Background Technology

[0002] For rail vehicles, air circuit control is crucial. However, current technologies typically use the air compressor's own controller to control the compressor, and the control logic is relatively simple, such as controlling the compressor based on whether the main air reservoir pressure exceeds limits or whether the compressor overheats. However, with the increasing demand for intelligent air circuit control, relying solely on the air compressor's own controller cannot meet these evolving needs.

[0003] Therefore, how to improve the intelligence of air circuit control for rail vehicles is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0017] When the speed of the maglev train is higher than the power balance speed, the first control unit controls all the air compressors in the preset air circuit to start.

[0018] Optionally, it also includes:

[0019] When any one of the air compressors in the preset air circuit reaches the shutdown pressure condition, the first control unit is used to control all the air compressors in the preset air circuit to stop working.

[0020] When any one of the air compressors in the preset air circuit reaches the start-up pressure condition, the first control unit controls all the air compressors in the preset air circuit to start working.

The second control unit is configured to correspond one-to-one with a rail vehicle car. Each car is equipped with at least one air compressor.

[0030] A rail vehicle pneumatic control system is provided for implementing the above-mentioned rail vehicle pneumatic control method. The rail vehicle pneumatic control system includes:

[0031] The first air passage includes a first air source device, which is set up one-to-one with the odd-numbered carriages of the rail vehicle.

[0032] The second air passage includes a second air source device, which is configured in a one-to-one correspondence with the even-numbered carriages of the rail vehicle; each of the first air source devices and each of the second air source devices includes an air compressor, and each air compressor is equipped with a controller;

For example, by communicating with each air compressor of the rail vehicle to a train-level TCMS and a corresponding vehicle-level TCMS, the train-level TCMS and vehicle-level TCMS can control the air compressors. Additionally, each air compressor is equipped with its own controller. Thus, the air compressor can be controlled by three entities: the first control unit, the second control unit, and the controller. Specifically, when the air compressor is disconnected from both the first control unit and the corresponding second control unit, the air compressor's own controller controls its start and stop; when the air compressor... When the compressor disconnects from the first control unit and communicates normally with the corresponding second control unit, the second control unit is used to control the start and stop of the air compressor.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] The core of this invention is to provide a rail vehicle pneumatic control method, a rail vehicle pneumatic control device, a rail vehicle pneumatic control equipment, and a computer-readable storage medium to improve the intelligence of rail vehicle pneumatic control. Another core aspect of this invention is to provide a rail vehicle pneumatic control system for implementing the above-mentioned rail vehicle pneumatic control method, and a rail vehicle including the rail vehicle pneumatic control system, which can further enhance the intelligence of rail vehicle pneumatic control.

[0054] Please refer to Figure 1 This invention provides a method for controlling the air circuit of a rail vehicle, applied to a rail vehicle air circuit control system. The rail vehicle air circuit control system includes at least one air compressor, a first control unit, and at least one second control unit. Each second control unit is configured to correspond one-to-one with a rail vehicle car. Each car is equipped with at least one air compressor. Each second control unit is communicatively connected to the first control unit, and each air compressor is communicatively connected to the second control unit of its corresponding car. Furthermore, each air compressor is communicatively connected to the first control unit. The first control unit is configured to coordinate the operation of each second control unit, and each second control unit is configured to at least control the operation of the air compressor in its respective car. Each air compressor is equipped with a controller. The rail vehicle air circuit control method includes steps S1 to S3:

[0055] S1: When the air compressor communicates normally with the first control unit, the first control unit is used to control the start and stop of the air compressor;

[0056] S2: When the air compressor disconnects from the first control unit and communicates normally with the corresponding second control unit, the air compressor is started and stopped by the corresponding second control unit.

[0057] S3: When the air compressor is disconnected from both the first control unit and the corresponding second control unit, the controller is used to control the start and stop of the air compressor.

