Description

technical field [0001] The invention relates to the technical field of noise remote monitoring, in particular to a multi-channel noise remote wireless monitoring device. Background technique [0002] Noise exists in various places where we live, on both sides of public transportation roads, along railway lines, rail transit stations, large squares, factory buildings, etc. Studies have shown that long-term exposure to noisy environments will have an impact on our health. At present, There are two main ways to monitor noise signals: [0003] 1. Wired measurement: Use signal cables to connect the front-end acoustic sensor and data acquisition instrument together. This method requires on-site wiring. When there are multiple measurement points, a large number of signal cables will cause safety hazards to the safety of people passing by on the one hand, and too many cables entangled with each other will significantly increase the work difficulty of the measurement personnel and r...
