Problems solved by technology
[0003] Although the accuracy of weather forecast is constantly improving, it is often aimed at a large area, for example, in the administrative areas of cities, counties, and townships, the accuracy of weather forecasts will vary.
In some areas with complicated climate conditions, the days may vary from ten to ten miles. Therefore, it is unrealistic to rely on weather forecasts to make early warnings of weather conditions in a small area, especially the hazards of fog.

The invention discloses a fog early warning device and a control evaluating method for roads and airports. The fog early warning device comprises a general controller and multiple collecting terminals. The general controller is installed in a control chamber. The multiple collecting terminals are installed out of the control chamber and comprise a fan, a molecular sieve type revolving wheel, an air condensation liquefier, two weight sensors, a solid particle collector, a temperature sensor and a sub-controller. The sub-controller is connected with the general controller through a network. The fog early warning device and the control evaluating method for roads and airports have the advantages of being dynamic as fog forming conditions can be continuously analyzed around the clock, being accurate as a partial zone is monitored and accurate early warnings can be made when the fog forming conditions approach and intelligent as workers do not have to supervise after the early warning device is in operation, and the system automatically operates and sends out a warning signal based on set conditions.
Description
technical field [0001] The invention belongs to the technical field of road engineering detection facilities, in particular to a fog hazard early warning device for highways and airports and a control evaluation method. Background technique [0002] The safety of aircraft takeoff and landing has a lot to do with the weather conditions around the airport. In recent years, flight safety accidents and flight delays at home and abroad are all related to the weather conditions around the airport. Fog is a common weather factor that induces flight accidents. According to different causes of fog, it can be divided into 9 categories: radiation fog, advection fog, evaporation fog, uphill fog, frontal fog, mixed fog, smog, valley fog and ice fog . The causes of each type of fog are related to the local geographical environment and climate characteristics. Under the joint action of specific temperature, moisture content and solid particle content in the air, the concentration of fog ...
