Subway platform safety monitoring method based on voice recognition

Abstract

The invention discloses a subway platform safety monitoring method based on voice recognition, and mainly relates to the technical field of data services. The sound collection step comprises the steps: S11, installing sound collection devices in different areas of a platform; S12, acquiring surrounding sound in real time by using the sound collection devices; S13, filtering out the sound broadcasted by the subway station in the sounds collected by the sound collection devices, and then transmitting the filtered sounds to a sound recognition step; the voice recognition step comprises the following steps: S21, establishing a normal voice data set; S22, establishing an abnormal distress call sound data set; S23, building a voice recognizer with a call-for-help voice recognition model; S24, training the call-for-help voice recognition model; and S25, identifying the sound transmitted by the sound collection devices by using a sound identifier; according to the invention, the problems of shielding of the camera, poor image quality and inaccurate identification caused by video dead angles are solved, and the installation and maintenance cost is lower.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a sound recognition-based subway platform safety monitoring method. Background technique [0002] As a low-cost, high-efficiency, comfortable and safe travel mode in the city, subway travel is the preferred means of transportation for ordinary people. Because many people choose to travel by subway, subway trains are crowded public gathering places. Especially in the morning and evening peak hours of work, when people go out to play on holidays, when bad weather affects other travel methods, and during the Spring Festival travel season, there will be a large number of people in subway stations. Once explosions, poisonous gas, fires, stampedes and other emergencies occur, mass deaths and mass injuries will occur. or heavy losses, seriously affecting social order and stability. [0003] How to timely and effectively identify the dangerous status of personnel on the subway pla...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the problems existing in the prior art, and provide a method for monitoring subway platform safety based on sound recognition, which can not only identify dangerous events (clamping people) between the train and the platform door gap, but also Identify dangerous events in rail trains and on platforms, which solves the problem of inaccurate recognition caused by blocked cameras, poor picture quality, and video blind spots, and lower installation and maintenance costs
