Around the key elements, the construct scheme and cooperative mechanism among experts of VDC are designed. According to the diagnosed object, the context knowledge of a fault machine, fault cases and ActiveX-based analysis tools are integrated into a multimedia consultation environment in VDC to enhance the efficiency of expert consultation. Simultaneously, the technique of push subscription in a SQL Server is utilized to collect machine condition data in an enter- prise machine condition database, which ensures the security of the database. The VDC system in Xi'an Jiaotong University has been applied to remote diagnosis of a blower in Wuhan Iron and Steel Corporation and the system construction reasonableness and the running stability are verified.展开更多

An opened and modularized data share framework integrated with virtual graphic transportation is presented to realize the data exchange. As a result, it implements a real-time monitoring, diagnosis and maintenance system based on WWW. An effective support technique for the real-time remote fault diagnosis, maintenance and entire life cycle design of products is supplied.展开更多

Via the Internet a remote monitoring and diagnosis system can be established. In this paper, the model of an Internet based remote monitoring and diagnosis system is presented; the function of every part of the RMD system is discussed. Then, we introduce a practical example of a remote monitoring and diagnosis system that we established in a factory; its traits and functions are described.展开更多

Therefore, it has received a great dea l recognition from academia and the industry. The IRD technology, which is based upon database, computer, and network technologies is the focus of correlative r esearch all over the world. Although some scientific institutions have developed primary IRD systems, their functions are quite narrow with many shortcomings. I n short, the standard of remote diagnosis has not been created, in particula r the network manufacture and diagnostic resources cannot be shared extensiv ely, so the systemic open character has not been developed enough to create the efficiency and the scope of the existing remote diagnostic systems. Aimed at improving the limitations mentioned above, in this paper we try to develop Web -CORBA open remote diagnosis architecture over the Internet, which is based on the existing troubleshooting software. We have designed and realized the general -purpose data interface of the software and some Java applets functional module s. Thereby the software’s open character and application field get widened. Our current research is focused on building the remote intelligent diagnosis center on the basis of the Web-CORBA architecture. Some basic functions have been app lied. Further, we put forward the project of combining the enterprise interior d iagnostic system to the remote diagnosis center, and make a study of building th e remote diagnosis object network architecture. The open remote diagnostic syste m based on Internet offers many advantages. Also, with the CORBA distributed obj ect technology, the distributed diagnostic resources can be connected as a coope rative diagnosis object system, in order that all the resources can be shared to the full extent, and the advanced diagnostic technique can be applied as soon a s possible. This is the inevitable trend of the diagnostic technology.展开更多

Vast amount of data and information flow from the aquaponics plant itself with its huge amount of smart sensors for water quality, fish and plant growth, system state etc. and from the stakeholder, e.g., farmers, retailers and end consumers. The intelligent management of aquaponics is only possible if this data and information are managed and used in an intelligent way. Therefore, the main focus of this paper is to introduce an intelligent information management (IIM) for aquaponics. It will be shown how the information can be used to create services such as predictive analytics, system optimization and anomaly detection to improve the aquaponics system. The results show that the system enabled full traceability and transparency in the aquaponics processes (customers can follow what is going on at the farm), reduced water and energy use and increased revenue through early fault detection. In this, paper the information management approach will be introduced and the key benefits of the digitized aquaponics system will be given.展开更多
