[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0064] The embodiments of the present application provide a state determination method, apparatus, target device, and computer-readable storage medium. Specifically, the state determination method of the embodiments of the present application can be executed by a target device, wherein the target device can be a terminal. The terminal can be a smart phone, a tablet computer, a laptop computer, a touch screen, a game console, a personal computer (PC, Personal Computer), and a personal digital assistant (Personal Digital Assistant, PDA) and other terminals.

[0065] The embodiments of the present application provide a state determination method. Figure 1 FIG. 1 is a flowchart of a state determination method provided by an exemplary embodiment of the present application. In this embodiment, the target device is used as the execution subject for explanation. Figure 1 As shown, the state determination method includes the following steps:

[0066] S101. When a target device is connected to an information transmission interface in a vehicle, status data of a battery of the vehicle is collected through the information transmission interface.

[0067] The target device is a device that exists independently of the vehicle, and can be a node device in the target network. The target device is connected to the vehicle via an information transmission interface. The information transmission interface is a physical interface on the vehicle, through which the status data of the battery on the vehicle can be collected.

[0068] The type of physical interface can be set according to actual conditions. For example, the physical interface can be an on-board diagnostic system interface (On-Board Diagnostics, OBD) or a USB interface, that is, the information transmission interface can be an on-board diagnostic system interface or a USB interface, which is not limited in the embodiments of the present application.

[0069] Since the vehicle's battery management system and on-board automatic diagnostic system interface operate normally and do not enter a sleep state when the vehicle is in low power consumption mode, when the information transmission interface is the on-board automatic diagnostic system interface, the battery status data can be collected even if the vehicle is in low power consumption mode, and the battery status can be monitored based on the status data.

[0070] The battery status data refers to data that can be used to indicate the safety status of the battery, which may be data in a battery management system (BMS).

[0071] The type of status data can be set according to actual conditions. For example, the battery status data may include at least one of the battery voltage, current, temperature, total capacity, remaining capacity, charging current, discharging current, and charging and discharging time. The embodiments of the present application are not limited here.

[0072] In some embodiments, before collecting the status data of the battery of the vehicle through the information transmission interface, the user can first connect the target device to the information transmission interface. When the target device detects that it is connected to the information transmission interface, it can draw power through the information transmission interface and perform initialization processing. The initialization processing includes reading at least one of the vehicle identification number (Vehicle Identification Number, VIN) and the identification of the battery in the vehicle, so that when the target device subsequently collects the status data, it can use the identification code and / or the battery identification as the data identification of the status data, and then send the status data with the data identification to the gateway.

[0073] In some embodiments, before collecting the status data of the battery of the vehicle through the information transmission interface, the method further includes:

[0074] When a connection with the information transmission interface is detected, a channel selection operation is performed;

[0075] On the selected channel, a network access request is sent to the gateway, triggering the gateway to add the target device to the target network based on the network access request.

[0076] The process of adding the target device to the target network may also be referred to as the process of networking the target device with the gateway, which may also be a part of the target device initialization. That is, the initialization in the embodiment of the present application may include at least one of adding the target device to the target network, reading the vehicle identification number (VIN) and the identification of the battery in the vehicle.

[0077] After executing the channel selection operation, the target device can select a channel, which is called the selected channel. Then, on the selected channel, it sends a network access request to the gateway. After receiving the network access request, the gateway verifies the target device according to the network access request. When the verification is successful, it sends a connection response to the target device. The target device then establishes a connection with the gateway based on the connection response, thereby adding the target device to the target network where the gateway is located.

[0078] It is understandable that after obtaining the selected channel, the target device can determine whether the selected channel is occupied to avoid interference and conflict. At this time, on the selected channel, a network access request is sent to the gateway, including:

[0079] Determine whether a preamble exists in the selected channel;

[0080] If there is no preamble, a network access request is sent to the gateway on the selected channel.

[0081] Among them, when the selected channel has a preamble code, it means that the channel has been used by other devices. If this channel is selected, it may cause conflicts and interference, affecting the transmission of status data. Therefore, in the embodiment of the present application, when there is no preamble code on the selected channel, a network access request is sent to the gateway on the selected channel to achieve data interaction with the gateway on an unoccupied channel to avoid conflicts and interference.

