無線傳感網(wǎng)絡(luò)的概念 無線傳感網(wǎng)絡(luò) [1]（ Wireless Sensor Network）簡稱 WSN，它是由大量靜止 或者移動的傳感器節(jié)點(diǎn)有組織的分布在一定區(qū)域而構(gòu)成的無線網(wǎng)絡(luò)，其目的是協(xié)作感知、采集、處理和傳輸網(wǎng)絡(luò)所覆蓋區(qū)域內(nèi)對象的監(jiān)測信息，并報(bào)告給用戶。 USB protocol。 后臺系統(tǒng)的任務(wù)主要是 分析判斷從 前臺系統(tǒng) 接收 的信息， 達(dá)到實(shí)時(shí)監(jiān)測前臺區(qū)域 各種參數(shù) 的目的 ， 無線傳感網(wǎng)絡(luò) 一般應(yīng)用于監(jiān)測生物棲息環(huán)境和工業(yè)生產(chǎn)控制過程中的溫度、濕度、噪音和各種化學(xué)成分濃度等 參數(shù)。 本科畢業(yè) 設(shè)計(jì) 題 目

杭州電子科技大學(xué)本科畢業(yè)設(shè)計(jì) ABSTRACT With the development of the work and wireless munication technology, people had started to constantly apply them to practical production and life, the Wireless Sensor Network is one of the good application examples. It mainly consists of the front desk system and background system. The front desk system is just like a embedded system, which contains a lot of sensors, control and wireless munication module, they are distributed in certain areas to acquire signal ,store data and forward information ,also they can municate with each other. The main task of the background system is the analysis and judgement of the information received from the front desk system, to achieve the purpose of realtime monitoring the area parameters, the Wireless Sensor Network generally used in monitoring the temperature, humidity, noise and various chemical position concentration parameters of biological habitats and industrial production process. This paper is mainly research the realization of the front embedded system in the Wireless Sensor Network and simply introduced the relevant contents of the wireless munication module, also specially discussed the implementation of signal acquisition and information process. It mainly included hardware and software ponents. Hardware has all kinds of sensors, such as the sound listener, USB cameras and TQ2440 development board, software is the key point which includes boot loader, Linux kernel, the file system and the whole cross development environment based on Qtopia, the most important is the development of appl
