二、核心功能模块实现

1. 多协议通信模块（CommunicationManager.cs）

public class CommunicationManager : IDisposable
{
    private Dictionary<string, IDevice> _devices = new();
    
    // 初始化设备连接
    public void Initialize()
    {
        _devices.Add("PLC1", new ModbusTcpClient("192.168.1.100", 502));
        _devices.Add("RFID1", new RfidUhfReader("COM3", 9600));
        _devices.Add("AGV1", new CanDevice("can0", 500000));
    }

    // 统一数据接收接口
    public async Task<byte[]> ReadDataAsync(string deviceId)
    {
        return await _devices[deviceId].ReadAsync();
    }

    // 协议转换中心
    public object ParseData(string deviceId, byte[] data)
    {
        return _devices[deviceId] switch
        {
            ModbusTcpClient plc => ParseModbusData(data),
            RfidUhfReader rfid => ParseRfidData(data),
            CanDevice can => ParseCanFrame(data),
            _ => throw new NotSupportedException()
        };
    }
}

2. RFID库存管理（InventoryService.cs）

public class InventoryService
{
    private readonly DatabaseService _db;
    private readonly RfidReader _reader;

    public InventoryService()
    {
        _db = new DatabaseService();
        _reader = new RfidReader("COM3");
    }

    public async Task AutoStockCheckAsync()
    {
        while (true)
        {
            var tags = await _reader.ReadTags();
            foreach (var tag in tags)
            {
                var location = await GetLocationByEpc(tag.Epc);
                _db.UpdateInventory(tag.Epc, location, DateTime.Now);
            }
            await Task.Delay(5000); // 每5秒扫描一次
        }
    }

    private async Task<Location> GetLocationByEpc(string epc)
    {
        // 通过PLC查询货架位置
        var plcResponse = await _plc.SendCommand($"READ_LOC {epc}");
        return JsonConvert.DeserializeObject<Location>(plcResponse);
    }
}

3. AGV路径规划（PathPlanner.cs）

public class PathPlanner
{
    private readonly Graph _mapGraph;
    
    public PathPlanner()
    {
        // 从数据库加载仓库地图
        var nodes = _db.LoadMapNodes();
        _mapGraph = new Graph(nodes);
    }

    public List<Node> FindOptimalPath(string start, string end)
    {
        var algorithm = new AStar();
        return algorithm.Execute(_mapGraph, start, end);
    }
}

// A*算法实现
public class AStar : IPathfindingAlgorithm
{
    public List<Node> Execute(Graph graph, string start, string end)
    {
        // 实现A*寻路逻辑
        // ...
    }
}

---

三、设备控制模块

1. PLC通信（ModbusTcpClient.cs）

public class ModbusTcpClient : IDisposable
{
    private TcpClient _client;
    private NetworkStream _stream;

    public ModbusTcpClient(string ip, int port)
    {
        _client = new TcpClient(ip, port);
        _stream = _client.GetStream();
    }

    public async Task<string> SendCommand(string command)
    {
        var buffer = Encoding.ASCII.GetBytes($"{command}\r\n");
        await _stream.WriteAsync(buffer, 0, buffer.Length);
        
        var response = new byte[1024];
        int bytesRead = await _stream.ReadAsync(response, 0, response.Length);
        return Encoding.ASCII.GetString(response, 0, bytesRead);
    }
}

2. 环境监控（EnvironmentalSensor.cs）

public class EnvironmentalSensor
{
    private readonly SerialPort _port;
    
    public event Action<EnvironmentData> DataReceived;
    
    public EnvironmentalSensor(string portName)
    {
        _port = new SerialPort(portName, 9600);
        _port.DataReceived += OnDataReceived;
        _port.Open();
    }

    private void OnDataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        var data = new byte[_port.BytesToRead];
        _port.Read(data, 0, data.Length);
        var envData = ParseData(data);
        DataReceived?.Invoke(envData);
    }
}

public class EnvironmentData
{
    public float Temperature { get; set; }
    public float Humidity { get; set; }
    public float CO2Level { get; set; }
}

---

四、用户界面设计（WPF）

1. 主界面布局（MainView.xaml）

<Window x:Class="SmartWarehouse.MainView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        Title="智能仓储管理系统" Height="600" Width="1200">
    <DockPanel>
        <!-- 顶部导航 -->
        <Menu DockPanel.Dock="Top">
            <MenuItem Header="库存管理" Click="OnInventoryClick"/>
            <MenuItem Header="设备监控" Click="OnDeviceClick"/>
            <MenuItem Header="路径规划" Click="OnPathClick"/>
        </Menu>

        <!-- 主内容区 -->
        <TabControl>
            <TabItem Header="实时监控">
                <Grid>
                    <DataGrid x:Name="dgRealTimeData" AutoGenerateColumns="False">
                        <DataGrid.Columns>
                            <DataGridTextColumn Header="设备" Binding="{Binding DeviceName}"/>
                            <DataGridTextColumn Header="状态" Binding="{Binding Status}"/>
                            <DataGridTextColumn Header="位置" Binding="{Binding Location}"/>
                        </DataGrid.Columns>
                    </DataGrid>
                </Grid>
            </TabItem>
            
