[0002] With the advent of the Internet of Things era, more and more electrical appliances have intelligent control functions, including lighting fixtures, fans, electric curtains, clothes drying racks, etc. At present, they are mainly controlled by remote controls or mobile phones, but there is a problem, that is, it is difficult to control them at the same time with the mechanical switch on the wall. For example, when the mechanical switch is disconnected, the device has no power supply, and it is even more impossible to control it through remote control or mobile phones. The mechanical switch on the wall must be sacrificed and the AC power supply circuit must be short-circuited directly before it can be used, or the switch must be turned on before remote control or mobile phone control, which is very inconvenient and has become an obstacle in the process of Internet of Things for electrical appliances. Therefore, how to use the mechanical switch on the wall for local manual control while being compatible with other intelligent control methods is a problem that must be solved. Summary of the invention

[0008] The drive control circuit includes a data processing circuit and an output drive circuit, the data processing circuit is electrically connected to the output drive circuit, the data processing circuit is electrically connected to the loop gap pulse detection circuit, and the output drive circuit is electrically connected to the controlled device.
[0009] The loop gap pulse detection circuit may be a voltage detection circuit, a current detection circuit, or an inductive coupling detection circuit.
[0010] The controlled equipment may be lighting equipment, electromechanical equipment, audio-visual equipment or HVAC equipment.
[0011] The first control state or the second control state or the third control state or the fourth control state or the fifth control state or the sixth control state output by the driving control circuit to the controlled device respectively can be light on, light off, motor forward rotation, motor reverse rotation, motor pause, audio playback, pause playback, HVAC start, HVAC stop, timed start, timed stop, light source brightness, motor speed, sound source volume, heat source heat or duration range.
[0012] The loop gap pulse detection circuit and the drive control circuit can be integrated into an integrated chip or module with the functions of detecting the gap pulse signal of the short-term change of the AC signal characteristics, and processing the level pulse signal data and driving control.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an AC circuit gap pulse control device includes a circuit gap pulse detection circuit 1, a drive control circuit 2 and a controlled device 3, wherein the circuit gap pulse detection circuit 1 is electrically connected to the drive control circuit 2, and the drive control circuit 2 is electrically connected to the controlled device 3; the circuit gap pulse detection circuit 1 converts the gap pulse signal with a short-term change of AC signal characteristics in the circuit into a corresponding level pulse signal and provides it to the drive control circuit 2; after receiving the level pulse signal, the drive control circuit 2 implements corresponding state control of the controlled device 3.
[0025] The short-term changing gap pulse signal detected by the loop gap pulse detection circuit 1 is a negative half-wave missing gap pulse, a positive half-wave missing gap pulse or a full-wave missing gap pulse, and is converted into a first level pulse, a second level pulse or a third level pulse respectively.
[0026] When the drive control circuit receives two groups of first level pulses, two groups of second level pulses or two groups of third level pulses provided by the loop gap pulse detection circuit within the specified time period T1, it outputs the state control of the first control state, the second control state or the third control state to the controlled device respectively.
