AWS IoT FleetWise Beispiele mit SDK for Java 2.x

Die folgenden Codebeispiele zeigen Ihnen, wie Sie mithilfe von AWS SDK for Java 2.x with Aktionen ausführen und allgemeine Szenarien implementieren AWS IoT FleetWise.

Bei Grundlagen handelt es sich um Code-Beispiele, die Ihnen zeigen, wie Sie die wesentlichen Vorgänge innerhalb eines Services ausführen.

Aktionen sind Codeauszüge aus größeren Programmen und müssen im Kontext ausgeführt werden. Während Aktionen Ihnen zeigen, wie Sie einzelne Service-Funktionen aufrufen, können Sie Aktionen im Kontext der zugehörigen Szenarios anzeigen.

Jedes Beispiel enthält einen Link zum vollständigen Quellcode, in dem Sie Anweisungen zum Einrichten und Ausführen des Codes im Kontext finden.

Erste Schritte

Die folgenden Codebeispiele veranschaulichen, wie Sie mit der Verwendung von AWS IoT FleetWise beginnen.

                System.err.println("Error listing signal catalogs: " + e.awsErrorDetails().errorMessage());
                throw new RuntimeException(e);
            }
        }
    }

Grundlagen

Wie das aussehen kann, sehen Sie am nachfolgenden Beispielcode:

  • Erstellen Sie eine Sammlung standardisierter Signale.

  • Erstellen Sie eine Flotte, die eine Gruppe von Fahrzeugen darstellt.

  • Erstellen Sie ein Modellmanifest.

  • Erstellen Sie ein Decoder-Manifest.

  • Überprüfen Sie den Status des Modellmanifests.

  • Überprüfen Sie den Status des Decoders.

  • Erstellen Sie ein IoT-Ding.

  • Erstellen Sie ein Fahrzeug.

  • Fahrzeugdetails anzeigen.

  • Löschen Sie die AWS IoT FleetWise Vermögenswerte.

                 AWS IoT FleetWise is a managed service that simplifies the 
                 process of collecting, organizing, and transmitting vehicle 
                 data to the cloud in near real-time. Designed for automakers 
                 and fleet operators, it allows you to define vehicle models, 
                 specify the exact data you want to collect (such as engine 
                 temperature, speed, or battery status), and send this data to 
                 AWS for analysis. By using intelligent data collection 
                 techniques, IoT FleetWise reduces the volume of data 
                 transmitted by filtering and transforming it at the edge, 
                 helping to minimize bandwidth usage and costs. 
                
                At its core, AWS IoT FleetWise helps organizations build 
                scalable systems for vehicle data management and analytics, 
                supporting a wide variety of vehicles and sensor configurations. 
                You can define signal catalogs and decoder manifests that describe 
                how raw CAN bus signals are translated into readable data, making 
                the platform highly flexible and extensible. This allows 
                manufacturers to optimize vehicle performance, improve safety, 
                and reduce maintenance costs by gaining real-time visibility 
                into fleet operations.
