Abstract
An electronic omniselector that is used to lead the blind people to pass the crossroads comprises a signal emitter and a transmitting coil that are positioned at the crossroads and a signal receiver carried by the blind people. According to the situation that whether the green traffic light is on or not, the signal emitter controls a voice chip that stores the voice prompt that whether the blind people can pass the crossroads or not, and transmits the speech signal through the transmitting coil so that the blind people can react according to the voice prompt received by the signal receiver.
Description
Technical field
The utility model relates to a kind of blind traffic telltale, is applicable to that especially the guiding blind person passes through the auditory tone cues device of intersection.
Technical background
In the face of present complicated traffic route, the situation as the blind person of disadvantaged group often is difficult to distinguish the road surface particularly is difficult to pass through at the crossing that many roads intersect especially.At present extremely few relevant for the jaywalk device of crossing of guiding blind person, as the patent No. is that 01229320 blind person crosses the street reminiscences, when the East and West direction green traffic lamp was bright, loudspeaker sent a kind of loud euphony, and the blind person that prompting waits at the East and West direction crossing crosses the street; When the north-south green traffic lamp was bright, loudspeaker sent another kind of loud euphony, and the blind person that prompting waits at the crossing, north-south crosses the street.This type of blind person crosses the street reminiscences and only is applicable to the crossroad, versatility is not strong, the blind person can't distinguish the four corners of the world naturally, then can't tackle when facing other such as complex situations such as T-shaped road junction, big word crossing, rice word crossings, and this type of reminiscences to provide the sound effect of prompting not obvious, flooded by the road noise easily.
Technology contents
The purpose of this utility model is to allow the blind person face complicated day by day traffic conditions still can pass through the intersection by the voice suggestion of omniselector easily.
The technical solution of the utility model is as follows:
Blind person intersection electronic navigation device comprises shell, circuit board, loudspeaker, be characterized in: this omniselector comprises signal projector that is placed on the intersection and the signal receiver of being taken with oneself by the blind person, circuit board comprises signal transmission circuit and signal receiving circuit, signal transmission circuit is fixed on the signal projector, two input ends of signal projector are connected in parallel on the two ends of crossing green traffic lamp, output terminal is connected with the transmitting coil L1 that is placed on the intersection, transmitting coil can be embedded in the below, sidewalk for visually impaired people, perhaps hang over the top, sidewalk for visually impaired people, also can be placed on the side; Signal receiving circuit is fixed on the signal receiver, and is connected with loudspeaker.
Above-described blind person intersection electronic navigation device, the VCC pin of the speech chip Audiol of signal transmission circuit connects+the 5V direct current, the Outl pin is succeeded the Chang Kaiduan of electrical equipment K1, the VCC pin of Audio2 connects+the 5V direct current, the Outl pin connects the normal-closed end of K1, be connected to rectifier bridge D1 behind the input end electric wire process transformer T1 in parallel with green traffic light, rectifier bridge D1 is connected to the control end of relay K 1, the output terminal process resistance R 1 of relay K 1 is connected to the input port of power amplifier AR1, and the output terminal of power amplifier AR1 is connected to transmitting coil L1; The input end that is connected amplifier AR2 after coil L2 in the signal receiving circuit and capacitor C 1 parallel connection again, the output terminal of AR2 connects loudspeaker.
Above-described blind person intersection electronic navigation device, the voice suggestion of speech chip Audio1 storage P Passable, the Audio2 storage voice suggestion that no through traffic.
Substantive distinguishing features of the present utility model and progress are:
Place signal projector and transmitting coil according to the situation of intersection, the voice suggestion that the signal receiver of blind person from hand sends judges and whether pass through, thus a difficult problem of passing through when having solved the blind person in the face of the intersection of complexity.
The utility model stable performance, simple to operate, with low cost, power consumption is little, and generalization is strong.
Description of drawings
Fig. 1 is the utility model blind person intersection electronic navigation device structural representation;
Fig. 2 is the signal transmission circuit figure of signal projector of the present utility model;
Fig. 3 is the signal receiving circuit figure of signal receiver of the present utility model;
Fig. 4 is that transmitting coil of the present utility model is placed the orientation synoptic diagram.
Embodiment
As shown in Figure 1, two input ends that are placed on the signal projector 1 of intersection are connected in parallel on the two ends of crossing green traffic lamp, output terminal is connected with the transmitting coil 3 that is placed on the intersection, signal projector 1 is bright according to green light denys the voice prompt of selecting speech chip, by transmitting coil 3 signal is sent, the signal receiver 2 of blind person's body band sends the corresponding prompt sound according to the signal that receives and guides the blind person to pass through the road intersection.
As shown in Figure 2, green traffic lamp can be automatic or manual control, and when green light did not work, the normal-closed end of relay 7 was connected on the prompting speech chip 6 that no through traffic, and voice signal is launched by power amplifier 11 and transmitting coil 3; When green light brightened, transformer 8 was started working, and obtains the control voltage of relay 7 and relay switch K1 film dancing is connected on the speech chip 5 of prompting P Passable by rectifier bridge 9, and voice signal is launched by power amplifier 11 and transmitting coil 3 equally.
As shown in Figure 3, the coil 12 of signal receiver 2 promotes loudspeaker 15 work through power amplifier AR2 after receiving sound signal, thereby sends relevant prompt tone.
As shown in Figure 4, the position of transmitting coil 3 is set according to the difference of road intersection situation, if crossroad or Y junction are then placed coil as shown in the figure, because adjacent coil signal direction is opposite, be easy to generate interference, can receive accurately clearly that the voice suggestion signal is the scope that standard is suitably adjusted emission so must enter transmitting boundary with signal receiver 2.
