论文 基于PTR80000的无线智能抢答器设计
摘 要: 本文给出了一种基于PTR80000的多路无线智能抢答系统的设计方案。系统通过自定义通信协议，实现带有载波侦测的双向同步通信。由主机对从机的绝对访问权限，可灵活实现抢答否决控制，能够按时序区分作弊抢答行为以保证抢答过程中的公平性。通过系统复用数据传输功能，实现了客观试题的无线作答。
Abstract: This paper presents a PTR80000 based on the multi-channel wireless smart Responder system design. Custom communications system, through an agreement with the carrier detect achieve the two-way synchronous communication. From the host machine from the absolute access, flexibility to achieve Responder veto control, timing can differentiate by cheating Responder Responder act to ensure the fairness of the process. Through systematic reuse data capabilities to achieve the objective of the wireless answer questions.
