An embodiment of the present invention provides a vehicle data acquisition method, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of the vehicle data acquisition method according to the present invention.
In this embodiment, the vehicle data collection method includes:
step S100, determining a target data acquisition protocol, and acquiring vehicle data based on the target data acquisition protocol;
in this embodiment, it should be noted that the data collection protocol refers to a protocol standard for collecting data on a vehicle. The collection behavior when vehicle data collection is performed may be defined based on the data collection protocol. In this embodiment, vehicle data collection performed by storing data collected from a vehicle end to a cloud end is taken as an example. The vehicle end carries out vehicle data acquisition by predefining a data acquisition protocol and uploads the acquired data to the cloud. The data acquisition protocol is self-defined and can be adaptively adjusted according to actual application and specific values. In a data acquisition protocol, a Controller Area Network (CAN) baud rate, a terminal transmission rate, a vehicle acquisition frequency, a signal item, an association relation between the signal item and a data frame ID and the like are predefined to carry out related limitations of vehicle data acquisition. And acquiring vehicle data based on a predefined data acquisition protocol. The data acquisition protocol is changeable according to practical application, namely before vehicle data acquisition, the data acquisition protocol corresponding to the current vehicle data acquisition behavior needs to be determined, and the protocol is a target data acquisition protocol. Specifically, after the vehicle end determines the target data acquisition protocol, the vehicle end acquires the vehicle data based on the target data acquisition protocol.
Step S200, monitoring whether vehicle abnormal information exists in real time in the vehicle data acquisition process;
in this embodiment, it should be noted that, when vehicle data is collected based on the data collection protocol, if the vehicle is abnormal, the cause of the vehicle abnormality, the position of the vehicle abnormality, and other relevant information need to be determined. For example, when an airbag on a vehicle is exploded, the related information is changed to generate vehicle abnormality information. Whether the abnormal information of the vehicle exists or not is monitored in real time, whether the data acquisition behavior of the vehicle needs to be changed or not is determined in time, and therefore specific analysis is conducted on abnormal occurrence points. Specifically, the cloud analyzes the collected data uploaded by the computer vehicle end in real time to determine whether vehicle abnormal information exists.
And step S300, if yes, determining a change instruction according to the vehicle abnormal information, and continuing to acquire vehicle data based on the change instruction and the target data acquisition protocol.
In this embodiment, the change instruction is an instruction for limiting the vehicle data collection behavior, and is an instruction for changing some limits in the data collection protocol based on the data collection protocol. The vehicle data acquisition behaviors are limited based on the data acquisition protocol, when the vehicle has an emergency, certain limit values in the data acquisition protocol can be temporarily changed through the change instruction, the vehicle data acquisition behaviors are temporarily limited through the change instruction, and the data acquisition behaviors under the emergency of the vehicle are pertinently adjusted. For example, when vehicle abnormal information occurs, the transmission rate of the terminal is changed by changing the instruction, the vehicle acquisition frequency is increased, and the number of signal items is increased, so that more vehicle data can be acquired within a certain time, and the vehicle abnormal information can be accurately analyzed. Specifically, if vehicle abnormal information is monitored, a change instruction is determined for the vehicle abnormal information, and a target data acquisition protocol is changed based on the change instruction, so that vehicle data acquisition is continued based on the changed data acquisition protocol after the vehicle abnormal information is monitored.
In the embodiment of the invention, a target data acquisition protocol is determined to obtain a behavior standard for vehicle data acquisition, and then vehicle data acquisition is carried out based on the target data acquisition protocol to obtain vehicle data; whether abnormal information of the vehicle exists or not is monitored in real time in the vehicle data acquisition process, whether the vehicle is abnormal or not is determined, when the vehicle is determined to be abnormal, a change instruction is determined according to the abnormal information of the vehicle, emergency situations can be flexibly dealt with through the change instruction, the flexibility of data acquisition is improved, vehicle data acquisition is carried out based on the change instruction and a target data acquisition protocol, omission of effective data under the abnormal condition of the vehicle is avoided, vehicle data acquisition is effectively carried out, data analysis basis is provided for abnormal behaviors, and the fact that functional services are normal when the vehicle operates is ensured.
