    摘要： The present disclosure provides a laser speed measuring method, control device and a laser velocimeter, and relates to the technical field of security inspection. The laser speed measuring method comprises the steps of: acquiring detection data within a predetermined detection angle range in a plurality of paralleled horizontal planes having different heights, from a plurality of laser rays detected towards a road extending direction in the horizontal plane; acquiring three-dimensional point cloud data according to the detection data; determining a position of a measured object in the road extending direction according to the three-dimensional point cloud data; and determining a speed of the measured object according to the position change of the measured object along the road extending direction at different timing.

    摘要： The present disclosure relates to a security scanning inspection system and method. The security scanning inspection system comprises a detector, a scanning device and a controller, wherein the detector is configured to detect a protective attribute of an object to be inspected; the scanning device is movably arranged and the scanning device is configured to emit a scanning ray during movement to perform a security scanning inspection on the object to be inspected, the scanning device comprising at least two working modes, wherein a dose of a scanning ray in each working mode is different from a dose of a scanning ray in any other working modes; and the controller configured to select a working mode of the scanning device according to the protective attribute of the object to be inspected detected by the detector.

    摘要： The disclosure relates to a traction device and a traction method. The traction device includes: a support chassis; a swing arm, one end of the swing arm is rotatably connected to the support chassis by a rotating shaft such that the swing arm can be switched in a retracted state and a deployed state, wherein the swing arm in the deployed state is adapted to drive the wheel of the vehicle to rotate and tow the vehicle; a driving mechanism, connected to the swing arm, wherein the driving mechanism is capable of driving the swing arm to horizontally rotate around the rotating shaft to switch the swing arm between the retracted state and the deployed state; and a rolling assembly, disposed on a side of the support chassis and being capable of preventing the wheel from contacting with the side of the support chassis when the vehicle is towed.
