铁路信号电源是专门给列车运营信号供电的系统,其可靠性要求非常高,因此,对铁路信号电源的监视和控制十分重要,本文在分析现有铁路信号电源存在问题的基础上,探讨了信号电源监控系统的功能需求,并结合数字信号处理器(DSP)的特点,研究了基于双DSP的铁路信号电源监控系统的硬件及功能设计。
The railway signal power supply is a system dedicated to supplying signals to train operation signals. Its reliability requirements are very high. Therefore, it is very important to monitor and control the railway signal power supply. Based on the analysis of the existing problems of railway signal power supply, Power supply monitoring system function requirements, combined with the characteristics of digital signal processor (DSP), study the hardware and function design of railway signal power monitoring system based on dual DSP.