Further, based on the first embodiment of the vehicle data acquisition method of the present invention, a second embodiment of the vehicle data acquisition method of the present invention is provided, where in the step S100, a target data acquisition protocol is determined, and the step of acquiring the vehicle data based on the target data acquisition protocol includes:
step a, acquiring time information and version information of a current data acquisition protocol of a vehicle;
b, monitoring whether the current data acquisition protocol has a corresponding acquisition protocol upgrading version according to the time information and the version information;
and c, if the acquisition protocol upgrading version exists, taking the acquisition protocol upgrading version as a target data acquisition protocol, and acquiring vehicle data based on the target data acquisition protocol.
In this embodiment, it should be noted that the data acquisition protocol is defined before vehicle data acquisition, and the data acquisition protocol is customized by an administrator, and may be adaptively adjusted according to a specific value in actual application to upgrade the version of the data acquisition protocol. Before vehicle data acquisition is carried out, whether a corresponding data acquisition protocol upgrading version exists in the current vehicle data acquisition behavior or not needs to be determined, if the data acquisition protocol upgrading version exists, the version upgrading of the data acquisition protocol needs to be carried out, and vehicle data acquisition is carried out based on the data acquisition protocol after the version upgrading. The acquisition protocol upgrade version refers to a data acquisition protocol in which some values in the data acquisition protocol are changed according to actual requirements. For example, when the signal item in the current data acquisition protocol is 50, according to the actual requirement, the administrator changes the signal item in the data acquisition protocol to 100, and generates a new data acquisition protocol, that is, an updated version of the acquisition protocol. The data acquisition protocol carries the time and version number generated by the data acquisition protocol.
Specifically, before data acquisition, the vehicle end sends a data acquisition protocol request to the cloud acquisition module, the cloud acquisition module forwards the data acquisition protocol request to the management control module, and the management control module acquires time information and version information in a currently downloaded data acquisition protocol of the vehicle end through the data acquisition protocol request to determine generation time and version number of the downloaded data acquisition protocol. And determining whether there is an acquisition protocol upgrade version closer to the current time than the generation time of the downloaded data acquisition protocol and/or an acquisition protocol upgrade version having a higher version number than the version number of the downloaded data acquisition protocol, according to the time information and the version information. If the target data collection protocol exists, the cloud management control module takes the updated collection protocol version as the target data collection protocol and returns the updated collection protocol version to the collection module, the collection module forwards the target data protocol to the vehicle end, the vehicle end downloads the returned target data collection protocol, and vehicle data collection is carried out based on the target data collection protocol. And if not, taking the original downloaded data acquisition protocol as a target data acquisition protocol.
In the embodiment, the latest data acquisition protocol is acquired by downloading the upgrade version of the acquisition protocol to acquire the vehicle data, so that the actual application requirements are met, and the applicability of the data acquisition protocol is improved.
Further, the step of continuing vehicle data collection based on the change instruction and the target data collection protocol includes:
d, changing the transmission rate, the acquisition frequency and the signal item preset in the target data acquisition protocol according to the change instruction;
and e, continuing to acquire the vehicle data based on the changed target data acquisition protocol.
In this embodiment, it should be noted that, when an emergency occurs in a vehicle, some limit values in a target data collection protocol in the vehicle may be temporarily changed through a change instruction, a vehicle data collection behavior is temporarily limited through the change instruction, and a data collection behavior in the vehicle emergency is specifically adjusted. The change instruction is an instruction issued only aiming at the current emergency, and after the sudden abnormality of the vehicle is determined to be finished, the target data acquisition protocol before the change instruction is recovered continues to acquire the vehicle data. The change instruction can comprise a transmission rate change instruction, a collection frequency change instruction and a signal item change instruction, the transmission rate, the collection frequency and the signal item limited in the target data collection protocol are changed through the change instruction to obtain a changed target data collection protocol, and vehicle data collection is carried out through the changed target data collection protocol after vehicle abnormal information is monitored. For example, the storage calculation module corresponding to the cloud calculates and analyzes to obtain the abnormality of the vehicle airbag explosion, and obtains more vehicle information in the same time by changing the transmission rate, increasing the vehicle data acquisition frequency and increasing the vehicle data acquisition signal item.
