更新停靠站狀態

本文件假設您熟悉下列項目：

建立運送工作
介紹已排定的工作，其中會說明關係任務、停靠站和交通工具之間詳細介紹

如車隊引擎 Essentials 中的「排定工作」所述，您可以建立工作並將其與車輛停靠站建立關聯，以模擬工作與車輛預期停靠位置之間的實際關聯，讓駕駛員能夠完成工作。

您可以在這裡管理任務在生命週期的進度並向 Fleet Engine 傳送更新，讓 Fleet Engine 以最佳方式執行轉送和狀態並在工作歷程中持續更新其中一個重要方法，就是在車輛接近、抵達和離開停靠站時更新車輛停靠站。如此一來，您就能透過報告和分析機群運算子和使用者。這些狀態更新如下：

En route：VehicleStop 的 STATE 列舉使用 ENROUTE 可表示停靠站位於車輛行程清單的下一站。從工作的角度而言，這代表所有與停靠站相關的工作下一個問題仍未解決
已抵達：VehicleStop 的 STATE 列舉使用 ARRIVED 表示車輛已抵達停靠站。從工作的角度來看表示與停止作業相關聯的任何任務
已完成：您可以將停靠站從車輛的停靠站清單中移除，以標示停靠站已完成。這樣一來，Fleet Engine 就會自動將所有相關聯的工作標示為「已關閉」。如要進一步瞭解如何關閉工作，請參閱「完成工作」。

本文件說明如何使用伺服器端做法更新停止狀態。如果您讓駕駛員能夠使用可信任的裝置管理工作，也可以透過駕駛員應用程式執行這項操作。請只使用一種方法，以免發生競速並維護單一資料來源。

車輛正在前往停靠站

車輛開始前往下一個停靠站時，系統應通知 Fleet Engine。這有助於改善預計到達時間和路線計算結果。

停止更新功能的必填欄位

Fleet Engine 會忽略通知實體中其他所有欄位。

欄位	值
`remainingVehicleJourneySegments`	剩餘車輛停靠站清單，狀態標示為 State.NEW。

導向停靠站範例

以下範例說明如何通知 Fleet Engine 車輛使用 Java gRPC 程式庫或 HTTP 對 UpdateDeliveryVehicle 發出的 REST 呼叫。所有其他停靠站都會標示為新的。

gRPC

 static final String PROJECT_ID = "my-delivery-co-gcp-project";
 static final String VEHICLE_ID = "vehicle-8241890";

 DeliveryServiceBlockingStub deliveryService =
   DeliveryServiceGrpc.newBlockingStub(channel);

 // Vehicle settings
 DeliveryVehicle deliveryVehicle = DeliveryVehicle.newBuilder()
     // Next stop marked as ENROUTE
     .addRemainingVehicleJourneySegments(VehicleJourneySegment.newBuilder()  // 1st stop
        .setStop(VehicleStop.newBuilder()
            .setPlannedLocation(LocationInfo.newBuilder()
                .setPoint(LatLng.newBuilder()

                    .setLongitude(122.4194)))
            .addTasks(TaskInfo.newBuilder().setTaskId(TASK1_ID))
            .setState(VehicleStop.State.ENROUTE)))
     // All other stops marked as NEW
     .addRemainingVehicleJourneySegments(VehicleJourneySegment.newBuilder()  // 2nd stop
        .setStop(VehicleStop.newBuilder()
            .setPlannedLocation(LocationInfo.newBuilder()
                .setPoint(LatLng.newBuilder()
                    .setLatitude(37.3382)
                    .setLongitude(121.8863)))
            .addTasks(TaskInfo.newBuilder().setTaskId(TASK2_ID))
            .setState(VehicleStop.State.NEW)))
     .build();

 // DeliveryVehicle request
 UpdateDeliveryVehicleRequest updateDeliveryVehicleRequest =
   UpdateDeliveryVehicleRequest.newBuilder()  // No need for the header
       .setName(vehicleName)
       .setDeliveryVehicle(deliveryVehicle)
       .setUpdateMask(FieldMask.newBuilder().addPaths("remaining_vehicle_journey_segments"))
       .build();

 try {
   DeliveryVehicle updatedDeliveryVehicle =
       deliveryService.updateDeliveryVehicle(updateDeliveryVehicleRequest);
 } catch (StatusRuntimeException e) {
   Status s = e.getStatus();
   switch (s.getCode()) {
      case NOT_FOUND:
        break;
      case PERMISSION_DENIED:
        break;
   }
   return;
 }

車輛完成一個停靠站

車輛完成停靠後，Fleet Engine 必須收到通知。這會導致所有與停靠站相關的工作都會設為「已關閉」狀態。

停止更新作業的必填欄位

Fleet Engine 會忽略通知實體中其他所有欄位。

欄位	值
`remainingVehicleJourneySegments`	剩餘車輛停靠站清單，狀態標示為 State.NEW。清單上第一個停靠站的狀態必須標示為 State.ENROUTE。
