[0002] At present, the road condition information detected by sensors on the track ahead when rail vehicles are running is very limited. For example, it is difficult for rail vehicles to obtain track condition information and power supply status in the track ahead in a timely and accurate manner. Therefore, when faced with changes in the operating environment, rail vehicles usually adopt various emergency control strategies to cope with changes in the operating environment, which reduces the safety and stability of rail vehicle operation, affects passengers' riding experience, and increases uncertainty and risk in the journey.

[0029] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0030] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0031] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0032] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0033] In the embodiments of the present disclosure, the collection, updating, analysis, processing, use, transmission, provision, disclosure, storage, etc. of the data involved (for example, including but not limited to user personal information) are in compliance with the provisions of relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. In particular, necessary measures are taken for user personal information to prevent illegal access to user personal information data and maintain the security of user personal information, network security, and national security.

[0034] In the embodiments of the present disclosure, the user's authorization or consent is obtained before obtaining or collecting the user's personal information.

[0035] When rail vehicles are in operation, there are often many restrictions due to the limited information the vehicles themselves can obtain. At present, when the vehicle is in operation, it is impossible to fully and in real time understand the specific conditions of the operation of the road section ahead. For example, due to the limitation of the line of sight range, the vehicle cannot obtain information about foreign objects and track conditions on the track ahead, making it impossible for the vehicle to accurately and effectively handle abnormal operating environment conditions. For example, because the vehicle cannot obtain the operating status information of other vehicles in the same period in a timely manner, the power supply system may exceed the load it can bear during vehicle operation and management, which in turn causes large fluctuations in the voltage of the power supply system, seriously affecting the operation of the vehicle. When the vehicle responds to sudden changes in the operating environment in a short period of time, emergency measures are usually required, which can easily cause panic among passengers and reduce the passenger experience.

[0036] When rail vehicles face the above-mentioned emergencies, due to the limitations of the above-mentioned information, they may experience emergency deceleration or braking, which reduces the safety and stability of rail vehicle operation. At the same time, the above-mentioned operation adjustment strategy does not take into account the needs of passengers, which seriously affects the passengers' riding experience and increases the uncertainty and risk in the journey.

[0037] In view of this, the embodiments of the present disclosure provide for obtaining operating environment information outside the visual range after receiving the vehicle's operating status information, passenger status information and operating environment information within the visual range, and determining the type of operating environment fluctuations during vehicle operation based on the above information, and determining the vehicle operation strategy according to the different types of operating environment fluctuations while taking into account the passenger's status and needs, so that the target vehicle can adjust the operation strategy in a timely and accurate manner after the occurrence of environmental fluctuations, and at the same time ensure stable operation of the vehicle while meeting the passenger's needs, thereby improving the safety of vehicle operation, reducing the passenger's perception of operating environment fluctuations, and improving the passenger's riding experience.

[0038] The vehicle-ground integrated electromechanical system integrates rail vehicles, ground infrastructure and cloud services to achieve real-time monitoring of vehicle operating status and information sharing. It can be applied to the intelligent operation control and management of rail vehicles.

[0039] Figure 1 The system architecture diagram of the vehicle-ground integrated electromechanical system applicable to the vehicle operation strategy generation method according to the embodiment of the present disclosure is schematically shown. It should be noted that: Figure 1What is shown is merely an example of a system architecture to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0040] like Figure 1 As shown, according to this embodiment, the vehicle-ground integrated electromechanical system architecture 100 includes a vehicle system 101, a vehicle-ground collaborative power supply system 102, an on-board engineering detection system 103, a vehicle-ground collaborative inspection and maintenance system 104, and a vehicle-ground collaborative passenger service system 105, wherein the vehicle includes a vehicle network control system TCMS subsystem 101-1, an on-board PHM 101-2, an on-board network track detection subsystem 101-3 and an on-board PIS subsystem 101-4.

[0041] The vehicle network control TCMS subsystem 101-1 can obtain information such as the vehicle's location and vehicle operation status in real time. The vehicle-ground cooperative power supply system 102 can adjust the vehicle's power supply in real time based on the network communication with the vehicle network control TCMS subsystem 101-1, provide the vehicle with traction force adapted to its operation status, and adjust the operation status of the traction components of the vehicle system 101 to meet the vehicle system 101 to run at the target speed.

