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.
The paper is start from the characteristics of ground subsidence on the Daye Iron Mine, analyzes the instability of the surface area caused by the subsidence of Iron Mine. The ground subsidence can be divided into the fall area and the crack area. On this basis, a new thinking is proposed, which is getting the monitor data of the fall area and the crack area changes, then building monitor model. And...
A simple and fast algorithm for tracking multiple targets in real-time traffic scene is presented. The connected domains of moving objects, which are segmented out by the adaptive background subtraction algorithm, are obtained by morphological operation and resolution reduction. Then the track-association algorithm is applied to track the targets. The experimental results show that the proposed method...
At present, water quality monitoring is the essential part to our country's aquaculture. In this paper, we developed a real-time water quality environment monitoring system based on wireless sensor network to acquire data of environmental factors of water quality. Also, the system can provide expert knowledge to deal with data for making control decision. Such a system is attractive because it ensures...
Aiming at the issue of slow operating speed, low real-time character and unsuitability on looking for the source of the harmonic which is the traditional power quality monitor system based on single chip Microprocessor (SCM), this paper designs a new one based on DSP. Analyzing from the hardware and software designed, it present the principle of clamp type Hall sensor and adopts the improved fast...
The rate at which we speak has a bearing on its comprehensibility and is important in recent times with mushrooming call center operations. An optimal speaking rate is one that is neither too fast not it is too slow. A fast spoken speech makes conversation unintelligible while a slower speaking rate speech makes the conversation boring. Speaking rate definitely varies depending on the emotional state...
Nowadays, many influential security-related facts are reported multiple times by different sources and in different languages. Therefore, in the recent years, the research on advancing event extraction technology shifted from classical single-document extraction toward cross-document information aggregation and fact validation. However, relatively little work has been reported on cross-lingual information...
To point of environmental data monitored and dispersed, the transported data character are real-time and continued, we have been used the telecommunication network, which has been covering the whole country and city, main including PSIN (public switch telecommunication network) and DDN (digital data network) and GSM (global system for mobile communication), the monitoring system of regional environmental...
To solve the problems of poor stability and real-time capability of the current substation RTU monitoring system, the RTU monitoring system based on GPRS and PLC was designed. PLC has the characteristics of powerful function, easy operation and strong reliability, so its application can cover almost all areas of industrial control. In order to know all the equipments' realtime running and alarm information...
In order to realize the real-time state data monitor of the electromechanical actuator(EMA), the EMA and other subsystem establish a ground half physical experiment simulation platform based on the CAN bus. The CANoe software decodes the received EMA CAN data and showes the result in the image window. The decoding data contains the EMA current, motor operation state, EMA angle and etc. Through these...

The overall structure of the system, the software process and acquisition hardware circuit are introduced. The...
The system is a new on-line monitor system. Which is consisted of a master station, which is a computer with intelligent CAN-bus interface unit, and a slave station, which is a monitor module for battery parameter measure. The paper introduced the hardware at first, which composed of the CPU circuit, the canbus interface, and then, focus on the software design, including the automatic monitoring of...
In dynamic environments, interactivities with smart objects can be complex for accomplishing particular activities or procedures. Ideally, interaction paradigms for smart objects should naturally adhere to the ethos of ubiquitous computing; however, it hasn't been fully achieved yet due to the lack of general and intuitive mechanisms in dealing with heterogeneous objects. The major challenges of assuring...
This article describes our experience from the implementation of PRISM in the Castalia simulator. PRISM is a recently-proposed protocol for real-time monitoring in single-hop and multi-hop wireless sensor networks. The protocol allows to define the maximum number of nodes, the requirements on the network synchronization and the data-rate in a flexible manner, in order to accommodate for different...
In order to meet the current water resource management automation and remote monitoring needs, a GPRS-based real-time management system is designed, which includes terminal subsystem, master station subsystem and communication service subsystem. The terminal subsystem is developed based on STM32F103X microprocessor and GPRS network. The GPRS module of MC55 is used to realize the remote wireless data...
Based on analyzing the advantages and disadvantages of several system models in BAM, established in the dynamic sense, cooperative work and real-time data processing of BAM system, this paper will employ an event-driven architecture and propose an event-based and service-oriented business activity monitoring system model. This model is constructed in the form of buses on the pre-existing various information...
Geant4 for Mission Radiation Effects Simulation (G4MRES) is a prototype tool with near real-time capabilities to nowcast radiation exposure levels for operational spacecrafts. G4MRES combines space weather real-time data from on-board radiation monitors together with Geant4 Monte-Carlo particle propagation, and supplies mission operators and space engineers with valuable information about the space...
This paper presents a novel approach for designing the portable wireless ECG monitoring terminal for use in mobile application in a personal healthcare scenario. For portable application purposes, an ultra-low power 16-bit micro controller acts as the core unit of the terminal. The ECG signal measurement module, storage module and Bluetooth wireless communication module are assembled to construct...
This paper introduces an adaptive test method to dynamically control test flow and test contents with continuous per die updates of test fail rates. The method employs Bayesian statistics to model a separate fail rate for each test. Test reordering and elimination is based on statistics of these predicted fail rates and is naturally monitored by a wafer based reset. Wafer sort test response data for...
