Industrial field equipment remote diagnosis maintenance system and method

Abstract

The invention discloses an industrial field equipment remote diagnosis maintenance system and method. In the system, an engineer station is connected with a remote bridging server via an internet. The remote bridging server is connected with a general mobile terminal via a wireless network. The general mobile terminal is connected with field equipment via a USB cable. Communication connection between the engineer station and the general mobile terminal is established by the remote bridging server via an ID number and an encryption key of the remote mobile terminal. Diagnosis maintenance is performed on the field equipment by the engineer station via sending commands like diagnosis and supervision. Remote diagnosis maintenance of industrial equipment is realized by effectively utilizing wireless networks like 2G / 3G / 4G / wifi and the general mobile terminal like a mobile phone and a tablet computer so that implementation cost is low and generality is high. Meanwhile, frequent business travel of engineers is avoided, fault processing time of the field equipment is shortened, and timeliness of field equipment maintenance is enhanced.

Description

technical field [0001] The invention relates to a system and method for remote diagnosis and maintenance of industrial field equipment, which is particularly suitable for various industrial field equipment using remote diagnosis and maintenance, and can effectively improve the timeliness of field equipment diagnosis and maintenance. Background technique [0002] Product maintenance is an important task for equipment suppliers, whose products are distributed all over the country and even all over the world. Once there are quality or parameter setting problems on site, engineers need to go to the site to deal with the problems, which brings a lot of manpower and material resources as well as the time consumption. Some equipment suppliers also provide methods for diagnosis and maintenance using wireless networks, but there are the following deficiencies: [0003] (1) The remote diagnosis only has the data monitoring function, and cannot perform parameter modification and confi...

Problems solved by technology

[0003] (1) Remote diagnosis only has data monitoring function, and cannot perform parameter modification and configuration download online

That is, the data can only be returned from the site to the service center, but the service center cannot control and operate the on-site equipment for online debugging. If there is a parameter setting error, professionals need to go to the site to adjust the parameters. The function is single and the maintenance cost is high;

[0004] (2) In order to realize remote diagnosis, the field equipment is often equipped with a special communication module for the equipment. The project implementation cost is high, and the failure of the field equipment is often random, so it is not necessary to carry out the diagnostic connection of the field equipment all the time.

[0005] (3) The remote diagnosis method is not universal, different products require different diagnostic software and systems, and the development and maintenance costs are high
