水闸闸门开度显示异常故障的分析与排除

Analysis and Elimination of Abnormal Failure of the Sluice Gate Opening

闸门控制系统故障将影响着水闸的正常运行,进而影响水闸工程效益的发挥,文章提出了闸门运行时导致闸门开度显示异常故障的原因是多样的,触摸屏、电路传输、编码器、传感器或机械传动装置任一方面出现问题都有可能导致此类故障的发生,通过分析排查确认此次问题出在机械传动装置方面,更换或修复相应的机械传动装置后排除了故障,同时分析了防止此类故障发生的有利条件或者排除此类故障的一般思路方法,确保水闸正常运行,发挥工程效益。

The fault of gate control system will influence the normal operation of sluice and also influence the benefit of this sluice project. The reasons for the fault during the normal operation are diverse. Problems in touch screen,circuit transmission,encoder,sensor or mechanical transmitting device may cause this kind of fault. It is confirmed that the problem is caused by the mechanical transmitting device after the analysis. After changing and fixing the mechanical transmitting device, the fault is excluded.Meanwhile,the conditions have been analyzed for preventing this fault from happening again,and also the general methods to exlude this fault in order to guarantee the sluice＇s normal operation and make benefits of the sluice.
