I. INTRODUCTION
The inspiration for this wearable originates from the expanding requirement for wellbeing for youngsters in present occasions as there can be situations of the kid losing all sense of direction in the major swarmed zones.
This paper focusses on the key perspective that lost kids can benefit from outside intervention by the general population around the tyke and can assume a huge job in the youngster's security until rejoined with the guardians. Subsequently it is proposed to utilize the SMS as the correspondence type between the parent and kid's wearable gadget, as this has less odds of falling flat when contrasted with Wi-Fi and Bluetooth. The stage on which this task will keep running on is the Arduino Uno microcontroller board dependent on the ATmega328P, and the elements of sending and getting SMS, which is given by the Arduino GSM Module utilizing the GSM
organize. Likewise, extra modules utilized which will give the present area of the youngster to the guardians by means of SMS. The second measure included is SOS Light pointer that will be modified with Arduino UNO board to show the SOS flag at whatever point the parent need. In the situation, a lost youngster can be situated by the parent could send a predefined catchphrase as a SMS to the wearable gadget which would answer back by sending area to the parent portable. Also, the wearable outfitted with a pain caution bell which sets to dynamic by sending a SMS catchphrase "BUZZ" to the wearable.
Thus the ringer is more intense and can be heard by the parent from entirely impressive separation. Additionally the guardians by means of SMS can get directions of the kid, which can enable them to find the youngster with greatest precision. A portion of the current work done on these comparable lines are for instance the minimal effort, lightweight Wristband Indispensable which faculties and reports unsafe surroundings for individuals who need prompt help, for example, youngsters and seniors. It depends on a multi-sensor Arduino smaller scale framework and a low- control Bluetooth 4.1 module. The significant downside for the Imperative band is that it utilizes Bluetooth as the method of correspondence among kid and the parent. Along these lines, the wearable gadget proposed will speak with the parent by means of SMS through GSM which would guarantee that there is a protected correspondence interface. Likewise, customization of the wearable can be conceivable according to our necessities by reconstructing the Arduino framework
II. RELATED WORKS
Aarti Rao Jaladi et al [1]The design of the youngster wellbeing wearable gadget, which portrays the different advances and innovative benchmarks that are utilized.
The Arduino Uno gathers the information from the diverse modules interfaced to it, for example, the GPS module after being activated by the Arduino Uno by getting SMS from GSM module. The GSM module is utilized as an interface to send the information gotten by the Arduino Uno by means of SMS to a portable. The GSM module works as a trigger for the Arduino Uno to ask for information from its different modules associated with it. In the event that a SMS content with determined watchword is sent to ask for the present area or GPS arranges is sent to the GSM module by means of the
client's telephone, at that point the GSM module triggers the Arduino Uno to ask for the present GPS organizes.
Hamid Shahnasser et al[2]The wearable gadget entrusted with obtaining different information from the all the diverse modules associated with it. It includes Arduino Uno dependent on the ATmega328P microcontroller. The arduinouno gets information from various modules and examination the information and tweaks the information in a client reasonable organization. For the minute the plan isn't made conservative, since the fundamental concentrate presently has been to demonstrate that this idea of keen wearables would be very effective for the wellbeing of the youngsters. The wearable framework keeps running on a battery or any outside source. So as to limit control utilization, the wearable gadget has been customized to give GPS and other data just upon demand by SMS content through GSM.The size of the raspberry pi kit is large it is converted in to a smart wearable device by embedding the software and the hardware in to a chip.The tack of the wearable device is to acquiring large and different amount of data from the connected modules. The collected data is analysed and customized for the user understanding method. It works on the battery or external sources.
