Abstract
Description
Technical Field
[0001] This application relates to the field of electric locomotive configuration, and more particularly to a configuration system and method for a distributed power electric locomotive. Background Technology
[0002] Distributed power locomotives and their supporting systems are used in urban subway tunnel shield construction to transport excavated soil out of the tunnel and mortar, tunnel segments, and other materials into the tunnel. They are widely used in the construction of long tunnels with steep gradients. The entire locomotive relies on lithium batteries to provide DC power to the whole vehicle, and uses frequency converters to drive the motors to provide traction and electric braking force, thus achieving traction and braking for the entire locomotive formation.
[0003] In tunnel construction with varying slopes, the required traction capacity of electric locomotives differs, leading to variations in the number of powered dump trucks configured with distributed power electric locomotives. When equipment operating conditions change, technicians must design control programs specifically for different types of powered dump trucks, reducing the equipment's versatility. Furthermore, during locomotive use, if electrical components or drive mechanisms of the powered dump trucks malfunction, preventing normal vehicle operation, and if the fault cannot be quickly resolved, rapid emergency handling is necessary to ensure the smooth progress of construction operations before transferring the disabled vehicle to a maintenance area for repair.

[0060] The weight of the dump truck includes the weight of the powered dump truck and the weight of the non-powered dump truck.
[0061] It should be noted that, Figure 1 This is merely an illustration of a configuration system for a distributed power electric locomotive in this embodiment, and does not limit the structure of the configuration system for a distributed power electric locomotive of the present invention.
[0062] In this embodiment of the disclosure, the vehicle data includes: the unloaded weight m1 of the whole vehicle (including the locomotive, mortar truck, powered dump truck, non-powered dump truck, and segment truck), the weight m2 of a fixed number of segments and mortar, the transmission ratio i1 of the locomotive locomotive, the transmission ratio i2 of the powered dump truck, the rated torque F1 of the locomotive locomotive drive mechanism, and the rated torque F2 of the powered dump truck drive mechanism.

[0064] The tilt sensor 2-1 is installed at the locomotive head and is used to measure the real-time tilt angle value of the distributed power locomotive.
[0065] The weighing sensor 2-2 of the dump truck is installed on each powered and unpowered dump truck to measure the weight of the dump truck transported by each truck.
[0066] The central control module 4 is also used to convert the real-time tilt angle value of the distributed power electric locomotive into the actual slope value of the distributed power electric locomotive, and to determine the total weight of the distributed power electric locomotive based on the weight of the slag transported by each slag truck, the empty weight of the whole vehicle, and the weight of a fixed number of segments and mortar.
[0067] It should be noted that the central control module 4 is pre-set with a data processing unit function block, an actual continuous theoretical traction force calculation unit function block, and a group configuration and drive mechanism quantity calculation unit function block;
[0068] The data processing unit function block is called to convert the real-time tilt angle value θ of the distributed power locomotive into the actual slope value β of the distributed power locomotive; where β = tanθ; the weight m3 of the transported slag from the dump truck is calculated and converted into the total weight m of the distributed power locomotive, where m = m1 + m2 + m3.
[0069] The central control module 4 is also used to determine the maximum continuous theoretical traction force required by the distributed power electric locomotive based on the total weight of the distributed power electric locomotive and the actual gradient value of the distributed power electric locomotive.
[0070] It should be noted that after the data processing unit function block completes the data processing, the central control module 4 will call the actual continuous theoretical traction force calculation unit function block to calculate the actual continuous theoretical traction force required by the vehicle, and will then display the calculated actual continuous theoretical traction force value F. j Where, F0=mgω, F i =mgβ,F j =F i +F0, where ω is the locomotive's continuous resistance coefficient; g is the local gravitational acceleration, taken as g = 9.8 m / s². 2 ;F i F0 represents the real-time gradient and slope resistance of the distributed power locomotive, in kN; F0 represents the real-time basic resistance of the distributed power locomotive, in kN; F j This represents the maximum continuous theoretical traction force required for the entire vehicle of a distributed power electric locomotive, expressed in kN.
