基于无线红外通讯的新型球场换人牌设计

The design of new substitution-plate based on wireless infrared

本文设计了一种新型的基于无线红外通讯的电子式换人牌,通过无线红外通讯模块与单片机接口的应用,使得换人牌的显示信息由手操器无线传达。本文分析了红外通信原理,利用串行通信接口进行红外收发。设计硬件电路及相配合的软件程序,设计了震荡发生器,应用X5045进行数据存储和看门狗,应用74HC595进行数据的串入并出等。经试验证明可能够提高执场裁判员的工作效率,降低显示信息出错的几率。

This article describes a new type of wireless Infrared communications based on the change of electronic licensing,through wireless Infrared communication interface module with the application of single-chip,making the display of a license change hands Operator information from the wireless message.This paper analyzes the principle of infrared communication,the use of serial communication interface to the infrared transceiver.The hardware circuits and matching software program are designed,shock generator is designed,X5045 is used to storage data and watchdog,the application of 74HC595 is used transform serial data into parallel data and so on.To improve the enforcement field in order to judge the efficiency of the display information to reduce the chance of error.
