Embodiment 2

[0070] A measurement method based on an automatic measurement system for river section flow, comprising the following steps:

[0071] Corresponding setting of S1 flow measurement station: enter the name and coordinates of the flow measurement station and the corresponding device number of the flow measurement trolley 1 on the measurement control management platform to realize the corresponding control of the flow measurement station by the measurement control management platform;

[0072] S2 pre-start: first turn on the power of the current measuring car 1, wait for a few seconds, the pre-start is completed; then check whether the equipment is running normally;

[0073] S3 Set flow measurement parameters: According to the basic information parameters of the channel, set the flow measurement mode and the number of measurement points on the measurement control management platform and save them;

[0074] For example, set the number of times of flow measurement per day, set the nu...

Abstract

The invention discloses an automatic measurement system and measurement method for the flow rate of a cross section of a river channel. The automatic measurement system comprises a flow measurement trolley, a measurement bridge, a flow measurement station building and a data center, the measurement bridge is installed on a river channel in a crossing mode, the flow measurement trolley runs along the measurement bridge, and the flow measurement station building is built on one side of the measurement bridge; the flow measurement trolley comprises a remote measurement and control terminal and a data acquisition device; an on-off control device and a PC terminal are arranged in the flow measurement station building, and the data center is in communication connection with the flow measurement trolley, the on-off control device and the PC terminal. According to the invention, the data center is in communication connection with the equipment in the flow measurement station building and the flow measurement trolley, so that flow measurement control, emergency braking control and flow measurement station building door opening and closing control are carried out on the flow measurement trolley through the data center; the remote measurement and control terminal calculates the instantaneous flow and the accumulated flow by using a channel section method according to the set channel section data and a flow calculation formula and transmits the flow data to the data center, manual guarding is not needed in the whole process, and the flow data is more accurate compared with a traditional measurement mode.

Description

technical field [0001] The invention relates to a river flow measurement technology, in particular to an automatic measurement system and a measurement method for a river section flow. Background technique [0002] The main way of guiding and distributing water in irrigation districts in my country is open channel water delivery. The measurement of channel flow in irrigation districts is conducive to saving water. The traditional method of river flow measurement is to use manual operation to control the deployment of rotor flow meters to several designated locations on the river flow measurement section. By synchronizing the measured flow velocity and water level, and then according to the flow velocity area method, the flow test is realized. The whole process needs to be manually guarded, which is time-consuming and labor-intensive. At the same time, the manual operation controls the deployment of the rotor current meter in the river channel, and the accuracy of the water d...
