Central control device of remote wireless control system

Abstract

The invention provides a central control device of a remote wireless control system. A central processor module achieves control logic of an entire circuit, a remote signal input module is connected with an external data input device and receives an external data signal and sends the data to the central processor module for processing, and a serial communication module and a wireless local area network module perform remote communication with a field control device matched with the central control device, send instructions to the field control device and receive information feedback from the field control device. The central control device can perform remote communication with the field control device matched with the central control device, and the limitation that transmission required bycontrol is completed only through hard wiring of the control circuit or short-distance wireless communication is overcome. Moreover, a two-way communication mode is added, a specific communication mode is selected according to the priority of the response speed for long-distance communication, the respective advantages of two-way communication are utilized, and the respective disadvantages of two-way communication are avoided.

Description

technical field [0001] The invention relates to the technical field of remote monitoring and control systems, in particular to a central control device of a remote wireless control system. Background technique [0002] If a traditional relay control system wants to perform a control action, it needs to use wires to connect control switches, control buttons, sensors, etc. Then use the output device to control the shutdown or operation of the controlled object. In this control system, the transfer of control requirements must be completed through the hard wiring of the control circuit. [0003] However, wired connection will be limited by factors such as distance and environment, and can only be implemented in a small area, which is increasingly unable to meet the control requirements of modern society. Therefore, a relay control system capable of wireless connection is needed, and the relay control system expand. [0004] In recent years, many companies have also used the B...

[0003] However, wired connection will be limited by factors such as distance and environment, and can only be implemented in a small area, which is increasingly unable to meet the control requirements of modern society. Therefore, a relay control system capable of wireless connection is needed, and the relay control system expand

[0004] In recent years, many companies have also used the Bluetooth mesh networking method in the relay control system, replacing the wired connection with a wireless connection to avoid the difficulty of wiring in the system, but this method only solves the problem of wiring. Difficult, still unable to achieve remote control

[0005] For example, in the deodorization system of the landfill site, there are wind guns, spray pipes, gas concentration sensors and other devices that need to be controlled. Because there is a large amount of odorous gas in the landfill site, the odorous gas will affect the human body's breathing, digestion, heart, and so on. The blood vessels and endocrine system will cause different degrees of poisoning. It is obviously unreasonable to set the control room of the deodorization system around the landfill, and for a large-scale landfill, only one short-distance wireless control is required. The control room can't meet the requirements
