Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The execution subject of the remote upgrade method according to the embodiment of the present application may be the remote upgrade system provided by the embodiment of the present application, for example, the remote upgrade method provided by the embodiment of the present application may be applied to the remote upgrade system shown in fig. 1. The remote upgrade system includes a wireless gateway 20, an internet of things device 10, and a server 30, where the internet of things device 10 may be a product including both receiving and transmitting hardware, that is, a product having receiving and transmitting hardware capable of performing two-way communication over a two-way communication link, and a user may use the internet of things device 10 to establish communication with the server 30 through the wireless gateway 20 to download installation packages or upgrade program files for obtaining multiple different versions of an application program from the server 30. The internet of things device 10 includes, but is not limited to, a cell phone, tablet computer, notebook computer, smart refrigerator, smart air conditioner. The server 30 may be a stand-alone server 30, or may be a server network or a server cluster of servers 30, including but not limited to a computer, a network host, a single network server, a set of multiple network servers, or a cloud server of multiple servers 30. Wherein the Cloud server is composed of a large number of computers or web servers based on Cloud Computing (Cloud Computing). It will be appreciated by those skilled in the art that the above application scenario is merely one application scenario of the present application, and is not limited to the application scenario of the present application, and it will be appreciated that the remote upgrade system may further include one or more other servers, which are not limited herein.
The internet of things equipment leaves a factory and is provided with IAP and APP, the APP is responsible for downloading the remote upgrade file to the storage peripheral equipment, then restarting, the IAP is responsible for reading out and burning the remote upgrade file of the storage peripheral equipment to the APP address, and the original APP is covered. The remote upgrade file is operated twice, the possibility of burning failure is increased, meanwhile, the content which is burnt into the APP address is not compared with the content which is actually required to be burnt, the correctness of the content in the burning process cannot be ensured, and the possibility of burning failure is further increased.
In order to solve the above-mentioned problems, the following begins to describe the remote upgrade method provided by the embodiment of the present application, and referring to fig. 2, fig. 2 is a schematic flow chart of the remote upgrade method provided by the embodiment of the present application. It should be noted that although a logical order is illustrated in the flowchart of fig. 2 or other figures, in some cases the steps illustrated or described may be performed in a different order than shown in the figures. The remote upgrading method provided by the embodiment of the application is applied to the Internet of things equipment, the Internet of things equipment stores a switching control program, a first application program and a second application program which is the same as the first application program in mirror image, the storage addresses of the first application program and the second application program are different, and the remote upgrading method comprises the steps S100-500, and specifically comprises the following steps:
s100, starting to operate the switching control program after power-on, and loading and operating the first application program through the switching control program and the zone bit;
s200, if a remote upgrading instruction is received, analyzing and obtaining a downloading address and a verification check code address corresponding to the second application program according to the remote upgrading instruction;
s300, downloading and obtaining an upgrade program file corresponding to the second application program according to the download address, burning the upgrade program file to a storage address corresponding to the second application program, and obtaining a calculation check code corresponding to the second application program;
s400, judging whether the upgrade program file is the same as the burning content read from the storage address, and comparing whether the verification check code is the same as the calculation check code;
s500, if the upgrade program file is the same as the burning content and the verification code is the same as the calculation verification code, determining that the upgrade of the second application program is successful.
Specifically, in the present application, a first application refers to one of two mirrored applications that has been successfully upgraded last time, and a second application refers to another one of the two mirrored applications that has not been successfully upgraded last time or has not been upgraded last time, that is, the second application is one of the two mirrored applications that is to be upgraded last time.
In an embodiment of the application, the identifier is used as a symbol indicating that the upgrade of the application program is successful in different batches, i.e. the identifiers for remote upgrades of the same application program in different batches are different. If the specified staff has an unreliability factor such as epidemic situation or business trip, and needs to remotely work in the outside or at home, the specified staff only needs to use the internet of things device 10 to send a remote upgrade instruction to the server 30 to obtain corresponding upgrade information, where the upgrade information includes a download address and a verification code corresponding to the first application program.
The storage addresses of the switching control program and the first application program are different from those of the second application program. For example, flash is divided into 3 blocks, for example, flash address is 0x00000000-0x3fffff, switch_app (i.e., the switching control program of the present application) has a memory address of 0x00000000, app1 (i.e., the first application program of the present application) has a memory address of 0x10000000, and app2 (i.e., the second application program of the present application) has a memory address of 0x20000000. The system is powered on and defaults to start running from the address 0x00000000 address, namely, the default runs the switch_APP first, and the switch_APP decides to jump to the APP (namely, APP1 or APP2, the first default is APP 1) which is successfully upgraded last time currently according to the recorded flag bit.
