摘要:
为了解决以往使用单片机或单核数字信号处理(DSP)芯片的计轴系统无法满足高速列车计轴信号处理的问题，本文提出使用现场可编程门阵列(FPGA)为核心芯片处理列车轴信号。根据FPGA运行速度快、工作效率高(并行执行)、可重复编程和时序实现能力强的优点，设计完成了一套FPGA计轴信号处理系统。通过实验和实际验证表明：该FPGA计轴处理系统具有适应性强、可编程性强、精度高、安全可靠等突出优点，解决了高速列车计轴信号无法处理的问题。
Abstract:
In order to solve the problem that the axle counting system using single-chip microcomputer or single-core digital signal processing (DSP) chip cannot meet the requirement of axle counting signal processing of high-speed trains, we propose to take the field programmable gate array (FPGA) as the core chip to process axle signals of a train, realizing the axle counting signal processing system. FPGA is fast, high-efficiency (parallel execution), and has repeatable programming and strong timing implementation ability. Experiments and practical verifications show that the FPGA axle counting processing system has outstanding advantages such as strong adaptability, high programmability, high accuracy, safety and reliability, etc., and has solved the problem that the axle counting signal of high-speed trains can not be processed.
