Measurement and control integrated device for irrigation district canal system water metering and control method

Abstract

The invention discloses a measurement and control integrated device for irrigation district canal system water metering and a control method. The device comprises a gate, a water level sensor, a flowsensor, an opening sensor, a remote terminal controller, a communication module and a motor are installed on the gate, an output end of the remote terminal controller is connected with an input end ofthe motor, and the remote terminal controller is connected with the water level sensor, the flow sensor, the opening sensor and the communication module separately. According to the device, the structure is simple, convenience is brought to construction, the metering precision is high, the stability is high, irrigation district canal system water can be metered through the water level sensor, theopening sensor and the flow sensor, not only can the cross section of a canal system be measured, but also the measuring error brought by cross section changes of a natural canal can be avoided; flowcontrol, information transmission and other functions can be achieved through the communication module. The device can be widely applied to the irrigation district canal systems.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to an integrated measurement and control device and control method for water volume measurement of canal systems in irrigation areas. Background technique [0002] In recent years, with the implementation and implementation of the water resources management system, water intake metering, as an important part of the local total water intake control, has been paid more and more attention. The automation, informatization and intelligent construction of water intake metering has become the primary content and focus of current water resources management. Important starting points, especially the National Water Resources Monitoring Capability Project launched nationwide in 2012, have put forward higher requirements for water intake metering monitoring and informatization construction. According to the purpose of water intake, water intake can be divided into agricultural w...

AI Technical Summary

Problems solved by technology

There are deficiencies in the above methods, which are as follows: ① The water level and flow relationship is unstable, and the changes of the underlying surface of the canal system and the shape of the section of the canal system in the natural state all have a certain impact on the water level and flow relationship; ② Some have sluice control The canal system has tank storage function, and irrigation water is stored in the canal system, so there will be a working condition of water level but no flow, which will cause measurement errors; ③ It is impossible to control the irrigation volume of Maonong Canal in each branch of the irrigation area
