[0029] Hereinafter, embodiments of the disclosure will be described with reference to the accompanying drawings. However, it is to be understood that these descriptions are merely exemplary and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the disclosure. However, it will be apparent to one skilled in the art that one or more embodiments can be practiced without these specific details. In other instances, well-known structures and techniques have been omitted in order to avoid obscuring the concepts of the disclosure.
[0030] The terms used herein are merely used to describe specific embodiments and are not intended to limit the disclosure. The terms "include", "comprise" and the like used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.
[0031] All terms used herein, including technical and scientific terms, have meanings commonly understood by one of ordinary skill 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.
[0032] In the case of using expressions similar to "at least one of A, B, and C, etc.", in general, it should be interpreted to include one or more of the corresponding items, unless otherwise defined (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 A and B together, a system having A and C together, a system having B and C together, and / or a system having A, B, and C together, etc.).
[0033] In embodiments of the disclosure, the collection, updating, analysis, processing, use, transmission, provision, disclosure, storage, etc. of data involved (for example, including but not limited to user personal information) comply with relevant legal regulations, are used for legal purposes, and do not violate public order and good customs. In particular, necessary measures are taken to prevent illegal access to user personal information data, and to maintain user personal information security, network security, and national security.
[0034] In the embodiments of the present disclosure, the authorization or consent of the user is obtained before the personal information of the user is acquired or collected.
[0035] When the rail vehicle is running, there are many limitations due to the limited information obtained by the vehicle itself. At present, the vehicle cannot comprehensively and real-timely understand the specific conditions of the front section during running. For example, due to the range limitation of the sight distance, the vehicle cannot obtain the foreign matter information and track condition information of the front track, so that the vehicle cannot accurately and effectively handle the abnormal situation of the running environment. For example, due to the inability to obtain the running state information of other vehicles in the same period in time, the vehicle operation and management exist the situation that the power supply system exceeds the load that can be carried, thereby causing the voltage of the power supply system to fluctuate greatly, which seriously affects the running of the vehicle. When the vehicle needs to respond to the sudden change of the running environment in a short time, it usually needs to take emergency measures, which is easy to cause the passengers to panic and reduce the passenger's riding experience.
[0036] When the rail vehicle faces the above-mentioned sudden situation, due to the limitation of the above-mentioned information, the vehicle appears emergency deceleration or braking when facing the sudden situation, which reduces the safety and stability of the rail vehicle running. At the same time, the above-mentioned running adjustment strategy does not consider the demand of the passengers, which seriously affects the riding experience of the passengers and increases the uncertainty and risk of the trip.
[0037] Therefore, the embodiments of the present disclosure provide that after receiving the running state information of the vehicle, the passenger state information and the running environment information within the sight distance range, the running environment information outside the sight distance range is obtained, based on the above-mentioned information, the type of the running environment fluctuation of the vehicle during running is determined, according to different types of the running environment fluctuation, the state and demand of the passengers are considered, and then the running strategy of the vehicle is determined, so that the target vehicle can timely and accurately adjust the running strategy after the environment fluctuation, and can ensure the stable running of the vehicle under the condition of meeting the demand of the passengers, which improves the safety of the vehicle running, reduces the perception of the passengers to the running environment fluctuation, and improves the riding experience of the passengers.
[0038] The vehicle-ground integrated electromechanical system can realize real-time monitoring and information sharing of the running state of the vehicle through integration of the rail vehicle, the ground infrastructure and the cloud service, and can be applied to intelligent running control and management of the rail vehicle.
[0039] Figure 1 The system architecture diagram of the vehicle-ground integrated electromechanical system applicable to the vehicle running strategy generation method according to the embodiments of the present disclosure is schematically shown. It should be noted that, Figure 1The shown is only an example of a system architecture to which the embodiments of the present disclosure can be applied, to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.
