With the rapid development of my country's economy and urbanization, and the rapid improvement of living standards, the country and society have begun to pay more and more attention to the protection of the surrounding environment. For a long time, there has been a lack of effective supervision methods for the supervision and management of environmental pollution and environmental protection law enforcement. Excessive discharge and illegal discharge have occurred from time to time, and the task of environmental supervision is heavy and difficult.
　　The traditional fixed-point environmental monitoring method has certain limitations and one-sidedness, and cannot be used for overall environmental monitoring. In the process of environmental monitoring, emergency response, and supervision and law enforcement, it is often restricted by unfavorable factors such as terrain, environment, and traffic. CAMERA's pollution source online monitoring visualization system realizes real-time, accurate and comprehensive information collection of pollution sources through a multi-directional front-end layout, and builds an all-weather, three-dimensional, multi-level intelligent environmental protection perception system, making the perception monitoring more thorough and resource integration More comprehensive, more in-depth smart applications.
　　1) Finding the source of pollution: using the mobility of drones and the high-altitude observation capabilities of PTZ cameras to detect pollution in time and locate the source of pollution;
　　2) Obtain the image data of the pollution source: the collected images and the monitoring data are mutually verified to ensure the reliability of the monitoring data;
　　3) Data and image overlay display: realize the overlay display of image and monitoring data in the monitoring center, making supervision more convenient and intuitive;
　　4) All-round monitoring of pollution sources: UAVs are used to monitor small workshops and other scattered pollution sources, so as to obtain sewage image data in multiple directions and dimensions.
　　The pollution source online monitoring visualization system is a large-scale networked monitoring system integrating hardware, software, and network. With the iVMS-9800 platform software as the core, it realizes multi-level networking and cross-regional monitoring. The front-end system can be centralized and unified in the monitoring center. management.
　　Drone---over distance monitoring
　　The aerial patrol adopts Hikvision's high-performance Eagle series drones, which have a wide field of view and can be moved flexibly. With the help of a three-axis pan-tilt camera, it supports 30x optical zoom, 12x digital zoom, and monitors the sewage discharge status of the sewage outlet from a distance to improve The ability to detect the act of sneaking and draining;
　　UAV---Ultra stable image acquisition
　　The drone has a gimbal self-stabilization system and an independent attitude measurement sensor, which ensures that the drone takes stable on-site images during the flight;
　　Same platform management
　　Environmental image data collected in three dimensions can be connected to the same management platform, which is conducive to building a three-dimensional, multi-level image database;
　　PTZ camera --- super long-distance high-altitude observation
　　The high-magnification pan/tilt camera is set up in the higher part of the town. It monitors the urban environment in a way of "standing high and looking far away", which not only takes into account the big scene, but also achieves close-up shooting of specific targets, which can meet the requirements from 1KM to 5KM. The monitoring needs of cities and towns will help the environmental protection department find the source of pollution early;
　　Fixed-point monitoring---multi-dimensional data collection
　　The fixed-point monitoring adopts starlight-level high-definition cameras or thermal imaging cameras to meet the requirements of real-time monitoring of important parts such as sewage outlets and production processes of national, provincial and municipal pollution sources under low illumination conditions, and from ordinary light and heat. Multi-dimensional analysis of pollution and data.
