The lithium batteries of the existing electric motorcycles and bicycles are usually matched with a battery management system for monitoring information such as battery service conditions, battery voltages, battery lives, battery temperatures and the like.

For the battery management system, the corresponding hardware devices, including operations, storage, etc., have limited hardware resources. The existing conventional remote upgrading method has the defects, such as: 1) when the fault is upgraded, only the network points can be removed for maintenance; 2) when a new management system itself fails, a failure may be caused.

Therefore, in some specific working scenarios, the existing remote upgrading method has the disadvantage that the key and core function program is easy to malfunction during upgrading, so that the core function program cannot work normally, and even the equipment is damaged.

Detailed Description

The invention is further described below with reference to the accompanying drawings and specific embodiments.

In the present invention, a server is a computer or device that provides and manages network resources on a network; the terminal electronic device may refer to various electronic devices, such as an embedded device, an internet of things device, and the like. Referring to fig. 1, the terminal electronic device 1 is communicably connected to the server 2, and the server 2 shown by a dotted box in the figure indicates that the file server 22 and the query server 21 are not distinguished, that is, the server 2 may be replaced with the file server 22 and the query server 21.

The terminal electronic equipment is provided with an upgrading program and a main program, and the two modules are respectively distributed and stored in corresponding storage spaces.

Example 1

Referring to fig. 2, the remote upgrade method of the present embodiment includes the following steps:

and S10, receiving the upgrade file.

When the terminal electronic equipment normally operates, the main program of the terminal electronic equipment normally operates, and the terminal electronic equipment communicates with the server according to the planned task to search and obtain the upgrade file. The planning task is set as required, and is usually performed regularly in a certain period, for example, 24: 00 establish a communication connection with the server. Specifically, a request is sent to the server, and the requested information includes the current upgrade program, the version information of the main program, and the identity information of the terminal electronic device.

The identity information of the terminal electronic device may generally directly adopt IMEI (international mobile equipment identity), and may be replaced with other feature information or custom information capable of identifying the terminal electronic device if necessary.

The version information of the upgrade program and the main program is usually represented by a version number, and is distinguished according to the version information, for example, the version number corresponding to the current upgrade program is A202108010001, wherein a character "A" represents a file corresponding to the upgrade program; the version number of the corresponding main program is B202108010001, wherein the character "B" indicates the file of the corresponding main program.

And after receiving the request information, the server compares version information of the program file stored in the server with the version information in the request information, and if the version information is consistent, a response containing no new version information is returned to the upgrading program. If the server stores the program file of the new version, whether the blacklist corresponding to the program of the new version contains the identity information of the terminal electronic equipment is further checked, so that the phenomenon that the equipment works and is even damaged due to wrong upgrading is avoided.

If the blacklist contains the identity information of the terminal electronic equipment, the current new version program is not suitable for the terminal electronic equipment, and at the moment, a response containing no new version information is still returned to the upgrading program without upgrading; and if the blacklist does not contain the identity information of the terminal electronic equipment, the current new version program is applicable to the terminal electronic equipment, and an upgradable response is returned to the upgrading program.

There may be different ways when the server returns a response that is scalable. One way is that the server sends the new version of the program file directly to the upgrade program. Another way is to define the aforementioned server as a query server, and configure another file server capable of being connected with the query server in communication besides the query server, where: the query server is used only to store the relevant information of the program files and not to store the program files themselves, which are stored in the file server.

If the current new version program is suitable for the terminal electronic equipment, the following steps are carried out:

the response returned by the query server to the upgrade program contains the relevant information of the program file of the new version, which at least comprises version information, such as A202109010001, corresponding to the program file of the new version;

and the upgrading program sends a request for downloading the corresponding program file to a file server according to the version information in the response.

Preferably, the server segments the program file into a plurality of smaller file segments, the upgrade program performs segmented transmission when downloading the program file, and the upgrade program connects all the file segments into a complete upgrade file after receiving the file segments. In the invention, the upgrading file and the program file of the new version are corresponding concepts, and can be understood as the same pointed object. The size of the file segment is configured according to the type of the communication network and different network environments, and particularly, the size of the file segment is further preferably 1-10 KB for the Internet of things.

S20, if the upgrade file is the program file of the upgrade program, generating a backup file of the current upgrade program; and if the upgrade file is the program file of the main program, generating a backup file of the current main program.

The upgrade program and the backup file of the main program can be stored locally or sent and stored on a server. Preferably, the backup file is stored on the file server.

Preferably, if the upgrade file is a program file of the upgrade program, the upgrade file is stored in a storage space of the upgrade program; and if the upgrade file is the program file of the main program, storing the upgrade file into the storage space of the main program. Therefore, the upgrading efficiency is improved, and the adverse effect of upgrading operation on other files in the same storage space is avoided, such as error, accidental deletion and coverage of a certain file.

And S30, upgrading the upgrading program or the main program according to the upgrading file. The specific upgrading steps are conventional in the art and are not described in detail. The programs of the two modules are independently upgraded, so that the probability of faults caused by upgrading failure is reduced. Especially, the upgrading operation of the upgrading program does not influence the normal operation of the main program of the old version.

And S40, generating an upgrading result, including success or failure.

In addition, the upgrade result may further include related information of the upgrade, such as version information.

Further, if the upgrade fails, rollback is executed according to the corresponding backup file. And restoring the backup file before upgrading to the storage space of the corresponding upgrading program or the main program, and ensuring that the corresponding program can normally run in the old version.

Further, the upgrade result is sent to a server, or in a scheme of distinguishing a query server from a file server, the upgrade result is sent to the query server for archiving.

Further preferably, the main program is a battery management system, so as to improve stability and reliability of the battery management system.
