Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a method and device for controlling train operation between stations. Background Art

[0002] Punctual operation is a major advantage of urban rail transit compared to other modes of travel. In the current urban rail transit signal control system, during the debugging process, trains are repeatedly operated in different sections at different operating levels to obtain the running time data of trains between stations.

[0003] At present, the process of train operation between stations is that the ATO (Automatic Train Operation System) system queries the maximum operating speed corresponding to the interval operation level issued by the ATS (Automatic Train Supervision System), and calculates the current target speed of the train in real time based on the line speed limit, slope, traction and braking related parameters, and controls the train operation. Therefore, the on-time operation of the train depends on the speed data or time data obtained by repeated operation between stations at different operation levels. This operation mode has certain defects. The operation time corresponding to different operation levels of the train is fixed, and the interval operation time cannot be flexibly adjusted; because the train operation performance and operation environment change in real time when the train is running in the operation interval, if the fixed interval operation time is continued to be used to control the train, it is easy to cause the train to be late or early, which in turn leads to a low on-time rate of train operation between stations.

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Combine the following Figure 1-Figure 3 The train station operation control method of the present invention is described. The execution subject of the method is a train station operation control device, which can be a train automatic driving system ATO or other systems that can intelligently control the train, and this embodiment does not specifically limit this.

[0047] The following describes the train station operation control method in this embodiment by taking the execution subject as ATO as an example.

[0048] like Figure 1 As shown, it is one of the flow charts of the train station operation control method provided by the present application, and the method specifically comprises the following steps:

[0049] Step 101, according to the operation plan of the target train sent by the automatic train monitoring system ATS, obtaining the operation path of the target train from the current position to the target platform;

[0050] Among them, the target train is a train that needs to be controlled for inter-station operation, including but not limited to subways and high-speed railways.

[0051] The target platform is the destination platform of the train; the operation plan at least carries the identification information of the target platform and the planned operation time.

[0052] Optionally, the ATO monitors the ATS in real time, and when obtaining the operation plan of the target train sent by the automatic train monitoring system ATS, parses the identification information of the target platform from the operation plan, and determines the operation path of the target train from the current position to the target platform in the electronic map according to the identification information of the target platform.

[0053] Step 102, in the running path, obtaining the target section where the current position of the target train is located, and obtaining the theoretical running time and the planned running time for the target train to leave the target section from the current position according to the running plan;

[0054] Optionally, when the running path of the target train from the current position to the target platform is obtained, multiple speed limit sections in the running path can be queried in the electronic map, and the target section according to the current position of the target train can be determined among the multiple speed limit sections.

[0055] According to the operation plan, the operation route information of the operation path can also be queried in the electronic map, including but not limited to the static speed limit information and slope information of the route; and the operation speed information, acceleration information, deceleration information and cruise idling information of each speed limit interval can be calculated based on the operation route information.

[0056] When the target section where the current position of the target train is located is obtained, the running speed information, acceleration information, deceleration information and cruise coasting information of the target section can be obtained. According to the running speed information, acceleration information, deceleration information and cruise coasting information, the theoretical running time of the target train from the current position to the target section under the ideal running state is calculated; at the same time, the planned running time of the target train from the current position to the target section is parsed from the running plan.

[0057] Step 103, obtaining a running time adjustment amount of the target train in a target running state according to a time deviation between the theoretical running time and the planned running time and historical running information of the target train in the target section;

[0058] Among them, the historical operation information is the actual operation information of the target train that has run in the target section, that is, the operation information generated by the target train running from the starting position of the target section to the current position at a historical moment, including but not limited to the historical operation time information and historical operation speed information of the target train under each operation state, which is not specifically limited in this embodiment.

[0059] In order to simplify the interval operation model, the target interval can be divided into the start acceleration state, the cruise coasting state and the brake deceleration state. Accordingly, the target state can be any state among the start acceleration state, the cruise coasting state and the brake deceleration state. In this embodiment, the cruise coasting state is preferably used as the target state.

[0060] Optionally, when the planned running time and theoretical running time of the target train leaving the target section from the current position are obtained, the time deviation between the theoretical running time and the planned running time is calculated. When the time deviation value is not 0, the running time and running speed of the train in the target section are adjusted to ensure that the train can leave the target section according to the planned running time, and then determine that the train can run to the target platform according to the planned running time, so as to improve the low punctuality rate of train operation between stations.

[0061] Optionally, when there is a time deviation between the theoretical running time and the planned running time, the running time adjustment amount of the target train under the target running state is calculated based on the time deviation value and historical running information such as historical running time information and historical running speed information of the target train under various running states within the target interval.

