Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and more specifically to a method, device, vehicle and system for automatic battery replacement control of a rail transit vehicle. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has shown more and more types, not only covering long-distance land transportation, but also widely used in medium and short-distance urban public transportation. This type of rail transit vehicle running in urban public transportation is commonly known as "Yunba". Urban rail transit vehicles have good development prospects due to their energy saving and environmental protection. Urban rail transit is a large-capacity rapid public transportation system that uses electricity as the main power source and adopts a wheel-rail operation system. It is mainly responsible for barrier-free and short-distance passenger transportation, usually with light EMUs or trams as the transportation carrier, effectively alleviating the traffic pressure of dense passenger flow within the city.

[0003] Please refer to Figure 1 , Figure 1 The figure is a schematic diagram of the traditional rail transit vehicle battery replacement control method. In the traditional battery replacement control method, first, the rail transit vehicle includes a train control and management system (TCMS) and a battery management system (BMS). When the vehicle needs to replace the battery, the TCMS sends a battery replacement request to the BMS, and the BMS sends the battery replacement request to the battery replacement device. Then the driver operates the vehicle control system to put the vehicle into a ready state and receives a ready signal sent by the vehicle; the BMS sends the vehicle information to the battery replacement device; after the battery replacement device enters the ready state, the operator issues a battery replacement control command according to the intelligent control strategy recommended by the battery replacement monitoring system, and the battery replacement robot performs the battery replacement action after receiving the battery replacement control command until the battery replacement is completed.

[0004] The traditional battery swapping system uses a battery swapping device to automatically swap batteries. During the battery swapping process, manual selection of vehicle information, battery information, etc. is required on site. When there are many vehicles or batteries to be swapped, there are certain safety hazards. For example, when swapping batteries for multiple groups of vehicles or multiple carriages of a vehicle at the same time, it is easy to cause confusion in vehicle information or battery information, resulting in battery swapping errors.

[0076] In order to make the purpose, technical solutions and advantages of the present application more obvious, the example embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0077] Based on the aforementioned technical problems, the present application provides a method for controlling automatic battery replacement for rail transit vehicles, which is applied to an automatic battery replacement system for rail transit vehicles, wherein the automatic battery replacement system for rail transit vehicles includes ground battery replacement equipment and rail transit vehicles, wherein the ground battery replacement equipment includes a battery replacement server, at least one battery replacement device and at least one ground communication connection module, and the rail transit vehicle includes a train control and management system, at least one BMS and at least one on-board communication connection module, and the method includes: receiving a battery replacement signal, and controlling the rail transit vehicle to block the whole vehicle traction; controlling the on-board communication connection module to communicate with the ground communication connection module so that the battery replacement device performs battery replacement for the rail transit vehicle; receiving a notification of battery replacement completion sent by the BMS; controlling the on-board communication connection module to disconnect from the ground communication connection module, and releasing the whole vehicle blockade of the rail transit vehicle. Since the vehicle and the ground battery replacement device are in an interlocked state during the battery replacement process, rapid and automatic identification of vehicle information and matching of vehicle information can be achieved to realize real-time point-to-point communication between the vehicle and the ground battery replacement device. In addition, the rail transit vehicle automatic battery replacement control method, device and system of the present application can also realize real-time display and feedback of the battery replacement progress.

[0078] The following is a detailed description of the scheme of the rail transit vehicle automatic battery replacement control method according to the embodiment of the present application in conjunction with the accompanying drawings. The features of the various embodiments of the present application can be combined with each other without conflict.

[0079] Figure 2 FIG. 1 is a schematic flow chart showing a method for controlling automatic battery replacement of a rail transit vehicle according to an embodiment of the present application. Figure 2 As shown, the rail transit vehicle automatic battery replacement control method of the embodiment of the present application is applied to the rail transit vehicle automatic battery replacement system, the rail transit vehicle automatic battery replacement system includes ground battery replacement equipment and rail transit vehicles, the ground battery replacement equipment includes a battery replacement server, at least one battery replacement device and at least one ground communication connection module, the rail transit vehicle includes a TCMS, at least one BMS and at least one vehicle-mounted communication connection module. The rail transit vehicle automatic battery replacement control method 200 according to the embodiment of the present application may include the following steps S201, step S202, step 203 and step 204.

[0080] In step S201, a power replacement signal is received, and the rail transit vehicle is controlled to block the whole vehicle traction.

[0081] The main body of the embodiment is TCMS. The main functions of TCMS are to realize locomotive characteristic control, logic control, fault monitoring and self-diagnosis, and transmit information to the microcomputer display screen on the control console, so that the user can intuitively understand the real-time status of the locomotive.

