[0025] In order to make the technical problems, technical solutions, and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0027] Next, refer to Figure 1-8 to describe in detail the method and system for replacing the battery of a rail vehicle according to an embodiment of the present invention.

[0028] In some embodiments, as Figure 1 shown, the method for replacing the battery of a rail vehicle includes the following steps:

[0029] S101, obtain the remaining total power of the rail vehicle battery pack.

[0030] In some embodiments, a rail vehicle is powered by a battery pack. A rail vehicle has multiple batteries for power supply, and the multiple batteries are placed in different battery compartments respectively. When one battery runs out of power, another battery can be used for power supply. Theoretically, as long as the number of batteries is sufficient, the rail vehicle can keep running. Therefore, it is necessary to obtain the remaining total power of all the batteries in the rail vehicle.

[0031] In some embodiments, as Figure 2 shown, step S101, obtaining the remaining total power of the rail vehicle battery pack, further includes the following steps:

[0032] S201, obtain the remaining power of each battery in the rail vehicle battery pack.

[0033] In some embodiments, since a rail vehicle is powered by multiple batteries, when one battery runs out of power, another battery can be used for power supply. Therefore, in the battery pack of the rail vehicle, some batteries have sufficient power, while some batteries have low power or are exhausted, and it is necessary to obtain the remaining power of each battery separately.

[0034] S202, obtain the remaining total power of the rail vehicle battery pack according to the remaining power of each battery.

[0035] In some embodiments, after obtaining the remaining power of each battery, adding up the remaining power of each battery can obtain the remaining total power of the rail vehicle battery pack.

[0036] The rail vehicle is powered by a battery pack, which can ensure that the battery has sufficient power. When the power of a single battery is insufficient, it can be simply switched to be powered by another battery without having to reach a platform to recharge or replace the battery, thus ensuring the power issue during operation.

[0037] S102. Determine the driving mileage of the rail vehicle according to the remaining total power.

[0038] In some embodiments, after obtaining the remaining total power of the rail vehicle, the driving mileage of the rail vehicle can be calculated based on the remaining total power of the rail vehicle.

[0039] In some embodiments, as Figure 3 shown, step S102, determining the driving mileage of the rail vehicle according to the remaining total power, further includes:

[0040] S301. Obtain the first mapping relationship between the driving distance and the battery power of the rail vehicle in the current operating section according to the historical database.

[0041] In some embodiments, the driving distance of the rail vehicle can be mapped to the battery power of the rail vehicle. Here, the mapping relationship is the value of the battery power consumed by the rail vehicle for every certain distance traveled.

[0042] In some embodiments, the first mapping relationship between the driving distance and the battery power of the rail vehicle can be established through the historical database. Through the historical operation data, the first mapping relationship between the driving distance and the battery power of the rail vehicle in the historical data between the location of the rail vehicle and the next platform is obtained. Since it is the same section of the road, a relatively accurate data can be obtained for the distance that the remaining total power of the current rail vehicle can travel.

[0043] S302. Determine the driving mileage of the rail vehicle according to the remaining total power and the first mapping relationship.

[0044] In some embodiments, after obtaining the first mapping relationship between the driving distance and the battery power of the rail vehicle, the mileage that the remaining total power of the rail vehicle can travel can be easily obtained by comparing the previously obtained remaining total power of the rail vehicle with the first mapping relationship.

[0045] In some embodiments, as Figure 4 shown, step S102, determining the driving mileage of the rail vehicle according to the remaining total power, further includes:

[0046] S401. Obtain the second mapping relationship between the driving distance and the battery power of the rail vehicle in the previous operating section of the current line of the rail vehicle.

[0047] In some embodiments, due to external factors such as rain and snow weather, in actual operation, if the mapping relationship of the current running section in the historical database is adopted, the influence of external factors such as the current weather may be ignored. Therefore, it is necessary to obtain the second mapping relationship between the driving distance of the rail vehicle and the battery power in the previous running section of the current line. Since the environments of the current running section and the previous running section are similar, the influence of external factors can be ignored.

