Abstract:

Electronic scale adopts manual input of good names to match the unit price, and then calculates the total price of the product. This method has low weighing efficiency, high labor cost and is prone to errors. To solve the above problems, a set of ZigBee￣based fruit and vegetable basket control system featured with intelligent weighing and pricing is designed. In the system, CC2530 is adopted as the core chip, multiple weight nodes and coordinator are inter connected through ZigBee wireless network, and the coordinator and the host computer are connected through serial port. The weight node is embedded at the bottom of the fruit and vegetable basket and numbered one by one, and the mass of the selected items is automatically obtained by the weight node and sent to the coordinator. Then, the coordinator reads the weight node number and the mass and outputs them to the host computer, which generates, displays and prints the item information. The system automatically identifies items and intelligently weighs and prices goods with no manual operation, thus significantly improving the efficiency of weighing and pricing as well as reducing labor costs.

Key words: intelligent weighing and pricing, fruit and vegetable basket, control system, ZigBee, CC2530
