With the development of digitization of substation, the future trend of on-line monitoring system of substation power equipment is adopting the IEC61850 standard to realize seamless communication. However, the change of distance and node make synchronization precission of samples transmission become a problem. An implementation method based on the IEEE1588 standard is proposed, by use of DP83640 Ethernet...
The birth of remarkable advance in the development of computer and hardware in computer world has enables us to access information anytime and anywhere regardless of the geography factor. Therefore, replication in distributed system environment has become increasingly popular due to its high degree of availability, fault tolerance and enhance the performance of a system. Read-One-Write-All Monitoring...
Reliable communication is crucial for successful deployment of a wireless sensor network. Many environmental factors can affect the performance of radio links, and the deployment of a network without real-time information about link qualities can be a demanding task. This paper describes the CiNetView application that is intended to support the deployment and monitoring of wireless sensor network...
In order to protect pipeline transportation and prevent from manmade damages, it is very important to carry out such researches as prevention monitoring and accurate locating. Designed the system project of pipeline prevention monitoring, introduced its locating principle, the acoustic sensors and transducers are located at the end of each segment along the pipeline, as soon as damages appear in the...
With the development of ethernet technology, the requirement of time synchronization is becoming higher and higher on the distributed ethernet monitoring system. According to the requirement of bridge structure monitoring system, the distributed solution based on IEEE1588 protocol is presented after the research of IEEE1588 protocol and the explanation of principle on high precision synchronization...
Environmental monitoring is a critical process that demands accuracy, reliability and stability at the operation level. Monitoring variables such as temperature, humidity, barometric pressure, soil moisture and ambient light facilitates research in fields such as precision agriculture, habitat monitoring, weather monitoring etc. The use of wireless sensor networks (WSNs) provides a technology solution...
Most TV channels need to control its performance in live broadcasting. They need a way to help them make fast decisions and adjust their live programming in order to maintain high-level audience ratings. This article presents a real-time multi-channel monitoring web-based system. It integrates and synchronizes different technological environments from the data collection till the end-user software...
Control systems monitor and control production plants and manufacturing systems. Before they can be taken into operation, they have to be configured. To automate this process, which is called engineering, a standardized exchange format is required that forms the basis of the work of all those who are involved in the project and that is understood by anyone involved. In addition, the contents to be...
To study and gain a better understanding of the power system dynamics, the concept of building a frequency monitoring network (FNET) was proposed in 2000 [1] and has been realized in 2003. The FNET system consists of many high dynamic precision frequency and phasor estimation devices, also known as frequency disturbance recorders (FDR). These FDRs can be used at any 110 V or 220 V wall outlet and...
A major step in the evolution of Energy Management System (EMS) capabilities is towards improved presentation of real-time power system condition information (not just data) to the system operator; the primary purpose being to facilitate prompt identification and location of problem areas, and to expedite confident decision-making, in order to mitigate or obviate escalation of the problem at hand.
The paper presents a real-time vision system for automatic traffic monitoring based on a network of autonomous tracking units that capture and process images from one or more pre-calibrated cameras. The system, which has been developed within the framework of TRAVIS (TRAffic VISual monitoring) project, is flexible, scalable and can be useable for a broad field of applications, including traffic monitoring...
