配线检测系统及配线检测方法Wiring detection system and wiring detection method

【技术领域】【Technical field】

本发明涉及机电及通讯制造领域，尤其是指生产过程中的检测系统及检测方法。The invention relates to the fields of electromechanical and communication manufacturing, in particular to a detection system and a detection method in the production process.

【背景技术】【Background technique】

在产品生产过程中总会因为各种原因而存在不良品，在电梯制造过程中，配线操作是一个严谨且繁复的工序，如有操作错误则会导致整个配线出现问题无法运作，在生产过程最后一环就是要对配线进行检测，避免有问题的产品流出市面并且对生产过程中的问题及时发现及时纠正。传统操作请参阅图1所示，首先会做好预留测试端子的配线雇，图中W3W、WC1、WB1等为线束的接线端子，在装配时，安排在布线阶段完成装配，需要在平板治具上预留出端子的1∶1装配位置。在电脑LCD屏幕，显示引导布线，根据布线人员观察电脑屏幕所引导的待布线段，从料斗取料，然后根据电脑提示或记忆，将线段布在配线雇上，根据电脑提示顺序，依次布好所有线段，如图2所示。传统的测试仪和检测方法都是在产品生产出来后，再检查产品在制造过程中是否有生产故障产生。这样的检查，虽然能够检查出产品的“故障”位置，仍然不能杜绝故障的产生，对检查出的故障进行“返修”时，也会造成生产成本的增加。一言蔽之，传统的测试仪，是对产品的生产故障进行“被动”的检查。就算花费巨大的检测、返修成本，也期待彻底检查、修复“已经产生的”生产故障。但如果可以在生产过程中及时消除故障的发生，便可大大提高成产良率，并且降低生产成本。In the process of product production, there will always be defective products due to various reasons. In the process of elevator manufacturing, wiring operation is a rigorous and complicated process. If there is an operation error, the entire wiring will fail to operate. The last link in the process is to inspect the wiring to prevent problematic products from flowing out of the market and to detect and correct problems in the production process in a timely manner. Please refer to Figure 1 for the traditional operation. First, the wiring of the reserved test terminals will be done. In the figure, W3W, WC1, WB1, etc. are the wiring terminals of the wiring harness. The 1:1 assembly position of the terminal is reserved on the jig. On the LCD screen of the computer, the guiding wiring is displayed. According to the wiring personnel's observation of the wiring section guided by the computer screen, the material is taken from the hopper, and then according to the computer prompt or memory, the wiring section is laid on the wiring. All line segments are good, as shown in Figure 2. The traditional tester and detection method are to check whether there is any production failure in the manufacturing process of the product after the product is produced. Although such inspection can detect the "fault" position of the product, it still cannot prevent the occurrence of faults. When "repairing" the detected faults, it will also cause an increase in production costs. In a word, the traditional tester is a "passive" inspection of the production failure of the product. Even if it costs a lot of testing and repairing, it is expected to thoroughly check and repair "already generated" production failures. However, if the occurrence of faults can be eliminated in time during the production process, the yield rate of production can be greatly improved and the production cost can be reduced.

因此，提供一种可杜绝生产故障、降低生产成本、提高生产效率的配线检测方法和配线检测系统实为必要。Therefore, it is necessary to provide a wiring detection method and a wiring detection system that can eliminate production failures, reduce production costs, and improve production efficiency.

【具体实施方式】【Detailed ways】

请参阅图5，本发明配线检测系统包括与计算机串行连接的单片机，单片机与主计算机之间通过串行通信交换命令和数据，采用A/D转换器多路卡及MAX232实现RS232与TTL电平之间的相互转换。单片机电路I/O线，用于与模拟接线板连接。该单片机连接地址锁存器和数据总线驱动器，地址锁存器连接门电路及译码器，系统利用译码器进行地址译码，用于选通各片锁存器。数据总线需加总线驱动器，以增加总线的带负载能力。门电路及译码器和数据总线驱动器通过双向数据锁存器连接接线板。因为一个接线点既可以是始节点，又可以是终节点，所以I/O线应具有双向数据传输功能，故采用双向数据锁存器。如图5所示，该单片机还连接晶振电路和复位电路；并可采用光藕元件进行光电隔离，防止外部干扰信号串入检测系统，提高系统的可靠性。单片机还连接有蜂鸣器以作出声音提示，另外还连接有显示电路作为检测结果的显示输出。Please refer to Fig. 5, the wiring detection system of the present invention comprises the single-chip microcomputer that is serially connected with computer, exchange order and data through serial communication between the single-chip microcomputer and main computer, adopt A/D converter multi-way card and MAX232 to realize RS232 and TTL Interchange between levels. SCM circuit I/O line, used to connect with the analog wiring board. The single-chip microcomputer is connected with an address latch and a data bus driver, and the address latch is connected with a gate circuit and a decoder, and the system uses the decoder to perform address decoding and is used for gating each chip latch. The data bus needs to add a bus driver to increase the load capacity of the bus. Gate circuits, decoders and data bus drivers are connected to wiring boards through bidirectional data latches. Because a connection point can be both a starting node and an ending node, the I/O line should have a bidirectional data transmission function, so a bidirectional data latch is used. As shown in Figure 5, the single-chip microcomputer is also connected to the crystal oscillator circuit and reset circuit; and optocoupler components can be used for photoelectric isolation to prevent external interference signals from entering the detection system and improve system reliability. The single-chip microcomputer is also connected with a buzzer to make a sound prompt, and also connected with a display circuit as a display output of the detection result.

