【摘要】：無線電磁作為無線通信中信息的載體，在當(dāng)今無線電技術(shù)和業(yè)務(wù)飛速發(fā)展的背景下，變得越來越稀缺和珍貴，各種基于無線頻譜應(yīng)用的信息化進(jìn)程正呈現(xiàn)井噴式的發(fā)展。因此對(duì)無線電磁頻譜進(jìn)行有效和高效的管理和分配，提高頻譜的利用率，已經(jīng)成為業(yè)界研究和探討的熱門課題。 本論文以國家科技重大專項(xiàng)“傳感器網(wǎng)絡(luò)電磁頻譜監(jiān)測關(guān)鍵技術(shù)研究”項(xiàng)目為背景，，設(shè)計(jì)并實(shí)現(xiàn)了用于無線電磁頻譜監(jiān)測的任務(wù)管理中心軟件系統(tǒng)。本文首先從電磁頻譜監(jiān)測網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu)和網(wǎng)絡(luò)架構(gòu)，TCP/IP協(xié)議棧中應(yīng)用層協(xié)議和軟件系統(tǒng)架構(gòu)等方面對(duì)本系統(tǒng)進(jìn)行了詳細(xì)的分析和設(shè)計(jì)。然后設(shè)計(jì)并實(shí)現(xiàn)了本系統(tǒng)中一個(gè)重要的業(yè)務(wù)模塊—定位跟蹤模塊。通過分析和設(shè)計(jì)定位算法，定位跟蹤流程和協(xié)議以及數(shù)據(jù)的處理，實(shí)現(xiàn)了對(duì)未知信號(hào)源的定位跟蹤功能。其中定位跟蹤算法包括TDOA和RSSI兩種，保證了定位結(jié)果的準(zhǔn)確性和有效性，定位過程中的兩次節(jié)點(diǎn)推薦算法提高了定位的效率。 最后在真實(shí)的頻譜監(jiān)測網(wǎng)絡(luò)中，對(duì)系統(tǒng)進(jìn)行了功能和性能兩方面的測試。具體分析了定位跟蹤的誤差，定位的效率以及跟蹤的吞吐率。結(jié)果表明，系統(tǒng)完全達(dá)到了定位跟蹤的目標(biāo)。
[Abstract]:As the carrier of information in wireless communication, wireless electromagnetic is becoming more and more scarce and precious under the background of the rapid development of radio technology and services. Various information processes based on wireless spectrum applications are showing blowout development. Therefore, the effective and efficient management and allocation of wireless electromagnetic spectrum and the improvement of spectrum efficiency have become a hot topic in the field of research and discussion. In this paper, a task management center software system for wireless electromagnetic spectrum monitoring is designed and implemented under the background of the project "Research on key Technologies of electromagnetic Spectrum Monitoring in Sensor Networks", which is a major national science and technology project. In this paper, the topology of the electromagnetic spectrum monitoring network and the application layer protocol and software system architecture in the TCP / IP stack are analyzed and designed in detail. Then we design and implement an important business module in this system-positioning and tracking module. By analyzing and designing the localization algorithm, locating and tracking flow and protocol, and data processing, the function of locating and tracking unknown signal sources is realized. The localization and tracking algorithms include TDOA and RSSI, which ensure the accuracy and effectiveness of the localization results. The two-node recommendation algorithm in the localization process improves the efficiency of location. Finally, the function and performance of the system are tested in the real spectrum monitoring network. The error, efficiency and throughput of tracking are analyzed in detail. The results show that the system can reach the target of location and tracking.
