库位管理
动态避障

二、核心模块实现

1. Xbox控制器输入处理
csharp 复制代码 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SharpDX.XInput;

public class XboxController
{
    private Controller _controller;
    private const int VIBRATION_DURATION = 200; // 振动持续时间(ms)
    
    public XboxController(PlayerIndex index = PlayerIndex.One)
    {
        _controller = new Controller(index);
        if (!_controller.IsConnected)
            throw new InvalidOperationException("控制器未连接");
    }

    public (float X, float Y) GetLeftThumbstick()
    {
        var state = _controller.GetState();
        return (state.Gamepad.sThumbLX / 32767.5f, 
                state.Gamepad.sThumbLY / 32767.5f);
    }

    public bool GetButtonState(Button button)
    {
        return _controller.GetState().Gamepad.Buttons.HasFlag(button);
    }

    public void SetVibration(float leftMotor, float rightMotor)
    {
        var vibration = new Vibration
        {
            LeftMotorSpeed = (ushort)(leftMotor * ushort.MaxValue),
            RightMotorSpeed = (ushort)(rightMotor * ushort.MaxValue)
        };
        _controller.SetVibration(vibration);
        Task.Delay(VIBRATION_DURATION).ContinueWith(_ => 
            _controller.SetVibration(Vibration.Zero));
    }
}

public enum Button
{
    A = GamepadButtonFlags.A,
    B = GamepadButtonFlags.B,
    X = GamepadButtonFlags.X,
    Y = GamepadButtonFlags.Y,
    LB = GamepadButtonFlags.LB,
    RB = GamepadButtonFlags.RB
}
2. AGV通信协议实现
csharp 复制代码 
using System.Net.Sockets;
using System.Text;

public class AgvCommunication
{
    private TcpClient _client;
    private NetworkStream _stream;
    private readonly byte[] _header = { 0xAA, 0x55 };
    private readonly byte[] _footer = { 0x55, 0xAA };

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

    public void SendCommand(string command)
    {
        var data = Encoding.ASCII.GetBytes(_header.Concat(Encoding.ASCII.GetBytes(command))
                                            .Concat(_footer).ToArray());
        _stream.Write(data, 0, data.Length);
    }

    public string ReceiveResponse()
    {
        byte[] buffer = new byte[1024];
        int bytesRead = _stream.Read(buffer, 0, buffer.Length);
        return Encoding.ASCII.GetString(buffer, 0, bytesRead);
    }
}

// 示例指令集
public static class AgvCommands
{
    public const string MOVE_FORWARD = "MOVE_FWD";
    public const string MOVE_BACKWARD = "MOVE_BWD";
    public const string TURN_LEFT = "TURN_L";
    public const string TURN_RIGHT = "TURN_R";
    public const string STOP = "STOP";
    public const string PICKUP = "PICKUP";
    public const string DROP = "DROP";
}
3. 动态路径规划算法
csharp 复制代码 
using System.Collections.Generic;
using System.Drawing;

public class PathPlanner
{
    private class Node
    {
        public Point Position { get; set; }
        public Node Parent { get; set; }
        public double G { get; set; }  // 起点到当前点代价
        public double H { get; set; }  // 当前点到终点启发值
        public double F => G + H;      // 总代价

        public Node(Point pos, Node parent = null)
        {
            Position = pos;
            Parent = parent;
            G = 0;
            H = 0;
        }
    }

    public List<Point> FindPath(int[,] grid, Point start, Point end)
    {
        var openList = new List<Node>();
        var closedList = new HashSet<Point>();
        
        openList.Add(new Node(start));
        
        while (openList.Count > 0)
        {
            var current = openList.OrderBy(n => n.F).First();
            openList.Remove(current);
            closedList.Add(current.Position);

            if (current.Position == end) 
                return ReconstructPath(current);

            foreach (var neighbor in GetNeighbors(current.Position, grid))
            {
                if (closedList.Contains(neighbor)) continue;

