Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
In order to improve share-car efficient, save storage space, the embodiment of the invention provides a kind of taxi system, referring to Fig. 1, Fig. 2 and Fig. 3, sees hereinafter for details and describes:
A kind of taxi system; Comprise: embedded system 12; Embedded system 12 links to each other with audio-frequency module 1, video module 2, roof display 4, print module 6, keyboard 10, power supply 11, voice module 13 and clock circuit 14 respectively; Power supply 11 provides power supply for embedded system 12, and audio-frequency module 1 obtains recording with video module 2, the data of recording a video; Print module 6 is printed passenger's cost information; The taxi system also comprises:
Button 9 is used to trigger embedded system 12 control voice modules 13 and plays voice signal fast; Trigger that audio-frequency module 1 obtains recording with video module 2, the data of recording a video, and will record, the data of recording a video and time data store in the nonvolatile memory 15;
Nonvolatile memory 15 is used for storage recording, video recording data and time data;
Roof display 4 is used to show the destination of the passenger from keyboard 10 inputs;
Hall switch circuit 8 or GPS module 7 are used to import and the accumulative total mileage number that the passenger took;
The valuation of 4 kinds of distance expenses is closed and is taken advantage of display 3, is used for respectively 4 kinds of distance expenses being shown.
Wherein, the later stage is transferred recording and video recording data at any time for ease, and this taxi system also comprises: communication interface 5, communication interface 5 are used for transmission recording and video recording data.
Through on roof display 4, showing passenger's destination, improved the efficient of share-car.
Wherein, in order to satisfy the multiple needs in the practical application, embedded system 12 is specially: ARM, DSP, FPGA or MCU.
The embodiment of the invention is that S3C2440 is that example describes with the model of ARM, and when specifically realizing, the embodiment of the invention does not limit this.
Wherein, fast button 9 is used for behind first passenger, second passenger, the 3rd passenger and the 4th passenger loading, triggering embedded system 12 control voice modules 13 and playing voice signals; Trigger that audio-frequency module 1 obtains recording with video module 2, the data of recording a video, and will record, the data of recording a video and time data store in the nonvolatile memory 15.
Wherein, fast button 9 can for: empty wagons pilot lamp and button etc., when specifically realizing, the embodiment of the invention does not limit this.
Wherein, nonvolatile memory can for: FLASH storer, flash disk or hard disk etc., when specifically realizing, the embodiment of the invention does not limit this.
The working method of a kind of taxi system that explains that the embodiment of the invention provides with concrete instance below, see hereinafter for details and describe:
When first (criticizing) passenger loading, the driver presses quick button 9, and 13 broadcasts of button 9 triggering embedded systems 12 control voice modules " take by welcome fast! Where may I ask you? " Play again after the several seconds at the interval " for environmental protection, alleviate traffic congestion and convenient more passenger; you allow share-car? " Finish; Triggering through quick button 9 starts audio-frequency module 1 recording and video module about about 20 seconds time of 2 video recordings immediately, and embedded system 12 is saved in recording, video recording data and time this moment in the nonvolatile memory 15.Allow the back driver to show in the share-car that obtains the passenger through keyboard 10 input passengers' destination (direction) and at roof display 4; Embedded system 12 starts first passenger's fare accumulative total simultaneously; Promptly write down the time at once from clock circuit 14; Through Hall switch circuit 8 inputs and accumulative total this position (criticizing) mileage number that the passenger took, or through 7 inputs of GPS module and accumulative total this position (criticizing) mileage number that the passenger took.When second (criticizing) passenger loading; The driver presses quick button 9; Embedded system 12 starts second (criticizing) passenger's fare accumulative total; Promptly write down the time at once from clock circuit 14, through Hall switch circuit 8 inputs and accumulative total this position (criticizing) mileage number that the passenger took, or through 7 inputs of GPS module and accumulative total this position (criticizing) mileage number that the passenger took.Equally; When if the 3rd (criticizing), the 4th passenger loading are arranged; The driver presses quick button 9, and button 9 triggers second (criticizing) passenger's of embedded system 12 corresponding startups fare accumulative total fast, promptly writes down the time at once from clock circuit 14; Through Hall switch circuit 8 inputs and accumulative total this position (criticizing) mileage number that the passenger took, or through 7 inputs of GPS module and accumulative total this position (criticizing) mileage number that the passenger took; The valuation of 4 kinds of distance expenses is closed and is taken advantage of display 3 to show the expense of each time respectively.
In sum; The embodiment of the invention provides a kind of taxi system, and button triggers embedded system control voice module and plays voice signal fast, and audio-frequency module and video module obtain recording and the data of recording a video; And be kept in the nonvolatile memory, saved storage space; And, improved the efficient of share-car through roof display demonstration passenger's destination; Valuation display through 4 kinds of distance expenses shows 4 kinds of distance expenses; Through Hall switch circuit or GPS module, input and the accumulative total mileage number that the passenger took have improved precision and efficient; Make driver's operation easy through this system, not only can improve taxi efficiency of operation and income, make more passenger served, reduce the effect of urban traffic blocking and vehicle operating carbon emission timely; Also can make things convenient for driver's operation, avoid the dispute that brings because of share-car.
