MES 生产作业计划协同 WinForm 中间件组件（主支轴事件委托 + 多指令调度）
你需要开发一套面向 MES 生产作业计划协同的 WinForm 中间件，核心基于产线工站流程的主支轴事件委托封装设计模式，实现多指令端 / 应用的调度协同，让主产线（主轴）与分支工位（支轴）的作业计划通过事件委托机制完成联动调度，确保生产流程的时序一致性和指令协同性。
以下是完整的工业级解决方案，包含主支轴事件委托核心架构、多指令调度中心、可视化作业计划协同界面，兼顾 MES 系统的实时性、可靠性和可扩展性。
一、核心设计理念与架构
1. 主支轴事件委托设计
MES 产线作业流程中，主轴代表核心产线节拍（如总装线），支轴代表配套工位（如预装工位、检测工位），通过事件委托实现：
- 主轴事件触发支轴联动（如主轴到料 → 支轴开始预装）
- 支轴状态回调主轴（如支轴完成 → 主轴允许流转）
- 异常事件全局广播（如支轴缺料 → 主轴暂停 + 告警）
委托注册 事件触发 状态回调 指令封装 指令分发 主轴控制器 主轴事件中心 支轴控制器1 支轴控制器2 支轴控制器N 支轴1执行作业 支轴2执行作业支轴N执行作业 多指令调度中心 MES数据库 产线执行端 告警中心

2. 核心事件类型（主支轴协同）
| 事件分类 | 主轴事件 | 支轴事件 | 全局事件 |
|---|---|---|---|
| 作业计划事件 | 主轴计划启动 / 暂停 / 完成 / 取消 | 支轴计划绑定 / 启动 / 完成 / 异常 | 计划同步 / 版本更新 / 冲突检测 |
| 物料协同事件 | 主轴物料齐套 / 缺料 / 补料 | 支轴物料需求 / 齐套确认 / 消耗上报 | 物料调拨指令 / 库存告警 |
| 流程控制事件 | 主轴节拍调整 / 工序跳转 / 批次切换 | 支轴工序就绪 / 等待 / 流转 | 产线启停 / 模式切换 / 紧急停机 |
| 异常处理事件 | 主轴设备异常 / 质量异常 | 支轴作业异常 / 人员异常 | 异常上报 / 自动恢复 / 人工干预 |
3. 多指令端调度规则
| 指令端类型 | 接收事件 | 输出指令 | 委托回调机制 |
|---|---|---|---|
| 主轴控制端 | 支轴完成 / 异常 / 物料齐套 | 主轴流转 / 暂停 / 节拍调整 | 注册支轴状态回调委托 |
| 支轴执行端 | 主轴启动 / 节拍调整 / 暂停 | 支轴作业启动 / 调整 / 等待 | 注册主轴指令委托 |
| MES 计划端 | 主支轴状态变更 | 计划更新 / 进度同步 / 报表 | 注册全局状态变更委托 |
| 物料调拨端 | 支轴物料需求 / 主轴缺料 | 调拨指令 / 补料通知 | 注册物料需求委托 |
| 异常告警端 | 主支轴异常事件 | 告警指令 / 派工通知 | 注册异常事件委托 |

MES的生产作业计划协同，产线的工站流程的组合主支轴事件委托封装形式，开发一个多指令端/应用调度模式的Winform中间件功能界面组件
MES 生产作业计划协同 WinForm 中间件组件（主支轴事件委托 + 多指令调度）
你需要开发一套面向 MES 生产作业计划协同的 WinForm 中间件，核心是基于产线工站流程的主支轴事件委托封装模式，实现多指令端 / 应用的调度协同，让主轴（核心产线）与支轴（分支工位）的作业计划通过事件委托机制联动，同时支持多指令端的调度交互，最终落地为可视化的 WinForm 界面组件。
以下是可直接落地的工业级解决方案，包含完整的架构设计、核心代码、界面实现和部署说明，兼顾 MES 系统的实时性、可靠性和可扩展性。
一、核心设计思路
1. 主支轴事件委托核心逻辑
- 主轴：核心产线节拍（如总装线），作为调度核心，触发支轴联动
- 支轴：配套工位（如预装 / 检测工位），响应主轴指令并反馈状态
- 事件委托：封装主轴→支轴、支轴→主轴的事件触发 / 回调逻辑，解耦主支轴依赖
- 多指令调度：支持 MES 计划端、产线执行端、物料调拨端、异常告警端等多端指令协同
2. 整体架构
委托注册 指令分发 状态同步 主轴控制器 事件中心<单例> 支轴控制器1 支轴控制器2 多指令调度中心 MES计划端 产线执行端 物料调拨端 异常告警端 WinForm可视化界面

VALUES ('MA-001', '总装主轴', 'LINE-001', 0, NULL, 60),
('BA-001-01', '预装工位', 'LINE-001', 1, 'MA-001', 50),
('BA-001-02', '检测工位', 'LINE-001', 1, 'MA-001', 70);
INSERT INTO MesCoopJobPlan (JobPlanNo, JobPlanName, LineCode, MainAxisCode, ProductCode, PlanQty, PlanStartTime)
VALUES ('JP-20260101-001', 'A产品总装计划', 'LINE-001', 'MA-001', 'PROD-001', 1000, '2026-01-01 08:00:00');

三、部署与使用说明
1. 环境准备
- .NET Framework 4.8 或更高版本
- SQL Server 2016 或更高版本
- Visual Studio 2019/2022（WinForm 开发环境）
2. 部署步骤
- 执行数据库初始化脚本，创建 MES_Cooperation 数据库及表结构
- 在 Visual Studio 中创建 WinForm 项目，引用 Newtonsoft.Json 和 Dapper NuGet 包
- 将上述代码复制到项目中，调整数据库连接字符串
- 编译并运行项目
3. 核心功能使用
- 轴选择：下拉框选择轴，或直接点击界面上的轴图形
- 计划操作：启动 / 暂停作业计划，自动触发主支轴联动
- 异常上报：上报物料缺料 / 设备异常，自动暂停关联轴并触发告警
- 指令日志：实时查看多指令端的调度指令执行情况
- 事件日志：查看所有事件的触发和处理记录
四、总结
关键点回顾
- 主支轴事件委托封装：通过单例事件中心实现委托的注册 / 触发 / 注销，解耦主支轴依赖，支持异步事件处理
- 多指令调度模式：基于事件自动生成调度指令，分发到 MES 计划端、物料调拨端等多指令端，确保协同一致性
- 可视化 WinForm 组件：集成轴状态可视化、操作按钮、日志展示，支持鼠标交互和状态实时刷新
- 工业级可靠性：包含异常处理、日志记录、数据库事务，符合 MES 系统的稳定性要求
该组件可直接集成到现有 MES 系统中，支持产线工站流程的主支轴协同调度，适配多指令端的交互需求，具备良好的扩展性和维护性。
