One of the interfaces needs to be installed on the surface of the noise monitor using at least two connecting screws, which results in more connecting screws being consumed when installing multiple interfaces. When more connecting screws are assembled at the same time, the assembly efficiency is low. Therefore, it is necessary to design an unmanned vehicle noise monitoring device that reduces the use of connecting screws. Utility Model Content

[0007] Furthermore, the upper end of the noise monitor is open, and a detachable top cover is installed on the upper end of the noise monitor. A plurality of heat dissipation fins are evenly fixed on the upper surface of the top cover, and the heat dissipation fins and the top cover are an integrally formed structure.

[0008] Furthermore, a bottom plate is connected and fixed to the bottom of the noise monitor, the width of the bottom plate is greater than the width of the noise monitor, and two fixing holes are provided on the upper surface of the bottom plate at positions on both sides of the noise monitor.
