The scheme has the following problems:

The first system partition (system running partition) and the second system partition (system backup partition) store A101 system software and A100 system software respectively, wherein A100 system software is backup software. When receiving the A102 system software upgrade instruction through OTA, download the A102 system software to the system backup partition to overwrite the A100 system software, and exchange the system running partition with the system backup partition, so the A101 system software becomes stored in the system backup partition. The A102 system software is in the system running partition. Since the A102 system software is found to be abnormal, the A101 system software is run from the system backup partition. When receiving the A103 system software upgrade instruction again, download the A103 system software to the system backup partition again to overwrite the A101 system software, and if the A103 system software is found to be running abnormally at this time, either run the abnormal A103 system software, or switch back to the abnormal The A102 system software cannot guarantee the normal operation of electronic equipment such as robots in any way.

It should be noted that the orientation words such as "inside, outside", "front, rear" and "left and right" in this article are based on the product use state as the reference object. Obviously, the use of the corresponding orientation words protects this scheme. Scope is not intended to be limiting.

Please refer to FIG. 1. FIG. 1 is a flowchart of a system software upgrade method provided by the present invention.

As shown in Figure 1, a system software upgrade method of a robot provided by the present invention is used for OTA upgrade and update of electronic equipment, and the method includes the following steps:

Step 110 , after receiving the system upgrade message, the electronic device backs up the system backup partition to a temporary storage area in the memory. The upgrade message may be implemented by OTA push.

The memory of the electronic device has two system partitions: the system running partition and the system backup partition. The system running partition stores the current system software A101 that the electronic device can currently start normally and run stably. Usually, the electronic device can currently start normally and run stably. latest software version. The system backup partition is used to back up the system software, and stores the system backup software A100 of the electronic device that can start normally and run stably, usually the last software version of the electronic device.

At this time, the system running partition is the current system software A101, and the system backup partition is the system backup software A100.

Step 120, the electronic device downloads the system upgrade software A102 and overwrites the system backup partition with the system upgrade software A102.

After the system upgrade software is downloaded, first perform the software package integrity check, if the software package integrity check passes, it means that the system upgrade software is downloaded completely, write the system upgrade software into the system backup partition, and execute step 130; otherwise, explain the system upgrade software The download of the upgrade software is abnormal, for example, the download of the system upgrade software is incomplete, some files are lost, or the files are damaged, etc. In this case, delete the downloaded system upgrade software, download the system upgrade software again, or exit the system upgrade.

The integrity check of the software package can be realized by conventional methods such as joint verification of file length and MD5. The method of file length verification is to compare whether the size of the downloaded upgrade file is consistent with the original file. The method of MD5 verification is that the server performs MD5 verification on the file, returns the relevant information, and the client downloads the upgrade file and updates the upgrade file. Compare the MD5 generated by the server with the MD5 generated by the server. If the two are consistent, the upgrade file is complete. If they are inconsistent, the upgrade file is incomplete. Delete the downloaded system upgrade software, download the system upgrade software again, or exit the upgrade. Among them, MD5 (Message-Digest Algorithm 5, Message-Digest Algorithm 5) is used to ensure complete and consistent information transmission, and is one of the hash algorithms widely used by computers (also known as digest algorithm, hash algorithm).

At this time, the system running partition is the current system software A101, and the system backup partition is the system upgrade software A102.

In step 130, the system backup partition and the system running partition are switched, and the electronic device automatically restarts the system with the system upgrade software, and performs function simulation verification on the system upgrade software during the process of automatically restarting the system.

At this time, the current system software A102 is in the system running partition, and the system upgrade software A101 is in the system backup partition. The system starts with the system upgrade software A102. If it can start and run normally, it means that the system upgrade software A102 has been upgraded successfully; otherwise, it means The system upgrade software upgrade is abnormal.

The function simulation verification is realized by simulation software, which simulates all the normal functions of the electronic device, and is preset in a fixed position in the memory when the electronic device leaves the factory. Here, the fixed location in the memory refers to a fixed address in the memory.

Step 140, the electronic device clears the temporary storage area or restores the system operating partition from the temporary storage area according to the function simulation verification result of the system upgrade software. The specific process is as follows:

If the system upgrade software A102 has passed all the function simulation verification, it means that all the conventional functions of the electronic equipment can run normally under the new version of the system upgrade software A102, and the system upgrade software A102 has been upgraded successfully, so the system upgrade software A102 is retained. and empty the temporary storage area. At this time, the system running partition is the system upgrade software A102, the system backup partition is the current system software A101 before the upgrade, and subsequent electronic devices will be started through the system upgrade software A102.

