Method for accurately monitoring and analyzing reservoir storage capacity

Abstract

The invention discloses a method for accurately monitoring and analyzing reservoir storage capacity. The method comprises reservoir storage capacity accurate monitoring and reservoir storage capacity accurate analysis. The reservoir storage capacity accurate monitoring comprises the following steps: an intelligent unmanned ship is adopted to measure reservoir sedimentation; designing section lines and corresponding coordinate parameters are input in an unmanned ship system self-contained by the intelligent unmanned ship; the intelligent unmanned ship automatically conducts water-depth measurement according to designing course and set sample intervals strictly, and acquires measuring data and records accurate global position system (GPS) location of the point. The reservoir storage capacity accurate analysis comprises the following steps: a database management platform is established with the measuring data measured termly by the intelligent unmanned ship; the designing section lines and the measured data are stored in a database and are used to analyze the siltation volume in different time and research the siltation speed. According to the method, the intelligent unmanned ship monitors the reservoir storage capacity through establishing the idea of long-time series. The comparison of analyzed results is of great importance to the changing of the reservoir storage capacity and the capacity of predicting flood storage.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitoring, and mainly relates to a method for accurately monitoring and analyzing reservoir capacity. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Water conservancy projects can play a greater role in flood control, farmland services, hydropower generation, ports and navigation, prevention of soil erosion and water pollution, etc. Water conservancy projects, especially reservoirs, are generally large in scale, complex in technology, long in construction period and large in investment, so their monitoring, maintenance and analysis in the later stage are of vital significance. [0003] The calculation of the existing reservoir storage capacity is mainly carried out by manned ships carrying depth sounders to measure the section, and ca...

Problems solved by technology

[0003] The calculation of the existing reservoir storage capacity is mainly carried out by manned ships carrying depth sounders to measure the section, and calculate the storage capacity based on the section measurement data. However, when measuring the section with this method, due to the influence of factors such as water flow and human control, the hull travel will be different from the design section line. Secondly, because the navigation speed is difficult to control, the interval between the acquisition points of the depth sounder will also be unstable, which will affect the measurement effect of the section, and then affect the calculation of storage capacity; in addition, the measurement of different sections in different periods is designed for the analysis of storage capacity There is also the effect of error
