The invention can be applied to places such as corridors, washrooms, basements, staircases, garages and the like. Under the normal condition of inserting of commercial power supply, auto-induction, automatic photometry utilize photosensitive to detect, and highlight and day under do not respond to, but weak light and night response. When the mains supply cannot work normally due to an earthquake, a fire or other events, the fire-fighting power supply can provide continuous power supply, so that the lamp is always on, and the emergency can be evacuated in time. And fire control power supply part and commercial power supply part are complete isolation, even because operating personnel's mistake leads to commercial power supply and fire control power supply to insert simultaneously, also can only be preferred by fire control power supply part work. In addition, the load range is wide, and various loads such as LED lamps, energy-saving lamps, tungsten filament lamps, exhaust fans and the like can be used.
The working principle of the invention is as follows:
when the mains supply is connected and the fire-fighting power supply is not connected, the electric heater is powered on, the fire-fighting lamp (exemplified by fire fighting and the like in the embodiment) is on, namely the OUT pin is high in output, then the one-way thyristor T1 is conducted, and reverse leakage current exists on the diode D1, so that the two-way thyristor SCR is turned on; the current direction of lighting the fire fighting lamp at this time is: l → F1 → D1A1 → SCR → D1D1 → NTC → LOUT. The direction of the supply current from the dc power supply unit to the main control unit (the single chip in this embodiment): l → F1 → D1a1 → T1 → D3 → D6 → U1 → (VDD), thereby supplying power to the rear one-chip microcomputer. At this time, CH _ L detects the high level, and singlechip control EN _ XF foot output is high, because the fire control power supply is not connected, this part of circuit need not consider, CH _ XF4 foot detects high.
After a period of time delay, the single chip microcomputer controls the EN _ XF pin to output low, and the CH _ XF4 pin is still detected to be high. At this time, the output of the singlechip control out pin is low, T1 is cut off, thereby SCR is cut off, and the fire-fighting lamp is extinguished. The power supply current direction of the singlechip is as follows: l → F1 → D1a1 → R19 → Q1 (current flows through R21 and R22, making transistor Q1 conductive by the action of zener diode D4) → U1 → (VDD).
When a person enters the induction area, the lamp can be immediately turned on, and when the person leaves the induction area, the lamp can be turned off after a set time is delayed.
When the mains supply is not connected and the fire-fighting supply is connected, the fire-fighting lamp is normally on after being powered on. The EN _ XF3 foot does not have the electricity and inserts, can regard as the low level to the output nonconducting (3 feet and 4 feet are disconnected) of opto-coupler U3, 4 feet electric potentials are high, can open one-way thyristor T2, open two-way thyristor SCR1 afterwards, make the fire control lamp bright often. The current direction is XF → F2 → D1A2 → SCR1 → D1D2 → LOUT 1. Because the mains supply is not connected, the singlechip does not work without power supply, and the functions of photosensitive induction and human body induction cannot be used.
When the mains supply and the fire protection supply are both connected, after the output of an OUT pin is low, the single chip microcomputer controls EN _ XF to be low all the time, namely the fire protection supply is used as a power supply of a load all the time; after T2 is conducted, a node of R24 and R25 is at a high level, and through D8 and R33, an input end of an optocoupler U4 is conducted (a pin 1 is connected with a pin 2), so that an output end is conducted (a pin 3 is connected with a pin 4), a CH _ XF pin detects low, and the single chip microcomputer enables an OUT pin to forcibly output low; at the moment, the mains supply is only responsible for supplying power to the singlechip.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
