The security inspection machine 2 comprises a conveying device 2-1, a security inspection cavity 2-2 and an operation center 2-3, wherein the conveying device 2-1 conveys articles to be security inspected to pass through the security inspection cavity, X-ray images of the articles, such as an X-ray generating device and a detector, obtained through a transmission imaging technology are arranged in the security inspection cavity, and then the types of the articles are judged according to X-ray imaging characteristics, such as shapes and the like, in the images through an intelligent image judging module on the operation center 2-3, so that contraband articles are identified.
In this embodiment, the conveying assembly 1 and the conveying device 2-1 of the security inspection machine 2 are both belt conveyors, and include motors, electric drums, belts, bend drums, and deviation-adjusting drums, the belt conveyors can be driven by the motors to rotate forward and backward, and in a working state, the belt conveyors of the conveying assembly 1 and the belt conveyors 2-1 of the conveying device of the security inspection machine 2 have the same conveying direction.
In the present embodiment, the trace species detection unit 3 is located in a gap between the transport unit 1 and the transport unit 2-1 of the security inspection machine 2, and this gap also serves as a wiping path for the trace species detection unit 3. The width of the wiping channel is more than or equal to 5mm and less than or equal to 200 mm. The conveying assembly 1, the trace substance detection assembly 3 and the conveying device 2-1 of the security inspection machine 2 are sequentially supported end to end but independently spliced, and the upper planes of the conveying assembly 1, the trace substance detection assembly 3 and the security inspection machine are positioned on the same horizontal plane, so that express delivery, package, products and the like can smoothly pass through the conveying device. The trace species detection assembly is comprised of one or more wipe sample trace species detection devices 4 (simply "wipe detection devices") which may include one or more wipe sample sites 5.
When the trace substance detecting assembly is also provided with a conveying structure which is consistent with the conveying direction of the conveying assembly or the conveying device of the security inspection machine, the part should be regarded as being distinguished as a part of the conveying assembly according to the effect.
In the present embodiment, as shown in fig. 2, the trace substance detecting assembly 3 includes 7 wiping detection devices 4 arranged side by side along a gap of 80mm between the conveying device 2-1 and the conveying assembly 1, the wiping detection device 4 includes 3 wiping sampling points 5 arranged side by side, each of which includes a test paper, a detection sensor, and a detection body, and 1 data processing and control module. The data processing and control module is used for receiving and analyzing the detection data of the wiping sampling points, transmitting the analysis results of the detection data to the operation center 2-3 of the security inspection machine, and distributing work tasks for detection of the detection sensors on the wiping sampling points and updating of test paper. The detection sensor is a trace substance detection device based on a fluorescence spectrum technology, an ion migration technology, a Raman spectrum technology, a mass spectrometry technology, a biological sensing technology, an MEMS sensing technology and the like. Typically, the analysis results of the detection data of the wiped sample points include information on the type and/or confidence of the trace substance. In one embodiment, when the analysis result of the detected data of the wiping sampling point is judged to be forbidden substances, the operation center also displays a warning prompt. The X-ray security inspection data utilizes an intelligent algorithm on the operation center to carry out target detection and identification, and information comprising the types and/or confidence degrees of contraband is output in an identification result. In one embodiment, contraband identification is performed for a deep learning based target detection algorithm. The operation center can fuse the X-ray security inspection data and the wiping trace detection data for further analysis so as to improve the identification accuracy of contraband and/or contraband substances such as explosives, narcotics and/or explosives.
The wiping detection device 4 is arranged in an array, and a plurality of wiping detection devices are arranged along the vertical direction of the article conveying direction to ensure that the articles can be wiped and sampled regardless of the position of the belt.

The wiping detection device 4 is composed of a plurality of wiping sampling points 5 in order to enable continuous operation of wiping sampling. Because the wiping sampling point needs several seconds of time for detection after sampling every time, the sampling operation can not be carried out in the period of time, in order to ensure continuous operation, a plurality of wiping sampling points are set as a unit group, and each wiping sampling point works in turn under the control of the data processing and control module, so that the detection continuity is ensured. The number and arrangement of the wiping sample points 5 in the wiping detection device 4 are set according to actual conditions, and may be a single-row arrangement as shown in the figure or a multi-row arrangement.

Two ends of the test paper are fixed on two output shafts of the stepping motor on the detection machine body in a coiling mode, one is used as a feeding shaft, the other is used as a pulling shaft, the support piece supports the test paper between the feeding shaft and the pulling shaft, and the three are tensioned to enable the test paper to be in a tensioning state. The test paper which is not wiped is rolled on the feeding shaft at one end, when the test paper feeding device works, the two stepping motors are linked under the control of the data processing and control module, the functions of tensioning, initially winding and conveying the sampling test paper are achieved, and the wiped sampling test paper is rolled on the pulling shaft at the other end. The direction of transport of the test strips is preferably aligned with or opposite to the direction of transport of the articles, i.e. the direction of transport of the transport assembly.
The detection sensor detects the test paper of the wiped object to obtain the detection data of the trace substance on the test paper of the wiped object, and the position of the sensor is adjusted according to the type and the requirement of the sensor, for example, the position of a wiping point can be detected in situ, or the test paper after wiping can be detected after being rolled forward for a certain distance. In general, each time an article passes through the trace substance detection assembly, the test paper contacting with the article is assigned a detection task by the data transmission and control module, and the test paper of the rest wiping sampling points is updated, so as to prevent the test paper contaminated at the wiping sampling point from entering a subsequent detection procedure and interfering with a detection result.
In this embodiment, a trigger sensor for triggering the operation of each part on the trace substance detection assembly is also optionally provided.
Taking security check of express packages as an example, in this embodiment, the express packages move along the conveying direction through the belt conveyor 2-1 of the security check machine 2 to obtain security check X-ray images of the express packages and articles in the express packages, and then reach the conveying assembly 1 through the wiping sampling device 3. In practical application, the sequence of passing the express packages through the security inspection machine and the trace substance detection assembly is not limited.
