Research On Automatic Alignment Of Miter Gate Opening Dislocation Based On PLC

With the continuous promotion of One Belt And One Road strategy,the development of the Yangtze River economic belt has been highly valued,and the Yangtze River shipping industry has been developing rapidly.As an important navigation hub in the Yangtze river basin,high head ship lock plays a decisive role in navigation efficiency.High head ship lock miter gate clearance after the end of the crack and the mismatch between the two fan miter gate is to ensure that the normal pressure after water miter gate closed,the lock joint program running two very important technical indicators if the two technical indicators appear larger deviation,can affect the folded effect of miter gate,led to the suspension of ship lock linkage procedure in the process of running,such as mechanical overload problem,serious when still can cause permanent damage to metal structure of the miter gate,the cause of these problems have seriously affected the shipping navigation efficiency,based on the research of the dislocation gate door automatic calibration device,miter gate would significantly reduce the crack of the dislocation,failure rate brings to the safe operation of the high head lock technical support,thus to protect navigation efficiency,the realization of miter gate door automatic calibration function of dislocation,and the adjustment of the miter gate for the crack of the dislocation technology provides a more reliable.The main work of this paper is summarized as follows:(1)Dislocation effects of high head lock miter gate door adjustment "analysis of the factors associated with persons miter gate door automatic calibration of dislocation will need to find out the related factors influencing the displacement adjustment miter gate the crack of the door,the relative changes of miter gate the crack of the dislocation was studied,and the miter gate door dislocation of repeatability and the change of pressure water after finishing analysis,found the relationship exists Then simulate the miter gate drive main motor running with door four bar linkage motion relationship,specific analysis of the miter gate drive motor operation and the relationship between the crack of the dislocation,at the same time according to the actual working status of the late and the need of automatic control implementation,completed the existing laser ranging device optimization work,for subsequent research.(2)Miter gate door dislocation the overall design of the automatic calibration scheme of miter gate door dislocation of automatic calibration function,you need to the PLC programming method in the field of automation and logical program design more in-depth understanding and learning in high head ship miter gate door dislocation,on the basis of existing software adjustment,according to the preliminary work to collect data and analysis of miter gate dislocation crack detection device for the optimization of software and hardware research,in accord with the safe operation of the high head lock conditions under the premise of high head door dislocation of ship locks is determined,the reasonable interval value and the optimal value,early access to large amounts of data and then through the analysis,find out the miter gate after the lock chamber pressure water of miter gate under the complicated condition of the crack of the dislocation of the related influencing factors,to ensure that the lock chamber in the process of water level is gradually increased,the crack of the door of the miter gate of misalignment values has been in a reasonable range,will not affect the ship lock of normal running finally find out of miter gate door dislocation for regulating the relationship between the logic of the formation of the miter gate misalignment automatically adjust the feasible scheme for the adjustment of this is the main content of this study.(3)Miter gate door dislocation and field test on the basis of write eventually to achieve the function of the complete process design and logical design of the automatic calibration procedures,and insight into the study of the existing lock operation regulation centralized control system,complete the miter gate door dislocation,write,and with the help of a ship lock operation management related technicians,remit the corresponding PLC ladder diagram,and embedding procedure of centralized control system in the real-time operation,persons involved miter gate door dislocation in-situ tests of automatic adjustment of the work.
