Remote monitored maintenance method and system based on 3G and cloud computing technology

Abstract

The invention discloses a remote monitored maintenance method and system based on 3G and a cloud computing technology, which belong to 3GInternet network remote monitored maintenance in the industrial automation industry. Field data and video signals of control systems such as a programmable logic controller (PLC), a programmable automation controller (PAC), a human-machine interface (HMI), a frequency converter, a host computer and the like of a remote cloud field station are acquired in real time by using a 3G Internet network and a cloud server platform, so that practical difficulties in remote online diagnosis, debugging, online program modification and program uploading and downloading in an enterprise are eliminated, wireless monitored maintenance of the remote cloud field station is realized, and field attention of a field operating engineer is not required. The remote monitored maintenance system can be applied to any place covered by the 3G network, is operated very conveniently and flexibly, is easy for remote management, debugging and maintenance, and has the characteristics of online instantaneity, safety, high speed, easiness in operation and introduction and the like.

Description

Technical field [0001] The technical field to which the present invention belongs is 3G Internet network remote monitoring and maintenance in the industrial automation industry, and specifically relates to a method and system for remote monitoring and maintenance based on 3G and cloud computing technology. Background technique [0002] At present, most of the domestic applications of 3G networks and cloud computing methods are still used in civilian applications, such as wireless transmission of 3G mobile phones, 3G video, and 3G audio. Compared with 3G and 2G, the main advantage is the increase in speed. For industrial occasions, the remote programmable controller PLC downloads programming. At present, more low-speed modem telephone lines are used. The remote wireless data collection basically uses GPRS to temporarily solve some problems, but these two The acquisition speed of the method is all at the Kbps level, and the speed is low. It is still unable to solve the requirements...

AI Technical Summary

Problems solved by technology

In industrial occasions, the remote programmable controller PLC uploads and downloads programming. At present, more low-speed Modem telephone lines are used. Remote wireless data acquisition basically uses GPRS to temporarily solve some problems, but these two The acquisition speed of the method is at the Kbps level, and the speed is relatively low. It still cannot meet the requirements of modern industrial automation control and network management, such as remote real-time diagnosis of equipment, online debugging, report feedback, and on-site real-time video. signal etc.