[0040] As shown, the vehicle-ground integrated electromechanical system architecture 100 according to the embodiment includes a vehicle system 101, a vehicle-ground cooperative power supply system 102, a vehicle-mounted track detection system 103, a vehicle-ground cooperative maintenance system 104, and a vehicle-ground cooperative passenger service system 105, wherein the vehicle includes a vehicle network control system TCMS subsystem 101-1, a vehicle-mounted PHM 101-2, a vehicle-mounted track detection subsystem 101-3, and a vehicle-mounted PIS subsystem 101-4. Figure 1
[0041] The vehicle network control TCMS subsystem 101-1 can obtain information such as the positioning of the vehicle and the running state of the vehicle in real time. The vehicle-ground cooperative power supply system 102 can adjust the power supply of the vehicle in real time according to the network communication with the vehicle network control TCMS subsystem 101-1, provide the vehicle with traction force adapted to its running state, and realize the adjustment of the running state of the traction components of the vehicle system 101 to meet the running of the vehicle system 101 at the target running speed.
[0042] The vehicle-mounted track detection system 103 includes detection of track state information such as track geometric parameters and track wear conditions, detection of tunnel state information such as tunnel surface and tunnel air changes, and detection of contact network state information such as contact network geometric parameters and contact network voltage fluctuations. The above detection can be realized by collecting relevant images through sensors and performing image recognition or by intelligent devices to obtain detection results in real time. The vehicle-mounted track detection system 103 can communicate with the vehicle-mounted track detection subsystem 101-3 through network communication, so that the vehicle system 101 can obtain the running environment information of the vehicle in real time, and further determine the running environment fluctuation. The vehicle-mounted track detection system 103 can also send foreign matter intrusion track information to the vehicle-mounted track detection subsystem 101-3, and detect and send danger prompt information that is out of the visual range of the vehicle system 101 in real time.
[0043] The vehicle-ground cooperative maintenance system 104 can communicate with the vehicle-mounted PHM 101-2 through network communication to obtain important fault data of the train. The vehicle system 101 can also obtain maintenance record information of each component of the vehicle through network communication between the vehicle-ground cooperative maintenance system 104.
[0044] The vehicle-ground cooperative passenger service system 105 can obtain real-time video monitoring images, congestion detection information, passenger quantity information and the like in the vehicle compartment by communicating with the vehicle-mounted PIS subsystem 101-4, and send early warning broadcast information and the like to the vehicle-mounted PIS subsystem 101-4. Meanwhile, the vehicle-mounted PIS subsystem can obtain passenger identity information, passenger physical condition and the like by communication.
[0045] The above vehicle-ground integrated electromechanical system realizes real-time communication and data interaction between the vehicle and the ground, and provides a good information basis for determining the vehicle operation strategy under different conditions.
[0046] It should be understood that Figure 1 The number of system modules in the system 100 is only illustrative. Depending on the implementation needs, there can be any number and function of system modules.
[0047] Figure 2 An illustrative flowchart of a vehicle operation strategy generation method based on a vehicle-ground integrated electromechanical system according to an embodiment of the present disclosure is shown.
[0048] As shown in Figure 2 The method 200 includes operations S210-S230.
[0049] At operation S210, in response to receiving the operation state information of the target vehicle on the target path, the passenger state information in each vehicle compartment in the target vehicle, and the first running environment information within the line-of-sight range, the second running environment information within the line-of-sight range when the target vehicle is at the target position is obtained.
[0050] At operation S220, the running environment fluctuation type is determined according to the second running environment information and the first running environment information.
[0051] At operation S230, based on the running environment fluctuation type and the passenger state information in each vehicle compartment, the vehicle operation strategy is generated by adjusting the operation state information of each component.
[0052] According to an embodiment of the present disclosure, the target vehicle includes a vehicle running according to a route in a running scheduling plan, and the target path includes a running route set according to the running scheduling plan, which is not limited here.