[0048] In other embodiments, as the battery is continuously used, its discharge capacity will decrease. For example, the dischargeable proportion of a newly bought battery is 95%, and the discharge proportion gradually decreases as it is continuously used. Or rather, as the rail vehicle ages, its power consumption also increases. Therefore, it is necessary to refer to the mapping relationship between the battery power and the driving distance within the most recent preset time period, so as to obtain a more accurate required power. For example, taking the current moment as the end point, a certain preset time is pushed forward, and the mapping relationship is established based on the battery power and the driving distance during this period. Since this period is the time period closest to the current moment, the problem of battery charge and discharge efficiency can be almost ignored, and thus more accurate data on the running distance that the remaining total battery power can support can also be obtained through this mapping relationship.

[0049] S402. Determine the driving mileage of the rail vehicle according to the remaining total power and the second mapping relationship.

[0050] In some embodiments, after obtaining the second mapping relationship between the driving distance of the rail vehicle and the battery power, the mileage that the remaining total power of the rail vehicle can run can be easily obtained by referring to the second mapping relationship based on the previously obtained remaining total power of the rail vehicle.

[0051] S103. Obtain the track length for the rail vehicle to run to the next platform.

[0052] In some embodiments, after obtaining the driving mileage corresponding to the remaining total power of the rail vehicle, it is also necessary to obtain the track length from the current position of the rail vehicle to the next platform.

[0053] In some embodiments, as Figure 5 shown, step S103, obtaining the track length for the rail vehicle to run to the next platform, further includes:

[0054] S501. Obtain the first position where the rail vehicle is located and the second position where the next platform is located.

[0055] In some embodiments, to obtain the track length between the rail vehicle and the next platform, it is necessary to obtain the first position where the rail vehicle is located and the second position where the next platform is located. The position of the platform is fixed, so it is relatively simple to obtain the second position of the next platform.

[0056] In addition to the second position of the next platform, it is also necessary to obtain the first position where the rail vehicle is located. Generally speaking, the battery of the rail vehicle is replaced on the platform. Therefore, under normal circumstances, the second position where the rail vehicle is located can be obtained through the platform position where the rail vehicle is located.

[0057] Under normal circumstances, the rail vehicle calculates the power required to run to the next platform on the platform before running, and there will be no situation of insufficient battery power during the running process.

[0058] In some special cases, during the running process of the rail vehicle, due to reasons such as battery failure, the battery power may be insufficient, and it is necessary to replace the battery to ensure the normal operation of the rail vehicle. Since the battery pack power supply scheme is adopted, a battery replacement device can be installed on the rail vehicle to replace the unused and low-power batteries or the faulty batteries. When such a special situation occurs, since the rail vehicle is running on the track, its position information cannot be directly replaced by the position information of the platform as in the normal situation. Therefore, it is necessary to use a positioning device to position the rail vehicle by methods such as GPS (Global Positioning System) positioning and UWB (Ultra Wide Band) positioning to obtain the first position where the rail vehicle is located.

[0059] S502. Determine the track length according to the first position and the second position.

[0060] In some embodiments, the track length of the rail vehicle running from the first position to the second position is obtained through the first position where the rail vehicle is located and the second position where the next platform is located.

[0061] In some embodiments, as Figure 6 shown, step S502, determining the track length according to the first position and the second position, can also be implemented through the following steps:

[0062] S601. Obtain at least two route arrangements between the first position and the second position according to the first position and the second position;

[0063] S602. Screen out the route arrangement with the shortest track length from at least two route arrangements;

[0064] S603. Determine the track length of the route arrangement through the electronic map.

[0065] In some embodiments, since the rail vehicle can select more than one available route without affecting the operation of other rail vehicles when traveling from one location to another, among multiple available routes, the rail vehicle preferentially selects the route with the shortest track length as its traveling route, so that in the event of a rail vehicle failure, the rail vehicle can reach the platform for maintenance as soon as possible.

[0066] S104. Compare the driving mileage and the track length. If the driving mileage is less than the track length, issue a battery replacement instruction to replace the batteries in the rail vehicle's battery pack in ascending order of the power of each single battery until the driving mileage that can be run with the remaining total power is greater than or equal to the track length.

[0067] In some embodiments, obtain the driving mileage corresponding to the remaining total power of the rail vehicle and compare the driving mileage with the track length. When the driving mileage corresponding to the remaining total power of the rail vehicle is greater than or equal to the track length, it indicates that the remaining total power of the rail vehicle is sufficient to support the rail vehicle to travel to the next platform. Therefore, there is no need to replace the battery.

