The invention relates to a control method for realizing continuous alarm of a railway crossing. When a train set cuts a magnetoelectric sensor in the forward direction, a proximity alarm controller stops voltage output, an alarm latching relay loses magnetism, and a second group of contacts of the alarm latching relay cuts off a downlink control power supply of a host to start proximity alarm; theproximity alarm controller recovers power output 5s after the train passes through the magnetoelectric sensor, and at the moment, three excitation circuits of the alarm latching relay are disconnected; when a crossing annunciator is in an open state, a second group of contacts of the crossing annunciator is disconnected; when the crossing section is in an idle state, a fourth group of contacts ofthe crossing section is disconnected; and when the train set arrives at the crossing and occupies the crossing section, the fourth group of contacts of the crossing section is communicated with the excitation circuits of the alarm latching relay, self-locking is realized through the first group of contacts of the crossing section, and a closing latching relay controls the circuit to recover. Continuous automatic alarm of a rail circuit is realized.
本发明涉及一种实现铁路道口连续报警的控制方法,当车列正向切割磁电传感器,接近报警控制器控制电压停止输出,报警闭锁继电器失磁,报警闭锁继电器的第二组接点切断主机下行控制电源启动接近报警;车列过磁电传感器5s后接近报警控制器恢复控制电源输出,此时报警闭锁继电器的三路励磁电路均已断开;道口信号机在开放状态,道口信号机的第二组接点断开;道口区段处于空闲状态,道口区段的第四组接点断开;待车列到达道口占用道口区段时,道口区段的第四组接点连通报警闭锁继电器的励磁电路,再由道口区段的第一组接点实现自锁,接近闭锁继电器控制电路恢复。本发明实现轨道电路连续自动报警。