            <TabItem Header="库存看板">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="*"/>
                    </Grid>
                    
                    <TextBlock Text="库存热力图" FontSize="16"/>
                    <Image Grid.Row="1" Source="{Binding HeatMapImage}"/>
                </Grid>
            </TabItem>
        </TabControl>
    </DockPanel>
</Window>

五、数据持久化方案

1. 数据库设计（SQL Server）

-- 设备信息表
CREATE TABLE Devices (
    DeviceID INT PRIMARY KEY IDENTITY(1,1),
    DeviceName NVARCHAR(50) NOT NULL,
    IPAddress VARCHAR(15),
    Port INT,
    LastConnected DATETIME DEFAULT GETDATE()
);

-- 库存记录表
CREATE TABLE Inventory (
    ItemID INT PRIMARY KEY IDENTITY(1,1),
    EPC NVARCHAR(50) UNIQUE,
    Location NVARCHAR(20),
    Quantity INT CHECK(Quantity >= 0),
    LastUpdate DATETIME DEFAULT GETDATE()
);

-- 环境监测表
CREATE TABLE EnvironmentData (
    RecordID INT PRIMARY KEY IDENTITY(1,1),
    SensorID INT,
    Temperature FLOAT,
    Humidity FLOAT,
    CO2Level FLOAT,
    Timestamp DATETIME DEFAULT GETDATE()
);

---

六、关键算法实现

1. 库存预警算法

public class InventoryAlert
{
    private readonly DatabaseService _db;
    
    public event EventHandler<AlertEvent> AlertTriggered;
    
    public InventoryAlert()
    {
        _db = new DatabaseService();
        CheckInventoryLevels();
    }

    private void CheckInventoryLevels()
    {
        var lowStockItems = _db.GetItemsWhere(q => q.Quantity < 10);
        foreach (var item in lowStockItems)
        {
            AlertTriggered?.Invoke(this, new AlertEvent {
                Severity = AlertLevel.High,
                Message = $"物料 {item.EPC} 库存低于阈值！"
            });
        }
    }
}

2. 设备状态监控

public class DeviceMonitor
{
    private readonly Dictionary<string, DeviceStatus> _statuses = new();
    
    public DeviceMonitor()
    {
        InitializeDevices();
        StartPolling();
    }

    private void InitializeDevices()
    {
        _statuses.Add("PLC1", new DeviceStatus { DeviceName = "主控PLC", Status = "在线" });
        _statuses.Add("AGV1", new DeviceStatus { DeviceName = "搬运AGV", Status = "待机" });
    }

    private void StartPolling()
    {
        var timer = new Timer(5000);
        timer.Elapsed += async (s, e) => 
        {
            foreach (var device in _statuses.Keys)
            {
                var status = await GetDeviceStatus(device);
                _statuses[device].Update(status);
            }
        };
        timer.Start();
    }
}

七、系统集成方案

1. REST API服务

[ApiController]
[Route("api/[controller]")]
public class WarehouseController : ControllerBase
{
    private readonly WarehouseService _service;

    [HttpGet("inventory")]
    public async Task<IActionResult> GetInventory()
    {
        var data = await _service.GetInventoryReport();
        return Ok(data);
    }

    [HttpPost("order")]
    public IActionResult CreateOrder([FromBody] OrderRequest request)
    {
        var result = _service.ProcessOrder(request);
        return result ? Ok() : BadRequest("订单处理失败");
    }
}

2. MQTT消息订阅

public class MqttClientManager
{
    private MqttClient _client;

    public async Task ConnectAsync()
    {
        _client = new MqttClient("broker.hivemq.com");
        await _client.ConnectAsync("warehouse-client");
        
        _client.SubscribeAsync("warehouse/+/status", 1);
        _client.ApplicationMessageReceivedHandler = new MqttApplicationMessageReceivedHandlerDelegate(e => 
        {
            HandleMqttMessage(e.ApplicationMessage);
        });
    }
}

八、部署与运维

1. Docker部署配置

FROM mcr.microsoft.com/dotnet/runtime:6.0
WORKDIR /app
COPY ./bin/Release/net6.0/publish/ .
EXPOSE 80
ENTRYPOINT ["dotnet", "SmartWarehouse.dll"]

2. 监控仪表盘

public class DashboardService
{
    private readonly PerformanceCounter _cpuCounter = new("Processor", "% Processor Time", "_Total");
    private readonly PerformanceCounter _ramCounter = new("Memory", "Available MBytes");
    
    public DashboardData GetSystemStatus()
    {
        return new DashboardData {
            CpuUsage = _cpuCounter.NextValue(),
            MemoryAvailable = _ramCounter.NextValue(),
            NetworkTraffic = GetNetworkUsage()
        };
    }
}
