AI Technical Summary

Technical Problem

Since the ATO system sends the ATO operation plan for a long period, it is impossible to guarantee the receipt of the ATO operation plan within each full docking cycle, and it is impossible to automatically calculate the departure countdown when the train is fully stopped, affecting the efficiency of the automatic operation of the train.

Method used

By obtaining the ATO operation plan containing the departure time of the target stop, it is determined whether it is received within the train's full stop cycle. If received, it is determined that the current ground moment in the ATO operation plan is the full stop time; if not received, the full stop time is determined based on the first data processing cycle and the full stop cycle of the ATO operation plan received, and the departure countdown is calculated.

Benefits of technology

Each time the train stops completely, the departure countdown can be accurately calculated, ensuring that the on-board system can automatically control the opening and closing of the train doors, and improving the efficiency of the automatic operation of the train.

Abstract

The invention discloses a method and a device for calculating departure countdown, relates to the technical field of train control, and mainly aims to improve the automatic running efficiency of a train. According to the main technical scheme, the method comprises the steps that an ATO operation plan containing the departure moment of a target stop station is obtained; judging whether the ATO operation plan is received in a complete stopping period of the train or not, wherein the complete stopping period is a data processing period of detecting complete stopping of the train; if yes, determining that the ground current moment in the ATO operation plan is the complete stopping moment of the train; if not, determining a complete stop moment according to a first data processing cycle of the received ATO operation plan and a complete stop cycle; and calculating the departure countdown of the target stop by using the complete stop time and the departure time. The method is used for the vehicle-mounted system of the train to automatically calculate the departure countdown.
