[0032] All terms used herein, including technical and scientific terms, have the same meanings as those generally understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having meanings consistent with the context of the specification, and should not be interpreted in an idealized or overly formal manner.
[0033] In the case of using expressions similar to "at least one of A, B, and C, etc.", it is generally to be interpreted as including one or more of the same as the meaning generally understood by one of ordinary skill in the art (for example, "a system having at least one of A, B, and C" should include but not be limited to a system having A alone, a system having B alone, a system having C alone, a system having both A and B, a system having both A and C, a system having both B and C, and / or a system having A, B, and C together, etc.).
[0034] It should be noted that the train operation control method, system and information execution method of the present disclosure can be used in the field of train operation control technology, and can also be used in any field other than the field of train operation control technology, such as the field of computer technology. The application field of the train operation control method, system and information execution method of the present disclosure is not limited.
[0035] In the technical solution of the present application, the user information (including but not limited to user personal information, user image information, user equipment information such as location information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved are all information and data authorized by the user or authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of related data comply with relevant laws, regulations and standards of relevant countries and regions, necessary security measures are taken, public order and good customs are not violated, and appropriate operation portals are provided for users to choose authorization or refusal.
[0036] In the research process, it is found that the TACS system in the related art, compared with the traditional CBTC system, although the ground function is restructured, the regional controller is cancelled, and the ground interlocking logic controller is simplified. However, considering that the vehicle undertakes the fundamental task of passenger transportation in the urban rail automation system, the evolution of the train operation control system from the CBTC system to the TACS system has not really decoupled, restructured the whole vehicle system architecture, function, hardware computing power, etc. level, has not carried out system design from the starting point of train intelligent autonomous operation, has not taken environmental uncertainty factors as the control input of train autonomous operation, and in special extreme cases, it will affect the train driving safety.
[0037] In the traditional rail transit operation, signal control is mainly based on ground centralized control and individual train control, and lacks intelligent perception of train autonomous control and train cluster collaborative control mode characterized by information sharing. In terms of environmental perception, the rain and snow mode of the existing system is mainly set by the dispatcher through external information to understand the weather condition and manually set the rain and snow mode, and the automation and intelligent level is low. The dispatcher lacks more input for the judgment of rail surface sliding.
[0038] In the train operation control process, the train lacks the perception of the environment, the control input is less, the safety protection has blind spots, and the means to deal with extreme weather is scarce. In terms of train state perception, in the train operation control, the train lacks real-time grasp of the train traction, braking characteristics, real-time load of the train, train traction and braking capacity values, and the control mechanism of the train idling and sliding. When the track surface is affected by external conditions such as rain, snow, ice, frost, fallen leaves, and poor maintenance state, the adhesion between the train wheel and the track surface decreases, the train braking distance is extended, and the train safety braking distance cannot be guaranteed. At this time, the dispatch personnel need to manually intervene to set the corresponding strategy, and the automation and intelligent level is low. The dispatch personnel lack more input for the judgment of the track surface sliding condition, and cannot timely and accurately intervene in the train operation. In summary, the train lacks autonomous perception ability, and cannot realize real-time dynamic adjustment and active safety protection of the train operation control according to the changes of the external environment. It is urgent to improve the autonomous perception, autonomous operation and active protection ability of the train operation.
[0039] In addition, with the application of intelligent algorithms such as image processing, deep learning and neural network, the computing power and performance of the traditional control center and the vehicle-mounted hardware platform cannot meet the requirements. It is urgent to upgrade the control center and the vehicle-mounted hardware platform to improve the data storage and computing ability of the control center and the vehicle-mounted hardware platform. At the same time, the number of control center and vehicle-mounted control devices should be reduced as much as possible.
[0040] Therefore, the embodiment of the present disclosure provides a train operation control method, which comprises the following steps: receiving first environment data sent by a trackside device, and train state data and second environment data sent by a vehicle-mounted device of each train in a running state in a train cluster; processing the first environment data, and the second environment data and the train state data of each train based on the respective lines of each train and the trackside device, to obtain the respective line operation states of a plurality of lines; determining an abnormal line from the plurality of lines based on the respective line operation states of the plurality of lines; determining operation control information of at least one target train in the train cluster which is running on or to be running on the abnormal line based on the line operation state of the abnormal line, and sending the operation control information to the at least one target train, so as to realize the cooperative control of the at least one target train.
[0041] Figure 1 The application scenario diagram of the train operation control method, system and information execution method according to the embodiment of the present disclosure is schematically shown.
[0042] As Figure 1As shown, the application scenario 100 according to this embodiment can include a control center 101, a network 102, trackside equipment 103 and onboard equipment 104. The network 102 is a medium for providing communication links between the control center 101, the trackside equipment 103 and the onboard equipment 104. The network 104 can include various connection types, such as wired, wireless communication links or optical fiber cables, etc.
