As the coal mining industry advances from shallow to deep, environmental conditions such as temperature, pressure, and vibration need to be monitored at all times to prevent phenomena that threaten the safety of personnel and property in the mine. Therefore, a real-time, stable collection and transmission system Extremely important. To solve this problem, a multi-channel, digital-analog hybrid acquisition and real-time transmission system based on FPGA is designed. On the basis of the overall design of the system, the hardware circuit and software program design of the system are introduced. Through the simulation of the program, the feasibility of the acquisition and transmission system design is verified. It has been verified by physical experiments that the acquisition and transmission system can correctly and effectively collect and transmit the signals output by the five sensors, and the accuracy of each signal meets the requirements, which has certain engineering practical value.
