[0056] The present invention is further described below with reference to specific cases:

[0057] Specific case device structure, such as Figure 1 As shown, including:

[0058] Slogan switching functional unit and lighting control functional unit.

[0059] 1) Slogan switching functional unit, including: optocoupler module, MCU main control module, 232 communication module, power supply module.

[0060] The optical coupler module is used to detect the ETC control signal of AC220V;

[0061] The MCU main control module is used to process the slogan control function, and finally sends the required control characters to the LED display screen according to the AC220V signal state that controls the state of the ETC display screen;

[0062] The 232 communication module is used for communication between the MCU main control module and the LED display screen;

[0063] The power supply module is used to provide 3.3V DC power supply for the circuit.

[0064] 2) Lighting control functional unit, including: light control switch module, optocoupler module, field effect tube module, lighting control switch module, power supply module.

[0065] The light-controlled switch module is used to determine whether it is day or night to control whether the light is on or off;

[0066] The optical coupler module is used to detect the on / off of the AC220V control signal output by the optical switch. The output signal of the optical coupler is filtered by RC to control the on / off of the NMOS tube to control the on / off of the DC power supply of the LED lamp. By adopting this electronic switch, the switch life is extended and the reliability of the circuit is improved.

[0067] The field effect tube module is used to control the on and off of DC12V and DC24V required for lighting;

[0068] The lighting control module is used to control the on and off of the lights;

[0069] The power supply module is used to provide the required DC12V power supply.

[0070] The MCU main control module has an MCU based on GD32E230C8T6, and the optical coupling on-off quantity and the slogan switch switching quantity can be converted into a communication protocol recognizable by the main control board by modifying the program therein;

[0071] The 232 communication module has an input interface and an output interface socket, which is located in the upper left corner of the rectangular circuit board and is connected to the host computer and the main control board respectively through the RS232 communication line;

[0072] The power supply module has a voltage conversion circuit, which converts AC220V voltage into DC12V voltage, and converts DC12V voltage into DC3.3V voltage.

[0073] Among them, the optocoupler module and MCU module of the slogan switching function unit are as follows Figure 2 The above is specifically used for:

[0074] AC220V is connected to the input end of the optocoupler. When there is no AC220V ETC control signal, the optocoupler output is in the cut-off state, and the optocoupler outputs a 3.3V voltage through a pull-up resistor, which is a high-level signal.

[0075] When there is an AC220V ETC control signal, the AC220V voltage converts the AC current into a unidirectional pulsating current through the current limiting resistor and diode, driving the optocoupler to conduct. The capacitor at the output end of the optocoupler filters the output voltage, making the output voltage smoother. The pull-up resistor makes the optocoupler output a low level, which is detected by the MCU. The MCU sends the required control characters to the LED display based on the high and low level signal changes of the optocoupler and the high and low level changes of the slogan switch.

[0076] The optocoupler module and field effect tube module of the lighting control functional unit are as follows: Figure 3 As shown, it is used for:

[0077] AC220V is connected to the input of the optocoupler through a series resistor and a rectifier diode. When there is no AC220V control signal output by the optical switch, the optocoupler output is in the cut-off state, and the optocoupler outputs a 12V voltage through the pull-up resistor, which is a high-level signal. This high level turns off the switch circuit composed of two-stage NMOS tubes. The use of two-stage NMOS tubes makes the shutdown more reliable and prevents leakage current caused by incomplete shutdown. The output of the first-stage NMOS tube has a resistor voltage divider network, and the turn-on voltage of the second-stage NMOS tube can be set according to the resistance value.

[0078] When there is an AC220V control signal output by the optical switch, AC220V converts the AC voltage into a unidirectional pulsating current through the current limiting resistor and diode, driving the optocoupler to turn on. When the optocoupler is turned on, the pull-up resistor causes the optocoupler to output a low level. This low level turns on the switch circuit composed of two-stage NMOS tubes, and adds +12V and +24V voltages to the LED lamp. The capacitor and resistor at the output end of the optocoupler perform RC filtering on the output voltage to make the output voltage smoother, ensuring that the NMOS tube is reliably turned off and cut off.

[0079] Using this electronic switch instead of a relay eliminates the drawbacks of relay contacts being easily adhered and damaged by heat, prolongs the life of the switch, and improves the reliability of the circuit.
