[0002] With the development of society, people's safety awareness is getting deeper and deeper, and the monitoring system is widely used as an important tool for safety prevention. At present, the monitoring system mainly includes centralized power supply and distributed power supply, and the power supply of distributed power supply does not appear as an independent component. In the system, it is distributed in different parts of the system, so that the monitoring is independent, and it will not affect the monitoring of other parts due to the power failure of one part of the power supply. However, this power supply method increases the difficulty of power supply management and circuit detection; centralized power supply is The power supply appears in the system as an independent component, which makes the power supply management more convenient, and can clearly carry out power supply management and system detection, but this power supply mode makes the power supply not independent, and the work of the monitoring system will be affected after the power supply is cut off. Safety precautions cause some trouble

Embodiment Construction
[0011] combine figure 1 , the control method of the power supply of the monitoring system mainly adopts the form of centralized power supply, and uses the external power supply to supply power to the monitoring system for a long time. The control method of the power supply is as follows:
[0012] Step 1, connect the AC power supply to the main power control cabinet, the main power control cabinet supplies power to the regional power control cabinets, and the regional power control cabinets provide split power supply for each monitoring device;
[0013] Step 2, connect the main power control cabinet to the single-chip controller, the single-chip controller is connected to the storage battery, and the storage battery is connected to the photovoltaic module through the rectifier;
[0014] Step 3. When the AC power supplies power to the main power control cabinet, the single-chip controller in the main power control cabinet receives the pulse signal sent by the AC power supply and...

The invention discloses a monitoring system power supply control method. A centralized power supply form is mainly adopted, an AC power supply and a battery are connected onto a main power control cabinet, a photovoltaic module provides power for the battery via a rectifier, a single chip microcomputer controller inside the main power control cabinet receives pulse signals sent by the AC power supply or pulse signals sent by the battery, power provided to the main power control cabinet by the AC power supply or the battery is judged, the main power control cabinet provides power for power control cabinets in sub regions after power supply, and the power control cabinets in sub regions carry out shunt power supply for monitoring devices. The centralized power supply mode is used for providing power for the monitoring system, power supply management is quick and convenient, the system detection is convenient, the battery provides power for the main power control cabinet after the AC power supply is cutoff, power supply of the monitoring system has certain independence, and safety precaution of people is not troubled.