[0042] The on-board maintenance detection system 103 includes detection of track state information such as track geometry parameters and track wear conditions, as well as detection of tunnel state information such as tunnel surface and tunnel air changes, and detection of contact network state information such as contact network geometry parameters and contact network voltage fluctuations. The above detection can collect relevant images through sensors, and perform image recognition or obtain detection results through real-time testing of intelligent devices. The on-board maintenance detection system 103 can communicate with the on-board network track detection subsystem 101-3 through the network, so that the vehicle system 101 can obtain the vehicle's operating environment information in real time, and then determine the fluctuation of the operating environment. The on-board maintenance detection system 103 can also send foreign object intrusion track information to the on-board network track detection subsystem 101-3, and detect and send danger warning information beyond the sight range of the vehicle system 101 in real time.

[0043] The vehicle-ground collaborative inspection and maintenance system 104 can communicate with the on-board PHM 101 - 2 over the network to obtain important fault data of the train in real time. The vehicle system 101 can also obtain maintenance record information of various vehicle components through network communication between the vehicle-ground collaborative inspection and maintenance system 104 .

[0044] The vehicle-ground cooperative passenger service system 105 can obtain real-time video surveillance images, congestion detection information, passenger quantity information and other information in the vehicle compartment through network communication with the vehicle-mounted PIS subsystem 101-4, and send early warning broadcast information to the vehicle-mounted PIS subsystem 101-4. At the same time, the vehicle-mounted PIS subsystem can obtain passenger identity information, passenger physical condition and other information through communication.

[0045] The above-mentioned vehicle-ground integrated electromechanical system realizes real-time communication and data interaction between the vehicle and the ground, providing a good information basis for determining the vehicle operation strategy under different situations.

[0046] It should be understood that Figure 1 The number of system modules in the embodiment is only for illustration. According to the implementation requirements, there may be any number and functions of system modules.

[0047] Figure 2 A flow chart of a method for generating a vehicle operation strategy based on a vehicle-ground integrated electromechanical system according to an embodiment of the present disclosure is schematically shown.

[0048] like Figure 2 As shown, the method 200 includes operations S210 to S230.

[0049] In operation S210, in response to receiving the operating status information of the target vehicle on the target path, the passenger status information in each compartment of the target vehicle and the first operating environment information within the sight range; the second operating environment information within the sight range when the target vehicle is at the target position is obtained.

[0050] In operation S220, the operating environment fluctuation type is determined according to the second operating environment information and the first operating environment information.

[0051] In operation S230, a vehicle operation strategy is generated by adjusting the operation status information of each component based on the operation environment fluctuation type and the passenger status information in each compartment.

[0052] According to an embodiment of the present disclosure, the target vehicle includes a vehicle running according to a route in an operation scheduling plan, and the target path includes an operation route set according to the operation scheduling plan, which is not limited here.

[0053] The operating status information includes the target vehicle number, operating speed, operating position, operating mileage and operating status information of each component on the target vehicle, among which the operating status information of each component on the target vehicle includes operating parameters of key components such as pantographs and running gear.

[0054] The target position is on the target path, and the distance between the target position and the operating position is greater than the line of sight range.

[0055] The first operating environment information includes the operating state information of the target vehicle at the current position, and also includes the voltage state, track state and tunnel state information of the overhead contact network corresponding to the operating position. Similarly, the second operating environment information includes the operating state information at the target position, and the voltage state, track state and tunnel state information of the overhead contact network corresponding to the target position.

[0056] Different operating environments will produce different environmental fluctuations, which will affect the operating status of the vehicle. Therefore, the type of operating environment fluctuations can be determined based on the first operating environment information at the current location and the second operating environment information at the target location, and the vehicle's operating strategy can be adjusted in a targeted manner.

[0057] According to an embodiment of the present disclosure, the passenger status information in the carriage includes information such as the number of passengers in the carriage, the degree of congestion in the carriage, the physical conditions of the passengers in the carriage, and the special needs of the passengers in the carriage.

