【摘要】：計量是科學賴以發(fā)展的支柱,并在生活的方方面面得到實際的應用,計量機構(gòu)承擔著執(zhí)行檢定/校準任務(wù)、保障量值傳遞準確可靠的職責,隨著科技進步和人們生活水平的提高,計量工作已經(jīng)具有相當?shù)膹碗s度和數(shù)據(jù)的冗余度,而絕大多數(shù)計量機構(gòu)依然采用紙質(zhì)記錄的方式,效率低下、信息共享困難、數(shù)據(jù)無法有效存儲和檢索,極大的阻礙了計量工作的有效展開�？紤]到互聯(lián)網(wǎng)+成為國家重點支持的研究熱點,計量管理向網(wǎng)絡(luò)化方式轉(zhuǎn)變成為突破口。計量業(yè)務(wù)管理系統(tǒng)由信息管理和檢測業(yè)務(wù)兩部分組成,本文針對計量信息管理系統(tǒng)進行了設(shè)計與實現(xiàn)。系統(tǒng)涉及的主要內(nèi)容為:1、計量機構(gòu)的部門、用戶、角色授權(quán)、模塊劃分、功能部署等系統(tǒng)信息的管理;2、計量規(guī)程規(guī)范的維護和數(shù)字化原始記錄模板的構(gòu)建,以及原始記錄中數(shù)據(jù)修改的留痕;3、計量標準器的信息管理和周期性檢定/校準;4、將系統(tǒng)用戶的操作寫入日志文件,提供日志信息、器具狀態(tài)和任務(wù)統(tǒng)計等的查詢。其中,本文有兩個關(guān)鍵問題,其一是數(shù)字化原始記錄的模板問題,計量器具的數(shù)量持續(xù)增長、規(guī)程規(guī)范的更新不斷加快,同時紙質(zhì)原始記錄存在低效、易出錯、不易存儲和檢索的弊端。本文整合規(guī)程規(guī)范的結(jié)構(gòu)、內(nèi)容提取出通用的控件庫,通過拖拽控件的方式組裝模板、調(diào)用公式庫自動計算檢定結(jié)果、檢索數(shù)據(jù)庫提取計量器具的基本信息等方式生成數(shù)字化、標準化的原始記錄模板;其二是數(shù)據(jù)留痕問題,數(shù)字化原始記錄模板無法像紙質(zhì)記錄一樣保留筆跡、不支持劃改數(shù)據(jù)、無法同時展示修改痕跡,無法確保原始數(shù)據(jù)的不可更改性。在檢定任務(wù)的執(zhí)行過程中,初次創(chuàng)建原始記錄時通過獲取文本框的焦點、監(jiān)聽鍵盤鍵值的方式確保錄入數(shù)據(jù)的更改留痕,針對存在舊版本的原始記錄,從文本、數(shù)值、選擇框三種數(shù)據(jù)類型的比較獲取原始記錄的修改內(nèi)容,其中文本比較采用LCSS算法,快捷高效。計量信息管理系統(tǒng)構(gòu)建了基于控件的原始記錄模板的創(chuàng)建環(huán)境,為絕大多數(shù)計量器具提供規(guī)范化模板的生成,同時支持器具信息的自動導入、檢定數(shù)據(jù)的有效性判定以及檢定結(jié)果的自動運算,提高了判定結(jié)果的準確性、可靠性和客觀性;采用分階段留痕的方式保證記錄的原始性,實現(xiàn)檢定數(shù)據(jù)的合法性;提供數(shù)字化平臺實現(xiàn)機構(gòu)內(nèi)數(shù)據(jù)信息的共享,優(yōu)化管理者的決策方式和手段、解決部門間的協(xié)同工作和信息傳遞、提高機構(gòu)工作的整體效率,為廣大人民群眾提供了可靠、準確、便捷的技術(shù)服務(wù)保障。本系統(tǒng)已經(jīng)上線并平穩(wěn)運行一年,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.
