Problems solved by technology

Because most of the prison staff are restless people, there will often be fights due to minor differences of opinion, and many of them can avoid the monitoring system, fight in the blind spot of monitoring or when they fight, the prison guards are not aware of it. Real-time attention to the monitoring screen makes it difficult for prison guards to obtain information in a timely manner in many cases, and to stop the scene is only known after the fact

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1~2 As shown, a recognition device for fighting in a prison includes: a storage module, which is a hard disk or a cloud disk, and is used to store a fighting audio database containing characteristic audio of a prison fight; an audio collection module is used for real-time collection of audio in a prison scene ; The algorithm detection module is used to extract the audio features in the prison scene, and compare the similarity with the feature audio of prison fights in the fight audio database, determine whether it is a fight audio and call the police in time.

[0023] Preferably, the audio collection module is composed of a microphone array and a pickup. The microphone array can perform the functions of identifying the direction of the sound source and reducing noise. The pickup can remotely acquire the sound of...

Abstract

The invention relates to an identification device and method for a prison fight. The identification device for the prison fight includes a storage module, an audio acquisition module and an algorithmdetection module. The identification method includes: establishing a fight audio database in the storage module, wherein the fight audio database includes feature audios of prison fights; acquiring anaudio in a prison scene is by the audio acquisition module, performing feature extraction on the prison audio, and performing similarity comparison on the extracted prison audio features and the feature audios of the fight audio database; setting a similarity threshold in the algorithm detection module, performing feature extraction on the audio in the prison scene, and performing similarity comparison on the features and the prison fight feature audios in the fight audio database, determining if the similarity reaches the threshold or not, and determining that the audio is a fight audio andissuing an alarm. The identification device and method for the prison fight can accurately diagnose the presence of fight behaviors in the prison and issue an alarm by analyzing, identifying and locating the audio in the prison scene.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to a recognition device and method for prison fights. Background technique [0002] Prison refers to the place where criminals sentenced to death with a two-year suspension of execution, life imprisonment, or fixed-term imprisonment execute their sentences in accordance with the provisions of the Criminal Law and the Criminal Procedure Law. Implement the principle of combining punishment with reformation, education and labor, and transform criminals into law-abiding citizens. Because most of the prison staff are restless people, there will often be fights due to minor differences of opinion, and many of them can avoid the monitoring system, fight in the blind spot of monitoring or when they fight, the prison guards are not aware of it. Real-time attention to the monitoring screen makes it difficult for prison guards to obtain information in a timely manner in many ca...
