The memory space of data storage is demonstrate,proved, it is by the file before being automatically deleted 1 week, i.e. T0For one week.
T described above1、t2And T0Temporal information through RTC control units read.
Cause to deposit by mistake to prevent from receiving wrong data, receive after new data, new number is judged according to given protocol
According to whether memory requirement is met, the data for meeting memory requirement are then temporarily put into data buffer area, do not meet the data of memory requirement
Then abandon.The given protocol includes data communication frame ID, ID numbers, frame type, data length etc..The setting of given protocol is not
This mode is confined to, the protocol type of other manner according to data characteristicses, can be also set.Fixed memory medium SD card 3 can be with
It is formatted when needing, microcontroller 1 is received after formatting commands, processing will be formatted to SD card 3.
In order to realize the download function of data storage, microcontroller 1 can be by data downloading management unit by fixed storage
Data duplication in medium SD card 3 in certain time period is into on-fixed storage medium USB flash disk, and the wherein period includes initial time
And deadline, can manually it set or for default time period.For example, by display screen set data to be downloaded initial time and
End time, the command reception processing unit of microcontroller 1 notifies that data downloading management unit enters number after the instruction is received
According to duplication SBR.On-fixed storage medium control unit is detected after USB flash disk access, notifies data downloading management unit
Into data duplication state, the file inquired about one by one in SD card 3 will meet period starting and copy to U by desired file
Disk.During without display screen setting command, the period is downloaded for acquiescence, for example, can be nearest 3 days.
In addition to more than, microcontroller 1 can also coordinate the parameter modification for carrying out mobile unit.Touch screen display can be passed through
Parameter modification instruction, and parameter value are assigned, modification parameter command is mainly used when technical staff debugs, and display screen is being sent
When " modification parameter " is ordered, while sending the corresponding offset of parameter and desired value, microcontroller is received institute after the order
Some information is sent by CAN interface, to notify that mobile unit changes parameter on request.Specific parameter is depended on
Actual items, such as charger and auxiliary power supply system parameter are voltage, electric current, and axle temperature monitoring system parameter is temperature, pyrotechnics
Warning system parameter is smokescope.
