血液冷链分布式无线多点温度监测系统设计

背景：由于血液及血液制品与‘般药品不同,当血液处于体外环境时,为保存生物活性,其各种成分都需要不同的储存温度。为保证其安全有效和质量可靠,避免因储藏或运输时温度过高或过低而影响了质量,就必须依靠血液冷链。目的：针对目前国内血液冷链管理存在的问题,提出一种在运送血液及血液制品的冷链过程中引入分布式多点温度监测系统的解决方案。方法：该系统采用数字温度传感器结合单片机和无线通信技术与PC实现分布式温度监测,智能判断温度值是否异常并进行报警处理,结合利用VisualC#2008开发的上位机管理程序,可实现同时对多个从机系统的集中监控。结果与结论：经多次重复实验证明,系统运行稳定,可靠性良好。

Design of distributed wireless multi-point temperature measuring system in blood cold chain

BACKGROUND： Blood and blood products are different from general drugs, they need different storage temperatures fo preservation of biological activity when they are in in vitro environment. In order to ensure safe, effective and reliable quality, blood cold chain is necessary to avoid a fact that too high or low temperature influences the quality of blood or blood products. OBJECTIVE： Based on the existing problems of present domestic blood cold chain management, this paper proposed ar application of distributed wireless multi-point temperature measuring system. METHODS： The system used the technology of 1-wire digital sensor, wireless communication and single-chip microcomputer in the management. It can intelligently identify the abnormal temperature fluctuation and alarm. The PC monitoring software was designed by using Visual C# 2008, which can monitor many slave systems simultaneously. RESULTS AND CONCLUSION： Repeated experiments show that the system operates stably and has good reliability.
