IoTDB-Collector 用户手册

依赖

• JDK >= 11

部署

1. 下载 IoTDB-Collector 的 zip 包,并解压 zip 包得到 IoTDB-Collector 文件夹
2. 修改 IoTDB-Collector/conf 文件夹下的 db.properties 文件中的 IoTDB 的配置信息

dbIp = 127.0.0.1
dbPort = 6667
dbUser = root
dbPasswd = root

3. 在 IoTDB-Collector 文件夹下使用 ./bin/start.sh 即可启动 IoTDB-Collector

使用示例

连接 OPC UA 服务并采集数据

1. 修改 IoTDB-Collector/conf/opcua 下的 opcua-points.json 文件，配置要采集的点位地址

{
  "protocol": "opcua",
  "point_refs": [
    {
      "name":"DEC21TT104_PV",
      "address":"ns=1;s=t|TT21104/PV.PV_Out#Value",
      "data_type":"float"
    },
    {
      "name":"DEC21TT104_PV_UN",
      "address":"ns=1;s=t|TT21104/PV.PV_Unit",
      "data_type":"int"
    },
    {
      "name": "DEC21HV415_Mon",
      "address": "ns=1;s=t|HV21415/V.Monitor",
      "data_type": "boolean"
    }
  ]
}

2. 修改 IoTDB-Collector/conf/opcua 下的 opcua-tasks.json 文件，配置点位对应IoTDB入库的名称及采集频率

{
  "protocol":"opcua",
  "tasks":[
    {
      "group_id":"opcua1",
      "interval_us":1000000,
      "points":[
        {
          "name_ref":"DEC21TT104_PV",
          "db_name":"DEC21TT104_PV",
          "db_data_type":"FLOAT"
        },
        {
          "name_ref":"DEC21TT104_PV_UN",
          "db_name":"DEC21TT104_PV_UN",
          "db_data_type":"INT32"
        },
        {
          "name_ref":"DEC21HV415_Mon",
          "db_name":"DEC21HV415_Mon",
          "db_data_type":"BOOLEAN"
        }
      ]
    }
  ]
}

3. 调用接口，启动采集程序( endpointUrl 配置 OPC UA 连接地址)

curl --request PUT 'http://127.0.0.1:8081/start/opcua' \
--header 'Authorization: Basic dG9tOjMyMTEz' \
--header 'Content-Type: application/json' \
--data '{
	"deviceId": "opcua",
	"deviceOwner": "opcua",
	"protocolName": "opcua",
	"deviceProperties": {
		"endpointUrl": "opc.tcp://192.168.0.1:4862",
		"authWay": "0",
		"username": "",
		"password": ""
	}
}'

4.查看 IoTDB 是否有数据写入

5. 停止 OPC UA 数据采集

curl --request DELETE 'http://127.0.0.1:8081/stop/opcua' \
--header 'Authorization: Basic dG9tOjMyMTEz' \
