Public farmland irrigation DDSY1352-RF machine well irrigation irrigation can use electric meters

Description :

　　Background Introduction

　　On January 21, 2016, the General Office of the State Council issued the "Opinions on Promoting Comprehensive Reform of Agricultural Water Prices" (Guobanfa [2016] No. 2), requiring the establishment and improvement of a mechanism for the formation of agricultural water prices; The overall price of agricultural water has reached the level of operation and maintenance costs, the total amount of agricultural water control and quota management are widely implemented, sustainable subsidy and water-saving incentive mechanisms are basically established, advanced and applicable agricultural water-saving technology measures are widely applied, and the agricultural planting structure is optimized and adjusted.

　　The plan aims to enhance farmers' enthusiasm for water conservation and ultimately achieve total agricultural water use control through methods such as water rights allocation to households, water and electricity metering and charging, water subsidies, water-saving rewards, and water rights trading.

　　Option 1: Local solution centered around prepaid electricity meters for farmland irrigation

　　Applicable scenariosThere is no need to monitor water usage, and billing methods include electricity metering, timing, or converting electricity into water.

　　Prepaid electricity meter for farmland irrigationThe DTSY1352 three-phase prepaid energy meter is used to measure three-phase AC active energy with a rated frequency of 50Hz. It has functions such as prepaid control, load control, time control, and RS485 communication, and its performance indicators comply with the GB/T17215.321-2008 standard. Here are its main functional features:

　　Equipped with RF function, use non-contact RF card to purchase electricity;

　　Swipe the card to get electricity, swipe the card again to cut off the power and retrieve the remaining amount/time;

　　Support purchasing electricity based on electricity price and time;

　　Equipped with alarm function, when the remaining power is insufficient, the backlight of the electricity meter will be constantly on to remind users to purchase electricity;

　　Equipped with scientific control functions, such as automatic power-off function for overload and power-off function for single irrigation time.

　　When the balance is 0, the electricity meter automatically trips and loses power;

　　The balance that exceeds the set usage time will be automatically deposited into the electricity meter, and you can swipe your card to retrieve your balance at any time;

　　Support one meter with multiple cards and one card with multiple meters;

　　The card can record nearly 10 electricity usage records after this recharge, which can be cleared after recharging again.

　　Main functions of the software：

　　1. Main interface

　　The main functions are displayed: opening a new card account, writing cards for purchasing electricity, checking electricity sales, and reading cards.

　　2. New card account opening function interface

　　This interface contains the information that customers need to fill in for opening a new card account, mainly including basic customer information, filling in electricity card information, selecting electricity purchase settlement methods and entering irrigation time, filling in electricity prices and amounts.

　　3. Electricity sales information query interface

　　This interface mainly displays all the electricity purchase records of the current month by default, and can also query the electricity purchase records through conditions. It supports Excel export function.

　　Scheme 2: Water and electricity integrated control cabinet scheme with water and electricity integrated controller as the core

　　Applicable scenariosFor areas with high requirements for water conservation, customers who need to remotely monitor the water and electricity consumption status, and for areas with urgent water consumption control and water conservation subsidies.

　　Integrated water and electricity control cabinetThe intelligent irrigation control box mainly consists of a metal protection box, an intelligent well irrigation controller, a circuit breaker, an electric meter, an AC contactor, a motor protector, a lightning arrester, and other parts. It is installed vertically and suitable for use in the field. The material and size of the metal protective box can be customized according to customer requirements. It can be used standalone or connected to cloud platforms. The main functional features are as follows:

　　Multiple measurement methods: water metering, electricity metering, dual metering of water and electricity, and converting electricity into water.

　　Remote monitoring function: The controller can collect information on the total water output, total electricity consumption, annual water intake, instantaneous flow rate, water level, pump operation status, power supply status, control box door switch status, and user water usage of the well. It can also expand the monitoring of the three-phase current, three-phase voltage, soil moisture, soil temperature and other information of the water pump, and upload these information in real time to the upper management software.

　　Multi card function of one machine: One controller can be used by multiple water users to swipe their cards alternately.

　　Permission control: It can be set that IC cards from different areas (villages, groups) cannot be used interchangeably, and user cards from the same area can only be used within the same area. It is possible to accurately set the user card for each controller.

　　Remote start stop: The water pump can be remotely started and stopped by operating the controller through management software or APP.

　　Swipe card active reporting: When a water user swipes their card to turn on or off the pump, the controller automatically reports the user's irrigation information.

　　Fault alarm and alarm handling: Proactively report when the electricity meter or remote water meter or flow meter malfunctions, and report when the control box door is illegally opened, with voice alarm prompts.

　　Annual water withdrawal over limit alarm function: When the annual water withdrawal of the well exceeds the set upper limit of the annual water withdrawal alarm, the controller actively reports the alarm information to the upper management software.

　　Automatic pump stop function in case of excess: when the annual water intake of the pumping well exceeds the set annual mining output, the controller automatically controls the pump stop, the LCD screen prompts "pump stop in case of excess annual water intake", and the controller actively reports the information of excess mining output to.

　　Insufficient balance alarm in the card: When agricultural water users swipe their cards to collect water, if the remaining amount is less than the set alarm lower limit, the controller will automatically issue a voice alarm to prompt the user that the balance in the card is insufficient and to recharge in a timely manner.

　　Power outage data not lost: If the user suddenly loses power during use, the data in the controller will not be lost, and the user can continue to use it after receiving a call.

　　Perfect electromagnetic compatibility design: Perfect electromagnetic compatibility design and power circuit design, with strong electromagnetic compatibility and power supply working range, suitable for sites without neutral wires.

　　Lightning protection function: With lightning protection function, it can ensure safe operation during thunderstorm season.

　　Motor protection: It has phase loss protection and overload protection functions. When one of the three phases loses phase, it will automatically trip and cut off power; When the electrical load exceeds the allowable power, it will automatically trip and cut off power.

　　Equipment self inspection and fault diagnosis: It has equipment self inspection and remote fault diagnosis functions, including monitoring and measuring equipment, control equipment, communication modules, power supply equipment, etc. It automatically monitors faults when equipment malfunctions, has self-locking function for faulty equipment that affects safety, and promptly reports to the police.

　　Note: The cloud platform is currently under development, and related functions need to wait for the platform to be launched and update the program to be available.