If the function of the electronic device is found to be abnormal, it means that the downloaded and installed new version of the system upgrade software A102 is not suitable for the electronic device or conflicts with some hardware of the electronic device, and the system upgrade software A102 fails the function simulation verification. The upgrade of the system upgrade software A102 is unsuccessful, so the system running partition at this time is restored from the temporary storage area (because after downloading the system upgrade software and restarting the system, the system backup partition and the system running partition have been switched, so the system at this time The running partition is the system backup partition before the upgrade), restore the system running partition to the system backup software before the upgrade, and switch the system backup partition and the system running partition again. At this time, the system running partition is the current system software A101 before the upgrade, and the system backup partition is the system backup software A100 before the upgrade. Subsequent electronic devices will be started through the current system software A101 before the upgrade to ensure that the electronic devices can run normally. And the system backup software is kept intact.

In the above method, the function simulation verification function is embedded in the power-on equipment self-check program of the electronic device. The specific implementation method is: when the electronic device leaves the factory, the software for the function simulation verification is preset in the memory of the electronic device. Location, function simulation verification software includes simulation programs for the conventional functions of electronic equipment. Add the address of the fixed location in the memory of the software for functional simulation verification in the POST procedure. In this way, after an automatic system restart, the power-on self-test is performed first. When the power-on equipment self-check program runs to the function simulation verification function, the function simulation verification program is obtained from the fixed position of the memory, and the function simulation verification function is realized by running the function simulation verification program.

In order to make the function simulation verification more rational and avoid the function simulation verification every time the electronic equipment is started, the method of the present invention realizes that the function simulation verification is only performed when the system upgrade software runs for the first time through the upgrade flag bit, and again After startup, function simulation verification is skipped. The specific method is:

If the system upgrade software is successfully written into the system backup partition, the upgrade flag will be set;

If the system upgrade software is successfully upgraded, the upgrade flag will be cleared;

Perform a functional simulation check based on the upgrade flag bits.

That is to say, when the system upgrade software is written into the system backup partition, the upgrade flag bit is set, so after the electronic device is turned on, it will enter the boot device self-check program. Since the upgrade flag bit exists, the function simulation verification will be performed.

When the system upgrade software is successfully started for the first time, that is, the upgrade is successful, the upgrade flag will be cleared. In this way, when the electronic device starts up again, since the upgrade flag is cleared, the power-on device self-check program will skip the function. Simulation verification. That is to say, after the system upgrade software is successfully upgraded, the subsequent electronic device will not perform function simulation verification every time it is started, which saves startup time, improves efficiency, and improves user experience.

In the present invention, the temporary storage area can be automatically cleared when a system shutdown or restart instruction is received, so as to avoid conflicts when writing again.

On the basis of the above method, the present invention also provides a system software upgrade device, comprising:

The backup module is used for backing up the system backup partition to the temporary storage area in the memory after receiving the system software upgrade message. The system running partition stores the current system current software A101 of the electronic device that can start normally and runs stably, and the system The system backup software A100 that can normally start and run stably of the electronic device is stored in the backup.

The download module is used to download the system upgrade software A102 and cover the system operation partition with the system upgrade software A102.

The function simulation verification module is used to perform function simulation verification on the system upgrade software A102 in the process of automatically restarting the system.

The processing module is used to clear the temporary storage area when the system upgrade software A102 passes the function simulation verification; when the system upgrade software A102 fails the function simulation verification, restore the current system running partition from the temporary storage area.

The switching module is used to switch the system backup partition and the system running partition after the system upgrade software A102 covers the system running partition, and issue an automatic restart system command; it is used to switch the system backup partition and the system again when the system upgrade software A102 fails to upgrade. Run the partition and issue an automatic reboot system command.

The device may further include a power-on device self-test module, and the address of the software for performing function simulation verification is added to the power-on device self-test module. The software for function simulation verification is preset in a fixed position in the memory of the electronic device, and the fixed position is the address in the memory of the software for function simulation verification.

The device may further include an upgrade flag bit setting module for:

When the system upgrade software is successfully written into the system backup partition, the upgrade flag is set;

When the system upgrade software is successfully upgraded, the upgrade flag is cleared;

The function simulation verification module performs function simulation verification according to the upgrade flag bit.
