[0029] The working module includes a data acquisition module, a signal processing module and a control module which are respectively arranged in the chassis, and the control module is respectively connected to the data acquisition module and the signal processing module.

[0030] Specifically, the bottom plate 11, top plate 12, left side plate 13, right side plate 14, front panel 15 and rear panel 16 are all rectangular plates. When the chassis is installed, the bottom plate 11, top plate 12, front panel 15 and rear panel 16 are connected end to end in sequence to form a rectangular frame structure, and are detachably connected at the first flange 111 and the second flange 151 through the connecting plate 17 and fasteners; at the same time, the first flange 111 and the second flange 151 connected end to end also form a retaining edge structure, and the left side plate 13 and the right side plate 14 can be detachably covered on the retaining edge structure (that is, the two ends of the above-mentioned frame structure) through fasteners, thereby forming a chassis 1 structure that can be completely disassembled.

[0031] An acoustic analyzer of the present invention integrates a data acquisition module, a signal processing module and a control module in a chassis 1. Compared with the original mode of independently installing each module, it can not only reduce the occupation of the working space, but also reduce the layout complexity of the connecting lines between the modules, which can reduce the cost of installation and maintenance, and is also conducive to improving the working stability and reliability of the device; at the same time, the provision of a chassis 1 structure that can be completely disassembled further improves the convenience of installation and maintenance of the entire equipment, and has high practicality.

The signal processing module and control module are located on either side of the chassis 1. The signal processing module integrates a digital signal processor for real-time analysis and processing of collected acoustic data. The control module is responsible for overall control and status monitoring of the device. Preferably, each module utilizes a standardized interface design, further facilitating module replacement and maintenance.

A space is formed between the partition and the left side panel 13 or the right side panel 14 connected to the sidewall structure, and a wire routing slot is defined in the partition. It is conceivable that the space formed between the partition and the left side panel 13 or the right side panel 14 can be used as a routing space for connecting wires within the chassis 1, facilitating subsequent maintenance.

[0038] Furthermore, a plurality of wire holes are formed on the bottom plate 11 and the top plate 12 .

[0039] Reference Figure 2 As shown, further, two handles 19 are connected to the top plate 12 at intervals.

[0040] Furthermore, the chassis 1 can be designed with the size of a 3U standard chassis, so that the chassis 1 and the entire device can perfectly match various industrial cabinets, thereby improving the versatility and installation convenience of the equipment. Example 2
