Referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of a software upgrading method based on an OTA technology according to an embodiment of the present invention, and fig. 2 is a schematic application scenario diagram of the software upgrading method based on the OTA technology according to the embodiment of the present invention; the software upgrading method based on the OTA technology is applied to a software upgrading system based on the OTA technology, the system comprises a server terminal 10 and a client terminal 20, the server terminal 10 is in network connection with the client terminal 20 to realize the transmission of data information, and the software upgrading method based on the OTA technology is executed through application software installed in the client terminal 20 and the server terminal 10; the server 10 is a server device, such as a server built in an enterprise or a government department, for executing a software upgrading method based on the OTA technology to obtain information fed back by the client 20 and sending instructions and encrypted upgrading data to the client 20 to upgrade a software program in the client 20; the client 20 is a terminal device for performing the OTA technology-based software upgrading method to feed back the request information and receive the encrypted upgrade data to upgrade the system software program, the client 20 may be a vehicle-mounted terminal installed in the vehicle, and the client 20 may also be another internet of things terminal similar to the vehicle-mounted terminal, such as a smart speaker, a smart television, and the like. Fig. 2 only illustrates one client 20 and the server 20 for information transmission, and in practical applications, the server 20 may also establish communication connections with multiple clients 10 at the same time to implement data information transmission. As shown in fig. 1, the method includes steps S110 to S210.
S110, if the server side receives the newly added upgrade file package, generating update notification information corresponding to the upgrade file package and sending the update notification information to the client side.
The operation and maintenance personnel can input the upgrade file package to the server side, the newly added upgrade file package is also the newly added upgrade file package, the upgrade file package can be a file package used for upgrading the MCU module in the client side, and the server side can generate corresponding update notification information according to the upgrade file package and broadcast the update notification information to one or more client sides. For example, the server may obtain information such as a program version number, a newly added time, and an operation and maintenance staff code of the upgrade file package, and generate corresponding update notification information according to the obtained information, where the update notification information at least includes the program version number.
And S120, the server side encodes and encrypts the upgrade file packet to obtain corresponding encrypted upgrade data.
In order to improve the transmission efficiency of the upgrade file package, the server side can encode and encrypt the upgrade file package to obtain encrypted upgrade data and then transmit the encrypted upgrade data.
In an embodiment, as shown in fig. 3, step S120 includes sub-steps S121, S122, S123 and S124.
And S121, framing the upgrade file package to obtain corresponding file frames, wherein each file frame contains data information equal to the preset unit data quantity.
Specifically, the server may perform framing processing on the upgrade file package to obtain a plurality of file frames, each file frame may include data information of a preset unit data amount, and one file frame may correspond to one complete information transmission fragment. For example, the preset unit data amount may be 512 bytes or 1024 bytes, and in order to improve the data transmission efficiency of the upgrade file package, a larger unit data amount may be set, so that the data amount sent to the client at each time is correspondingly increased, thereby reducing the overall transmission time of the upgrade file package.
And S122, respectively generating a check code corresponding to each file frame according to a preset check code generation rule.
The check code corresponding to each file frame can be generated according to the check code generation rule, and each file frame corresponds to one check code. For example, each character in the file frame may be summed to obtain a checksum (checksum), the checksum may occupy a length of two characters, and the obtained checksum may be used as a check code corresponding to the file frame.
In other embodiments, the manner of generating the check code may also be that each character in the first file frame is summed to obtain a sum check code as the check code of the file frame, the sum check code of the second file frame and the sum check code of the first file frame are summed, and the obtained result is used as the check code of the second file frame; that is, the sum check code of the file frame and the sum check code of the previous file frame are added and calculated, and the obtained result is used as the check code of the current file frame. When the check code of each file frame is checked after the subsequent client receives data, if the previous file frame is missing, the client check code corresponding to the current file frame cannot be accurately calculated, that is, the check code of the current file frame cannot be checked to pass, so that the missing detection of the file frame is realized in real time, the client can immediately check the integrity of the received file while calculating the check code, and the reliability of the file frame transmission process is further improved.
And S123, adding the check code to the tail corresponding to the file frame to obtain initial upgrading data corresponding to each file frame.
And adding the check code to the end of the file frame corresponding to the check code, namely adding a plurality of characters at the end of the file frame to obtain initial upgrading data corresponding to the file frame. For example, when a checksum of two character lengths is used as the check code, two characters are added at the end of the file frame, and the value of the checksum is added to the positions of the two added characters, so that an initial upgrade data can be obtained for each file frame.
