针对矿井综合采煤区布线复杂、易发生漏电的现状,设计了一种以TMS320F2812为核心处理器的漏电保护样机,该样机采用一种人工智能策略进行信息融合判漏的新方法。介绍了基于D-S证据理论法和模糊理论法的暂稳态智能融合选漏方法、漏电保护装置及人机交互界面的在线监测的设计。通过实验,该样机具有选择性、快速性、灵敏性、智能性。 Aiming at the current situation that the coal mine is complicated and prone to earth leakage, a prototype of leakage protection with TMS320F2812 as its core processor is designed. This prototype uses a new method of artificial intelligence for information fusion. This paper introduces the method of temporary steady-state intelligent fusion selection and leakage based on D-S evidence theory and fuzzy theory, the design of on-line monitoring of earth leakage protection device and human-computer interaction interface. Through experiments, the prototype is selective, rapid, sensitive and intelligent.