请参阅图6，配线检测方法包括如下步骤：单片机从计算机中串行读取配线方案，然后根据配线方案输出始节点号，并发送测试电信号以便配线操作，然后读入终节点状态，判断检测连接是否完成，如果没有完成则返回继续读入终节点状态，若连接已完成则显示连接完成，最后返回再读取下一个配线方案。Please refer to Figure 6, the wiring detection method includes the following steps: the single-chip microcomputer serially reads the wiring scheme from the computer, then outputs the starting node number according to the wiring scheme, and sends a test electrical signal for wiring operation, and then reads the final node Status, to judge whether the detection connection is completed, if it is not completed, return to continue reading the status of the terminal node, if the connection is completed, it will display that the connection is completed, and finally return to read the next wiring scheme.

其检测原理是计算机根据接线方案，屏幕显示两个接线点M、N的编号，指示操作人员接线，同时将两个点的编号串行传送给单片机检测系统，单片机通过扩展I/O线对M、N进行测试，由始节点M发出测试电信号，然后检测终节点N是否接收到该电信号，如果接收到，则回送‘连接成功信号’给计算机。否则等待工作人员完成接线。The detection principle is that the computer displays the numbers of two connection points M and N on the screen according to the wiring scheme, instructs the operator to connect, and at the same time serially transmits the numbers of the two points to the single-chip microcomputer detection system, and the single-chip computer expands the I/O line to M , N to conduct a test, the start node M sends a test electrical signal, and then detects whether the end node N receives the electrical signal, and if so, sends back a 'connection success signal' to the computer. Otherwise, wait for the staff to complete the wiring.

该方法中系统发送测试电信号以提示配线连接并检测连接准确性，如图3和图4所示，先是做好预留测试端子，布线引导LED指示灯的配线雇，如图3所示，在线束线材的布线方向上设定指示灯，在主干的地方设定“主干线指示灯”，每条线分支的部分设定“支线指示灯”，在起端、止端、料斗上设置“端点指示灯”，当电脑提示布该条线材时，起端、止端、料斗的“端点指示灯”将处于闪烁的常亮状态；“主干线指示灯”、“支线指示灯”顺序循环跳动闪亮；当布好线材，线材测试Passs时，所有指示灯关闭。然后，自动进行下一条布线的提示。可以用不同颜色的指示灯区分主干线、支线、起端、止端、料斗。In this method, the system sends a test electrical signal to prompt the wiring connection and check the connection accuracy, as shown in Figure 3 and Figure 4, first prepare the reserved test terminals, and guide the wiring of the LED indicator light, as shown in Figure 3 Set the indicator light on the wiring direction of the wire harness, set the "main line indicator light" at the trunk, set the "branch line indicator light" at the branch of each line, set Set the "end point indicator light", when the computer prompts to lay out the wire, the "end point indicator light" of the starting end, the end end, and the hopper will be in a blinking state; the sequence of the "main line indicator light" and "branch line indicator light" Circularly jumping and flashing; when the wire is laid and the wire test Passs, all the indicator lights are off. Then, the prompt for the next route is automatically carried out. Different colors of indicator lights can be used to distinguish the main line, branch line, starting end, ending end, and hopper.

布线人员只要从料斗上LED灯闪烁处取料，按配线雇上LED灯闪烁的位置与走向装配线段就行了。当前线段装配好，当前线段测试Pass，指示当前线段的LED灯熄灭；自动进行下一线段的LED灯，取料、布线提示。根据电脑自动控制的顺序，依次快速布好所有线段。The wiring personnel only need to take the material from the flashing LED light on the hopper, and hire the flashing LED light position and walk to the assembly line section according to the wiring. The current line segment is assembled, the current line segment test Pass, and the LED light indicating the current line segment is turned off; the LED light of the next line segment is automatically carried out, and the material picking and wiring prompts are performed. According to the sequence automatically controlled by the computer, all line segments are laid out quickly one by one.

在全部配线方案完成后，可以通过整体测试检测所有连接线，显示是否存在多接、串接等错误。如图7所示，单片机从计算机中串行读取配线方案，然后根据配线方案输出始节点号，并发送测试电信号，然后顺序读入终节点状态，记录终节点状态，判断是否读完终节点，如没读完则返回继续读取和记录终节点状态，若已读完终节点状态就选择下一个始节点号，判断全部节点是否已测试完毕，若没有则返回程序开始步骤串行读取下一配线方案，直至全部节点已测试完毕，分析配线连接状态，显示全部节点连接结果。就可以从现实结果中清楚的了解到整体配线完成情况。After all the wiring schemes are completed, all connecting lines can be detected through the overall test to show whether there are errors such as multi-connection and serial connection. As shown in Figure 7, the MCU serially reads the wiring scheme from the computer, then outputs the initial node number according to the wiring scheme, and sends a test electrical signal, and then sequentially reads the status of the final node, records the status of the final node, and judges whether to read Complete the end node, if you have not finished reading, return to continue reading and recording the state of the end node, if you have read the state of the end node, select the next start node number, judge whether all nodes have been tested, if not, return to the program start step string Read the next wiring scheme in a row until all nodes have been tested, analyze the wiring connection status, and display the connection results of all nodes. You can clearly understand the completion of the overall wiring from the actual results.

The use of the wiring detection system with LED lights strictly implements the process sequence of wiring harness wiring. This makes it possible for each segment of the wire material of the wire harness with loop wiring to basically determine the radius of curvature around the loop. Therefore, the length of each segment of the wire harness can be precisely determined without reserve length.