[0082] In some embodiments, after determining whether the selected channel has a preamble, the method further includes:

[0083] If the selected channel has a preamble, the target device backs off and waits;

[0084] Get the backoff waiting times. If the backoff waiting times are equal to the preset times, the target device will no longer perform the channel selection operation.

[0085] If the backoff waiting times are less than the preset times, determine whether the current backoff index is equal to the preset value;

[0086] If the current backoff index is equal to the preset value, return to perform the channel selection operation;

[0087] If the current backoff index is less than the preset value, the process returns to the step of determining whether the selected channel has a preamble.

[0088] The backoff wait times refers to the number of times the target device waits and retries after failing to join the selected channel. For example, when the target device selects a channel for the first time and the selected channel has a preamble, the target device backs off and waits. At this time, the backoff wait times is 1. The backoff wait index refers to the index of the backoff wait times.

[0089] The preset number of times and the preset value are pre-set numbers and can be set according to actual conditions, and the embodiments of the present application are not limited thereto.

[0090] In an embodiment of the present application, if a preamble code exists in the selected channel, the target device performs backoff waiting and obtains the backoff waiting times. If the backoff waiting times are equal to the preset times, the target device no longer performs the channel selection operation. If the backoff waiting times are less than the preset times, it is determined whether the current backoff index is equal to the preset value. If the current backoff index is equal to the preset value, it returns to perform the channel selection operation. If the current backoff index is less than the preset value, it returns to execute the determination whether the selected channel has a preamble code, thereby ensuring that the target device can select the channel.

[0091] S102: Based on the target network where the target device is located, the status data is sent to a gateway in the target network, and the gateway is triggered to determine the safety status of the battery based on the status data.

[0092] Among them, the type of the target network can be set according to actual conditions. For example, the target network can be a network built based on long-range radio technology (Long Range Radio, LoRa) or a target network built for LoRaWAN, which is not limited in the embodiments of the present application.

[0093] When the target network is a network built based on long-range radio technology, the target device may be referred to as a long-range radio node device, and the gateway may be referred to as a long-range radio gateway.

[0094] Optionally, the method for the gateway to determine the safety status of the battery based on the status data can be set according to actual conditions. For example, the gateway can perform a subtraction operation on the status data and the preset status data to obtain difference status data. If the difference status data exceeds the preset data, the safety status of the battery is determined to be a normal state, and the normal state indicates that the battery has no safety risks. If the difference status data does not exceed the preset data, the safety status of the battery is determined to be an abnormal state, and the abnormal state indicates that the battery has a safety risk. Alternatively, the gateway can also input the status data into a trained state recognition model for identification to obtain the safety status of the battery. The embodiments of the present application are not limited here.

[0095] In the embodiment of the present application, since the status data can be sent to the gateway through the target network where the target device is located, the battery of the vehicle can be monitored through the status data even if the cellular network of the vehicle is restricted.

[0096] In some embodiments, after the gateway is triggered to determine the safety status of the battery based on the status data, the method further includes:

[0097] Receive prompt information returned by the gateway when the security status is abnormal;

[0098] Perform prompt operations based on prompt information.

[0099] Among them, the prompt information can be set according to the actual situation, for example, the prompt information can be a certain string or a certain graphic, which is not limited in the embodiment of the present application. The type of prompt operation can be set according to the actual situation, for example, the prompt operation can be to send the prompt information to the relevant equipment, and the prompt information can be output to the relevant staff through the relevant equipment, or the prompt operation can control the alarm on the vehicle to sound an alarm, which is not limited in the embodiment of the present application.

[0100] In this embodiment of the present application, since the abnormal state indicates that there is a safety risk in the battery, when the target device receives the prompt information, it can perform a prompt operation based on the prompt information to notify relevant staff that there is a safety risk in the battery, so that the relevant staff can maintain the battery and eliminate the safety risk of the battery.

[0101] In some embodiments, performing a prompt operation based on the prompt information includes:

[0102] Based on the prompt information, the alarm on the vehicle is controlled to sound an alarm to perform a prompt operation.

