CHAPTER 1: INTRODUCTION

1.1 Introduce to the subject

Now, along with the strong development of the science and technology, electronic engineering technology Especially, automatic control technology plays an important role in all fields of science and technology, management So, as the student

in mechatronics, we have to know and use it effectively to contribute to the development of technical science world In addition, it is the promotion of the economy development of the country

As we know, all almost greenhouse in the world use rudimentary and backward technologies Jobs such as fertilizing, watering plants must be through human hands Particularly with the weather issues such as temperature, humidity, brightness, wind speed are highly dependent on weather Therefore, the quality and productivity of agricultural products are not bad, but it takes too much labor, time and cost Greenhouse was born to meet the above needs

With automation in the features, peoples just need to monitor via the Website,

or directly control the Web The system automatically collects data for analysis to ensure that data is not lost and to optimize the system All features of the greenhouse are capable of self-operation or under users control via mobile phones using 3G or Internet and provide a variety of usage modes Users can monitor and control the

soil moisture, pH, brightness

From the practicals requirements, the increasing demands of that life, together with the cooperation and strong development of the mobile network, I choose the topic of "Designing greenhouse control and monitoring models intelligent use of IoT (Internet of Things) [8] "to meet the increasing needs of people and contribute to the progress, civilization, modern country and on a par with the world

1.2 The scientific significance of the topic

Today, with the development of science and technology, electrical and electronic devices are more and more in terms of types and usability In addition, the demand for automated devices are increasing, and the people want to increase entertainment and living facilities with more and more modern technology However, the smart greenhouses have not been invested and developed

From these actural demands, we would like to include some of the world's modern techniques applied to the actual conditions in the country in recent years of growing up that are the idea of controlling and monitoring greenhouses from far from birth, to meet the increasing needs of people The theme is based on using the Website

to control and monitor the greenhouse, automatically collecting data to optimize the system and increase plant productivity and efficiency With auto mode, the people just need to monitor and don’t need to control any process Using the Website to control the device has the advantage of cost saving, competitive and apply to many different objects in civil as well as in industry

1.3 Purpose of the study and its limitations

The project was studied, surveyed and implemented for the purpose of applying the knowledge by learning in the school and spending many years of practical experience such as remote monitoring and control of equipment, actual operation of the greenhouse So, I choose to "Design Intelligent Greenhouse Control and Monitoring Model using Internet of Things" with the desire to bring benefits, safety and quality of life in the country and foreign

Intelligent greenhouses are not only functional multipurpose systems, modern and economical, but also aim to improve the life of people's utilities, especially to ensure the safety of health in the state of spilled vegetables spread anywhere

1.4 Research situation at home and abroad

1.4.1 Foreign

In the world, the development of information technology and telecommunication the developed countries, controlling and monitoring is not difficult to implement and widely replicated However, the smart greenhouse has not grown expansively yet, the practical reach is enormous Some large countries, for example, the Netherland have applied IoT [9] technology to greenhouse and gained practical benefits

Figure 1 1 Some smart greenhouse functions

Users only use their mobile phones (smartphone) or computer which can monitor and control industrial and agricultural applications such as:

Factory machinery

Waste water treatment system

Irrigation agriculture

Fireplaces, chillers, air conditioners

Other household appliances: light, fan, pump, motor

According to agricultural scientists in Israel, hi-tech greenhouses are greenhouses that utilize high technology, advanced/modern technology in the public sector Related technology to create the desired ecological environment, the most favorable ecological environment can make plant growth; Is to implement high-intensive technology; to minimize even the detrimental external factors of production

To produce agricultural products that are not favored by nature (even in the out of season), even they are not produced in the natural environment (such as the production of button mushroom in the desert); To maximize productivity, product quality and production efficiency; minimize production costs and specially to save water, because the water is considered "white gold" in Israel

Greenhouse farming is known as a key technology solution in the development

of hi-tech agriculture, is the development and make breakthrought in the development

of the "civilization of agriculture." The goal of greenhouse farming is raising or creating breakthroughs about productivity, product quality, minimizing risks in production; and to achieve the goal for producers is increasing production, production quality and ultimately the goal of economic efficiency and value of income/unit area

or investment capital On the individual farms or in areas with limited production and irrigation water supplies, the greenhouse solution is becoming increasingly important Therefore, the technology of greenhouse cultivation is opening the potential and prospects for the development of "urban agriculture"

