具体实施方式
以下结合附图以及具体实施例,对本发明的技术方案进行详细描述。
图1示出了本发明实施例的辐射检查***结构示意图,其中,射线源210和阵列射线探测器220分别位于检测通道两侧,当移动目标例如车辆行驶通过时,射线源210发出扫描射线,探测器220接收到穿透移动目标之后的射线,转换为相应的数字量,经成像***(图中未示出)处理之后可形成数字辐射图像,完成射线扫描安检过程。在扫描过程中,辐射源射线经准直器准直,被限制在扫描区域内,超出扫描区域的目标物不受射线照射。关于扫描区域,是指辐射源210的出束所占据的空间区域,为防止人员意外受到辐射,可根据实际需求调整扫描区域的范围。
图1实施例中,沿扫描检测通道依次布置的检测单元110、120、130、140、150、160为距离射线源不同距离的检测单元,用于检测移动目标的到达或离开。这些检测单元可以是光电开关、光幕、地感线圈、轴重传感器等,也可以是这些传感器的组合。这些检测单元可以布置在扫描通 道的地面以上,也可以布置在扫描通道的地面以下。
其中,检测单元110和160分别位于在检测通道两端,可检测是否有移动目标例如车辆到来、是否已全部驶入检测通道、是否已驶出检测通道。如图1所示,如果车辆从左端进入通道,则左端为入口,右端为出口;反之,如果车辆从右端进入,则右端为入口,左端为出口。
其中,检测单元120和150位于扫描通道内,分别位于扫描区域的两侧,与扫描区域相距一定距离,这个距离由移动目标中需要进行辐射屏蔽的部分的长度决定。例如对于车辆,需要屏蔽的部分是司机所在的驾驶室区域,则检测单元120、150分别到扫描区域边界的距离应不小于驾驶室部分的长度。
其中,令检测单元120和150与扫描区域相距一定距离,也就是令检测单元120与扫描区域的左边界(实际上是垂直于纸面的竖直平面)相距一定距离,同时令检测单元150与扫描区域的右边界相距一定距离,具体相距1-3米为宜。检测单元120到扫描区域左边界的距离和检测单元150到扫描区域右边界的距离可以相等,也可以不等。
在本发明的某些实施例中,检测单元120或150包含若干传感器,沿通道相互间隔地布置,每个传感器均可独立地视为检测单元120或150使用,目的是对不同类型的移动目标中需要屏蔽的部分进行探测确认,以实现避让。举例来讲,对于各类车辆的辐射检测,需对驾驶员所在的驾驶室实行避让,布置的多个传感器相隔一定距离,不仅能够对体积较大的卡车、车辆类驾驶室进行探测,也能够对体积较小的轿车类驾驶室进行探测,从而对驾驶室、驾驶员的100%辐射避让。
在本发明的某些实施例中,检测单元130和140分别位于扫描区域两侧,在临近扫描区域的位置,例如检测单元130到扫描区域左边界的距离为0.1-1m,检测单元140到扫描区域右边界的距离为0.1-1m,两个距离可以相等也可以不等。检测单元130和140可检测移动目标是否离开扫描区域,通知控制***立即停止射线源出束,减少不必要的射线照射。
在本发明的某些实施例中,在检测单元110和160所在位置附近, 可以布置挡杆和交通信号灯(图1中未示出),控制移动目标的行驶,防止无关的移动对象意外进入扫描通道。
图2示出了本发明实施例对移动目标进行辐射检查的方法流程图,参考图1,检查时,车辆可以从通道左侧进入,也可以从右侧进入。当自动检查***处于就绪状态时,位于检测单元110和160所在位置的挡杆为打开状态,交通灯为绿灯。以车辆从左侧进入扫描通道为例,首先到达检测单元110,将检测单元110触发,则检测单元110和160所在位置的交通灯变为红灯;当检测单元110检测到车辆已完全驶入检测通道,检测单元110所在位置的挡杆放下,防止后续车辆的意外进入;然后车辆依次到达检测单元120,130,140(此时辐射源不发出射线),当车辆到达150时,表明车辆需要避让的驾驶室部分已经通过了扫描区域,而车辆需要被检查的车厢部分已进入了扫描区域;此时,控制***接收到150被触发的信号后,控制射线源发出射线,对车辆的车厢进行扫描检查;在此过程中车辆继续前行,当车辆尾部离开扫描区域时,检测单元140检测到车辆离开其位置;控制***接收到140的信号后,立即控制射线源停止发出射线,减少不必要的射线照射;然后车辆依次离开150,160;当检测单元160检测到车辆离开后,控制***根据160的信号,将检查***切换到就绪状态,令通道两端的交通信号灯变为绿灯,两端的挡杆全部打开。
