[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the prior art, a vehicle signal of a single vehicle needs to be judged by each alarm rule, which will lead to the following problems: the more alarm rules there are, the longer the vehicle signal judgment time is. Moreover, as the vehicle signal judgment time increases, the resource occupancy time will increase, and more server resources will be required to complete the signal alarms of a large number of vehicles.

[0040] In view of this, an embodiment of the present invention provides a vehicle signal alarm method, which finds the target alarm rule corresponding to the current signal characteristic information of the vehicle signal from the correspondence between the preset signal characteristic information and the alarm rule, and uses the target alarm rule to issue an alarm. There is no need to compare and judge the vehicle signal with each alarm rule one by one, which greatly shortens the judgment time and reduces server resource costs.

[0041] See also Figure 1 , Figure 1 : is a flow chart of a vehicle signal warning method provided by an embodiment of the present invention, the vehicle signal warning method comprising:

[0042] S1. Obtain vehicle signal;

[0043] S2. generating current signal characteristic information of the vehicle signal;

[0044] S3. Based on the preset correspondence between the signal characteristic information and the alarm rule, obtaining a target alarm rule corresponding to the current signal characteristic information;

[0045] S4. Using the target alarm rule to issue an alarm.

[0046] In the embodiment of the present invention, the correspondence between the signal characteristic information and the alarm rule includes: at least one signal characteristic information, and an alarm rule corresponding to each of the signal characteristic information, and the alarm rule corresponding to one signal characteristic information may include one or more;

[0047] In the embodiment of the present invention, Figure 2 As shown, the Internet of Vehicles cloud platform receives the vehicle signal reported by the vehicle end, generates current signal characteristic information of the vehicle signal, the current signal characteristic information includes description information of one or more signals, compares the current signal characteristic information with the preset signal characteristic information and the signal characteristic information in the corresponding relationship of the alarm rule, obtains the target alarm rule corresponding to the current signal characteristic information, sends the target alarm rule to the vehicle end, and the vehicle end issues an alarm according to the notification method set in the target alarm rule.

[0048] In an optional embodiment, the generating of the current signal characteristic information of the vehicle signal includes:

[0049] A signal belonging to a preset feature library is extracted from the vehicle signal to generate current signal feature information of the vehicle signal; wherein the feature library includes signals in all alarm rules.

[0050] It is understandable that the vehicle signal may include signals that do not require alarms. In this case, if all signals in the vehicle signal are described and current signal characteristic information is generated, this will undoubtedly increase the workload. Therefore, in an embodiment of the present invention, only the signals in the vehicle signal that belong to the alarm rules are described, and current signal characteristic information is generated, which reduces the workload, further reduces the processing time, and speeds up the response.

[0051] In an optional embodiment, the corresponding relationship between the signal characteristic information and the alarm rule is established through the following steps:

[0052] Get all alarm rules;

[0053] Extracting a signal from each of the alarm rules to generate signal feature information for each of the alarm rules;

[0054] The alarm rules of the same signal characteristic information are merged to obtain the corresponding relationship between the signal characteristic information and the alarm rules.

[0055] In an embodiment of the present invention, signal characteristic information is generated based on the signal in the alarm rule, and the corresponding signal characteristic information is obtained through the current signal characteristic information and the target alarm rule is matched. First, all pre-set alarm rules are obtained. Users of different roles can set one or more alarm rules, and each alarm rule includes one or more signal judgment conditions; then, the signal is extracted from each alarm rule and described to generate the signal characteristic information of each alarm rule, wherein the signal characteristic information of each alarm rule includes one or more signal description information, and finally, the alarm rules with the same signal characteristic information are merged to obtain the corresponding relationship between the signal characteristic information and the alarm rule.

[0056] For example, alarm rule 1 is set to give an alarm when signal A>2, alarm rule 2 is set to give an alarm when signal B>3 or signal A>2, and alarm rule 3 is set to give an alarm when signal A>2 and signal C>4. Then the signal characteristic information of alarm rule 1 is signal A>2, and alarm rule 2 has two signal characteristic information, one signal characteristic information is signal B>3, and the other signal characteristic information is signal A>2. The signal characteristic information of alarm rule 3 is signal A>2 and signal C>4. It can be seen that alarm rule 1 and alarm rule 2 have the same signal characteristic information, which is signal A>2.

[0057] At this time, signal A>2 is set as a corresponding relationship with alarm rule 1 and alarm rule 2, signal B>3 is set as a corresponding relationship with alarm rule 2, and signal A>2 and signal C>4 are set as a comparative relationship with alarm rule 3.

[0058] In an optional embodiment, the correspondence between the signal feature information and the alarm rule is stored in a map-like manner.

[0059] It can be understood that the map class is a data structure for storing key-value pairs. The key and value in the map are one-to-one corresponding. It provides an effective way to store and retrieve data, and can quickly find the corresponding value according to the key. In the embodiment of the present invention, the corresponding relationship between the signal feature information and the alarm rule is stored in a map manner to facilitate search and retrieval.

[0060] In an optional embodiment, the acquiring of the vehicle signal comprises one of the following: receiving a vehicle signal periodically reported by the vehicle end;

[0061] Receive vehicle signals reported by the vehicle end based on preset event triggers;

[0062] The receiving vehicle sends a vehicle signal based on the preset instructions.

[0063] In the embodiment of the present invention, the vehicle signal can be obtained in three ways: the vehicle side periodically reports the vehicle signal, the vehicle side event triggers the reporting of the vehicle signal, and the Internet of Vehicles cloud platform sends a command to obtain the vehicle signal.

[0064] In an optional embodiment, the vehicle signal warning method further includes:

[0065] When the target alarm rule corresponding to the current signal characteristic information is not obtained, no alarm is issued.

[0066] In an embodiment of the present invention, when the target warning rule corresponding to the current signal characteristic information is not found from the correspondence between the signal characteristic information and the warning rule, it means that the vehicle signal has no warning rule for the symbol and no warning is needed.

[0067] A vehicle signal alarm method provided by an embodiment of the present invention finds a target alarm rule corresponding to the current signal characteristic information of the vehicle signal from the correspondence between the preset signal characteristic information and the alarm rule, and uses the target alarm rule to issue an alarm. There is no need to compare and judge the vehicle signal with each alarm rule one by one, which greatly shortens the judgment time, enables rapid response, and reduces server resource costs.
