摘要:

针对目前弹载遥测系统对PCM编码器提出的通用化应用需求,提出了一种基于现场可编程门阵列的通用化PCM编码器;该方法以软件为主的信号处理方式代替硬件处理,采用Verilog HDL语言和模块化的设计思想将编码器的各功能模块集成在单片FPGA中,通过功能模块的积木式组合和参数配置实现了对被测弹箭系统的采集编码;仿真测试结果表明该编码器满足绝大多数弹箭遥测系统的参数测试要求,在弹箭遥测系统中飞行试验结果表明该编码器在全弹道飞行过程中工作稳定可靠,该编码器实现了通用化的要求。

Abstract:

For the universal requirements of of missile-borne telemetry system. It proposes a universal PCM encoder based on FPGA . A signal processing method basd on software processing instead of hardware,applies verilog HDL language and modularization, down-top design ideas, integrates the encoder's functional modules in the single chip FPGA. It can encode telemetry datas by putting functional modules together and configuring parameters. Simulation results show that the coder parameters meet the test most telemetry system requirements, Telemetry system flight test results show that the encoder work stable and reliable, this encoder has strong universality. 
