Abstract

The embodiment of the invention discloses a communication slave, a master-slave device communication system and a communication method. According to the technical scheme provided by the embodiment of the invention, the communication host sends the number response command to the communication slave, and the communication slave detects the voltage of the slave interface through the voltage detection module after receiving the number response command to obtain the voltage detection result; the slave master control module determines the reply time of the serial number response command according to the voltage detection result, and sends the serial number response information to the communication bus through the slave communication module at the reply time, and the communication host can number the communication slaves according to the serial number response information received at different reply times. And a worker does not need to manually set a number for each communication slave, so that the numbering efficiency of the communication slave is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communication, and in particular, to a communication slave, a master-slave device communication system, and a communication method. Background technique [0002] In the bus communication of master-slave devices, one communication master corresponds to multiple communication slaves, and the communication master sends commands to the slaves by broadcasting. After the slaves receive the commands sent by the master, the corresponding slaves can reply to the communication master. Information to prevent multiple communication slaves from sending signals to the communication master at the same time, causing communication conflicts. Therefore, it is necessary to set a unique slave number for each communication slave. [0003] In the prior art, the numbering method of communication slaves is generally through software programming or chip identification, and a unique slave number is set ...
