Indoor Temperature Gathering Telephone in Automatic Heating Control

应用于供暖自动控制中的室温采集电话除了具有普通电话机的功能外还具有采集室温的功能。室温采集电话通过公共电话网络,接收到室温采集基站的请求后将温度上传至PC机,构成远程温度采集系统。本文基于普通电话的通话电路用HT95C30P微控制器和温度芯片LM92设计和实现室温采集电话。

The indoor temperature gathering telephone used in campus energy-saving heating control has the function of gathering indoor temperature besides the functions of common telephone.Through public telephone network,the phone sends the indoor temperature to the PC after received the request of the temperature gathering base station to compose the longdistance temperature gathering system.This paper introduces the design and realization of the telephone using HT95C30P microcontroller and LM92 temperature sensor based on the talking circuit of common telephone.
