Example Embodiment

[0028] The present invention will be further described below in conjunction with the drawings and embodiments:

[0029] Figure 1 is the structural block diagram of the distributed measurement and control system, which includes an industrial control bus network 1, a monitoring computer 2, and a number of measurement and control nodes 3. The monitoring computer 2 and the measurement and control node 3 have their own processors and network interfaces, and the measurement and control nodes 3-1, 3-2, 3-3, etc. also contain specific measurement and control modules. The data between the monitoring computer 2 and the measurement and control node 3 is exchanged in XML format. In order to improve the reliability of the network, multiple bus networks 1 or multiple monitoring computers 2 can be set up, which are mutual backups.

[0030]In order to realize real-time monitoring and management of the measurement and control node 3 that is dynamically connected or removed, the basic program flow ...

Abstract

The distributed network plug-and-play detecting and monitoring system includes a, industrial bus network, supervisory computer, and some nodes. It can dynamic find out the accessing or removing of node for real-time monitor. Wherein, the computer and node all has self CPU module and network interface module, the latter can access different detection module according to task. It uses XML format to exchange data between computer and node. This invention improves system extensibility, and saves assembly and maintenance cost.

Description

technical field [0001] The invention relates to a distributed networked measurement and control system, in particular to a plug-and-play method and device for a distributed networked measurement and control system based on an extensible logo language, belonging to the field of computer measurement and control. Background technique [0002] In recent years, the Internet, which incorporates computer technology and network communication technology, has developed rapidly. At the same time, the development of software technology based on network applications has also brought a profound impact on the development of other fields of technology. Especially in the field of measurement and control, the measurement and control technology is developing in the direction of networking, which makes the measurement and control system further transform into a distributed and open architecture. Measurement and control systems are widely used in remote data acquisition, process control systems,...
