Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a method for processing internet of vehicles data according to an exemplary embodiment, as shown in fig. 1, the method including:
For example, an application scenario related to each embodiment in the present disclosure is first described, where the application scenario may be that a car networking platform processes a car networking data packet uploaded by a vehicle, that is, an execution subject of this embodiment may be understood as a car networking platform. The vehicle can be according to the cycle of predetermineeing constantly uploading the car networking data package to the car networking platform, and the car networking platform can divide the car networking data package that receives according to the time quantum of predetermineeing, then handles to the first quantity group car networking data package that receives in the time quantum of predetermineeing. The preset time period may be, for example, one month or 10 days. Because every group's car networking data package is that the vehicle uploads in proper order, it is corresponding, first quantity group's car networking data package also arranges according to the transmission time sequence that corresponds in the car networking platform, and wherein transmission time can include the time that the vehicle uploaded the car networking data package, also can include the time that the car networking platform received the car networking data package. Specifically, the vehicle networking data packet may include a second number of operation data, and may also include a collection time corresponding to each operation data, where the collection time is used to represent a time when the vehicle collects the operation data. The operation data CAN reflect an operation state of the vehicle, and may include, for example, positioning data such as longitude and latitude of the vehicle, CAN (Controller Area Network, chinese) bus data such as mileage data, fuel consumption data, vehicle speed data, vehicle acceleration data, engine speed data, torque data, and the like of the vehicle.
And 102, comparing the group of the Internet of vehicles data packets with the previous group of the Internet of vehicles data packets according to each group of the Internet of vehicles data packets, and processing the group of the Internet of vehicles data packets according to the comparison result.
For example, each set of the internet of vehicles data packets may include two types of data, the first type is positioning data, the second type is CAN bus data, and the column name corresponding to the positioning data may be preceded by "L _" as a start, and the column name corresponding to the CAN bus data may be preceded by "C _" as a start, so as to distinguish the two types of data. Thereafter, the two types of data can be processed according to the format of Key-Value. Specifically, for each group of the car networking data packets, the group of the car networking data packets may be compared with the previous group of the car networking data packets, and the group of the car networking data packets may be processed according to the comparison result. The last group of the car networking data packets may be understood as a group of car networking data packets that are sequentially before the group of car networking data packets in the first number of the group of car networking data packets.
Specifically, under normal conditions, the operating state of the vehicle is stably changed along with time, and the situation of numerical value mutation does not occur, so that the internet-of-vehicles data packet uploaded within a period of time often includes many repeated operating data. Thus, each operational data included in the set of Internet of vehicles data packets may be compared to each operational data included in the previous set of Internet of vehicles data packets and a determination may be made whether to retain such operational data based on whether the comparison is the same. In one implementation, if a Value (i.e., Value) of one type of operation data included in the set of the car networking data packets is the same as a Value of one type of operation data included in a previous set of the car networking data packets, the type of operation data included in the set of the car networking data packets may be deleted, and meanwhile, a collection time corresponding to the type of operation data included in the set of the car networking data packets is reserved. If the value of one kind of operation data included in this group of car networking data package is different with the value of this kind of operation data included in last group of car networking data package, then keep this kind of operation data and the corresponding acquisition time that include in this group of car networking data package. In another implementation, if the Value (i.e., Value) of one kind of operation data included in the set of the car networking data packets is the same as the Value of the kind of operation data included in the previous set of the car networking data packets, the kind of operation data included in the previous set of the car networking data packets may be deleted and the kind of operation data included in the set of the car networking data packets may be retained. If the value of one kind of operation data included in the group of internet of vehicles data packets is different from the value of the kind of operation data included in the last group of internet of vehicles data packets, the kind of operation data included in the last group of internet of vehicles data packets and the kind of operation data included in the group of internet of vehicles data packets are reserved.
Taking mileage data as an example, mileage data in the set of internet-of-vehicles data packets and mileage data in a previous set of internet-of-vehicles data packets can be compared, if the mileage data in the set of internet-of-vehicles data packets is different from the mileage data in the previous set of internet-of-vehicles data packets, the mileage data in the set of internet-of-vehicles data packets is retained, if the mileage data in the set of internet-of-vehicles data packets is the same as the mileage data in the previous set of internet-of-vehicles data packets, mileage data in the set of internet-of-vehicles data packets is deleted, and only acquisition time corresponding to the mileage data in the set of internet-of-vehicles data packets is retained.
And 103, storing each kind of operation data in the set of processed vehicle networking data packets, and storing the acquisition time corresponding to the kind of operation data and the time difference of the acquisition time corresponding to the kind of operation data in the previous set of vehicle networking data packets.
