Problems solved by technology
[0005] The beneficial effects of the present invention are: through the above-mentioned technical scheme, when the elevator is in normal operation after installation, if an accident occurs and the person sends out a voice calling for help, the operating circuit will be disconnected immediately and an alarm will be issued through the loudspeaker, thus solving the problem of the current escalator. During operation, if accidents are not handled in time, it is easy to cause personal injury. The design is scientific and the operation is sensitive after installation, which is conducive to providing safety protection for the public.

Embodiment Construction
[0009] figure 1 Shown: for the escalator accident automatic braking device installed on the left and right sides of the escalator, the connection end of the sound sensor 1 is connected in series with the OR circuit 2, the signal conditioning circuit 3, the voice emotion recognition circuit 9 and the addition through the wire 10 Device 8 is connected in parallel with elevator stop circuit 6 and loudspeaker 7, and on the wire 10 connected to signal conditioning circuit 3 and speech emotion recognition circuit 9, wire 10 is additionally set up in series with volume mean value circuit 4 and comparator 5 to communicate with adder 8 .
[0010] The working principle of the present invention is as follows: under the normal operation of the escalator, the tone of the people on the elevator is gentle, the voice volume is not high, and the electrical signals output by the left and right sound sensors 1 are relatively small, which are arranged by the OR circuit 2 and the signal conditioni...

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] The present invention includes a sound sensor, a comparator, an adder and a loudspeaker, and the adopted technical solution is: the connecting wire ends of the sou...
