Online Upgrading Technology for Mine-used Sensor Based on ISP Technology

Mine sensors are usually installed in the working conditions with relatively strict conditions. Due to the addition and deletion of later business functions and early application bugs, we need to constantly update the procedures. The traditional method updates the program on the ground, and then changes the motherboard underground. This method takes time and effort. In order to solve this problem, the ISP online upgrading technology is studied. The storage Flash of the ARM processor is used as the carrier, the former part stores ISP online upgrade code, and the later part stores the program that the mine-used sensors need to be updated. The goal of online upgrading of mine sensor is realized.
