| 摘 要： | 针对动物食品生产流程,探讨了可追溯系统中关键标识技术的设计问题。通过读写器与电子标签的实际测试得出下列结果:随着数据传输率呈倍数的减小,通讯距离和信号强度都逐渐增加;采用60kbps或者10kbps数据传输率时,均能达到较好的通讯效果,可在50m范围内准确识别。实际应用时可根据标签的阅读量、通信距离的远近和干扰情况来选择其中的参数。

| Abstract: | Aiming at the production process of animal food, the design problems of the key marking technique in traceability system of animal food were discussed. The test results of the reader and electronic tag showed that the communication distance and signal intensity gradually increased with the multiple decrease of data transfer rate. When data transfer rate was 60 kbps or 10 kbps, better communication effect could be achieved. And the signal could be accurately identified in the range of 50 m. The parameters should be chosen in the actual application according to the reading quantity of tags, the communication distance and disturbance conditions. |
