Description
Technical field
The present invention relates to a kind of vehicle-mounted head-up display device, is a kind of vehicle mounted multimedia HUD device based on mobile intelligent terminal specifically.
Background technology
Head-up display Head Up Display, is called for short HUD, is also head-up display device, is the flight supplementary instrument generally used at present on aircraft.The meaning of looking squarely refers to that pilot 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 pilot needs to bow to check the frequency of instrument, avoids notice to interrupt and loses the grasp to state consciousness.Because the convenience 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 pilot, the word of projection and image adjustment on the distance of focal length infinity, time pilot 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 pilot 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 " OBD ", the operation conditions from 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 engine (Check Engine) emergency warning lamp bright, powertrain control module (PCM) is by failure message stored in storer simultaneously, diagnostic trouble code can be read from PCM by certain program.According to the prompting of diagnostic trouble code, maintenance personal can determine character and the position of fault quickly and accurately.System and the parts such as OBD Real-Time Monitoring engine, catalytic converter, grain catcher, lambda sensor, emission control systems, fuel 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 trouble light, inform driver.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 vehicle mounted multimedia HUD device based on mobile intelligent terminal 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:
Vehicle mounted multimedia HUD device based on mobile intelligent terminal 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, described HUD terminal connects mobile intelligent terminal by bluetooth, and described mobile intelligent terminal has:
Bluetooth communication module, for connecting HUD terminal and bi-directional transfer of data;
Local data base, for storing various information, the technical parameter of each vehicle and the multi-medium data of projection information;
Application software travelling mechanism, is sent to HUD terminal by bluetooth by the information after process subsequently for searching with the information in called data storehouse and being processed.
Described mobile intelligent terminal also has wireless network communication module, for connecting cloud computing server and bi-directional transfer of data; Described cloud computing server has:
Cloud database, the real time information data run for store car and represent the multi-medium data of travel condition of vehicle;
Cloud computing travelling mechanism, for calculating and process the real-time information of the vehicle operating from mobile intelligent terminal.
After adopting technique scheme, the data processing that this vehicle mounted multimedia HUD device utilizes mobile intelligent terminal equipment powerful and storage capacity, vehicle condition alarm projection prompting can not only be provided, vehicle prompt facility is saved oneself and driven in the wrong direction to emergency, and select applicable vehicle and the display mode of the kind of set and display information by software.Applied widely, easy to use, Consumer's Experience is good.By the bidirectional data transfers of cloud computing server, not only can obtain real-time road condition information in time, vehicle operation data can also be transferred to cloud computing server, for can only traffic administration provide convenience.
Accompanying drawing explanation
Fig. 1 is the functional block diagram of one embodiment of the invention.
Fig. 2 is the flow chart of data processing figure of one embodiment of the invention.
Embodiment
As shown in Figure 1, vehicle mounted multimedia HUD device based on mobile intelligent terminal of the present invention comprise for vehicle front windshield projected image projector 1, be connected to the HUD terminal 2 of projector 1 input end, described HUD terminal 2 connects the OBD interface 5 of vehicle, for reading the real time data of vehicle operating and uploading to HUD terminal 2 by data line.Described HUD terminal 2 connects mobile intelligent terminal 3 by bluetooth, and described mobile intelligent terminal 3 has:
