Abstract

The invention discloses a wireless audio data acquisition and storage system. The system is characterized by mainly comprising a first single-chip microcomputer, a second single-chip microcomputer, a first wireless receiving and transmitting module and an analog-to-digital conversion unit which are connected with the first single-chip microcomputer, a signal acquisition device connected with the analog-to-digital conversion unit, a signal processing unit and a storage device which are connected with the second single-chip microcomputer, as well as a second wireless receiving and transmitting module connected with the signal processing unit. With the system, audio signals can be processed, so that the fidelity of the audio signals stored in the system is higher, and the stored audio signals can reflect conditions of a monitoring field truly.

Description

technical field [0001] The invention relates to a data collection and storage system, in particular to a 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 with interference sign...
