基于Wi-Fi无线通信技术的商用冰箱控制系统

摘要

针对目前大型酒店及超市在使用商用冰箱时,存在的保鲜效果差、食品存储状况差等缺点,提出了基于Wi-Fi无线通信技术的商用冰箱控制系统.设计了基于Wi-Fi无线通信技术的控制系统的硬件结构,介绍了CPU主控单元及温度检测原理;采用串口转Wi-Fi模块实现多台冰箱的无线组网,开发了基于光电开关的自动条码扫描模块、整个系统的电源管理模块以及掉电保护功能.采用分布式软件设计思想,设计了冰箱控制系统的软件,包括上位机控制软件以及现场控制软件.%Abstract:Due to some shortcomings of commercial refrigerator used in large hotels and supermarkets,such as poor effect of fresh-keeping,bad food storage condition,etc,a smart control system of commercial refrigerator based on wireless network Wi-Fi was proposed.A hardware structure of the control system was developed and CPU control unit,temperature detection principle were introduced.Using serial port transfer to Wi-Fi module realized the wireless networking between multi-refrigerators.An automatic bar code scanning module based on photoelectric switch was designed.And a power management module of whole control system and power-down protection were also put forward.The software of refrigerator control system,including PC control and on-site control was proposed.
