无线网络实时监测系统
|
摘要
路测工作是无线网络优化的主要组成部分,常规路测方法需要占用优化技术人员很多时间和精力体力去获取测试数据,而不能集中于问题的发现和深入分析,以及提出解决措施。实时监测系统是将小型化专用路测单元放置在社会车辆上,通过无线数据传输方式,实时将测试数据传送到后台系统,进入海量数据库。网络优化人员利用后台系统及相应分析软件工具,对无线网络状况进行显示和分析,节省了技术人员的大量重复性工作,极大的提高了网络优化工作的效率。
本文以实时监测系统的核心部分——车载测试终端的功能、硬件和软件的设计与实现为主。按照实际需求对系统中的车载测试终端的功能进行了详细的分析,并根据实际情况确定硬件组成和软件工作流程,最终完成了车载测试终端的设计与实现。结合设计方案详细阐述了软、硬件设计和实现过程。对无线数据传输的实现方法做出详尽说明。针对开发过程中的典型问题,给出了解决方法。
对几种无线数据传输方式比较之后,设计方案选用CDMA网络作为数据通信平台,发挥了CDMA数据传输的优点,提高了数据传输率,增强了实时性,增大了传输流量,降低了通信费用。设计中采用功能强大的控制器Rabbit2000,其具有丰富的串行端口、通用I/O脚和库函数,降低了软硬件开发难度。中兴(ZTE)的CDMA模块MG815+作为无线Modem,同时负责采集CDMA网络质量参数。GSM网络质量参数由SIM300C采集。另外,还配以GPS数据采集模块E531及液晶模块等。
除车载测试终端外,实时监测系统还包括功能强大的后台管理、分析系统,其工作包括数据的接收,大量数据的清洗、归纳、抽样、统计分析,地理化显示等。
网络优化是一项复杂而长期的工作,实时监测系统在其发展中必将发挥越来越重要的作用。
DT is a composition importantly in optimization of mobile network. The regular ways of DT make the technicians to spend much more time and energy to get the testing data, but not be able to focus on finding out the problems in network, and analysis it deeply, with providing the way of resolving. Real-Time Monitoring system is such a system that the miniaturization special DT unit is placed in the social vehicle to transmit the testing data to the background system to enter into a massive database by wireless data transmission. It greatly saves repetitive work of the technicians and improves the efficiency of network optimization by displaying and analysis the status of wireless network using background system and corresponding analysis software tools.
This paper focuses on the core part of the Real-Time Monitoring system—the functions and the hardware and software designing and implementation of the Vehicle Terminal. Regarding practical demand and situation, a detail analysis is carried out on the functions of the Vehicle Terminal and hardware and software flow chart are determined and the design and implementation of vehicle terminal are finished perfectly. The hardware and software design and implementation process are expounded in detailed. The implementation of wireless data transmission is illustrated in detail. Finally, the typical problems and the solutions are presented.
After the comparison of the wireless data transmission methods, our design adopts CDMA network as the data communication platform which takes full advantages of CDMA. Such as increasing the data transfer rates, enhancing the capacity of real time, increasing the transmission flux, and reducing the communication charge. The use of mighty function module Rabbit2000 which provides rich serial ports, general 10 ports, and lib function makes the work of the hardware and software easy. ZTE's CDMA module MG815+ works as the wireless modem. It also collects the CDMA network quality parameters. The GSM network quality parameters are collected by SIM300C module. The system also includes GPS data collection module E531 and LCD module etc.
Except the Vehicle Terminal, it also includes a powerful background management and analysis system in the Real-Time Monitoring system. Its function includes data reception, massive data cleaning, summarizing, sampling, statistical analysis, and geographic displaying.
Optimization of mobile network is a complex and lasting work. Real-Time Monitoring system is playing an increasingly important role in its development.