The vehicle data acquisition method flexibly deals with vehicle emergencies through the change instruction, vehicle data acquisition is carried out aiming at the emergencies, and after the abnormity is determined to be finished, the target data acquisition protocol before change is recovered to continue acquisition, so that system resources are saved, performance requirements are lowered, and the applicability of the data acquisition protocol is improved.
Further, before the step of determining the target data acquisition protocol, the method further comprises:
step f, vehicle information is obtained;
step g, judging whether the vehicle information is matched with preset vehicle information in a preset database;
and h, if the vehicle information is matched with the preset vehicle information, executing a step of determining a target data acquisition protocol.
In this embodiment, it should be noted that before vehicle data acquisition, the cloud end needs to determine whether the current vehicle is a legal device, and the identity of the vehicle is verified through vehicle information to determine whether the vehicle is legal. The preset vehicle information refers to the relevant information of the legal vehicle stored in the preset database, for example, the vehicle relevant information such as the terminal barcode and the terminal number. And finally, verifying the identity of the vehicle if the relevant information corresponding to the verified vehicle is matched with the preset vehicle information. Specifically, when an acquisition module corresponding to the cloud end is connected with a vehicle end, vehicle information corresponding to the vehicle end is acquired, the acquisition module forwards the vehicle information to a management control module for vehicle identity verification, the management control module compares the vehicle information with preset vehicle information in a preset database, and if the comparison is passed, the vehicle information is considered to be matched with the preset vehicle information, and the authentication is passed; if the comparison fails, the vehicle information is not matched with the preset vehicle information, and the authentication fails. The management control module returns an authentication result to the acquisition module, the acquisition module forwards the authentication result to the vehicle end, and after the vehicle end receives the authentication result, if the vehicle end determines that the authentication is passed, the vehicle end requests the acquisition module at the cloud end for a data acquisition protocol. If the authentication is not passed, the vehicle will not be able to request a data collection protocol.
In the embodiment, the legality of the identity of the vehicle is verified, so that the vehicle data acquisition object is ensured to be a legal terminal, and the data acquisition safety is improved.
Further, before the step of obtaining the vehicle information, the method further includes:
step i, acquiring a cluster domain name resolution request sent by a vehicle;
step j, performing domain name resolution according to the cluster domain name resolution request, and returning a domain name resolution result;
and k, executing the step of acquiring the vehicle information based on the domain name resolution result.
In this embodiment, it should be noted that the cloud includes a plurality of clusters, and the cluster for data storage after data acquisition needs to be determined when vehicle data acquisition is performed. The cluster domain name resolution request comprises a cluster domain name request, the cloud domain name resolution module can perform domain name resolution through the cluster domain name to obtain a cluster IP, and the vehicle end can determine a corresponding data storage cluster according to the cluster IP. Specifically, the vehicle end sends a cluster domain name resolution request to the cloud end, and a domain name resolution module of the cloud end performs domain name resolution on the cluster domain name in the cluster domain name resolution request to obtain a cluster IP and returns the cluster IP to the vehicle end.
In the embodiment, the data storage cluster is determined through the cluster domain name resolution request, so that the effective management of vehicle data is realized, the data storage position is determined in advance, and the data acquisition efficiency is improved.
