Abstract

The invention provides an escalator accident automatic voice brake device. According to the escalator accident automatic voice brake device, the connecting wire ends of voice sensors mounted on the left side and the right side of an escalator are connected with an or circuit, a signal processing circuit, a voice emotion recognition circuit and a summing unit in series through wires, and the summing unit is connected with an escalator stop circuit and a loudspeaker in parallel. A volume average value circuit and a comparator are connected in series by arranging another wire on the wire for connecting the signal processing circuit with the voice emotion recognition circuit, and are connected with the summing unit. During operation of the escalator after mounting, once the escalator gets an accident, the circuits of the escalator can be disconnected automatically to stop the escalator operating via voice calls for help.

Description

technical field [0001] The invention relates to an automatic braking device which can be installed on an escalator, in particular to an automatic braking device for an escalator accident voice. Background technique [0002] In many public places such as supermarkets, shopping malls, and hotels, escalators are installed to make it easier for the public to go up and down floors. Due to the continuous operation of escalators and the different uses of the public, it is easy to cause accidents in elevators, which are unpredictable. Will directly cause personal injury. Contents of the invention [0003] The invention provides an accident voice automatic braking device of an escalator, which can allow the escalator to automatically cut off the power supply to stop the elevator running when an accident occurs. [0004] An escalator accident voice automatic braking device, including a sound sensor, a comparator, an adder and a loudspeaker, is characterized in that: the connection ...
