Abstract

Provided is a taxi passenger article anti-loss prompting apparatus, comprising three parallel magnetron trigger switches, a time-delay type trigger control circuit and a warning prompt circuit. The taxi passenger article anti-loss prompting apparatus is installed on a taxi; when a passenger is getting off and opens a car door, voice signals of ''please take your belongings'' are emitted to prompt the passenger to take articles and to effectively avoid property loss of the passenger.

Description

The anti-alarm set of losing of taxi passenger device

Technical field

The utility model relates to a kind of electronic circuit, a kind of anti-alarm set of losing of taxi passenger device that is used for.

Background technology

The soil that the passenger takes, the situation of lost objects happens occasionally when getting off, and article cause greater loss for passenger's property in case loss just is difficult to give for change.Therefore, design the anti-alarm set of losing of a kind of taxi passenger device, guaranteeing that passenger's property is not suffered a loss promptly becomes the purpose of the utility model.Do not see as yet at present the anti-report of losing alarm set of similar taxi passenger device is arranged.

Summary of the invention

The utility model is intended to propose a kind of anti-alarm set of losing of taxi passenger device that can guarantee that passenger's property is not suffered a loss.The anti-loss of this taxi passenger device alarm set comprises magnetic control trigger switch, delayed type trigger control circuit and the caveat cue circuit of 3 parallel connections.One end of the magnetic control trigger switch of 3 parallel connections links to each other with 2 pin of resistance R 1 and IC1555 simultaneously, and an other end of the magnetic control trigger switch of 3 parallel connections links to each other with negative pole, capacitor C 1, C2, C3, the negative pole of C4,1 pin of IC1555 and 7 pin of IC25603 of 6V direct supply, the emitter of triode VT simultaneously.7 pin of IC1555 link to each other with 6 pin of IC1555, the positive pole of capacitor C 1 and the end of variable resistor RP simultaneously.The positive pole of 6V direct supply links to each other with 8 pin of resistance R 1, RP, R2, R3 and IC1555 through switch S A1, and 5 pin of IC1555 link to each other with the positive pole of capacitor C 2.3 pin of IC1555 link to each other with the positive pole of

capacitor C

4 and 2 pin of IC25603 simultaneously.3 pin of IC25603 link to each other with 8 pin of IC1555 through

resistance R

3, and 10 pin of IC25603 link to each other through capacitor C 5 with 11 pin, and 8 pin of IC25603 link to each other through capacitor C 6 with 9 pin, and 1 pin of IC25603 links to each other through resistance R 4 with 4 pin.The output terminal of IC25603 links to each other with the base stage of triode VT, and triode VT collector links to each other with 3 pin of IC25603 through horn coil.

The anti-alarm set of losing of this scholar's passenger device, 3 magnetic control trigger switch GH1～GH3 are installed on respectively except driver's front truck on one side and a left side, back, the right car door in back, and no matter the passenger from which student's car can both trigger reminiscences.The magnetic control trigger switch adopt magnet near the time break off, magnet away from the time closed magnetic control reed switch relay.

The anti-alarm set of losing of this scholar's passenger device, IC1555 circuit and RP, C1 form the monostable time delay circuit, by 2 pin input trigger pip.At ordinary times, under the attraction of magnet, inner contact is in off-state by the reed switch relay of permanent magnet control, and power supply makes 2 pin of IC1555 be in high level through R1, and monostable circuit is in stable state, its 3 pin output low levels.When the passenger gets off when opening car door, permanent magnet separates with tongue tube, and the tongue tube inner contact is closed; Make the 2 pin ground connection of IC1555 become low level, monostable circuit is triggered and overturns, 3 pin output high level; Go after the output to trigger the caveat cue circuit, send signal language.The delay time of monostable time delay circuit is regulated RP and is made the caveat cue circuit can at least intactly finish the signal language of " woulding you please with goodies " by RP and C1 decision.

The anti-alarm set of losing of this scholar's passenger device, IC2 is the caveat cue circuit, model is 5603, after it is triggered, will send one " woulding you please be with goodies ", and constantly repeats, till the delay circuit time-delay finishes output low level.

The beneficial effect of the utility model is: can prevent to cause when the passenger from taking taxi the loss of property loss, protection passenger property is had positive meaning.

Accompanying drawing is the structure principle chart of the anti-alarm set of losing of this taxi passenger device.

Embodiment

As shown in the figure, the anti-loss of this taxi passenger device alarm set comprises magnetic control trigger switch, delayed type trigger control circuit and the caveat cue circuit of 3 parallel connections.

As shown in the figure, the anti-alarm set of losing of this scholar's passenger device, 3 magnetic control trigger switch GH1～GH3 are installed on respectively except driver's front truck on one side and a left side, back, the right car door in back, and no matter the passenger from which student's car can both trigger reminiscences.The magnetic control trigger switch adopt magnet near the time break off, magnet away from the time closed magnetic control reed switch relay.

As shown in the figure, the anti-alarm set of losing of this scholar's passenger device, IC1555 circuit and RP, C1 form the monostable time delay circuit, by 2 pin input trigger pip.At ordinary times, under the attraction of magnet, inner contact is in off-state by the reed switch relay of permanent magnet control, and power supply makes 2 pin of IC1555 be in high level through R1, and monostable circuit is in stable state, its 3 pin output low levels.When the passenger gets off when opening car door, permanent magnet separates with tongue tube, and the tongue tube inner contact is closed; Make the 2 pin ground connection of IC1555 become low level, monostable circuit is triggered and overturns, 3 pin output high level; Go after the output to trigger the caveat cue circuit, send signal language.The delay time of monostable time delay circuit is regulated RP and is made the caveat cue circuit can at least intactly finish the signal language of " woulding you please with goodies " by RP and C1 decision.

As shown in the figure, the anti-alarm set of losing of this scholar's passenger device, IC2 is the caveat cue circuit, model is 5603, after it is triggered, will send one " woulding you please be with goodies ", and constantly repeats, till the delay circuit time-delay finishes output low level.
