style No3 fill:#ffebee
|
||||
style No4 fill:#ffebee
|
||||
```
|
||||
|
||||
#### 检测条件
|
||||
|
||||
```
|
||||
条件1: 法兰前缀的第3位字符 = 'P'
|
||||
例如: FBP-xxx, FCP-xxx, FDP-xxx
|
||||
|
||||
条件2: 表头包含 'F6AP' 或 'F6BP'
|
||||
例如: xxx.F6AP.xxx, xxx.F6BP.xxx
|
||||
|
||||
满足任一条件即为喷涂产品
|
||||
```
|
||||
|
||||
#### 代码实现
|
||||
|
||||
```vba
|
||||
Private Function IsSprayProduct(flange As String, head As String) As Boolean
|
||||
' Check 1: Flange starts with F and 3rd character is P (e.g., FBP, FCP)
|
||||
If flange <> "" And Len(flange) >= 3 Then
|
||||
If Left(flange, 1) = "F" And Mid(flange, 3, 1) = "P" Then
|
||||
IsSprayProduct = True
|
||||
Exit Function
|
||||
End If
|
||||
End If
|
||||
|
||||
' Check 2: Head contains 'F6AP' or 'F6BP'
|
||||
If InStr(head, "F6AP") > 0 Or InStr(head, "F6BP") > 0 Then
|
||||
IsSprayProduct = True
|
||||
Exit Function
|
||||
End If
|
||||
|

IsSprayProduct = False
|
||||
End Function

```
|
||||
|
||||
#### 检测条件
|
||||
|
||||
```
|
||||
条件: 表头包含 'F6A' 或 'F6B'
|
||||
例如: xxx.F6A.xxx, xxx.F6B.xxx
|
||||
|
||||
注意: 喷涂变体 (F6AP, F6BP) 已在 IsSprayProduct 中处理
|
||||
```
|
||||
|
||||
#### 代码实现
|
||||
|
||||
```vba
|
||||
Private Function IsSanitary(head As String) As Boolean
|
||||
' Contains 'F6A' or 'F6B' (but not spray variants)
|
||||
' Note: Spray variants (F6AP, F6BP) are already caught by IsSprayProduct
|
||||
If InStr(head, "F6A") > 0 Or InStr(head, "F6B") > 0 Then
|
||||
IsSanitary = True
|
||||
Else
|
||||
IsSanitary = False
|
||||
End If
|
||||
End Function

## 优先级设计原理
|
||||
|
||||
```mermaid
|
||||
graph LR
|
||||
subgraph Priority["分类优先级 高→低"]
|
||||
P1[1. 喷涂产品]
|
||||
P2[2. 卫生型隔膜表]
|
||||
P3[3. 隔膜表P]
|
||||

|
||||
P5[5. 膜盒压力表YE]
|
||||
P6[6. 精密压力表YB]
|
||||
P7[7. 电接点压力表YX]
|
||||
P8[8. 常规表Y]
|
||||
P9[9. 其他]

||||

|
||||
|
||||

|
||||
L1 --> P2

P2 -.-> L2[排除后检查]

### 为什么需要优先级？
|
||||
|
||||
某些型号可能同时满足多个分类条件，优先级确保正确的分类：
|
||||
|
||||
| 型号 | 可能的分类 | 正确分类 | 原因 |
|
||||
|------|------------|----------|------|
|
||||
| `PYTH...F6AP...` | 喷涂产品 / 卫生型隔膜表 / 隔膜表 | **喷涂产品** | F6AP含P，优先级1 |
|
||||
| `PYTH...F6A...` | 卫生型隔膜表 / 隔膜表 | **卫生型隔膜表** | F6A检测，优先级2 |
|
||||
| `PYTH...` | 隔膜表 | **隔膜表** | P开头，优先级3 |
|
||||
| `YCSH...` | 差压表 / 常规表 | **差压表** | YC比Y更具体 |

## 总结
|
||||
|
||||
### 算法关键点
|
||||
|
||||
1. **优先级漏斗设计** - 从最特殊到最一般的分类顺序
|
||||
2. **字符串解析** - 基于 `竖线` 和 `-` 分隔符的提取逻辑
|
||||
3. **前缀匹配** - 使用 `Like "P*"` 模式匹配主型号
|
||||
4. **边界处理** - 空值、缺失段等异常情况的处理
|
||||
|
||||
### 扩展性
|
||||
|
||||
- 添加新分类：在决策漏斗中插入新的检测条件
|
||||
- 修改分类规则：调整各检测函数的判断逻辑
|
||||
- 性能优化：使用缓存或批量处理减少重复解析