For example, different storage methods are adopted to store each kind of operation data in the car networking data packet processed in step 102 and the corresponding acquisition time of the kind of operation data. Specifically, the operation data may be directly stored, for example, by using a byte storage method. For the acquisition time corresponding to each kind of data, the acquisition time corresponding to the kind of operation data and the time difference between the acquisition time corresponding to the kind of operation data in the last group of internet-of-vehicles data packets can be stored. For example, when the collection time of the mileage data in the set of internet-of-vehicles data packets is stored, the collection time of the mileage data in the set of internet-of-vehicles data packets may be different from the collection time of the mileage data in the previous set of internet-of-vehicles data packets to obtain a time difference of the collection time, and then the time difference is stored as the collection time corresponding to the mileage data in the set of internet-of-vehicles data packets.
And 104, dividing and storing the transmission time corresponding to the first quantity of vehicle networking data packets into a third quantity of transmission time groups according to a preset time interval, wherein each transmission time group comprises a plurality of transmission times which are sequentially arranged.
For example, the transmission time corresponding to the vehicle networking data packets may include the uploading time of the vehicle networking data packets uploaded by the vehicle and the receiving time of the vehicle networking data packets received by the vehicle networking platform, the transmission time corresponding to each group of vehicle networking data packets in the first number of groups of vehicle networking data packets may be divided and stored as a third number of transmission time groups according to a preset time interval, and the preset time interval may be 1 day. For example, the preset time period is 30 days, the time interval is 1 day, 10000 (i.e., the first number) groups of the internet-of-vehicle data packets are uploaded within 30 days, and correspond to 10000 transmission times, then 10000 transmission times can be divided into 30 transmission time groups for storage, and each transmission time group includes transmission time corresponding to the internet-of-vehicle data packets uploaded within 1 day. Specifically, when the transmission time corresponding to a group of internet of vehicles data packets is stored, the transmission time of the group of internet of vehicles data packets may be differed from zero minutes and zero seconds of the time of the day, so as to obtain the time difference of the transmission time, and then the time difference of the transmission time is stored as the transmission time of the group of internet of vehicles data packets. The transmission time of a group of vehicle networking data packets can also be differed from the last transmission time in the same transmission time group to obtain the time difference of the transmission time, and then the time difference of the transmission time is stored as the transmission time of the group of vehicle networking data packets. It should be noted that the acquisition time corresponding to each kind of operation data represents the time for the vehicle to acquire the kind of operation data, that is, a group of vehicle networking data packets includes the second amount of acquisition time corresponding to the second amount of operation data, the amount of acquisition time is large, and the occupied space is large, so that the acquisition time corresponding to each kind of operation data can be subjected to difference processing and stored according to step 103. The transmission time represents the transmission time of the car networking data packets, that is, one group of car networking data packets corresponds to one uploading time and one receiving time, the first number of car networking data packets corresponds to the first number of uploading time and receiving time, the number of the transmission time is small, and the occupied space is small, so that the transmission time can be grouped and stored according to the step 104.
Like this, the acquisition time in the car networking data package is stored according to the time difference, can effectively reduce the shared storage space of acquisition time, and the shared storage space of transmission time can effectively be reduced to the transmission time packet storage that the car networking data package corresponds simultaneously to realized that car networking data is harmless, compress fast, effectively reduce the storage space that car networking data occupy.
In summary, a plurality of sets of internet-of-vehicles data packets uploaded by vehicles within a preset time period are received. And then, aiming at each group of the Internet of vehicles data packets, comparing the group of the Internet of vehicles data packets with the last group of the Internet of vehicles data packets, and processing the group of the Internet of vehicles data packets according to the comparison result. And then, storing each kind of operation data in the set of processed vehicle networking data packets, and storing the acquisition time corresponding to the kind of operation data and the time difference of the acquisition time corresponding to the kind of operation data in the previous set of vehicle networking data packets. And finally, dividing and storing the transmission time corresponding to the multiple groups of Internet of vehicles data packets into multiple transmission time groups according to a preset time interval. This openly stores the acquisition time in the car networking data package according to the time difference to carry out the packet storage with the transmission time that the car networking data package corresponds, can realize that car networking data is harmless, compress fast, effectively reduce the storage space that car networking data occupy.
FIG. 2 is a flow chart illustrating another method of processing Internet of vehicles data in accordance with an exemplary embodiment. As shown in fig. 2, step 102 may include the steps of:
And 1022, reserving acquisition time corresponding to each operation data in the set of Internet of vehicles data packets.
For example, if the value of one type of operation data included in a set of the car networking data packets is the same as the value of one type of operation data included in the previous set of the car networking data packets, the type of operation data included in the set of the car networking data packets may be deleted, while the collection time corresponding to the type of operation data included in the set of the car networking data packets is reserved. Taking mileage data as an example, mileage data in a group of internet-of-vehicles data packets can be compared with mileage data in a previous group of internet-of-vehicles data packets, and if the mileage data in the group of internet-of-vehicles data packets is the same as the mileage data in the previous group of internet-of-vehicles data packets, the mileage data in the group of internet-of-vehicles data packets is deleted, and only acquisition time corresponding to the mileage data in the group of internet-of-vehicles data packets is reserved. After the processing is carried out on each kind of operation data in the Internet of vehicles data packet, a large amount of repeated data in the Internet of vehicles data packet can be deleted, the data volume in the processed Internet of vehicles data packet can be effectively reduced, and therefore the corresponding storage space is saved.
