Information system for satellite monitoring of agricultural machinery using Wialon IPS communication protocol

Abstract

The article is devoted to the urgent problem of developing an information system for monitoring the location and condition of agricultural machinery as part of the introduction of precision agriculture technologies in the activities of agricultural companies. It discusses the general principles of organizing the interaction of system components, such as GPS trackers, a web server and a client computer, defines the main stages of interaction and describes the communication protocols used at each stage. Special attention is paid to the consideration of the packet structure of the Wialon IPS protocol, which is used to transmit data on coordinates and other technical parameters. For this protocol, several methods have been proposed for parsing the contents of packets to extract useful information from them, both using standard functions of programming languages and using regular expressions. To protect the transmitted data, a two-way authorization algorithm is developed, its scheme is given and the main stages are described. The article also presents the approaches to the implementation of parallel processing of connections from a large number of GPS trackers to increase the overall efficiency of the system.
