The monitoring unit is powered by a primary 220V power supply of the signal lighting unit and communicates with centralized monitoring in the mechanical room by means of a power carrier technology. In order to ensure the normal operation of other devices on the power line, the monitoring unit itself adopts a low power consumption design, and collects the current of itself in real time to report to the user, as shown in the current monitoring circuit in fig. 3. The design principle of the circuit is as follows: adopt monitoring transformer to gather monitoring unit's operating current, the current value that will keep apart output sends current acquisition module to and handles, through the conversion calculation, acquires the current value of connecting the monitoring unit power supply line of gathering in real time, uploads and gives the user and provides unusual circuit alarming function simultaneously: the system comprises alarm information such as overcurrent alarm and mixed alarm of a working line, and improves the usability of products.
