Train door opening determination method and on-board controller

Abstract

A train door opening determination method includes obtaining a stop threshold, obtaining a cumulative ranging error, and instructing, according to the stop threshold and the cumulative ranging error, a train to open or not to open train doors.

1 . A train door opening determination method, comprising:
 obtaining a stop threshold;   obtaining a cumulative ranging error; and   instructing, according to the stop threshold and the cumulative ranging error, a train to open or not to open train doors.   
     
     
         2 . The train door opening determination method according to  claim 1 , wherein the obtaining a cumulative ranging error comprises:
 obtaining a cumulative driving distance; and   obtaining the cumulative ranging error according to the cumulative driving distance.   
     
     
         3 . The train door opening determination method according to  claim 2 , wherein the cumulative driving distance is a driving distance between a stop position of the train and a last transponder passed by the train before the train stops. 
     
     
         4 . The train door opening determination method according to  claim 1 , wherein the stop threshold comprises a first stop threshold used for instructing the train to automatically open the train doors, and the instructing, according to the stop threshold and the cumulative ranging error, a train to open or not to open train doors comprises:
 when the train accurately stops within the first stop threshold and the cumulative ranging error is less than a preset value, instructing the train to automatically open the train doors;   when the train accurately stops within the first stop threshold and the cumulative ranging error is greater than or equal to the preset value, forbidding the train from automatically opening the train doors; and   when the train does not accurately stop within the first stop threshold, forbidding the train from automatically opening the train doors.   
     
     
         5 . The train door opening determination method according to  claim 4 , wherein the stop threshold further comprises a second stop threshold used for instructing the train to manually open the train doors, and the instructing, according to the stop threshold and the cumulative ranging error, a train to open or not to open train doors further comprises:
 when the train accurately stops within the second stop threshold and the cumulative ranging error is less than the preset value, outputting a door allow signal to allow the train to open the train doors;   when the train accurately stops within the second stop threshold and the cumulative ranging error is greater than or equal to the preset value, forbidding the train from opening the train doors; and   when the train does not accurately stop within the second stop threshold, forbidding the train from opening the train doors.   
     
     
         6 . An on-board controller, comprising:
 an obtaining module, configured to obtain a stop threshold and a cumulative ranging error; and   an instruction module, configured to instruct, according to the stop threshold and the cumulative ranging error, a train to open or not to open train doors.   
     
     
         7 . The on-board controller according to  claim 6 , wherein the stop threshold comprises a first stop threshold used for instructing the train to automatically open the train doors, and the instruction module is further configured to:
 when the train accurately stops within the first stop threshold and the cumulative ranging error is less than a preset value, instruct the train to automatically open the train doors;   when the train accurately stops within the first stop threshold and the cumulative ranging error is greater than or equal to the preset value, forbid the train from automatically opening the train doors; and   when the train does not accurately stop within the first stop threshold, forbid the train from automatically opening the train doors.   
     
     
         8 . The on-board controller according to  claim 7 , wherein the stop threshold further comprises a second stop threshold used for instructing the train to manually open the train doors, and the instruction module is further configured to:
 when the train accurately stops within the second stop threshold and the cumulative ranging error is less than the preset value, output a door allow signal to allow the train to open the train doors;   when the train accurately stops within the second stop threshold and the cumulative ranging error is greater than or equal to the preset value, forbid the train from opening the train doors; and   when the train does not accurately stop within the second stop threshold, forbid the train from opening the train doors.   
     
     
         9 . A controller, comprising a memory, a processor, a receiver, a transmitter, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements a train door opening determination method, the train door opening determination method, comprising:
 obtaining a stop threshold;   obtaining a cumulative ranging error; and   instructing, according to the stop threshold and the cumulative ranging error, a train to open or not to open train doors.   
     
     
         10 . A computer-readable storage medium, storing a computer program, wherein the computer program, when executed by a processor, implements the train door opening determination method according to  claim 1 .
