Essay: ADVANCE ELEVATOR – a project report

ABSTRACT
The utility model discloses to the field of elevator technology, more particularly to security, fire safety, water level detection and prevention of overload situation in an elevator. A confidential government institute carrying secret operations requires high tech security so that the details of the operations do not get leaked. In such cases security is of prime importance. Also hospitals, malls, residential and commercial buildings frequently suffer from massive fire broke situations in which many people dies. Many a times during monsoon season some amount of water gets accumulated at the ground floor which restricts the normal operation of elevator also during this situation the elevator suffers from corrosion, non-operating condition. Overload is another major problem related to elevators. Thus there is a need to add some useful features to the current system of elevators. We therefore intend to aid in security, fire safety with some useful features for elevators. Security will be provided by bringing in Finger print identification module that will only allow the authorized users to access the elevator, to access the elevator the user first has to enrol his fingers that will be stored in the memory if fingerprint identification module and then at the time of usage there is only a need to provide the finger once. To have fire safety photodiode will be used that will detect the fire in the range of 10cm, an assembly of wires connected to controller through invertor IC will be used that provides the knowledge of water accumulation at ground floor. IR sensor will be used as entry-exit sensors as a person counter. The project involves the use of pic-controller, dc motor, gsm, sensor and c-programming language. From this project we hope to provide features such as safety and security to the users.

CHAPTER-1 INTRODUCTION
1.1 PROJECT SUMMARY
Advance Elevator is modification in the current system of elevators by the addition of features such as fingerprint scanning, fire safety, sensors for detecting overload condition, simple wire assembly for detecting water at ground floor, all these is for security and safety of users.
Very often we read in newspapers about the accidents related to elevators. Sometimes due to power cut-off people get stuck between two floors or sometimes they face problem during fire emergency. In rainy season, water at ground level causes damage to the elevator by causing corrosion or leading it to be in non-operating condition. In such situation, in multi-storeyed buildings users have to use stairs.
1.2 MOTIVATION AND INSPIRATION
MOTIVATION
Recently at least 7 people died and around 28 were injured in massive fire that broke out in 21 storeyed residential building in Mumbai. Now 5 out of 7 people who have died were on the 14th floor and the fire was on the 13th floor, so during fire they have decided to use elevator for escaping to the ground floor, but unfortunately they have died even before the fire brigade could reach the spot. The dead bodies were found inside the elevator. So this incident has motivated us to work on this project.
INSPIRATION
Most of us love to watch movies in free time. Now as a technical student we get easily inspired by the way technologies used in movies. So during watching an Hollywood movie named “CAPTAIN AMERICA”, we were highly impressed by idea of Artificial Intelligence based Elevator” for security purpose.

1.3 PROJECT PURPOSE
Our purpose is to improve the quality of basic elevators by providing it with improved security and safety features that are cost effective also. So that abnormal conditions/situations can be minimized.
As we know, 21st century is known as century of technology yet India is still a developing country because we are deprived of latest technologies used elsewhere in the world. This elevator will allow the users to make better and safe use of it.

1.9 FINGERPRINT IDENTIFICATION MODULE
Fig. 5 Fingerprint identification module
UCET Page 6
ADVANCE ELEVATOR GROUP 1
1.9.1 Operation principle
Fingerprint processing includes two parts: fingerprint enrolment and fingerprint matching (the matching can be 1:1 or 1: N).When enrolling, user needs to enter the finger two times. The system will process the two time finger images, generate a template of the finger based on processing results and store the template. When matching, user enters the finger through optical sensor and system will generate a template of the finger and compare it with templates of the finger library. For 1:1 matching, system will compare the live finger with specific template designated in the Module; for 1:N matching, or searching, system will search the whole finger library for the matching finger. In both circumstances, system will return the matching result, success or failure.