[0103] Among them, the type of alarm can be set according to actual conditions. For example, the alarm can be a buzzer or a light alarm, which is not limited in the embodiments of the present application.

[0104] In a scenario with many vehicles (for example, a scenario with many vehicles can be a scenario where vehicles are transported by vehicles or vehicles are in a garage), if the prompt information is sent to the relevant device, the relevant device will output the prompt to the relevant staff, and the relevant staff will also need to find the location of the vehicle, which takes a lot of time. In an embodiment of the present application, the target device can control the alarm on the vehicle to sound an alarm based on the prompt information, so that the relevant staff can directly locate the vehicle according to the alarm, thereby improving the efficiency of finding the vehicle, thereby improving the efficiency of eliminating battery safety risks.

[0105] In some embodiments, the present application also includes:

[0106] Determine a processing status of the target device on the status data, where the processing status includes a sending status and / or a collection status;

[0107] If the processing status is a failure status, the first prompt operation is performed.

[0108] Among them, when the processing status is the sending status, if the processing status is the failure status, it means that the status data fails to be sent to the gateway; if the processing status is the success status, it means that the status data is successfully sent to the gateway; when the processing status is the collection status, if the processing status is the failure status, it means that the status data collection fails; if the processing status is the success status, it means that the status data collection is successful. Specifically, when initialization fails, the collection status is determined to be a failure status, or when reading the status data through the information transmission interface fails, the collection status is determined to be a failure status.

[0109] When the processing status is a failure status, it indicates that there is a problem with the battery. At this time, a first prompt operation may be performed so as to prompt relevant manual personnel to eliminate the problem with the battery through the first prompt operation.

[0110] The type of the first prompt operation and the type of the prompt operation may be the same or different, and this embodiment of the present application does not limit this.

[0111] In some embodiments, the alarm may be located on the target device. In this case, the target device may include a connection module, a collection module, a control module, a communication module (the communication module may also be referred to as a transmission module), and an alarm. Figure 2 The target device is connected and powered through the connection module and the information transmission interface, collects status data through the acquisition module, sends the status data to the gateway through the communication module, and controls the alarm through the control module.

[0112] According to the following Figure 3 and Figure 4 , the state determination method provided in the embodiment of the present application is further explained.

[0113] like Figure 3 As shown, when it is detected that the target device is connected to the vehicle through the on-board automatic diagnostic system interface, the vehicle identification code is read and a connection is established with the battery management system. It is determined whether the identification code is read successfully and whether the connection with the battery management system is successful. If the identification code is read successfully and the connection with the battery management system is successful, the target device performs a channel selection operation. It is determined whether there is a preamble code on the selected channel. If not, the target device sends a network access request to the gateway through the selected channel, triggering the gateway to add the target device to the target network based on the network access request. If there is a preamble code, the target device performs a backoff wait and determines whether the backoff wait times are equal to the preset times. If the backoff wait times are equal to the preset times, the target device no longer performs the channel selection operation. If the backoff wait times are less than the preset times, it is determined whether the current backoff index is equal to the preset value. If the current backoff index is equal to the preset value, it returns to perform the channel selection operation. If the current backoff index is less than the preset value, it returns to perform the determination whether there is a preamble code on the selected channel.

[0114] Among them, when the target device no longer performs the channel selection operation, it can be manually disposed of and redeployed, and the target device returns to execute. When it is detected that the target device is connected to the vehicle through the on-board automatic diagnostic system interface, it reads the vehicle's identification code and establishes a connection with the battery management system.

[0115] like Figure 4As shown, the target device establishes a connection with the gateway to determine whether the connection is successful. If the connection is successful, the status data of the vehicle's battery is collected through the on-board automatic diagnostic system interface. Determine whether the collection is successful. If the collection is successful, the status data is sent to the gateway through the target network, and it is determined whether the sending is successful. If the sending is successful, the step of collecting the status data of the vehicle's battery through the on-board automatic diagnostic system interface is returned after a preset time interval. If the sending fails, the alarm is controlled to sound an alarm. If the collection fails, it is determined whether the number of collection failures is equal to the preset number of failures. If the number of collection failures is equal to the preset number of failures, the alarm is controlled to sound an alarm. If the number of collection failures is less than the preset number of failures, the step of collecting the status data of the vehicle's battery through the on-board automatic diagnostic system interface is returned after a preset time interval.

