乒乓球比赛模拟机的设计

北京理工大学珠海学院 2020 届本科生毕业设计乒乓球比赛模拟机的设计 乒乓球比赛模拟机的设计摘 要乒乓球运动是我国的传统运动，深受着许多人的喜爱。现如今，人们的生活节奏加快，在日常生活中，人们的时间大都是碎片化的，同时传统的乒乓球运动还受到场地与环境的限制，因此本设计将乒乓球运动与电子技术相结合，主要以74LS194 双向移位寄存器和发光二极管作为基础来模拟乒乓球的运动轨迹，使用74LS74D 触发器和按键控制开关组合，控制驱动整个电路，为本设计的核心部分，用于模拟球拍接发球，球到指定位置时，及时按下按键代表击球成功，否则对手得分。最后通过 74LS160 十进制计数器与数码管组合显示双方的得分情况。关键词：乒乓球比赛模拟器；74LS194 双向移位寄存器；74LS74D 触发器；74LS160十进制计数器；北京理工大学珠海学院 2020 届本科生毕业设计北京理工大学珠海学院 2020 届本科生毕业设计Design of table tennis simulatorAbstractTable tennis is a traditional sport in China, which is loved by many people.Nowadays, the pace of people's life is speeding up.The most time of people are fragmented in daily life.At the same time, traditional table tennis is also limited by the venue and environment.Therefore, this design combines table tennis with electronic technology.In order to simulate the movement track of table tennis，it mainly uses 74ls194 bidirectional shift register and LED.And it uses 74ls74d trigger and key control switch to control and drive the whole circuit, which is the core part of this design.It is used to simulate the receiving and serving of racket.When the ball reaches the designated position, pressing the key in time represents a successful stroke.Otherwise,the opponent will score.Finally, the score of both sides is displayed by the combination of 74ls160 decimal counter and nixie tube.Keywords: Table tennis game simulator ； 74ls194 bidirectional shift register；74ls74 data flip-flop；74ls160 decimal counter；北京理工大学珠海学院 202...
