The rapid increase in the number of logistics and express delivery has also brought about some safety issues, and some criminals have always wanted to transport some prohibited items through logistics. In order to more accurately detect prohibited items and reduce the workload of staff, Wuhan Aiwei has developed a set of special parcel passing container security inspection machines for express logistics. After the courier places the package on the conveyor belt, it is scanned by the machine's X-ray car, and the originally tightly packed package suddenly becomes transparent. The situation of the delivered items can also be clearly seen on the screen of the container security inspection machine. Through the detection of the special packaging container security inspection machine for express logistics, it can effectively prevent the outflow of dangerous goods such as firearms, ammunition, controlled knives, and drugs. Wuhan Aiwei Technology, as a high-tech private enterprise that produces and sells public safety inspection equipment, mainly produces security inspection products such as container security inspection systems, small truck security inspection systems, green channel quick inspection systems, and security inspection doors, X-ray machines, handheld detectors and underground detectors in public safety inspection equipment, as well as desktop security inspection devices for explosives, drugs, liquids, and vehicle bottom scanner systems and small explosion-proof barrels, Provide hardware equipment, software, services, and solutions for entrance security inspections for security service providers and government agencies of large enterprises and institutions around the world.
