AUTOMATIC TRANSFER SWITCH UNTUK RUMAH TINGGAL SEDERHANA BERBASIS ARDUINO NANO

Automatic Transfer Switch (ATS) is a device that can move the main power source to a backup power source automatically and quickly when the main power source experiences a disturbance or cut-off of supply to the load. In this study, ATS was designed based on the Arduino Nano microcontroller as an automatic control that works based on voltage readings. Using the Arduino Nano microcontroller can facilitate the process of making tools and minimize the use of components. This ATS uses the PZEM-004T voltage sensor module. The voltage sensor module functions to detect and measure the value of the PLN voltage. From the test results, it was found that the time lag between the PLN supply being cut off until the generator was turned on and ready to load was an average of 2.76 seconds. Meanwhile, the time lag when the PLN supply turns on again until the generator supply is cut off and the load supply is again served by PLN is an average of 1.74 seconds. All working status of this ATS panel can be displayed on the LCD indicator, indicator light and analog voltmeter.

A General Addiction Model Based on the Theory of Demand Degree—Taking the Simulation of Cigarette Addiction through Artificial Intelligence as an Example

Objectives: As one of the mathematical results of the theory of value philosophy, the theory of demand degree can propose a new interpretation model for addiction. The theory of demand degree believes that human demands can be divided into two types, namely, the demand amount and the demand degree, and the equilibrium point of the demand degree constitutes the main basis for people to compare different types of demands and calculate the demand amount. The addiction model based on the theory of demand degree believes that addiction should have two basic conditions: firstly, the unit addictive substance is of great value to the subject, and it is the reason for the brain reward mechanism in the addiction; secondly, an addiction index is constructed, and only when the addiction index is greater than 0, the subject has the possibility for addiction. The construction of addiction index provides a standard for examining whether a certain substance can make people addicted. Converting the relevant formulas of the addiction model into artificial intelligence codes enables artificial intelligence to simulate the phenomenon of addiction. According to the change in the indicator light on the MCU development board, it is possible to judge whether the artificial intelligence chooses to load cigarettes or charge, and simulate the cigarette addiction when the addiction index is 1. The results of simulating addiction through artificial intelligence are generally consistent with the general situation of addiction, especially cigarette addiction. This indicates that the addiction model has great rationality and universality, and further indicates that without considering the harmfulness of the addictive substance, addiction is not necessarily a disease, but may just be a normal response of the human demand system to the addictive substance.

Optimization of control power sources and island driver system design for remotely operated vehicle (ROV)

Remotely Operated Vehicle (ROV) diving equipment system is an important device in oil and gas exploration and production, especially in the conditions of working in deep and complex waters. By design, the ROV Panther Plus 932 has no reverse steering function, limited visibility and difficult operation. To overcome that shortcoming, the authors have studied and fabricated an electronic circuit to take charge of the power reversing function on the Joystick with a function button and a Forward/Revert status indicator light. After adjusting, designing, controlling the ROV in the opposite direction, there is no need to turn the head, avoid twisting, burning cables, getting caught in obstacles or being caught up in the ROV during work, increasing cable life.

Hygienic Standardization of Daylight: Problems, Tasks, and International Experience (Literature Review)

Purpose. The purpose of the study was to analyze world experience and international practice of regulating natural lighting at schools and innovative solutions in this field. Results and discussions. The article presents the list of regulations of European countries regarding standard requirements for daylight and artificial lighting in residential and public buildings. The Daylight Factor (DF), which is the equivalent of the Russian natural illumination coefficient, varies from 0.8 to 5 per cent in different countries. The article describes lighting and insolation requirements for the daylight factor, light coefficient, combined discomfort indicator, light transmission coefficient, and light flux distribution in residential and public buildings, including comprehensive schools, in such countries as the United Kingdom, Germany, Greece, Poland, USA, Sweden, Cyprus, Netherlands, and Japan. The list of rated parameters of daylight both in the Russian Federation and in foreign countries is identical. At the same time, the requirements for natural lighting (DF, duration of insolation) in European standards are more stringent. The impact of daylight on schoolchildren’s health and performance was the subject of research in Sweden and the United States. Their authors concluded that studying in classrooms without daylight could disrupt the basic hormonal background, affect the ability of children to concentrate attention and interact with each other, influence growth and the number of days missed due to illness. Сonclusions. The analysis of international data proving the importance of daylight in forming optimal conditions for education and eyesight of schoolchildren and preventing health disorders enabled us to conclude on the necessity to launch scientific research into mathematical models of health risks for schoolchildren.

Digital Speedometers and Wireless Indicator Lights on Cyclist Jackets

– Bicycles has become the best solution to be able to reduce the level of congestion for the citizens of the world. Cycling is an activity carried out by someone to be able to go from place to destination and cycling has also become a hobby for some people. Even so, bicycles also experience infrastructure problems, namely bicycle lanes which are still rarely available. Some countries in the world have not fully provide special lanes for bicycle users. This causes bicycle users to use highways that are more often used by other vehicles. And it can cause accidents for bicycle users. Therefore, in the implementation of the wireless indicator lights on this jacket, the author wants to provide a better solution to overcome this problem, that is by combining indicator lights with jackets so that it can function to signal to other road users. In Addition, the author also designed a digital speedometer that can later appear on the LCD screen (liquid crystal display). For this speedometer, by placing a magnetic sensor on the forks as a magnetic speed reader placed on the bicycle spokes. For indicator lights on this jacket, the input uses a touch sensor and brake levers will be attached to the front of the bike through the bluetooth master transmission system and the bluetooth slave on the jacket, so the indicator light on the jacket will light up and form the right, left or stop direction and will be displayed on the LCD with the digital speedometer.Keyword : Speedometer, Bluetooth, Bicycle, Indicator Light, Wireless
