Fig. 4 is a flowchart of a method for implementing data upload by each device in the data upload system provided in the embodiment of the present application, and referring to fig. 4, the method includes:
401. when the vehicle-mounted terminal detects a data transmission request sent by any sensor deployed on the vehicle in the driving process of the vehicle, the driving information carried in the data transmission request is stored in a first local storage medium of the vehicle-mounted terminal.
In the embodiment of the present application, the vehicle may be a vehicle supporting automatic driving, and various sensors may be deployed on the automatic driving vehicle, such as a camera, a millimeter wave radar, a laser radar, a speed sensor, an acceleration sensor, a temperature sensor, a humidity sensor, and the like. The state information of the surrounding environment and the state information of the vehicle itself, such as temperature, wind speed, vehicle speed, the number of surrounding vehicles, the number of kilometers traveled, the number of remaining fuel, etc., may be collected in real time by the various sensors during the travel of the vehicle. In the embodiment of the present application, the above-mentioned state information is collectively referred to as driving information collected by a sensor.
In one possible implementation, the in-vehicle terminal may store the travel information according to a time stamp of the travel information. Correspondingly, the steps can be as follows: for any sensor deployed on the vehicle, when detecting a data transmission request sent by the sensor, the vehicle-mounted terminal may analyze the data transmission request and obtain the driving information carried in the data transmission request. The in-vehicle terminal may store the travel information to the first local storage medium according to the time stamp of the travel information.
The vehicle-mounted terminal can start a plurality of analysis servers through a plurality of threads, each analysis server analyzes one data transmission request to obtain the running information carried in each data transmission request, and the vehicle-mounted terminal can respectively store the running information obtained in a period of time into a first local storage medium of the vehicle-mounted terminal according to the sequence of the timestamps.
For example, when the temperature sensor acquires the current ambient temperature a, the ambient temperature a and the acquisition time a thereof are sent to the in-vehicle terminal through a data transmission request, and when the speed sensor acquires the current running speed B, the running speed B and the acquisition time B thereof are sent to the in-vehicle terminal through a data transmission request. The vehicle-mounted terminal obtains the ambient temperature A, the acquisition time a, the running speed B and the acquisition time B after analysis, and the vehicle-mounted terminal stores the ambient temperature A and the acquisition time a in a hard disk of the vehicle-mounted terminal and stores the running speed B and the acquisition time B in the hard disk of the vehicle-mounted terminal because the acquisition time B is later than the acquisition time a.
402. When detecting that the running information stored in the first local storage medium is not less than the first target data volume, the vehicle-mounted terminal packages the stored running information into a plurality of data packets, and stores the plurality of data packets in the first local storage medium.
In the embodiment of the application, the vehicle-mounted terminal can detect the data volume of the stored driving information in the first local storage medium in real time, and when the stored driving information is detected to be not less than the first target data volume, the vehicle-mounted terminal can start the corresponding packaging service. The packaging service can be a service provided in the vehicle-mounted terminal system and can also be a service provided by an application program installed in the vehicle-mounted terminal. Wherein the first target data amount is the lowest data amount that triggers the packaging service.
In one possible implementation manner, the vehicle-mounted terminal may perform real-time detection and data packaging on the data amount of the driving information stored in the first local storage medium by the application program. That is, the vehicle-mounted terminal may have an application program for data packaging installed therein, and the application program may detect the data amount of the stored travel information in real time, and package the stored travel information when a packaging condition is satisfied, that is, the stored travel information is not less than the first target data amount.
In a possible implementation manner, the vehicle-mounted terminal may package the stored driving information into data packets with the same size, and accordingly, this step may be: the in-vehicle terminal detects the data amount of the travel information stored in the first local storage medium. The vehicle-mounted terminal acquires a second target data volume when the data volume of the stored running information is not less than the first target data volume. And the vehicle-mounted terminal divides the stored running information according to a second target data volume to obtain a plurality of data fragments. And the vehicle-mounted terminal packs each data fragment to obtain a plurality of data packets.
It should be noted that the travel information and the plurality of packets obtained by packaging may be stored in different locations in the first local storage medium. To facilitate lookup and unloading.
The in-vehicle terminal may delete the stored travel information after obtaining the plurality of packets. Thus, the storage space of the vehicle-mounted terminal can be saved.
403. And when the number of the plurality of data packets is not less than the first target number, the vehicle-mounted terminal copies the plurality of data packets from the first local storage medium to an external storage medium of the vehicle-mounted terminal.
In the embodiment of the application, the vehicle-mounted terminal may be connected to an external storage medium, where the external storage medium may be a mobile hard disk, a mobile magnetic disk, or another removable storage medium. The external storage medium can be removed from the vehicle-mounted terminal at any time, and data stored in the first local storage medium is not affected. The external storage medium can be connected with the vehicle-mounted terminal through a data transmission cable or an equipment interface configured on the vehicle-mounted terminal.
The vehicle-mounted terminal can detect the number of the data packets stored in the first local storage medium, and when the number of the stored data packets reaches a first target number, the vehicle-mounted terminal can start the copy service and copy all the stored data packets to the external storage medium. The replication server is similar to the packaging service, and may be provided by the vehicle-mounted terminal, or by an application installed on the vehicle-mounted terminal, which is not described herein again. When the number of the stored data packets reaches the first target number, the vehicle-mounted terminal can change the packet to copy when the copying speed is higher than the data packet generating speed, and multiple waiting caused by insufficient number of the data packets which are not copied of the vehicle-mounted terminal is avoided.
