Abstract: Aiming at the existing fruit and vegetable cash register equipments can not realize the problem of simultaneous selfservice payment of multiple commodities, a fruit and vegetable cash integrated machine integrated with a variety of sensors such as camera, hx711 strain gauge and GPS is designed. The cash register uses MaixSense equipped with MaixPy3 firmware as the terminal processor, uses YOLO target detection model to identify the type of fruits and vegetables and NB-IoT mobile communication method to access the cloud. Compared with existing fruit and vegetable cash registers, the design can realize the functions of simultaneous identification and weighing, user payment and cloud data management of multiple types of fruit and vegetable products.
Keywords: fruit and vegetable cash register; simultaneous operation; weighing recognition cloud management