H.Moustafa, H.Kenn et al[3]For deciding the constant area of the kid NEO6MV2 GPS module has been utilized which speaks with the Arduino Uno through a 9600 bps programming sequential interface. The associations between the Arduino Uno and the GPS module set up like the associations with GSM module. It has a low power utilization and little size, which is minimized. The GPS module yield includes standard string data which is represented by the National Marine Gadgets Affiliation (NMEA) convention. When the SMS trigger content "Area" is sent from the wireless of the client, this content is gotten by the GSM which thusly triggers the Arduino Uno to execute the GPS code to get the current, precise area of the GPS module. The area yield got from the GPS module is in the accompanying arrangement. To reduce the power consumption it is programmed to deliver the text message and image of the location. The SMS is transferred to the parent mobile by the GSM module.
H.Kenn et al[4]The scope and longitude facilitates got are put away in factors called "scope" and "longitude,"
which are then called upon when the SMS content got on the GSM module matches with the watchword
"Area". When the SMS trigger content "Area" is sent from the cell phone of the client, this content is gotten by the Arduino GSM Shield which thusly triggers the Arduino Uno to execute the GPS code to bring the current, precise area of the GPS module. The area yield string got from the GPS module is in the accompanying configuration. Raspberry pi have several series but in this project to use 6thseries for the implementation. It is one of the single- board computer which is developed by the united kingdom under the promote foundation. The speed of the processor is from 700 MHZ to 1.2 GHZ.
This kit even has the memory like on board memory from the range 256 MB to 1 GB. The operating system as well as program memory makes use of SDHC and Micro SD for the storage process.
P.Bhagwat et al[5]Secure Digital (SD) is like a card which is used for the storage process for the on board memory. The supported EDMI or composite video for the video output. Likewise standard 3.5 mm is used for the audio outcome from the triggered sensor devices.
The common protocols were supported by the lower- level which is provided by a number of GPIO pins. It is promoted for a basic computer science for advance developing countries. It deals with the temperature range which is enhanced in this system of development. The range of the temperature differs from place to place and hence regular monitoring of the range is needed in all smart devices.
N.Prince et al[6]The another theory that this paper focuses on is that bystanders are the first mode of help for a missing child. The purpose of the SOS light is to be able to alert the people near by that the child might be in distress since the light will be flashing the universal SOS light symbol which may people nowadays know for to be a sign for help. This can be activated by the parent itself by sending an SMS text withthe keyword “SOS”
to the child’s wearable whichwill activate the SOS light flashing. The SOS light works on the principal of Morse code in which “S” standsfor three short dotsand the “O”
stands for three long dashes. Since a very long time the SOS signal has been universally known for being the sign of distress and help. The SOS signal is referred to by all security personals, who if find the child to be missing can act and help locate the parents with surplus resources present at their disposal. The SOS light is connected to the pin of theArduino.
J.Saranya et al[7]The advanced feature is observed by Appling condition reasonable condition to the sensor.
The parent will receive a message when their children body temperature reaches a certain level which is invoked by the device. There will be a condition like maximal range and minimal range if in any case the children body temperature gets closer to the maximal range the parent will receive the intimation in the format of text message about the body temperature of the respective children. LCD stands for Liquid Crystal Display screen. It is an electronic display for the proposed module. A 16x2 display is implemented for this exiting module. The display module is connected to the various devise and even circuit. The displayed signal is converted in to a digital signal from the analogy signals with the pixel range of 5x7 pixels.
K Sai Ravitej et al[8]In the situation, if a youngster is saperated from his/her folks. The parent can find the youngster by sound in an exceptionally noisy alert on the wearable. To accomplish this, a piezoelectric signal is utilized, which is in charge of producing a solid tone upon the yield being set to HIGH. The bell module is actuated after sending a SMS content with the
watchword "BUZZ" from a phone. Likewise, this bell works like the SOS driven by cautioning the general population close-by with the upset tone that the youngster may be lost and need help. The ringer is the kid may be lost and need help. The bell is associated with the computerized stick of the arduino. The command register which is embedded in the display device will store the instruction which is given to the LCD. It is the predefined task for the display device like screen cleaning etc. The data which are represented in the ASCII values. The display device will convert that ASCII value in to a human readable language it’s the main task for the display devices. The main features of LCD is 5x6 cursor and +5V power supply which is embedded in it.