In a possible implementation manner, the vehicle-mounted terminal may further mark any data packet after copying the data packet to the external storage medium, so as to avoid repeated copying of the data packet. Correspondingly, the vehicle-mounted terminal can copy the data packet after obtaining any data, namely, the vehicle-mounted terminal does not wait for the number of the data packets to reach the first target number. After any data is obtained, the data packet is copied, so that when the generation speed of the data packet is higher than the copying speed, the vehicle-mounted terminal can be prevented from accumulating excessive uncopied data packets.
It should be noted that the external storage medium may be removed from the in-vehicle terminal by a worker or a transfer device, and then the external device is connected to the electronic device. Wherein, the transfer device can be arranged at the same place with the electronic device, and the electronic device controls the transfer device.
For example, when the vehicle finishes the driving task and returns to the garage, the transfer device may remove the mobile hard disk installed on the vehicle, then transfer the mobile hard disk to the location where the electronic device is located, and access the mobile hard disk to the electronic device, such as a hard disk interface of a plug-in server. Or the above operation is performed by a worker instead of the transferring apparatus.
404. When the electronic equipment detects the access operation of any external storage medium, the electronic equipment determines the copying sequence of the external storage medium.
In this embodiment, the electronic device may be a terminal or a server, and the electronic device may access a plurality of external storage media simultaneously. The server can detect whether the external storage media are accessed in real time, for example, the detection is performed by a device access service, and when an access operation of any external storage media is detected, the electronic device can determine a copying sequence of the external storage media.
In one possible implementation, the electronic device may determine the order of copying based on the vehicle identification. Correspondingly, the steps are as follows: the electronic device may obtain a vehicle identifier of a vehicle corresponding to the external storage medium. The electronic device may determine a replication sequence of the external storage medium based on the vehicle identification.
For example, the electronic device is configured to receive a data packet corresponding to travel information of 10 vehicles, and since the 10 vehicles need to travel in a certain order during the travel process, data collected by each vehicle has a correlation, so as to store the correlated data in a relatively close position. The electronic device can determine the vehicle identifier 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 corresponding to the external storage medium when the external storage medium corresponding to each vehicle accesses. And copying the data in the external storage medium according to the sequence of the vehicle identifications.
In a possible implementation manner, the electronic device may further obtain, in sequence, the at least one data packet included in each external storage medium according to an access sequence of the external storage medium. That is, the vehicle identifier of the vehicle corresponding to the external storage medium is not considered, but is accessed and copied firstly. Therefore, the transmission of the data packet corresponding to the running information of other vehicles is prevented from being influenced when one vehicle fails or returns on time.
In one possible implementation, the electronic device may initiate at least one data replication service based on multi-threading, each data replication service for handling one accessed external storage medium. Due to the adoption of the multithreading technology, the electronic equipment can simultaneously process a plurality of accessed external storage media, so that the time for copying data is saved.
It should be noted that the electronic device may be located in a highly automated garage that is used to manage vehicles within a range of areas. The electronic device can directly send the acquired multiple data packets to a remote data center server. Alternatively, the electronic device may be disposed in a regional data center, the regional data center is connected to a plurality of garages, and the electronic device may monitor the external storage media accessed in each garage, and then execute step 405 and step 406.
405. And the electronic equipment stores the plurality of data packets stored in the external storage medium into a local storage medium of the electronic equipment according to the copying sequence.
In this embodiment of the application, after determining the copy sequence, the electronic device may sequentially copy and store the data packets stored in the accessed external storage medium to a second local storage medium of the electronic device according to the copy sequence.
It should be noted that the electronic device may further process and analyze the plurality of data packets in the second local storage medium. Correspondingly, the steps can be as follows: the electronic equipment unpacks the plurality of data packets to obtain the driving information of at least one vehicle. The electronic device can perform data cleaning or data screening on the driving information. And the electronic equipment analyzes the residual running information after screening.
406. And when the number of the stored data packets in the second local storage medium of the electronic equipment is not less than the second target number, the electronic equipment uploads the stored data packets to the data center server.
In the embodiment of the application, the electronic device may determine the uploading opportunity based on the number of stored data packets. Correspondingly, the steps can be as follows: the electronic equipment acquires uploading sequence information corresponding to each data packet in the stored data packets, wherein the uploading sequence information comprises at least one of vehicle identification, storage time and acquisition time period. The electronic device can sequentially send the stored data packets to the data center server according to the uploading sequence information.
For example, when the upload sequence information is the vehicle identifier, the electronic device may upload a plurality of data packets corresponding to one vehicle and then upload a data packet corresponding to another vehicle according to the sequence of the vehicle identifier. When the uploading sequence information is the storage time, the electronic device may upload the data packets in sequence according to the storage time of the data packets and according to the time sequence. When the uploading sequence is the collection time period, the electronic device may determine the uploading sequence of the corresponding data packets according to the collection time period of the driving information. Of course, the electronic device may also determine the uploading order of each data packet according to a plurality of information.
In one possible implementation manner, the electronic device may send the plurality of data packets stored in the second local storage medium to the data center server every fixed time period. The fixed time period may be daily or weekly, and the embodiment of the present application is not limited.
In one possible implementation, the electronic device may also determine the timing for sending the plurality of data packets according to a network condition. For example, the electronic device may determine a current network transmission speed, and when the network transmission speed is not less than the target transmission speed, the electronic device may send the plurality of data packets stored in the second local storage medium to the data center server; when the network transmission speed is less than the target transmission speed, the electronic device may suspend transmission of the data packet.
In one possible implementation, the electronic device may also determine whether to send the data packet to the data center server according to the number of unsent data packets.