[0053] The operation state information includes the target vehicle number, the running speed, the running position, the running mileage, and the operation state information of each component on the target vehicle, wherein the operation state information of each component on the target vehicle includes the operation parameters of key components such as the pantograph and the running part.
[0054] The target position is located on the target path, and the distance between the target position and the running position is greater than the line-of-sight range.
[0055] The first operation environment information includes operation state information of the target vehicle at the current position, and further includes voltage state, track state and tunnel state information of the catenary corresponding to the operation position. Similarly, the second operation environment information includes operation state information at the target position, and further includes voltage state, track state and tunnel state information of the catenary corresponding to the target position.
[0056] Different operation environments will produce different environmental fluctuations, which will affect the operation state of the vehicle. Therefore, the type of existing operation environment fluctuation can be determined according to the first operation environment information of the current position and the second operation environment information of the target position, and the operation strategy of the vehicle can be adjusted accordingly.
[0057] According to an embodiment of the present disclosure, the passenger state information in the vehicle compartment includes the number of passengers in the vehicle compartment, the crowdedness in the vehicle compartment, the physical condition of the passengers in the vehicle compartment, and the special needs of the passengers in the vehicle compartment.
[0058] For the healthy and long-term development of rail transit, passenger service level and ride experience are important evaluation indexes. When performing operation scheduling of the vehicle, the actual ride situation and individualized ride needs of passengers are considered, and the formulated vehicle operation scheduling and control strategy can effectively improve the passenger service level and ride experience. Therefore, the vehicle operation strategy generation method in the present disclosure is determined by obtaining the passenger state information in the vehicle compartment and the type of operation environment fluctuation, so as to provide passengers with safer and more comfortable ride experience.
[0059] According to an embodiment of the present disclosure, after receiving the operation state information of the vehicle, the passenger state information and the operation environment information within the visual range, the operation environment information outside the visual range is obtained, the type of operation environment fluctuation when the vehicle is running is determined based on the above information, the vehicle operation strategy is determined according to different types of operation environment fluctuation, considering the state and needs of passengers, so that the target vehicle can be processed in time and accurately after the occurrence of environmental fluctuation, and the stable operation of the vehicle can be ensured under the condition of meeting the needs of passengers, thereby improving the safety of vehicle operation and improving the ride experience of passengers.
[0060] According to an embodiment of the present disclosure, the running environment fluctuation information is generated according to the second running environment information and the first running environment information, including: in response to a difference between the voltage state of the first catenary corresponding to the current position and the voltage state of the second catenary corresponding to the target position being greater than a predetermined voltage fluctuation threshold, determining that the environment fluctuation type is catenary voltage fluctuation; in response to a difference between the smooth state of the first track corresponding to the current position and the smooth state of the second track corresponding to the target position being greater than a predetermined track fluctuation threshold, determining that the environment fluctuation type is track state fluctuation; and in response to a difference between the first tunnel state corresponding to the current position and the second tunnel state corresponding to the target position being greater than a predetermined state threshold, determining that the environment fluctuation type is tunnel state fluctuation.
[0061] According to an embodiment of the present disclosure, the voltage state of the catenary is different according to the track type. For a rail vehicle, the voltage level of the catenary is generally single-phase power frequency alternating current between 25KV and 30KV. When the train is running, the voltage of the catenary may be affected by various factors and fluctuate, for example, the vehicle requires a large starting power when starting and running, which will cause a large voltage drop of the catenary and the traction station bus. This sudden change in load will cause voltage fluctuation. In order to ensure the normal operation of the train and the safety of passengers, the voltage of the catenary must be kept within a certain stable range. Therefore, according to the relationship between the difference between the voltage state of the catenary at the current position of the train and the voltage state at the target position of the train and the voltage fluctuation threshold, it can be determined whether there is a large voltage fluctuation of the catenary that affects the train, and then a targeted operation strategy is provided.
[0062] Figure 3A An example flowchart for determining that the environment fluctuation type is catenary voltage fluctuation according to an embodiment of the present disclosure is schematically shown.
