By installing secondary radar and radio frequency antenna(RFID)on the train,the distance between the trains ahead is detected,and an alarm is triggered within 300m of the straight line section.In the case of ATP removal,the driver is assisted in driving through sound and light alarms.After the implementation of this measure,it can assist the driver in predicting the safety distance of the front vehicle,improve the safety of the train when operating at a protective speed of 25km/h without being limited to RM mode.It is expected that the train operating speed will be increased from 25km/h to 40km/h,maximizing the restoration of driving order and reducing the impact on passenger travel.
