自动化立体仓库系统架构

构建高效的自动化仓储系统：

WMS仓储管理系统设计

实现智能仓储管理：

// WMS仓储管理系统
class WarehouseManagementSystem {
  constructor() {
    this.inventory = new InventoryRepository();
    this.locationManager = new LocationManager();
    this.taskScheduler = new TaskScheduler();
    this.wcsClient = new WCSClient();
  }

  // 创建入库任务
  async createInboundTask(inboundOrder) {
    const items = inboundOrder.items;

    // 1. 预分配库位
    const allocations = await this.allocateLocations(items);

    // 2. 生成入库任务
    const tasks = allocations.map(item => ({
      type: 'INBOUND',
      itemId: item.skuId,
      quantity: item.quantity,
      fromLocation: 'Dock_A',
      toLocation: item.allocatedLocation,
      priority: inboundOrder.priority
    }));

    // 3. 下发任务到WCS
    for (const task of tasks) {
      await this.wcsClient.submitTask(task);
    }

    return { orderId: inboundOrder.orderId, tasks: tasks };
  }

  // 智能库位分配
  async allocateLocations(items) {
    const allocations = [];

    for (const item of items) {
      // 查询可用库位
      const availableLocations = await this.locationManager.getAvailable({
        zone: this.determineZone(item),
        height: item.dimensions.height,
        weight: item.dimensions.weight,
        maxWeight: 1000
      });

      // 使用优化算法选择最佳库位
      const selectedLocation = await this.optimizeLocationSelection(
        item,
        availableLocations
      );

      allocations.push({
        skuId: item.skuId,
        quantity: item.quantity,
        allocatedLocation: selectedLocation
      });
    }

    return allocations;
  }

  // 确定存储区域
  determineZone(item) {
    // 根据商品特性分配存储区域
    if (item.isHazardous) return 'HAZARDOUS';
    if (item.requiresRefrigeration) return 'COLD_CHAIN';
    if (item.turnoverRate > 10) return 'FAST_PICK';
    if (item.quantity > 1000) return 'BULK';
    return 'STANDARD';
  }

  // 库位优化选择
  async optimizeLocationSelection(item, availableLocations) {
    if (availableLocations.length === 0) {
      throw new Error('No available locations');
    }

    // 考虑多个因素评分
    const scored = availableLocations.map(location => {
      let score = 0;

      // 距离因素：优先选择靠近出入口的库位
      score += (100 - location.distanceFromDock) * 0.3;

      // 高度因素：重货放底层，轻货放高层
      if (item.weight > 50 && location.level === 1) {
        score += 30;
      } else if (item.weight < 10 && location.level > 5) {
        score += 30;
      }

      // 品类一致性：同品类尽量集中
      const sameCategoryNearby = await this.locationManager.countSameCategory(
        location, item.category
      );
      score += sameCategoryNearby * 5;

      // 通道优化：平衡各通道任务量
      const channelLoad = await this.taskScheduler.getChannelLoad(location.channel);
      score += (10 - channelLoad) * 2;

      return { location, score };
    });

    // 排序并返回最优库位
    scored.sort((a, b) => b.score - a.score);
    return scored[0].location;
  }

  // 出库任务处理
  async createOutboundTask(outboundOrder) {
    const items = outboundOrder.items;

    // 1. 查找库存
    const inventoryLocations = await this.inventory.findLocations(items);

    // 2. 计算最优拣货路径
    const pickSequence = this.calculatePickSequence(inventoryLocations);

    // 3. 生成拣货任务
    const tasks = pickSequence.map(item => ({
      type: 'OUTBOUND',
      itemId: item.skuId,
      quantity: item.quantity,
      fromLocation: item.location,
      toLocation: 'Dock_B',
      sequence: item.sequence
    }));

    // 4. 下发任务
    for (const task of tasks) {
      await this.wcsClient.submitTask(task);
    }

    return { orderId: outboundOrder.orderId, tasks: tasks };
  }

  // 拣货路径优化
  calculatePickSequence(locations) {
    const sorted = locations.map((loc, index) => ({
      ...loc,
      sequence: index
    }));

    // 使用最近邻算法优化路径
    let currentPosition = { x: 0, y: 0 };
    const optimized = [];

    while (sorted.length > 0) {
      let nearestIndex = 0;
      let nearestDistance = Infinity;

      for (let i = 0; i < sorted.length; i++) {
        const distance = this.calculateDistance(
          currentPosition,
          sorted[i].location
        );

        if (distance < nearestDistance) {
          nearestDistance = distance;
          nearestIndex = i;
        }
      }

      const nearest = sorted.splice(nearestIndex, 1)[0];
      optimized.push(nearest);
      currentPosition = nearest.location;
    }

    return optimized;
  }

  calculateDistance(pos1, pos2) {
    return Math.abs(pos1.x - pos2.x) + Math.abs(pos1.y - pos2.y);
  }
}