[0063] As shown in Figure 3A According to the voltage state 3211 of the catenary at the current position a of the train and the voltage state 3212 of the catenary at the target position b, the voltage state difference value X 3213 is determined, and then the voltage fluctuation value Y 3214 is generated. The relationship between the voltage fluctuation value Y 3214 and the predetermined voltage fluctuation threshold M 3215 is compared. When the voltage fluctuation value Y is greater than the predetermined voltage fluctuation threshold M, it is determined that the environment fluctuation type is catenary voltage fluctuation 3216.
[0064] According to embodiments of this disclosure, the track state refers to the overall condition and operational status of the track system during train operation, including the track's smoothness and electrical condition. The track's smoothness can be determined by its geometric and strength properties. For example, a smooth track state could be a track inclination of 15° at position p, or the track at position p could withstand a vehicle speed of 150 km / h. When the track has a good smoothness, it ensures that the train maintains a stable running trajectory during operation, reducing vibration and swaying caused by changes in the track's smoothness.
[0065] Figure 3B An example flowchart illustrating the determination of environmental fluctuation type as orbital state fluctuation according to an embodiment of the present disclosure is shown.
[0066] like Figure 3B As shown, based on the smoothness state 3221 of the track at the current position a of the train and the smoothness state 3222 of the track at the target position b, the difference value Z 3223 between the two smoothness states is determined. The relationship between the difference value Z 3223 and the predetermined track fluctuation threshold N 3224 is compared. When the difference value Z is greater than the predetermined track fluctuation threshold N, the environmental fluctuation type is determined to be track state fluctuation 3225.
[0067] According to embodiments of this disclosure, the tunnel status of a vehicle includes the length of the tunnel when it is at the target location, the tunnel structure, the wind speed and airflow pressure inside the tunnel, etc.
[0068] When a vehicle enters a tunnel, the air in front of the vehicle is compressed and cannot be expelled from the tunnel entrance in time, causing a rapid increase in pressure and creating a compression wave at the entrance. When the rear of the train enters the tunnel, the pressure behind the train drops rapidly because the air in the tunnel cannot be replenished in time, forming an expansion wave.
[0069] After a portion of the compression wave and expansion wave at the tunnel exit transforms into each other, they are reflected back towards the tunnel entrance. If the tunnel is long, the pressure waves inside will repeatedly act on the train, causing drastic changes in the train's surface pressure within a short period. If the train has poor airtightness, these drastic pressure changes outside the train will be transmitted into the interior, causing sudden pressure changes inside the train, resulting in tinnitus for passengers and affecting ride comfort. Simultaneously, due to the influence of tunnel pressure waves, the aerodynamic forces experienced by the train inside the tunnel will become unbalanced, leading to significantly more severe wear between the train wheels and rails compared to conditions of completely open track operation. Adopting inappropriate operating conditions for different tunnel conditions can seriously affect the safety, stability, and passenger experience of train operation. Therefore, adjusting the train's operating conditions according to different tunnel conditions is essential.
[0070] Figure 3CAn example flowchart of determining the environment fluctuation type as a tunnel state fluctuation according to an embodiment of the present disclosure is schematically shown.
[0071] As shown in FIG. 32, according to the tunnel state 3231 at the current position a of the train and the tunnel state 3232 at the target position b, a tunnel state difference value W 3233 is determined, and a relationship between the tunnel state difference value W 3233 and a predetermined state threshold Q 3234 is compared, when the tunnel state difference value W is greater than the predetermined state threshold Q, the environment fluctuation type is determined as a tunnel state fluctuation 3235. Figure 3C
[0072] According to an embodiment of the present disclosure, according to the voltage state of the catenary, the smoothness state of the track and the tunnel state information contained in the first and second running environment information, the state information at the current position is compared with the state information at the target position, the difference between the two is determined, and based on the relationship between the difference value and the predetermined threshold, the environment fluctuation type is determined, and then the strategy for vehicle operation is provided, the processing speed of the train operation in the face of different environmental conditions is improved, a more targeted and flexible strategy is provided, the stability and safety of the vehicle operation are improved, and the passenger's riding experience is improved.
