Abstract

In this paper, the structure and relative function of virtual remote diagnosis system of printing equipment was presented. Its network structure is based on 3G, which is advanced wireless network technology at present. Visiting internal data of Programmable Logic Controller (PLC) which controls the printing equipment is the way to get parameters of equipment. Driving virtual prototype is in order to simulate work in real time. Analyzing these parameters via experience database which was designed reasonably and logically is in order to maintain the equipmentand detect themal function timely by the virtual remote diagnosis system.
