Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

Usually, the frequency of the signal we generally need to send is low frequency. If it is transmitted according to the frequency of its own data, it is not conducive to reception and synchronization. Then, in the process of wireless communication, in order to facilitate the long-distance transmission of some low-frequency signals (such as voice signals spoken by a user), the electronic device will use a carrier wave to transmit the content to be expressed by the low-frequency signal. Specifically, the electronic device will move the spectrum of the low-frequency signal based on the modulation technology. During the modulation process, the electronic device will use the content to be expressed by the low-frequency signal to modulate the high-frequency carrier signal, so as to use the high-frequency carrier to convert the content of the low-frequency signal. For long-distance transmission, after receiving the high-frequency carrier signal, the receiver demodulates the low-frequency signal from the received high-frequency carrier signal.

In practical application, the frequency band of the carrier is usually divided. For example, in common mobile communication technologies such as 2G/3G/4G, base stations of different operators use carriers in different frequency bands to transmit signals.

With the shortage of communication frequency band resources, more mobile communication base stations will transmit signals with electronic devices in higher frequency bands. However, the inventor found that the higher the frequency of the carrier, the worse the penetration, thus causing a lot of inconvenience to the user. For example, for mobile phone users, the frequency of cellular network (2G, 3G, 4G) is generally above 1G, and the frequency of short-distance WiFi and Bluetooth communication is 2.4GHz/5GHz. The higher the communication frequency, the worse the signal's ability to pass through obstacles. When the user is too far away from the base station and other users outdoors, there will be no signal, which will have a certain impact on personal safety. For example, when a user wishes to send a distress signal through an electronic device, the electronic device may not be able to communicate with the base station if it is in the wild or in a relatively concealed corridor.

Therefore, the inventor proposes an information transmission method, a device and an electronic device in the present application, which can improve the reliability and success rate of information sent by an electronic device.

The operating environment involved in this application is first introduced below.

As shown in FIG. 1 , the environment shown in FIG. 1 includes an electronic device 100 , a mobile communication base station 99 , an IoT device 98 and an IoT base station 97 . Wherein, the electronic device 100 can perform wireless communication with the IoT device 98 through the first frequency, while wireless communication between the electronic device 100 and the mobile communication base station 99 can be performed through the second frequency.

The IoT device 98 may be a sensor that detects analog quantities such as temperature, humidity, and pressure, or may be a device such as a camera that collects images.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 2, an information transmission method provided by the present application is applied to an electronic device, and the method includes:

Step S110: In response to the information sending instruction, the electronic device sends a wireless signal for searching for IoT devices at a first frequency, where the first frequency is lower than the second frequency at which the electronic device communicates with the mobile communication base station.

Wherein, as a way, the information sending instruction is triggered when the electronic device detects a set event. The set event includes one or more physical keys set by the electronic device being pressed. For example, a physical key with an SOS logo may be configured on the electronic device, and when the electronic device detects that the physical key is pressed, an instruction for sending information is triggered. In addition, the set event may also include detecting that one or more physical quantities satisfy the set condition. For example, the physical quantity may be the moving speed of the electronic device, and in this case, the set condition may be that the electronic device detects that the moving speed of the electronic device decreases instantaneously by more than the set value. For another example, in addition to the moving speed, the physical quantity may also include the moving path. In this case, the set condition may include that the electronic device detects that the moving speed of the electronic device decreases instantaneously by more than the set value and moves. The movement direction after the speed reduction is different from the movement path before the movement speed reduction.

It can be understood that, as a method, the communication frequency band used by IoT devices is different from the communication frequency band collected by mobile communication. Bands below 1Ghz.

As a method, the electronic device modulates the carrier signal of the first frequency with the set alarm signal content based on the modulation method of OOK; the modulated signal is sent as a wireless signal for searching for IoT devices. Among them, binary on-off keying (OOK: On-Off Keying), also known as binary amplitude keying (2ASK), is a digital modulation in which the amplitude of the carrier varies with the digital baseband signal (the digital baseband signal is binary). The set alarm content may be three long, three short and three long signal contents, so as to be easily distinguished from other signal contents.

Step S120: If the Internet of Things device is searched, obtain the location information of the electronic device.

