Abstract

The invention relates to a multi-axis control system and method for wave simulation. The multi-axis control system for wave simulation comprises a host computer and at least one multi-axis manager. Each multi-axis manager comprises controllers connected by a CAN bus. The host computer issues motion instructions through Ethernet. The host computer is connected to multi-axis controllers through I / O ports. The multi-axis controllers transmit the motion instructions to the corresponding controllers through the CAN buses so that corresponding motions are carried out. The motion instructions are transmitted to the multi-axis managers through Ethernet, and the CAN bus-based multi-axis managers control wave generation units to complete corresponding motions on the basis of the motion instructions. In this way, the real-time performance, accuracy and reliability of wave simulation control can be ensured.

Description

technical field [0001] The invention relates to a multi-axis control system and method for wave simulation. Background technique [0002] At present, the wave simulation control system generally adopts three control methods: bus type, network type and board type, mainly including EtherCAT, SQYNET, RS485 and other field bus systems, industrial Ethernet control system and PC-based motion control card control system. [0003] Among them, the fieldbus system is expensive, the transmission distance is limited, remote control is difficult to realize, and the degree of specialization is high, and it is not easy to be compatible with other equipment; the real-time data transmission of the industrial Ethernet control system is difficult to guarantee, which is easy to cause various pushes. Asynchronous wave boards; motion control systems based on boards are mainly composed of motion control cards and computers, and motion control cards are generally inserted into the PCI / PCIE slots of...
