The power interface module 1 is a channel for an external direct current power supply to enter the intelligent control actuator, and the direct current outside the actuator is connected into the actuator, so that a power supply is provided for the operation of the actuator. In one embodiment of the invention, the external DC power source can be 12V-24V DC.
The power conversion module 4 is communicated with the power interface module 1, and converts direct current input by the power interface module 1 into two paths of low-voltage direct current so as to ensure the power consumption requirements of low-voltage electronic components in the intelligent control actuator, wherein the voltage of the two paths of direct current is set according to the model of selected electronic components of each module in the actuator, for example, the two paths of direct current can be selected to be 12V direct current and 5V direct current. In one embodiment of the present invention, the 12V dc output by the power conversion module 4 is electrically connected to the relay driver circuit module 8, the relay module 9, and a low dropout regulator (LDO) inside the power conversion module 4. The 12V direct current is converted into 5V direct current through the low-dropout linear regulator and is output by the power conversion module 4. The 5V direct current is communicated with the 485 isolation module 5, the optical coupling isolation input module 6 and the micro control unit 7 through the power supply conversion module.
The communication interface module 2 adopts an RS-485 communication interface which is a channel for an external intelligent gateway to control a command signal to enter an intelligent control actuator. The user of the intelligent electrical equipment inputs the control command (including the operation state regulating signal of the external electrical equipment of the actuator) of the electrical equipment into the intelligent gateway through the intelligent control terminal, and the control command signal is converted into a corresponding intelligent equipment control command signal through the intelligent gateway and then is input into the communication interface module 2 through the external intelligent gateway. And then the communication interface module 2 inputs the control command signal of the intelligent device into the actuator. And the actuator generates a corresponding response signal of the intelligent equipment control command signal after receiving the intelligent equipment control command signal. The response signal of the intelligent device control command signal is transmitted to the external intelligent gateway by the communication interface module 2 and further input into the intelligent control terminal, so that the user of the intelligent electrical equipment can timely obtain the feedback condition of the actuator to the intelligent device control command.
The 485 isolation module 5 is arranged between the communication interface module 2 and the micro control unit 7. On one hand, the intelligent device control command signal is received by connecting the 485 communication wiring end in the communication interface module 2 (RS-485 communication interface) through the 485 signal input/output end, and then the 485 isolation module 5 is connected with the universal asynchronous receiving/transmitting transmitter receiving end of the micro control unit 7 through the universal asynchronous receiving/transmitting transmitter sending end so as to input the intelligent device control command signal into the micro control unit 7. In the process, the 485 isolation module isolates the intelligent device control command signal from the direct current of the intelligent device so as to improve the anti-interference capability of the intelligent device control command signal on electrostatic discharge (ESD) or electromagnetic interference (EMI). On the other hand, the 485 isolation module 5 is connected with the sending end of the universal asynchronous receiving and sending transmitter of the micro control unit 7 through the receiving end of the universal asynchronous receiving and sending transmitter of the 485 isolation module so as to receive the response signal of the intelligent device control command generated by the micro control unit, and then the 485 isolation module 5 is connected with the 485 communication wiring end in the communication interface module 2 (RS-485 communication interface) through the 485 signal input/output end of the 485 isolation module so as to input the response signal of the intelligent device control command into the communication interface 2 (RS-485 communication interface).

On one hand, the micro control unit 7 receives the intelligent device control command signal output by the 485 isolation module 5, performs collision detection, analysis and decision on the signal, and then generates a first execution command and a response signal of the intelligent device control command. On the other hand, the micro control unit 7 receives the electrically isolated dry contact signal output by the opto-isolator input module 6, performs collision detection, analysis and decision on the dry contact signal, and then generates a second execution command. The micro control unit 7 inputs a response signal of the intelligent device control command into the 485 isolation module 5, and the micro control unit 7 also transmits the first execution command and the second execution command to the relay driving module 8. The micro control unit 7 also maintains stable operation of its own system.
The relay driving circuit module 8 converts the first execution command and the second execution command output by the micro control unit 7 into a corresponding relay first driving signal and a corresponding relay second driving signal, respectively. The relay drive circuit module 8 then inputs two relay drive signals to the relay module 9. The first execution command corresponds to the intelligent control command signal, so that the first driving signal of the relay comprises an operation state regulating signal of the actuator external electrical equipment in the intelligent control command signal.