[0068] In some embodiments, theoretically speaking, if the driving mileage corresponding to the remaining total power of the rail vehicle is exactly equal to the track length, there is no need to replace the battery. However, in most cases, to prevent errors, from a safety perspective, it is actually best to replace the low-power battery at this time.

[0069] In some embodiments, when the driving mileage corresponding to the remaining total power of the rail vehicle is less than the track length, it indicates that the remaining total power of the rail vehicle cannot meet the requirement for the rail vehicle to run to the next platform. Therefore, it is necessary to replace the low-power batteries in the rail vehicle's battery pack so that the battery power of the rail vehicle can meet the requirement for running from the current position of the rail vehicle to the next platform.

[0070] Among them, the rail vehicle is powered by a battery pack. When the power of one battery is used up or lower than a preset threshold, it can be switched to the next battery for power supply. Each battery is placed in a different battery compartment. Therefore, when the rail vehicle needs to replace a low-power battery, it can be directly replaced from the corresponding battery compartment. It should be noted that the preset threshold generally refers to a threshold at which the battery power is too low to maintain the normal operation of the rail vehicle but has not been exhausted.

[0071] In some embodiments, when the rail vehicle detects that the power of one battery in the battery pack is used up or lower than a preset threshold, it issues a battery replacement instruction and uses a fully charged battery to replace the battery to ensure the power state of the rail vehicle's battery pack.

[0072] In some other embodiments, in the above embodiments, the total remaining power of the rail vehicle is obtained, the driving mileage that the rail vehicle can travel is obtained from the total remaining power of the rail vehicle, and the driving mileage is compared with the track length of the rail vehicle to the next platform. From this, another implementation method can be conceived, that is, obtaining the track length of the rail vehicle to the next platform, and through this track length, calculating the battery power required for the rail vehicle to run through this track length, and comparing this battery power with the total remaining power of the rail vehicle.

[0073] When the battery power is greater than the total remaining power of the rail vehicle, it means that the rail vehicle cannot complete the operation of the corresponding track length and needs to replace the battery; when the battery power is less than or equal to the total remaining power of the rail vehicle, it means that the total remaining power of the rail vehicle is sufficient to support the completion of the operation of the corresponding track length, so there is no need to replace the battery.

[0074] In some embodiments, when, according to the rail vehicle battery replacement method of the above embodiments, all the batteries with low power in the rail vehicle battery pack are replaced with fully charged batteries, but the detection result still cannot meet the driving mileage requirement to run to the next platform, an alarm will be issued. At this time, maintenance personnel need to carry out maintenance to check whether it is a battery problem or a failure of the train power system or other systems.

[0075] Through the rail vehicle battery replacement method of the above embodiments, there is no need for the rail vehicle to stay at the platform for charging. Only the batteries with insufficient power on the rail vehicle need to be replaced, and the replaced batteries can be placed on the platform for charging when the rail vehicle arrives at the station, which greatly improves the operation efficiency of the rail vehicle. And when a fault occurs in the rail vehicle battery, other batteries can be switched for power supply, and after switching to other batteries for power supply, the faulty battery can be replaced to ensure the operation safety of the rail vehicle.

[0076] As Figure 7 shown, the present invention also provides a rail vehicle battery replacement system 100. The rail vehicle battery replacement system 100 includes: an on-vehicle controller 10, a battery replacement device 20, wherein,

[0077] The on-vehicle controller 10 obtains the total remaining power of the rail vehicle battery pack; determines the driving mileage of the rail vehicle according to the total remaining power; obtains the track length between the rail vehicle and the next platform; compares the driving mileage and the track length; if the driving distance is less than the track length, a battery replacement instruction is issued to sequentially replace the batteries in the rail vehicle battery pack from low to high according to the single battery power until the driving mileage that can be run with the total remaining power meets the track length;

[0078] The battery replacement device 20 is used to replace the battery according to the battery replacement instruction.

[0079] In some embodiments, there are various ways to implement the battery replacement device 20. For example, a catapult-type battery replacement device 20 can eject the battery for replacement; there is also a grasping-type battery replacement device 20 that can grasp the battery for replacement. Therefore, the specific structure of the battery replacement device 20 will not be elaborated here.

