Referring to fig. 1, a method for sharing data of a whole vehicle controller according to a first embodiment of the present invention is shown, where the method for sharing data of a whole vehicle controller according to the present embodiment can encrypt a preset cloud server in real time, so that the problems of data leakage and loss can be effectively avoided, and meanwhile, user experience is improved.
Specifically, the method for sharing data of the whole vehicle controller provided by the embodiment specifically includes the following steps:
step S10, establishing wireless communication connection among all vehicle controllers in real time through a alliance chain to construct a corresponding target block chain network, wherein the target block chain network is a closed network;
step S20, each whole vehicle controller is respectively converted into corresponding block chain nodes based on the target block chain network, and a plurality of vehicle control data sets uploaded by each block chain node in real time are received in real time;

and S40, carrying out real-time encryption processing on the preset cloud server, and generating an encryption key corresponding to the preset cloud server so that a user can acquire data from the preset cloud server through the encryption key.
Specifically, in the present embodiment, it should be first noted that, the method for sharing data of the whole vehicle controller provided in the present embodiment is implemented based on the existing blockchain technology, where the federation chain is a way of constructing a blockchain network, and may be implemented based on the existing technology. Based on this, in order to connect each vehicle controller as a whole, the current vehicle controllers are connected together through wireless communication by the existing alliance chain, further, a required target blockchain network can be constructed, and the target blockchain network is closed, i.e. external personnel cannot enable the target blockchain network. On the basis, in order to facilitate data acquisition, each whole vehicle controller in the current target blockchain network needs to be further converted into corresponding blockchain nodes respectively, so that a vehicle control data set acquired by each blockchain node in real time at present can be received in real time.
Further, after the required vehicle control data sets are acquired, the transmission priority among the current vehicle control data sets, that is, the sequence of uploading the transmission priority to the preset cloud server, is further set. Furthermore, after the storage of the vehicle control data set is completed through the preset cloud server, the current preset cloud server is further subjected to real-time encryption processing, wherein in order to facilitate the subsequent opening, a corresponding encryption key is also generated in real time, so that in the subsequent use process, a user can directly open the preset cloud server through the encryption key, and the required vehicle data is obtained from the preset cloud server.
Second embodiment
Specifically, in this embodiment, it should be noted that, the step of establishing, in real time, wireless communication connection between the respective vehicle controllers through the alliance chain to construct the corresponding target blockchain network includes:
sending a communication connection request to each whole vehicle controller in real time, and receiving the controller model fed back by each whole vehicle controller in real time;
extracting a connection script contained in the alliance chain, and creating a communication link adapted to each whole vehicle controller according to the connection script and the controller model;
and establishing wireless communication connection among the whole vehicle controllers in real time through the communication links.
In particular, in this embodiment, it should be noted that, since each new energy electric vehicle produced is unique, the whole vehicle controller installed in each vehicle is also unique, that is, the model of each whole vehicle controller is different. Based on this, it is necessary to separately establish communication links separately adapted to each of the vehicle controllers. Specifically, a communication connection request is first sent to each current whole vehicle controller in real time, and at the same time, after each whole vehicle controller receives the communication connection request, a required controller model is fed back correspondingly, and specifically, the controller model is composed of a series of codes.
Furthermore, the required connection script is extracted from the preset alliance chain, meanwhile, the communication link adapted to each whole vehicle controller is created by combining the current connection script and the controller model, and based on the communication link, wireless communication connection between the whole vehicle controllers can be established according to the communication links.
Specifically, in this embodiment, it should be further noted that the step of creating the communication link adapted to each vehicle controller according to the connection script and the controller model includes:
extracting a connection code contained in the connection script, and extracting a model code contained in the controller model;
the connection codes and the model codes are subjected to fusion processing to generate corresponding communication codes, and the communication codes are subjected to serialization processing through a DTW algorithm to generate corresponding communication sequences;
and assigning corresponding communication addresses to the communication sequences so as to correspondingly generate the communication links.
