技术领域technical field
本发明涉及一种电能表自动化检定流水线表位故障报警及定位方法，属于故障排查领域。The invention relates to a method for alarming and locating a meter position fault on an automatic verification assembly line of an electric energy meter, and belongs to the field of troubleshooting.
背景技术Background technique
当前，电能表已实现了用自动化检定流水线进行检定，电能表自动化检定流水线已经在各个省电力公司层面得到了普及。每条流水线的表位数目有一千个左右，且表位属于故障频率较高的部件。当表位故障后会造成表计的检定结论为不合格，需人工进行复检，在很大程度上增加了工作人员的工作量，所以需要及时对故障表位进行修复。目前工作人员依靠一天一次的日常设备巡视来寻找故障表位并进行修复，但由于流水线表位数目众多且表位故障频率较高，因而日常设备巡视远不能满足及时修复故障表位的需求。所以发明一种能及时发现并定位流水线故障表位的方法在实际工作中尤为重要。At present, the electric energy meter has been verified by automatic verification assembly line, and the automatic verification assembly line of electric energy meter has been popularized at the level of various provincial electric power companies. The number of epitopes in each pipeline is about a thousand, and the epitopes belong to components with high failure frequency. When the epitope fails, the verification conclusion of the meter will be unqualified, and manual re-inspection is required, which greatly increases the workload of the staff, so it is necessary to repair the faulty epitope in time. At present, the staff rely on daily equipment inspections once a day to find faulty epitopes and repair them. However, due to the large number of pipeline epitopes and the high frequency of epitope failures, daily equipment inspections are far from meeting the needs of timely repairing faulty epitopes. Therefore, it is particularly important in practical work to invent a method that can detect and locate pipeline fault epitopes in time.