YovanFelix.A,A.Pamila et al[9]About the door of system is GSM/GPRS Modem-RS232 is worked with Double Band GSM/GPRS motor SIM900A, takes a shot at frequencies 900/1800 MHz. The Modem is accompanying RS232 interface, which permits you associate PC just as microcontroller with RS232 Chip(MAX232). The baud rate is configurable from 9600-115200 through AT order. It is appropriate for SMS, Voice just as Information move application in M2M interface. The locally available Directed Power supply enables you to interface wide range unregulated power supply . Utilizing this modem, you can make sound calls, SMS, Read SMS, go to the approaching calls and web ect through straightforward AT directions.
K.Sayrafian et al[10]Raspberry pi camera is used for the capturing of current location of their own children when they left alone. Omni vision sensor (OV5647) with fixed focus and availability of replaceable lens. The lens will focus up to M12X0.5. It may be CS mounted or only C mounted on it. The resolution of the picture is 2592x1944. Maximum picture resolution is 1080P. The frame covered by the focusing camera is 30 frames per second. The major objective of advanced raspberry camera is supporting feature like FREX/STROBE. Size of capturing area is 36x36 mm. Major applications are it is offen used in cellular phones and PDAs. Which is fixed in toys and other battery powered products for monitoring process. It can also be used in other platform like ARM and DSP platform.
J.Selvakumar et al[11]It exchanges the data over to the client by means of SMS. Arduino gives GSM libraries to GSM module too which enables the GSM module to make/get a call, send/get SMS and go about as a customer/server. The GSM module gets 5V control supply specifically from the 5V stick association at the Arduino Uno 5V. The sequential correspondence between the Arduino Uno and GSM module is performed between the sequential pins 0,1. The Arduino has been customized to get SMS instant messages from the parent's cellphone by means of GSM module. The GSM module will always be filtering the gotten instant messages for the particular watchwords, for example,
"Area", "TEMPERATURE", "SOS" and "BUZZ".
S.Sollaiet et al[12]Global positioning system is one of the major devices for monitoring exact position. The trilateration principle is a simple mathematical which is used to calculate the distance using the measure of x,y,z axis. The GPS consist of three segments they are user segment, control segment and space segment. The space segment has 24 satellites for monitoring the exact location from the earth which covers 20,200 Km from the above earth surface. The ground station is the control segment for the control access for authorization.
The working process of the satellites is monitored by the control segments. The GSP can work in two operations the first is SPS which stands for standard positioning service and the second one is PPS which stands for precise positioning service. The SPA will work under lower accuracy while PPS will work under higher accuracy. The user segments are to receive the signal from the receiver’s side.
J.Rigg et al[13]This theory is focused on LM35 is an integrated circuit for the temperature sensor. To measure the body temperature of the children LM35 type device is used. Its equipped to display the observable temperature accuracy of the device. The value of the obtained temperature is stored in the form of variable or string type. The sensor is triggered by pressing the keyword “temperature” from the display of the application.After testing the wearable gadget on numerous occasions with rehashed SMS writings. The GPS area sensor had the capacity to react back with exact scope and longitude directions of the wearable gadget to the client's cellphone, which then the client would tap on the got Google maps URL which would, in tum, open the gmaps application or any default program and show area.
S.Arun Kumar et al[14]In every one of the situations the GPS module was tried, it would react back to the client's cellphone not exactly a moment. As appeared in the picture underneath, the GPS module (red air pocket) had the capacity to demonstrate the present area of the wearable with pinpoint precision and furthermore show precisely at which side of the building it is available.
