Medical technicians in the Command Center use the EmergencyDrone application to receive requests containing all required information and to approve or reject missions. The application includes all essential functions, allowing technicians to launch missions and monitor their execution.
Medical technicians in the field use the EmergencyDrone mobile application to request a mission. First, the technician selects the required blood type and then submits the request. The application includes all essential functions, allowing the technician to monitor the drone’s flight as it transports the blood bag to the destination.
This system architecture is designed for missions that require continuous monitoring. The PR-DC drone sends telemetry and status data from its onboard controller to a PRDC_RFLink-19 module over USART, which transmits the data over a long-range LoRa link (433–915 MHz) to a ground PRDC_RFLink-19 receiver. The receiver connects via USB to an Android device running PRDC_MQTTSerialBridgeM, which securely publishes the incoming serial data to the PRDC_MQTT_BROKER (Windows, Linux, or macOS) over TCP/IP MQTT, where it can be logged and optionally exposed via a web server/WebSocket MQTT endpoint. Authorized clients, including PRDC_FlightMonitor on desktop, PRDC_FlightMonitorM on Android/iOS, and PRDC_FlightMonitorW in a browser, then subscribe to the broker to view live flight data in real time.
