"UAV has a wider coverage and higher efficiency, which can directly and clearly reflect whether there is garbage in the river, whether the river is black and whether the flow is smooth." Liang Xiaoqi said that they will sort out and classify the real-time information of river environment collected on site, compare and analyze the monitoring data with the newly established remote control system of "smart water" in Shugang - Slender West Lake scenic area, and conduct comprehensive research and treatment.

"Located in the main urban area, it is also a scenic spot. It is not allowed to be careless about the water environment." Zhou Hao said that in order to accurately and timely manage and protect a city's clear water, the scenic area has built a "smart water" management system and introduced a new mode of UAV River patrol. The scene picture of the river is transmitted to the background management system in real time through 360 ° camera, and synchronized to the mobile app. The river directors at all levels of the scenic spot turn on their mobile phones, and the river situation is clear at a glance. At the same time, the scenic spot also establishes the UAV patrol information report, classifies and combs the UAV patrol video and pictures, transforms them into data and text materials, reports once a week, the river management responsibility is clear, and the problems are solved.

 

"The riverway of the scenic spot is like a face of the city. If the management and protection is not good, it will lose face. The application of modern technology can greatly improve the efficiency of management and protection." Zhou Hao said that the traditional river patrol is time-consuming, labor-intensive and inefficient. In order to protect the green water of a city, the scenic spot is based on the remote control management platform of Tangzi city moat, and the project of Beicheng river is promoted to improve the phase II "intelligent water" remote control management platform with Tangzi city moat as the center and covering Beicheng River, Guanhe River and Haotian river. At the same time, it is equipped with modern technical equipment such as air UAV monitoring, water surface full-automatic water grass harvester, forming a three-dimensional supervision system.

"This system can not only monitor the river course and hydraulic structures in the scenic spot in real time, ensure the 24-hour real-time monitoring of water conditions, and meet the requirements of" no man on duty, few people on duty ", but also can carry out remote centralized automatic control of electrical equipment such as sluice, pump group in the system, so as to achieve the new level of precise water source scheduling." Zhou Hao said that modern water science and technology is a powerful weapon to win the "two wars". The scenic spot has entered the normalization mode by using UAV to patrol the river, taking panoramic aerial photos of all rivers every month, understanding the current situation and pollution degree of the river through front and back comparison, and testing the water control effect. The fully automatic water and grass harvester put into use cleans more than 15 harmful aquatic plants every day during the high incidence period of water and grass. T, to maintain the ecological balance of the river to prevent the outbreak of cyanobacteria.

 

According to the reporter, the establishment of three-dimensional management and protection of "smart water" is only the first step for the scenic area to explore river management and protection. In the later stage, UAV technology and functions will also be studied. Through aerial mapping and patrol inspection, data will be obtained and models will be reconstructed, digital monitoring data will be provided for the river, and "one picture of big river and small ditch" will be realized to supervise the blind area, so as to achieve a more efficient, scientific and modern River management mode.
