when the number of the files contained in the first safety information list is consistent with that of the files contained in the second safety information list, matching the names, paths, modification dates and hash values of the files contained in the first safety information list and the second safety information list one by one;
and when one or more attribute values of the name, the path, the modification date and the hash value of any file contained in the first safety information list and the second safety information list are inconsistent, outputting unavailable safety prompt information of the charging pile.
In the above method for detecting charging safety of an electric vehicle, the charging pile establishes a communication connection with the cloud server through a wired communication module or a wireless communication module, and the method further includes:
after charging is finished, the charging pile acquires the payment state of the charging transaction from the cloud server;
when the payment state of the charging transaction is successful, the charging pile detects the connection state of a charging cable between the electric automobile and the charging pile in real time;
when the charging pile detects that the charging cable is disconnected with the charging pile, a charging pile resetting program is executed;
the charging pile downloads a reset data packet from the cloud server;
and the charging pile resets the files in the nonvolatile storage space of the charging pile by using the reset data packet.
Because charging data and transaction data all can upload and store on the cloud ware, need not to remain any data record on filling electric pile for a long time, consequently charge at every turn and reset filling electric pile and can not influence the normal use that fills electric pile. By adopting the technical scheme of the embodiment, after the charging pile executes resetting every time, the files in the nonvolatile storage space of the charging pile are restored to the initial state before use, and the security information data of the files in the initial state are stored in the cloud server. After each reset is executed and before the electric automobile is connected with the charging pile for charging next time, if files on the charging pile comprise executable program files, dynamic link library files, static link library files or data files and the like which are maliciously distorted, for example, an attacker replaces the charging program files on the charging pile with cracked or modified files, or places a trojan program and the like on the charging pile, the second safety information list obtained by the charging pile through executing safety scanning by using the safety information scanning script is inconsistent with the first safety information list provided by the cloud server, so that the safety problem can be timely found, and the electric automobile is prevented from being attacked during charging.
In the above method for detecting charging safety of an electric vehicle, after the step of matching the first safety information list with the second safety information list by the electric vehicle, the method further includes:
and when the information in the first safety information list is inconsistent with the information in the second safety information list, the electric automobile sends matching failure information to the charging pile.

and the charging pile resets the files in the nonvolatile storage space of the charging pile by using the reset data packet.
By adopting the technical scheme of the embodiment, when the information in the first safety information list is inconsistent with the information in the second safety information list, the electric automobile sends matching failure information to the charging pile. In this case, after the charging post is reset last time, there is a possibility of being attacked and falsified before the security information scanning is performed this time, and the charging operation may be performed after the charging post is reset again.
In some embodiments of the present invention, after the step of starting the charging control program by the charging pile, the method further includes:
the charging pile detects the file operation executed by the charging control program on the nonvolatile storage space of the machine in real time;
and when the operation type of the file operation is a new file or read-write, write-only or additional operation on an existing file in a nonvolatile storage space of the local computer, recording a corresponding file name, path and operation type to generate a file operation list.
In other embodiments of the present invention, after the step of starting the charging control program by the charging pile, the method further includes:
the charging pile detects file operation executed by any program on a nonvolatile storage space of the charging pile in real time;
and when the operation type of the file operation is a new file or read-write, write-only or additional operation on an existing file in a nonvolatile storage space of the local computer, recording a corresponding file name, path and operation type to generate a file operation list.
In the technical scheme of the above embodiment, only the writing operation of the application program or the service program to the file in the nonvolatile storage space of the charging pile, i.e. the new file, the writing only, the reading and writing or the adding operation, is recorded in the file operation list, and the read-only operation of the application program or the service program to the file in the nonvolatile storage space of the charging pile is not required to be recorded.
In some embodiments of the invention, the programs on the charging post other than the charging control program and the transaction service program are configured to have read-only rights to files in the non-volatile storage space of the charging post.
In the above method for detecting safety of electric vehicle charging, before the step of downloading a reset data packet from the cloud server by the charging pile, the method further includes:
generating a modified file list in units of files based on the file operation list, the modified file list including files already existing in a local nonvolatile storage space and recorded in the file operation list before the charging control program is started;
and the charging pile sends the modified file list to the cloud server so that the cloud server generates the reset data packet according to the modified file list.
Specifically, the file operation list is recorded in units of operation events such as file read operations, file write operations, and the like, and each time an operation record is generated by detecting an operation event, the same file may be operated by one or more programs for multiple times, so as to generate multiple operation records in the file operation list. The modified file list is generated by taking files as a unit, namely each file corresponds to one record in the modified file list.
In the above method for detecting charging safety of an electric vehicle, the step of generating the reset data packet by the cloud server according to the modified file list specifically includes:
reading first basic data corresponding to the files in the modified file list from a database;
acquiring current system time as a random seed to generate a random number;
writing the random number to a dynamic flag bit in the first base data to generate second base data;
generating a target file based on the second basic data;
acquiring the name, the path, the modification date and the hash value of the target file and writing the name, the path, the modification date and the hash value into a database;
and packaging the target file into the reset data packet to be sent to the charging pile.
