The Role of the ZX4224 in Data Flow

The **ZX4224** acts as the crucial **communication gateway**, bridging the local barrier gate intelligence with the remote central management system. The data flow typically follows this pattern:

1. **Local Processing**: The barrier gate’s controller unit continuously monitors sensors and access control devices. When an event occurs (e.g., a vehicle detected, an RFID card scanned, an ANPR image captured, a payment initiated), the controller processes this local information.
2. **Data Transmission**: The controller unit then sends relevant data (e.g., timestamp, vehicle ID, entry/exit status, payment details, fault codes) to the **ZX4224** module via its serial (UART) or USB interface.
3. **Cloud Connectivity**: The **ZX4224** establishes and maintains a **4G LTE connection** to the internet. It encapsulates the data received from the controller and transmits it securely to the designated **cloud server** or central management platform using protocols like **MQTT**, **HTTP/S**, or **CoAP**.
4. **Remote Commands and Updates**: Conversely, the central management platform can send commands (e.g., remotely open/close barrier, update access permissions, push firmware updates, retrieve diagnostic information) back to the barrier gate. These commands are received by the **ZX4224** via the 4G network and then forwarded to the controller unit for execution.
5. **Real-time Alerts**: In case of a malfunction, security breach, or other critical event, the controller can instantly trigger an alert through the **ZX4224** to the cloud, notifying operators for immediate action.
