china news service zhejiang news september 4 (zhang yicong wang shanshan) recently, zhejiang jinhua yongkang qianjiang water co., ltd. (hereinafter referred to as qianjiang water) introduced drone leak detection technology and carried out detection experiments with this technology in the company's business company, further confirming the actual role of this technology in the inspection and maintenance of water supply network leakage.

a relevant person in charge of qianjiang water affairs said that this experiment used drones equipped with sar radar to detect abnormal conditions in the water supply network, and the locations were selected in open areas such as shengli street, gushan town and longshan town in the urban area.

specifically, by applying the large-scale full-polarization image data of the regional long-wave synthetic aperture radar, and processing it with filtering and noise reduction techniques, the dielectric constant information is extracted to analyze the soil moisture content, and then the suspected leakage points in the area are interpreted. this experiment found 5 suspected leakage points, which were subsequently manually reviewed and the uav detection experiment was effective.

at present, qianjiang waterworks' network inspection and leak detection are mainly done manually, which still has limitations in accuracy and efficiency. this time, the company innovatively introduced drone network leak detection technology, which helps to efficiently and fully inspect the water supply network and expand the screening scope of suspected leakage areas, saving manpower and greatly improving inspection efficiency.

in recent years, qianjiang water has taken safe and high-quality water supply as its starting point and foothold, deepened the empowerment of scientific and technological innovation, fully integrated the results of intelligent construction into the entire process of production management and social services, and is committed to creating more efficient and convenient water supply services. next, the company will continue to be innovative, actively introduce advanced concepts and technologies, and continuously accelerate the transformation of results to provide more solid and reliable water technology for modernization construction.
