【摘要】：記錄儀表是檢測(cè)和記錄工業(yè)生產(chǎn)過(guò)程數(shù)據(jù)的工具，對(duì)于現(xiàn)代自動(dòng)化工業(yè)系統(tǒng)來(lái)說(shuō)是不可或缺的記錄儀表。傳統(tǒng)的無(wú)紙記錄儀受到處理器運(yùn)行速度和Flash容量的限制，導(dǎo)致對(duì)數(shù)據(jù)的處理和查詢速度較慢，而且無(wú)法存儲(chǔ)大容量的采集數(shù)據(jù)等問(wèn)題。 本文首先確定了記錄儀整體結(jié)構(gòu)的設(shè)計(jì)方案。然后設(shè)計(jì)了以ARM為處理核心的記錄儀主機(jī)的硬件電路，在linux操作系統(tǒng)下，編寫了采集、存儲(chǔ)、界面的應(yīng)用程序。設(shè)計(jì)了以STM32處理核心的記錄儀功能子板，，包括萬(wàn)能輸入板卡、電壓電流板卡、報(bào)警板卡。最后，通過(guò)PCB制版和機(jī)械殼體設(shè)計(jì)實(shí)現(xiàn)了記錄儀的樣機(jī)，并對(duì)設(shè)計(jì)的記錄儀進(jìn)行了測(cè)試，測(cè)試結(jié)果表明本課題所研究的記錄儀表運(yùn)行穩(wěn)定、符合本文預(yù)期的設(shè)計(jì)要求。 本文設(shè)計(jì)的記錄儀具有靈活的配置界面、密碼安全管理、便于維護(hù)和升級(jí)的應(yīng)用程序框架等優(yōu)點(diǎn)。采用基于單一文件的sqlite數(shù)據(jù)庫(kù)來(lái)保存采集數(shù)據(jù)，通過(guò)sql語(yǔ)句實(shí)現(xiàn)對(duì)歷史數(shù)據(jù)的快速高效的查詢工作。采用具有高速和高可靠性的CAN總線串行通訊方式來(lái)實(shí)現(xiàn)主機(jī)與功能子板之間的數(shù)據(jù)交互。系統(tǒng)在硬件電路上，采用功能子板的插卡式結(jié)構(gòu)來(lái)提高記錄儀采集各種類型傳感器數(shù)據(jù)的適應(yīng)能力。主機(jī)與子板的通訊協(xié)議允許記錄儀擴(kuò)展需要的子板板卡類型。人機(jī)交互界面采用曲線、數(shù)據(jù)、表格、棒圖的形式來(lái)顯示功能子板采集的實(shí)時(shí)數(shù)據(jù)。
[Abstract]:Recording instrument is a tool to detect and record the data of industrial production process. It is an indispensable instrument for modern automatic industrial system. The traditional paperless recorder is limited by the speed of the processor and the capacity of Flash, which leads to the slow processing and querying speed of data and the inability to store large capacity of collected data. This paper first determines the overall structure of the recorder design. Then the hardware circuit of the main computer of the recorder which takes ARM as the processing core is designed. Under the linux operating system, the application program of acquisition, storage and interface is written. The function subboard of STM32 processing core recorder is designed, including universal input card, voltage and current board and alarm board. Finally, the prototype of the recorder is realized by PCB plate-making and mechanical shell design. The test results show that the recording instrument studied in this paper runs stably and meets the expected design requirements. The recorder designed in this paper has the advantages of flexible configuration interface, password security management, easy maintenance and upgrade of the application framework. The sqlite database based on a single file is used to save the collected data, and the fast and efficient query to the historical data is realized by the sql statement. The CAN bus serial communication mode with high speed and high reliability is adopted to realize the data exchange between the host computer and the functional subboard. In the hardware circuit, the system adopts the card structure of the functional subboard to improve the adaptability of the recorder to collect the data of various kinds of sensors. The host-subboard communication protocol allows the recorder to expand the type of sub-board card required. The interface uses curves, data, tables and bar diagrams to display real-time data collected by functional subboards.
