Middle recovery.After health detection in chip and processing, if chip voltage, electric current, temperature or house dog information are still not
Normally, then exception information is reported to by board health control unit by SPI.
Step S30, after processing is adjusted according to exception information in board health control unit, if chip still have it is different
Often, then the power supply of abnormal chips is cut off, and reports exception information to system health administrative unit.
Detailed process is referring to Fig. 5, it is the flow chart of step S30 in network switching control method provided by the invention.
As shown in figure 5, the step S30 includes:
After processing is adjusted in the exception information that S31, board health control unit receive chip transmission, and retransmit healthy inspection
Request is surveyed to chip；
If S32, detecting that chip still has exception, board health control unit cuts off the power supply of abnormal chips, and leads to
It crosses SPI interface and exception information is reported into system health administrative unit.
Specifically, board health control unit receives the health anomalies information of chip, and is judged, if current electricity
It presses through that low, electric current is excessively high or temperature is excessively high, then executes the active frequency redution operation of board；And retransmit health detection request to
(there is abnormal chip) before in chip, if chip still has exception after board frequency reducing, board health control unit is cut
The power supply of disconnected chip, and exception information is reported to by system health administrative unit by SPI.
Step S40, after processing is adjusted according to chip exception information in system health administrative unit, if board still has
It is abnormal, then the power supply of abnormal board is cut off, and exception information is reported to equipment manager.
Detailed process is referring to Fig. 6, it is the flow chart of step S40 in network switching control method provided by the invention.
As shown in fig. 6, the step S40 includes:
After processing is adjusted in the exception information that S41, system health administrative unit receive chip transmission, and retransmit healthy inspection
Request is surveyed to board；
If S42, detecting that board still has exception, system health administrative unit cuts off the power supply of abnormal board, and leads to
It crosses SPI interface and exception information is reported to equipment manager.
Specifically, system health administrative unit receives the health anomalies information of chip, and is judged, if current electricity
It presses through that low, electric current is excessively high or temperature is excessively high, then executes the active frequency redution operation of system；And retransmit health detection request to
(there is abnormal board) before in board, if board still has exception after system frequency reducing, system health administrative unit is cut
The power supply of disconnected board, and it will be reported to equipment manager extremely.
It is illustrated below with two specific embodiments:
(1) program fleet abnormality detection and processing
