Modulated sound wave generating device for artificial fog dispersal and control method of device

Abstract

The invention discloses a modulated sound wave generating device for artificial fog dispersal and a control method of the device. The device comprises a skid-mounted chassis arranged on a transport vehicle; a power system, a sound wave generating system, a rotating system and an industrial personal computer control system are arranged on the skid-mounted chassis; the skid-mounted chassis comprisesa base, a tray and a hanging ring; the power system comprises a diesel generator and an air supply combination; the sound wave generation system comprises a loudspeaking horn and a sound wave modulation generator; and the rotating system comprises a horizontal rotating mechanism and a pitching hydraulic cylinder. The specific control method comprises the steps of: 1, starting; 2, meteorological information acquisition; 3, sound wave modulation; 4, fog dispersal operation; 5, self-action fog dispersal operation; and 6, shutdown. Compared with the prior art, the device can assist in solving thedefect that an existing low-frequency sound wave fog dispersal device only aims at radiation fog manual operation, cannot objectively evaluate an operation effect, cannot adjust an operation direction and a pitching angle, cannot adjust an operation state according to the meteorological changes of an operation process operation area, and cannot save energy.

Description

technical field [0001] The invention relates to the technical field of artificial weather modification, in particular to a modulated sound wave generating device for artificial fog removal and a control method thereof. Background technique [0002] The sonic defogging device is a kind of equipment for artificially modifying the weather. This equipment is used to eliminate fog damage in local areas such as airports, ports, and expressways in an emergency to ensure the smooth progress of transportation or major events. [0003] The fog can be divided into two types based on whether the temperature is higher than 0°C or not: the fog that appears when the temperature is higher than 0°C is called warm fog; the fog that appears when the temperature is lower than 0°C is called cold fog. Existing artificial defogging technologies such as heating methods for fog in a small area, burning gasoline and other fuels in large quantities, or using aeroengines to spray fire to heat the air, ...
