【摘要】：辐照加工技术在社会生活的各个方面已经得到了极为广泛的应用，国家剂量保证服务可以统一辐照装置的吸收剂量量值，对于保证辐照加工的质量和安全具有重要意义。国家剂量保证服务的实施流程中需要大量的数据处理工作，，因此我研发了服务于国家剂量保证服务的自动数据处理系统，自动数据处理不仅提高剂量保证服务的准确性和可靠性，而且提升了检测部门提供国家剂量保证服务的能力。论文在认真细致梳理国家剂量保证服务流程的基础上，对国家剂量保证服务中的要点和可能出现的问题进行了具体的分析。经过梳理和分析，可以发现数据处理已经成为国家剂量保证服务的重要组成部分。传统的手工计算工作量大，精度低，可靠性低，为此引入自动数据处理技术已经十分迫切。论文梳理了NDAS中数据处理任务，对拟合校准曲线及其准确性分析进行数学推导，对于校准曲线中的野点剔除提出了高效率的自动解决方案；为实现自动数据处理系统打下了很好的基础。然后按照软件开发流程，从需求分析，系统设计实现到性能测试，论文完成了NDAS自动数据处理系统的开发；并且通过试用和培训，将NDAS自动数据处理系统投入了实用。论文通过理论分析和数据测试验证了自动数据处理系统的正确性。引入了自动数据处理系统后，改善了数据处理的效率和可靠性，提升了国家剂量保证服务的能力。
[Abstract]:Radiation processing technology has been widely used in various aspects of social life. The national dose guarantee service can unify the absorbed dose value of irradiation device, which is of great significance to ensure the quality and safety of irradiation processing. The implementation of the national dose assurance service requires a lot of data processing, so I have developed an automated data processing system for the national dose assurance service. Automatic data processing not only improves the accuracy and reliability of dose assurance service, but also enhances the ability of testing department to provide national dose assurance service. On the basis of carefully combing the process of national dose assurance service, this paper makes a concrete analysis of the main points and possible problems in the national dose assurance service. After combing and analysis, we can find that data processing has become an important part of the national dose assurance service. The traditional manual calculation has the characteristics of large workload, low precision and low reliability, so it is very urgent to introduce automatic data processing technology. In this paper, the task of data processing in NDAS is combed, and the mathematical derivation of fitting calibration curve and its accuracy analysis is carried out, and an efficient and automatic solution for eliminating outliers in calibration curve is put forward. It lays a good foundation for the realization of automatic data processing system. Then according to the software development process, from requirement analysis, system design to performance testing, the paper completed the development of NDAS automatic data processing system, and put the NDAS automatic data processing system into practice through trial and training. The correctness of the automatic data processing system is verified by theoretical analysis and data test. With the introduction of automatic data processing system, the efficiency and reliability of data processing are improved, and the capacity of national dose assurance service is enhanced.
