Problems solved by technology

[0004] (1) The function is single, and the existing equipment can only perform one of the three functions of measurement, control and management, which cannot satisfy the three functions at the same time;
[0005] (2) The measurement data is inaccurate. The measuring instrument is installed in the channel. If there is no water or insufficient water in the channel, the measurement data is inaccurate and manual measurement is required, which increases the workload and labor costs;
[0006] (3) The cost of construction is high. It is necessary to install a dozen or more sensors to control each device. The cost of civil engineering is also high. It is necessary to build a large pumping station to operate the entire irrigation area, and it is necessary to fill the entire canal system with water. ;
[0007] (4) The irrigation process is cumbersome, and the usual irrigation method is to operate in the pump station, so the pump station must be established in advance to carry out subsequent irrigation operations;
[0008] (5) In areas with complex geographical environment, it takes a long time to install the whole set of equipment for irrigation in the irrigation area, and the construction cannot be carried out when the temperature is low, resulting in extended construction period, untimely irrigation in the irrigation area, and losses.

Abstract

The invention discloses a measurement and control pipe integrated irrigation area metering device. The measurement and control pipe integrated irrigation area metering device comprises a first irrigation channel and a second irrigation channel positioned at the downstream of the first irrigation channel, wherein the first irrigation channel communicates with the second irrigation channel through aconnection pipeline; the connection pipeline is internally provided with a pipeline flow meter and a gate; soil receiving soil irrigated by the second irrigation channel is internally provided with asoil moisture content sensor for sensing a water demand amount; and the gate is electrically connected with the soil moisture content sensor through a remote control device. The invention further discloses a method for metering by adopting the metering device. The metering device disclosed by the invention is low in construction cost and simple and easy to mount and can be operated and controlledin a full-automatic manner, and measurement and control pipe integrated control is realized.

Description

technical field [0001] The invention relates to the technical field of farmland irrigation, and more specifically relates to a metering device and a metering method for an irrigation area integrating measurement, control and management. Background technique [0002] Irrigation channels are water channels that connect irrigation water sources and irrigated land. They transport and distribute water drawn from water sources to various parts of the irrigation area. Within an irrigation area, irrigation channels are divided into main canals, branch canals, bucket canals, farm canals, etc. according to the size of the control area. There are five levels of canals and canals. In irrigation areas with complex terrain and large areas, multi-level canals such as main trunks, sub-trunks, branches, and sub-buckets can also be added. [0003] In order to achieve the purposes of irrigation, drainage, water supply, shipping and power generation, it is usually necessary to build a series of...
