Abstract

The invention discloses a power device linkage control method, system and device. The method is suitable for a linkage control system comprising a host and a plurality of slave devices, the host and the slave devices are connected in sequence to form a series structure which is started from the host and is ended at the last slave device, each slave device is connected with a power device, and a control signal sent by the host or the previous slave device is received; the control signal is processed and then is output to the power device connected with the current slave device, so as to controlthe power device connected with the current slave equipment; the control signal is sent to the next slave device, so that the next slave device processes the received control signal and then outputsthe processed control signal to a power device connected with the next slave device, and the control of the power device connected with the next slave device can be realized, and the communication protocol between the devices can be simplified, the anti-interference capability is enhanced, linkage control and expansion are convenient, implementation is easy, and cost is reduced.

Description

technical field

[0001] The invention relates to the field of power relay groups, multi-channel equipment and display and control equipment, and in particular to a power equipment linkage control method, system and device. Background technique

[0002] Most of the existing multi-channel power equipment control systems use RS232 / RS485 for communication, see figure 1 as shown, figure 1 It is a structural block diagram of a multi-channel power equipment control system provided by the prior art, including a master 00 and M slaves, where M is an integer greater than 1. When the control system is working normally, the master 00 and slaves 01 to 0 The slave 0M communicates through RS232 / RS485, so as to realize the linkage control of the master 00 to the M slaves.

[0003] but, figure 1 The slave 01-slave 0M of the multi-channel power equipment control system provided in the prior art all need to be equipped with a communication chip to realize communication with the master 00, re...

Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] see figure 2 as shown, figure 2 It is a method flow chart of a power device linkage control method provided in Embodiment 1 of the present invention. The power device linkage control method is applicable to a linkage control system including a master and several slave devices. The master and the slaves are sequentially Connecting to form a series structure starting from the host and ending with the last slave device, each slave device is con...
