As shown in fig. 1, fig. 1 is a schematic flowchart of a method for transmitting data of an autonomous vehicle according to an embodiment of the present disclosure. The method is applied to a first server, wherein the first server is used for being connected with at least one storage device, the at least one storage device is used for storing vehicle data of an automatic driving vehicle, and the method specifically comprises the following steps:
step S101: determining the priority of the vehicle data according to information sent by a user in a case where the at least one storage device is connected to the first server.
In an embodiment of the application, the first server may be used as a work node (agent) in the automatic driving vehicle control system, at least one interface for connecting the storage device may be arranged in the first server, and after the automatic driving vehicle runs, the at least one storage device of the automatic driving vehicle may be pulled out and connected to the first server. For example, the at least one storage device may be directly inserted into the transmission interface of the first server, or the at least one storage device may be connected to the transmission interface of the first server through a data connection line, which is not specifically limited in this embodiment of the present application.
In this embodiment, after the at least one storage device is connected to the first server, the first server may preview the vehicle data stored in the at least one storage device, and specifically, the first server may read a data identifier of the vehicle data stored in the at least one storage device, and read a storage address of the vehicle data in the at least one storage device, and the like. Further, the first server may determine the priority of the vehicle data according to the information transmitted by the user.
In the embodiment of the application, the first server may receive information input by a user and determine the priority of the vehicle data through the information, for example, the user may input a time period in which the data is expected to be transmitted first, and the first server may set the priority of the data in the time period to be the highest priority; the first server may also receive the priority of the vehicle data determined by the other servers according to the information sent by the user, and the embodiment of the application does not limit the specific manner in which the first server determines the priority of the vehicle data according to the information sent by the user.
As an optional implementation manner of the embodiment of the present application, the determining the priority of the vehicle data according to the information sent by the user includes: uploading a data identifier of the vehicle data to a second server; and receiving the priority determined by the second server for the vehicle data according to the information sent by the user.
In specific application, in a management system of an automatic driving vehicle, a central control node is usually set, the central control node can be used for scheduling each working node, and a second server in the embodiment of the present application can be used as a central control node (master).
In the running process of the automatic driving vehicle, if abnormal running or unexpected other conditions occur, the automatic driving vehicle is usually taken over manually, and the vehicle number of the automatic driving vehicle and the time point of taking over manually are reported to the second server through the network. For example, the time period may be a time within the first 10 minutes to 30 minutes of the manual takeover time point.
After the at least one storage device is connected to the first server, the first server may send the preview condition of the vehicle data stored in the at least one storage device and the vehicle number of the autonomous vehicle to the second server, and the server may set data generated by the autonomous vehicle in the time period as data with the highest priority according to a correspondence between the vehicle number stored before and the time period, and set the priority as the first server, and then the first server receives the priority and further obtains the data according to the priority.
Step S102: the vehicle data is retrieved from the at least one storage device according to the priority.
In this embodiment, the first server may obtain the vehicle data from the at least one storage device according to the order of priority from high to low. Specifically, the first server may copy or cut the vehicle data from the at least one storage device according to an order of priority from high to low, which is not specifically limited in the embodiment of the present application.
In summary, the present application provides a method and an apparatus for transmitting vehicle data automatically, after at least one storage device for storing vehicle data of an automatically driven vehicle is connected to a first server, the first server first determines a priority of the vehicle data according to information sent by a user, and then obtains the vehicle data from the at least one storage device according to the priority. It can be understood that the information sent by the user can indicate information related to data helpful for analysis and research and development of the autonomous vehicle, and when the server acquires the data, the data with high priority can be preferentially acquired, so that the data helpful for analysis and research and development of the autonomous vehicle can be preferentially acquired, the autonomous vehicle can be preferentially analyzed according to the data helpful for analysis and research and development of the autonomous vehicle, and the efficiency of analyzing the data is improved.
Optionally, on the basis of the embodiment corresponding to fig. 1, in the method for automatically transmitting data of a vehicle provided in the embodiment of the present application:
the information comprises time information, and the vehicle data comprises a data generation time identifier; determining the priority of the vehicle data according to information sent by a user, comprising: according to the time information, determining the priority of the vehicle data with the data generation time identification matched with the time information as a first priority; determining the priority of data except the data corresponding to the first priority in the vehicle data as a second priority; wherein the first priority is higher than the second priority. The vehicle data corresponding to the first priority is first priority data, and the vehicle data corresponding to the second priority is second priority data.
As a specific implementation manner of the embodiment of the application, the information sent by the user includes time information, and the vehicle data includes a data generation time identifier, so that the data generation time identifier of the vehicle data may be matched with the event information, if the data generation time identifier is matched with the time information, the vehicle data whose data generation time identifier is matched with the time information may be used as first priority data, data other than the first priority data in the vehicle data is used as second priority data, and the priority of the first priority data is higher than that of the second priority data. Therefore, the first priority data can be acquired by the first server first, and the second server can further finish acquiring the second priority data after finishing acquiring the first priority data.
Optionally, as shown in fig. 2, the step S102 of obtaining the vehicle data from the at least one storage device according to the priority includes:
step S1021: and inserting the address of the first priority data into a first queue.
