基于单片机的陶瓷窑多点温度检测系统

A Real-time monitoring system of China stove multi-spots temperature by single-chip microcomputer

系统以51单片机为核心,利用K型热电偶作为传感器,对陶瓷窑中多点温度进行监控,通过串行通信,可供PC机上绘制温度变化曲线图的技术人员分析问题,并设计了新颖的冷端补偿电路和通用查表法,本系统成本低,测温精度高,可靠实用.

In this system single chip microcomputer is the core, K thermocouple is the sensor. The temperatures of many spots in china stove were monitored. By serial communication, graph of temperature changing can be drawn, technologist can analyze problem by these picture. At the same time, a new cold point compensated circuit and a general look-up table method were designed. The cost of this system is low and it is reliable and practical.
