无线点菜系统的设计

针对餐饮业传统点菜方式效率低下的问题,设计一种具有无线功能的智能化点菜系统.采用Qt应用程序框架完成点菜系统的硬件设计,硬件设计环境是Linux操作系统.软件设计基于服务器端和客户端设计模式,客户端根据客户的操作向服务器端发送请求,服务器端采用多线程技术实时响应客户端的请求;使用C++编程语言实现系统的客户端和服务器端,通过SQLite数据库管理服务器端的数据信息,Wi-Fi技术实现服务器端和客户端之间的无线通信.实验表明系统有较好的操作性和安全性.

Design of wireless ordering system

In view of the problem of low efficiency in traditional method of order,a wireless intelligent ordering system was designed,including hardware design and software design.We used Qt application framework for designing hardware of the ordering system and used the Linux operating system as the hardware design environment.We designed software based on the server and client design pattern,in which client sends a request to server according to the customer＇s operation,server responses to client request in real time by the multithreading technology.Finally,we used C＋＋programming language to implement the system of client and server,SQLite database to manage data on the server,Wi-Fi technology to communicate between the server and the client.The result indicates that the system has better efficiency and safety.
