Abstract

The invention discloses remote emergency broadcasting equipment for rail transit. Equipment body and horn, wherein the front surface of the equipment body is fixedly connected with the back surface ofa loudspeaker, the front surface of the equipment body is fixedly connected with a protective frame through bolts, a connecting groove matched with the loudspeaker is formed in the protective frame,and bird repelling mechanisms are fixedly connected to the side walls in the two first mounting grooves. The invention discloses remote emergency broadcasting equipment for rail transit. Bird repelling mechanisms are arranged on the two sides of the protection frame. An infrared sensor arranged on the bird repelling mechanism is used for acquiring information of birds close to the periphery of theprotection frame; and then ultrasonic waves are generated through an ultrasonic generator arranged in the bird repelling mechanism, birds near the protection frame are repelled, the phenomenon that birds nest on the broadcasting equipment is effectively avoided, a good protection effect is achieved on the broadcasting equipment, and daily normal use of the emergency broadcasting equipment is guaranteed.