[0071] In this embodiment of the disclosure, the central control module 4 is also used to store the vehicle data, the total weight of the distributed power electric locomotive, the real-time tilt angle value of the distributed power electric locomotive, and the maximum continuous theoretical traction force required by the distributed power electric locomotive.
[0072] In this embodiment of the disclosure, the central control module 4 is further configured to determine, based on the locomotive head transmission ratio, the power dump truck transmission ratio, the rated torque of the locomotive head drive mechanism, and the rated torque of the power dump truck drive mechanism, the minimum value of the number of power dump truck drive mechanisms required when the continuous maximum theoretical traction force required by the entire power distributed locomotive is greater than or equal to that required by the whole vehicle, and to use the minimum value as the number of power dump truck drive mechanisms to be put into operation.
[0073] The central control module 4 is also used to determine the number of power dump trucks to be deployed based on the number of drive mechanisms required for the power dump trucks.
[0074] It should be noted that after the actual continuous theoretical traction force calculation unit function block completes its calculation, the central control module 4 will call the group configuration and drive mechanism quantity calculation unit function block. Based on the locomotive head transmission ratio i1, the power dump truck transmission ratio i2, the locomotive head drive mechanism rated torque F1, and the power dump truck drive mechanism rated torque F2, the module will perform calculation data processing and comparison to determine the required number of power dump trucks in the entire vehicle formation and the number of drive motors required for each power dump truck. The specific processing and comparison method of the group configuration and drive mechanism quantity calculation unit function block is as follows:
[0075] The main configuration of a distributed power electric locomotive includes: 1 locomotive head, 3 powered dump trucks, 2 unpowered dump trucks, 1 mortar truck, and several segment trucks. Each powered dump truck has 3 sections, each with 2 drive mechanisms, for a maximum of 6 drives.
[0076] (1) Assign n the values 1, 2, 3, 4, 5, 6 in sequence, and calculate according to the following formula, where (n value is not greater than 6).
[0077] F s =F1*i1*2+F2*i2*n
[0078] n—The actual number of drive mechanisms used in the power dump truck;
[0079] F s —The number of train sets deployed and the maximum traction force that the drive mechanism can provide.
[0080] (2) Calculate F using this assigned value s With F j Compare, if F s ≥F j Then, n is taken as the actual number of power dump truck drive mechanisms that need to be put into use for the whole vehicle and stored in the internal data register of the central control module 4.
[0081] (3) After the group configuration and drive mechanism quantity calculation unit function block calculates the value of n, the actual number of powered dump trucks in the entire vehicle group, m, will be calculated according to the following formula. If n is even, the actual number of powered dump trucks m = n / 2; if n is odd, the actual number of powered dump trucks m = n / 2. The value of m is stored in the internal data register of the central control module 4, i.e., m = n / 2, where n is an even number; n is an odd number, and m is the actual number of powered dump trucks.
[0082] In the embodiments disclosed herein, such as Figure 3As shown, the configuration system also includes: a drive mechanism control module 5 and a power control module 6;
[0083] The drive mechanism control module 5 is used to control the operation of the drive mechanism of the required power dump truck.
[0084] It should be noted that the drive mechanism control module 5 can also issue an alarm.
[0085] The power control module 6 is used to control the operation of the power dump trucks that need to be put into operation.
[0086] Furthermore, such as Figure 3 As shown, the configuration system also includes: a communication detection module 7 and a fault detection module 8;
[0087] The communication detection module 7 is used to monitor the communication status of the power control module and send the communication status to the central control module 4.
[0088] The fault detection module 8 is used to monitor the fault status of the drive mechanism control module and send the fault status to the central control module 4.
[0089] Furthermore, the central control module 4 is also used to store the number of drive mechanisms for the required power dump trucks and the number of power dump trucks required.
[0090] The central control module 4 is also used to send the number of drive mechanisms of the required power dump trucks and the number of power dump trucks to be deployed to the operation and display module 1 via Profinet communication.
[0091] It should be noted that the driver in the driver's cab can select the power dump truck and drive mechanism that need to work based on the number n of the power dump truck drive mechanism control modules 5 and the number m of the power dump trucks displayed on the operation and display module 1. Then, the central control module 4 controls the drive mechanism control module 5 and the power control module 6 that need to work based on the selected power dump truck and drive mechanism.
