Wireless detonation system with dongle and trigger device
A recently granted patent (Publication Number: US11867493B2) discloses a wireless detonation system that includes a dongle for connecting to a computer system and wirelessly controlling trigger devices. The dongle communicates with trigger devices equipped with a processor, radio transceiver, communication terminals, and an electric energy storage unit for igniting detonators. The system ensures synchronization between the dongle and trigger devices by transmitting unique identifiers, allowing only authorized commands from the dongle to ignite explosive charges. The dongle can receive commands from a computer system and transmit them wirelessly to the trigger devices, initiating the detonation process by charging and discharging the electric energy storage unit.
Furthermore, the system can include multiple trigger devices connected to detonators, each activated by the electric energy storage unit. The dongle features a database storing unique trigger device identifiers, while the trigger devices and dongle are equipped with batteries and annunciators for visual and haptic feedback. The system's communication terminals can utilize Near Field Communication (NFC) or Radio Frequency Identifier (RFID) technology for contactless communication. A method for controlling detonation involves wirelessly associating trigger devices with the dongle, transmitting commands from a computer system to arm and detonate the explosive charges, and evaluating trigger device conditions before ignition. Additionally, the method includes boosting the voltage of the electric energy storage unit via a voltage booster in each trigger device before discharging for detonation, ensuring a safe and controlled detonation process.