                double tentativeG = current.G + 1; // 假设每格代价为1
                var neighborNode = openList.FirstOrDefault(n => n.Position == neighbor);
                
                if (neighborNode == null || tentativeG < neighborNode.G)
                {
                    neighborNode = new Node(neighbor, current);
                    neighborNode.G = tentativeG;
                    neighborNode.H = CalculateH(neighbor, end);
                    openList.Add(neighborNode);
                }
            }
        }
        return null; // 无路径
    }

    private List<Point> ReconstructPath(Node node)
    {
        var path = new List<Point>();
        while (node != null)
        {
            path.Add(node.Position);
            node = node.Parent;
        }
        path.Reverse();
        return path;
    }

    private IEnumerable<Point> GetNeighbors(Point pos, int[,] grid)
    {
        var directions = new[] { new Point(0,1), (1,0), (0,-1), (-1,0) };
        return directions.Select(d => new Point(pos.X + d.X, pos.Y + d.Y))
                        .Where(p => p.X >=0 && p.Y >=0 && 
                                   p.X < grid.GetLength(0) && 
                                   p.Y < grid.GetLength(1) && 
                                   grid[p.X, p.Y] == 0);
    }

    private double CalculateH(Point a, Point b)
    {
        return Math.Abs(a.X - b.X) + Math.Abs(a.Y - b.Y); // 曼哈顿距离
    }
}

三、多AGV协同控制

1. 任务分配算法
csharp 复制代码 
public class TaskScheduler
{
    private readonly Dictionary<byte, AGVStatus> _agvStatus = new();
    
    public void AssignTask(byte agvId, TaskRequest request)
    {
        if (!_agvStatus.ContainsKey(agvId)) return;
        
        var path = PathPlanner.FindPath(
            WarehouseMap.Instance.Grid,
            _agvStatus[agvId].CurrentPosition,
            request.TargetPosition);
        
        SendPathToAGV(agvId, path);
    }

    private void SendPathToAGV(byte agvId, List<Point> path)
    {
        var command = new StringBuilder("PATH:");
        foreach (var p in path)
            command.Append($"{p.X},{p.Y};");
        command.Append("END");
        
        AgvCommunication.Instance.SendCommand(command.ToString());
    }
}

public class TaskRequest
{
    public Point TargetPosition { get; set; }
    public string CargoType { get; set; }
    public int Priority { get; set; }
}
2. 状态同步机制
csharp 复制代码 
public class AGVStatusMonitor
{
    private readonly ConcurrentDictionary<byte, AGVStatus> _statuses = new();
    
    public void UpdateStatus(byte agvId, AGVStatus status)
    {
        _statuses.AddOrUpdate(agvId, status, (_, old) => status);
        
        // 检测异常状态
        if (status.BatteryLevel < 20)
            AlertSystem.Notify($"AGV{agvId} 电量不足！");
        
        if (status.CollisionDetected)
            HandleCollision(agvId);
    }
}

public class AGVStatus
{
    public Point CurrentPosition { get; set; }
    public double BatteryLevel { get; set; }
    public bool CollisionDetected { get; set; }
    public List<Point> Path { get; set; }
}

四、硬件集成方案

1. 传感器数据融合
csharp 复制代码 
public class SensorFusion
{
    private readonly Lidar _lidar;
    private readonly Ultrasonic _ultrasonic;
    private readonly IMU _imu;

    public SensorData GetEnvironmentData()
    {
        return new SensorData
        {
            Distance = _lidar.GetDistance(),
            ObstacleDetected = _ultrasonic.IsObstaclePresent(),
            Orientation = _imu.GetOrientation()
        };
    }
}

public class SensorData
{
    public float Distance { get; set; }
    public bool ObstacleDetected { get; set; }
    public (float Roll, float Pitch, float Yaw) Orientation { get; set; }
}
2. 运动控制实现
csharp 复制代码 
public class MotionController
{
    private readonly PIDController _pidX = new PIDController(0.2, 0.1, 0.05);
    private readonly PIDController _pidY = new PIDController(0.2, 0.1, 0.05);
    
    public void AdjustMovement(SensorData data, Point target)
    {
        double errorX = target.X - CurrentPosition.X;
        double errorY = target.Y - CurrentPosition.Y;
        
        double speedX = _pidX.Calculate(errorX, 0.1);
        double speedY = _pidY.Calculate(errorY, 0.1);
        
