v Support any Internet of Things cloud platform and configuration software, and provide data protocol docking.
v Support Ali Cloud, Baidu Tiangong, OneNet, Tencent Cloud and other mainstream cloud platforms.
v Non-invasive collection, does not affect the normal operation of the equipment.
v Support remote configuration parameters and FOTA remote upgrade to minimize the personnel cost of site construction and maintenance.
6 Data Reporting Communication Protocol6.1 Protocol Parsing InstructionsFor 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 TestUse network debugging assistant Net Assist.
6.3 Agreement CustomizationIf you need to customize other communication protocols, you can contact the business personnel to communicate.
7 Platform Docking7.1 Default PlatformThe 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 PlatformTake 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
