摘要
在介绍某型机电式温度表组成及工作原理的基础上,论述了基于MCS-51单片机的数字温度表的设计方法,给出了硬件电路设计、模拟电源与放大器电路设计及软件设计,用AEDK51仿真器完成了硬软件调试。该设计克服了机电式温度表摩擦、温度变化等因素引起的指示误差大的弊端,提高了温度表的指示精度。
In this paper the composing and principle of one type electromechanical thermometer are introduced, then the design of digital thermometer based on SCM is discussed in detail, the design and debugging using AEDK51 simulator of the hardware circuit and software are also given. The digital thermometer with high indication precision overcomes the large indication error shortage of electromechanical thermometer because of friction and temperature variation.