[0043] The control center 101 can be composed of a computing power network cloud platform, can receive first environment data sent by the trackside equipment, and train state data and second environment data sent by onboard equipment of each train in a running state in the train cluster, so as to realize train intelligent scheduling, train-road collaborative perception information fusion processing, environment perception data processing based on artificial intelligence (AI), and train cluster collaborative control, safety protection based on "train-road-cloud" collaboration, etc. based on the above data.
[0044] The trackside equipment 103 is installed at the roadside area of each line, used to collect first environment data, and send the first environment data to the control center 101 and the onboard equipment 104.
[0045] The onboard equipment 104 is deployed on the train, which can perform environment perception and vehicle state perception, such as collecting second environment data, detecting the running state of the train to obtain train state data, and sending the second environment data and the train state data to the control center. The onboard equipment is also used to receive running control information sent by the control center, and perform train running control based on the running control information. Among them, the onboard equipment 104 located in different vehicles can perform real-time transmission of data, such as transmission of position, speed, idling detection result, and coasting detection result.
[0046] It should be noted that the train running control method provided by the embodiment of the present disclosure can generally be executed by the control center 101. The train running control method provided by the embodiment of the present disclosure can also be executed by a server or a server cluster different from the control center 101 and capable of communicating with the trackside equipment 103 and the onboard equipment 104. The information execution method provided by the embodiment of the present disclosure can generally be executed by the onboard equipment 104. The train running control method provided by the embodiment of the present disclosure can also be executed by a server or a server cluster different from the onboard equipment 104 and capable of communicating with the control center 101 and the onboard equipment 104.
[0047] It should be understood that Figure 1 The number of control centers, trackside equipment and onboard equipment in the above description is only illustrative. According to the needs of implementation, there can be any number of control centers, trackside equipment and onboard equipment.
[0048] The following will be based onFigure 1 The described scenario is achieved by Figures 2-7 The method of the disclosed embodiment is described in detail.
[0049] Figure 2 The flowchart of the train operation control method according to the embodiment of the present disclosure is schematically shown.
[0050] As Figure 2 shown, the method includes operations S210-S240, which can be performed by the control center.
[0051] In operation S210, the first environment data sent by the trackside device, and the train state data and the second environment data sent by the on-board device of each train in the running state in the train cluster are received.
[0052] In operation S220, the first environment data, and the second environment data and the train state data of each train are processed based on the respective lines on which each train and the trackside device are located, to obtain the respective line operation states of the multiple lines.
[0053] In operation S230, the abnormal line is determined from the multiple lines based on the respective line operation states of the multiple lines.
[0054] In operation S240, the operation control information of at least one target train in the train cluster that is running or to be running on the abnormal line is determined based on the line operation state of the abnormal line, and the operation control information is sent to the at least one target train, so as to realize the cooperative control of the at least one target train.
[0055] The trackside device includes a wayside perception module, a train-ground communication module, etc. The trackside device can be used to detect the environment data and vehicle operation data within the detection range of the device; the first environment data can include the environment data and vehicle operation data within the detection range of each trackside device. The environment data can be, for example, track surface condition data or weather state data, etc. The vehicle operation data can be, for example, vehicle speed, vehicle position, etc.
[0056] The train-ground communication module can be used to send the acquired sensor data to the control center and the on-board device. The trackside device can be, for example, a track state sensor, an environmental camera, a temperature and humidity sensor, a water accumulation sensor, a speed sensor, etc.
[0057] The multiple trackside devices can be deployed at the trackside through a preset deployment strategy to cover the road condition perception of key areas such as turnouts, curves, tunnel entrances, etc. The perception information is transmitted to the on-board operation control platform and the control center through the train-ground wireless network.
[0058] The vehicle-mounted device can be used to collect environmental data around the train or detect train operation state to obtain train state data. The vehicle-mounted device can include a perception device and a detection device, etc. The perception device can be, for example, a camera, a laser radar, a millimeter wave radar, a combined inertial navigation, a speed sensor, a running gear sensor, etc. The state detection device can be, for example, a coasting detection device, an idling detection device, etc.
[0059] In determining the respective line operation state of each line, the first environmental data, and the second environmental data and the train state data of each train can be processed. For example, the first environmental data, and the second environmental data and the train state data of each train can be divided into different line data pools based on the line information included in each of them, so as to avoid confusion between different lines.
[0060] The data pool of each line can determine whether the line state of each line is abnormal based on the data content included in each data pool, so as to determine the line operation state of each line.
[0061] The line operation state of each line can be used to reflect whether the line is abnormal, which can include the following aspects, such as the track surface state of the line and the operation state of the train running on the line, specifically, the track surface state is that there is snow in multiple sections, and the overall line is slippery. The operation state of the train can be that the train has a skid phenomenon, or the train has a fault, etc.
