摘要
本文提供一种对多个报警量的采集及处理有效方法,利用MCS—51单片机对传感器送来的温度、压力、液位等电信号进行转换并超限判断,具有声光报警功能,而且显示相应的报警号。
Abstract In this paper, we provide a efficient method for simpling and processing multialor quantities, it uses MCS -51 single-chip processor to convert electro-signals, such as temperature, pressure and liquard-position, predicate orerlimit. It has the func-tion for audio and light alarming, displays corresponding alarm number.
