A solar outdoor power supply system

Abstract

The invention relates to the field of photovoltaic application and provides a solar outdoor power system. The solar outdoor power system has the advantages that a monitoring mode is more flexible and convenient, running state of an outdoor power source can be mastered anytime and anywhere, a preventive scheme can be made in advance to remind a user of taking preventive measures in advance, according to future weather conditions and charging conditions of the outdoor power source, and fewer emergencies occur.

Description

technical field [0001] The invention relates to the field of photovoltaic applications, in particular to a solar outdoor power supply system. Background technique [0002] The solar radiation energy received by the earth's surface every minute is as high as 80*10 12 A kilowatt is equivalent to 6 billion tons of standard coal. Since the supply of solar radiation can be said to be continuous, so solar energy can be said to be inexhaustible and inexhaustible. The use of solar energy to generate electricity will not cause environmental pollution. Using clean energy to replace traditional fossil energy is the best choice to maintain sustainable development. The development and utilization of solar energy has been valued by more and more countries. my country's photovoltaic equipment manufacturing The formation of a scale has provided a strong support for the development of the photovoltaic industry. [0003] The solar outdoor power supply uses solar energy for charging operation...

Problems solved by technology

[0003] The solar outdoor power supply uses solar energy for charging operation. Therefore, the charging operation of the solar outdoor power supply is easily affected by external factors. It is necessary for personnel to regularly detect, monitor and maintain the status of the solar outdoor power supply to ensure that the solar outdoor power supply is always In the normal working state, if the working state of the solar outdoor power supply cannot be monitored all the time, and the abnormality of the solar outdoor power supply cannot be detected in time, it is easy to cause damage to the solar outdoor power supply, and the abnormal power supply will affect the normal operation of the load equipment. It will cause economic losses, and more seriously, it will cause damage to the load equipment. However, the current monitoring methods of solar outdoor power supplies are too rigid, not flexible, and have low monitoring convenience. It is not conducive to timely discovery of abnormal faults and will increase the monitoring personnel work intensity

[0004] Among them, the solar outdoor power supply will be affected by the weather. When it is cloudy, heavy rain and other weather conditions, the solar radiation ability is weak, the solar outdoor power supply has a weak charging ability through solar charging, and the load consumes power. In this case, Under the circumstances, personnel are required to charge and replenish the external battery of the solar outdoor power supply. Through the operation of the external battery by personnel, it is impossible to judge whether the remaining power of the solar outdoor power supply is in the situation of requiring an external battery. If the remaining power of the solar outdoor power supply is still large, directly Connecting an external battery will cause the resources of the solar outdoor power supply to not be fully utilized. If the external battery is connected when the remaining power of the solar outdoor power supply is low, it is easy to make a mistake in judging that the power is too low. Charging when the power is too low will cause Forming damage to the solar outdoor power supply will reduce the service life of the solar outdoor power supply, and will also cause intermittent power outages, which will have a great impact on the normal operation of the load and cause economic losses; It is to set the remaining power detection circuit and the automatic external battery switching circuit on the solar outdoor power supply. When the remaining power detection circuit of the solar outdoor power supply detects that the remaining power of the solar outdoor power supply is lower than a certain point, it will pass the switching circuit. Charging the external battery of the outdoor power supply can make an accurate judgment on the remaining power of the solar outdoor power supply, and can switch the external battery at the best time to ensure the life of the solar outdoor power supply and the normal operation of the load equipment. The way of automatic switching through the combination of the detection circuit and the switching circuit is an emergency measure to be taken in cloudy, heavy rain and other weather conditions, that is, the feeling of "scrambling" to take measures after the situation occurs. If there is a problem, the power of the solar outdoor power supply will be insufficient, and the load will not work normally, which will cause great economic losses, and it will be difficult to carry out maintenance work under severe conditions such as heavy rain.
