摘　要：电磁感应装定方式，装定精度和可靠性比较高，它能够在一条回路内完成能量的感应、信息的装定和反馈，在感应装定设计中被大量采用。某末制导炮弹是末制导炮弹系列产品的外贸型号之一，在测试或发射前，需对其远近区、时间、引信状态开关、导引头编码等参数进行装定。该末制导炮弹的装定首次采用电子感应装定的方式。在装配过程中出现了装定查询错误的现象，导致末制导炮弹无法正常发射。针对装配及试验过程中出现的装定查询错误的现象，通过问题分析，查找出故障原因，并针对故障原因采取了有效的措施，大大提高了良品率，确保了感应线圈装定的可靠性。

Abstract：Electromagnetic induction setting mode，high accuracy and reliability，it can complete the energy response，information setting and feedback in one circuit，and is widely used in the design of the induction set⁃ting.The terminal guided prjectile is one of the foreign trade models of the terminal guided projectile series.Be⁃fore testing or launching，it is necessary to fix the range，time，fuse state switch and seeker coding should be set.For the first time，the terminal guided projectile is set by electronic.In the process of assembly，the fixed query error occurred，which caused the terminal guided projectile to fail to fire normally.In response to errors in the assembly and testing proces.Through the problem analysis，find out the fault，and take effective measures for the cause of the fault，greatly improve the rate of good quality，ensure the reliability of the induction coil setting.
