Meter is analyzed and manages the data syn-chronization of subsystem 1 with agricultural water.
Motor-pumped well water intaking monitor terminal 3 supports that IC-card is swiped the card keying, and the data for water, electricity, water level are adopted in real time
Collection, data remote transmission and motor-pumped well are remotely opened and closed.
The level sensor 9 and flow sensor 10 are the parameters of water power conversion factor mode input, are rolled over according to water power
Coefficient real-time calibration model is calculated, water power conversion factor is calculated in real time, agricultural water management subsystem 1, agricultural water pipe is sent to
Manage subsystem 1 and all peasant household's water consumptions calculated according to the motor-pumped well power consumption of monitoring, be sent to basic unit and sell water subsystem 2, as with
The foundation of water inventory control.
What the present invention was realized in：Agricultural producer from basic unit sell water subsystem power purchase or purchase water, to field after pass through
IC-card swiping card mode starts water pump, and motor-pumped well water intaking monitor terminal starts to measure motor-pumped well power consumption process, and passes through GPRS communication module
Subsystem Real-time Feedback electric process is managed to agricultural water, agricultural water manages subsystem will by water power conversion factor model
Electricity is converted to water, beams back and sells water subsystem, as judge agricultural water whether overfulfil the quota and sell water inventory control according to
According to.Due to water power conversion factor and underground water watery, underground water buried depth, relevant with key elements such as electric process, according to well-irrigated area's machine
The certain proportion auxiliary construction water power conversion factor correction subsystem of well sum, realizes agricultural water management subsystem water power conversion
The real-time dynamic correcting of coefficient, can significantly improve agricultural water measuring accuracy.
The beneficial effect of motor-pumped well water metering system of the present invention is：The system is suitable for being used as iirigation water source using underground water
Well-irrigated area, compared with tradition machinery formula water meter, with frost heaving resistant, be easy to safeguard, equipment investment and the low advantage of maintenance cost；
Compared with using the water power of fixed coefficient method conversion system, motor-pumped well water metering precision can be significantly improved.The research and development of the system
The key technology difficulty that domestic agriculture motor-pumped well is effectively measured is solved, China's agricultural water managerial skills are remarkably improved.
Instant invention overcomes tradition machinery formula water meter measurement frost heaving resistant ability is poor, and ultrasonic sensor, turbine are passed
The problem of measuring equipments such as sensor input maintenance cost is high, running environment requires high, by setting up water power conversion factor syndrome
System, can dynamically adjust water power conversion factor in real time, improve water metering precision, effectively realize agricultural water metering, total amount
Control and quota management, the device have preferable application prospect.
