Technical Field

[0001] This application relates to the technical field of circuit boards, and in particular to a multi-channel switch circuit board. Background Technology

[0002] When controlling multiple devices, multiple switches are required. However, in different usage scenarios, such as motors, there are forward and reverse rotations, and existing circuit boards cannot achieve this function. Utility Model Content

[0003] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide a multi-channel switch circuit board, which has the advantage of being able to control the forward and reverse rotation of multiple motors.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A multi-channel switching circuit board includes a board body, on which an MCU and a multi-channel switching circuit are provided. The switching circuit includes a switch one, a switch two, and a switch three connected in parallel. One end of each switch one, switch two, and switch three is electrically connected to a power supply, and the other end is electrically connected to the MCU.

[0006] By adopting the above technical solution, the forward rotation, reverse rotation, and shutdown of the motor can be controlled by using a multi-channel switching circuit and setting three switches in each switching circuit.

[0007] In a preferred embodiment, this application may be further configured to include multiple display circuits, with each display circuit corresponding to a multiple switching circuit. Each display circuit includes a display unit 1 and a display unit 2, which are connected in parallel. One end of each display unit 1 and display unit 2 is electrically connected to a power supply, and the other end is electrically connected to an MCU.

[0008] By adopting the above technical solution, in use, multiple display circuits and multiple switching circuits correspond one-to-one. Display unit one and display unit two are used to display the switching status in the switching circuit. If switch one is turned on, display unit one will display; if switch two is turned on, display unit two will display; if switch three is turned on, neither display unit one nor display unit two will display.

[0009] In a preferred embodiment, this application may be further configured to include multiple Ethernet PHY units, which are electrically connected to the MCU, and the Ethernet PHY units are connected to RJ45 interfaces.

[0010] By adopting the above technical solution, when using multiple circuit boards, adjacent circuit boards can be connected through the RJ45 interface.

[0011] In a preferred embodiment, this application may be further configured to include a multi-channel fan circuit, wherein the fan circuit includes switch four and switch five, which are connected in parallel, with one end of switch four and switch five electrically connected to a power supply and the other end electrically connected to an MCU.

[0012] By adopting the above technical solution, the existence of the multi-fan circuit enables the control of multiple fans, and switches four and five are used to control the start and stop of the fans. Attached Figure Description

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] Reference Figure 1 and Figure 2 The present application discloses a multi-channel switching circuit board, which includes a board body. The board body is provided with an MCU1, a multi-channel switching circuit 2, multiple display circuits 4, multiple Ethernet PHY units and a multi-channel fan circuit 3. In this embodiment, the switching circuit 2 and the display circuit 4 are both eight-channel, and the Ethernet PHY unit and the fan circuit 3 are both two-channel.

[0018] The switching circuit 2 includes switch 1 21, switch 2 22 and switch 3 23, which are connected in parallel. One end of switch 1 21, switch 2 22 and switch 3 23 is electrically connected to the power supply and the other end is electrically connected to MCU1. Multiple display circuits 4 and multiple switching circuits 2 correspond one-to-one. Display circuit 4 includes display unit 1 41 and display unit 2 42, which are connected in parallel. One end of display unit 1 41 and display unit 2 42 is electrically connected to the power supply and the other end is electrically connected to MCU1.

[0019] Both display unit 1 (41) and display unit 2 (42) can use LED beads to display the switch status in the corresponding switching circuit 2. For example, if switch 1 (21) is on, display unit 1 (41) will display; if switch 2 (22) is on, display unit 2 (42) will display; if switch 3 (23) is on, neither display unit 1 (41) nor display unit 2 (42) will display.

[0020] Multiple Ethernet PHY units are electrically connected to MCU1. Each Ethernet PHY unit has an RJ45 interface. When using multiple circuit boards, adjacent circuit boards can be connected via the RJ45 interface. For example, with two circuit boards, circuit board one is connected to the control center via a network cable, and circuit board two is connected to circuit board one via a network cable. Therefore, circuit board two does not need to be connected to the control center.

[0021] The fan circuit 3 includes switch 4 31 and switch 5 32, which are connected in parallel. One end of switch 4 31 and switch 5 32 is electrically connected to the power supply, and the other end is electrically connected to MCU1.

[0022] The implementation principle of this embodiment is as follows: During use, the forward, reverse and stop control of the motor can be realized by different buttons. When multiple circuit boards are used, adjacent circuit boards can be connected through the RJ45 interface.

[0023] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