[0062] Step 104, adjusting the target speed of the target train in the target running state according to the line information of the target section and the running time adjustment amount, and controlling the target train to leave the target section from the current position according to the adjusted target speed.

[0063] Optionally, after obtaining the running time adjustment amount, the target running speed of the train under the target state can be adjusted according to the line information and the running time adjustment amount; and the target train is controlled to leave the target section from the current position at the adjusted target speed, so that the actual running time of the target train leaving the target section from the current position according to the adjusted target speed is consistent with the planned running time, thereby improving the accuracy of the train arriving at the station on time.

[0064] It should be noted that, when the train needs to enter the next section of the target section, it can also continue to obtain the theoretical running time and planned running time of the target train leaving the next section from the current position according to the operation plan issued by ATS in real time, and when the theoretical running time and the planned running time are inconsistent, continue to control the target train according to the above steps 101-104, so that the actual running time of the target train in any section between the two platforms is consistent with the planned running time, so that the target train can arrive at the station accurately and improve the punctuality rate of train operation between stations.

[0065] In addition, when the target train arrives at the target platform, the line information of each speed limit section between the departure station and the target station can be cleared. When ATO receives the operation plan of the target train to the next platform sent by ATS, it continues to adjust the running time and running speed of each speed limit section of the train from the target platform to the next platform according to the above steps 101-104, thereby improving the punctuality rate of train operation between stations.

[0066] The train station operation control method provided in this embodiment receives the operation plan of the target train sent by the ATS in real time through the ATO system during the operation of the target train between platforms, obtains the theoretical operation time and the planned operation time of the target train leaving the target section from the current position according to the operation plan, and when the theoretical operation time and the planned operation time are inconsistent, obtains the operation time adjustment amount of the target train under the target operation state by combining the time deviation between the theoretical operation time and the planned operation time, as well as the historical operation information, and adaptively adjusts the target speed of the target train under the target operation state in real time based on the line information and the operation time adjustment amount, so that the actual operation time of the train in the target section is consistent with the planned operation time, thereby enabling the target train to arrive at the station accurately and improving the punctuality rate of the train operation between stations.

[0067] In some embodiments, adjusting the target speed of the target train in the target running state according to the line information of the target section and the running time adjustment amount includes:

[0068] When the target running state is a cruising coasting state, obtaining the cruising coasting time, average starting acceleration, average braking deceleration, and cruising coasting speed of the target train in the target section according to the line information;

[0069] According to the running time adjustment amount, the cruising coasting time, the average starting acceleration and the average braking deceleration, and the cruising coasting speed, obtaining the speed adjustment amount of the target train in the cruising coasting state in the target section;

[0070] The target speed is adjusted according to the speed adjustment amount.

[0071] Among them, the cruising coasting time, average starting acceleration and average braking deceleration, and cruising coasting speed are all the running information of the train when it is running under ideal conditions (i.e. normal conditions). The cruising coasting time and cruising coasting speed are respectively the running time and running speed required by the target train in the cruising coasting stage of the target section; the average starting acceleration is the average acceleration required by the target train in the starting stage of the target section; and the average braking deceleration is the average deceleration required by the target train in the braking stage of the target section.

[0072] Optionally, this embodiment can simplify the operation model of the target interval into a start-up acceleration phase, a cruising idling phase in the ceiling area, and a braking deceleration phase. When the known operation distance of the target interval is constant, combined with the vehicle traction braking establishment characteristics and the influence of the line slope, the ATO system can calculate the time deviation between the theoretical operation time of the target interval and the planned operation time issued by the ATS, and adjust the target speed of the cruising phase according to the time deviation, so as to adjust the average operation speed of the ceiling area in the cruising phase without changing the curve tracking control strategy during the operation process, so as to achieve the deviation correction between the planned operation time issued by the ATS and the theoretical operation time.

[0073] Optionally, when the target running state is the cruising coasting state, the step of adjusting the target speed of the target train in the target running state in step 104 specifically includes:

[0074] According to the line static speed limit information and slope information in the line information, the cruising and idling time T_adj, the average starting acceleration a_track and the average braking deceleration a_brake, as well as the cruising and idling speed V0 of the target train in the target section are calculated.

[0075] Then, the running time adjustment △t, the cruise coasting time T_adj, the average starting acceleration a_track and the average braking deceleration a_brake, as well as the cruise coasting speed V0 are substituted into the train dynamics equation. By solving the train dynamics equation, the speed adjustment △V of the target train in the cruise coasting state can be calculated.

