For real-time environmental monitoring of air quality to design the system, use the virtual instrument test software LabVIEW to achieve real-time monitoring of pollutant gases, With database access toolkit to access Access database for LabSQL, display the Real time monitoring data and trends, Environmental monitoring personnel Customized monitoring time and data storage time based on actual conditions,...
In this paper, flight faults are generated and visual aircraft instruments are created as well as real-time information communication between simulation flight data and virtual instruments is established. Particularly, dynamical faults generation and its corresponding display system are developed and simulated in detail. Finally, the system is validated for authenticity and reliability by taking the...
The status of the remote monitor system is introduced and the composing and the principle of implement of the system are presented. Based on it, the function and the characteristic and each of modules of software and database design are introduced too. The system improves the performance and stability of supply power and reduces the times of power cut, it can forecast the possible fault through analyze...
ARP spoofing is a deception within the LAN caused by ARP protocol flaws, which could cause the whole network paralyzed and even worse users' important information stolen through spoofing. The features of ARP is introduced in detail, the update mechanism of ARP mapping table is summarized by ARP spoofing simulation experiment, and the process of ARP spoofing is analyzed. An effective solution which...
Intrusion detection technology has developed over more than 30 years from the host-based to network-based and has become the indispensable security technology of information systems. On the basis of the study of the existing intrusion detection systems, this paper reviews the history of intrusion detection technology, and sum up the recent hot-spot problems researched. Then, six technical difficulties...
This paper designed a fully functional Automation Dispatching Operation System of Power Network, while Multi-Agent theory is applied and the MAS model is constructed. On the basis of this model, this paper researches the corresponding inference-machine, which can adapt to complexity of the net-topology, the diversity of the operation task and the flexibility of operation mode. Through the coordination...
Recently The electronic weighing apparatus has been applied more and more in data processing and process control. The traveling overhead crane has been widely applied in metallurgy and freight transportation. Now, the measure for the load of Traveling overhead crane mostly adopts mechanical load safety device or simply electronic weighing device. But in its actual application, there must be some problems...
The modern intelligent parking management system is a combination of various functions of subsystems. In order to solve the deficiency of artificial management on efficiency, security, performance and management in the traditional parking lot, this article designs a relatively independent vehicle positioning subsystem by constructing a ZigBee wireless network, using wireless sensors to capture vehicle...
This paper presents a method of structured road lane detection for blind travel aid; Median Filter is implemented to process image firstly, then mark off the region of interesting in the initial image, Canny edge enhancement, threshold is used to segment the image, road lane is fitted by modified Hough Transformation. Finally, according to the detected region to judge whether racing course of bind...
In order to obtain the mechanical characteristics of high voltage circute breakers, an embedded microprocessor is properly used in the monitroing device, that is described in the paper. The mechanical characteristics of high voltage circuit breakers are monitored through long-term recording the signal during the operation. The data recorded are utilized for diagnoseing fault and may be employed in...
“Sent the correct data to the right place in the right time” is the basic requirement of battlefield data distribution system. The increase of widely distributed combat nodes leads to an increased information exchanges between them which can have very different requirements for data exchange; these nodes are developed with different architecture, programming language or operating systems, which leads...