[0116] In an embodiment of the present application, when the target device is connected to the information transmission interface in the vehicle, the status data of the battery of the vehicle is collected through the information transmission interface, and based on the target network where the target device is located, the status data is sent to the gateway in the target network, triggering the gateway to determine the safety status of the battery based on the status data, thereby realizing the collection of battery status data through the target device, and sending the status data to the gateway through the target network, so that the gateway can determine the safety status of the battery based on the status data, so that the safety status of the battery can be monitored even when the vehicle's own cellular network is restricted.

[0117] According to the following Figure 5 , the state determination method provided in this application is explained. Figure 5 A flowchart of a state determination method provided by an exemplary embodiment of the present application is shown. In this embodiment, a gateway is used as an execution subject for explanation, and the target network where the gateway is located includes a target device, and the target device is connected to the information transmission interface in the vehicle. Figure 5 As shown, the state determination method includes the following steps:

[0118] S501. Acquire status data sent by a target device through a target network, where the status data is status data of a battery of a vehicle collected by the target device through an information transmission interface.

[0119] The gateway may include a communication list, which includes a device identifier and / or a communication address of a target device. The target device is polled through the communication list to obtain status data from the target device.

[0120] In some embodiments, before acquiring the status data sent by the target device through the target network, the method further includes:

[0121] Receive the network access request sent by the target device;

[0122] Based on the network access request, the target device is added to the target network where the gateway is located.

[0123] The gateway can also add the target device to the communication list based on the network access request.

[0124] In some embodiments, the target network is a network built based on long-range radio technology, the target device is a long-range radio node device, and the gateway is a long-range radio gateway.

[0125] In some embodiments, the present embodiment further includes:

[0126] If the status data sent by the target device through the target network is not obtained, the status data is obtained from the target device again through the target network;

[0127] If the number of consecutive failures in obtaining the status data meets a preset number condition, the device identification of the target device is sent to the local server, triggering the local server to perform a second prompt operation based on the device identification.

[0128] Among them, the preset number condition can be set according to actual conditions. For example, when the consecutive number is equal to the target number, it is determined that the consecutive number meets the preset number condition. This embodiment does not limit this.

[0129] When the number of consecutive failures in obtaining status data meets a preset number condition, it indicates that an abnormality exists in the target device. At this time, the device identification of the target device may be sent to the local server.

[0130] When the gateway fails to obtain the status data, it starts to count the number of times it fails to obtain the status data, and re-obtains the status data from the target device through the target network.

[0131] The type of the second prompt operation can be set according to actual conditions. For example, the second prompt operation can be to send the device identification of the target device to the relevant device, and the relevant device outputs the device identification to the relevant staff, so that the relevant staff can determine the target device according to the device identification and eliminate the problem of being unable to obtain status data from the target device. The embodiments of the present application are not limited here.

[0132] S502: Determine a safety status of the battery based on the status data.

[0133] Among them, the safety status may include a first safety status and / or a second safety status. The gateway may determine the first safety status of the battery based on the status data, or the gateway may send the status data to a local server so that the local server determines the second safety status of the vehicle's battery based on the status data and the historical status data of the battery.

[0134] Among them, the first safety state and the second safety state are both used to indicate whether there is a safety risk for the battery. The first safety state can indicate whether the battery is at a safety risk in the first dimension, and the second safety state can indicate whether the battery is at a safety risk in the second dimension. The first dimension and the second dimension can be the same or different. For example, the first dimension and the second dimension are both voltages. In this case, the first safety state is a safety state determined according to the voltage in the state data, and the second safety state is a safety state determined according to the voltage in the state data and the voltage in the historical state data. For another example, the first dimension is temperature, and the second dimension is voltage. The first safety state is a safety state determined according to the temperature in the state data, and the second safety state is a safety state determined according to the voltage in the state data and the voltage in the historical state data. The embodiments of the present application are not limited here.

