Embodiment Construction

[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053]Generally speaking, when a master device needs to communicate and control multiple independent slave devices, the master device needs to correlate the received information with the information source. In order to remotely control multiple slave devices, the master device needs to establish multiple communication channels in advance, communicate with multiple slave device termin...

Abstract

The invention provides a communication method and device based on an automatic control system, and relates to the technical field of automatic control. The automatic control system comprises a masterdevice and at least one slave device. The slave device communicates with the master device through a single channel, the method is applied to the first slave device, and the first slave device is anyone of the slave devices. The method comprises: receiving a first message broadcasted by the master device through the single channel, and the first message comprising a payload and a second slave device ID; judging whether the ID of the first slave device is matched with the ID of the second slave device or not; and if yes, executing the operation task according to the effective load of the firstmessage, relieving communication channel number limitation and bandwidth consumption, and solving the problem that the number of slave devices is limited.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a communication method and device based on an automatic control system. Background technique [0002] In different practical application scenarios of automatic control equipment, in order to enable the master device to remotely control multiple devices, a communication network is usually established between the master device and multiple slave devices, so that the master device can monitor and control multiple slave devices in the communication network Devices, slave devices can also communicate with the master device in the communication network. [0003] At present, due to the limitation of the communication module, the limitation of the number of channels, and the limited bandwidth resources, and the consumption of communication bandwidth is large, the number of slave devices that can be controlled by the master device is limited, and it cannot be applied to the actu...
