Pollutant discharge monitoring and control equipment,working at pollution site, must collect pollutant discharge data through connetcted varioys sensors and online analytic instruments and upload data to the monitoring center.The interface on equipment is many kinds of and multi amount. Performance test of this kind of equipment could be very miscellaneous because of the large variety and quantity of interface. The specially designed "Integrative Test Platform for Environmental Protection Monitoring and Control Equipment" could not only provide multiple accurate analog signal,switch signal and digital signal, but also communicate with EUT via Ethernet and GPRS. Using HJ/T-212 "Standard for data communication of environment monitoring system", the platform can load the information sent by the EUT and complete auto analysis to the testing result,which increases the accuracy and efficiency of detection work significantly.%工作在排污现场的污染源排放监控设备需要连接各种传感器和在线分析仪器来采集数据,并将数据传输到上级监控中心,其接口的种类和数量非常多,这使性能测试工作十分繁琐.专门设计的"环保监控设备综合测试平台",能够提供多路精准的模拟量、开关量、数字量信号源,并可与被测设备通过以太网和GPRS方式进行通信,巧妙地利用HJ/T-212协议读取被测设备发出的上传信息,完成对检测结果的自动判断,大大提高了测试工作的准确性和效率.
