图6是本发明实施例的车辆检查系统的控制示意图,车辆检查系统包括分段式车辆拖动系统,其中分段式车辆拖动系统包括两个拖动装置,如图6所示,所述第一拖动装置111设有第一传感器1114,该第一传感器1114设置在车辆前轮离开位置的下降沿,用于车辆前轮离开第一拖动装置111时发出信号,所述第二拖动装置112上设有第二传感器1124,用于在车辆前轮行进到刚好与第二拖动装置112接触的位置时发出信号;6 is a schematic diagram of control of a vehicle inspection system according to an embodiment of the present invention. The vehicle inspection system includes a segmented vehicle drag system, wherein the segmented vehicle drag system includes two drag devices, as shown in FIG. The first drag device 111 is provided with a first sensor 1114 disposed at a falling edge of the vehicle front wheel leaving position for signaling when the front wheel of the vehicle leaves the first drag device 111, the second drag The second device 1124 is disposed on the moving device 112 for transmitting a signal when the front wheel of the vehicle travels to a position just in contact with the second drag device 112;
控制器控制所述第一推动件1113以第一速度推动车辆后轮,当收到第一传感器1114发出的信号时控制第二细长牵引件1122即第二链条移动,使第二推动件1123从开始移动到所述第二推动件1123与车辆前轮接触的时间间隔与第一传感器1114发出信号到第二传感器1124发出信号的时间间隔相等,并且第二推动件1123以所述第一速度与车辆前轮接触并推动车辆前轮,以保持车辆的匀速运行状态。The controller controls the first pushing member 1113 to push the rear wheel of the vehicle at a first speed, and controls the movement of the second elongated pulling member 1122, that is, the second chain when receiving the signal from the first sensor 1114, so that the second pushing member 1123 The time interval from the start of movement to the second pusher 1123 in contact with the front wheel of the vehicle is equal to the time interval at which the first sensor 1114 signals a signal to the second sensor 1124, and the second pusher 1123 is at the first speed. It contacts the front wheel of the vehicle and pushes the front wheel of the vehicle to keep the vehicle running at a constant speed.
本发明通过在前后分段式拖动装置上合理布置第一传感器1114和第二传感器1124的位置以及第二拖动装置的第二细长牵引件的初始位置,进而确定第一传感器1114、第二传感器1124以及第二推动件1123之间的位置关系,并通过控制器前后精确控制两段拖动装置上的推动件的运动,使车辆可以匀速通过两段扫描装置,不需要改变射线检查系统中X射线发生装置的出束频率,也不用考虑车轮直径调节加减速时间,减少了出束和探测系统控制的复杂性,提高系统的检测效率。另外,设置于第一拖动装置和第二拖动装置之间的射线检查系统,其射线源发出的射线可以经过第一拖动装置和第二拖动装置之间的空隙,并被探测器接收,这就避免了射线照射到拖动装置上引起的拖动装置及推动件对扫描图像的影响,从而使得扫描图像仅含有被检车辆的透射信息。The present invention determines the first sensor 1114 by first arranging the positions of the first sensor 1114 and the second sensor 1124 and the initial position of the second elongated traction member of the second drag device on the front and rear segmented drag devices. The positional relationship between the two sensors 1124 and the second pushing member 1123, and precisely controlling the movement of the pushing members on the two-stage dragging device by the front and rear of the controller, so that the vehicle can pass through the two-stage scanning device at a constant speed without changing the radiographic inspection system. The beam outgoing frequency of the X-ray generating device does not need to consider the wheel diameter adjustment acceleration/deceleration time, which reduces the complexity of the beaming and detection system control and improves the detection efficiency of the system. In addition, the radiation inspection system disposed between the first drag device and the second drag device may emit rays from the radiation source through the gap between the first drag device and the second drag device, and be detected by the detector. Receiving, this avoids the influence of the drag device and the pusher on the scanned image caused by the irradiation of the radiation onto the drag device, so that the scanned image contains only the transmission information of the inspected vehicle.
进一步地,在第一推动件1112与车辆后轮分离前,第二推 动件1123与车辆前轮接触。Further, before the first pushing member 1112 is separated from the rear wheel of the vehicle, the second push The moving member 1123 is in contact with the front wheel of the vehicle.
进一步地,所述第二细长牵引件的初始位置根据预设的所述第二推动件与所述第二传感器之间的距离进行设置。Further, an initial position of the second elongated traction member is set according to a preset distance between the second pushing member and the second sensor.
