Self-Help Service Terminal Based on Pyroelectric Infrared Sensor and Linux Operation System

摘要: 自助终端服务系统因其方便快捷的特性在社会生活中广泛应用，本文提出了基于热释电红外传感和Linux系统的自助终端设计与实现。该自助终端采用热释电红外传感实现终端系统的自动开关，在无人使用时低能耗运行；利用嵌入式Linux操作系统实现用户操作的简易和精确，实现了实时天气、便携设备自助充电、基于电子地图的公共设备(公共自行车站点、公交车站点、公共厕所地点、医院地点)定位搜索等城市公共服务的功能集成。具有成本低廉，界面老年人友好，适用于郊区与偏远街路的特点，是对提高城乡广大地区智能公共服务覆盖率和智慧城市建设有促进作用的基础设计与实现。

Abstract: With the increasing demand for public service, as well as the increasing application of pyroelectric infrared sensors and Internet, this paper designs a self-help public service terminal based on pyroelectric infrared sensor and Linux operation system. The terminal uses pyroelectric infrared sensing to make screen of the self-service terminal be auto-switch, and uses Linux operation system to make users’ controlling simple and easy and accurate. The design of the terminal achieves the function integration of urban life public services, which can be listed as real-time weather, outdoor mobile phone charging, electronic map, and so on. We hope the application of this terminal can expand the coverage of smart public services and promote the construction of smart cities to some extent.
