The observation data of each meteorological element are sent to a data center of a meteorological department in a wireless transmission mode, so that live data and alarm prompt information cannot be displayed rapidly along a highway, and particularly, when high-influence weather conditions such as fog, local strong wind, strong precipitation, road icing and the like occur, the method is not beneficial to timely displaying meteorological monitoring data and live alarm information in situ.
The following problems also exist with conventional six-element automatic weather stations used along road traffic lines.
(1) The bucket of the tipping bucket type rain gauge frequently occurs due to blockage caused by fallen leaves, dust and artificial pollutants, and the reed switch electromagnetic trigger is easy to damage due to long-time mechanical movement.
(2) Because the wind speed and wind direction sensor is arranged at the top of the pull rope type wind rod, the wind rod lodging operation can be completed by multiple persons operating simultaneously during metering checking or maintenance, and the working amount is large. In addition, because the pull rope is exposed in the field for a long time, the pull rope is corroded seriously, so that the pull rope is easy to break suddenly, and potential safety hazards exist.
(3) The surrounding environment of the special observation site is easily influenced by external factors, such as temporary buildings, temporary overhead cables, excavated water surfaces, tree branches and leaves and damages caused by human invasion, the detection environment is seriously interfered, and the daily maintenance of the special site is difficult.
