Description

Novel language security warning board

The utility model relates to a kind of safety guard, particularly adopts the safety guard of language caution automatically.

As everyone knows, oil depot, the refuelling station, emphasis such as inflammable explosive article warehouse fire prevention unit and place, at every moment all can not adopt a casual attitude for pyrotechnics, except disposing various fire fighting devicies, to carry out strict fire prevention caution for vehicles passing in and out and personnel, domestic once had a kind of language warning sign that adopts the tape loop playback, though can play language, but the life-span of resetting is too short, and tape and magnetic head often rub, and magnetic is lost, sound is more and more littler, player core also lost efficacy easily, and it is uncontrolled to broadcast simultaneously, no car nobody the time also constantly broadcast, the worry that causes the user is with uneasy, can not automatic switch for the daylight lamp of interior dress, use inconvenience, waste of energy is serious.

The purpose of the utility model aims to provide and a kind ofly adopts up-to-date heat to release infrared electronic technology and solidify speech recording and reproducing technology, light control automatically, reliable operation, long service life, novel voice security warning board that automaticity is high.

Technical solution of the present utility model is: this novel voice security warning board is released infrared probe by heat, lighting, light activated element, loudspeaker and speech synthesizer, the speech power amplifier, trigger intermittently, dc supply, the non-attended light light control circuit is formed, heat is released the infrared probe transducing signal and is triggered language generator, language generator output is after the speech power amplifier amplifies, promote Yang Shengqi and play out the caution language, himself resistance of light activated element is determined by extraneous sensitization situation, cooperate the non-attended light light control circuit, switch on or off the lighting power supply, intermittently trigger also intermittently triggers language generator, promote loudspeaker and periodically play the caution language, dc supply provides the direct-current working volts electric current of above-mentioned each circuit.

Below in conjunction with accompanying drawing technical elements of the present utility model is described in further detail.

Fig. 1 is the utility model structured flowchart;

Fig. 2 is the utility model circuit diagram.

Electric theory diagram shown in Figure 1 is as the previous technique scheme is described, and probe, lighting, loudspeaker, light activated element are installed in outside the shell, and other circuit elements devices all are welded on the circuit board.Its circuit structure of the utility model as shown in Figure 2, dc supply is by transformer B, rectifier P ₄, integrated regulator D ₄Be main the composition, language generator is by language reservoir D ₃And resistance R ₂Be main the composition, the speech power amplifier is by integrated circuit D ₅, D ₆Forming the BTl amplifying circuit is main formation, and intermittently trigger is by time base circuit D ₂, diode P ₆, P ₇, resistance B ₃, R ₄, R ₅, capacitor C ₅Constitute, the non-attended light light control circuit is by time base circuit D ₁Be connected into comparison amplifier and Shi Mite trigger circuit, relay J ₁Cooperate photoresistance ZR, lighting to constitute.

Physical circuit connect and circuit analysis as follows: when the power transformer B of dc supply is elementary be connected on civil power after, all circuit are in running order, dc supply output DC12V, DC6V working power, language generator B ₃13 pin pass through capacitor C ₄Be connected to heat and release the output stage of infrared probe 1 or trigger D intermittently ₂3 pin output stages, heat is released in the infrared probe range if any the people, car is arranged through out-of-date, the infrared heat energy that human body and engine produced, can change with moving, meanwhile, heat is released infrared probe and is mapped on the infra-red heat photosensitive elements by interior lens are poly-, is that the noble potential of 16 seconds or 8 seconds removes to trigger language generator thereby export a time, triggers circuit

Be J → C ₄→ D ₃13 pin, language generator D ₃Also can be by trigger D at intermittence ₂3 pin, export a noble potential at regular intervals and go to trigger, intermittently trigger also is to utilize time base circuit NE555, during energized, electric current is through R ₃, R ₅To C ₅Charging, after about a period of time, D ₂2,6 pin current potentials reach about 4V, 10 seconds left and right sides noble potentials of 3 pin output remove to trigger language generator D ₃, while D ₂Put lotus and hold 7 pin to start working, make 2,6 pin current potentials drop to about 2V D ₂Upset, 3 pin are output as zero potential, thereby finish one-period, keep under the power supply situation, and circuit will repeat said process.This, trigger was when not adorning probe at intermittence, made the language control usefulness of regularly broadcasting, generally can, language generator D ₃Then by 9 pin output language signals, through R ₅, R ₇, X ₂, C ₉Behind the wave filter of forming, by C ₃Deliver to D ₅, D ₆The BTL amplifier of forming sends 0-8W power language sound equipment.Additional non-attended light light control circuit is then by time base circuit D ₁(ME555) comparison amplifier that is connected into cooperates relay J with the schmitt trigger circuit ₁Remove to control the electric ballast DZ of exterior lighting light fixture, thereby make daylight lamp work, at D ₁2,6 pin to external photoresistance ZR between the ground, when not being subjected to the light time, internal resistance is bigger, D ₁2,6 pin when current potential rises to 2/3VCC between ground, by 3 pin output earth potential, J ₁Get electric adhesive, DZ starts, and daylight lamp is lighted, and after daybreak, photoresistance is subjected to light, and internal resistance diminishes, D ₁2,6 pin current potentials when dropping to 1/3VCC, 3 pin output noble potential, J ₁Discharge, relay contact disconnects, and daylight lamp extinguishes.

Each integrated circuit model: D ₁, D ₂5 is time base circuit NE555, D ₃Produce language for MOSEL MSSJ/Z1 Taiwan and solidify integrated circuit, D ₄Be integrated regulator 7806, D ₅, D ₆Be integrated circuit TDA2003.

The utility model with heat release infrared, solidify the language recording playback, new technologies such as light, electric ballast fully successfully are applied in the new product automatically, function admirable, element is succinct, anti-interference sampling frequency height, speech fidelity is good, long service life, automaticity height, make this language warning sign be embodied everywhere new meaning, should vigorously promote the use.
