modbus slave 设备通过 网关thingsboard-gateway 将数据上传到thingsboard云平台

搭建thingsboard物联网云平台花了大量时间,从小白到最后搭建成功,折磨了好几天,也感谢网友的帮助,提供了思路最终成功搞定,特此记录。

一、thingsboard环境搭建(Ubuntu20.04LTS)

参考官方文档,按部就班操作即可

http://www.ithingsboard.com/docs/user-guide/install/ubuntu/

二、thingsboard-gateway环境搭建

也是参考官方文档,直接安装

Step 1. Download the deb file

|------------------------------------------------------------------------------------------------------------------|
| wget https://github.com/thingsboard/thingsboard-gateway/releases/latest/download/python3-thingsboard-gateway.deb |

Step 2. Install the gateway using apt

Install ThingsBoard IoT Gateway as package and run it as daemon use the following command:

|-------------------------------------------------------|
| sudo apt install ./python3-thingsboard-gateway.deb -y |

The deb package will automatically install the necessary libraries for the IOT Gateway to work:

  1. System libraries: libffi-dev, libglib2.0-dev, libxml2-dev, libxslt-dev, libssl-dev, zlib1g-dev, python3-dev, python3-pip.
  2. Python modules: importlib, importlib-metadata, jsonschema, pymodbus, lxml, jsonpath-rw, paho-mqtt, pyserial, PyYAML, simplejson, pyrsistent.

Step 3. Check gateway status

复制代码
systemctl status thingsboard-gateway

修改配置文件:/etc/thingsboard-gateway/config/tb_gateway.json

bash 复制代码

      }
    ]
  },

}

三、modbus slave配置

在命令行重启网关:

sudo systemctl restart thingsboard-gateway.service

云平台就会出现Modbus Temperature Sensor这个设备

四、新建调试界面,对设备进行调试

终于通信成功!!!!!
