[0021] Example 1:

[0022] like Figure 1-5 As shown, the greenhouse IoT environmental monitoring and control device provided by this utility model includes: a main control box 4, a power generation mechanism, a ventilation mechanism, and multiple spray monitoring mechanisms; the power generation mechanism is installed outside the greenhouse; a battery compartment 1 is installed on the power generation mechanism; a storage battery for power supply is installed in the battery compartment 1; the power generation mechanism is used to charge the storage battery; the main control box 4 is installed on the power generation mechanism; a maintenance window is provided on the main control box 4; a main cabinet door 5 with a sealed maintenance window is hinged to the main control box 4; a main controller and a main wireless communication module electrically connected to the main controller are installed inside the main control box 4; ventilation... The device is installed on the greenhouse structure to ventilate the greenhouse and is driven and controlled by a main controller. A main water pipe 40 is suspended inside the greenhouse. Various spray monitoring devices are installed intermittently inside the greenhouse and are all connected to the main water pipe 40 to monitor data such as temperature, soil moisture, and carbon dioxide concentration in different areas of the greenhouse and to perform spray irrigation. The main water pipe 40 is connected to an external water pump through an inlet pipe 26. Each spray monitoring device is equipped with a slave controller and a slave wireless communication module electrically connected to the slave controller, and each spray monitoring device is driven and controlled by its corresponding slave controller.

[0023] By installing various spray monitoring units in different areas within the greenhouse, data such as temperature, soil moisture, and carbon dioxide concentration in each area can be monitored and uploaded to a remote control center. The controller then uses the collected data to individually spray and irrigate the corresponding areas, ensuring suitable humidity for the plants. Simultaneously, the remote control center uses the collected data to determine whether ventilation is needed. When ventilation is required, the main controller controls the ventilation system to blow air, resulting in a high degree of automation and eliminating the need for manual operation. The relatively simple installation of the main control box 4, power generation mechanism, ventilation mechanism, and multiple spray monitoring units allows the environmental monitoring and regulation device to be adaptably installed in different greenhouses, with lower requirements for the greenhouse structure. The power generation mechanism charges the storage battery, thus reducing energy consumption.

[0024] Furthermore, the power generation mechanism includes a base plate 2, a column 3, a rotating cap 6, multiple horizontal support rods 8, multiple angle adjustment branches, and multiple solar panels 15; the lower end of the column 3 is fixed to the base plate 2; the rotating cap 6 is rotatably mounted on the top of the column 3; a rotating positioning bolt 7 with its end tightly pressed against the column 3 is threaded onto the rotating cap 6; each horizontal support rod 8 is horizontally fixed to the rotating cap 6; each angle adjustment branch is respectively mounted on each horizontal support rod 8, and each solar panel 15 is respectively mounted on each angle adjustment branch; each angle adjustment branch is used to adjust the pitch angle of each solar panel 15; the battery compartment 1 is mounted on the base plate 2; the solar panels 15 charge the battery through a solar power generation circuit.

[0025] The rotating cap 6 is adjustable, which drives the various angle adjustment branches to rotate through the horizontal support rods 8 until the solar panel 15 is oriented to the desired position. Tightening the rotating positioning bolt 7 can adjust the solar panel 15. The rotating cap 6 adjusts the orientation of the solar panel 15, and the angle adjustment branches adjust the pitch angle of the solar panel 15. Thus, the solar panel 15 can be adjusted according to the installation position of the power generation mechanism, so that the solar panel 15 can generate electricity efficiently during long-term use.

