Problems solved by technology
[0005] In view of this, the purpose of the present invention is to provide a solar cell array power adjustment device suitable for unattended stations in the field, which can solve the problem of the large output voltage range of the solar cell array caused by the complex geological environment in which the unattended field station is located. The output voltage of the battery array is lower than the load voltage, resulting in the problem that energy cannot be utilized

The invention discloses a solar cell array power adjusting device suitable for a field unattended station, and the control of the power adjusting device is divided into a no-load mode, a voltage reduction mode, a direct connection mode, and a voltage boosting mode according to the output voltage of a solar cell array and the voltage of a storage battery. Power generated by the solar cell array canbe fully utilized, buck-boost control is achieved, the limitation that the output voltage of an original solar cell array must be larger than the requirement of a storage battery is overcome, and therequirement that the output voltage range of the solar cell array is wide due to the complex geological environment of a field unattended station is met. According to the invention, the configurationof the solar cell array and the storage battery is more flexible, the universality is better, a power adjusting device of an original system can be directly replaced, and the cost is saved.
Description
technical field [0001] The invention belongs to the technical field of natural disaster prevention and forecasting, and in particular relates to a solar cell array power regulating device suitable for unattended stations in the field. Background technique [0002] my country is one of the countries most seriously affected by debris flow, and the country has an urgent need for monitoring and early warning of geological disasters. In addition, in the field of security monitoring of unattended border stations, safety monitoring of major projects such as dams and culverts, the demand for remote monitoring and early warning is also very strong. [0003] Most of these monitoring and early warning needs are located in unattended areas in the wild, and equipment maintenance personnel are not easy to reach. Therefore, the energy system powered by solar energy must be able to provide long-term, highly reliable uninterrupted energy under limited conditions to ensure the demand for moni...
