Realization method of field bus, device management server and system

Abstract

The invention provides a realization method and system of a field bus as well as an equipment managing server. The method is applied to the equipment managing server; and the equipment managing server can establish communication connection with at least two sets of communication equipment. The method comprises the following steps of: after successfully establishing the communication connection, receiving self equipment information sent by the communication equipment through the equipment managing server; refreshing an equipment public network IP (Internet Protocol) address according to equipment managing information in the received equipment information; obtaining the equipment managing information of the communication equipment needing to be communicated with each set of communication equipment and determining the equipment public network IP address corresponding to the obtained equipment managing information; and sending the determined equipment public network IP address and the equipment managing information corresponding to the equipment public network IP address to the corresponding communication equipment. According to the realization method and system of the field bus as well as the equipment managing server, the problems that the field bus needs to the help of an Internet public network for networking, the Internet accessing cost of a fixed address is expensive and the application of a large amount of sensing and control equipment cannot be met are solved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a method for realizing a field bus, a device management server and a system. Background technique [0002] Fieldbus is a communication network used in process automation, manufacturing automation, building automation and other fields to realize the interconnection of field intelligent devices. As the basis of the factory digital communication network, the field bus communicates the connection between the production process site and control equipment and the higher control management level. Due to the special requirements for real-time and security, the field bus initially operates in the industrial dedicated LAN, which uses a definite address to realize data communication between devices and devices, and between devices and controllers. [0003] However, with the continuous expansion of the application field, the application range of the field bus has expanded from on...

Problems solved by technology

[0005] In view of this, the present invention provides a method for implementing a field bus, a device management server and a system to solve the problem of uncertain public network addresses in the prior art when the field bus is networked with the Internet public network to realize data communication. Internet access with a fixed address is relatively expensive and cannot meet the application problems of a large number of sensing and control devices. The technical solution is as follows:
