Automatic train speed restricting and speed restriction removing method based on TCMS (train control and management system)

The invention relates to an automatic train speed restricting and speed restriction removing method based on a TCMS (train control and management system) and belongs to the field of decision management methods of railway vehicle speed restricting or speed restriction removing. The method is characterized in that a train speed restriction removing human-machine conversation control module using logic contacts as the entity foundation is added on the basis of an original TCMS, and a bullet train driver can directly perform fast retrieval on a sensor transmitting an alarm signal on an HMI (human-machine interface) and directly perform disable logic shielding on the logic contact corresponding to the sensor through a conversation interface. The method has the advantages that the method provides an effective approach to the driver for automatically removing a training speed over-restriction alarm state under the premise that the alarm of the sensor is determined as an false alarm, the over-restriction processing time under the condition is greatly reduced by 85%, and vehicle adaptability is increased evidently; meanwhile, the method is visual in logic, simple to operate and suitable for being popularized in the field.
