內容簡介
物聯網是國家新興戰略產業中信息產業發展的核心領域,將在國民經濟發展中發揮重要作用。目前,物聯網是全球研究的熱點問題,國內外都把它的發展提到了國家級的戰略高度,稱之為繼計算機、網際網路之後世界信息產業的第三次浪潮。新技術發展需要大批專業技術人才。為適應國家戰略性新興產業發展的需要,加大信息網路高級專門人才的培養力度,許多高職院校利用已有的基礎和教學條件,設定物聯網相關技術專業,或修訂人才培養計畫,推進課程體系、教學內容、教學方法的改革和創新,以滿足新興產業發展對物聯網技術人才的迫切需求。為適應電氣信息類相關專業的教學需要,編者編寫了這本書。
物聯網是通過各種信息感測設備及系統(
感測網、
射頻識別系統、紅外感應器、
雷射掃描器等)、條碼與二維碼、全球定位系統,按約定的通信協定,將物與物、人與物聯接起來,通過各種接入網、網際網路進行信息交換,以實現智慧型化識別、定位、跟蹤、監控和管理的一種信息網路。物聯網的主要特徵是每一個物件都可以定址,每一個物件都可以控制,每一個物件都可以通信。顯然,它作為“感知、傳輸、套用”3項技術相結合的一種產物,是一種全新的信息獲取和處理技術。因此,本書將緊緊圍繞物聯網中技術架構物聯網技術的知識體系,分為物聯網概述、感知技術、通信技術、物聯網套用技術及安全共6章內容。
雖然本書的出發點是一種概括性的導論,但並不希望因此而使讀者遠離物聯網前沿問題的深入研究和全面學習。鑒於這一考慮,本書對每類問題的討論都試圖達到一定的深度和廣度,並在章末附有簡明扼要的小結以及一定數量的習題。這些學習建議旨在為讀者進一步開闊視野提供一些幫助,習題與章節內容密切相關,以幫助讀者鞏固和複習有關概念。
本書在編寫過程中得到了相關領導、老師、同學的支持和幫助。在此,向所有為本書的出版做出貢獻的人們表示衷心感謝!
鑒於編者水平有限,書中難免存在疏漏和不足,懇請廣大讀者批評指正。