        SendDriveCommand(speedX, speedY);
    }
}

public class PIDController
{
    private readonly double _kp, _ki, _kd;
    private double _integral, _previousError;

    public PIDController(double kp, double ki, double kd)
    {
        _kp = kp;
        _ki = ki;
        _kd = kd;
    }

    public double Calculate(double error, double dt)
    {
        _integral += error * dt;
        double derivative = (error - _previousError) / dt;
        _previousError = error;
        return _kp * error + _ki * _integral + _kd * derivative;
    }
}

五、系统部署方案

1. 硬件配置
设备类型 推荐型号 关键参数
AGV底盘 国自机器人P3-001 载重100kg，最大速度2m/s

WORKDIR /app
COPY bin/Release/net6.0/publish/ .
COPY WarehouseDB /database
COPY AgvControlService /services
CMD ["dotnet", "WarehouseControl.dll"]

六、调试与优化

1. 路径规划调试
csharp 复制代码 
public class PathVisualizer
{
    public void DrawPath(List<Point> path)
    {
        var bitmap = new Bitmap(800, 600);
        using (var g = Graphics.FromImage(bitmap))
        {
            g.Clear(Color.White);
            foreach (var p in path)
                g.FillRectangle(Brushes.Red, p.X * 10, p.Y * 10, 8, 8);
        }
        bitmap.Save("path_debug.png");
    }
}
2. 性能监控仪表盘
csharp 复制代码 
public class PerformanceDashboard
{
    private PerformanceCounter _cpuCounter = new("Processor", "% Processor Time");
    private PerformanceCounter _networkCounter = new("Network Interface", "Bytes Received");

    public void UpdateMetrics()
    {
        var cpuUsage = _cpuCounter.NextValue();
        var networkTraffic = _networkCounter.NextValue();
        
        Console.WriteLine($"CPU: {cpuUsage:F1}% | 网络流量: {networkTraffic / 1024} KB/s");
    }
}

七、安全防护方案

  1. 物理安全

    • 紧急停止按钮（硬件级中断）

    • 激光雷达+超声波双重避障

  2. 数据安全

    csharp 复制代码 
    public class SecureCommunication
{
    private readonly Aes _aes = Aes.Create();

    public byte[] Encrypt(byte[] data)
    {
        using (var encryptor = _aes.CreateEncryptor())
        using (var ms = new MemoryStream())
        {
            cs.Write(data, 0, data.Length);
            return ms.ToArray();
        }
    }
}

{
    private readonly Dictionary<byte, AGVStatus> _fleetStatus = new();
    
    public void AvoidCollision(byte agvId)
    {
        var status = _fleetStatus[agvId];
        var nearby = _fleetStatus.Values
            .Where(a => a.Id != agvId && Distance(status.Position, a.Position) < 1.5)
            .ToList();
        
        foreach (var other in nearby)
        {
            SendEmergencyStop(other.Id);
            CalculateAlternativePath(agvId);
        }
    }
}
2. 仓库数字孪生
csharp 复制代码 
public class DigitalTwin
{
    private readonly WarehouseMap _map = new();
    
    public void UpdateTwinState(IEnumerable<AGVStatus> statuses)
    {
        lock (_map)
        {
            foreach (var status in statuses)
                _map.UpdatePosition(status.Id, status.CurrentPosition);
        }
    }
}
