Description

Technical Field

[0001] The present invention relates to the technical field of agricultural Internet of Things, and in particular to an agricultural planting intelligent management system based on the Internet of Things. Background Art

[0002] The Internet of Things uses sensors, radio frequency identification technology, positioning technology, etc. to collect any objects or processes that need to be monitored and interacted in real time, and collects various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, etc. Through various possible network access, it realizes ubiquitous connection between objects and objects, objects and people, and realizes intelligent perception and management of processes;

[0003] By obtaining real-time data of farmland environment through real-time environmental monitoring, judging the growth of crops based on the data and taking effective measures in a timely manner, efficient production management can be achieved. In the agricultural production process, multiple natural factors such as temperature, humidity, light intensity, CO2 concentration, water, and other nutrients jointly affect the growth of crops. The management method of traditional agriculture is far from meeting the standards of refined management and can only be regarded as extensive management. Under this management method, it is impossible to meet the accuracy requirements by managing the above environmental parameters through human perception. Some existing intelligent management equipment often interferes with each other during monitoring and adjustment, resulting in many unnecessary multiple adjustments, which leads to low regulation efficiency and greatly reduced regulation effect. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that planting management in the prior art is not timely and sufficient, and to propose an agricultural planting intelligent management system based on the Internet of Things.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: an intelligent management system for agricultural planting based on the Internet of Things, comprising a management box and a pre-buried box, a placing table being fixed at the bottom of the management box, a temperature control chamber, a humidity control chamber and a concentration control chamber being provided inside the management box, a temperature control mechanism, a humidity control mechanism and a concentration control mechanism being provided in the temperature control chamber, the humidity control chamber and the concentration control chamber respectively, a diffusion box being fixed on the outer wall of the management box, an induced draft fan being installed inside the diffusion box, an exhaust pipe being installed at the bottom of the diffusion box, and a plurality of air injection pipes being installed at the top of the diffusion box.

[0006] In the above-mentioned IoT-based intelligent agricultural planting management system, the temperature control mechanism includes an upper guide plate and a lower guide plate fixed inside the temperature control chamber, and the upper guide plate and the lower guide plate are jointly fixed with multiple temperature regulating plates, and a heat transfer rod is installed at the upper end of the upper guide plate.

[0007] In the above-mentioned intelligent agricultural planting management system based on the Internet of Things, a first fan is installed inside the temperature control chamber, a first air inlet pipe is installed at the air inlet of the first fan, a first air outlet pipe is installed through the side wall of the temperature control chamber, and the temperature regulating plate is a semiconductor refrigeration plate.

[0008] In the above-mentioned intelligent management system for agricultural planting based on the Internet of Things, the humidity control mechanism includes a circulating water pump installed inside the humidity control chamber, the water inlet of the circulating water pump is installed with a suction pipe, and the water outlet of the circulating water pump is installed with a return pipe. The suction pipe and the return pipe are both connected to the embedded box, and the return pipe passes through the temperature control chamber. The side walls of the suction pipe and the return pipe are respectively installed with a circulating water inlet pipe and a circulating water outlet pipe, and a water supply pipe is installed at the upper end of the embedded box.

[0009] In the above-mentioned intelligent management system for agricultural planting based on the Internet of Things, a humidifying water pump is installed inside the humidity control chamber, and a humidifying water pipe is installed at the water outlet of the humidifying water pump.

[0010] In the above-mentioned intelligent management system for agricultural planting based on the Internet of Things, a humidification box is installed on the outer wall of the management box, the humidification water pipe is connected to the humidification box, and a plurality of water spray pipes are installed on the upper end of the humidification box.

[0011] In the above-mentioned intelligent management system for agricultural planting based on the Internet of Things, the concentration control mechanism includes a partition fixed inside the concentration control chamber, an absorption box is installed on the upper end of the partition, absorption particles are placed inside the absorption box, the lower half of the concentration control chamber is filled with absorption liquid, a second fan is installed on the inner wall of the concentration control chamber, a second air inlet pipe is installed at the air inlet of the second fan, a transfer pipe and a second air outlet pipe are installed through the upper end of the partition, and the upper port of the second air outlet pipe passes through the management box and is connected to the outside.

[0012] In the above-mentioned intelligent management system for agricultural planting based on the Internet of Things, a gas storage tank is installed on the top of the management box, and a plurality of gas filling pipes are installed through the side wall of the gas storage tank.

[0013] In the above-mentioned IoT-based intelligent agricultural planting management system, the absorption particles are sodium hydroxide particles, the absorption liquid is sodium hydroxide solution, the absorption box is a hollow structure, the lower port of the transfer pipe is located below the liquid level of the absorption liquid, and the lower port of the second air outlet pipe is located above the liquid level of the absorption liquid.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The temperature can be effectively controlled by controlling the power supply direction, and the temperature control is not carried out by exchanging air with the outside of the greenhouse, so the air humidity and carbon dioxide concentration inside the greenhouse will not change, thus completing the control of a single variable, and the control is accurate and effective;

[0016] 2. When the air in the greenhouse is dry, the humidification water pump transfers the water in the humidity control chamber to the humidification box, and then sprays it out through the water spray pipe, thereby achieving effective humidification over a large range. The induced draft fan inside the diffusion box works, and the air flow is sprayed upward from the bottom of the management box, so that the water vapor diffuses quickly, thereby achieving comprehensive humidification.

