LAN by virtue of their superiority in the industry have long been a widespread application. The traditional mode of general knowledge contest mechanical electronic trigger button to answer questions was the priority, equipment installation and maintenance complex, a more general in nature and network systems need of the development of competition. LAN competition system is based on LAN technology to text and graphic content-based modernization of general knowledge contest software. The integrated design specification of the system development background, significance and the development of ideas, development of the system used in key technology, the system feasibility analysis, demand analysis and design methods for a comprehensive description, Meanwhile the system functional modules for the realization of the system description. The system of low-cost, the installation of mobile convenience, versatility, and and the mobilization of more participants, especially young people, enthusiasm for the contest, ease of application and worth promoting.
