INTELLIGENT STREET LIGHTING
Home/INTELLIGENT STREET LIGHTING
Every evening, an intelligent street lighting control system has to light up at the right time and function seamlessly. A city’s street lights provide safer traffic conditions, safer pedestrian environment and can represent a great improvement to the city’s architectural, touristic and commercial output. These benefits are not exactly cheap though, with an average of 40% of the public budgets’ energy bill being spent for street lighting alone. The increasing energy price, plus the significant maintenance costs and always increasing expectations manifested by the public put a continuous pressure on the lighting budgets.
inteliLIGHT® is a remote street lighting control solution that offers you detailed, lamp-level management capabilities of every street light in your city and ensures that the right amount of light is provided where and when needed. Equally important, in-depth grid management gives an accurate real-time feedback of any change occurring along the grid, reduces both energy loss and energy surges and offers advanced maintenance optimization tools. Using the existing infrastructure, you can have live detailed information over the grid and transform the existing distribution level network into an intelligent infrastructure of the future

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Automatic room light controller with bi directional visitor counter using Arduino uno
1. Automatic room light controller with bi-
directional visitor counter using Arduino uno
Presented By ,
Mr. Prasenjit Chandrakant More
2. INTRODUCTION
• Project title is “ Automatic Room light ControllerWith Bi-DirectionalVisitor Counter Using Arduino Uno ” .
• Electricity is one of the most important resources in this century.We should conserve the electricity. But
Many times we come out side the room / hall and forget to turn off lights/fan, thus the electricity is wasted.
• To overcome this we are going to implement a project called “ Automatic Room light Controller with visitor
counter ” .This project has two modules, first modules is “visitor counter ” and second is “ Automatic room
light controller ”.
• Main concept behind this project is to measure and display the number of persons entering in any room like
seminar hall , conference room and when number of persons inside the room is zero m power supply inside
the room can be cut using a relay interface.
• This will help to save electricity , LCD display placed out side the room display number of person inside the
room.
6. CIRCUIT DIAGRAM EXPLAINATION
• Sensor Section
In this section we have used two IR sensor modules . Here in this circuit we have used two comparators for two
sensors. LM358 is used as comparator . LM 358 has in built two low noise Op-amp.
• Control Section
Arduino UNO is used for controlling whole the process of this visitor counter project. The out puts comparators are
connected to digital pins of Arduino
• Display Section
Display section contains a 16*2 LCD . This section will display the counted number of people and light status when
no one will in the room.
• Relay Driver Section
Relay driver section consist a BC547 transistor and 5volt relay for controlling the load . Arduino sends commands to
this relay driver transistor and then light bulb ( load ) will turn on/off accordingly .
7. SYSTEM IMPLEMENTATION AND TESTING
Testing is a vital process in the development and realization of any design, be it hardware based, software
based or both. The various components and their circuitry have to be tested to ensure that all the
components on board are certified okay and in good working condition. The components that did not give
the required output specification where isolated and troubleshoot to determine the nature and cause of the
component failure through careful analysis, that is examination of the working principles of the
component(s).
• Display testing
When a program to show ‘hello, world !’ is burnt into the arduino, the display shows the sentence. The
following figure shows the display test.
8. • IR Sensor testing
This section we test the sensor implementation by using an obstacle.
• Testing Relay
Here we did testing of relay before put into use in system.
9. SYSTEM IMPLEMENTATION code
&
code explanation
#include<LiquidCrystal.h>
Liquid Crystal lcd(13,12,11,10,9,8);
int In = 4;
int Out = 5;
int relay = 2;
int count=0;
The pins for LCD are
from 8 to 13. Input
pin is at 4 output pin
is at 5 and relay is
connected at pin 2.
10. void setup()
{
lcd.begin(16,2);
lcd.print("Visitor’s Counter");
delay(2000);
pinMode(In, INPUT);
pinMode(Out, INPUT);
pinMode(relay, OUTPUT);
lcd.clear();
lcd.print("Person In Room:");
Serial.begin(9600);
A loop is created which is
used for initialization of the
LCD setup. At the beginning
of the program the LCD will
display a message of
“Visitor Counter”.
11. void loop()
{
if (digitalRead(In) == LOW){
count++;
}
else if (digitalRead(Out) == LOW){
count--;
}
else if (count > 0)
{
digitalWrite(relay, HIGH);
}
else if(count <= 0){
digitalWrite(relay, LOW);
}
lcd.setCursor(0,1);
lcd.print(count);
Serial.println(count);
delay(700);
}
In loop function we read
sensors input and increment
or decrement the counting
depending upon enter or
exit operation.
12. RESULT
• There are two transmitters and two receiver
placed in front of each other. Swap any object
(like mobile) or your fingers in front of those
sensors. Then microcontroller increments or
decrements the counter. Ones the count is
nonzero, the room lights turned on using relay
and turned on fan. Now swap object in reverse
direction then the system decrements the count.
And room light turned off and the count
becomes zero.
13. ADVANTAGES
Main advantage of this project is that it helps in energy conservation. Because when there is nobody
inside the room then lights are automatically turned off.
Since this project does the automatic person counting with the help of two sensors installed on door
frame it also reduces the additional work of employee to count the persons .
Low cost because human-based data collection comes with great expense .
Also, there is no hazardous elements used in the circuit and hence it can be used even at hazardous
atmospheres in an industrial area.
14. DISADVANTAGE / DRAWBACKS
It is used only when one person cuts the rays of the sensor hence, cannot be used when two or more
persons cross the door simultaneously or a crowd entering or leaving can’t be counted by this system .
The only person who can communicate with the control module is the person who is in the receptionist
or security unit.
15. APPLICATION
It can be used in various rooms like seminar halls , where the capacity of the room is limited and
should not be exceeded.
It can be used in our homes because we often forget to switch off our room lights
It helps in energy conservation
Voice alarm system can be used to indicate that room is full & person can’t enter inside
16. FUTURE DEVELOPMENT
• We can send this data to a remote location using mobile or internet
• Voice alarm system can be added to indicate that room is full and persons
can’t enter inside.
