Abstract
The invention discloses an automobile safety multi-functional speed limiting warning device, comprising a globe positioning system (GPS) receiver, a micro inertial navigator, a personal computer (PC) industrial personal computer, a display and an alarm, wherein a road map database is stored in the PC industrial personal computer; the signal input end of the PC industrial personal computer is connected with the signal output ends of the GPS receiver and the micro inertial navigator respectively; the PC industrial personal computer receives vehicle running speed information obtained by the GPS receiver and the micro inertial navigator and compares the vehicle running speed information with the road speed limiting information in the road map database; and the alarm is connected with the PC industrial personal computer for sending out warning information. The automobile safety multi-functional speed limiting warning device solves the problem of limiting warning of the automobile speed limiting warning device under the condition that signals cannot be received in tunnels or cities with dense buildings, the structure is simple; the automobile speeding judgement is accurate and reliable, so that the running safety and reliability of automobiles are improved.
Description
Technical field:
The present invention relates to a kind of automobile driving speed automatic monitoring alarm, the automobile speed limit that especially is fit under warning of high safe occasion automobile speed limit and harsh environment or the enclosed signal shielding environment is reported to the police.
Background technology:
Along with the raising of living standards of the people, the automobile popularity rate is also increasingly high, but thing followed traffic accident is also more and more.Add up according to authoritative department; Annual surpass half the traffic accident and result from overspeed driving car, so traffic department, is provided with the F-Zero of running car and the minimum speed per hour on the express highway according to the situation in each highway section; And to different road conditions, the restriction of moving velocity is also different.At present, domestic and international more employing radar velocity measurement device is implemented to test the speed to the driving vehicle that exeeds the regulation speed, and the combination scene is tested the speed, intercepted and measure such as punishment, and control and punishment joy riding personnel safeguard the unimpeded and safety traffic of road.The hypervelocity phenomenon through traffic department real-time monitoring and test the speed and obtain certain alleviation, but speed measuring device is the part highway section, it is faster to cause the non-highway section of testing the speed to drive speed, can not stop fully because the traffic accident that hypervelocity causes.
Summary of the invention:
The objective of the invention is to present different highway sections speed limits differently, the alarm of actv. hypervelocity or low speed driving can in time be provided in different highway sections, make vehicle safety traffic as far as possible.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of automotive safety multi-function speed-limiting warning device; It is characterized in that: comprise GPS receiver, micro-inertial navigation appearance, PC industrial computer, telltale and annunciator; Contain the road-map-data storehouse at described PC industrial computer internal memory; Described PC industrial computer signal input part is connected with the signal output part of described GPS receiver and micro-inertial navigation appearance respectively; Described PC industrial computer receive running velocity information that said GPS receiver and micro-inertial navigation appearance obtain and with the road-map-data storehouse in road speed-limiting messages relatively, described annunciator is connected with described PC industrial computer and is used to send alarm message.
Described GPS receiver receives the signal that sends from the navigation gps satellite, comprising: vehicle location, speed and direction, and be responsible for carrying out transfer alignmeut to the micro-inertial navigation appearance.
The micro-inertial navigation appearance comprises three silicon micro-gyroscopes and three quartz accelerometers, and three silicon micro-gyroscopes and three quartz accelerometers distribute along orthogonal three spatial axes respectively.
Described speed-limiting messages comprises go minimum limit value and ceiling value.
The GPS receiver uses XW-RTK OEM module, and quartz accelerometer uses the XW-AS1920 quartz accelerometer, and silicon micro-gyroscope uses the CRG20 micromechanical gyro.
The present invention relates to a kind of automotive safety multi-function speed-limiting warning device, through forming by GPS receiver, micro-inertial navigation appearance, map display, map data base, PC104 industrial computer, annunciator.
Principle of work: in the vehicle ' process, when gps satellite signal is better, use GPS to carry out navigator fix; Vehicle obtains location information and velocity information; And can real time information be presented on the read-out, in the car speed information and date storehouse that obtains through GPS in advance the travel velocity information of storage compare, if be higher than the ceiling value of moving velocity; Then annunciator gives the alarm, and reminds hypervelocity.If be lower than the minimum limit value of moving velocity, then annunciator gives the alarm, and prompting speed is lower, notes keeping to the side, and plays Warning light.
If gps satellite signal very a little less than; Even when not having, sail between tunnel, culvert, the high-rise building, when the dense woods are blocked such as vehicle, automatically switch to inertial navigation pattern through system this moment; Start the micro-inertial navigation appearance; And obtain position, the velocity information of vehicle through the micro-inertial navigation appearance, may be displayed in the car speed information and date storehouse that obtains through the micro-inertial navigation appearance on the telltale in advance that the velocity information of storage compares, if be higher than the ceiling value of moving velocity; Then annunciator gives the alarm, and reminds hypervelocity.If be lower than the minimum limit value of moving velocity, then annunciator gives the alarm, and prompting speed is lower, notes keeping to the side, and plays Warning light.
Advantage of the present invention is: will no matter better perhaps not have under the condition of satellite-signal at satellite-signal, and can in time remind navigating mate to note Vehicle Speed, and guarantee traffic safety.

The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done further explanation:
The objective of the invention is to present different highway sections speed limits differently, the alarm of actv. hypervelocity or low speed driving can in time be provided in different highway sections, make vehicle safety traffic as far as possible.
The present invention relates to a kind of automotive safety multi-function speed-limiting alarm method and device; Through forming by GPS receiver 1, micro-inertial navigation appearance 2, telltale 6, PC104 industrial computer 3, annunciator 5; Contain the road-map-data storehouse at PC industrial computer internal memory; PC industrial computer 3 signal input parts are connected with the signal output part of GPS receiver 1 with micro-inertial navigation appearance 2 respectively; PC industrial computer 3 receive running velocity information that GPS receivers 1 and micro-inertial navigation appearance 2 obtain and with the road-map-data storehouse in road speed-limiting messages relatively, described annunciator 5 is connected with described PC industrial computer 2 and is used to send alarm message.
Principle of work: in the vehicle ' process, when gps satellite signal is better, use GPS to carry out navigator fix; Vehicle obtains location information and velocity information; And can real time information be presented on the read-out, in the car speed information and date storehouse that obtains through GPS in advance the travel velocity information of storage compare, if be higher than the ceiling value of moving velocity; Then annunciator gives the alarm, and reminds hypervelocity.If be lower than the minimum limit value of moving velocity, then annunciator gives the alarm, and prompting speed is lower, notes keeping to the side, and plays Warning light.
