Description
Technical field
The present invention relates to intelligent collision early warning system more particularly to a kind of right sides based on millimeter wave on the right side of a kind of commercial vehicle
Intelligent collision pre-warning management system and working method.
Background technique
In urban highway traffic, oversize vehicle Frequent Accidents are in crossing, wherein mainly in the majority to turn right and cross collision.
Since the blind area of oversize vehicle is larger, if excessive velocities or turning radius are too small when turning, major traffic accidents easily occur.Especially
It is that the Heavy Duty Commercial Cars such as bus, harmful influence vehicle, engineering truck shuttle daily in urban road, with car, electric bicycle,
Pedestrian comes into contacts with, and the degree of social concern of traffic safety is very high.Vehicle is commonly left rudder vehicle at present, and wherein the right-hand rotation of large car is blind
Area is referred to as " taking life blind area by force ", and driver once diverts one's attention when driving vehicle, is easy to produce to roll and dies occurrences in human life event, gives family, society
Significant damage and baneful influence can be brought.
In order to prevent traffic accident caused by oversize vehicle is turned right, it has been proposed that being taken the photograph in vehicle right front installation
As the improved method of head, although right lateral side encounters when this method can turn right to vehicle pedestrian, vehicle, barrier etc. carry out
Real-time monitoring simultaneously can carry out warning reminding in time, play good accident prevention effect, but the above method to a certain extent
Camera belong to optical device, the situation good suitable for weather, sighting distance is unaffected, once encounter bad weather, it is such as big
When rain, dense fog, big snowy day, the image monitoring effect of camera will have a greatly reduced quality, it is difficult to meet the needs of vehicle safe driving.
Meanwhile the driver safety consciousness of individual Heavy Duty Commercial Cars is not strong, drives over the speed limit, drives the Problems such as divert one's attention relatively dashes forward
Out, and conventional method can not the information such as the speed of service, track to vehicle acquired and obtained in real time, it is difficult in time to driving
The bad steering behavior of member carries out early warning prompting.
Summary of the invention
Goal of the invention: in view of the above shortcomings of the prior art, the object of the present invention is to provide a kind of right sides based on millimeter wave
Side intelligent collision pre-warning management system and working method, it is commercial under heavy rain, heavy snow, dense fog poor weather to solve the prior art
Vehicle right-hand rotation blind area can not effectively monitor, right front crosses that collision can not early warning and right-hand rotation driving behavior data can not be real-time in time
The problem of acquisition.
Technical solution: the present invention is based on the right side intelligent collision pre-warning management systems of millimeter wave, including early-warning apparatus ontology, milli

Loudspeaker 4 is installed on outside driver's cabin, and when six axis gyroscopes, which determine, turns right, loudspeaker 4 is alert by voice mode
Show and pass by other traffic participants, such as " engineering truck is turned right, it is noted that safety ".
Main computer unit realizes the control management and data-signal output of system each unit, and hazard recognition target.Monitoring
To when turning right, pass through other traffic participants of speaker alarms in the form of high pitch；It is right to monitor to trigger the vehicle based on millimeter wave
When the collision-proof alarm rule of side, driver is reminded by alarm and display screen with acoustooptic form, it is synchronous by speaker alarms its
His traffic participant；When right-hand rotation, main computer unit uploads data to management platform according to treaty rule.
Management platform is using the system platform for meeting Ministry of Communications's global position system communication protocol standard, real-time reception, note
Record, inquiry, each module working condition of management pre-warning management system and vehicle traveling information, vehicle, which are turned right, travels detailed data, and
Stored the inquiry in order to vehicle right-hand rotation operation data and statistical analysis；In addition, management platform can be in system initialization
System parameter is set according to actual needs.
These modules and unit cooperate realization to transport the real-time monitoring of commercial vehicle right-hand rotation blind area, audible and visual alarm and vehicle jointly
The upload of row data.
When automobile in motion, the intrinsic six axis gyrosensor real-time measurement vehicle yaw of early-warning apparatus, inclination when
Rotational angular velocity transmits magnitude of angular velocity to main computer unit in real time.Every 10 milliseconds of measurements are primary, continuous measurement 5 times, if 5 times
The threshold value that measurement result is turned right more than six axis gyroscopes, it is determined that vehicle is right-hand bend state.It is measured according to real vehicle, six
Axis gyroscope right-hand bend threshold settings are 25 degree/s.
The display screen for being built-in with alarm is installed in driver's cabin, is reminded and is driven in the form of alarm sound and the light of transformation
Member；Loudspeaker 4 is installed on outside vehicle, and when six axis gyroscopes, which determine, turns right, speaker alarms pass by other traffic participants, than
Such as " engineering truck is turned right, it is noted that safety ".
