摘要
城市的水网、气网和环保领域都需要连续对现场的物理参数进行监测,并通过网络将监测数据传送到管理中心进行数据处理、分析和管理。针对各种监测领域数据处理的工作特点及要求,提出了系统主要实现的功能。详细地叙述了基于GSM网络的进行数据传输时采用的主要AT命令的作用和使用方法,根据主机和监测站点硬件性能的特点自定制的通信协议,以保证通信的可靠性与有效性。论述了基于数据库的触发器技术完成对实际测量数据的维护与管理的实现方法。本系统已应用于污水流量监测等环保领域,经过长期的运行,可靠性高,使用灵活,安装方便,应用前景广阔。
On-line physical parameters are continuously monitored for the metropolitan water network and gas network and so on, and monitored data are transmitted to supervision center for data process, data analysis and data management through network. The primary functions of the system are expounded according to working specialty and requirement of primary computer system used monitoring all kinds of fields. Main operation and application method about AT commands are stated in transmitting data based on GSM network and the rational communication protocol is defined according to the characteristic of primary computer and monitor station hardware, which ensure reliability and validity of theirs communication. The maintenance and management of practical measuring data are discussed based on the flip-flop technology of database. The system is applied to many fields of environmental protection, and its high reliability, flexible application, convenient installation and wide used foreground are proved over a long period of time.
