The Design And Implementation Of Passenger Car Axle Temperature Analyzing System

With the continuous development and progress of society,railway transportation has gradually become the most frequently used vehicle in many modern transportation.In the 21st century information technology apply to every walk of life generally,China railway career also make full use of information technology and accelerate development.The train speed is improvement constantly,and provides a convenient for passengers and cargo transport,but the running security of train is much concerned. In order to avoid the hot cutting axle and other accidents,the establishment of a complete axle temperature analyzing system is an important measure.According to the actual demands of Chengdu Railway Bureau axle temperature analyzing,the thesis effectively combines with the principles of software development,and discuss the system analysis,design and implementation, then develop the Axle Temperature Analyzing System based on PowerBuilder 9.0 platform.First of all,thesis outlines the research background and significance of this topic,and expected to have a whole recognition of the system.Secondly,start with business process of this system,analyse and design the system function of each module in detail,then draw the main use case model and business activity diagram. Combine with actual situation and database theoretical knowledge based on system analyzing,and design the system dabase.In addition,design the system security by managing role.Finally,explain the principle,procedure and method of implementation in each the main system function module in detail,then along with the key codes and relevant charts which can illustrate.The system meets the depot's demands of axle temperature analyzing work,and also enhances the unified management of data.Currently the system has applied to workshop pratically which indicates that the system has achieved the design aims and improved work efficiency,and it has reliable performance,the application effect is good.
