Abstract

The utility model discloses a digital indicator for a railway approach auxiliary signal stock way, and relates to the field of railway approach auxiliary signals. The railway station entering auxiliary signal track digital indicator comprises a track digital indicator unit. The digital indicator for the auxiliary signal track of the railway station entering is characterized in that a turnout position sensor is arranged at the switch rail of a positive track and a side track, whether the track change action is in place is monitored in real time, signal transmission is carried out, a programmable logic controller is arranged in a digital indicator main body for the track, input signals from a photoelectric sensor in a annunciator unit and the turnout position sensor on the track unit are received, and synchronous judgment logic is executed. The switch position sensor compares the time sequence and the state of the two signals through a preset program, and if the allowable time difference is exceeded or the state is inconsistent, the switch position sensor triggers a fault.

Description

Digital indicator for auxiliary signal stock way of railway station approach Technical Field The utility model relates to the technical field of railway approach auxiliary signals, in particular to a railway approach auxiliary signal stock way digital indicator. Background The railway approach auxiliary signal is key equipment for ensuring that the train safely enters the station, and the speed and the path of the train are regulated by combining various signals. The auxiliary signal of railway entering the station is cooperated with various annunciators such as duplicate display, guidance, shunting and the like, and is combined with the combined display of yellow flashing, double yellow and the like, so that the safe adjustment of the path and speed of the train in the complex station environment is ensured. The driver needs to strictly follow the signal instruction and combine the speed limit requirement to finish the operation of getting into the station, but in the prior art, only the signal lamp is controlled to send out the instruction to control the train to perform the operation of getting into the station, but when the switch rail is in the junction of the turnout, the train cannot stably get into the station when the switch rail cannot be adjusted in place, but the signal lamp cannot judge whether to realize track switching, and when the train continues to get into the station, the condition that the train cannot stably get into the station easily occurs, and accidents occur due to violation or out of control, so we propose a railway approach auxiliary signal stock digital indicator.
