BGV3000 passenger vehicle inspection system adopts radiation fluoroscopy scanning imaging technology, which can perform real-time online scanning and imaging inspection of various passenger vehicles. The system is mainly composed of a ray source system, detector system, gantry structure and radiation protection device, vehicle transportation system, power distribution and control system, safety monitoring system, vehicle imaging inspection system workstation and software. The ray source is installed on the top of the inspection channel, and the detector is installed on the bottom of the inspection channel. During inspection operation, the inspection system is fixed, the inspected vehicle is transported through the inspection channel at a constant speed through the conveying device, the radiation source is irradiated from the top of the inspected vehicle, the detector array received signal, then a scanned image will present on image inspection platform in real-time.
