Train automatic driving method based on atp/td loop system

Abstract

The invention provides an automatic train drive method based on an ATP / TD loop line mode. The automatic train drive method comprises the following steps: learning a zone Lm where a train is by an ATO according to the current position of the train, and learning a velocity-limiting signal of the train in the zone Lm according to the zone Lm where the train is; calculating a first recommended velocity V1 of the train in the zone Lm according to the velocity-limiting signal V of the train in the zone Lm; calculating a second recommended velocity V2 of the train in the zone Lm according to the velocity-limiting signal V of the next zone (Lm+1) of the zone Lm where the train is; taking the smaller velocity from the V1 and V2 as the recommended velocity Vm of the current zone Lm; and adjusting traction force or braking force of the train according to the difference of the current velocity and the recommended velocity Vm of the train by the ATO until the current velocity of the train is equal to the recommended velocity Vm. By utilizing the automatic train drive method, the running velocity of the train can be accurately controlled to realize automatic drive of the train.

Description

technical field [0001] The invention relates to the field of signal control, in particular to an automatic train driving method based on the ATP / TD loop system. Background technique [0002] The straddle-type monorail uses high-strength concrete beams (PC beams) as the track for vehicles, and adopts straddle-type monorail vehicles. The running wheels, guide wheels and stabilizing wheels of the vehicle all adopt pneumatic rubber tires. The ATP / TD system introduced from Japan, by pre-embedding the TD loop line in the track beam, uses the TD loop line to complete the detection of track section occupancy and the issuance of speed limit signals from the ground to the vehicle. [0003] The system architecture of the ATP / TD system is as follows: figure 1 shown. The vehicle-mounted ATP device actively sends codes through the TD ring line equipment to report the train track occupancy information to the ground. After the ground ATP device collects the train occupancy information of...

Problems solved by technology

[0007] However, the ATP / TD standard straddle monorail signal solution does not provide automatic driving functions. With the increase of subway passenger flow, the manual driving method under fixed blockage can no longer meet the needs of high-density line organization and operation, and the operation interval is relatively long. The labor intensity of the driver is high, and the manpower and management costs are high
