One of the biggest problems of today's internet technologies is cyber attacks. In this paper whether DDoS attacks will be determined by deep packet inspection. Initially packets are captured by listening of network traffic. Packet filtering was achieved at desired number and type. These packets are recorded to database to be analyzed, daily values and average values are compared by known attack patterns...
Water resources monitoring has been widely used in river section, water source, groundwater, water function, social users using water, drain and sewage treatment plants, and so on. Water resources automatic monitoring and analysis technology can be divided into three aspects: data collection and analysis, data transmission, and data application and management. The application and management of water...
Publish-Subscribe Services have been widely employed in distributed Real-Time applications. However, the standard technologies and model which provide the foundation for Publish-Subscribe Services do not address issues such as fault tolerance and dependability of services. Aiming to supply this gap, this paper describes Quality of Service (QoS) policies and provides concrete strategies and methodologies...
Real-time Dynamics Monitoring System(RDMS) is applicable to monitor the dynamic behaviors of large region grid, such as low-frequency oscillation, short-circuit, frequency fluctuation, etc. For the perturbation in power systems occurs incidentally, it's difficult to collect enough cases for an complete test on RDMS, which may lead to potential risks of outage. So it's necessary to study more efficient...
The authors introduced the development and conception of data warehouse and database and research the relationship between database and data warehouse, and have studied the difference between their technology. At last discuss the combination and application of the database,and date warehouse technology.
This article proposes an agent-based real-time monitoring system for large scale peer-to-peer video streaming platforms which provides traffic, user receiving quality and system information through web-based presentation. The information is useful for helping service providers to assess the system performance as well as the quality of the streaming service. The monitored information is also stored...
Collecting and analyzing real-time data of a distributed wireless sensor network system is very challenging since it combines a series of processes to continuously monitor and respond to a wide variety of events. This paper presents an event-driven, real-time data collection system architecture for an independent living spaces monitoring system. A service-replacement-based timestamp matching structure...
In recent years, disastrous earthquake assault the human frequently. The evaluation and estimate of the loss and damage in seismic disaster is an important factor for earthquake emergence and post-earthquake reconstruction decision-making. This paper synthetically designs a set of disaster real-time evaluation system based on the seismic networking of things. This paper firstly collects real-time...
This paper used middleware technology, using the network as the carrier of information, integrated the three-layers C/S software structure model into the manageable multi-layer software architecture, and used this architecture to construct a communication network real-time monitoring system that has good real-time performance, stability, and scalability.
Nowadays, to avoid over-speed and parking violation, repair vehicles are commonly monitored and positioned under monitoring and dispatching system by most of local-level power supply enterprises. With the development of electric utilities, power supply enterprises are urged to improve their response speed to power troubles. In such a situation, electrical repair vehicles must be under a status of...
The thesis introduces the overall structure of the electric power monitoring system. In ord to solve slow speed and poor real-time of the current system, the thesis focuses on designing the real-time database of the power monitoring system and implements the real-time database of SCADA by referencing to the ideas of Hibernate, and then completes the design.
Functions and features of configuration software are introduced. They are discussed in details the design project, function and realization of real-time monitoring water supply system in configuration software and the result is given. The project has been in use in water supply system of Xi'an Xianyang International Airport. It indicates by operation that the design project is practical and stable.
By this paper, the background for the occurrence of the industrial control configuration software(CS) is analyzed, the connotation of CS is given, the architecture of it is constructed, and the current situation of CS is summarized. Finally, the six development trends of CS are predicted, they are: function customization, function extension, application expansion, monitor networking, software standardization...
This paper mainly deals with the data exchange by DDE technology between the higher engine system and site equipment. The system reads the data to Excel with realtime reports, or stores data to Access database, then generates history reports in flexible way with different inquire conditions. The role of communications protocol in monitoring and other applications is briefly introduced. By using VB...
A robust medical monitoring device should be able to provide intelligent diagnosis based on accurate analysis of physiological parameters in real-time. At the same time, such device must be able to adapt to the characteristics of a specific patient and desired diagnostic needs, and continue to operate even in presence of unexpected artifacts and accidental errors. A reconfigurable architecture is...
This paper presents the results of collaborative research from the SUPERGEN FlexNet Consortium into Wide Area Monitoring, Protection and Control (WAMPAC). The focus of the research addresses the design and development of an optimal WAMPAC architecture, communication infrastructure and real-time WAMPAC applications which will play an important role in future GB power network operation and understanding...
Electrical utilities, stretched between requests for higher quality and lower costs are operating their assets at or close to their ratings, very often beyond their design life and with minimum maintenance. Keeping grid reliability at reasonable levels in these conditions is indeed a technical challenge, that can be won getting the most comprehensive information about assets that are of critical importance...
This paper presents an online monitoring system for operator situation awareness using real-time synchrophasor measurements developed under a DOE R&D and demonstration project. The system provides wide area power system visualization, near real-time event replay and early warning of potential stability problems. The technologies implemented in this system include the memory residence object oriented...
This paper introduces the design plan of a distributed control and management system for power devices, and puts emphasis on the hardware composition and working principle of the system. The system is divided into two parts: field devices and monitoring center. The former uses ARM to collect data and control MC35, a module of GPRS; the later uses Browser/Server to realize centralized management of...
This paper proposes to use a water detection methodology based on a colorimetric approach to develop a near real time system allowing to monitor and to detect anomalies at a fine time resolution and in a systematic way The algorithm was calibrated over Africa using daily reflectance MODIS data from 2003 to 2011. The proposed approach has 3 major outputs updatable in near real time: (1) a permanent...
