Abstract

The invention discloses a wireless audio data collection and storage system with low signal distortion, which is characterized by mainly consisting of a first single chip, a second single chip, a first wireless transceiver module and an analog-to-digital conversion unit, which are separately connected with the first single chip, a signal collector connected with the analog-to-digital conversion unit, a signal processing unit and a memory, which are separately connected with the second single chip, and a second wireless transceiver module connected with the signal processing unit. The wireless audio data collection and storage system disclosed by the invention can process an audio signal, so that the fidelity of the audio signal stored in the wireless audio data collection and storage system is higher, and thus the stored audio signal can really reflect the situations of a monitoring site.

Description

technical field [0001] The invention relates to a data collection and storage system, in particular to a low signal 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 is easily mixed ...
