Description

Technical Field

[0003] However, when it is in use, it lacks an effective sealing structure and dehumidification structure, which will bring multiple disadvantages. First, the poor waterproof sealing performance makes the system susceptible to seawater and moisture erosion, causing equipment damage and failure. Secondly, the humid environment will accelerate the corrosion of electronic components and connecting parts, shorten the service life, and increase maintenance costs. At the same time, moisture accumulation may cause unstable signal transmission and affect call quality, especially in bad weather. Finally, the decline in communication quality will also affect the collaboration of operators and increase the risk of accidents. Summary of the invention
