Problems solved by technology

[0002] At present, the pickup monitors on the market are mainly analog or digital pickups, which are bound to a single camera, or connected to a signal splitter to connect multiple cameras. Surround the camera, and the camera is installed in a position that is convenient for monitoring. Such a position is often not conducive to monitoring, so the monitoring effect is not good
[0003] With the improvement of people's requirements for security monitoring and the complex and changeable monitoring environment, such as the size of the monitoring area and the different on-site furnishings, continuous noise, sudden noise in the environment, reverberation on site, and broadcast prompts will directly affect the monitoring effect.
Moreover, most of the existing pickup monitoring solutions are independent individuals, not related to each other, and there is no way to form a pickup monitoring system, there is no way to manage and maintain them in a unified manner, and the working status of the pickups cannot be grasped in real time, and the installation location is also limited. , unable to meet the actual needs of audio monitoring and video monitoring

Embodiment 1

[0043] The types of the plurality of pickups include but are not limited to one or more of analog pickups, digital pickups, and array pickups. At this time, some front-end pickups have real-time noise reduction and reverberation suppression functions, and the audio signal output to the pickup gateway is the sound signal after noise reduction and reverberation suppression. If the front-end pickups do not have real-time noise reduction and reverberation suppression functions, Then the transmission signal is an audio signal collected by the pickup in real time.

[0044] Correspondingly, such as figure 2 As shown, the pickup gateway includes a power supply module and a network transmission switching module, a signal processing control module, a noise reduction and filtering module, and a codec conversion module that are all powered by the power supply module;

[0045] The network transmission switching module is electrically connected with the front-end sound pickup equipment an...

Embodiment 2

[0050]The type of the plurality of pickups is an IP pickup; since the IP pickup is adopted, there is no need to convert the IP stream code, so the pickup gateway of this embodiment only needs to include a power supply module and a network transmission switching module and a signal processing module powered by the power supply module. Control module, noise reduction and filter module; compared with the above-mentioned embodiment 1, the codec conversion module can be omitted.

[0051] As a supplement to the above two embodiments, the pickup gateway further includes a remote reset switch electrically connected to the signal processing control module, and the remote reset switch is used to reset the audio signal IDs of the plurality of pickups. You can also reset the reset switch in the gateway settings on the server. After the reset, the ID will be re-assigned, and the corresponding server mapping ID will be refreshed.

[0052] Another innovative point of the technical solution i...

Embodiment 3

[0069] By selecting the designated ID pickup audio signal on the pickup management system and combining it with the current video surveillance signal, a final audio and video file is output. When the audio or video information in the file cannot meet the technical protection requirements (the sound is not clear or the video No angle, not enough clarity), you can choose other assembly methods; you can manually select a recording file at a specific location through the pickup distribution map on the pickup management system and video surveillance for assembly. The assembly process can realize pause, play, Fast forward, fast rewind and other functions are available for management personnel to listen to recording files and view video content, which is convenient for management personnel to make optimal configuration solutions; when the video has no angle or is unclear, it can be recorded through other path video files on the DVR Call, the pickup management system selects the video ...

Abstract

The invention discloses a pick-up system audio monitoring method and a pick-up system audio monitoring device. The device comprises front-end pick-up equipment that comprises multiple pick-ups distributed at different positions of the scene as required; a pick-up gateway used for performing recognition, optimization and ID distribution on the audio signal; a switch that is connected between the pick-up gateway and a computer server, and used for transmitting an audio signal processed by the pick-up gateway; and the computer server used for storing and managing audio signals collected by the front-end pick-up equipment according to the ID. Various kinds of pick-up signals are converted in real time via the pick-up gateway, and access IDS are compiled to map the accessed pick-ups to server management software, assembly of audio monitoring and video monitoring of the target position is achieved in combination with video monitoring, a high-quality and high-definition record can be selectedfor outputting and combining with a video, and thus the technical problems that the mutual independent resources of the front-end pick-up are not unified, and the matching of the video signal and theaudio signal is single are solved.

Description

technical field [0001] The invention relates to the field of audio monitoring, in particular to an audio monitoring method and device for a sound pickup system. Background technique [0002] At present, the pickup monitors on the market are mainly analog or digital pickups, which are bound to a single camera, or connected to a signal splitter to connect multiple cameras. It is necessary to surround the camera, and the camera is installed in a position that is convenient for monitoring. Such a position is often not conducive to monitoring, so the monitoring effect is not good. [0003] As people's requirements for security monitoring increase and the monitoring environment is complex and changeable, such as the size of the monitoring area and the site layout, the continuous noise of the environment, sudden noise, reverberation, and broadcast prompts will directly affect the monitoring effect. Moreover, most of the existing pickup monitoring solutions are independent individu...
