OVERVIEW

X-tag is a Smart IR shooting sport.In currrent related product are,

• very expensive
• Companies with large indoor environments charge up to $10 for a single game.
• Not enough game modes/options.
• Not smart enough.

• Not updatable

  Therefore In this Project we build a tag system with a central server and a mobile application.In that manner we were able to Create a updatable ,smart IR tag system.Also the cost of our system will be very lower compare to current products in the market.

GOALS

• Shoot father up to 100ft
• And make cheaper to produce
• And most importantly we want to make our system smart.

SPECIFICATIONS

• There are mainly 3 parts in this project .Xtag gun and the headband to shoot and receive IR,Xtag mobile application to Choose game modes,initialize the game and a firebase server for communicate with in the game .
• Every gun has a cababilty of shooting more than 30m and many features like LCD screen,LED lights,vibration motors.
• The headband is connected to gun with a wired connection and it receive the IR signals shoots by other players.
• Also Headband has 3 LEDs to indiacate the Team colour and Another LED to blink when get shotted.Those IR receivers and LEDs are locate in every 4 sides in the gun.
• Inizialize the gun before the match,selecting the team,battle mode are done with the help of the Xtag mobile application.Gun is connecting to the mobile using Bluetooth.
• Finding the shooter,giving scores,join to a battle are done with the help of the firebase server by connecting to it through the Xtag mobile application.
• Thanks to our system artchtecture this system is updatable(Can be added more modes more option without changing the hardware) and a smart one.

SOLUTION ARTCHTECTURE

• Every player has a head to reserve IR shots and IR gun to shoot IR.
  • when the platyer shoots he shoot with some data.They are,
    • Team ID
    • Damage
    • Player ID

  

• Every players gun is connected to the mobile application through blutooth.
• Every phonr is connected to the our server.
• Using mobile application,
  • gun is initilized.
  • game mode is selected
• Server is used to,
  • comunicate with the gamne.
    • As a example Find who is the shooter and ,giving scores are done with the help of the backend.

HARDWARE

• IR emitter

This is the heart of the this project and it is very challenging when we use IR communication for this kind of purpose

• To shoot further we Planned used high power IR
  • IR emitter - TSUS5202
  • power= 170mW , 150mA
• Since esp32 cant give 100 mA for the transistor is used
  • BD139
• and a lens is used to focus
  • Diameter about - 38mm (1.5″)

• IR receiver

* SM0038 - TSOP1738 - 38KHz IR receiver * This Moduile has built in

*  signal amplifier
*   2.5 V to 5.5 V

• LCD screen 16x2 with I2C module

* standard HD44780 * 5V

• sunder

* Buzzer Piezo Bleeper Sounder * Frequency 4kHz * power - 10mA

• vibration motor

* 10000RPM Metal Brush * DC 3.7V 5V 135mA-180mA

And also push button and RGB LED are used.

• IR circuit

• IR lens

  

• IR Receiver

SM0038 - TSOP1738 IR Receiver

1. 3 pin
2. 38KHz
3. -40 to +80C
4. 2.5 V to 5.5 V
5. binary (data)

• CONTROLLER PLATFORMS

  • NodeMCU esp32 duel core microtroller

• IR Library

  * Currently it is NEC IR protocol
   	* 38 KHz
   	* 8  bit is used  ![](/e16-3yp-smart-infared-shooting-sport/images/irshot.png)
  

• implementation

• Design seperated into several parts for the ease of 3D printing

• Fabrication circuit

• Used small circuits that are connected to the main circuit for
  • Switch buttons
  • LEDs
  • Vibrator motor
  • IR emitter
  • Buzzer
• Connections are done according to the NODE MCU esp32 datasheet

BACKEND

• Access and authentication

Using Email and a password players can register Xtag Players have to verify their Email before signed in More detail will be on testing report

* It is ideal for our Xtag mobile app.
* Cloud deployment -Firestore 
	* database helps to store real-time and synchronize game data.
* Firebase authentication library is used for authentication

• Storage

  • Cloud Firestore

  Fast performance, high availability, and security

• Database

  

  • Two main collections are used to store Player data and Match data.
  • Player collection will store records as documents according to the Used ID.
  • Match collection will store records as documents according to the Match ID.
  • Players’ details of each match will be stored as a sub collection inside the relevent match document.

• Reasons behind the database

  • When do a query search in a match, It will be efficient
  • When player want see his paset, it will be efficient
  • We can increase the efficiency of the system by deleting old match data.
  • There Are Some data in the match,which are useless later
    • Ex: isready,rescue code

MOBILE APP.

• Main Functionalities

  • How to refresh the screen when players are connected * Streams are used
  • Syncing the game time counter
  • How to set a tempid
  • How to give a score to the shooter * Query searching is done by the killed player

• User Interface - Mobile Application

  Develop using Futter 1.17

• Home page
