更新停靠站狀態

本文件假設您熟悉下列項目：

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。

接著，您可以傳送更新至 Fleet Engine，藉此管理任務在整個生命週期中的進度，讓 Fleet Engine 在任務流程中盡可能執行路徑和狀態更新。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。這樣一來，車隊營運人員和使用者就能針對任務進度進行回報和分析。這些狀態更新如下：

  • 行程中：VehicleStop 的 STATE 列舉使用 ENROUTE 表示停靠站是車輛行程清單中的下一個停靠站。從工作角度來看，這表示與停靠點相關的任何工作，都是清單上下一個要完成的工作。
  • Arrived：VehicleStop 的 STATE 列舉使用 ARRIVED 表示車輛已抵達停靠站。從工作角度來看，這表示與停靠站相關的任何工作都會處於運作狀態。
  • 已完成：您可以將站點從車輛的站點清單中移除，藉此標示該站點已完成。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方法更新停止狀態。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，以免發生競爭狀況，並維持單一可靠來源。

車輛正在前往停靠站的途中

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

停止更新的必填欄位

Fleet Engine 會忽略通知中的所有其他欄位。

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

前往停靠站的路線示例

以下範例說明如何使用 Java gRPC 程式庫或對 UpdateDeliveryVehicle 的 HTTP REST 呼叫，通知 Fleet Engine 車輛正在前往下一站的途中。所有其他站都會標示為新站。
