摘要
红外光是有许多优势的通信媒介 ,红外通信 Ir DA标准是目前 IT和通讯业普遍支持的近距离无线数据传输规范。本文介绍了红外通信 Ir DA标准的内容以及它的物理层协议 ,脉冲调制的必要性 ,不同传输速率下不同的脉冲调制方式 ,连接建立协议层的帧结构。给出了符合Ir DA标准的芯片 TOIM32 32和 TFDS450
Infrared is a convenient communicatio n medium that has many advantages. IrDA association has a membership of over hun dreds of companies in the computer and telecommunication industry, including com ponents, hardware, software and adapter manufacturers. This paper introduces IrD A standard and the physical layer of it in detail: the necessity of pulse modula t ion, the different modulations and frame formats at different data rates. We pr e sent the application of the IrDA TOIM3232 and TFDS4500 in testing experimental e quipment under the high voltage environment.
