Remote control system for electromagnetic speed-regulating coal mining machine

Abstract

The invention relates to a remote control system for an electromagnetic speed-regulating coal mining machine, and aims to solve the problems of high power consumption, low reliability, waste of system resources and the like of existing remote control systems. The remote control system comprises a main wireless remote control unit and an auxiliary wireless remote control unit. An ultralow-power-consumption CPU-STM8L152C6T6 serves as a core processor of the main wireless remote control unit to realize design of various circuits such as a power source circuit, a wireless transceiving circuit, a keying circuit and the like. The auxiliary wireless remote control unit takes STM8L15C6T6 as a control core and takes a Modbus interface circuit as a hardware platform. The wireless transceiving circuit is realized by the aid of a Si4432 based wireless radio frequency chip, the auxiliary wireless remote control unit is connected with a master control system of the coal mining machine through a RS485 bus, and data transmission between the auxiliary wireless remote control unit and the master control system of the coal mining machine is realized according to a Modbus protocol. The remote control system for the electromagnetic speed-regulating coal mining machine has the advantages that keys on a panel of the main unit are remotely controlled to send related control instructions which are transmitted wirelessly, and the auxiliary wireless remote control unit receives and analyzes data, stores related data into corresponding registers and transmits the data to an electric control system of the coal mining machine so as to control operations of the coal mining machine.

Description

technical field [0001] The invention relates to the technical field of remote control systems for electromagnetic speed-adjusting coal shearers, in particular to a bus-type remote control system based on Si4432 wireless radio frequency chips. Background technique [0002] The coal mining machine is related to the coal mine field, and is one of the most important equipment in the production activities of the coal mine field. The reason is that the correct operation and control operation of the coal mining machine is related to the production efficiency of the coal mining work and the maintenance and maintenance cost of the coal mining machine. [0003] A manual operation mode of the shearer is controlled by an on-board controller, that is, it is operated through a control panel installed on the shearer body. The disadvantage of this mode of operation is that the control of the shearer through the on-board controller is limited by harsh environmental factors such as dust and ...

Problems solved by technology

Although the program processing of this kind of remote control is simple, the reserved points of the electronic control system not only make integration more difficult, but also make it difficult to expand functions and occupy system resources.

At the same time, due to the narrow space of underground tunnels, high air humidity, high mobility of equipment and workers, and large fluctuations in power supply voltage, the communication situation in underground mines is poor.
