[0031] In some embodiments, to simplify wiring, the third cable 40 is further used to transmit high voltage, for example, the communication adapter board 30 provides high voltage to the driver board 50 through the third cable 40, and the high voltage can be 24V.

[0032] The terminating matching board 60 is used to provide the output impedance of the control device to eliminate signal reflection noise in the third cable 40, thereby improving the stability of signal transmission.

The first cable 11 and the second cable 21 are used for communication as well as for transmitting low-voltage electricity; the third cable 40 is used for communication as well as for transmitting high-voltage electricity, thus simplifying wiring.

[0034] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the control device includes multiple drive boards 50 and multiple motors 57. The multiple drive boards 50 are connected in sequence between the communication adapter board 30 and the terminal matching board 60 through corresponding third cables 40. The motors 57 are connected to the third port 53 of the corresponding drive board 50.

[0035] Each third cable 40 includes a first power line 41, a second power line 42, a first signal line 45, a second signal line 46, and a third signal line 47. The communication adapter board 30 is connected to the terminal matching board 60 through the first power line 41, the second power line 42, the first signal line 45, and the second signal line 46.

[0036] Furthermore, each driver board 50 is connected to a first power line 41, a second power line 42, a first signal line 45, a second signal line 46, and a third signal line 47, respectively. The motor 57 is connected to a communication adapter board 30, a terminal matching board 60, or other driver boards 50 via the third signal line 47.

[0037] In some embodiments, the first power line 41 provides high voltage (24V) to the driver board 50, and the second power line 42 can be ground (GND). The first signal line 45 and the second signal line 46 constitute the first CAN bus, used to transmit high-level (CAN_1H) and low-level (CAN_1L) signals, respectively. The third signal line 47 is further used to configure the address of the driver board 50. For example, the third signal line 47 can be a hardware address configuration line used to transmit the ID_CONFIG signal to achieve automatic allocation of CAN bus node addresses.

[0038] In this embodiment, the communication adapter board 30 serves as the master node of the CAN bus network, and multiple driver boards 50 serve as slave nodes. The first CAN bus, consisting of the first signal line 45 and the second signal line 46, is sequentially connected through the multiple driver boards 50. The multiple driver boards 50 are connected between the communication adapter board 30 and the terminal matching board 60.

[0039] To enable the communication adapter board 30 to communicate with each driver board 50, a unique address needs to be configured for each slave node. The communication adapter board 30 configures the address for each slave node via the third signal line 47.

[0040] The communication adapter board 30 sets the ID_CONFIG signal of the third signal line 47 connected to the communication adapter board 30 to a high level. After receiving the high level through the third signal line 47, the driver board 50 completes its own address configuration. Subsequently, the driver board 50 sets the corresponding output ID_CONFIG signal to a high level and transmits it to the next-level driver board 50 through the third signal line 47, triggering the next-level driver board 50 to perform address configuration. This process is passed sequentially until all driver boards 50 have completed address configuration.

[0041] After the address configuration is completed, the communication adapter board 30 communicates with each driver board 50 through the first CAN bus, thereby controlling the corresponding connected motor 57 to work.

[0042] The control device in this embodiment includes multiple drive boards 50 and multiple motors 57. The drive boards 50 are connected between the communication adapter board 30 and the terminal matching board 60 via corresponding third cables 40. Each motor 57 is connected to a third port 53 of its corresponding drive board 50. Each third cable 40 includes a first power line 41, a second power line 42, a first signal line 45, a second signal line 46, and a third signal line 47. The communication adapter board 30 is connected to the terminal matching board 60 via the first power line 41, the second power line 42, the first signal line 45, and the second signal line 46. The multiple third cables 40 are sequentially connected via the multiple drive boards 50. The communication adapter board 30 automatically assigns addresses via the third signal line 47, thereby enabling the communication adapter board 30 to control the operation of the corresponding motor 57, thus improving the communication efficiency of the control system.

[0043] According to some embodiments of this application, such as Figure 3 As shown, the third cable 40 also includes a fourth signal line 43 and a fifth signal line 44. Each driver board 50 includes a CAN transceiver 54. The CAN transceiver 54 is connected to the fourth signal line 43 and the fifth signal line 44 through the first port 51 of the driver board 50. The CAN transceiver 54 is connected to the corresponding third cable 40 through the second port 52 of the driver board 50.

[0044] The CAN transceiver 54 of the driver board 50 is used to realize the physical connection and data transmission and reception between the current driver board 50 and the communication adapter board 30 and other driver boards 50. The fourth signal line 43 and the fifth signal line 44 constitute the second CAN bus, which are used to transmit high-level (CAN_2H) and low-level (CAN_2L) signals, respectively.

[0045] In this embodiment, the third cable 40 of the control device further includes a fourth signal line 43 and a fifth signal line 44. Each driver board 50 includes a CAN transceiver 54. The CAN transceiver 54 is connected to the fourth signal line 43 and the fifth signal line 44 through the first port 51 of the driver board 50. The CAN transceiver 54 is connected to the corresponding third cable 40 through the second port 52 of the driver board 50. The CAN transceiver 54 realizes the physical connection and data forwarding between the driver board 50 and the communication adapter board 30 and other driver boards 50, further improving communication efficiency.

