Description

一种电气连接线缆检测系统及方法 技术领域
本发明涉及电气线缆检测技术领域，尤其涉及一种电气连接线缆检测系统及方法。
背景技术
电气连接线缆是电路中连接各电气设备的接线部件,电气连接线缆包括线缆本体和连接在线缆本体两端的连接器(如航空插头)，线缆本体一般包括绝缘护套和被包覆于绝缘护套内的多根芯线。电气连接线缆在加工完成后，必须检验加工的质量，即检验线缆本体两端的连接器与线缆本体之间连接的可靠性(连接器的插针与线缆本体内部芯线之间的通断)和线缆本体两端的连接器与线缆本体之间连接的准确性(连接器的各插针与线缆本体内的各芯线是否按照规定的线序连接)。
目前，在实际操作中，电气连接线缆的检测方式需要将电气连接线缆两端的连接器分别用万用表的红、黑表笔相连接，通过万用表的通断挡来依次检测连接器的各个插针与线缆本体的各个芯线之间是否连通。现有的电气连接线缆检测方式操作繁琐，检测效率低，且每一根芯线与连接器的插针之间的通断检测都需要人工参与判断，非常的浪费人力，并且人在长时间的机械性判断后很容易出错造成误判；另外，在同一根电气连接线缆里面有几根芯线都连接到一起的时候无法用万用表一次性检测判断出来，即无法一次性判断线序是否准确，需要进行多次检测，不仅检测效率低，也可能因为人为漏检或错检而造成对电气连接线缆检测结果的误判。
因此，亟需一款能够代替人工检测和判断的自动化智能化的电子检测系统来完成电气连接线缆的检测工作。

本发明实施例提供了一种电气连接线缆检测系统，如图1-9所示，该系统包括电源转换模块1、线缆连接模块2、主控MCU3和显示与按键模块4。
电源转换模块1分别与显示与按键模块4、主控MCU3和线缆连接模块2连接，其用于将输入电源电压转换成显示与按键模块4、主控MCU3和线缆连接模块2所需的工作电压。具体地，在本实施例中，电源转换模块1的电路原理图如图5所示，电源转换模块1的输入端输入24V直流电，一方面通过TPS54331电源管理芯片进行DC-DC电源转换后，输出系统需要的5V直流电为系统提供5V直流电源(给线缆连接模块、通讯模块等供电)；5V直流电源再经过LM1117-3.3低压差线性稳压器转换后，输出系统需要的3.3V直流电为系统提供 3.3V直流电源(给主控MCU、通讯模块、显示与按键模块等供电)；另一方面，通过L7812CV三端正压稳压器进行稳压后，输出系统需要的12V直流电为系统提供12V直流电源(给蜂鸣器等供电)。
线缆连接模块2包括控制信号输入端21、第一插接件22、第二插接件23和检测信号输出端24，控制信号输入端21包括多个控制端口，检测信号输出端24包括多个检测端口，第一插接件22和第二插接件23均包括多个插针；第一插接件22的多个插针通过控制信号输入端21的多个控制端口分别与主控MCU3的多个控制信号输出端对应连接，第二插接件23的多个插针通过检测信号输出端24的多个检测端口分别与主控MCU3的多个检测信号输入端对应连接；第一插接件22和第二插接件23分别用于插接待检测电气连接线缆的两端的连接器以对待检测电气连接线缆进行检测。具体地，在本实施例中，线缆连接模块2的电路原理图如图7所示，线缆连接模块2的主要作用是为待检测电气连接线缆提供插接载体，该线缆连接模块2的输入输出均与主控MCU3连接，由主控MCU3的各个控制信号输出端分别控制线缆连接模块2的控制信号输入端21的各个控制端口的通断电，主控MCU3的各个检测信号输入端接收控制线缆连接模块2的检测信号输出端24的各个检测端口输出的电压值，主控MCU3再对接收到的电压值进行处理，从而实现对插接在线缆连接模块2的第一插接件22和第二插接件23之间的待检测电气检测线缆的通断与线序的检测。
主控MCU3用于采用预设的线缆检测算法对插接于第一插接件22和第二插接件23之间的待检测电气连接线缆进行检测得到检测结果，并存储检测结果以及将检测结果发送至显示与按键模块4。具体地，在本实施例中，主控MCU3的电路原理图如图6所示，主控MCU3选用型号为STM32F407VET6的单片机， 该单片机采采用LQFP100封装，即该单片机有100pin，其中40pin用于外部信号的检测(20pin输出、20pin输入)，接到线缆连接模块2的各种接口类型的第一插接件22和第二插接件23上。