In addition to the objective of producing "clean" and “safe” for using, greenhouse cultivation has created a revolution in productivity for crops Thanks to greenhouse cultivation, tomato yield in Israel reached 500 tonnes/ha or 3 million roses/ha, and thanks to the greenhouse technology that Israel has turned the desert sandy Negev (accounting for 65% of the country) into a "hi-tech green field" with the highest crop yields in the world Over the past few decades, Israel greenhouses are mainly used for the cultivation of flowers, vegetables, food crops/crops for highest quality products, such as peppers, onions, garlic, melons, etc At present, Israel is

developing a type of greenhouse used to produce a few ornamental and perennial fruit trees for commercial and export purposes such as grapes, apples, peaches, pears, etc

In recent years, the type of greenhouse technology in Israel has been constantly developed to raise the level of technology to meet more detailed and diversified demands for hi-tech agricultural production Along with promoting greenhouse technology for the growing industry, Israel has recently developed several types of greenhouses used in the livestock sector, mainly for poultry and aquaculture high technology in the desert

The Israel hi-tech greenhouse, in addition to ensuring a durable structural requirement, is required to perform the highest levels of mechanization of production steps, the greenhouse may also allow for the highest levels of response The need to control "greenhouse microclimate "; Control "greenhouse biology"; Control

"greenhouse pests"; And implement computerized measures to regulate the ecological environment of the greenhouse

Structure and structure: The structure and structure of the greenhouse should ensure the principle of hard, heavy, sustainable enough to withstand strong winds (depending on local climate) At present, Israel uses all types of advanced greenhouses Common parts of a standard greenhouse are curtain systems; "Light gates" and grid shading; Control systems and regulate the ecological environment to create an optimal ecological environment that meets the physiological needs of plants, such as temperature control and control systems; Humidity/humidity control and humidity control system; Lighting control and control system; Ventilation system, etc the development of integrated technology, Israel is concentrating on exploiting and utilizing the characteristic features of "smart materials" to build greenhouses

Greenhouses should firstly be able to meet the high standards of physiology and biomass of each specific crop (creating an ecologically-friendly environment for plant growth) Greenhouse height is also a factor that facilitates ventilation and

facilitates the suitability of crops The greenhouse should ensure and meet all technical standards and requirements, meet the requirements for care, technical management of production, plant protection, etc., such as Standards to prevent insects, prevent viruses, invasive bacteria, disease, etc And in particular, the height

of the greenhouse sometimes depends on the height of the machines, the equipment, the vehicles operating in the greenhouse -carrying out crop care/harvesting, increase labor productivity In terms of stiffness, in Israel the stiffness of the greenhouse should be standard: "It can withstand winds of at least 150 km/h." However, for greenhouses exported to countries around the world, stiffness and other standards often outstrip the standard or produce according to the specific criteria of the order

Technology for hi-tech greenhouses climate control: Israel greenhouses must meet certain regulatory technology standards, such as the " During the day and warm

up at night " The design and construction of a greenhouse is in such a way that the control and adjustment of environmental factors to create the "optimum sub-climate" for crops grows while only " Minimum energy " Because producers can not produce

at any cost Normally, the temperature control is usually combined with the humidity control and is carried out through the "spray system." The "spray nozzles" function

to absorb excess heat in the greenhouse During daytime and store this amount of heat

to warm the greenhouse at night, the control and regulation of the greenhouse temperature/humidity is constant throughout the day and night And adjust the greenhouse environment parameters, temperature and humidity sensors are installed

at various locations and directly connected to the computer to execute the commands

to irrigate, creating the ideal ecological environment for plants to grow

With regard to biotechnology control and greenhouse gases control, greenhouse biology controls a decision role in productivity, quality of agricultural products and economic efficiency of production To detect the adverse effects of different diseases, insects, "dashes" in the greenhouse, to attract and detect harmful insects that appear in the greenhouse so that plant engineers come to the decision to use appropriate plant protection measures To help crops achieve the highest percentage of fruiting possible, greenhouse bees placed in greenhouses, which are placed in greenhouses to be pollinated freely to pollinate the plants For pollinated plants such as melons, tomatoes bio-bee is an important role in pollinating - increasing fruit yield

Figure 1.2 Temperature and humidity sensors are installed at various locations and

connected to computers

About greenhouse technology: Israel is a country with early information technology, including hardware and software technology Israel is always trying to exploit applications to the highest level of advantages and advantages of information technology in the development of agricultural production For greenhouse production, all irrigation/fertilizing systems, temperature and humidity control systems, and climate control systems are implemented automatically through software systems technical manager

