Detailed Description
The present invention is described in further detail with reference to the following examples, but the scope of the present invention is not limited thereto.
The invention relates to a method for detecting remote breakpoint continuous transmission by using electricity, which comprises the following steps.
Step 1: the device side requests firmware information.
In the step 1, the equipment side sends a request, where the request includes the latest update time, version number, and equipment side ID.
In the invention, in fact, matching between the locally recorded information and the push information of the platform side should be required to be strictly consistent, when the source file of the platform side is changed, the device side should re-import and re-download the changed file, and clear the downloaded file part of the device side.
In the invention, the equipment side can actively send the request after detecting the updated information, or send the request after the platform side sends the notice.
In the invention, the latest updating time in the request is corresponding to the version number, thereby reducing the situation of error transmission and saving space.
Step 2: and (3) the platform side acquires the request information, if the request is legal, the platform side returns the acceptance information and carries out the next step, otherwise, the platform side returns the rejection information and returns to the step 1.
In step 2, if the device side ID is a trusted ID and the latest update time of the device side is earlier than the latest update time of the firmware corresponding to the version number, the request is legal.
The acceptance information includes the firmware data volume and the number of fragments.
And step 3: and the equipment side presets a storage space based on the acceptance information.
In the invention, the received information comprises the data volume and the fragment number of the firmware, and the amount of the space required to be reserved and the fragments expected to be received on the equipment side are prompted, so that the subsequent checking is convenient.
And 4, step 4: the platform side processes the firmware data and transmits the processed firmware data to the equipment side based on the convention.
The step 4 comprises the following steps:
step 4.1: the platform side processes the firmware data, fragments the firmware data, and arranges all fragments in sequence;
step 4.2: any one of the fragments is provided with an independent identifier;
in the step 4.2, the independent identifier is the time and version number of the current fragment when the current fragment is updated.
Step 4.3: setting a check character string for each fragment;
in the step 4.3, any check character string is encrypted, and the secret key is appointed.
Step 4.4: and transmitting the processed firmware data to the device side in the form of a plurality of fragments.
In the invention, serial numbers exist among the fragments, the serial numbers refer to the arrangement of the fragments from 0 to n, and n is the total number of the fragments.
In the invention, the independent identification means that although the whole firmware package is transmitted, actually, the update may only occur on some fragments, and the rest fragments are not changed, and the update time and the version number of the fragments are marked, so that a large amount of time and space can be saved for subsequent downloading.
In the invention, the check character string is used for the subsequent comparison check, and the key, namely the encryption logic is appointed.
And 5: if the transmission is not interrupted, the transmission is continued; if transmission interruption exists, judging whether the firmware data has new updating after restarting, if so, returning to the step 1, otherwise, resuming transmission at the breakpoint; until updated complete firmware data is obtained.
In the step 5, if the independent identifier on the fragment is the same as the corresponding fragment which is recorded by the device and updated last time, the fragment is not received, otherwise, the current fragment is received; until all the slices are received.
In the step 5, if the independent identifier on the fragment is the same as the corresponding fragment which is recorded by the device and updated last time, the fragment is not received, otherwise, the current fragment is received; until all the slices are received.
In the invention, breakpoint resuming refers to that transmission is resumed from the interrupted segment.
In the invention, in fact, when the updating time and the version number of the transmitted fragment are consistent with those of the equipment end, the fragment can be skipped over completely without downloading.
In the invention, further, when transmission interruption exists, the equipment terminal is allowed to re-request the firmware information after restarting, but the acquired data needs to be matched with the data recorded by the equipment terminal;
if the upgrade record information recorded locally by the equipment end is completely consistent with the received upgrade information and indicates that no further update exists after disconnection, the equipment end requests the fragment firmware again from the disconnection position until all downloads are completed, and then the step 5 is carried out;
if the newly acquired information such as the firmware version information, the length information or the fragment number is inconsistent with the local record information of the equipment terminal, the updating is indicated after the disconnection, so that the local record information is cleared, the step 1 is returned, and the fragment data is acquired again.
Step 6: and after the equipment side obtains the updated complete firmware data, verifying, if the verification is passed, returning success information, and disconnecting, otherwise, carrying out the next step.
In the present invention, the verification in step 6 is obviously to verify the aforementioned verification string.
And 7: based on the information that the verification fails, the device side requests retransmission of part of the firmware data.
In step 7, the retransmitted part of the firmware data is a plurality of fragments of the firmware data starting from the fragment in which the verification is erroneous.
The number of retransmissions is provided with a threshold.
In the invention, the re-request is delayed after single acquisition failure, but the maximum retransmission number should be set for retransmission, and if the transmission is unsuccessful all the time, the communication relationship between the two ends should be judged.
And 7: and the platform side transmits part of the firmware data to the equipment side based on the convention, and the step 5 is carried out.
In the invention, an equipment side requests firmware information, a platform side returns acceptance information after verifying that the request is legal, the equipment side firstly presets a storage space based on the acceptance information, the platform side transmits processed firmware data to the equipment side based on convention, if transmission interruption occurs, whether updating exists needs to be confirmed when transmission is restarted, if yes, the firmware data returns, otherwise, transmission is continued at a breakpoint, the equipment side returns successful information after obtaining the updated complete firmware data, otherwise, retransmission of partial firmware data is requested based on the information which is not verified, and then only the part which is not successfully transmitted needs to be transmitted and downloaded.
In the upgrading process of the embedded equipment end, after failure occurs, the equipment is restarted, then the fragments of the firmware can be downloaded from the disconnected part again, the new content is ensured to be received when the upgrading is restarted each time, and the downloaded content is continuously kept, so that the problem of breakpoint continuous transmission in the remote upgrading process of the embedded equipment is solved, the upgrading success rate of the embedded equipment is improved, and the embedded equipment end has positive use significance for low power consumption, remote upgrading and configuration issuing of wireless equipment and the like.
