Abstract
Provided is a BMS upper computer program protection method. The extensive makeup language (XML) is adopted by the upper computer program. An encryption method comprises the steps of secret keys are added to the upper computer program, and the secret keys have interference information which avoids malicious decryption. Due to the fact that secret keys are added, security of BMS is enhanced. Besides, XML which can be extensively marked up is adopted to describe in the upper computer program, automatic switching with dpc files can be achieved, and therefore CANoe can be conveniently used by inside staff. Besides, batch processing and batch interpretation can be carried out on XML files by software, controller area network (CAN) bus are fully used, and high efficient transmission of CAN information is ensured.
Description
Technical field
The present invention relates to a kind of electric automobile BMS host computer improvement technology.
Background technology
Describe at present the BMS function of electric automobile or the usual way of CAN signal and divide at present two large classes:
First kind document description Use Word, Excel are that the document of word, form comes Direct function description, the definition of various CAN signals and function in BMS.Advantage be describe more detailed; Shortcoming is only can as the help document of help or dictionary format, must by manually consulting, can't realize the automatic identification of program.
The .dbc file of Equations of The Second Kind CANoe software is described various CAN signals in BMS with the .dbc file layout.Advantage: the file layout of unified standard, can pass through CANoe software automatic translation.Shortcoming: the form of .dbc file and implication are Open Standard, if use the CAN signal of the non-public character of this document format description mean that in BMS, institute's protocols having may be disclosed, the intellecture property of enterprise are caused great loss.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is a kind of BMS host computer procedure guard method that can effectively protect the BMS host computer procedure can arbitrarily not copy, crack.
In order to solve the problems of the technologies described above, the present invention adopts following scheme to realize:
The guard method of a kind of BMS host computer procedure, this host computer procedure adopts the XML language description, and this encryption method is: add key in host computer procedure, have the interfere information of the malicious decryption of preventing in key.
The present invention has strengthened the security of BMS by adding key.And, host computer procedure of the present invention is because use the XML language of extensibility mark to be described, can realize the automatic conversion with the .dbc file, facilitate the insider to use CANoe, and the XML language file can be carried out batch processing and deciphering by software, take full advantage of the CAN bus, guaranteed the high efficiency of transmission of CAN information.
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with embodiment, the present invention is described in further detail:
Arbitrarily copy use for fear of the BMS host computer procedure; avoid battery and management system technical information thereof to reveal; this enforcement namely designs the guard method of a kind of BMS host computer procedure, and the method adopts the XML language as communications protocol, describes function and the CAN signal of BMS with it.Because the XML language is Markup Language, so this file can be carried out batch processing and deciphering by software, and use host computer procedure to be converted to the .dbc file that CANoe software can be identified to the XML language file, facilitate the internal staff to use CANoe and BMS to carry out communication.
This guard method is for adding key in host computer procedure; XML language file content is encrypted, uses the encryption rule of oneself, in file, only some is real key information to key; other parts are distracters, thereby prevent other people Brute Force key.
The same XML language description with meeting this communication protocol standard of host computer procedure, other host computer procedure that arbitrarily copies can not use; And all need key when opening host computer procedure at every turn.This programme adds cryptographic algorithm in host computer procedure, and after transforming through cryptographic algorithm after the key input, ability and BMS set up the confirmation of shaking hands, and carry out communication.Therefore same client has different host computer procedures hardly, increase client's battery information technical know-how.
To sum up; this programme can realize that different clients has a different host computer procedure; between different clients, host computer procedure can not be general; and do not use the host computer procedure of XML language description cannot use yet; adding the use of key; for BMS and battery increase triple protection, protect as far as possible its information not revealed.
Above-described embodiment is only wherein specific implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these apparent replacement forms all belong to protection scope of the present invention.
Claims (1)
1. BMS host computer procedure guard method is characterized in that, this host computer procedure adopts the XML language description, and this encryption method is: add key in host computer procedure, have the interfere information of the malicious decryption of preventing in key.
