Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It is to be noted that, unless otherwise specified, technical terms or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.

The embodiment of the application provides a subway operation control method, which specifically comprises the following steps as shown in fig. 1:

101. and determining the regional position of the subway train according to the operation information.

The operation information is determined based on preset road signs in a road network where the subway trains are located, the region positions are used for representing sections of the subway trains in the road network, and the road network comprises at least one section.

In rail transit operations such as subway trains, different sections are often provided in a road network thereof for the purpose of facilitating subsequent maintenance and investigation of vehicle behavior. Taking a subway train as an example, the subway train includes a platform section corresponding to each platform and an off-station section between two platforms. Therefore, when the subway train runs, the road network system of the subway train can detect which section in the line each subway train runs in real time. Specifically, in practical applications, in order to determine the operation condition of each train of subway trains, the road network system is generally implemented by setting a landmark in the road network, where the landmark may be understood as a mark and can be recognized by a sensor arranged in the road network, the landmark may be a fixed object or may be in the form of an electronic beacon, and the specific form may be determined according to different road network setting modes, which is not limited herein.

Whether the subway train needs to limit the running speed during running or not mainly depends on what situation exists in the current road network and to which position the subway train runs. Based on this, the position of the current subway train, that is, the area position, may be determined based on the operation information of the subway train first in the present embodiment.

102. And acquiring the speed limit information of the corresponding area position according to the area position and the preset speed limit condition.

The preset speed limit condition is preset based on the operation requirement of the road network and is used for limiting the highest operation speed of the subway train in operation in different sections.

In this embodiment, since the restricted speed of different sections may be different when the subway train is running, after the position of the subway train, that is, the location of the area is determined, it is necessary to determine the actual speed-limiting situation, that is, the speed-limiting information, based on the location of the area. Specifically, in this step, the selection may be performed based on a preset speed limit condition, where the preset speed limit condition may be actually understood as a limit to the running speed of the subway train based on different sections after an abnormal condition is found in the subway train line.

For example, when the preset speed limit conditions respectively include speed limit information a corresponding to the region position 1, the speed limit information corresponding to the region position 2 has 2 sub-regions 21 and 22 respectively being B1 and B2, and the speed limit information corresponding to the region position 3 has 3

sub-regions

31, 32 and 33 respectively being C1, C2 and C3, and the train moving direction is from the region position 1 to the region position 3, the region position where the current subway train is located is determined to be the region position 2 based on the foregoing steps, and the B2 is determined to be the minimum by comparing the sizes of the speed limit values of B1, B2, C1, C2 and C3, then the speed limit information corresponding to the current subway train can be determined to be the speed limit information B2 according to the method of this step.

103. And controlling the running state of the subway train according to the speed limit information.

After the speed limit information of the subway train is determined, it is explained at which speed the operation should be performed is already known at this time. In this step, the operation state of the subway train may be controlled based on the speed limit information, and specifically, the control manner in this step includes, but is not limited to, the following manners: on one hand, when the locomotive system of the subway train is provided with the automatic driving function, a speed limit instruction can be issued to the locomotive system based on the speed limit information, so that the speed of the subway train is adjusted to be kept below the speed corresponding to the speed limit information based on the automatic driving function of the locomotive system; on the other hand, when the automatic driving function is not set in the locomotive system of the subway train or the locomotive system is converted into manual driving, after the speed limit information is determined, the speed limit information can be output to the staff of the subway train, such as a driver, as the prompt information, so that the speed adjustment can be performed by the speed limit information in the process of manual driving, and the control of the running state of the subway train is realized.

Specifically, when the operation state of the subway train is controlled based on the speed limit information in this step, the operation state can be controlled according to any one of the above modes, and the specific mode can be selected based on the actual operation needs of the subway train, which is not specifically limited herein, as long as the subway train is ensured to operate based on the speed limit information.

The embodiment provides a subway operation control method, which can determine the regional position of a subway train according to operation information, then acquire speed limit information corresponding to the regional position according to the regional position and preset speed limit conditions, and finally control the operation state of the subway train according to the speed limit information, thereby realizing the subway operation control function. Compared with the prior art, the operation information is determined based on the preset road signs in the road network in which the subway train is located, the area position is used for representing the section of the subway train in the road network currently, the road network comprises at least one section, and the preset speed limit condition is preset based on the operation requirement of the road network and is used for limiting the highest operation speed of the subway train in the operation of different sections, so that the speed limit information at the current position can be determined based on the area position of the current subway train in the subway operation control process, and the speed control is carried out based on the speed limit information, namely the speed control can be carried out based on different sections when the subway train runs in different sections, compared with the conventional mode of limiting the inherent lower hourly speed, the speed per hour of operation that can nimble adjustment subway train based on the speed limit information of different sections just so can make some sections that have abnormal conditions restrict lower speed, and other sections then can need not to restrict at lower speed to the operating efficiency of subway train in whole circuit can be improved. In addition, under the abnormal condition that the operation safety of the subway train is not influenced, the subway train can be adjusted based on the speed limiting information, and the subway train does not need to be limited at the inherent lower speed any more, so that the influence of the excessively low speed on the operation efficiency of the subway train when the abnormal condition exists is reduced, and the overall operation efficiency is improved.

