Description

technical field

[0001] The invention relates to a data collection and storage system, in particular to a pulse-adjusted signal low-distortion wireless audio data collection and storage system. Background technique

[0002] Audio data acquisition and storage systems have been widely used in the fields of industrial automation production, national defense and military monitoring, and environmental monitoring. The audio data acquisition and storage system can continuously capture various signals or characteristic signals when a fault occurs, and store the captured signals so that relevant personnel can analyze the signals. With the development of wireless network technology, a wireless audio data collection and storage system has appeared on the market. The wireless audio data collection and storage system can save tedious line laying and save costs. However, the existing wireless audio data collection and storage system still has a big problem, that is, the collected signal i...