FIG. 3 is a flow chart illustrating another method of processing Internet of vehicles data in accordance with an exemplary embodiment. As shown in fig. 3, step 102 may further include the steps of:
For example, after receiving a first number of sets of internet-of-vehicles data packets uploaded by vehicles within a preset time period, the operation data meeting the filtering rule in each set of internet-of-vehicles data packets may be deleted. Wherein the filtering rules may include: invalid operational data, and/or operational data having a null value. Can be in advance to every kind of operation data, set up effective numerical range, when carrying out step 1023, can compare every kind of operation data's that a set of car networking data package includes numerical value with the effective numerical range that corresponds, if this kind of operation data's numerical value belongs to the effective numerical range that corresponds, then unsatisfied filtering rule, keep this kind of operation data, if this kind of operation data's numerical value, do not belong to the effective numerical range that corresponds, then confirm that this kind of operation data is invalid, satisfy filtering rule, delete this kind of operation data. And filtering the operation data in the Internet of vehicles data packet according to the filtering rule, deleting invalid operation data or operation data with empty operation data, and further reducing the data amount in the processed Internet of vehicles data packet, thereby saving corresponding storage space.
FIG. 4 is a flow chart illustrating another method of processing Internet of vehicles data in accordance with an exemplary embodiment. As shown in fig. 4, after step 102, the method further comprises the steps of:
and 105, determining the size of the target space according to the length and the quantity of each kind of operation data in each group of processed Internet of vehicles data packets and the length of acquisition time corresponding to each kind of operation data.
And step 106, applying for a corresponding target memory space according to the size of the target space.
For example, before storing the processed internet of vehicles data packets, the size of the target space required for storing the processed internet of vehicles data packets may be determined according to the length and the number of each kind of operation data in each group of processed internet of vehicles data packets and the length of the acquisition time corresponding to each kind of operation data. Specifically, the length of each kind of operation data may be determined first, and then the number of each kind of operation data in all the processed car networking data packets may be counted. The length of each kind of operation data is multiplied by the number of the kind of operation data, and then the first space size required for storing the kind of operation data can be obtained. The length of each kind of operation data can be understood as the number of bytes occupied when the operation data is stored. Furthermore, the length of the acquisition time corresponding to each kind of operation data may be determined, and then the length of the acquisition time corresponding to the kind of operation data is multiplied by the first number, so that the size of the second space required for storing all the acquisition times can be obtained. The length of the acquisition time can be understood as the number of bytes occupied by storing the acquisition time.
Thereafter, a target spatial size may be determined based on the first spatial size and the second spatial size. For example, the target space size = (the first space size + the second space size) × N, where N is a preset coefficient, which may be 3, for example. And finally, applying for a corresponding target memory space according to the size of the target space.
FIG. 5 is a flow chart illustrating another method of processing Internet of vehicles data in accordance with an exemplary embodiment. As shown in fig. 5, step 103 may include the steps of:
In an example, different storage modes are adopted for storing each kind of operation data in the processed internet-of-vehicles data packet and the corresponding acquisition time of the kind of operation data. Specifically, the operating data may be directly stored in the target memory space in a byte storage manner. For the storage of the acquisition time corresponding to each kind of operation data, the acquisition time corresponding to the kind of operation data and the time difference between the acquisition time corresponding to the kind of operation data in the last group of internet-of-vehicles data packets can be stored in the target memory space. For example, when the acquisition time corresponding to the oil consumption data in one group of internet-of-vehicles data packets is stored, the acquisition time corresponding to the oil consumption data in the group of internet-of-vehicles data packets may be differed from the acquisition time corresponding to the oil consumption data in the previous group of internet-of-vehicles data packets to obtain a time difference of the acquisition time, and then the time difference is stored in the target memory space as the acquisition time corresponding to the oil consumption data in the group of internet-of-vehicles data packets. The time difference between the operational data stored in the target memory space and the corresponding acquisition time may then be stored in a designated database, which may be, for example, an HBASE database. Like this, the acquisition time in the car networking data package is saved according to the time difference, can effectively reduce the shared storage space of acquisition time.
FIG. 6 is a flow chart illustrating another method of processing Internet of vehicles data in accordance with an exemplary embodiment. As shown in fig. 6, the transmission time includes an upload time and a receive time, and step 104 may include the steps of:
and 1041, dividing the uploading time corresponding to the first quantity of vehicle networking data packets into a third quantity of uploading time groups according to time intervals.
