Polar night, water pump and smart safe: 5 student projects in IoT
How can a student's IoT study project look like? What can realistically teach the student for a year, if before he did not come across this subject?
The first year of the program "IoT Academy Samsung" ended with the final of the contest held between graduates in pilot universities (MIPT and MIREA). Each of the projects that reached the final was interesting in its own way, and below I propose to get acquainted with them. This is essentially a demonstration of a range of possible topics that can be affected, based on the knowledge gained in our program.
On the competition program "IoT Academy Samsung"
On July 1? the first event that finished the academic year of the IoT Academy of Samsung - the final of the inter-university competition of projects took place for the first time. After the first half of the year, devoted to the study of study cases, the students of the course at MIREA and MIPT made their prototypes of the "Internet of things" devices for the whole second semester. The ideas of the projects were determined by the students at their own discretion, the advisers were the teachers.
At the finals, we chose the top 10 projects. Participants had only 5 minutes to speak. A full video of what happened, you can see on YouTube:
The projects were evaluated by a jury consisting of both specialist engineers and representatives of the academic community and business. The chairman of the jury is Stanislav Polonsky, head of the Advanced Research and Development Department at the Samsung Research Center, a physicist by education, Ph.D., an engineer and scientist: he has worked in the United States for more than 20 years, and his research interests are incredibly wide - from quantum chemistry to medical cybernetics. Your obedient servant was the secretary of the jury.
Nominations of the competition were as follows:
Business and society
The absolute winner is
The winners received such washers and prizes from our company.
The university-winner of the year, which is determined by the category "Absolute winner", was awarded a cup. In addition, the victory was on the side of MIREA in the nominations "Business and Society" and "Choice of Users". A student from MIPT won the nomination "Technical Excellence".
MotoGuard. Dmitry Faychuk, MIREA
This project was unanimously awarded the "Absolute Winner" prize. The author of the project Dmitry Faychuk finished the third year at the MIREA Institute of IT.
In our country, the rights of junior categories "A1" and "M" are allowed to be issued, starting from the age of 16. And many teenagers dream of their moped or scooter. For parents, it is a source of experience, especially for the safety of the child. Dmitry decided to help in resolving such situations. The task of its device is to track the location and provide the parent with information about dangerous events, such as sudden braking, impact, falling, exceeding the permitted zone. The prototype is a cardboard box, inside of which: the STM32 Nucleo L152RE board (this board is Arduino-compatible form factor, but based on the STM32 L1 microcontroller), accelerometer modules, GPS tracker, vibration sensor and GSM-communication.
It should be noted that the project of Dmitry is quite complicated in its architecture: here there is a cloud, a mobile application, and an independently written program for a microcontroller for the operating system RIOT OS.
At the competition, the jury had an obvious question: "Why not use a modern smartphone to solve the problem, because all the necessary sensors (accelerometer, gyroscope, mobile communication) are already there?". However, the author rightly noted that a separate device has a number of advantages: it can be fixed on a helmet or vehicle, make it immobile, optimize battery power, make it all-weather, and so on.
Administration of the smart safe system. Vladislav Molodtsov, MIPT.
The project was recognized as the best in the nomination "Technical Excellence". The judges were impressed by the degree of technical implementation of the prototype. Particularly struck by the fact that Vladislav was the youngest participant in the final round of the competition.
Yes, Vladislav Molodtsov is a 1-year student, but many undergraduates lack such perseverance and diligence. He made the most beautiful demonstration prototype. His safe looks absolutely like a real one, if you do not know that it is wooden.
We knew before that the students of Fiztekh differ in their approach and do not seek easy ways! One simple fact: he even assembled his own electromechanical latch on the servo for the door, simply because otherwise "it would not be so interesting."
Vladislav could not be present internally, so the presentation took place via video link
The safe has a LCD display, a matrix keyboard, an LED display showing the status of the safe (open /closed), for which a reed switch and a magnet were used. There is a speaker to raise the alarm in case of hacking. I connected all the peripherals myself, without using third-party libraries.
The graphical interface to the program is simple, but understandable. It shows the status of each safe: open, closed, locked, there is a hack.
