[0026] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0027] The universal control unit is a mature product that supports embedded relay output boards, voltage and current input boards, fieldbus backplanes, and more. This utility model provides an electric actuator, including an electric actuator drive module 2 and a relay output module 1. Both the electric actuator drive module 2 and the relay output module 1 are embedded within a universal control unit bus backplane 3, and both receive power and communication via the universal control unit bus backplane 3, outputting a 24V power signal to drive the electric actuator.

[0028] Relay output module 1 is a switch output board. Its GD32F107 main control chip receives CAN communication messages from an external source. After processing, it outputs control signals to control the relay drive circuit, which is primarily implemented by the CJ2310 MOS tube. Relay output module 1 supports the CANOPEN protocol specification. As a CANOPEN slave device, it can communicate with any other master device that complies with the CANOPEN protocol specification. When an external master sends a CAN message, relay output module 1 parses and processes it to control the switching state of 32 relays. Each of the 32 relays is a group of normally open relays. The selected relay is JZC-32F / 005HS, with 32 relay outputs and a pin capacity of 1A / DC24V. The front panel of relay output module 1 uses a 6U 6HP panel, and the puller height is less than 15mm. The front panel and puller comply with IEEE1101.1 or IEEE1101.1. The assembly of the module front panel, puller, and plug is as follows: Figure 1 shown.

[0029] The electric push rod drive module 2 is a board that supports the embedded universal control unit. It is controlled by the relay output module 1 and outputs a 24V power supply signal to drive the electric push rod.

[0030] The universal control unit bus backplane 3 is a backplane that can support communication with multiple IO boards. The relay output module 1 and the electric rod drive module 2 are powered and communicated through the universal control unit bus backplane 3 plugged into the site. Figure 2 and Figure 3 shown.

[0031] Specifically, achieving forward and reverse rotation of a single electric pole requires reversing the voltage at the power terminals. That is, when Power Terminal I is connected to 24V and Power Terminal II is connected to GND, the pole rotates forward and extends. When Power Terminal I is connected to GND and Power Terminal II is connected to 24V, the pole retracts and reverses. Driving a single electric pole requires two normally open relays in Relay Output Module 1 and two single-pole double-throw relays in Electric Pole Drive Module 2. Two normally open relays and two single-pole double-throw relays form a group. To drive n electric poles, n corresponding groups of normally open relays and single-pole double-throw relays are required.

[0032] Take driving an electric rod as an example, Figure 4 As shown, the relay output module 1 includes a normally open relay I and a normally open relay II, and the electric rod drive module 2 includes a single-pole double-throw relay I and a single-pole double-throw relay II.

[0033] Pin III of the normally open relay I is electrically connected to pin II of the single-pole double-throw relay I through the universal control unit bus backplane 3. Pin IV of the normally open relay I is connected to the 24V power supply. Pin III of the single-pole double-throw relay I is connected to the power supply GND. Pin IV of the single-pole double-throw relay I is connected to the 24V power supply. Pin V of the single-pole double-throw relay I is connected to the power supply terminal I of the electric pole.

[0034] Pin III of the normally open relay II is electrically connected to pin II of the single-pole double-throw relay II through the universal control unit bus backplane 3. Pin IV of the normally open relay II is connected to the 24V power supply, and pin I of the single-pole double-throw relay II is connected to the power supply GND; pin III of the single-pole double-throw relay II is connected to the power supply GND, and pin IV of the single-pole double-throw relay II is connected to the 24V power supply; pin V of the single-pole double-throw relay II is connected to the power supply terminal II of the electric pole;

[0035] Relay output module 1 also includes a main control chip, drive circuit I, and drive circuit II. The main control chip receives control commands from the CAN bus and sends them to drive circuits I and II, which then send drive signals to normally open relays I and II, respectively. Drive circuit I is connected to pin I of normally open relay I, while pin II of normally open relay I is grounded. Drive circuit II is connected to pin II of normally open relay II, while pin I of normally open relay II is grounded.

[0036] In the relay output module 1, when the drive signal I is high level 5V, pin III and pin IV of the normally open relay I are connected. At this time, the output signal of pin III of the normally open relay I is high level 24V. At the same time, the drive signal II is low level, and pin III and pin IV of the normally open relay II are not connected. At this time, the output signal of pin III of the normally open relay II is not 24V. In the electric rod drive module 2, the output signal of the normally open relay I is high level 24V, which makes the normally open contact of the single-pole double-throw relay I attract. Since its normally open pin IV is 24V, the power supply terminal I of the electric rod is 24V at this time. Similarly, the output signal of the normally open relay II does not output 24V, and the normally open contact of the single-pole double-throw relay II cannot be attracted. Since its normally closed contact III is GND, the power supply terminal II of the electric rod is GND at this time. At this time, the electric rod motor rotates forward and the electric rod extends.

[0037] In the relay output module 1, when the drive signal II is high level 5V, pin III and pin IV of the normally open relay II are connected. At this time, the output signal of pin III of the normally open relay II is high level 24V. At the same time, the drive signal I is low level, and pin III and pin IV of the normally open relay I are not connected. At this time, the output signal of pin III of the normally open relay I is not 24V. In the electric rod drive module 2, the output signal of the normally open relay II is high level 24V, which makes the normally open contact of the single-pole double-throw relay II attract. Since its normally open pin IV is 24V, the power supply terminal II of the electric rod is 24V at this time. Similarly, the output signal of the normally open relay I does not output 24V, and the normally open contact of the single-pole double-throw relay I cannot be attracted. Since its normally closed pin III is GND, the power supply terminal I of the electric rod is GND at this time. At this time, the electric rod motor reverses and the electric rod retracts.

[0038] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