[0073] Figure 4 An example flowchart of a vehicle operation strategy generation method when the catenary voltage fluctuates according to an embodiment of the present disclosure is schematically shown.
[0074] As shown in FIG. 32, according to the tunnel state 3231 at the current position a of the train and the tunnel state 3232 at the target position b, a tunnel state difference value W 3233 is determined, and a relationship between the tunnel state difference value W 3233 and a predetermined state threshold Q 3234 is compared, when the tunnel state difference value W is greater than the predetermined state threshold Q, the environment fluctuation type is determined as a tunnel state fluctuation 3235. Figure 4
[0075] In operation S421, in response to the environment fluctuation type being a catenary voltage fluctuation, the load state of the electrical equipment in each car is adjusted according to the passenger number distribution state in each car.
[0076] In operation S422, based on the target time when the target vehicle arrives at the target position, the vehicle flow through the target position at the target time is obtained from the train-ground integrated electromechanical system.
[0077] In operation S423, it is judged whether the vehicle flow is less than a predetermined flow threshold, when the judgment result is yes, operation S424 is executed, and when the judgment result is no, operation S425 is executed.
[0078] In operation S424, a vehicle operation strategy is generated at the current running speed and the adjusted load state of the electrical equipment in each car.
[0079] In operation S425, the current running speed is reduced, and a vehicle operation strategy is generated according to the reduced running speed and the adjusted load state of the electrical equipment in each car.
[0080] According to an embodiment of the present disclosure, voltage fluctuation can cause instability of the train power supply system, thereby affecting the power output and control system of the train, which can cause uneven acceleration, sudden deceleration or jolting of the train during travel, or even failure of the train to operate normally, thereby reducing the comfort of passengers or travel plans. Voltage fluctuation can also cause abnormal operation of devices on the train, such as lighting systems, air conditioning systems, train broadcasting systems, or information display systems, for example, flickering lights, unstable air conditioning temperature, and the like, which can directly affect the passenger experience. In extreme cases, voltage fluctuation can cause the train control system to fail or the safety device to malfunction. This can cause the train to fail to stop in time, fail to accurately control the speed, and the like, thereby increasing the safety risk of train operation.
[0081] When the power consumption equipment or power supply demand in the same period is too large, exceeding the power load that the power supply system can bear, voltage fluctuation is likely to occur. Therefore, in order to reduce or prevent catenary voltage fluctuation, the catenary voltage fluctuation can be reduced by reasonably distributing the load of the power consumption equipment and adjusting the power, thereby ensuring the stability of the power grid operation.
[0082] According to an embodiment of the present disclosure, the passenger quantity distribution state can be determined according to the crowdedness of the car, the number of passengers in the car, and the type of passengers, including the uniformity of the distribution, the density of the distribution, and the group of the distribution. When voltage fluctuation occurs, the load state of the power consumption equipment in each car can be adjusted according to the passenger quantity distribution state in the car, so as to reduce the power consumption load of the target vehicle, thereby reducing the voltage fluctuation. For example, the passenger quantity distribution state in the x car is obtained as follows: the front section of the car is unevenly distributed, the passenger density is large, the passenger type is mainly young adults, the middle section of the car is evenly distributed, the passenger density is moderate, and the passenger type is women, and the rear section of the car is unevenly distributed, the passenger density is low, and the passenger type is young. According to the above passenger quantity distribution state in the car, the intensity and number of air conditioning and lighting equipment in the middle and rear sections of the car can be reduced.
