摘　　要：在日常生活中,学校和企业具有严格的作息时间。食堂往往存在就餐人数集中拥堵,排队时间过长等问题,而且还会产生一些不文明的社会现象。为解决传统食堂点餐就餐的模式,设计了一种无线称重监测食堂菜品剩余量的系统,利用NRF24L01和HX711芯片的特点,将自动称重控制技术与无线通信技术有机结合起来。通过MySQL制作菜品剩余量的数据库,并由电脑、显示器和微信小程序向就餐人员动态实时的显示食堂所售菜品的各种信息。该系统的使用能够减少排队、等座时间,提高就餐效率,还能选择自己喜欢的菜品,极大地提高了就餐效率和服务质量。In daily life,schools and enterprises have strict work and rest time.There are many problems in canteen,such as crowded dining population,long queue time,and some uncivilized social phenomena.In order to solve the traditional mode of ordering and dining in canteen,this article designed a wireless weighing system to monitor the leftover quantity of canteen dishes.Using the characteristics of nRF24 L01 and hx711 chips,the automatic weighing control technology and wireless communication technology were organically combined.A database was established through mysql to show the leftovers of dishes,and display all kinds of information of the dishes sold in the canteen to the dining staff in real time by computer,display and wechat program.The use of the system can reduce the waiting time,improve the efficiency of dining,but also choose their favorite dishes,which can greatly improve the efficiency of dining and service quality.