在本发明实施例中,在第一拖动装置111的B点布置第一传感器1114检测车辆前轮离开的下降沿,车辆的从左向右由第一拖动装置111运动到第一拖动装置112,左边的第一拖动装置111的第一推动件1113推动车辆的后轮,使小车以速度V向右运动。当车辆前轮到达设置于位置B处的传感器时,右边的第二拖动装置112上的第一推动件1123停靠在初始位置C点。在第二拖动装置112的A点布置第二传感器,A点为车辆前轮行进到刚好与第二拖动装置112接触的位置。In the embodiment of the present invention, the first sensor 1114 is disposed at the point B of the first drag device 111 to detect the falling edge of the front wheel of the vehicle, and the left to right of the vehicle is moved from the first drag device 111 to the first drag. The device 112, the first pusher 1113 of the first drag device 111 on the left pushes the rear wheel of the vehicle to move the cart to the right at a speed V. When the front wheel of the vehicle reaches the sensor disposed at the position B, the first pusher 1123 on the right second drag device 112 is docked at the initial position C. A second sensor is disposed at point A of the second drag device 112, and point A is a position at which the front wheel of the vehicle travels just in contact with the second drag device 112.
其中,所述第二细长牵引件1122的初始位置根据预设的所述第二推动件1123与所述第二传感器1124之间的距离进行设置,使得直线距离BA与弧线CA相等,因此,在车辆前轮离开B时,启动第二拖动装置112,并以同样的速度V靠近车辆前轮(不考虑加速时间),第二拖动装置的第二推动件1123正好能靠住车辆前轮以速度V匀速推动车辆前进,以保持车辆的运行状态。由于B点的第一传感器1114检测车辆前轮离开时的下降沿,第二拖动装置的第二推动件1123启动时机不受被扫描车辆车轮直径变化的影响。其中,B点布置的第一传感器1114位置需要与弧长CA对应、高度需要定在推进器与车轮接触点的高度。The initial position of the second elongated traction member 1122 is set according to a preset distance between the second pushing member 1123 and the second sensor 1124, so that the linear distance BA is equal to the arc CA, When the front wheel of the vehicle leaves B, the second drag device 112 is activated and approaches the front wheel of the vehicle at the same speed V (regardless of the acceleration time), and the second pushing member 1123 of the second drag device can just lean against the vehicle. The front wheel pushes the vehicle forward at a constant speed V to maintain the running state of the vehicle. Since the first sensor 1114 at point B detects a falling edge when the front wheel of the vehicle leaves, the timing of the second pushing member 1123 of the second drag device is not affected by the change in the diameter of the wheel of the scanned vehicle. Wherein, the position of the first sensor 1114 disposed at point B needs to correspond to the arc length CA, and the height needs to be set at the height of the contact point between the propeller and the wheel.
本发明的另一实施例中,在第一拖动装置111的B点布置第一传感器1114检测车辆前轮离开的下降沿,第二细长牵引件1122的初始位置根据预设的所述第二推动件1123与所述第二传感器1124之间的距离进行设置,使得直线距离BA大于弧线CA,即BA>CA,则在车辆前轮离开B时,延迟一个时间段再启动第二细长牵引件1122的第二推动件1123,使其加速追赶前轮,然后减速靠轮,控制第二推动件1123紧贴到车辆前轮,并以速度V1匀 速前进,以保持车辆的匀速运行状态,使所延迟的时间段和第二推动件1123从开始移动到第二推动件1123与车辆前轮接触的时间间隔之和与第一传感器1114发出信号到第二传感器1124发出信号的时间间隔相等。类似地,同样适用于直线距离BA等于或小于弧线CA。其中第二推动件1123的速度-时间曲线可参照图7。In another embodiment of the present invention, the first sensor 1114 is disposed at a point B of the first drag device 111 to detect a falling edge of the front wheel of the vehicle, and the initial position of the second elongated traction member 1122 is according to the preset The distance between the second pushing member 1123 and the second sensor 1124 is set such that the straight line distance BA is greater than the arc CA, that is, BA>CA, when the front wheel of the vehicle leaves B, the second thinning is delayed for a period of time. The second pushing member 1123 of the long traction member 1122 accelerates to catch the front wheel, then decelerates the wheel, and controls the second pushing member 1123 to be in close contact with the front wheel of the vehicle, and is evenly circulated at a speed V1. Speeding forward to maintain the uniform running state of the vehicle, causing the delayed period of time and the sum of the time interval between the second pusher 1123 and the second pusher 1123 to contact the front wheel of the vehicle and the first sensor 1114 to signal The time interval at which the second sensor 1124 signals is equal. Similarly, the same applies to the straight line distance BA being equal to or smaller than the arc CA. The speed-time curve of the second pushing member 1123 can be referred to FIG.
其中,第二细长牵引件1122加速运动,然后再减速运动到第一速度。Wherein, the second elongated traction member 1122 accelerates and then decelerates to the first speed.
其中,所述加速运动可以是匀加速运动。Wherein, the acceleration motion may be a uniform acceleration motion.

In the solution of the embodiment, the vehicle moving speed is maintained at V1, and it is not necessary to change the beam outgoing frequency of the X-ray generating device in the radiographic inspection system, and the wheel diameter adjustment acceleration/deceleration time is not considered, thereby reducing the complexity of the beaming and detecting system control.