[0083] According to an embodiment of the present disclosure, when the vehicle flow is large in the same period, the required electric energy of the vehicle can reach a large peak value. Therefore, at the target time, the vehicle running speed can be adjusted according to the relationship between the vehicle flow of the target vehicle passing through the target position and the threshold value, so as to reduce the vehicle flow in the same period, thereby reducing the total power consumption and reducing voltage fluctuation. For example, the vehicle flow of vehicle y at the next station k at time t is obtained as 4 vehicles, which is greater than the predetermined flow threshold value of 3 vehicles. At this time, the running speed of vehicle y is reduced, so that the vehicle flow is less than the threshold value when passing through the next station k at time t.
[0084] According to an embodiment of the present disclosure, based on the passenger quantity distribution state obtained from the vehicle-ground integrated electromechanical system and the vehicle flow of the target position at the target time, the load state of the electrical equipment in each car and the running speed of the vehicle are adjusted, the total power consumption of the vehicle running is reduced, the voltage fluctuation is reduced, the stability and safety of the vehicle running are improved, and the passenger riding experience is improved while meeting the passenger demand and the normal running scheduling of the vehicle.
[0085] According to an embodiment of the present disclosure, based on the running environment fluctuation type and the passenger state information in each car, the running state information of each component is adjusted to generate a vehicle running strategy, including: in response to the running environment fluctuation type being a geometric property fluctuation and a strength fluctuation of the track, a first speed reduction strategy is generated according to the current running speed, the distance between the target position and the current position, and the physical state of the passengers; and the running state of the traction component of the target vehicle is adjusted based on the first speed reduction strategy, so that the target vehicle slows down and smoothly passes through the damaged track.
[0086] According to an embodiment of the present disclosure, the track state fluctuation of the track includes a geometric property fluctuation and a strength fluctuation of the track. The geometric property of the track includes the straightness of the track, the bending curvature and its uniformity of the track curve radius, the track gauge constancy, etc. The strength property of the track includes the size of the vehicle running speed and pressure that the track can withstand after the track surface has pits, bumps or uneven wear due to long-time running. When the geometric property fluctuation and the strength fluctuation of the track occur, the vehicle often needs to reduce the running speed, for example, the track of the front section has been used for a long time, and the track surface is severely worn, so the running speed it can withstand is less than the running speed at the current position, and speed reduction processing is needed.
[0087] For passengers with special diseases, such as acute coronary syndrome, when facing a sharp decrease in vehicle running speed, the passenger's symptoms may worsen, so a reasonable speed reduction strategy needs to be generated according to the current running speed, the distance between the target position and the current position, and the physical state of the passengers.
[0088] According to an embodiment of the present disclosure, the first speed reduction strategy can be a stepwise speed reduction, that is, maintaining a certain speed for a period of time and then reducing the speed, and so on, to achieve smooth speed reduction. The first speed reduction strategy can also be a uniform speed reduction, that is, reducing the speed at a constant acceleration to ensure smooth running of the vehicle.
[0089] The running state of the traction component includes the running parameters of the key components of the vehicle traction transmission system, such as the voltage and frequency of the traction inverter. By controlling the running parameters of the key traction components, the running speed and state of the vehicle can be effectively controlled.
[0090] According to the embodiment of the present disclosure, when the vehicle appears a running environment fluctuation of a tunnel state fluctuation, a safe and humanized speed reduction strategy can be generated according to the current running speed, the distance between the target position and the current position, and the passenger body state, so that the target vehicle slows down and smoothly passes through the tunnel, improves the safety and stability of the vehicle running, and improves the passenger riding experience.
[0091] Figure 5 A flowchart of a vehicle running strategy generation method in a tunnel state fluctuation according to an embodiment of the present disclosure is schematically shown.
[0092] As shown in Figure 5 The method 500 includes operations S521-S526.
[0093] In operation S521, in response to the running environment fluctuation type being a tunnel state fluctuation, the resistance generated by the change of air in the tunnel to the running of the target vehicle when the target vehicle reaches the tunnel located at the target position is calculated according to the current running speed.
