Design And Implementation Of Improved Digital Game In Real Environment

The project of digital game in real environment is one of the innovation fund projects of Tianjin, and the Model-Tanks Versus-System is one fundamental and important part of the digital game in real environment .The Model-Tanks Versus-System includes the following details.Players can send commends through the handle of the server-side to control tanks’movements and to complete versus in two groups. At the same time the server-side counts the scores and the results for two groups. Then show tanks’position and coordinate through the positioning device in real time. The system can show the position of tanks in accurately. This paper describes the improvement program which improves the performances of the overall system .And discussed in detail some advanced modern technology used in the system such as wireless LAN technology, ultrasonic positioning technology, and EDA technologies and so on, and elaborated on the implementation of modules.1. Improvements of hardware circuit .Replace the CPLD and wireless communication module in hardware circuits and set up the wireless LAN through the router, PC and Matchport in the new hardware circuit conditions.2. Improvements of communication protocol on server-side. In order to improve the performance of the system and make the system more real-time. Change the TCP communication protocol to UDP communication protocol and compare the communication data through network packet. Demonstrated using UDP protocol can really improve the system in real time.3. Improvements of ultrasonic positioning. The existing ultrasonic positioning system is frequency- ultrasonic positioning which is not only complex, but also caused great delay error. Improved ultrasonic positioning is using ultrasonic reflection method which is faster than the fomer one.