Referring to fig. 3, in fig. 3, the car end sends a cluster domain name resolution request to the cloud domain name resolution module, and the cloud domain name resolution module performs domain name resolution on the cluster domain name in the cluster domain name resolution request to obtain a cluster IP, and returns the cluster IP to the car end. The vehicle end carries vehicle information and is connected with an acquisition module of the cloud end, the acquisition module forwards the vehicle information to the management control module for vehicle identity verification, the management control module returns an authentication result to the acquisition module, and the acquisition module forwards the authentication result to the vehicle end. After the vehicle end passes the identity verification, a data acquisition protocol request is sent to the acquisition end of the cloud end, the acquisition module of the cloud end forwards the data acquisition protocol request to the management control module, the management control module returns a target data acquisition protocol to the acquisition module, and the acquisition module forwards the target data protocol to the vehicle end. The vehicle end collects data based on a target data forwarding protocol, encrypts the collected data and uploads the encrypted data to the collection module at the cloud end, the collection module forwards the encrypted collected data to the storage and calculation module, the storage and calculation module performs real-time calculation and storage, early warning is triggered when abnormal information of a vehicle is detected, a change instruction is sent to the collection end, and the collection end forwards the change instruction to the vehicle end. So that the vehicle data acquisition is carried out by the vehicle end based on the change instruction and the target data acquisition protocol.
Further, the step of monitoring whether the vehicle abnormal information exists in real time in the vehicle data acquisition process comprises the following steps:
step l, acquiring the acquired data which is encrypted and uploaded after vehicle data acquisition is carried out in real time;
and m, determining whether the vehicle abnormal information exists according to whether the acquired data is abnormal.
In this embodiment, it should be noted that, after the vehicle data is collected, the vehicle end encrypts the collected data, and uploads the encrypted collected data to the cloud end. The collected data further comprises vehicle state information, the vehicle end collects the data and then uploads the data to a collection module corresponding to the cloud end, the collection module in the cloud end forwards the collected data to a storage calculation module in the cloud end, the storage calculation module judges whether the vehicle is abnormal at present according to the vehicle state information in the collected data, and if the vehicle is determined to be abnormal, the vehicle abnormal information is considered to exist in the collected data. And if the abnormality does not exist, the current vehicle is considered to be normal in operation. When abnormal information of the vehicle is monitored, the storage and calculation module triggers early warning and sends a change instruction.
In this embodiment, it should be noted that whether vehicle abnormal information exists in the collected data is monitored in real time, the vehicle running state is judged in real time, the abnormality is timely handled, and normal running of the functional service of vehicle running is ensured.

step o, determining a data storage server from each storage server based on the data volume and the storage capacity;
and step p, storing the acquired data into the data storage server.
In this embodiment, it should be noted that, after acquiring the collected data uploaded by the vehicle end, the cloud end needs to store the collected data, and the servers for storing the collected data are not limited to the same server, so that distributed storage of the collected data is realized, and storage resources of the servers are reasonably utilized. The data volume corresponding to the acquired data is the volume of the acquired data written in when the cloud acquires the acquired data. The storage capacity refers to a capacity for storing the collected data corresponding to a server for storing the collected data in the cluster. The data storage server is a server which is determined by the cloud for storing the acquired data after judgment. Specifically, after acquiring the acquired data of the vehicle data, determining the data volume corresponding to the acquired data, acquiring the current storage capacity of all servers capable of storing the data, and performing data distribution storage based on the current data volume and the storage capacity of the servers, so that the load of each storage server tends to be balanced as much as possible. Specifically, a data volume corresponding to the acquired data and a storage capacity corresponding to the storage server are acquired, the data storage server is determined based on the data volume and the storage capacity, the acquired data is stored in the data storage server, and the data is balanced in each storage server. It can be understood that the number of the data storage servers for storing the collected data may be one or more, and when the number of the data storage servers is multiple, the same batch of collected data stored in different data storage servers is identified by data identification such as pointers, so as to implement association before the collected data.
In this embodiment, the collected data is automatically stored in a balanced manner according to the load condition of the server, so that the data is hashed in the cluster, the cluster performance is fully utilized, storage capacity expansion is relatively performed, and the data storage capacity is improved.
