Non-contact riverway radar monitoring method, system and device and application

Abstract

The invention belongs to the technical field of computer, embedded, communication and radar detection, and discloses a non-contact riverway radar monitoring method, system, device and application, andthe method comprises the steps: obtaining the distance information of a target through a method of comparing the difference between the frequency of an echo signal at any moment and the frequency ofa transmitting signal at the moment by a continuous wave radar, wherein the distance is proportional to the frequency difference of the echo signal at any moment and the transmitting signal at the moment, and the radial speed and the distance of the target can be obtained by processing the measured frequency difference to detect the position speed information of moving targets on two sides of theriver. The radar detection technology, the detection and communication integrated technology, the space positioning technology and the like are comprehensively utilized; and radar detection and communication technologies are combined to form the novel external field monitoring equipment integrating communication and detection, and security monitoring can be carried out on a monitored river channelin an all-weather mode. Detection and communication are integrated, information is transmitted to a monitoring center through radar nodes in sequence, an illegal sailing ship and a sand dredger are warned, and real-time data storage is conducted on the detected target data.

Description

technical field [0001] The invention belongs to the technical fields of computer, embedded, communication and radar detection, and in particular relates to a non-contact river channel radar monitoring method, system, device and application. Background technique [0002] At present, water resources play a vital role in human life and production, and river management is an indispensable and important link in urban ecological governance, which is closely related to the life and work of residents. In recent years, with the development of industrialization, illegal sand mining in rivers and garbage discharge by some unscrupulous people in reservoirs have brought a great crisis to human water use. Technology is rarely used in the process of river management, and most of the river monitoring is done manually, which will lead to a huge workload, and the monitoring time period is long and the efficiency is low. With the development of science and technology, some departments apply c...

AI Technical Summary

Problems solved by technology

[0005] 1 Due to the long shoreline of the river, wide water surface and high mobility of people, it is greatly affected by weather and wind and waves, especially when it encounters sand, dust, rain and snow, which brings severe challenges to the monitoring system

[0006] 2 There may be false alarms in monitoring

[0007] 3 The detection background noise is large, making it difficult to distinguish the target

[0008] 4 The detection range is narrow and the viewing angle is narrow