[0058] For the healthy and long-term development of rail transit, passenger service level and riding experience are important evaluation indicators. When scheduling vehicle operations, the vehicle operation scheduling and control strategies formulated while taking into account the actual riding conditions and personalized riding needs of passengers can effectively improve the passenger service level and riding experience. Therefore, the vehicle operation strategy generation method disclosed in the present invention is determined by obtaining the passenger status information in the car and the type of operating environment fluctuations, so as to provide passengers with a safer and more comfortable riding experience.

[0059] According to the embodiments of the present disclosure, after receiving the vehicle's operating status information, passenger status information and operating environment information within the line of sight range, the operating environment information outside the line of sight range is obtained, and based on the above information, the type of operating environment fluctuation during vehicle operation is determined. According to the different types of operating environment fluctuations, the passenger's status and needs are taken into consideration to determine the vehicle operation strategy, so that the target vehicle can handle environmental fluctuations in a timely and accurate manner, and at the same time can ensure stable operation of the vehicle while meeting passenger needs, thereby improving the safety of vehicle operation and improving the passenger's riding experience.

[0060] According to an embodiment of the present disclosure, operating environment fluctuation information is generated based on the second operating environment information and the first operating environment information, including: in response to the difference between the voltage state of the first contact network corresponding to the current position and the voltage state of the second contact network corresponding to the target position being greater than a predetermined voltage fluctuation threshold, determining that the type of environmental fluctuation is contact network voltage fluctuation; in response to the difference between the smoothness state of the first track corresponding to the current position and the smoothness state of the second track corresponding to the target position being greater than a predetermined track fluctuation threshold, determining that the type of environmental fluctuation is track state fluctuation; and in response to the 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 type of environmental fluctuation is tunnel state fluctuation.

[0061] According to the embodiments of the present disclosure, the voltage state of the contact network varies according to the type of track. For rail vehicles, the voltage level of the contact network is generally a single-phase industrial frequency alternating current between 25KV and 30KV. When the train is running, the voltage of the contact network may fluctuate due to various factors. For example, when the vehicle is starting and running, it requires a large starting power, which will cause a large voltage drop in the contact network and the traction station bus. This sudden change in load will cause voltage fluctuations. In order to ensure the normal operation of the train and the safety of passengers, the voltage of the contact network must be maintained within a certain stable range. Therefore, based on the relationship between the difference between the voltage state of the contact network 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 voltage fluctuation with a large impact on the contact network at this time, and then a targeted operation strategy can be provided.

[0062] Figure 3A An example flowchart for determining that the type of environmental fluctuation is overhead line voltage fluctuation according to an embodiment of the present disclosure is schematically shown.

[0063] like Figure 3A As shown, according to the overhead contact network voltage state 3211 at the current position a of the train and the overhead contact network voltage state 3212 at the target position b, the voltage state difference value X 3213 is determined, and then the voltage fluctuation value Y 3214 is generated, and the relationship between the voltage fluctuation value Y 3214 and the predetermined voltage fluctuation threshold value M 3215 is compared. When the voltage fluctuation value Y is greater than the predetermined voltage fluctuation threshold value M, it is determined that the environmental fluctuation type is overhead contact network voltage fluctuation 3216.

[0064] According to the embodiments of the present disclosure, the track state of the train is the overall condition and working condition of the track system during the running of the train, including the smoothness state and electrical state of the track, wherein the smoothness state of the track can be determined by the geometric properties and strength properties of the track, for example, the smoothness state of the track can be that the track inclination at position p is 15°, or that the vehicle running speed that the track at position p can withstand is 150km / h. When the track has a good smoothness state, it can ensure that the train maintains a stable running track during the running process, and reduce the vibration and shaking of the track caused by the change of the smoothness state.

[0065] Figure 3B An example flowchart for determining that the type of environmental fluctuation is a track state fluctuation according to an embodiment of the present disclosure is schematically shown.

[0066] like Figure 3B As shown, according to 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 smoothness state difference value Z 3223 between the two is determined, and the relationship between the smoothness state difference value Z 3223 and the predetermined track fluctuation threshold value N 3224 is compared. When the smoothness state difference value Z is greater than the predetermined track fluctuation threshold value N, the environmental fluctuation type is determined to be track state fluctuation 3225.

[0067] According to an embodiment of the present disclosure, the tunnel state of the vehicle includes the length of the tunnel when at the target position, the structure of the tunnel, the wind speed and airflow pressure in the tunnel, etc.

