Abstract

The invention relates to a Doppler gate flow measurement method and device, and belongs to the technical field of water conservancy gate flow measurement and data remote transmission. According to the technical scheme, the device comprises a gateway (1), a flashboard (2), a gate flow measurement device, a Doppler flow speed sensor (4) and a gate level sensor (5). The flashboard is vertically arranged on the gateway, the gateway is connected with a flashboard opening / closing machine, and the flashboard opening / closing machine controls the flashboard to be opened or closed on the gateway. The gate level sensor is arranged on the flashboard or the flashboard on-off machine in a matched mode, the Doppler flow speed sensor is arranged in the middle of the bottom of the portion, behind the flashboard, of the gateway in a matched mode, the Doppler flow speed sensor and the gate level sensor are provided with intelligent instruments respectively in a matched mode, and the gate flow measurement device is connected with the intelligent instrument of the Doppler flow speed sensor and the intelligent instrument of the gate level sensor in a wired or wireless mode. By means of the Doppler gate flow measurement method and device, the gate flow is worked out precisely through a flow rate area method for the first time, continuous online measurement is achieved, high-precision computation of the gate flow is achieved, and management of management departments is convenient.

Description

technical field [0001] The invention relates to a Doppler gate flow measurement method and device, belonging to the technical field of water conservancy gate flow measurement and data remote transmission. Background technique [0002] At present, the calculation formulas used in the existing water conservancy sluice flow measurement methods generally have an error of more than 15%. The above-mentioned defects have plagued industry personnel for a long time, but there has been no better solution for many years, which limits the application of gate water measurement to a certain extent. Contents of the invention [0003] The object of the present invention is to provide a method and device for measuring flow through a Doppler gate, which can calculate the flow through the gate with high precision by using the flow velocity through the gate, and solve the above-mentioned problems in the background technology. [0004] Technical scheme of the present invention is: [0005] A...
