摘要： A vehicle detection system includes a transverse detector arm, two vertical detector arms, a radiation source, a plurality of transverse detectors, and a plurality of vertical detectors. The transverse detector arm may be disposed on the ground. Two vertical detector arms are disposed at both ends of the transverse detector arm. The radiation source is located above the transverse detector arm. A plurality of transverse detectors are disposed within the transverse detector arm and are laid along a length direction of the transverse detector arm for receiving ray emitted by the radiation source. The plurality of vertical detectors are symmetrically disposed on the two vertical detector arms, and each of the vertical detectors is disposed towards a center point of the radiation source for receiving ray emitted by the radiation source.

摘要： A vehicle pulling device, a system for passing a vehicle in two modes, and an inspection system for scanning a vehicle by radiation are disclosed. The vehicle pulling device comprises a movable chassis disposed in a passage for a vehicle and being movable in a first direction; and a support beam disposed to the movable chassis and being rotatable between a first position and a second position. In the first position, the support beam is located substantially in a second direction substantially perpendicular to the first direction, such that wheels of the vehicle are interacted with the support beam of the vehicle pulling device so that the vehicle is pulled to pass through the passage; and in the second position, the support beam is located substantially parallel to the first direction such that the wheels of the vehicle are not interacted with the support beam of the vehicle pulling device so that the vehicle travels by itself to pass through the passage. Therefore, when the vehicle does not need to be pulled, the support beam is rotated to the second position, and the vehicle travels by itself to pass through the passage. When the support beam is rotated to the first position, the vehicle pulling device can pull the vehicle to pass through the passage.
摘要翻译：公开了一种车辆牵引装置，以两种模式通过车辆的系统和用于通过辐射扫描车辆的检查系统。车辆牵引装置包括设置在车辆通道中并可沿第一方向移动的可移动底盘; 以及支撑梁，其设置在可动底盘上并且可在第一位置和第二位置之间旋转。在第一位置，支撑梁基本上位于基本上垂直于第一方向的第二方向上，使得车辆的车轮与车辆牵引装置的支撑梁相互作用，使得车辆被拉动以通过通道 ; 并且在第二位置，支撑梁基本上平行于第一方向定位，使得车辆的车轮不与车辆牵引装置的支撑梁相互作用，使得车辆自身行进通过通道。因此，当车辆不需要拉动时，支撑梁旋转到第二位置，车辆自身行进通过通道。当支撑梁旋转到第一位置时，车辆牵引装置可以拉动车辆通过通道。
