In addition, the load range is wide, and various loads such as LED lamps, energy-saving lamps, tungsten lamps and exhaust fans can be used.

The working principle of the present utility model is as follows:

When the mains power supply is connected, and the fire fighting power supply is not connected, the heater is powered on, and the fire fighting light (for example, firefighting, etc. in this embodiment) is on, that is, the output of the OUT pin is high, and then the one-way thyristor T1 is turned on, and the diode D1 is on There is a reverse leakage current, thus turning on the triac SCR; at this time, the current direction of lighting the fire lamp is: L→F1→D1A1→SCR→D1D1→NTC→LOUT. The power supply current direction of the DC power supply unit to the main control unit (this embodiment is a single chip microcomputer): L→F1→D1A1→T1→D3→D6→U1→(VDD), thereby supplying power to the subsequent single chip microcomputer. At this time, CH_L detects a high level, and the single-chip microcomputer controls the EN_XF pin to output high. Because the fire power supply is not connected, this part of the circuit does not need to be considered, and the CH_XF4 pin detects a high level.

After a period of delay, the single-chip microcomputer controls the EN_XF pin to output low, and the CH_XF4 pin is still detected as high. At this time, the single-chip microcomputer controls the output of the out pin to be low, and T1 is turned off, so that the SCR is turned off, and the fire light is turned off. The direction of the power supply current of the microcontroller: L→F1→D1A1→R19→Q1 (the current flows through R21 and R22, and the transistor Q1 is turned on by the action of the Zener diode D4)→U1→(VDD).

When a person enters the sensing area, the light will be turned on immediately, and after leaving the sensing area, the light will be turned off after a set time delay.

When the mains power supply is not connected, and the fire protection power supply is connected, after power-on, the fire-fighting light is always on. The EN_XF3 pin has no electrical connection, it can be regarded as a low level, so the output end of the optocoupler U3 is not conducting (pins 3 and 4 are not connected), and the potential of pin 4 is high, which can turn on the one-way thyristor T2, Then turn on the triac SCR1, so that the fire light is always on. Current direction: XF→F2→D1A2→SCR1→D1D2→LOUT1. Because the mains power supply is not connected, the single-chip microcomputer does not work without power supply, and cannot use the photosensitive response and human body sensing functions.

When both the mains power supply and the fire protection power supply are connected, after the output of the OUT pin is low, the single-chip microcomputer controls EN_XF to be low all the time, that is, the fire protection power supply is always used as the power supply for the load; after T2 is turned on, the R24 and R25 nodes are high power Flat, through D8 and R33, the input end of the optocoupler U4 is turned on (pin 1 and 2 are connected), so the output end is turned on (pin 3 and 4 are connected), the CH_XF pin is detected low, and the microcontroller makes the OUT pin forcibly output Low; at this time, the mains power supply is only responsible for supplying power to the microcontroller.

The examples of this specific embodiment are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore: all equivalent changes made according to the structure, shape and principle of the present invention are not It should be covered within the protection scope of the present invention.
