step two: a user enters a security check channel, walks in the security check channel according to the prompt of a security check system, and at the moment, a non-inductive scanning back security check module integrated on the back channel wall transmits millimeter wave terahertz signals and completes the receiving operation of characteristic signals, completes the acquisition and digital processing of multi-direction full-three-dimensional security check information of the back and the side of the user and the like, and transmits the information to a host system for processing and imaging;
step three: then, a non-inductive scanning front-side security inspection module integrated on a front-side channel wall transmits millimeter wave terahertz signals and completes the receiving operation of characteristic signals, multi-directional full-three-dimensional security inspection information acquisition and digital processing of the front side, the side and the like of a user are completed, the security inspection information is transmitted to a host system for processing and imaging, the non-inductive security inspection process of the user is completed, and the user does not need to stay in the process;
step four: stopping advancing when the user walks to a waiting line in front of the automatic translation door in the channel according to the prompt step, and recognizing and verifying the face information at the face recognition module according to the system prompt;
step five: before the user waits at the face recognition module, the host system finishes the security check process and displays the user security check information on the display equipment; the safety inspection information shows that the suspicious object is not carried and the face identification verification is passed, the automatic translation door positioned at the outlet is opened to allow the user to pass, and the user completes the whole process of the non-sensitive safety inspection; if the security inspection information shows that the user carries the suspicious object or the face identification is not passed, the user cannot pass, and the staff is informed to process the condition that the suspicious object or the face information carried by the user is inconsistent, so that the security inspection process is completed.
