Abstract

The utility model discloses an urban public transportation voice guidance system for the blind, which is provided with a single-chip microcomputer A; the input end of the single-chip microcomputer A is connected with an operation keyboard, and the output end thereof is connected with an encode control circuit, the output of which is connected with a wireless emission device; a wireless receiving device corresponding to the wireless emission device is arranged and connected with a single-chip microcomputer B through a decode control circuit; and the output of the single-chip microcomputer B is connected with a digital voice control circuit which is connected with a speaker through a voice amplifier circuit. The blind can recognize the station and the specific stop position of a taken bus according to the guiding signal emitted by the speaker, thus effectively solving the actual problem of positioning and looking for stations as well as taking a bus for the blind, and greatly facilitating the traveling of the blinds. Simultaneously, the speaker makes a sound only when the blind makes a request, thus having no influence on the normal life of residents nearby.

Description

City bus voice blind guiding system

Technical field:

The utility model relates to a kind of blind guiding system, especially a kind of simple in structure, easy to operate, can effectively guide the blind person to seek the public transport platform, correctly take the city bus voice blind guiding system of public transit vehicle.

Background technology:

With respect to other physical disabilities, eyesight physical disabilities' (blind person) trip is least easily, though some cities are provided with the sidewalk for visually impaired people in the part highway section, but can't solve the problem that the long distance trip of blind person is run into.At present, the long distance of the blind person of the overwhelming majority goes out the provisional capital and will rely on public transport, the bus of seeking bus stop and concrete circuit has just become the subject matter that the blind person ran into, even after innumerable trials and tribulations finds the station, be faced with again and do not know which bus enters the station, do not know the institute's circuit bus of taking advantage of stop particular location, so that the problem that can't take correct circuit bus.Though the bus that has was once installed the outer bus stop announcement device of car, both the driver manually started bus stop announcement device when bus enters the station, and the blind person scholar who is positioned on the platform can know whereby which bus enters the station.But because of each bus all can send the sound of calling out the stops after entering the station simultaneously, bring noise effect not only near resident, and the blind person also is difficult to differentiate the particular location of the circuit vehicle parking of taking advantage of, lost the effect of guide.The above problem makes and blind person's inconvenience of going on a journey has significantly reduced the chance that the blind person touched society, is socially reintegrated, brought into play its workmanship.

Summary of the invention:

The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, provide a kind of simple in structure, easy to operate, can effectively guide the blind person to seek the public transport platform, correctly take the city bus voice blind guiding system of public transit vehicle.

Technical solution of the present utility model is: a kind of city bus voice blind guiding system, it is characterized in that: be provided with Chip Microcomputer A, be connected to operation keyboard with the input end of Chip Microcomputer A, be connected to encoding control circuit with the output terminal of Chip Microcomputer A, the output and the wireless launcher of encoding control circuit join; Be provided with the radio receiver corresponding with wireless launcher, radio receiver joins by decoding control circuit and single-chip microcomputer B, the output of single-chip microcomputer B and numeral voice control circuit join, and the numeral voice control circuit joins by voice power amplifier and loudspeaker.

Devices such as receiving circuit of the present utility model and loudspeaker can be arranged on public transport platform or the bus, the desired signal that can send according to the blind person, quote guide signals such as public transport platform title, the concrete circuit of bus, the blind person then can be according to this guide signal, distinguish the particular location stopped of the circuit bus of taking advantage of, effectively solve the practical problems that the Blind Folks Mobile stands firm the position and seeks, takes bus, greatly facilitate blind person's trip.Have only simultaneously when the blind person sends request, loudspeaker is just sounded, and can not produce noise effect near resident normal life.

Description of drawings:

Fig. 1 is the schematic block circuit diagram of the utility model embodiment.

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: be provided with Chip Microcomputer A (AT89C2051), be connected to operation keyboard with the input end of Chip Microcomputer A, be connected to encoding control circuit (PT2262) with the output terminal of Chip Microcomputer A, the output and the wireless launcher of encoding control circuit join; Be provided with the radio receiver corresponding with wireless launcher, radio receiver joins with single-chip microcomputer B (AT89C2051) by decoding control circuit (PT2272), the output of single-chip microcomputer B and numeral voice control circuit (BLR3800) join, and the numeral voice control circuit joins by voice power amplifier and loudspeaker.

Principle of work:

Chip Microcomputer A and peripheral circuit are carried by the blind person, and single-chip microcomputer B and peripheral circuit can be installed in the public transport platform or/and on the bus.When the blind person waits for bus at platform,, can send and call out the stops or/and seek the request signal of the concrete circuit of bus by operation keyboard, Chip Microcomputer A, encoding control circuit, wireless launcher; Be arranged on the station or/and after the required radio receiver of taking on the circuit bus receives request signal, by decoding control circuit decoding and with by behind single-chip microcomputer B, numeral voice control circuit, the voice power amplifier, the voice signal that is embedded in the single-chip microcomputer B is broadcasted by loudspeaker, as " XX platform ", " the YY road is about to enter the station; eyesight physical disabilities carry out the preparation of getting on the bus; please the driver and other passengers give a hand, thanks! ".Eyesight physical disabilities this moment (blind person) have just learnt the vehicle pull-in that waits, can judge the position that vehicle is stopped by the sound that vehicle-mounted loudspeaker sent, thereby reach the purpose of correctly riding.Wireless transmit or wireless receiving distance can be set as required, and operated by rotary motion gets final product about 15 meters.When non-required take the circuit bus and enter the station after, because of coding set in signal that radio receiver received and the single-chip microcomputer B is not inconsistent, neither can trigger loudspeaker, effectively avoided the noise problem that disturbs residents.

Claims

1. city bus voice blind guiding system is characterized in that: be provided with Chip Microcomputer A, be connected to operation keyboard with the input end of Chip Microcomputer A, be connected to encoding control circuit with the output terminal of Chip Microcomputer A, the output and the wireless launcher of encoding control circuit join; Be provided with the radio receiver corresponding with wireless launcher, radio receiver joins by decoding control circuit and single-chip microcomputer B, the output of single-chip microcomputer B and numeral voice control circuit join, and the numeral voice control circuit joins by voice power amplifier and loudspeaker.
