In the embodiment of the invention, the article identification level corresponding to each preset passenger flow rate interval is stored in the electronic equipment, wherein each preset passenger flow rate interval is not overlapped, and the article identification level corresponding to the higher the upper limit passenger flow rate of the passenger flow rate interval is, the lower the upper limit passenger flow rate is. For example: the preset pedestrian volume interval comprises: the article identification system comprises a people flow interval 1 '[ 0 person/min-20 person/min ]', a people flow interval 2 '[ 21 person/min-50 person/min ]', a people flow interval 3 '[ 51 person/min-100 person/min ]', a people flow interval 4 '[ 101 person/min-200 person/min ]', and a people flow interval 5 '[ 201 person/min- + ∞ ]', wherein the article identification grade corresponding to the people flow interval 1 is 5, the article identification grade corresponding to the people flow interval 2 is 4, the article identification grade corresponding to the people flow interval 3 is 3, the article identification grade corresponding to the people flow interval 4 is 2, and the article identification grade corresponding to the people flow interval 5 is 1.

and the detection module is used for controlling the X-ray security inspection machine corresponding to each security inspection port and detecting whether contraband exists in the acquired X-ray image by adopting the identification level of the target object corresponding to the security inspection port.
7. The device according to claim 6, wherein the obtaining module is specifically configured to determine, for each security inspection opening, a flow rate of people corresponding to the security inspection opening according to the number of people detected by the security inspection opening camera corresponding to the security inspection opening within a set time period; or aiming at each security inspection port, determining the flow of people corresponding to the security inspection port according to the number of packages detected by the X-ray security inspection machine corresponding to the security inspection port within a set time.
8. The apparatus of claim 6, wherein the apparatus further comprises:
the first judgment module is used for judging whether the target article identification level corresponding to the X-ray security inspection machine is the highest article identification level or not if no contraband article exists in the acquired X-ray image, and triggering the second judgment module if the judgment result is negative;
the second judgment module is used for judging whether an article with the similarity or the confidence coefficient larger than a set threshold exists in the X-ray image, and if so, the rechecking module is triggered;
and the rechecking module is used for controlling the X-ray security inspection machine to recheck whether contraband exists in the X-ray image by adopting the highest article identification level.
9. The apparatus of claim 8, wherein the apparatus further comprises:
and the information acquisition module is used for controlling an information acquisition camera corresponding to the X-ray security inspection machine to acquire a first image of a package corresponding to the X-ray image and/or acquire a second image of a target person carrying the package if the similarity or confidence coefficient of the X-ray image to the contraband is larger than a set threshold value.
10. The apparatus of claim 9, wherein the apparatus further comprises:
and the tracking module is used for determining that contraband exists in the X-ray image if the X-ray image is subjected to rechecking, and sending the first image of the package and/or the second image of the target person carrying the package to a monitoring system so that the monitoring system tracks the package and/or the target person carrying the package.