[0082] Traction blocking is a vehicle protection function. When a rail transit vehicle is changing batteries, braking the vehicle may cause the battery change to fail, or even damage some equipment. To avoid this, a traction output blocking protection function is set on the rail transit vehicle. When changing batteries, blocking the traction of the entire vehicle can effectively prevent the failure of the battery change during the vehicle battery change process and avoid damage to the equipment.

[0083] In one example, the battery replacement signal includes a signal sent when the battery replacement knob of the rail transit vehicle is valid. For example, when the battery needs to be replaced, the user can manually rotate the battery replacement knob to a valid position. Here, when the battery replacement knob is in a valid state, a battery replacement signal will be generated and sent to the TCMS.

[0084] In a specific example, the battery-changing knobs can be set in the cabs at both ends of the rail transit vehicle. When TCMS detects that any battery-changing knob is valid, it can send a battery-changing request to the BMS.

[0085] In step 202, the on-board communication connection module is controlled to establish a communication connection with the ground communication connection module, so that the battery exchange device exchanges battery for the rail transit vehicle.

[0086] The on-board communication connection module of the rail transit vehicle is connected to the ground communication connection module of the battery exchange device to achieve point-to-point communication connection between the rail transit vehicle and the battery exchange device. During the battery exchange process, due to the point-to-point communication connection between the rail transit vehicle and the battery exchange device, and the vehicle has been blocked and towed, the vehicle cannot brake. At this time, the vehicle and the ground battery exchange device are in an interlocked state to avoid errors during battery exchange.

[0087] In some application scenarios, the rail transit vehicle can be driven to a preset battery swapping position, and then the entire vehicle is towed and blocked, and the ground communication connection module is moved to the battery swapping position by lifting and lowering, and communicated with the on-board communication connection module. In other application scenarios, the battery swapping device and the ground communication connection module can be kept stationary at the battery swapping position, and then the rail transit vehicle can be lifted and lowered to enable the on-board communication connection module to communicate with the ground communication connection module, thereby achieving battery swapping.

[0088] In one example, after TCMS controls the on-board communication connection module to establish communication connection with the ground communication connection module, the method further includes: A1, sending a battery replacement request to the BMS, so that the BMS sends the battery replacement request to the battery replacement server; A2, receiving a response from the battery replacement server agreeing to the battery replacement forwarded by the BMS; A3, receiving a notification of battery replacement sent by the BMS.

[0089] Here, after TCMS sends a battery replacement request to the BMS, if no response is received within a certain time interval, TCMS will continue to send battery replacement requests to the BMS. After receiving a response from the battery replacement server forwarded by the BMS agreeing to the battery replacement, TCMS will stop sending battery replacement requests to the BMS.

[0090] In step 203, a notification of battery replacement completion sent by the BMS is received.

[0091] During the battery swap period, the battery swap server sends the battery swap progress to the BMS. When the battery swap progress is 100%, the BMS will detect the connection status of the new battery's connectors, water pipes, and mounting clips, and provide feedback on whether it is effective. If there is no problem, a notification of battery swap completion will be sent to the server, so that the server can send a control command to the battery swap device to complete the battery swap and disconnect. At the same time, the BMS needs to send a notification of battery swap completion to the TCMS. According to the notification of battery swap completion sent by the BMS, the TCMS can perform the next action, such as disconnecting the vehicle-mounted communication connection module from the ground communication connection module to release the vehicle traction blockade.

[0092] The battery to be replaced and the new battery in the embodiment of the present invention may be a battery pack.

[0093] In one example, before receiving the notification of battery replacement completion sent by the BMS, the method also includes: receiving new battery information after battery replacement sent by the BMS; wherein the new battery information includes at least one of the following: battery type, rated voltage, rated power and remaining available battery power of the battery pack. For rail transit vehicles, it does not necessarily support only one type of battery, but may support several types of batteries, as long as the parameters are guaranteed to meet the requirements of vehicle driving, which can make the vehicle more compatible. Since the parameters of the new battery and the battery to be replaced are not necessarily exactly the same, after the battery replacement is completed, the BMS needs to notify the TCMS of the various parameters of the new battery.

[0094] In step 204, the vehicle-mounted communication connection module is controlled to be disconnected from the ground communication connection module, and the whole vehicle blockade of the rail transit vehicle is released.

[0095] After the battery replacement is completed, the whole vehicle blockade of the rail transit vehicle can be released so that the rail transit vehicle can brake and continue to run. It is worth mentioning that rail transit vehicles can have multiple vehicles in groups. In this case, each car is equipped with a battery, a BMS and an on-board communication connection module. Correspondingly, the automatic battery replacement system for rail transit vehicles is also provided with multiple battery replacement devices and multiple ground communication connection modules, wherein the ground communication connection modules correspond one to one to the battery replacement devices. During battery replacement, each on-board communication connection module is communicated with a ground communication connection module, thereby realizing battery replacement for multiple vehicles.

