Web-based remote monitoring and fault diagnosis system

This paper proposes an approved Web-based multilayer distributed software architecture solution for remote monitoring and fault diagnosis. To tightly integrate legacy monitor systems, a component framework model based on COM has been proposed, which is very suitable for remote monitoring and fault diagnosis applications. This system has the potential for exchanging a data acquisition system by using wrapper service components. A mixed thick Web client architecture is proposed to implement real-time remote monitoring. A Web-based remote monitoring and fault diagnosis system is developed by using modeling technology, Web application technology, component technology and VME extension for instrumentation (VXI) bus technology, which publishes a fault diagnosis algorithm package, a basic monitoring package and an advanced analysis package on the Internet. This system provides authorized users with an effective and instant way to access new monitoring and diagnosis component packages in time. This paper gives researchers a paradigm to accomplish similar systems. The technique developed may be used for other fields, such as power engineering, manufacture and transportation system.     

Manufacturing e-quality through integrated web-enabled computer vision and robotics

This paper investigates the development of a Web-based quality control system with the use of Internet-based computer machine vision. Such a system allows designers located far from the production facility to monitor, control, and program the quality inspection process as the product design evolves. Quality control tasks are performed and monitored remotely through the Web where Internet-based machine vision sensors inspect part dimensions and tolerance while Internet-enabled robots perform the necessary robotic operations. The remote quality monitoring system—which lets the user monitor the part status including data, image, and video through the Internet—is built using Java. The use of Java allows for interconnection and data transfer between the different components of the Web-based quality system and the robots. The ability to access and control quality control devices via the Web benefits the current manufacturing environment in the following ways: ubiquitous access to the production floor, remote control/programming/monitoring capability, and integration of production equipment into information networks for improving efficiency and product quality.     

Lightweight monitoring and control system for coal mine safety using REST style

The complex environment of a coal mine requires the underground environment, devices and miners to be constantly monitored to ensure safe coal production. However, existing coal mines do not meet these coverage requirements because blind spots occur when using a wired network. In this paper, we develop a Web-based, lightweight remote monitoring and control platform using a wireless sensor network (WSN) with the REST style to collect temperature, humidity and methane concentration data in a coal mine using sensor nodes. This platform also collects information on personnel positions inside the mine. We implement a RESTful application programming interface (API) that provides access to underground sensors and instruments through the Web such that underground coal mine physical devices can be easily interfaced to remote monitoring and control applications. We also implement three different scenarios for Web-based, lightweight remote monitoring and control of coal mine safety and measure and analyze the system performance. Finally, we present the conclusions from this study and discuss future work.

Remote sensing, diagnosis and collaborative maintenance with Web-enabled virtual instruments and mini-servers

Optimised maintenance can reduce operating costs by demanding less resources and avoiding equipment breakdown, hence ensuring that daily manufacturing and production will not be interrupted. Web-based maintenance is one of the most efficient methods for optimising maintenance. The Web-based maintenance system that we have developed uses virtual instruments, to provide remote sensing, monitoring, and on-line fault diagnosis for equipment, together with a collaborative maintenance platform for international experts to interactively share their experiences in maintenance. Moreover, Web-based maintenance is suitable for multi-tasking and multi-user types of industrial work environments. In this paper, we summarise the methods used for Web-based remote sensing and monitoring, the design and implementation of Web-enabled virtual instruments, the architecture of the collaborative maintenance platform, and the design for the mini-servers. Each mini-server is equipped with a conventional mini-Web-server and a data acquisition (DAQ) server. With the help of Web-based maintenance, local companies can be transformed into global companies providing services to their customers anywhere and at anytime.

On optical design limitations of generalized two-mirror remote beam delivery laser systems: the case of remote welding

Remote welding opens new possibilities for the highly productive and qualitative joining of metal structures, especially in the automotive industry. This work first summarises the different types of remote welding systems (RWSs) based primarily on the different features of the laser beam scanning systems that RWSs implement. A generalised two-mirror scanning system is geometrically analyzed in order to evaluate the irradiated laser intensity on the workpiece as it changes due to the inclinations with which the laser beam impinges to the processing plane. The study discusses the limitations that a two-mirror scanning system enforces in remote welding, and sets the foundation for further theoretical and experimental investigation of this process.