[0080] In some embodiments, the vehicle-mounted controller 10 obtains the remaining total power of the rail vehicle battery pack. After the vehicle-mounted controller 10 obtains the remaining total power, based on the remaining total power, it can calculate the driving mileage that the remaining total power can support the rail vehicle to run. The vehicle-mounted controller 10 can also obtain the track length between the rail vehicle and the next platform. When the vehicle-mounted controller 10 obtains the driving mileage of the rail vehicle and the track length between the rail vehicle and the next platform, it can compare the two. If the driving mileage is less than the track length, it means that the remaining total power of the rail vehicle cannot maintain the operation of the rail vehicle to the next platform. At this time, the vehicle-mounted controller 10 issues a battery replacement instruction. The battery replacement device 20 installed on the rail vehicle or the platform, after receiving the battery replacement instruction sent by the vehicle-mounted controller 10, according to the battery replacement instruction, replaces the batteries in the rail vehicle battery pack in ascending order of the individual battery power until the driving mileage that the remaining total power can run is greater than or equal to the track length.

[0081] The rail vehicle battery replacement system 100 of the present invention can replace the underpowered batteries on the rail vehicle through the communication cooperation between the vehicle-mounted controller 10 and the battery replacement device 20. The replaced batteries can be charged on the platform when the rail vehicle arrives at the station, which greatly improves the operation efficiency of the rail vehicle.

[0082] In some embodiments, the batteries in the rail vehicle battery pack have battery temperature pins, and the temperature of the batteries can be monitored through the battery temperature pins to prevent the batteries from malfunctioning or exploding due to excessive temperature during charging and discharging.

[0083] In some embodiments, the vehicle-mounted controller 10 is also used to obtain the remaining power of each battery in the rail vehicle battery pack; based on the remaining power of each battery, obtain the remaining total power of the rail vehicle battery pack.

[0084] In some embodiments, the vehicle-mounted controller 10 is also used to obtain the mapping relationship between the driving distance of the rail vehicle and the battery power; based on the remaining total power and the mapping relationship, determine the driving mileage of the rail vehicle. The driving distance of the rail vehicle can establish a mapping relationship with the battery power of the rail vehicle. Here, the mapping relationship is that the rail vehicle consumes a certain battery power value for every certain distance traveled.

[0085] In some embodiments, a mapping relationship between the driving distance of a rail vehicle and the battery power of the rail vehicle can be established through a historical database. Based on historical operation data, the mapping relationship between the driving distance and the battery power of the rail vehicle in the historical data between the location where the rail vehicle is located and the next platform is obtained. Since it is the same section of the road, the mapping relationship obtained in this way can provide a relatively accurate data on the distance that the remaining total battery power of the current rail vehicle can travel.

[0086] In other embodiments, as the battery is continuously used, its discharge capacity will decrease. For example, the dischargeable proportion of a newly bought battery is 95%, and the discharge proportion gradually decreases as it is continuously used. Or, as the rail vehicle ages, its power consumption also increases. Therefore, it is necessary to refer to the mapping relationship between the battery power and the driving distance within the most recent preset time period, so as to obtain a more accurate required power. For example, taking the current moment as the end point and pushing back a certain preset time, the mapping relationship is established based on the battery power and the driving distance during this period. Since this period is the time period closest to the current moment, the battery charge and discharge efficiency problem can be almost ignored, and thus a relatively accurate data on the running distance that the remaining total battery power of the current battery can support can also be obtained through this mapping relationship.

[0087] In some embodiments, the vehicle-mounted controller 10 is further configured to obtain a first position where the rail vehicle is located and a second position where the next platform is located; and determine the track length according to the first position and the second position.

[0088] Wherein, the vehicle-mounted controller 10 can determine the track length through the following steps:

[0089] According to the first position and the second position, obtain at least two route arrangements between the first position and the second position; from the at least two route arrangements, screen out the route arrangement with the shortest track length as the route from the first position to the second position, that is, determine the minimum track length.

[0090] In some embodiments, since there may be more than one available route arrangement for the rail vehicle to travel from one location to another without affecting the operation of other rail vehicles, among multiple routes, the vehicle-mounted controller 10 on the rail vehicle preferentially selects the route arrangement with the shortest track length as the driving route of the rail vehicle, so that in case of a rail vehicle failure, the rail vehicle can reach the platform for maintenance as soon as possible.

[0091] The functions implemented by the rail vehicle battery replacement system 100 have been described in detail in the above rail vehicle battery replacement method, and will not be elaborated here.