And S124, encrypting the initial upgrading data respectively according to preset encryption rules to obtain corresponding encrypted upgrading data.
And encrypting each initial upgrade data according to the encryption rule to obtain the encrypted upgrade data corresponding to each initial upgrade data. Specifically, the encryption rule may be a COBS encoding encryption rule, a COBS (constant Overhead Byte Stuffing) is a fixed Overhead Byte Stuffing algorithm, the Byte Stuffing is used for processing character sequence codes containing special or reserved characters, an encoded character sequence is generated at the length +1 of an original character sequence through a certain algorithm, a new sequence will not contain the special or reserved characters appearing in the previous sequence, the initial upgrade data is encrypted through the encoding process, and the original information in the data transmission process is ensured not to be leaked due to the lack of few characters in the obtained encrypted upgrade data, so that the security of the encrypted upgrade data in the transmission process is improved.
S130, the client compares and judges the received update notification information with the installed software to obtain a judgment result of whether to upgrade the software.
After receiving the update notification information from the server, the client may compare and determine the update notification information with software installed in the client, specifically, may obtain a program version number in the update notification information, obtain a vehicle-mounted version number of the installed software, and compare and determine the program version number with the vehicle-mounted version number, thereby obtaining a determination result of whether to perform software upgrade.
For example, the program version number is B, the vehicle-mounted version number is a, and if B is greater than a, the version number of the upgrade file package is considered to be higher than the version number of the installed software, that is, the installed software in the client needs to be updated and upgraded, if the update prompt information is displayed in the client, the user only needs to click the client to perform the subsequent updating process; if B is not larger than A, the version number of the upgrade file package is not higher than the version number of the installed software, and the installed software in the client does not need to be updated and upgraded.
And S140, if the judgment result is that the software is upgraded, the client sends an updating request to the server.
If the judgment result is that the software is upgraded, the client can send an update request to the server, wherein the update request is request information for updating the software program in the client. Specifically, if the judgment result is that software is upgraded, the client can directly send an update request to the server; or, if the judgment result is that the software is upgraded, the update prompt information is displayed, and the user sends the update request to the server after clicking and confirming.
S150, if the server side receives the updating request from the client side, the server side sends the encrypted upgrading data to the client side.
And after receiving the updating request from any client, the server side can send the encrypted updating data generated in the steps to the client.
In addition, the management server may send a data erasure command to the corresponding client before sending the encrypted upgrade data to the client. After receiving the data erasing instruction, the client can erase the Flash storage medium so as to erase the data stored in the Flash storage medium.
In one embodiment, as shown in FIG. 4, step S150 includes sub-steps S151 and S152.
S151, obtaining a copy of the encrypted upgrading data, sending the encrypted upgrading data to the client, and obtaining receiving information fed back by the client after sending the encrypted upgrading data; and S152, if receiving information fed back by the client, sequentially obtaining a next part of the encrypted upgrading data and sending the next part of the encrypted upgrading data to the client until all the encrypted upgrading data are sent.
Specifically, since the upgrade file package is split in the above steps to obtain multiple copies of encrypted upgrade data, the server may sequentially obtain the encrypted upgrade data and send the encrypted upgrade data to the client, that is, the server sends the data in the upgrade file package to the client in a frame-by-frame manner.
Waiting for a certain time correspondingly every time when sending a piece of encrypted upgrading data; the client receives a copy of encrypted upgrade data, namely, a copy of successfully received receiving information can be correspondingly fed back to the server, and if the management server receives the receiving information fed back by the client within a preset time (such as 2 seconds), the next copy of encrypted upgrade data is obtained and sent until all encrypted upgrade data are sent; if the management server does not receive the receiving information fed back by the client within the preset time, the management server can repeatedly send the current encrypted upgrading data, and repeatedly send the receiving information which is not fed back by the client for five times, the client is considered to be failed in upgrading, and a restarting instruction can be sent to the client to restart the client.
And S160, the client receives the encrypted upgrading data from the server according to the communication interface in the software version information.
The software version information also comprises communication interfaces, namely data transmission interfaces corresponding to newly-added upgrade file packages, and each upgrade file package can correspond to different communication interfaces so as to isolate transmission paths of different upgrade file packages; the client can sequentially receive a plurality of copies of encrypted upgrading data sent by the server according to the communication interface and store the received encrypted upgrading data into a flash storage medium (flash memory). The client correspondingly feeds back a piece of receiving information to the server end every time the client receives an encrypted upgrading data; meanwhile, the client can correspondingly generate an upgrading progress bar according to the proportion of the received encrypted upgrading data to display in a display module of the client, and a user can master the whole progress of the software upgrading process by looking at the upgrading progress bar displayed in the display module.
