When being worth the duration of range greater than preset duration, and the temperature is greater than alarm threshold, turns off the equipment power supply；
Wherein, the voltage reasonable value range that voltage input levels deviate equipment refers to that voltage input levels are lower than under the voltage for allowing to input
Limit value or voltage input levels are higher than the upper voltage limit for allowing to input；
Wherein, processing unit is also used to determining that the voltage input levels deviate the voltage reasonable value range of the equipment
Duration is greater than after preset duration, and before turning off the equipment power supply, carries out equipment self-protection；
Wherein, the processing unit, specifically for when determining that the temperature is greater than reasonable threshold value, then being limited according to level of power consumption
The function of each peripheral module of the equipment is opened；Wherein, the reasonable threshold value is less than the alarm threshold；
When the function of each peripheral module of the equipment has all limited unlatching, and the temperature is greater than reasonable threshold value, then according to
The function that important level limits each business module of the equipment is opened；
Power detecting unit is also used to then continue to test the electricity of the equipment when determining the temperature no more than reasonable threshold value
Press input value；
When the function of each business module of the equipment has all limited unlatching and the temperature greater than reasonable threshold value and is not more than
When alarm threshold, then the temperature of the Primary Component or key area in the equipment in power conversion module is continued to test.
7. device as claimed in claim 6, which is characterized in that described device further include: storage unit；The storage unit is used
In after determining that the voltage input levels deviate the voltage reasonable value range of the equipment according to the judgement result, save
Exception information.
