A Comprehensive Monitoring and Controlling System for Multifunctional Direct Drinking Machine Based on IoT

A remote monitoring system of multifunctional direct drinking machine based on Internet of things (IoT) is designed in this paper. The local control system detected the status data of water purifiers according to the temperature sensor, the flowmeter and the water level gauge, then sent the collected parameters to the backstage management system in the cloud by General Packet Radio Service (GPRS) communication network or Wireless Fidelity (WIFI) in real time. Prototype design and applications show that the management system has friendly user interface and is easy to be operated. It may display the working states of the direct drinking machine in real time, manage big data, and support remote operation of the equipment. Radio frequency identification (RFID) technology and mobile payment technology are employed to realize automatic user identification, water purchase, information maintenance and other functions. The comprehensive monitoring and controlling system has realized the function of connecting users and multifunctional direct drinking machines in the Internet of things, which has good application potential.
