Development of a Transmission Power based Platform for Wireless Sensor Network Positioning Systems
|摘要:||近年來無線通訊與嵌入式系統技術快速的提升，造就了無線感測網路(Wireless Sensor Network，WSN)蓬勃發展，定位即是無線感測網路的重要應用之一。定位系統已經廣泛應用於工程、醫療、交通與個人行動服務等民生用途，其中全自動駕駛車是目前很熱門的研究之一。因此，本論文之研究目的為建構一無線感測網路導引系統平臺，透過IEEE 802.15.4協定來實現無線感測網路技術，並以德州儀器(Texas Instruments，TI)生產、擁有內嵌Transceiver的CC2530控制器做為系統核心晶片，提出基於傳輸功率調變之定位機制，並設計一套車輛路徑導引演算法，進行移動方向的決策，使車輛自行抵達目標位置。|
With the rapid evolutions of wireless communications and embedded systems technology, wireless sensor network has developed swiftly. Location system, one of the important applications of wireless sensor networks, is widely used in engineering, medical, traffic and personal positioning. Currently Autonomous vehicle is one of the very popular researches. The major goal of this study is to develop wireless sensor network guidance systems which materialize wireless sensor network technique via the IEEE 802.15.4 communication protocol. The core chip of designed system is named for CC2530 controller which has embedded Transceiver and is produced by Texas Instruments. The proposed method for distance measurement is based on transmission power adjustment. The study designs vehicle guidance control laws, and the systems can control the forward direction of the vehicle by the laws which are designed. Finally, the vehicle can arrive at the setting target.
