Abstract

A control method for a train includes outputting an emergency brake instruction after detecting that a train control and management system is faulty, and outputting an emergency brake release instruction after detecting that the train control and management system is not faulty.

1 . A control method for a train, comprising:

         2 . The control method according to  claim 1 , further comprising:
 parsing, at a preset period, message data sent by the train control and management system;   incrementing a communication failure count by one if the parsing fails;
 determining that the train control and management system is faulty if the communication failure count exceeds a communication timeout threshold within a preset time; and 
 determining that the train control and management system is not faulty if the communication failure count does not exceed the communication timeout threshold within the preset time. 
   
     
     
         3 . The control method according to  claim 1 , further comprising:
 sending a request for entering a creep automatic train operating mode (CAM) to an automatic train supervision system after outputting the emergency brake instruction and detecting that the train stops and is located outside a creep stopping window; and   outputting, after receiving a CAM entering confirmation instruction sent by the automatic train supervision system, the emergency brake release instruction and controlling the train to enter the CAM.   
     
     
         4 . The control method according to  claim 3 , wherein after the sending a request for entering a CAM to an automatic train supervision system, the method further comprises:
 outputting the emergency brake release instruction if the CAM entering confirmation instruction sent by the automatic train supervision system is not received and it is detected that the train control and management system recovers.   
     
     
         5 . The control method according to  claim 1 , further comprising:
 sending prompt information requesting manual rescue to an automatic train supervision system after outputting the emergency brake instruction and detecting that a train stops and is located within a creep stopping window.   
     
     
         6 . The control method according to  claim 3 , further comprising:
 controlling, in the CAM, an automatic train protection system to perform safety protection on the train, and controlling, under three train control levels of creep traction, creep coasting, and creep braking, an automatic train operation system to control the train to operate; and   outputting an emergency brake-unreleasable instruction and sending prompt information requesting manual rescue to the automatic train supervision system when the train operates to a platform and stops within the creep stopping window.   
     
     
         7 . The control method according to  claim 6 , wherein after the outputting an emergency brake-unreleasable instruction, the method further comprises:
 controlling a train door and a platform screen door on a corresponding side to be opened if the train stops within a normal operation stopping window.   
     
     
         8 . A control apparatus for a train, comprising:
 a first control module, configured to output an emergency brake instruction after detecting that a train control and management system is faulty; and   a second control module, configured to output an emergency brake release instruction after detecting that the train control and management system is not faulty.   
     
     
         9 . The control apparatus according to  claim 8 , further comprising:
 a detection module, configured to parse, at a preset period, message data sent by the train control and management system, increment a communication failure count by one if the parsing fails, determine that the train control and management system is faulty if the communication failure count exceeds a communication timeout threshold within a preset time, and determine that the train control and management system is not faulty if the communication failure count does not exceed the communication timeout threshold within the preset time.   
     
     
         10 . The control apparatus according to  claim 8 , wherein the second control module is further configured to:
 send a request for entering a creep automatic train operating mode (CAM) to an automatic train supervision system after the emergency brake instruction is outputted and when it is detected that a train stops and is located outside a creep stopping window; and   output, after receiving a CAM entering confirmation instruction sent by the automatic train supervision system, the emergency brake release instruction and control the train to enter the CAM.   
     
     
         11 . The control apparatus according to  claim 10 , wherein the second control module is further configured to:
 output, after the request for entering the CAM is sent to the automatic train supervision system, the emergency brake release instruction if the CAM entering confirmation instruction sent by the automatic train supervision system is not received and it is detected that the train control and management system is not faulty.   
     
     
         12 . The control apparatus according to  claim 8 , wherein the second control module is further configured to:
 send prompt information requesting manual rescue to an automatic train supervision system after the emergency brake instruction is outputted and when it is detected that a train stops and is located within a creep stopping window.   
     
     
         13 . The control apparatus according to  claim 10 , wherein the second control module is further configured to:
 control, in the CAM, an automatic train protection system to perform safety protection on the train, and control, under three train control levels of creep traction, creep coasting, and creep braking, an automatic train operation system to control the train to operate; and   output an emergency brake-unreleasable instruction and send prompt information requesting manual rescue to the automatic train supervision system when the train operates to a platform and stops within the creep stopping window.
