本文阐述了具有数据采集、数据通信和数据处理三层系统结构的中央空调微机监测系统结构原理及实现方法。该系统以单片计算机作为数据采集前端机,以486微型计算机为空调工况监测主机,并通过电流环串行通信方式实现监测主机与数据采集机之间的数据传输。
This paper describes the structure and implementation of a central air conditioning microcomputer monitoring system with data acquisition, data communication and data processing three-tier system structure. The system uses single-chip computer as data acquisition front-end, 486 microcomputer as air-condition monitoring host, and realizes the data transmission between host computer and data acquisition machine through current loop serial communication.