To make the most effective use of information technology in production, based producers, agri-engineer engineers and Israel software engineers are always the most effective Maintain a close-knit relationship to bring together "production

management software", the most advanced and optimal technology solutions possible

The system is built around a Programmable Automation Controller (PAC), APech-5000 series APEC, and programmable automation controllers to build control platforms, along with Webaccess Cloud HMI/SCADA software Employees of the orchid cooperative can track important data at any time through smartphone, iPad, and handheld devices, thereby altering the birth control parameters head of flower

System Requirements:

In the past, most environmental control systems of greenhouses growing in Taiwan used PLCs (Programmable Logic Controllers) with poor scalability, which could not connect to the Internet and cloud computing… The analysis of the database and network connectivity, the computer platform needs to be used Therefore, the PAC system with both PLC programming capabilities and PC functionality offers a better choice PAC controls the environment of the greenhouse by turning off appliances, such as fans, roofs, sprinklers, sprayers

Figure 1.4 Environmental control automation system in orchid growing orchids

The APAC system controls the greenhouse environment with the following devices:

• Sensor to detect environmental conditions such as indoor and outdoor temperature and humidity, sunlight, wind direction and speed

• Control components for executing fan control commands, opening covers, grids, water pumps and other equipment

• A server capable of analysis and calculation, connecting the sensors above, control components and other electrical equipment

• HMI/SCADA software handles input parameters from a computer, with database analysis and remote monitoring capabilities

System Description:

The Greenhouse uses an APAX-5520 Advantech programmable controller as APAX-5520, APAX-5017, APAX-5028, APAX-5045, APAC-5045, and several other I/O modules Remote sensors and control them via network cables These devices constitute a complete automation control architecture

With Advantech APAX Controller and WebAccess software, staff of orchid farms can set the greenhouse environment control parameters with an easy-to-use graphical interface The system automatically informs the lighting, temperature, humidity, air circulation, and other conditions, enabling the control components to adjust the environmental conditions inside the greenhouse

The APAX-5520 servers connect to the office computer via a network cable and connect to the cloud via 3G, wifi To monitor the conditions in the greenhouse, employees simply download and install the Advantech application on their smartphone or iPad

Conclude:

❖ The Advantech APAX control console and WebAccess software have the advantage of being cheap and easily scalable Can be easily controlled and monitored, monitored through computer, phone, tablet at any time and place

❖ By using a greenhouse management system, farmers can control flowering time, adjust output, there by improving sales and reducing market risks At the same time, the environment with optimal conditions will ensure the quality of the flowers

❖ As with orchids, automatic greenhouse gases control systems are also being developed for growing organic fruits and vegetables that increase the value of agricultural economics With climate change evolving markedly, the weather has become harsher than before Environmental monitoring, warning and control systems combined with information and communication technologies can help the agricultural sector escape the fate of "sky, land, clouds"

1.4.2 Domestic

With the rapid development of science technology and their application strategically in practice today and when Vietnam joins the WTO, we are strongly integrating into existing associations and organizations International scale, global opportunities to access, trade Integration into the world economy, that Vietnamese goods can be exported to foreign countries and vice versa, and can be imported from abroad into Vietnam, including technology items Modern equipment for production and the necessary of the people, ensuring the advanced technology in time, equivalent

to other countries in the region and worldwide

As science and technology grow, the more comfortable human life and the more widespread the application of automation, the more the topic of "Designing intelligent control and monitoring models using IoT "attracts people Greenhouse locations provide electronic controllers that can connect to the Internet, allowing

owners to remotely control or program equipment for each type of agricultural product In addition, devices can understand each other's language and interact with each other However, there are some drawbacks, as we can see, that smart greenhouse management solutions are highly dependent on the quality of telecommunications services, including telephone networks and high-speed internet Therefore, it is necessary to optimize the system with the auto function, all functions in the greenhouse will activate the auto mode when not control over the Website

In short-time, the use of greenhouse monitoring Website in Vietnam is still very new and has not come into practical application Most of the research is spontaneous research by individuals or groups who want to learn about this technology, it is not yet a professional research activity to be able to put into application However, in the era of information technology and telecommunications

is growing rapidly as it, that is not difficult for us to do that We use the Website to control in Vietnam is the basis when most computers and phones are now available

on the Website This is an advantage for the research and development of applications

in automation control

In Asia, a typical example is the intelligent glasshouse of the Ho Chi Minh City University of Technology Intelligent glasshouse is the product of the key laboratory of digital control and system engineering, Ho Chi Minh City University of Technology

