Intelligent street lamp with impact sound detection function

Abstract

The invention discloses an intelligent street lamp with a built-in collision sound detection function. A sound collection module, a collision sound recognition module, a storage module and a street lamp controller for street lamp control and information transmission are arranged in the street lamp; the sound collection module is used for continuous collection The sound signal in the road; the storage module is used to store the sound signal collected by the sound collection module; the collision sound recognition module is used to identify whether the collected sound signal contains collision sound and send the recognition result to the street lamp controller, the street lamp control The sensor can judge whether there is an abnormal event on the road and send the information to the remote monitoring center. Adopting the technical solution of the present invention, the deep neural network is used to realize the recognition of collision sound, thereby improving the recognition accuracy of collision sound, and at the same time, the monitoring method combining audio and video is used to further improve the all-round monitoring of road safety, and can timely warn of abnormalities in road traffic event.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to an intelligent street lamp with a built-in collision sound detection function applied to road lighting. Background technique [0002] In recent years, with the maturity of cloud computing, big data, artificial intelligence, and high-performance computing hardware technology, especially the deep learning (deep learning, DL) theory in the field of machine learning and the maturity of automatic feature learning neural network models, deep neural network It has been widely used in the field of artificial intelligence (intelligent image and voice recognition), and all major IT giants regard artificial intelligence as the next core technology growth point. At the same time, the market has also spawned a large number of integrated chips with built-in deep neural network architecture, such as Nvidia (NVIDIA) launched the first chip Tesla P100 specially designed from scratch for ...
