前言
本文主要介绍thingsboard-gateway使用modbus协议接入设备信息,使用thingsboard-gateway版本为2.5.5.2。
github仓库地址:https://github.com/thingsboard
文章建立在thingsboard以及tingsboard-gateway服务搭建好的基础上, 搭建thingsboard-gateway服务可以参考官方文档:http://www.ithingsboard.com/docs/iot-gateway/installation/
1.modbus poll下载及配置
2.修改tb_gateway.yaml
tb_gateway.yaml示例。
connectors:
- configuration: modbus.json
name: Modbus
type: modbus
storage:
max_records_count: 100000
read_records_count: 100
type: memory
thingsboard:
host: 192.168.80.251 #thingsboard服务ip
port: 1883 #thingsboard服务mqtt端口
remoteConfiguration: false
security:
accessToken: 4vR9kMQrKom2xD9FgnkQ #设备的访问令牌
3.修改modbus.json
{
"master": {
"slaves": [
{
"attributes": [],
"byteOrder": "BIG",
"wordOrder": "BIG",
"connectAttemptCount": 5,
"connectAttemptTimeMs": 5000,
"waitAfterFailedAttemptsMs": 300000,
"deviceName": "test-modbus1", #设备名称,可自定义
"host": "192.168.80.251", #modbus服务器ip
"type": "tcp",
"method": "socket",
"pollPeriod": 30000, #数据获取间隔,单位ms
"port": 5021, #modbus服务器端口
"retries": true,
"unitId": 10, #对应modbus poll中的Slave ID
"sendDataOnlyOnChange": false, #只有数据发生改变才发送,此处填false
"timeout": 35,
"timeseries": [
{
"address": 1, #对应modbus poll中的address
"functionCode": 3, #对应modbus poll中的function 03选项
"objectsCount": 2, #数据长度,2表示接收2个返回的字节
"tag": "modbus", #字段名,可自定义
"type": "bytes"
}
]
},
{
"attributes": [],
"byteOrder": "BIG",
"wordOrder": "BIG",
"connectAttemptCount": 5,
"connectAttemptTimeMs": 5000,
"waitAfterFailedAttemptsMs": 300000,
"deviceName": "test-modbus2",
"host": "192.168.80.251",
"type": "tcp",
"method": "socket",
"pollPeriod": 30000,
"port": 5021,
"retries": true,
"unitId": 17,
"sendDataOnlyOnChange": false,
"timeout": 35,
"timeseries": [
{
"address": 11,
"functionCode": 3,
"objectsCount": 2,
"tag": "modbus",
"type": "bytes"
}
]
}
]
}
}
4.重启thingsboard-gateway服务
重启:docker restart thingsboard-gateway

重启完成后thingsboard服务中会出现上面modbus.json中配置的设备,如果没有设备,说明环境有问题,查看日志:docker logs -t thingsboard-gateway
