The present invention discloses an overheat protection method, device and porch heating device, which relates to the temperature control field. The porch heating device includes a processor, a heater and a temperature control module. After the processor detects that the connection between the heater and the power supply is disconnected, it determines whether the connection is restored after a first preset duration. If it is not restored, the heater is directly locked; if it is restored, the number of overheat fault occurrences is recorded once. When the number of overheat fault occurrences is greater than the preset fault number, the heater is also directly locked. After the heater is locked, it remains in the shutdown state, and the number of overheat fault occurrences is cleared after the heater is locked. By detecting the change in the connection state between the heater and the power supply, the heater is locked when it is detected that the connection is disconnected for a period of time or when there are frequent on-off operations. On the premise of ensuring overheat protection for the porch heating device, frequent on-off operations of the temperature control module are avoided, and further, the service life of the temperature control module and the porch heating device is prevented from being reduced due to frequent on-off operations.

The utility model relates to the technical field of illumination, in particular to a green and energy-saving induction type porch lamp for building mansions. The technical problem is that in the operation process of an induction type porch lamp, if the porch lamp only adopts an infrared switch, the porch lamp can be triggered only when people walk in due to a relatively narrow induction area, and if the porch lamp only adopts a voice operated switch, sometimes, the porch lamp cannot be triggered due to too light footstep sound of pedestrians, so that the user experience is poor. According to the technical scheme, the green and energy-saving induction type porch lamp for building the mansion comprises an illumination assembly. By arranging the angle adjusting mechanism, the environment brightness detection mechanism and the double pedestrian sensing mechanism, the illumination angle of the device can be more flexible, the lamp is intelligently controlled to only illuminate at night, meanwhile, the advantages of infrared induction and sound wave dry sound are combined, and the illumination effect is better. The large induction range of the lamp is guaranteed, and the problem that equipment cannot provide illumination in time due to the fact that the feet of a user are light is solved.

This invention provides a threshold adaptive leading-edge blanking method for switching power supplies. It establishes an adaptive leading-edge blanking control loop, allowing the voltage threshold to adaptively change with load size or PVT influence through threshold adaptation. This invention enables adaptive leading-edge blanking and adaptive threshold selection. It continuously adjusts suitable stability conditions to adapt the voltage threshold, unlike traditional adaptive leading-edge blanking modules. The system automatically finds the optimal balance between anti-interference capability and detection sensitivity at any given time, significantly improving the robustness and reliability of the switching power supply under various complex operating conditions. Adaptive blanking shortens the physical dead zone, and the adaptive threshold immediately provides optimal detection sensitivity after the dead zone ends, thus achieving near-dead-zone-free high-reliability overcurrent protection. This invention also eliminates race conditions, reducing glitches in digital modules and improving the circuit's anti-interference capability.
