Monitoring camera power supply system based on solar energy

Abstract

The invention provides a monitoring camera power supply system based on solar energy. The monitoring camera power supply system comprises a solar cell panel, a lithium battery management module, a lithium battery pack, a direct-current boosting module, a power grid power supply module, a solar switching control module, a lithium battery switching control module and a power grid switching control module. The input end of the lithium battery management module is connected to the output end of the power grid power supply module, the output end of the lithium battery management module is connectedwith the positive electrode of the lithium battery pack, the positive electrode of the lithium battery pack is connected with the input end of the lithium battery switching control module, and the output end of the lithium battery switching control module is connected to the input end of the direct-current boosting module. The first detection input end of the lithium battery switching control module is connected to the output end of the power grid power supply module, and the second detection input end is connected to the output end of the solar switching control module; the power grid switching control module converts commercial power into direct current, the output end of the power grid switching control module is connected with the input end of the power grid switching control module,and the output end of the power grid switching control module supplies power to the camera.

Description

technical field [0001] The invention relates to a power supply system, in particular to a solar energy-based surveillance camera power supply system. Background technique [0002] As a kind of image acquisition equipment, the camera is widely used in the current production and life to provide guarantee for the safety of people's production and life, and provide data support for security. Therefore, the working stability of the camera is extremely important, and the working stability of the camera Performance depends on two aspects: on the one hand, the working stability of the camera itself, and on the other hand, the power supply stability of the camera; The stability mainly depends on the stability of the power supply. In the prior art, the power supply of the camera generally adopts the mains power supply. The joint power supply method, however, the existing circuit structure is complicated, and the switching response between solar energy and mains power is slow, which c...

[0002] As a kind of image acquisition equipment, the camera is widely used in the current production and life to provide guarantee for the safety of people's production and life, and provide data support for security. Therefore, the working stability of the camera is extremely important, and the working stability of the camera Performance depends on two aspects: on the one hand, the working stability of the camera itself, and on the other hand, the power supply stability of the camera; The stability mainly depends on the stability of the power supply. In the prior art, the power supply of the camera generally adopts the mains power supply. The way of joint power supply, however, the existing circuit structure is complex, and the switching response between solar energy and mains power is slow, resulting in a long interruption of the power supply of the camera, which is not conducive to the collection of security data
