Description

驻波电子直线加速器及集装箱 /车辆检查系统 技术领域
本发明涉及一种驻波电子直线加速器、 及使用了该驻波电子直线 加速器的集装箱 /车辆检查系统, 特别地, 涉及双通道快速式集装箱 / 车辆检查系统、 车载移动式集装箱 /车辆检查系统、 以及组合移动式集 装箱 /车辆检查系统。
背景技术
以往, 在集装箱 /车辆检查系统中, 广泛地使用辐射成像技术。 其中, 作为辐射成像技术中的辐射源, 有采用低能驻波电子直线 加速器 (以下有时简称为加速器) 的技术。 低能驻波电子直线加速器 主要包括: 控制机构、 调制器、 磁控管、 微波传送系统、 射线机头组 件等。
其工作原理为, 控制机构进行控制而使得由调制器产生高压脉沖 , 将该高压脉沖通过脉沖变压器提供给磁控管, 从而在磁控管中产生射 频微波。 将该射频微波通过微波传送系统馈入到射线机头组件的加速 管中, 在加速管中形成正向波与反向波, 二者叠加而形成驻波。
另外, 调制器内的电子枪电源产生高压脉沖并向加速管的电子枪 提供该高压脉沖。 利用该高压脉沖, 将电子从电子枪的由灯丝加热的 阴极上拉出来, 并将其加速发射至加速管的加速腔中。 电子与加速腔 中的轴向驻波电场相互作用, 并从中吸收能量, 不断被加速。 当电子 加速终了时, 打到靶上而产生一连续谱 X射线。 利用屏蔽设备及外准 £器将其他角度方向的 X射线很好地屏蔽, 只在前向留下一个所需形 状的 X射线束。
图 1是表示现有技术的驻波电子直线加速器的微波传送系统的示 意图。 如该图所示, 该微波传送系统连接在磁控管和加速管之间而用 于把磁控管产生的微波传递给加速管, 主要包括弯波导管、 四端环流 器、 直波导管、 软波导管、 和波导窗等。
根据该图 1可知, 在现有技术的情况下, 来自磁控管的微波经由 一个微波^送系统被供给至一个加速管, 对该一个加速管内的电子进 行加速。然后被加速后的电子对一个靶进行打靶而形成连续谱 X射线。 即, 现有技术为单靶式驻波电子直线加速器。 但是, 根据上述现有技术, 利用一个上述驻波电子直线加速器仅 能对单个靶进行打靶而产生一个 X射线束。
关于集装箱 /车辆检查系统, 根据现有技术, 检测系统为一种单通 道式检查系统, 辐射源为单靶式驻波电子直线加速器, 所以其在检测 时只能够向一个扫描通道发射连续谱的 X射线, 无法同时对两个集装 箱 Z车辆进行辐射成像检查。 从而导致检查效率降低。
关于车载移动式集装箱 /车辆检查系统, 专利文件 1公开了一种车 载移动式集装箱检查系统。 其在扫描车上安装可以相对扫描车运动的 回转平台, 在回转平台上安装以四连杆机构铰接组成的平行四边形支 ; ° 架及与该支架连接的带探测器的横探测器臂架和竖探测器臂架。 并且, 安装有辐射源的箱形舱安装在回转平台的尾端。 在进行检查时, 扫描 车上的回转平台旋转 90度, 由平行四边形支架、 横探测器臂架、 竖探 测器臂架形成龙门架而构成扫描通道。 并且, 通过控制机构使辐射源 放出 X射线, 该 X射线所形成的扇面穿过被检集装箱, 由横探测器臂
: 架和竖探测器臂架中探测器接收后, 转换成电信号而输入图像获取模 块, 图像获取模块将图像信号输送给图像分析软件处理, 并由计算机 显示检测到的结杲。
根据专利文件〗 的车载移动式集装箱检查系统, 也为一种单通道 式检查系统, 无法同时对两个集装箱进行辐射成像检查。 从而, 导致 0 检查效率降低。
关于可组合移动的集装箱检测系统, 图 16为专利文件 2公开的一 种可组合移动的集装箱检测系统, 其包括活动屏蔽间, 自动扫描车和 远程控制机构。 其中, 活动屏蔽间是可拆卸拼装的, 在自动扫描车上 装有由带探测器的水平臂和垂直臂组成的门框架、 辐射源及可双向移
?- 动的拖车架, 根据该专利文件 1的发明, 由于屏蔽间能够拆卸拼装且 自动扫描车能够行驶, 所以能够实现检测系统的异地随机检测、 且不 占用固定的检测空间, 能够节省固定检测场地的投资。
但是, 根据上迷现有技术, 检测系统也为一种单通道式检查系统, 无法同时对两个集装箱进行辐射成像检查。 从而导致检查效率降低。 G 专利文件 CN 1490616A。

