[0002] As a special type of cultivation, greenhouses can achieve artificial control of key factors for crop growth such as indoor temperature and humidity and nutritional conditions, and effectively solve the contradiction between seasonal production restrictions and market supply of fruits, vegetables, flowers and other products under natural conditions. According to different climatic conditions and production needs, there are mainly plastic greenhouses, solar greenhouses, CNC greenhouses and other types of facilities. Plastic greenhouses have the characteristics of low construction cost and simple structure, but they cannot guarantee continuous production for plants that are not tolerant to low temperatures in winter. CNC greenhouses can effectively guarantee continuous production through heating methods such as natural gas and air conditioning, but it will greatly increase production costs. Solar greenhouses can also continue to produce fruits and vegetables in winter by adding physical measures such as insulation walls and insulation quilts. However, in case of low temperature weather and continuous poor light weather, solar greenhouses cannot guarantee the temperature in the greenhouse, and thus cannot guarantee the normal growth of fruits and vegetables.

[0006] The beneficial effect is that when the temperature control device of a solar greenhouse of the utility model is used, the solar energy is converted into electric energy by the photovoltaic device and stored in the electric storage device. At the same time, the windmill power generation device can also convert wind energy into electric energy and store it in the electric storage device, so that it can adapt to a variety of different weather conditions, and the electric energy can also be stored in the electric storage device, so that the water in the water reservoir can be heated in windless and low-temperature weather and continuous poor light weather, so that the water in the water reservoir is heated into steam and diffused to various positions in the greenhouse body, thereby performing heating and humidification operations in the greenhouse body. When the temperature control device of a solar greenhouse of the utility model is used, it can adapt to a variety of weather conditions, and it can also store electric energy, so that the temperature and humidity in the greenhouse body can still be controlled in windless and lightless weather.

[0007] Furthermore, a temperature sensor and a humidity sensor are also provided in the shed.

[0008] Beneficial effect: It is convenient to monitor the temperature and humidity in the greenhouse, so that the staff can adjust the temperature and humidity in the greenhouse, so that the temperature and humidity meet the conditions for the growth of fruits and vegetables.
