6 Data Reporting Communication Protocol

6.1 

For UDP / TCP / MQTT / HTTP and other push methods, users should provide the IP address and port number of the public network of the cloud server to receive the data.

Example of JSON format:

{

"deviceId": 123456789, / / device serial number

"Flow": 11.1, / / instantaneous flow, in m³ / h

"heatFlow": 12.21, / / instantaneous heat flow, in GJ / h

"fluidSpeed": 11.1, / / fluid speed in m / s

"fluidSoundSpeed": 11.1, / / measure the sound speed of the fluid in m / s

"positiveFlow": 11.1, / / positive cumulative flow in m³

"negativeFlow": 11.1, / / negative cumulative flow, in m³

"positiveHeat": 11.1, / / positive heat accumulation in GJ

"negativeHeat": 11.1, / / negative cumulative heat, unit: GJ

"netFlow": 11.1, / / net cumulative flow, unit: m³

"netHeat": 11.1, / / net cumulative heat, unit: GJ"

"supplyTemp": 11.1, / / Water supply temperature, unit: ℃

returnTemp":11.1// Rebound temperature in ℃

}

6.2 The Protocol Receives the Test

Use network debugging assistant Net Assist.

6.3 Agreement Customization

If you need to customize other communication protocols, you can contact the business personnel to communicate.

7 Platform Docking

7.1 Default Platform

The product is connected to our designated open industrial IOT platform by default, and the platform interface is as follows:

Computer-side browser interface

Mobile terminal WeChat access interface

7.2  User Specified Platform

Take the connection of Ali Cloud platform as an example. After users create products and add devices on the Ali Cloud Internet of Things platform, users need to provide a triad: {ProductKey, DeviceName, DeviceSecret} and the MQTT theme to be released.

For example, the value of triples are:

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

 DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

Take OneNet platform docking as an example, after users create products and add devices on China Mobile OneNet platform, users need to provide product ID and and device registration code.

for instance:

ID：332590

Registration code: DGRUa7Vr9KYGunwJ
