+# V1.2.2 更新日志
+
+- **更新日期**: 2026年06月09日
+- **版本号**: 1.2.2
+
+##  新增功能
+
+### 1. 数据修正系数配置
+- **新增数据修正系数功能**：在系统设置中新增 X/Y 双方向修正系数配置，支持分别设置 `xK`、`xB`、`yK`、`yB`
+- **支持线性修正公式**：页面显示值按 `newValue = K * originalValue + B` 计算
+- **本地持久化保存**：修正系数自动保存到本地，上位机重启后可继续沿用
+- **页面更新提示**：修正系数修改成功后，页面会给出即时提示，方便确认操作结果
+
+### 2. 修正值统一应用
+- **曲线显示统一使用修正值**：X/Y 方向曲线改为显示修正后的数据
+- **实时数据显示统一使用修正值**：右侧实时数据显示与曲线口径保持一致
+- **报警判断统一使用修正值**：报警逻辑基于修正后的 X/Y 数据进行判断
+- **CSV 导出统一使用修正值**：实时数据与报警数据导出均使用修正后的值
+
+##  技术细节
+
+### 修正系数
+- 修正系数项：
+  - `xK`
+  - `xB`
+  - `yK`
+  - `yB`
+- 默认值：
+  - `xK = 1`
+  - `xB = 0`
+  - `yK = 1`
+  - `yB = 0`
+
+### 数据处理策略
+- 页面接收到实时传感器数据后，先计算并冻结：
+  - `correctedX`
+  - `correctedY`
+- 冻结结果用于：
+  - 历史曲线显示
+  - 实时数据显示
+  - 报警判断
+  - 实时 CSV 导出
+  - 报警 CSV 导出
+
+##  影响范围
+- 挠度采集页 X/Y 曲线显示
+- 挠度采集页实时数据显示
+- 系统设置中的数据修正系数配置
+- 报警判断逻辑
+- 实时数据 CSV 导出
+- 报警数据 CSV 导出
+
+##  依赖更新
+- 无依赖包更新
+
+##  注意事项
+1. 修正系数仅作用于当前上位机本地显示与导出，不会下发到设备端。
+2. 设备侧“测点设置”中的“计算系数”仍为独立参数，与本次新增的上位机修正系数互不替代。
+3. 修改修正系数后，仅后续新采集数据使用新系数，已有历史数据保持采集当时的结果。
+4. 如需验证导出结果，建议同时比对页面曲线、实时数据显示与 CSV 记录的一致性。
