A device and method for real-time detection of dust in a stockyard and intelligent sprinkler dust reduction based on video technology

Abstract

The invention discloses a video technology based real time stockyard airborne dust detection and intelligent watering dust depositing device and method. The device comprises a video monitoring device,a computer, a wind speed and wind direction measuring device, a PLC and a watering device. An optimized neural network or other algorithm is combined with static and dynamic characteristics of airborne dust to process real-time video data of stockyard airborne dust, an initial coordinate of a dust area and an estimated value of the airborne dust concentration are calculated, wind speed and wind direction measurement data is combined to implement calibration, the coordinate of the dust area, namely the coordinate of a watering area, is determined finally, and according to the coordinate of thewatering area and the estimated value of the airborne dust concentration, the PLC controls the watering device to carry out watering dust depositing in a dynamic graded way according to areas Thus, real-time monitoring can be realized in different environmental conditions, a control instruction is timely, and the construction and maintenance cost is low; and dust is inhibited effectively, it is ensured that increase of the water content of materials stored in the stockyard is within a controllable range, and labor, material and transport materials are saved.

Description

technical field [0001] The invention relates to the technical field of intelligent dust reduction, in particular to a device and method for real-time detection of dust in a stockyard based on video technology and intelligent sprinkler dust reduction. Background technique [0002] The stockyard is the main place for stacking bulk materials. Bulk materials include coal, ore, bauxite, etc. Among them, coal transportation is one of the main businesses of port logistics. It will inevitably generate a lot of dust during the process of stacking, storage and transshipment. coal dust pollution. Flying dust not only causes environmental pollution and resource waste, but also affects people's health and industrial production safety. Therefore, water spraying is usually used for dust reduction and dust removal during storage or transportation. At present, the sprinkling and dust removal operations mainly adopt manual control. When the weather changes, the coal type is different, or ob...

Problems solved by technology

[0004] The purpose of the present invention is to provide a real-time detection of dust in the stockyard based on video technology and an intelligent sprinkler and dust reduction device and method, so as to solve the problem of too little watering and poor dust prevention effect in the existing technology of sprinkling and dust reduction, or excessive watering and waste. Hydropower resources and increase the moisture content of stockpiled materials, which affect the technical problems of material quality
