Description

Technical Field

[0001] The present invention relates to the field of new energy battery swapping control technology, and particularly to a method and a screening method for state transmission of vehicle-end devices, a system and a medium. Background Art

[0002] Due to various reasons, it is possible that the vehicle-end device is offline and out of the monitoring range. It is difficult for the Telematics Service Provider (TSP) platform to determine whether the reason for the offline is that the vehicle has turned off and powered down, or whether the vehicle-end device itself has failed due to equipment failure or damage. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that it is difficult for the TSP platform to determine whether the reason for the offline is that the vehicle has turned off and powered down or whether the vehicle-end device itself has failed, and to provide a method and a screening method for state transmission of vehicle-end devices, a system and a medium.

[0004] The present invention solves the above technical problem through the following technical solutions:

[0005] In a first aspect, the present disclosure provides a method for state transmission of vehicle-end devices. The state transmission method is applied to a vehicle, and each vehicle includes a battery swapping controller. The state transmission method includes:

[0006] When the automatic wake-up function of the battery swapping controller is enabled, if the continuous sleep duration is greater than a preset first duration threshold, the battery swapping controller automatically wakes up and sends a login message to the TSP platform so that the TSP platform can obtain the online state of the vehicle-end device.

[0007] In this solution, when the battery swapping controller on the vehicle is normally powered on and logs in to the TSP platform, it will send a login message. When the TSP platform receives the login message, it can know that the current state of the corresponding vehicle is normal. The TSP platform can record the reception time points of the login messages of several subordinate vehicles and screen out the vehicles with too long offline time as target vehicles based on the reception time points of the login messages of each vehicle, so as to perform abnormal tracking and investigation on the target vehicles. By using the automatic wake-up function of the battery swapping controller, the power consumption of the vehicle can be reduced, and on the basis of basically not increasing the power consumption of the vehicle, the range of vehicles that need to be tracked and investigated can be efficiently and quickly reduced, which can greatly reduce the investigation time and the workload of after-sales maintenance, and is beneficial to the rapid tracking and response of vehicle-end device failures.

[0008] Optionally, after the step of sending the login message to the TSP platform, the state transmission method further includes:

[0009] The battery swapping controller resumes sleeping.

[0010] In this solution, after the battery swapping controller sends a login message to the vehicle networking platform, it goes back to sleep, further reducing the power consumption of the vehicle, avoiding the unnecessary long-term wake-up or standby state of the battery swapping controller, and reducing the risk of power loss for vehicles parked for a long time without use.

[0011] Optionally, the first duration threshold is set to 24 hours.

[0012] In this solution, the first duration threshold is set to 24 hours, that is, the vehicle sends a login message to the vehicle networking platform once a day, keeping the sending frequency at an appropriate level, which not only avoids the frequent wake-up of the battery swapping controller to send login messages, but also avoids the vehicle being offline for too long and the vehicle networking platform being unable to master the vehicle status, and thus unable to judge the reason for the disconnection of the vehicle-side device.

[0013] In a second aspect, the present disclosure provides a screening method for vehicle-side devices. The screening method is applied to a vehicle networking platform and includes:

[0014] Receiving login messages sent by battery swapping controllers on several vehicles and recording the receiving time points;

[0015] Statistical analysis of the duration from the latest receiving time point of each vehicle to the current time point. Vehicles with the duration greater than a preset second duration threshold are determined as target vehicles for abnormal tracking and investigation.

[0016] In this solution, when the vehicle networking platform receives the login message of a vehicle, it can know that the current state of the corresponding vehicle is normal. The vehicle networking platform can record the receiving time points of the login messages of several subordinate vehicles and screen out the vehicles with too long offline time as target vehicles according to the receiving time points of the login messages of each vehicle for abnormal tracking and investigation. By using the automatic wake-up function of the battery swapping controller, the power consumption of the vehicle can be reduced, and on the basis of basically not increasing the power consumption of the vehicle, the range of vehicles that need to be tracked and investigated can be efficiently and quickly reduced, which can greatly reduce the investigation time and the workload of after-sales maintenance, and is conducive to the rapid tracking and response of vehicle-side device failures.