Intelligent greenhouses have the ability to provide plant nutrients over time, from the control of the gas in the model (heat and light), due to the fact that it is equipped with sensors lighting and actuators such as: boiler, drip irrigation system, fog system, air conditioner, and LEDs stimulate growth

Figure 1 5 Greenhouse supports growers to care for, avoid pests and

create a suitable environment for the crop

The product is compact and easy to go into small alleys, suitable for agricultural departments, companies providing vegetables and fruits

Returning from France after six years of study and work, instead of becoming

a lecturer at a major university in Vietnam, young doctor Dao Xuan Quy choose another direction, working in the Faculty of Engineering Technology of Quang Binh University

Figure 1.6: PhD.Dao Xuan Quy introduces the model " Automatically monitors and controls the greenhouse environment using solar energy by smartphone" for students

In this place, he was passionate to research and promote creativity with his colleagues to implement the project “Automatically monitors and controls the greenhouse environment using solar energy by smartphone " to apply Used in agriculture - forestry - fishery in Quang Binh

PhD Dao Xuan Quy is a former student of the French-Vietnamese quality engineer program at the Ho Chi Minh City University of Technology and one

high-of the seven students high-of the school selected for training in France under the scholarship program goverment After defending his doctoral dissertation, he returned to Vietnam with the intention of working for a foreign corporation in Ho Chi Minh City - working in a professional environment and living with his family When

322-he came to Quang Binh province in 2014, 322-he had changed his plan

This shortage of motivation has kept the young man from staying with a single goal: to contribute his energies and intellect to contribute to the improvement of education and agriculture in this land Dry, sunny land And that is why he decided

to become a lecturer at Quang Binh University

Becoming a lecturer, he started to study the soil and climate of Quang Binh Although his PhD in automation, what he is most concerned about is how to improve the status of food contaminated with chemicals are increasingly threatening human health According to him, the demand for clean food is very important, especially clean vegetables However, the land and climate of Quang Binh are not favorable, so

it is necessary to apply science and technology to produce clean agricultural products with high economic value to promote economy, services and solidarity Especially the tourism of Quang Binh "It is unreasonable for Vietnam to be an agricultural country but to import products that it can produce In Quang Binh, people usually grow low-cost agricultural crops such as sweet potatoes, cassava and rice, while I want to experiment with growing short-term agricultural crops that provide economic value High tech and contribute to the development of tourism services such as melon, strawberry, orchid To do this, it is necessary to build a greenhouse system

Figure 1 7 Automatically monitor and control solar greenhouse environment

using smartphone

automatically to be able to control and monitor the environment, create the environment The school is similar to Da Lat for growing plants" said Quy

So, Quy together with the research team of Quang Binh University and Combros group (a group of Startup established by lecturers of Ho Chi Minh Polytechnical University) designed and successfully created the model "Automatic Monitor and control the greenhouse environment using solar energy by smartphone

" The system automatically monitors and controls the greenhouse environment through sensors: temperature, humidity, light and actuator: fan, irrigation pump, roof cover The special feature of this model is the use of clean and endless energy sources: solar, wind power and renewable energy Moreover, this model is remotely controlled

by smartphone through wireless connection so it does not require much labor and labor Currently, the model has been initially successful and is being deployed in the real world If the trial step in the real environment succeeds, the model will be replicated for the farmers to apply to the production process However, the difficulty lies in the fact that the cost of implementation is higher than traditional farming practices and farmers themselves are still reluctant to adopt the new model "Farmers are also keen to plant new plants, but if they do not, they will not To change this, it

is necessary to have the participation of 3 houses: the State, the scientist and the investor Accordingly, the State will issue guidelines, investors provide financial, scientists put technology into application in life If all these three elements are in sync, the farmers' ideas will surely change, "he said

At present, the research team is actively seeking investors to be willing to provide capital support, funding for farmers to implement and replicate this model in practice When the model is deployed, farmers can grow high economic value trees that are not allowed by Quang Binh's natural conditions

1.5 Design ideas

 Observation method: Investigate some electrical circuits from the internet to choose a design option later

 Experimental methods: From learned ideas and knowledge and work experience, incorporate teacher guidance, to develop a complete model that can be applied in practice

CHAPTER 2: OVERVIEW OF RESEARCH THESE PROJECTS 2.1 Internet of Things (IoTs)

