利用zigbee 無線感測尋找美食街座位
Using zigbee wireless sensor for indoor locating in food court
摘要
在本篇論文中，我們設計一個手機的應用程式然後我們運用在百貨公司的美食廣場上。而我們設計的這個應用程式可以幫助人很有效地在美食廣場中找尋到空的座位。而我們是使用ZigBee無線網路來幫助我們定位使用者的位置，還可以傳送美食廣場的資訊到我們的智慧型手機中。 首先我們先介紹一個室內定位的新的應用程式然後運用到我們的美食廣場中，我們建立了一個資料庫來儲存美食廣場中的空位資料來以便使用者可以利用該應用程式來查詢找到座位的位置。接著我們利用ZigBee無線感測器透過三角測量使用者的位置。該方法是使用最靠近使用者的三個感測器來定位使用者的位置。然後資料庫就可以通過ZigBee無線感測器網路來傳遞美食廣場的資訊與資料。最後我們使用應用程式知道哪個座位是空的，使用者就可以輕鬆的選擇自己的座位。然後所有的資料都將顯示在世慧型手機上。 在本篇論文的研究結果貢獻如下： 1.便利性 在上下班的高峰期，人們可以使用該應用程式很容易地找到空座位不需要花費更多的時間在尋找座位。 2.效率性 它可以減少時間準確地找到空的座位，使人們能夠順利地吃上的們餐點。 3.加快經濟增長 此應用程式將增加購物的效率，此外增加人們的流動，然後增加美食廣場的收入。

In this thesis, we design a new application on smart phones for food courts. This application is able to efficiently and accurately find empty seats in food courts. And we use Zigbee Wireless Network to locate user's position, it can transport food court information to user's smart phones. First of all, we introduce a new application for indoor locating in food courts. We build a data base to save the information for seat plan of food courts so that users can use the application to find the seat position. Second, we use Zigbee Wireless Sensor to locate user’s position by Triangulation Method. This method uses the nearest three Zigbee sensors to locate the user’s position. Based on the signal’s strength between a user and the nearest three sensors, the information will help us to locate the user’s position. Third, the database can transport the food courts information to user's smart phones by using Zigbee wireless sensor network. Finally, we use the application to know which seat is empty that user can easily to choose their seat. Then all the information will display on the smart phones. In this thesis, we have some contributions as follows: 1. Convenience During the rush hour, people can use the application to easily find empty seats without spending much more time on looking for empty seats. 2. Efficiency It can reduce the time to accurately find the empty seat so that people can enjoy their meat smoothly. 3. Accelerate economic growth: This application will increase the shopping efficiency. Also, it increase the rate of people’s flow and then increase the food courts revenue.
