Machine.After main frame receives three temperature signals, the uniformity of three temperature signals is differentiated：
1) three temperature signals preserve in rational error range after three temperature signals are averaged；
If 2) in three temperature signals, there is a temperature signal to occur exceeding allowable error scope, main frame will be overproof
Temperature signal is rejected, and monitoring server is sent to after only wherein two temperature signal is averaged；This is continuously being appeared above three times
After individual situation, main frame reports abnormality of temperature sensors information to monitoring server.Corresponding indicator lamp is also turned on, is prompted related
Personnel answer timely processing；
3) if three mutual errors of temperature signal exceed allowable error scope (such situation is more rare), main frame is not
Preserve the temperature signal this time measured (temperature signal is as abnormality processing)；It is main after this situation is continuously appeared above three times
Machine reports abnormality of temperature sensors information to be also turned on corresponding indicator lamp to monitoring server, prompt related personnel timely
Processing；
Thermometric processing is carried out using three temperature measurement modules above, the thermometric occurred due to temperature measurement module self reason can be differentiated
Anomaly, it effectively prevent the abnormal wrong report of thermometric.
