[0025] In order to solve the problem that the temperature and humidity collection of greenhouses is limited in the prior art, resulting in poor accuracy in actual temperature and humidity control of the greenhouses and inconvenience in acquiring collected data, the utility model provides a greenhouse lighting supplementary light device, such as Figure 1As shown, it mainly includes a power module 10, a lighting module 20 and a temperature and humidity acquisition module 30. The lighting module 20 and the temperature and humidity acquisition module 30 share the power provided by the power module 10. The temperature and humidity acquisition module 30 includes a temperature and humidity acquisition unit, a main control unit and a remote communication unit connected in communication. It integrates lighting fill light and temperature and humidity acquisition. The fill light area is consistent with the area where the crops are located. The corresponding temperature and humidity acquisition points are highly consistent with the environment of the crops, which can effectively improve the validity of the collected temperature and humidity data. The collected temperature and humidity data can be sent to the control terminal 300 through the remote communication unit. The control terminal 300, for example, includes a mobile phone, an air-conditioning system, a ventilation system, etc., which is convenient for viewing temperature and humidity data, or automatically controlling the working status of the air-conditioning system and the ventilation system according to the temperature and humidity data, and automatically adjusting the temperature and humidity conditions in the greenhouse.

[0026] The greenhouse lighting fill light device provided by the utility model integrates temperature and humidity collection with lighting fill light, which can reduce the temperature and humidity collection cost, and at the same time improve the collection and viewing efficiency of temperature and humidity data, providing convenience for accurate control of the environment in the greenhouse.

[0027] To realize power supply for lighting and temperature and humidity collection, in this embodiment, Figure 2 As shown, the power module 10 includes a photovoltaic unit 11, an energy storage unit 22 and a voltage transformer and voltage regulator unit 23. The photovoltaic unit 11 converts solar energy into electrical energy and stores it in the energy storage unit 22. The voltage transformer and voltage regulator unit 23 draws power from the energy storage unit 22 and provides a 3.3V regulated output at the regulated output end of the voltage transformer and voltage regulator unit 23 after the voltage transformer and voltage regulator conversion.

[0028] Considering the applicable environment of the greenhouse, in this embodiment, the energy storage unit 22 includes an energy storage capacitor, which has a fast response speed, a long life, and low maintenance requirements, which can reduce the cost of greenhouse implementation, and the supplementary lighting time required for the greenhouse is generally not too long in a day, and the use of energy storage capacitors can generally meet the energy supply requirements. In an optional embodiment, the input end of the energy storage unit 22 is also connected to the power grid to draw electricity from the power grid when the solar energy supply is insufficient.

[0029] The voltage stabilizer U1 of the transformer and voltage stabilizing unit 23 can adopt an AMS1117 type voltage stabilizer. A first capacitor C1 is also connected between the voltage stabilizing output terminal of the transformer and voltage stabilizing unit 23 and the ground, which can further improve the stability of its output voltage, ensure the power supply reliability of the lighting module 20 and the temperature and humidity collection module 30, and further ensure the reliability of its lighting and temperature and humidity collection.

[0030] In this embodiment, the light source of the lighting module 20 is an LED light source D0, which has high light efficiency. Figure 3 As shown, the lighting module 20 further includes a driving unit 21, which obtains 3.3V power from the power module 10 and drives the LED light source D0 to emit light after voltage boosting.

[0031] The driving unit 21 is mainly composed of a boost converter U2. The power supply end (VIN pin) of the boost converter U2 is connected to the power input end of the driving unit 20 to access the 3.3V power supply provided by the power module 10. A photosensitive switch U0 is also connected in series between the power supply end and the enable end (EN pin) of the boost converter U1. When natural light is insufficient, the photosensitive switch U0 is turned on, which can automatically turn on the boost converter U2 to drive the LED light source D0 to emit light for fill light.

[0032] Among them, the boost converter U2 can use the MT3608B power chip, which can meet the driving voltage requirements of the LED light source D0.

[0033] A first resistor R1 is also connected between the enable end of the boost converter U2 and the photosensitive switch U0, which can be used as a current limiting resistor to prevent current pulses caused by switching transients, external interference, etc. from damaging the boost converter U2, thereby ensuring the working reliability of the drive unit 21 and improving the reliability of lighting fill light control.

[0034] The temperature and humidity acquisition unit, main control unit and remote communication unit of the temperature and humidity acquisition module 30 are respectively composed of a temperature and humidity acquisition chip U4, a main controller U3 and a communication chip U5. The temperature and humidity acquisition chip U4 is connected to the main controller U3 of the main control unit according to the IIC communication protocol. The collected temperature data and humidity data are transmitted to the main controller U3, and then converted to the communication chip U5, and sent to the control terminal 300 through the communication chip U5, for example, to a mobile phone, a display set at the entrance of the greenhouse, a greenhouse ventilation system, etc., so that the user can check the temperature and humidity in the greenhouse, or the ventilation system can be used to automatically operate according to the current temperature and humidity information and the preset temperature and humidity requirements to control the temperature and humidity in the greenhouse.

[0035] To improve the reliability of data transmission, in this embodiment, the data pin (SDA) and clock pin (SCL) of the temperature and humidity acquisition chip U4 are respectively connected to one end of the second capacitor C2 through the second resistor R2 and the third resistor R3, and the other end of the second capacitor C2 is grounded, which can improve the stability of transmitted data and improve the reliability of the temperature and humidity data received by the main controller U3.

[0036] The power input terminal of the temperature and humidity acquisition module 30 is also grounded through a third capacitor C3 to improve the stability of the connected power supply and reduce the risk of errors in the temperature and humidity information acquisition data caused by power supply fluctuations.

[0037] In a specific example, the main controller U3 may adopt an STM32 microcontroller to meet data processing requirements.

[0038] Corresponding to the fill lighting demand in the greenhouse, at least two groups of lighting modules 20 and temperature and humidity collection modules 30 are provided, sharing a power module, which can provide multiple lighting fill lighting and temperature and humidity collection points. The temperature and humidity data at multiple points can improve the user's understanding of the temperature and humidity in the greenhouse, and provide convenience for the precise adjustment of the temperature and humidity in the greenhouse. In fact, the lighting fill lighting and temperature and humidity collection points can be designed according to the specific configuration of the greenhouse.

[0039] The greenhouse lighting fill light device provided by the utility model integrates temperature and humidity collection with lighting fill light, and can remotely send the collected temperature and humidity information to the control terminal, which can effectively solve the installation problem of temperature and humidity collection equipment, improve the layout flexibility and convenience of the greenhouse temperature and humidity control system, and provide convenience for the intelligent transformation of the greenhouse.
