[0002] In the agricultural greenhouse control technology, a plurality of cotton curtains and air curtains are installed outside the greenhouse, and the cotton curtains and air curtains are driven to be rolled up or unfolded by the motor, so that the light and temperature inside the greenhouse can be controlled, and the greenhouse can be kept in the most suitable environment for plant growth, thereby improving the economic benefit of agricultural production.

[0003] When the area of the greenhouse is relatively large, more cotton curtains and air curtains need to be installed. In order to uniformly control a plurality of cotton curtains and air curtains, a control cabinet is installed inside the greenhouse. After the management personnel press the buttons in the control cabinet, the motor can be controlled to rotate forward or reverse, so that the cotton curtain or air curtain can be rolled up or unfolded. Since a plurality of motors need to be controlled at the same time, and in addition to the function board for driving the motor, the control cabinet also needs to install circuit boards for display, control and communication, etc. If these circuit boards are combined together, it will result in a relatively large area of the circuit board, which is not convenient for production and installation. Therefore, in the prior art, the circuit boards with different functions are combined in a stacked manner, which can greatly reduce the area of a single circuit board, not only improving the convenience of installation, but also being conducive to the upgrading and expansion of the circuit board.

[0004] In the circuit board of the control cabinet, the main board has a plurality of sockets for plugging the control board and the function board, and the function board corresponds to each motor. The number of function boards plugged on the main board corresponds to the number of motors installed in the greenhouse, and the working state of the motor is controlled by the function board. Since the voltage used by the motor is relatively high, usually 220V or 380V, and the power is also relatively large, usually hundreds or even thousands of watts, the function board needs to take power from the main board to supply power to the corresponding motor. At present, the main way to take power from the main board is to connect the wires to the power taking end of the main board and the power receiving end of the function board. This power taking method needs to prepare a certain number of wires in advance, and has the problem of inconvenient operation. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] Figures 1-7 A schematic diagram of a main board and a functional board to which a plug-in structure is applied provided in an embodiment of the present application. The present application provides a circuit board plug-in structure for greenhouse control, comprising:

[0029] The locking assembly 140 is arranged on the main board 100, and the locking assembly 140 comprises a conductive column 141 and a screw rod 142. The conductive column 141 is fixed on the main board 100 and connected with the circuit on the main board 100. The screw rod 142 is screwed in the conductive column 141. Both the conductive column 141 and the screw rod 142 are made of metal.

[0030] The insertion hole is arranged on the function board, and the function board is provided with a conductive layer at the outer periphery of the insertion hole. The conductive layer is connected with the circuit on the function board. When the screw rod 142 passes through the insertion hole and press-bonds the function board on the main board 100, the screw rod 142 is in contact with the conductive layer, so that the main board 100 and the function board are electrically connected.

[0031] Exemplarily, the main board 100 and the function board are both printed circuit boards, and the copper layer thereon serves as a circuit which connects various electronic devices on the main board 100 and the function board to control the operation of the motor. The conductive layer on the function board can directly use the copper layer, or an additional layer of conductor made of tin can be arranged on the copper layer to increase the thickness of the conductive layer and avoid the wear-out of the conductive layer after long-time use.

[0032] In the embodiments of the present application, the function board has two forms, namely a first function board 200 and a second function board 300. The width of the first function board 200 is half of that of the second function board 300. The first function board 200 is used to control the air curtain motor, and the second function board 300 is used to control the cotton curtain motor. Since the cotton curtain needs a limit sensor to determine whether the cotton curtain has reached the bottom or the top during the lifting process, the second function board 300 is integrated with a circuit for communicating with the limit sensor in addition to the circuit for controlling the cotton curtain motor. Therefore, the width of the second function board 300 is greater than that of the first function board 200.