It should be noted that all IoT devices can be updated or upgraded in advance, so that the IoT devices can modulate the carrier signal of the first frequency sent by the electronic device with the set alarm signal content (that is, search for the wireless signal of the IoT device). signal) for identification. As shown in Figure 3, when the IoT device recognizes that the received signal is a wireless signal (eg, the SOS signal in the figure) sent by an electronic device (eg, the mobile terminal shown in Figure 3) to search for IoT devices, An acknowledgment signal (for example, an ACK signal) will be returned to the electronic device that sent the wireless signal, and when the electronic device receives the acknowledgment signal sent by the IoT device, it will determine that the IoT device has been searched, and will subsequently send a simultaneous message to the IoT device. A signal that carries SOS signals and location information (eg, GPS location in the figure).

After it is determined that the Internet of Things device is found, the location information of the electronic device can be obtained. Wherein, the electronic device may acquire and store pre-collected location information locally, and may also collect location information in real time through GPS or other sensors.

Step S130: Send the location information to the IoT device, where the location information is used to trigger the IoT device to forward the location information to a designated terminal.

Among them, after receiving the location information sent by the electronic device, the IoT device will forward the location information to the IoT base station or gateway device currently connected to the IoT device, and then the gateway device or IoT base station that has received the location information can Send location information to the specified terminal.

As a way, the IoT base station or gateway device can preselect and store the configured identifier of the designated terminal, so that the IoT base station or gateway device can directly send location information to the stored designated terminal after receiving the location information.

As another way, the location information sent by the electronic device may also carry the configured identifier of the designated terminal. Then, after receiving the location information carrying the identifier of the designated terminal, the IoT base station or gateway device will send the location information to the terminal corresponding to the identifier of the designated terminal carried in the location information. For example, optionally, the IoT base station or gateway device may be connected to a dial-up server, short message server, or mail server. If the IoT base station or gateway device recognizes that the identifier of the designated terminal carried in the location information is a phone number, the Send the number to the dial-up server so that the dial-up server will call the phone number and play the location information when connected. If the IoT base station or gateway device recognizes that the identifier of the designated terminal carried in the location information is an email address, then the IoT base station or gateway device can send an email carrying the location information to the email address.

Wherein, it should be noted that the communication protocol between the electronic device and the Internet of Things device may adopt the existing communication protocol. In this case, the electronic device can modify the data organization structure defined by the adopted protocol, so that a field carrying the location information and the identifier of the designated terminal can be added. And an identification field can be added to the information carrying the designated terminal identification, so that the IoT device can identify.

In an information transmission method provided by the present application, after responding to an information sending instruction, after sending a wireless signal for searching for an Internet of Things device at a first frequency lower than the second frequency at which the electronic device communicates with a mobile communication base station, if searching Go to the Internet of Things device, obtain the location information of the electronic device, and send the location information for triggering the Internet of Things device to forward the location information to the designated terminal to the Internet of Things device, so that the electronic device can facilitate the wear and tear of the terminal. Better transmittance: The first frequency is used to send wireless signals to communicate with the IoT device, so as to send its own location information to the IoT device, so as to improve the success rate of the electronic device sending its own location.

Please refer to FIG. 4, an information transmission method provided by the present application is applied to an electronic device, and the method includes:

Step S210: In response to the information sending instruction, the electronic device obtains the strength of the wireless signal sent by the mobile communication base station at the second frequency.

It can be understood that in the process of sending the location information to the designated terminal, the electronic device can choose to directly send the location information to the designated terminal through the mobile communication base station, or can choose to send the location information to the designated terminal through the Internet of Things device. Then, as a way, the electronic device can first obtain the strength of the wireless signal sent by the mobile communication base station at the second frequency, so as to determine whether to pass the mobile communication according to the strength of the wireless signal sent by the mobile communication base station at the second frequency base station to send location information.

Wherein, as a way, the electronic device may acquire in real time the currently collected strength of the wireless signal sent by the mobile communication base station at the second frequency. As another way to improve the acquisition speed, the stored strength of the wireless signal sent by the mobile communication base station at the second frequency and collected at a set period may also be acquired. In this way, the electronic device can record the collected strength of the wireless signal sent by the mobile communication base station at the second frequency at a set period. For example, it can be configured to store multiple strength values. After the strength of the wireless signal sent by the mobile communication base station at the second frequency, delete the stored strength with the longest storage time, and then check the strength of the wireless signal sent by the new mobile communication base station at the second frequency. storage.