[0017] Optionally, the second duration threshold is set to 24 hours.

[0018] In this solution, the second duration threshold is set to 24 hours, and the second duration threshold should be greater than or equal to the first duration threshold, that is, the vehicle networking platform screens out the vehicles with offline time exceeding one day as target vehicles, that is, the vehicles that do not wake up automatically and send login messages normally are the target vehicles that need to be tracked and excluded, and the vehicles with failures must be within the range of target vehicles.

[0019] In a third aspect, the present disclosure provides a status transfer system for vehicle-side devices. The status transfer system is applied to a vehicle, and each vehicle includes the status transfer system. The status transfer system includes:

[0020] A battery swapping controller, configured to automatically wake up and send a login message to the vehicle networking platform when the automatic wake-up function is enabled and the continuous sleep duration is greater than a preset first duration threshold, so that the vehicle networking platform can obtain the online status of the vehicle-side device.

[0021] Optionally, the battery swapping controller is further configured to resume sleeping after sending the login message to the vehicle networking platform;

[0022] And / or,

[0023] The first duration threshold is set to 24 hours.

[0024] In a fourth aspect, the present disclosure provides a screening system for vehicle-side devices. The screening system is applied to a vehicle networking platform. The screening system includes:

[0025] A receiving module, configured to receive login messages sent by battery swapping controllers on several vehicles and record the receiving time points;

[0026] A statistical screening module, configured to count the duration from the latest receiving time point of each vehicle to the current time point, and determine the vehicle with the duration greater than a preset second duration threshold as a target vehicle for abnormal tracking and investigation.

[0027] Optionally, the second duration threshold is set to 24 hours.

[0028] In a fifth aspect, the present disclosure provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it implements the aforementioned status transfer method for vehicle-side devices and / or implements the aforementioned screening method for vehicle-side devices.

[0029] The positive and progressive effects of the present invention are as follows: When the battery swapping controller on the vehicle powers on normally and logs in to the vehicle networking platform, it will send a login message. When the vehicle networking platform receives the login message, it can know that the current status of the corresponding vehicle is normal. The vehicle networking platform can record the receiving time points of the login messages received from several subordinate vehicles and screen out the vehicles with too long offline time as target vehicles according to the receiving time points of the login messages of each vehicle for abnormal tracking and investigation. By using the automatic wake-up function of the battery swapping controller, it can reduce the power consumption of the vehicle, efficiently and quickly narrow the range of vehicles that need to be tracked and investigated with little increase in the power consumption of the vehicle, greatly reduce the investigation time and the workload of after-sales maintenance, and is conducive to the rapid tracking and response of vehicle-side device failures.

[0035] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0036] Embodiment 1

[0037] This embodiment provides a status transfer method for vehicle - side devices. The status transfer method is applied to vehicles, and each vehicle includes a battery - swapping controller. Refer to Figure 1 , and the status transfer method includes:

[0038] S11. When the automatic wake - up function is enabled, if the continuous sleep duration is greater than a preset first duration threshold, the battery - swapping controller automatically wakes up and sends a login message to the vehicle networking platform so that the vehicle networking platform can obtain the online status of the vehicle - side device.

[0039] Among them, the battery - swapping controller is installed on the vehicle - side. When the battery - swapping controller is normally powered on and logs in to the vehicle networking platform, it will send a login message (baseinfo). The vehicle networking platform can master the online operation situation of the vehicle according to the login message and continuous monitoring data.

[0040] When the battery swap controller is offline for a long time, it is difficult for the Internet of Vehicles platform to determine whether the data cannot be transmitted because the vehicle is not in use or because of equipment failure. Through timed automatic wake-up, if the continuous sleep time is greater than the preset first time threshold, such as more than 24 hours without being online, the battery swap controller automatically wakes up from the sleep state and automatically logs in to the Internet of Vehicles platform, which can help the Internet of Vehicles platform make a quick judgment on whether the device functions normally. For example, if the vehicle has not been operated by battery swapping for many consecutive days, and no battery swap controller has logged in to the Internet of Vehicles platform to send a login message, it can be listed as a suspected target of terminal abnormality, and after-sales personnel can be required to further trace and verify.

