Zigbee無線感測網路在圖書館導覽搜尋應用
An Application to Library Guiding System and Path Planning by Zigbee Wireless Sensor Network
摘要
在本文中，我們提出了基於Zigbee無線感測網路的圖書館導引系統。我們的系統可以提高找尋書籍的效率和避免迷路發生。 本文可以分成四個部分。第一部分，我們將建立一個數據庫來保存的所有書籍的資訊，以便使用者可以使用手機連接網頁，通過指導，找到圖書的位置。第二部分，該系統將使用Zigbee 無線感測網路來定位使用者位置，我們利用圓交點定位法，利用最靠近使用者的節點並根據每個節點到使用者的訊號強弱來定位出使用者的位置。第三部分是要求使用者輸入他們要搜索的圖書清單。根據使用者的書籍列表中，我們從資料庫中找到書籍位置，並通過A*srarch algorithm計算路徑。通過使用A*srarch algorithm，系統計算使用者和每個目標之間的距離，然後選擇使用者最近的路徑。當使用者要到下一個目標時，系統將刪除以前的位置。最後一部分，我們將顯示該系統的實驗結果。 在本文中，我們有一些貢獻如下： 1.創新的方法：它提供新的圖書館尋書服務方式。從書架中編號的標牌傳統的指導不同的是，新的服務允許使用者將書籍名稱輸入到一個網頁，並顯示最短的路線，立即在網頁上顯示正確的位置。 2.方便性：無線感測網路上使用我們的圖書館導向系統提供使用者快速了解圖書館的相關位置及自己所在位置並提供快速的路徑規劃，指引使用者快速的尋找到自己所要的圖書資料，提升圖書館對使用者的服務品質。

In this thesis, we propose a library guiding system with path planning based on Zigbee wireless sensor network (ZWSN). Our system can improve the efficiency of finding books and avoiding occurrence of getting lost. This thesis can be divided into four parts. Un the first part , we will build a database to save the information of all books so that the users can use the phone link web page to discover books position by guidance. Un the second part , the system will use ZWSN to locate user’s position by circle intersection point. This method delects the nearest zigbee sensors to user , and according to the signal’s strength between user and the nearest sensors, the to help us to locate the user’s position. The third part is to ask the user to type the books list they want to search. According to the user's books list, we find the suggested books position from database and calculate the path for every user by using A*srarch algorithm. By using A*srarch algorithm, the system calculates the distance between user and every target then choose the nearest path for user. When user arrives the next target, the system will delete the previous position and calculate one more time until all targets have been passed. Un the last part , we will show the simulation results of this system. In this thesis, we have some contributions as follows: 1. Innovative approaches: It provides a new book locating service in a library. Different from traditional guidance with numbered signs among book shelves, the new service allows a reader to type in books into a web page and will show a map with shortest routes to the correct locations of these books immediately on the web page. 2. Convenience: The use of our library guiding system on zigbee wireless sensor network not only provides the best direction for helping the readers of a library to easily access the materials as they want, but also promotes the service quality of the library.
