Design Of Cnc Machine Tool Store Instant Communication Fault Diagnosis System

This article from the CNC machine maintenance work and vocational education remote field teaching need, starting with a knife as little depot repair, explore a remote maintenance assist PMC, maintenance on-site audio and video data network instant communication system design.Knife library on the nc machine system occupies an important position, is also the most easily CNC machine parts of the failure, for the sword library and reliable operation, guarantee the stability of system, isolate faults and fault occurs, prevent to reach this goal, in systems installed cameras and adapters, and real-time Internet communication module, the whole line of nc equipment and machine tools data monitoring system, composed upper constitutes a site maintenance personnel, machine data and remote fault diagnosis expert instant messaging system, realize the good efficient machine maintenance management.In research tool store type automatically change tool device PMC control process, based on the remote maintenance workshop nc machine tools to assist needs, will achieve machine maintenance of network monitor, put forward "network monitoring layer and site monitoring layer" two layers structure to bus structure as the system network topology structure, with the field of industrial Ethernet technology to the scene network design for. Using Web browsing and utilities Internet network realization of CNC remote data transmission, realize CNC machine tool store remote maintenance assistance.Papers focusing on CNC machine tool store instant communication fault diagnosis system solutions and video collection schemes are studied, and on this basis on design. This paper puts forward that the knife library type automatically change tool device PMC data acquisition and network transmission system structure, and these hardware design, so as to realize the PMC data network transmission. In dao depot repair process, sometimes need to watch video, sometimes knife library action should be stopped a picture, by higher clarity observation of a state. Then achieve instant messaging remote maintenance assistance systems acquisition transmission video and audio,realizing scene with a remote assist site data mutual preach on design. Finish the clarity of higher picture gathering and transmission,video transmission through technology and related technical analysis, through the use of VFW API library function realization of video collection, using control embedded web design process and the programming of the remote transmission based on web video. Reuse DirectShow audio technology, proposed the instant video real-time communication system, the design of the real-time data acquisition of audio and video transmission, coding, software module design. Finally application industrial Ethernet will field numerical control equipment connect,video data through the Internet network will be uploaded to remote assist points,thus achieved a video monitoring and fault to diagnose function.
