基于PLC的三维调整机同步控制系统设计与实现

针对三维调整机难以实现多台同步工作，设计了基于PLC的同步控制方案。在同步控制系统方案中，采用西门子PLC通过工业无线以太网进行同步控制，由各维度油缸的位移传感器来保证同步控制的精确性。经实验，证实了此系统的精度满足设计要求，实现了同步控制的效果。

Design and implementation of three dimensional adjusting machine synchronous control system based on PLC

In order to solve the present situation of low accuracy of artificial joint closure in segmented shipbuilding mode, put forward a multi machine synchronous control method of three-dimensional adjustment machine, design the synchronization control scheme based on Siemens S7-200 PLC and industrial wireless Ethernet. In the scheme of synchronization control system, read and calculation condition data by using PLC, and the calculation results were transferred into the dimensions of the cylinder displacement value, while the cylinder built-in displacement sensor will be the result of the action of feedback to the PLC closed-loop control, so as to ensure the accuracy of synchronous control. Using industrial wireless Ethernet as the transmission medium of data, the operator can change the position flexibly, which is convenient and practical. In the experiment, a system composed of 4 machines, respectively X, Y, Z of cylinder three directions were tested, the results show that the system can be stably moving, lifting action, the same direction of the cylinder synchronization error of each machine meets design requirements in the action process, achieved synchronous control effect.
