirmation. And if the command is not assigned to the command section,
The allocation of the command section is confirmed. Then, when the allocation of the command portion of the simplified command is completed, the main control device 2 stores the allocated command portion of the simplified command in its own RAM 8 and informs the sub-control devices 3 of all the devices 1 on the power line 4. However, in each of the sub control devices 3 that have received the notification, the command portion of the simplified command is stored in the RAM 1
4 is stored. In each sub-control device 3, data transmission between each device is also performed by using a simple command.

After that, the simplified command is transmitted to the power line 4 with the header portion and the end code portion attached to the confirmed command portion, and then to the sub-control device 3 of the device 1 to be controlled. Here, as a method of determining the header part, a command which is not used in PR which is the head part of a general command (here, the HBS command in FIG. 4) is used. If there is no command that is not used in the head part, consider the next SA part, and increase the number of commands in order, and the commands that are not assigned by general commands or remain as spare parts are the shortest. The command is used as the header of the simplified command. Also, the end code part is arbitrarily determined. The simplified command assigned in this way is simplified into a 29-bit command as shown in FIG.

Then, the simplified command sent to the sub control unit 3 via the power line 4 is received by the CPU 12 via the modulator / demodulator 15, and the CPU 12 determines whether or not the command is a simplified command. Be seen. At this time,
The CPU 12 determines the difference between the general command and the simplified command in the header portion, and if the command is a general command, the command is passed as it is, and the command transmitter / receiver 11 transmits the command to the device 1, Device control according to the content is executed. On the other hand, if the command is a simplified command, the information stored in the RAM 14 is inversely converted into the original general command. Then, the general command converted from the simplified command is sent to the command transmitter / receiver 11 to execute the device control.

If a simplified command has already been assigned to the control command passing through the CPU 6 of the main control unit 2, the command portion of the assigned simplified command is called from the RAM 8 and the header portion and the end are added to the command portion. It is transmitted to the device 1 to be controlled with a code part.

Actually, depending on the situation of each family,
In many cases, there are a plurality of commands that are frequently used, and it is considered that there are many crime prevention alert sets for security-related commands such as on / off and setting of the device 1 such as an air conditioner. Then, FIG. 5 shows a simplified version of a plurality of commands in order. First of all, "Power on / off of air conditioner" is the most common.
become that way. Here, the air conditioner is specified by the partner address information of DA, DA ', and DSDA, but since it is arbitrary by each system, the address is set to **. Also,
The self-address information of SA, SA ', and SSDA is also optional depending on each system, so it is designated as **. Next, there are many cases where "the temperature of the air conditioner is lowered by 1 ° C". If this is described by the HBS command, it becomes as shown in Fig. 5 (b). In this case, the address handling is the same as in FIG. And it becomes "crime warning set", and if you describe this with HBS command,
It becomes like FIG.5 (c). In this case, the handling of the address is the same as in FIG. 5A, the data (0C) of the partner address DA is for NT (Network Termination) standardized by HBS, and the function of NT is telephone line monitoring, It has control and status notification functions.

Then, when these commands are simplified by the command assigning means 21, first, "power on / off of air conditioner" is as shown in FIG. 5 (d). This header part may be arbitrary as long as it is a spare part of the PR of the HBS command, but here, as an example, C7 (1100011: binary number)
And In the PR of the HBS command, the area of binary number (** 000 **) is the spare area. Although the end code part is optional, EC is used here as an example. Below, "Reduce the temperature of the air conditioner by 1 ° C" is shown in Fig. 5 (e), and "Crime prevention alert set" is shown in Fig. 5
In (f), in the command section in descending order of frequency of use,
1, 2, and 3 are sequentially assigned.

As described above, since the simplified command is assigned to the frequently used command by the main control unit 2, the 110-bit command shown in FIG.
It becomes 9 bits, and the 154 bit command in FIG. 11 becomes 2
It is 9 bits. Therefore, since data transmission is performed using a simplified command having a small number of bits, about 74% of the traffic of the command of FIG. 4 and about 81% of the traffic of the command of FIG. If the simplification is further promoted, traffic can be reduced by 74% or more in the entire system, the probability of occurrence of transmission / reception error is reduced, and the reliability of the system is improved.

Moreover, since the simple control command is automatically assigned by the main control unit 2 and the sub control unit 3 is notified, the simple control command can be used in the system and the data between the respective devices can be used. Transmission reliability is also improved.

Furthermore, since the simplification of this command is performed by the front end of the system, that is, the main control unit 2, it can be applied to any existing home control system.