首先, 应该指出的是, 本节描述的仅仅是用于实施本发明的优选 实施方式, 在不改变本发明的原理的前提下, 本领域技术人员能够对 0 这里描述的技术方案做出改型和 /或变型, 这些改型和 /或变型也将落入 本发明的范围内。
以下参照附图详细说明本发明的具体实施方式。
(一) 低能驻波电子直线加速器
1、 具体例 1
' 图 2是本发明的驻波电子直线加速器 ( 107、 207、 307 ) 的示意框 图, 图 3是本发明的驻波电子直线加速器的一例的俯视图, 图 4是本 发明的驻波电子直线加速器的一例的主视图。 图 4中的左右方向、 图 3 中的上下方向是驻波电子直线加速器的左右方向, 在将驻波电子直线 加速器向集装箱 /车辆检查系统安装时, 令集装箱 /车辆检查系统的左右 0 方向与驻波电子直线加速器的左右方向一致。 图 3中的左右方向、 图 4 中的垂直纸面方向为驻波电子直线加速器的前后方向, 在将驻波电子 直线加速器向集装箱 /车辆检查系统安装时, 与集装箱 /车辆的行进方向 一致。
如从图 2至图 4所示可知, 本发明的双靶式的驻波电子直线加速 器 107能够利用一个微波传送系统将由一个磁控管 17产生的射频微波 同时馈入一对的加速管 (第一加速管 13及第二加速管 18) , 在该一对 的加速管 13、 18中分别形成加速微波场, 为各加速管 13、 18提供加 速所需的能量。
在图 3、' 图 4中例示的实施例中, 两个加速管 13、 18在主视方向 (图 3的左右方向、 图 4的垂直纸面方向) 中位置错开且分别相对于 水平方向倾斜布置。 且两加速管 13、 18分别发射的 X射线束的扇面沿 着驻波电子直线加速器 107的左右方向。
具体而言, 驻波电子直线加速器 107具有用来产生高压脉沖的省 略图示的调制器, 该调制器产生的高压脉沖通过脉沖变压器 14被变换 为适宜的脉沖后被供给至作为微波源的磁控管 17。该磁控管 17接收到 上述高压脉冲后输出脉沖形式的射频微波, 该射频微波通过微波传送 系统而被分别传递至一对的加速管 〗3、 18中, 在各加速管 13、 18的 内部形成驻波而用于令各加速管 13、 18中的电子加速。
微波传送系统主要可以包括用于传递微波功率的波导管 16、 作为 隔离器的环流器】5、 用于隔离加速管和微波传送系统的波导窗 25等。
其中, 波导管 16能够根据实际的结构、 布置需要等而适宜地使用 直波导管、 弯波导管、 软波导管等, 或者也可以将这些适宜地进行组 合来使用。在图 2所示的实施例中,作为波导管 16是组合了弯波导管、 直波导管、 软波导管而进行使用的。
此外, 作为环流器 15, 本发明中使用四端环流器, 图 7是示意地 表示四端环流器的结构框图。 参照图 2、 图 7, 四端环流器 15作为隔 离器使用, 来自上游的波导管 16的微波功率被从其第一端口输入并从 第二端口输出,经由下游侧的波导管 16而被送往一对的加速管 13、 18。 从 -对的加速管 13、 18反射回来的微波功率从第二端口进入并由第三 端口输出, 被连接在第三端口的大负载吸收。 从大负载反射的少量微 波功率再被送到第四端口而被连接在第四端口的小负载吸收。 从第二 端口到第一端口间的隔离度很高, 一般大于 25dB, 从而, 由各加速管 13、 18反射的功率经过四端环流器 15后只有极小部分回到磁控管 17, 因此磁控管 17的工作状态受作为其负载的各加速管 13、 18的影响很 小。 四端环流器 15需要恒温冷却水来保证其工作时温度基本稳定, 过 大的温度变化会影响其插入损耗、 隔离度等参数, 进而影响磁控管 Π 的正常工作及注入各加速管 13、 18的微波功率。 需要说明的是, 这里 作为环流器 15例举了四端环流器, 但并不限定于此, 例如也可以采用 三端环流器等。
特别地, 在本发明的微波传送系统中还具有用于令微波向各加速 管 13、 18分支的微波分配器 21。 该微波分配器设置在微波传送系统的 末端附近。 在图 2所示的实施例中, 微波分配器 21的两个输出口分别 经由波导管 16及波导窗 25与第一加速管 13及第二加速管 18连接, 用于将来自上游侧的微波向下游的各加速管 13、 18分支。
