[0062] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] Example 1

[0064] This application provides a method for early warning of abnormal vehicle communication, applied to a vehicle terminal, as described above. Figure 1 In the first embodiment of the vehicle communication anomaly early warning method of this application, the vehicle communication anomaly early warning method includes:

[0065] Step S10: Detect whether a long connection has been broken between the vehicle terminal and the first cloud server. If a long connection has been broken, detect the network signal strength of the area where the vehicle terminal is located.

[0066] Step S20: Based on the network signal strength, detect the cause of the communication failure between the vehicle terminal and the first cloud server;

[0067] Step S30: Based on the cause of the communication failure, push the corresponding communication anomaly warning information.

[0068] As an example, steps S10 to S30 include: detecting whether a heartbeat loss has occurred between the vehicle terminal and the first cloud server; if no heartbeat loss has occurred, it is determined that no long-term connection has been broken between the vehicle terminal and the first cloud server; if a heartbeat loss has occurred, it is determined that a long-term connection has been broken between the vehicle terminal and the first cloud server; detecting the network signal strength in the area where the vehicle terminal is located; based on the network signal strength, detecting whether the communication failure between the vehicle terminal and the first cloud server is due to poor network signal; if so, pushing a communication anomaly warning message indicating poor network signal to the user through the display interface of the vehicle terminal; if not, detecting whether the communication failure is due to a damaged communication module or an abnormality of the first cloud server through the second cloud server, and pushing the corresponding communication anomaly warning message to the user through the display interface of the vehicle terminal. The display interface of the vehicle terminal can be a display screen or instrument panel, for example, the communication status on the instrument panel can be changed to "not connected".

[0069] The step of detecting the cause of communication failure between the vehicle terminal and the first cloud server based on the network signal strength includes:

[0070] Step S21: If the network signal strength is greater than the first preset signal strength threshold, the cause of the communication failure between the vehicle terminal and the first cloud server is detected through the second cloud server.

[0071] Step S22: If the network signal strength is not greater than the first preset signal strength threshold, then the cause of the communication failure is determined to be poor network signal in the area where the vehicle terminal is located.

[0072] As an example, steps S21 to S22 include: if the network signal strength is greater than a first preset signal strength threshold, it is determined that the network signal in the area where the vehicle terminal is located is poor, and then the second cloud server is used to detect whether the communication failure between the vehicle terminal and the first cloud server is caused by a damaged communication module or an abnormality of the first cloud server.

[0073] The communication anomaly warning information includes a first warning information, a second warning information, and a third warning information. The step of pushing the corresponding communication anomaly warning information according to the cause of the communication failure includes:

[0074] Step S31: If the communication failure is caused by damage to the communication module of the vehicle terminal, then the corresponding first warning information is pushed through the display module of the vehicle terminal.

[0075] Step S32: If the communication failure is caused by an abnormality in the first cloud server, then the corresponding second warning information is pushed through the display module of the vehicle terminal.

[0076] Step S33: If the communication failure is caused by poor network signal, then the corresponding third warning information is pushed through the display module of the vehicle terminal.

[0077] In this embodiment, it should be noted that after determining the cause of the communication failure, the corresponding warning information can be pushed through the display module of the vehicle terminal to notify the user that a communication failure has occurred between the vehicle terminal and the first cloud server. The first warning information is used to indicate that the communication module of the vehicle terminal is damaged, the second warning information is used to indicate that the first cloud server is abnormal, and the third warning information is used to indicate that the network signal is poor.

[0078] This application provides a method for early warning of in-vehicle communication anomalies. It detects whether a long-term connection between the in-vehicle terminal and a first cloud server has been broken. If a long-term connection is broken, it detects the network signal strength in the area where the in-vehicle terminal is located. Based on the network signal strength, it detects the cause of the communication failure between the in-vehicle terminal and the first cloud server. Based on the cause of the communication failure, it pushes corresponding communication anomaly warning information. This application, by establishing a long-term connection between the in-vehicle terminal and the cloud server, can detect in real time whether the communication between the in-vehicle terminal and the first cloud server is broken. Therefore, after a long-term connection break is detected, the cause of the communication failure between the in-vehicle terminal and the first cloud server can be detected based on the network signal strength. Based on the cause of the communication failure, corresponding communication anomaly warning information is pushed, allowing the user to perceive that the in-vehicle communication has failed and the reason for the failure.

[0079] Example 2

[0080] Reference Figure 2 Based on the first embodiment of this application, in another embodiment of this application, the step of detecting the cause of communication failure between the vehicle terminal and the first cloud server via the second cloud server includes:

[0081] Step A10: Obtain the first key-value information that the first cloud server regularly maintains from the second cloud server;

[0082] Step A20: If the acquisition fails, the communication failure is determined to be caused by damage to the communication module of the vehicle terminal.

[0083] Step A30: If successful, then based on the first key value information, detect the cause of the communication failure between the vehicle terminal and the first cloud server.

[0084] In this embodiment, it should be noted that the second cloud server is used to deploy a preset key-value database, which can be Redis. Both the vehicle terminal and the first cloud server can periodically maintain their respective key-value information in the preset key-value database.

