Industrial automatic real-time control device and method based on communication bus

Abstract

The invention relates to an industrial automatic real-time control device based on a communication bus. The industrial automatic real-time control device comprises an FPGA (Field Programmable Gata Array) chip, a driving chip and a physical layer chip, wherein the FPGA chip is connected with the physical layer chip through the driving chip; the physical layer chip is connected with a real-time communication bus; and the FPGA chip comprises a PCI-E (Peripheral Component Interconnect-E) bus interface, an embedded soft core module, a driving controller module, an FIFO (First In First Out) buffer module and a PCI-E data pack resolving module. The invention further relates to a method for implementing industrial automatic real-time control based on a communication bus by using the device. In the device and the method disclosed by the invention, the FPGA chip is adopted, so that appropriate resources can be selected flexibly according to user requirements in comparison to a DSP (Digital Signal Processor) chip in the prior art; meanwhile, the device and the method have the advantages of high expandability, high processing speed, high integration degree, easiness for updating and the like; the industrial automatic real-time control device based on the communication bus has a simple structure and low cost; and the method is easy and convenient to apply, and has a wide application range.

Description

technical field [0001] The present invention relates to the technical field of industrial automation control, in particular to the technical field of communication bus, and specifically refers to a communication bus-based industrial automation real-time control device and control method. Background technique [0002] The existing servo motor control is mainly based on the pulse control (Pulse) drive control system. In recent years, a digital control drive based on industrial Ethernet has emerged. Compared with the previous pulse control, RTEX (Realtime Express, real-time fast channel) has the advantages of low cost, high performance, simple design, high reliability, and easy expansion. Such as figure 1 Shown is a schematic diagram of the above two communication mechanisms. [0003] In addition, compared with conventional drives such as figure 2 The drive control system using Panasonic's A5N driver shown has good synchronization. The solution for the A5N driver provided b...
