摘　　要：目的 医疗器械溯源种类众多,存储后的数据溯源时存在跨度大、数据丢失等问题,为提升医疗器械溯源数据存储性能,提出基于March算法的医疗器械溯源数据存储方法。方法 通过构建的滤波器对医疗器械溯源数据开展小波分解处理并实施阈值量化,结合混合熵编码对保留溯源数据系数编码,完成医疗器械溯源数据的压缩;采用建立的云存储模型存储压缩后的溯源数据,利用March算法遍历存储模型各个存储单元,测试出模型内是否存有故障,实现医疗器械溯源数据的最终存储,验证所提基于March算法的医疗器械溯源数据存储方法的有效性。结果 验证结果表明,该方法的平均剩余能量在400~500 nJ范围内,可存储溯源数据量5000个,存储标准差值均小于15。结论 基于March算法的医疗器械溯源数据存储方法的能量消耗较低,存储容量较大,负载均衡性能较好,可为医疗数据管理提供参考。Objective There are many kinds of traceability of medical devices,and there are problems such as large span and data loss in the traceability of stored data.In order to improve the storage performance of medical device traceability data,to propose a medical device traceability data storage method based on March algorithm.Methods Through the constructed filter,the medical device traceability data was decomposed by wavelet transform and quantized by threshold value.Combined with the mixed entropy coding,the coefficient of the retained traceability data was coded to complete the compression of the medical device traceability data.The established cloud storage model was used to store the compressed traceability data,and March algorithm was used to traverse each storage unit of the storage model to test whether there was any fault in the model,so as to realize the final storage of medical device traceability data,and the effectiveness of the medical device traceability data storage method based on the March algorithm was verified.Results The test results showed that the average residual energy of this method was in the range of 400-500 nJ,and 5000 traceable data could be stored,and the storage standard deviation was less than 15.Conclusion The medical device traceability data storage method based on March algorithm has low energy consumption,large storage capacity and better load balancing performance,which can provide reference for medical data management.