Inputs and Outputs of Sensor
Input: Two ways to trigger the function of fingerprint sensor
1. Onboard switch: Add, Empty or Search.
2. Make pin low from external microcontroller for 5ms as per function required to be executed.
Outputs (Response): Two ways to monitor output response after a function is
executed
1. Onboard LEDs: ERROR or OK
2. Read byte after executing function
Types of function
There are namely three functions you can call for the fingerprint sensor. We will see each in brief.
Add (Enroll) Function: Add’s a fingerprint to database and return a byte of newly added ID. Return values are from 0x00 to 0xFE. In case of error like no finger placed, return code is 0xFF. Here 0xFF means error executing function
Search Function: When a finger is put and search funtion is called, it returns a matching ID if found in its existing memory. Return values are from 0x00 to 0xFE. In case of error like no finger placed, return code is 0xFF. Here 0xFF means error executing function.
Empty Function: When you wish to empty all fingerprint data stored on sensor you can use this function. After executing this function, you will get 0xCC as OK or 0xFF in case of error.

1.11.1 Introduction
 IR Sensor is an electronic device that detects IR radiation falling on it.
 Combination of LED (IR transmitter) and Photodiode (IR receiver).
Light emitting diode is used in IR transmitter that emits infrared radiations which is received by the IR receiver Photodiode. Atmosphere, vacuum, optical fibers can be used as infrared transmission mediums. Though IR LED look alike normal LED, radiations emitted by it is invisible to human eye.

 Ground floor wire will at logic zero.
1.12.1Working
In case of water at ground floor, ground floor wire in the water. The water level will rise slowly, as soon as water touches the wire with logic 1, logic 0 will be given to the controller via invertor IC. Once the acknowledgement is given to the controller about water detection it will not allow the elevator to go on that floor, elsewhere will be in operating condition.
1.13 DC MOTOR
Fig.11 DC motor
1.13.1Introduction
Fig 1 shows a small dc motor with its different parts. It is device that converts electrical energy into mechanical. The principle of working is that “whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force”. The direction of this force is given by Flemings left hand rule.
UCET Page 13
ADVANCE ELEVATOR GROUP 1
Fig. 12 Working of DC motor
1.13.2 Working
 When the supply is provided through relay, a magnetic field is generated around the armature. The left side of the armature is pushed away from left magnet and
drawn towards right, causing rotation.
 When the coil turns through 90°, the brushes lose contact with the commutator and the current stops flowing through the coil. However coil keeps on rotating due
to its own momentum.
 Now when the coil turns through 180°, the sides get interchanged. As a result the commutator ring C1 is now in contact with brush B2 and commutator ring C2 is in
contact with brush B1. Therefore the current continuous to flow in same direction.