The application burns the upgrade program file corresponding to the first application program obtained by downloading into the storage address corresponding to the second application program mirrored by the first application program, judges whether the burnt content corresponding to the first application program and read from the storage address corresponding to the second application program is the same, and determines that the upgrade of the first application program is successful if the upgrade program file is the same as the burnt content. If the download burning is not the same, the first application program to be upgraded is ensured to be burnt correctly, so that the success of remote upgrading of the Internet of things equipment is ensured, and the reliability and safety of remote upgrading are improved.
In some embodiments, the obtaining the calculated check code corresponding to the second application program includes the steps of:
and calculating according to the recorded content to obtain a calculation check code corresponding to the second application program.
Specifically, the content of the program recorded in the storage address of the second application program in the internet of things device is known, so that the calculation check code can be calculated according to the content of the program recorded in the storage address of the second application program by adopting the same algorithm as that used for generating the verification check code. That is, the algorithm of the verification check code for the second application program generated by the server during the same upgrade operation is the same as the algorithm of the calculation check code for the second application program generated by the internet of things device during the same upgrade operation. In this way, the same content can be ensured to generate the same check code by adopting the same algorithm, otherwise, if different contents adopt the same algorithm, the generated check codes are different.
S440, if the verification check code is different from the calculation check code, determining that the second application program fails to upgrade, and downloading according to the download address to obtain the upgrade program file for burning.
Specifically, the internet of things device may read upgrade information through the URL upgrade interface, where the upgrade information is encryption information. If the upgrade is needed, the remote upgrade instruction is decrypted according to the returned remote upgrade instruction, and the download address of the corresponding upgrade program file and the verification check code corresponding to the file are analyzed. If the currently running APP is APP1, the APP1 downloads an upgrade file to an APP2 address to cover the original APP2; if APP2 is currently running, the original APP1 is covered by the APP2 with the upgrade file.
The server and the internet of things device pre-store the same encryption algorithm for the same application program, namely, the encryption algorithms used for different application program servers and the internet of things device are the same, and certainly, the encryption algorithms used for different application program servers and the internet of things device are different, so that after the internet of things device obtains a remote upgrading instruction, the remote upgrading instruction can be analyzed to obtain a corresponding verification code, the internet of things device reads data from a storage address of a second application program to obtain a burnt content, the internet of things device uses the pre-stored encryption algorithm to encrypt and calculate the burnt content to obtain a calculation check code, and then the internet of things device compares the analyzed verification check code with the calculation check code. The verification check code is a code generated by the server according to the upgrade program file while the Internet of things equipment acquires the upgrade program file. If the verification check code is different from the calculation check code, the fact that the upgrade program file received by the Internet of things equipment is in tampering risk or in error is indicated, and the Internet of things equipment can download and obtain the upgrade program file again according to the download address for burning. Otherwise, if the verification check code is the same as the calculation check code, the internet of things device can determine that the upgrade program file is the same as the burning content, which means that the internet of things device successfully downloads and upgrades the first application program.
In some embodiments, the encryption algorithm may include a hash algorithm, a message-digest algorithm (MD 5 algorithm for short), a secure hash algorithm (Secure Hash Algorithm SHA algorithm for short).
It should be noted that, if the verification check code is different from the calculation check code, the internet of things device may further download the burning attempt 3 times again, if still fails, stop the remote upgrade, report the reason of the upgrade failure to the server 30 through the URL interface, and check the correctness of the upgrade file by the platform operator and resend the remote upgrade instruction. Therefore, the remote upgrade method can be used for re-upgrading under the condition that the platform operator issues the upgrade program file which is not matched with the corresponding check code, or under the condition that the upgrade program file is illegally tampered, so that the success rate of remote upgrade is improved.
In some embodiments, the determining that the second application upgrade was successful includes the steps of:
and updating and restarting the flag bit, wherein the updated flag bit indicates that the second application program is loaded and operated after the next power-on starting.
In some embodiments, the remote upgrade method further comprises:
after upgrading from a current version to an updated version, monitoring whether the first application program or the second application program runs abnormally or not through the switching control program, and respectively counting the running failure times of the running abnormality corresponding to the first application program or the second application program;
and if the operation failure times reach a preset time threshold, switching and operating the first application program or the second application program corresponding to the current version through the switching control program.
