Embodiment Construction

[0021] The present invention is a water and electricity joint control type prepaid IC card machine well water intake control system, which includes an IC card and a prepaid IC card machine well water intake control device. The IC card machine well water intake control device reads the amount and unit price information in the IC card, starts the water pump motor to start water supply, and the system automatically transfers from the IC card according to the user's water consumption, electricity consumption and the set unit price of water and electricity during the water intake process. The corresponding amount is deducted from the card. When the remaining amount in the IC card is less than the minimum consumption amount, the motor can be automatically turned off to stop water intake.

[0022] Specific steps are as follows:

[0023] 1. The user inserts the recharged user IC card into the prepaid IC card machine well water intake control device;

[0024] 2. The user starts the co...

Abstract

The present invention belongs to the field of control technology, and solves the technological problem of water fetching control system including metering the water amount and power consumption of motor pumping well and pre-paying with IC card. The control process includes the following steps: inserting the IC card; starting the controller via the user operation interface circuit; the controller reading the information in the card and starting water pump; the controller deducting the water consumption and power consumption money; shutting off the motor of the water pump to finishing water fetching; and the controller writing the residual money into the IC card. The water fetching control system includes water pump, power meter, microprocessor, water amount collecting circuit, IC card interface circuit, electric power metering sample circuit and water pump driving control circuit.

Description

technical field [0001] The invention relates to an automatic control device for water quantity metering and electricity metering for pumped well water intake, and belongs to the field of control technology. Background technique [0002] With the growth of population and the development of industry and agriculture, the collection of groundwater is increasing, and the precious groundwater resources are becoming increasingly scarce. In terms of water resources utilization, due to the lack of people's concept of water saving and the outdated and backward water intake facilities, the utilization rate of agricultural irrigation water and water used by enterprises and institutions in our country is low. At the same time, the traditional irrigation method does not have the concept of quantity for irrigation water intake, but uses the irrigated area or water intake and electricity consumption as the basis for metering and billing. The method is very unreasonable and has caused a grea...
