[Abstract]:At present, the auxiliary transportation system in underground coal mines basically uses winch hoist transportation mode, but the control technology of inclined roadway hoisting winch is still relatively backward. Winch drivers control the winch's start and stop action according to the number of times they hear the sound. Although the communication can be carried out by means of interphone and signal worker, there still exists the situation of improper operation. The research of intelligent winch communication system is urgent, and it has important application value and broad application prospect. In this paper, a winch communication system is designed. According to the functional requirements of the winch communication system, the schematic diagram of the system structure is drawn, and the working principle of the system is briefly described. This paper introduces the hardware structure of the system, analyzes the installation and layout of the hardware structure, designs the power supply circuit of the system, the microcontroller and its peripheral circuit, the carrier circuit and the power amplifier circuit, etc. The system is mainly composed of a winch controller and several acousto-optic signalling devices. The winch controller is located at the top of the inclined roadway. The acousto-optic signal device is installed along the inclined roadway according to the actual working requirements of the inclined roadway. The winch controller and acousto-optic signalling device adopt the power carrier technology. With the help of downhole power line, signal transmission, such as speech and so on, reduces the complexity of line installation and saves communication cost. The acousto-optic signalling device and winch controller adopt 8 bit and 32 bit single chip microcomputer respectively, which provide a good guarantee for the realization of system function. The system software is designed, and the architecture based on 渭 COS- 鈪，