In this case, if the electronic device detects that the stored intensity values arranged according to the collection time show a decreasing trend, the electronic device can send the location information carrying the alarm signal content to the base station once, so as to avoid the subsequent loss of signal intensity due to the signal intensity. If the value is not sufficient for normal communication, the location information that carries the content of the alarm signal cannot be successfully sent to the mobile communication base station.

Step S220: Detect the strength of the wireless signal sent at the second frequency.

It can be understood that, when the electronic device detects the strength of the wireless signal sent at the second frequency, it is to detect whether the strength value satisfies the set condition.

It should be noted that if the electronic device does not acquire the wireless signal sent at the second frequency, it is determined that the strength of the wireless signal sent at the second frequency is 0.

Step S230: If the strength satisfies the set condition, send the location information of the electronic device to the mobile communication base station.

Step S240: If the strength does not meet the set condition, send a wireless signal for searching for IoT devices at a first frequency, where the first frequency is lower than the second frequency at which the electronic device communicates with the mobile communication base station.

As an approach, the preset condition includes at least one of the following conditions:

The strength of the wireless signal sent by the second frequency is higher than the set strength value within the set time period; and

The variation range of the strength of the wireless signal sent by the second frequency is smaller than the set range threshold within the set time period.

Step S241: If the Internet of Things device is searched, obtain the location information of the electronic device.

Step S242: Send the location information to the IoT device, where the location information is used to trigger the IoT device to forward the location information to a designated terminal.

In an information transmission method provided by the present application, after responding to an information sending instruction, when it is detected that the strength of the wireless signal sent at the second frequency does not meet a preset condition, the method is lower than that between the electronic device and the electronic device. After the first frequency of the second frequency communicated by the mobile communication base station sends the wireless signal for searching for the Internet of Things device, if the Internet of Things device is searched, the location information of the electronic device is obtained, and the information for triggering the Internet of Things device is sent to the Internet of Things device. The IoT device forwards the location information to the designated terminal location information, so that the electronic device can send a wireless signal to the first frequency for better penetration rate to communicate with the IoT device, so as to send its own location to the IoT device information, so as to improve the success rate of the electronic device sending its own location.

Please refer to FIG. 5, an information transmission method provided by the present application is applied to an electronic device, and the method includes:

Step S310: In response to the information sending instruction, the electronic device sends a wireless signal for searching for IoT devices at a first frequency, where the first frequency is lower than the second frequency at which the electronic device communicates with the mobile communication base station.

Step S320: If the Internet of Things device is searched, the identifier of the Internet of Things device that is searched for is acquired.

As a method, unique identifiers can be assigned to different IoT devices in advance, then when the IoT device returns a confirmation signal to the electronic device, the unique identifier can be carried in the confirmation signal, so that the electronic device can obtained.

Step S330: Acquire location information corresponding to the identifier from pre-stored location information of the IoT device.

As a method, the identification of the IoT device that currently supports the identification of the wireless signal sent by the electronic device to search for the IoT device and the corresponding location information may be stored in a public server. Then, the electronic device can request from the public server in advance the stored identifier of the IoT device that currently supports the identification of the wireless signal sent by the electronic device to search for the IoT device and the corresponding location information, and then store it locally. As a way to save storage space, the electronic device may only obtain the identification and corresponding location information of the IoT device in the current area that supports the identification of the wireless signal sent by the electronic device to search for the IoT device. Among them, the area can be an area customized according to longitude and latitude, or can be an administrative area.

In this case, the electronic device may determine whether the current area needs to be reacquired according to the state of its own location. For example, if the area is a user-defined area based on longitude and latitude, and the electronic device detects that its own location information has exceeded the previous area, it starts to re-acquire search objects sent by the electronic device that supports the identification of the current area. The identification of the Internet of Things device and the corresponding location information of the wireless signal of the Internet-connected device. However, if the area is an administrative area, when the electronic device detects that it is no longer in the previous administrative area, it starts to re-acquire the Internet of Things in the current area that supports identifying the wireless signal sent by the electronic device to search for Internet of Things devices The identification of the device and the corresponding location information.

