【摘要】:無線通信技術(shù)的快速發(fā)展正在改變著人們的生活方式,社會的需求也在不斷的激發(fā)新技術(shù)的產(chǎn)生。多制式網(wǎng)絡(luò)為用戶提供優(yōu)質(zhì)服務(wù)的同時,造就了空口信息多樣性和復(fù)雜性的局面。使用路測系統(tǒng)獲取網(wǎng)絡(luò)信息是常用的網(wǎng)絡(luò)優(yōu)化手段。然而目前,業(yè)內(nèi)大多數(shù)路測軟件需要與路測終端、便攜式電腦、GPS等外設(shè)搭配,且僅支持路測終端對應(yīng)網(wǎng)絡(luò)制式的空口信息采集功能,路測系統(tǒng)集成性與便攜性有待提高。 本文專注于嵌入式多?湛谛畔⒉杉到y(tǒng)的設(shè)計與實現(xiàn),旨在利用單片嵌入式系統(tǒng)的高度集成特性、自動化特性和便攜性等特點。該系統(tǒng)無需其他外部設(shè)備和人工操作,自動運行并記錄多制式無線網(wǎng)絡(luò)參數(shù)信息,改善空口信息采集工作效率。 本文完成的主要工作有:根據(jù)系統(tǒng)需求分析,基于控制時序關(guān)系,制定系統(tǒng)模塊間通信協(xié)議。完成GPS模塊和文件管理模塊的設(shè)計與實現(xiàn):GPS模塊遵循NMEA-0183協(xié)議標準規(guī)范,采集經(jīng)緯度、UTC時間等路測信息,除此之外該模塊為系統(tǒng)提供時鐘基準,是保證系統(tǒng)內(nèi)部控制時序有序運行的基礎(chǔ);文件管理模塊為系統(tǒng)輸出數(shù)據(jù)信息存儲提供服務(wù),通過該模塊系統(tǒng)得以在SD數(shù)據(jù)卡中完成文件創(chuàng)建、文檔創(chuàng)建、字節(jié)寫入等文件管理操作,該模塊是系統(tǒng)內(nèi)信息采集與信息存儲的橋梁。同時,文件管理模塊是系統(tǒng)采集信息輸出窗口,通過輸出數(shù)據(jù)可驗證系統(tǒng)功能是否滿足預(yù)期設(shè)計。 系統(tǒng)實測結(jié)果滿足預(yù)期設(shè)計,驗證了本設(shè)計方案合理有效,開發(fā)模塊穩(wěn)定可靠,系統(tǒng)能夠自動記錄并存儲多制式網(wǎng)絡(luò)空口信息,達到無線網(wǎng)絡(luò)測試的要求。
[Abstract]:The rapid development of wireless communication technology is changing people's way of life. Multi-standard network provides high-quality service to users, and brings up the situation of diversity and complexity of empty-mouth information. It is a common method of network optimization to obtain network information by means of road measurement system. However, at present, most of the road testing software in the industry needs to be matched with the peripheral devices such as road test terminal, portable computer and GPS, and only supports the empty port information collection function of the road test terminal corresponding to the network mode. The integration and portability of the road test system need to be improved. This paper focuses on the design and implementation of the embedded multi-mode empty port information acquisition system, which aims to utilize the characteristics of high integration, automation and portability of the single-chip embedded system. The system can automatically run and record multi-standard wireless network parameter information without other external equipment and manual operation, and improve the efficiency of empty port information collection. The main work of this paper is as follows: according to the system requirement analysis, based on the control timing relationship, the communication protocol between modules of the system is established. The design and implementation of GPS module and file management module follow the standard specification of NMEA-0183 protocol, collect the time of longitude and latitude, etc. Besides, this module provides the clock reference for the system. The file management module provides the service for the storage of the output data information of the system, through which the file creation and document creation can be completed in the SD data card. Byte writing and other file management operations, this module is a bridge between information collection and information storage in the system. At the same time, the file management module is the output window of the system to collect information. The output data can verify whether the function of the system meets the expected design. The measured results of the system satisfy the expected design and verify that the design scheme is reasonable and effective, the development module is stable and reliable, and the system can automatically record and store the empty port information of multi-standard network, which can meet the requirements of wireless network testing.