Specifically, the first basic data is source code data corresponding to a file in a nonvolatile storage space of the charging pile or metadata stored in a database. The dynamic flag bit is a specific position in the first basic data that is configured in advance, for example, when a file in the modified file list is an executable program file, the corresponding first basic data is source code data of the executable program file, the dynamic flag bit is a certain line in the source code data, after the cloud server generates a random number, the random number is inserted into the position of the corresponding line of the source code data in an annotation manner, and then the source code data is compiled to obtain an object file of the executable program file. After the cloud server generates the target file, the name, the path, the modification date and the hash value of the target file are read and written into a database, and when the electric automobile is connected with the cloud server, the data are read from the database to generate a first safety information list.
In the above method for detecting charging safety of an electric vehicle, the step of resetting the file in the nonvolatile storage space of the electric vehicle by using the reset data packet by the charging pile specifically includes:
scanning files in the file operation list;
acquiring process information associated with the files in the file operation list to generate an associated process list;
and when any process in the association process list is a system process, the charging pile executes system resetting, otherwise, the charging pile executes the system resetting.
Specifically, the process information associated with the file refers to information such as a name and a program path of a process that has performed a write operation on the file in the nonvolatile storage space of the charging pile and is in a running state, and when the file itself on which the write operation is performed is an executable program file, the process information associated with the file refers to information such as a name and a program path of a process generated by executing the executable program file. The system process refers to a process providing basic functions of the system, such as a memory management process, an input/output management process, and a load balancing process kernel process, and the system process cannot be closed or the closing of the system process causes system crash, or cannot run normally, or cannot be used.
In the above method for detecting charging safety of an electric vehicle, the step of resetting the charging pile execution system specifically includes:
the charging pile enters a minimum operation state, and the charging pile stops operating other processes except necessary processes required by the maintenance of the downloading service in the minimum operation state;
the charging pile and the cloud server download a system recovery mirror image;
after the system recovery mirror image is downloaded, restarting the charging pile to enter a system resetting state;
and the charging pile resets the files in the nonvolatile storage space of the charging pile by using the system mirror image.
Specifically, when a file to be reset is locked by a system process, directly closing the system process may cause system crash, abnormal operation or non-use, and in a severe case, the system file may be damaged, or even a hardware facility may be damaged. By adopting the technical scheme of the implementation mode, when the association process list contains the system process, the charging pile system is possibly invaded and distorted greatly, the complete system recovery mirror image of the charging pile system is downloaded from the cloud server to reset the charging pile comprehensively, the influence caused by the distortion of the system process can be eliminated completely, and the safety of the charging pile is improved.
In the above method for detecting charging safety of an electric vehicle, the step of executing the warm reset by the charging pile specifically includes:
stopping running the process in the associated process list;
deleting the file with the operation type of the new file in the file operation list;
decompressing the reset packet to write the target file in the reset packet to a temporary directory;
acquiring a target path of each target file;
and moving the target file to a corresponding target path to cover the original target file.
Specifically, the hot reset is that the covered reset operation is directly executed on the file to be reset under the condition that the system is not restarted, and when the file to be reset does not relate to the system process, a hot reset scheme can be adopted to improve the reset efficiency.
In the above method for detecting charging safety of an electric vehicle, after the step of moving the target file to the corresponding target path to cover the original target file, the method further includes:
determining necessary processes for realizing the basic functions of the charging pile in a standby state from the associated process list;
the necessary processes are restarted.
The basic functions of the charging pile comprise a user interaction function, a communication function, a time synchronization function, a payment function and the like, and the necessary processes for realizing the basic functions of the charging pile comprise a user interaction application process for providing a user interaction interface, a time synchronization process for providing a time synchronization service, a communication management process for providing a communication service, a payment application process for providing a payment service and the like. Since not all processes in the associated process list are essential processes, even some processes may be Trojan horse processes, only the essential processes that are shut down are restarted after the warm reset is performed, not all processes in the associated process list.
The invention provides a charging safety detection method of an electric automobile, wherein the electric automobile is in communication connection with a charging pile through a charging cable to obtain identity identification information of the charging pile, is in communication connection with a cloud server through a wireless communication module, downloads a safety information scanning script and a first safety information list of the charging pile from the cloud server, transmits the safety information scanning script to the charging pile through the charging cable so that the charging pile executes safety scanning by using the safety information scanning script to obtain a second safety information list, matches the first safety information list with the second safety information list, and sends matching success information to the charging pile to enable the charging pile to start a charging intrusion control program when information in the first safety information list is consistent with information in the second safety information list in a one-to-one correspondence mode, so that risk investigation can be performed on the charging pile, and the charging safety of the electric automobile is improved.