To explain in more detail below, an embodiment of the present application provides another access control method, specifically as shown in fig. 2, the method includes:

201. and acquiring the running direction and position parameters of the subway train.

The running direction is used for representing the current running direction of the subway train, and the position parameters are used for representing the current geographical position of the subway train.

Based on the foregoing description of the embodiment, in the process of controlling the operation of the subway, the operation information of the subway train is a basis for ensuring the subsequent control, and the key points thereof are the running mode and the geographical position of the subway train, so as to determine the regional position of the subway train in the whole road network subsequently. Therefore, in this embodiment, the driving direction and the position parameter of the current subway train need to be acquired as the operation information first.

Specifically, the process of acquiring the driving direction and the position parameter in this step may be performed in the following two ways:

mode A: the method comprises the steps of obtaining position information of two closest position beacons of a subway train during operation through a sensor preset on the subway train, and determining the running direction and the position parameters of the subway train according to the position information corresponding to the two position beacons respectively.

In the implementation process of the method, it can be understood that the sensor preset in the subway train is a unidirectional sensor, and only the position information of the two position beacons closest to each other in the running direction of the subway train can be obtained, so that what the running direction of the subway train is and the current geographic position of the subway train can be determined.

Mode B: acquiring a subway identification of the subway train, determining the current running direction of the subway train from vehicle running data according to the subway identification, acquiring the position information of the position beacon, which is closest to the running direction, of the subway train when the subway train runs through a sensor preset in the subway train, and determining the position information as the position parameter.

In the implementation process of the mode B, it can be understood that the sensor preset in the subway train is a range-type sensor, so that only the position information of a nearest position beacon is obtained, and only the geographic position of the current subway train can be known, and when the driving direction is not known, the identification information of the subway train, that is, the subway identification, needs to be obtained, and then the driving direction of the current subway train is obtained from the vehicle operation data recorded with the operation condition of each subway train.

Further, based on the method a, since the position information of the two closest position information needs to be acquired in the execution process, the position beacon may be divided into a first position beacon and a second position beacon, where the first position beacon is the position beacon closest to the subway train, and the second position beacon is the position beacon next closest to the subway train; the position information is divided into first position information and second position information.

Based on this, in the foregoing manner a, the position information of two closest position beacons when the subway train operates is obtained through a sensor preset in the subway train, and the driving direction and the position parameter of the subway train are determined according to the position information corresponding to the two position beacons, and when the method is executed, the method specifically includes:

firstly, acquiring the position of a first position beacon through the sensor preset in the subway train, and recording the position as first position information;

meanwhile, acquiring the position of a second position beacon through the sensor preset in the subway train, and recording the position as second position information;

and finally, determining the running direction of the subway train according to the first position information and the second position information, and determining the geographic position of the first position information or the geographic position of the second position information as the position parameter.

Therefore, the running direction of the subway train can be determined to be the direction from the first position beacon to the second position beacon through the position relation between the first position information and the second position information and the subway train, so that the running direction of the current subway train can be obtained, and the current geographical position of the subway train can be shown based on the first position information or the second position information as the position parameters. Because the whole process can be realized directly based on the sensor preset in the subway train, the time consumption caused by other programs or system intervention is reduced, and the efficiency of the whole subway operation control process can be improved.

Further, with regard to the foregoing mode B, the vehicle operation data may include an arrival order of each station when each train of the subway train is in operation;

the foregoing mode B: acquiring a subway identifier of the subway train, determining the current running direction of the subway train from vehicle running data according to the subway identifier, acquiring the position information of the position beacon, which corresponds to the closest running direction when the subway train runs, of the subway train through a sensor preset in the subway train, determining the position information as the position parameter, and specifically:

Firstly, acquiring the subway identification and the vehicle running data from a locomotive system of the subway train respectively;

then, according to the vehicle operation data, obtaining an arrival sequence of the subway train at each station in the current line, and determining the running direction of the subway train according to the arrival sequence;

and finally, acquiring the position information of the nearest position beacon corresponding to the driving direction through a sensor preset in the subway train, and determining the position information as the position parameter.

