Detecting System of the Temperature and Moisture for Cold Storage by the Computer

本文介绍了一个冷库温、湿度计算机检测系统.对温、湿度传感器的选用作了分析、比较,介绍了所采用的信号中转放大、分时检测传输技术、软件滤波技术和串行通讯技术、这些技术的应用是达到较高检测精度的保证.在车间采用大屏幕显示;在办公室设置管理计算机,它们与车间间控制室的的检测计算机形成计算机网络.实践证明,这是一个融检测、控制及管理为一体的个性能优良的计算机系统.

This paper introduces a detecting system of the temprature and moisture for cold storage by the computer. It is analyzed and compared selectrng the sensers of the temprature and moisture. It is introduced using technique of signal middle amplify transforma-tion, detecting by time sharing, software filter and series communication. So the higher detected precision was achieved. A computer net was formed by the big screen in the shop, the managing computer in the office and the detecting computer in the shop control room. Fact indicates that this system is a excellent computer system which gets together the detecting, controlling and managing.
