Problems solved by technology

Different water pumps, different motors, load changes, no-load current and many other factors directly affect the conversion coefficient between electricity and water flow, so it is unreasonable to control water supply with electricity conversion
Another type of product can realize real water measurement, and its measurement methods are all carried out through water meters or flow meters, and the minimum measurement unit is generally 1m 3 , the accuracy is not high

Embodiment Construction

[0039] The automatic charging and automatic control system for the water supply of the motorized well includes an automatic charging management machine for the water supply and an automatic controller for the automatic metering of the water supply for the motorized well. The data transmission between the two is carried out through the medium of IC card. An automatic water supply metering controller for a motorized well includes a metering controller 5, a flow sensor 6 and a distribution box 7 for a motorized well. The flow sensor 6 is installed on the water delivery pipeline 8 .

[0040] The automatic metering and automatic controller system for pumped well water supply uses MCS-51 single-chip microcomputer as the control core, and uses the stored data in the IC card as the basis for automatic water supply control. The display is a commonly used LED digital tube, controlled by a programmable keyboard / display control chip 8279, 138 as a decoder, and the drivers for segments an...

Abstract

The automatic charging control system for water supply of motor pumped well includes one automatic water charge managing subsystem and one automatic metering and controlling subsystem with IC card for data transmission in between. The automatic water charge managing subsystem completes the user card writing and information management, and the automatic metering and controlling subsystem includes metering controller, flow rate sensor and power distributor for the motor pumped well. The flow rate sensor measuring the flow rate and feeds the obtained information to the metering controller. The present invention has friendly man-machine interaction interface, high control performance, high metering precision, automatic power failure protection, and other advantages.

Description

(1) Technical field [0001] The invention relates to an automatic water charge management system, in particular to an automatic charge automatic control system for single or multi-household water use in motor-driven wells. (2) Background technology [0002] In order to promote high and stable agricultural production, many areas are vigorously promoting motorized well irrigation. The metering method of irrigation water for motor-driven wells is scattered in a wide area. At present, water meters are mainly used for metering, and the metering accuracy is very poor. Although China has begun to use automatic control of the metering of pumped well water, in terms of signal acquisition, there are currently two types of products in China. One is a simple water sales controller, which is controlled by indirectly converting the electricity of the electric meter into water volume. Different water pumps, different motors, load changes, no-load current and many other factors directly af...
