This article designs a rescue-assist wireless sensor networks for fire rescue and health care in large building. This system consists of wearable tags, route sensor nodes and base station. The wearable tag detects the activity of the user. We firstly propose an efficient fall detection algorithm. This algorithm has a low computational complexity and can be used in sensor node. And the wearable tag...
In order to collect energy monitoring data of large-scale public buildings, a data/image transmission device based on embedded TCP/IP protocol is designed and made in this paper. This device was designed with STM32 chips, receiving data or original images from meter reading device wirelessly, and transferring the data and images to monitoring center with TCP/IP protocol through the existing Internet...
To monitor the energy consumption of large public buildings, it is proposed to research a data transmission device on ZigBee-embedded development - TCP / IP is proposed. ZigBee can achieve accurate data and real-time transmission. This paper makes the new data protocol for data transmission and also describes the system focused on realization of hardware and software. The device can realize telecommunication...
A portable information terminal(PIT) is designed and implemented for building disaster rescuing application. Based on MIPS processor Au1200, the hardware architecture and peripheral extension is expounded in details. Then the communication interfaces including ZigBee and MMS are designed respectively to acquire field information and exchange data with remote center. Based on Windows CE, the system...
Nowadays, Wireless Monitoring for home security is among the cutting-edge researches in the field of International Intelligent Building. To implement real-time surveillance of the home security, the intelligent remote monitoring system was developed for home security based on ZigBee technology and GSM / GPRS network. The system can send abnormal images and warning messages through MMS and SMS, receive...
