The Design of Multi-Motor Synchronous Monitoring System Based on IOT

In order to improve the quality of network monitoring, the monitoring design of the multi-motor synchronization control system based on IOT was present. In the paper IOT technology was adopted. The server part was completed on PC. And the client system was implemented on Android smart phone platform. And the motor control parameters were saved in text mode. Various parameters of multi motor synchronous system were monitored in text and graphics on Android smart phone. The parameter changes of the master motor speed and the tension were monitored on-line and shown in data curve mode. Users could browse in real time by mobile phone. Users could use manual / automatic two control methods to implement real-time control on the system. The communication parameters were stored in SQLite database. Socket network communication based on message notification was used in the system. More and more experiments showed that: The monitoring system was cost-effective, and good real-time performance. And the same time the system was quickly, low demand on the network, and easy to use.

Research on Adaptive Load Sharing Control for Multi-Motor Synchronous Driving System of Shield Machine

This paper presents an adaptable controlling approach on account of the mathematic modeling and the quantitative analysis of experimental data on a ring-coupling controlling structure. It is based on the research of transmission characteristics of non-linear coupling gear rotation in main electric-driving system of cutterhead, and it is aimed at reducing the deviation of system synchronization caused by the mutation load, and improving the compliance capability of multi-motor synchronization system.
