Remote machine maintenance system through Internet and mobile communication

Machine condition monitoring is important to factory efficiency and safety of workers. A variety of vibration signals analysis techniques have long been used to diagnosis machine status. Based on the newest Internet and mobile communication technology we developed a remote fault diagnostic system with many merits. This remote monitoring system takes XML as a core and uses it to encode diagnostic data. The utilization of XML gives this system many advantages including minimum research work on the client side, and simplicity to expand the system. This system publishes the diagnosis data not only by WEB, but also by WAP. Then users can check the machine status including data, image and video, through the Internet and mobile terminals. The automatic alarm part, which is developed based on Microsoft's Smartphone 2003 operating system, can actively send alerting messages to the engineers' mobile phones and call these phones to make sure they get an alert when the machine's status is abnormal. © Springer-Verlag London Limited 2007.
