基于树莓派的校园导游系统设计

Design of Campus Tour Guide System Based on Raspberry Pi

摘要: 随着信息化技术的不断发展，信息化社会的到来，数字化校园建设已成为高等学校发展的必然趋势，也是高校建设的重要组成部分，它是一项基础性、长期性和经常性的工作。为建设数字化校园，建设智能校园，本设计构建了一个校园导游系统。该系统由STC89C52单片机搭配树莓派3B+微型计算机来完成此次设计。单片机部分负责校园环境数据采集，树莓派部分负责完成语音识别、路径查询规划、语音合成的功能。该导游系统设计为一个WEB应用，运用Python语言下的Django框架实现，用户在WEB端发起语音输入请求，系统进行录音后调用百度语音识别API完成语音识别，调用高德地图的JS API来实现路径规划的功能。本系统完成了用户请求到响应的一系列逻辑代码的编写，配合外部硬件实时监测校园环境，最终设计出一款适合校园使用的导游系统。

Abstract: With the continuous development of information technology and the advent of information society, the construction of digital campus has become an inevitable trend in the development of colleges and universities, and it is also an important part of college construction. It is a basic, longterm and regular work. In order to build a digital and intelligent campus, this design constructs a campus tour guide system. This system is completed by STC89C52 Single-Chip Computer (SCM) with Raspberry Pi 3B + microcomputer. The SCM part is responsible for campus environment data collection, and the Raspberry Pi part is responsible for the functions of speech recognition, path query planning, and speech synthesis. The tour guide system is designed as a WEB application, which is implemented by using the Django framework in Python language. The user initiates a voice input request on the WEB side. After the system performs recording, the Baidu speech recognition API is called to complete the speech recognition. The function of path planning is implemented by calling the JS API of the Gaode map. By compiling of a series of logic codes from user request to response, and by cooperating with external hardware to monitor the campus environment in real time, finally the guide system that is suitable for campus is completed.
