Description

technical field [0001] The invention relates to the technical field of data detection, in particular to a testing device and system for an environmental protection data acquisition instrument. Background technique [0002] With the country's emphasis on environmental protection, the research and development of a multi-functional, full-coverage environmental monitoring system is imperative. As an intermediate device in the environmental protection monitoring system, the environmental protection data acquisition instrument not only has the function of collecting monitoring instrument data (compatible with multiple communication protocols), but also has the ability to transmit data to the upper system, and can also control the detection instrument and external equipment. And can set the monitoring instrument and external equipment. However, in the testing process of the environmental protection data acquisition instrument, the method of manual testing is still adopted. Due to ...
