摘要 無線傳感器網(wǎng)絡(luò)被譽(yù)為21世紀(jì)四大高新技術(shù)之一，同傳統(tǒng)有線傳感器網(wǎng)絡(luò)相比，它具有架構(gòu)方便，靈活性高，成本低等特點(diǎn)，在工業(yè)、農(nóng)業(yè)、環(huán)境、軍事等領(lǐng)域具有廣泛的應(yīng)用前景。無線傳感器網(wǎng)絡(luò)是由分布在監(jiān)測(cè)區(qū)域內(nèi)大量的價(jià)格低廉的微型傳感器節(jié)點(diǎn)，通過無線通信方式形成的一個(gè)多跳自組織網(wǎng)絡(luò)，對(duì)其的研究不僅具有較高的理論價(jià)值，而且具有重要的應(yīng)用價(jià)值。目前監(jiān)測(cè)設(shè)備中使用有線方式采集傳感器數(shù)據(jù)，存在安裝、維護(hù)困難、成本高等問題?；诖?，本文針對(duì)水環(huán)境監(jiān)測(cè)系統(tǒng)的特點(diǎn)，提出一種無線傳感方法，來實(shí)現(xiàn)水參數(shù)的監(jiān)測(cè)。
本文首先介紹了無線傳感器網(wǎng)絡(luò)的特點(diǎn)和應(yīng)用，及其研究現(xiàn)狀和發(fā)展前景。然后，根據(jù)面向水環(huán)境無線傳感監(jiān)測(cè)的要求，分析系統(tǒng)設(shè)計(jì)的目標(biāo)和功能，提出了系統(tǒng)的總體設(shè)計(jì)方案和系統(tǒng)結(jié)構(gòu)。設(shè)計(jì)了基于CC2430芯片的硬件開發(fā)平臺(tái)，詳細(xì)地描述了硬件平臺(tái)各個(gè)功能塊的結(jié)構(gòu)、功能和原理，最后對(duì)整個(gè)系統(tǒng)的性能進(jìn)行了測(cè)試。本文設(shè)計(jì)的監(jiān)測(cè)系統(tǒng)以無線傳感器網(wǎng)絡(luò)技術(shù)為核心，增強(qiáng)了系統(tǒng)的靈活性，可維護(hù)性和可擴(kuò)展性。節(jié)點(diǎn)與Android通過GPRS模塊進(jìn)行通信，較好的實(shí)現(xiàn)對(duì)水參數(shù)的監(jiān)測(cè)。
無線傳感器網(wǎng)絡(luò)技術(shù)是傳感器技術(shù)，無線通信技術(shù)和計(jì)算機(jī)技術(shù)的融和，隨著科學(xué)技術(shù)的發(fā)展進(jìn)步，會(huì)不斷的完善與突破，也勢(shì)必促進(jìn)基于該技術(shù)的應(yīng)用獲得巨大的發(fā)展。

Multi-parameter detection instrument based on wireless sensor network
Abstract Wireless sensor network is regarded as one of the twenty-first Century four new and high technology. Compared with traditional wired sensor network, it is convenient, high flexibility, low cost, and has wide application prospect in the industrial, agricultural, environmental, military and other fields. Wireless sensor network is a large number of cheap micro sensor nodes distributed in the monitoring area, through wireless communication to form a multi hop ad-hoc network, not only has a high theoretical value for their research, but also has important application value. NOW sensor data acquisition use the wired monitoring equipment, installation, maintenance difficulties ,and the cost is high. Based on this, this paper according to the characteristics of water environment monitoring system, proposes a wireless sensing method to achieve the monitor of water parameters.
This paper first introduces the characteristics and applications of wireless sensor networks, research situation and development prospect. Then, according to the wireless monitoring requirements of water environment, we analyse the system design goal and the function, and puts forward the overall design plan and system structure system. The design of hardware development platform based on CC2430 chip, describes in detail the structure, function and principle of the hardware platform of each function block, and finally we test the performance of the whole system. The monitoring system designed in this paper using wireless sensor network technology as the core, enhance the system flexibility, maintainability and scalability. Node communicate with Android through the GPRS communication module, and the monitoring of water parameters is well.
Wireless sensor network is a integration of sensor technology, wireless communication technology and computer technology. With the development of science and technology, it will improve and break constantly, and it will promote the great development and application based on this technology .
Keywords: Wireless sensor network, CC2430, Android mobile phone client , GPRS
