Sports track events are the major events in sports competition and have been the major ways of peoples participation in sports. As technology advances and managerial concept changes, the digitalization, intelligentization and automation of management has become an unavoidable trend for track events. As a major component of track events managerial automation, automatic circle-counting system has been attached great importance by the sports circle. Based on these developmental changes in track events management, this paper analyses the core part of automatic circle-counting system in track events, that is the research and design of information processing, with special focus on the analysis of its influence on electronic circuit, processing module and data base. This research aims to ;perfect the design of information processing with improved function, rationalized interface design, solid framework and simple operation so as to provide scientific and efficient service to track events and promote actively the IT level of track events management.