Though for blue spot is appearing wearable to be available in the city, which is possibly off from the precise area. This minimal miss coordinate in the stick point area of the wearable would tum be able to out to be deadly in a genuine situation, where the parent might be miss lead to the wrong area of the kid. Thusly, NEO6MV2 GPS module ends up being effective in furnishing the exact area with high exactness and with a decent reaction time. The main downside that could be expressed was, the GSM module couldn't translate numerous legitimate watchwords sent in a solitary message. For instance, SMS string sent:
"LOCATION","TEMPERATURE","UV","BUZZ"
AND"SOS" it would not send an answer back to the gsm module
Perappada,BinduShajan et al[15]The major aspect of SOS light is to alert the parent about the surrounding of
the children. Morse code principal is carried over in this SOS light. Were as in SOS “s” represents for three mini dots and other “o” represent the three dashes which is large. When the parent presses the key word SOS it is activated and sent a SMS text. This SMS text will activate the SOS flashing which is embedded in a light.Alarm is fixed to a wearable device. If the parent is separated from their children this part will help the parent to alert the children when they in danger zone. A specific buzzer is used to achieve effective alarm that is piezoelectric is implemented. The digital pin in the raspberry pi is connected to the buzzer. The SMS is sent when the keyword buzz is pressed from the respected parent hand mobiles. Even SOS led work is similar to the buzzer. The alarm release some sounds like distressed tone from the device which will alert the children.
III. PROPOSED SYSTEM
The initated concept implemented through this block diagram consists a set of sensors to track and monitor the child’s current location and activities.
Block Diagram
In a 40 pined Raspberry kit , the GPS is embedded for the location tracking.LM35 is the temperature sensor induced to sense the temperature to decide whether it s favourable for child or not.The new Raspi camera is mounted to capture the surroundings and update the parent about the circumstance of the child.Here an alarm buzzer is implemented in which two way notification can be done in case of any emergency situation as well as from both parent and child side.While buzzer alarms, then SOS light starts intimating the child about any emergency situation or its time to be at home.These all are connected through a network and get operated by an application with defined keywords which are the trigger words for the system to get activated and updates the parent. For location tracking, the latitude and longitude of the current location gets noted . The messages are sent through a network even the parent can receive a text message when a corresponding mobile identifier number is mentioned over there,
Camera module
Camera module is introduced as a scope of implementation. It is used for the surveillance of the current location of the children. It captures the clear image and information of the children live location. The collection of live stream location alone is stored in the data base. Whereas it doesn’t stores all the movement of the children.If the parent want to see their own children live place the key word location is pressed and the live stream is open the clear image and he video is played in the other end. Raspberry pi camera is uses which is the production of Raspberry pi group. Red and blue wires are connected to the +5v and the other blue wire is connected to the GND. Camera pin serial data is divided in to two which is the good plan for better connectivity.
5v is pin is divided in to 2.5v for the efficient purpose.
[2]Android app:
This android app has the additional features like it even transfer the message in offline mode also. The people in the rulal are may don’t have smart mobile with them. So by considering this we designed the network which will also receive and send the message when the mobile in offline. Hence the use of the network gate way is very efficient.The application of this android will also work in the offline mode. Hence it is also used for the people who is in rural area. The efficiency of the application more if its start work in offline mobile. The live streaming is captured by pressing the respected keywork which is displayed in the application. The mode of network used in this project is GSM module which is used in two way communication.
IV. CONCLUSION
The smart device for child safety will deliver the real and current location, environment temperature and even alarm is used for alerting the parent. The advanced feature like two way buzzer is implemented for the two side communication. The ARDUINO kit is replaced by RASPBERRY PI kit for efficient features for child safety. The complete process of raspberry pi kit is, it receive all the information from the sensor and module which is connected to it. Then it analyse the received data which is required. Finally it converts the data into user understandable data by costuming process. And also more efficient battery power model is introduced in this implementation. Hence it provides efficient power supply for longer time.The youngster security wearable gadget is equipped for going about as a shrewd gadget.
It furnishes guardians with the ongoing area, encompassing temperature, SOS light alongside Trouble caution signal for their youngster's environment and the capacity to find their tyke or ready onlookers in acting to save or solace the kid. The shrewd kid security wearable can be upgraded considerably more later on by utilizing profoundly smaller Arduino modules, for example, the LilyPad Arduino which can be sewed into textures.
Additionally a more power proficient model should be made which will be fit for holding the battery for a more extended time.
