我公司针对铁路道口防护应用的特点，基于DX3型铁路道口信号设备设计了LCX-Ⅱ型铁路道口控制系统。列车接近信息的采集和确认是整个系统的技术核心和能否稳定运行的基础，该系统采用国铁成熟系统的JZXC-480型交流轨道电路或25Hz相敏轨道电路对列车接近信息进行采集，实现列车接近道口自动报警及道口警报机、栏木机、遮断信号等设备联控，保证道口通行安全。通过远程控制系统，实现工作人员对道口的远程监测和控制。

LCX-Ⅱ型铁路道口控制系统是基于DX3型铁路道口信号系统设计，能够长期、有效的在铁路道口内实现火车接近时的安全防护。

According to the characteristics of the railway crossing protection application, based on the DX3 type railway crossing signal equipment our company designed the LCX - type Ⅱ railway crossing control system. Train approaching information acquisition and confirmation is the core technology of the whole system and is the basis of stable operation, the system adopts the mature system of AC track circuit JZXC - 480 or 25 Hz phase sensitive track circuit on train approaching information acquisition, to realize automatic alarm and the joint control of crossing warning machine, barrier machine, interrupt signal devices, and ensure the safety of the crossing traffic. The remote monitoring and control of the crossing are realized through the remote control system,.

LCX - Ⅱ type railway crossing control system is designed based on the DX3 type railway crossing signal system, and is a long-term and effective protection system for the railway crossing.
