Description

technical field [0001] The present invention relates to the fields of solar energy application and wireless sensor network, and more specifically, relates to a solar azimuth tracking power supply device and a control method thereof. Background technique [0002] With the gradual improvement of my country's power transmission system, the number of power towers is also increasing. Most of the power poles and towers are built in the wild where there are few people and inconvenient transportation. Power towers are very important to power transmission lines, so it is necessary to monitor the safety status of the towers. Due to the influence of geographical environment and other factors, the efficiency of manual monitoring of the safety status of towers is low, and the introduction of wireless monitoring network for tower tilt is an excellent choice. [0003] Maintaining the normal operation of wireless sensor network nodes requires power supply, and the use of solar power panel...