[0096] In the embodiment of the present application, due to the real-time point-to-point communication between the vehicle and the ground battery swapping device, the vehicle and the ground battery swapping device are in an interlocked state during the battery swapping process, which can achieve rapid and automatic identification of vehicle information and matching of vehicle information, thereby avoiding errors during battery swapping.

[0097] Figure 3 FIG. 1 is a schematic flow chart showing a method for controlling automatic battery replacement of a rail transit vehicle according to an embodiment of the present application. Figure 3 As shown, the rail transit vehicle automatic battery replacement control method of the embodiment of the present application can be applied to the rail transit vehicle automatic battery replacement system, the rail transit vehicle automatic battery replacement system includes ground battery replacement equipment and rail transit vehicles, the ground battery replacement equipment includes a battery replacement server, at least one battery replacement device and at least one ground communication connection module, the rail transit vehicle includes a TCMS, at least one BMS and at least one vehicle-mounted communication connection module. The rail transit vehicle automatic battery replacement control method 300 according to the embodiment of the present application may include the following steps S301, S302 and S303.

[0098] In step 301, a battery replacement request sent by TCMS is received, and the battery replacement request is forwarded to the battery replacement server, so that the battery replacement server controls the battery replacement device to replace the battery for the rail transit vehicle; wherein the battery replacement request is sent by the TCMS to the BMS after the on-board communication connection module is communicated with the ground communication connection module.

[0099] The execution subject of the embodiment of the present invention is a BMS.

[0100] In one example, after receiving a battery replacement request sent by TCMS and forwarding the battery replacement request to the battery replacement server, the method further includes: B1, sending battery information of the battery to be replaced to the battery replacement server, and receiving battery information of the new battery sent by the battery replacement server to determine whether the battery to be replaced matches the new battery; B2, forwarding the battery information of the new battery to the TCMS. For rail transit vehicles, it does not necessarily support only one type of battery, but may support several types of batteries, as long as the parameters meet the requirements of vehicle driving, so that the vehicle compatibility can be better. Since the new battery and the battery to be replaced may not be exactly the same in terms of parameters, before the battery is replaced, the BMS can send the battery information of the battery to be replaced to the battery replacement server for confirmation. At the same time, the battery replacement server will also send the battery information of the new battery to the BMS to confirm whether the new battery can or cannot match the rail transit vehicle. If it matches, the next step will be executed. If it does not match, a prompt that the battery cannot be replaced can be sent to the user.

[0101] In one example, after receiving a battery replacement request sent by TCMS and forwarding the battery replacement request to the battery replacement server, the method further includes: sending a discharge not allowed signal to the TCMS and disconnecting the discharge positive and negative contactors of the battery to be replaced. During the battery replacement process, since the battery is in an unusable state, it is necessary to disconnect the load that needs power supply, such as the air conditioner in the vehicle.

[0102] In another example, after sending a discharge disallowed signal to the TCMS and disconnecting the discharge positive and negative contactors of the battery to be replaced, the method further includes: C1, sending a notification of battery replacement to the TCMS; C2, receiving a notification of battery replacement progress sent by the battery replacement server, and forwarding the notification of battery replacement progress to the TCMS. The embodiments of the present application can realize real-time display and feedback of battery replacement progress, so that users can understand the battery replacement progress at any time and improve user experience.

[0103] In one example, a battery swap request sent by TCMS is received, and the battery swap request is forwarded to the battery swap server so that the battery swap server controls the battery swap device to swap batteries for rail transit vehicles, including: D1, receiving the battery swap request sent by TCMS, and forwarding the battery swap request to the battery swap server; D2, receiving the response of the battery swap server agreeing to the battery swap, and forwarding the response to the TCMS; D3, receiving the handshake signal and identification signal of the battery swap server and making a corresponding response to the handshake signal and identification signal; D4, sending a battery swap ready signal to the battery swap server, so that the battery swap server controls the battery swap device to swap batteries for rail transit vehicles.

[0104] In step S302, a notification of completion of battery replacement is sent to the battery replacement server so that the server controls the ground communication connection module to disconnect from the vehicle-mounted communication connection module.

[0105] In one example, before sending a notification of battery replacement completion to the battery replacement server, the method further includes: detecting that at least one of the following items of the new battery is in a valid state: the connector connection is valid, the water pipe connection is valid, and the installation clip connection is valid. Specifically, when the above information of the new battery is in a valid state, it means that there is no abnormality in the new battery and the battery replacement is successful. At this time, the BMS can send a notification of battery replacement completion to the battery replacement server so that the battery replacement server performs the next step; if any of the above information of the new battery is not in a valid state, it means that there is an abnormality in the new battery, the battery replacement fails, etc. At this time, a prompt of abnormal battery replacement can be sent to the user.