2.1.1 Introduction

Internet of things is an idea from computer science: connecting ordinary things like lights and doors to a computer network to make them "intelligent" An embedded system or a computer connects each thing together in a network and to the internet Some technologies used for the internet of things are: RFid and meshnets The connections allow each thing to collect and exchange data, and we can control them remotely or by setting rules or chains of actions

IoT is simply the network of interconnected things/devices which are embedded with sensors, software, network connectivity and necessary electronics that enables them to collect and exchange data making them responsive

More than a concept Internet of Things is essentially an architectural framework which allows integration and data exchange between the physical world and computer systems over existing network infrastructure

2.1.2 Important IoTs Components

Many people mistakenly think of IoT as an independent technology Interestingly internet of things is being enabled by the presence of other independent technologies which make fundamental components of IoT

The fundamental components that make internet of things a reality are:

➢ Hardware-Making physical objects responsive and giving them capability to

retrieve data and respond to instructions

➢ Software-Enabling the data collection, storage, processing, manipulating and

instructing

➢ Communication Infrastructure-Most important of all is the communication

infrastructure which consists of protocols and technologies which enable two physical objects to exchange data

2.1.3 Development of IoTs

As the telecommunication, sector is becoming more extensive and efficient, broadband internet is widely available With technological advancement, it is now much cheaper to produce necessary sensors with built-in wifi capabilities making connecting devices less costly

Most important, the smart phone usage has surpassed all the predicted limits and telecommunication sector is already working on its toes to keep their customers satisfied by improving their infrastructure As IoT devices need no separate communication than the existing one building IoT tech is very cheap and highly achievable

2.1.4 IoTs application to life

To put things simply any object that can be connected will be connected by the IoT This might not make sense for you on the forefront but it is of high value With interconnected devices you can better arrange your life and be more productive, safer, smarter and informed than ever before

For instance, how easy it will be for you to start your day if your alarm clock

is not only able to wake you up but also able to communicate with your brewer to inform it that you are awake at the same time notifies your geezer to start water heating Or you wearable wrist health band keeps track of your vitals to inform you when you are most productive during the day These are just few examples but applications of internet of things are numerous

On large scale transportation, healthcare, defence, environment monitoring, manufacturing and every other field you can imagine of can be benefited from IoT

It is very to conceive the whole application domain of internet of things at the moment but you can clearly understand why it is such an interesting and hot topic at the moment

2.1.5 The Challenges of IoTs

As other technology, there are challenges which make the viability of IoT doubtful Security is one of the major concerns of experts who believe virtually endless connected devices and information sharing can severely compromise one’s security and well being Unlike other hacking episodes which compromise online data and privacy with IoT devices can open gateway for an entire network to be hacked

One such flaw is well presented by Andy Greenberg on wired.com where he works with hackers to remotely kill his Jeep on the highway Another very relevant example is provided by W David Stephenson in his post Amazon Echo: is it the smart home Trojan Horse? You can estimate the amount of personal and private data the connected devices will be producing once they are on a network The major challenge for IoT tech companies is to figure out how the communication in the internet of things realm can be made truly secure

2.2 Web server

2.2.1 Introduction

A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers' HTTP clients Dedicated computers and appliances may be referred to as Web servers as well

Web server often come as part of a larger package of Internet- and related programs for serving email, downloading requests for File Transfer Protocol

intranet-(FTP) files, and building and publishing Web pages Considerations in choosing a Web server include how well it works with the operating system and other servers, its ability to handle server-side programming, security characteristics, and the particular publishing, search engine and site building tools that come with it

2.2.2 Specifications

Web server respond to the client request in either of the following two ways: Sending the file to the client associated with the requested URL

Generating response by invoking a script and communicating with database

2.3 Web services

2.3.1 Introduction

A web service is a service offered by an electronic device to another electronic device, communicating with each other via the World Wide Web In a Web service, Web technology such as HTTP, originally designed for human-to-machine communication, is utilized for machine-to-machine communication, more specifically for transferring machine readable file formats such as XML and JSON

In practice, the web service typically provides an object-oriented web-based interface

to a database server, utilized for example by another web server, or by a mobile application, that provides a users interface to the end users Another common application offered to the end users may be a mashup, where a web server consumes

several web services at different machines, and compiles the content into one users interface

2.3.2 Specifications

Webserver is a Web can contain data related to the parameters and calibration

of the equipment on the Web to help people use research and find out the cause why his crops not yet good Because of the advantages that, Webserver is a good choice for this project
