创建解码器清单 (AWS CLI)
您可以使用 CreateDecoderManifestAPI 操作来创建解码器清单。下面的示例使用了 AWS CLI。
重要
在创建解码器清单之前，请先创建车辆型号。有关更多信息，请参阅 创建车辆型号。
要创建解码器清单，请运行以下命令。
decoder-manifest-configuration替换为包含配置的 JSON 文件的名称。
aws iotfleetwise create-decoder-manifest --cli-input-json file://decoder-manifest-configuration.json
-
decoder-manifest-name替换为您正在创建的解码器清单的名称。 -
将
vehicle-model-ARN替换为车辆型号的 Amazon 资源名称 (ARN)。 -
（可选）将
description替换为可帮助您识别解码器清单的描述。
有关如何配置分支、属性、传感器和执行器的更多信息，请参阅配置网络接口和解码器信号。
{ "name": "decoder-manifest-name", "modelManifestArn": "vehicle-model-arn", "description": "description", "networkInterfaces": [ { "canInterface": { "name": "myNetworkInterface", "protocolName": "CAN", "protocolVersion": "2.0b" }, "interfaceId": "Qq1acaenByOB3sSM39SYm", "type": "CAN_INTERFACE" } ], "signalDecoders": [ { "canSignal": { "name": "Engine_Idle_Time", "factor": 1, "isBigEndian": true, "isSigned": false, "length": 24, "messageId": 271343712, "offset": 0, "startBit": 16 }, "fullyQualifiedName": "Vehicle.EngineIdleTime", "interfaceId": "Qq1acaenByOB3sSM39SYm", "type": "CAN_SIGNAL" }, { "canSignal": { "name": "Engine_Run_Time", "factor": 1, "isBigEndian": true, "isSigned": false, "length": 24, "messageId": 271343712, "offset": 0, "startBit": 40 }, "fullyQualifiedName": "Vehicle.EngineRunTime", "interfaceId": "Qq1acaenByOB3sSM39SYm", "type": "CAN_SIGNAL" } ] }
-
decoder-manifest-name替换为您正在创建的解码器清单的名称。 -
将
vehicle-model-ARN替换为车辆型号的 Amazon 资源名称 (ARN)。 -
（可选）将
description替换为可帮助您识别解码器清单的描述。
结构（结构体）中属性节点的顺序必须与信号目录和车辆模型（模型清单）中定义的顺序保持一致。有关如何配置分支、属性、传感器和执行器的更多信息，请参阅配置网络接口和解码器信号。
