Example Embodiment

[0011] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0012] like figure 1 As shown, the present embodiment provides an automatic light-filling device for greenhouse cultivation, including an illuminance sensor, a signal conditioning module, a central processing unit, an alarm module and an LED light-filling assembly, and the illuminance sensor communicates with the central processing unit through the signal conditioning module and the central processing unit. The illuminance sensor is used for conditioning the collected illuminance signal, so that the central processing unit can identify and process it, and the specific signal conditioning module includes a first-stage amplifying circuit, a baseline drift suppression circuit, a detector, Band-pass filter, secondary amplifier circuit and A/D conversion circuit.
[0013] Both the alarm module and the LED supplementary light assembly are respectively connected with the central processing unit. The alarm module is connected to the central processing unit for sending out an alarm, and the specific alarm module adopts an acousto-optic alarm. The LED supplementary light component is connected with the central processing unit to realize supplementary light manipulation. Specifically, the LED supplementary light component includes an LED lamp driving circuit and an LED high-definition supplementary light, and the LED high-definition supplementary light passes through the LED light driving circuit. connected to the central processing unit.
[0014] The present invention is not limited to the above examples, and within the scope defined by the claims of the present invention, various deformations or modifications that can be made by those skilled in the art without creative work are protected by this patent.
