摘　　要：针对传统的纸质排队叫号系统对纸张的严重依赖,设计并实现一种基于低功耗Wi-Fi的电子号牌排队系统。硬件部分以CC3200芯片为基础,其内置的无线处理器以及Cortex-M4处理器为号牌的网络接入、业务显示和震动提醒等功能提供基础。叫号服务器端采用GO语言编写,对系统内部的电子号牌提供UDP报文无线广播、设置业务号码、发送叫号提醒等功能。对系统外部的应用提供HTTP接口功能,方便开发人员在本系统基础上二次开发,对接已有业务。Traditional calling and queuing systems rely heavily on paper. To solve this problem, we designed and implemented an electronic reminder device and queuing system based on low-power Wi-Fi. The hardware part was based on CC3200 chip. Its built-in wireless processor and Cortex-M4 processor provided the basis for several functions of reminder device such as network access, service display and vibrate remind. The reminder system service was developed by GO language. It provided UDP wireless broadcasting function for the electronic reminder device inside the system, set up service numbers, sent call reminders, and so on. It also provided HTTP interface function for the application outside the system. It is convenient for the developers to redevelop the system and dock the existing services.
