在传统的ECP制动系统的基础上,采用Microchip公司的主控芯片DSPIC30F6011A和Echelon公司的电力线智能收发器PL3120,对重载列车ECP制动系统头端单元(HEU)进行了研究。结合国内外对ECP制动系统的研究经验,对头端单元(HEU)的硬件和软件进行了分析和设计,同时分析了头端单元(HEU)的运行试验和故障监测情况。
Based on the traditional ECP braking system, the head end unit (HEU) of ECP braking system for heavy haul trains was studied based on DSPIC30F6011A, which is Microchip’s main control chip, and PL3120, an Echelon power line intelligent transceiver. Based on the research experience of ECP braking system at home and abroad, the hardware and software of head unit (HEU) are analyzed and designed. At the same time, the running test and fault monitoring of head unit (HEU) are analyzed.
