Abstract
Description
Technical Field
[0001] This application belongs to the field of urban rail transit monitoring technology, and specifically relates to a network management and monitoring system and method for urban rail transit microphones based on voiceprints. Background Technology
[0002] In currently operational urban rail transit lines, according to the requirements of public security and operation management departments, video surveillance systems need to have video playback and audio monitoring functions. The microphone equipment is primarily sourced externally by video manufacturers, and audio and video synchronization is achieved through interconnection with the front-end cameras via audio interfaces. However, because current video surveillance systems cannot manage the front-end equipment, and the microphones are externally sourced, the video surveillance system cannot centrally manage the microphones. If a microphone is offline or malfunctions, audio will be lost from the video image for an extended period, causing inconvenience for later evidence collection and maintenance management.
[0003] like Figure 1 The front-end equipment of the urban rail transit video surveillance system consists of microphones and cameras. The audio and video information is aggregated by a switch and transmitted to a video server for storage. The network management terminal is responsible for collecting fault information from the video server and offline information from the switches and cameras. Microphone fault information is not currently being collected; microphone faults can only be detected manually by reviewing the video footage.
[0004] According to the needs of public security departments for investigation and evidence collection and subway operation departments for management, video surveillance systems need to be equipped with microphones to achieve audio and video image acquisition. However, the following problems exist: First, because video surveillance system manufacturers mainly use external microphones, and the video surveillance system cannot manage the front-end equipment, microphone malfunctions cannot be detected in time, resulting in the loss of audio recordings in audio and video images; Second, there are many factors that can cause microphone malfunctions, and after a microphone malfunction is detected, it is not possible to determine the cause and location of the malfunction in a timely manner, resulting in the inability to quickly recover audio recordings from audio and video images. Summary of the Invention
[0005] To address the aforementioned issues, this application provides a voiceprint-based urban rail transit microphone network management and monitoring system and method. This system enables microphone fault management, analyzes and judges the causes and locations of microphone faults, and clarifies the causes and locations of faults. It not only solves the microphone operation and maintenance problem but also ensures the integrity of audio and video images, providing evidence for public security departments to investigate and collect evidence.

[0007] Optionally, comparing the voiceprint information with the fault voiceprint feature database includes: Receive voiceprint information uploaded by the voiceprint analysis and acquisition device; The voiceprint information is compared with the voiceprint feature database. If the voiceprint information matches the fault voiceprint feature database, the voiceprint analysis result is abnormal, indicating that the microphone is faulty, and the fault location is further determined. Otherwise, the microphone is considered to be working normally.
[0008] Optionally, further determining the fault location includes: If the camera's voiceprint analysis results are found to be abnormal, the fault location is determined to be a microphone malfunction.

[0011] Optionally, comparing the voiceprint information with the fault voiceprint feature database includes: Receive voiceprint information uploaded by the voiceprint analysis and acquisition device; The voiceprint information is compared with the voiceprint feature database. If the voiceprint information matches the fault voiceprint feature database, the voiceprint analysis result is abnormal, indicating that the microphone is faulty, and the fault location is further determined. Otherwise, the microphone is considered to be working normally.
[0012] Optionally, further determining the fault location includes: If the camera's voiceprint analysis results are found to be abnormal, the fault location is determined to be a microphone malfunction. If the voiceprint analysis results of the switch are found to be abnormal, then the camera is judged to be faulty by manual means in conjunction with the video surveillance system. If the server's voiceprint analysis results are found to be abnormal, then the switch port is checked manually in conjunction with the switch network management system to determine if it is faulty. If the voiceprint analysis results of the camera, switch, and server are all normal, then the network management information alarm should be used to determine whether the recording storage device is abnormal.
