6 Typical Application Cases

7 Data Reporting Communication Protocol

7.1

Multiple push methods such as UDP/TCP/MQTT/HTTP are available. Users need to provide the public IP address and port number of the cloud server to receive data.

Example of JSON format data message:

{"IMEI":860344048491162,"RotateSpeed":254,"ICCID":"1119205006447538"}

Message parsing:

{

"RotateSpeed":2000    // Rotational speed r/min

"ID": "860344048491162" // Device ID

}

Protocol reception test

The network debugging assistant NetAssist can be used for reception testing.

7.2 Protocol customization

If other communication protocols need to be customized, please contact the business personnel for communication.

8 Platform docking

8.1 Default platform

The product is connected to our designated open industrial Internet of Things platform by default when leaving the factory. The platform interface is as follows:

电脑端浏览器界面

手机端微信访问界面

8.2

Taking the docking with Alibaba Cloud platform as an example, after a user creates a product and adds a device on the Alibaba Cloud IoT Platform, the user needs to provide a triplet: {ProductKey, DeviceName, DeviceSecret} and the MQTT topic to be published.

For example, the values of the triplet are respectively:

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

Taking the docking with OneNet platform as an example, after a user creates a product and adds a device on China Mobile's OneNet platform, the user needs to provide the product ID and device registration code.

For example:

ID: 332590

Registration code: DGRUa7Vr9KYGunwJ

9 Installation Notes

1) The product has a built-in SIM card, and the annual data fee is about 10-20 yuan depending on the frequency of reported data. Users can also use their own SIM cards, which needs to be confirmed in advance.