[0094] In operation S522, it is judged whether the resistance is less than a predetermined resistance threshold value, and when the judgment result is yes, operation S523 is performed, and when the judgment result is no, operation S524 is performed.
[0095] In operation S523, the target running speed is calculated according to the predetermined resistance threshold value.
[0096] In operation S524, the target vehicle smoothly passes through the front track at the current running speed.
[0097] In operation S525, a second speed reduction strategy is generated according to the current running speed, the target running speed, the passenger state information in each car, and the distance between the target position and the current position.
[0098] In operation S526, the running state of the traction component of the target vehicle is adjusted based on the second speed reduction strategy, so that the target vehicle slows down and smoothly passes through the front tunnel.
[0099] According to the embodiment of the present disclosure, the vehicle running in the tunnel is the most complex and severe running condition, and the surface pressure amplitude of the train in the tunnel is much larger than that of the train running in the open line. When the vehicle runs in the tunnel, the change of air in the tunnel generates different resistance to the running of the vehicle. When the resistance is too large, the larger running speed will cause greater damage to the surface components of the vehicle, and may cause unpredictable risks. At the same time, when the resistance is too large, the larger running speed will generate strong air flow, causing the vehicle to vibrate, the noise is large, and the riding experience is not good. Therefore, it is necessary to calculate the resistance generated by the vehicle running according to the change of air in the tunnel, and generate a corresponding speed reduction strategy.
[0100] The second speed reduction strategy is determined based on the current running speed, the target running speed, the passenger state information in each carriage and the distance between the target position and the current position, and includes a stepwise speed reduction and a uniform speed reduction.
[0101] According to the embodiment of the present disclosure, when the running environment fluctuation type is a tunnel state fluctuation, the resistance to the running of the target vehicle caused by the change of the air in the tunnel when the target vehicle reaches the tunnel located at the target position is calculated according to the current running speed, and compared with a predetermined resistance threshold value, when the resistance is greater than the predetermined resistance threshold value, the target running speed is calculated, and a reasonable speed reduction strategy is generated according to the current running speed, the target running speed, the passenger state information in each carriage and the distance between the target position and the current position. The above-mentioned speed reduction strategy takes into account the specific situation of different tunnels, and also takes into account the state of the passengers, ensuring that the vehicle can run smoothly when entering and leaving the tunnel, and improving the passenger's riding experience.
[0102] Figure 6 A flowchart of a method for generating a vehicle running strategy according to the condition of a component according to an embodiment of the present disclosure is schematically shown.
[0103] As shown in Figure 6 , the method 600 includes operations S601-S605.
[0104] In operation S601, maintenance record information of each component of the target vehicle is obtained.
[0105] In operation S602, the fatigue resistance degree of each component is generated according to the running state information and the maintenance record information of each component.
[0106] In operation S603, it is judged whether the fatigue resistance degree is less than a predetermined threshold value, when the judgment result is yes, operation S604 is executed, and when the judgment result is no, operation S605 is executed.
[0107] In operation S604, fault warning information is sent to the vehicle-ground integrated electromechanical system and the running speed is reduced.
[0108] In operation S605, the vehicle is run according to the predetermined vehicle running strategy.
[0109] According to the embodiment of the present disclosure, the maintenance record information of each component includes the number of times of maintenance of each component, the time of maintenance, the expected use time after maintenance and the like.
[0110] According to the operation state information and the maintenance record information of each component, the fatigue resistance degree of each component can be calculated by comprehensively calculating the use score of the component based on the operation state information and the maintenance record information of each component, and determining the fatigue resistance degree of the component according to the corresponding relationship between the component use score and the fatigue resistance degree grade of each component, for example, the component x has been running for 5 years and has been maintained for 3 times, and the corresponding fatigue resistance degree grade is level 2. The fatigue resistance degree of each component can also be calculated by inputting the operation state information and the maintenance record information of each component into a mathematical model, wherein the mathematical model can be obtained by training a neural network model.