在移动目标辐射扫描过程中,如果目标行驶速度过慢,不宜开启辐射扫描。为此,在本发明的自动检查过程中,还可设置车速检测机制,参照图3,仍以车辆从左侧进入检测通道为例,在检测单元110被车辆触发之后,控制***还记录车辆到达检测单元140和150的时刻。检测单元140和150的距离是已知的,根据这个距离和车辆到达检测单元140和150的时间差,如此可以计算出车辆的车厢(已除去驾驶室部分)经过扫描区域时的速度。当控制***检测到移动目标的速度时,根据这个速度判断是否控制射线源发射射线对移动目标进行扫描。如果移动目标的速度过小,例如小于3km/h,对人员的辐射变得很难避免,此时不应实施辐射扫描,应结束流程,选择其它方式完成安检。反之,如果移动目 标的速度足够大,例如不小于3km/h,则可以打开射线源进行扫描检查。在不同的应用场景中,可按照实际需求设定适合开启辐射扫描的车辆速度阈值。
在本发明的某些实施例中,成像***还可以根据控制***检测到的车辆速度,对获得的扫描图像进行车辆行进方向上的图像校正,减少因车辆速度变化引起的图像变形。
以下描述车辆从图1的右侧进入扫描通道的情形。160检测到车辆到达,检测单元110和160所在位置的交通灯变为红灯;当160检测到车辆离开,160所在位置的挡杆放下,防止后续车辆的意外进入;车辆依次到达检测单元150,140,130,当车辆到达120时,表明车辆需要避让的车头已经通过扫描区域,而车辆需要被检查的车厢进入扫描区域;控制***接收到120的信号后,根据车辆到达检测单元120和130的时刻计算出行进的速度,如果速度符合要求,控制射线源发出射线,对车辆的车厢进行扫描检查;车辆继续前行,当车辆离开扫描区域时,检测单元130检测到车辆离开其位置;控制***接受到130的信号后,控制射线源停止发出射线,减少不必要的射线照射;车辆依次离开检测单元120,110;当110检测到车辆离开后,控制***根据110的信号,将检查***切换到就绪状态,通道两端的交通信号灯变为绿灯,两端的挡杆全部打开。
图4为本发明实施例的辐射检查工作状态转移图,可以看到,辐射检查***处于就绪状态后,只有按特定的顺序依次触发相应的传感器,并且目标移动速度满足要求时,射线源才会被打开,保证***可以正确避让需要避让的部分,并对需要检查的部分启动扫描检查。
图5为本发明实施例的辐射检查***结构图,图5实施例与图1实施例的区别在于,图5实施例中省略了图1实施例中使用的检测单元130和140,作为替代,原来由检测单元130执行的检测由检测单元120来执行,原来由检测单元140执行的检测由检测单元150来执行,为控制***提供扫描检测流程中所需的信号。图6示出了图5实施例的辐射检查***执行扫描任务时的流程图。
在本发明的某些实施例中,为应对地面交通路网复杂的情况,可将 自动检查***与地面交通有多条不同方向的道路相连接,图7所示为检测通道两端各有两条道路的情况。与图1实施例相比较,图7实施例将往来车辆进行了划分,使车辆在驶入和驶出时不再共用入口和出口,而是通过专门的入口进入检测通道,再通过专门的出口驶离,有利于对双方向车辆检测的调度控制。同理,对于图5实施例的检测***,可按照图8所示的道路连接方式布置。
对于图7和图8实施例,由于入口和出口的增多,相应地,入口和出口处的检测单元也有所增加,以检测单元111和112代替原来的检测单元110,以检测单元161和162代替原来的检测单元160,其余检测单元的设置不变。另外,在设置挡杆和交通灯时,可在所有入口和出口处设置,也可仅在作为入口的检测单元112和161处布置挡杆和交通灯。
在本发明的某些实施例中,控制***可以设定相邻检测单元被顺序触发的最长时间差,例如设定为15s,如果两相邻检测单元被触发的时间间隔超过这一设定值,则控制***停止检查流程,重新将检查***切换至就绪状态,防止因检测单元被意外触发,或因其他故障发生,而导致检查***长时间处于激活状态。
在图7和图8实施例中,无论车辆从哪个方向驶来均可对其实施辐射检查,例如在一个方向上,移动目标从112驶入、162驶出,在另外一个方向,移动目标从161驶入、111驶出,检查***整体布置紧凑,占地面积小。
