Problems solved by technology

The disadvantages of the indicator light display are: the displayed information is too little, not intuitive enough, and not clear enough, and it is easy to be ignored in the chaos of a fire; It can display two or four Chinese characters at the same time, and it takes multiple screen swipes to fully express the meaning of "the elevator has made an emergency landing when the fire broke out, please evacuate from the safe passage"; The elevator should be forced to land and stop using, and the scene may be full of smog, which may affect the visual judgment of details. Coupled with the panic in emergency escape, many people may ignore the existence of the prompt information, and wait for a long time for the elevator to arrive, wasting precious escape time. Increased casualties in fires

Abstract

The invention discloses a sound-video frequency equipment of elevator fire-fighting state information, which is characterized by the following: possessing larger display area; feeding back the visual information to the passenger; adapting loudspeaker to feed back the acoustic information to the passenger; making the passenger abandon the elevator coming; leaving through the safe path; reducing the personnel casualty.

Description

technical field [0001] The invention relates to an audio and video display device installed in a passenger elevator car or an elevator front room for displaying the elevator fire protection working state, and belongs to the technical field of fire alarm. Background technique [0002] Passenger elevators in high-rise buildings belong to the key parts of fire safety: when a fire occurs, flames and thick smoke are easy to spread upward along the elevator shaft, invading the elevator car or causing elevator failure, causing casualties; When a fire occurs, the fire alarm system or the fire alarm button set in the front room of the elevator should send an emergency landing signal to the elevator electrical control box, and the control box will no longer accept the call signal of the elevator call button on each floor, but directly force-land the elevator car on the first floor of the building ; At this time, people on all floors of the building should evacuate quickly through safe...
