Embodiment 1
[0026] Embodiment 1, with reference to attached figure 1 .
[0027] This embodiment provides an elevator platform detection system based on audio analysis. The detection system includes an audio collection unit 1 , an audio analysis unit 2 , an audio comparison unit 3 and an alarm unit 4 .
[0028]Among them, the audio collection unit 1 collects the sound information in the elevator car in real time, the sound information especially includes human voice and other sounds from the human body, in addition to all the sounds that can be collected when the elevator car is running. Sound, the human voice is usually made by the elevator passengers. Generally speaking, the passengers in the elevator will not make too many decibel sounds. Normal conversations or silent or human movements can be used as friction sounds. Human voices are collected. When special situations occur in the elevator car, such as abnormal operation of the car causing shock or even injury to passengers, or dispu...
Embodiment 2
[0036] Embodiment 2, with reference to attached figure 1 .
[0037] The method utilizes the detection system described above and includes the following steps:
[0038] S1, collect the sound signal in the elevator car in real time through the audio acquisition unit installed in the elevator car and send it to the audio analysis unit;
[0039] S2. The audio analysis unit analyzes the sound signals collected by the audio acquisition unit in real time. The analysis results include two types of sound information, namely, there are passengers in the elevator and there are no passengers in the elevator. The analysis results are sent to the audio comparison unit; specifically, the audio The analysis of the collected sound information by the analysis unit includes:
[0040] S2.1, perform noise separation on the collected sound information, extract the elevator running noise and other audio signals separately, and classify and mark them,
[0041] S2.2, perform audio frequency spectru...

Abstract
The invention provides an elevator platform detecting system based on audio analysis. The elevator platform detecting system comprises an audio collecting unit, an audio analyzing unit, an audio comparing unit, a data analyzing unit and an alarming unit. The audio collecting unit sends collected sound information to the audio analyzing unit which carries out technical analysis on the sound information to obtain information of various sounds in an elevator car, and the audio analyzing unit then sends corresponding information to the audio comparing unit. The audio comparing unit carries out analysis and comparison by combining analysis results and a comparison foundation of a big data platform, the data analyzing unit judges whether an alarm needs to be given out or not according to analysis and comparison results, and the alarming unit is used for sending corresponding alarming information to the outside. The invention further provides an elevator platform detecting method based on audio analysis. By means of the elevator platform detecting system and method, operation conditions of an elevator and using conditions of passengers in the elevator can be monitored and judged in real time, rescue efficiency is improved, and the using safety of the elevator is improved to a large extent.
Description
technical field [0001] The invention relates to the technical field of audio analysis and the technical field of elevator safety. Background technique [0002] With the continuous improvement of the degree of modernization of life and the continuous improvement of resource utilization requirements, high-rise buildings are increasingly occupying a dominant position in modern life and office buildings due to their advantages such as high land utilization. Generally speaking, buildings with more than 7 floors require Equipped with car elevators, that is to say, car elevators are more and more integrated into people's daily life. Generally speaking, more than 70% of people living in cities need to take car elevators every day. Regarding the car-type elevator, people are most concerned about the safety of the elevator. Due to technical and cost problems, the maintenance of the elevator is usually carried out on a regular basis. The current requirement is to perform maintenance at...
