单片机一个定时器多个定时点，为何1小时以上的没响应

最近做一个充电器单片机软件，涉及到用一个定时器设定多个定时器，而且要求其中一个响应后，关闭其他定时器，程序如下，上电跑了以后感觉没工作，请教下哪儿出问题了。
单片机定时器设定1ms溢出一次，中断如下：
oid TIMER1_Rpt(void) interrupt TIMER1_VECTOR
{

static unsigned char i;
i++;
if(i>=5)
{
i=0;
breath_light();
}

if(DELAY300MS_ON)
{
if(++Count.delay_time2 >= SOrder_300ms)
{
Count.delay_time2 = 0;
DELAY300MS_ON    = 0;
   LED_blink();
}
}

if(DELAY500MS_ON)
{
if(++Count.delay_time0 >= SOrder_500ms)
{
Count.delay_time0 = 0;
DELAY500MS_ON    = 0;
Vol_relief(  );
}
}

if(DELAY1S_ON)
{
if(++Count.delay_time1 >= SOrder_1s)
{
Count.delay_time1 = 0;
DELAY1S_ON    = 0;

}
}
  if(FLAG_1HOURHALF ==1)
{
   if(++Count.Order_1min0 >= SOrder_1min)
   {
   Count.Order_1min0 = 0;
   if(++Count.Order_1hour5 >= SOrder_1hour5)
   {
   Count.Order_1hour5 = 0;
   FLAG_1HOURHALF = 0;
   }
   }

}

if(FLAG_2HOUR == 1)
{
   if(++Count.Order_1min0 >= 20000)    //SOrder_1min)
   {
   Count.Order_1min0 = 0;
   if(++Count.Order_2hour >= SOrder_2hour)
   {
   Count.Order_2hour = 0;
   FLAG_2HOUR = 0;
   }
   }
}

if(FLAG_7HOURHALF ==1)
{
   if(++Count.Order_1min0 >= SOrder_1min)
   {
   Count.Order_1min0 = 0;
if(++Count.Order_7hour5 >= SOrder_7hour5)
   {
   Count.Order_7hour5 = 0;
   FLAG_7HOURHALF = 0;
   }
   }
}

主函数部分调用程序如下：

switch(Scharge)
{
case Idle:
........
break;

case pre_Charging:
   /*设定*/
   FLAG_2HOUR = 1;
              .....
   /* if(2hour arrive)  */
         if(FLAG_2HOUR == 0)
         {
RED_LIGHT = 1;
Scharge = Close_charge;
}
         break;

case Charging:
/*7.5hour  set  */
      FLAG_7HOURHALF = 1;
      .....
/*7.5hour arrived*/
      if(FLAG_7HOURHALF == 0)
            {
                     .....
      }
break;
