Abstract
This invention discloses a control method, system, device, and equipment for underground information and warning screens based on radar waveform state recognition. Applied to the field of data processing technology, the control system is built around radar waveform segmentation recognition, FPGA / MCU dual-control arbitration, and non-blocking scheduling. Through millimeter-wave radar acquisition and dual-mode waveform recognition, accurate alarm state determination is achieved, reducing false triggering. A stable determination and takeover hold mechanism enables oscillation-free switching between dual controls, eliminating control conflicts. When the MCU takes over, display resynchronization is performed to eliminate anomalies such as ghosting and misalignment. A unified state machine enables audio-visual coordinated triggering, and Tick non-blocking scheduling ensures the parallel real-time performance of multiple tasks. Finally, alarm gating, takeover hold, and failure reset form a closed-loop control, achieving low false triggering, seamless switching, and stable and reliable full-process control of the underground warning screen.
