Embodiment Construction

[0025] The following will refer to the attached figure 1 and 2 The structure and working process of the vehicle inspection apparatus as an exemplary embodiment of the present invention will be described in detail.

[0026] The vehicle rapid inspection equipment of the present invention includes a channel 14 for the passage of inspected moving objects such as containers, a radiation source cabin 9 with a scanning imaging device installed therein, and a rapid response for detecting vehicles entering the channel. Light curtain switch 2 and ground sensing coil 3, speed measuring radar 7 for measuring the moving speed of the vehicle, and a control room (not shown). The quick-response light curtain switch 2 is installed on the installation columns on both sides of the channel, and the ground sense coil 3 is buried at the channel entrance (attached figure 2 Near the right side of the ground surface is used as the first switch of the vehicle entrance. These two devices are used in ...

Abstract

The invention discloses a device used for the imaging and checking to a moving target rapidly, comprising a channel for the moving target to pass through; a scan imaging device which images the moving target by emitting radiant flux to the moving target passing through the channel and then checks the moving target; a first detecting unit which is used for judging whether the moving target enters the channel and counting the number of the moving target entering the channel; a second detecting unit which is used for measuring the moving speed of the moving target in the channel; and a control unit which controls the second detecting unit to detect the moving speed of the moving target according to the detecting signals received from the first detecting unit about the moving target entering the channel, and controls the scan imaging device according to the measuring result of the second detecting unit, so that the scan imaging device emits radiant flux at a frequency corresponding to the speed of the moving target, thereby checking the moving target.

Description

technical field [0001] The invention relates to the scanning and imaging process of a moving target, especially the scanning and imaging process under the condition that the target moves at a non-uniform speed and requires incomplete fast imaging. In particular, the present application relates to a device and method for rapid imaging inspection of a moving target. Background technique [0002] Equipment for inspecting vehicles using high-energy rays is a typical example of equipment for imaging inspection of moving objects. In the equipment that uses high-energy rays to inspect vehicles, it is usually used that the driver and passengers leave the vehicle, and the vehicle to be inspected is dragged by the drag device to move at a constant speed, and the radiation source uses a fixed frequency to scan and image the entire vehicle. The entire inspection takes several minutes, and the equipment cost is high. Vehicle inspection rates are low. [0003] WO2005098400 discloses an...
