Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Close diagram and specific embodiment, the present invention is expanded on further.
As shown in Figures 1 and 2, the moment opening car door resist technology that the present invention proposes includes industrial computer 3, and is arranged at
Car external environment detection device 1 outside industrial computer 3, also includes the passenger detection device 2 being arranged at outside industrial computer 3, also includes
It is arranged at the vehicle body self-locking device 4 outside industrial computer 3, also includes being arranged at alarm set 5 in the car outside industrial computer 3；
With reference to Fig. 1, detecting device and be connected with industrial computer 3 by circuit outside described car, described passenger detection device 2 passes through
Circuit is connected with industrial computer 3, and described vehicle body self-locking device 4 is connected with industrial computer 3 by circuit, alarm set in described car
5 are connected with industrial computer 3 by circuit；
Further, described car external environment detection device 1 uses video detector, based on picture signal treatment technology and meter
The advantage of the video detector of calculation machine vision technique is a lot, although video detector is affected relatively big by weather, but can use
The high sensitivity B/W camera of low-light (level) improves the effect of detection and segmentation.He can detect on a large scale and gather
To the multiple transport information of real-time and precise, analyze and draw the traffic data that we are required.Here primarily to obtain other cars
And the distance of pedestrian and speed, described video detector includes video capture and transport unit, Video Detection main frame, control
Device and detecting system software, it is possible to detect the practical situation of vehicle periphery, then by data transmission set, data are transmitted
To inner computer, inner computer Treatment Analysis draws pedestrian and the travel speed of other vehicles, distance and kinestate, meter
Calculate the time arriving car door, determine whether alarm set 5 and vehicle body self-locking device 4 in opening vehicle.Utilize vehicle image
The two-dimensional position of middle vehicle and some parameters of measured in advance calculate the actual three-dimensional position of vehicle, if a set time
Interval in shooting two width images, then can according to two width images calculate the actual three-dimensional position of vehicle obtain vehicle at this fixing time
Between displacement in interval, thus further determine that car speed；
Further, described passenger detection device 2 is internally provided with handle, and described handle is internally provided with condenser type sense of touch
Sensor, passenger detection device 2 is connected with industrial computer 3 by circuit respectively with car external environment detection device 1, and car external environment is examined
Survey device 1 and be used for detecting pedestrian and the speed of vehicle and distance, and realize forecast function according to the calculating of program, thus judge row
People and vehicle knock the probability of car door, and acquired results is delivered to passenger detection device 2, then by passenger detection device 2
The information of tactile sensor detection occupant's door opening, and control alarm set 5 and vehicle body in car by industrial computer 3 after being processed
Self-locking device 4；
Further, in described car, self-locking device is internally provided with clamp, alarm set 5 in vehicle body self-locking device 4 and car
Principle be to learn someone car door to be opened by condenser type tactile sensor, if learnt the most on inspection with pedestrian and other
Vehicle has the possibility of collision, then realize open locking function by the drive path between industrial computer 3 control handle and clamp；
Further, in described car, alarm set 5 is internally provided with siren, is realized occupant by siren
Prompting, notify occupant note preventing personnel outer with car and other pass through automobile crash；
With reference to Fig. 2, the frequency of the velocity sensor square-wave signal on self variator of usual automobile, at 0-200Hz, works as car
Speed drops to below 10km/h, when i.e. velocity sensor output frequency only has several hertz, and system start-up.After system start-up, need
Meet following two condition:
Condition one: in order to prevent other traffic participants from colliding with this car, rear view of vehicle situation need to be detected.According to stopping
Car sighting distance S, and in view of the most probable velocity of vehicle on real road, last rear monitoring distance value is 110m.Vehicle
The monitoring of both sides need to consider road width, and combines general vehicle commander and precision problem, draws value 3m.
Condition two: it has been determined that judge that vehicle and pedestrian have under the danger knocking car door, if passenger detection device 2 quilt
Triggering, i.e. have occupant to touch car door, system carries out further work automatically.
When two above precondition all reaches, in system, auto-lock function and alarm start.Alarm is sounded a buzzer,
Illustrate now owing to dangerous door lock has been locked.Carrying out locking door after the 1-2 second, system detects device 1 according to car external environment
Detected situation, determines whether the possibility knocked again.If without danger, door lock unlocks；In two premises, as long as
There is a premise to meet, all without there being follow-up reaction, but before occupant gets off, can detect the most dynamically
With or without the possibility knocked, without the possibility knocked, then door lock controller directly unlocks, and occupant can get off smoothly；Otherwise, the most again
The secondary judgement returning to condition one.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