[0062] In some embodiments, the Simultaneous Localization and Mapping (SLAM) technology can be used to determine the line operation state of different lines based on the first environmental data, the second environmental data and the train state data obtained in real time.
[0063] In determining the abnormal line, the line operation state can be analyzed to determine whether each line is an abnormal line. And / or for each line, the track adhesion coefficient of each section in the line and the train state running on the line are used to determine whether the line is an abnormal line. Alternatively, the weather condition, the train operation state and the track surface state can be compared with the respective preset rules respectively, and the comparison results of the three aspects are combined to determine whether it belongs to an abnormal state.
[0064] For the abnormal line, the abnormal degree of the abnormal line can be determined based on the line operation state of the abnormal line, and the operation control information for at least one target train can be generated based on the generation strategy matched with the abnormal degree, so as to realize the cooperative control of the at least one target train.
[0065] According to the train operation control method of the present disclosure, by combining the train state data and the second environment data sent by the on-board equipment of each train in the train cluster in the running state with the first environment data sent by the trackside equipment, a more comprehensive understanding of the line surrounding environment and a more accurate grasp of the vehicle running state in each line are formed. And based on the lines of each device, these data are processed to obtain the running state of each line, and then the abnormal line is located. And based on the abnormal line state, the running control information of the target train running and to be running on the line is determined and issued, so that at least one target train makes a coordinated action based on the same abnormal environment state. Since this method not only performs more comprehensive and multi-dimensional autonomous perception of the line and the surrounding environment, but also generates running control information for dynamic coordinated adjustment of multiple target trains based on environmental changes. Therefore, at least part of the technical problems that the train has weak perception ability to the environment, and it is difficult to realize the coordinated control between trains based on environmental changes are solved, the more accurate perception of the train to the environment is realized, and the technical effect of the coordinated and efficient response of the trains around the environmental abnormal situation is realized.
[0066] According to an embodiment of the present disclosure, the trackside equipment is multiple; the first environment data is obtained by the multiple trackside equipment; based on the lines of each train and the trackside equipment, the first environment data, and the second environment data and the train state data of each train are processed to obtain the line running state of each of the multiple lines, which can include the following operations.
[0067] Based on the lines on which each train runs and the lines on which the multiple trackside equipment is located, the first environment data, and the second environment data and the train state data of each train are divided into first environment sub-data sets, second environment sub-data sets and state sub-data sets respectively matched with the multiple lines; for each line, based on the multiple sections included in the line, the first environment sub-data set, the second environment sub-data set and the state sub-data set matched with the line are subjected to data analysis to determine the section running state of each of the multiple sections; based on the section running state of each of the multiple sections of each line, the state marking of each section is performed on the preset line diagram to obtain the running state of each of the multiple lines; wherein the first environment sub-data set includes the first environment sub-data of each of the multiple sections of the line, the second environment sub-data set includes the second environment sub-data of each of the multiple sections of the line, and the state sub-data set includes the train state sub-data of each of the multiple sections of the line.
[0068] The multiple trackside equipment can be arranged in the corresponding sections of each line, therefore, by sorting the first environment data, the first environment sub-data of each of the multiple sections can be obtained.
[0069] In the operation state determination of multiple lines, the disordered data can be divided into respective matching lines through line division to obtain the first environment sub-data set, the second environment sub-data set and the state sub-data set respectively matched with each line.
[0070] For the first environment sub-data set, the second environment sub-data set and the state sub-data set of each line, the section operation state of each section can be determined by the first environment sub-data, the second environment sub-data and the train state sub-data corresponding to each section in each data set, for example, the first environment sub-data indicates that there is snow in section 1, the second environment sub-data indicates that there is snow and obstacle in section 1, and the train state sub-data indicates that the train is slipping in section 1, then section 1 can be marked as slippery, and the adhesion coefficient of section 1 can be calculated.
[0071] The adhesion coefficient of section 1 can be calculated and sent by the train passing through the section 1, or can be calculated by the control center. When multiple trains pass through the section 1, the train state sub-data, the first environment sub-data and the second environment sub-data of multiple trains can be integrated to obtain the state sub-data of the section. In some embodiments, on the basis of the above, the state sub-data can also be determined in combination with the adhesion coefficients of multiple trains.
[0072] Based on the operation state of each section of each line, the visualization marking can be completed on the preset line map to generate the overall operation state of the line.
[0073] For example, the color and icon can be rendered in the corresponding section area through the pre-drawn line map, for example, if section 1 is normal, the position of section 1 in the map is filled with a green block.
[0074] When the overall operation state of the line is determined, the preset line state evaluation standard can be combined to determine whether the overall line is abnormal, for example, if the normal section ratio is greater than 80%, the overall state of the line is normal.
