【摘要】 红外无线通信技术提供了一种低成本、短距离、高速率的无线通信方式，使用简单的收发器就能实现高效率的无线互连。IrDA红外数字协会提出的IrDA红外通信协议为全球数千万带有红外数据接口的设备的互连提供了基础。 本文在学习整理红外数字通信原理知识和IrDA通信协议的基础上，以智能仪器数据通信为目的，研制了一种基于单片机的通用红外通信接口模块，它支持IrDA协议，采用串行输入输出，可以做为附加通信模块方便地集成到各种设备和仪器仪表中。本文详细地介绍了该模块的硬件与软件设计，IrDA协议状态机的实现，以及实验室中做为彩电白平衡自动测试仪红外通信接口的方案，最后本文还提出了基于通用红外通信接口模块的一些应用设计。更多还原

【Abstract】 Wireless Infrared Communication Technology is used for low-cost, short-range, high-speed wirless digital communication. With very simple transceivers, high-efficient Infrared links can be achieved. IrDA protocol established by Infrared Data Association has become the standards for millions of devices to communicate mutually.In order to solve the communiction between Intelligent Instruments, after studying the basic theory of Wireless Infrared Communication and the IrDA protocol, a General Infrared Communication Interface (abbr. GIRCI) based on the MCU is developed in this paper. GIRCI is up to the IrDA standard, supporting the UART I/O transmission, and can be integrated with devices and instruments as an additional module easily. In this paper, the detail scheme of hardware and software development is discussed, including the development of the state machine of IrDA protocol and the application of using GIRCI in the White-balance Measurement Instrument. Finally, some more applications based on GIRCI are mentioned.更多还原
