Remote control system for electromagnetic speed-regulating coal mining machine

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.
