At this time, the signal acquisition work between the cable cores 1 and 2 is completed; use the same method to sequentially collect the cores 1 and 3, and the cores 1 and 4 No. 2 and No. 3 cores, No. 2 and No. 4 wire cores, and the voltage signals between No. 3 and No. 4 wire cores are included in the corresponding registers of the main controller; The data is matched, and the wiring situation is judged in the order of open circuit inspection→short circuit inspection→wrong wire inspection. The judgment is based on the following: Take the data between the cores of No. , Reverse two signal acquisitions, the forward signal should be the analog voltage 12*10/(10+10)=6v, the reverse signal is the analog voltage 0v because there is a diode in the test element unit, first judge the open circuit .
1)断路检查:若1、2号线芯之间出现断路则采集电路无法接通,正向、反向采集到的数据均应为0v,若1号线断路,所有与1号线有关的采集电路均无法采集到电压信号,此时1、2号线芯,1、3号线芯,1、4号线芯的正向、反向采集信号均应为0v,故判断出1号线芯接头处存在断路情况;若2号线断路,所有与2号线有关的采集电路均无法采集到电压信号,此时1、2号线芯,2、3号线芯,2、4号线芯的正向、反向采集信号均应为0v,故判断出2号线芯接头处存在断路情况,若1、2号线出现断路情况则计入查线报告中1) Open circuit check: If there is an open circuit between the No. 1 and No. 2 cores, the acquisition circuit cannot be connected, and the data collected in the forward and reverse directions should be 0v. If the No. 1 line is disconnected, all related to No. 1 line The acquisition circuit cannot collect voltage signals. At this time, the forward and reverse acquisition signals of No. 1 and No. 2 wire cores, No. 1 and No. 3 wire cores, and No. 1 and No. 4 wire cores should be 0v, so it is judged that No. 1 wire There is an open circuit at the core connector; if line 2 is open, all the acquisition circuits related to line 2 cannot collect voltage signals. At this time, cores 1 and 2, cores 2 and 3, and lines 2 and 4 Both the forward and reverse acquisition signals of the core should be 0v, so it is judged that there is an open circuit at the connector of the No. 2 core, and if there is an open circuit on the No.
2)短路检查:若1、2号线出现短路情况则测试元件单元无法接入采集电路,采集单元内的电阻与二极管均无法工作,电源电压全部分到10kΩ定值电阻上,主控芯片采集到的电压应为12v,且正向、反向采集到的电压应相等且均为12v,由此判断出1、2号线芯间存在短路情况,计入查线报告中;2) Short circuit inspection: If there is a short circuit on line 1 and line 2, the test component unit cannot be connected to the acquisition circuit, and the resistors and diodes in the acquisition unit cannot work. The received voltage should be 12v, and the forward and reverse collected voltages should be equal and both 12v, so it can be judged that there is a short circuit between the cores of line 1 and line 2, and it will be included in the line inspection report;
3)若1、2号线芯间无短路、断路情况出现则进入错线检查,将正向采集到的电压信号与1、2号线芯间正确采集电压即6v做匹配,若电压值相等则判明接线正确,将1、2号线间接线正确计入查线报告中,若不等于6v则依次将其与1、3号线芯,1、4号线芯,2、3号线芯,2、4号线芯,3、4号线芯间正确采集电压值做匹配,此时如果匹配结果是1、2号线芯采集电压数值与1、4号线芯间正确采集电压值一致则判明2号线芯与4号线芯错线,将结果计入查线报告中,若均不匹配则判断其值是否为0v若是0v则将1、2号线芯间反向采集电压值调出将其与1、2号线芯,1、3号线芯,1、4号线芯,2、3号线芯,2、4号线芯,3、4号线芯间标准采集电压值进行匹配,若1、2号线芯间反向采集电压值与1、2号线芯间正确采集电压值一致则判明1号线芯与2号线芯错线,2号线芯与1号线芯错线,则判明1、2号线芯反接(即1A与2B端连接在一起,2A与1B间连接在一起)将结果计入查线报告中。3) If there is no short circuit or open circuit between the 1st and 2nd line cores, enter the wrong line inspection, and match the voltage signal collected in the forward direction with the correct collected voltage between the 1st and 2nd line cores, which is 6v. If the voltage values are equal Then it is determined that the wiring is correct, and the wiring between line 1 and line 2 is correctly included in the line inspection report. If it is not equal to 6v, it is connected with line cores 1 and 3, line cores 1 and 4, and line cores 2 and 3 in turn. , No. 2, No. 4 wire cores, No. 3, No. 4 wire cores correctly collect voltage values for matching. At this time, if the matching result is that the collected voltage values of No. 1 and No. 2 cores are consistent with the correct collected voltage values between No. 1 and No. 4 wire cores Then it is determined that the No. 2 core and the No. 4 core are miswired, and the result is included in the line inspection report. If they do not match, then judge whether the value is 0v. If it is 0v, reversely collect the voltage value between the No. 1 and No. 2 cores. Call out the standard collection voltage between it and No. 1 and No. 2 wire cores, No. 1 and No. 3 wire cores, No. 1 and No. If the reverse collected voltage value between No. 1 and No. 2 cores is consistent with the correct collected voltage value between No. 1 and No. 2 cores, then it is determined that No. 1 and No. 2 cores are miswired, and No. 2 and No. 1 If the No. 1 and No. 2 cores are miswired, it is determined that the No. 1 and No. 2 cores are reversely connected (that is, the 1A and 2B terminals are connected together, and the 2A and 1B terminals are connected together).

