Description
Technical field
The present invention relates to Traffic Systems field, particularly a kind of public bus voice reporting station system.
Background technology
Along with socioeconomic development and environmental pollution more and more serious, bus has become the vital part of urban transportation, is the preferred traffic mode of most of travelers.Due to urban transportation build growing, the former method of manually calling out the stops can not meet present demand, calls out the stops and points out at a lot of local voice automatic broadcastings of all having carried out self-service ticketing.
At present, public bus voice reporting station system mainly contains three kinds: a kind of is the position that the information that receives by GPS is calculated this car, when Vehicle Driving Cycle is to apart within the scope of website certain distance time, do not need artificial any operation, system is carried out sound broadcast automatically, but the cost of equipment is high and definite difficulty of position to vehicle is large; Another kind is to use radio RF recognition technology, at each platform, a radio-frequency (RF) transmitter is installed, constantly transmit, in bus drives to apart from platform certain limit and while receiving corresponding radiofrequency signal, bus will carry out voice automatic broadcasting, and this system is had relatively high expectations and drops into larger platform construction; Having a kind of is that the corner pulse of bus axletree is measured again, and measured value and setting value are made comparisons to determine the time of calling out the stops, and this requires the circuit of Vehicle Driving Cycle strictly to fix, and just can not accurately call out the stops otherwise call out the stops.
Summary of the invention
In view of this, the object of this invention is to provide a kind of public bus voice reporting station system, cost is reasonable, simple in structure and can accurately call out the stops.
The object of the invention is to be achieved through the following technical solutions:.
This public bus voice reporting station system, comprises single-chip microcomputer, speech chip, key-press module, display, microphone for recorded speech, high frequency power amplifier, for playing loudspeaker, reset circuit, crystal oscillator and the power supply of voice; The input end of described single-chip microcomputer is connected with reset circuit, crystal oscillator, power supply and key-press module respectively, the output terminal of single-chip microcomputer is connected with speech chip and display respectively, the input end of described speech chip is also connected with microphone, and the output terminal of described speech chip is connected with high frequency power amplifier, loudspeaker successively.
Further, described power acquisition is system power supply with USB power lead.
The invention has the beneficial effects as follows:
This public bus voice reporting station system, cost is reasonable, simple in structure and can accurately call out the stops.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating below, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized and be obtained by instructions and claims below.
Brief description of the drawings
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, wherein:
Fig. 1 is module connection diagram of the present invention.
Embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.Should be appreciated that preferred embodiment is only for the present invention is described, instead of in order to limit the scope of the invention.
Public bus voice reporting station system of the present invention, comprises single-chip microcomputer, speech chip, key-press module, display, microphone for recorded speech, high frequency power amplifier, for playing loudspeaker, reset circuit, crystal oscillator and the power supply of voice; The input end of single-chip microcomputer is connected with reset circuit, crystal oscillator, power supply and key-press module respectively, the output terminal of single-chip microcomputer is connected with speech chip and display respectively, the input end of speech chip is also connected with microphone, and the output terminal of speech chip is connected with high frequency power amplifier, loudspeaker successively.In the present embodiment, system single-chip microcomputer is 51 serial 89C52 single-chip microcomputers, as master control system chip controls speech chip and LCDs; Speech chip is ISD4004, and external microphone becomes voice recording and playing circuit with set of speakers, and wherein, loudspeaker is driven by audio-frequency power amplifier LM386; Adopt LCD12232 to carry out display text information as display, certainly can select the device of other model.The realization of each function adopts the mode of button to realize, major function has the broadcasting of reporting travel direction and arrival station and next stop name of station and signal language, LCDs shows arrival station and next stop name of station, and this system can also be removed and record playing voice.
Further improve, power acquisition is system power supply with USB power lead.
By microphone, system is recorded, the voice transfer of typing is to speech chip, then by speech chip, the voice of typing carried out to data processing; And store and set up corresponding sound bank.In the time that system is reported the voice of typing, speech chip reads and synthetic speech signal the voice messaging of typing, then carries out sound broadcast and prompting etc. by the loudspeaker in voice output circuit.Meanwhile, single-chip microcomputer utilizes program code Word message to be read and sent into LCD display to carry out the demonstration to arrival station name of station and next stop name of station.In the time that bus drives to certain platform, bus driver carrys out control system by the mode of button and carries out the automatic broadcasting of voice.In addition, this system is also determined the order of the voice of calling out the stops and the order of demonstration name of station according to the travel direction of bus.
This public bus voice reporting station system, cost is reasonable, simple in structure and can accurately call out the stops.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of claim scope of the present invention.