[0076] Among them, since the running distance of the target section is constant, the quadratic train dynamics equation can be constructed according to the law of conservation of train power. The specific calculation formula is: △t×(V0-△V)=△V×(T_adj+(T_adj+△V / a_brake+△V / a_track)) / 2;

[0077] After the speed adjustment amount △V is obtained, the speed adjustment amount △V may be added to or subtracted from the cruising coasting speed V0 to adjust the target speed of the target train in the cruising coasting state to obtain the adjusted target speed.

[0078] Take the example of the planned running time being longer than the ideal running time. Since the planned running time is longer than the ideal running time, in order to avoid the train being early, it is necessary to increase the running time of the train in the target section, that is, it is necessary to reduce the target speed in the cruising and idling state. Therefore, the formula for adjusting the target speed of the target train in the cruising and idling state is:

[0079] V = V0 - ∆V;

[0080] Wherein, V is the adjusted target speed.

[0081] In this embodiment, during the interval operation stage, the running time of the train in the cruising and idling stage is increased or decreased, and the running speed is reduced or increased, so as to realize adaptive adjustment of the running time and running speed of the train in the cruising and idling stage, so that the target train can leave the target interval within the planned interval operation time issued by ATS, thereby improving the punctuality rate of the train.

[0082] In some embodiments, obtaining the cruising and idling time of the target train in the target section according to the line information includes:

[0083] According to the line information, the total running time, starting time and braking time of the target train in the target section are obtained;

[0084] The cruising and idling time of the target train in the target section is calculated according to the total running time, the starting time and the braking time.

[0085] Optionally, in step 104, the step of obtaining the cruising coasting time T_adj of the target train in the target section (i.e., the time available for adjustment in the target section) includes:

[0086] According to the line static speed limit information and slope information in the line information, the average starting acceleration a_track and the average braking deceleration a_brake of the target train in the target section, as well as the cruising and idling speed V0 and the length of the target section are calculated;

[0087] According to the average starting acceleration a_track and average braking deceleration a_brake of the target train in the target section, the cruising idling speed V0, and the length of the target section, the total running time T_base of the target train in the target section, the starting time T_track required for running in the starting phase and the braking time T_brake required for running in the braking phase can be calculated.

[0088] like Figure 2 As shown in the figure, the target interval mainly includes the start-up phase, the cruise coasting phase and the braking phase. Therefore, the total operation time T_base is the sum of the start-up time T_track, the braking time T_brake and the cruise coasting time T_adj. Therefore, when the total operation time T_base is known to be the start-up time T_track and the braking time T_brake, the calculation formula for the cruise coasting time T_adj is:

[0089] T_adj=T_base–T_brake–T_track;

[0090] By analyzing and calculating the line information, this embodiment can quickly and accurately obtain the time that can be used for adjustment in the target section, that is, the cruising idling time T_adj, so as to realize adaptive adjustment of the train running time and running speed according to the cruising idling time T_adj during the cruising idling stage, so that the target train can leave the target section within the planned running time of the section issued by ATS, thereby improving the punctuality rate of the train.

[0091] In some embodiments, obtaining the running time adjustment amount of the target train in the target running state according to the time deviation between the theoretical running time and the planned running time and the historical running information of the target train in the target section includes:

[0092] Determining the current running state of the target train at the current position according to the historical running information;

[0093] According to the current running state, obtaining a time adjustment strategy corresponding to the target train; the time adjustment strategy includes a strategy for adjusting the time according to the time deviation, or a strategy for adjusting the time according to the time deviation and the historical running information;

[0094] The running time adjustment amount is obtained according to the time adjustment strategy.

[0095] Optionally, the current running state of the target train at the current position can be determined as a start-up acceleration state, a cruise coasting state, or a brake deceleration state according to the running speed information in the historical running information. Different running states correspond to different time adjustment strategies; for example, the time adjustment strategy corresponding to the start-up acceleration state and the brake deceleration state is a strategy for adjusting the time according to the time deviation; the time adjustment strategy corresponding to the cruise coasting state is a strategy for adjusting the time according to the time deviation and the historical running information.

[0096] After determining the current running status of the target train at the current position, the time adjustment strategy can be determined according to the current running status as a strategy of adjusting the time according to the time deviation or a strategy of adjusting the time according to the time deviation and historical running information.

[0097] When it is determined that the time adjustment strategy is a strategy for adjusting time according to time deviation, the time adjustment is performed directly according to the time deviation to obtain the running time adjustment amount; when it is determined that the time adjustment strategy is a strategy for adjusting time according to time deviation and historical running information, the time adjustment is performed in combination with the time deviation and historical running information to obtain the running time adjustment amount.