[0041] The first duration threshold may be set according to actual needs to take into account both the need for vehicle status monitoring and the need to reduce the vehicle's power consumption.

[0042] At present, a certain operator has nearly 300 battery swap stations in operation in various places, and 30,000 battery swap vehicles have been registered on the network. The average number of active vehicles per day is nearly 13,000. There are many reasons for the abnormality of the battery swap controller terminal, such as hardware failure, software failure, network abnormality, SIM (Subscriber Identity Module) card traffic abnormality, etc. It is very laborious to locate such a large number of online vehicle terminal abnormalities. The simple screening method of online time interval can quickly narrow the scope of vehicles that need to be tracked and investigated, which can greatly reduce the investigation time and after-sales workload, and is conducive to the rapid tracking and response of problems.

[0043] In this embodiment, the battery swap controller on the vehicle will send a login message when it is powered on normally and logs in to the Internet of Vehicles platform. When the Internet of Vehicles platform receives the login message, it will know that the current status of the corresponding vehicle is normal. The Internet of Vehicles platform can record the receiving time point of the login message of several vehicles under its jurisdiction and filter out vehicles that have been offline for too long as target vehicles according to the receiving time point of the login message of each vehicle, so as to track and investigate the target vehicles for abnormalities. By utilizing the automatic wake-up function of the battery swap controller, the vehicle's energy consumption can be reduced. On the basis of basically not increasing the vehicle's energy consumption, the scope of vehicles that need to be tracked and investigated can be efficiently and quickly narrowed, which can greatly reduce the investigation time and the workload of after-sales maintenance, and is conducive to the rapid tracking and response of vehicle-side equipment failures.

[0044] In one embodiment, referring to Figure 2 After the step of "sending a login message to the Internet of Vehicles platform" in step S11, the state transfer method further includes:

[0045] S12, the battery swap controller goes back to sleep.

[0046] Among them, the battery swap controller can go back to sleep when there are no other tasks to be performed to save energy.

[0047] In this embodiment, after the battery swapping controller sends a login message to the vehicle networking platform, it goes back to sleep, further reducing the power consumption of the vehicle, avoiding unnecessary long-term wake-up or standby state of the battery swapping controller, and reducing the risk of power loss for vehicles parked for a long time without use.

[0048] In one embodiment, the first duration threshold is set to 24 hours.

[0049] In this embodiment, the first duration threshold is set to 24 hours, that is, the vehicle sends a login message to the vehicle networking platform once a day, keeping the sending frequency at an appropriate level, which not only avoids the battery swapping controller from frequently waking up to send login messages, but also avoids the vehicle networking platform being unable to master the vehicle status for too long and thus unable to judge the reason for the disconnection of the vehicle-end device.

[0050] Embodiment 2

[0051] This embodiment provides a screening method for vehicle-end devices. The screening method is applied to the vehicle networking platform. Referring to Figure 3 , the screening method includes:

[0052] S21. Receive the login messages sent by the battery swapping controllers on several vehicles and record the receiving time points.

[0053] S22. Statistically calculate the duration from the latest receiving time point of each vehicle to the current time point, and determine the vehicles with the duration greater than the preset second duration threshold as target vehicles for abnormal tracking and investigation.

[0054] Among them, the battery swapping controller is installed at the vehicle end. When the battery swapping controller is normally powered on and logs in to the vehicle networking platform, it will send a login message (baseinfo). The vehicle networking platform can master the online operation situation of the vehicle according to the login message and continuous monitoring data.