[0068] When a vehicle enters a tunnel, the air in front of the vehicle is squeezed and has no time to be discharged from the tunnel entrance, so the pressure rises sharply and a compression wave is generated at the entrance; when the rear of the train enters the tunnel, the air behind the train has no time to be replenished in the tunnel, so the pressure drops sharply and an expansion wave is formed.

[0069] At the tunnel exit, a part of the compression wave and expansion wave transforms into each other and reflects back to propagate toward the tunnel entrance. If the tunnel is relatively long, the pressure wave in the tunnel will repeatedly act on the train, causing the surface pressure of the train to change dramatically in a short period of time. If the air tightness of the train is poor, the drastic pressure change outside the car will be transmitted into the car, causing a sudden change in the pressure inside the car, causing tinnitus in the passengers and affecting the riding comfort. At the same time, affected by the tunnel pressure wave, the aerodynamic force on the train in the tunnel will be unbalanced, resulting in much more serious wear between the wheels and rails of the train than under the condition of full open line operation. In the face of different tunnel conditions, adopting an inappropriate operating state will seriously affect the safety and stability of the vehicle operation and the riding experience of passengers. Therefore, it is very necessary to adjust the operating state of the vehicle according to different tunnel conditions.

[0070] Figure 3CAn example flowchart for determining that the type of environmental fluctuation is tunnel state fluctuation according to an embodiment of the present disclosure is schematically shown.

[0071] like Figure 3C As shown, according to the tunnel state 3231 of the current position a of the train and the tunnel state 3232 of the target position b, the tunnel state difference value W 3233 is determined, and the relationship between the tunnel state difference value W 3233 and the predetermined state threshold Q 3234 is compared. When the tunnel state difference value W is greater than the predetermined state threshold Q, the environmental fluctuation type is determined to be tunnel state fluctuation 3235.

[0072] According to an embodiment of the present disclosure, based on the voltage state of the contact network, the smoothness state of the track and the tunnel state information contained in the second operating environment information and the first operating environment information, the state information of the current position is compared with the state information of the target position to determine the difference between the two, and based on the relationship between the difference value and the predetermined threshold, the type of environmental fluctuation is determined, and then targeted vehicle operation strategies are provided to improve the processing speed of trains in the face of different environmental conditions during operation, provide more targeted and flexible strategies, improve the stability and safety of vehicles during operation, and improve the riding experience of passengers.

[0073] Figure 4 A flow chart of a method for generating a vehicle operation strategy when the overhead line voltage fluctuates according to an embodiment of the present disclosure is schematically shown.

[0074] like Figure 4 As shown, the method 400 includes operations S421-S425.

[0075] In operation S421, in response to the environmental fluctuation type being overhead line voltage fluctuation, the load state of the electrical equipment in each compartment is adjusted according to the distribution state of the number of passengers in each compartment.

[0076] In operation S422 , based on the target time at which the target vehicle arrives at the target location, the vehicle flow passing through the target location at the target time is acquired from the vehicle-ground integrated electromechanical system.

[0077] In operation S423, it is determined whether the vehicle flow rate is less than a predetermined flow rate threshold. When the determination result is yes, operation S424 is performed, and when the determination result is no, operation S425 is performed.

[0078] In operation S424, a vehicle operation strategy is generated based on the current operating speed and the adjusted load status of the electrical equipment in each compartment.

[0079] In operation S425, the current operating speed is reduced, and a vehicle operating strategy is generated according to the reduced operating speed and the adjusted load state of the electrical equipment in each compartment.

[0080] According to the embodiments of the present disclosure, voltage fluctuations may cause instability in the train power supply system, thereby affecting the power output and control system of the train, which may cause uneven acceleration, abrupt deceleration or bumps, or even failure to operate normally during the train's travel, thereby reducing passengers' riding comfort or travel plans. Voltage fluctuations may also cause abnormal operation of equipment such as the lighting system, air-conditioning system, train broadcasting system or information display system on the train, for example, flickering lighting, unstable air-conditioning temperature, etc., which will directly affect the passengers' riding experience. In extreme cases, voltage fluctuations may cause the train control system to fail or the safety device to malfunction. This may cause the train to be unable to stop in time, unable to accurately control the speed, etc., thereby increasing the safety risk of train operation.

