Description

Technical Field

[0001] The present invention relates to the technical field of plant lights, and particularly to a plant light control system, a plant light control board, and a control method thereof. Background Art

[0002] Through application tests, plant lights are very suitable for the growth, flowering, and fruiting of plants. Generally, indoor plants and flowers will grow worse and worse over time due to the lack of natural light. By irradiating with plant lights with the required brightness and spectrum (light quality combination) for plants, not only can their growth be promoted, but also the flowering period can be extended and the quality of the flowers can be improved.

[0003] However, the existing plant lights on the market are often of a single spectrum. For example, if seedling raising is required, only a single seedling raising spectrum can be used for seedling raising; if flowering is required, a plant light with a spectrum that can promote flowering needs to be purchased separately; if fruiting is required, a plant light with a spectrum that can promote fruiting needs to be purchased separately, resulting in a relatively high purchase cost.

[0004] In addition, the control methods of existing plant lights are single and troublesome to use. Moreover, if an existing terminal wants to remotely control multiple plant lights by wire at the same time, all control boards often need to be directly connected to the terminal, resulting in a large number of messy wires.

[0005] Therefore, in this patent application of the present invention, the applicant has carefully studied a plant light control system, a plant light control board, and a control method to solve the above problems. Summary of the Invention

The first voltage output terminal of the main control module is connected to the first negative input terminal, and the second voltage output terminal of the main control module is connected to the first positive input terminal;

[0022] The second voltage comparator has a second positive input terminal, a second negative input terminal, and a second output terminal for connecting to the power supply of the plant light. The first voltage output terminal of the main control module is connected to the first positive input terminal, and the second negative input terminal is grounded through a resistor.

[0046] The present invention will be further described below in conjunction with the attached drawings and the detailed implementation mode.

[0047] As Figures 1 to 3 shown, a plant lamp control board includes a circuit board, a first gear adjustment knob 26 for brightness gear adjustment, a second gear adjustment knob 27 for spectral gear adjustment, a main control module 21 arranged on the circuit board, a communication module 22 for connecting to the terminal 14, and a dimming module 25 for electrically connecting to the plant lamp power supply 13;

[0048] The main control module 21 is electrically connected to the communication module 22, the first gear adjustment knob 26, the second gear adjustment knob 27, and the dimming module 25 respectively; in this embodiment, the communication module 22 is an RS485 module, and of course it can also be other communication modules 22, which is not limited here.

[0049] The first gear adjustment knob 26 and the second gear adjustment knob 27 are symmetrically arranged. An auxiliary circuit board is also included, and both the first gear adjustment knob 26 and the second gear adjustment knob 27 are arranged on the auxiliary circuit board.

[0050] The manual adjustment brightness module 261 and the terminal adjustment brightness module 262 are alternately connected to the first gear adjustment knob 26, and both the manual adjustment brightness module 261 and the terminal adjustment brightness module 262 are electrically connected to the main control module 21.

[0051] When the first gear adjustment knob 26 is rotated to be connected to the terminal adjustment brightness module 262, the main control module 21 can receive signals from the terminal 14 through the communication module 22 to control the dimming module to output signals for adjusting the brightness;

[0052] When the first gear adjustment knob 26 is rotated to be connected to the manual adjustment brightness module 261, the main control module 21 can control the dimming module to output signals for adjusting the brightness by receiving control signals from the first gear adjustment knob 26;

[0053] And / or:

[0054] The manual adjustment spectral module 271 and the terminal adjustment spectral module 272 are alternately connected to the second gear adjustment knob 27; both the manual adjustment spectral module 271 and the terminal adjustment spectral module 272 are electrically connected to the main control module 21.

[0055] When the second gear adjustment knob 27 is rotated to be connected to the terminal adjustment spectrum module, the main control module can receive signals from the terminal through the communication module 22 to control the dimming module to output signals for adjusting the spectrum;

[0056] When the second gear adjustment knob 27 is rotated to be connected to the manual adjustment spectrum module 271, the main control module can control the dimming module to output signals for adjusting the spectrum by receiving control signals from the second gear adjustment knob 27.

[0057] In this embodiment, both the terminal brightness adjustment module 262 and the terminal adjustment spectrum module are in the EXT gear. When rotated to the EXT gear, the adjustment mode for the terminal 14 to control the spectrum or brightness is realized.

[0058] The manual brightness adjustment module 261 includes five gradually increasing brightness gears, and the brightness gears are successively the 0% brightness gear, 40% brightness gear, 60% brightness gear, 80% brightness gear, and 100% brightness gear. The EXT gear of the first gear adjustment knob 26 is the next gear of the 100% brightness gear.

[0059] By default, the first gear adjustment knob 26 is in the EXT gear. At this time, the function of manually adjusting the brightness is turned off. When the user continues to rotate the gear adjustment knob backward, the brightness continues to decrease, and when rotated to the end, the brightness is the lowest, which is 0% brightness.

[0060] The manual adjustment spectrum module 271 includes the SPRIN spectrum gear, SUM spectrum gear, and AUTM spectrum gear. The EXT gear of the second gear adjustment knob 27 is the next gear of the AUTM spectrum gear.

[0061] By default, the second gear adjustment knob 27 is in the EXT gear. At this time, the function of manually adjusting the spectrum is turned off. When the user continues to rotate the gear adjustment knob backward, the spectrum changes, and when rotated to the end, the spectrum is the SPRIN spectrum. In this embodiment, the SPRIN spectrum gear is the spring spectrum mode, and its blue light spectrum is at the highest value; the SUM spectrum gear is the summer spectrum mode, and its blue light spectrum is between the highest value and the lowest value; the AUTM spectrum gear is the autumn spectrum mode, and its blue light spectrum is at the lowest value.