显示与按键模块4与主控MCU3连接，其用于显示检测结果，以及用于用户进行参数设置。用户可通过显示与按键模块4进行相关参数的设置，也可通过查看显示与按键模块4来了解当前检测的电气连接线缆的通断和线序是否符合生产要求，即通过查看显示与按键模块4显示的检测结果来直观地了解当前检测的电气连接线缆是否检测合格，无需认为参与电气连接线缆的通断和线序的判断。
具体地，本实施例中，线缆连接模块2的端口检测原理图如图2所示，其中，A点对应第一插接件22中的一个插针(即对应待检测电气连接线缆的一端的连接器中的一个插针)，B点对应第二插接件23中的一个插针(即对应待检测电气连接线缆的另一端的连接器中的一个插针)，即该图示出了检测电气连接线缆的一端的连接器中的一个插针和另一端的连接器中的一个插针之间的通断情况检测原理。从图中可以看出，控制端口可以控制A点电压，当控制端口电压为0V时，三极管Q1截止，A点电压为5V(高电平)；当控制端口电压为5V时三极管Q1导通，A点电压为0V(低电平)。在A点与B点之间接上电气连接洗线缆后，A、B两点电压相同，因此可以在检测端口检测到A点电压是否符合控制端口发出的信号。在A、B点之间的电气连接线缆如果有问题断开时，检测端口的电压就一直是5V不会变化，进而可以判断出AB连接线的通断情况。同理，在本系统中，若增加到多对这样的检测电路，则可以同时检测多根芯线的通断情况，并且将其分为很多组，连接到不同的第一插接件22、第二插接件23上，使 得电气连接线缆直接插在插接件上就可以检测，相对于现有技术中一次只能检测一根芯线的检测方式大大提高了检测效率和准确率。
本实施例的电气连接线缆检测系统，通过线缆连接模块2的第一插接件22和第二插接件23来插接待检测电气连接线缆，通过主控MCU3采用预设的线缆检测算法来对插接于所述第一插接件22和第二插接件23之间的待检测电气连接线缆进行检测，通过显示与按键模块4来进行参数设置及显示检测结果。本发明能够替代人工对加工后的电气连接线缆的通断和线序进行检测和判断，整个检测过程人工只参与电气连接线缆的插拔，不参与记录和判断，检测过程自动化智能化程度更高，操作简单便捷，检测效率大大提高，且有效避免了人工对于检测结果的误判，检测结果更加准确可靠。
具体地，如图1所示，在上一实施例的基础上，在一个实施例中，第一插接件22和第二插接件23设置有多个，且各第一插接件22和各第二插接件23的接口类型不同，各第一插接件22的信号输入端分别与控制信号输入端21连接，各第二插接件23的信号输出端分别与检测信号输出端24连接。通过在线缆连接模块2上设置多个不同接口类型的第一插接件22和第二插接件23，从而可以检测不同类型的电气连接线缆，更好地满足用户需求，有效拓展了本电气连接线缆检测系统的可检测范围。
相应的，对应上一实施例中的多种接口类型的第一插接件22和第二插接件23，所述进行参数设置包括进行线缆检测模式的切换以及线缆类型的选择，其中，线缆检测模式包括学习模式和循环检测模式，即用户可以通过显示与按键模块4来进行线缆检测模式的切换以及线缆类型的选择。
具体地，在一个实施例中，显示与按键模块4为TFT触摸屏，通过TFT触 摸屏实现系统的人机交互功能。如图8所示，为本实施例中TFT触摸屏的电路原理图。显示与按键模块4具体采用型号为TFT-2.8的TFT触摸屏。相应的，对应上一实施例中的多种接口类型的第一插接件22和第二插接件23，显示与按键模块4还用于显示学习模式按键、循环检测模式按键、线缆类型选择按键以及当前选择的线缆类型，用户可以通过点击TFT触摸屏显示的学习模式按键和循环检测模式按键来进行线缆检测模式的切换，也可通过点击TFT触摸屏显示的线缆类型选择按键来循环选择对相应的待检测电气连接线缆的线缆类型，选择的线缆类型会显示在TFT触摸屏上。
具体地，在上述实施例的基础上，在一个实施例中，主控MCU3执行的采用预设的线缆检测算法对插接于第一插接件22和第二插接件23之间的待检测电气连接线缆进行检测得到检测结果的步骤包括：
