Description
Technical field
The present invention relates to electronic technology field, more particularly to a kind of computing platform low-temperature switch machine method of discrimination is used for
System alarm and shutdown under computer system power-on condition and abnormal temperature are judged at low ambient temperatures.
Background technology
Industry and military environment under, computer system be frequently necessary in subzero less than 30 degree of low temperature environment be switched on and
Work.In order to ensure that various parts can work normally at low ambient temperatures, need to increase heater circuit in circuit-board card,
Each critical component is heated under low temperature environment.Meanwhile temperature monitoring circuit reaches certain in the temperature for judging critical component
Just whole system is allowed to be switched on during threshold value.And when critical component temperature be less than a certain threshold value when, system may abnormal work, this
When, temperature monitoring circuit provides warning information, and computer system is shut down.
Then, the switching on and shutting down condition under accurate judgement computer system low temperature environment is just very crucial, at low ambient temperatures
System alarm and shutdown under computer system power-on condition and abnormal temperature are judged, if it does not, will cause computer
System critical component misoperation at too low temperature leads to not expected abnormal phenomenon.
Invention content
In order to solve problem of the prior art, the present invention provides a kind of computing platform low-temperature switch machine method of discrimination,
For judging system alarm and shutdown under computer system power-on condition and abnormal temperature at low ambient temperatures, department of computer science is avoided
System critical component misoperation at too low temperature, leads to not expected abnormal phenomenon.
The technical solution adopted in the present invention is as follows:
A kind of computing platform low-temperature switch machine method of discrimination, includes the following steps:
A, Complex Programmable Logic Devices and temperature sensor node after the power is turned on, Complex Programmable Logic Devices acquisition node temperature
Degree;
B, when all critical component temperature are above temperature A, power supply chip is enabled, otherwise computing system booting does not allow out
Machine, return to step A continue collecting temperature;
C, after being switched on, Complex Programmable Logic Devices continuous collecting node temperature;
When a certain critical component temperature reports warning message, and start to close less than temperature A less than temperature B, temperature B to host computer
Machine countdown if all critical component temperature are above temperature B, continues collecting temperature, keeps the operation of system normal boot-strap;
If D, countdown reaches setting time, shut down computer.
Setting time is 2 minutes.
When system is in off-mode, if the critical component temperature of computer system is less than temperature A, complex programmable
Logical device suppression system starting-up signal exports.
A kind of computing platform low-temperature switch machine method of discrimination of the present invention, with CPLD(Complex Programmable Logic Devices)As
Monitoring temperature and the processing core of switching on and shutting down control, using temperature sensor as the node of monitoring temperature.When system is in shutdown
During state, if the critical component temperature of computer system is exported less than temperature A, CPLD suppression system starting-up signal, work as key
Part temperatures are higher than temperature A, output system starting-up signal.Meanwhile under the conditions of having been switched on, continue to monitor critical component temperature,
If critical component temperature is less than temperature B(Temperature B<Temperature A), then system core part temperatures exception information is provided, by the information
Host computer is uploaded to, meanwhile, system of shutting down computer after the 2 minutes avoids critical component misoperation from leading to computer system
There is not expected abnormal phenomenon.
Turn-on temperature A and early warning/shutoff temperature B need to meet the condition that temperature B is less than temperature A.It is touched with being similar to Schmidt
The mechanism of device is sent out as switching on and shutting down criterion.On the one hand, can reach to avoid when heater circuit gives off heat with function of environment heat emission
During thermal balance, computer system low temperature environment lower switch machine differentiates abnormal;On the other hand, it when computer system works normally, closes
The temperature of key member should be greater than being equal to turn-on temperature A, if device temperature is reduced to temperature B, can determine whether the work of critical component
Temperature anomaly so as to provide warning information ahead of time and shut down computer, avoids computer system misoperation.
A kind of computing platform low-temperature switch machine method of discrimination of the present invention, is used to judge department of computer science at low ambient temperatures
System alarm and shutdown under system compressor start up condition and abnormal temperature avoid computer system critical component at too low temperature from transporting extremely
Row, leads to not expected abnormal phenomenon.