辐射检查时,当自动检查***处于就绪状态时,位于检测单元112、161所在位置的挡杆打开,位于检测单元112、161所在位置的交通灯为绿灯。当112检测到车辆到达,112、161所在位置的交通灯变为红灯,161所在位置的挡杆放下;当112检测到车辆离开,112所在位置的挡杆放下,防止后续车辆的意外进入;车辆依次到达120,130,140,当车辆到达150时,表明车辆需要避让的车头已经通过扫描区域,而车辆需要被检查的车厢进入扫描区域;在车辆行驶速度大于预定值的前提下,立即控制射线源发出射线,对车辆的车厢进行扫描检查;车辆继续前行,当车辆离开扫描区域时,140检测到车辆离开其位置;控制***接受到 140的信号后,立即控制射线源停止发出射线,减少不必要的射线照射;车辆依次离开150,162;当162检测到车辆离开后,控制***根据162的信号,将检查***切换到就绪状态,通道两端的交通信号灯变为绿灯,两端的挡杆全部打开。
同理,当检测单元161检测到车辆到达,检测单元112、161所在位置的交通灯变为红灯,112所在位置的挡杆放下;当161检测到车辆离开,161所在位置的挡杆放下,防止后续车辆的意外进入;车辆依次到达150,140,130,当车辆到达120时,表明车辆需要避让的车头已经通过扫描区域,而车辆需要被检查的车厢进入扫描区域;在车辆行驶速度大于预定值的前提下,立即控制射线源发出射线,对车辆的车厢进行扫描检查;车辆继续前行,当车辆离开扫描区域时,130检测到车辆离开其位置;控制***接受到130的信号后,立即控制射线源停止发出射线,减少不必要的射线照射;车辆依次离开120,111;当111检测到车辆离开后,控制***根据111的信号,将检查***切换到就绪状态,通道两端的交通信号灯变为绿灯,两端的挡杆全部打开。
在本发明的某些实施例中,自动检查***在就绪状态时,所有挡杆放下。只有当检测单元110、112、160、161检测到移动目标到达时,与移动目标行进方向相对应的挡杆才打开。
在本发明的某些实施例中,辐射检查时,当自动检查***处于就绪状态时,位于检测单元112、161所在位置的挡杆放下,位于检测单元112、161所在位置的交通灯为红灯。在检测单元112、161检测到有移动目标到达时,控制***或操作人员根据两个方向的交通流量情况,选择打开其中一个行进方向的挡杆,允许该行进方向移动目标进入进行扫描检查。在该行进方向移动目标离开检查***之后,控制***或操作人员根据两个方向的交通流量情况,确定选择打开其中一个行进方向的挡杆,让下一移动目标进入检测通道进行扫描检查。
在本发明的某些实施例中,可为检查***设置优先检查机制,当检查***处于就绪状态时,使一个行进方向的通道挡杆保持打开(交通灯为绿灯),而另一个行进方向的通道挡杆保持关闭(交通灯为红灯),则 当双方向同时有车辆待检查时,档杆为打开的一侧的车辆可优先进入检测通道进行扫描检查。举例来讲,将图5中从左向右的方向选定为优先检查方向,则当***就绪时,位于检测单元112所在位置的挡杆是打开的,而位于检测单元161所在位置的挡杆处于关闭状态,同时位于检测单元112所在位置的交通灯为绿灯,161所在位置的交通灯为红灯。当双方向都有车辆靠近时,检测单元112一侧的车辆可以直接驶入检测通道,而检测单元161一侧的车辆无法驶入。车辆由检测单元112一侧进入扫描通道时,该处交通灯变为红灯,当离开检测单元112所在位置后,该处挡杆放下,在完成扫描检查离开检测单元162所在位置后,***恢复为之前的就绪状态。之后,检测单元161检测到有车辆到达,打开161处挡杆,交通灯变为绿灯,同时,112处挡杆关闭,交通灯变为红灯,车辆从检测单元161一侧进入。另外,按照相似的流程,可将从右向左的方向设置为优先检查的驶入方向。
本发明实施例对多个检测单元进行合理布置,对移动目标检查过程中的辐射控制流程进行了相应设计,利用本发明的实施例可对地面交通***中来自不同方向的移动目标进行扫描检查,安检效率高,检查过程中能够有效地避让需要屏蔽的部分,对于行进速度较慢的目标不予辐射扫描,确保人员安全。
以上,结合具体实施例对本发明的技术方案进行了详细介绍,所描述的具体实施例用于帮助理解本发明的思想。本领域技术人员在本发明具体实施例的基础上做出的推导和变型也属于本发明保护范围之内。