One, respectively installed on the interface at both ends of the system A, B, first plug one end of the cable into the B-end socket, and then plug the other end of the cable into the A-end socket to complete the connection between the cable and the line checking system; Sometimes there is no power supply on site during installation. The system can be powered by internal power supply. If there is AC 220v power supply, connect the line checking system to the power supply, turn on the power switch of terminal A to turn on the system power supply, and the system will initialize and automatically detect.

1)断路检查:若1、2号线芯之间出现断路则采集电路无法接通,正向、反向采集到的数据均应为0v,若1号线断路,所有与1号线有关的采集电路均无法采集到电压信号,此时1、2号线芯,1、3号线芯,1、4号线芯,1、5号线芯1、6号线芯间的正向、反向采集信号均应为0v,故判断出1号线芯接头处存在断路情况;若2号线断路,所有与2号线有关的采集电路均无法采集到电压信号,此时1、2号线芯,2、3号线芯,2、4号线芯2、5号线芯,2、6号线芯的正向、反向采集信号均应为0v,故判断出2号线芯接头处存在断路情况,若1、2号线出现断路情况则计入查线报告中1) Open circuit check: If there is an open circuit between the No. 1 and No. 2 cores, the acquisition circuit cannot be connected, and the data collected in the forward and reverse directions should be 0v. If the No. 1 line is disconnected, all related to No. 1 line The acquisition circuit cannot collect the voltage signal. At this time, the forward and reverse directions between No. 1 and No. 2 wire cores, No. 1 and No. 3 wire cores, No. 1 and No. All the acquisition signals in both directions should be 0v, so it is judged that there is an open circuit at the core connector of line 1; if line 2 is open, all the acquisition circuits related to line 2 cannot collect voltage signals. core, No. 2 and No. 3 cores, No. 2 and No. 4 cores, No. 2 and No. 5 cores, and No. 2 and No. 6 cores. If there is a circuit breaker, if there is a circuit breaker on Line 1 and Line 2, it will be included in the line inspection report
2)短路检查:若1、2号线出现短路情况则测试元件单元无法接入采集电路,采集单元内的电阻与二极管均无法工作,电源电压全部分到10kΩ定值电阻上,主控芯片采集到的电压应为12v,且正向、反向采集到的电压应相等且均为12v,由此判断出1、2号线芯间存在短路情况,计入查线报告中;2) Short circuit inspection: If there is a short circuit on line 1 and line 2, the test component unit cannot be connected to the acquisition circuit, and the resistors and diodes in the acquisition unit cannot work. The received voltage should be 12v, and the forward and reverse collected voltages should be equal and both 12v, so it can be judged that there is a short circuit between the cores of line 1 and line 2, and it will be included in the line inspection report;
3)若1、2号线芯间无短路、断路情况出现则进入错线检查,将正向采集到的电压信号与1、2号线芯间正确采集电压即6v做匹配,若电压值相等则判明接线正确,将1、2号线间接线正确计入查线报告中,若不等于6v则依次将其与1、3号线芯,1、4号线芯,1、5号线芯,1、6号线芯,2、3号线芯,2、4号线芯2、5号线芯,2、6号线芯,3、4号线芯,3、5号线芯,3、6号线芯,4、5号线芯,4、6号线芯,5、6号线芯间正确采集电压值做匹配,此时如果匹配结果是1、2号线芯采集电压数值与3、6号线芯间正确采集电压值一致则判明1号线芯与3号线芯错线,2号线芯与6号线芯错线,将结果计入查线报告中,若均不匹配则判断其值是否为0v若是0v则将1、2号线芯间反向采集电压值调出将其与1、2号线芯,1、3号线芯,1、4号线芯,1、5号线芯,1、6号线芯,2、3号线芯,2、4号线芯2、5号线芯,2、6号线芯,3、4号线芯,3、5号线芯,3、6号线芯,4、5号线芯,4、6号线芯,5、6号线芯间标准采集电压值进行匹配,若1、2号线芯间反向采集电压值与3、4号线芯间正确采集电压值一致则判明1号线芯与4号线芯错线,2号线芯与3号线芯错线,将结果计入查线报告中。