The system is advantaged in that the internal function modules of the visual monitoring and photographing system are graded according to importance and energy consumption, charging strategy management is carried out in combination with the residual electric quantity and meteorological data, and the working duration of core functions of the monitoring and photographing system is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of visual monitoring and shooting of power transmission lines, in particular to a power supply meteorological control system and method for visual monitoring and shooting of overhead lines. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The power supply system of the existing transmission line visual monitoring system uses solar panels to obtain light energy, and charges the power supply through the solar charging management circuit to store electric energy. [0004] Due to the different light time and light intensity in different geographical locations, the temperature in different seasons in the same location is different. Therefore, it is very important for the power management of the transmission line visual monitoring system to consider the impact of meteorological ...

Problems solved by technology

The battery voltage is relatively stable. For example, the working voltage of a 6.4V lithium iron phosphate battery is 5.5V to 7.2V, while the working voltage range of a super capacitor is wide, up to 0 to 10.8V. In the existing hybrid power supply of batteries and super capacitors, The battery and the supercapacitor are connected in parallel through a diode, and supply power to the subsequent load according to the voltage level. When the discharge voltage of the supercapacitor reaches or is lower than the battery voltage, the system takes power from the battery. In this way, the remaining power of the supercapacitor cannot be released, and the supercapacitor is not fully utilized. Capacitor capacity