It is assumed that such a system could be in demand by hotels, sports clubs, and just any companies where employees have personal lockers. The system does not fully elaborate security issues, which, obviously, should be the subject of further development of the project.
The system simulates weather conditions and time of day in the conditions of the polar night. Polina Rozhitskaya, MIREA
This project received a prize in the nomination "Business and Society". This nomination is undoubtedly difficult for students and teachers who do not have the necessary work experience in business, let alone on the emerging market of the Internet of things. Discussion of the jury was stormy, but in the end the opinions of the jury members agreed that the project of Polina has a real business potential.
Perhaps you've heard this advice: do not use your smartphone before going to bed? The wording is not entirely correct, because we are talking about the harm of the cold "blue" light of the smartphone screen. It is known that such light reduces in the human body the synthesis of melatonin, which is also called the sleep hormone. That's why, for example, Samsung smartphones have the option of including a blue light filter on a schedule.
And if you look at the problem more broadly? You can after all rebuild and surrounding artificial lighting so that it mimics the natural course of the sun. The task is especially important for those regions of our country where "white nights" are stunningly beautiful, but it's not easy to fall asleep. And not only! The spectrum of lighting can affect not only the sleep mode, but also the level of efficiency.
In the project, Polina proposed to do in the office a "relaxation room" in which a person can retire and turn on the lighting that is optimal from the point of view of his biorhythms. And on the employee's workplace during the day, change the color temperature dynamically, so as not to violate our natural biorhythms. Yes, and taking into account individual characteristics: larks, owls
In general, this project is from the category of those stories when inability to present their work can lead to failure. At the selection stage of the contest, it was difficult to guess from the presented materials that automatic lighting control was implemented. The video was a form with "sliders", and it seemed that this was just a trivial "smart bulb". And only additional comments from the project manager allowed us to estimate the amount of work.
Later on the final round, trainings on the skill of presentations were organized. These guys have demonstrated absolutely necessary skills in their speech and, we believe, will use them in the future.
Cargo monitoring. Alexander Filatov, MIREA
This project won in the vote of audience sympathy. With his author we have known for a long time: exactly one year ago he was a participant of the first event of the IoT Academy - Summer School on the Internet of Things, which was held at MIPT.
Now Alexander presented his system for "smart logistics", which will solve the tasks of tracking and monitoring the conditions of cargo transportation, collection of data on violations. This system can be useful for both insurance companies and freight carriers. The project implementation is simple: remote collection of sensor indicators from a tracker attached to a particular cargo, analysis of these indicators on the server and issuing them to the customer in a convenient form. The IOT-device is proposed to be equipped with the following sensors: an accelerometer, moisture sensors, vibration, tilt, temperature, and GPS-module.
Of the merits of the project can be noted user interface, the appropriate use of the Yandex-Maps API, mobile application, a competent calculation of energy consumption and the cost of system components.
The project sparked discussion on several important issues: how to guarantee wireless data transmission, if the device will be together with the cargo inside a metal container? One of the suggestions made by the jury was to develop a design that is mounted not inside but outside the container. Legal aspects were also discussed: is it possible to use the testimony of such a device in court, in the event of a dispute over liability for damage to the goods?
I must admit that my sympathies were on the side of this project and I'm very glad that the audience gave their votes just for him.
Remote control and monitoring of a group of industrial pumps. Vyacheslav Starovoitov and Kirill Komarov, MIREA
Project from the students of the Department of Promautomatics of the Institute of Information Technologies of MIREA. The problem solved by the students is very simple: there are several villages remote from the district center, with a non-permanent cellular signal. Water towers are installed for their provision with water supply. Water in them is pumped by means of pressure stations. For control of pressure stations, industrial logic controllers (PLCs) are used. To monitor their operation, an operator is required.
In the project, remote control of the pumps was implemented via a wireless connection to the PLC. The main difficulty of this type of project is to deal with third-party equipment and interfaces. To do this, it took seriously to deal with programming at a low level to control the hardware.
The guys at the competition presented a whole demonstration stand in the composition:
Programmable Logic Controller (PLC) Omron CJ1M
The frequency converter Omron VS mini J7
The engine is Siemens 1LA7050-2AA60
Unwired Devices microcontroller modules for remote control of pumps, connecting to the base station by LoRa
All interested persons could be convinced that the system regularly pumps water from the container into the bottle.