In the above embodiment, the single command to be simplified has been described. However, if the command for controlling a plurality of devices at a time can be simplified, a further traffic load will be increased. It is possible to decrease.
In other words, if the 110-bit command as shown in FIG. 4 is simplified, the number of bits is reduced by about 85%, so that the traffic on the power line 4 can be reduced. By simplifying a plurality of commands such as turning on the air conditioner to release the security alert and start heating the bath, it is expected that the traffic on the power line 4 will be reduced by about 87%.

(Second Embodiment) In the home control system of the present embodiment, as shown in FIG. 6, the home information panel 10 is used to notify the user that the simplified command has been assigned to the main control unit 2. Alternatively, the modem 3 as a means for controlling each device 1 by using a function of notifying by characters or the like and a simplified command input from the outside by the user
1 is provided. The modem 31 is connected to the home information panel 10 and the CPU 6 of the main control device 2 and is connected to the outside through a telephone line, and the user uses a public telephone or the like to externally connect each device 1 in the home. It can be controlled. The other structure is the same as that of the first embodiment.

In the above structure, the CPU of the main controller 2
When a simplified command is assigned to a frequently used command by the CPU 6, the content is sent from the CPU 6 to the home information board 10 and the user is informed by characters, voice, etc. by a liquid crystal display of the home information board 10 or a speaker. .
Then, the user finds that the frequently used command is simplified, and remembers the simplified command. Then, the user can control the device from the home information board 10 using the simplified command. Further, when the user wants to operate the device 1 in the home from the outside, the simplified command is received by the CPU 6 via the telephone line and the modem 31 by transmitting the simplified command from the public telephone through the telephone line. Then, the CPU 6 operates to send a simplified command to the sub control device 3 via the power line 4 to control each device 1.

In this way, since the assigned simplified command is notified to the user, the user can also use the simplified command and can easily control the device 1 from the outside. Moreover, even when trying to operate the device 1 from the public telephone line outside the home via the modem 31, it is not necessary to remember many numbers such as controlled device numbers and operation control numbers as in the conventional case, and a simple command can be issued. It only needs to be remembered, so it does not burden the user.

(Third Embodiment) In the home control system of the present embodiment, the CPU 6 of the main control unit 2 is provided with a function of allowing the user to previously set simple commands for frequently used commands. There is. This is because the user can set a simplified command for a command that the user wants to simplify by operating a switch or a key provided on the home information panel 10. The user can use the set simplified command. Subsequent device control can be performed. In addition,
The other structure is the same as that of the first embodiment.

The operation when the user allocates the simplified command will be described with reference to the flowchart of FIG.
First, the user operates a switch or key of the home information panel 10 to set a simplified command for a command to be simplified. Then, the CPU 6 of the main controller 2
Then, it is detected whether or not the simplified command to be assigned by the user has already been used. Then, if it is not used, the CPU 6 enters a simplified command allocation routine and allocates the command set by the user.

On the other hand, if the simplified command to be assigned by the user has already been used, it is determined whether the simplified command is set by the user or automatically assigned by the CPU 6. If it is assigned by the CPU 6, the simplified command assigned by the CPU 6 is reassigned and changed by the assignment routine. Then, the user's setting is prioritized, and the simplified command is assigned according to the user's setting. If the user has previously set, the user is informed that the setting has already been made using the liquid crystal display of the home information panel 10, the speaker, etc., and prompts the user to change the command to be set.

When the allocation of the simplified command is completed, the contents are notified to the sub-control unit 3 of each device 1 and stored in the RAM 14, and the subsequent data transmission is performed by the simplified command.

As described above, since a simplified command can be set for a command that the user wants to use regardless of whether the system is being used or is being used, it is not frequently used in the system but is often used by the user. About the command,
It is possible to assign a simple command of your choice. Therefore, the traffic of the power line 4 can be reduced by the user's simple command setting, and the user can set the number easy to remember as a command instead of the command pressed from the device, and the simple command set by the user can be set. Since the priority is assigned, the system is easy to use and the operability of the system is improved.

(Fourth Embodiment) In the home control system of the present embodiment, the CPU 6 of the main control unit 2 detects the usage status of the simplified commands and changes the allocation so that the simplified commands are arranged in the order of frequency of use. Functions are provided. The rest of the configuration is the same as in the third embodiment.

This is to change the assignment of the simplified command according to the change in the usage status of the user's device 1, and the changing operation will be described below with reference to the flowchart of FIG. First, the CPU 6 of the main control unit 2 detects a general command, detects the frequency of use or the usage status of the already assigned simplified command, and stores the information in the RAM 8. Then, the information is read from the RAM 8 at regular time intervals, the usage frequency of the simple commands is calculated, and it is confirmed whether the short simple commands are assigned in descending order of usage frequency.