[0075] According to the embodiments of the present disclosure, the perception layer can realize train autonomous positioning and external environment perception, which improves the train's perception ability of the external environment, and through the fusion of the first environment data collected by the trackside equipment and other train perception data, the automatic marking of the line state under adverse weather such as rain, snow, ice and frost can be realized, and the autonomous perception of the front and rear trains and track foreign objects can be realized. Based on the satellite navigation system, vision, inertial navigation, radar and other multi-source information fusion, the real-time generation and update of the operation state map of different lines and different sections are realized, and the precise positioning of the line operation state is realized.
[0076] According to an embodiment of the present disclosure, the first environment sub-data includes a first weather condition and a first section track surface condition; the second environment sub-data includes a second weather condition and a second section track surface condition; the train state sub-data represents a running condition of the train on the section; based on a plurality of sections included in the line, performing data analysis on the first environment sub-data set, the second environment sub-data set and the state sub-data set matched with the line to determine a section running state of each of the plurality of sections can include the following operations.
[0077] For each section, a target weather condition is determined based on the first weather condition and the second weather condition; a target section track surface condition is determined based on the first section track surface condition and the second section track surface condition; and a section running state of the section is determined based on the target weather condition, the target section track surface condition and the train state sub-data.
[0078] For each section, when determining the target weather condition, the first weather condition and the second weather condition can be cross-verified. For example, the trackside equipment of Section 1 detects continuous light rain and a wind speed of 2 m / s, and the train passing through the section feeds back that the rain is slightly larger within a range of 50 meters in front of the train head and the visibility is 600 meters, so the target weather condition is determined to be light rain, slightly larger local rain and a visibility of 600 meters, thereby retaining the overall monitoring result of the trackside equipment and supplementing the dynamic details captured by the train.
[0079] When determining the target section track surface condition, the first section track surface condition and the second section track surface condition can be fused and cross-verified with each other, so as to obtain a more complete and accurate target section track surface condition.
[0080] The section running state can be determined in combination with the target weather condition, the target section track surface condition, the train state sub-data and an evaluation model. Alternatively, the section running state can be obtained by fusing the target weather condition, the target section track surface condition and the train state sub-data, and performing semantic analysis on the description sentence obtained after the fusion.
[0081] For example, the evaluation model can be pre-trained, and the section running state can be obtained by inputting the target weather condition, the target section track surface condition and the train state sub-data into the evaluation model.
[0082] According to an embodiment of the present disclosure, by fusing multi-source information, the target weather and the target track surface condition of the section are more accurately determined, and then the above information is combined with the train running condition to comprehensively determine the section running state, so as to more accurately position the section running state.
[0083] According to an embodiment of the present disclosure, the line operation state of the abnormal line comprises track adhesion states of each section and an operation state of a target train running on the abnormal line; and determining the operation control information of at least one target train running on or to be running on the abnormal line in the train cluster based on the line operation state of the abnormal line can comprise the following operations.
[0084] Based on the preset weather prediction model, the track adhesion states of each section, and the operation state of the target train running on the abnormal line, the abnormal degree of the abnormal line is determined; in the case that the abnormal degree is a first abnormal degree, a train operation plan of the at least one target train is generated; and based on the train operation plan and the track adhesion states of each section, the operation control information is generated.
[0085] The preset weather prediction model can be used to predict the weather conditions of each section of each line at different time periods, so as to determine the line operation state of each abnormal line at different future time based on the predicted weather conditions, the track adhesion states of each section, and the operation state of the target train running on the abnormal line.
[0086] The implementation of the preset weather prediction model is not limited, and can be implemented based on a neural network model, such as a Long Short-Term Memory (LSTM), a pre-trained language model, etc.
[0087] The abnormal degree can be divided into different levels, such as a first abnormal degree, a second abnormal degree, and a third abnormal degree, etc. Further, different abnormal degrees can represent different line states, such as that the first abnormal degree can be that the abnormal line has a mild abnormality, and the second abnormal degree can be that the abnormal line has a severe abnormality. Specifically, the first abnormal degree can be that the sliding degree of the abnormal line is mild sliding.
[0088] When the abnormal degree is determined as the first abnormal degree, an adapted operation plan can be generated for the target train running and to be running. For example, the arrival time is optimized, the acceleration and deceleration time is fine-tuned to ensure that the train punctuality rate is not affected. For the target train to be running, the departure time is re-planned to avoid the current peak pressure of the abnormal line, for example, a train originally planned to depart after 10 minutes is delayed to depart after 15 minutes to relieve congestion; if multiple target trains to be running need to enter the abnormal line, the departure interval is staggered to reduce the train density in the section, etc.
[0089] The train operation plan and the track adhesion states of each section can be packaged as the operation control information and sent to each target train.
