Problems solved by technology
However, this patent still uses the safety braking curve and the safety suspension curve to determine the location of the auxiliary parking area in essence, which cannot guarantee the safe operation of the train.
At the same time, simply adopting the strategy of two-way separate layout and then integration is not conducive to the economy of parking area layout, and it is difficult to achieve cost savings on the premise of ensuring the safe operation of trains

Embodiment
[0041] This embodiment provides a method for arranging the auxiliary parking area of a single-line bidirectional operating normally conductive maglev line. The innovation is the use of the improved reverse arrangement method and the one-way priority method.
[0042] (1) Improved reverse layout method
[0043] Will image 3 The line between station O and station D is regarded as a one-way running line, that is, the normal operating direction is the OD direction. Among them, H i and R i (i takes 1, 2, 3,..., n) represent dangerous points and accessible points respectively, P i is the intersection of the target speed curve and the minimum speed protection curve. Meanwhile, let l denote the length of the parking area, and the location of the parking area i is [S i ,S i +l]. and let S O is the dangerous point position of station O (located in the acceleration zone), S D It is the position of the reachable point of station D. Then the process of improving the reverse arr...

The present invention relates to a method for arranging an auxiliary parking area of a single-track two-way operating normally conductive maglev line, comprising: step S1: using an improved reverse arrangement method to obtain a parking area in a main direction, and using the acceleration area of a terminal station in a secondary direction as a reference parking area in this direction; S2: Use the improved reverse layout method to obtain the temporary parking area in the secondary direction; Step S3: According to whether there is a parking area in the main direction between the temporary parking area in the secondary direction and its reference parking area, obtain the parking area in both directions or the formal parking area in the secondary direction; Step S4: The two-way parking area or the official parking area in the secondary direction is used as the reverse reference parking area, and steps S2‑S4 are repeated until the parking area in both directions or the official parking area in the secondary direction enters the acceleration area of the starting station in the main direction. To the parking area and the official parking area in the secondary direction, the auxiliary parking area of the single-line two-way running normal-conduction maglev line is arranged. Compared with the prior art, the scientificity and economy in line planning and design are improved.
Description
technical field [0001] The invention relates to the field of operation control of maglev trains, in particular to a method for arranging an auxiliary parking area of a single-track two-way running constant-conduction maglev line. Background technique [0002] The conventional maglev train has no wheels, and the high-speed operation of the train relies on various interactions between the magnetic force between the train and the track. Among them, the power required for the suspension and internal lighting of the conventional maglev train mainly comes from the on-board power supply and on-board power generation device. When the train is running at high speed, the on-board power generation device can supply power to the train equipment and supply power to the on-board power supply. When the train is stationary or running at low speed, the on-board power supply supplies power to the train. When the power is low, the power supply rail is required to charge the power supply. ...
