(1) place on the vehicle, be used for the central microprocessor of electronic traffic information,
(2) be used to read the reader of information on the storage card,
(3) be used to store the program store that after the source program compiling, becomes the CPV executable code,
(4) be used for the various memory of data of storage running,
(5) be used for the key entry device of input information,
(6) be used for the read-only intelligent memory card of storage area traffic information, it is characterized in that this vehicle electronics traffic information also comprises,
(7) the special-purpose launch pad that can in real time dynamic information in the zone outwards be launched,
(8) be distributed in the information receiver on each vehicle central microprocessor in the zone.
The job procedure of vehicle electronics traffic information system comprises that start, shutdown, YES and NO instruction carries out programming control as carrying out processing instruction, it is characterized in that adopting the following step:
(1) start, the CPU initialization,
(2) call in the program of program store,
(3) storage card of reading of accepting keyboard or touch-screen instructs,
(4) read desired zone traffic map, literal or voice messaging from storage card,
(5) starting point, the terminal point of accepting the required traffic route of sending of keyboard or touch-screen instructs, confirm,
(6) central microprocessor computing optimal path and demonstration are selected, confirm,
(7) read the up-to-date traffic information in the relevant selected path of special-purpose launch pad emission, if any obstruction, return and reselect inferior good path, as unblocked plug, screen display goes out vehicle line,
(8) continue the traffic information that reception storage card and special-purpose launch pad are launched in the process of moving, calculate the best of new route, inferior good path.
The present invention can also implement like this, and the read-only intelligent memory card is CD-ROM, IC smart card or intelligent magnetic card, and the information of storage card record is literal, image, voice, the information regular update on the storage card.Key in device and be keyboard or CRT, LCD touch-screen.Be furnished with on the central microprocessor:
(9) audiofrequency output, audio frequency amplify and loudspeaker arrangement.
The job procedure of this system can provide many selective traffic routes simultaneously.The traffic route information that provides comprises traffic route, title, distance, has a lot of social connections, traffic lights time, the item key building of specifying special way to get there, roadside and this car place particular location etc.
By above technical scheme, realized purpose of the present invention substantially.
The present invention adopts special-purpose traffic information launch pad and is distributed in the information receiver on each vehicle in the zone, can receive traffic multidate information in certain zone at any time, and this has the most real directive significance to the vehicle driver.That technical solutions according to the invention have adopted in central microprocessor is best, the comparison program of short vehicle line, promptly by suggested traffic information such as circuit length in the information launch pad storage card, special stipulation in traffic lights parking period, vehicle flowrate, flow of the people, parking site, condition of road surface and the motor road management, as certain bar road can only directly walk can not turnon left etc. regulation, compare and provide two optimal paths, selection is provided.The present invention adopts CD-ROM, IC smart card, intelligent magnetic card as storage card, and unrestricted because of storage content, its canned data can be detailed as far as possible, can be figure, literal or voice.When screen is watched in chaufeur inconvenience, can obtain instructing by voice like this, storage card be made by city or administrative region, and regular update so just can conveniently realize the clear up-to-date traffic information in the whole nation of understanding.Key entry device of the present invention is keyboard or CRT, LCP touch-screen, when can use the keyboard input instruction at one's leisure, then available touch-screen when being inconvenient to use keyboard in driving the way.
Technical solutions according to the invention are characteristics such as a kind of traffic information storage capacity is big, the reflection content is many, and information updating is convenient, and information relates to the zone extensively, can reflect real-time latest tendency road conditions, can calculate functions such as many bests, shortest path, and is easy to operate.