[0090] According to an embodiment of the present disclosure, by combining the preset weather prediction model and the line operation state of the abnormal line, the segment operation state of each target train when arriving at each segment of the abnormal line is further analyzed, so as to realize the abnormal prediction and real-time detection of the abnormal line, and the cooperative operation plan of each train is made. The operation control information is generated by the train operation plan and the track adhesion state, so that the cooperative operation of each train can be realized, and the real-time state of each segment can also be grasped.
[0091] According to an embodiment of the present disclosure, the real-time perception and interaction of the information such as speed, position, track adhesion state, etc. between vehicles in the train cluster can be realized by relying on the existing signal system communication network, the optimal scheduling, cooperative control and safety protection of the train cluster are realized, and the train efficiency and safety are improved.
[0092] According to an embodiment of the present disclosure, through the information sharing between the train individuals and groups, the overall management of the traction and braking forces between different constituent units of the train can be realized, the influence of different frames and axle idling and slipping on the train operation control is reduced, the communication delay between the core functions of the train operation control is shortened through the deep fusion and interaction of the train core operation control system, the train response time and control accuracy are improved, and the train braking distance is shortened.
[0093] According to an embodiment of the present disclosure, by fusing the perception information of the vehicle and the trackside facility, the information in the cloud is shared in real time to the train that is driving, the train operation environment cooperative perception is realized through the fusion of the autonomous perception information and the cloud sharing information, the beyond-visual-range perception of the train is realized, and the car-car and car-ground cooperative decision is realized.
[0094] According to an embodiment of the present disclosure, through the AI perception algorithm, the ability of the deep neural network in data expression can be excavated, the network design and parameter optimization are combined, the recognition of different traffic objects and road surface environments can be realized, and the control input information is provided for the individual and group control of the train.
[0095] According to an embodiment of the present disclosure, the train cluster cooperative control layer can start from the global, realize the train operation curve planning and tracking control, use the control center to calculate the energy consumption optimal driving strategy online, dynamically regulate and control the whole vehicle power system, and realize the large-range multi-train cooperative control energy-saving driving.
[0096] Figure 3 A flowchart of an information execution method according to an embodiment of the present disclosure is schematically shown.
[0097] As shown in Figure 3 , the method comprises operations S310-S330.
[0098] At operation S310, in response to the train receiving the operation control information, a departure time point and a running speed curve are determined based on a train operation plan included in the operation control information, wherein the operation control information is obtained by using the train operation control method described above.
[0099] At operation S320, braking parameters matched with track adhesion states of each section are determined based on the track adhesion states of each section included in the operation control information.
[0100] At operation S330, the train is controlled based on the departure time point, the running speed curve, and the braking parameters.
[0101] After the train receives the operation control information, the train operation plan included in the operation control information can be parsed, and relevant parameters such as basic information such as planned departure time, estimated passing time of each section, section speed limit threshold, and station stopping time length are extracted.
[0102] In combination with the current state of the train, the actual departure time point of the train during operation can be determined by whether the train is in standby state, whether the on-board equipment is normal, and passenger boarding and alighting progress. For the train to be operated, the departure time in the operation plan can be used as a reference, and the station dispatching situation, such as whether the previous train is delayed, can be used to fine-tune the departure time point to ensure that the departure time point matches the overall scheduling demand of the line.
[0103] In determining the running speed curve, the section speed limit in the operation plan can be used as a reference, and the train performance parameters, track adhesion states of each section, and line slope information can be used to generate a continuous speed change trajectory.
[0104] For example, in the departure phase, the initial acceleration can be set according to the adhesion state of the starting section; in the section running phase, the transition nodes of acceleration, constant speed, and deceleration are planned according to the speed limit values of different sections to ensure smooth transition of the speed curve.
[0105] The track adhesion state can be divided into different state levels, including dry track condition, wet track condition, and low adhesion condition. Different state levels can correspond to different braking parameters. When the train senses changes in environmental temperature, humidity, and wheel-rail adhesion state through autonomous sensing capability, the braking parameters can be adjusted autonomously, and the train safety braking distance can be automatically adjusted under the action of the safety braking model to realize safety protection in the individual and group automatic driving process of the train. The braking parameter can be a guaranteed emergency brake rate (GEBR).
[0106] The braking parameters corresponding to different state levels can be constructed in advance, such as: for common low adhesion working condition scenes such as rain, snow, ice, frost, gear box oil, etc., a list of guaranteed emergency braking rates under corresponding typical different adhesion coefficient working conditions is formed through tests, and when the train is running, through on-board sensing, vehicle-road cooperative sensing, central weather forecasting, and identification through the control center sensing fusion model, the guaranteed emergency braking rate (GEBR) is accurately matched.
