The central processing module 300 includes a central processing chip 310, a first resistor R1 and a first capacitor C1, the central processing chip 310 is connected to one end of the first resistor R1, the central processing chip 310 is connected to one end of the first capacitor C1, the other end of the first resistor R1 is connected to the sound acquisition module 100, the other end of the first capacitor C1 is grounded, and one end of the first capacitor C1 is further connected to the illumination acquisition module 200.
For example, the controlled device 30 is connected to the power supply 20 through the acousto-optic controlled delay switch 10, the acousto-optic controlled delay switch 10 can detect the external sound signal and the illumination signal, after detecting the external sound signal and the illumination signal, the first capacitor C1 can discharge through the first resistor R1, the discharge speed of the first capacitor C1 is affected by the resistance of the first resistor R1, the electric quantity of the first capacitor C1 is affected by the illumination signal, the voltage across the first resistor R1 is affected by the sound signal, and at the same time, the central processing chip 310 can process the discharging speed of the first capacitor C1 and the voltage across the first resistor R1, the controlled device 30 is controlled, so that the first capacitor C1 and the first resistor R1 can process the detected external sound signal and the light signal, thereby controlling the connection state between the controlled device 30 and the power source 20.
in particular, when the illumination signal is strong and there is a sound signal, the voltage value across the first capacitor C1 is higher than one third of the threshold voltage of the threshold port of the central processing chip 310, so that a closed loop is not formed between the controlled device 30 and the power supply 20.
As an embodiment, in order to filter the situation that the duration of the sound signal is less than 2 seconds, the resistance of the first resistor R1 may be adjusted so that the voltage across the first capacitor C1 is a certain discharging current, if the voltage across the first capacitor C1 is discharged for 2 seconds and the voltage across the first capacitor C1 is still higher than the threshold voltage of the input central processing chip 310, then the controlled device 30 may not form a closed loop with the power supply 20, and if the duration of the sound signal is higher than 2 seconds, then the voltage across the first capacitor C1 is discharged after 2 seconds, the voltage across the first capacitor C1 is lower than the threshold voltage of the input central processing chip 310, and a closed loop is formed between the controlled device 30 and the power supply 20, thereby, the sound signal with the duration less than 2 seconds may be filtered, and it is understood that the sound-light controlled delay switch 10 may be adjusted according to actual situations, so that the sound and light controlled delay switch 10 can filter the condition that the duration of the sound signal is lower than any setting, thereby realizing the protection of the controlled device 30, avoiding the false start and ensuring the safe work of the controlled device 30.
In particular, the stronger the illumination signal is, the larger the charging current of the first capacitor C1 is, and the longer the corresponding set-point time is, the stronger the suppression capability of the acousto-optic controlled delay switch 10 on the sound signal along with the stronger the illumination signal can be realized.
