Design of Intelligent Public Roll Paper Box System based on Raspberry Pi（基于树莓派的智能公共纸盒系统设计）

随着物联网技术的发展，人们对当前公共场所设施的智能化需求也越来越高。针对公共场所纸盒智能化需求，文章设计一款基于树莓派的智能公共纸盒系统。该系统实现了伸手感应自动出纸、出纸长度可控、纸张余量检测等功能，并可将相关数据通过树莓派开发板中配备的 WiFi 模块传输到云服务器中，以便配套的 Web 端获取和展示数据。管理人员通过 Web 端查看数据，掌握纸盒纸张剩余情况，确保纸盒可及时补充卷纸，从而实现纸盒的远程管理。相比于传统公共纸盒，文中设计的智能公共纸盒能够更好地管理公共纸盒，可防止缺纸和盗用卷纸现象发生，同时能减少公共资源的消耗。

With the development of the Internet of Things technology, people’s demand for the intelligentization of current public facilities is increasing. Aiming at the intelligent demand of roll holder box in public places, this article designs an intelligent public roll holder box system based on Raspberry Pi. The system realizes the functions of reaching out and sensing automatic paper output, controllable paper output length, remaining paper detection, etc. It can transmit the relevant data to the cloud server through the WiFi module equipped with the Raspberry Pi development board to facilitate the matching Web Panel. Get and display data. Managers can view the data through the Web Panel, grasp the remaining paper in the carton, and ensure that the carton can replenish the roll paper in time to realize the carton’s remote management. Compared with the traditional public roll holder box, the intelligent public carton designed in this paper can better manage the public carton, prevent the phenomenon of paper shortage and misappropriation of rolled paper, and reduce the consumption of public resources.