[0107] According to the embodiments of the present disclosure, the departure time point and the running speed curve are determined based on the operation control information, so that the train control is performed through the departure time point and the running speed curve, and the section congestion or the waste of transport capacity caused by time deviation is reduced. In combination with the matching of the braking parameters under the adhesion state of each section track, the train can adopt an adaptive braking strategy under different adhesion conditions to avoid the risks of slipping, sliding and the like caused by insufficient braking or excessive braking, and the train safety is ensured. That is, through the cooperative control of the departure time, the speed curve and the braking parameters, the train can not only be efficiently operated according to the plan in the complex line environment, but also dynamically adjust the operation mode according to the track adhesion change, reduce the operation failure caused by the environment or the track surface problem, and reduce unnecessary energy consumption and wheel-rail wear.
[0108] According to the embodiments of the present disclosure, the train state sub-data includes: a train idling detection result; the train idling detection result includes an idling state value, an idling occurrence period, an idling occurrence position, and an idling acceleration; the idling acceleration is one of the parameters for reflecting the track adhesion state; and the train idling detection result is obtained by detecting the train as follows.
[0109] In a case where the speed of the train is in a first speed range, an acceleration or a speed difference of a wheel shaft driven by a traction motor in the train is detected to obtain a first detection result, and the speed difference is a speed difference between the wheel shaft and any wheel shaft in the train; in a case where a first acceleration of a target wheel shaft represented by the first detection result is greater than a preset acceleration threshold or a first speed difference is greater than a preset speed difference threshold, it is determined that the train idles, and an actual output traction force is changed from a first traction force to a second traction force, and the first traction force is greater than the second traction force; in a case where a second acceleration of the target wheel shaft is less than or equal to the preset acceleration threshold or a second speed difference is less than or equal to the preset speed difference threshold, the second traction force is updated at a preset gradient until the updated second traction force is consistent with a target traction force; and a difference between the first acceleration and the preset acceleration threshold is taken as an idling acceleration.
[0110] The detection side for the idling detection is not limited, and can be realized by a train traction force management module in the train or by a control center based on data sent by the train.
[0111] The first speed range can be a low speed range, and a specific value thereof can be determined according to actual conditions.
[0112] Figure 4 A flowchart of performing train idling detection according to an embodiment of the present disclosure is shown schematically;
[0113] As shown in Figure 4 , performing train idling detection can include operation S410~operation S408.
[0114] In operation S401, wheel shaft speed acquisition and calculation are performed on the traction system.
[0115] Speed acquisition can be performed on the wheel shaft driven by the traction motor in the traction system, and speed difference and acceleration are calculated.
[0116] In operation S402, it is determined whether there is a target wheel shaft with a first acceleration greater than a preset acceleration threshold or a target wheel shaft with a first speed difference greater than a preset speed difference threshold. If the determination is yes, operation S403 is performed; if the determination is no, operation S401 is returned.
[0117] In operation S403, it is determined that the train idles, and an idling state value is fed back.
[0118] In operation S404, the actual output traction force is reduced.
[0119] That is, the actual output traction force is changed from a first traction force to a second traction force, and the first traction force is greater than the second traction force.
[0120] In operation S405, it is determined whether the second acceleration of the target wheel shaft is less than or equal to the preset acceleration threshold or the second speed difference is less than or equal to the preset speed difference threshold. If the determination is yes, operation S406 is performed. If the determination is no, operation S404 is returned.
[0121] In operation S406, the second traction force is updated at a preset gradient until the updated second traction force is consistent with the target traction force.
[0122] The actual output traction force can be gradually increased to follow the target traction force until the actual traction force is consistent with the target traction force.
[0123] In operation S407, the idling acceleration is calculated.
[0124] The idling acceleration is calculated when the actual traction force is consistent with the target traction force.
[0125] In operation S408, the idling state value or the idling state value and the idling acceleration are fed back.
[0126] At the same time, information such as the idling occurrence period and the idling occurrence position can be fed back.
[0127] In the case where the above idle running detection is implemented by the train traction force management module, the above information is fed back to the train operation control platform and the control center; in the case where the above idle running detection is implemented by the control center, the above information is fed back to the train operation control platform.
[0128] The idle running state value can be a preset value representing whether idle running occurs, for example, 0 can be set for the idle running state, and 1 can be set for the non-idle running state.
[0129] According to an embodiment of the present disclosure, by idle running detection when the train speed is in the first speed range, the idle running occurrence position, idle running acceleration and other data are determined, and the train and the control center both hold the above data through communication transmission, which on the one hand realizes real-time detection and modification of the train abnormal situation, and on the other hand can reflect the line condition through the train state to realize train cooperative control.
[0130] According to an embodiment of the present disclosure, the train state sub-data includes: train coasting detection results; the train coasting detection results include a coasting state value, a coasting occurrence time period, a coasting occurrence position and a coasting deceleration value; the coasting deceleration value is one of parameters reflecting the track adhesion state; the train idle running detection results are obtained by detecting the train as follows: the train coasting detection results are obtained by the following method.
