According to the study of the quantitative analysis on the major hazards of the entity and virtual body in the mine production system, the early warning method of the mine safety production with the mixed-mode of the active and passive way is presented based on wireless sensor networks. In which, applying the ZigBee2007/PRO protocol stack, wireless sensor microcontroller technology and the GIS positioning...
In this paper, a new wireless sensor network (WSN) for large electrical equipment on-line monitoring is proposed, designed and implemented. The design of the wireless monitoring system emphasizes to solve the problems of traditional wired on-line monitoring system wiring too much, cost too high, fault diagnosing and maintaining difficulty and so on. The hardware design for wireless sensor network...
The design of wireless sensor network applications is an emerging area of research. The volume of data collected by a sensor network of any type can be overwhelming and the associated challenges of application processing and presentation are significant. The design of a wireless network sensor information and identification system (WiNS Id) database which archives the data reported by distributed...
In wireless sensor network, the sensors collect data about natural phenomenon and transmit them to a server in real-time. Many researches mainly focus on processing continuous queries as approximate forms. However, these approaches are difficult to apply to such environmental applications which require storing the correct data. In this paper, we introduce two insertion methods, called TSI (time-segment...
In this paper we develop a Web-based monitoring system which collects various kinds of environment information inside a building in real-time and monitors those in real-time by establishing a sensor network inside the building. To realize this system, this paper, we use Micaz mote sensor node which is equipped ATMega128L to use for measuring various kinds of environment data values and a sensor node's...
