Steel plant sewage discharge monitoring method and system based on unmanned aerial vehicle

Abstract

The invention discloses a steel plant sewage discharge monitoring method and a steel plant sewage discharge monitoring system based on an unmanned aerial vehicle. The steel plant sewage discharge monitoring method and the steel plant sewage discharge monitoring system can operate for 24 hours in all kinds of weather and are high in measurement precision. The steel plant sewage discharge monitoringmethod comprises the following steps of: (10) patrol inspection of a specified water region, specifically, flying according to a planned route, collecting millimeter wave radiation data and positioninformation of the water region along the way, monitoring an abnormal signal, and determining suspicious pollution discharge water regioninformation; (20) detailed inspection of the suspicious water region, specifically, determining whether the suspicious water region is a pollution discharge point or not according to radiation data, position information and an optical image of the suspicious water region; (30) detailed inspection of a pollution discharge point, specifically, performing cone scanning on the pollution discharge point, and acquiring a radiation image of the pollution discharge point by using a passive millimeter wave imaging system; (40) and comprehensive judgment and early warning, specifically, judging a pollution level of the pollution discharge point, generating different early warning information and sending the information to an environmental protection department. The steel plant sewage discharge monitoring system comprises an unmanned aerial vehicle monitoring end (1) and a ground control end (2).

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and is an all-day, all-weather, high-precision drone-based sewage discharge monitoring method and system for iron and steel plants. Background technique [0002] With the continuous development of industry, the problem of industrial sewage discharge has become more and more serious. Although various policies and laws have been introduced in recent years to put sewage prevention and control on the agenda, many unscrupulous manufacturers still use various methods to secretly discharge sewage. Among them, the iron and steel industry, as an industry with high energy consumption, high water consumption and high pollution, is a major player in energy, resource consumption and pollutant discharge. Wastewater in the iron and steel industry mainly comes from production process water, equipment and product cooling water, flue gas washing and site flushing, etc. 70% of the wastewater comes ...
