Meteorological monitoring system

Abstract

The invention discloses a meteorological monitoring system, and relates to the technical field of meteorological monitoring equipment. The meteorological monitoring system comprises a data acquirer for acquiring various types of detectors, wherein the data acquirer transmits signals acquired by the detectors to a command central station through communication equipment; the data acquirer adopts two power supply modes, namely an alternating current power supply mode and a storage battery intelligent power supply mode; and the data acquirer is connected with a rainfall and snowfall detector, a visibility detector, a temperature and humidity detector, a wind direction and wind speed detector and an infrared remote sensing pavement temperature measurer through RS485 interfaces respectively and can perform data acquisition and analysis on sand and fog on a high-speed road, the visibility parameter, the pavement temperature, the wind direction, the wind speed, the rainfall factors and the snowfall factors and transmit analysis results to the command central station, so that a site actual situation can be monitored in real time. The meteorological monitoring system can detect all items and detect the sand and the fog on the high-speed road, the visibility parameter, the pavement temperature, the wind direction, the wind speed, the rainfall factors and the snowfall factors in real time.

Description

technical field [0001] The invention relates to the technical field of meteorological monitoring equipment, in particular to a meteorological monitoring system suitable for expressway management systems, capable of providing the most accurate and reliable meteorological data of the highway traffic environment for the highway traffic department, thereby guiding the traffic department to make corresponding decisions. [0002] Background technique [0003] Severe weather phenomena will affect the safety of highway driving and easily lead to traffic accidents. For example, heavy fog and precipitation will reduce visibility, rainy and snowy weather will make the road slippery, strong crosswinds will affect the driving stability of the vehicle, and icy and frosty roads will significantly reduce the friction coefficient of the road surface. It is easy to cause tire blowout and fatigue driving. These weather phenomena will directly or indirectly bring hidden dangers to traffic ...

[0003] Severe weather will affect the safety of driving on the expressway and easily lead to traffic accidents

For example, heavy fog and precipitation will reduce visibility, rainy and snowy weather will make the road slippery, strong crosswinds will affect the driving stability of the vehicle, icing and frost on the road will cause the friction coefficient of the road to decrease significantly, and long-distance high-speed driving in high temperature weather is extremely difficult. It is easy to cause tire blowout and fatigue driving. These weather phenomena will directly or indirectly bring hidden dangers to traffic safety.

In our country, some road meteorological stations are installed according to the design requirements during the construction phase of the expressway. Most of these weather stations are set at a relatively long distance, with an average of 50-80 kilometers to set up a set. It is impossible to know the road and road surface conditions in local or key areas in time. Due to changes in the situation, it is impossible to monitor, warn and evaluate the key local road conditions, and it is impossible to timely and accurately release early warning information on expressway road conditions.

At present, most of the weather stations used in highways are imported products, the price is high, and it is difficult to intensively set up due to the influence of construction funds. Moreover, a single weather station is large in size and has a large number of sensors. For the detection of a certain meteorological element, a dedicated one needs to be set up separately. Sensors, for the detection of road conditions, sensors need to be buried under the road surface, and the construction and maintenance costs are relatively high
