Embodiment
Below in conjunction with drawings and Examples, content of the present invention is described in further detail.
The present invention is based on a kind of BMS host computer data record of BMS host computer and the on-the-spot method of reducing of data thereof.
As shown in Figure 1, a kind of BMS host computer data record method preserves many parts of files for different B MS data, comprises the following steps:
S1, the complete message data of record communication channel, save as file one; In the present embodiment, adopt CAN passage as the communication channel of the present embodiment, after host computer one sends reading order, just start to record original CAN message data complete in CAN passage, and this message data is saved as TXT formatted file as raw readings file, be saved in host computer, this raw readings file can carry out sequencing numbers according to time or other quantification manners, can carry out fast finding to it when needing to check.
S2, after receiving unit data, according to the agreement of the historical failure data of particular preset, resolves the data after this reception, and carries out legitimacy detection to this part data.In the process of carrying out legitimacy detection, host computer can be classified to these data, meets the data of specific protocol standard as correct data, and do not meet the data of specific protocol standard as misdata using through legitimacy detection using through legitimacy detection.
S3, this correct data saves as CSV formatted file as file two, is user's visual data, by the display interface that is sent to control system after host computer process for user's viewing; And this this misdata is saved as the BAK formatted file of encryption as file three, this file can't be sent on the display interface of control system by host computer, avoid misleading after user touches misdata and making wrong reaction, this host computer also can be avoided because of error message to produce interface situation that is stuck or warning announcement frequently, improve the friendly that host computer uses.
In this file three, also comprise the numerical value of this misdata, the position mark of corresponding message data and error reason.Such as, when some variable formulated exceeds legal range, this can be exceeded the position mark of some variable place message data of legal range out, and the file one at this message data place is marked, again by this error reason " some variable of formulation exceeds legal range " and above-mentioned label record in file three, so that this error message can extract by commissioning staff smoothly facilitate find problem, and the host computer need not preserving this information as tradition, needing problem one by one again to investigate one time just can problem identificatioin position.
As shown in Figure 2, for a kind of based on above-mentioned BMS host computer data record method produce the on-the-spot method of reducing of data of file, the method uses two sets of data reception mechanisms to receive data, then the data received are sent into parsing module resolves; Wherein first set data receiver mechanism is for receiving the api interface data of conventional CAN device hardware, second sets of data reception mechanism for receive use file one simulated field after the simulated data that produces, finally adopt this second sets of data reception mechanism to receive simulated data for the reduction of data scene.
