Description
Technical field
The present invention relates to public safety field, specifically a kind of safety detecting system and detection method.
Background technology
In the occasion that some are important, need to carry out safety check to the automobile entered, to guarantee that the automobile entered does not carry dangerous goods.And the automobile difficult point of whether carrying when dangerous goods detect is to the detection of automobile chassis.
At present; known automobile chassis foreign material detecting technique mainly contains two kinds; one is by completing manually; when automobile enters before important place; security personnel can take a slice reflective mirror to check the situation of automobile chassis usually; but because the impact of light and manual operation subjectivity are too large, different testing staff usually can be caused to draw different testing results, and the confidence level of result is also very not high.Another is the scanning utilizing image to carry out automobile chassis, it is a kind of vehicle chassis safety check system based on machine vision, but this product only carries out image taking to automobile chassis, and carry out picture synthesis by computer, again by manually going to check whether there is foreign matter, simultaneously because the speed in vehicle traveling process differs, easily cause the distortion of image, affect the Checking on effect of human eye to image, defect maximum within the system is in addition exactly can not effectively detect the dangerous goods be blocked, potential threat is caused to public place, therefore this system still cannot practical requirement.
Summary of the invention
For solving the problems such as accuracy that prior art detection system exists when checking automobile chassis foreign matter is not high, the invention provides a kind of safety detecting system and detection method.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of safety detecting system, this safety detecting system is arranged in detection zone, detection zone is provided with and enters automatically-controlled door, leave automatically-controlled door, heavily examine automatically-controlled door and safety stop lever, this safety detecting system comprises for exporting the control module of control signal to information analysis process, and control module controls the duty entering automatically-controlled door, leave automatically-controlled door, heavily examine automatically-controlled door and safety stop lever of detection zone; For the automobile that will enter detection zone is carried out head mug, extract the number-plate number and license plate information is sent to control module car plate detect identification module; For carrying out chassis quick stereo image scanning to the automobile being in detection zone, detect the foreign matter in chassis image and the hazard level of foreign matter defined the level and information is passed to the chassis foreign bodies detection module of control module; For carrying out mug to the side of the automobile being in detection zone and extracting the human face image information of driver, information in fingerprint information is passed to the biological characteristic recognition module of control module.
Described safety stop lever is used for restriction or releasing vehicles enters detection zone;
The described automatically-controlled door that enters is for restriction or releasing vehicles target approach place;
The described automatically-controlled door that leaves leaves detection zone for automobile;
The automobile that described heavy inspection automatically-controlled door is used for leaving through leaving automatically-controlled door detection zone enters detection zone again.
The detection method of this safety detecting system, comprises the following steps:
1) car plate detection identification module is taken pictures to automobile head thus extracts license plate information and send license plate information to control module, the license plate information of this license plate information and storage compares by control module, if qualified, then control module controls safety stop lever lifting, and releasing vehicles enters detection zone;
2) quick stereo image scanning is carried out on the chassis of foreign bodies detection module in chassis to the automobile entering detection zone, and the foreign matter detected in the image of chassis and the hazard level of foreign matter is defined the level and Detection Information is passed to control module, control module is by the information of reception and the information comparison stored, and produce three kinds of output signals: completely qualified, carry out next-step operation; Completely defective, then control to leave automatically-controlled door and open, make automobile leave detection zone; Uncertain, then control to leave automatically-controlled door, heavily inspection automatically-controlled door and open and safety stop lever lifting, automobile reenters detection zone by this twice automatically-controlled door and safety stop lever and heavily examines;
3) biological characteristic recognition module carries out mug to the side of automobile, then the human face image information of driver and information in fingerprint is gathered and by information transmission to control module, information and the information stored are carried out Intelligent Matching and identification by control module, produce three kinds of output signals: completely qualified, then control to enter automatically-controlled door to open, releasing vehicles enters; Completely defective, control to leave automatically-controlled door and open, make automobile leave detection zone; Uncertain, then control to leave automatically-controlled door, heavily inspection automatically-controlled door and open and safety stop lever lifting, automobile reenters detection zone by this twice automatically-controlled door and safety stop lever and heavily examines.
Information comparison in described control module adopts similarity whether qualified to judge, the qualified information being about to information and the storage gathered compares, obtain both similarities, if similarity is completely qualified when being greater than a certain setting value, similarity is completely defective when being less than a certain setting value, fall between as uncertain, need heavily to examine.
Beneficial effect: the present invention real time automatic detection can go out the foreign matter Carriage of automobile chassis, and according to the effective steer motor travel route of testing result, in advance the automobile carrying dangerous material is kept outside of the door, guarantee the safety of target place, customs's drugs etc. are detected and prevents the attack of terrorism significant.
