可以考虑将重复的代码抽象成一个函数，然后在需要的地方调用该函数。具体来说，可以把以下部分抽象成一个函数：

LCD_DisString((i%9)+1,  20, (char *)gcszOnOff[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,DBData[i])]);
if (not == 2) {
    if(draw == (i+1)) {
        LCD_DisString_Not((i%9)+1,  20, (char *)gcszOnOff[(int)get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,DBData[i])]);
    }
}

然后可以把其他类似的代码也进行抽象。这样可以大大简化代码，增强可读性。

这段代码可以优化的地方有：

1. 将重复的代码提取出来，避免重复书写。例如，多次调用 `LCD_DisString` 可以提取出来作为一个函数，减少代码重复。

2. 将一些条件语句的判断条件提取出来，避免重复书写。例如，多次使用 `DBData[i]` 的值进行判断，可以将它提取出来，避免重复书写。

3. 使用 switch 语句来替换多个 if-else 语句，使代码更加清晰。

4. 对于 `sprintf(szVal, "%0.3f" , get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,DBData[i]))` 这一行代码，可以考虑使用 snprintf 函数来避免缓冲区溢出。

首先，可以看到在代码中有很多重复的部分，比如调用`get_ActionDZInfo_val`函数、调用`sprintf`函数、调用`LCD_DisString`函数等。我们可以将这些重复的部分抽象成一个函数，减少代码的冗余。

其次，可以将一些常量和字符串存储到数组中，这样可以减少代码中的硬编码，提高可读性和可维护性。

最后，可以使用条件语句合并一些相似的逻辑，减少代码重复。

以下是重构后的代码：

const char* FBS_NAME[] = {"常开", "常闭"};
const char* FBS_MODE_NAME[] = {"标准", "反向"};
const char* ModeName[] = {"单相", "三相"};