[0026] Furthermore, the angle adjustment branch includes a back plate 14, a positioning rod 11, a hinge rod 12, and a sliding seat 9; the lower end of the positioning rod 11 is fixed to the horizontal support rod 8; a hinge seat 13 is fixed to the upper end of the positioning rod 11 on the lower side of the back plate 14; the horizontal support rod 8 slides through the sliding seat 9; an angle positioning bolt 10, with its end tightly pressed against the horizontal support rod 8, is threaded onto the sliding seat 9; one end of the hinge rod 12 is hinged to the sliding seat 9, and the other end is hinged to the lower side of the back plate 14; the solar panel 15 is mounted on the upper side of the back plate 14. The sliding seat 9 drives the hinge rod 12 to move along the horizontal support rod 8, and the back plate 14 follows the movement of the sliding seat 9, pitching and swinging until the solar panel 15 reaches the desired angle. The angle positioning bolt 10 is then tightened for positioning, thereby achieving angle adjustment of the solar panel 15.

[0027] Furthermore, the ventilation mechanism includes multiple ventilation units; each ventilation unit includes an exhaust fan 23, an opening / closing branch, and two translation plates 20; the opening / closing branch includes a translation drive motor 17 and two translation drive screws 18; multiple ventilation windows are spaced out on the greenhouse structure; the exhaust fans 23 of each ventilation mechanism are respectively embedded in each ventilation window; parallel plates 16 are fixed on both the upper and lower sides of the exhaust fan 23, and the exhaust fan 23 is electrically connected to the main controller through a fan drive circuit; multiple traveling rollers 21 that travel on the lower side of the two translation plates 20 are installed on the lower edge of each translation plate 20; on the upper side... The translation plate 20 is provided with translation adjustment holes; translation adjustment seats 19 that pass through the translation adjustment holes are fixed on the upper edges of the two parallel plates 16; two translation drive screws 18 are rotatably mounted on the upper translation plate 20; the two translation drive screws 18 have the same pitch but opposite directions of rotation; the translation drive motor 17 is used to drive the two translation drive screws 18 to rotate synchronously, and is electrically connected to the main controller through the translation drive circuit; the two translation drive screws 18 are threaded through the two translation adjustment seats 19 respectively; the two translation plates 20 are used to relatively approach and shield the air outlet of the exhaust fan 23.

[0028] The translation drive motor 17 drives the two translation drive screws 18 to rotate under the control of the main controller, so that the two translation adjustment seats 19 move relative to each other along the translation adjustment holes, thereby driving the two translation plates 20 to move closer or further apart, thus opening or blocking the air duct of the exhaust fan 23; the exhaust fan 23 operates under the control of the controller, so that the airflow blows into the greenhouse to achieve ventilation; the traveling rollers 21 reduce the friction between the translation plates 20 and the parallel plate 16 on the lower side, ensuring that the two translation plates 20 can move stably.

[0029] Furthermore, the spray monitoring mechanism includes a control box 28, a monitoring unit, and a spraying unit; the spraying unit includes a lifting adjustment branch and a spraying branch; the spraying branch includes a water tank 27, a connecting pipe 31, and two spraying pipes 33;

[0030] A lifting and adjusting branch is installed inside the greenhouse, and a water tank 27 is installed on top of the lifting and adjusting branch. The height of the water tank 27 is adjusted by the lifting and adjusting branch. A control box 28 is fixed on top of the water tank 27. The controller and the wireless communication module are both located inside the control box 28. The water tank 27 is connected to the main water pipe 40 via a connecting pipe 31. An electromagnetic water valve 25, which is electrically connected to the controller, is connected in series on the connecting pipe 31. Two drain pipes 38 are installed in a continuous manner at the bottom of the water tank 27. A limit plate 36 is sealed and fixed at the lower end of each of the two drain pipes 38. A connecting ring 35 is rotatably and sealingly fitted on each of the two drain pipes 38. An annular groove is coaxially provided on the inner wall of the connecting ring 35. Two spray pipes 33 are respectively fixed in a continuous manner on the two connecting rings 35 and connected to the corresponding annular grooves. Multiple water inlets 39 connected to the corresponding annular grooves are provided on each of the two drain pipes 38. Multiple nozzles 34 are spaced apart on the lower side wall of each of the two spray pipes 33.

