C. each independent vacuum pipeline section is provided with a vacuum degree control system and an escape channel; the vacuum degree control system sets the matched vacuum degree according to the designed running speed of the train in the corresponding closed space, the higher the train speed is, the higher the vacuum degree is, the thinner the atmosphere is, the lower the train speed is, the lower the vacuum degree is, and the denser the atmosphere is;
D. the train can be started and accelerated in a normal atmospheric pressure state;
E. the vacuum degree control system extracts corresponding vacuum degrees from each pipeline space section according to the designed speed of the train to pass through each section to form segmented vacuum pipelines with different vacuum degrees;
F. when the train runs in the ith closed space section of the pipeline system, the partition doors at two ends of the closed space are in a closed state;

As shown in fig. 1 and fig. 2, the sectional type vacuum pipeline transportation method of the present invention operates as follows under both normal operation state and fault state:
first, normal operation state
1. According to the preset train running speed between the station A and the station B, the vacuum pipeline is divided into a plurality of sections of independent vacuum pipeline spaces by the partition doors.
2. In order to save investment, the station A, B and the adjacent low-speed section are set as non-vacuum sections, which can be open-air ground or underground, and are in normal atmospheric pressure state without considering vacuum pumping.
3. The vacuum pipeline section (high-speed section) sets a plurality of sections as vacuum degrees corresponding to the running speed according to the set running speed of the train.
4.

Second, failure state
When the train stops at a certain section of vacuum pipeline due to an unexpected fault, the automatic train operation control system starts a fault rescue state, controls the vacuum section to be automatically opened corresponding to the escape passage door and communicated with the escape passage, reduces the vacuum degree of the vacuum section as the escape passage is kept consistent with the external atmospheric pressure, and quickly restores to a normal atmospheric pressure state, so that passengers get off and escape.
It is worth pointing out that the acceleration is reduced as the train stops in and out of the station. The sectional type vacuum pipeline transportation system fully utilizes the acceleration reducing condition of the train, and is provided with a sectional vacuum section which is matched with the speed and gradually changes the vacuum degree, so that the gradual transition of the train from a vacuum state to a standard atmospheric pressure state (from the standard atmospheric pressure state to the vacuum state) is realized; when the train stops, the outside of the train is at standard atmospheric pressure, and personnel can finish getting on or off the train immediately.

The utility model discloses sectional type vacuum pipeline transportation system has practiced thrift the passenger greatly in the car time, has improved conveying efficiency, has reduced engineering complexity and engineering cost, more is fit for the engineering and uses.
It is worth pointing out that: at present, the highest running speed of the high-speed wheel-rail railway train in China is 350km/h under the standard atmospheric pressure, the speed is further increased, and the train bears larger air resistance and is more uneconomical. Limited by the starting and stopping of the train, the small radius of a plane curve of the line trend and the like, a section with the train running speed lower than 350km/h can exist in the vacuum pipeline transportation system. In order to save investment, the vacuum pipeline can be discontinuously laid along the transportation line direction. The utility model discloses can be in the following district of speed 350km/h, need not to adopt vacuum environment, cancel pipeline structure's setting, directly adopt the open-air line (be open-air line), even can not avoid passing through massif or other ground barriers, when must adopting tunnel structure, as long as speed is less than 350km/h, just can adopt traditional tunnel structure, avoid adopting expensive vacuum pipeline, can avoid adopting complicated vacuum pipeline technique in low-speed district sections such as near station switch district very much.
Example (b): taking the vacuum pipeline transportation mode adopted by Beijing to Shanghai as an example, the total length of the line is 1320km, and 4 middle stations are arranged along the line, namely, Jinan, Xuzhou, Nanjing and Suzhou. In order to save investment, 6 stations of Beijing, Jinan, Xuzhou, Nanjing, Suzhou and Shanghai can be set as open-air ground stations, and the stations and the adjacent low-speed sections are not paved with vacuum pipelines, but are only paved in the high-speed running section of the train between the two stations. The vacuum pipeline between adjacent stations is divided into a plurality of independent pipeline spaces by a certain number of partition doors according to the station spacing and the designed traveling speed curve, and the vacuum degree matched with the speed is extracted by a vacuum control system according to different designed running speeds in each section of pipeline space. After the vacuum pipeline transportation system is adopted, the highest speed of the train can reach 600km/h and above due to the reduction of air resistance, and the transportation time is greatly shortened.

(1) The higher the running speed is, the higher the vacuum degree controlled in the corresponding interval is, the thinner the dense atmosphere is, the air resistance of the train running does not rapidly increase according to the quadratic rule of the train speed, but rapidly decreases, the train is not limited by the air resistance any more, the train can utilize the most economical energy consumption to exert the higher speed, and the higher transportation efficiency is provided. (2) The lower the running speed is, the lower the vacuum degree controlled in the corresponding interval is, the denser the atmosphere is, the closer the environment in the pipeline is to the external atmospheric environment, when the train enters the station and stops, the pressure in the pipeline is reduced to be consistent with the external standard atmospheric pressure, so that personnel can freely transfer the train from top to bottom without limitation, the efficiency is greatly improved, and the problem of station transfer is solved; when the train emergently stops due to a fault, the automatic train operation control system starts a fault rescue state, controls the vacuum section to be automatically opened corresponding to the escape passage door and communicated with the escape passage, and reduces the vacuum degree of the vacuum section to be rapidly recovered to a normal atmospheric pressure state as the escape passage is kept consistent with the external atmospheric pressure, so that personnel can quickly escape and the problem of personnel rescue is solved.
