Residential community monitoring system combining sound and video

Abstract

The invention discloses a residential community monitoring system combining sound and video. The system comprises a sound positioning module, a camera driving module, an inter-module communication interface, an audio identification module and an alarm module. The sound positioning module is used for acquiring surrounding environment sound of a community and positioning the surrounding environment sound, including microphone array and sound source position judgment; the inter-module communication interface is connected with a microphone array, a camera and an audio identification module; the audio recognition module receives the sound signals collected by the microphone array and performs abnormal sound detection on the sound signals; the camera driving module comprises a camera driving circuit and a camera, the camera driving circuit receives the recognition result of the audio recognition module, and when the audio recognition module recognizes abnormal sound, the camera driving circuit drives the camera to rotate so that the camera can be aligned with the sound source position, and meanwhile the alarm module is started to give an alarm. The problems that traditional video monitoring only has video pictures, video blind areas exist, and meanwhile sound signal collection is lacked are solved.

Description

technical field [0001] The invention belongs to the field of monitoring, in particular to a residential area monitoring system combining sound and video. Background technique [0002] In recent years, with the continuous advancement of urbanization, a large number of urban residential quarters have been newly built, which has improved the living conditions of urban residents. Due to the high density of the population, the complex composition of the residents, and the imperfect safety precautions, the community has become a high-incidence area for urban criminal cases. The security work of residential quarters is related to social harmony and tranquility. Strengthening the safety management of residential quarters will help promote the harmonious development of society, and is also of great significance to promoting the construction of a safe city. [0003] At present, the intelligent monitoring system is mainly based on the video signal, by using computer vision technology ...

AI Technical Summary

Problems solved by technology

Although there are existing monitoring systems for residential quarters on the market, these monitoring systems are relatively single, with only video monitoring terminal equipment, and there are disadvantages such as complex video image processing, large resource consumption, high price, and too much dependence on light, so it is necessary to develop A new technology that introduces voice recognition technology into video surveillance terminals, serving residential communities
