在各种知识抢答竞赛中,通常会遇到这样的一个问题：人工抢答容易犯错造成争议,辅助的抢答系统使用成本高、配置复杂、扩展性差等。市场急需一种使用成本较低,简单易用的抢答系统。该文设计和实现的现场抢答系统基于Android平台开发,利用无线直连（Wi-Fi Direct）技术,可以把各种无线智能设备接入系统。由于Android的流行和Wi-Fi设备的普及,系统除了保证抢答的准确性,易用性和通用性也优于各种有线的抢答系统。本系统可以兼容各种主流的Android智能设备,无需专门的硬件支持,使用成本比专门的硬件抢答系统更低。
There are some usual problems on all kinds of knowledge contest：it＇s prone to error that determining the order of responder by manual;some Responder Systems are expensive、hard to deploy and extend。It＇s necessary to find some systems with low cost and easy to use.In this paper,a new Responder System is designed and implemented which based on Android operation system.It can connect all kinds of wireless smart devices with the help of Wi-Fi Direct technology.Duo to the popularity of Android and Wi-Fi the system is easier to be used and deployed than other wired Responder system in addition to ensure the accuracy of the order of responder.The system is compatible with a variety of Android start devices.It＇s cost less than other Responder System with dedicated hardware.