图 8是表示本发明的微波分配器的一例的示意图。 如该图所示, 该微波分配器 21是具有一个输入口和两个输出口的分支管。 但是, 本 发.明的微波分配器 21 并不限定于上述结构, 只要能够令微波传送系统 向两个加速管 13、 18分支, 也可以为其他任意结构。 例如微波分配器 可以根据需要而采用各种公知的材质和形式。
接着, 微波传送系统的微波从各微波分配器 21分支而经由下游的 波导管 16及波导窗 25被传递至各加速管 13、 18。 此时, 能够通过调 节馈入各加速管的微波的相位而在各加速管 13、 18中形成正向波和反 向波, 该正向波和反向波叠加从而能够在各加速管 13、 18中分别形成 稳定的驻波加速电场。
此外, 在第一加速管 13的入口附近设置有用于对第一加速管 13 内抽真空的钛泵 24、和用于向第一加速管 13 内发射电子束的第一加速 管用电子枪 23,在第二加速管 18的入口附近设置有用于对第二加速管 18内抽真空的钛泵 24、 和用于向第二加速管 18内发射电子束的第二 加速管用电子枪 22。 调制器经由省略图示的电子枪前置变压器对该两 个电子枪 22、 23供给高压脉沖。
在这些电子枪 22、 23的各自中, 高压脉沖将电子从由灯丝加热后 的阴极上拉出而形成电子束, 并将其分别加速发射到各加速管 13、 18 中
该被发射到各加速管 13、 18中的电子束在稳定的驻波加速电场中 吸收能量而被加速。
如图 4所示, 在第一加速管 13的末端侧内设置有第一加速管用靶 1 9 , 在第二加速管 1 8的末端侧内设置有第二加速管用靶 20。 在各加速 管 1 3、 1 8中被加速的电子束分别轰击各靶 1 9、 20而能够分别产生一 连续谱 X射线。 此时, 两个靶产生的 X射线束的计量可以相同也可以 不同。 在各加速管 1 3、 1 8的出口处, 对应于上述 X射线而在适当的位 置分别设置屏蔽设备 1 1,各屏蔽设备 1 1仅在需要的方向保留所需形状 的 X射线束并屏蔽其他角度的 X射线。 此时, 两个加速管 13、 1 8都 能够产生单能量或者双能量的 X射线。
从而, 根据本发明, 能够利用一个驻波电子直线加速器 107同时 向左右两方发射 X射线束。
另外, 在本实施例中, 下述集装箱 /车辆检查系统中的辐射源控制 模块可以通过分别控制第一加速管用电子枪 23和第二加速管用电子枪 22的电子束的发射而控制辐射源 107向两侧发射的 X射线束的通断。

在图 10中例示了第一门组件及第二门组件沿集装箱卡车 104的行 进方向相互错开的结构。 此时, 作为辐射源采用上述具体例 1 的双靶 式直线加速器, 其两个加速管 1 3、 1 8在主视方向 (图 3的左右方向、 0 图 4的垂直纸面方向) 中位置错开地布置。 从而在将该驻波电子直线 加速器 1 07布置在设备舱 1 06中时, 分别向第一扫描通道 1 05和第二 扫描通道 125发射的 X射线束的射入位置在集装箱卡车 1 04的行进方 向中相互错开。 由此, 向第一、 第二扫描通道 105、 125中分别发射的 X射线束的扇形面分别垂直于集装箱卡车 104的行进方向且而在集装 箱卡车 1 04的行进方向中相互错开, 从而能够更好地实现辐射防护效 果的最优化。
本发明并不一定限定于此, 在向第一、 第二扫描通道 105、 125中 分别发射的 X射线束的射入位置在集装箱卡车 104的行进方向中一致 时 (例如采用具体例 2的低能驻波电子直线加速器) , 分别向第一扫 0 描通道 1 05和第二扫描通道 1 25发射的 X射线束的扇面共面。 第一门 组件及第二门组件在集装箱卡车 104的行进方向中对齐。

在第一扫描通道 105中设置第一速度传感器 1 17、在第二扫描通道
1 1 25中设置第二速度传感器 1 27 ,分别检测上述第一、第二扫描通道 105、 1 25中的被检测集装箱卡车 1 04的行进速度,上述辐射源控制模块基于 来自上述第一、 第二速度传感器 1 17、 127的检测结果分别控制上述辐 射源 1 07向上述第一、 第二扫描通道 105、 125发射 X射线束的出束频 率。
