Acoustic signal collection device of elevator and working method thereof

Abstract

The invention relates to an acoustic signal collection device of an elevator, and a working method of the acoustic signal collection device of the elevator. According to the integrated acoustic signal collection device of the elevator, and the working method of the acoustic signal collection device of the elevator, acoustic signals and visual signals are integrated, related electronic circuits or devices or facilities do not need to be added to a display device of the elevator. The problem that in the prior art, acoustic signal collection needs to depend on cooperation among a hardware collection device, a physical connection circuit and an external loudspeaker box, or acoustic signal collection is achieved by needing to depend on a control system communication protocol is solved. The acoustic signal collection device of the elevator comprises a central processing unit, wherein the central processing unit is connected with an elevator communication management module, and is further connected with a Flash visual sense storage module and a writable auditory sense storage module. The central processing unit drives a liquid crystal display screen and a built-in loudspeaker through a driver module and a voice standalone respectively, wherein the liquid crystal display screen and the built-in loudspeaker are installed in the elevator.

Description

technical field [0001] The invention relates to an elevator auditory signal acquisition device and a working method thereof. Background technique [0002] Elevator users usually hope to obtain dual visual and auditory signals when taking the elevator, so as to perceive the operating status and location information of the elevator. In some special or emergency situations, such as elevators used in barrier-free places and elevators with trapped people, having auditory and visual signals is an important embodiment of the human-oriented design concept, and it is also one of the necessary safety technical measures for elevators. Part 70 of EN81-70:2003 "Safety Code for Manufacture and Installation of Elevators", Part 70 of Special Applications for Passenger Elevators and Freight Elevators: Including the Accessibility of Elevators Used by Disabled Persons and GB / T24477-2009 "Applicable to Disabled Persons" This is clearly stipulated in Chapter 5 of the Additional Requirements for...

AI Technical Summary

Problems solved by technology

[0008] 1. The first type of existing technology: there must be hardware devices and physical connections specially for collecting auditory signals. As the elevator runs up and down, the movement of these devices and the repeated bending of the connections can easily cause short circuits, short circuits and contact failures. , resulting in an increase in elevator failures and even becoming the source of accidents

Not only does it cause safety hazards to the elevator operation, but it also increases the purchase cost of the elevator and brings more troubles to maintenance.

[0009] 2. The second type of existing technology: because there are many types of control system protocols, manufacturers generally do not open them, so the compatibility of such products is not good, which limits the general promotion, which forms an obstacle for emergency rescue or remote monitoring

For example, if there are elevators manufactured by different manufacturers in a community, it is difficult to realize the intelligent centralized management of the elevators in the whole community due to the different communication.

Therefore, the maintenance and management costs are high

By extension, if it is enlarged to a larger area, this "information island" will make the social management cost of elevators difficult to estimate
