基于两级校验码的数传分系统的排故系统及其排故方法
摘要：
本发明提供了一种基于两级校验码的数传分系统的排故系统及其排故方法，基于两级校验码的数传分系统的排故系统包括数据处理器、固态存储器、调制器、固态放大器、地面接收设备，固态存储器、调制器都与数据处理器连接，固态放大器与调制器连接，地面接收设备与固态放大器连接，数据处理器包括AOS组帧模块、信道编码模块、一级CRC校验码和二级CRC校验码。本发明无需另外的地面设备，实现方式简单容易，可以便捷得定位误码发生的环节。
摘要（英）：

The invention provides a troubleshooting system and method of a data transmission sub system based on two stages of check codes. The troubleshooting system of the data transmission sub system based on the two stages of check codes comprises a data processor, a solid-state memory, a modulator, a solid-state amplifier and ground receiving equipment. The solid-state memory and the modulator are both connected with the data processor, the solid-state amplifier is connected with the modulator, and the ground receiving equipment is connected with the solid-state amplifier. The data processor comprises an AOS framing module, a channel coding module, the first stage of CRC check code and the second stage of CRC check code. By means of the troubleshooting system and method of the data transmission sub system based on the two stages of check codes, additional ground equipment is needless, the implementation mode is simple and easy, and thus error code occurring links can be positioned conveniently and rapidly.