[0131] In the case where the speed of the train is in the second speed range, the rotational shaft speed deviation detection is performed on a plurality of wheels in the same brake unit of the train to obtain a second detection result, the rotational shaft speed deviation detection is to subtract the rotational shaft speeds of the plurality of wheels from a rotational shaft speed threshold value, and to compare the plurality of rotational speed differences with a preset rotational speed difference threshold value, the rotational shaft speed threshold value is determined from the rotational shaft speeds of the plurality of wheels; in the case where it is determined that the second detection result represents that there is a rotational speed difference greater than the preset rotational speed difference threshold value, it is determined that there is a target wheel in the brake unit that is in a coasting state, and the brake force output mode is switched from unit control to wheel control, so as to switch the first brake force output to the target wheel to a second brake force, the first brake force being greater than the second brake force; in the case where it is determined that the target wheel switched to the second brake force is still in the coasting state and the coasting duration is greater than a preset duration, the electric brake function for the target wheel is turned off, and the pressure in the air brake cylinder for the target wheel is released; in the case where it is determined that the rotational shaft speed of the target wheel is in an ascending state, the air brake cylinder for the target wheel is inflated; in the case where it is determined that the target wheel is in a normal state, the coasting deceleration value is determined based on the current rotational shaft speed of the target wheel, the rotational shaft speed at the coasting start time and the coasting duration.
[0132] The detection method for the coasting detection is not limited, and can be implemented by a train brake force management module in the train, or can be implemented by the control center based on the data sent by the train.
[0133] The second speed range can be a high speed range, and a specific value thereof can be determined according to actual conditions.
[0134] Figure 5 A flowchart of train coasting detection according to an embodiment of the present disclosure is schematically shown.
[0135] As shown in Figure 5 The train coasting detection can include the following operations S501-S507.
[0136] In operation S501, the rotational shaft speed in the braking system is collected and calculated.
[0137] The rotational shaft speeds of multiple wheels in the train under the same braking unit are collected and calculated. In the calculation process, the rotational shaft speeds of the multiple wheels are subtracted from a rotational speed threshold value, and the multiple rotational speed differences are compared with a preset rotational speed difference threshold value. The rotational speed threshold value is the highest rotational speed from the rotational speeds of the multiple wheels.
[0138] In operation S502, whether there is a target wheel with a rotational speed difference greater than the preset rotational speed difference threshold value. If yes, operation S503 is performed. If no, operation S501 is returned.
[0139] In operation S503, it is determined that the target wheel is coasting, and the coasting state values of the multiple wheels are fed back.
[0140] In operation S504, the braking force of the target rotational shaft for the target wheel is reduced.
[0141] When coasting occurs, in order to fully utilize the braking force, the coasting control can be converted to shaft control on the basis of the frame control, and the braking force output to the target rotational shaft is reduced. When the coasting exceeds the specified time, the air brake request cuts off the electric brake, and the corresponding shaft air brake starts to gradually release the brake cylinder pressure to restore the shaft speed. When the shaft speed shows a trend of recovery, the brake cylinder pressure starts to charge, but the recovered brake cylinder pressure is not more than the brake cylinder pressure required by the current level and load.
[0142] In operation S505, it is determined whether the rotational speed difference of the target wheel is less than or equal to the preset rotational speed difference threshold value. If yes, operation S505 is performed. If no, operation S504 is performed.
[0143] In operation S506, a coasting deceleration value is calculated.
[0144] In operation S507, the coasting state values of the multiple wheels or the coasting state values and the coasting deceleration values of the multiple wheels are fed back.
[0145] At the same time, information such as the coasting occurrence period and the idling coasting position can be fed back.
[0146] When the multiple different braking units or the multiple target wheels are in the sliding, the average of the multiple sliding deceleration values can be taken as the sliding deceleration value of the whole vehicle, and the feedback is performed.
[0147] When the sliding detection is realized by the train braking force management module, the information is fed back to the train operation control platform and the control center, and the online main valve can be used for sending when sending; when the idling detection is realized by the control center, the information is fed back to the train operation control platform.
[0148] The sliding state value can be a preset value representing whether the train is in the sliding state, for example, the train in the sliding state can be set to 0, and the train not in the sliding state can be set to 1.
[0149] The train operation control platform can use the sliding deceleration value to perform automatic train control, and the control center can use the sliding deceleration value to perform train cluster optimization control.
[0150] According to the embodiments of the present disclosure, the threshold deceleration in the sliding state of the vehicle can be calculated through the sliding detection and the deceleration calculation, and sent to the control center. The control center can issue the sliding state to the train cluster through comprehensive analysis of the sliding states of different regions and different trains. The train can automatically adjust the driving and deceleration according to the sliding instruction, and can automatically select the emergency braking rate. When the rain and snow disaster weather causes large-area sliding on the whole line, the train can automatically adjust the operation plan, and mainly adjusts the interval operation time and other parameters on the train diagram level. When the sliding is serious, the system is degraded, and the manual driving mode is recommended.