[0098] In this embodiment, different time adjustment strategies are determined according to the different operating states of the target train at the current position, so as to accurately obtain the operating time adjustment amount of the target train under different operating states according to different time adjustment strategies, so as to accurately adjust the operating time of the train in the target section, so that the train can arrive at the platform accurately according to the planned operating time, thereby improving the punctuality rate of the train.

[0099] In some embodiments, obtaining the run time adjustment amount according to the time adjustment strategy includes:

[0100] When the current operating state is a start-up acceleration state, the time deviation is used as the operating time adjustment amount.

[0101] Optionally, when the current running state is the start-up acceleration state, it indicates that the target train has not reached the adjustable stage, that is, no time adjustment has been performed before the train starts running from the beginning of the target section to the current position. At this time, the time deviation can be directly used as the running time adjustment amount △t; wherein, the calculation formula of the running time adjustment amount △t is:

[0102] △t=T_plan–T_base;

[0103] Among them, T_plan and T_base are the planned running time and theoretical running time of the target train from the current position to the target section, respectively.

[0104] In this embodiment, when the current running state is the starting acceleration state, the running time adjustment amount can be quickly calculated based on the planned running time and theoretical running time of the target train leaving the target section from the current position, so as to realize fast and accurate adjustment of the running time of the train in the target section, thereby improving the punctuality rate of the train.

[0105] In some embodiments, obtaining the run time adjustment amount according to the time adjustment strategy includes:

[0106] When the current running state is the cruising and coasting state, the total historical running time and total historical running distance, as well as the historical starting time and historical starting distance of the target train in the target section are obtained according to the historical running information;

[0107] The operating time adjustment amount is acquired according to the total historical operating time, the total historical operating distance, the historical startup time and the historical startup distance, and the time deviation.

[0108] Optionally, when the current running state is the cruising coasting state, it indicates that the target train has reached the adjustable stage, that is, the time adjustment has been performed before the train starts running from the beginning of the target section to the current position.

[0109] In this case, it is necessary to first obtain the total historical running time and total historical running distance, as well as the historical start time and historical start distance of the target train in the target section based on the historical running information; then, based on the total historical running time and total historical running distance, as well as the historical start time and historical start distance of the target train in the target section, calculate the time deviation that has been adjusted before the current position, so as to calculate the remaining time required for adjustment based on the adjusted time deviation and the time deviation value calculated based on the ideal running time and the planned running time, and dynamically correct the running time adjustment amount to make the running time adjustment amount more accurate, so as to adjust the running time of the train in the target section more quickly and accurately, and further improve the punctuality rate of the train.

[0110] It should be noted that, in this embodiment, when the current operating state is the cruise idling state, the steps of obtaining the operating time adjustment amount based on the total historical operating time, the total historical operating distance, the historical start time and the historical start distance, and the time deviation can be executed in real time; multiple dynamic detection points can also be set in the cruising stage, and when the target train reaches the dynamic detection point, the steps of obtaining the operating time adjustment amount based on the total historical operating time, the total historical operating distance, the historical start time and the historical start distance, and the time deviation are executed. This embodiment does not make specific limitations on this.

[0111] In some embodiments, acquiring the running time adjustment amount according to the total historical running time, the total historical running distance, the historical startup time and the historical startup distance, and the time deviation includes:

[0112] According to the total historical running time and the historical start time, obtaining the actual cruising and idling time of the target train in the target section;

[0113] According to the total historical running distance and the historical starting distance, and the cruising and coasting speed corresponding to the target train obtained according to the line information, a theoretical cruising and coasting time of the target train in the target section is obtained;

[0114] The operating time adjustment amount is acquired according to the actual cruise coasting time, the theoretical cruise coasting time, and the time deviation.

[0115] Optionally, when the current running state is the cruise coasting state, the specific steps of obtaining the running time adjustment amount include:

[0116] According to the total historical running time and the historical start time, the actual cruising and coasting time of the target train in the target section is calculated, and according to the total historical running distance, the historical start distance and the cruising and coasting speed corresponding to the target train obtained according to the line information, the theoretical cruising and coasting time of the target train in the target section is calculated; then, according to the actual cruising and coasting time and the theoretical cruising and coasting time, the time deviation value adjusted before the target train reaches the current position is calculated, and the specific calculation formula is:

[0117] △t'=(T_realRun-T_track)–(D_realRun-D_track) / V0;

[0118] Among them, △t' is the time deviation value adjusted before the target train reaches the current position, T_realRun is the total historical running time (i.e. the actual running time of the train), T_track is the historical start time (i.e. the acceleration time of the known running curve), (T_realRun-T_track) is the actual cruising and idling time; D_realRun is the total historical running distance (i.e. the actual running distance of the train), D_track is the historical start distance (i.e. the acceleration distance of the known running curve), (D_realRun-D_track) is the theoretical cruising and idling time, and V0 is the cruising and idling speed corresponding to the target train obtained according to the line information.

