[0014] Compared with the prior art, the present invention has the following beneficial effects: First, the present invention uses wall panels and door panels as basic supports, and uses the ceiling and two side sheds at the top of the pad as the basic frame, and uses a protective film as insulation and rain protection for the air vents in the frame, and the left and right sides of the protective film are respectively immersed in the interior of the ceiling or side shed and inserted into the slots on the outside of the protective shell. When the protective film needs to be retracted, the motor is started to rotate the rotating shaft, causing the rotating shaft to rotate to the right, so that the protective film fixed on the rotating shaft is rolled up along the rotation of the rotating shaft and covers the surface of the rotating shaft, and the protective film is pulled out from the slot of the protective shell used for limiting. At the same time, when the protective film is rolled toward the center of the rotating shaft, the stretching rods fixed at both ends of the protective film are pulled out, and the spring extends its total length along with the tension. The top rod diameter of the stretching rod is smaller than the limit of the slot, and can protrude from the slot and follow the protective film to stick to the outside of the rotating shaft. This step is used to prevent the protective film from being moved on both sides after being rolled into the rotating shaft, either upward or downward, making it inconvenient to realign the position of the slot when released, and it is a hard structure itself. The stretching rod of the structure can fix the two sides of the protective film to always be aligned parallel to the position of the slot, and a spring is installed inside the coil block to pull the coil rope towards the inside of the coil block. When the protective film is retracted, the coil ropes on both sides will also be pulled out from the inside of the coil block along with the two sides of the protective film, and the force of pulling the protective film in the opposite direction is always maintained, which can ensure that when the protective film is rolled up by the rotating shaft, the protective film is always kept in a taut planar state due to the simultaneous tension on both sides, which is convenient for rolling up and preventing wrinkles. When the protective film needs to be released, the motor is started to rotate the rotating shaft to the left, and the protective film rolled up and covering the surface of the rotating shaft is released. While maintaining the plane, the protective film is reinserted into the interior of the protective shell from the slot under the guidance of the stretching rod by pulling the coil ropes on both sides, so that the protective film is redeployed in the air vent. The protective film can be automatically adjusted, manual intervention is reduced, ventilation efficiency and thermal insulation response speed are improved, space occupancy is reduced, and the problems of low efficiency and high labor intensity in manual adjustment of the protective film are solved.

[0015] Second, the present invention fixes the structure at an upper position inside the greenhouse through the support block of the water storage mechanism, and uses an exhaust fan to extract the air in the greenhouse, wherein the exhaust head is a conical structure, which can expand the working range of the exhaust, and the extracted gas is uniformly gathered into the exhaust fan through the exhaust pipe and injected into the condenser through the air supply pipe, and the water vapor in the gas is condensed into liquid by the condenser, and the gas is discharged from the top through the exhaust port and discharged to the outside through the air vents on the ceiling. When ventilation is needed, the ventilation mechanism can be assisted to discharge the indoor gas to the outside, and the outdoor air can be quickly drawn into the room by the air pressure generated by the exhaust. When ventilation is not needed, the humid environment in the greenhouse can also be dehumidified, thereby improving the humidity environment of the greenhouse, reducing the moisture content of the indoor air, and avoiding the accumulation of water vapor, which condenses on the top of the greenhouse and drips onto instruments or staff.

[0016] Third, the present invention ensures the thermal insulation performance of the greenhouse itself through the insulation board, uses the control panel as the basic control center, and is responsible for receiving and sending signals through the wireless port, allowing staff to remotely control the control panel, and the control panel can manually turn on and off the sunlight sensor and liquid sensor, increasing fault tolerance, allowing staff to consider whether to turn on automation according to actual conditions, and react to light through the sunlight sensor, and the sunlight sensor fixed on the top facing the sky is also difficult to be activated by the light below. When the sun is bright, the indoor light of the greenhouse is good, the temperature gradually rises, and the evaporation rate of moisture in the soil becomes faster, making the indoor environment gradually humid. At this time, the sunlight sensor is triggered by the brighter light and the exhaust fan is automatically turned on. The gradually humid environment in the room is automatically dehumidified through the water storage mechanism. The liquid sensor is fixed on the top of the side shed, facing two opposite directions. When it rains, water falls on any one of the two liquid sensors. The liquid sensor receives rainwater and is activated, generating a signal to automatically turn on the motor, and automatically releases the protective film through the ventilation mechanism, allowing the protective film to be quickly deployed in the air vent. , preventing rain and low temperatures from entering the greenhouse, and being able to automatically and quickly respond to weather changes, achieving automated ventilation and insulation, and reducing operation and maintenance costs. Among them, the embedded microcontroller uses the STM32 model with an integrated Wi-Fi / 4G module, which is responsible for data acquisition and equipment control, and connects to the National Meteorological Administration API to obtain weather data for the next 72 hours, including temperature, humidity, rainfall probability, wind speed, and light intensity. According to the temperature and humidity data, the motor speed is automatically controlled and the opening and closing angle of the protective film is adjusted. The air vents are opened when the temperature is high and closed when the temperature is low. When the probability of rainfall exceeds 50%, the exhaust fan and the gas pipe are turned off to prevent rainwater from backflowing. When the light intensity is lower than the set value, the condenser auxiliary heating is started to maintain the greenhouse temperature. When the wind speed exceeds the set threshold, the protective film is automatically rolled up into the protective shell to avoid damage. When an extreme weather warning is received, all equipment is turned off to close the greenhouse to avoid weather impact as much as possible. The network module can adjust the status of the greenhouse in advance according to the forecast, so that it can be prepared in advance before the corresponding weather arrives, further improving the speed of responding to weather changes.

Among them, the embedded microcontroller uses the STM32 model, integrated with Wi-Fi / 4G modules, responsible for data acquisition and equipment control, and connects to the National Meteorological Administration API to obtain weather data for the next 72 hours, including temperature, humidity, rainfall probability, wind speed, and light intensity. According to the temperature and humidity data, the speed of the motor 106 is automatically controlled, and the opening and closing angle of the protective film 108 is adjusted. The ventilation opening is opened when the temperature is high and closed when the temperature is low. When the probability of rainfall exceeds 50%, the exhaust fan 203 is turned off and the gas pipe 207 is closed to prevent rainwater from flowing back. When the light intensity is lower than the set value, the condenser 208 is started for auxiliary heating to maintain the temperature of the greenhouse. When the wind speed exceeds the set threshold, the protective film 108 is automatically rolled up into the protective shell 109 to avoid damage. When an extreme weather warning is obtained, all equipment is turned off to make the greenhouse enter a closed state to avoid weather influences as much as possible. The network module can adjust the state of the greenhouse according to the forecast in advance, so that preparations can be made before the corresponding weather arrives, further improving the speed of responding to weather changes.
