[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of battery management systems, in particular to a BMS parameter expansion and display system.
[ background ] A method for producing a semiconductor device
Currently, in the technical field of Battery Management Systems (BMS), iterative development work and energy storage product upgrade development work of the same type for the same electric vehicle are common, in the development work, an electrical System and a structural design are common, for example, the capacity of energy storage products, the number and the control principle of master control boxes, the number and the arrangement of Battery boxes, the number of relays, and the like have great differences, and for BMS software development, the differences mainly focus on two aspects of control strategies and parameter expansion. In the process code compiling of parameter extension, not only the data type description, the addition of the structure body, the address macro definition, and the like of the parameter are required, but also the parameter value of the parameter is required to be transmitted through a CAN (Controller Area Network) protocol. However, this process is cumbersome, which in turn makes it very prone to errors.
In addition, the existing display screen realizes the numerical value display and setting of parameters through CAN communication in a host, and the parameter names and descriptions are all in the format of pictures. For example, the "highest cell voltage of 3.5V" displayed on the display screen, wherein only the value of 3.5 is the information sent by the CAN in the BMS, and the rest are pictures which are not changeable. Therefore, if a new parameter name and a parameter value are displayed on the existing display screen, the new parameter name and the parameter value need to be displayed by using additional application software, the process is complex, and a plurality of parameters also need to be added with codes for many times and software compiling work is repeated.
Accordingly, there is a need for a new BMS parameter expansion and display system that overcomes the above-mentioned deficiencies.

In addition, the content displayed at the fixed position of the display screen is not fixed, and can be freely defined in the BMS host without developing the display screen, so that the development period of a software engineer on a new order and a new project is accelerated, and the maintenance and detection of the software engineer on the new order and the new project are facilitated by aftermarket personnel.
[ description of the drawings ]
Fig. 1 is a functional block diagram of a BMS parameter expansion and display system provided in an embodiment of the present invention.
[ detailed description ] A
In order to make the objects, technical solutions and advantageous technical effects of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration only and not by way of limitation.
Please refer to fig. 1, which is a functional block diagram of a BMS parameter expanding and displaying system 99 according to an embodiment of the present invention. The BMS parameter expanding and displaying system 99 includes a BMS host 100 and a display screen 200 communicating with the BMS host 100. Specifically, the BMS host 100 includes a parameter extension module 110, a parameter processing module 120, a parameter transmission module 130, and a parameter reception module 140. The display screen 200 includes a parameter setting module 210 and a parameter display module 220. It is understood that the functional modules may be stored in the memory in the form of a software program and executed by the processor, or may be hardware with a specific function, for example, a chip burned with a specific software program.
The parameter extension module 110 is an interface for adding parameter extensions in the host program of the BMS host 100. Specifically, the parameter extension module 110 adds a set of definitions as undefined parameter names and corresponding variable values to the host program lnner Can. Wherein the default values of the parameters are given to double bytes; the parameter names are less than or equal to 20 characters, and the number of the extension parameters is less than or equal to 16. In this embodiment, the definition is a character type two-dimensional array. Further, the parameter names are set to be unchangeable on the display screen 200 side to prevent the extended parameter names from being modified by mistake.
The parameter processing module 120 is configured to form an extended parameter processing function. The extended parameter processing function is used for copying the characters of extended parameter display group number (ParameterGroup), parameter value (ParameterVal) and parameter name (ParameterName) into the corresponding array of the extended parameter.
The parameter sending module 130 is configured to define a Send processing function of the extended parameter in the CAN. The Send processing function is configured to store 16 sets of parameter information in corresponding IDs, and Send the parameter information to the display screen 200 through the CAN bus. It is understood that the parameter information can be read and displayed by the display screen 200.
The parameter receiving module 140 is used for defining a Receive function of the extended parameter in the CAN. The Receive function is used for detecting whether an information message ID from the display screen 200 exists. If so, the message information is received and assigned to the corresponding parameters, thereby achieving the purpose of modifying the values of the extended parameters through the display screen 200.
The parameter setting module 210 is used to add an extended parameter name, a parameter value, and a setting interface for parameter setting. In this embodiment, the setting interface includes the extended parameter name, the page, the display position, the variable address, the display length, the font size, and the key set in the display screen for the parameter value and the parameter. Specifically, the parameter setting module 210 adds an extended parameter name, a parameter value, and interfaces of setting parameters on a page, a display position, a variable address, a display length, a font size, a key setting, and the like in the display screen through the display screen development software DGUS.
The parameter display module 220 is used to add an address of a variable control and a data transmission code in the User program of the display screen 200 to implement communication with the BMS host 100. When the parameter display module 220 detects the corresponding extended parameter ID and its information, it reads it and displays the extended parameter name and value on the corresponding page and position in the display screen 200; meanwhile, the parameter display module 220 also receives an operation command of a user to implement modification of the parameter values and transmits the modified values to the BMS host 100. In this embodiment, the parameter display module 220 communicates with the internal CAN of the BMS host 100 at a baud rate of 125K.
According to the BMS parameter extension and display system provided by the invention, when important extension parameters in subsequent development work need to be displayed and processed on the display screen 200, complex codes do not need to be written repeatedly to develop programs in the BMS host 100 and programs in the display screen 200, and meanwhile, the setting of the display screen 200 end and the parameter information of the BMS host 100 end can be exchanged and updated. In addition, the content (parameter name, parameter value, parameter setting) displayed at the fixed position of the display screen 200 is not fixed, and can be freely defined in the BMS host 100 without developing the display screen 200, which not only accelerates the development period of a software engineer for a new order and a new project, but also facilitates the maintenance and detection thereof by after-market personnel in the future.
The invention is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the invention is not limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
