CKWJ—A型烟草仓库微机监控系统接口电路的设计

DESIGN OF THE CKWJ—A TYPE TOBACCO WAREHoUSE MICROCOMPUTER MONITOR SYSTEM INIERFACING CIRCUIT

本文介绍了CKWJ-A型烟草仓库微机监控系统接口电路的设计。它包括了温度转换电路,湿度转换电路,为温、湿度转换电路共用的放大电路,A/D转换电路等的设计,它能巡回采集湿度的数据,同时直接控制空调机和去湿机,还可以处理火、盗警的探测及报警。图8,表1,参5。

In this article, a CKWJ-A type tobacco warehose microcomputer monitor system interfacing cicuit design is described, includig the temperature and the humitity conversion circuits, the both use amplifier circuit for the temperature and the humitity conversion, A/D conversion circuit and so on. The microcomputer monitor system can collect eight lines temperature and eight lines humitity datum, and directly control eight air-conditioners and eight dehumitifires, and can also detect the fire and the sted warning, and warn in time. 8figs, ltab, 5refs.
