Figure 1

[0067] Specifically, the present embodiment provides:

[0068] A vehicle machine log acquisition method, specifically comprising the following steps:

[0069] Step S10, when a log acquisition instruction issued by a user is received in real time, a target distance between the user is calculated in real time according to the log acquisition instruction, and it is determined in real time whether the target distance is greater than a preset distance threshold;

[0070] ​Step S20, if the target distance is greater than the preset distance threshold, a first communication chain is sent to the user terminal of the user, and a closed local area network is constructed between the user and the first communication chain.

[0071] Step S30, the log acquisition instruction is analyzed in real time to extract the log acquisition template in the log acquisition instruction, and the corresponding target log is extracted in the vehicle log database through the log acquisition template.

[0072] Specifically, in this embodiment, first of all, in order to meet the needs of different users, that is, to enable users to export vehicle logs in both long range and short range, after receiving the log acquisition instruction sent by the user through the user terminal in real time, the vehicle controller arranged in the vehicle calculates the distance between the current user and the vehicle in real time according to the current log acquisition instruction. Specifically, the distance between the vehicle and the user can be calculated by the existing communication signal propagation speed and the detected propagation time. Based on this, it is judged in real time whether the current target distance is greater than the preset distance threshold, that is, it is judged in real time whether the current user is exporting logs in long range or short range. Preferably, it is judged in real time whether the above-mentioned target distance is greater than 1km. Specifically, if so, it means that the current user is exporting logs in long range, and the vehicle controller needs to send a corresponding first communication chain to the user terminal of the current user. At the same time, a closed local area network between the current vehicle controller and the current user is constructed in real time through the first communication chain.

[0073] Further, in order to enable the current user to quickly extract the target log needed, the current log acquisition instruction needs to be further extracted and analyzed to correspondingly extract the log acquisition template contained in the current log acquisition instruction, and finally the target log needed is extracted in the vehicle log data road in the vehicle through the log acquisition template. The log acquisition template includes the type of log to be acquired and the size of the data amount of the log to be acquired. In this way, the user can quickly complete the remote acquisition of vehicle logs, and the user experience is improved.

[0074] Second embodiment

[0078] sending the first communication chain to the user terminal in real time, and constructing the closed local area network according to the first communication chain and the user terminal, wherein the closed local area network is unique.

[0079] Specifically, in the embodiment, it should be noted that in order to quickly and effectively generate the required closed local area network, the data transmission rate is correspondingly improved, and the data transmission time is correspondingly saved. Specifically, since the log acquisition instruction issued by each user terminal is unique, that is, each user terminal is unique, based on this, the above-mentioned vehicle controller only needs to detect the log acquisition instruction received in real time, and can correspondingly detect the device serial number carried by the current log acquisition instruction, and each device serial number is unique.

[0080] Further, the device identification corresponding to the above-mentioned user terminal is further extracted from the current device serial number, and the user terminal of the current user is further matched according to the device identification, so that the above-mentioned vehicle controller can issue the corresponding first communication chain and construct the above-mentioned closed local area network, so as to facilitate subsequent processing.

[0081] Further, the step of constructing the closed local area network according to the first communication chain and the user terminal comprises:

[0083] a plurality of target communication nodes contained in the first communication chain are detected in real time, and the closed local area network is constructed according to a plurality of original communication nodes and a plurality of target communication nodes, and each original communication node and each target communication node is unique.

[0084] Specifically, in the embodiment, it also needs to be explained that after the vehicle controller sends the first communication chain to the user terminal through the above steps, since each user terminal completes data transmission through the communication module arranged inside, based on this, the communication module contained in the user terminal currently used by the user can be detected, and at the same time, a plurality of original communication nodes contained in the current communication module are extracted synchronously, and further, a plurality of target communication nodes contained in the current first communication chain are detected, wherein the node properties of the current original communication node and the current target communication node are the same, so that the required closed local area network can be further constructed for subsequent processing.

[0085] Third embodiment

[0086] Further, the step of constructing the closed local area network according to the plurality of original communication nodes and the plurality of target communication nodes comprises:

[0087] adding a corresponding first identifier to each of the original communication nodes, and adding a corresponding second identifier to each of the target communication nodes;

[0088] constructing a corresponding mapping relationship according to the first identifier and the second identifier, and replacing each of the original communication nodes with each of the target communication nodes based on the mapping relationship to construct a corresponding target communication network in the communication module;

[0089] constructing the closed local area network according to the target communication network, and the target communication network has uniqueness.

[0090] In addition, in the embodiment, it needs to be explained that after the plurality of original communication nodes and the plurality of target communication nodes are detected respectively through the above steps, in order to quickly complete the replacement of subsequent nodes, a first identifier can be added to each of the original communication nodes, and a second identifier can be added to each of the target communication nodes, and the current first identifier and the second identifier can be numbers or letters.

[0091] Further, according to the corresponding relationship between each first identifier and each second identifier, a mapping relationship therebetween is constructed, and each original communication node in the above communication module can be replaced with a corresponding each target communication node directly according to the current mapping relationship, and a corresponding target communication network is generated in the current communication module, based on which, the required closed local area network is further constructed, wherein the above target communication network has uniqueness for subsequent processing.

[0092] Further, the step of constructing the closed local area network according to the target communication network comprises:

[0093] When the target communication network is generated in real time, a communication completion instruction is received in real time feedback of the target communication network, and a corresponding blockchain network is generated according to the communication completion instruction;

[0094] The target communication network is correspondingly mapped into the blockchain network to correspondingly generate the closed local area network, and the blockchain network is a network with a closed structure.

[0095] In addition, in the embodiment, it also needs to be explained that after the target communication network required is constructed in real time through the above steps, the target communication network automatically feeds back the corresponding communication completion instruction to the above vehicle controller, and at the same time, the current vehicle controller calls the blockchain network set in the background server according to the communication completion instruction, and further, only needs to correspondingly map the target communication network into the current blockchain network to automatically generate the closed local area network, wherein, since the structure of the blockchain network is closed, the structure of the generated closed local area network is also closed, so as to facilitate subsequent processing.

[0098] If it is judged in real time that the target distance is less than the preset distance threshold, a second communication chain is sent to the user terminal of the user, and a corresponding log is directly sent to the user through the second communication chain, and the second communication chain has uniqueness.

[0099] In the embodiment, it needs to be pointed out that, correspondingly, if it is judged in real time through the above steps that the target distance between the vehicle and the user is less than the preset distance threshold, it is correspondingly indicated that the current user is in the log of the vehicle in the short range, so that the above closed local area network does not need to be constructed, and a second communication chain is correspondingly sent to the user terminal of the user, and at the same time, the vehicle controller directly sends the log required by the user in real time through the second communication chain, which correspondingly improves the user experience.
