目的 基于无线射频识别( RFID) 技术的药品冷链监控系统数据传输程序设计。 方法 首先解决监控对象的温湿度信息采集和分布式多标签数据读取的冲突问题,然后解决数据由传感器经读写器、车载 GPRS 模块至中心服务器的数据传输通讯问题。 结果 基于 UDP 网络传输协议平台,设计开发了 CRC 校验码和防冲突算法通讯接口程序。 结论 实现了数据采集传输的实时性、完整性和准确性,为进一步开发冷链监控系统奠定了基础。

Objective To design data transfer program for Medical Cold-Chain Monitoring System based on RFID. Methods First of all, the humiture information was collected and the conflict problem of Labels was solved; and then the transmission and communication problem during the data transmission from sensor to RFID reader and from GPRS module to central server was solved. Results Based on the UDP-protocol network transmission platform, acommunication interface program of CRC and anti-collision was designed and developed. Conclusion The real-timeness, integrity and accuracy of data collection and transmission were realized, which builds a solid foundation for the further development of Cold-chain Monitoring system.
