摘　　要：为实现雪花牛肉生产信息高效采集与追溯,研发了基于无线传感网的雪花牛肉信息溯源系统。系统利用由STM32芯片、CC1101射频模块和SHT10传感器模块组成的节点采集温湿度数据,利用电荷耦合器件相机采集雪花牛肉等级信息,并发送信息至服务器储存。通过设计牛肉产品溯源编码将不同信息表链接,实现Web端雪花牛肉信息的远程追溯。结果表明:在低温高湿的生产环境中,系统采集温度误差在±0.3℃内,湿度误差在±1.0%内,牛肉图片采集时间在6 s左右,Web平台牛肉信息溯源成功率可达100%。雪花牛肉信息溯源系统能够稳定可靠地运行,从而实现各项功能。A snowflake beef information tracing system based on wireless sensor networks was developed to trace and collect information on snowflake beef effectively. In the system, nodes composed of STM32 chip, CC1101 radio frequency module and SHT10 sensor module were used to collect temperature and humidity data. The system collected information about snowflake beef grading with a charge-coupled device（CCD） camera and sent the data to the server for storage. The system connected different data tables with the designed traceability code to achieve remote tracing of the information on snowflake beef on the web. Results showed that, in low temperature and high humidity environment, the temperature error of the system was less than ± 0.3 ℃ and the humility error was less than ± 1.0%. It took about 6 seconds to photos of beef and the accuracy of tracing beef information on the web platform was 100%. The system could work steadily to implement each function normally.
