摘　　要：采用市场上容易获得的称重传感器、位移传感器、热电偶、霍尔传感器等传感器构成测控实验系统,对重量、位移、温度和转速等物理量进行测试、监控和显示。硬件部分包括各传感器信号调理电路模块以及由AD 574A,89C 52,8255A等构成的主板模块。由于采用模块化设计,使用灵活,且很容易增加测量传感器的种类。系统稳定,操作简便,能有效地培养学生的实践动手能力和工程应用能力。Using weighting sensor, displacement sensor, thermocouple, Hall sensor and so on which we can buy easily in market to constitute measuring and controlling experimental system. We use it to measure, control and display parameters such as weight, displacement, and temperature, rotational speed and so on. Its hardware interface includes sensor signal condition circuits and the motherboard constructed by AD574A, 89C52, 8255A, etc. Because the experimental system consists of the modules, it is convenient to use, and sensor is added easily. The system is stable and operated simply. It can increase students＇ ability of operating and practicing.
