With the rapid development of WSN technology and the improvement of people's living standard, the intelligent home environment and security requirements are also increasing. This paper proposes a smart home system design based on Wi-Fi wireless sensor network and describes respectively from the design of Wi-Fi network, the node hardware design, the software design functional processes. The design...
Based on the reviewing of the wireless sensor network (WSN) research and application, the disadvantages of the traditional cable sensing data acquisition system are pointed out, and a new energy-saving, cheap and wide application scope system by Wireless RF way is proposed. This paper gives out a method of wireless sensor data acquisition system based on nRF905, including the design of structure,...
This paper describes a process developed by TRW Conekt for capturing and reviewing end-user requirements when developing complex systems such as wireless sensor networks (WSNs). An example is the WiTNESSS project, where the process helps to define common system architectures for WSNs to cover several different aircraft applications.
The need of real-time data acquisition in industry control system is growing, ARM7 processor LPC2200 combined with embedded real-time operating system μc/OS-II realize the data acquisition system and remote transmission through the wireless communication and can be used in a wider field. The overall structure of the system, the software process and acquisition hardware circuit are introduced. The...
In order to solve the problems of hydrographic measurement, a new river flow velocity monitoring system is presented in this paper. The system hardware design is discussed in detail. Data acquisition module based on accelerator MMA7260Q, wireless communication module based on wireless chip and MCU peripheral circuit module are mainly discussed. Communication quality of hardware system is improved...
Wireless Sensor Network is an emerging technology which can significantly reduce the cost and the time needed to monitor the conditions of civil structures. This work presents W-TREMORS, a new wireless sensing system for high-frequency distributed data acquisition. Our sensor network is based on the low-power and low-data rate standard IEEE 802.15.4, and we used inexpensive hardware. Nevertheless,...
Remote environmental monitoring often has the characteristics of monitoring points widely distributed, large numbers, long distance, individual collection points in remote areas, etc. In the past, the manner of remote environmental monitoring data acquisition that staff operate in person on the spot is extremely inconvenient. In order to solve the problems produced in the manner above, we design the...
