| 摘 要： | <正> 一、引言在具有数据压缩功能的遥测系统中,某一采样时刻的数据是否需要传输是随机的,这就有可能导致传输帧的不等长性,给接收端的同步造成了一定的困难。为了与原有的接收设备兼容,通常将经过压缩处理后的数据在形式上排列等长的传输帧,来解决帧同步问题。这种等长的压缩帧所包含的实际内容却千差万别,必须使用计算机进行分路、解压后,才能恢复

| Abstract: | Microcomputer Telemetry data receiving and processing system (MTDRPS)mainly consists of a BCM-1 microcomputer system and a single board computer with 8 bits word length. With the receiving devices of the ground stations, MTDRPS can receive and process the compressed telemetry data. The system has two main features:
1. The data receiving buffer is used and the serial telemetry data receiving and parallel data storing are processed by two microcomputers respectively.
2. By using the software method the synchronism was performed |
