Summary of the invention
Technical matters to be solved by this invention is: propose a kind of navigation safety system for preventing fatigue driving, to driver, whether judgement is analyzed in fatigue driving, reminds driver.
The present invention solves the problems of the technologies described above adopted technical scheme:
A navigation safety system for preventing fatigue driving, comprising: vehicle mounted guidance terminal and bearing circle data trap;
Described bearing circle data trap is used for gathering bearing circle service data and sends vehicle mounted guidance terminal to;
On described vehicle mounted guidance terminal, be loaded with intelligent navigation application module and fatigue driving analysis module; Described intelligent navigation application module is used for providing the real-time navigation of road information, and sends road information to fatigue driving analysis module; Described fatigue driving analysis module carries out the judgement of fatigue driving analysis and carries out corresponding operating according to judged result in conjunction with current road information and bearing circle service data.
Further, described bearing circle service data comprises: left-hand rotation data, right-hand rotation data, craspedodrome data, automobile gears data, front and back lamp data.
Further, described intelligent navigation application module also carries out sectional drawing to the navigation of current road conditions during as fatigue driving state and sends fatigue driving analysis module to, the analysis for the later stage to fatigue driving reason for judging that at fatigue driving analysis module chaufeur is current.
Further, the judgement that described fatigue driving analysis module carries out fatigue driving analysis in conjunction with current road information and bearing circle service data comprises: fatigue driving analysis module by chaufeur the bearing circle operation information of current road and chaufeur operating habit data message contrast, when all there is deviation within a certain period of time, judge to be now fatigue driving state.
Further, the operating habit data message of described chaufeur derives from the collection to chaufeur normal operative orientation dish data in advance, concrete mode is: the road of selecting to have different traffic informations by intelligent navigation application module, confirming that chaufeur does not guide driving fatigue driving in the situation that, bearing circle data trap Real-time Collection bearing circle data send vehicle mounted guidance terminal to and store, the operating habit data message using the service data of storage as chaufeur.
Further, described fatigue driving analysis module carries out corresponding operating according to judged result and comprises: if chaufeur is current carries out warning reminding for fatigue driving state in judgement.
The invention has the beneficial effects as follows: whether judgement is analyzed in fatigue driving to driver, remind driver, effectively reduce the traffic accident causing because of fatigue driving.
Accompanying drawing explanation
Fig. 1 is the mutual schematic diagram of the navigation safety system in the present invention.
The specific embodiment
The present invention is intended to propose a kind of navigation safety system for preventing fatigue driving, and to driver, whether judgement is analyzed in fatigue driving, reminds driver.Its core concept is: the bearing circle operating habit while gathering chaufeur normal driving, in driver's driving procedure, in real time the service data of bearing circle is gathered, the traffic information that combined with intelligent navigationsystem is obtained, by the service data of bearing circle and driver's operating habit is contrasted and determines whether fatigue driving, plays reminding effect to driver.
Below in conjunction with accompanying drawing, the solution of the present invention is done further to describe:
As shown in Figure 1, the navigation safety system of the preventing fatigue driving in the present invention comprises vehicle mounted guidance terminal and bearing circle data trap;
Wherein, bearing circle data trap is used for gathering bearing circle service data and sends vehicle mounted guidance terminal to; Related content for bearing circle service data comprises: left-hand rotation data, right-hand rotation data, craspedodrome data, automobile gears data, front and back lamp data.On concrete enforcement, data trap is by CAN bus, directly above-mentioned related data content uploading in the CPU of vehicle mounted guidance terminal, wait pending data relatively and analyze.
In vehicle mounted guidance terminal, be loaded with intelligent navigation application module and fatigue driving analysis module; Described intelligent navigation application module is used for providing the real-time navigation of road information, and sends road information to fatigue driving analysis module; Described fatigue driving analysis module carries out the judgement of fatigue driving analysis and carries out corresponding operating according to judged result in conjunction with current road information and bearing circle service data.
In the specific implementation, operating habit information to bearing circle while first needing to gather user's normal driving, using and as the later stage, judge whether the basic data of fatigue driving, the mode gathering is as follows: driver selects the some sections of roads that traffic information is abundant by the intelligent navigation application module in vehicle mounted guidance terminal, carry out chaufeur and guide driving, in the situation that confirming that chaufeur is not tired, chaufeur is driven according to information indicating, by bearing circle data trap, the data of driver's operation bearing circle are gathered to storage, the operating habit information of usining as chaufeur, road conditions are selected mainly to comprise: cross roads, T-shaped road junction, one-way road, double star road, Multiple Intersections, expressway road, bridge way, overpass road, the roads such as underway and tunnel.Because the traffic information of different roads is all different, in order to improve the accuracy of later stage to fatigue driving analysis, can repeatedly in the road conditions of these selections, to the data of direction of operating dish, gather storage.
To those skilled in the art, be understandable that, early stage is more for the data acquisition of driver's operating habit, and it is just more accurate that contrast is analyzed in the fatigue driving in later stage;
After the data of having stored a certain amount of driver's operating habit, just can enable fatigue driving analytic function, it specifically comprises:
Driver, drive in driving procedure, the data of bearing circle data trap Real-time Collection driver direction of operating dish, and send data to vehicle mounted guidance terminal, in conjunction with current road conditions information, by the data of driver's direction of operating dish of current collection and driver, the normal running custom on corresponding road conditions contrasts vehicle mounted guidance terminal, when finding to have deviation within a certain period of time always, can be judged to be chaufeur current is fatigue driving state, now can send alarm to chaufeur, can also carry out sectional drawing to the navigation of current road conditions and be convenient to chaufeur fatigue analysis driving reason.