If the simplified commands are not in the order of frequency of use, the CPU 6 of the main control unit 2 rearranges them in order, and the changes are made, and the changed contents are sub-items of each device 1. The control device 3 is notified and the content is stored in the RAM 14 of the sub-control device 3. Then, thereafter, data transmission is performed by the simplified command, and the assignment of the simplified command is changed at regular time intervals.

As described above, even after the simple command is set, similarly to the general command, the usage frequency and the usage status of the simple command are continuously detected, and the simple commands are rearranged in the order of high usage frequency, that is, in the order of small number of bits. So
It is possible to constantly reduce the traffic on the power line 4 according to the change in the usage frequency of the simple commands. Moreover, since the assignment of simplified commands is changed at regular intervals, it is possible to quickly respond to changes in the usage status of the home control system due to the passage of time or changes in the living conditions of the user.

By the way, the assignment of the simplified commands according to the above-described embodiment is intended for all the simplified commands, but in this case, the simplified command set by the user is also changed, so the user is changed. This is very troublesome for the user because it is necessary to re-remember things. Therefore, in the CPU 6 of the main controller 2,
A function is provided to exclude the simple commands set by the user from the target when changing the allocation of the simple commands.
This function will be described below based on the flowchart of FIG. In other words, when it becomes necessary to change the assignment of simple commands, it is confirmed whether or not there are some simple commands set by the user. Short short commands are sorted in descending order. Then, if there is a simplified command set by the user, the assignment is changed to the remaining simplified commands excluding it. At this time, since the order of the items set by the user is fixed, they can be rearranged in any other vacant order. In this way, since the simplified command set by the user is excluded from the assignment change, the simplified command set by the user can be used as it is, and the user can save the trouble of newly remembering the command.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention. For example, in the above embodiment, the simplified command is assigned by the CPU 6 of the main control device 2, but the CPU of the sub control device 3 is assigned.
It may be performed by the CPU 12 or by the CPUs 6 and 12 of both the main controller 2 and the sub controller 3.

In the above embodiment, the control command is described as a simplified command, but the response command is also simplified.

Further, the main controller 2 and the sub controller 3
Memory is RAM8,14 and ROM7,13 2
Although the types are used, each memory may be internally assigned to each area. Furthermore, each CPU 6,1
2, RAM8,14 and ROM7,13 may be shared with that of the command transceiver.

The RAMs 8 and 14 and the ROM 7,
If 13 is a non-volatile memory such as a flash EEPROM, even if the power is completely cut off due to a power failure or the like and the system is no longer supplied with power, the flash EEPROM can display the contents of assignment of simple commands, general commands, and usage status of simple commands. Since it is stored, it is not necessary to assign a simplified command after the power is restored, and a command with reduced traffic on the power line suitable for each home can be used promptly.

[0052]

As is apparent from the above description, according to claims 1 and 2 of the present invention, since a simplified command is assigned to a command which is frequently used by the main control device, the number of bits has conventionally been large. The command has a small number of bits. Therefore, since data transmission is performed using a simplified command having a small number of bits, it is possible to sufficiently reduce traffic on the power line on which the command is transmitted, and the probability of occurrence of transmission / reception error also decreases.
The reliability of the system is improved.

Moreover, since the simple control command is automatically assigned by the main control unit and the fact that it has been assigned to each sub control unit is notified, the simple control commands can be mutually used in the system, and data between respective devices can be used. Transmission reliability is also improved.

Further, since there is no limitation on the device control and response command to be detected, it is possible to support all the commands for the conventional home control system.

According to the third aspect, since the assigned simplified command is notified to the user, the user can use the simplified command, the device can be easily controlled from the outside, and the device can be operated from the outside. Also, unlike the conventional case, it is not necessary to memorize many numbers such as controlled device numbers and operation control numbers, and since it is sufficient to memorize simple commands, the user is not burdened.

According to the fourth aspect, the simplified command can be set for the command desired to be used in advance regardless of whether the system is being used or is being used. Therefore, the user can assign the desired simplified command. Therefore, it is possible to reduce the power line traffic by the user's simple command setting, and the user can set the number easy to remember as a command instead of the command pressed from the device, which facilitates the use of the system. Operability is improved.

According to the fifth aspect of the present invention, even after the simple command is set, similarly to a general command, the usage frequency and usage status of the simple command are continuously detected, and the simple commands are arranged in descending order of frequency of use, that is, in ascending order of number of bits. By rearranging, the traffic on the power line can be constantly reduced according to the change in the usage frequency of the simplified commands. Therefore, it is possible to quickly respond to changes in the usage status of the home control system due to the passage of time or changes in the living status of the user.
