Description
Technical field
The present invention relates to a kind of intelligent traffic administration system device, is a kind of intelligent traffic administration system device based on mobile intelligent terminal and vehicle-mounted OBD specifically.
Background technology
Intelligent transportation system is also known as intelligent transportation system, be by science and technology advanced to information techenology, computer technology, data communication technology, sensor technology, electron controls technology, automatic control theory, operational research, artificial intelligence etc. effectively integrated use in communications and transportation, Service controll and Rail car manufacture, strengthen vehicle, road, contact between user three, thus formed a kind ofly to ensure safety, raise the efficiency, the comprehensive transportation system of environmental protect, economize energy.
Head-up display Head Up Display, is called for short HUD, is also head-up display device, is the flight additional gauge generally used at present on aircraft.The meaning of looking squarely refers to that aviator does not need to bow the important information just can seeing that he needs.Head-up display appears on military aircraft the earliest, and reducing aviator needs to bow to check the frequency of instrument, avoids attention to interrupt and loses the grasp to state consciousness.Because the comfort feature of HUD and can improve flight safety, airliner also follows up installation one after another.HUD is the principle utilizing optical reflection, important flight relevent information is incident upon above a sheet glass.This what passenger cabin front end, sheet glass position, highly roughly become level with the eyes of aviator, the word of projection and image adjustment on the distance of focal length infinity, time aviator sees toward front through HUD, together with the data fusion that can easily the scene in the external world and HUD be shown.The purpose of HUD design allows aviator not need to bow the display and data of checking instrument, and remain the attitude of new line, Rapid Variable Design and eyes focal length needs of ignoring external environment between bowing and coming back constantly adjust the delay and discomfort that produce.
Partial automobile dealer also attracts client using similar device as the means of marketing, has had some automobiles dealer, have developed a kind of can compatible tire pressure tire temperature monitoring, and the multi-purpose type HUD that can be connected with automobile OBD socket, be called for short OBD+HUD+TPMS.The OBD i.e. abbreviation of " On-Board Diagnostics (OBD) ", the operation conditions from driving engine is monitored automobile by OBD system at any time, and whether tail gas exceeds standard, once exceed standard, can send warning at once.When system malfunctions, fault (MIL) lamp or check driving engine (Check Engine) warning light bright, powertrain control module (PCM) is by failure message stored in memory device simultaneously, diagnostic code can be read from PCM by certain program.According to the prompting of diagnostic code, maintainer can determine character and the position of fault quickly and accurately.System and the parts such as OBD Real-Time Monitoring driving engine, catalytic convertor, grain catcher, exhaust gas oxygensensor, emission control systems, fuel oil system, EGR.Then by the different component information relevant with discharge, ECU is connected to, when there is discharge fault, ECU record trouble information and correlative code, and given a warning by not under command light, inform chaufeur.ECU, by standard data interface, ensures the access to failure message and process.
The data of existing vehicle-mounted HUD projection has two classes, and a class connects automobile OBD interface, can show the speed of a motor vehicle, rotating speed, oil consumption, vehicle condition information etc.; Another kind of is introduce mobile navigation, can show simple and easy navigation information.
Above-mentioned various vehicle-mounted HUD function singleness, cannot realize the display of more safe early warnings and information, more cannot realize intelligent traffic administration system; In addition, due to the technical standard disunity of different automobile types, the implication that the various message code locks that vehicle OBD interface produces are expressed has each self-defining standard, these vehicle-mounted HUD can only be applicable to a kind of vehicle, whole vehicle cannot be suitable for, also cannot according to the display mode of the kind of the autonomous set and display information of the demand of user.
Summary of the invention
The present invention provides a kind of applied widely, user can the intelligent traffic administration system device based on mobile intelligent terminal and vehicle-mounted OBD of the autonomous display mode of the kind of set and display information for solving the problem, this device has vehicle condition alarm projection prompting, emergency is saved oneself and intelligent traffic administration system function, and selected applicable vehicle and the display mode of the kind of set and display information by software.
The technical scheme that the present invention adopts for technical solution problem is as follows:
Intelligent traffic administration system device based on mobile intelligent terminal and vehicle-mounted OBD of the present invention comprise for vehicle front windshield projected image projector, be connected to the HUD terminal of projector input end, described HUD terminal connects the OBD interface of vehicle by data line, this HUD terminal has the locating module that can produce position coordinate, described HUD terminal connects mobile intelligent terminal by bluetooth, and described mobile intelligent terminal has:
