Real-Time Wireless Network Monitoring System

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.