: ' 由此, 能够根据第一、 第二扫描通道 105、 1 25各自中的集装箱卡 车 1 04的移动速度来控制辐射源 107向第一、 第二扫描通道 1 05、 125 ^自的出束频率, 从而能够对应于不同移动速度的集装箱卡车 104进 行更为精确的检查。 特别地, 由于辐射源控制模块基于来自第一、 第 二速度传感器 1 17、 1 27的检测结果分别地控制辐射源 107向第一、 第 二扫描通道- 105、 125发射 X射线束的出束频率, 所以即便第一扫描通 道 1 05和第二扫描通道 125中的集装箱卡车 104的移动速度不一致, 也能够分别调整第一扫描通道 105和第二扫描通道 125中的 X射线束 的出束频率而对两个扫描通道 105、 125中的集装箱卡车 104都进行精 确 4 测。
30 在本实施例中,辐射源控制模块能够分别控制辐射源 107的两个 X 射线束的发射 /停止。 此外, 在第一扫描通道 105中设置第一位置传感 器 1 1 8 , 在第二扫描通道 1 25中设置第二位置传感器 128 , 在基于第一 位置传感器 1 1 8的检测结果判定集装箱卡车〗04到达第一扫描通道 105 中的既定位置时, 开始从上述辐射源 107向上述第一扫描通道 105发 射 X射线束, 在基于第一位置传感器 1 1 8的检测结果判定集装箱卡车 1 04完全通过了第一扫描通道 105时,停止从上述辐射源 107向上述第 一扫描通道 105发射 X射线束。 另一方面,在基于第二位置传感器 128 的检测结果判定集装箱卡车 104到达第二扫描通道 125中的既定位置 时, 开始从上述辐射源 107向上述第二扫描通道 125发射 X射线束, 在基于第二位置传感器 128的检测结果判定集装箱卡车 104完全通过 了第二扫描通道 125时, 停止从上述辐射源 107向上述第二扫描通道 ! 25发射 X射线束。
由此,能够在扫描通道中不存在集装箱 /车辆时停止 X射线的发射, 从而能够避免不必要的能源浪费并实现辐射安全保证。 并且, 能够根 据实际需要选择是使用单通道方式进行扫描检查还是使用双通道方式 进行扫描检查。 并且, 由于只有在判定集装箱卡车 104到达第一、 第 二扫描通道 105、 125中的既定位置时才开始发射 X射线束, 因而通过 例如将集装箱卡车 104的驾驶员到达防护位置时的位置设定为上述既 定位置, 能够在驾驶员到达防护位置后才开始向扫描通道发射 X射线, 由此能够避免驾驶员等受到 X射线的伤害。
另外, 在本实施例中, 上述辐射源控制模块基于自动控制程序自 动控制辐射源 107的动作, 从而能够节省集装箱卡车 104检查所需要 的人力。
3、 双通道式快速集装箱 /车辆检查系统的工作过程。
以下参照图 9、 图 1 0说明本发明的双通道式快速集装箱 /车辆检查 系统的工作过程, 其扫描检查过程中的控制动作自动地进行。
由于第一扫描通道 1 05、第二扫面通道 1 25中的检测动作相互对应, 仅详细说明第一扫描通道 1 05中的工作过程。
首先, 在集装箱卡车 104进入第一扫描通道 105前, 由第一速度 传感器 1 1 7及第一位置传感器 1 1 8的检测结果判断出第一扫面通道 105 中不存在集装箱卡车 1 04 , 从而控制辐射源控制模块, 从辐射源 107向 第一扫描通道 105的 X射线束的发射被切断。
当驾驶员驾驶集装箱卡车 104进入第一扫描通道 105后, 由第一 速度传感器〗1 7检测集装箱卡车 104的行进速度, 基于其检测结果,
- Y7 - 确定辐射源 1 07向第一扫描通道 105的出束频率。 同时, 由第一位置 传感器〗1 8检测集装箱卡车 1 04的位置, 当基于该第一位置传感器 1 1 8 的检测结果判定集装箱卡车 1 04的驾驶员到达预先设定的防护位置且 集装箱卡车 104所处的逻辑状态正确无误时, 辐射源控制模块控制辐 射源 107开始以上述算出的出束频率向第一扫描通道 105发射 X射线 束, 对集装箱卡车 104进行扫描检查, 利用安装于第一门框部件上的 多个第一探测器模块 101接收上述 X射线束。 将探测到的上述 X射线 束经由未图示的信号转换模块转换为电信号并输入到位于设备舱 106 内的图像获取模块从而获取检测图像。
