Problems solved by technology

However, the existing measuring instruments have the following problems: 1. The function of the secondary instrument is limited to counting the accumulated water volume, and the instantaneous water level, flow and other data cannot be stored and exported on site; Unstable; 3. The power supply is mainly AC220 volts, which is difficult to guarantee, especially for remote areas, which is not suitable for widespread use in irrigation areas

Embodiment 1

[0037] Embodiment 1, the channel section to be monitored is laid as a square, such as Figure 4 , through the upper computer to fit the shape of the laid channel, configure it with the intelligent water level detector, set the liquid level transmitter as a single-channel input static pressure liquid level transmitter, when in use, it can be installed in the intelligent water level detector Data information such as channel water depth, flow, water volume, date, etc. can be read in real time on the LCD screen.

Embodiment 2

[0038] Embodiment 2, the channel section to be monitored is laid as a trapezoid, such as Figure 5 , Fit the shape of the laid channel through the upper computer, configure it with the intelligent water level detector, and set the liquid level transmitter as a single-channel input static pressure liquid level transmitter. When in use, data information such as channel water depth, flow, water volume, and date can be read in real time on the LCD screen of the intelligent water level detector.

Embodiment 3

[0039] Embodiment 3, lay a spring hole between channel upstream and downstream, as Figure 6 , the parameters are fitted by the host computer according to the shape of the channel, and the data is remotely input by GPRS to the intelligent water level detector for configuration, and the liquid level transmitter is set as a two-way input static pressure liquid level transmitter. When in use, data information such as upstream and downstream parameters, flow, and water volume of the channel can be read in real time on the LCD screen of the intelligent water level detector.

[0040] The present invention has many advantages such as flexibility and convenience, strong adaptability, accurate measurement, all-weather measurement, practicality and reliability, and convenient installation. Provides accurate real-time data on water use.

Abstract

The invention discloses an intelligent water measurement system used in canals and river channels. The system is flexible and convenient to operate, high in adaptability, accurate in measurement, capable of achieving daytime measurement, practical, reliable and convenient to install. Power is supplied according to the scheme that a 12 V large-capacity polymer lithium-ion battery and a solar panelare combined to charge, data can be displayed on site and can be copied by using a U disk on site, and a data management mode that remote transmission is conducted through a GPRS module can be adopted. In use, the system can remotely set parameters through a GPRS according different ditches, the number of sensors is flexibly set, the system is suitable for on-site or remote real-time measurement of water level, flow and water quantity of various farm irrigation canals or river channels, and the accurate real-time data is provided for agricultural irrigation water.

Description

technical field [0001] The invention belongs to the technical field of automatic detection and relates to an intelligent real-time water level, flow and water volume measurement system, in particular to an intelligent water volume measurement system for channels and river courses. Background technique [0002] Open channel flow measurement is an effective measure for saving water, improving irrigation quality and irrigation efficiency in irrigation districts, an important means for accurate water diversion, water delivery, water distribution and irrigation in the process of implementing water use plans, and also the main basis for verifying and calculating water fees. Using a basic water gauge or measuring rope to measure and obtain water level data, the entire measurement process is cumbersome, time-consuming, and laborious, and is easily affected by human factors, resulting in large reading errors, and the inconvenience of night measurement readings leads to even greater er...