[0033] No matter whether the first function board 200 or the second function board 300 needs to be installed on the main board 100, the position of the locking assembly 140 arranged on the main board 100 needs to be fixed, and the insertion holes on the first function board 200 and the second function board 300 also need to be consistent. Since the sizes of the two function boards are different, the first function board 200 only has part of the insertion holes on the second function board 300. Therefore, no matter which function board is installed at which position, the insertion hole on the function board will correspond to the locking assembly 140 on the main board 100 to facilitate the rotation of the locking assembly 140 according to the needs of the specific function board.

[0034] In the embodiments of the present application, the main board 100 is provided with a function socket 130, and the function board is provided with a pin which is used to be inserted into the function socket 130.

After the first pin 210 on the first function board 200 is inserted into the main board 100 or the second pin 310 on the second function board 300 is inserted into the main board 100, the connection of different function boards and the main board 100 is realized.

[0036] In a possible embodiment, the locking assembly 140 further comprises a wrench 143 arranged at the top end of the screw rod 142; the insertion hole comprises a main hole 221 and a side hole 222, the diameter of the main hole 221 is the same as the diameter of the screw rod 142, the side hole 222 is arranged at the edge of the main hole 221, the length of the side hole 222 is the same as the sum of the diameter of the main hole 221 and the length of the wrench 143, after the wrench 143 passes through the main hole 221 and the side hole 222, the screw rod 142 is inserted into the main hole 221, and the wrench 143 is in contact with the conductive layer after being rotated.

[0037] Exemplarily, the side hole 222 can be one or two, when two side holes 222 are adopted, the two side holes 222 are arranged at two sides of the main hole 221 respectively. Whether one or two side holes 222 are arranged, the side hole 222 is located in the diameter direction of the main hole 221, and the wrench 143 is also located in the diameter direction of the screw rod 142, so that the wrench 143 is in the center of the screw rod 142 and the main hole 221, facilitating the rotation of the wrench 143 by the personnel.

[0038] Further, the wrench 143 comprises a conductive part and an insulating part, the conductive part is arranged at the top end of the screw rod 142, and the insulating part is arranged at the top end of the conductive part.

[0039] Specifically, the conductive part is made of metal, which can be integrally formed with the screw rod 142, and the insulating part is made of insulating material, the insulating part and the conductive part can be connected together by bonding, and the two are flush at the connection position after being connected. After the insulating part is adopted, the hand of the personnel does not contact the live part of the functional board, avoiding the injury of the personnel caused by the storage of the capacitive element on the functional board or the main board 100.

[0040] In the embodiment of the present application, the main board 100 is provided with a power connection seat 110, the power connection seat 110 is connected with the circuit on the main board 100, and the power connection seat 110 is used for connecting the power supply.

[0041] Exemplarily, the power connection seat 110 is provided with a wire insertion hole and a screw hole, a screw is screwed in the screw hole, and the wire insertion hole and the screw hole are communicated, when the wire is inserted into the wire insertion hole, the screw is tightened to press the wire in the screw hole, and the screw hole and the circuit on the main board 100 are connected through the metal sheet, so that the connection of the power supply is realized.

[0042] In a possible embodiment, the main board 100 is provided with a control socket 120, and the control socket 120 is connected with the functional socket 130 through the circuit on the main board 100.

[0043] Exemplarily, the control socket 120 internally has a plurality of pins, when the plug on the control board is plugged on the control socket 120, the connection between the control board and the main board 100 is realized, and after the conversion of the main board 100, the control board will be connected with the installed function board. After receiving the control instruction input by the person through the button, the control board will transmit it to the function board, and then realize the control of the corresponding motor.

[0044] In a possible embodiment, the main board 100 is provided with a mounting hole 150, which is used for mounting in the control cabinet.

[0045] Exemplarily, the control cabinet is internally provided with a mounting column corresponding to the mounting hole 150, and the top end of the mounting column is provided with a screw hole. When the main board 100 is mounted on the mounting column, the screw is passed through the mounting hole and screwed in the screw hole, and then the main board 100 is mounted in the control cabinet.