当集装箱卡车 104继续行进而完全通过了第一扫描通道 105后, 由第一位置传感器 1 1 8及第一速度传感器 1 1 7检测到这一情况, 辐射 源控制模块控制辐射源 1 07停止向第一扫描通道 105发射 X射线束。 从而完成第一扫描通道 1 05中的一辆集装箱卡车 1 04的扫描检查。
在本实施例中, 能够分别根据进入第一扫描通道 105及第二扫描 通道 1 25中的集装箱卡车 1 04的时序来自动地开始 /停止辐射源 1 07分 别向两扫描通道的 X射线的发射, 且能够自动地根据两扫描通道 1 05、 1 25各自中的集装箱卡车 1 04的移动速度而分别调节向两扫描通道
1 05、 】25的 X射线束的出束频率, 从而能够更高效、 更精确地对两扫 描通道 105、 125各自中的集装箱卡车 104进行扫描检查。 并且, 根据 本实施例,检查系统能够对进入第一扫描通道 105及第二扫描通道 125 的任意一个中的集装箱卡车 104进行扫描检查, 也能够同时对进入上 述两个扫描通道 105、 125中的集装箱卡车 104进行扫描检查。

" 先, 一对的门组件即第一 ^探测器臂架 202与第一横探测器臂 架 203、及第二竖探测器臂架 222与第二横探测器臂架 223在升降用液 压缸 2 Η 的作用下一体地垂直上升, 在到达既定高度后停止。
然后, 旋转平台液压马达 212动作而令左右一对的旋转平台 210 与位于其上的门组件一起向左右两方旋转 90后停止。
然后, 令两个门组件中各自省略图示的展开用液压缸动作, 令各 竖探测器臂架 202、 222相对于各横探测器臂架 203、 223向下旋转 90 度而变为展开的状态。 从而, 利用两个门组件在底盘车 208的左右两侧分别形成了第一 扫描通道 205和第二扫描通道 225。
在两个扫描通道 205、 225形成后, 通过未图示的辐射源控制模块 控制作为辐射源 207的上述驻波电子直线加速器, 使其分别向底盘车 208的左右两侧发射 X射线束。
由于辐射源配置在旋转平台 210的下后方而使辐射源的 X射线源 点低于底盘车 208的底盘, 所以从辐射源放出的左右两侧的 X射线所 形成的扇面分别低位穿过第一扫描通道 205中的第一集装箱卡车 204、 及第二扫描通道 225中的第二集装箱卡车 224 , 并且位于比底盘车 208 的尾部更靠后方。
此时, 利用设置在一对的门组件的各竖探测器臂架 202、 222和各 横探测器臂架 203、 223上的多个探测器模块 201接收上述 X射线。 将 探测到的上述 X射线经由未图示的信号转换模块而转换为电信号并输 入到位于控制舱 209内的图像获取模块, 图像获取模块将图像信号输 送到运行检查模块并由显示模块显示检测结果。
在检查结束而需要令车载移动式集装箱 /车辆检查系统变为运输状 态时, 通过辐射源控制模块停止作为辐射源 207的上述驻波电子直线 加速器的工作。
然后, 控制省略图示的展开用液压缸的动作令各竖探测器臂架
202、 222相对于各横探测器臂架 203、 223旋转收回而变为水平地层叠 在各横探测器臂架 203、 223下方的状态。

203、 223都以水平状态上下层叠地保持在底盘车 208的左右方向的内 侧。
然后, 令升降用液压缸 21 1动作而令一对的门组件下降, 从而成 为将一对的门组件的各竖探测器臂架 202、 222和各横探测器臂架 203、 223以水平状态上下层叠地保持在控制舱的上方的收起状态。
在上述实施方式中, 公开了一对的门组件分别由能够折叠横探测 器臂架及竖探测器臂架构成、 且其借助左右一对的旋转平台、 升降用 是并不一定限定于此, 例如构成各门组件的部件的形态、 个数、 动作 方式能够根据实际需要适宜地变更。 例如也可以省略旋转平台而分别 借助旋转致动器直接驱动一对的门组件旋转。