[0092] The central control module 4 is also used to store the communication status and the fault status, and send the communication status and the fault status to the operation and display module 1;
[0093] The operation and display module 1 is also used to display the communication status and the fault status.
[0094] The operation and display module 1 is also used to send an instruction to the central control module 4 to cancel the operation of the power dump truck drive mechanism when the drive mechanism of the power dump truck malfunctions.
[0095] The central control module 4 is also used to send the instruction for the operation of the power dump truck drive mechanism to cancel the fault to the drive mechanism control module 5.
[0096] The drive mechanism control module 5 is also used to receive the instruction and then control the corresponding drive mechanism of the power dump truck to stop working.
[0097] Specifically, after the driver selects a specific powered dump truck in the operation and display module 1, the communication detection module 7 will perform communication checks on the power control modules 6 of all selected powered dump trucks. If the communication online status of a power control module 6 of a particular powered dump truck is normal, then that power control module 6 is considered online (i.e., the powered dump truck is online); if it is abnormal, then that power control module 6 is considered offline (i.e., the powered dump truck is offline). The vehicle can only start normally when all the power control modules 6 of the selected powered dump trucks are online; if any of the selected powered dump trucks' power control modules 6 are offline, the vehicle cannot start. The communication detection module 7 does not check the power control modules 6 of unselected powered dump trucks; unselected powered dump trucks cannot operate as powered dump trucks and can only be towed as unpowered dump trucks.
[0098] For the selected power dump truck in the operation and display module 1, the fault detection module 8 will perform fault detection on all selected drive mechanism control modules 5 of that power dump truck. If the fault alarm status of a certain drive mechanism control module 5 is normal, the drive mechanism is considered to be normal; if it is abnormal, the drive mechanism control module 5 is considered to be faulty, and the vehicle cannot run. If a fault alarm occurs in the drive mechanism control module 5 due to a fault in a certain drive mechanism, causing the vehicle to be unable to run, and if the fault cannot be quickly resolved and affects the construction operation, the drive mechanism with the fault alarm can be deselected in the operation and display module 1, so that the fault detection module 8 will no longer perform fault detection on that drive mechanism control module 5, and the existing alarm will be reset in the operation and display module 1, realizing emergency operation of the vehicle.
[0099] In this embodiment, the central control module 4 is connected to the power control module 6, the drive mechanism control module 5, and the operation and display module 1 via a star topology network.
[0100] The configuration system of this embodiment has the following advantages:
[0101] 1. By freely configuring the power dump trucks, the same train of distributed power locomotives can quickly change the vehicle formation, and the same locomotive control program can meet the usage requirements of different numbers of power dump trucks in on-site construction.
[0102] 2. Through the free configuration of the power dump truck and the custom configuration method of the drive mechanism, the required number of power dump trucks and drive mechanisms can be automatically calculated at different construction sites, saving costs and energy consumption for the construction site.
[0103] 3. When a failure occurs in a certain drive mechanism of the vehicle and cannot be quickly resolved, the faulty mechanism can be temporarily shielded from the control perspective, enabling the vehicle to operate temporarily, reducing the impact on on-site construction operations, and improving the effective utilization rate of the vehicle.
[0104] 4. It enables distributed power locomotives to meet different operating conditions without changing the control program, saving program development and modification costs and improving the versatility of locomotives.
[0105] In summary, the configuration system for distributed power locomotives proposed in this embodiment can quickly and accurately calculate the number of power dump trucks and the number of drive mechanisms required for the current construction environment, and can also flexibly group them based on the required number.
[0106] Based on the above-described configuration system for distributed power electric locomotives, the present invention also provides a configuration method for distributed power electric locomotives, the process of which is as follows: Figure 4 As shown, the method includes:

[0109] Step 3: Configure the distributed power locomotives according to the number of powered dump trucks and the number of drive mechanisms of the powered dump trucks;
[0110] The distributed power locomotive includes: locomotive head, powered dump truck, unpowered dump truck, mortar truck, and segment truck;
[0111] The weight of the dump truck includes the weight of the powered dump truck and the weight of the non-powered dump truck.
