Embodiment Construction

[0032] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0033] refer to figure 1 As shown, the Internet-based serial server system includes three parts of equipment:

[0034] (1) The remote device is connected to the industrial field device through the serial port on the device; the remote device integrates the XMPP protocol client and has the ability to communicate with the IM control terminal through the IM server.

[0035] (2) The IM control terminal, that is, the remote controller controls the platform; the IM control terminal also implements the XMPP protocol client. Through the authority management of the system program, the server address, account / password management, and port settings of the management remote device can be changed. Change management; while enabling communication with remote devices.

[0036] (3) The IM server is deployed on public Internet nodes, and coordinates and orga...

Abstract

The invention discloses a serial server system based on the Internet. The system comprises instant messaging (IM) servers, IM control ends and far-end devices, wherein IM is the English abbreviation of instant messaging, the IM servers are arranged on nodes of the public Internet and used for coordinately organizing the far-end devices to be communicated with the IM control ends and supporting an instant messaging protocol, the IM control ends are used for remote monitoring of the far-end devices, each far-end device comprises an IM client end and a serial port access module, the serial port access module is connected with industrial on-site devices through serial ports, the IM client end is accessed into the public Internet and supports the instant messaging protocol, and therefore communication between the IM client ends and the IM servers on the Internet nodes is achieved. Public Internet infrastructure construction is sufficiently utilized to achieve global remote control, moving control and the like, remote control efficiency is improved, and building comprehensive cost of a large-scale remote control system is lowered.

Description

technical field [0001] The invention belongs to the technical field of industrial control, in particular to an Internet-based serial port server system for industrial field control. Background technique [0002] Currently popular in the market is the use of serial servers to realize the implementation of transforming industrial field control with Ethernet. [0003] For ordinary serial servers, or serial-to-Ethernet devices, UDP or TCP is usually used for direct communication, and Web pages are used for device configuration. Such a serial port server has the following disadvantages: [0004] (1) The IP address of the device must be visible to the control terminal. If multiple devices are controlled, the Ethernet network topology is relatively limited. [0005] (2) If it is required to use the public Internet for remote control, the IP address of the device is required to be a public network IP address. Since the public network IP address is a scarce resource, this implement...
