优化这段代码 if(i > num - 1) break; isDraw = (not == 2 && (draw == i+1)); if (DBData[i] != RT1064_YS_YYDD && DBData[i] != RT1064KZZ_FC_CHZ ) LCD_DisString((i%LISTOFFSET)+1, 0, gRunPara.gap_ActionDZInfo[gapid][DBData[i]].szName); if (DBData[i] == RT1064KZZ_FC_CHZ) LCD_DisString((i%LISTOFFSET)+1, 0, (char *)"大电流闭锁重合闸"); if (DBData[i] == RT1064_YS_YYDD) LCD_DisString((i%LISTOFFSET)+1, 0, (char *)"重合闸检有压时间"); val = get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,DBData[i]); if( DBData[i] >= RT1064KZZ_GL1_ALM && DBData[i] <= RT1064KZZ_KZHL && DBData[i] != RT1064KZZ_MODE && DBData[i] != RT1064KZZ_UAB_CH && DBData[i] != RT1064KZZ_UBC_CH && DBData[i] != RT1064KZZ_FBS && DBData[i] != RT1064KZZ_FBS_MODE) { (isDraw ? LCD_DisString_Not((i%LISTOFFSET)+1, 20,(char *)gcszOnOff[(int)val]) : LCD_DisString((i%LISTOFFSET)+1, 20,(char *)gcszOnOff[(int)val]) ); } else if(DBData[i] == RT1064KZZ_MODE) { (isDraw ? LCD_DisString_Not((i%LISTOFFSET)+1, 20,(char *)ModeName[(int)val]) : LCD_DisString((i%LISTOFFSET)+1, 20,(char *)ModeName[(int)val]) ); } else if (DBData[i] == RT1064KZZ_FBS || DBData[i] == RT1064KZZ_FBS_MODE ) { (isDraw ?

这段代码可以进行如下优化：

1. 将多个 if 判断语句合并成一个 switch 语句，增加代码的可读性和可维护性；

2. 将重复的代码提取出来，封装成函数，减少代码的冗余度；

3. 使用三目运算符代替 if-else 语句，使代码更简洁。

下面是优化后的代码：

for (int i = 0; i < num; i++) {
    if (i > num - 1) break;
    isDraw = (not == 2 && (draw == i+1));
    int data = DBData[i];
    switch (data) {
        case RT1064_YS_YYDD:
            LCD_DisString((i%LISTOFFSET)+1, 0, (char *)"重合闸检有压时间");
            break;
        case RT1064KZZ_FC_CHZ:
            LCD_DisString((i%LISTOFFSET)+1, 0, (char *)"大电流闭锁重合闸");
            break;
        case RT1064KZZ_MODE:
            (isDraw ? LCD_DisString_Not((i%LISTOFFSET)+1, 20,(char *)ModeName[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data)]) : LCD_DisString((i%LISTOFFSET)+1, 20,(char *)ModeName[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data)]));
            break;
        case RT1064KZZ_FBS:
        case RT1064KZZ_FBS_MODE:
            (isDraw ? LCD_DisString_Not((i%LISTOFFSET)+1, 20,(char *)FBS_NAME[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data)]) : LCD_DisString((i%LISTOFFSET)+1, 20,(char *)FBS_NAME[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data)]));
            break;
        case RT1064KZZ_UAB_CH:
        case RT1064KZZ_UBC_CH:
        case RT1064_DZ_CHZCS:
            sprintf(szVal, "%0.f" , get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data));
            LCD_DisString((i%LISTOFFSET)+1, 19 , szVal);
            if(DBData[i] == RT1064_DZ_CHZCS) LCD_DisString((i%LISTOFFSET)+1, 24, (char *)"次");
            if (isDraw == 1) len = LCD_BitNot(UNIT_PROTECT,UNIT_GAP_RT1064,gapid,DBData[i],i,bit);
            break;
        default:
            if (data >= RT1064KZZ_GL1_ALM && data <= RT1064KZZ_KZHL && data != RT1064KZZ_UAB_CH && data != RT1064KZZ_UBC_CH && data != RT1064KZZ_FBS && data != RT1064KZZ_FBS_MODE) {
                (isDraw ? LCD_DisString_Not((i%LISTOFFSET)+1, 20,(char *)gcszOnOff[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data)]) : LCD_DisString((i%LISTOFFSET)+1, 20,(char *)gcszOnOff[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,data)] ));
            } else {
                LCD_DisString((i%LISTOFFSET)+1, 0, gRunPara.gap_ActionDZInfo[gapid][data].szName);
            }
            break;
    }
}

希望这些优化能够对你有所帮助！
