Detailed Description
One embodiment of the present invention is described in detail with reference to fig. 2, but does not limit the claims of the present invention in any way.
As shown in fig. 2, a repeatedly triggered acousto-optic control circuit includes a light detection circuit, a sound detection circuit, a lamp driving circuit, a first AND gate AND1, a second AND gate AND2, a non-gate INV, a first timer, a second timer, a D trigger, AND an RS trigger;

the D input end of the D trigger is connected with a high level;
the output end of the first AND gate is respectively connected with the CP input end of the D trigger and the input end of the NOT gate INV;
an output terminal of the not gate INV is connected to a second input terminal of the second AND gate AND2,
the output end of the second AND gate is respectively connected with the enabling input end of the first timer, the enabling input end of the second timer and the S input end of the RS trigger;
the output end of the first timer is connected with the CLR input end of the D trigger;
the output end of the second timer is connected with the R input end of the RS trigger, and the timing time of the second timer is smaller than that of the first timer;
the Q output end of the RS trigger is connected with the enabling input end of the sound detection circuit;
the output end of the lamp driving circuit is connected with the controlled lamp.
In the invention, the sound detection circuit and the light detection circuit are all detection circuits commonly used in the prior art, the specific circuit structure is not repeated, and the basic logic functions of the sound detection circuit and the light detection circuit are as follows:
the sound detection circuit: when the enable input end of the sound detection circuit inputs a low level, the sound detection circuit is started and works, and when sound is detected, the output signal of the sound detection circuit is a high level; when the enable input of the sound detection circuit inputs a high level, the sound detection circuit is turned off.
Light detection circuit: when the enable input end of the light detection circuit inputs low level, the light detection circuit is started and works, and when no light is detected, the output signal of the light detection circuit is high level; when the enable input end of the light detection circuit inputs a high level, the sound detection circuit is closed, and the output is high level when the sound detection circuit is closed.
The first timer inputs high level effectively, when the signal of the input enabling input end is high level, the first timer starts working, and when the timing is finished, the output is high level; when the signal at the input enable input is low, the timer is turned off.
The second timer inputs high level effectively, when the signal of the input enabling input end is high level, the second timer starts working, and when the timing is finished, the output is high level; when the signal at the input enable input is low, the second timer is turned off.
The working principle of the invention is as follows:
when no sound exists, the light detection circuit AND the sound detection circuit both output high level, the output of the D trigger Q output end changes to high level, the light detection circuit is closed, when the sound disappears, the output of the sound detection circuit changes to low level, the output of the first AND gate AND1 changes to low level, the output of the second AND gate AND2 changes to high level, the output of the RS trigger Q output end changes to low level, the sound detection circuit is closed, AND the first timer AND the second timer start timing. When the second timer is finished, the output of the RS trigger becomes high, the sound detection circuit starts to work, and at the moment, if sound exists, the output of the sound detection circuit is high, and the first timer and the second timer are re-timed.
The second timer counts a short time compared to the first timer. When the first timer and the second timer are both timed, the sound detection circuit is turned off; when the second timer finishes timing, the sound detection circuit works when the first timer finishes timing; when the first timer counts, the light detection circuit is always turned off whether the second timer counts or not.
When the output becomes high level and the D trigger becomes low level after the first timer is finished, the light detection circuit and the sound detection circuit start to work, and the circuit enters a standby state.
In summary, the invention has the following advantages:
the repeatedly triggered acousto-optic control circuit has a simple structure, can realize that the lamp driving circuit keeps driving the lamp by continuously triggering the sound detection circuit under the condition of keeping the lamp on-line without using micro controller parts such as MCU (micro controller Unit) and the like, and solves the problem that the existing acousto-optic control circuit can only trigger on again after the lamp is extinguished when the lamp is required to be maintained for illumination in a longer period of time, thereby greatly improving the convenience of users and prolonging the service life of the lamp.
