The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and fig. 3, the intelligent single fire switch with delayed reset of the present embodiment includes a selection circuit, a micro control unit and a relay, where the micro control unit includes a micro control unit circuit, a delayed control circuit and a voltage stabilizing chip; and the output end of the voltage stabilizing chip is connected with the input ends of the micro control unit circuit and the delay control circuit. The voltage stabilizing chip is a low-dropout direct-current voltage stabilizing chip. Wherein, choose low-power consumption reset chip for use, the low quiescent current of uA level can guarantee that single fire switch awaits the opportune moment under the low-power consumption state, avoids lamps and lanterns to appear ghost fire scintillation under the off-state. When the single-fire intelligent switch is powered on in a light-on state, the transferred direct current charges the energy storage capacitor. At this moment, the reset chip resets the wireless intelligent main control MCU, when the capacitor is charged to the time that the wireless intelligent main control MCU can normally work, VCC is greater than a certain level at this moment, the reset signal sent by the reset chip is invalid, and the electric energy stored on the energy storage capacitor enables the wireless intelligent main control MCU to start to be powered on and normally work.

As shown in fig. 2, when power is turned on, the low dropout regulator outputs VCC to the delay start chip. When the C1 of the delay starting circuit is not charged to a set value, a RESET PIN PIN of the delay starting chip outputs a RESET RESET signal to the micro control unit, so that the micro control unit is not started. When the C1 of the delay starting circuit is charged to a set value, the delay starting circuit delays for a period of time, and the RESET PIN PIN of the delay starting chip outputs a signal of normal work to the micro control unit, so that the micro control unit is started normally.
When the voltage stabilizing chip is powered on and the output voltage of the voltage stabilizing chip is lower than the set value of the delay starting circuit, the delay starting circuit outputs a reset signal to the micro control unit, so that the micro control unit is not started.
