It is interior.
Fig. 1 is according to one embodiment of the invention method execution flow chart, as shown in Figure 1.
S110 reads row a tail wind pressure and row end cell voltage data；Row a tail wind is pressed and row end cell data include each time
The row a tail wind pressure and row end cell voltage of point；
S120 splices frame head postamble data；Specially there are specific start frame and specific end frame
S130, CRC validation；Specially cyclic redundancy check generator polynomial is：G (X)=X16+X12+X5+1.Verifying content is
The full content that from " message length " to " data " terminates.
" message length " indicates the byte number terminated to " CRC " since " source port code ".Cyclic redundancy check is two words
Section
S140 thens follow the steps S150 if serial ports does not receive byte in 3 seconds；If outlet receives byte in 3 seconds
Then follow the steps S110；Judge whether data receiver is completed by setting time, improves the accuracy of data receiver, avoid
The reception of data is imperfect.
S150 reads wind pressure and voltage curve instruction if sent, thens follow the steps S160；If not occurring to read wind
Pressure and voltage curve instruction then follow the steps S110；
S160, according to protocol analysis data and data cached；Specific start frame and specific end frame are read, and to agreement
It is parsed.Agreement is specially
All time uses 4 byte time standards；
All information bytes, according to high byte preceding, low byte is in rear principle；
All data use HEX formats in the case of no agreement；
It is 16 binary datas, such as 17 mark 0x17；
If data command field is sky, only operational order field, it is not necessarily to operation code, then equipment does not judge subsequent byte；
Two 10H that encounter of all data content fields then remove a 10H.
S170 draws row a tail wind pressure and the data and curves and analyzing failure cause of row end cell；The line if row a tail wind is buckled
The wind pressure numerical value of figure sometime put is more than particular value N1 and is less than particular value N2, then train tail host is faulty, and when to this
Between the failure put analyzed.If the voltage value of the curve graph of row end cell voltage sometime put is more than particular value N3
And it is less than particular value N4, the row end cell at the time point of the abnormal voltage is analyzed, if row end cell occurs and falls off
Situation.