S170, the client decrypts the encrypted upgrading data to restore and obtain a corresponding upgrading file package.
After the client end finishes receiving a copy of encrypted upgrading data, the client end can decrypt the received copy of encrypted upgrading data immediately, namely, the client end decrypts the received data while receiving the data; the decryption means that the encrypted upgrade data is restored, and the upgrade file package can be obtained by restoring all the encrypted upgrade data after decryption. In addition, the client can also uniformly decrypt the received encrypted upgrade data after receiving all the encrypted upgrade data.
In one embodiment, as shown in FIG. 5, step S170 includes sub-steps S171 and S172.
S171, decrypting each part of the encrypted upgrading data respectively according to a preset decryption rule to obtain decryption data corresponding to each part of the encrypted upgrading data.
Specifically, the client may decrypt the received encrypted upgrade data according to a decryption rule, where the decryption rule corresponds to the encryption rule, the implementation process of data decryption is an inverse operation process of the data encryption process, and the decrypted data corresponding to each encrypted upgrade data may be obtained through decryption.
And S172, sequentially integrating the decrypted data to restore and obtain a corresponding upgrade file package.
The obtained decrypted data can be sequentially integrated according to the receiving sequence of the encrypted upgrading data, and thus the upgrading file package containing all the data files is finally obtained through restoration. The client can store the obtained upgrade file package into a Flash storage medium.
In an embodiment, as shown in fig. 6, step S170 further includes sub-steps S1721 and S1722.
S1721, generating a client check code corresponding to each decrypted data according to the check code generation rule.
The client check code corresponding to each decrypted data can be generated according to the check code generation rule. For example, the values corresponding to the last two characters in the decrypted data may be removed, and the remaining decrypted data may be summed to obtain a sum check code, where the generated sum check code is the client check code corresponding to the decrypted data, and each decrypted data may correspond to one client check code.
In another embodiment, the sum of the previous-segment characters in the first decrypted data is added to obtain a sum check code as the client-side check code of the decrypted data, the sum of the previous-segment characters in the second decrypted data and the sum of the previous-segment characters in the first decrypted data are added to calculate, and the obtained result is used as the client-side check code of the second decrypted data; that is, the checksum of the decrypted data is added to the checksum of the previous decrypted data, and the result is used as the client-side checksum of the current decrypted data.
S1722, judging whether the client check codes corresponding to the decrypted data are the same as the check codes in the decrypted data so as to obtain a data check result of whether an error occurs or not; and if the data verification result is that no error exists, executing the step of sequentially integrating the decrypted data to restore and obtain the corresponding upgrade file package.
Judging whether the client check code of the decrypted data is the same as the check code contained in the decrypted data or not, and if the client check code of each decrypted data is the same as the check code, obtaining a data check result without errors; and if the client check code of any decrypted data is different from the check code, obtaining a data check result with an error.
If the data verification result is that no error exists, executing the subsequent steps; if the data verification result is error, the encrypted upgrade data corresponding to the decrypted data which is verified to be error can be obtained again; that is, the client can generate a data retransmission request according to the decrypted data with errors in data verification, the server retransmits the corresponding encrypted upgrade data according to the data retransmission request of the client, and the client acquires the corresponding encrypted upgrade data again.
And S180, the server side sends a file packet checking instruction to the client side so as to obtain a checking result fed back by the client side.
After the server side completes sending of all encrypted upgrading data and correspondingly receives the receiving information fed back by the client side, the server side can also send a file package checking instruction to the client side, and the client side can check the obtained upgrading file package according to the file package checking instruction and feed back the obtained corresponding checking result to the server side.
And S190, the client checks the upgrade file package according to the received file package checking instruction, obtains a checking result of whether the upgrade file package passes or not, and feeds the checking result back to the server.
Specifically, the client can verify the obtained upgrade file package according to a file package verification instruction, the file package verification instruction can include information such as the total number of files of the upgrade file package, the data size and the like, and the upgrade file package restored by the client can be verified through the information in the file package verification instruction; the client can acquire the basic information of the upgrade file package obtained by decryption and restoration, and judge whether the basic information is the same as the information in the file package checking instruction, so that the integrity check of the upgrade file package obtained by restoration is realized at the client. If the basic information of the upgrade text packet obtained by the client side is the same as the information in the file packet verification instruction, a verification result that the verification is passed is obtained; otherwise, obtaining the verification result which is not verified.