[0085] As an example, steps A10 to A30 include: obtaining first key-value information that the first cloud server regularly maintains from the second cloud server; if the acquisition fails, it proves that the vehicle terminal cannot communicate with either the first cloud server or the second cloud server, thereby determining that the communication failure is caused by damage to the communication module of the vehicle terminal; if the acquisition is successful, it is determined, based on the first key-value information, whether the communication failure between the vehicle terminal and the first cloud server is caused by an abnormality of the first cloud server.

[0086] The first key-value information includes a server status identifier and a first timestamp.

[0087] The step of detecting the cause of communication failure between the vehicle terminal and the first cloud server based on the first key value information includes:

[0088] Step A31: If the server status identifier is the first preset identifier, then the cause of the communication failure is determined to be an anomaly in the first cloud server.

[0089] Step A32: If the server status identifier is the second preset identifier, then the cause of the communication failure between the vehicle terminal and the first cloud server is detected based on the first timestamp.

[0090] In this embodiment, it should be noted that the preset identifier is used to identify the status of the cloud server. For example, when the first preset identifier is set to 1, the status of the cloud server is identified as normal, and when the second preset identifier is set to 0, the status of the cloud server is identified as abnormal.

[0091] As an example, steps A31 to A32 include: if the server status identifier is a first preset identifier, then the cause of the communication failure is determined to be an anomaly of the first cloud server; if the server status identifier is a second preset identifier, then the cause of the communication failure between the vehicle terminal and the first cloud server is detected according to the time interval between the first timestamp and the current time.

[0092] The step of detecting the cause of the communication failure between the vehicle terminal and the first cloud server based on the first timestamp includes:

[0093] Step A321: Obtain the time interval between the first timestamp and the current time;

[0094] Step A322: If the time interval is greater than a preset time interval threshold, the communication failure is determined to be caused by an anomaly in the first cloud server.

[0095] As an example, steps A321 to A322 include: calculating the difference between the current time and the first timestamp to obtain a time interval; if the time interval is greater than a preset time interval threshold, it proves that the first cloud server did not update the first key-value information on the second cloud server on time, thereby determining that the communication failure is caused by an anomaly in the first cloud server; if the time interval is not greater than the preset time interval threshold, it proves that the first cloud server is still updating the first key-value information on the second cloud server on time, thereby determining that the first cloud server has not experienced an anomaly.

[0096] The vehicle communication anomaly early warning method further includes:

[0097] Step B10: Periodically maintain the second key-value information of the second cloud server, wherein the second key-value information includes vehicle status information and a corresponding second timestamp, so that the first cloud server can determine the vehicle status of the vehicle terminal by obtaining the second key-value information from the second cloud server.

[0098] In this embodiment, it should be noted that the second key value information can be vehicle status information and a second timestamp, wherein the vehicle status information can be an expired key value, and the second timestamp can be the timestamp when the expired key value was written.

[0099] As an example, step B10 includes: writing vehicle status information as expired key values ​​into the preset key value database, and periodically updating the vehicle status information in the preset key value database, wherein the update interval of the vehicle status information is less than the expiration interval of the vehicle status information, so as to ensure that the vehicle status information is not deleted from the preset key value database due to expiration. Thus, the first cloud server obtains the second key value information from the second cloud server to determine whether the vehicle terminal is continuously updating the vehicle status information and the time of the last update of the vehicle status information. Therefore, after the first cloud server disconnects from the vehicle terminal, the first cloud server can further determine the vehicle status corresponding to the vehicle terminal by checking the preset key value database.

[0100] This application provides a method for early warning of communication anomalies in vehicles. After determining that the cause of the communication failure between a first cloud server and a vehicle terminal is not poor network signal, the method retrieves first key-value information, which is periodically maintained by the first cloud server, from a second cloud server. If retrieval fails, the method determines that the communication failure is caused by damage to the communication module of the vehicle terminal. If retrieval is successful, the method detects the cause of the communication failure between the vehicle terminal and the first cloud server based on the first key-value information. This method achieves the goal of confirming the cause of the communication failure by using a second cloud server, and can further identify whether the communication failure is caused by an anomaly in the first cloud server or by damage to the communication module of the vehicle terminal. It can further pinpoint the cause of the communication failure between the vehicle terminal and the first cloud server, thus improving the accuracy of locating the cause of vehicle communication failures.

[0104] The second detection module 200 is used to detect the cause of the communication failure between the vehicle terminal and the first cloud server based on the network signal strength.

[0105] The fault cause push module 300 is used to push corresponding communication anomaly warning information based on the cause of the communication fault.

[0106] Optionally, the second detection module 200 is further configured to:

[0107] If the network signal strength is greater than the first preset signal strength threshold, the cause of the communication failure between the vehicle terminal and the first cloud server is detected through the second cloud server.

[0108] If the network signal strength is not greater than the first preset signal strength threshold, the communication failure is determined to be caused by poor network signal in the area where the vehicle terminal is located.
