A real-time database-based hart field device management method and system

Abstract

Disclosed is an HART field equipment management method and system based on a real-time database. The method comprises that an industrial operation station sends valid data corresponding to HART commands to a control station in a message mode in the industrial Ethernet protocol; the control station transmits the unpacked valid data in a message mode in the CAN (controller area network) protocol; an HART module unpacks the received CAN protocol messages and transmits the valid data in an HART command mode; HART equipment feeds response information back to the HART module after receiving the HART commands, and the HART module unpacks the response information and packs and transmits the response information in the message mode of the CAN protocol to the control station; the control station unpacks the CAN protocol messages and packs and sends the response information to the industrial operation station in the message mode of the industrial Ethernet protocol. The HART field equipment management method based on the real-time database helps send all the HART field equipment data to the operation station in a master-control room, enables a user to conveniently and remotely check, modify and configure configuration information of the field equipment just in the control room, improves the equipment maintaining efficiency and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of HART communication, in particular to a real-time database-based HART field device management method and system. Background technique [0002] CAN (Controller Area Network), which belongs to the category of field bus, is a serial communication network that effectively supports distributed control systems. It was developed by Bosch in Germany in the 1980s for the automotive industry. communication bus. Because of its high performance, high reliability and unique design, people pay more and more attention to it, and it is widely used in many fields. And any errors that occur can be detected. When the signal transmission distance reaches 10km, CAN can still provide a data transmission rate up to 50kbit / s. Because the CAN bus has high real-time performance and application range, it can be arbitrarily matched from a high-speed network with a bit rate up to 1Mbps to a low-cost multi-line 50Kbps network. Ther...

AI Technical Summary

Problems solved by technology

The staff in the main control room cannot understand the actual situation of the HART field equipment, and cannot perform equipment management and parameter configuration operations on it.

The traditional on-site inspection method is time-consuming and labor-intensive, and the operating status of HART field equipment cannot be well known, which increases the probability of production failure
