Description

探测器的保护***、方法及计算机可读介质
本申请要求在2022年11月29日提交中国专利局、申请号为202211520579.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及信息技术领域，尤其涉及一种探测器的保护***、方法及计算机可读介质。
背景技术
流气正比计数管即本文中的“探测器”，其实际上是一个换能器。用在X射线方面，就是将辐射的X射线光量子能量通过计数管转换成具有一定幅度的脉冲电压，然后进行放大等，最后将电脉冲强度记录下来。在X射线荧光分析方面与电子探针分析方面，由记录下来的电脉冲，进行元素的定性定量分析。探测器在原子能方面和X射线结构分析方面也有着广泛的应用。
相关技术中，常用的探测器有盖革-米勒计数管等，探测器是观察、记录粒子的装置，核物理和粒子物理实验研究中不可缺少的设备。其通常结构是在一根两端用绝缘物质密闭的金属管内充入稀薄气体(通常是掺加了卤素的稀有气体，如氦、氖、氩等)，在沿管的轴线上安装有一根金属丝电极，并在金属管壁和金属丝电极之间加上略低于管内气体击穿电压的电压。这样在通常状态下，管内气体不放电；而当有高速粒子射入管内时，粒子的能量使管内气体电离导电，在丝极与管壁之间产生迅速的气体放电现象，从而输出一个脉冲电流信号。通过适当地选择加在丝极与管壁之间的电压，就可以对被探测粒子的最低能量，从而对其种类加以甄选。在相关技术中，一般可以使用α/β样品计数器同时对α粒子和β粒子进行辐射测量，并自动记录测量结果。
然而，发明人发现相关技术中至少存在如下技术问题：
在相关技术中，当存在气体漏气等情况导致气体压力不稳定或气体压 力过大时，往往不能够及时被发现，长此以往，气体很容易穿透探测器从而造成探测器的损坏，导致设备的稳定性不高；一旦其中的一个或多个探测器发生损坏而***气体压力保持原有状态的情况下，其他探测器由于要分担该发生损坏的探测器的气体流量而需要承受较大的压力，随即其他探测器也会发生损坏，而市面上的一个探测器的价格为2万元不等，较为昂贵，因此若探测器损坏，则由之造成的更换、维护成本等费用较高。
发明内容
本申请的一个目的是提供一种探测器的保护***，至少用以解决探测器容易损坏，设备稳定性不高、、维护费用较高等相关技术问题。
为实现上述目的，本申请的一些实施例提供了一种探测器的保护***，所述***包括：气压稳定装置、质量流量控制模块、开关控制模块、探测器、第一流量测量模块、气体单向控制模块；其中，所述开关控制模块、所述探测器、所述第一流量测量模块和气体单向控制模块的数量均为N个，所述N为大于1的整数；所述气压稳定装置的输出端与所述质量控制模块的输入端连接，每个所述开关控制模块、所述探测器、所述第一流量测量模块和气体单向控制模块依次连接形成气体支路，各气体支路之间并联连接，各气体支路的输入端分别与所述质量控制模块的输出端连接，各所述气体支路的输出端设置为进行气体输出；所述气压稳定装置，设置为控制进气气体的气压至气压稳定；所述质量控制模块，用于在气压稳定时，按照预设流量输送气体，以使所述气体被输送至各气体支路；所述开关控制模块，设置为控制对应气体支路的通断；所述第一流量测量模块，设置为测量对应气体支路中，经所述探测器和所述气体反应后的气体流量，以供所述***检测所述气体流量是否存在异常；所述气体单向控制模块，设置为控制对应气体支路的气体进行单向输出；其中，当所述***检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，并控制存在异常的所述气体流量所对应的气体支路的开关控制模块，以使所述对应的气体支路断开。
本申请的一些实施例还提供了一种探测器的保护方法，应用在上述所 述的***，所述方法包括：控制进气气体的气压至气压稳定；在气压稳定时，按照预设流量输送气体，以使所述气体被输送至各气体支路；分别测量各气体支路中的气体流量，以检测所述气体流量是否存在异常，以及控制各气体支路的气体进行单向输出；其中，当检测到所述气体流量存在异常时，自动调整所述预设流量的大小，并控制存在异常的所述气体流量所对应的气体支路断开。
本申请的一些实施例还提供了一种计算机可读介质，其上存储有计算机程序指令，所述计算机程序指令可被处理器执行以实现上述的方法。
