Abstract- Emergency services and rescue services are organizations which ensure public safety and health by addressing different emergencies which improve the access to medical & health care, police and fire service, particularly attending emergency situations relating to pregnant women, neonates, parents of neonates, infant and children in situations of serious ill health and all other emergencies in the general population and thereby assist the state to achieve the critical millennium Development goals in the health sector, i.e. reduction of infant mortality rate, and maternal mortality rate etc. This paper on Emergency Service Console gives a basic idea how the emergency services can be easily called by common people when required. office so that the station will not ignore the service signal. Keywords:- Electronic Control Unit, Microcontroller Unit, Relay Logic Unit etc. I. INTRODUCTION In today s fast moving world now a days we have less time for others if they require any kind of help from us. So we have decided to make some of the emergency services handy and easily available for each and every person. Some of the emergency services are:- Police service Ambulance service Fire service Electricity service We have decided to provide a console in which each user will be provided with a UID i.e. the unique identification card that will be inserted into the console. Then the desired emergency service is selected. Accordingly the signals are transmitted to the required station. The station receives the signal and immediately responds to the corresponding service. It will also send signal to the administrative Figure 1: Emergency Services Providers By providing the emergency services we mean that suppose a user has opted for 1.1 Police Service:- If there is any theft or any sort of violence occurred in our locality, then we usually have to go to the police station and then report about it. This is very long process and time consuming. 1.2 Ambulance Service:- In any case of emergency like accidents or any sort of cardiac attack, paralytic strokes etc and if there is no phone service is available around us. 1.3 Fire service:- If any house in our locality or any factory accidently catches fire, then we can immediately go to the console, insert the card and inform the respective station about it. 1.4 Electricity service:- If there is any major shutdown, especially during rainy and summer season, people face lots of problem. Even the people 441
there do not respond to the phone calls of the customers, so at this moment this console will prove very beneficial. II. DESCRIPTION The main objective of this paper is to provide the emergency services for the poor and needy people who cannot afford for a cell phone and other luxurious facilities in case of emergency. The project uses two transmitter-receiver pair and a microcontroller which is programmed to display the information of the user using the service. The relay which acts as switch is activated when a service is requested by the user and the corresponding LED glows. III. FLOWCHART 1. Transmitter Section: Card Card Reader Figure 3: Transmitter Section Transmitter1 Keyboard Transmitter 2 The above fig. represents the transmitter section of emergency service console. It consists of several blocks as follows: a) CARD & CARD READER: We aim to provide a unique identity card (UID) to all peoples. The authority will maintain a database of residents and other data. Each card is having a unique identification for different users. Figure 4: General UID Card Figure 2: Flowchart of Project IV. BLOCK DIAGRAM The system is divided into two sections:- 1. Transmitter Section 2. Receiver Section A card reader is a data input device. A card reader is device which reads data from a cardshaped information medium. The card should be inserted into card reader. As the card is inserted into the card reader the system will start processing and it will send the information related to the each user. It s safe and convenient way to manage user s identity using a unique identification card. Nobody can manipulate this service. 442
2. RECEIVER SECTION: The receiver sections consist of microcontroller, LCD display, LED s etc. Receiver1 Microcontroller Figure 5: Console of Project b) KEYPAD: The keypad is input device. We use first four buttons as an input. These four buttons are used for selecting different emergency services. By pressing the particular button user can select the appropriate emergency services. The first numbered button is used to select the fire services. The second numbered button is used to select ambulance services. The third button is used for police services. The fourth button is used to select electricity services. Receiver2 LCD Display Figure 7: Receiver Section LED s indicating Different Services a) MICROCONTROLLER: In this project we required a microcontroller for a function of displaying the different user s name on the LCD screen. We are using 89c51 microcontroller which is a small computer on a single integrated circuit. The 89c51 microcontroller is a 40 pin IC. This microcontroller IC four ports. We are interfacing LCD display with microcontroller using port 0 of microcontroller. This microcontroller IC requires 5v DC supply. The operating frequency is 11.592 MHz Figure 6: Keyboard 443
Figure 8: Microcontroller IC Microcontrollers are also designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications. mechanism mechanically, but other operating principles are also used. In this project we required 4 relays for operating 4 different emergency services. The relays we are using are of 5 terminals. This relay has 5 terminal pins which consists of a pair of coil pins, a common pin, a normally open (NO) pin and a normally closed (NC) pin. The relay used is of single pole double throw. b) LCD DISPLAY: We required the LCD display for displaying names of the different user s. For this purpose we are using 2 16 LCD display. Figure 10: Relay The relays are interfaced with microcontroller for glowing the different LED of emergency services. V. SIMULATION RESULT 1. Transmitter Section Transmitter section consists of two parts A. Card Insertion Slot B. Keyboard Section A. Card Insertion Slot Figure 9: LCD display A liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. LCDs are more energy efficient.its low electrical power consumption enables it to be used in battery-powered electronic equipment. It is an electronically modulated optical device made up of any number of segments filled with liquid crystals and arrayed in front of a light c) RELAY: The relays are electronic device that used as switch. Many relays use an electromagnet to operate a switching Figure 11: Card Insertion Slot This is where the UID card will be inserted. Each card is having a unique identification for different users. As the card is inserted into the slot the system will start processing and it will send the information through transmitter 1. 444

LCD Display Figure 13: LCD Display Indicating Name The receiver station will receive the information send by the transmitter1. This receiver gives the information to the microcontroller through the relay logic at port 1. The microcontroller and LCD display are interfaced with each other through port 0 of microcontroller. By interfacing this, the LCD display will give the information about the user s name. Figure 15: Console of Transmitter 445
