GPRS烟气在线监控系统的设计

阐述了采用完全抽取方式的GPRS烟气在线监控系统的功能和构成。该系统从功能上分为烟气信息监测监控收集子系统、烟气信息加工及处理子系统和环境管理决策支持及信息发布子系统，结构上分为监测点和监控中心两部分。监控中心包括省级监控中心和市级监控中心，监测点包括仪器分析单元、控制单元和通讯系统。指出基于中国移动GPRS／GSM的烟气数据监控系统具有建设使用成本低、监测监控范围大、积木化结构、技术先进和数据并行收取等特点，具有广阔的应用前景。

Design of GPRS Flue Gas On line Monitoring System

The function and component of GPRS flue gas on-line monitoring system, which was complete extractive model, were discussed. From function, this system can be divided into collection sub-system of flue gas information monitoring, treatment sub-system of flue gas information monitoring and environmental decision support and information distribution system. From structure, it can be divided into monitoring-site and monitoring center. Monitoring center was divided into provincial center and municipal center. Monitoring site can be divided into instrument analysis element, control element and communication element. This system is based on GPRS/GSM(Chinese Mobile Communication Company) communication net. It has low construction cost, large monitoring area and combining structure. And it was technology-advanced, and has more applied market.