设备控制系统集成

与自动化设备的无缝集成：

// WCS设备控制系统
class WarehouseControlSystem {
  constructor() {
    this.stackers = new Map();
    this.conveyors = new Map();
    this.taskQueue = new PriorityQueue({ comparator: (a, b) => a.priority - b.priority });
  }

  // 初始化设备连接
  async initialize() {
    // 连接堆垛机
    const stackerConfigs = await this.loadDeviceConfig('stacker');
    for (const config of stackerConfigs) {
      const stacker = new StackerController(config);
      await stacker.connect();
      this.stackers.set(config.id, stacker);
    }

    // 连接输送线
    const conveyorConfigs = await this.loadDeviceConfig('conveyor');
    for (const config of conveyorConfigs) {
      const conveyor = new ConveyorController(config);
      await conveyor.connect();
      this.conveyors.set(config.id, conveyor);
    }

    // 启动任务处理循环
    this.startTaskProcessing();
  }

  // 任务调度
  async submitTask(task) {
    await this.taskQueue.enqueue(task);

    // 更新任务状态
    this.updateTaskStatus(task.taskId, 'PENDING');
  }

  // 任务处理主循环
  async startTaskProcessing() {
    while (true) {
      if (!this.taskQueue.isEmpty()) {
        const task = await this.taskQueue.dequeue();
        await this.executeTask(task);
      }

      await this.sleep(100);
    }
  }

  // 执行具体任务
  async executeTask(task) {
    this.updateTaskStatus(task.taskId, 'EXECUTING');

    try {
      switch (task.type) {
        case 'INBOUND':
          await this.executeInboundTask(task);
          break;
        case 'OUTBOUND':
          await this.executeOutboundTask(task);
          break;
        case 'TRANSFER':
          await this.executeTransferTask(task);
          break;
        case 'INVENTORY':
          await this.executeInventoryTask(task);
          break;
      }

      this.updateTaskStatus(task.taskId, 'COMPLETED');
    } catch (error) {
      this.updateTaskStatus(task.taskId, 'FAILED', error.message);
    }
  }

  // 执行入库任务
  async executeInboundTask(task) {
    // 1. 分配堆垛机
    const stacker = this.selectOptimalStacker(task.toLocation);

    // 2. 将货物送到指定口
    await this.conveyors.get('main').sendToPort({
      port: stacker.inputPort,
      itemId: task.itemId,
      quantity: task.quantity
    });

    // 3. 堆垛机执行入库
    await stacker.store({
      location: task.toLocation,
      itemId: task.itemId,
      quantity: task.quantity
    });

    // 4. 回报完成
    await this.reportTaskComplete(task.taskId);
  }

  // 选择最优堆垛机
  selectOptimalStacker(targetLocation) {
    let optimalStacker = null;
    let minDistance = Infinity;

    for (const [, stacker] of this.stackers) {
      const distance = this.calculateStackerDistance(stacker, targetLocation);
      if (distance < minDistance) {
        minDistance = distance;
        optimalStacker = stacker;
      }
    }

    return optimalStacker;
  }

  calculateStackerDistance(stacker, location) {
    return Math.abs(stacker.position.x - location.x) +
           Math.abs(stacker.position.y - location.y);
  }

  // 设备状态监控
  async monitorEquipment() {
    const statuses = {};

    // 堆垛机状态
    for (const [id, stacker] of this.stackers) {
      statuses[id] = {
        status: await stacker.getStatus(),
        position: await stacker.getPosition(),
        currentTask: await stacker.getCurrentTask()
      };
    }

    // 输送线状态
    for (const [id, conveyor] of this.conveyors) {
      statuses[id] = {
        status: await conveyor.getStatus(),
        speed: await conveyor.getSpeed(),
        queues: await conveyor.getQueueLength()
      };
    }

    return statuses;
  }
}

库存盘点与校准

自动化盘点系统：

// 智能盘点系统
class InventoryCheckSystem {
  constructor(wms) {
    this.wms = wms;
  }

  // 启动循环盘点
  async startCycleCount(zone) {
    const locations = await this.wms.locationManager.getLocationsByZone(zone);

    // 分批执行盘点
    const batchSize = 20;
    for (let i = 0; i < locations.length; i += batchSize) {
      const batch = locations.slice(i, i + batchSize);
      await this.countBatch(batch);
    }
  }

  // 执行盘点任务
  async countBatch(locations) {
    for (const location of locations) {
      // 读取实际库存
      const actualInventory = await this.wcsClient.getLocationInventory(
        location.code
      );

      // 查询系统库存
      const systemInventory = await this.wms.inventory.getByLocation(
        location.code
      );

      // 比对差异
      const diff = this.compareInventory(systemInventory, actualInventory);

      if (Math.abs(diff) > 0) {
        // 记录差异
        await this.recordDiscrepancy({
          location: location.code,
          skuId: location.skuId,
          systemQty: systemInventory,
          actualQty: actualInventory,
          difference: diff,
          checkTime: Date.now()
        });

        // 调整库存
        if (Math.abs(diff) > 0.01) {  // 允许0.01的误差
          await this.wms.inventory.adjust(location.code, diff);
        }
      }
    }
  }
}
