[0002] A blasting vibration meter is a portable, specialized device used for long-term on-site acquisition, recording, and storage of blasting vibration and impact signals. Traditional blasting vibration meters are modular, consisting of a data acquisition unit and sensors, requiring separate mounting of sensors in the X, Y, and Z directions during operation. The data acquisition unit connects directly to the sensors via a signal interface, is placed at the vibration test point, acquires and saves the on-site vibration signals, and connects to a PC via a communication interface after the blast.

[0003] Since the data acquisition unit and the sensors are separate units, the entire blasting vibration meter needs to be protected against water, moisture, and sunlight. If the protection is inadequate, the data acquisition unit or any of the three sensors may cause the blasting vibration meter to malfunction. Utility Model Content
