Study on the Two-stage Bus-Mastering Computer Temperature Detecting System

介绍了一种新型的两级总线型电子冷藏箱温度检测系统。研制设计了温度智能控制器的总线型温度检测电路 ,甩掉了从传感器、变送器、多路开关到A/D转换器的传统模式。该系统成功地解决了多点、远距离温度测量的线路驱动和时序配合问题。设计了硬件去抖动电路 ,并巧妙地把网络中“令牌”传递技术移植到温度检测系统中 ,具有显著的应用和推广价值。

A new two stage bus mastering computer temperature detecting system is presented in this paper. The bus temperature detecting circuit of intelligent temperature controller is designed, which throws off the traditional pattern of sensor, translator, multiplexer and A/D converter. This system successfully solves the circuitry driving and time sequence fitting problem in many spot and remote temperature detecting. The hardware circuit is designed to get rid of dither and the token ring transferring technique of network is skillfully integrated to the temperature detecting system, which has notable application and popularization values.\;
