Description
Technical field
The present invention relates to a kind of automobile instrument road test data record methods.
Background technique
Current automobile instrument is substantially the validity for needing that certain functions are verified by acquisition proving ground test data.
Traditional recording method is that the supplier of instrument is needed to be equipped with engineer, follows proving ground test and records road test data, then into
Row analysis, not only takes manpower and financial resources in this way, increases the development cost of product, and will lead to partial data not in time
Record, in addition, hand-kept data cannot guarantee that the accuracy of data.
Summary of the invention
Above-mentioned in order to solve, the present invention provides a kind of design scheme of automobile instrument road test data record method.
A kind of automobile instrument road test data record method, comprising the following steps:
S1, memory space data dump step: before memory space start recording data, host computer send clearance order to
Instrument, instrument program is by the data dump in reserved non-volatile storage space；S2, data detecting step: instrument is according to program
In preset record rule detect whether to need to record data, be to enter step S3, otherwise continue to execute step S2；S3, number
According to recording step: instrument writes function according to non-volatile storage space, and the storage of data that needs store non-volatile is deposited to reserved
It stores up in space；S4, data reading step: after the completion of road test, the instrument in road test is fetched, host computer sends to instrument and reads
Data in reserved non-volatile storage space are sent to host computer by instruction, instrument program, and host computer is according to default storage lattice
Formula is parsed.
The S1 is specifically includes the following steps: S11, instrument receive clear command；S22, gauge internal are non-by what is reserved
The specified system number covering of the data segment of volatile memory space；S12, after instrument powers on, using specified system number positioning from
Designated position start recording data.
The step S2 is specifically included: a global variable being arranged in a program, judges whether to store according to design variables value
Data.
The step S3 is specifically included: S31, creating specified cycle detection function；S32, periodic function start to detect program
The global variable of middle setting；S33, when detect global variable be design variables value when, data are deposited according to default storage format
It stores up to reserved non-volatile storage space.
In conclusion the invention has the following advantages: (1) can utilize the remaining non-volatile storage space of instrument,
The important road test data of instrument are stored directly in the space, do not need designer's proving ground test record data；(2) it can reduce
Development cost, and guarantee the timeliness and validity of data, easy to operate, realization is conveniently.
Detailed description of the invention
Fig. 1 is a kind of implementation process schematic diagram of automobile instrument road test data record method of the present invention.
Specific embodiment
In order to allow those skilled in the art that can be best understood from technical solution of the present invention, with reference to the accompanying drawing to this
Invention is further elaborated.
As shown in Figure 1, present invention discloses a kind of automobile instrument road test data record methods, comprising the following steps:
S1, memory space data dump step: before memory space start recording data, host computer send clearance order to
Instrument, instrument program is by the data dump in reserved non-volatile storage space；S2, data detecting step: instrument is according to program
In preset record rule detect whether to need to record data, be to enter step S3, otherwise continue to execute step S2；S3, number
According to recording step: instrument program writes function according to non-volatile storage space, the data storage that needs are stored to it is reserved it is non-easily
It loses in memory space；S4, data reading step: after the completion of road test, the instrument in road test is fetched, host computer sends to instrument and reads
Data in reserved non-volatile storage space are sent to host computer by instruction fetch, instrument program, and host computer is according to default storage
Format is parsed.
Before memory space start recording data, instrument receives clear command, and gauge internal non-volatile is deposited reserved
The data segment for storing up space is covered with specified system number；After instrument powers on, positioned using specified system number from specific bit
Set start recording data.
In order to guarantee that the logging modle program is independently opened with the normal application program module of instrument, reduce to the normal journey of instrument
The interference of sequence can use following methods: a global variable being arranged in a program, judges whether to store according to design variables value
Data.Variate-value is set to 1 with regard to the place of the storing data here oneself thinking that program is run to by if desired storing data.
Specified cycle detection function is created by the operating system of gauge internal；Periodic function starts to detect to be set in program
Global variable；When detecting global variable value is preset value, data are stored according to default storage format to reserved non-
In volatile memory space.
The present embodiment is more excellent embodiment of the invention, and the part not being described in detail is all made of well known maturation
Technology.It should be noted that without deviating from the spirit and substance of the present invention, those skilled in the art work as can
Various corresponding changes and modifications are made according to the present invention, but these change and modification all should belong to right appended by the present invention and want
The protection scope asked.
Claims (3)
1. a kind of automobile instrument road test data record method, which comprises the following steps:
