Software Design Of Real Environment Digital Games

Based on the concept of real environment digital game, in the thesis we designed a set of network and voice-controlled model tank battle game system with integrating computer network, voice recognition technology, radio frequency, ultrasonic positioning, infrared communication technology and so on. The system is now complete the work about the battle of model tanks.We first introduce overall structure of the real digital game system and the key technology applied in the software design. Then we detail the part of the software. Software system includes three parts: 1. Joystick control. Mainly realize the precise control process software of model tanks. 2. Design and realization of ultrasonic positioning subsystem. This subsystem is the core of entire system software. In initial work basis we add new mathematical theory argumentation which makes reference point selection reasonable. In algorithm design, we introduce condition number concept in pan letter. Condition number will make error generated by reference point selection control in project extent permitted. Finally, we make C# realization of ultrasonic positioning. For positioning error, we conduct matlab simulation. According to experimental results, positioning accuracy reaches±5cm, meeting project requirements. 3. Game interface software realization. In previous basis design, we add more functionality which makes closer reality enhanced entertaining.Now, the entire project research has been completed adopted Tianjin teach CST Expert Group acceptance. We will do further study to make ultrasonic positioning accuracy raise to±1cm.
