When user selects to download data from serial ports, startup processes the intervalometer of data, the data received is stored, and carries out condition adjudgement according to received data；
Judge whether to meet prefix requirement, after success, be further continued for carrying out next step condition adjudgement, until verifying successfully, when, after the frame number receiving setting, the data that different processes receive being stored as different files.
Further, when data all finish receiving, automatic jump to the display interface of correspondence.
Further, described file is dri file.
Instant invention overcomes the common problems such as current and writing function module communication:
1, in the process that data are downloaded, adopt status mechanism, solve the problem that speed of download is made mistakes slowly and easily.
2, after analyzing, data store in the way of trip file, can obtain the data showing each period flexibly.
3, conventional software can analytical data amount few and display interface is dumb, not humane, this software can analyze and show substantial amounts of vehicle data, up to 280 battery informations.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 and Fig. 2 is the part interface sectional drawing of invention software；
Fig. 3 is the data analysing method flow chart based on CAN memory module of one embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into the scope of protection of the invention.
Fig. 1 illustrates: these part data include speed, traction fault, 15KwU/V/W cross streams voltage, 15KwU/V/W cross streams electric current, power failure, feedback current line limit value etc..
Fig. 2 is the battery information display interface sectional drawing of the software of the present invention；
Fig. 2 illustrates: as it can be seen, battery information can be checked by two ways, one is by selecting different trip file, carrying out video data；Two is by setting the time needing to check, showing run-length data.These part data can also be passed through EXCEL derivation and check.This part packet is containing 280 battery pack informations, and the information of 20 kinds of analog quantity numerical value such as traction electric machine temperature, driving inverter temperature and 18 quantity of states.This part, data rich, data volume is big, processes and adopts multiple threads, it is prevented that page deadlock phenomenon.
Fig. 3 is the data analysing method flow chart based on CAN memory module of one embodiment of the invention；The service data of electric automobile is stored in CAN memory module, is downloaded by RS232 serial ports or USB port, is shown vehicle operation data, and described data analysing method comprises the following steps:
When receiving the order downloading data, carry out serial ports loading, it is judged that whether serial ports is occupied, as occupied in not having, open each thread receiving and processing data；
When user selects to download data from serial ports, startup processes the intervalometer of data, the data received is stored, and carries out condition adjudgement according to received data；
Judge whether to meet prefix requirement, after success, be further continued for carrying out next step condition adjudgement, until verifying successfully, when, after the frame number receiving setting, the data that different processes receive being stored as different files (as being dri file).
Wherein, the return file in Fig. 3 is environ (return function) .dat file, and index file is index (index) .dat file.
Further, when data all finish receiving, automatic jump to the display interface of correspondence.
Above-mentioned downloading process is safe and accurate, quick, and the data of storage can be taked encryption.When display, just it is decrypted process.Increase the safety of its archive..
Above-described embodiment adopts serial port, it is possible in real time by the running status of serial acquisition vehicle.Adopting Indexing Mechanism, carry out the download of different pieces of information, then the mode to the data acquisition state machine of transmission, carries out sequential processing to different conditions, finally all data is being carried out byte verification, can be stored by the data verified.
Meanwhile, the file of each storage all represents different strokes；Distinguished the data of each period by trip file, and store it in information of vehicles in.And the data at Downloadable different time interval store respectively.
Adopt USB port download scenarios (being equivalent to off-line download), may finally check, by the software of PC, the data resolved after downloading.Agreement is flexible, and by the verification mode of security word, the data at different time interval divide, and carries out dissection process and storage respectively.
Additionally, the present invention may also display figure table function, adopt the data of the form display transmission of form.Time and numerical value including running data.Analysis to concrete numerical value, according to after the message protocol of each quantity of state and corresponding resolution and threshold process, just can need to display.Data volume is big, analyzes precisely, according to different requirements, can show different precision.
