s10: program source codes in the computer and executable codes compiled according to the program source codes are stored in the target direct current control protection equipment in advance.
First, a program source code is written in a computer, an executable code is compiled from the program source code, and then the program source code and the executable code in the computer are stored in a target direct current control protection device.
Note that, the manner of storing the program source code and the executable code in the target dc control protection device may be to store the program source code and the executable code in a memory of the target dc control protection device itself, or may be to store a new memory in the target dc control protection device, which is not limited in this embodiment. It can be understood that by means of storing the new memory in the target dc control protection device, when the target dc control protection device needs to be replaced, the new memory can be directly set on the replaced target dc control protection device, so that the need of executing the storing operation again is avoided, and the content of the program source code and the executable code stored in the replaced target dc control protection device can be ensured to be consistent with the content stored before the replacement.
S20: and after receiving an updating instruction for updating the target executable code, acquiring the target program source code corresponding to the target executable code from the target direct current control protection equipment.
After receiving an update instruction for updating the target executable code, determining the target executable code from executable codes stored in the target direct current control protection equipment according to the update instruction, and determining a corresponding target program source code according to the corresponding relation between the executable code and the program source code so as to acquire the target program source code from the target direct current control protection equipment.
S30: and modifying the source code of the target program, compiling, and burning the compiled executable code to the target direct current control protection equipment.
Specifically, after the target program source code corresponding to the target executable code is obtained, the target program source code may be modified, then the modified target program source code is compiled to obtain a corresponding executable code, that is, an updated executable code, and then the updated executable code is burned into the target direct current control protection device, so as to complete updating of the target executable code in the target direct current control protection device.
According to the executable code updating method in the direct current control protection equipment, the executable code and the corresponding program source code are stored in the target direct current control protection equipment in advance, so that after an updating instruction for updating the target executable code is received, the target program source code corresponding to the target executable code can be acquired from the target direct current control protection equipment; therefore, the source code of the target program can be modified and compiled, and then the compiled executable code is burnt into the target direct current control protection equipment, so that the update of the target executable code in the target direct current control protection equipment is realized; in addition, the method acquires the target program source code corresponding to the target executable code from the target direct current control protection equipment, so that the target program source code and the target executable code can be ensured to be corresponding, the accuracy and the effectiveness of the modified target executable code can be relatively ensured, and the safety and the stability of the direct current control protection system are further ensured.
On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, this embodiment further includes:
program check codes calculated according to the program source codes, the program source codes and executable codes corresponding to the program source codes are stored in the target direct current control protection device in advance.
Correspondingly, after receiving an update instruction for updating the target executable code, the method further comprises:
calculating a corresponding first check code according to a program source code stored in a computer;
judging whether the program check code is the same as the first check code;
if yes, setting a program source code in the computer as a target program source code, and entering a step of modifying the target program source code and compiling, and burning the compiled executable code to target direct current control protection equipment;
if not, the method enters a step of acquiring target program source codes corresponding to the target executable codes from the target direct current control protection equipment.
Specifically, compared with the previous embodiment, the present embodiment further calculates a corresponding program check code according to the program source code, and then stores the program source code, the executable code corresponding to the program source code, and the program check code to the target dc control protection device. It will be appreciated that, during the daily operation, the program source code in the computer may be modified or deleted due to poor management, malicious damage, etc., so that after receiving an update instruction for updating the target executable code, it is determined whether the program source code stored in the computer and the program source code stored in the target dc control protection device are identical by comparing whether the first check code calculated from the program source code stored in the computer and the program check code stored in the target dc control protection device are identical.
If the executable code is the same, the program source code stored in the computer can be directly used as the target program source code, the target program source code is modified and compiled, and the updated executable code is obtained and burnt to the target direct current control protection equipment;
if not, it means that the program source code stored in the computer is modified, and therefore the program source code is different from the program source code in the target dc control protection apparatus, and therefore it is necessary to obtain the target program source code corresponding to the target executable code from the target dc control protection apparatus.
It can be seen that, in this embodiment, by storing the program check code calculated according to the program source code, and the executable code corresponding to the program source code in advance in the target dc control protection device, and then after receiving the update instruction for updating the target executable code, determining whether the program check code is the same as the first check code calculated according to the program source code stored in the computer, under the same condition, the program source code stored in the computer can be directly used for modifying, thereby avoiding the process of transmitting the target program source code from the target dc control protection device, and relatively improving the convenience of operation.
On the basis of the above embodiment, the present embodiment further describes and optimizes the technical solution, specifically, stores, in advance, a program check code calculated according to a program source code, the program source code, and an executable code corresponding to the program source code, in correspondence to a target dc control protection device, specifically:
a storage table is set in target direct current control protection equipment in advance;
and storing the program check code calculated according to the program source code, the executable code corresponding to the program source code and the corresponding burning time according to the format of a storage table.
Specifically, in this embodiment, a storage table is set in the target dc control protection device in advance, where the storage table is correspondingly set with a storage format, for example, a program check code, a program source code, an executable code corresponding to the program source code, and a corresponding burning time are respectively set in the table header of each row or each column of the storage table, and each time a new set of data needs to be stored, the corresponding program check code, the program source code, the executable code, and the burning time are stored in a manner of adding one row or one column. Therefore, in the subsequent operation process, all the contents stored in the target direct current control protection device can be acquired, and all the program source codes, executable codes, check codes and the like can be found.
After the executable code stored before the selection is updated, the updated data can be directly replaced by the updated data to update the burning time, or the updated data can be stored in a new data adding mode, so that the rollback of the program version can be conveniently realized by storing a plurality of different executable codes.
On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, the update instruction is specifically:
and updating the target executable code corresponding to the latest burning time.
In particular, the received update instruction for updating the target executable code may be an update instruction for updating the target executable code corresponding to the latest burning time. It can be understood that the target executable code corresponding to the latest burning time is generally the program currently operated by the target dc control protection device, so that an update instruction for updating the target executable code corresponding to the latest burning time can be directly set, and the operation program of the current target dc control protection device can be updated.
On the basis of the above embodiment, the present embodiment further describes and optimizes a technical solution, and specifically, after receiving an update instruction for updating the target executable code, the method further includes:
and (3) carrying out identity verification on the operator, and after the identity verification is passed, entering a step of acquiring a target program source code corresponding to the target executable code from the target direct current control protection equipment.
In order to facilitate management control of the target direct current control protection device and ensure safety of information in the target direct current control protection device, in this embodiment, after receiving an update instruction for updating a target executable code, the identity of an operator is further checked, where the type of identity check may include checking an access password input by the operator, or checking personal biological information such as a fingerprint, a voiceprint, and an iris of the input operator, and determining that the identity check passes when the comparison is consistent by comparing the check information input by the operator with the authentication information stored in advance. And after the identity verification is passed, acquiring target program source codes corresponding to the target executable codes from the target direct current control protection equipment.
It can be seen that the present embodiment can further improve the security in updating the executable code in the target dc control protection device.