[0055] When the battery swapping controller is offline for a long time, it is difficult for the vehicle networking platform to judge whether it is due to the vehicle not being used or due to equipment failure that data cannot be transmitted. Through timed automatic wake-up, if the continuous sleep duration is greater than the preset first duration threshold, for example, if it has not been online for more than 24 hours, the battery swapping controller will automatically wake up from the sleep state and automatically log in to the vehicle networking platform, which can help the vehicle networking platform quickly judge whether the device function is normal. For example, if the vehicle has not been swapped for operation for several consecutive days and no battery swapping controller logs in to the vehicle networking platform to send a login message, it can be listed as a suspected target of terminal abnormality, and after-sales personnel can be required to further trace and verify.

[0056] Currently, an operator already has nearly 300 operation and replacement stations in various regions, and 30,000 replacement electric vehicles are registered and networked. The average daily active vehicle count is nearly 13,000. There are many reasons for abnormal conditions in the replacement controller terminals, such as hardware failures, software failures, network anomalies, abnormal SIM (Subscriber Identity Module) card traffic, etc. To locate abnormal problems for such a large number of online vehicle terminals, the workload is extremely large. Using a simple screening method based on the online duration interval can quickly narrow down the scope of vehicles that need to be tracked and investigated, greatly reducing the investigation time and the workload of after-sales service, and facilitating the rapid tracking and response to problems.

[0057] The second duration threshold can be set according to actual needs to screen suitable target vehicles through the offline time.

[0058] In this embodiment, when the vehicle networking platform receives the login message of a vehicle, it can know that the current status of the corresponding vehicle is normal. The vehicle networking platform can record the reception time points of the login messages of several subordinate vehicles and screen out the vehicles with too long offline time as target vehicles according to the reception time points of the login messages of each vehicle, so as to conduct abnormal tracking and investigation on the target vehicles. Utilizing the automatic wake-up function of the replacement controller can reduce the power consumption of the vehicle, and efficiently and quickly narrow down the scope of vehicles that need to be tracked and investigated basically without increasing the power consumption of the vehicle, greatly reducing the investigation time and the workload of after-sales maintenance, and facilitating the rapid tracking and response to equipment failures on the vehicle side.

[0059] In one embodiment, the second duration threshold is set to 24 hours.

[0060] In this embodiment, the second duration threshold is set to 24 hours. The second duration threshold should be greater than or equal to the first duration threshold, that is, the vehicle networking platform screens out the vehicles with an offline time exceeding one day as target vehicles, that is, the vehicles that do not wake up automatically and send login messages normally are the target vehicles that need to be tracked and excluded, and the vehicles with failures must be within the scope of the target vehicles.

[0061] Embodiment 3

[0062] This embodiment provides a status transfer system for vehicle-side equipment. The status transfer system is applied to vehicles, and each vehicle includes a status transfer system. Refer to Figure 4 , and the status transfer system includes:

[0063] A replacement controller 31, configured to, when the automatic wake-up function is enabled, if the continuous sleep duration is greater than a preset first duration threshold, automatically wake up and send a login message to the vehicle networking platform to enable the vehicle networking platform to obtain the online status of the vehicle side.

[0064] Among them, the battery swap controller is installed on the vehicle side. When the battery swap controller is powered on normally and logs in to the Internet of Vehicles platform, it will send a login message (baseinfo). The Internet of Vehicles platform can grasp the online operation status of the vehicle based on the login message and continuous monitoring data.

[0065] When the battery swap controller is offline for a long time, it is difficult for the Internet of Vehicles platform to determine whether the data cannot be transmitted because the vehicle is not in use or because of equipment failure. Through timed automatic wake-up, if the continuous sleep time is greater than the preset first time threshold, such as more than 24 hours without being online, the battery swap controller automatically wakes up from the sleep state and automatically logs in to the Internet of Vehicles platform, which can help the Internet of Vehicles platform make a quick judgment on whether the device functions normally. For example, if the vehicle has not been operated by battery swapping for many consecutive days, and no battery swap controller has logged in to the Internet of Vehicles platform to send a login message, it can be listed as a suspected target of terminal abnormality, and after-sales personnel can be required to further trace and verify.

