[0111] In a specific example, the ground power system configuration mainly includes power supply configuration, maintenance configuration, non-power supply configuration, and unknown status configuration. Its configuration configuration file is designed as follows:

[0112] int GRDPowerstate(bool g_grdpwr,bool g_grdpwrmaintctr=false,bool gpc=false,bool g_grdpwrreadylgt=true,bool riu2mode=true,int gbeatlosttime=0) / / Get the configuration results of different states of external input and output through the status of the ground power switch, maintenance switch and available light

[0185] {

[0186] cout<<"Input parameter error, use default value:"< <endl;

[0187] cin.clear();

[0188] cin.ignore(1000,'\n');

[0189] }

[0190] cout< <e_apun<<""<<apu_genstart<<""<<e_apuoiltemp<<""<<e_apufire<<""<<gearload<<endl;

[0191] };

[0192] / / Generator teacher station input

[0199] if(!(iss>>e_lmgc_break>>e_lmgcu_break>>

[0200] e_rmgc_break>>e_rmgcu_break>>e_apuc_break>>e_agcu_break))

[0201] {

[0202] cout<<"Input parameter error, use default value:"< <endl;

[0203] cin.clear();

[0204] cin.ignore(1000,'\n');

[0205] }

[0206] cout< <e_lmgc_break<<""<<e_lmgcu_break<<""<<e_rmgc_break<<""<<e_rmgcu_break<<""<<e_apuc_break<<""<<e_agcu_break<<endl;

[0207] };

[0208] …

[0209] }

[0226] int apumode=APUPowerstate(e_apun,e_apuoiltemp,

[0227] riu3mode,e_apufire,riu3beatlosttime,e_apuc_break);

[0228] / / cout<<"apu power status"< <apumode<<endl;

[0229] int lmegnmode=LDCMainPowerstate(e_ln2,e_lenoiltemp,e_lenoilpress,riu5mode,e_lmggfire,riu5beatlosttime,e_lmgc_break);

[0230] / / cout<<"Left main AC power status"< <lmegnmode<<endl;

[0231] int rmegnmode=RDCMainPowerstate(e_rn2,e_renoiltemp,e_renoilpress,riu2mode,e_rmggfire,riu2beatlosttime,e_rmgc_break);