[0062] In this embodiment, a network interface for connecting the terminal 14 or other plant lamp control boards is further provided on the circuit board. The network interface is an RJ11 interface or an RJ12 interface. In this embodiment, the network interface is an RJ12 interface. The communication module 22 is connected to the network interface. At least two network interfaces are provided, and at least two network interfaces are connected in parallel. In this embodiment, two network interfaces are provided, which are respectively defined as the first network interface 23 and the second network interface 24.

[0063] The dimming module 25 includes a first voltage comparator and a second voltage comparator;

[0064] The first voltage comparator has a first positive input terminal, a first negative input terminal, and a first output terminal for connecting to the plant lamp power supply 13. The first voltage output terminal of the main control module 21 is connected to the first negative input terminal, and the second voltage output terminal of the main control module 21 is connected to the first positive input terminal;

[0065] The second voltage comparator has a second positive input terminal, a second negative input terminal, and a second output terminal for connecting to the plant lamp power supply 13. The first voltage output terminal of the main control module 21 is connected to the first positive input terminal, and the second negative input terminal is grounded through a resistor.

[0066] Next, the general working principle will be briefly described:

[0067] When adjusting to 40% brightness, when the first gear adjustment knob 26 is rotated to the 40% brightness gear, the first voltage output terminal of the main control module 21 outputs a corresponding voltage signal to the second positive input terminal, and the second output terminal outputs a corresponding signal to the plant lamp power supply 13 to achieve brightness gear adjustment;

[0068] When adjusting to the spring spectrum mode, when the second gear adjustment knob 27 is rotated to the SPRIN spectrum gear, the second voltage output terminal of the main control module 21 outputs a corresponding voltage signal to the first positive input terminal. The first voltage output terminal of the main control module 21 is connected to the first negative input terminal, and the first output terminal outputs a corresponding signal to the plant lamp power supply 13 to achieve spectrum gear adjustment.

[0069] A plant lamp control system includes a terminal 14, at least two plant lamp control boards, and at least two plant lamp power supplies 13. The plant lamp control board is the described plant lamp control board;

[0070] The terminal 14 is connected to at least two plant lamp control boards, and each plant lamp control board is connected to a plant lamp power supply 13 through a communication module 22.

[0071] Network interfaces for connecting to the terminal 14 are provided on the circuit boards of at least two plant lamp control boards. There are at least two network interfaces, and at least two network interfaces are connected in parallel;

[0072] Among at least two plant lamp control boards, the network interface of one of them is connected to the terminal 14 through a first network cable to achieve that one of them is connected to the terminal 14 through its network interface and the communication module 22;

[0073] One of the network interfaces is connected to the other network interface through a second network cable so that the other is connected to the terminal 14 through the other network interface and the communication module 22.

[0074] In this embodiment, as Figure 2 shown, there are two plant lamp control boards, which are respectively defined as the first plant lamp control board 11 and the second plant lamp control board 12, and each of the first plant lamp control board 11 to the second plant lamp control board 12 is electrically connected to a plant lamp power supply 13.

[0075] Then the first network interface 23 of the first plant lamp control board 11 is connected to the terminal 14, and the second network interface 24 of the first plant lamp control board 11 is connected to the first network interface 23 of the second plant lamp control board 12. At this time, the control signal of the terminal 14 is transmitted to the two plant lamp control boards through two channels, where:

[0076] a. The control signal of the terminal 14 is sent to the main control module 21 of the first plant lamp control board 11 through the first network interface and the communication module 22 of the first plant lamp control board 11;

[0077] b. The control signal of the terminal 14 is sequentially sent to the main control module 21 of the second plant lamp control board 12 through the first network interface 23 of the first plant lamp control board 11, the second network interface 24 of the first plant lamp control board 11, the first network interface 23 of the second plant lamp control board 12, and the communication module 22 of the second plant lamp control board 12; Therefore, the terminal 14 can simultaneously control the two plant lamp control boards to send signals for controlling the brightness and spectrum of the plant lamp to the plant lamp power supply 13.

[0078] A plant lamp control method, which is based on a plant lamp control board and includes

[0079] When the first gear adjustment knob 26 or the second gear adjustment knob 27 is rotated to the corresponding terminal adjustment module (i.e., the EXT gear), remote brightness or spectrum gear adjustment can be performed through the terminal 14;

[0080] When the first gear adjustment knob or the second gear adjustment knob is rotated to the corresponding manual adjustment module (i.e., the non-EXT gear), manual brightness or spectrum gear adjustment can be performed.

[0081] The key design point of the present invention is that corresponding manual adjustment modules and corresponding terminal adjustment modules are alternately connected to the corresponding gear adjustment knobs. When rotated to the corresponding adjustment module, terminal control or manual adjustment control can be achieved. It combines the near-distance gear adjustment knob control and the wired remote control of the brightness and spectrum of the light board, with flexible adjustment methods, bringing convenience to the users. In particular, in the plant light control system, only one plant control board needs to be electrically connected to the terminal, and other plant control boards are indirectly connected to the terminal, then the brightness and spectrum of multiple light boards can be controlled simultaneously by the terminal through wired remote control, greatly reducing the chaos of wiring, increasing the use space of the circuit board, and ensuring the stability and reliability of the product during use; and, the control method is simple, only by rotating to the corresponding terminal adjustment module, the wired remote control can be switched to.

[0082] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