[0111] When the fatigue resistance degree is less than the fatigue resistance degree required by each component corresponding to the resistance, it indicates that the component cannot cope with the subsequent environmental fluctuation, which is likely to cause a larger vehicle operation danger. At this time, the fault warning information needs to be sent to the vehicle-ground integrated electromechanical system and the running speed needs to be reduced, so that the target vehicle stops before reaching the target position.
[0112] According to the embodiments of the present disclosure, by obtaining the operation state information and the maintenance record information of each component, the fatigue resistance degree of each component is determined, and the current operation scheme is evaluated based on the obtained fatigue resistance degree in the face of the environmental fluctuation, if the safe operation condition is not met, the fault warning information is sent to the vehicle-ground integrated electromechanical system to solve the possible safety hazard and improve the safety of vehicle operation.
[0113] Figure 7 The flowchart of the method for generating a vehicle operation strategy according to the foreign object intrusion situation according to the embodiments of the present disclosure is schematically shown.
[0114] As shown in Figure 7 , the method 700 includes operations S701-S705.
[0115] In operation S701, in response to receiving foreign object intrusion track information from a target position, the foreign object moving speed and the foreign object moving direction are extracted from the foreign object intrusion track information.
[0116] In operation S702, the probability of collision between the target vehicle and the foreign object is determined according to the foreign object moving direction, the foreign object moving speed and the current running state of the target vehicle.
[0117] In operation S703, it is judged whether the probability is greater than a predetermined probability threshold, when the judgment result is yes, operation S704 is executed, and when the judgment result is no, operation S705 is executed.
[0118] In operation S704, the running state of the traction component of the target vehicle is adjusted.
[0119] In operation S705, the vehicle is operated according to a predetermined vehicle operation strategy.
[0120] According to an embodiment of the present disclosure, the foreign matter invading the track is one of the sudden situations that often occur when the vehicle is running. Since the foreign matter has a certain speed, if it collides with the running vehicle, it will cause unpredictable loss and harm. Therefore, when the foreign matter invades the track, the foreign matter invasion information needs to be known in advance to generate an effective vehicle running strategy for this situation.
[0121] The foreign matter invading the track information is obtained through the vehicle-ground integrated electromechanical system. The key information of the foreign matter invading the track information includes the foreign matter moving speed and the foreign matter moving direction. According to the foreign matter moving direction, the foreign matter moving speed and the current running state of the target vehicle, the probability of the target vehicle colliding with the foreign matter can be determined. If the collision probability is greater than a threshold value, the running state of the traction component of the target vehicle needs to be adjusted to reduce the vehicle running speed, change the vehicle running route or stop the vehicle running.
[0122] For example, at time t, the vehicle x is about to run to position z. At this time, the foreign matter invading the track information of position z is that a bird passes above the track of position z at a moving speed of a. According to the above information, the probability of the vehicle colliding with the bird is 2%, which is greater than the predetermined threshold value 0.01%. At this time, the running state of the traction component of the target vehicle is adjusted to reduce the running speed of the target vehicle until the probability is less than the predetermined probability threshold value.
[0123] According to an embodiment of the present disclosure, by timely obtaining the foreign matter invading the track information from the target position, extracting the foreign matter moving speed and the foreign matter moving direction, and then calculating the probability of the target vehicle colliding with the foreign matter, the relationship between the probability of the target vehicle colliding with the foreign matter and the probability threshold value is judged. The running state of the traction component of the vehicle is timely adjusted to avoid the occurrence of the vehicle colliding with the foreign matter event and the occurrence of the dangerous accident, improve the safety of the vehicle running, and because the foreign matter in the beyond-visual-range is perceived in advance and the strategy is adjusted, not only the risk existing when the vehicle is running is reduced, but also the perception of the passengers to the abnormal situation is reduced, further improving the passenger riding experience.