[0112] In this embodiment of the disclosure, the vehicle data includes: the unloaded weight m1 of the whole vehicle (including the locomotive, mortar truck, powered dump truck, non-powered dump truck, and segment truck), the weight m2 of a fixed number of segments and mortar, the transmission ratio i1 of the locomotive locomotive, the transmission ratio i2 of the powered dump truck, the rated torque F1 of the locomotive locomotive drive mechanism, and the rated torque F2 of the powered dump truck drive mechanism.
[0113] The sensors include: tilt sensor and dump truck weighing sensor;
[0114] The tilt sensor is installed at the locomotive head to measure the real-time tilt angle value of the distributed power locomotive;
[0115] The weighing sensors of the dump trucks are installed on each powered and unpowered dump truck to measure the weight of the dump truck transported by each truck.
[0116] The central control module is used to convert the real-time tilt angle value of the distributed power locomotive into the actual slope value of the distributed power locomotive, and the weight of the distributed power locomotive is determined based on the weight of the slag transported by each slag truck, the empty weight of the whole vehicle, and the weight of a fixed number of segments and mortar.
[0117] It should be noted that the central control module is pre-set with a data processing unit function block, an actual continuous theoretical traction force calculation unit function block, and a group configuration and drive mechanism quantity calculation unit function block;
[0118] The data processing unit function block is called to convert the real-time tilt angle value θ of the distributed power locomotive into the actual slope value β of the distributed power locomotive; where β = tanθ; the weight m3 of the transported slag from the dump truck is calculated and converted into the total weight m of the distributed power locomotive, where m = m1 + m2 + m3.
[0119] The central control module determines the maximum theoretical continuous traction force required by the distributed power electric locomotive based on the total weight of the locomotive and the actual gradient of the locomotive.
[0120] It should be noted that after the data processing unit function block completes the data processing, the central control module will call the actual continuous theoretical traction force calculation unit function block to calculate the actual continuous theoretical traction force required by the vehicle, and will then display the calculated actual continuous theoretical traction force value F. j Where, F0=mgω, F i =ngβ、F j =F i +F0, where ω is the locomotive's continuous resistance coefficient; g is the local gravitational acceleration, taken as g = 9.8 m / s². 2 ;F i F0 represents the real-time gradient and slope resistance of the distributed power locomotive, in kN; F0 represents the real-time basic resistance of the distributed power locomotive, in kN; F j This represents the maximum continuous theoretical traction force required for the entire vehicle of a distributed power electric locomotive, expressed in kN.
[0121] In this embodiment of the disclosure, the vehicle data, the total weight of the distributed power electric locomotive, the real-time tilt angle value of the distributed power electric locomotive, and the maximum continuous theoretical traction force required by the distributed power electric locomotive are stored in the central control module.
[0122] In this embodiment of the disclosure, the central control module determines the minimum number of power dump truck drive mechanisms required when the continuous maximum theoretical traction force required by the entire vehicle is greater than or equal to that required by the distributed power electric locomotive, based on the transmission ratio of the locomotive head, the transmission ratio of the power dump truck, the rated torque of the locomotive head drive mechanism, and the rated torque of the power dump truck drive mechanism. The minimum value is then used as the number of power dump truck drive mechanisms to be deployed.
[0123] The required number of powered dump trucks is determined based on the number of drive mechanisms required for the powered dump trucks.
[0124] It should be noted that after the actual continuous theoretical traction force calculation unit function block completes its calculation, the central control module will call the group configuration and drive mechanism quantity calculation unit function block. Based on the locomotive head transmission ratio i1, the power dump truck transmission ratio i2, the locomotive head drive mechanism rated torque F1, and the power dump truck drive mechanism rated torque F2, the module will compare and process the calculated data to determine the required number of power dump trucks in the entire vehicle formation and the number of drive motors required for each power dump truck. The specific processing and comparison method of the group configuration and drive mechanism quantity calculation unit function block is as follows:
[0125] The main configuration of a distributed power electric locomotive includes: 1 locomotive head, 3 powered dump trucks, 2 unpowered dump trucks, 1 mortar truck, and several segment trucks. Each powered dump truck has 3 sections, each with 2 drive mechanisms, for a maximum of 6 drives.