[0017] 3. The water flow inside the humidity control chamber can self-circulate and pass through the temperature control chamber, so that the water flow temperature inside the humidity control chamber can be controlled, thereby reducing the impact on the ambient temperature during the subsequent spraying and humidification process and avoiding repeated regulation;

[0018] 4. During the airflow transfer process, carbon dioxide is first basically absorbed and then fully absorbed, thereby completing effective carbon dioxide absorption processing. In addition, the carbon dioxide replenishment and absorption process are not exchanged with the external air. Therefore, the impact on the temperature and humidity inside the greenhouse is very small, which can reduce the difficulty of regulation and control, and will not impact the agricultural products in the greenhouse;

[0019] 5. The embedded box is buried underground and filled with water. Since the underground temperature is relatively stable, the temperature of the water stored in the embedded box is maintained at a constant temperature. The excess heat generated by the thermostat or when it needs to absorb heat can be exchanged with the circulating water flow, so that the thermostat can operate effectively for a long time.

DETAILED DESCRIPTION

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0029] Example

[0030] Reference Figure 1-7 , an intelligent agricultural planting management system based on the Internet of Things, includes a management box 1 and a pre-buried box 2, a placing table 3 is fixed at the bottom of the management box 1, a temperature control chamber 4, a humidity control chamber 5 and a concentration control chamber 6 are opened inside the management box 1, and a temperature control mechanism, a humidity control mechanism and a concentration control mechanism are respectively arranged in the temperature control chamber 4, the humidity control chamber 5 and the concentration control chamber 6. A plurality of groups of sensors are arranged outside the management box 1 to detect the temperature and humidity of the environment and the carbon dioxide concentration, and the concentration information can also be provided by an external device. A diffusion box 24 is fixed on the outer wall of the management box 1, an induced draft fan is installed inside the diffusion box 24, an exhaust pipe 25 is installed at the bottom of the diffusion box 24, and a plurality of jet pipes 26 are installed on the top of the diffusion box 24.

[0031] The temperature control mechanism includes an upper guide plate 7 and a lower guide plate 8 fixed inside the temperature control chamber 4. The upper guide plate 7 and the lower guide plate 8 are jointly fixed with a plurality of temperature regulating plates 9. A heat transfer rod 10 is installed at the upper end of the upper guide plate 7. By arranging the heat transfer rod 10, more contact heat transfer can be carried out when the airflow is transferred, thereby making the temperature adjustment process faster.

[0032] A first fan 11 is installed inside the temperature control chamber 4, and a first air inlet pipe 12 is installed at the air inlet of the first fan 11. A first air outlet pipe 13 is installed through the side wall of the temperature control chamber 4. The thermostatic plate 9 is a semiconductor refrigeration plate. After power is turned on, the thermostatic plate 9 can generate heat on one side and absorb heat on the other side. The heat release direction can be adjusted by adjusting the power-on direction, thereby meeting the demand for temperature control.

[0033] The humidity control mechanism includes a circulating water pump 14 installed inside the humidity control chamber 5, a water inlet of the circulating water pump 14 is installed with a water pumping pipe 15, a water outlet of the circulating water pump 14 is installed with a water return pipe 16, the water pumping pipe 15 and the water return pipe 16 are both connected to the embedded box 2, a water supply pipe 17 is installed at the upper end of the embedded box 2, the embedded box 2 is buried underground, and the embedded box 2 is filled with water. Since the underground temperature is relatively stable, the temperature of the water stored in the embedded box 2 is kept at a constant temperature, which is convenient for use;

[0034] The return pipe 16 passes through the temperature control chamber 4. When the temperature is controlled, the excess heat generated by the thermostatic plate 9 or when heat absorption is required can be exchanged with the circulating water flow, and the heat of the circulating water flow is exchanged with the underground environment, which is relatively stable as a whole, so that the thermostatic plate 9 can operate effectively for a long time, while ensuring the output of external energy. The temperature control process requires the return pipe 16 and the pumping pipe 15 to circulate water;

[0035] A circulating water inlet pipe 18 and a circulating water outlet pipe 19 are respectively installed on the side walls of the water extraction pipe 15 and the water return pipe 16. The circulating water inlet pipe 18 and the circulating water outlet pipe 19 are branch pipes that can inject water into the humidity control chamber 5 and circulate the water inside the humidity control chamber 5 so that the temperature of the water used for humidification is appropriate and will not affect the ambient temperature. Electromagnetic valves are provided in the water extraction pipe 15, the water return pipe 16, the circulating water inlet pipe 18 and the circulating water outlet pipe 19, which can be individually controlled to open and close, thereby completing water injection and different circulation requirements.

