Abstract

The invention discloses a multi-axis motion control system and a control method of the multi-axis motion control system, and relates to the field of mechanical design and the automation technology of the mechanical design. The control system comprises an upper computer, a multi-axis motion control card and an execution mechanism. The upper computer is used for issuing motion commands and receiving and displaying state information of the motion control card. The multi-axis motion control card is used for receiving the motion commands issued by the upper computer and achieving interface communication, pulse output, I / O state management, axis trajectory planning and PLC calculation execution according to the commands. The execution mechanism is used for receiving pulse signals output by the multi-axis motion control card and driving multi-axis motion according to the pulse signals. By the adoption of the system and the method of the system, the programmable characteristic of an FPGA in the motion control card is fully utilized, and PCI interface chip IP cores are integrated; due to the fact that a buffer module with an FIFO channel and dual-port RAM channels is provided, the integration level of the motion control card is increased, and data classification transmission is achieved.

Description

Technical field

[0001] The invention relates to the technical field of mechanical design and its automation, in particular to a multi-axis motion control system and a control method thereof. Background technique

[0002] With the popularization of computers and the diversification of the industrial control field, open motion control cards have gradually become the mainstream control system of automation equipment. A typical open control system is realized by combining PCs and motion control cards. At present, in general-purpose motion control cards, the architecture based on DSP+FPGA is gradually mature. This architecture combines the advantages of DSP's high-speed floating-point arithmetic and FPGA's high-precision pulse control and flexibility to meet the control needs of various automation equipment . It mainly involves two directions of data flow, one is sent from the upper computer to the motion control card, and the other is sent from the motion control card to the upper c...