In this step, the locomotive system may be understood as a vehicle-mounted control system for controlling the operation of the subway train, and has an interactive communication function, in which an electronic map of the operation of the subway train and related information, such as vehicle operation data, of the operation of the subway train are embedded. The vehicle operation data may be understood as road network information in which all subway trains including the current subway train operate, and related information between each station and each station. Therefore, when the method B is executed in this embodiment, since the sensor preset in the subway train is a range sensor, the position information of the nearest position beacon can be collected, and the position beacon can be just passed by the subway train, or the running direction of the subway train is not passed yet, it is necessary to determine which direction the subway train runs to, i.e. the running direction, based on the arrival order of the current subway train on the route, and determine the position information as the position parameter.

According to the method of the step, the driving direction of the subway train is determined based on the arrival sequence of the subway train at each station in the current line, so that position comparison among a plurality of position beacons is not needed, the method of the embodiment can only acquire the position information of the nearest position beacon by using a common sensor during execution, the process of calculating the driving direction is omitted, and the calculation pressure of a system executing the method is reduced.

202. And determining the regional position of the subway train according to the operation information.

In this embodiment, based on the foregoing steps, the landmark may be a position beacon, where the position beacon is a marker disposed in the middle of a track or on a side of a track of the road network according to a preset distance. In practical applications, for convenience of maintenance and marking, position beacons are disposed at intervals in the track, and are generally disposed between two tracks. The running information is determined based on the position beacon, the existing facilities of the current subway train can be ensured to be utilized, additional facilities do not need to be arranged, and the cost for executing the method of the embodiment is reduced.

Based on the foregoing steps, since the operation information is actually determined by the driving direction and the position parameters, the present step can be based on: and determining the regional position of the subway train according to the driving direction and the position parameters. The operational information includes driving direction and position parameters.

Specifically, in practical applications, the determining the regional position of the subway train according to the driving direction and the position parameter in this step may be performed as follows:

firstly, obtaining road network information of the road network where the subway train is located from a preset electronic map, wherein the preset electronic map comprises the road network information corresponding to each road network;

and then, acquiring the region position corresponding to the position parameter according to the road network information and the driving direction.

In this step, the preset electronic map may be obtained from the locomotive system through communication interaction, and the preset electronic map may be understood as map data including the entire road network condition, and certainly, the method of this embodiment does not need all the map data, but only needs a small part of the map data, that is, data related to the current subway train, when executed, therefore, in this embodiment, road network information of the road network in which the subway train is traveling may be obtained from the preset electronic map, and since the road network information includes different geographic locations corresponding to each section, an actual location of the area, that is, an area where the current subway train is located on the road, may be determined based on the location parameters and the traveling direction determined in the foregoing step.

203. And acquiring the speed limit information of the corresponding area position according to the area position and the preset speed limit condition.

Further, this step may be specifically performed in the following manner when executed:

firstly, acquiring abnormal event information from the locomotive system, wherein the abnormal event information is used for representing the abnormal condition of the subway train in the current line;

then, determining a speed limit requirement corresponding to the abnormal event information in the preset speed limit condition, wherein the preset speed limit condition comprises at least one type of abnormal event information and the speed limit requirement corresponding to the abnormal event information, and the speed limit requirement comprises speed limit information corresponding to each area position;

and finally, acquiring the speed limit information corresponding to the area position in the speed limit requirement according to the area position.

Due to the fact that various different types of abnormal conditions may exist in the actual operation process of the subway train, for example, different conditions such as poor communication and large turning amplitude of the subway train in a certain area exist. Therefore, in the process of acquiring the speed limit information based on the area position and the preset speed limit condition, analysis can be performed based on different abnormal conditions. Specifically, in practical applications, different abnormal events and corresponding speed limit requirements may be set in advance, for example, in order to ensure that each station can stop for a longer time, under the condition that the running time required by the whole route is not changed, the consumption of off-station time needs to be reduced in order to ensure the overall running efficiency, the off-station process needs a higher speed of subway train running to offset the time occupied by the station when the station stops, and at this time, the speed limit of the area outside the station may be set in advance to be higher in the speed limit requirements corresponding to the "peak in the morning and evening" of the abnormal event (assuming that the past speed limit is 60km/h, and the peak in the morning and evening may be 80 km/h). At this time, when the subway train is running and the detected abnormal event information is the 'morning and evening peak', the speed limit requirement corresponding to the morning and evening peak can be obtained. And then when the area position of the current subway train is determined to be the out-of-station area, the speed limit information of the current subway train can be determined to be 80km/h based on the out-of-station area.

Of course, in practical application, because the types of the abnormal events are different, for example, some abnormal events require the deceleration of the subway train, different speed limit requirements can be set based on different abnormal event information, so that the speed of the subway train can be controlled according to actual requirements subsequently.

204. And controlling the running state of the subway train according to the speed limit information.
