[0018] Furthermore, the microcontroller module, RX485 module, analog signal module, and NB module are all connected to the motherboard pin header.

[0019] Furthermore, the motherboard has pins connected to an analog expansion interface.

[0020] By adopting the above technical solutions, the analog signal channels can be expanded.

[0021] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This utility model ensures that the bottom will not come into direct contact with water or moisture. The moisture-proof pad connected to the inner wall of the waterproof box and the installation of the waterproof gland together constitute an effective waterproof and moisture-proof system, protecting the internal electronic equipment from damage by the external environment.
