3、项目说明

技术栈描述：

Python语言：作为主要的开发语言，用于编写后端逻辑和数据处理。
Flask框架：用于构建Web应用程序，提供路由、请求处理和模板渲染等功能。
Echarts可视化：用于在Web页面中生成交互式图表，实现数据的可视化展示。
百度地图：通过百度地图API获取地理位置信息，实现地图显示和位置标注等功能。
SQLite数据库：作为轻量级的关系型数据库，存储系统中的监控数据。
HTML：用于构建前端用户界面，定义页面结构和内容展示。
智慧交通监控大数据系统是一个基于以上技术栈构建的系统，通过采集交通监控设备产生的数据，对数据进行处理和分析，然后使用Echarts可视化库将数据以图表的形式展示在Web页面上。百度地图可以用来显示交通状况、标注交通事件或热点区域。SQLite数据库用于存储交通监控设备采集的数据，支持数据的查询和管理。整个系统的前端界面则通过HTML来呈现给用户。