根据设置的线缆检测模式和线缆类型对控制信号输入端21的多个控制端口进行轮询控制，以对插接于第一插接件22和第二插接件23之间的待检测电气连接线缆的线缆本体各个芯线与线缆本体两端的连接器的各个插针之间的通断和连接线序进行检测得到检测结果，该步骤具体包括如下两种情形：
1、当线缆检测模式为学习模式时，对控制信号输入端21的多个控制端口进行轮询控制，记录检测信号输出端24的多个检测端口输出的第一检测值，将记录的第一检测值和当前选择的线缆类型进行绑定得到当前选择的线缆类型的标准值，存储标准值，其中，学习模式下检测的插接于第一插接件22和第二插接件23之间的待检测电气连接线缆为通过其他检测手段检测合格的电气连接线缆。当系统内没有存储对应的线缆类型的标准值时，可以选择学习模式对通过其他检测手段检测合格的该类型的电气连接线缆的通断和线序进行学习从而得到 该类型的电气连接线缆的标准值，便于后续直接检测该类型的电气连接线缆。这使得本系统能够自学习电气连接线缆通断以及线序情况，方便新电气连接线缆的录入。需要说明的是，所述其他检测手段是指除本系统的检测手段之外的其他能够检测电气连接线缆的手段，例如采用万用表的通断档进行检测。
2、当线缆检测模式为循环检测模式时，对控制信号输入端21的多个控制端口进行轮询控制，记录检测信号输出端24的多个检测端口输出的第二检测值，将记录的第二检测值与预先存储的当前选择的线缆类型对应该的标准值进行比较得到比较结果，并基于比较结果生成检测结果，其中，检测结果用于表征插接于第一插接件22和第二插接件23之间的待检测电气连接线缆的线缆本体各个芯线与线缆本体两端的连接器的各个插针之间的通断情况和连接线序的准确性，检测结果包括接线正确和接线错误，当检测结果为接线错误时，检测结果还包括错误端口的编号及其错误类型，错误类型包括端口断开和端口线序不正确；循环检测模式下检测的插接于第一插接件22和第二插接件23之间的待检测电气连接线缆为未通过其他检测手段检测的电气连接线缆。当系统内存储有待检测类型的电气连接线缆的标准值时，可以直接采用循环检测模式来检测该类型的电气连接线缆。需要说明的是，系统内存储有待检测类型的电气连接线缆的标准值可以是通过学习模式进行自学习存储在系统中，也可以由用户输入至本系统中。
在一个实施例中，如图1所示，电气连接线缆检测系统还包括结果辅助提示模块5，结果辅助提示模块5包括LED提示灯51和蜂鸣器52，LED提示灯51和蜂鸣器52分别与主控MCU3的提示信号输出端连接；主控MCU3还用于根据检测结果输出提示控制信号，以通过提示控制信号控制结果辅助提示模块5输出相应的提示信号。通过设置结果辅助提示模块5来对检测结果进行辅助提 示，便于更好地对操作人员当前检测的电气连接线缆是否合格。具体地，LED提示灯51包括一个红色LED灯和一个绿色LED灯，若当前检测的电气连接线缆合格，则主控MCU3控制绿色LED灯点亮(红色LED灯熄灭)，蜂鸣器52不工作；若当前检测的电气连接线缆不合格，则主控MCU3控制红色LED灯点亮(绿色LED灯熄灭)，蜂鸣器52工作报警。
在一个实施例中，如图1所示，电气连接线缆检测系统还包括通讯模块6，通讯模块6与主控MCU3连接。通过设置通讯模块6，使得外部监控终端(如远程监控PC端)可以通过通讯模块6与本系统的主控MCU3建立通信连接，从而主控MCU3可以将检测结果等数据通过通讯模块6发送至外部监控终端，便于外部监控终端根据检测结果进行产品合格率等数据的统计，外部监控终端也可以通过通讯模块6向主控MCU3发送控制信号(例如系统软件升级控制信号、模式切换信号等)和数据(例如某种类型的电气连接线缆的标准值等)，从而实现对本系统的远程监控。具体地，在本实施例中，通讯模块6的电路原理图如图9所示，通讯模块6的主控芯片采用型号为SP3485的低功耗半双工收发器，该收发器完全满足工业通信常用的RS-485和RS-422串行协议的电气规范，且带负载的情况下数据传输速率可高达10Mbps。
如图3、图4所示，是本发明提供的两个不同的具体实例中电气连接线缆的各个芯线与线缆连接模块的控制信号输入端的各个控制端口、检测信号输出端的各个检测端口之间的对应关系图，下面通过这两个图对本系统的工作原理进一步进行详细阐述。