[0058] It should be noted that, in this embodiment of the invention, the first control unit can be the Train Control and Management System (TCMS) of a rail vehicle, and the second control unit can be the control and management system for each car of the rail vehicle. For ease of description and understanding, the first control unit can be referred to as the train-level TCMS, and the second control unit as the vehicle-level TCMS. The train-level TCMS can be installed in the driver's cab of the rail vehicle and is responsible for the coordinated control of the entire vehicle, such as controlling commands involving the entire train, collecting key status information of all vehicles, and implementing advanced strategies, such as equalizing wear of air compressors and energy management. Multiple vehicle-level TCMSs can be installed in each car of the rail vehicle to control the equipment in that car, such as air compressors, doors, air conditioning, lighting, and power supply, collect status information of all sensors and equipment in that car, receive commands from the train-level TCMS, translate them into specific actions and issue them to the equipment in that car, and monitor faults in the equipment in that car.

[0059] Furthermore, it is understood that the second control unit can connect to the first control unit via the train communication network, and the air compressor can also connect to the corresponding second control unit and the first control unit respectively via the train communication network. For example, the train-level TCMS can connect to each car in the trainset via the train bus. For instance, the train-level TCMS can connect to each vehicle-level TCMS via a stranded train bus or Ethernet. The vehicle-level TCMS connects to all intelligent devices in its car via the vehicle bus. Exemplarily, the vehicle bus can be a multi-functional vehicle bus or a CAN (Controller Area Network) bus.

[0060] In other words, this embodiment of the invention achieves control of the air compressors by connecting each air compressor of the rail vehicle to a first control unit and a corresponding second control unit. For example, by connecting each air compressor of the rail vehicle to a train-level TCMS and a corresponding vehicle-level TCMS, control of the air compressors by the train-level TCMS and the vehicle-level TCMS can be achieved. Furthermore, each air compressor is equipped with its own controller. Thus, control of the air compressor can be achieved by three entities: the first control unit, the second control unit, and the controller. Specifically, when the air compressor is disconnected from both the first control unit and the corresponding second control unit, the air compressor is started using its own controller. When the air compressor is disconnected from the first control unit and communicates normally with the corresponding second control unit, the air compressor is started and stopped using the corresponding second control unit. When the air compressor is communicating normally with the first control unit, the air compressor is started and stopped using the first control unit. That is, the embodiments of the present invention can realize multi-level control of the air compressor at the train level, vehicle level and component level. When the air compressor is controlled by the first control unit or the second control unit, the air compressor can be intelligently controlled according to the air supply requirements of the train air circuit, combined with the operating conditions of the entire rail vehicle and the information of the intelligent equipment of each carriage. This is conducive to achieving reliable, green and efficient control and improving the intelligence of the air circuit control of rail vehicles.

[0061] It should be noted that in some embodiments, the communication between the first control unit and the second control unit and the controller equipped on the air compressor itself is serial. That is, the first control unit controls the controller equipped on the air compressor through the second control unit, and ultimately, under the control command of the first control unit, the controller controls the air compressor. In addition, for example, there are two first control units, forming a redundant scheme; in addition, each car is equipped with one second control unit.

[0062] It is understood that the execution order of steps S1, S2 and S3 is not limited in the embodiments of the present invention. When the execution conditions of any one of steps S1, S2 and S3 are met, the corresponding step can be executed.

[0063] It should be noted that, in this embodiment of the invention, under normal circumstances, the air compressor maintains normal communication with the first control unit and the corresponding second control unit. Normal communication between the air compressor and the first control unit, and between the air compressor and the corresponding second control unit, means that information transmission can proceed smoothly between the air compressor and the first control unit, and between the air compressor and the corresponding second control unit. Disconnection between the air compressor and the first control unit, and between the air compressor and the corresponding second control unit, refers to abnormal situations, such as a communication network failure between the air compressor and the first and / or second control units, which prevents information transmission between the air compressor and the first control unit, and between the air compressor and the corresponding second control unit. Therefore, this embodiment of the invention, employing the above-mentioned air circuit control method for rail vehicles, also improves system safety and facilitates reliable control of the air compressor.

