Description

Water quality mobile detection system Technical Field The invention relates to the technical field of water quality detection, in particular to a water quality mobile detection system.

The system mainly comprises four types of portable field detection, a vehicle-mounted shipborne mobile laboratory, an unmanned intelligent monitoring platform and a miniaturized fixed semi-fixed monitoring station, and is adapted to different scenes by taking suitcases, refitted vehicles, unmanned ships, miniature stations and the like as carriers. The portable equipment is flexible and portable, the detection capability of a mobile laboratory is high, the unmanned platform can move independently, and the miniature monitoring station can form a monitoring network. The technology can be used for scenes such as daily inspection, emergency of sudden pollution and the like by virtue of mobility and real-time advantages, and the technology is developed towards the direction of intellectualization, integration and networking in the future. When the pollution of the river channel at the downstream of the industrial park is traced, due to the intermittence of pollution emission and the dynamic property of hydrologic conditions in the water quality moving detection process, the whole capture of the pollution event overview is difficult through the instantaneous snapshot of single navigation, and the sparsity of the data in the space-time dimension can not convert the authenticity of the data into effective representativeness. When these sparse and possibly lagged data are input into a diffusion model which depends on fixed parameters for deduction, serious cognitive deviation is generated in the model due to incorrect position input and distorted hydrologic conditions, and a distorted 'pollution map' is generated. The direct consequence is that the emergency command department carries out resource deployment according to the error map, such as rail layout and treatment agent addition, completely deviates from the actual position and diffusion path of the pollution group, thereby not only wasting precious emergency resources and missing key treatment occasions, but also possibly causing the continuous downstream diffusion of the pollutants which are not intercepted and forming a substantial long-term threat to the drinking water safety or sensitive ecological system.
