【摘要】：旅游业在我国经济中占据的地位逐渐重要。目前很多企业和机构推出了旅游相关的移动应用系统,这些应用系统围绕旅游的出行规划、票务等进行了研究和推广应用,但是这些应用实现的景区内导游导览功能形式单一,缺乏个性化和主动性。为了提升景区的吸引力并增强游客在游览时的自主性,本文设计和实现了基于室内无线定位技术的室内导游系统,具体工作如下:1)分析了当前智能导游系统的研究现状和应用场景,确认当前电子导游系统的研究不足,确定了本课题必要性,并确定了具体的研究内容:基于室内无线定位技术的室内导游系统。2)详细分析了当前所流行的室内定位技术的研究现状,各技术的特点和应用场景。根据本课题的应用场景,确定了本文要使用的相关技术,并实现了本文中提出的定位算法,具体为:(1)通过分析超低功耗蓝牙的协议特点,进行节点硬件选型和节点软件设计,实现了一套基于BLE4.0的室内定位系统;(2)在前期WIFI指纹库定位方式的基础上,经过优化建库和匹配的过程进一步提高室内定位精度;(3)结合BLE4.0及WIFI室内定位技术,设计和实现了一种适用于文化旅游推送服务的新的室内定位方案。3)使用C/S架构,使用Android移动平台、百度云推送技术实现了基于室内定位技术的室内导游系统,该系统可根据用户的具体位置提供与位置信息相关的导游服务。4)以某大学计算机学院4楼为实验环境,对所实现的基于室内位置服务的电子导游系统进行了评估,其定位精度在3米以内,满足预期要求。
[Abstract]:Tourism is playing an increasingly important role in our economy. At present, many enterprises and institutions have launched tourism-related mobile application systems, which have been studied and popularized around travel planning and ticketing. However, these applications realize a single form of guided tour in scenic spots, lack of individualization and initiative. In order to enhance the attraction of scenic spots and enhance the autonomy of tourists when visiting, This paper designs and implements the indoor tour guide system based on the indoor wireless positioning technology. The specific work is as follows: 1) analyzing the current research status and application scene of the intelligent guide system, confirming that the current research of the electronic guide system is insufficient. The necessity of this subject is determined, and the specific research contents are determined: the indoor guided tour system based on indoor wireless positioning technology. (2) the current research status of the popular indoor positioning technology is analyzed in detail. According to the application scenario of this topic, the related technologies are determined, and the localization algorithm proposed in this paper is implemented, specifically, the protocol features of ultra-low power Bluetooth are analyzed. The node hardware selection and node software design are carried out, and a set of indoor positioning system based on BLE4.0 is realized. Based on the previous WIFI fingerprint database location mode, After optimizing the process of building database and matching, we further improve the accuracy of indoor positioning. Combined with BLE4.0 and WIFI indoor positioning technology, we design and implement a new indoor positioning scheme. 3) using C / S architecture, which is suitable for cultural tourism push service. Using Android mobile platform, Baidu cloud push technology to realize the indoor guided tour system based on indoor positioning technology, The system can provide guided guide service related to location information according to the specific location of the user. 4) taking the 4th floor of a university computer college as the experimental environment, the electronic guide system based on indoor location service is evaluated. Its positioning accuracy is less than 3 meters, meet the expected requirements.
