基于GPRS的中央空调远程监控系统设计

远程监控系统对于中央空调系统的节能、集中管理、维修以及远程诊断有重要的意义。设计了一种基于中国移动GPRS的通信架构，实现中央空调制造商从中国大陆任意通过中国电信接入因特网的PC上监控位于中国大陆的中国移动GSM覆盖网络下的任意中央空调机组。与其他中央空调监控系统相比，具有应用范围广、成本低、数据实时性好的特点。

Design of Remote Monitoring System for Chiller Based on GPRS

The remote monitoring system is very important for energy saving, centralized management, service and remote diagnosis of chiller. This article shows a communications architecture based on the GPRS of China Mobile. With this communications architecture, the chiller manufacture’s PC which link to Internet by China Telecom can monitor any chiller in any position with the GSM network of China Mobile in the mainland of China. In comparison with the monitoring system related for chiller, this communications architecture has the advantage of large applied range, low cost and good real-time performance.
