2. If the actual line running direction of the S direction port is changed into the departure direction (opposite to the preset direction), the logic check function of the occupation of the trigger interval is automatically closed, and a red indicating lamp is displayed on the interface; the driving command is continuously outputted to the section protection relays of the sections 1001G, 1002G, and 1003G, and the red light is displayed by the off button on the manual unlocking dial.
2.1, in this case, if the track relays of the sections 1001G and 1003G fall down, the logic state is recorded as normal occupancy, and the section protection relays of the sections 1001G and 1003G are kept driven;
2.2, after that, if the track relay of the section 1003G is sucked up, the logic state record is idle, and the section protection relay of the section 1003G keeps driving. 3. If the S direction port is changed into the vehicle receiving direction, the logic checking function of the occupation of the triggering interval is automatically started, the interface display shows that the lamp is turned off, and the turn-off button on the manual unlocking disc shows that the lamp is turned off; 1001G logic state is judged as fault occupation, and a corresponding section protection relay maintains driving;
3.1, in this case, if the track relay of the section 1002G falls down, the track relays of the sections 1001G and 1002G are sequentially cleared; 1001G is judged to be idle, and the corresponding interval protection relay maintains driving; and 1002G, judging that the occupation is lost by the logic state, and stopping driving the corresponding section protection relay.
In summary, the method for automatically checking the occupation logic of the switching interval according to the interval running direction solves the problems that the forward direction automatic blocking and the reverse direction automatic inter-station blocking lines running in two directions need to be manually operated by field personnel to check the opening or closing of the logic checking function after the field relocation operation by optimizing the processing logic of the interval comprehensive monitoring equipment, reduces the operation requirements of the field personnel and improves the usability of the equipment.
