Wireless communication device and method for remote dual protection control

Abstract

The invention belongs to the technical field of automation control, and particularly relates to a wireless communication device for remote dual protection control. The wireless communication device comprises a wireless transmitting device mounted in a stacker-reclaimer PLC electrical room and a wireless receiving device mounted in a large belt PLC electromagnetic station; the wireless transmitting device comprises a wireless communication module, a controller, a wireless communication module antenna and a digital quantity signal input terminal strip; and the wireless receiving device comprises a wireless communication module, a controller, a wireless communication module antenna, an output relay A, an output relay B and an output relay open point terminal strip. The problem of incapability of wiring in a complex environment or high wiring cost of a small quantity of signals is avoided; full-coverage monitoring of related equipment is achieved; complex communication transmission protocol and communication path configuration and reading of wired communication between the two are simplified; safety accidents caused by wrong signals are avoided; and equipment safety accidents caused by the fault state of the wireless transmission equipment are prevented.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and is applied to the automatic control of stackers and reclaimers. It specifically relates to a wireless communication device for remote dual protection control, and also relates to a wireless communication device for remote dual protection control. communication method. Background technique [0002] As a new type of high-efficiency continuous loading and unloading machine, the stacker-reclaimer is widely used in daily production. It is mainly used in bulk cargo terminals, iron and steel plants, large thermal power plants and mines and other bulk material storage yards. , consisting of four parts: running mechanism, bucket wheel mechanism and slewing mechanism. In the automatic control, the stacker and reclaimer is an independent Siemens and Quantum control system in the electric room on the machine, and the control system composed of Rockwell is in the large belt under the machine.