This team showed an inclination to industrial design, making cute multi-colored cases on a 3D printer. They put the final devices "Internet of things" from the training kit - microcontroller modules with buttons (for manual control of the pump), transistors (for switching loads).
Starovoitov Vyacheslav has already proved on the spring hakaton of MIREA that he is a talented interface designer. And this time, his design of the application for controlling the pumps looked laconic and stylish:
For the article, I chose, from my point of view, the most interesting projects, "there are still dozens of student works left behind", among which we can mention, for example:
Clever bath. The project differed in its original idea and aroused genuine interest and revival not only among the jury, but also among the guests of the contest. Probably, because the "bath" is an understandable theme for everyone. The essence of the project was to signal about exceeding the permissible thresholds in the room, and to monitor the state of the visitor to the bath: is it moving, or is it already unconscious?
The staff location indicator for the department head, made as a program for the "smart clock" Samsung Gear S3. A strong training project with a large amount of self-study of web programming in jаvascript.
The system of adaptive ventilation is a practical task coming from real life, and an interesting working prototype - but the solution, unfortunately, has not been worked out from the point of view of the system as a whole, and is very energy-consuming.
"Smart store" - the alignment of the light path from the shelf to the shelf, based on the current workload departments and marketing policy store.
The load monitoring system for block simulators: we add sensors to the mobile parts of the simulators and we count how many times the person does the exercise.
The mathematical model for predicting the failure of a vibration sensor on a milling machine is a very well-known task in the world of IoT, which is often solved with the help of machine learning methods. We in Russia have virtually no publications on thistopic, but abroad you can find just a few pieces 20 articles
Construction of a reservoir map based on data from ultrasonic sensors located on small mobile ships. We rejected this project because the guys focused on solving the problem within the framework of the computer model, and we still preferred real devices.
What can you say about completing the article?
A wide range of approaches and a variety of projects makes the field of the Internet of things extremely interesting. Historically, computer science and engineering were one area of knowledge: the greatest successes were made by people who were equally familiar with mathematics and circuitry, like, for example, my favorite scientist Claude Shannon. Such a synthetic course on the Internet of things is a way of overcoming the limitations of specialization. That's why for me and our teachers this course is especially valuable: here everyone can find the boundary of their knowledge and try to get out for it.
The following fact was noticed: the projects of students of each university had their own characteristic "face". This spring in MIPT and MIREA passed its additional course on microcontrollers. And it was interesting from the side to observe how PhysTech ultimately demonstrated an approach that was closest to the "iron". The guys moved "from the bottom up", that is, they studied the microcontroller in terms of registers, difficult and deep plunging into the material. And in MIREA, the study went from "top to bottom", that is, from working in the real-time operating system RIOT on the microcontroller to a "down" dive.
On hakatonon on the Internet of things in MIPT this spring
As a result, this difference affected most student projects: graduates of our program at MIPT paid the most attention to the final device on the microcontroller, achieving maximum efficiency and speed, while MIREA students made higher-level systems, usually with a more user-friendly interface, mobile application, server part.
Each of the approaches has the right to exist, because it can be useful for working as different specialists and for different purposes, whether it's rapid prototyping and production. In general, we are satisfied with the technical level of work, the program of the course the guys have mastered. In just a year they plunged into a completely new topic for themselves and acquired missing in their profile knowledge. In MIREA, several students have mastered the material so well and were fascinated by the subject that this year they volunteered to assist the teachers.
And finally, a pleasant result of the survey on the results of the academic year:
For the submitted projects, the business aspects were not sufficiently developed. For example, some authors very vaguely imagined who could be the seller of this kind of device, and who by the buyer, how the device can be integrated with existing solutions on the market. Many lacked the ability to present the project.
For the sake of justice, it should be noted that these systemic problems are not only characteristic of student-level projects, my colleagues are faced with this in their daily work.
The last final of the contest allowed us to see the results of the program and, like a litmus test, showed those moments over which it is worth working. We, having rolled up our sleeves, will take over them in the coming academic year.
With the beginning of the school year, comrades!
