Gateway communication module based on ARM and FPGA, and DCS control system

Abstract

The invention provides a gateway communication module based on ARM and FPGA, and a DCS control system, and the module comprises two connected gateway communication units which are respectively used asa main gateway communication unit and a slave gateway communication unit. The gateway communication unit comprises an FPGA unit and an ARM unit. The FPGA unit is connected with the ARM unit through abus; the FPGA unit comprises an FPGA processor, and an RS-485 communication interface, a 10M / 100M self-adaptive Internet access, a Profibus field bus interface and an RAM which are connected with theFPGA processor; the ARM unit comprises an ARM single-chip microcomputer, and an RS-485 communication interface, an RS-232 serial port, a GPRS interface, a VGA display interface, an HART communicationinterface, a CAN interface, a FLASH and an SDRAM which are connected with the ARM single-chip microcomputer. The ARM single chip microcomputer comprises a 10M / 100M / 1000M self-adaptive internet access. According to the gateway communication module based on the ARM and the FPGA and the DCS control system based on the ARM and the FPGA, the effectiveness, the stability and the expandability of the gateway communication module are achieved based on the redundancy configuration architecture of the ARM and the FPGA.

Description

technical field [0001] The invention relates to a gateway communication module, in particular to a gateway communication module and a DCS control system based on ARM and FPGA. Background technique [0002] Distributed Control System (DCS), also known as distributed control system, is a new type of computer control system relative to centralized control system. It is developed and evolved on the basis of centralized control system. of. DCS is a multi-level computer system composed of process control level and process monitoring level with communication network as the link. It integrates 4C technologies such as computer, communication, display and control. Its basic idea is decentralized control, centralized operation, hierarchical management, Flexible configuration and easy configuration. [0003] With the rapid development of the "Industry 4.0" intelligent manufacturing concept and the integration of information technology and communication technology, the DCS control syst...

AI Technical Summary

Problems solved by technology

First of all, with the accelerated development of the "Industry 4.0" intelligent manufacturing concept, fieldbus technology is widely used. The above-mentioned gateway architecture cannot completely cover fieldbus technology, showing poor adaptability and scalability.

Secondly, as the power, petrochemical and other industries have higher and higher requirements for safe production, higher requirements are put forward for redundant communication buses, big data information transmission and storage. The above gateway architecture has no redundant bus configuration, which cannot meet the requirements for safe production. Demanding industry application requirements
