本文简述IRIG标准的演变、国内频分制遥测系统的发展过程、频分制遥测系统的发展趋向和频分制遥测系统如何与计算机配合。频分制遥测系统与计算机配合方案有两种其一是继承现有设备,加上模数变换器与计算机接口电路,再用计算机进行数据处理;另一种是以数字滤波器为中心的可调数字鉴频器,它能同时解调频分制中所有的副载频通道,它的输出是能与计算机兼容的数字格式。 This article briefly describes the evolution of the IRIG standard, the development of the domestic frequency division telemetry system, the development trend of the frequency division telemetry system and how the frequency division telemetry system cooperates with the computer. Frequency division telemetry system and computer with the program in two ways First, the succession of existing equipment, coupled with the analog-digital converter and computer interface circuit, and then use computer data processing; the other is based on the digital filter can Adjust the digital frequency discriminator, it can demodulate all the subcarrier frequency channels in the frequency division at the same time, its output is a computer compatible digital format.
