On September 10, a drone hovered low in tangzicheng moat wetland. At the scene, Liang Xiaoqi, a river inspector in the hechangban UAV of Shugang - Slender West Lake scenic spot, constantly controls the remote control in his hand, and the real-time situation of vegetation and water on both sides of the river is clearly displayed on the display screen.

 

There are two "eyes" in the air staring at the river

 

"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.

 

"We will organize manpower and machinery in time to deal with the problems such as floating objects on the water surface, planting on the bank slope, dumping garbage and so on, so as to solve the environmental hazards in time." Zhou Hao, the commander on duty on that day and the head of the water management center station of the scenic spot, said that there are only 15 district level rivers in the scenic spot, which seems to be a small number, but the river structure is complex and the vegetation is rich, so if you don't pay attention to it, there will be garbage floats.

 

"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.

 

"One picture of big river and small ditch" to realize no blind area of supervision

 

"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.

 

Manage and protect water environment to create a scenic spot

 

With automation equipment, does it mean that there is no need for human investment? Of course not. According to the introduction, since the issuance of order No. 1 of Yangzhou City General River manager, river managers at all levels in the scenic spot have consciously fulfilled their responsibilities, took the lead in carrying out river patrol in flood season and safety inspection of water conservancy projects under construction, focused on the implementation of key tasks, focused on the implementation of level one and level by level, and carried out in-depth special investigation and remediation of "two violations and three chaos" in sewage outfalls and rivers and lakes. For the problems found in the patrol inspection and reported by the masses, we should implement the principle of "one task, one task", form a list handed over by the river chief, timely hand over and investigate, and ensure that everything is settled and everything is echoed.
