This means performing initial data processing, filtering, or even simple decision-making closer to the data source (at the sensor or local gateway). This reduces the amount of data transmitted to the cloud, lowers latency for critical actions, and enhances system resilience.
Data Flow and Processing
The data flow within a ZX4224-based system is a continuous, cyclical process:
1. Detection: A parking sensor, connected to a ZX4224 module, detects a change in occupancy (vehicle arrival or departure).
2. Transmission: The ZX4224 module processes this event and securely transmits a small data packet (e.g., “spot ID 123, status: occupied, timestamp”) over the 4G LTE network using a protocol like MQTT.
3. Ingestion: أ IoT Hub أو message broker in the cloud receives these messages from potentially thousands of ZX4224 modules.
4. Processing: Cloud-based services (e.g., serverless functions, stream processors) ingest the data, validate it, and update the status of the corresponding parking spot in a real-time database.
5. Analytics: Background processes continuously analyze the updated data to calculate overall occupancy, identify trends, and trigger alerts.
6. Dissemination: The updated parking availability information is then made accessible via APIs to mobile applications, web dashboards, and other integrated systems, providing real-time guidance to drivers and operators.
Security Considerations in Wireless Parking
