HJ212-2017 is an IoT standard outlining data transmission between pollution monitoring systems and environmental agencies.

The Neuron HJ212-2017 plugin collects data from devices supporting this standard, with the current version supporting only active data uploads.

Add Device

Go to Configuration -> South Devices, then click Add Device to add the driver. Configure the following settings in the popup dialog box.

  • Name: The name of this device node.
  • Plugin: Select the HJ212-2017 plugin.

Device Configuration

After clicking Create, you will be redirected to the Device Configuration page, where we will set up the parameters required for Neuron to establish a connection with the northbound application. You can also click the device configuration icon on the southbound device card to enter the Device Configuration interface.

Physical LinkChoose Serial or TCP connection mode.
Serial DeviceOnly for Serial mode, use a serial device, e.g. /dev/ttyUSB0
Stop BitsOnly for Serial mode, stop bits, default 1
ParityOnly for Serial mode, parity bit
Baud RateOnly for Serial mode, baud rate, default 9600
Data BitsOnly for Serial mode, byte size, default 8
IP AddressOnly for TCP mode.
When Neuron is used as a client, fill in the IP of the remote device.
When Neuron is used as a server, fill in the IP of Neuron locally, can be filled in by default.
PortOnly for TCP mode.
When Neuron is used as a client, fill in the TCP port of the remote device.
When Neuron is used as a server, fill in the TCP port of Neuron.

Configure Data Groups and Tags

After the plug-in is added and configured, the next step is to establish communication between your device and Neuron by adding groups and tags to the Southbound driver.

Once device configuration is completed, navigate to the South Devices page. Click on the device card or device row to access the Group List page. Here, you can create a new group by clicking on Create, then specifying the group name and data collection interval.

Upon successfully creating a group, click on its name to proceed to the Tag List page. This page allows you to add device tags for data collection. You'll need to provide information such as the tag address, attributes, and data type.

For information on general configuration items, see Connect to Southbound Devices. The subsequent section will concentrate on configurations specific to the driver.