[0135] Optionally, the method for the gateway to determine the first safety state of the battery based on the status data can be set according to actual conditions. For example, the gateway can perform a subtraction operation on the status data and the preset status data to obtain difference status data. If the difference status data exceeds the preset data, the first safety state of the battery is determined to be a normal state, and the normal state indicates that the battery has no safety risk. If the difference status data does not exceed the preset data, the first safety state of the battery is determined to be an abnormal state, and the abnormal state indicates that the battery has a safety risk. Alternatively, the gateway can also input the status data into a trained state recognition model for identification to obtain the first safety state of the battery. The embodiments of the present application are not limited here.

[0136] Optionally, the method for the local server to determine the second safety state of the vehicle's battery based on the status data and the historical status data of the battery can be set according to actual conditions. For example, the local server can perform status analysis on the status data and the historical status data using a preset status analysis algorithm to obtain the second safety state of the battery. The preset status analysis algorithm can be set according to actual conditions. For example, the preset status analysis algorithm can be a trend analysis algorithm or a status analysis neural network model, which is not limited in the embodiments of the present application.

[0137] In an embodiment of the present application, the gateway may also send the status data to the local server. After receiving the status data, the local server may store the status data and immediately determine the second security state based on the stored status data, or, after storing the status data, may also determine the second security state based on the stored status data when the stored status data meets a preset data condition.

[0138] Among them, the preset data condition can be set according to actual conditions. For example, the preset data condition can be that the stored status data satisfies the preset data condition when the increment of the stored status data relative to the status data when the second safety state was last determined is equal to a preset number, or it can be that the stored status data satisfies the preset data condition when the time interval between the current time and the time when the second safety state was last determined is equal to the preset time interval. The embodiments of the present application are not limited here.

[0139] After the local server determines the second security state, if the second security state is an abnormal state, it can send a first prompt message to the gateway, and the gateway then sends the first prompt message to the target device, and the target device then performs a prompt operation based on the first prompt message.

[0140] In an embodiment of the present application, the status data is sent to a local server so that the second safety status of the battery can be determined by the local server.

[0141] In some embodiments, after determining the safety status of the battery based on the status data, the method further includes:

[0142] If the security status is an abnormal state, a prompt message is returned to the target device, triggering the target device to perform a prompt operation based on the prompt message.

[0143] In some embodiments, the prompting operation is controlling an alarm on the vehicle to sound an alarm.

[0144] In some embodiments, the target device may include at least one, the gateway may include multiple communication modules (the communication module may include an acquisition module), a data processing module (the data processing module may also be called a determination module) and a transmission module, and data is exchanged with each target device through each communication module, and the security status of the status data is determined through the data processing module, and the status data is sent to the local server through the transmission module. At this time, the gateway may, for example, Figure 6 shown.

[0145] According to the following Figure 7 , the state determination method provided by this implementation is further explained.

[0146] The gateway establishes a communication list. According to the communication list, the target device is polled. It is determined whether the status data sent by the target device is received. If the status data sent by the target device is received, the safety status of the battery is determined according to the status data, and the format of the status data is converted to obtain the converted status data, and the converted status data is sent to the local server. It is determined whether the safety status is an abnormal state. If it is an abnormal state, a prompt message is sent to the target device, and the target device is triggered to control the alarm based on the prompt message to alarm. If the status data sent by the target device is not received, the status data is obtained from the target device again, and the number of consecutive failures to obtain the status data is counted. It is determined whether the consecutive number meets the preset number condition. If the consecutive number meets the preset number condition, the device identification of the target device is sent to the local server. If the consecutive number does not meet the preset number condition, it indicates that the status data is received, the safety status of the battery is determined according to the status data, and the format of the status data is converted to obtain the converted status data, and the converted status data is sent to the local server.

[0147] In this embodiment, status data sent by the target device through the target network is obtained. The status data is the status data of the vehicle's battery collected by the target device through the information transmission interface. Based on the status data, the safety status of the battery is determined, so that even if the vehicle's cellular network is restricted, the gateway can also obtain the battery status data, thereby monitoring the battery.

