Water and sediment remote monitoring system and method based on dual-link communication

Abstract

The invention discloses a water and sand remote monitoring system and method based on double-link communication. The water and sand remote monitoring system comprises a far end monitoring subsystem used for collecting water regimen data, audio data and video data of a river drainage basin. The water regimen data are sent to a near end demonstration subsystem through a satellite communication link, and the water regiment data, the audio data and the video data are sent to the near end demonstration subsystem through a primary communication link. The near end demonstration subsystem detects the working state of the primary communication link according to the water regiment data received by the satellite communication link, the data collected by the satellite communication link or the primary communication link are selected to serve as calculation data according to a detection result, and demonstration is performed on a graphical interface of a computer.

Description

technical field [0001] The invention relates to the field of river channel monitoring, in particular to a system and method for remote monitoring of water and sand based on dual-link communication. Background technique [0002] Water and sediment transport monitoring has always been highly valued in my country. It is an important basis for the construction of water conservancy projects and the study of reservoir dispatching methods, as well as the basic support for flood control and disaster relief. At present, most of the monitoring of water and sediment transport in China still adopts on-site manual monitoring, and only some areas have adopted more advanced automatic monitoring systems. [0003] The existing automatic monitoring system mainly uses cables or GSM / GPRS to upload data, which cannot meet the needs of users for large data and rich types. Moreover, since most of the monitoring points are set in areas with harsh environments, the degradation of monitoring link pe...

Problems solved by technology

[0003] The existing automatic monitoring system mainly uses cables or GSM / GPRS to upload data, which cannot meet the needs of users for large data and rich types

Moreover, since most of the monitoring points are set in areas with harsh environments, the degradation of monitoring link performance under the influence of bad weather may easily cause false alarms, resulting in distortion of water and sediment monitoring data

Once an emergency occurs, the data transmission link is interrupted, resulting in the paralysis of the automatic monitoring system, which cannot meet the requirements of flood control emergency
