发明人经过研究发现,相关技术中检测装置在实际应用时的避让效果并不是很好,经常出现漏检问题;而且,检查装置只能针对驾驶室在前、货物在后的情况进行避让,对于驾驶室在后、货物在前的情况以及机车与客车、货车混编的情况,则不能做到很好的避让。
如图1~图5所示,在本公开提供的安全扫描检查系统的一个实施例中,该安全扫描检查系统包括检测装置、扫描装置1和控制装置,其中,检测装置用于检测被检物2、2′的防护属性,扫描装置1可动地设置,扫描装置1用于在运动的过程中发射扫描射线以对被检物2、2′进行安全扫描检查,扫描装置1具有至少两个工作模式,每个工作模式对应的扫描射线的剂量与其他工作模式对应的扫描射线的剂量不同,控制装置用于根据检测装置所检测的被检物2、2′的防护属性调节扫描装置1的工作模式。
在上述实施例中,通过设置检测装置,可以对被检物的防护属性进行检测,从而使得控制装置可以根据被检物的防护属性调节扫描装置的工作模式,实现针对不同的防护属性采用不同的工作模式的效果,对需要避让的被检物可以实现有效避让,对需要检测的被检物也可以及时准确地检测,避免漏检;能够适应驾驶室在前或驾驶室在后的情况,也能够适应机车、客车和货车混编的情况,提高了对被检物的适应能力,扩大了安全扫描检查系统的适用范围。
而且,在上述实施例中,扫描装置1可动地设置,即扫描装置1是可运动的,这样在安全扫描检查时,可以使被检物不动,而扫描装置1相对于被检物运动;或者,被检物也动,且扫描装置1与被检物的运动速度不同。相比于扫描装置不动而被检物移动的方案来说,本公开实施例可以避免由于被检物的运动误差或者故障等原因造成堵塞安全扫描检查通道、降低安全扫描检查效果以及造成检查检查的失败等问题,有效保证安全扫描检查的可靠性,提高安全扫描检查效率。
在一些实施例中,检测装置用于检测具有至少两个不同防护属性的分段的被检物2、2′,控制装置在检测装置检测到被检物2、2′的防护属性变化时实时切换扫描装置1的工作模式。这样设置的好处是,可以更加精准地实现对具有不同防护属性的被检物的针对性检查,有效保护需要避让的被测物,同时防止漏检,提高安全扫描检查的安全性,也有利于提高安全扫描检查效率。
在一些实施例中,扫描装置1包括第一工作模式、第二工作模式和第三工作模式, 在第一工作模式下扫描装置1的射线剂量大于在第二工作模式下扫描装置1的射线剂量,在第三工作模式下扫描装置1的射线剂量为零。
如图1所示,被检物2包括车头段22和车身段21,控制装置先检测车身段21再检测车头段22,在检测到车身段21时调节扫描装置1的工作模式为第一工作模式,且在检测到车头段22时调节扫描装置1的工作模式为第二工作模式或第三工作模式。这样对于倒着进入扫描通道的被检物,也可以实现顺利检测。
如图2所示,被检物2′包括机车段21′、客车段22′和货车段23′,控制装置用于按照机车段21′-客车段22′-货车段23′的顺序进行检测,并在检测到机车段21′时调节扫描装置1的工作模式为第二工作模式或第三工作模式,在检测到货车段23′时调节扫描装置1的工作模式为第一工作模式,且在检测到客车段22′时调节扫描装置1的工作模式为第二工作模式或第三工作模式。这样对于混编的列车组也可以实现顺利检测。
如图3所示,被检物2′包括机车段21′、客车段22′和货车段23′,控制装置用于按照货车段23′-客车段22′-机车段21′的顺序进行检测,并在检测到客车段22′时调节扫描装置1的工作模式为第二工作模式或第三工作模式,在检测到货车段23′时调节扫描装置1的工作模式为第一工作模式,且在检测到机车段21′时调节扫描装置1的工作模式为第二工作模式或第三工作模式。
当然,除了图2和图3所示的混编情况,在其他实施例中,混编的列车组可能是如图4和图5所示的情况,对于这些混编情况,通过检测装置对每个车段进行检测,控制装置根据每个车段的防护属性调节至相应的工作模式,实现有效避让,还可以避免漏检。
本公开安全扫描检查系统实施例可适应的被检物2除了车头和车身的区别,机车与客车、货车的区别,还有可能是车辆类型的不同,比如工程车辆或特殊车辆等,也可以根据其防护属性,调节不同的工作模式。
而且,工作模式也不仅限于上述的三种,还可以有射线剂量为其他数值的工作模式。
在一些实施例中,检测装置包括车型识别装置,车型识别装置用于识别的被检物2、2′的车型,并根据车型确定被检物2、2′的防护属性。根据车型判断被检物的防护属性,是一种比较准确和可靠的判断方式,有效保护需要避让的被检物。
在一些实施例中,车型识别装置包括轴距测量装置和车型确认装置,轴距测量装 置用于测量被检物2、2′的轴距,车型确认装置用于根据轴距测量装置所测量的轴距确定被检物2、2′的车型。
在一些实施例中,车型识别装置包括图像拍摄装置和车型确认装置,图像拍摄装置用于拍摄被检物2、2′的图像,车型确认装置用于根据图像拍摄装置所拍摄的图像确定被检物2、2′的车型。
在一些实施例中,车型识别装置包括激光扫描仪和车型确认装置,激光扫描仪用于扫描被检物2、2′并获得被检物2、2′的三维图像,车型确认装置用于根据激光扫描仪所扫描的三维图像确定被检物2、2′的车型。
当然,除了以上三种方式外,在其他实施例中,也可以采用那其他可行的方式来确定被检物的车型。
通过对本公开安全扫描检查系统的多个实施例的说明,可以看到本公开安全扫描检查系统实施例至少具有以下一种或多种优点:
