1、摘要ZigBee技術(shù)是最近幾年發(fā)展起來的低復(fù)雜度、低功耗、低數(shù)據(jù)速率、低成本、易應(yīng)用的近距離雙向無線通信技術(shù)，可應(yīng)用于工業(yè)控制、醫(yī)療監(jiān)護(hù)、交通監(jiān)管、智能家居等場(chǎng)合。無線傳感器網(wǎng)絡(luò)就是由部署在監(jiān)測(cè)區(qū)內(nèi)的大量微型傳感器節(jié)點(diǎn)通過無線電通信形成的一個(gè)多跳的自組織網(wǎng)絡(luò)系統(tǒng)，其目的是協(xié)作感知、采集和處理網(wǎng)絡(luò)覆蓋區(qū)域里被監(jiān)測(cè)對(duì)象的信息，并發(fā)送給觀察者。本文主要介紹基于ZigBee技術(shù)的無線傳感器網(wǎng)絡(luò)技術(shù)應(yīng)用于橋梁檢測(cè)系統(tǒng)。該系統(tǒng)是在列車按正常速度通過橋梁時(shí)，在不會(huì)使行車和設(shè)備增加任何限制條件的情況下，對(duì)橋梁的動(dòng)載性能進(jìn)行監(jiān)測(cè)的便攜式儀器

3、采集站或筆記本電腦，進(jìn)行時(shí)域分析和頻域分析，最終給出橋梁結(jié)構(gòu)變化的判定和橫向剛度指標(biāo)的判定，從而有效地保證了橋梁監(jiān)測(cè)的實(shí)時(shí)性和準(zhǔn)確性。關(guān)鍵詞：ZigBee；無線傳感器網(wǎng)絡(luò)技術(shù)；檢測(cè)系統(tǒng)AbstractZigBeeisakindoflow—complexity,lowpowerconsumption，low-data-rate，low-cost，easilyappliedshort-rangewirelesscommunicationtechnology．ItcanbeusedinIndustrialControl，Medi
