Pulse regulation type signal low-distortion wireless audio data collection and storage system

Abstract

The invention discloses a pulse regulation type signal low-distortion wireless audio data collection and storage system, which is characterized by mainly comprising a first single-chip microcomputer, a second single-chip microcomputer, a first wireless transmitting and receiving module, an analog-to-digital conversion unit, a signal collector, a signal processing unit, a memory and a second wireless transmitting and receiving module, wherein the first wireless transmitting and receiving module and the analog-to-digital conversion unit are connected with the first single-chip microcomputer, the signal collector is connected with the analog-to-digital conversion unit, the signal processing unit and the memory are connected with the second single-chip microcomputer, and the second wireless transmitting and receiving module is connected with the signal processing unit. The system disclosed by the invention can perform processing on audio signals, the fidelity of the audio signals stored by the system is enabled to be higher, and thus the stored audio signals are enabled to truly reflect condition of the monitoring field.

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...
