I INTRODUCTION
In the face of climate change and the depletion of water resources in the world in general as well as in Vietnam, the problem that needs to be solved is the efficient and economical use of water in agriculture With that requirement, many economical irrigation solutions have been researched and applied in practice with high efficiency such as:
Drip irrigation system according to Israeli technology
Mist irrigation system
Smart irrigation system based on humidity sensor system
These systems are also available in Vietnam However, the authors propose a new solution for irrigation systems on a large area, and suitable for farming conditions in Vietnam, especially in the Central Highlands and Mekong Delta regions [1-3]
In our country today, in order to practice farming on a large area, modern agriculture has been taking place Due to the characteristics of the season, the climate, etc., it is possible to cultivate a part or the whole of the planned area A problem to be solved for the calculation, selection and installation of the watering system, including the pump motor capacity, water pipes, and associated accessories must be done right from the beginning, and must cover the entire area To ensure the stable operation of the irrigation pump system, the capacity and flow of irrigation water must also change accordingly when the cultivated area changes [3-4] This study was carried out based on new and modern control devices to create an automatic control system of pump capacity and flow in order to save water, save electricity, and ensure safety for the road system pipes and fittings, with high reliability, stability, easy installation and operation In particular, the system can be controlled and monitored via the Internet, in line with the requirements of high-tech agricultural development,
following the IoT trend [4-6]
The system consists of 2 tanks (upper and lower tanks) set apart to create flow pressure The upper tank has a manually controlled valve to discharge water to the lower tank with different flow rates Water is pumped from the lower tank to the upper tank by a pump with a capacity of 350w, rotated by a 3ph 220v, 50hz, 370w asynchronous motor controlled by a V20 inverter with corresponding specifications The flow and pressure of the water pumped up depends on the speed of the pump motor The system outlet water pressure is measured
by a 0 – 1bar, 4 -20mA water pressure sensor The whole system is controlled by the Logo controller! 8 and monitored using Logo! Web Editor

Figure 2 Diagram of the control principle of the pump system The frame of the system:
The model frame part is made of 300 square box iron, welded together as in figure 3
Figure 3: Design of the model frame Upper and lower tubs:
The two tanks have equal volume and are made of glass material to easily observe the water level in the tub With size D=400mm (length of tub) R = 400mm (width of tub) H = 400 mm (height of the tub), so the volume
of the tub is:
V = D*R*H = 400*400*400 = 0.064 m3 = 64 liters
Complete system:
The complete level control system includes:
Base frame to hold the tub
Trang 3The pump is placed in the lower tank and pumped to the upper tank through the PVC pipe The pipeline system
is extended to the bottom of the upper tank to reduce the possibility of water waves caused by the pump to interfere with the measurement results of the system

III DISCUSSION
Using and applying Logo!8 and inverter into the automatic pumping system can solve the requirements set for the solution, and at the same time meet the technical requirements with stability and reliability high, low cost, especially can be controlled and monitored via the Internet Because the new solution is tested on an experimental model, when implementing on real projects, it is necessary to accurately calculate the capacity, pump flow, pressure adjustment range, etc Webserver control and monitoring solution needs to connect to the global internet through IT network solutions From the initial idea and learning about existing equipment and techniques, the author team selected and applied Logo!8 for the smart water pumping system, to the implementation of the real model Proposing a new solution for automatic control of irrigation pumping systems in agriculture to save water, electricity, and limit the possibility of damage to pipes and associated accessories Design and manufacture a water pump system that can be controlled and monitored via the Internet…etc Using and applying Logo!8 into the water pump system can meet the technical requirements with high stability and reliability, low cost, especially can be controlled and monitored via the Internet Build a model for students to practice close to reality
Trang 4IV CONCLUSION
The solution meets the actual technical requirements needed for an installed or installed irrigation water pump system in agriculture at present and in the future Meet the trend of industrial development 4.0 – IoT with device logo! 8 with webserver application, smartphone app Can be used in both sprinkler or drip irrigation systems with the direct pump solution Ability of the system to work with stability and reliability of the control system compared to systems using microcontrollers, low cost compared to specialized systems
