Intelligent Photoelectric System for Underground Locomotive Positioning

This paper designed a set of intelligent adaptive photoelectric system for underground locomotive positioning, it combined the high-performance ARM7 processor with the advanced photoelectric decode sensor SOC2111, used analog switch to achieve multi-route sensors timeshared detection. Through 232 and 422 bus, the data would be sent to the upper computer for application processing. The test results showed that the system had advantages, such as simple structure, high-speed and strong anti-interference ability.
