基于单芯电缆传输的多转辙机拉力测试仪设计

Design of Multi Point Machine-Traction Tester Based on Single Core Cable Transmission [HS)]

摘要:

高速道岔转换时需要采用多转辙机牵引,详细给出了便携式多转辙机牵引道岔转换阻力测试仪的设计过程;该测试仪以NXP公司的ARM7微处理器LPC2214为硬件核心,以uC/OS-II实时操作系统为软件核心,测试仪主机和各传感器采用树形拓扑结构的主从机方案,使用单芯电缆传输技术,将测试仪主机与各传感器联接到一起,完成的同时对1~6台在轨转辙机的牵引力的测量和为各传感器供电；实测表明,测试仪完全满足设计要求,适合铁路电务人员对多点多转辙机牵引道岔转换阻力进行在轨测量,满足实际要求。

Abstract:

The multi point machines can change the high speed railway turnout. It describes the process of the design of the portable tester of multi point machine-traction system. The hardware platform of the tester is based on the LPC2214 chip of micro controller with ARM7 core and the software platform is established in the μC/OS-II real-time operating system. The tester master machine and the sensor slave machine makes up the tree topology and transmits through single core cable. The single core cable not only supplies power for sensors, but also transmits data between the master machine and the slave machine. According to the practical application, the tester could completely fulfill the design requirements. It is suitable for testing the multi point machines in the multi traction system.
