when the frame number of the received upgrade version reaches the total frame number, sending a verification instruction to the upgrade chip so that the upgrade chip verifies the upgrade version data stored in the memory chip;
and when the verification is successful, sending an upgrading starting instruction to the upgrading chip so that the upgrading chip can write the upgrading version data onto the main control chip.
Further, the verifying the upgrade version data stored in the memory chip by the upgrade chip includes:
acquiring program data and check codes of an upgraded version from a memory chip;
calculating the program data of the upgrade version according to a preset check algorithm to obtain a calculated check code;
comparing the calculated check code with a check code obtained from a memory chip;
when the calculated check code is consistent with the check code obtained from the memory chip, the check is successful; otherwise, the check fails.
Further, the method may further include:
and if communication interruption occurs when the server issues the upgrade version data, the data request of the current frame is sent to the server all the time until communication is recovered, the data of the current frame is successfully received, and then the data request of the next frame is sent to the server.
Further, the method may further include:
when the server issues the upgrade version data, if the main control chip is powered off, the upgrade instruction can still be detected after the main control chip is powered on again;
the main control chip acquires the frame number N of the received upgrade version from the memory chip, and then continuously sends a data request of N +1 frames to the server so as to receive the rest upgrade version data.
Further, the method may further include: and before inquiring whether an upgrading instruction sent by the server is received, storing the original version data on the main control chip in a memory chip.
Further, the method may further include:
when the upgrading chip upgrades the program on the main control chip, power failure occurs, after power supply is recovered, if the main control chip cannot be started normally, the upgrading chip cannot communicate with the main control chip normally, and after waiting for a specific time, if the upgrading chip still cannot communicate with the main control chip normally, the upgrading chip writes original version data stored in the memory chip onto the main control chip.
In practical use, as shown in fig. 3, after the main control chip is powered on, the original version data on the main control chip is stored in the memory chip, and then the normal control logic is executed, and whether an upgrade instruction issued by the server is received or not is continuously queried in the execution process. After receiving an upgrade instruction, the main control chip acquires the required total request frame number N-max, then starts a frame of one-frame request upgrade data and transfers the data to the memory chip, after the data is received, the main control chip sends an instruction to the upgrade chip to enable the upgrade chip to carry out verification, after the verification success instruction is received, the main control chip sends an upgrade start instruction to the upgrade chip, after the upgrade chip receives the upgrade start instruction, an upgrade version program is programmed to the main control chip, after the programming is completed, the main control chip is started, and the main control chip operates according to the upgraded version.
It should be noted that the upgrade version data issued by the server includes a plurality of items of content, and mainly includes a new version program and a program check code, and when the main control chip obtains each frame of data, each frame of data is analyzed, and the upgrade version data of each frame includes: the main control chip memorizes the program data into a fixed program area in the memory chip and memorizes the check code into a fixed check code area.
It should be noted that, if the communication module is powered off when the server issues the upgrade version data, the main control chip will always perform the request of the current frame until the communication module is powered on again, and the main control chip successfully receives the request of the current frame and then performs the request of the next frame. When the server issues the upgrade version data, if the controller is powered off, after the controller is powered on again, the main control chip still detects the upgrade instruction, the main control chip firstly acquires the frame number N of the received upgrade data from the memory chip, and then continues to receive the issued program data from the N +1 frame data request.
It should be noted that, the memory chip stores the frame number N and memorizes the frame number N at a position fixed by the memory chip, the main control chip updates N in the memory chip every time a frame data is written into the memory chip, the memory chip stores contents divided as shown in fig. 5, and the memory chip is responsible for storing the frame number N, the original version data (i.e., old version program data), the check code of the original version data, the updated version data (i.e., new version program data), the check code of the updated version data, and other memory contents.
After receiving the upgrade version data, if the verification fails, the main control chip ignores the received upgrade version data and continuously inquires whether an upgrade instruction issued by the server is received or not so as to perform remote upgrade operation.
As shown in fig. 4, when the upgrade chip is in the process of programming the program to the main control chip, if the controller is powered off, and after power is restored, the main control chip cannot be started normally, the upgrade chip cannot communicate with the main control chip normally, and after waiting for a period of time, the upgrade chip cannot communicate normally, and the upgrade chip will program the original version data to the main control chip.
In the remote upgrade method described in this embodiment,
(1) in the process of issuing the upgrading program, if the controller or the communication module is powered off, after the controller and the communication module are powered on again, the operation before the power failure is continued, and the program issuing can still be successfully executed.
(2) In the process of programming the upgrading program, if the controller is powered off, after the controller is powered on again, the programming operation is automatically carried out again, and the programming process can still be successfully executed.
The remote upgrading method solves the problem that the upgrading of the program version is influenced by the power failure of the controller or the communication module in the program issuing process, and can improve the reliability of remote upgrading; in addition, the method is suitable for on-line remote upgrading, and the cost of upgrading operation is reduced.
