Multi Plot Motor Controller

Parth Infotech provides A smater way to manage the multiple farm irrigation system via controllers.

Parth Infotech's smart irrigation control system is designed to help farmers automate and optimize their irrigation processes. Our system provides real-time control over the water flow, allowing farmers to customize their irrigation schedule and monitor the water usage. The system also features automated leak detection, ensuring that the water is used efficiently and reducing the risk of water wastage. Additionally, the system can be connected to other sensors and devices, allowing for easy integration of weather and soil data for improved irrigation. This can help farmers save time, money, and water, while increasing crop yields.

Multiplot system is a conceptualize modular design for big farm, where this farm is divided in to multiple small farms called as plot. Pump motor controller for multiplot is a device used to control pump motor for multiplot system. This device is usually different from traditional motor controller in many ways. This motor controller can be control by using mobile application installed on the farmer mobile phone. The android mobile application automatically calculates the water uses called irrigation time individually for each plot. This irrigation time for each plot can be sent to motor controller. This motor controller switch on the connected motor for the summation of time interval for all the individual plots. This smart device has some additional features like dry run protection, power fluctuation protection etc. Each plot has separate solenoid valve controller unit which receives its irrigation time interval and priority sequence wirelessly from motor controller.

·        This motor controller is suitable for single phase as well as three phase pump motors.

·        It is operated via DOL starter connected in between pump motor and this device.

·        It efficiently makes sure the water is used as needed. It also ensures optimum electricity uses.

·        The mobile application uses a highly efficient algorithm to calculate irrigation time for each plot. On top of that the farmer can also edit irrigation time for all individual plots hence provide full flexibility.

·        The dry run protection is achieved using current sensor connected in one of the motor outgoing wire.

·        Phase protection device is connected to the three-phase supply to ensure power failure protection.

·        There is a wireless connectivity between pump motor controller and individual solenoid valve controller. This wireless communication uses LoRa (long range) communication protocol with star topology network design for each plot.

Operation of multiplot motor controller

Procedure

1. Place any SIM card with activated internet pack in to the SIM card slot provided in the control panel.
2. Make sure the external antenna should be put in vertical direction and as far as possible from any sharp metallic object and the power source/control panel.
3. Connect three phase power supply to L1, L2, L3, N, E labelled motor controller connector.
4. Connect DOL starter to 1, 2, 3 labelled motor controller connectors.
5. Connect sensor to -S and S labelled motor controller connector.
6. The clamp side of sensor should be put across any one of the three wire of motor controller.
7. Please make sure all terminal connectors are tightly connected.
8. Switch on the power supply of control panel.
9. Wait for network status LED to turn ON.
10. Switch on all the solenoid valve  controller for each plot.
11. Open android application and send the irrigation time for each plot to motor controller.
12. The irrigation time for all the plots should be immediately display on the LCD of motor controller.
13. The motor status indicator LED should be turn ON and at this time the pump motor starts running.
14. At this point the irrigation of plot should happen according to priority sequence.
15. If there is no water in the well (water source), the motor stops running and hence it saves electricity and motor damage.
16. The DRY RUN protection LED status turn ON.
17. If power cut is found in between operation then immediately after power on, the remaining irrigation time will be executed by the motor controller.
