Agricultural electricity based water management system

Agriculture converts electricity into watermanagement system

Water metering mode

In areas where only the measurement of water volume in agricultural irrigation wells is required, a relatively simple "water volume measurement" mode can be adopted, which involves selecting appropriate types of water measurement instruments and construction plans based on the site conditions, installing online water measurement facilities on agricultural irrigation wells, and ensuring data reporting to the provincial platform. When adopting the "water quantity measurement" mode, in principle, the county-level water administrative department should introduce third-party measurement service enterprises (hereinafter referred to as "service enterprises") with relevant service capabilities through public recruitment and signing of long-term service contracts to be responsible for the construction and management of the agricultural irrigation well measurement system within its jurisdiction. Service enterprises should use their own funds to carry out the construction of the measurement facility system, and as the property owner of the measurement facility, be responsible for the operation and maintenance management of the measurement facility during the service period stipulated in the contract. The county-level water administrative department shall, in accordance with the contract agreement, gradually pay the service fee in installments during the contract period based on the quality of measurement data services provided by the service enterprise. The annual service fee payment standard and payment method shall be determined on the basis of comprehensive consideration of factors such as one-time construction investment, annual operation and maintenance costs, equipment depreciation period, reasonable financial costs and profits of the service enterprise.

Technical scheme for controlling underground water resources through electricity conversion

At the measurement and control site, based on specific circumstances, in order to meet measurement requirements and minimize the impact on farmers, pipeline modifications and alterations should be avoided as much as possible. If necessary, modifications should be made by extending the water well vertically upwards without adding bends to meet the measurement requirements of the measuring equipment and achieve accurate measurement. This project is mainly divided into three categories based on the site environment:

Category 1: If the on-site horizontal direction cannot meet the measurement requirements through the extension pipeline, vertical construction is used to meet the equipment measurement requirements. As the equipment is constructed inside the wellbore, pipe section ultrasonic flow meters and water meters are used for underground construction, with separate RTUs,

The second type: those that meet the measurement requirements on site or meet the measurement requirements through simple modifications,

Category 3: There is no fixed pump on site, and online water measurement needs to be carried out through an electric water telemetry terminal

Product Overview

• This product is developed by our company specifically for the management and measurement of water consumption in non pump fields for agricultural irrigation wells. It is an electric water conversion underground water resource control device, and the principle of water measurement is based on electric water conversion calculation. It can accurately calculate water consumption based on the electricity consumption of the well.

• The underground water resource control device for agricultural machinery wells adopts an integrated design, including an electricity collection module, a 4G transmission module, a display module, and a machine well start stop control module.

(1) Electricity collection module: using a digital three-phase energy metering chip to achieve well use····The measurement of electricity is carried out and connected to the core module of electric water through pulse mode, with an accuracy of level 1.

(2) Start stop control module: The start stop control module uses a three-phase magnetic holding relay, which is in a normally engaged state. After exceeding the rated water usage, the load is separated and the power is cut off. Carrying current AC380V/60A, mechanical durability 100000 times, electrical durability 5000 times.

(3) 4G communication module: using 4G communication module or 4Gcat1 module to ensure communicationThe quality and stability of the information.

(4) Chinese character display module: using 19264 Chinese characters for easy viewing of water usage information.

(5) Electric water conversion module: using fixed and variable coefficients to convert electricity consumption into water consumption,And responsible for scheduling and coordinating the other four modules.