[0081] When the demand for electrical equipment or power supply is too large in the same period, exceeding the power load that the power supply system can bear, voltage fluctuations are very likely to occur. Therefore, in order to reduce or prevent contact network voltage fluctuations, load distribution and power regulation of electrical equipment can be reasonably performed to reduce contact network voltage fluctuations and ensure the stability of power grid operation.

[0082] According to the embodiments of the present disclosure, the distribution state of the number of passengers can be determined based on the crowdedness of the carriage, the number of passengers in the carriage, and the type of passengers, including the uniformity of distribution, the density of distribution, and the group nature of distribution. When voltage fluctuations occur, the load state of the electrical equipment in each carriage can be adjusted in a targeted manner according to the distribution state of the number of passengers in the carriage to reduce the power load of the target vehicle, thereby reducing voltage fluctuations. For example: the distribution state of the number of passengers in carriage x is obtained as follows: the distribution in the front section of the carriage is uneven, the density of passengers is large, and the passenger types are mainly young and middle-aged people; the distribution in the middle section of the carriage is uniform, the density of passengers is moderate, and the passenger types are women; the distribution in the rear section of the carriage is uneven, the density of passengers is low, and the passenger types are young people. According to the above-mentioned distribution state of the number of passengers in the carriage, the intensity and number of air-conditioning and lighting equipment in the middle and rear sections of the carriage can be reduced.

[0083] According to the embodiments of the present disclosure, when the vehicle flow is large in the same time period, the electric energy required by the vehicle will 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 the target location and the threshold value to reduce the vehicle flow in the same time period, thereby reducing the total power consumption and reducing voltage fluctuations. For example: the vehicle flow of vehicle y at the next station k at time t is 4 vehicles, which is greater than the predetermined flow threshold 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 the next station k at time t.

[0084] According to the embodiments of the present disclosure, based on the passenger quantity distribution status obtained from the vehicle-ground integrated electromechanical system and the vehicle flow passing the target location at the target time, the load status of the electrical equipment in each car and the running speed of the vehicle are adjusted. While satisfying the passenger needs and the normal operation scheduling of the vehicle at the same time, the total power load of the vehicle operation is reduced, the voltage fluctuation is reduced, the stability and safety of the vehicle operation are improved, and the passenger riding experience is improved.

[0085] According to an embodiment of the present disclosure, based on the operating environment fluctuation type and the passenger status information in each car, a vehicle operation strategy is generated by adjusting the operating status information of each component, including: in response to the operating environment fluctuation type being the geometric property fluctuation and intensity fluctuation of the track, a first deceleration strategy is generated according to the current operating speed, the distance between the target position and the current position, and the physical state of the passenger; and based on the first deceleration strategy, the operating state of the traction components of the target vehicle is adjusted so that the target vehicle decelerates slowly and passes smoothly through the damaged track.

[0086] According to an embodiment of the present disclosure, the track state fluctuation of the track includes the geometric property fluctuation and strength fluctuation of the track. The geometric properties of the track include the straightness of the track, the curvature of the track curve radius and its uniformity, the constancy of the track gauge, etc. The strength properties of the track include the vehicle running speed and pressure that the track can withstand after the track has potholes, bumps or uneven wear on the track surface due to long-term operation. When the geometric property fluctuation and strength fluctuation of the track occur, the vehicle often needs to reduce the running speed. For example, when the track of the current section of the road has been in use for a long time and the track surface is severely worn, the running speed it can withstand is less than the running speed at the current position, and the speed reduction process is required.

[0087] For passengers with special diseases, such as acute coronary syndrome, their symptoms may be aggravated when faced with a sharp drop in vehicle speed. Therefore, it is necessary to generate a reasonable speed reduction strategy based on the current running speed, the distance between the target location and the current location, and the physical condition of the passenger.

[0088] According to an embodiment of the present disclosure, the first deceleration strategy can be a step-by-step deceleration, that is, maintaining a specific speed for a period of time and then reducing the speed, and so on, to achieve smooth deceleration. The first deceleration strategy can also be a uniform deceleration, that is, decelerating at a constant acceleration to ensure smooth operation of the vehicle.

