摘要
环境监控系统中各分散监控点的数据传输问题,一直是建立环境监控系统的难点。以往采用有线或无线电台通信方式组网,常常存在费用高、覆盖范围小和可靠性低的问题。设计了一种新型环境监控系统,该系统以GSM中短消息业务SMS为终端监控站的通信方式,上位机监控站采用因特网通信,因特网与GSM网络通过GSM网关连接,具有组网方便、覆盖范围大、经济、可靠、易于推广等特点。在实际应用中,系统运行稳定、测量准确、监控得力,大大提高了工作效率、节省了人力物力。
In environmental monitoring system, the data transmission among each scattered monitoring point is always a difficult problem in establishing the monitoring system. In the past, adopting wired or radio station to organize network had the shortcomings of high cost, incomprehensive coverage and low reliability. Now, the new-type environmental monitoring system is designed, in which, the SMS of GSM is used as its communication mode of terminal monitoring station. Internet communication is adopted in monitoring station of host computer. Interact was con- nected with GSM network by GSM gateway. This system has the characteristics of convenience, broad range; reliability, economical; easy to popularize, etc. In practical application, the system is in stable operation, accurate measurement, powerful monitoring. It enhances the operating efficiency and saves the manpower and materials.
