The sign-plate for language prompting comprises a rectangular box and a language circuit. The language circuit mainly comprises a pulse carrier-frequency circuit, a multivibrator, a frequency selecting and receiving circuit, a delaying electronic switching circuit and a speech circuit. An infrared luminous tube D3, which is a sensing element, and an infrared receiving tube D1 are respectively connected with the output end of the pulse carrier-frequency circuit and the input end of the frequency selecting and receiving circuit. D1 and D2 are arranged at the place of the small hole of the same panel of box body panels, when a person or an object approaches, the utility model can sent out a language prompt whose content is consistent with the sign-plate, thus electric shock can be avoided. The utility model, which has the advantages of beautiful appearance, reasonable structure and low cost, is suitable for hot-line work, and can be used for high-pressure apparatus.

Description

Sign-plate for language prompting

The utility model belongs to the prohibitory sign technical field.

Usually, to electric power apparatus examination the time or for not allowing approaching high-tension apparatus, generally all adopt the mode that hangs up sign board to come reminds people to note, but at present only apparent word on the sign board that uses is mute, therefore has only after people walk close to see clearly word on the sign board, just know and note or avoid, and people few for character learning or that have defective vision uses this simple sign board that shows word, still has the possibility of meeting accident.

The purpose of this utility model is to be installed in the box body after existing language circuit is mixed specific language integrated package, as people or thing near the time, can send with sign board the consistent a kind of verbal cue sign board of apparent content.

The utility model is made of box body and language circuit.Box body is a rectangular box, and the material of box body is plastics.The language circuit is located in this box.The language circuit is made of pulse carrier-frequency circuit (Ic5, D2, C9, R4, R5), current-limiting resistance R6, infraluminescence pipe D3, multivibrator (Ic6, D4, C11, C12, R7, R8), frequency-selecting receiving circuit (Ic1, D1, L1, C1, C2, C3, C4, R1), delay electronic switch circuit (Ic2, R2, C5), sound circuit (Ic3, Ic4, C6, C7, C8, C9, R4, Y), direct supply, power switch.Current-limiting resistance R6 and infraluminescence pipe D3 series connection are at the output terminal (3 pin of Ic5) of pulse carrier-frequency circuit, and the anode of infraluminescence pipe D3 connects negative supply; The output of multivibrator (3 pin of Ic6) is connected to the zero setting end (4 pin of Ic5) of Ic5 in the pulse carrier-frequency circuit; Pulse carrier-frequency circuit, current-limiting resistance R6, infraluminescence pipe D3, multivibrator constitute the infrared emission oscillatory circuit.In the frequency-selecting receiving circuit, the negative electrode of infrared receiving tube D1 connects positive supply, anode connects input end 7 pin of Ic1, the output terminal of frequency-selecting receiving circuit (1 pin of Ic1) connects the input end (2 pin of Ic2) of delay electronic switch circuit, and the output terminal of delay electronic switch circuit (3 pin of Ic2) meets the filter capacitor C9 of sound circuit; 1 pin of language integrated package Ic3,3 pin all connect negative supply in the sound circuit, 5 pin connect the output terminal (3 pin of Ic2) of delay electronic switch circuit, 2 pin, 4 pin of power discharging integrated block Ic4 all connect negative supply, 6 pin connect the output terminal (3 pin of Ic2) of delay electronic switch circuit, 5 pin meet loudspeaker Y through coupling capacitance C8, are connected to negative supply again.Infraluminescence pipe D3 and infrared receiving tube D1 are located on the same plane of box body panel in the language circuit.The language that the language integrated package sends is for " to halt! Keep Clear-High Voltage ", " No climbing, Keep Clear-High Voltage ", " No switching on, the someone works ", " No switching on, circuit have the people to keep in repair ".

The utility model good looking appearance, reasonable in internal structure, reaction is responsive, and cost is low, is applicable to hot line job or high-tension apparatus place.

Accompanying drawing 1 is the utility model language circuit theory diagrams.

Accompanying drawing 2 is the utility model course of work block schemes.

Accompanying drawing 3 is the utility model box body synoptic diagram.

Accompanying drawing 4 is the utility model embodiment accompanying drawings.

Now by reference to the accompanying drawings the utility model is described further.

To be installed in the box shown in the accompanying drawing 3 by the language circuit that accompanying drawing 1 connects. The pulse carrier-frequency circuit produces different frequencies of oscillation from multivibrator, R6 is the current-limiting resistance of infraluminescence pipe D3, changes the resistance of R6, can control the transmitting power of D3, be the sensitivity distance of control circuit, infraluminescence pipe D3 and infrared receiving tube D1 are located on the same plane of box body panel. At ordinary times, unmanned or barrier near the time, infrared receiving tube D1 does not receive the optical signal that infraluminescence pipe D3 launches, namely frequency selection circuit does not receive the signal of same frequency and no-output, delay electronic switch circuit, sound circuit all are in off position. As people or barrier near sign board during to certain distance, refraction was returned after the optical signal of infraluminescence pipe D3 emission was met people or thing, D1 receives by infrared receiving tube, at this moment, optical signals L1, the C1 of the same frequency that D1 is received carry out frequency-selecting, output after Ic1 amplifies, its output signal Time delay electronic switching circuit conducting, sound circuit gets electric, and Ic3, Ic4 start working, and loudspeaker sends the language consistent with the sign board content. Continue for some time and automatically close afterwards, this delay time is determined by R2 and C5. Until when having people or thing to reaccees sign board, the language circuit repeats the above-mentioned course of work again, the course of work is referring to accompanying drawing 2.

Embodiment:

Press rectangular box of accompanying drawing 3 designs, show " No switching on, someone work " printed words on the surface of box, between word, make a call to two apertures, sound circuit as shown in Figure 1 is installed in the box,, the infraluminescence pipe D3 in the circuit in the language and infrared receiving tube D1 is fixed on two aperture places of box body panel referring to accompanying drawing 4, the language integrated package of " No switching on; the someone works " is inserted in the sound circuit again, constitute a complete verbal cue sign board, note is made " A "." A " is placed on the brake lever place, opens the DC power supply switch in " A ", during near " A ", " A " will send the verbal cue of " No switching on, the someone works " as people or thing.