[0089] The operating status of the traction components includes the operating parameters of the key components of the vehicle's traction drive system, such as the voltage and frequency of the traction inverter. By controlling the operating parameters of the key traction components, the vehicle's operating speed and operating status can be effectively controlled.

[0090] According to the embodiments of the present disclosure, when the operating environment fluctuations of the vehicle are such as fluctuations in the geometric properties and intensity of the track, a safe and humane deceleration strategy can be generated based on the current operating speed, the distance between the target position and the current position, and the physical condition of the passengers, so that the target vehicle can slowly decelerate and pass through the track smoothly, thereby improving the safety and stability of the vehicle during operation and enhancing the riding experience of the passengers.

[0091] Figure 5 A flow chart of a method for generating a vehicle operation strategy when a tunnel state fluctuates according to an embodiment of the present disclosure is schematically shown.

[0092] like Figure 5 As shown, the method 500 includes operations S521 to S526.

[0093] In operation S521, in response to the operating environment fluctuation type being tunnel state fluctuation, the resistance generated by the change of air in the tunnel on the operation of the target vehicle when the target vehicle reaches the tunnel at the target position is calculated according to the current operating speed.

[0094] In operation S522, it is determined whether the resistance is less than a predetermined resistance threshold. When the determination result is yes, operation S523 is performed, and when the determination result is no, operation S524 is performed.

[0095] In operation S523, a target running speed is calculated according to a predetermined resistance threshold.

[0096] In operation S524, the 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 status information in each compartment, and the distance between the target position and the current position.

[0098] In operation S526, the operating state of the traction component of the target vehicle is adjusted according to the second deceleration strategy, so that the target vehicle decelerates slowly and passes through the tunnel ahead smoothly.

[0099] According to the embodiments of the present disclosure, the operation of a vehicle in a tunnel is the most complex and severe operating condition. The surface pressure amplitude of a train when operating in a tunnel is much greater than the surface pressure of a train when operating on an open line. The changes in the air in a tunnel cause different resistances to the operation of the vehicle. When the resistance is too large, a higher operating speed will cause greater damage to the surface components of the vehicle, which may result in unpredictable risks. At the same time, when the resistance is too large, a higher operating speed will generate strong airflow, causing the vehicle to be bumpy and noisy, resulting in a bad riding experience. Therefore, it is necessary to calculate the resistance generated by the operation of the vehicle according to the changes in the 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 status information in each car, and the distance between the target position and the current position, including step-by-step speed reduction and uniform speed reduction.

[0101] According to the embodiments of the present disclosure, when the operating environment fluctuation type is tunnel state fluctuation, the resistance caused by the change of air in the tunnel to the operation of the target vehicle when the target vehicle arrives at the tunnel at the target position is calculated based on the current operating speed, and compared with the predetermined resistance threshold. When the resistance is greater than the predetermined resistance threshold, the target operating speed is calculated, and a reasonable speed reduction strategy is generated based on the current operating speed, the target operating speed, the passenger status information in each car, and the distance between the target position and the current position. The above speed reduction strategy takes into account the specific conditions of different tunnels and the status of the passengers, ensuring that the vehicle can run smoothly when entering and exiting the tunnel, thereby improving the riding experience of the passengers.

[0102] Figure 6 A flowchart of a method for generating a vehicle operation strategy according to component conditions according to an embodiment of the present disclosure is schematically shown.

[0103] like Figure 6 As shown, the method 600 includes operations S601-S605.

[0104] In operation S601 , maintenance record information of each component of a target vehicle is acquired.

[0105] In operation S602, the fatigue resistance of each component is generated according to the operation status information and maintenance record information of each component.

[0106] In operation S603, it is determined whether the anti-fatigue degree is less than a predetermined threshold value. When the determination result is yes, operation S604 is performed, and when the determination result is no, operation S605 is performed.

[0107] In operation S604, fault warning information is sent to the vehicle-ground integrated electromechanical system and the operating speed is reduced.

[0108] In operation S605 , the vehicle is operated according to a predetermined vehicle operation strategy.

[0109] According to an embodiment of the present disclosure, the maintenance record information of each component includes information such as the number of times each component has been maintained, the time of maintenance, and the estimated usage time after maintenance.

