A vpx-based satellite communication data processing module

Abstract

The invention discloses a satellite communication data processing module based on VPX, and belongs to the field of satellite communication. The system comprises a channel board and a service board, wherein the channel board comprises a first PowerPC processor, a first FPGA, a first RS485 interface chip, a modulation module and a demodulation module, and the service board comprises a second PowerPCprocessor, a second FPGA, a second RS485 interface chip, a synchronous / asynchronous output processing module and a voice processing module. The satellite communication data processing module is divided into the channel board and the service board, and distributed processing of channels and services is achieved. The number of the channel boards and the number of the service boards can be flexiblyconfigured according to actual service requirements, hot backup of channel access and service processing in a resource pool mode is achieved, and universality, flexibility and reliability of the wholesystem are effectively improved.

Description

technical field [0001] The invention belongs to the field of satellite communication, in particular to a VPX-based satellite communication data processing module. Background technique [0002] The traditional satellite communication data processing module is realized by parallel bus architecture, which has low integration, large space occupation and insufficient interface expansion capability. With the continuous development of current integrated circuit, processor technology, and programmable logic technology, the traditional parallel bus can no longer meet the communication requirements of large bandwidth and high speed in the field of satellite communication. [0003] VPX is a next-generation advanced computing platform standard formulated by VITA to meet the requirements of high reliability and high bandwidth in harsh environments. Applying VPX to the satellite communication data processing module can greatly improve the efficiency of satellite communication. Contents...