[0106] In step S303, a notification of battery replacement completion is sent to the TCMS, so that the TCMS controls the on-board communication connection module to disconnect from the ground communication connection module and releases the whole vehicle blockade of the rail transit vehicle.

[0107] In one example, after sending a notification of battery replacement completion to the TCMS, the method further includes: controlling the high voltage of the vehicle compartment where the BMS is located to be powered on. At this time, the new battery can be used to power the loads in the vehicle, for example, to power the air conditioner in the vehicle.

[0108] In the embodiment of the present application, due to the real-time point-to-point communication between the vehicle and the ground battery swapping device, the vehicle and the ground battery swapping device are in an interlocked state during the battery swapping process, which can achieve rapid and automatic identification of vehicle information and matching of vehicle information, thereby avoiding errors during battery swapping.

The rail transit vehicle automatic battery replacement control method 400 according to the embodiment of the present application may include the following steps S401, S402, S403 and S404:

[0110] In step S401, the ground communication connection module is controlled to establish communication connection with the vehicle-mounted communication connection module.

[0111] The execution subject of the embodiment of the present application is a battery swap server. After receiving the battery swap request, the battery swap server performs battery swap for the rail transit vehicle according to the content of the battery swap request.

[0112] In the embodiment of the present application, due to the real-time point-to-point communication between the vehicle and the ground battery swapping device, the vehicle and the ground battery swapping device are in an interlocked state during the battery swapping process, which can realize rapid and automatic identification of vehicle information and matching of vehicle information, thereby avoiding errors during battery swapping.

[0113] In step S402, a battery replacement request sent by the BMS is received, and the battery replacement device is controlled to perform battery replacement for the rail transit vehicle according to the battery replacement request.

[0114] In one example, before controlling the battery replacement device to replace the battery for the rail transit vehicle, the method also includes: F1, receiving the battery information of the battery to be replaced sent by the BMS; F2, sending the battery information of the new battery for this battery replacement to the BMS to determine whether the new battery matches the battery to be replaced. For rail transit vehicles, it does not necessarily support only one type of battery, but may support several types of batteries. As long as the parameters meet the requirements of vehicle driving, the vehicle compatibility can be better. Since the new battery and the battery to be replaced may not be exactly the same in terms of parameters, before the battery is replaced, the BMS can send the battery information of the battery to be replaced to the battery replacement server for confirmation. At the same time, the battery replacement server will also send the battery information of the new battery to the BMS to confirm whether the new battery can or cannot match the rail transit vehicle. If it matches, the next step will be executed. If it does not match, a prompt that the battery cannot be replaced can be sent to the user.

[0115] In one example, controlling the battery swap device to swap batteries for the rail transit vehicle includes: F3, sending a notification of battery swapping to the BMS; F4, controlling the battery swap device to start the battery swapping action; F5, monitoring the battery swapping progress of the rail transit vehicle and forwarding the battery swapping progress to the BMS. The BMS forwards the battery swapping progress to the TCMS, so that the user can understand the battery swapping progress in real time, improving the user experience.

[0116] In one example, after receiving the battery swap request sent by the BMS, the battery swap server establishes a communication connection with the BMS. The specific process is as follows: The method also includes: E1, sending a response agreeing to the battery swap to the BMS; E2, sending a handshake signal and an identification signal to the BMS through the ground communication module, and receiving the BMS's reply to the handshake signal and the identification signal.

[0117] In one example, after receiving the battery replacement request sent by the BMS, the method further includes: G1, receiving a battery replacement ready signal sent by the BMS; G2, sending a battery replacement ready signal to the BMS.

[0118] In step S403, a battery replacement completion signal sent by the BMS is received, and it is detected whether the battery replacement device returns to its original position.

[0119] During the battery swapping process, the rail transit vehicle can be driven to the preset battery swapping position, and then the entire vehicle is towed and blocked, and then the ground communication connection module is moved to the battery swapping position by lifting, so that the ground communication connection module and the vehicle-mounted communication connection module can be connected in communication. In other application scenarios, the battery swapping device and its ground communication connection module can be kept at the battery swapping position, and then the vehicle-mounted communication connection module and the ground communication connection module can be connected in communication by lifting the rail transit vehicle, so that the battery swapping can be realized.

[0120] In step S404, when the battery replacement device has returned to its original position, a notification of battery replacement completion is sent to the BMS.

[0121] If the battery replacement device has returned to its original position, it means that the battery replacement is successful. At this time, a notification of battery replacement completion can be sent to the BMS so that the BMS can proceed to the next action.

[0122] In the embodiment of the present application, due to the real-time point-to-point communication between the vehicle and the ground battery swapping device, the vehicle and the ground battery swapping device are in an interlocked state during the battery swapping process, which can achieve rapid and automatic identification of vehicle information and matching of vehicle information, thereby avoiding errors during battery swapping.
