Passive acoustic recording has great potential for monitoring soniferous endangered and cryptic species. However, this approach requires analysis of long duration environmental acoustic recordings that span months or years. There is a variety of approaches to analysing acoustic data. However, it is unclear which approaches are best suited for monitoring of endangered species in the wild. Specifically,...
Monitoring system has become one of the most important means for perimeter intrusion prevention. But most of existing monitoring systems are passive surveillance. In this paper, we propose a method to implement active perimeter intrusion detection by identifying human targets in video images captured by monitoring system. In order to enhance the robustness of detecting postures of human targets, this...
This paper presents a novel security monitoring system of mine based on power line communication; with networking and routing technology, an artificial cobweb routing of security monitoring communication system is established to ensure the reliability of data communication in the system, and improve the reliability and validity of the PLC-based security monitoring system. This paper describes in detail...
Corrosion monitoring is a persistent problem relating to materials degradation. Modern plants have a need to predict and measure materials degradation due to corrosion during early stages and preferably on-line. So an overview of on-line electrochemical corrosion monitoring techniques is provided. The methods used in this study were: linear polarization resistance (LPR), electrochemical impedance...
The battery energy storage system can provide flexible energy management solutions that can improve the power quality of renewable-energy hybrid power generation systems. This paper firstly introduced the integration and monitoring technologies of large-scale lithium-ion battery energy storage station (BESS) demonstrating in SGCC national wind/PV/BESS and trans. demonstration project in Zhangbei,...
One kind of good drought monitoring technology (DMT) can help to detect and characterize drought conditions, and reduce adverse drought impacts. We evaluate how a DMT for China, based on a land surface model, would perform. The land surface model current soil moisture, runoff and evaporation. The DMT incorporates the Palmer drought severity index (PDSI) and soil moisture deciles taken from the LSM...
In order to overcome the defect of physic-chemical monitoring system and enhance the intelligence of biological monitoring technology, an online monitoring system of fish behavior is proposed in this paper. The main contributions of this system are as follows: 1) adaptive background updating algorithm (ABU); 2) automatic camshift tracking algorithm (ACT) with twice searching; 3) particle filter tracking...
Advanced Metering Infrastructure (AMI) enables smart grids to involve power consumers in the business process of power generation, transmission, distribution and consumption. However, the participant of consumers challenges the current power systems with system integration and cooperation and security issues. In this paper, we introduce a service-oriented approach to AMI aiming at solving the intercommunication...
This paper analyzed current and future needs of monitoring the ship power system, the network characteristics of industrial Ethernet and Zigbee, and put forward a hybrid network of them for monitoring the ship power system. Moreover, according to protocol structure of Zigbee, this paper demonstrated direct and indirect implementations of the gateway between industrial Ethernet to Zigbee, and implemented...

But recently, by using novel techniques and materials, knitted fabric has broadened its application in medical field. In this study, some knitted fabrics were produced by using conductive fibers, and the relationship between the electrical property and the extension of conductive...
The clustering algorithms for wireless sensor networks might differ depending on the application and network architecture. Not all clustering algorithms are suitable for wireless indoor monitoring system. In this article, we summarize the features of wireless indoor monitoring system, analyze the clustering algorithms for wireless sensor networks, and provide a clustering algorithm based on K-means...
This article puts forward a method to access the data and analyzed results from the monitoring system of environment based on WSN with the B/S mode. It resolves the problem of low speed of page refresh with Ajax. The experiment shows that the partial refresh feature of Ajax can make it possible for the users to get access to the data and analyzed results easily through the browser, and experience...
ZigBee offers a practical application solution coupled with low rate, low cost, low energy consumption characteristics for WSNs. There are many ZigBee monitoring systems which have been developed based on ZigBee. Energy consumption and latency are two critical performance measurements in most monitoring systems. The design of routing strategy in network layer may affect these two performance measurements...
This paper presents a design of wireless network system based on Zigbee for monitoring the formaldehyde level. The system consists of coordinator, router and sensor nodes, in which signals are mainly controlled, transmitted and received by Chipcon's leading SoC chip CC2430. The communication in the network is realized by Texas Instruments' Z-stack, which is compatible with Zigbee specification. Compared...