[0031] The spray pipe 33 is rotated by the cooperation of the drain pipe 38, the limiting plate 36, the connecting ring 35 and the spray pipe 33, so that the rotation can be adjusted according to the needs of the spraying position. The monitoring unit detects the data of the area and the controller determines whether spraying irrigation is needed based on the data. When spraying irrigation is needed, the electromagnetic water valve 25 is opened under the control of the controller, so that the water pumped by the external water pump enters the water tank 27 through the water inlet pipe 26, the main water pipe 40 and the corresponding connecting pipe 31, and is then sprayed on the plants in the corresponding area through the nozzles 34 on the two spray pipes 33, so as to realize the spraying irrigation of the area.

[0032] Furthermore, the lifting adjustment branch includes a lifting adjustment tube 52, a lifting adjustment rod 49, and a support plate 53; the lower end of the lifting adjustment tube 52 is fixed at the center of the support plate 53; multiple reinforcing ground nails 54 are provided on the lower side edge of the support plate 53; the lower end of the lifting adjustment rod 49 is inserted into the upper end of the lifting adjustment tube 52; multiple adjustment holes 50 are provided at intervals on the lifting adjustment rod 49; a lifting positioning bolt 51 with its end inserted into one of the adjustment holes 50 is threaded into the upper opening of the lifting adjustment tube 52.

[0033] Furthermore, the monitoring unit includes a sensor support structure, a light sensor 29, a temperature sensor, a barometric pressure sensor, a soil moisture sensor 48, and a carbon dioxide sensor 46; the sensor support structure includes a measurement positioning pin 44 and a water-blocking plate 47.

[0034] A light sensor 29 is mounted on the top surface of the slave control box 28 and is electrically connected to the slave controller; a detection slot 30 is provided on one vertical side of the slave control box 28; a temperature sensor and a pressure sensor are both mounted in the detection slot 30 and are both electrically connected to the slave controller; a memory electrically connected to the slave controller is installed in the slave control box 28.

[0036] The position of the detection slot 30 prevents the temperature sensor and air pressure sensor from direct sunlight and wind. The support plate 45, measuring positioning pin 44, and crossbar 43 support the lower end of the protective hose 42, allowing the water baffle 47 to shield the soil moisture sensor 48 from direct water spray. This prevents water from being sprayed directly onto the carbon dioxide sensor 46 and soil moisture sensor 48, and also lowers the installation position of the carbon dioxide sensor 46 to detect the concentration of sinking carbon dioxide. The protective hose 42 protects the cables of the carbon dioxide sensor 46 and soil moisture sensor 48 from water and dust. A light sensor is also used. 29. Temperature sensor, air pressure sensor, soil moisture sensor 48, and carbon dioxide sensor 46 monitor the light intensity, temperature, air pressure, soil moisture, and carbon dioxide concentration data of the area and store them in the memory. Every once in a while, the controller uploads the data in the memory to the remote control center through the wireless communication module, so that the remote control center can monitor each area in the greenhouse. The remote control center controls the ventilation mechanism to open and blow air into the greenhouse based on the uploaded data through the main controller. At the same time, the soil moisture data collected by the soil moisture sensor 48 can also help the controller determine whether spraying irrigation is needed.

[0037] In the greenhouse IoT environmental monitoring and control device provided by this utility model, both the main controller and the slave controller adopt existing single-chip microcomputer control modules; both the main wireless communication module and the slave wireless communication module adopt existing wireless communication modules; the electromagnetic water valve 25 adopts existing electromagnetic water valves; the exhaust fan 23 adopts existing exhaust fans, and the fan drive circuit adopts the corresponding exhaust fan drive circuit; the temperature sensor, light sensor 29, soil moisture sensor 48, carbon dioxide sensor 46, and air pressure sensor all adopt existing sensors; the translation drive motor 17 adopts existing stepper motors, and the translation drive circuit adopts the corresponding stepper motor drive circuit.

Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
