Abstract: In order to solve the problems that data can not be unified access, the response is not timely and low degree of intelligence in monitoring system for central substation of coal mine, the distributed intelligent acquisition and analysis system has been developed for the central substation in the underground coal mine. Based on the main processors Exynos4412, NVIDIA Jetson TX2 processor and FPGA processor, the infrared imaging sensor circuit, vibration signal acquisition circuit, current signal acquisition circuit and TEV signal acquisition circuit etc. are designed. The application software of intelligent acquisition and analysis terminal is realized based on downhole loop network and Linux system coding. After testing, the system developed in this paper has an average packet loss rate of 0.114% and an average response time of 1.685 seconds.The intelligent acquisition and analysis terminal developed in this paper can provide fault diagnosis service and improve the intelligent level of coal mine.