3) If there is no short circuit or open circuit between the 1st and 2nd line cores, enter the wrong line inspection, and match the voltage signal collected in the forward direction with the correct collected voltage between the 1st and 2nd line cores, which is 6v. If the voltage values are equal Then it is determined that the wiring is correct, and the wiring between line 1 and line 2 is correctly included in the line inspection report. If it is not equal to 6v, it is connected with line cores 1 and 3, line cores 1 and 4, and line cores 1 and 5 in turn. , No. 1, No. 6 wire core, No. 2, No. 3 wire core, No. 2, No. 4 wire core 2, No. 5 wire core, No. 2, No. 6 wire core, No. 3, No. 4 wire core, No. , No. 6 wire core, No. 4, No. 5 wire core, No. 4, No. 6 wire core, and No. 3. If the correctly collected voltage values between the No. 6 wire cores are consistent, it is determined that the No. 1 wire core and No. 3 wire core are miswired, and the No. 2 wire core and No. 6 wire core are miswired. If it matches, it is judged whether its value is 0v, if it is 0v, the reversely collected voltage value between No. 1 and No. 2 cores is called out, and it is compared with No. 1, No. 5 core, 1, 6 core, 2, 3 core, 2, 4 core 2, 5 core, 2, 6 core, 3, 4 core, 3, No. 5 wire core, No. 3, No. 6 wire core, No. 4, No. 5 wire core, No. 4, No. 6 wire core, standard collection voltage value between No. If the collected voltage value is consistent with the correct collected voltage value between No. 3 and No. 4 cores, then it is determined that No. 1 and No. 4 cores are miswired, and No. 2 and No. 3 cores are miswired. The results will be included in the line inspection report. .
此时完成1、2号线芯接线情况判断进入下一步判断1、3号线芯间接线情况。依此类推将1、3号线芯,1、4号线芯,1、5号线芯,2、3号线芯,2、4号线芯2、5号线芯,3、4号线芯,3、5号线芯,4、5号线芯间接线情况全部判断完毕后整理查线报告,将其显示在显示器内完成此次查线。查线报告分为三部分即断路指示、短路指示和错线指示,如多芯电缆出现1号线芯断线,2号线芯与4号线芯错接3号线芯与5号线芯短路6号线芯正常则报告提示为:“断路:1号线芯;短路:3→5;错线:2A→4B,4A→2B”。At this point, the judgment of the wiring status of the 1st and 2nd wire cores is completed and the next step is to judge the wiring status of the 1st and 3rd wire cores. By analogy, wire cores 1 and 3, wire cores 1 and 4, wire cores 1 and 5, wire cores 2 and 3, wire cores 2 and 4, wire cores 2 and 5, and wires 3 and 4 Core, No. 3 and No. 5 cores, and No. 4 and No. 5 cores are all judged. After the line inspection report is completed, it will be displayed on the display to complete the line inspection. The wire checking report is divided into three parts: open circuit indication, short circuit indication and wrong wire indication. For example, if the wire core 1 of the multi-core cable is disconnected, the wire core 2 and the wire core 4 are wrongly connected to the wire core 3 and the wire core 5. If the short-circuit of the No. 6 core is normal, the report prompts: "Open circuit: No. 1 core; Short circuit: 3→5; Wrong wire: 2A→4B, 4A→2B".
