基于GSM的直饮水机远程网络化控制平台设计

针对直饮水机普遍存在的饮用水水质安全隐患、不易管理等问题,提出了一种基于GSM和Internet的直饮水机远程网络化控制平台的设计方案.分别设计了上位机模块、通信模块和下位机模块,设计了一种网站形式的信息交互平台,实现了可视化和人性化的操作与信息反馈;充分发挥了GSM和Internet网络两种通信手段的优势,通过采用短消息与网络通信相结合的信息传输方式,实现了信息的远程传递;根据双频电导率测定法原理,设计了一种基于CS5460A测量芯片的可集成饮用水水质检测模块,结合下位机各子模块的设计,实现了对直饮水机的水质监测与自动控制功能.研究结果表明,直饮水机远程网络化控制平台可方便地实现对直饮水机的水质监测、预警、实时维护、信息管理和远程控制等功能,确保直饮水机的饮用水水质安全.

Remote control platform for straight drinking fountains based on GSM

Aiming at solving the safety problems of drinking water from straight drinking fountains and reducing the difficulty of management,a remote control platform for straight drinking fountains based on the technology of GSM and Internet was proposed.The upper machine module,communication module and lower machine module were designed respectively.A website was designed to achieve a visual and user-friendly interface for operation and information feedback.By taking the advantages of GSM and Internet,a means of communication combining SMS and network was designed and used for remote communication.A kind of integrated detection module of drinking water quality based on the method of measuring water conductivity by double frequency sinusoidal signals was designed.Combining the design of each sub-module,the functions of water quality monitoring and automatic control were realized.The results indicate that,people can achieve many functions to control and monitor the straight drinking fountains on the platform,such as monitoring the water quality,obtaining the warnings,real-time maintenance,information management and remote control,etc.,to ensure the safety of drinking water.
