井口安全报警系统研究

Study of a Pithead Alarm System

分析了在煤矿井口特殊环境下用以识别传送带上人的传统模式识别方法所存在的问题以及人在传送带上的特征，提出了与之相对应的安全报警系统模型。给出了基于由复合红外探头和单片机组成的安全系统的实现方案，并讨论了该系统的性能。

This paper points out the problems of the traditional pattern recognition method for distinguishing a person on the coal conveyer belt in the special environment of coalmines, analyses the posture features of the person on the conveyer belt, and then presents a relative pithead alarm system model. Based on the model, a practicable system which is composed of a compound infrared detector and a single-chip microcomputer is given. The system performance is discussed.