[0064] Furthermore, it should be noted that this embodiment does not limit the specific conditions under which the first control unit, the second control unit, and the controller control the start and stop of the air compressor. The focus of this embodiment is to utilize the cooperation of the first control unit, the second control unit, and the controller to achieve multi-level control of the air compressor. In the specific control process, the first control unit, the second control unit, and the controller can control whether to start the air compressor based on whether the air circuit start pressure condition has been reached, respectively. In addition, it is understood that under any control conditions, the control premise of the basic protection function of the air compressor must be met. For example, when the air compressor head temperature, lubricating oil temperature, and cooling air outlet temperature are detected to be too high, the air compressor is controlled to stop for overheat protection; in addition, when the air compressor current is too high, the air compressor is controlled to stop for overload protection, etc. That is, when the air compressor malfunctions, it can take timely action to stop to prevent equipment damage and ensure train safety.

[0065] Additionally, in some embodiments, when the air compressor is communicating normally with the first control unit, the first control unit is used to control the start and stop of the air compressor, including:

[0066] When the rail vehicle is located in an area with external on-board power supply and the rail vehicle's preset air circuit reaches the start-up pressure condition, the first control unit controls all air compressors on the preset air circuit to start.

[0067] It should be noted that, in the embodiments of the present invention, the external on-board power supply area refers to the low-speed section of the corresponding rail vehicle (such as the exit acceleration section and the entry deceleration section), the station, and the preset emergency point, etc. The external on-board power supply area is used to supply power to the rail vehicle's own equipment, including the control system, air conditioning, lighting, air compressor, hydraulic system, etc.

[0068] In other words, when the rail vehicle is located in an area with external on-board power supply and the rail vehicle's preset air circuit reaches the starting pressure condition, all air compressors on the preset air circuit will be started. This can avoid the problem of overheating caused by a single air compressor working continuously. Moreover, it makes full use of the external power supply of the external on-board power supply area to provide stable power, while taking into account the grid power supply capacity, so as to achieve the effect of efficient inflation.

[0069] Additionally, it should be noted that in this embodiment of the invention, the preset air path refers to the air path currently in operation of the rail vehicle, which can be one air path or two air paths (for example, it can be the first air path 11 and the second air path 12 described below).

[0070] In addition, in some embodiments, the rail vehicle is a maglev train. When the cruising speed of the maglev train is greater than or equal to a preset value, and the air compressor is communicating normally with the first control unit, the first control unit is used to control the start and stop of the air compressor, including:

[0071] When the rail vehicle leaves the external on-board power supply area and the rail vehicle speed is lower than the power balance speed, the first control unit controls the air compressor to remain in a stopped state.

[0072] In other words, the rail vehicle in this embodiment is a high-speed maglev train, such as a conventional high-speed maglev train or a superconducting high-speed maglev train. In this embodiment, the cruising speed of the maglev train is greater than a preset value, meaning that when the speed of the maglev train is high enough, the maglev train runs on a high-speed mainline without an external onboard power supply area. The maglev train's levitation does not require any onboard power to maintain. The onboard power required by the train (for air conditioning, lighting, etc.) can be obtained by generating electricity through a linear generator on the levitation electromagnet. That is to say, the cruising speed in this embodiment refers to the speed of the maglev train during normal operation, representing the "high speed" in the concept of "high-speed maglev train". In addition, this embodiment does not limit the specific value of the preset value. Those skilled in the art can refer to the definition of high speed in industry standards. For example, the preset value can be 500 km / h.

[0073] Additionally, it should be noted that the power balance speed in this embodiment refers to the speed at which the power generated by the linear generator on the levitation electromagnet matches the total resistance power consumed by the maglev train to overcome various resistances. Here, matching means that the power generated by the linear generator on the levitation electromagnet is equal to or higher than the total resistance power within a preset range.

