Abstract
The utility model relates to a one-master multiple-slave communication circuit. An aim of the utility model is to provide a novel communication circuit which has the following advantages: no requirement of address code by the slave sets, no number limitation, high convenience in capacity expanding, no adoption of a chip by the communication circuit, strong interference resistance and high antistatic capability. For realizing the purpose of the utility model, a technical solution is adopted, wherein the one-master multiple-slave communication circuit is characterized in that: the communication circuit comprises a master computer and a plurality of slave computers; the master computer is connected with the plurality of slave computers through a signal wire, a ground wire and a feedback wire. The mater computer transmits information for each slave computer through the signal wire with a broadcast mode. The plurality of slave computers are connected with the host computer through one feedback wire with a wired-and mode.
Description
Technical field
The utility model relate to a kind of one much more main from communicating circuit, specifically be a kind of slave need not geocoding, quantity unrestricted, can make things convenient for dilatation, communicating circuit does not adopt chip, strong jamproof novel communication circuit is arranged.
Background technology
A current master is many generally to need to establish slave addresses from communicating circuit, and the slave restricted number is arranged, and project installation or System Expansion inconvenience are anti-interference very poor with antistatic effect.
Summary of the invention
The purpose of this utility model be for provide a kind of slave need not geocoding, quantity unrestricted, can make things convenient for dilatation, communicating circuit do not adopt chip, the novel communication circuit of strong anti-interference and antistatic effect is arranged.
For realizing the purpose of this utility model, adopt following technical scheme: a kind of one much more main from communicating circuit, it is characterized in that: this communicating circuit comprises a upper main frame and several the next slaves, upper main frame is connected by holding wire, 3 lines of ground wire and feedback line with some the next slaves, upper main frame sends information by holding wire to each slave with broadcast mode, and some slaves are connected with upper main frame with mode with line by a common feedback line.
Preferably, described upper main frame, comprise MCU, driver module, input, output and Shaping Module, the MCU of upper main frame links to each other with driver module, driver module links to each other with the next slave of ground wire and each by holding wire, each the next slave links to each other with the Shaping Module of host computer with feedback line by ground wire, and Shaping Module links to each other with upper main frame MCU.
Preferably, described the next slave, MCU, receiver module and the line and the module that comprise the next slave, holding wire links to each other with the receiver module of ground wire and the next slave, receiver module links to each other with the MCU of the next slave, the MCU of the next slave links to each other with module with line, and the line of each the next slave links to each other with upper main frame with feedback line by ground wire with module.
Operation principle is as follows: upper main frame MCU will convert digital signal to by A/D from the signal that transducer is read, gather other input signal well, MCU handles, data, order, verification and communications protocol according to the rules that needs are handed down to slave sort and are stored in the array,, after the driving force of the drive circuit enhancing signal that triode is formed, upper main frame need be sent to data, order and the verification of the next slave and sends to each slave by the output of I/O mouth via holding wire and ground wire.After the receiver module of slave computer receives the data that host computer issues, will by verification and data give MCU decoding, read each corresponding parameters value and each order, slave computer input signal that reads in conjunction with the next slave MCU and corresponding programmed algorithm, carry out corresponding output control, the next then slave MCU exports the operating state of the next slave by line and module, when output was implemented as normality: line and module were output as high level; Output is implemented as when abnormal: line and module are output as low level, the state feedback line level of slave is dragged down, the state feedback line that the MCU of upper main frame detects the next slave is low, knowing has the next slave to carry out relevant control action, thereby it is corresponding with the operating state of the next slave that corresponding upper main frame is carried out relevant output, and above process has been finished the communication of the many slaves of a main frame.
