Design Of Traffic Weather Real-time Monitoring And Data Management System

Function of highway traffic is more and more important in national economic construction. However, severe weather effects on road traffic safety has increasingly become the focus of attention.Meteorological elements must be continuously and automatically observed, and also the data observed should be quickly and efficiently stored, managed, analyzed, processed and shared. With regards to this, according to the actual demand to meteorological data management from manual to computer intelligent of domestic traffic weather monitoring job currently, a suit of real-time traffic monitoring and meteorological data management system is designed for weather monitoring and warning of traffic decisions. Main contents are as follows.Client/Server architecture were selected. SQL Server2000 is selected as the system's database platform. The monitoring data are audited and counted in real-time, stored according to their sort, and the indexes are created on the tables, so that the users can access weather data quickly, and users, tablespace and datafile of database are managed. In Window XP, Delphi7.0 is utilized for designing and developing the system module.The connection between application program and the database of the central station is completed using ActiveX Data Objects (ADO). A method which combines the use of Delphi and Office software and uses the component of Timer in Delphi is determined to make the meteorological manage intelligently.The paper analyzed the function of this system, module, system processes and so on. And the actual implementation of business and related technology, for example, verified the feasibility of this solution.This system achieves real-time reception of meteorological data, the check of data and the storage of meteorological data, data processing and analysis; provides a search function including the conditions of the show of historical data, and using such report, curves for visual display; to achieve a data backup, restore and other functions.According to recent historical data, using time series and neural networks to achieve short-time forecast of meteorological elements, to provide support services for the early warning. Based on the predicted data for timely and accurate real-time weather alarm, such as high temperature, heavy rain and sandstorms, etc., and for decision makers, so that the losses caused by bad weather to a minimum.First, the paper describes traffic weather industry in the world and domestic develpoments; Second, the paper introduces related technology systems involved; then, it recommends the details of real-time traffic monitoring and meteorological data management system design and development process; the next two chapters, describes the data processing related content:single station meteorological elements and weather forecasts warning. Introducing the neural network BP algorithm and BP network, BP network design, training, and combined with neural network time series prediction. Single-station weather forecast provides the basis for early warning.Finally, the paper summarizes the topics discussed and points out the follow-up should strive to improve and areas for improvement.
