Should following functions be had as intelligent sound control circuit:
1. can in the conducting of realizing circuit under Sound control and cut-off;
2. sending of sound should be many-sided, as footsteps, and object whop etc.;
3. the response time should be more short better.
The higher sound transducer of sensitivity (the design selects Electret condenser microphone MIC) should be selected when selection circuit components and parts for this reason to form the front end of sound control circuit, also spring sensed condition such as sound intensity will be established could must to respond at more than 20DB for this transducer simultaneously.Intermediate ends adopts trigger to form, and utilize trigger not touch and do not send out, hairtrigger feature goes to promote lighting circuit work, and the selection of trigger also should be selected highly sensitive, response time short trigger as d type flip flop, JK flip-flop etc.
The cardinal principle of light-operated circuit: utilize the light-sensitive element feature that impedance changes with the change of intensity of illumination, go the power controlling the signal of telecommunication, again by transducer by the electrical signal transfer of change to trigger, as long as electrical signal intensity acquires a certain degree and trigger flip-flops is made its ON operation.
In such circuit design, also very high to the requirement of circuit components, especially light-sensitive element.Light-sensitive element is the core of light-operated circuit functional realiey, must ensure the accurate, stable of its parameters.
Optical semiconductor photosensitive elements is the photoelectric photoelectric conversion sensor of based semiconductor, also known as photoelectric sensor.Adopt photoelectric technology can realize contactless, remote, measure fast and accurately, therefore optical semiconductor photosensitive elements is also commonly used to other physics or the chemical quantity that indirect inspection can convert light quantity to.Optical semiconductor photosensitive elements is divided into guide type and photovoltage type (see electro-optical pickoff) by photoelectric difference.Guide type and photo resistance are a kind of semiconductor homogeneous textures.
The major parameter of optical semiconductor photosensitive elements and characteristic have sensitivity, detectivity, illumination rate, light characteristics, voltage-current characteristic, spectral characteristic, time and frequency response characteristic and temperature characterisitic etc., and they determine primarily of material, Structure and energy.Optical semiconductor photosensitive elements is widely used in accurate measurement, optical communication, computing technique, shooting, night vision, remote sensing, guidance, robot, quality examination, security alarm and other measurements and control device.Common light-sensitive element has: photo resistance, photodiode, phototriode etc.
What is called is light-operated is exactly the impedance difference utilizing light-sensitive device to present different light, and when photo resistance is by illumination, resistance reduces.Amplifier in the same way input end is low level; When illumination is more weak, resistance increases, and amplifier in the same way input is high level.Fainter current signal, after voltage follower, is amplified to the electric current that single-chip microcomputer can identify by the output signal of light-operated circuit, then by amplifier output, the signal after amplification is passed to the P1.6 mouth of single-chip microcomputer.
It is very extensive that LED matrix is employed, such as street lamp, illuminating lamp between corridor, and some also based on sound induction, but does not consider light intensity, still bright light by day or when sensing sound under well-lighted situation.
In addition, existing LED matrix substantially all can not Automatic adjusument brightness, and user experience is not high.
