The embodiment has three cores, namely accurate measurement; secondly, wireless transmission is carried out; and thirdly, collecting, monitoring, processing and analyzing the measurement result.
The accurate measurement is that a high-precision test transmitter is adopted in the system, so that the test deviation is reduced. Compared with the similar equipment, the Rosmont measuring instrument adopted by the project has excellent measuring performance and safety. Meanwhile, the selected measuring instrument has small size and large measuring range span, and can adapt to various working conditions by using a small amount of instruments. The measuring instrument is placed in a special box body, and can be quickly carried to a measuring site for relevant tests.
In order to reduce the limitation of the working environment on data transmission, the data acquisition is carried out in a wireless transmission mode in the system.
