Special rate extends the configuration project such as frame or standard frame, data frame or remote frame, frame format and frame type, and CAN bus 20 matches confidence
It ceases for planning that CAN bus 20 acquires specification and the range etc. of data.Further, in one embodiment of the invention,
All first data can be hexadecimal data.
Further, in one embodiment of the invention, the data analysis set-up of CAN bus can also be aobvious including data
Show module 40.Data disaply moudle 40 is used to obtain the display mode of user's selection, and the display mode pair selected according to user
All first data or all second data are shown.Further, in one embodiment of the invention, display mode can
To include: all first data of display, all second data of display and all second data for showing pictorialization.Wherein, aobvious
When showing all first data, it is contemplated that compatible problem, all first data are without any change, in order to professional person
Initial data is analyzed, and convenient for non-professional advanced crowd's study and is used.
It should be noted that all first data of display, all second data of display, can read data in order to user,
And the variation tendency of the second data can be checked to analyze data, such as really in order to user by showing all second data of pictorialization
Determine the information such as extreme value, user can independently select display mode, the data analysis of the CAN bus of the embodiment of the present invention according to demand
Device not only increases the analysis strategy of user, also enhances the analytical effect of user.Further, in a reality of the invention
It applies in example, occurs not conforming to convention when in all second data of all second data or pictorialization that data disaply moudle 40 is shown
Jump when, user can show all first data come when checking that the jump for not conforming to convention occur in the second data pairs by selection
The first data answered, consequently facilitating the reason of analysis generates jump.
Further, in one embodiment of the invention, data disaply moudle 40 may include: submodule of drawing a diagram
41 and display sub-module 42.Wherein, submodule 41 of drawing a diagram is used for using all second data as dependent variable, by CAN bus
The time of 20 progress data acquisitions or the number of all second data are drawn a diagram as independent variable.Display sub-module 42 is for showing
Diagram table.It should be noted that when the independent variable of chart be CAN bus 20 carry out data acquisition time when, can in order to
The size variation of the variation tendency of the second data and the second data in certain time period is checked at family.
Further, in one embodiment of the invention, preset data organizational form can also include: the title of data
(NAME), position, that is, data intercept of the unit (UNIT) of data, the length (LENGTH) of data intercept and data intercept is opened
Beginning position (STARTBIT).In general, CAN bus 20 acquire each message data have one can to determine its class
The data segment of type, the data segment can be 8 16 binary datas, and data, the hereinafter referred to as data segment are the data segment for identification
Frame ID.
Further, in one particular embodiment of the present invention, the data type that user selects is speed (Vehicle_
Speed), data analysis module 30 extracts all vehicle speed datas from the data that CAN bus 20 acquires, according to preset data tissue
All vehicle speed datas are managed for configuration in mode, wherein the frame ID of vehicle speed data is 0x121, and speed calculation formula is y=
0.06875x, speed unit are km/h, and the vehicle speed data start bit of interception is 0, and the vehicle speed data length of interception is 12.Data point
Module 30 is analysed to calculate the vehicle speed data that collected each frame ID of CAN bus 20 is 0x121 all in accordance with speed calculation formula
Speed, such as 12134ms, CAN bus collects vehicle speed data when being 19 00 01 04 10 00 00 AC, then from 0
Start to intercept 12-bit data, i.e. 000110010000=400, then speed is y=0.06875*400=27.5km/h.In turn
All speeds are acquired the time of each vehicle speed data as independent variable as dependent variable, using CAN bus 20 by data disaply moudle 40
Draw figure as shown in Figure 3, wherein ordinate is speed, and abscissa is the time that CAN bus 20 acquires each vehicle speed data.With
It family can be from variation tendency of the speed within each period be found out in Fig. 3 easily, consequently facilitating analyzing certain time period speed
