Abstract

Abstract: According to the operation characteristics and development trend of DC switch machines in railway signal systems, a nodeless DC switch machine drive module is designed. This module can ensure the safe driving and acquisition of the DC switch machines without relay nodes, and monitor the operation and position status of the switch machines in real time. This module is designed based on the "fail-safe" principle, demonstrates stable performance and strong practical value, and will play an important role in trackside controllers in the future.

Key words: DC switch machine, trackside control, drive circuit, acquisition circuit

摘要： 针对铁路信号系统中直流转辙机的运行特点和发展趋势，设计出一种无节点直流转辙机驱动模块。此模块可保证在没有继电器节点的情况下对直流转辙机进行安全驱动及采集，并实时监测转辙机的运行及位置状态，此模块采用“故障-安全”原则进行设计，性能稳定，具有较强的实用价值，将在未来的轨旁控制器中发挥重要作用。