相较于相关技术，本申请实施例提供的方案中，首先通过气压稳定装置控制进气气体的气压至气压稳定，然后在气压稳定时，质量控制模块按照预设流量输送气体，以使所述气体被输送至各气体支路，通过开关控制模块控制对应气体支路的通断，通过第一流量测量模块测量对应气体支路中，经所述探测器和所述气体反应后的气体流量，以供所述***检测所述气体流量是否存在异常，之后通过气体单向控制模块控制对应气体支路的气体进行单向输出，当所述***检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，并控制存在异常的所述气体流量所对应的气体支路的开关控制模块，以使所述对应的气体支路断开。由于本申请实施例中，通过气压稳定装置的压力维稳、质量控制模块的气体流量管控、气体单向控制模块的保障，各环节配合实施，可以提升设备的稳定性；当所述***检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，可以使得一旦其中的一个或多个探测器发生损坏时及时调整***气体压力，使得其他探测器的气体流量保持不变，加之还控制存在异常的所述气体流量所对应的气体支路的开关控制模块，以使所述对应的气体支路断开，因此电离探测器无需承受较大的压力的气体流量，使得其他探测器得到了保护，有利于降低对探测器的更换、维护成本。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本文中使用以下术语。
减压阀：是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节***的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。
二位二通电磁阀，一种直动和先导式相结合的机械原理。电磁阀从原理上分为二大类：1)直动式电磁阀：原理：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。特点：在真空、负压、零压时能正常工作，但通径一般不超过25mm。2)分步直动式电磁阀：原理：它是一种直动和 先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。其中，上述两类二位二通电磁阀均适用本申请实施例。
质量流量控制器，英文全称：Mass Flow Controller，简称“MFC”，是用来对气体或液体的质量流量进行精密测量和控制的仪器。它通常由流量传感器、流量调节阀、放大控制电路和分流器控制通道等部件组成，它的工作电源及流量显示和设定等操作由与其配套的流量显示电源提供。
单向阀，又称止回阀或逆止阀，是气体只能沿一个方向流通，却无法回流的装置。
转子流量计，又称变流通面积恒差压流量计或浮子流量计，是根据节流原理测量流体流量的，但是它是改变流体的流通面积来保持转子上下的差压恒定。
在相关技术中，发明人并未发现针对探测器的保护***，为了改善相关技术中的不足，提出了一种探测器的保护***，以解决在气体存在异常时不能够及时被发现的技术问题，以及长此以往，气体很容易穿透探测器从而造成探测器的损坏，导致设备的稳定性不高的技术问题，本申请实施中的探测器的保护***，不仅可以提高α/β样品计数器等设备的稳定性，还可以降低因探测器损坏而产生的维护成本等费用。
具体地，如图1所示，本申请实施例提供了一种探测器的保护***，所述***包括：气压稳定装置11、质量流量控制模块、开关控制模块13、探测器14、第一流量测量模块15、气体单向控制模块16。其中，所述开关控制模块13、所述探测器14、所述第一流量测量模块15和气体单向控制模块16的数量均为N个，所述N为大于1的整数。
所述气压稳定装置11的输出端与所述质量控制模块的输入端连接，每个所述开关控制模块13、所述探测器14、所述第一流量测量模块15和气体单向控制模块16依次连接形成气体支路，各气体支路之间并联连接， 各气体支路的输入端分别与所述质量控制模块的输出端连接，各所述气体支路的输出端设置为进行气体输出；
所述气压稳定装置11，设置为控制进气气体的气压至气压稳定；
所述质量控制模块，设置为在气压稳定时，按照预设流量输送气体，以使所述气体被输送至各气体支路；
所述开关控制模块13，设置为控制对应气体支路的通断；
所述第一流量测量模块15，设置为测量对应气体支路中，经所述探测器14和所述气体反应后的气体流量，以供所述***检测所述气体流量是否存在异常；
所述气体单向控制模块16，设置为控制对应气体支路的气体进行单向输出；
其中，当所述***检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，并控制存在异常的所述气体流量所对应的气体支路的开关控制模块13，以使所述对应的气体支路断开。
需要说明的是，若探测器的数量增加，则所述***控制所述质量控制模块增大所述预设流量；若探测器的数量减少(比如发生损坏)，则所述***控制所述质量控制模块减小所述预设流量。
在一些例子中，所述气压稳定装置11的输入端和混合气体瓶等气体容器连接。可选地，所述气体容器为P10气体瓶。
在一些例子中，所述质量控制模块12具体为质量流量控制器。
在一些例子中，所述开关控制模块13具体为二位二通电磁阀。
在一些例子中，所述第一流量测量模块15具体为流量传感器。
在一些例子中，所述气体单向控制模块16具体为单向阀。
在一些例子中，所述气体支路的数量为4个、8个、10个、12个。该气体支路的数量可根据实际需求来确定，本申请实施例对此不作具体限定。
