In order to accelerate smart grid development and promote distribution automation technology for large area application, aiming at the problems of operational difficulties and poor share about data existing in current C/S structure of distribution automation terminal, a design of distribution automation terminal based on 3 layer B/S schema embedded web server is put forward by researching and analyzing...
In view of the existing virtual experimental teaching software is primarily demonstration, the lack of the people of the interactive system, the lack of authenticity in the process of simulation experiment teaching. In this paper, the development of 3 d virtual teaching laboratory based on virtools platform, in the process of chemistry teaching experiment, for example, and describes the development...
Oil level is one of the important monitoring parameters of Power Transformer, it is important to detect the oil level when it is too low or too high in time and take the appropriate measures to ensure the safe of power transformers. To be effective and accurate detection of oil level, this paper processed infrared image of the oil conservator with the improved Watershed segmentation algorithm, take...
A high accident potential exists at high-speed signalized intersections where an area close to an intersection, called a dilemma zone (also known as decision zone). The potentially negative impact of dilemma zones on the operational capacity and safety of signalized intersections, has motivated a great deal of effort to the mitigation of the dilemma zone issue. This mitigation system have been pursued...
This paper analyzes the time, lane and direction distribution characteristics of volume and speed, based on data survey, aimed at the section on urban arterial street near the school in Huhhot. The research results show that there is a peak traffic which begins school close time and continues 15 minutes at noon. Near the primary school, the main factors causing traffic congestion are parking on driveway,...
The main purpose of this paper is to present a method for determining yellow time based on dilemma zone concept. The results of comparative analysis show that estimated yellow times obtained from the model proposed in this paper are much different from actual yellow times obtained from the field. Combining with the dynamic characteristics of motor engineering, calculation is provided on the vehicles'...
In this paper, a novel grey rough set model for interval-valued grey sets information systems named interval-valued grey-rough set model is proposed and the basic theory and propositions of the interval-valued grey-rough sets is studied. Based on the proposed interval-valued rough grey model, rough similarity degree is defined, and the clustering of the interval-valued grey information systems is...
This paper firstly combines the relevant knowledge of grey correlation analysis and interval deviation degree. Considering the reference sequence and the comparison sequences containing grey numbers, this paper gives a grey correlation analysis method based on the interval deviation degree, and its effectiveness is proved by an example.
To find the defects of the apparatus in a substation in the early stage, an infrared temperature measurement based monitoring system is established. An infrared-visible hybrid detector consists of an uncooled infrared focal plane array detector and a visible light camera, the lenses of both are of the same specification. As a result, the graphs are exactly matched. The hybrid detector is implanted...