[0148] The explanation of terms, other implementation methods and corresponding beneficial effects of this embodiment can be specifically referred to the above-mentioned state determination method embodiment, and this embodiment is not limited here.

[0149] According to the following Figure 8 , the state determination method provided by the present invention is further described. In this embodiment, the local server is used as the execution subject for description.

[0150] 801. Receive status data sent by the gateway. The status data is data sent by the target device to the gateway through the target network. The target device collects the status data through the information transmission interface with the vehicle.

[0151] 802. Determine a safety status of the battery according to the status data.

[0152] The local server may determine the first safety state of the battery based on the state data, or the local server may determine the second safety state of the battery based on the state data and historical state data.

[0153] When the first safety state and / or the second safety state of the battery is an abnormal state, the local server may return a first prompt message to the gateway, the gateway sends the first prompt message to the target device, and the target device performs a prompt operation based on the first prompt message.

[0154] It can be understood that when the first safety state and / or the second safety state is an abnormal state, it indicates that the state data is abnormal. Therefore, the process of determining the safety state of the battery can also be referred to as the process of determining whether the state data is abnormal.

[0155] In some embodiments, when the security status is determined to be a normal status, the local server may also package the status data and send it to the cloud server.

[0156] In some embodiments, when the security status is determined to be an abnormal status, the status data may also be sent to a relevant device so that the relevant device outputs the status data to relevant staff.

[0157] According to the following Fig. 9 , the state determination method provided in this embodiment is further explained.

[0158] The local server receives the status data sent by the gateway, stores the status data and determines the safety status of the battery based on the status data. It determines whether the safety status of the battery is abnormal. If it is abnormal, it sends a first prompt message to the gateway and sends the status data to related devices. If it is normal, it packages the status data and sends it to the cloud server.

[0159] In the present application example, status data sent by the gateway is received. The status data is data sent to the gateway by the target device through the target network. The target device collects the status data through the information transmission interface with the vehicle. Based on the status data, the safety status of the battery is determined, so that the battery can be monitored even if the vehicle's own cellular network is restricted.

[0160] According to the following Fig.10 , further illustrating the state determination method provided by the present application. In this embodiment, the target network is a network constructed based on long-distance radio, the information transmission interface is an on-board automatic diagnostic system interface, and the state determination method can be executed by the state determination system. The state determination system may include at least one target device, a gateway, a local server and a cloud server. At least one target device, a gateway and a local server are all located in the target network, such as Fig.11 The state determination method of this embodiment includes:

[0161] S1001. When the target device detects that it is connected to the on-board automatic diagnostic system interface in the vehicle, it performs a channel selection operation and sends a network access request to the gateway on the selected channel.

[0162] S1002. The gateway adds the target device to the target network based on the network access request, and adds the target device to the communication list.

[0163] S1003. After joining the target network, the target device collects status data of the vehicle's battery through the on-board automatic diagnostic system interface.

[0164] S1004: Based on the communication list, the gateway polls the target device through the target network to obtain status data from the target device.

[0165] S1005: If the gateway obtains the status data, it will determine the first safety state of the battery according to the status data, and send the status data to the local server.

[0166] S1006: If the first security state is an abnormal state, the gateway sends a prompt message to the target device through the target network.

[0167] S1007: The target device performs a prompt operation based on the prompt information.

[0168] S1008. The local server determines a second safety state of the battery according to the state data and historical state data.

[0169] S1009: If the second security state is an abnormal state, the local service sends a first prompt message to the gateway.

[0170] S10010. The gateway sends the first prompt information to the target device, and the target device performs a prompt operation based on the first prompt information.

[0171] S10011. If the second security status is a normal status, the local server uploads the status data to the cloud server.

[0172] S10012. If the gateway fails to obtain the status data, it re-obtains the status data from the target device and determines whether the consecutive number of failures to obtain the status data meets the preset number condition.

[0173] S10013. If the number of consecutive failures in obtaining status data meets a preset number condition, the gateway sends the device identification of the target device to the local server.

[0174] S10014. The local server performs a second prompt operation based on the device identification.
