The Remote Video Diagnosis System For CNC Machine

With the development of digital technology and computer technology, CNC machine were widely applied. When the machine broken down, the method of non-remote diagnosis may not be immediately diagnosed a CNC machine. The operating efficiency will be reduced, and resulting in great economic losses. Therefore, the research of a remote video-assisted diagnostic tool of CNC machine, based on networks and streaming, has important significance. The main function of this tool is the remote monitoring of the operating state and the alarm information of CNC system, for the staff real-time diagnose the CNC machine through the remote video and a small malfunction database. This paper developed a detailed remote video transmission and management program, successfully realized a video stream transmission between the machine and the client. Based on the above, we also proposed a method of fault diagnosis of CNC machine.The program and the method we used in this paper can realize a high-quality video data transmission between the machine and the client, while the video data has been commendably managed in the database, for the retrieval and analysis of the user in later stage.The main content of the work as follows:Firstly, been clear of the function of the remote video-assisted diagnostic system of CNC machine, developed a general scheme of the system, and selected the software and hardware of the system. The system includes three modules: the streaming media technology, the database management system and the fault diagnosis system of CNC machine.Secondly, we determined the general communication framework of the remote video-assisted diagnostic system of CNC machine, and the program of streaming protocols and video playback modes. Finally, we built a streaming media server and client by using the VLC open-source software, and realized the remote video monitoring of client.Thirdly, we set up a video file database, realized the classification, update, modification and retrieval of video files. Meanwhile, we proposed a method and idea of fault diagnosis of CNC machine, based on the malfunction database built in the video database.Fourth, design the human-computer interaction interface of the system, and applicate the video monitoring and fault diagnosis of the system.
