A: In the greenhouse, if the strawberry is in the wind, the film will bulge with the wind and fall down. If it is not managed in time, the film will be blown, causing the strawberry in the shed to suffer from freezing damage. Management measures: Block all the vents to prevent the wind from blowing into the shed to damage the strawberry plants and destroy the shed film. Pull the film line tightly and, if necessary, put a part of the grass to press the film. If there is a strong wind at night, it is necessary to press the grasshopper firmly. It is best to use a woven bag to hold a half bag of soil on a part of the grasshopper to prevent the wind from scraping off the grasshopper.

There is no doubt that solar monitoring has brought great convenience to people. It saves a lot of manpower and material resources without having to stick to the post for 24 hours as before. Not to mention that the current surveillance cameras have the function of motion detection. As long as someone enters a certain range, it will automatically alarm and capture the scene. What is the function of the solar monitoring system?

1. Solar panel: The solar panel is an important part of the mobile phone software of the solar power generation system, and also a part of the practical value of the mobile phone software of the solar power generation system. Its function is to convert the professional ability of radioactive substances in natural light into electric energy, or send them to storage batteries, or promote load work.
2. Solar controller: The solar controller is used to control the operation of mobile phone software in all systems, and has the functions of overcharge protection and overcharge maintenance for the battery. In areas with large temperature difference, the qualified controller shall also have the function of temperature compensation. In the mobile phone software of the solar road lamp system, there must be light control switch and time control solar road lamp operation.
3. Battery: generally valve controlled maintenance free lead-acid battery. In the mobile phone software of small and medium-sized systems, in cold weather areas, a solar gel battery needs to be configured, which can be used at low temperatures, with high efficiency and is not vulnerable to major damage. Its function is to store the electric energy of the solar panel when the sun shines, and then release it under certain conditions.
4. Variable frequency power supply: split wave type and sine wave type. In order to provide power for 220VAC electrical products, it is necessary to convert the DC stabilized voltage power supply in the solar power generation system software into AC circuit energy, so DC AC variable frequency power supply is required.
