Embodiment 1

[0020] Such as figure 1 As shown, the elevator car safe operation system provided by this embodiment includes

[0021] An elevator car running control unit 2 for switching the running state of the elevator car;

[0022] A central processing unit 1 for controlling the elevator car operation control unit 2;

[0023] An audio decibel meter 3 for detecting the audio intensity in the elevator car;

[0024] And a comparator 4 that can compare the audio intensity detected by the audio decibel meter 3 with its preset standard value, and after judgment, send an electrical signal to the central processing unit 1;

[0025] The above-mentioned audio decibel meter 3 is connected with the signal of the comparator 4, and the above-mentioned comparator 4 is connected with the signal of the central processing unit 1, and the central processing unit 1 is connected with the signal of the elevator car operation control unit 2 again.

[0026] This embodiment also provides a method f...

Embodiment 2

[0029] The elevator car safe operation system provided by this embodiment has a general structure consistent with that of Embodiment 1, as figure 2 shown, but in order to also realize self-alarming when the central processing unit sends a stop operation instruction to the elevator car through the elevator car operation control unit 2, the above-mentioned central processing unit 1 is also connected with an alarm 5; By manually resetting the central processing unit 1 so as to switch the electric signal sent to the elevator car operation control unit 2, thereby quickly changing the running state of the elevator car, the above-mentioned central processing unit 1 is also signally connected to an interrupt switch 6 .

Abstract

The invention discloses a lift car safe operation system and method in the technical field of safety of lift cars. The system comprises a lift car operation control unit used for switching the operation states of a lift car, a central processing unit used for controlling the lift car operation control unit, a voice frequency decibelmeter used for detecting the voice frequency intensity in the lift car, and a comparator capable of comparing the voice frequency intensity detected by the voice frequency decibelmeter with a preset standard value and sending electric signals to the central processing unit after conducting judgment, wherein the voice frequency decibelmeter is in signal connection with the comparator, the comparator is further in signal connection with the central processing unit, and the central processing unit is further in signal connection with the lift car operation control unit. The lift car safe operation system and method solve the technical problem of safe operation of the lift car. The lift car adopting the operation system can stop operating automatically after passengers in the lift car shout in an emergency or danger.

Description

technical field [0001] The invention relates to an elevator car safety operation system in the elevator car safety technical field, and an operation method of the elevator car safety operation system. Background technique [0002] As we all know, elevators have become a part of people's modern life, and whether the elevator car can run safely is directly related to the safety of people's lives and properties. [0003] At present, the existing elevator car running system often has safety function modules such as elevator car overload protection and elevator car speed limit protection. However, when people encounter emergency or dangerous situations when using the elevator car, for example, when people's hands or certain parts of the body are caught by the elevator car door or the elevator landing door, the above-mentioned safety function modules cannot protect people's lives. safe role. Contents of the invention [0004] The purpose of the present invention is to solve th...
