Shown, the original state of veneer is defined as normal operation by master control borad, the frame picture S mouth messages for then waiting veneer newly to report
(i.e. frame picture message), parse the message and obtain board type and frame picture sequence number.Judge whether board type changes, if single
Plate Change of types, then illustrate that running state of single plate is inconsistent for board type, and wait the frame picture S mouth messages newly reported, it is no
Then judge whether frame picture sequence number increases；If frame picture sequence number increases, it is normal operation to illustrate running state of single plate, and
The frame picture S mouth messages that newly report are waited, otherwise judge whether that frame picture sequence number diminishes and is not 0；If frame picture sequence number
Diminish and be not 0, then it be operation exception to illustrate running state of single plate, and the frame picture S mouth messages that newly report of wait, is otherwise illustrated
Frame picture sequence number diminishes and is 0, and it is normal operation now to illustrate running state of single plate, and waits the frame picture S mouths newly reported
Message.
That is, veneer application program enables timer timing sends frame picture S mouth messages to master control borad.Master control borad
Control program receives veneer frame and sought ways to return sb.'s kindness after text, parses board type, frame picture sequence number information and is preserved with the last time
Value be compared.If board type changes, judge that veneer state in place is inconsistent for board type；It is if current
Value (i.e. current frame picture sequence number) be more than before value, then judge veneer state in place it is normal；If currency is less than upper
The value once preserved, and value is overflow value 0, then judges that veneer state in place is normal.If currency is less than last preserve
Value, and be not equal to overflow value 0, then judge veneer abnormal state in place.After completing above-mentioned judgement every time, master control borad is preserved
Veneer frame index of the picture number (i.e. frame picture sequence number) be updated to the newest value reported of veneer.
By above-mentioned judgement, if master control borad detects that veneer state in place (i.e. running status) changes, and currently
Be worth for state in place it is normal, it is believed that abnormal restarting occurred for monoboard programme, and veneer collocation information has been lost, it is necessary to immediately
Notice message forwarding module re-issues veneer configuration message, so that it is guaranteed that the configuration information that veneer operation needs can be from extensive
It is multiple.
