Tunnel meteorological station

1、 Introduction to Tunnel Meteorological Station Products

Highway meteorological station is an integrated application of various meteorological sensors from structure to system composition using comprehensive collection and control technology, computer software technology, communication technology, and other technologies. Capable of continuously obtaining meteorological information along transportation routes and improving visibility; Wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall; Real time monitoring of meteorological elements such as road conditions is carried out, and various data are summarized and transmitted to the door in a timely manner through remote transmission, providing hand data for transportation related departments to provide timely meteorological support services along the route. Based on this, timely meteorological information services can be provided for highway safety authorities and people's travel.

The composition of the highway meteorological station system includes meteorological sensors, collectors, pole supports, power supply system, and cloud platform
