[0036] The power module includes one or both of zero fire power module and single fire power supply module, and the power module is connected with microprocessor 5 and communication module 6.

[0037] The communication module 6 includes wired communication module and wireless communication module, and the wireless communication module includes one or a plurality of combinations of 2.4G wireless module, LORA module and Bluetooth module.

[0038] The microprocessor 5 is connected with storage chip 10 by I2C serial communication;

[0039] The input of microprocessor 5 is connected with key module 11.

[0040] The key module 11 includes a plurality of touch keys and key chips, and the plurality of touch keys are connected with the input of the key chip, and the output of the key chip is connected with the microprocessor 5.

[0041] The single fire power supply module includes switch circuit 801 and single fire power supply chip 802, the switch circuit 801 includes first MOS tube and second MOS tube, the S pole of the first MOS tube and the second MOS tube is grounded, the D pole of the first MOS tube and the second MOS tube is electrically connected with the fire line respectively, the G pole of the first MOS tube and the second MOS tube is connected with single fire power supply chip 802, and the output of the single fire power supply chip 802 is connected with microprocessor 5 and communication module 6.

[0042] The zero fire power module includes rectifier module 701 and voltage conversion chip 702, the rectifier module 701 is connected with zero line and fire line, the output of the rectifier module 701 is connected with voltage conversion chip 702,

[0043] The output of the voltage conversion chip 702 is connected with microprocessor 5 and communication module 6.

[0044] The microprocessor 5 is electrically connected with watchdog circuit 12.

[0045] In this embodiment, the microprocessor 5 is an STM32 microcontroller, the single-wire power chip 802 is an XD303A chip, the communication module 6 is a LoRa module, and the intelligent control device is a remote control equipped with a LoRa module. The on / off switch 9 includes an optocoupler and a relay. The output terminal of the microprocessor 5 is connected to the optocoupler, and the output terminal of the optocoupler is connected to the relay. The normally open contact of the relay is connected to the control line 4 and the neutral line, and the normally closed contact of the relay is connected to the neutral line and the phase detection module 3. The phase detection module 3 uses an XD3023 chip.

[0046] During wired operation, if mechanical switch 1 is closed and the relay coil of on / off switch 9 is de-energized, current flows through the live wire to the neutral wire, illuminating lamp 2. When mechanical switch 1 is opened, the circuit of lamp 2 is broken, and lamp 2 goes out. If mechanical switch 1 is opened, its contacts connect to control line 4, sending a lighting control signal to microprocessor 5 via button module 11. Microprocessor 5 then activates the optocoupler, energizing the relay coil.

If the neutral wire is missing, the microprocessor 5 de-energizes the relay coil, and current flows through the live wire to the neutral wire, illuminating the lighting lamp 2. If both the live and neutral wires are missing, the microprocessor 5 energizes the relay coil, closing the normally open contact and opening the normally closed contact, allowing current to flow through the control line 4, illuminating the lighting lamp 2.

[0048] Conversely, if lighting 2 needs to be turned off, a light-off control signal is sent via remote control. The detection module 3 detects the status of mechanical switch 1. When mechanical switch 1 is closed, microprocessor 5 energizes the relay coil, causing the normally closed contact of the relay to open, thus turning off lighting 2. When mechanical switch 1 is connected to control line 4, microprocessor 5 de-energizes the relay coil, resetting the normally open contact of the relay, thus turning off lighting 2.

The single-wire power supply chip 802 turns on the first and second MOSFETs when the voltage waveform is within ±30V (±30V is an approximate value; the actual value varies between manufacturers), connecting the two ends of the live wire to form a loop. Current flows through the single-wire power supply chip 802, and the CIN pin of the single-wire power supply chip 802 stores power through external circuitry and outputs a DC 3.3V current to power the microprocessor and communication module 6.