具体地说，在气体容器的阀门开启后，所述***的气压稳定装置11接收从气体容器排出的进气气体的气压至气压稳定，然后通过质量控制模块12按照预设流量输送气体，此时N个开关控制模块13自动开启，所述***的气压稳定装置11控制进入所述气体支路的进气气体的气压至气压 稳定，之后，与N个探测器14分别连接的N个第一流量测量模块15将测量到的对应气体支路中，经所述探测器14和所述气体反应后的气体流量上报所述***，之后，气体单向控制模块16控制对应气体支路的气体进行单向输出，这样可以防止外部气体进入至所述气体支路中进而出现所述气体支路的气体和外部气体混合，导致测量结果不准确的现象。
进一步地，当第一流量测量模块15检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，并控制存在异常的所述气体流量所对应的气体支路的开关控制模块13，以使所述对应的气体支路断开。
举例而言，假设气体支路的数量为4个，分别为气体支路A～气体支路D，预设流量为240ml/min，则每个气体支路的正常流量则为60ml/min，各气体支路对应的开关控制模块13、探测器14、第一流量测量模块15、质量控制模块12、气体单向控制模块16分别为：开关控制模块A～开关控制模块D、探测器A～探测器D、第一流量测量模块A～第一流量测量模块D、质量控制模块A～质量控制模块D、气体单向控制模块A～气体单向控制模块D。若存在漏气或者探测器A漏气膜破的现象，则气体支路A的第一流量测量模块A可以检测到所述气体流量数据，并将所述气体流量数据上报***，***分析上报数据确定存在异常后，控制调整质量控制模块A自动调整所述预设流量的大小，比如将预设流量自动减少为180ml/min，及时保护气体支路B～气体支路D的气体流量在正常范围，从而避免因探测器B～探测器D受到过大的气体压力而损坏。同时，***对应关闭开关控制模块A，这样不仅可以关断存在异常的气体支路，还可以避免***工作中使用的气体的浪费。至此，当***中的某一或某些气体支路存在异常时，可以保护到其他气体支路的探测器14，使其他气体支路可以正常工作，不影响用户的使用。
不难发现，与相关技术相比，本申请实施例提供的探测器的保护***，首先通过气压稳定装置控制进气气体的气压至气压稳定，然后在气压稳定时，质量控制模块按照预设流量输送气体，以使所述气体被输送至各气体支路，通过开关控制模块控制对应气体支路的通断，通过第一流量测量模块 测量对应气体支路中，经所述探测器和所述气体反应后的气体流量，以供所述***检测所述气体流量是否存在异常，之后通过气体单向控制模块控制对应气体支路的气体进行单向输出，当所述***检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，并控制存在异常的所述气体流量所对应的气体支路的开关控制模块，以使所述对应的气体支路断开。
由于本申请实施例中，通过气压稳定装置的压力维稳、质量控制模块的气体流量管控、气体单向控制模块的保障，各环节配合实施，可以提升设备的稳定性；当所述***检测到所述气体流量存在异常时，所述***控制所述质量控制模块调整所述预设流量的大小，可以使得一旦其中的一个或多个探测器发生损坏时及时调整***气体压力，使得其他探测器的气体流量保持不变，加之还控制存在异常的所述气体流量所对应的气体支路的开关控制模块，以使所述对应的气体支路断开，因此电离探测器无需承受较大的压力的气体流量，使得其他探测器得到了保护，有利于降低对探测器的更换、维护成本。
在本申请一些实施例中，所述质量控制模块的数量为N个；每个所述质量控制模块和每个所述开关控制模块13一一对应连接。
其中，质量控制模块的数量和气体支路的数量相同，每个质量控制模块控制每个气体支路的气体流量。假设气体支路的数量为4个，分别为气体支路A～气体支路D，预设流量为240ml/min，则每个气体支路的正常流量则为60ml/min，各气体支路对应的质量控制模块12、开关控制模块13、探测器14、第一流量测量模块15、气体单向控制模块16分别为：质量控制模块A～质量控制模块D、开关控制模块A～开关控制模块D、探测器A～探测器D、第一流量测量模块A～第一流量测量模块D、质量控制模块A～质量控制模块D、气体单向控制模块A～气体单向控制模块D，这里，每个质量控制模块控制的气体流量为60ml/min。
可以参见图2所示，图2示出了一种应用实例中的探测器的保护***的电路连接示意图。该例子中气体支路的数量为4个，各气体支路对应的 质量控制模块12、开关控制模块13、探测器14、第一流量测量模块15、气体单向控制模块16分别为：质量控制模块A～质量控制模块D、开关控制模块A～开关控制模块D、探测器A～探测器D、第一流量测量模块A～第一流量测量模块D、质量控制模块A～质量控制模块D、气体单向控制模块A～气体单向控制模块D。假设预设流量为240ml/min，由于气体支路的数量为4个，则每个质量控制模块控制的气体流量为60ml/min。

