本文以无线WIFI网络节点搭建的局域网为基础,使用C#语音编写的上位机软件通过TCP/IP协议与MT7681无线模块进行通信,使用sql server数据库来存储用户数据。登录智能酒店客房控制系统软件后,点击相应功能按键,上位机将会向所在局域网发送UDP数据包,MT7681无线模块识别并接收数据包后进行解析,通过IO口控制继电器工作状态来实现对客房内的“电源”和“热水器”的远程控制,提前控制,为酒店的管理与服务提供了便利,符合当前物联网趋势,实用性强。 Based on the LAN built by wireless WIFI network nodes, this paper uses PC software written by C # to communicate with MT7681 wireless module through TCP / IP protocol and uses sql server database to store user data. Login smart hotel room control system software, click the appropriate function button, the host computer will be sent to the local area network UDP packets, MT7681 wireless module to identify and receive data packets after the resolution, through the IO port to control the working status of the relay to achieve the room The remote control of “Power ” and “Water heater ”, which is controlled in advance, has facilitated the management and service of the hotel, is in line with the current trend of Internet of Things, and has strong practicability.
