御姬之翼攻略:请问这段程序是什么意思？

void Display() _task_ Monitor{
unsigned char data TempSec;
unsigned char WantShow[4];
IP |=0x01;
while(initOk==0);
while(1){
dog=dog | 0x2;

//告警声音控制
if(((usysparam.gjppara.DeviceState[3]-0x30) & 1)==1){
if(BeepSec>0){
//控制声音
if((State9000 & 0x20)==0x20){
LedSelect=State9000=State9000 & 0xdf;
}else{

}

}
if(TempSec!=g8563_Store[0]){

if(RestoreParam>0) RestoreParam--;

}
SetTimeToStr();

}

}
if((NowShowIndex<4 && myswitch[NowShowIndex].AlmType==1) || (NowShowIndex==4 && mydoor[0].AlmType>0)){

}
}
}else{

ShowTime(1,WantShow);
}
}else{
ShowTime(0,"\0");
}
if(DogSec==nowSec|| dog==7){
if(dog==7){
dog=0;
//喂狗
WDT_CONSTR=0x37;
}else{

}

}

}
}
它主要完成一个什么样的功能呢？各位大虾能否给我说得尽量详细一下呢？