[0126] (1) Assign n the values 1, 2, 3, 4, 5, 6 in sequence, and calculate according to the following formula, where (n value is not greater than 6).

[0129] F s —The number of train sets deployed and the maximum traction force that the drive mechanism can provide.
[0130] (2) Calculate F using this assigned value s With F j Compare, if F s ≥F jThen, n is taken as the actual number of power dump truck drive mechanisms that need to be put into use for the whole vehicle and stored in the internal data register of the central control module 4.
[0131] (3) After the group configuration and drive mechanism quantity calculation unit function block calculates the value of n, the actual number of powered dump trucks in the entire vehicle group, m, will be calculated according to the following formula. If n is even, the actual number of powered dump trucks m = n / 2; if n is odd, the actual number of powered dump trucks m = n / 2. The value of m is stored in the internal data register of the central control module 4, i.e., m = n / 2, where n is an even number; n is an odd number, and m is the actual number of powered dump trucks.
[0132] In this embodiment of the disclosure, the drive mechanism control module is used to control the operation of the drive mechanism of the power dump truck to be put into operation.
[0133] The power control module is used to control the operation of the required powered dump trucks.
[0134] The communication detection module is further used to monitor the communication status of the power control module, and the communication status is sent to the central control module.
[0135] The fault detection module monitors the fault status of the drive mechanism control module and sends the fault status to the central control module.
[0136] Furthermore, the required number of drive mechanisms for the power dump trucks and the required number of power dump trucks are stored in the central control module.
[0137] The required number of drive mechanisms for the power dump trucks and the required number of power dump trucks are sent to the operation and display module via Profinet communication.
[0138] It should be noted that the driver in the cab can select the power dump truck and drive mechanism that need to work based on the number of power dump truck drive mechanism control modules n and the number of power dump trucks m displayed on the operation and display module. Then, the central control module controls the drive mechanism control module and power control module that need to work based on the selected power dump truck and drive mechanism.
[0139] The communication status and the fault status are transmitted to the operation and display module, and the communication status and the fault status are displayed.
[0140] When the drive mechanism of the power dump truck malfunctions, the operation and display module sends an instruction to the central control module to cancel the operation of the power dump truck drive mechanism.
[0141] The central control module sends the instruction for the operation of the power dump truck drive mechanism to the drive mechanism control module to cancel the fault.
[0142] The drive mechanism control module controls the corresponding drive mechanism of the power dump truck to stop working.
[0143] Specifically, after the driver selects a specific powered dump truck in the operation and display module, the communication detection module will perform communication checks on the power control modules of all selected powered dump trucks. If the communication online status of a power control module of a particular powered dump truck is normal, then the power control module is considered online (i.e., the powered dump truck is online); if it is abnormal, then the power control module is considered offline (i.e., the powered dump truck is offline). The vehicle can only start normally when the power control modules of all selected powered dump trucks are online; if any selected powered dump truck's power control module is offline, the vehicle cannot start. The communication detection module does not check the power control modules of unselected powered dump trucks; unselected powered dump trucks cannot operate as powered dump trucks and can only be towed as unpowered dump trucks.
[0144] For the selected power dump truck in the operation and display module, the fault detection module will perform fault detection on all selected drive mechanism control modules of that power dump truck. If the fault alarm status of a drive mechanism control module is normal, the drive mechanism is considered normal; if it is abnormal, the drive mechanism control module is considered to be faulty, and the vehicle cannot operate. If a drive mechanism control module fault alarm occurs due to a fault in a drive mechanism during vehicle operation, causing the vehicle to be unable to operate, and if the fault cannot be quickly resolved and affects construction work, the drive mechanism with the fault alarm can be deselected in the operation and display module. This will prevent the fault detection module from performing fault detection on that drive mechanism control module, and the existing alarm will be reset in the operation and display module, enabling emergency operation of the vehicle.
[0145] In summary, the configuration method for distributed power locomotives proposed in this embodiment can quickly and accurately calculate the number of power dump trucks and the number of drive mechanisms required for the power dump trucks in the current construction environment, and can also flexibly group them based on the required number.
