A remote monitoring or maintenance method and device

Abstract

This invention relates to a method for remote monitor or maintenance and a device for realizing it, in which, a remote monitor or maintenance working station is connected with an agent connected with an object needing remote monitor or maintenance via network, and the agent first of all monitors the communication state of the object and then transmits the monitor result to the working station to decide if it needs to access the object, after the agent sets up a virtual channel for the connection requirement of the station, it manages the channel safely by setting a timer with fixed time interval and sets up a transparent transmission path between the station and the object.

Description

technical field

[0001] The invention relates to a remote monitoring or maintenance method and a device for realizing the method. Background technique

[0002] At present, as the geographical scope covered by the industrial automation system and the number of sites at each level are increasing, more and more equipment objects need to be monitored or maintained remotely. In order to obtain the fault information of the equipment object that needs to be monitored or maintained and analyze the cause of the failure in time, the maintenance personnel usually need to run the maintenance software developed by the manufacturer for the specific equipment on the PC, and communicate with the equipment object that needs to be monitored or maintained through serial communication. Connect to obtain relevant fault information and analyze the cause of the fault. On the one hand, since most of the intelligent industrial equipment that needs to be monitored or maintained does not have a dedica...
