Specifically, the display unit 320 includes a display, and the display is disposed on an outer wall of the storage box 400. Of course, the display may be fixed to the outer wall of the storage box 400, or may be hinged to the outer wall of the storage box 400.

When the display is hinged with the outer wall of the receiving box 400, the angle of the display with the outer wall of the receiving box 400 can be adjusted. At this moment, when the observer is obtaining the video data of the water gauge, referring to fig. 15, the included angle between the outer wall of the adjusting display and the outer wall of the containing box 400 is greater than 90 °, so that the observer can conveniently watch the obtained video data. When the video data of water gauge need not be acquireed, see fig. 6 and fig. 7, with display and containing box 400 lock, can reduce water gauge reading system's volume, avoid the protection screen to receive the damage.

Specifically, referring to fig. 14, the intelligent recognition module 300 further includes a storage unit 330, and the storage unit 330 is connected to the analysis unit 310 and the display unit 320 through a bus 340; the storage unit 330 is used to store valid video data. At this time, when the inspector disputes the water gauge reading obtained by identification at a later stage, the valid video data in the storage unit 330 can be called out for identification again.

Further, the storage unit 330 may be a storage device, or may be a collective term for a plurality of storage elements, and is used for storing executable program codes and the like. And the memory may include a Random Access Memory (RAM) or a non-volatile memory (non-volatile memory), such as a magnetic disk memory, Flash memory (Flash), etc.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