如图3所示，被检测电气连接线缆接入到本系统(即连接在对应类型的第一插接件22和第二插接件23之间)时，本系统的主控MCU3对控制信号输入端 的各个控制端口进行轮询控制，即轮询控制端口1、2、3……在控制任一控制端口时候，主控MCU3均对检测信号输出的所有检测端口输出的检测值(电压值或电平信号)进行记录。例如线缆类型1中，控制端口1、2、3、4分别对应检测端口A、B、C、D。所有控制端口轮询完成后，将记录的所有的检测值与标准值进行对比，所有检测值正确时则给出的检测结果为“结果正确”；当所有检测值中有不正确的值时则给出的检测结果为“结果错误”，其中不正确的控制端口的编号将在显示与按键模块4上区分显示出来，以便定位不正确的芯线进行维修。同理，检测类型2的电气连接线缆也可以进行比对，从而显示结果。
从线缆类型1和线缆类型2这两种电气连接线缆类型的控制端口和检测端口的对应关系图可以看出，本系统对于控制信号输入端的各个控制端口和检测信号输出端的各个检测端口不需要做一一对应，只要区分开各个检测端口和各个控制端口即可以进行检测。
本系统对电气连接线缆的检测不只是1个控制端口对应1个检测端口，也可以是1个控制端口对应多个检测端口和多个检测端口对应1个检测端口。如图4所示，对于线缆类型3，控制端口1同时对应检测端口A、B，这样的连接方式系统也是允许的，系统会同时记录A、B两个检测端口的状态，用于结束时的判断。另外控制端口4、5同时对应检测端口D，在控制端轮询时，控制端口4和5的对应状态均被记录，用到最后的判断，从而显示出判断结果。
通过上述实施例可知，本系统具有自学习功能，可以在该种类型的电气连接线缆第一次检测时进行自学习。具体地，以图4为例，将线缆类型3的电气连接线缆的两端分别通过第一插接件22和第二插接件23连接控制信号输入端和检测信号输出端，用户通过操作显示与按键模块4进行线缆类型的选择和线缆检测模 式的切换，使系统进如该类型的电气连接线缆的学习模式。本系统的自学习流程如下：
1、初始化控制信号输入端的所有控制端口信号，控制端口1发出信号，检测端口A、B收到信号，记录检测值为A、B；
2、初始化控制信号输入端的所有控制端口信号，控制端口2发出信号，所述检测端口无信号输出，记录检测值为NULL(空值)；
3、初始化控制信号输入端的所有控制端口信号，控制端口3发出信号，检测端口C收到信号，记录检测值为C；
……
一直到所有控制端口都轮询一遍后，将所述检测值保存到存储模块，下次检测该类型的电气连接线缆时直接调用即可。整个过程人工只参与外部接线，不参与记录和判断，这样确保了准确性，而且减少人力成本。
本发明实施例还提供了一种电气连接线缆检测方法，该方法应用于上述任一实施例中的电气连接线缆检测系统，如图10所示，该方法包括如下步骤：
S1，通过显示与按键模块设置待检测电气连接线缆对应的线缆类型，并将线缆检测模式设置为循环检测模式；
S2，将待检测电气连接线缆的两端分别插接于线缆连接模块的对应线缆类型的第一插接件和第二插接件；
S3，主控MCU对线缆连接模块的控制信号输入端的各个控制端口进行轮询控制，并记录线缆连接模块的检测信号输出端的各个检测端口输出的第一检测值；
S4，主控MCU将记录的第二检测值与预先存储的当前选择的线缆类型对应 该的标准值进行比较得到比较结果；
S5，主控MCU基于比较结果生成检测结果；
S6，主控MCU存储检测结果，并将检测结果发送至显示与按键模块，以通过显示与按键模块显示检测结果；
S7，将待检测电气连接线缆的两端分别从线缆连接模块的对应的第一插接件和第二插接件拔除，完成一个电气连接线缆的检测；
S8、循环执行步骤S2-S7，以对属于当前选择的线缆类型的下一个待检测电气连接线缆进行检测。
在一个实施例中，在执行步骤S1之前，该方法还包括如下步骤：
S9，通过显示与按键模块设置待检测电气连接线缆对应的线缆类型，并将线缆检测模式设置为学习模式；
S10，将通过其他检测手段检测合格的电气连接线缆作为待检测电气连接线缆，并将待检测电气连接线缆的两端分别插接于线缆连接模块的对应线缆类型的第一插接件和第二插接件；