[0036] A humidifying water pump 20 is installed inside the humidity control chamber 5, a humidifying water pipe 21 is installed at the water outlet of the humidifying water pump 20, a humidifying box 22 is installed on the outer wall of the management box 1, the humidifying water pipe 21 is connected to the humidifying box 22, and a plurality of water spray pipes 23 are installed at the upper end of the humidifying box 22. The water spray pipes 23 are arranged to be inclined upward, and the water spray pipes 23 are provided with an atomizing head, which can spray the water flow in atomized form, thereby improving the humidification effect.

[0037] The concentration control mechanism includes a partition 27 fixed inside the concentration control chamber 6, an absorption box 28 is installed on the upper end of the partition 27, absorption particles are placed inside the absorption box 28, the absorption particles are sodium hydroxide particles, the lower half of the concentration control chamber 6 is filled with absorption liquid, the absorption liquid is sodium hydroxide solution, a second fan 29 is installed on the inner wall of the concentration control chamber 6, a second air inlet pipe 30 is installed at the air inlet of the second fan 29, a transfer pipe 31 and a second air outlet pipe 34 are installed through the upper end of the partition 27, and the upper port of the second air outlet pipe 34 passes through the management box 1 and is connected to the outside.

[0038] A gas storage tank 32 is installed on the top of the management box 1, and a plurality of gas filling pipes 33 are installed through the side wall of the gas storage tank 32. The gas filling pipes 33 are distributed around and can evenly spray carbon dioxide gas.

[0039] The absorption box 28 is a hollow structure, the lower end of the transfer pipe 31 is located below the liquid level of the absorption liquid, and the lower end of the second air outlet pipe 34 is located above the liquid level of the absorption liquid, which can avoid the sodium hydroxide from easily overflowing. During the airflow transfer process, basic absorption is first obtained, and then full absorption is obtained, thereby completing effective carbon dioxide absorption treatment, and the airflow humidity will not be greatly affected.

[0040] In the present invention, the temperature, humidity and carbon dioxide concentration in the planting greenhouse are monitored by sensors. When the temperature is unbalanced, the temperature regulating plate 9 is controlled to work, and the first fan 11 injects external air into the temperature control chamber 4 through the first air inlet pipe 12, and then discharges it through the first air outlet pipe 13. In the process, heat is exchanged with the heat transfer rod 10, so that the temperature in the planting greenhouse is regulated by air flow. Since the temperature regulating plate 9 can be used for cooling or heating, it is only necessary to control the power supply direction to achieve effective temperature regulation, and the temperature regulation is not carried out in the form of exchanging air with the outside of the greenhouse, so the air humidity and carbon dioxide concentration inside the greenhouse will not change, thereby completing the regulation of a single variable, and the regulation is accurate and effective;

[0041] When the air in the greenhouse is dry, the humidification water pump 20 transfers the water in the humidity control chamber 5 to the humidification box 22, and then sprays it out through the water spray pipe 23, thereby achieving effective humidification over a large range, and the internal induced draft fan of the diffusion box 24 works, and the air flow is sprayed upward from the bottom of the management box 1, so that the water vapor diffuses quickly, thereby achieving comprehensive humidification;

[0042] The water flow inside the humidity control chamber 5 is extracted from the embedded box 2 by the circulating water pump 14. When the humidity control chamber 5 is replenished with water, the water flow inside the embedded box 2 enters the water extraction pipe 15, and then is transferred to the water return pipe 16, and finally enters the humidity control chamber 5 through the circulating water outlet pipe 19. After a period of water injection, the lower end of the water extraction pipe 15 is closed, and the circulating water inlet pipe 18 is opened. Under the action of the circulating water pump 14, the water flow inside the humidity control chamber 5 starts to circulate by itself, and passes through the temperature control chamber 4, so that the water flow temperature inside the humidity control chamber 5 is controlled, thereby reducing the impact on the ambient temperature in the subsequent spraying and humidification process, and avoiding repeated regulation;

[0043] When it is detected that the carbon dioxide concentration in the greenhouse is low, the gas filling pipe 33 can be opened to fill the greenhouse with carbon dioxide, so that the carbon dioxide concentration in the greenhouse is effectively controlled. When there are too many people entering the greenhouse, resulting in an excessively high carbon dioxide concentration in the greenhouse, the second fan 29 can be started to introduce external air into the concentration control chamber 6. The airflow first passes through the absorption box 28 and contacts with the sodium hydroxide particles to obtain basic absorption treatment, and then enters the sodium hydroxide solution through the transfer pipe 31 for sufficient absorption treatment, and finally is discharged from the second air outlet pipe 34, completing the effective carbon dioxide absorption treatment, so that the carbon dioxide concentration is controlled;

[0044] In addition, the moisture absorbed by the sodium hydroxide particles will be replenished when the airflow passes through the sodium hydroxide solution, thereby avoiding the impact on the environmental humidity. The replenishment and absorption process of carbon dioxide does not involve exchange with the external air, so the impact on the temperature and humidity inside the greenhouse is very small, which can reduce the difficulty of regulation and will not impact the agricultural products in the greenhouse.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