ANALYSIS, DESIGN & METHODOLY
2.1 INTRODUCTION TO BUSINESS MODEL CANVAS
Fig. 14 Business model canvas
The Business Model Canvas is a strategic management and lean start up template for developing new or documenting existing business models It is a visual chart with elements describing a firm\’s or product\’s value proposition, infrastructure, customers, and finances. It assists firms in aligning their activities by illustrating potential trade-offs.
The Business Model Canvas can be printed out on a large surface so groups of people can jointly start sketching and discussing business model elements with post-it note notes or board markers. It is a hands-on tool that fosters understanding, discussion, creativity, and analysis. The Business Model Canvas is also available in web-based software format
UCET Page 16
ADVANCE ELEVATOR GROUP 1
2.2 BUSINESS MODEL CANVAS DESCRIPTION
Formal descriptions of the business become the building blocks for its activities. With his business model design template, an enterprise can easily describe their business model.
• Infrastructure
• Key Activities: The most important activities in executing a company\’s value proposition
• Key Resources: The resources that are necessary to create value for the customer. They are considered an asset to a company, which are needed in order to sustain and support the business. These resources could be human, financial, physical and intellectual..
• Offering
• Value Propositions: The collection of products and services a business offers to meet the needs of its customers.
• The value propositions may be:
• Quantitative- price and efficiency
• Qualitative- overall customer experience and outcome
• Customers
• Customer Segments: To build an effective business model, a company must identify which customers it tries to serve. Various sets of customers can be segmented based on the different needs and attributes to ensure appropriate implementation of corporate strategy meets the characteristics of selected group of clients. The different types of customer segments include:
• Mass Market: There is no specific segmentation for a company that follows the Mass Market element as the organization displays a wide view of potential clients. e.g. Car
• Niche Market: Customer segmentation based on specialized needs and characteristics of its clients. e.g. Rolex
.
UCET Page 17
ADVANCE ELEVATOR GROUP 1
• Channels: A company can deliver its value proposition to its targeted customers through different channels. Effective channels will distribute a company’s value proposition in ways that are fast, efficient and cost effective. An organization can reach its clients either through its own channels (store front), partner channels (major distributors), or a combination of both.
• Customer Relationships: To ensure the survival and success of any businesses, companies must identify the type of relationship they want to create with their customer segments. Various forms of customer relationships include:
• Personal Assistance: Assistance in a form of employee-customer interaction. Such assistance is performed either during sales, after sales, and/or both.
• Dedicated Personal Assistance: The most intimate and hands on personal assistance where a sales representative is assigned to handle all the needs and questions of a special set of clients.
• Self Service: The type of relationship that translates from the indirect interaction between the company and the clients. Here, an organization provides the tools needed for the customers to serve themselves easily and effectively.
• Automated Services: A system similar to self-service but more personalized as it has the ability to identify individual customers and his/her preferences. An example of this would be Amazon.com making book suggestion based on the characteristics of the previous book purchased.
.
• Finances
• Cost Structure: This describes the most important monetary consequences while operating under different business models. A company\’s DOC.
• Classes of Business Structures:
• Cost-Driven – This business model focuses on minimizing all costs and having no frills. e.g. SouthWest
• Value-Driven – Less concerned with cost, this business model focuses on creating value for their products and services. e.g. Louis Vuitton, Rolex
• Characteristics of Cost Structures:
UCET Page 18
ADVANCE ELEVATOR GROUP 1
• Fixed Costs – Costs are unchanged across different applications. e.g. salary, rent
• Variable Costs – These costs vary depending on the amount of production of goods or services. e.g. music festivals
• Economies of Scale – Costs go down as the amount of good are ordered or produced.
• Economies of Scope – Costs go down due to incorporating other businesses which have a direct relation to the original product.
• Revenue Streams: The way a company makes income from each customer segment. Several ways to generate a revenue stream:
• Asset Sale – (the most common type) Selling ownership rights to a physical good. e.g. Wal-Mart
• Usage Fee – Money generated from the use of a particular service e.g. UPS
• Subscription Fees – Revenue generated by selling a continuous service. e.g. Netflix
• Lending/Leasing/Renting – Giving exclusive right to an asset for a particular period of time. e.g. Leasing a Car
• Licensing – Revenue generated from charging for the use of a protected intellectual property.
• Brokerage Fees – Revenue generated from an intermediate service between 2 parties. e.g. Broker selling a house for commission
• Advertising – Revenue generated from charging fees for product advertising.

3.2 KEIL COMPILER
It is the most popular 8051 C compiler in the world. It provides more features than any other 8051 C compiler available today.
Fig. 18 Keil Compiler
The C51 compiler allows you to write microcontroller applications in C that, once compiled, have the efficiency and speed of assembly language.
3.3 MPLAB IDE
MPLAB IDE is a software program that runs on a PC to develop applications for Microchip microcontrollers. It is called an Integrated Development Environment, or IDE, because it provides a single integrated environment to develop code for embedded microcontrollers. The MPLAB IDE and Debugger is the central part of the Microchip PIC development tools. MPLAB offers a Build Mode and a Debug Mode. In the MPLAB Build Mode you maintain the project files and generate the application. MPLAB uses either the Hi-Tech or PIC ASM development tools. It provides assembler, but compiler has to be downloaded separately. Also loader has to downloaded, where pic-kit2 is the most widely used.
UCET Page 22

CONCLUSION, ADVANTAGES, FUTURE SCOPE &
REFRENCES
4.1 CONCLUSION
We achieved our objective without any hurdles i.e. the fire safety using Photo diode, water level detection at ground floor, also the Entry-Exit sensor counting persons leaving or entering; programming related to the Finger Print module has been completed. We have successfully conducted the above said definition and it’s working.
4.2 ADVANTAGES
 Provides high Security.
 Safety against Fire.
 Energy saving.
 Will not operate on Overload condition.
 Water level indication.
4.3 FUTURE SCOPE
 A system can be made based on “Artificial Intelligence”.
 If accurate voice recognition module is available in near future, elevators can be operated over voices.
