The working condition of the power supply 2 of input interface and output interface transmission is acquired according to the first predetermined period；I.e. CPU board 51 passes through power supply
Monitoring module 522 monitors the state of power supply 2, and the status information of acquisition is exported by the output interface of power supply monitoring module 52
To the input interface of CPU board 51, the working condition for the power supply 2 for obtaining CPU board 51, and execute step S103.
Whether just step S103, CPU board 51 judge the power supply of power supply 2 according to the work state information of the power supply 2 of acquisition
Often.Specifically, CPU board 51 monitors the state of power supply 2 by Power Monitoring Unit 522, and the status information of acquisition is passed through into confession
The output interface of electric monitoring module 52 is output to the input interface of CPU board 51；CPU board 51 judges whether the power supply of power supply 2 is normal.
When power supply 2 powers abnormal, step S104 is executed；When power supply 2 powers normal, step S105 is executed.
Step S104, CPU board 51 execute operation before shutdown.Wherein, depositing such as other processes of ends with system is operated before shutdown
The operation such as disk.And the power supply of rechargeable battery 33 is controlled simultaneously.
Step S105 is executed delay operation (10s).
Step S106, shutdown timing start.Wherein, the timing length of shutdown is set according to practical situation, is mainly
Rechargeable battery 33 can be individually for the loss duration of the power supply of mainboard 50, and timing length is less than the loss that rechargeable battery 33 is powered
When.
Step S107 executes delay operation, and executes step S108.
Step S108, CPU board 51 monitor whether to reach the unused time.If reaching the unused time, S109 is thened follow the steps；If
The unused time is not reached, thens follow the steps S110.
Step S109, shutdown, end of run.
Step S110 acquires I/O interface information by the second predetermined period.Specifically, during rechargeable battery 33 is powered, CPU
Plate 51 acquires the working condition of the power supply 2 of input interface and output interface transmission according to the second predetermined period；I.e. CPU board 51 passes through
Power Monitoring Unit 522 monitors the state of power supply 2, and the status information of acquisition is passed through to the output interface of power supply monitoring module 52
It is output to the input interface of CPU board 51, the working condition for the power supply 2 for obtaining CPU board 51, and execute step S111.
Step S111, CPU board 51 judge whether the power supply of power supply 2 is extensive according to the work state information of the power supply 2 of acquisition
It is multiple.Specifically, CPU board 51 monitors the state of power supply 2 by Power Monitoring Unit 522, and the status information of acquisition is passed through into confession
The output interface of electric monitoring module 52 is output to the input interface of CPU board 51；CPU board 51 judges whether the power supply of power supply 2 restores.
When the power supply of power supply 2 does not restore, then step S107 is continued to execute；When 2 service restoration of power supply, S102 is thened follow the steps.
