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.     

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.

Automated vision inspection in network-based production environment

This paper presents a new, holistic, Internet-based quality control approach. In recent years, a rapidly changing business environment driven by fierce international and domestic competitions has pushed companies to focus more on quality issues. A new strategy in quality control better suited to information-integrated production environments is a natural byproduct. The new strategy is called EQM, short for e-quality for manufacture, which allows designers located away from the production facilities to monitor, control, and program the quality inspection processes as the product design evolves. EQM also allows the quality data to be integrated within the company’s information network for automated quality monitoring and control functions. Such integration relieves the human operators from laborious, error-prone, and boring tasks of quality monitoring and samplings practices, which will help reduce production costs and lower the chance of shipping defective products to the customers.

Design and implementation of Web-based diagnosis and management system for an FMS

Given the rise in competition within the global marketplace, the paradigm for manufacturing has changed dramatically. While downstream activities have become the focal point for global competitors, manufacturing remains at the root of a firm’s competitive edge. To remain competitive, firms are progressively shifting their manufacturing operations to overseas markets. Foreign markets offer a host of advantages to manufacturers but one of the obvious key advantages is cheaper labor. Even in industries where the required labor-to-capital input ratio is relatively low within the production process, lower labor costs allow the production of more competitively priced products. The emergence of this paradigm, however, has led to a number of managerial problems. Operating a manufacturing facility overseas creates difficulties for management both in the area of personnel and resource allocation. In this project we developed a Web-based remote control platform using digital cameras, a PLC controller and a PC-based Visual Basic human-machine interface (HMI) to create a flexible manufacturing system (FMS). An FMS can be easily controlled and monitored through an Internet-based PLC-control system using a PC-based HMI platform. From remote locations, this platform enables management to effectively monitor, control and diagnose a manufacturing process via the Internet.

A web-based advisory system for process and material selection in concurrent product design for a manufacturing environment

This paper reports the work of selecting suitable manufacturing processes and materials in concurrent design for manufacturing environment. In the paper, a fuzzy knowledge-based decision support method is proposed for multi-criteria decision-making in evaluating and selecting possible manufacturing process/material combinations in terms of the total production cost. Based on the proposed method, a prototype Web-based knowledge-intensive manufacturing consulting service system (WebMCSS) with the client-knowledge server architecture is developed to help designers/users find good processes and materials while still at the conceptual level of design. The system, as one of the important parts of an advanced design for manufacturing tool, is a concept level process and material selection tool that can be used as both a standalone application and a Java applet freely available via the Web. Interlinked with Web pages of tutorials, and reference pages explaining the facets, fabrication processes and material choices, the system performs reasoning and calculations using the process capability and material property data from the remote Web-based database and knowledge base that can be maintained and updated via the Internet. The use of the system is illustrated with an example.
