a) before actual work, all shapes of the forbidden articles known nowadays which can be true are stored in the storage module, so that the image comparison unit in the central processing module can be conveniently read in the later security check process;
b) the working personnel control the central processing module to supply power to the first motor, the display module and the alarm module through the control equipment, so that the first motor, the detection and identification mechanism, the display module and the alarm module start to work, security inspection objects are sequentially placed on the upper surface of the conveyor belt, the conveyor belt is driven to rotate under the work of the first motor, the objects to be detected are conveyed into the security inspection bin, after the objects to be detected enter the security inspection bin, the detection and identification mechanism detects the detected objects, the detected objects are subjected to penetration detection through X-rays, detected color images are transmitted to the central processing module, and the detected images are transmitted to the display module by the central processing module to be displayed for the working personnel to check;
c) the central processing module passes through the image recognition unit and discerns the colour image profile that detects article, all article colour profiles in detecting article are drawed, and compare all dangerous goods profile images of storage in the storage module, when contrast have article shape and storage module in the detection article in the dangerous goods shape the same, central processing module just gives alarm module power supply, make alarm module report to the police, central processing module divide into three warning grade with dangerous goods, do respectively: primary alarm, medium alarm and high alarm;
d) when the central processing module identifies that the outline image of the detected article is lower than the danger coefficient stored in the storage module or the outline of the article needing further detection is similar or identical, the central processing module determines the article as a primary alarm, the central processing module supplies power to the alarm module at the moment, the alarm module works, and the buzzer starts to give an alarm in a loud mode;
e) when the central processing module identifies the outline image of the detected object and is the same as the outline of a dangerous object stored in the storage module, the central processing module ranks the object to be middle-level alarming, the central processing module supplies power to the alarming module to enable the alarming module to start working, the alarming module starts high-sound alarming through the buzzer and simultaneously sends information to the mobile communication terminal of the security manager through the signal sending unit, and meanwhile, the security manager quickly reaches a security inspection site;
f) when the central processing module identifies the outline image of the detected object, the outline image is the same as the outline of the high-risk object stored in the storage module, or the detection identification mechanism identifies the high-radiation object, the central processing module sets the object to be high-grade alarm, supplies power to the alarm module, enables the buzzer to start to give a high-sound alarm and close the signal sending unit to notify security management personnel to arrive, simultaneously, the central processing module supplies power to the explosion-proof sealing mechanism, the explosion-proof sealing mechanism rapidly seals the entrances and exits at the left side and the right side of the security inspection bin, so that the hazardous object is sealed in the security inspection bin, the security inspection object is prevented from being robbed by the personnel carrying the hazardous object, the later-stage personnel can operate the control equipment, controls the explosion-proof sealing mechanism to cancel the sealing of the entrances through the central processing module, takes out the security inspection object, also prevents the hazardous object from exploding, and places the hazardous object in the security inspection bin, if the detected article explodes, the harm caused by the explosion is reduced to the minimum.
8. The security inspection method based on image recognition according to claim 7, wherein: staff's accessible operation controlgear, the corresponding warning grade of different hazardous articles of artificial settlement, according to actual need, improve the accuracy of reporting to the police.
9. The security inspection method based on image recognition according to claim 7, wherein: when the staff through the display module people for observing not typeeing storage module forbidden articles, staff's accessible controlgear's control panel artificially triggers the warning, still respectively is: primary alarm, medium alarm and high alarm.