[0066] The first duration threshold may be set according to actual needs to take into account both the need for vehicle status monitoring and the need to reduce the vehicle's power consumption.

[0067] At present, a certain operator has nearly 300 battery swap stations in operation in various places, and 30,000 battery swap vehicles have been registered on the network. The average number of active vehicles per day is nearly 13,000. There are many reasons for the abnormality of the battery swap controller terminal, such as hardware failure, software failure, network abnormality, SIM (Subscriber Identity Module) card traffic abnormality, etc. It is very laborious to locate such a large number of online vehicle terminal abnormalities. The simple screening method of online time interval can quickly narrow the scope of vehicles that need to be tracked and investigated, which can greatly reduce the investigation time and after-sales workload, and is conducive to the rapid tracking and response of problems.

[0068] In this embodiment, the battery swap controller on the vehicle will send a login message when it is powered on normally and logs in to the Internet of Vehicles platform. When the Internet of Vehicles platform receives the login message, it will know that the current status of the corresponding vehicle is normal. The Internet of Vehicles platform can record the receiving time point of the login message of several vehicles under its jurisdiction and filter out vehicles that have been offline for too long as target vehicles according to the receiving time point of the login message of each vehicle, so as to track and investigate the target vehicles for abnormalities. By utilizing the automatic wake-up function of the battery swap controller, the vehicle's energy consumption can be reduced. On the basis of basically not increasing the vehicle's energy consumption, the scope of vehicles that need to be tracked and investigated can be efficiently and quickly narrowed, which can greatly reduce the investigation time and the workload of after-sales maintenance, and is conducive to the rapid tracking and response of vehicle-side equipment failures.

[0069] In one embodiment, the battery swap controller 31 is also used to go back to sleep after sending a login message to the Internet of Vehicles platform.

[0070] Among them, the battery swapping controller can go back to sleep when there are no other tasks to be performed, so as to save electric energy.

[0071] In this embodiment, after sending a login message to the vehicle networking platform, the battery swapping controller goes back to sleep, further reducing the power consumption of the vehicle, avoiding the battery swapping controller from staying awake or on standby for an unnecessary long time, and reducing the risk of power loss for vehicles parked without use for a long time.

[0072] In one embodiment, the first duration threshold is set to 24 hours.

[0073] In this embodiment, the first duration threshold is set to 24 hours, that is, the vehicle sends a login message to the vehicle networking platform once a day, keeping the sending frequency at an appropriate level, which not only avoids the battery swapping controller from waking up frequently to send login messages, but also avoids the vehicle networking platform being unable to master the vehicle status for too long and thus unable to judge the reason for the disconnection of the vehicle-end device.

[0078] Among them, the battery swapping controller is installed on the vehicle end. When the battery swapping controller is normally powered on and logs in to the vehicle networking platform, it will send a login message (baseinfo). The vehicle networking platform can master the online operation situation of the vehicle according to the login message and continuous monitoring data.

[0079] When the battery swapping controller is offline for a long time, it is difficult for the vehicle networking platform to judge whether it is due to the vehicle not being used or due to equipment failure that data cannot be transmitted. Through timed automatic wake-up, if the continuous sleep duration is greater than the preset first duration threshold, for example, if it has not been online for more than 24 hours, the battery swapping controller will automatically wake up from the sleep state and automatically log in to the vehicle networking platform, which can help the vehicle networking platform quickly judge whether the device function is normal. For example, if the vehicle has not undergone battery swapping operation for several consecutive days and no battery swapping controller logs in to the vehicle networking platform to send a login message, it can be listed as a suspected target of terminal abnormality, and after-sales personnel can be required to further trace and verify.

[0080] At present, an operator already has nearly 300 operation swapping stations in various places, and 30,000 swapping vehicles are registered on the network. The average daily active vehicle count is nearly 13,000. There are many reasons for the abnormality of the swapping controller terminal, such as hardware failure, software failure, network exception, abnormal SIM (Subscriber Identity Module) card traffic, etc. To locate the abnormal problems of such a large number of online vehicle terminals, the workload is very large.