[0046] According to some embodiments of this application, such as Figure 3 and Figure 4 As shown, the communication adapter board 30 of the control device also includes a controller 31, which is connected to the control board 20 via a second cable 21.

[0047] The controller 31 obtains input signals from the control board 20 and converts the input signals into a first signal 32 and a second signal 33. The first CAN bus, which is composed of the first signal line 45 and the second signal line 46, is used to transmit the first signal 32. The second CAN bus, which is composed of the fourth signal line 43 and the fifth signal line 44, is used to transmit the second signal 33.

[0048] The driver board 50 also includes a control unit 55 and an air valve 56. A CAN transceiver 54 is connected to the control unit 55, and the control unit 55 is connected to the air valve 56. The CAN transceiver 54 further receives a second signal 33 through a fourth signal line 43 and a fifth signal line 44. The second signal 33 is used to control the operation of the air valve 56.

[0049] In some embodiments, the controller 31 can be an MCU (Microcontroller Unit) for receiving input signals from the control board 20 and converting the input signals into a first signal 32 and a second signal 33. The first signal line 45 and the second signal line 46 form a first CAN bus for transmitting the first signal 32, and the fourth signal line 43 and the fifth signal line 44 form a second CAN bus for transmitting the second signal 33. The first signal 32 and the second signal 33 are used to control the motor 57 and the air valve 56, respectively.

[0050] After receiving the second signal 33, the CAN transceiver 54 further transmits the second signal 33 to the control unit 55. The control unit 55 receives the second signal 33 from the CAN transceiver 54 and controls the operation of the air valve 56.

[0051] In some embodiments, the control unit 55 can be a microcontroller, used to receive the signal 33 output by the CAN transceiver 54 and control the air valve 56. The fourth signal line 43 and the fifth signal line 44 constitute a second CAN bus, used to transmit high-level (CAN_2H) and low-level (CAN_2L) signals, respectively.

[0052] The third signal line 47 is a hardware address configuration line used to transmit the ID_CONFIG signal. The third signal line 47 is connected sequentially through multiple driver boards 50 to achieve automatic address allocation.

[0053] In this embodiment, the controller 31 of the communication adapter board 30 serves as the master node of the CAN bus network, and multiple driver boards 50 serve as slave nodes. The first signal line 45 and the second signal line 46 constitute the first CAN bus, and the fourth signal line 43 and the fifth signal line 44 constitute the second CAN bus. The first CAN bus and the second CAN bus are sequentially connected through the multiple driver boards 50. The multiple driver boards 50 are connected between the communication adapter board 30 and the terminal matching board 60.

[0054] To enable the controller 31 in the communication adapter board 30 to communicate with each of the driver boards 50, a unique address needs to be configured on each node of the CAN bus. The controller 31 configures the address for each node of the CAN bus via the third signal line 47.

[0055] The controller 31 of the communication adapter board 30 sets the ID_CONFIG signal of the third signal line 47 connected to the controller 31 to a high level. After receiving the high level through the third signal line 47, the driver board 50 completes its own address configuration. Subsequently, the driver board 50 sets the corresponding output ID_CONFIG signal to a high level and transmits it to the next-level driver board 50 through the third signal line 47, triggering the next-level driver board 50 to perform address configuration. This process is passed sequentially until all driver boards 50 complete address configuration.

[0056] The controller 31 of the communication adapter board 30 converts the input signal from the control board 20 into a first signal 32 and a second signal 33, and transmits the first signal 32 and the second signal 33 through the first CAN bus and the second CAN bus respectively. The first signal 32 is used to control the operation of the motor 57. The CAN transceiver 54 of each driver board 50 on the second CAN bus can receive the second signal 33. If the target address contained in the second signal 33 matches the address of the current driver board 50, the control unit 55 of that driver board 50 responds to the second signal 33 and controls the connected air valve 56 to operate; at the same time, the signal will continue to be transmitted to the next node of the second CAN bus. The communication adapter board 30 of the control device in this embodiment also includes a controller 31, which is connected to the control board 20 via a second cable 21 and receives input signals from the control board 20. The controller 31 converts the input signals into a first signal 32 and a second signal 33. A first CAN bus, consisting of the first signal line 45 and the second signal line 46, is used to transmit the first signal 32, and a second CAN bus, consisting of the fourth signal line 43 and the fifth signal line 44, is used to transmit the second signal 33. The driver board 50 also includes a CAN transceiver 54, a control unit 55, and a valve 56. The CAN transceiver 54 is connected to the control unit 55, and the control unit 55 is connected to the valve 56. The CAN transceiver 54 receives the second signal 33 via the fourth signal line 43 and the fifth signal line 44, and controls the valve 56 to operate according to the second signal 33. In this embodiment, the air valve 56 and the motor 57 are integrated into the same drive board 50, thereby realizing the integrated control of the air valve 56 and the motor 57. The controller 31 realizes the automatic configuration of the address of each drive board 50 through the third signal line 47, and then the controller 31 can control the motor 57 and the air valve 56 through the first signal 32 and the second signal 33, further improving the communication efficiency of the control device.
