【摘要】 无线传感器网络是一种新型的信息获取和处理技术，综合了基于微电子的传感器技术、分布式信息处理技术和无线通信技术，广泛应用于工业控制中信号数据的采集与回收分析。在无线传感器网络数据传输中，目前主要利用蓝牙、Wifi、GPRS等等技术实现，这些技术存在或是速率低、距离近、传输安全性不高等问题。针对这一问题，本文提出一种传输速率较快、传输距离大。传输安全性较高的基于无线传感网络的通用无线传输系统，该方案具有的通用性，不但可以用于军用、商用，而且可以在民用中推广，不仅对国防建设有重要作用，在社会经济生活中的意义也相当重要，有着较为宽广的前景与战略意义。根据系统设计的功能指标与技术指标，硬件上设计了了一种由一个主控站与多个从控站，由上位机同一控制管理的具有时间统一、同步技术的无线传输技术系统。软件实现了无线传输协议，设计了一种具有控制系统功能的上位机软件，。利用此系统的整体设计，进行了一次对于图像回读与无线传输的实验，对实验结果进行了分析。实验结果表明，系统实现了远程距离在1000m之内，传输速率最大在369Kbps的功能，基本符合设计要求。更多还原

【Abstract】 Wireless sensor networks are a new type of information acquisition and processingtechnologies, integrated sensor based microelectronics technologies, distributed informationprocessing technology and wireless communication technologies. It is widely used in signaldata acquisition and analysis of recovery in industrial control. Data transmission in wirelesssensor networks, now realized with Bluetooth, Wifi, GPRS and so on technology,thesetechnology is characterized by low speed, short distance,or low transport security. In responseto this issue, this paper presents a universal wireless transmission system based on wirelesssensor networkswith faster transmission rate，longer distance，high transport security. Becauseof the universality of the programme, the system can not only be used for military,commercialbut promotion in the civil, and it has an important role not only for the construction ofnational defense, but it’s a very important significance in social and economic life.and has amore broad prospects and strategic significance.Depending on functional specifications and technical specifications of the system design,hardware design consists of one master station and more from the control station, controlledby the host computer to the same management with time to unify, synchronize technology forwireless transmission systems. Software enables wireless transfer protocol, and designes a PCsoftware to control system. The overall design of the system, an image back reading andwireless transmission experiments was completed , and analyzed the experimental results.Experimental results show that the system enables remote distance within 1000m, transfer ratemaximum in 369Kbps, which meets the design requirements.更多还原