[0119] After obtaining the adjusted time deviation value of the target train before reaching the current position, the remaining required adjustment time, that is, the running time adjustment amount △t, can be obtained according to the adjusted time deviation value, the total historical running time and the time deviation. The specific formula is:

[0120] △t=T_plan-T_base-△t';

[0121] Among them, T_plan is the planned running time issued by ATS received in real time, T_realRun is the total historical running time (that is, the actual running time of the train in the target section), T_base is the theoretical running time, and △t' is the time deviation of the completed adjustment.

[0122] In this embodiment, when the current operating state is the cruise idling state, the total historical operating time, historical start time, total historical operating distance and historical start distance, as well as the cruise idling speed and time deviation are combined to dynamically correct the operating time adjustment amount, improve the accuracy of the operating time adjustment amount, and the accuracy of the adjustment of the train's operating time and operating speed in the target section, thereby further improving the punctuality rate of the train.

[0123] like Figure 3 As shown, it is the second flow chart of the train station operation control method provided by this embodiment, which is mainly based on the existing control characteristics of the ATO system, that is, the target speed tracking control characteristics of the operation in the ceiling area of ​​the interval are traction-coasting-traction-coasting, combined with the vehicle traction braking establishment characteristics and the influence of the line slope, the deviation correction between the planned operation time issued by the ATS and the theoretical operation time can be achieved by adjusting the average operation speed of the ceiling area in the cruising stage without changing the curve tracking control strategy during the operation. Specifically, it includes the following steps:

[0124] Step 301, ATO determines the running path from the current position to the target platform (next station) according to the running plan of the target train sent by ATS, queries the line information such as the static speed limit information and slope information under the running path, and calculates the speed information of each speed limit area in the running path;

[0125] Step 302, for the above-queried route information, the acceleration / deceleration information and the cruise idling information of each speed limit area are calculated from the starting point to the end point in sequence;

[0126] Step 303, determining the running status of the target train at the current position;

[0127] Step 304, in the start-up acceleration phase, the running time adjustment is obtained according to the time deviation between the theoretical running time and the planned running time; and the speed adjustment △V of the target train in the cruising and idling state in the target section is obtained according to the running time adjustment, the cruising and idling time, the average starting acceleration and the average braking deceleration, and the cruising and idling speed; the target speed is adjusted according to the speed adjustment △V to obtain the adjusted target speed V;

[0128] Step 305, in the cruise coasting stage, firstly, the adjusted time deviation value △t' of the target train before reaching the current position is calculated based on the total historical running time and the historical start time, as well as the total historical running distance, the historical start distance and the cruise coasting speed corresponding to the target train obtained according to the line information; then, the remaining required adjustment time amount, i.e., the running time adjustment amount △t, is obtained based on the adjusted time deviation value, as well as the total historical running time and the time deviation; and the target speed is adjusted based on the running time adjustment amount, the cruise coasting time, the average start acceleration and the average braking deceleration, and the cruise coasting speed to obtain the adjusted target speed V.

[0129] In the prior art, fixed running time is used to control the operation of trains, and whether the train is on time is determined by the difference between the actual arrival time and the planned arrival time of the train by ATS, which results in the ATO being unable to make real-time adjustments according to the current early or late situation during the interval operation of the train to achieve the purpose of on-time arrival. If there is a difference between the actual running time of the operating train on the line and the planned running time, the train cannot automatically adjust the interval running time in real time. If the train is early or late, adjusting the train from non-punctual to on-time operation not only consumes a lot of time, but also has poor real-time performance, which leads to a decrease in the punctuality rate of operating trains.

[0130] In this example, the ATO system automatically adjusts the operating time according to the operation plan issued by the ATS in real time, by reducing or increasing the operating speed of the ceiling area during the cruising and idling (operating at a certain speed) phase, thereby improving the punctuality rate of the train.

[0131] The train station operation control device provided by the present invention is described below. The train station operation control device described below and the train station operation control method described above can be referenced to each other.