Specifically, the data of the operation failure times of the first application program is recorded in another storage area different from the storage address of the first application program and the storage address of the second application program, the data of the operation failure times of the second application program is recorded in another storage area different from the storage address of the first application program and the storage address of the second application program, the operation failure times of the operation abnormality corresponding to the first application program and the second application program are prevented from being covered, the error probability of the available first application program or the second application program is caused to switch operation, the operation failure probability of switching operation is reduced, and the application upgrading is performed under the condition that the use of the Internet of things equipment is not affected.
When the Internet of things equipment leaves a factory, the firmware downloads three program firmware, namely switch_APP, APP1 and APP2. The switch_app will be responsible for switching the APP that should be running according to the corresponding flag bit. The functions of the APP1 and the APP2 are identical, are the APP which is operated for a long time in the normal working state of the equipment, and can be mutually used as backups for the APP operation failure. When the internet of things device is powered on, after the internet of things device runs from the switch_APP, the internet of things device is switched to APP1 or APP2 according to the corresponding zone bit, and APP1 is switched by default for the first time. After the remote upgrading instruction is issued, the downloading address of the program file and the verification MD5 code of the program are analyzed according to the corresponding instruction. According to the download address, the APP1 downloads and records the remote issuing program file into the APP2 address, the recorded content is read out after each recording and is compared with the content to be recorded, if the content is inconsistent, the recording is repeated, and the recording process is ensured to be correct.
The APP1 calculates MD5 of the recorded content, if the calculated MD5 value is inconsistent with the MD5 obtained through remote instruction analysis, upgrading fails, and the switch_APP continues to operate the APP1; if the result is consistent, indicating that the upgrading is successful, writing a corresponding flag bit to indicate that APP2 is to be switched next time, and restarting the Internet of things equipment. After restarting the Internet of things equipment, entering a switch_APP program, switching the APP2 by the switch_APP according to the flag bit written into the APP2 successfully updated, and normally running the APP2 at the moment, so that the upgrading is successful.
Because the switch_APP program has a watchdog mechanism, whether the running APP program runs normally or not can be automatically monitored, when an incorrect remote upgrade file is given out by manual misoperation, and after the remote upgrade file is burnt into an APP2 address by the Internet of things equipment, the APP2 running abnormally can be triggered at the moment, and when the running failure times reach a preset frequency threshold, the switch_APP can be automatically switched back to the APP1 capable of running normally, so that the running stability of the Internet of things equipment is ensured. When the operation failure times reach a preset time threshold, the switch_APP can be automatically switched back to the APP1 which can be normally operated to indicate that the APP1 fails to update from the version 1 to the version 2, an upgrading failure result is reported to a server by the currently operated APP, and a success result is reported by the APP operated after upgrading, so that a background operator knows whether the equipment is successfully upgraded and decides whether the equipment needs to be upgraded again or not, and if the equipment needs to be upgraded again, the operation failure times can be cleared and monitored and counted again.
In the application, the switch_APP can record the accumulated operation failure times (the times can be set) for the APP1 and the APP2 respectively, and can Switch to another APP when the accumulated operation failure times exceed a certain number. For example, the number of operation failures refers to the cumulative number of operation failures of version 2 of APP2 after the APP1 is upgraded from version 1 to version 2. If the version 2 program is an error file or has a problem, the operation failure times are accumulated every time, if the operation failure times are exceeded, the switch_APP does not attempt to operate the version 2 any more, and the operation is returned to the APP1 before updating.
The application preferably upgrades the first application program and the second application program in the same internet of things device alternately through the switching control program, so that the version of the first application program and the version of the second application program in the same internet of things device differ by one version.
For example, the current version number of APP1 is V2, the current version number of APP2 is V3, at this time, the internet of things device operates APP2 of the latest version, that is, APP2 of the V3 version, when version upgrade is required, APP1 is upgraded from V2 to V4 by using the process of the present application, after the success of the upgrade is confirmed, the internet of things device operates APP1 of the latest version, that is, APP1 of the V4 version by switching the control program, when version upgrade is required again, APP2 is upgraded from V3 to V5 by using the process of the present application, and the like, so that the number of times of upgrading the internet of things device can be reduced, and the success rate of the upgrade is improved.
When the field read after writing is inconsistent with the field actually required to be written in a certain writing, the method and the device can re-write at the moment, so that the correct content is successfully written, the success of remote upgrading of the Internet of things equipment is ensured, and the reliability and the safety of the remote upgrading are improved. According to the method, when the error file is updated remotely by the Internet of things equipment caused by manual misoperation, the Internet of things equipment can be actively switched to the other APP capable of normally operating after the operation failure is monitored, so that the operation stability of the Internet of things equipment is ensured.