[0110] According to the operation status information and maintenance record information of each component, the fatigue resistance of each component can be generated by comprehensively calculating the usage score of the component through the operation status information and maintenance record information of each component, and determining the fatigue resistance of the component according to the corresponding relationship between the component usage score and the fatigue resistance level of each component. For example, if the operation time of component x is 5 years and the number of maintenance times is 3 times, the corresponding fatigue resistance level is level 2. The fatigue resistance of each component can also be calculated by inputting the operation status information and 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 is less than the fatigue resistance required by each component corresponding to the resistance, it indicates that the component cannot cope with the subsequent environmental fluctuations, which is likely to cause a greater risk of vehicle operation. At this time, it is necessary to send fault warning information to the vehicle-ground integrated electromechanical system and reduce the operating speed so that the target vehicle stops before reaching the target position.

[0112] According to the embodiments of the present disclosure, the fatigue resistance of each component is determined by acquiring the operating status information and maintenance record information of each component, and the current operating plan is evaluated based on the obtained fatigue resistance and the environmental fluctuations faced. If the conditions for safe operation are not met, fault warning information is sent to the vehicle-ground integrated electromechanical system to resolve possible safety hazards and improve the safety of vehicle operation.

[0113] Figure 7 A flowchart of a method for generating a vehicle operation strategy according to a foreign object intrusion situation according to an embodiment of the present disclosure is schematically shown.

[0114] like Figure 7 As shown, the method 700 includes operations S701-S705.

[0115] In operation S701 , in response to receiving foreign object intrusion trajectory information from a target position, a foreign object moving speed and a foreign object moving direction are extracted from the foreign object intrusion trajectory information.

[0116] In operation S702 , the probability of the target vehicle colliding with the foreign object is determined according to the moving direction of the foreign object, the moving speed of the foreign object, and the current running state of the target vehicle.

[0117] In operation S703, it is determined whether the probability is greater than a predetermined probability threshold. When the determination result is yes, operation S704 is performed; when the determination result is no, operation S705 is performed.

[0118] In operation S704, the operating 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 the embodiments of the present disclosure, foreign objects intruding into the track is one of the emergencies that often occur when a vehicle is running. Since foreign objects have a certain speed, if they collide with a running vehicle, it will cause immeasurable losses and damages. Therefore, when facing foreign objects intruding into the track, it is necessary to understand the foreign object intrusion information in advance to generate an effective vehicle operation strategy for this situation.

[0121] The information of foreign objects intruding the track is obtained through the vehicle-ground integrated electromechanical system. The key information of foreign objects intruding the track includes the speed and direction of foreign objects. According to the direction and speed of foreign objects and the current running state of the target vehicle, the probability of collision between the target vehicle and the foreign objects can be determined. If the collision probability is greater than the threshold, it is necessary to adjust the running state of the traction components of the target vehicle, reduce the running speed of the vehicle, change the running route of the vehicle or stop the running of the vehicle.

[0122] For example, at time t, vehicle x is about to run to position z. At this time, the foreign object intrusion track information received at position z is: a bird passes above the track at position z at a moving speed of a. Based on the above information, the probability of the vehicle and the bird colliding is calculated to be 2%, which is greater than the predetermined threshold of 0.01%. At this time, the operating state of the traction component of the target vehicle is adjusted so that the target vehicle reduces its operating speed until the probability is less than the predetermined probability threshold.

[0123] According to the embodiments of the present disclosure, by timely acquiring foreign object intrusion track information from the target position and extracting the foreign object movement speed and foreign object movement direction, the probability of the target vehicle colliding with the foreign object is calculated, the relationship between the probability of the target vehicle colliding with the foreign object and the probability threshold is judged, and the operating state of the vehicle's traction components is adjusted in time to avoid the occurrence of vehicle-foreign object collisions and dangerous accidents, thereby improving the safety of vehicle operation. In addition, due to the early perception of foreign objects in the beyond-visual-range range and the adjustment of strategies, not only the risks existing in the operation of the vehicle are reduced, but also the passengers' perception of abnormal situations is reduced, further improving the passengers' riding experience.

[0124] Based on the above-mentioned vehicle operation strategy generation method based on the vehicle-ground integrated electromechanical system, the present disclosure also provides a vehicle operation strategy generation device based on the vehicle-ground integrated electromechanical system.
