一种全电子化的道岔控制模块的研究

The Study of an All-Electronic Switch Control Module

本文用全电子化的道岔控制模块取代了由安全继电器构成的电路,采用模块化电子电路实现三相交流转辙机的驱动电路和表示电路。文章详细论述了道岔控制模块的设计、驱动电路设计、表示电路设计和故障-安全原则的实现方法;道岔控制模块全电子化为全电子计算机联锁奠定了坚实的基础。

The all-electronic switch control module replaces the circuit composed of safety relay,and it adopts a modular electronic circuit to realize the drive circuit and display circuit of the three-phase AC switch.In this paper,the design principle of the switch control module,the design principle of the drive circuit,the design principle of the display circuit and the implementation method of the fail-safe principle are discussed in detail.The all-electronic switch control module lays a solid foundation for the all electronic computer interlocking.