In the embodiment of the present application, the address of the first priority data may be inserted into the first queue in an adaptive manner according to an actual application scenario. For example, the addresses of the first priority data may be inserted into the first queue in order of the generation time of the first priority data from the morning to the evening. For example, the addresses of the first priority data may be inserted into the first queue in order from the late to the early of the generation time of the first priority data. For example, the address of the first priority data may also be randomly inserted into the first queue, which is not specifically limited in this embodiment of the present application.
Step S1022: and acquiring the first priority data from the first queue according to the address of the first priority data.
In this embodiment, the first queue may include a first step pointer, and the vehicle data may be acquired from an address corresponding to the head position of the first queue by specification of the first step pointer.
Optionally, when the number of the storage devices is multiple, each storage device corresponds to one slot in the first queue, and the slots corresponding to the addresses of the adjacent first priority data in the first queue are different; the acquiring the first priority data from the first queue according to the address of the first priority data in step S1022 includes: determining current first head of queue data of the first queue through a first stepping pointer; and when the first queue head data is acquired, determining second queue head data in the first queue through the first further pointer.
In the embodiment of the application, a concept of slot (slot) is introduced into the first queue, and each storage device corresponds to one slot in the first queue, so that when the number of the storage devices is multiple, multiple slots exist in the first queue in parallel, and when the first priority data is inserted into the first queue, the slots corresponding to the addresses of the adjacent first priority data in the first queue may be different according to a certain rule.
For example, as shown in fig. 3, taking the case that there are two storage devices, namely a first storage device and a second storage device, the slots of the first storage device and the second storage device corresponding to the first queue in turn are: slot 1 and slot 2, which can be sequentially corresponding to each position in the first queue in a loop manner, when the address of the first priority data is inserted into the first queue, the first priority data stored in the first storage device is inserted into the first slot, and the first priority data stored in the second storage device is inserted into the second slot. Adaptively, when the first server acquires data through a plurality of processes, the first server may first point to the head of line task 1 of the slot position 1 through the first stepping pointer, when the first process acquires data according to the address corresponding to the task 1, the first stepping pointer may point to the head of line task 3 of the slot position 2, the second process may acquire data according to the address corresponding to the task 3, when the second process acquires data according to the address corresponding to the task 3, the first stepping pointer may point to the next head of line task 2 of the slot position 1, the third process may acquire data according to the address corresponding to the task 2, and so on. In this embodiment of the present application, the first priority data acquired by two adjacent processes correspond to different storage devices, which is equivalent to sequentially consuming data on different storage devices, so that a waiting process when different processes acquire data of the same storage device can be avoided, thereby maximizing overall data throughput in data transmission and improving data transmission efficiency.
For example, if multiple processes consume (i.e., acquire) data of one storage device at the same time, the maximum throughput is an input/output (I/O) bandwidth of the storage device, and if multiple processes respectively consume data of multiple storage devices, the maximum throughput is a sum of I/O of all storage devices in the queue at this time.
Step S1023: and acquiring the second priority data after the acquisition of the first priority data is finished.
In the embodiment of the application, after the acquisition of the first priority data is completed, the analysis and the research and the development can be carried out according to the first priority data, and the efficiency of analyzing and researching and developing the automatic driving vehicle is improved.
After the acquisition of the first priority data is completed, the acquisition of the second priority data may be further completed.
It can be understood that, in an actual application scenario, data transmission is usually dynamic, for example, after transmission of first priority data corresponding to an address in a first queue is completed, second priority data is transmitted through an address in a second queue, however, if an address corresponding to the first priority data is inserted into the first queue while the second priority data is transmitted according to the second queue, a transmission process of the second queue may be terminated, and after first priority data of data in the first queue is processed preferentially, a corresponding process of the second queue is performed.
In specific application, the second priority data can be acquired in an adaptive manner according to an actual application scene. For example, the second priority data may be acquired according to a time sequence of generation of the second priority data, or the second priority data may be acquired from each storage device in sequence according to a storage device in which the second priority data is stored, or the second priority data may be acquired randomly, which is not specifically limited in this embodiment of the application.
Optionally, the acquiring the second priority data includes: inserting an address of first data in the second priority data into a second queue; the first data is: among the second priority data, data stored in a storage device having a high reading speed among the plurality of storage devices; acquiring the first data from the second queue according to the address of the first data; inserting an address of second data in the second priority data into a third queue; the second data is: among the second priority data, data stored in a storage device having a low reading speed among the plurality of storage devices; and acquiring the second data from the third queue according to the address of the second data.
In the embodiment of the application, it is considered that the reading speeds corresponding to different storage devices may be different, for example, the reading speed of the NVMe disk is much faster than that of the USB slot disk, and if the disk data with different reading speeds are set in one queue, a phenomenon may occur in which a process corresponding to a storage device with a fast reading speed waits for a storage device with a slow reading speed after the reading is completed, so that the transmission rate is affected. Therefore, in this embodiment of the present application, the second priority data may be further divided according to the reading speed of the storage device, and specifically, the second priority data is further divided according to the reading speed of the storage device: first data in a storage device with a high reading speed, and second data in a storage device with a low reading speed. And further inserting the address of the first data into the second queue, acquiring the first data from the second queue, inserting the address of the second data into the third queue, and acquiring the second data from the third queue.
In the embodiment of the application, the address of the first data can be inserted into the second queue in an adaptive manner according to the actual application scenario.
