Strong and weak electricity separation design method and power adapter for power line network camera

Abstract

The invention relates to the field of power line network cameras, in particular to a strong and weak electricity separation design method and a power adapter for implementing the method for a power line network camera. A device for implementing the method comprises a camera end and an external power adapter end, the external power adapter end converts strong electricity to weak electricity and outputs the weak electricity to the camera end, and signals of data acquired by the camera end are transmitted to the external power adapter end through a power line network communication module and coupled to a mains supply line. According to the strong and weak electricity separation design method and the power adapter for implementing the method for the power line network camera, the external power supply is utilized for converting the strong electricity to the weak electricity to supply power for the power line network camera, prior built-in parts of a power line network camera switching power supply and the like are externally installed, so that the size of the camera can be substantially reduced, and due to the fact that all currents of the camera end are weak electricity, the condition that an electric shock happens to an operator due to the leakage of electricity of a machine during the usage and maintenance is avoided, and the safe working of a product is guaranteed.

Description

technical field [0001] The invention relates to the field of power line network cameras, in particular to a design method for separating strong and weak electricity of a power line network camera and a power adapter for realizing the method. Background technique [0002] existing. Because the power line network camera needs to transmit the signal through the power line, so if figure 1 As shown, the switching power supply, power line communication module and network camera are usually integrated, resulting in relatively large volume of existing network cameras; moreover, because many network cameras are located outdoors in many occasions, such as roads, docks, factory areas Monitoring at other locations, introducing 220V strong electricity into the network camera will easily cause safety hazards such as electric shock or leakage during use or maintenance. Contents of the invention [0003] The object of the present invention is to provide a design method for separating st...
