【摘要】：近年來,基于網(wǎng)絡(luò)的遠(yuǎn)程數(shù)據(jù)采集及遠(yuǎn)程監(jiān)控技術(shù)在各行各業(yè)得到了越來越多的應(yīng)用。借助遠(yuǎn)端的數(shù)據(jù)采集裝置記錄被監(jiān)控對象的運行數(shù)據(jù),并通過網(wǎng)絡(luò)將數(shù)據(jù)傳送至后方的計算機或服務(wù)器,根據(jù)數(shù)據(jù)分析和處理結(jié)果,判定被監(jiān)控對象的工作狀態(tài)并采取相應(yīng)的應(yīng)對措施。 本課題主要研究某武器控制系統(tǒng)的檢測與診斷技術(shù),旨在現(xiàn)有檢測技術(shù)基礎(chǔ)上探索性能更優(yōu)的技術(shù)方案。針對原有檢測系統(tǒng)中的數(shù)據(jù)采集問題,研究提高采樣速度、擴大采樣容量、快速保存數(shù)據(jù)、實時處理數(shù)據(jù)并及時發(fā)現(xiàn)設(shè)備故障的技術(shù)方案。 在研究原有的基于單任務(wù)操作系統(tǒng)DOS、硬件結(jié)構(gòu)符合PC/104總線標(biāo)準(zhǔn)的檢測系統(tǒng)的基礎(chǔ)上,提出了基于多任務(wù)操作系統(tǒng)Linux的設(shè)計方案。研究并定制了與硬件架構(gòu)相適應(yīng)的操作系統(tǒng)內(nèi)核、建立了根文件系統(tǒng)和系統(tǒng)引導(dǎo)程序；針對數(shù)據(jù)采集卡DIAMOND-MM-32-AT的工作原理及工作模式,編寫了相應(yīng)的設(shè)備驅(qū)動程序；利用socket編程以及多線程編程,編寫了能夠穩(wěn)定運行于下位機的實時數(shù)據(jù)采集和數(shù)據(jù)傳送程序,同時編寫了運行于上位機的數(shù)據(jù)接收與處理程序。 本論文詳細(xì)闡述了基于網(wǎng)絡(luò)的數(shù)據(jù)采集系統(tǒng)的硬件組成和軟件架構(gòu),并給出了實際運行結(jié)果,驗證了設(shè)計方案的可行性。
[Abstract]:In recent years, remote data collection and remote monitoring network technology has been used more and more in all walks of life. Based on the operation data by means of data acquisition device for recording remote monitored object, and transmits the data to the rear of the computer or server through the network, according to the data analysis and processing results, determine the working state of the monitored object and take corresponding measures.
Detection and diagnosis technology of the main research topics of a weapon control system, in order to explore the technical scheme of better performance based on the existing detection technology. Aiming at the problems existing in data acquisition and detection system, research to improve the sampling rate, sampling volume expansion, rapid data storage, real-time data processing and find technical solutions of equipment malfunction.
In the study of single task operating system DOS based on the original basis, the detection system hardware structure in accordance with the PC/104 bus standard, put forward a design scheme of Linux multi task operating system based on kernel operating system research and customize and adapt to hardware architecture, established the Gen Wen system and system boot program for data collection; the principle and working mode of DIAMOND-MM-32-AT card, write the corresponding device driver; using socket programming and multi thread programming, real-time data acquisition and data transfer program can run stably on the machine, at the same time to write the running in PC data receiving and processing procedures.
This paper elaborates the hardware composition and software architecture of data acquisition system based on network, and gives the actual operation results, which verifies the feasibility of the design plan.