[0074] In other words, when the maglev train leaves the external onboard power supply area and its speed has not yet reached the power balance speed, the first control unit controls the air compressor to remain in a stopped state to avoid the air compressor starting, consuming electrical energy, affecting the acceleration of the maglev train, and reducing energy consumption. This scheme is conducive to achieving energy saving of the whole vehicle and meeting the green energy-saving requirements for the air circuit control of the maglev train.

[0075] In addition, in some embodiments, when the air compressor is communicating normally with the first control unit, controlling the start and stop of the air compressor using the first control unit further includes:

[0076] When the speed of the maglev train is higher than the power balance speed, the first control unit controls all the air compressors in the preset air circuit to start.

[0077] In other words, when the speed of the maglev train is higher than the power balance speed, all the air compressors in the preset air circuit are started to consume the energy of the maglev train beyond the power balance speed. This helps to make full use of the excess electrical energy of the maglev train and achieve energy-saving and efficient operation of the maglev train.

[0078] Additionally, in some embodiments, it also includes:

[0079] When any air compressor in the preset air circuit reaches the shutdown pressure condition, the first control unit controls all air compressors in the preset air circuit to stop working.

[0080] When any air compressor in the preset air circuit reaches the starting pressure condition, the first control unit controls all air compressors in the preset air circuit to start working.

[0081] In other words, if the pressure of any air compressor in the preset air circuit reaches the shutdown pressure condition, all air compressors in that preset air circuit will be controlled to stop working, so as to prevent the system pressure from continuing to rise due to inertia and exceeding the safety limit, thus ensuring the safety of the rail vehicle; when any air compressor in the preset air circuit reaches the start-up pressure condition, all air compressors in the preset air circuit will be controlled to start working, thus preventing the problem of overheating caused by a single air compressor working continuously.

[0082] Please refer to Figure 2In addition to the above-mentioned air circuit control method for rail vehicles, this embodiment of the invention also provides an air circuit control system for rail vehicles. This air circuit control system is used to implement the air circuit control method for rail vehicles disclosed in any of the above embodiments. The air circuit control system includes a first air circuit 11, a second air circuit 12, a first control unit, and at least one second control unit. The first air circuit 11 includes a first air source device 111, which is configured to correspond one-to-one with the odd-numbered cars of the rail vehicle. The second air circuit 12 includes a second air source device 121, which is configured to correspond one-to-one with the even-numbered cars of the rail vehicle. Each first air source device 111 and each second air source device 121 includes an air compressor, and each air compressor is equipped with a controller. The first control unit is communicatively connected to each second control unit and each air compressor. The first control unit is configured to coordinate the work of each second control unit. Each second control unit is configured to correspond one-to-one with the cars of the rail vehicle and is configured to control at least the air compressor of its car. Each air compressor is communicatively connected to the second control unit of its corresponding car.

[0083] It is understood that this rail vehicle air circuit control system is used to implement the rail vehicle air circuit control method disclosed in any of the above embodiments. That is, this embodiment utilizes the first control unit, the second control unit, and the controller to achieve multi-level control of the air compressor at the train level, vehicle level, and component level. This is beneficial for intelligent air circuit control based on the rail vehicle's air circuit demand and the rail vehicle's operating conditions, thus contributing to reliable, environmentally friendly, and efficient rail vehicle air circuit control. This rail vehicle air circuit control system possesses at least the beneficial effects of the aforementioned rail vehicle air circuit control method, which will not be elaborated further here.

[0084] Furthermore, it is understood that the rail vehicle air circuit control system includes a first air circuit 11 and a second air circuit 12, meaning that the entire train is equipped with two air circuits, which is a redundant configuration to improve system reliability. Additionally, in some embodiments, both the first air circuit 11 and the second air circuit 12 are connected to a reversing valve 13.

The first control unit is configured to coordinate the operation of each second control unit, and the second control unit is configured to at least control the operation of the air compressor in its respective car. Each air compressor is equipped with a controller.