Step S340: Obtain the distance from the searched IoT device.

Among them, it can be understood that the wireless signal will be attenuated correspondingly with the increase of the transmission distance, then as a method, the electronic device can determine the electronic device according to the signal strength (for example, RSSI value) of the received signal sent by the IoT device. Distance from IoT devices. In this case, the electronic device can determine the distance d from the searched IoT device according to the formula d=10^((abs(RSSI)-A)/(10*n)), where RSSI is Received signal strength (negative value), A is the signal strength when the transmitter and receiver are separated by 1 meter, and n is the environmental attenuation factor. It can be understood that, due to different environments, the corresponding parameter values (such as the aforementioned parameters A and n) of each emission source (such as an Internet of Things device) may be different. Then optionally, each parameter in the formula can be obtained by experiment (calibration), or it can be directly assigned an empirical value. For example, 59 can be assigned to A and 2 to n.

Step S350: Calculate and obtain the location information of the electronic device based on the distance and the location information corresponding to the identifier.

In one way, the location information is latitude and longitude, and the step of calculating the location information of the electronic device based on the distance and the location information corresponding to the identifier includes: determining the searched Internet of Things The azimuth of the device relative to the electronic device, extending the azimuth, and adjusting the distance corresponding to the position information corresponding to the identifier to obtain the position information of the electronic device. It can be understood that the wireless signal will be transmitted in all directions during the transmission process, so the electronic device may receive the wireless signal transmitted from the same signal source transmitted from multiple directions, and the signal transmitted from different directions will be The transmission path is different, and there is a difference in strength, then the electronic device can judge the relative position between the searched Internet of Things device and the electronic device according to the strength difference. For example, the source direction of the strongest signal may be determined as the location of the searched IoT device relative to the electronic device.

Among them, it should be noted that the wireless signals transmitted from the same signal source transmitted from multiple directions and received by the electronic device are wireless signals that carry the same content and are simultaneously sent by the Internet of Things device.

As shown in Figure 6, the electronic device can measure a directional angle (α in the figure) according to the detected orientation of the IoT device relative to itself, then when the latitude and longitude of the IoT device is obtained, it can The included angle direction, that is, the position where the distance between the calculated and searched IoT devices is moved in the direction indicated by the arrow in the figure can be identified as the position of the electronic device, thereby obtaining the position information of the electronic device.

It is understandable that when the electronic device is in a relatively hidden corridor or an area with serious signal occlusion, it may not be able to obtain accurate location information in real time through GPS, so that the electronic device cannot immediately send effective distress information. The location information of the IoT device is pre-collected and set, so it can be considered as accurate location information, and then the location information of the electronic device is calculated according to the distance and relative orientation from the IoT device, so as to improve the The accuracy and immediacy of the location information obtained by the electronic device are improved, so that the electronic device can instantly send effective distress information.

Step S360: Send the location information to the IoT device, where the location information is used to trigger the IoT device to forward the location information to a designated terminal.

In an information transmission method provided by the present application, after responding to an information sending instruction, when it is detected that the strength of the wireless signal sent at the second frequency does not meet a preset condition, the method is lower than that between the electronic device and the electronic device. After the first frequency of the second frequency communicated by the mobile communication base station sends a wireless signal for searching for the Internet of Things device, if the Internet of Things device is searched, the location information of the electronic device is obtained based on the stored location information of the Internet of Things device, and the information is sent to the Internet of Things device. The IoT device sends the first frequency for triggering the IoT device to forward the location information to a designated terminal, so that the electronic device can send a wireless signal to communicate with the IoT device at the first frequency that facilitates better penetration. , so as to send its own location information to the IoT device, so as to improve the success rate of the electronic device sending its own location. Moreover, because the electronic device obtains its own location information through the location information of the IoT device, the accuracy of the location information is improved.

Please refer to FIG. 7 , an information transmission method provided by the present application is applied to an Internet of Things device, and the method includes:

Step S410: After receiving the search signal sent by the electronic device, return a determination signal to the electronic device.

Step S420: Receive the location information returned by the electronic device in response to the confirmation signal.

Step S430: Send the location information to the IoT base station, where the location information is used to trigger the IoT base station to forward the location information to a designated terminal.
