Induction blind way brick, trigger type blind stick, blind way cooperative system

Abstract

The application relates to the technical field of intelligent traffic equipment, in particular to an inductive blind sidewalk brick, a trigger type blind stick and a blind sidewalk coordination system. The inductive blind sidewalk brick comprises a blind sidewalk brick body, a trigger device and an inductive device; the blind sidewalk brick body is internally formed with a cavity; the trigger device is arranged on the blind sidewalk brick body and receives a trigger signal of short-distance wireless induction triggering; the inductive device is arranged in the cavity and is signal-connected to the trigger device; the inductive device sends an alarm signal after the trigger device receives the trigger signal; wherein the trigger device is a blind stick trigger device; the trigger signal of short-distance wireless induction triggering is sent by the blind stick. In the application, a point-to-point identification relationship is established by close-range induction (magnetic, metal, radio frequency), so that only the blind sidewalk brick responds when a visually impaired person carrying the blind stick arrives; the selective triggering suppresses the broadcast flooding caused by scene noise (raindrops, footsteps, baby strollers and the like), thereby avoiding information fatigue and urban noise pollution.
