Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of the online upgrading method for a controller of the present invention, the method includes the following steps: s1, acquiring a program storage area of the controller, and setting an identification area for setting an identification bit and a first partition, a second partition and a third partition for storing programs corresponding to the controller based on the program storage area, wherein the first partition is used for storing a bootstrap program, the second partition is used for storing a first application program, and the third partition is used for storing a second application program; specifically, a program storage area of the controller is partitioned, wherein the identification area is used for setting an identification bit, the first partition is used for storing a boot program, the boot program is used for driving the controller to execute software upgrading operation, the second partition is used for storing a first application program, namely a main application program, and the controller executes the main application program under normal conditions. The third partition is used for storing a second application program, namely a backup application program, and the controller can execute the backup application program in a special state, such as when the main application program cannot be normally executed. Wherein the backup application may be a factory default setting that may be distinguished from the primary application by a version number.
S2, receiving an upgrading trigger instruction, modifying the identification bit of the identification area to be a first preset value, and guiding the controller to jump to the first partition to execute a guiding program according to the first preset value; when the controller needs to be upgraded, the upgrading can be triggered according to the upgrading triggering instruction. When an upgrade trigger instruction is received, firstly, the identification bit of the identification area is modified to be a first preset value according to the upgrade trigger instruction, and after the controller recognizes that the identification bit is the first preset value, the controller is guided to execute a guiding program of a first partition according to the first preset value, and the upgrading state is entered.
S3, receiving the software to be upgraded through a communication interface; that is, after entering the upgrade state, the trigger controller receives the software package for updating through the communication interface.
S4, updating the second partition according to the software to be upgraded to obtain an updated first application program; specifically, under normal conditions, after receiving a software package, that is, software to be upgraded, the first application program of the second partition may be updated according to the software package, so as to obtain the updated first application program.
S5, checking the updated first application program to confirm whether the first application program is updated successfully, if so, executing S6, and if not, executing S7; s6, modifying the identification bit of the identification area to be a second preset value, guiding the controller to jump to a second partition according to the second preset value to execute the first application program, and executing the step S8; s7, modifying the identification bit of the identification area to be a third preset value, guiding the controller to jump to a third partition according to the third preset value to execute a second application program, and executing the step S8; and S8, ending the upgrading process. Specifically, the updated first application program of the second partition is checked to determine whether the updating process is successful, that is, whether the first application program of the second partition is accurate or can be normally used is determined. Namely, the updating result is judged according to the checking result, and if the checking result does not pass, the updating is considered to be unsuccessful. When the first application program is unsuccessfully updated, the controller modifies the identification bit of the identification area to be a third preset value, and when the identification bit of the identification area is the third preset value, the controller jumps to execute a second application program of a third partition. When the verification result is passed, the updating can be considered to be successful. And when the identification bit of the identification area is the second preset value, the controller jumps to execute the first application program of the second partition. When the main application program is successfully updated, the updated main application program is guided to be executed according to the identification bit, and the whole upgrading process is ended, or the whole response process to the upgrading trigger instruction is completed.
In an embodiment, the method for upgrading a controller online further includes: and S11, setting the default value of the identification bit of the identification area as a second preset value. Namely, the identification position of the identification area corresponding to the controller is set as a second preset value corresponding to the second partition by default, and when the controller works normally, the controller directly jumps to the second partition according to the identification area to execute the main application program.
In an embodiment, the method for upgrading a controller online further includes: s0, preprocessing software to be upgraded to add an identification code and a first check code; in step S5, the verifying the updated first application to determine whether the first application is updated successfully includes: and S51, traversing the second partition to determine whether the identification code can be identified, and if not, judging that the first application program is not updated successfully. In particular, the software to be upgraded may be pre-processed, which may be performed before or after receiving the software through the communication port. And in the preprocessing process of the software to be upgraded, adding an identification code and a first check code in the software to be upgraded. The process of checking the updated first application program may be that, after receiving the software to be upgraded, the second partition is traversed to determine whether the identification code can be identified, and when the identification code is not identified, the first application program in the second partition is considered not to correspond to the software to be upgraded, and the update process is considered to be abnormal, and the first application program is not updated successfully.
On the basis of the above embodiment, step S51 further includes: if yes, go to step S52; s52, acquiring program data of the first application program in the second partition to generate a second check code according to a preset check algorithm; and S53, confirming whether the first check code and the second check code are the same, if so, judging that the first application program is updated successfully, and if not, judging that the first application program is updated unsuccessfully. That is, when the identification code can be identified by traversing the second partition, it cannot directly determine that the first application program of the second partition has been successfully updated, and it is also necessary to check the program data of the first application degree updated in the second partition by a preset check algorithm to obtain the second check code, and obtain the first check code to determine whether the first check code is the same as the second check code. And if the first application program is the same as the software to be upgraded, judging that the updated first application program corresponds to the software to be upgraded, and judging that the first application program of the second partition is successfully updated. If not, the updated first application program does not correspond to the software to be upgraded, and the first application program of the second partition is judged to be unsuccessfully updated.
