摘要
无线传感技术是新一代的传感技术,具有非常广泛的应用前景,其发展和应用将会给人类的生活和生产的各个领域带来深远影响。
本文提出了一种基于Si1000无线片上系统的无线传感系统的设计方法。在对无线通信技术及相关检测技术进行研究的基础上,选取了适用的温度、湿度及气压传感器,设计了传感信号的调理电路,可实现对现场环境信息的检测;设计基于Si1000的单片机应用系统,可实现检测信号的采集、就地显示及通过无线方式将处理后的信息向上位接收节点发送的功能;并在LabView软件平台上进行了上位机软件设计,可以实现对送回的信息的有效接收、处理和显示。文中对以上设计方法及实现过程进行了详细描述。
实验证明,系统可以在100m范围内实现对现场检测信息的有效采集,具有较高的可靠性和稳定性;而且通过增加节点数量并引入EZMAC通信协议,可以在节点间搭建无线传感网络。本文提出的设计方法具有一定的应用推广价值,对其他关于无线传感的设计具有一定的参考价值。

Abstract
Wireless sensor technology is a new generation of sensor technology,it has a very wide range of applications,which development and application will have a profound impact in all areas of human life and production.
This paper presents a wireless sensor system based on the Si1000 wireless chip system design method. Selected on the basis of research on munication technology and related detection techniques, the application of temperature, humidity and pressure sensors, sensor signal conditioning circuit is designed, can achieve the detection of the field of environmental information; design Si1000-based microcontroller applications the system can detect signal acquisition, local display and processing information bit up the receiving node to send wirelessly; and LabView software platform, PC software design can be achieved on the information returned effectively receiving, processing and display. A detailed description of the above design and implementation process.
Experiments show that the system can be effectively collected on-site inspection information within a 100m range, high reliability and stability; and by increasing the number of nodes and the introduction of munication protocols, wireless works can be set up between nodes. This paper presents the design method has certain application value, and other wireless sensor design has a certain reference value.