在一些例子中，所述第二减压模块具体为三级减压阀。
在一些例子中，若气体支路的数量为4，则所述第一压力值0.2兆帕左右，第二压力值为0.05兆帕左右。
具体地说，在人工开启气体容器的阀门并开启所述第一减压模块后，所述第一减压模块接收从气体容器排出的进气气体，对所述进气气体的气压进行减压至第一压力值，然后***自动开启排气开关，所述1-2分气模块将压力为所述第一压力值的气体分为两路气体，其中一路气体作为填充气体将***本来既有的余气通过排气开关排出，直到所述余气排尽至气压 稳定后，所述***自动开启第二减压模块，所述第二减压模块将输入的气压进行减压至第二压力值后，将压力为所述第二压力值的气体输入至质量控制模块12，质量控制模块12按照预设流量输送气体，此时***自动开启N个开关控制模块13先将输送的气体作为填充气体将***本来既有的余气排出直至所述***的气压稳定，在所述***的气压稳定后，***自动关闭所述排气开关。至此，气压稳定装置11实现了对***进气气体的气压进行气压稳定的控制。

在本申请一些实施例中，所述质量控制模块的数量为1个；所述质量控制模块的输出端通过分气模块和各所述气体支路的输入端连接。
具体地说，在本申请实施例中，质量控制模块的数量为1个。假设气体支路的数量为4个，所述质量控制模块的输出端通过分气模块将所述质量控制模块输出的气体流量平均分为4份，然后通过分气模块和各所述气体支路的输入端连接。也就是说，假设预设流量为240ml/min，则分气模 块将该240ml/min的预设流量平均分为4份60ml/min的流量，并将该60ml/min的流量分别输出至该4个气体支路。
可以如图4所示，图4示出了一种应用实例中的探测器的保护***的电路连接示意图。该例子中，气体支路的数量为4个，所述质量流量控制器的输出端通过1-4分气模块将气体流量平均分为4份，然后通过1-4分气模块和各所述气体支路的输入端连接。也就是说，假设预设流量为240ml/min，则1-4分气模块将该240ml/min的预设流量平均分为4份60ml/min的流量，并将该60ml/min的流量分别输出至该4个气体支路。
其中，需要说明的是，在其他例子中，若气体支路的数量为8个，则可以使用1-8分气模块；若气体支路的数量为12个，则可以使用1-12分气模块，以此类推。
不难发现，本申请实施例为与图2所对应的实施例并列的***实施例，由于质量控制模块的成本较高，本申请实施例中，通过将质量控制模块的数量设置为1个并通过分气模块的辅助将气体流量平分并传输至各支路，有利于降低成本。

在本申请一些实施例中，所述***具体设置为在检测到所述气体流量存在异常时，根据所述预设流量和存在异常的所述气体支路的数量，控制所述质量控制模块调整所述预设流量的大小。
举例而言，假设预设流量为480ml/min，预设气体支路的数量为8个，则各支路的气体流量为60ml/min，若其中的1个支路的气体流量存在异常， 则质量控制模块可以将所述预设流量调整为480ml/min；若其中的2个支路的气体流量存在异常，则质量控制模块可以将所述预设流量调整为420ml/min。

在一些例子中，所述第二流量测量模块具体为转子流量计。
具体地说，假设气体支路的数量为4个，分别为气体支路A～气体支路D，预设流量为240ml/min，则每个气体支路的正常流量则为60ml/min，如果***运行正常，不存在漏气或者探测器A漏气未发生膜破的现象，则合气模块汇聚各所述气体支路输出的气体的流量应当为240ml/min，并将该240ml/min的测量结果展示出来。否则，若合气模块汇聚各所述气体支路输出的气体的流量为180ml/min，则说明其中的一个气体支路存在异常，通过将该180ml/min展示出来，方便相关工作人员知晓当前***的运行状态。
在一些例子中，具体将测量结果展示于***运行所依托的设备的显示屏上。
可以如图5所示，图5示出了一种应用实例中的探测器的保护***的电路连接示意图。在该例子中气体支路的数量为4个，假设预设流量为240ml/min，则每个气体支路的正常流量则为60ml/min，如果***运行正常，不存在漏气或者探测器A漏气未发生膜破的现象，则1-4合气模块汇 聚各所述气体支路输出的气体的流量，并通过转子流量计进行测量的测量结果应当为240ml/min，并将该240ml/min的测量结果展示出来。否则，若1-4合气模块汇聚各所述气体支路输出的气体的流量，并通过转子流量计进行测量的测量结果为180ml/min，则说明其中的一个气体支路存在异常，通过将该180ml/min展示出来，方便相关工作人员知晓当前***的运行状态。
不难发现，本申请实施例中，通过配合使用合气模块和第二流量测量模块，使所述***展示所述测量结果，方便相关工作人员可以直观的了解当前***的运行状态，方便提升相关工作人员的工作效率。
