Screen cabinet microenvironment safety control method and system

The invention discloses a screen cabinet microenvironment safety management and control method and system, and the system comprises a monitoring assembly which comprises a housing, and a sensor, a magnet, a first conductive block and a monitoring circuit which are disposed in the housing; the mounting assembly is arranged on the screen cabinet and comprises a response circuit and a response part; according to the invention, historical data are collected to establish a cable life prediction model, current data are sensed and monitored by using a CT electricity taking technology, the surface temperature of the cable is monitored in real time by using a patch temperature sensor to carry out multi-point deployment, and the insulation state of the cable is detected by using a spectrum analysis device, so that whether an arc light phenomenon occurs can be judged; real-time monitoring and data recording of the working microenvironment in the screen cabinet are achieved, the cable working state grade is input into th
