李工ROBOT架构之扩展 TestController 以支持更多实验（如 TDDB、TC）并增强可扩展性

基于您的需求，我将为半导体可靠性测试机上位机系统提供以下内容的详细实现：扩展 TestController 以支持更多实验（如 TDDB、TC）并增强可扩展性，以及硬件驱动层协议扩展（支持 Modbus、UDP）。内容基于 .NET Core 8.0、WPF、MVVM 模式、Prism 框架，并使用中文描述，确保代码可落地且易于扩展。我将提供具体代码示例、设计思路和性能优化建议，并实现动态配置切换不同测试模式的功能。

---

一、扩展 TestController 支持更多实验（TDDB、TC）

1.1 功能描述

• 目标：扩展 TestController 支持 TDDB（时间依赖介电击穿）、TC（温度循环）等实验，并确保高可扩展性。

• 动态配置：支持通过配置文件或 UI 切换测试模式（如 HTRB、HTGB、TDDB、TC）。

• 可扩展性：通过抽象接口和反射机制，允许动态添加新实验类型。

• 测试模式切换：支持用户在运行时选择不同测试模式（如动态、静态、高压动态）。

1.2 设计思路

• 接口抽象：扩展 ITest 接口，定义通用实验方法（如初始化、执行步骤、采集数据）。

• 工厂模式：使用工厂类 TestFactory 创建具体实验实例。

• 配置驱动：通过 JSON 或数据库配置实验流程和模式，动态加载。

• 事件驱动：通过事件通知 UI 层实验状态和数据更新。

• 异步执行：使用 async/await 确保非阻塞操作。

1.3 代码实现

ITest.cs（扩展接口）

csharp

namespace ReliabilityTestSystem.Core.Tests
{
    public interface ITest
    {
        string TestName { get; }
        string TestMode { get; } // 新增：测试模式（如动态、静态）
        Task InitializeAsync(TestConfig config);
        Task StartAsync();
        Task PauseAsync();
        Task StopAsync();
        event EventHandler DataUpdated;
        event EventHandler StatusChanged;
    }

    public class TestDataEventArgs : EventArgs
    {
        public string Channel { get; set; }
        public object Data { get; set; }
    }

    public class TestStatusEventArgs : EventArgs
    {
        public string Status { get; set; }
    }
}

TestConfig.cs（支持测试模式）

csharp

namespace ReliabilityTestSystem.Core.Tests
{
    public class TestConfig
    {
        public string TestName { get; set; }
        public string TestMode { get; set; } // 动态、静态、高压动态等
        public string Channel { get; set; }
        public List Steps { get; set; } = new List();
    }

    public class TestStep
    {
        public string StepType { get; set; } // 升温、升压、延时等
        public string Parameter { get; set; }
        public string Description { get; set; }
    }
}

TestFactory.cs（工厂类）

csharp

using System;
using System.Collections.Generic;
using System.Reflection;

namespace ReliabilityTestSystem.Core.Tests
{
    public class TestFactory
    {
        private readonly IDeviceRegistry _deviceRegistry;
        private readonly Dictionary _testTypes = new Dictionary();

        public TestFactory(IDeviceRegistry deviceRegistry)
        {
            _deviceRegistry = deviceRegistry;
            RegisterTests();
        }

        private void RegisterTests()
        {
            // 扫描程序集，注册所有实现 ITest 的类
            var testTypes = Assembly.GetExecutingAssembly()
                .GetTypes()
                .Where(t => typeof(ITest).IsAssignableFrom(t) && !t.IsInterface && !t.IsAbstract);

            foreach (var type in testTypes)
            {
                var instance = (ITest)Activator.CreateInstance(type, _deviceRegistry);
                _testTypes[instance.TestName] = type;
            }
        }

        public ITest CreateTest(string testName, TestConfig config)
        {
            if (_testTypes.TryGetValue(testName, out var type))
            {
                var test = (ITest)Activator.CreateInstance(type, _deviceRegistry);
                test.InitializeAsync(config).GetAwaiter().GetResult();
                return test;
            }
            throw new ArgumentException($"未知实验类型: {testName}");
        }

        public IEnumerable GetAvailableTests() => _testTypes.Keys;
    }
}

TestController.cs（扩展支持动态切换）

using System;
using System.Collections.Generic;
using System.Threading.Tasks;

namespace ReliabilityTestSystem.Core.Tests
{
    public class TestController
    {
        private readonly TestFactory _testFactory;
        private readonly Dictionary _activeTests = new Dictionary();
        private string _currentTestMode = "静态"; // 默认测试模式

        public TestController(TestFactory testFactory)
        {
            _testFactory = testFactory;
        }

        public async Task RegisterTestAsync(string testName, TestConfig config)
        {
            config.TestMode ??= _currentTestMode; // 使用当前模式
            var test = _testFactory.CreateTest(testName, config);
            _activeTests[testName] = test;
        }

        public async Task SwitchTestModeAsync(string testMode)
        {
            _currentTestMode = testMode;
            foreach (var test in _activeTests.Values)
            {
                // 根据模式调整实验参数
                if (test.TestMode != testMode)
                {
                    await test.StopAsync();
                    // 重新初始化实验（示例中简化处理）
                }
            }
        }

        public async Task StartTestAsync(string testName)
        {
            if (_activeTests.TryGetValue(testName, out var test))
            {
                await test.StartAsync();
            }
        }

        public async Task PauseTestAsync(string testName)
        {
            if (_activeTests.TryGetValue(testName, out var test))
            {
                await test.PauseAsync();
            }
        }

        public async Task StopTestAsync(string testName)
        {
            if (_activeTests.TryGetValue(testName, out var test))
            {
                await test.StopAsync();
                _activeTests.Remove(testName);
            }
        }

二、协议扩展（Modbus、UDP）

2.1 功能描述

• Modbus 协议：支持 Modbus RTU（串口）和 Modbus TCP（网络）。

• UDP 协议：支持无连接的数据传输，适合快速广播。

• 动态加载：通过配置文件或 UI 选择协议和驱动。

• 高性能：异步通信，批量处理数据。

2.2 驱动接口扩展

csharp

namespace ReliabilityTestSystem.Core.Drivers
{
    public interface IDeviceDriver
    {
        string Id { get; }
        string Name { get; }
        string Protocol { get; } // 新增：协议类型（COM、TCP、Modbus、UDP）
        Task InitializeAsync();
        Task
