Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] The idea of ​​the invention is to realize the remote transfer of the OPC data interface through the OPC technology conforming to the industrial standard and the Internet network technology, that is, to transfer the OPC interface on site to the remote service center. The whole system can be integrated with the distributed FF field bus supporting OPC interface, and can also be integrated with the German Siemens PROFIBUS bus to realize remote monitoring of field devices without affecting the original field monitoring. details as follows:

[0050] Such as figure 1 As shown, it includes on-site control center, running on-site main control system and on-site OPC data server, providing OPC interface of on-site data to the upper monitoring system; it also includes on-site workstation and remote service center, of which: in the on-site control center, on-site ...

Abstract

The system includes a field working station and a remote service center. The field working station runs the OPC data collection module and the network data releasing module conforming to TCP/IP protocol by using the OPC data collection and network data releasing application program, and is connected to the field control center through OPC interface. The remote service center runs the network terminal module conforming to TCP/IP protocol, the remote OPC server module and the remote control module supporting OPC interface by using network terminal application program and the remote OPC service application program. The network communication terminal module receives the field data released by the network data releasing module, and then releases the received data to the remote OPC service module by which the data is transmitted to the remote monitoring module.

Description

technical field [0001] The invention relates to the fields of industrial automation control and remote monitoring. Specifically, it is a remote configuration monitoring system conforming to the OPC (ObjectLinking and Embedding for Process Control) standard. The system achieves remote connection with the computer on the remote network through the means of Internet network communication, and realizes the remote transfer of the standard OPC data interface. At the same time, the configuration software technology is used to complete the remote monitoring and monitoring of the equipment, which is the pre-diagnosis of the final equipment. and maintenance and troubleshooting. Background technique [0002] In the remote monitoring of the existing technology, there are already various remote monitoring and fault diagnosis systems for large-scale rotating machinery abroad, but our country has just started in this regard. For example, gas turbines in some large enterprises in Shenyang...
