Description

Technical Field

[0001] This utility model relates to the field of vegetable greenhouse technology, specifically a smart vegetable greenhouse. Background Technology

[0002] In modern agricultural production, vegetable greenhouses have become core facilities for ensuring a stable supply of vegetables and improving planting efficiency due to their advantages in creating a suitable growing environment for crops and resisting the interference of harsh weather. With the upgrading of planting needs, greenhouses are also gradually developing towards automation and multi-functionality, and various greenhouse structures with specific convenient functions are constantly emerging.

[0003] For example, CN214338935U discloses a multifunctional vegetable greenhouse, the core structure of which includes a greenhouse body (with a plastic film on the outside), a track on the outside of the body (with a protective shell and spring), a slider sliding on the track, and a winding box on the top of the body (with a built-in active rotating shaft, a passive rotating shaft, and a corresponding winding roller). A heat-insulating felt fixed to the outside of the winding roller is connected to the slider. Together with a motor, active gear, passive gear, and other components, the greenhouse can automatically retract and extend the heat-insulating felt, while also clearing snow from the greenhouse roof, significantly reducing manual labor and effectively improving the efficiency of greenhouse management.

[0004] Despite the significant advantages mentioned above, this multi-functional vegetable greenhouse still has key technological shortcomings: on the one hand, it lacks the ability to monitor core environmental parameters such as temperature and humidity inside the greenhouse in real time, making it impossible to capture changes in the greenhouse environment in a timely and accurate manner; on the other hand, due to the lack of real-time monitoring data, the greenhouse cannot intelligently adjust parameters according to fluctuations in the greenhouse environment.

The monitoring component 2 includes a temperature sensor 201, a humidity sensor 202, a carbon dioxide sensor 203 installed at the top inside the greenhouse body 1, and a soil moisture sensor 204 inserted into the soil inside the greenhouse. The execution component 4 includes a water supply pipe 401 installed in the upper space inside the greenhouse body 1 and fixedly connected at both ends to the side walls of the greenhouse body 1. A row of nozzles 402 is fixedly connected to the lower wall of the water supply pipe 401. One end of the water supply pipe 401 passes through the side wall of the greenhouse body 1 and is connected to a main pipe 403. A solenoid valve 404 is installed on the main pipe 403. The execution component 4 also includes a ventilation mechanism 405 installed on the rear wall of the greenhouse body 1 and a carbon dioxide generator 406 placed on the ground of the greenhouse body 1. Both the ventilation mechanism 405 and the carbon dioxide generator 406 are electrically connected to the controller 3.

[0031] The ventilation mechanism 405 includes a mounting frame 4051 fixedly installed on the rear wall of the shed 1. An axial fan 4052 is installed inside the mounting frame 4051. A limiting frame 4053 is fixedly connected to one end of the mounting frame 4051 facing the inside of the shed 1. Limiting grooves 4054 are opened on the inner walls of both sides of the limiting frame 4053. A folding sealing curtain 4055 is installed inside the limiting frame 4053. The two ends of the folding sealing curtain 4055 are slidably connected to the corresponding limiting grooves 4054. The upper end of the folding sealing curtain 4055 is fixedly connected to the upper inner wall of the limiting frame 4053.

[0032] The ventilation mechanism 405 also includes a fixing strip 4056 fixedly connected to the lower end of the folding sealing curtain 4055. The fixing strip 4056 is fixedly connected to a connecting plate 4057. The connecting plate 4057 has an internal thread hole and a lead screw 4058 is threaded through the internal thread hole. The upper end of the lead screw 4058 is rotatably connected to a limiting sleeve a4059 fixed to the upper end of the limiting frame 4053. The lower end of the lead screw 4058 is rotatably connected to a limiting sleeve b4060 fixed to the lower end of the limiting frame 4053. The lower end of the lead screw 4058 is fixedly connected to the output shaft of a drive motor 4061 installed on the side of the limiting sleeve b4060.

[0033] The data acquisition module 301 is used to acquire data monitored by the temperature sensor 201, humidity sensor 202, carbon dioxide sensor 203 and soil moisture sensor 204.

[0034] The intelligent control module 302 is used to control the start and stop of the solenoid valve 404, carbon dioxide generator 406, axial fan 4052 and drive motor 4061 based on the data collected by the data acquisition module 301.

[0035] The wireless transmission module 303 is used to communicate with the mobile terminal to transmit monitoring information to the mobile terminal and receive control commands.

[0036] Working principle: First, the monitoring components 2 inside the greenhouse 1 collect environmental and soil data in real time: the temperature sensor 201, humidity sensor 202, and carbon dioxide sensor 203 installed on the top of the greenhouse capture air temperature, air humidity, and carbon dioxide concentration information, respectively, while the soil moisture sensor 204 inserted into the soil obtains soil moisture content data. This monitoring data is transmitted in real time to the data acquisition module 301 of the controller 3.

[0037] Next, the intelligent control module 302 of controller 3 analyzes the collected data and compares it with preset threshold values ​​for suitable vegetable growth parameters: if the data from soil moisture sensor 204 is below the threshold, it indicates that the soil is short of water, and the intelligent control module 302 will trigger the opening of the solenoid valve 404 on the main pipe 403 in the execution component 4, and the water in the water supply pipe 401 will be evenly sprayed onto the soil through the nozzle 402 on the lower wall to replenish the water; if the data from carbon dioxide sensor 203 is below the threshold, the intelligent control module 302 will start the carbon dioxide generator 406 to supply water to the greenhouse. Carbon dioxide is released inside to meet the needs of vegetable photosynthesis. If the data from temperature sensor 201 or humidity sensor 202 exceeds the threshold, intelligent control module 302 first controls drive motor 4061 to run, which drives lead screw 4058 to rotate. This causes connecting plate 4057, which is threaded to lead screw 4058, to drive fixing strip 4056 and folding sealing curtain 4055 to retract upward along limiting groove 4054, opening the ventilation channel. Then, axial flow fan 4052 in mounting frame 4051 is started to accelerate air circulation inside and outside the greenhouse and adjust temperature and humidity to a suitable range.

[0038] Meanwhile, the wireless transmission module 303 of the controller 3 will transmit real-time data such as temperature, humidity, carbon dioxide concentration and soil moisture collected by the monitoring component 2 to the user's mobile terminal, so that the user can remotely monitor the greenhouse environment in real time. If the user needs to intervene manually, he / she can also send control commands through the mobile terminal, which will be transmitted to the intelligent control module 302 through the wireless transmission module 303, and drive the corresponding execution components to perform actions, so as to realize the combination of remote manual control and intelligent automatic control.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
