Description
Technical field
The invention belongs to electric power application, relate to a kind of voice message enclosure pile.
Background technology
During distribution site operation, sometimes working-yard is positioned at road side or populated area, is caused danger, for this dangerous point to prevent personnel or vehicle in unwitting situation by time below operation field, needing, safety is around set at the construction field (site) and covers fence, and send special messenger to guard.Such as, but at some by extreme terrain region, clearly can not play warning function during road bend, also have in populated area, surrounding can not be looked after by guard sometimes completely, has non-working person and goes forward to surround and watch.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, develop sound prompt device during a kind of distribution site work, be contained in original fence pile pipe, when there being non-working person close to fence, just can send prompt tone " to halt; Keep Clear-High Voltage ", but just remind non-working person's operation field beyond this point at any time.
Technical scheme of the present invention is as follows:
Voice message enclosure pile, comprise fence pile pipe 1, enclosure pile base 2, safe shroud card 3, fence pile pipe 1 has small holes 4, be provided with photosensitive sound prompt device 5 in fence pile pipe 1, photosensitive sound prompt device 5 leaves black photosensitive window 6 after the small holes 4 in fence pile pipe 1 being sealed;
Photosensitive sound prompt device 5 comprises photo-sensitive cell RL, one end of photo-sensitive cell RL is also connected with electric capacity C1 after resistance R1, one end of electric capacity C1 and R2 is also connected with the base terminal of transistor VT after connecing, the other end of resistance R1 also connects one end of speech IC A after connecing the emitter of transistor VT, the trigger end TG of speech IC A one end of connecting resistance R3 are connected with the collector of transistor VT, the other end of photo-sensitive cell RL the other end of connecting resistance R2 are connected with the positive pole of power supply G with after the other end of resistance R3, two pins of external oscillator R4 are respectively with speech IC A's
Two pins are connected, the another one pin of external oscillator R4 is also connected with the common port of photo-sensitive cell RL, resistance R2, resistance R3 after connecing one end of decoupling capacitor C2, loudspeaker is connected to the output terminal of speech IC A, is connected the negative pole of power supply after the other end of decoupling capacitor C2 is connected with one end common port of resistance R1, the emitter meeting transistor VT, speech IC A.
Photo-sensitive cell photoresistance RL corresponds to the small holes 4 in fence pile pipe 1 in the position of photosensitive sound prompt device 5.
Small holes 4 is 1m with the distance of enclosure pile base 2.
Transistor is 3DG8 type silicon NPN low-power transistor, currentamplificationfactorβ >120.
Power supply G is three joints No. 7 dry cells.
Loudspeaker B is 8 Ω, 0.25W small moving-coil loudspeakers.
Photosensitive sound prompt device 5 voice message language is " halt, Keep Clear-High Voltage ".
Principle of work of the present invention is when having non-working person through photo-resistor RL, during the front of black photosensitive window, the sudden change of light detected by surrounding and RL thereof can be caused, so RL two ends photoelectricity resistance increases suddenly, thus cause the positive terminal current potential of capacitor C1 to reduce suddenly, the bias current of transistor VT is mainly through the reverse charging device electric current of resistor R1 formation C1, and make the reverse-biased cut-off of VT, its collector exports positive pulse (>=1/2
u dD) trigger pip.So speech IC A is by triggering work.Its output terminal OUT1, OUT2 export " halt, Keep Clear-High Voltage " phonetic speech power electric signal of storage in a time, directly promote loudspeaker B sounding.Human body is by after RL front, and RL recovers stable low-resistance value, and battery G is charged to the quick forward of C1 by RL and VT emitter junction, and in order to detect after human body next time, triggering voice circuit is ready again.
Advantage of the present invention is easy for installation, simple to operate, and reliability is strong; Low maintenance rate, price economy, easy maintenance, long service life; Closure is good; Use special airtight technology, sound prompt device can not affect by weather, rainwater.

In figure, fence pile pipe 1, enclosure pile base 2, safe shroud card 3, small holes 4, photosensitive sound prompt device 5, black photosensitive window 6, safe shroud 7, voice message enclosure pile 8, voice message enclosure pile 9, voice message enclosure pile 10, voice message enclosure pile 11.
Embodiment
embodiment:
Voice message enclosure pile of the present invention, comprise fence pile pipe 1, enclosure pile base 2, safe shroud card 3, fence pile pipe 1 has small holes 4, be provided with photosensitive sound prompt device 5 in fence pile pipe 1, photosensitive sound prompt device 5 leaves black photosensitive window 6 after the small holes 4 in fence pile pipe 1 being sealed;
Photosensitive sound prompt device 5 comprises photo-sensitive cell RL, one end of photo-sensitive cell RL is also connected with electric capacity C1 after resistance R1, one end of electric capacity C1 and R2 is also connected with the base terminal of transistor VT after connecing, the other end of resistance R1 also connects one end of speech IC A after connecing the emitter of transistor VT, the trigger end TG of speech IC A one end of connecting resistance R3 are connected with the collector of transistor VT, the other end of photo-sensitive cell RL the other end of connecting resistance R2 are connected with the positive pole of power supply G with after the other end of resistance R3, two pins of external oscillator R4 are connected with two pins of speech IC A respectively, the another one pin of external oscillator R4 and after connecing one end of decoupling capacitor C2 with photo-sensitive cell RL, resistance R2, the common port of resistance R3 is connected, loudspeaker is connected to the output terminal of speech IC A, the other end of decoupling capacitor C2 and resistance R1, connect the emitter of transistor VT, the negative pole of power supply is connected after one end common port of speech IC A is connected.
