铁路信号连锁控制动态继电器检测仪的开发

Development of Test Instrument for Railway Signal Interlocking Control Dynamic Relay

以机械特性、电气特性和动态特性为研究对象,研究开发集JARC-1000型和JSDXC-1700型铁路信号连锁控制动态继电器便携式自动检测仪。以微型单片机为控制核心,软硬件均采用模块化的设计方法,译码选板和译码选接点电路的设计有利于系统的扩展。系统软硬件设计均充分考虑系统干扰,经实测表明,系统工作稳定,测量精度满足要求。

Takes the mechanical feature, electrical characteristic and dynamic performance as studying objects, studies and develops the portable automatic test instrument of railway signal interlocking control dynamic relay which combined JARC-1000 and JSDXC-1700. The micro single-chip is the controlling center; and the design method of the software and the hardware are all using the module design; the electrical design for coding and decoding plate and connector is good for system expending. The system hardware design is also taking the consideration of system disturbance; the actual testing shows that the system is stable and the precision is under the requirement.
