Dual-purpose infrared induction voice message nameplate and its operational approachTechnical field
The present invention can record for the nameplate of indoor and outdoor power transformation electric operation safety prompt function with one kind is related to, and can play cuing voice automatically dual-purpose infrared induction voice message nameplate and its operational approach.
Background technology
At present, the word of the safety nameplate in electric substation's (station) and the warning function of pattern are limited, when working near safety nameplate, easily ignore the content of safety nameplate, substation equipment maintenance and repair personnel should meet corresponding safe distance in service work to live part, and fence is arranged around live part and nameplate is hung.
The content of the invention
The present invention is when maintainer meets corresponding safe distance in service work, guarantee personal safety, the nameplate should have eye-catching suggesting effect, can't see in maintainer (be detectable, adopt a casual attitude or thought is lost vigilance) exceed safety range apart from when, alarm can be sent for reminding the dual-purpose infrared induction voice message nameplate and its operational approach of maintainer.
The present invention solves technical problem and adopts the following technical scheme that：Dual-purpose infrared induction voice message nameplate of the present invention and its operational approach, including nameplate, strength Magnetitum, infrared induction voice broadcast module, suppending hole and suspension line；It is characterized in that：The nameplate is the cuboid that rigid plastics make, nameplate front upper portion and lower end be respectively arranged with literal field and picture region, the centre position of nameplate is provided with infrared induction voice broadcast module, the centre position at four edges in the back side of nameplate is provided with the strength Magnetitum of circle, the upper end of nameplate two, corner location is provided with suppending hole, suspension line is provided with suppending hole, snak link is installed additional on suspension strop.
Further, the infrared induction voice broadcast module includes the speech electronic module that speech chip U2 and its peripheral components are constituted；The peripheral components include the loudspeaker LS1 for being arranged on the infrared detection device with infrared thermal release electric process chip U1 as core of speech chip triggering end, light shutter device and being arranged in speech chip output loop；The infrared probe being respectively arranged with the front centre position of nameplate in photographic hole, vocal hole, and the infrared circuit；The speech chip U2 adopts read-write chip I SD1810, and in the side of nameplate LED, S1 recording switch, S2 on and off switch and recording jack are respectively arranged with, and is accordingly equipped with the pluggable mike in recording jack for recording.
Further, infrared thermal release electric process chip U1 adopts BISS0001 chips, is that, with direct current 9V cell powers, related technical parameter is：
Running voltage：DC9V；
Level is exported：Someone's 3V high level, unmanned 0V low levels；
Sensing angle:110 degree；
Quiescent current:Less than 40 μ A；
Distance of reaction：4～5M；
Time delay is set as 0.5 second；
Triggering mode:Adjust not repeat；
Sensing element RE200B and Fresnel Lenses are used cooperatively；
The function of speech chip ISD1810 is typing and plays caution sound, and associated technical parameters are：
Running voltage：DC3.2V；
Quiescent current：Less than 10 μ A；
Operating current：25mA；
Record length：12S；
Output：3.5W.
Operational approach is：
On the equipment of maintenance required for nameplate is pasted onto by strength Magnetitum, on the equipment that page is keeped in repair required for nameplate being hung over by suspension line；In the course of the work, by closing S1 recording switch typing caution sounds, now LED is bright, and S1 recording switch is unclamped after the completion of recording；When the infrared probe of infrared detector part detect someone near when, when the photoconductive resistance R1 of light shutter device has detected change in optical signal, the PE terminals of speech chip U2 are high potential, play caution sound.
Compared with the prior art, the present invention has the beneficial effect that：
1st, the present invention can experience the close of human body in certain scope, and actively be pointed out in the way of voice, it is to avoid charging equipment and maloperation are touched in personnel's false touch, drastically increase safety in utilization.
2nd, the present invention can the related voice messaging of repeated taping as needed, be widely used in becoming various places in station.
3rd, present configuration is simple, be easily achieved.

Specific embodiment
According to Fig. 1-Fig. 4, dual-purpose infrared induction voice message nameplate of the present invention, and its operational approach, including nameplate 1, strength Magnetitum 2, infrared induction voice broadcast module 3, suppending hole 4 and suspension line 5；It is characterized in that：The nameplate 1 is the cuboid that rigid plastics make, nameplate 1 front upper portion and lower end be respectively arranged with literal field 6 and picture region 7, the centre position of nameplate 1 is provided with infrared induction voice broadcast module 3, the centre position at four edges in the back side of nameplate 1 is provided with the strength Magnetitum 2 of circle, the upper end of nameplate 1 two, corner location is provided with suppending hole 4, suspension line 5 is provided with suppending hole 4, snak link 8 is installed additional on suspension line 5.
Further, the infrared induction voice broadcast module 3 includes the speech electronic module that speech chip U2 and its peripheral components are constituted；The peripheral components include the loudspeaker LS1 for being arranged on the infrared detection device with infrared thermal release electric process chip U1 as core of speech chip triggering end, light shutter device and being arranged in speech chip output loop；Infrared probe 11 in the front centre position of nameplate 1 is respectively arranged with photographic hole 9, vocal hole 10, and the infrared circuit；The speech chip U2 adopts read-write chip I SD1810, and in the side of nameplate 1 LED 12, S1 recording switch 13, S2 on and off switch 14 and recording jack 15 are respectively arranged with, and is accordingly equipped with the pluggable mike in recording jack 15 for recording.
Further, infrared thermal release electric process chip U1 adopts BISS0001 chips, is that, with direct current 9V cell powers, related technical parameter is：
