Embodiment 1

[0028] figure 1 It is a flow chart of a method for recording unmanned vehicle data provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation of recording the operating data of an unmanned vehicle system. This method can be recorded by an unmanned vehicle data device to execute. The method specifically includes the following steps:

[0029] S110. Obtain the content of the message to be entered through the subscribed channel.

[0030] In the specific embodiment of the present invention, the message refers to the data content transmitted when the functional modules integrated in the unmanned vehicle system (such as sensing, driving, perception and control, etc.) Drive normally. When there is message transmission in the unmanned vehicle system, the message can be used as the content of the message to be entered, so as to be recorded in the file and save the operation data in the unmanned vehicle system.

[0031] In this embodiment, the ...

Embodiment 2

[0051] On the basis of the first embodiment above, this embodiment provides a preferred implementation of the recording method of unmanned vehicle data, which can write the serialized message and its time point and channel information into the file. figure 2 It is a flow chart of a method for recording unmanned vehicle data provided by Embodiment 2 of the present invention, such as figure 2 As shown, the method includes the following specific steps:

[0052] S210. Obtain the content of the message to be recorded through the subscribed channel.

[0053] In the specific embodiment of the present invention, various electronic devices or devices integrated in the unmanned vehicle system, as each functional module in the message transmission topology, have pre-subscribed to the channel corresponding to the message to be received or transmitted, and then run the system The content of the message transmitted by the subscription channel received at the time is the content of the me...

Embodiment 3

[0076] Figure 5 It is a schematic structural diagram of an unmanned vehicle data recording device provided in Embodiment 3 of the present invention. This embodiment is applicable to the situation of recording the operation data of the unmanned vehicle system. The device can realize the data described in any embodiment of the present invention. The recording method of unmanned vehicle data. Specifically, the device includes:

[0077] A message obtaining module 510, configured to obtain the content of the message to be entered through the subscribed channel;

[0078] A block writing module 520, configured to write the message content into the message block to be written if it is detected that there is currently a message block to be written;

[0079] The file writing module 530 is configured to write the message block to be written into the current file to be written if it is detected that the message block to be written meets the cut-off condition.

[0080] Optionally, the ...

Abstract

The embodiment of the invention discloses a method, device, equipment and storage medium for recording unmanned vehicle data. The method includes: obtaining the content of the message to be entered through a subscribed channel; if it is detected that there is currently a message block to be written, writing the message content into the message block to be written; If the message block satisfies the deadline condition, the message block to be written is written into the current file to be written. In the embodiment of the present invention, the message block to be written that is currently writing data is used as the carrier of the message, and when the cut-off condition is satisfied, that is, when the message block to be written is completed, the block to be written is directly written to the current block to be written. Into the file, the effective recording of the operation data of the unmanned vehicle system is realized, and the accuracy and efficiency of data storage are improved, which provides a basis for the traceability of the operation data of the unmanned vehicle system in the later stage.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of unmanned vehicles, and in particular to a method, device, device and storage medium for recording data of unmanned vehicles. Background technique [0002] With the development of science and technology, more and more smart devices are pouring into people's lives to improve people's quality of life and experience, and unmanned vehicles are one of them. [0003] The unmanned vehicle integrates radar, camera, satellite positioning, autonomous navigation and a variety of sensors and other equipment. During the driving process of the unmanned vehicle, the user only needs to input the destination address to the unmanned vehicle system, and the unmanned vehicle can independently locate and determine Navigation routes, automatic identification of traffic signs and road conditions and other information, through a large amount of data information to drive unmanned vehicles to drive safely to t...