[0151] According to the embodiments of the present disclosure, through the sliding detection when the train speed is in the second speed range, the sliding occurrence position, the sliding acceleration and other data are determined, and the train and the control center both hold the above data through communication transmission. On the one hand, real-time detection and modification of the train abnormal situation are realized, and on the other hand, the train state can reflect the line condition to perform train cooperative control.
[0152] According to the embodiments of the present disclosure, the above train control method can further include the following operations.
[0153] When the sliding deceleration value or the idling acceleration of the first train in the train cluster is obtained, a second train on the same line and located behind the first train is determined; the sliding deceleration value and the sliding occurrence position, or the idling acceleration and the idling occurrence position are sent to the second train, so that when the second train drives to the sliding occurrence position or the idling occurrence position, the train control is performed based on the sliding deceleration value or the idling acceleration, respectively.
[0154] According to an embodiment of the present disclosure, when the current train slips, the subsequent train can be informed in real time through the train-ground communication, and the control center cloud platform can directly issue an instruction, and the current train forms a train control strategy according to the positions and speeds of the front and rear trains and the working conditions, and issues a braking system and a traction system to realize active protection of train operation.
[0155] Figure 6 A flowchart of a train operation control method according to another embodiment of the present disclosure is schematically shown.
[0156] As shown in Figure 6 The method of operation control information generation and execution can include operations S601-S606.
[0157] In operation S601, the weather state perception of each section, the operation state perception of each train, and the track surface state perception of each section are obtained.
[0158] The weather state perception can be obtained based on the first weather condition included in the first environment sub-data, the second weather condition included in the second environment sub-data, and a preset weather prediction model.
[0159] The track surface state perception of each section can be obtained through the first section track surface condition included in the first environment sub-data and the second section track surface condition included in the second environment sub-data.
[0160] The operation state perception of each train can be obtained based on the train state data of each train.
[0161] In operation S602, the line operation state of the line is determined based on the weather state perception, the operation state perception of each train, and the track surface state perception of each section. In the case of a severe slip of the line operation state, operation S603 is performed; in the case of a light slip of the line operation state, operation S604 is performed; and in the case of no slip of the line operation state, operation S601 is performed.
[0162] The line operation state of the line can include the slip degree of the line, such as no slip, light slip, or severe slip.
[0163] The determination method of the line operation state is not limited, for example, by judging whether the weather is easy-to-slip weather, the number of vehicles or the total number of slips of the same section that occur in the slip or slip, and whether the track surface is an easy-to-slip track surface to determine the line operation state of each line. For example, when the weather is easy-to-slip weather, the number of vehicles or the total number of slips of the same section that occur in the slip or slip is greater than a preset value, and the track surface is an easy-to-slip track surface, it can be determined that the line operation state is severe slip.
[0164] In operation S603, the train is switched from the automatic driving mode to the manual driving mode.
[0165] In operation S604, the section sliding state of each section in the line is marked, and the original train operation plan of at least one target train of the line is adjusted to obtain operation control information.
[0166] In operation S605, the operation control information is sent to the at least one target train.
[0167] In operation S606, the target train implements operation control based on the operation control information.
[0168] For example, automatically adjusting acceleration and deceleration, automatically updating braking parameters, etc.
[0169] In operation S607, the operation control strategy is adjusted in the case where the target train determines that it has entered a next section with a different section operation state. For example, adjusting acceleration and deceleration, braking parameters, etc.
[0170] According to the embodiment of the present disclosure, by sliding detection and deceleration calculation, the threshold deceleration in the vehicle sliding state can be calculated and sent to the control center. The control center will issue a sliding state to the train group through comprehensive analysis of the sliding state of different areas and different trains. The train will automatically adjust the driving and braking force according to the sliding instruction, and can guarantee the automatic selection of the emergency braking rate. When a large-area sliding occurs on the whole line in a rain and snow disaster, the train can automatically adjust the operation plan, and mainly adjust the interval operation time and other parameters on the operation diagram level. In the case of serious sliding, the system is degraded, and the system enters the manual driving mode.
[0171] According to the embodiment of the present disclosure, through information sharing between individual trains and groups, the overall management of traction and braking force between different constituent units of the train is realized, the influence of different frames and shafts on the train operation control is reduced, the communication delay between the core functions of the train operation control system is shortened through deep fusion and interaction of the train core operation control system, the train response time and control accuracy are improved, the train braking distance is shortened, and the train is truly realized. Self-awareness, autonomous operation, and autonomous protection.
[0172] According to the embodiment of the present disclosure, at the vehicle-road cooperation level, relying on the existing signal system communication network, the real-time perception and interaction of information such as speed, position, and track adhesion between vehicles in the train cluster are realized, the optimal scheduling, cooperative control, and safety protection of the train cluster are realized, and the train efficiency and safety are improved.
