Photovoltaic power supply control device for camera monitoring

Abstract

The invention relates to a photovoltaic power control device for video surveillance. The device consists of a main circuit, a voltage and current detection circuit, a microcontroller and a communication circuit, wherein a first input end of the main circuit is connected with an output port of a photovoltaic battery; the output end of the main circuit is connected with the input end of the voltage and current detection circuit; the output end of the voltage and current detection circuit is connected with the input ends of the microcontroller and the communication circuit; the output ends of the microcontroller and the communication circuit are connected with a second input end of the main circuit; the main circuit charges the storage battery; the microcontroller and the communication circuit are respectively in two-way communication with a monitoring computer by virtue of a network camera and a wireless bridge. The invention further discloses a control method of the photovoltaic power control device for video surveillance. According to the photovoltaic power control device for video surveillance, direct current supply is directly performed, and inversion, rectification and voltage stabilization links with quite high power consumption are omitted, so that self consumption of the system is greatly reduced, and the power supply time is greatly improved under same photovoltaic and energy storage design capacity.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a photovoltaic power source control device for camera monitoring. Background technique [0002] Camera monitoring is an important part of the security system. It can transmit the image content of the monitored place to the monitoring center, so that the situation of the monitored place is clear at a glance; it can also record all or part of the image and sound for future monitoring of some The handling of incidents provides convenient conditions and important basis. The wireless monitoring system makes up for the shortcomings of the wired deployment of camera monitoring. It is a combination of monitoring technology and wireless network transmission technology, which can support cross-platform and cross-regional video intercommunication, and has become the mainstream of camera monitoring system development. [0003] The wireless camera monitoring system is mainly comp...
