IMPLEMENTATION OF A TRANSPORTATION MONITORING SYSTEM BASED ON CLIENT-SERVER ARCHITECTURE

This paper discusses the main stages of development of an automated transportation monitoring system. The aim of the work is to optimize logistics management processes by developing such a system. During the design and development of the system, the subject area and object of automation of the transport transportations monitoring system were considered and analyzed in detail. The features of existing analog systems were studied. The choice of technologies used in the development of the system was substantiated. The system architecture was developed and the design templates used were analyzed. When designing the architecture of the transportation monitoring system, a standard three-tier client-server architecture was used as a basis. The software for the server and client parts was developed. The server and client parts of the system are developed using the C++ programming language and the Qt framework. The server part is software deployed on the Ubuntu Linux operating system, which provides processing of TCP requests from clients, work with the PostgreSQL database, as well as APIs for retrieving data from the system. The client part is an application for an Android device inside the vehicle that transmits coordinates and events to the server via a TCP connection. For convenient presentation of data from the server side API, a web application was also developed that dynamically displays vehicle information using the JavaScript language and the jQuerry library. Vehicles and their routes are displayed in real time on the website page using the Leaflet library. The result is a comprehensive system that provides monitoring of transportation, processing of events occurring during transportation, convenient storage and display of this data. The system proved its reliability and resistance to loads during testing.
