基于ZigBee的智能称重计价果蔬篮控制系统设计

电子秤采用手动输入货品名称匹配单价以计算物品总价的人工计价方式，称重效率低、人力成本较高且易出错.针对上述问题，设计了一套基于ZigBee的智能称重计价果蔬篮控制系统.该系统以CC2530为核心芯片，多个质量节点与协调器之间通过ZigBee无线网络互联，协调器与上位机通过串口互联.质量节点内嵌于果蔬篮底部并逐一编号，自动获取物品质量发送至协调器，协调器读取当前质量节点的编号和物品质量并输出至上位机，上位机生成并显示打印物品信息.智能称重计价果蔬篮控制系统无需人工操作，能自动识别物品并智能称重计价，从而可以提高称重效率和降低人力成本.

A New Zigbee-Based Fruit and Vegetable Basket Control System Featured with Intelligent Weighing and Pricing

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.
