Description

Technical field [0001] The present invention relates to the field of sound test node data acquisition devices, and is specifically an intelligent sound measurement node data acquisition system. Background technique [0002] With the importance and complexity of security work, the demand for sound detection is increasing. The traditional sound node usually only has the ability to collect the sound signal acquisition ability, which constitutes a high demodation network, and the conventional sound control device has a data acquisition system usually adopts the electret capacitance microphone, which is more difficult. Miniaturization, the full-to-direction microarray sound monitoring node can meet the urgent needs of the pre-deployment and deployment, and long-term all-round arrogance. [0003] A smart sound test node is known, and it is desirable to have a long-term concealed operating ability, which can obtain sound data from the environment, and estimate the orientation of the tar...

AI Technical Summary

Problems solved by technology

Traditional acoustic measurement nodes usually only have the ability to collect acoustic signals, and require high network communication when forming an acoustic measurement sensor network, and the data acquisition system of conventional acoustic measurement devices usually uses electret condenser microphones, which are large in size and difficult to detect. Miniaturized, omnidirectional microarray acoustic monitoring nodes can better meet the urgent needs of large-scale forward deployment to fill blind spots and long-term omnidirectional approaching reconnaissance
