y, so the effects are still not perfect.
The users can also operate on the HMI screen. Besides, the operator can observe the
working status of the device, the operating modes.

Personal opinion: The HMI interface has a neat and simple design that makes it easy
for users to control the programmed effects, monitor whether the devices are working
or not. However, there are still limitations on the monitoring parameters such as
voltage, frequency.

CHAPTER VI. CONCLUSION AND RECOMMENDATIONS
6.1. Conclusion
In conclusion, after the process of implementing the model, our team has achieved the
initial proposed criteria:
-

The supporting frame withstands all the force from the water supply and drainage
system and the electrical equipment installed on the electrical panel

-

The system runs effects with continuously changing water columns.

-

The signal transmission speed between PLC and VFDs achieves accuracy and
continuity.

-

Highly entertaining

-

Easy for users to access and operate.

However, there are still drawbacks:
-

Small substances can get stuck in the solenoid valve during operation, making
this device unstable.

-

The water column is sometimes uneven due to the influence of the air in the
pipelines when opening and closing the valve.

6.2. Development
-

Can develop the system by replacing the solenoid valve technology with linear
valve in order to limit the number of inverters and pumps.

-

Installing some more nozzles to more different effects to increase the
aesthetics of the system

-

Using remote monitoring and control software such as Web Server to be able to
manage the operation of the system without approaching the system.
