【摘要】：隨著信息化、網(wǎng)絡(luò)化和數(shù)字化時代的到來,各領(lǐng)域的技術(shù)融合成為未來產(chǎn)品的發(fā)展趨勢。物聯(lián)網(wǎng)作為世界信息產(chǎn)業(yè)的第三次浪潮,綜合了多項技術(shù),實現(xiàn)了物與物之間的連接。本文從物聯(lián)網(wǎng)的角度思考,對物聯(lián)網(wǎng)、網(wǎng)絡(luò)技術(shù)與數(shù)據(jù)庫三者的結(jié)合進(jìn)行了探討,研究了一套通用的數(shù)據(jù)服務(wù)系統(tǒng),并對該系統(tǒng)的框架結(jié)構(gòu)進(jìn)行了分析和設(shè)計,將其主要分為三個模塊:基于嵌入式的數(shù)據(jù)采集接收模塊、基于網(wǎng)絡(luò)的數(shù)據(jù)傳輸模塊和基于數(shù)據(jù)庫的數(shù)據(jù)存儲與管理模塊。針對結(jié)構(gòu)中各模塊的方案進(jìn)行了探討、分析與比較,為具體應(yīng)用實現(xiàn)奠定了基礎(chǔ);最后以塔機(jī)遠(yuǎn)程監(jiān)測與衛(wèi)星導(dǎo)航模擬信號源為應(yīng)用背景,對此系統(tǒng)進(jìn)行了應(yīng)用研究。以塔機(jī)遠(yuǎn)程監(jiān)測為例,基于物聯(lián)網(wǎng)的三層結(jié)構(gòu),探討分析了系統(tǒng)軟硬件架構(gòu)。首先對硬件平臺選擇進(jìn)行了分析闡述,完成了Wince嵌入式系統(tǒng)的定制、裁剪;然后分析了三層C/S軟件構(gòu)架的實現(xiàn),實現(xiàn)了基于以太網(wǎng)的UDP遠(yuǎn)程數(shù)據(jù)實時傳輸;并基于SQL Server數(shù)據(jù)庫系統(tǒng),設(shè)計創(chuàng)建了塔機(jī)群數(shù)據(jù)庫,采用ADO數(shù)據(jù)庫訪問技術(shù)實現(xiàn)了數(shù)據(jù)庫的連接、讀寫等操作,最后通過功能測試,很好地實現(xiàn)了遠(yuǎn)程監(jiān)測功能,證實了該數(shù)據(jù)服務(wù)系統(tǒng)的可行性。以衛(wèi)星導(dǎo)航模擬信號源為例,分析了模擬信號源的系統(tǒng)架構(gòu),并將數(shù)據(jù)服務(wù)系統(tǒng)理論應(yīng)用于導(dǎo)航數(shù)據(jù)、軌跡最佳路徑等配置參數(shù)的更新實現(xiàn)。首先基于SQL Server數(shù)據(jù)庫系統(tǒng),設(shè)計創(chuàng)建了GPS導(dǎo)航數(shù)據(jù)庫,采用ADO數(shù)據(jù)庫訪問技術(shù)實現(xiàn)了數(shù)據(jù)庫的連接、讀寫等操作,并實現(xiàn)了基于以太網(wǎng)的TCP遠(yuǎn)程數(shù)據(jù)傳輸,為信號源提供了實時的導(dǎo)航數(shù)據(jù);然后采用C++與Matlab聯(lián)合編程,模擬生成了GPS中頻信號,最后經(jīng)過其它硬件模塊轉(zhuǎn)換生成衛(wèi)星導(dǎo)航信號,用接收機(jī)對其進(jìn)行了定位測試,定位結(jié)果與預(yù)期一致,表明了該數(shù)據(jù)服務(wù)系統(tǒng)的有效性。
[Abstract]:With the development of information technology, network and digital era, the field of technology integration has become the future development trend of the product. The Internet of things as the third wave of global information industry, integrated technology, realize the connection between objects and objects. The thinking of things from the perspective of things, the combination of network technology and database the three discusses the research, a general data service system, and the frame structure of the system are analyzed and designed, which is mainly divided into three modules: data acquisition module based on embedded receiver, data transmission module based on network and based on the data storage and database management module. For each module in the structure of the scheme is discussed, and the comparative analysis, laid the foundation for the realization of the tower crane; remote monitoring and satellite navigation simulation signal source for application background In this regard, the system was studied. The tower crane remote monitoring as an example, the three layer structure of IOT based on the analysis of the system hardware and software architecture. The choice of hardware platform are analyzed, and completed the Wince embedded system customization, tailoring; then analyzes the three layer C/S architecture, realized UDP remote data real-time transmission based on Ethernet; and based on SQL Server database system, the design of tower crane group created a database, using ADO database access technology to realize the database connection, read and write operations, and finally through the functional test, good implementation of the remote monitoring function, confirm the feasibility of the data service system by satellite. Navigation simulation signal source for example, analyzes the system architecture of the analog signal source, and the application of data service system theory in the navigation data, the best path track configuration parameters of the real update At first. Based on the SQL Server database system design, create a GPS navigation database, using ADO database access technology to realize the database connection, read and write operations, and implement the TCP remote data transmission based on Ethernet, to provide real-time data for the navigation signal; then the C++ and Matlab joint programming, simulate GPS intermediate frequency signal, finally through the other hardware module to convert the satellite navigation signal, the positioning test used in the receiver, the positioning results are consistent with expectations, show the effectiveness of the data service system.
