介绍了基于GPRS技术建立的环保在线检测系统,该系统提出了利用GPRS技术实现对分布在不同区域的排污点进行远程监控和管理。系统以宏电H7710系列GPRSDTU与西门子PLC(S7-224XPCN)作为数据采集、控制与通信的核心,文章给出了系统的硬件结构图,对系统的配置、工作原理、功能、实现和应用情况等进行了详细的阐述。通过实践结果表明,该系统实现了环保监察部门对排污点的及时管理,提高了工作效率。
This paper introduces a green online detection system based on GPRS technology. The system proposes the use of GPRS technology to remotely monitor and manage the discharge points distributed in different areas. The system takes the H7710 series GPRSDTU and Siemens PLC (S7-224XPCN) as the core of data acquisition, control and communication. The article gives the hardware structure of the system and the configuration, working principle, function, implementation and application of the system Carried out a detailed description. The results show that the system has realized the environmental supervision departments to timely management of sewage points, improve work efficiency.
