The system that below sets forth the alarming and reminding vehicle hypervelocity guider realizes principle.
Described guider 100 receives wireless signals by position signalling receiving element 20, as gps signal and/the GPSOne signal, guider 100 can clearly be known positional information (as latitude and longitude coordinates) and the velocity information of oneself of oneself;
Whether the control module 10 of guider 100 judges self speed greater than residing road standard of the limited speed, if greater than standard of the limited speed, then surpasses standard of the limited speed by voice or picture cues present speed.
When the speed of guider 100 during near the standard of the limited speed of road, the instantaneous velocity of guider 100 may surpass the standard of the limited speed of road, if mechanically with this instantaneous velocity as basis for estimation, then may cause frequent hypervelocity alarm or wrong report.Therefore, can adopt the mode of average velocity to surpass the standard of road speed limit as the judgement speed of a motor vehicle, thereby reduce rate of false alarm as the average velocity in 1 second, 10 seconds.
No matter with the gps signal receiver still with the GPSOne signal receiver during as signal receiving device, the capital is because the reasons such as base station distribution situation of meteorology, geographical environment, shielding or mobile cellular network make receiving trap can't obtain positional information and velocity information within a certain period of time.Therefore in the period, can't judge whether the speed of guider 100 surpasses standard of the limited speed at this section.In fact, when dropout took place, the current location of guider 100 was extrapolated in the position when speed that can be by guider 100 and dropout.As previously mentioned, if in guider 100, increase by a velocity pick-up unit 90, this sensing unit 90 comprises a speed pickup, when gps signal or GPSOne dropout, speed pickup sends acquisition speed to control module 10, therefore still can know the speed of guider 100 accurately, thereby overcome the problem that when dropout, can't obtain the speed of a motor vehicle.Certainly, under less demanding situation to velocity accuracy, also can omit this velocity pick-up unit 90, with the travelling speed of dropout moment as basis for estimation, and draw approximate vehicle instantaneous velocity and positional information, can't obtain the defective of the speed of a motor vehicle when remedying dropout.
For the user of this type of guider, wish that especially the hypervelocity alarm signal that obtains is effectively clear and definite.If with the boombox of guider 100 as voice-output device, then can be because of the reason of output power, make alarm signal can not hear clearly, therefore can adopt the FM lift-off technology to send on the vehicle-mounted radio, play back by automobile audio, its voice output power will be much larger than the output power of boombox, thereby the alarm effect is significantly improved.Wherein alarming voice is to record in advance and be stored in the storage unit 30, and engine map and geodata navigation application software and hypervelocity alarm submodule thereof provide the operation-interface of these voice suggestion data of visit.
Wherein, when above-mentioned guider 100 moves in system, owing to need constantly obtain its current location velocity information, judge to make timely and effectively, therefore navigation application software and submodule thereof hypervelocity alarm module or driver comprise at least one circular treatment program or interrupt service routine, with the position and the velocity information of continuous reception from 20 receptions of position signalling receiving element.In addition, owing to needing constantly the relatively magnitude relationship of the standard of the limited speed of the present speed of guider 100 and road, navigation application software and submodule hypervelocity alarm module thereof also comprise at least one circular treatment program, with the magnitude relationship of the standard of the limited speed of the present speed of continuous relatively guider 100 and road, the prompting of poster sound is informed in concurrent excess of export.This circular treatment program can be same program with the above-mentioned circular treatment program of obtaining position and speed information.