Specifically, in this embodiment, it should be further noted that, after the required connection script is obtained through the above steps, in order to facilitate accurate creation of a communication link adapted to each vehicle controller, a connection code included in the current connection script is further extracted, and at the same time, a model code included in the current controller model is synchronously extracted. Based on the above, the current connection code and the model code can be fused, and corresponding communication codes can be generated, and specifically, the current connection code and the model code are composed of a series of letters and numbers and can be identified by a computer. Furthermore, the current communication codes are further processed in a serialization manner through the existing DTW algorithm so as to correspondingly generate communication sequences which can be recognized by the vehicle controllers, and meanwhile, communication addresses which are matched with the preset cloud server are added to the current communication sequences, so that the communication links can be accurately generated.
Third embodiment
In addition, in this embodiment, it should be noted that the step of determining the transmission priorities among the plurality of vehicle control data sets according to the preset rule includes:
detecting a time stamp generated when each block chain node uploads the vehicle control data set in real time, and detecting the data quantity contained in each vehicle control data set one by one;
and generating the transmission priority in real time according to the time stamp and the data quantity, wherein the transmission priority is unique.
In addition, in the present embodiment, it should be noted that, in order to enable the received vehicle control data sets to be simply and quickly sequentially transmitted to the preset cloud server, storage efficiency is improved. Specifically, it is necessary to first detect, in real time, a time stamp generated when each blockchain node uploads a vehicle control data set corresponding to the current blockchain node, where the time stamp specifically includes "time-minutes-seconds", and simultaneously detect the data amount contained in each vehicle control data set.
Furthermore, the required transmission priority can be correspondingly generated in real time only according to the currently acquired time stamp and the data quantity, so that the subsequent processing is facilitated.
In addition, in this embodiment, it should be further noted that the step of generating the transmission priority in real time according to the timestamp and the data amount includes:
sequencing a plurality of vehicle control data sets once according to the sequence generated by the time stamps so as to generate corresponding initial priority;
and detecting the occupied space of the data quantity corresponding to each vehicle control data set one by one, and secondarily sequencing the initial priority according to the sequence from large to small so as to correspondingly generate the transmission priority, wherein the time stamp has uniqueness.
In addition, in this embodiment, it should be further noted that, after the required time stamp and the data amount are obtained through the above steps, the sequence of the time corresponding to each time stamp needs to be compared one by one, and each vehicle control data set is ordered once based on the sequence of each time stamp, where the closer the time stamp is to the 0 point, the higher the ranking corresponding to the time stamp is.
Further, it is also necessary to detect the occupied space required by each data amount one by one, and at the same time, compare one by one, and perform secondary sorting on the plurality of vehicle control data sets in the initial priority according to the order from large to small, where the larger the occupied space is, the more front the rank of the vehicle control data set corresponding to the occupied space is, based on this, the transmission priority can be finally generated, so as to facilitate subsequent processing.
Fourth embodiment
In this embodiment, it should be noted that, the method further includes:
when the encryption key is acquired, the encryption key is issued to the mobile terminal of the user, and the encryption key and the mobile terminal of the user are bound together;
when the user starts the preset cloud server through the encryption key, a verification code is issued to the mobile terminal of the user, so that the user starts the preset cloud server after passing verification of the verification code, and the verification code has uniqueness.
In this embodiment, it should be noted that, in order to facilitate the user to start the preset cloud server, specifically, the generated encryption key is also bound with the mobile terminal of the user in real time, that is, a corresponding relationship between the generated encryption key and the mobile terminal of the user is established.
Furthermore, in the actual use process, when the user starts the preset cloud server through the encryption key, the verification code is issued to the mobile terminal of the current user in real time, and the preset cloud server is started only after the current user passes the verification of the verification code, so that the user can acquire data.
Fifth embodiment
In this embodiment, it should be noted that, the method further includes:
after the user starts the preset cloud server through the encryption key and the verification code, the encryption key is updated in real time to generate a corresponding secondary encryption key, and the secondary encryption key is resent to the mobile terminal of the user.
In this embodiment, it should be noted that, after detecting that the user opens the preset cloud server through the encryption key and the verification code in real time, in order to improve the security performance of the current preset cloud server, the encryption key is further updated in real time to generate a corresponding secondary encryption key.
Further, the current secondary encryption key is also issued to the mobile terminal of the user, so that the user can continuously start the preset cloud server, and meanwhile, the confidentiality of data and the use experience of the user are improved.
