Core Business Processes

1. Device Connection Process​

User creates a gateway
        ↓
Configure basic gateway information: name, type, and project
        ↓
Gateway connects to the EMQX broker through MQTT
        ↓
Complete device authentication and establish heartbeat communication
        ↓
Gateway reports data → stored in InfluxDB
        ↓
WebSocket push → real-time display on the Web front end

2. Cloud SCADA Activation Process​

Add gateway → select Cloud SCADA activation → select license type: trial or permanent
        ↓
Trial license → automatically set trial_end_time = now + 30 days
Permanent license → trial_end_time = null
        ↓
Bind gateway data points → bind objects in the SCADA editor
        ↓
License expires → WebSocket push stops + InfluxDB storage stops

3. Data Storage Configuration Process​

Open Gateway Details → Data-Point Management
        ↓
Select the data points whose history should be stored, up to 100 per operation
        ↓
Call the /data/setStore API to save the configuration in a batch
        ↓
Data is written to InfluxDB → historical-data queries become available
        ↓
Data bucket expires → storage stops automatically

4. Remote Operations and Maintenance Process​

Operations personnel sign in to the Web management console
        ↓
Select the target gateway → open Gateway Details
        ↓
Remote configuration: push configuration through MQTT → gateway updates automatically
Firmware OTA upgrade: upload firmware package → select upgrade strategy → issue upgrade command
Remote logs: establish a WebSocket connection → stream logs in real time
Remote shell: establish a WebSocket connection → execute remote commands
        ↓
Operation result returned → log recorded