Further, in step S0, preprocessing the software to be upgraded to add an identification code and a first check code; the method comprises the following steps: and processing the software to be upgraded to generate a BIN file, and sequentially adding an identification code and a first check code at the tail of the BIN file. Specifically, the software to be upgraded may be preprocessed by processing the software to be upgraded into a BIN file, and sequentially adding an identification code and a first check code at the end of the BIN file. The identification code can be customized according to the product. Its length is also set to mean as desired, for example, in one embodiment, 12 bytes in length. It may also set the identification code to correspond to the product characteristics.
In an embodiment, the online upgrading method for the controller further includes pre-storing a preset verification algorithm in the first partition. Specifically, a preset check algorithm may be pre-stored in the first partition, or the preset check algorithm may be invoked to calculate a second check code corresponding to the first application program of the second partition when the first application program of the second partition is checked.
In an embodiment, the method for upgrading a controller online further includes: in the software to be upgraded preprocessing process, a preset verification algorithm is obtained so as to obtain a first verification code according to the preset verification algorithm and the software to be upgraded. That is, it may generate the first check code according to the preset check algorithm in the preprocessing process of the software to be upgraded.
In an embodiment, the identification region is disposed between the first partition and the second partition. That is, the identification area is between the first partition and the second partition, the address is not modified by the update of the first application program, and the address does not affect the operation of other programs. The second partition is used as a storage interval of the first application program and is possibly influenced by program updating, the third partition is used for storing the second application program, namely a backup program, the occupied interval of the third partition can be modified along with the updating of the program, the programs are different, the occupied interval can also be changed, and if the address of the identification area is covered by the enlarged first application program or the enlarged second application program, the guiding effect of the third partition cannot be achieved. In some embodiments, the identification area may also set the end of the third partition, which reserves enough addresses for the third partition to prevent the identification area from being occupied by the contents of the third partition.
As shown in fig. 2, in an embodiment, the method for upgrading a controller online further includes: s31, monitoring communication data of the communication interface when receiving the software to be upgraded, and confirming whether an end mark corresponding to the software to be upgraded is received when the communication data stops; if so, go to step S4, otherwise, go to step S7. Specifically, when the software to be upgraded is received through the communication interface, the communication data of the communication interface is monitored in real time, and when the communication data of the communication interface stops, whether the end mark corresponding to the software to be upgraded is received or not is confirmed. That is, normally, when the communication data of the communication interface stops, the software to be upgraded should be completely received, that is, the corresponding end flag is received. If the communication data is not received within a period of time, but the end mark corresponding to the software to be upgraded is not received at the moment, the software to be upgraded can be judged to be not completely received, and the third partition can be entered to execute the second application program directly according to the processing of the update failure of the first application program. The processing procedure can prevent the controller card from being dead in the boot program and being unable to jump out, namely being crashed, caused by accidents such as power failure, communication line disconnection and the like in the updating process.

When the control board is powered on and reset, reading the data stored in the designated address in the flash, when the stored data is 2, directly jumping to the area B, when the main control board sends an upgrading instruction to the motor control board, after the motor control board receives the upgrading instruction, modifying the data stored in the specific address of the flash into 1, and then jumping to the bootstrap program area (A partition) to enter an upgrading state. After entering the upgrade state, the main control board sends an upgrade package to the motor control board through the serial port, the upgrade package can be received by the main control board from the server, and the motor control board writes the received data into the main application program area (B partition). After data reception, normally, the main application area (partition B) has been updated to a new program, and in order to verify that the program is error-free, the program needs to be verified, and the update process is confirmed according to the verification result. In the checking process, the program upgrade package is preprocessed, a BIN file is generated by a new program, a 12-byte identification code (such as TOPBANDDKSRD) and a check code are added at the tail of the BIN file, the check code is a checking result of all data of the new program, and a generating mode such as CRC32 can be used; when the program is upgraded, after the receiving of the program upgrading packet data is finished, traversing operation is carried out on a main application program area (B partition) until a 12-bit identification code is identified, and if the 12-bit identification code cannot be identified by traversing the whole part B, verification fails; after the 12-bit identification code is identified, recording a check code behind the identification code as a check code 1, and generating the check code by using a check mode during preprocessing of data before the identification code as a check code 2; comparing the check code 1 with the check code 2, if the check codes are the same, judging that the check is successful, and if the check codes are different, judging that the check is failed; after the verification is finished, if the verification is successful, modifying the data stored in the flash designated address into 2 and jumping to a main application program area (B partition); if the verification fails, the data stored in the flash designated address is modified to be 3, the data is jumped to a backup program area (C partition), and finally the upgrading process of the motor control panel is finished.
