【摘要】：计量是科学赖以发展的支柱,并在生活的方方面面得到实际的应用,计量机构承担着执行检定/校准任务、保障量值传递准确可靠的职责,随着科技进步和人们生活水平的提高,计量工作已经具有相当的复杂度和数据的冗余度,而绝大多数计量机构依然采用纸质记录的方式,效率低下、信息共享困难、数据无法有效存储和检索,极大的阻碍了计量工作的有效展开。考虑到互联网+成为国家重点支持的研究热点,计量管理向网络化方式转变成为突破口。计量业务管理系统由信息管理和检测业务两部分组成,本文针对计量信息管理系统进行了设计与实现。系统涉及的主要内容为:1、计量机构的部门、用户、角色授权、模块划分、功能部署等系统信息的管理;2、计量规程规范的维护和数字化原始记录模板的构建,以及原始记录中数据修改的留痕;3、计量标准器的信息管理和周期性检定/校准;4、将系统用户的操作写入日志文件,提供日志信息、器具状态和任务统计等的查询。其中,本文有两个关键问题,其一是数字化原始记录的模板问题,计量器具的数量持续增长、规程规范的更新不断加快,同时纸质原始记录存在低效、易出错、不易存储和检索的弊端。本文整合规程规范的结构、内容提取出通用的控件库,通过拖拽控件的方式组装模板、调用公式库自动计算检定结果、检索数据库提取计量器具的基本信息等方式生成数字化、标准化的原始记录模板;其二是数据留痕问题,数字化原始记录模板无法像纸质记录一样保留笔迹、不支持划改数据、无法同时展示修改痕迹,无法确保原始数据的不可更改性。在检定任务的执行过程中,初次创建原始记录时通过获取文本框的焦点、监听键盘键值的方式确保录入数据的更改留痕,针对存在旧版本的原始记录,从文本、数值、选择框三种数据类型的比较获取原始记录的修改内容,其中文本比较采用LCSS算法,快捷高效。计量信息管理系统构建了基于控件的原始记录模板的创建环境,为绝大多数计量器具提供规范化模板的生成,同时支持器具信息的自动导入、检定数据的有效性判定以及检定结果的自动运算,提高了判定结果的准确性、可靠性和客观性;采用分阶段留痕的方式保证记录的原始性,实现检定数据的合法性;提供数字化平台实现机构内数据信息的共享,优化管理者的决策方式和手段、解决部门间的协同工作和信息传递、提高机构工作的整体效率,为广大人民群众提供了可靠、准确、便捷的技术服务保障。本系统已经上线并平稳运行一年,效果良好。
[Abstract]:Measurement is the pillar of the development of science and has been applied in every aspect of life. The measurement organization is responsible for carrying out the task of verification / calibration and ensuring the accurate and reliable transmission of value. With the progress of science and technology and the improvement of people's living standard, metrology work has already had considerable complexity and data redundancy, while most metrology organizations still adopt the method of paper record, which is inefficient and difficult to share information. Data can not be stored and retrieved effectively, which greatly hinders the effective development of measurement work. Considering that the Internet has become a research hotspot supported by the state, the metrological management has turned into a breakthrough. The metrology service management system is composed of information management and detection service. This paper designs and implements the metrological information management system. The main contents of the system are the management of system information such as: 1, department of measurement organization, user, role authorization, module partition, function deployment, etc., the maintenance of metrological specification and the construction of digitized original record template. In addition, the information management and periodic verification / calibration of the metrological standard device are used to write the operation of the system user to the log file, and to provide the query of log information, instrument status and task statistics and so on, as well as the residual mark 3 of data modification in the original record, the information management and periodic verification / calibration of the metrological standard. Among them, there are two key problems in this paper, one is the template problem of digital original record, the quantity of measuring instruments keeps increasing, the updating of rules and regulations is speeding up, and the paper original record is inefficient and error-prone. The disadvantages of not easy to store and retrieve. This paper integrates the structure of regulation specification, extracts the general control library, assembles the template by dragging and dropping the control, calls the formula library to automatically calculate and verify the results, and retrieves the basic information of the measuring instruments in the database to generate digitization. Standardized original record template; second, the problem of data mark, digital original record template can not keep handwriting as paper records, do not support the marking of data, can not display changes at the same time, The immutability of the raw data cannot be ensured. In the execution of verification task, when the original record is created for the first time, the focus of the text box is obtained, the keypad key value is monitored to ensure the change mark of the input data, for the original record with the old version, from the text to the value, The comparison of the three data types in the select box acquires the modified content of the original record, in which the text comparison adopts LCSS algorithm, which is fast and efficient. The metrology information management system constructs the environment of creating the original record template based on the control, which provides the generation of the standardized template for most measuring instruments, and supports the automatic import of the instrument information. The validity of the verification data and the automatic operation of the verification results improve the accuracy, reliability and objectivity of the results, and ensure the originality of the records by using the method of keeping marks in stages, and realize the legitimacy of the verification data. To provide a digital platform for sharing data and information within the organization, to optimize the decision-making methods and means of managers, to solve the cooperative work and information transmission among departments, to improve the overall efficiency of the work of the organization, and to provide reliability for the broad masses of the people. Accurate, convenient technical service guarantee. The system has been on line and running smoothly for one year, the effect is good.
