Abstract

The invention discloses a method and device for allocating addresses to slave devices and a storage medium, and the method specifically comprises the steps: firstly enabling the master device to broadcast a device discovery full-query message, enabling the slave devices which are not configured with device addresses to return a first response message carrying a device ID corresponding to the slavedevices when receiving the device discovery full-query message, and according to the first response message, sequentially sending a first address allocation message carrying the device ID and the newly allocated device address to each slave device corresponding to the first response message; when the slave device receives the first address allocation message, judging whether the device ID carriedby the first address allocation message is consistent with the slave device, and if the device ID carried by the first address allocation message is consistent with the slave device, setting the equipment address carried in the first address allocation message to take effect. According to the embodiment of the invention, through automatic discovery and automatic allocation of the device address of each slave device, the problems of low efficiency and error proneness during manual device address configuration are solved, and the efficiency and accuracy of communication between the master device and each slave device are improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device, storage medium and system for allocating addresses for slave devices. Background technique [0002] RS-485 is a standard defining the electrical characteristics of drivers and receivers in a balanced digital multipoint system, defined by the Telecommunications Industry Association and the Electronic Industries Alliance. It is mainly a serial bus standard that uses balanced transmission and differential reception. The digital communication network using this standard can effectively transmit signals under long-distance conditions and in environments with high electronic noise. RS-485 makes it possible to configure low-cost local networks and multi-branch communication links. It is widely used in industrial, mining, transportation and other enterprises, and the communication distance can reach tens of meters to thousands of meters. [0003] T...
