【摘要】：无线通信技术的快速发展正在改变着人们的生活方式,社会的需求也在不断的激发新技术的产生。多制式网络为用户提供优质服务的同时,造就了空口信息多样性和复杂性的局面。使用路测系统获取网络信息是常用的网络优化手段。然而目前,业内大多数路测软件需要与路测终端、便携式电脑、GPS等外设搭配,且仅支持路测终端对应网络制式的空口信息采集功能,路测系统集成性与便携性有待提高。本文专注于嵌入式多模空口信息采集系统的设计与实现,旨在利用单片嵌入式系统的高度集成特性、自动化特性和便携性等特点。该系统无需其他外部设备和人工操作,自动运行并记录多制式无线网络参数信息,改善空口信息采集工作效率。本文完成的主要工作有：根据系统需求分析,基于控制时序关系,制定系统模块间通信协议。完成GPS模块和文件管理模块的设计与实现：GPS模块遵循NMEA-0183协议标准规范,采集经纬度、UTC时间等路测信息,除此之外该模块为系统提供时钟基准,是保证系统内部控制时序有序运行的基础；文件管理模块为系统输出数据信息存储提供服务,通过该模块系统得以在SD数据卡中完成文件创建、文档创建、字节写入等文件管理操作,该模块是系统内信息采集与信息存储的桥梁。同时,文件管理模块是系统采集信息输出窗口,通过输出数据可验证系统功能是否满足预期设计。系统实测结果满足预期设计,验证了本设计方案合理有效,开发模块稳定可靠,系统能够自动记录并存储多制式网络空口信息,达到无线网络测试的要求。
[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.
