Story

INTRODUCTION.

Queue management systems and their potential in the times of social distancing.

VIDEO:

HOW IT WORKS

It is simply based on the formula of ultrasonic sensor.

but here formula is same but readings are different which we are going to see further in the project.the program will calculate the speed when the object is passed through the sensors and the distance between the sensors is 8 inch.So when we are calculating fps we will take (fps=666666/12) in the program. 12 is the inches of foot and 666666 is 8/12.

Both the sensors work at the same time and calculates the distance. if than distance is less than 100 than the sensor whoes reading is less than 100 led glows and a message is sent to the violators phone through twilio.and the photo of the person is captured in rpi camera module.

CONNECTIONS:

1.) connect the raspberry pi to arduino with a usb cable and use les/devttyACM0 port for serial communication between rpi and ardunio

2)rx of bolt with tx of arduino and vice versa

3)for forward ultra sonic sensor:

TRIG PIN GPIO26

ECHO PIN GPIO19

4)for backward ultra sonic sensor:

TRIG PIN GPIO17

ECHO PIN GPIO27

5)connect M1, M2, M3, M4 of arduino shiled to respective bo motors.

6)forward led and backward led to there respective ultrasonic sensor.(led are optional)

7)connect vcc and gnd of arduino shiled to bolt wifi module.

8)camera moudle to raspberry pi

9)power source:

a)power bank 10000maH

b)lipo battery 12v

c)DC 9V battery 2 in series.

A)SETUP THE ARDUINO:

#include <AFMotor.h>

AF_DCMotor motor1(1);
AF_DCMotor motor2(2);
AF_DCMotor motor3(3);
AF_DCMotor motor4(4);

void setup() {
  Serial.begin(9600); // set baud rate
  Serial.setTimeout(50);
  Serial.println("WELCOME++++");
  motor1.setSpeed(255);
  motor2.setSpeed(255);
  motor3.setSpeed(255);
  motor4.setSpeed(255);

  motor1.run(RELEASE);
  motor2.run(RELEASE);
  motor3.run(RELEASE);
  motor4.run(RELEASE);

}

void loop() {
String ch;
 if (Serial.available() > 0) {
    ch= Serial.readString();
    Serial.println(ch);
  if (ch=="F") { 
  motor1.run(FORWARD);
  motor2.run(FORWARD);
  motor3.run(FORWARD);
  motor4.run(FORWARD);
 }
 if(ch=="B"){
  motor1.run(BACKWARD);
  motor2.run(BACKWARD);
  motor3.run(BACKWARD);
  motor4.run(BACKWARD);
 }
  if(ch=="L"){
  motor1.run(FORWARD);
  motor2.run(BACKWARD);
  motor3.run(FORWARD);
  motor4.run(BACKWARD);
 }
  if(ch=="S"){
  motor1.run(RELEASE);
  motor2.run(RELEASE);
  motor3.run(RELEASE);
  motor4.run(RELEASE);
 }
  if(ch=="LF"){
  motor1.run(RELEASE);
  motor2.run(FORWARD);
  motor3.run(RELEASE);
  motor4.run(FORWARD);
 }
  if(ch=="RF"){
  motor1.run(FORWARD);
  motor2.run(RELEASE);
  motor3.run(FORWARD);
  motor4.run(RELEASE);
 }
   if(ch=="LB"){
  motor1.run(RELEASE);
  motor2.run(BACKWARD);
  motor3.run(RELEASE);
  motor4.run(BACKWARD);
 }
   if(ch=="RB"){
  motor1.run(FORWARD);
  motor2.run(RELEASE);
  motor3.run(FORWARD);
  motor4.run(RELEASE);
 }
   if(ch=="R"){
  motor1.run(BACKWARD);
  motor2.run(FORWARD);
  motor3.run(BACKWARD);
  motor4.run(FORWARD);
 }
}
}

B)setup the raspberry pi:

1)for ultrasonic forward:

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)

TRIG=17
ECHO=27

GPIO.setup(TRIG,GPIO.OUT)
GPIO.setup(ECHO,GPIO.IN)

GPIO.output(TRIG, False)
time.sleep(2)
def valf():
	GPIO.output(TRIG, True)
	time.sleep(0.00001)
	GPIO.output(TRIG, False)
	while GPIO.input(ECHO)==0:
		pulse_start = time.time()
	while GPIO.input(ECHO)==1:
		pulse_end = time.time()
	pulse_duration = pulse_end - pulse_start
	distancej = pulse_duration*17150
	distance = round(distancej, 2)
	return distance

2)for ultrasonic back:

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)

TRIG=19
ECHO=26

GPIO.setup(TRIG,GPIO.OUT)
GPIO.setup(ECHO,GPIO.IN)

GPIO.output(TRIG, False)
time.sleep(2)
def valb():
	GPIO.output(TRIG, True)
	time.sleep(0.00001)
	GPIO.output(TRIG, False)
	while GPIO.input(ECHO)==0:
		pulse_start = time.time()
	while GPIO.input(ECHO)==1:
		pulse_end = time.time()
	pulse_duration = pulse_end - pulse_start
	distancem = pulse_duration*17150
	distance = round(distancem, 2)
	return distance

3)for message service:

import boltcrd
from boltiot import Sms, Bolt
import json, time 
import credentials

mybolt = Bolt(boltcrd.api_key, boltcrd.device_id)

sms = Sms(credentials.account_sid,credentials.auth_token,credentials.my_mobile,credentials.my_cell)
def sendit():
    while True:
        print ("Reading sensor value")
        response = mybolt.digitalRead('0')
        data = json.loads(response)
        print("Sensor value is: " + str(data['value']))
        try:
            sensor_value = int(data['value'])
            if sensor_value<=100:
                print("Making request to Twilio to send a SMS ")          
                response = sms.send_sms("maintain social distance" +str(sensor_value))
                print("Response received from Twilio is: " + str(response))
                print("Status of SMS at Twilio is :" + str(response.status))

        except Exception as e:
            print ("Error occured: Below are the details")
            print (e)
        time.sleep(10)

NOTE:create a boltcrd which have your API_KEY and BOLTID

AND credentials for twilio.

3)the main code:

from ultrab import valb
from ultraf import valf
import RPi.GPIO as GPIO
import time
from picamera import PiCamera
from servercode import sendit
GPIO.setmode(GPIO.BCM)
ledb=21
ledf=22
GPIO.setup(ledb,GPIO.OUT)
GPIO.setup(ledf,GPIO.OUT)
while True:
   try:
       x=valb()
       print(x)
       y=valf()
       print(y)
       if x<=100 or y<=100:
          print("got it")
          camera=PiCamera()
          camera.capture("pritam.jpg")
          print("captured")
          if x>=y:
             GPIO.output(ledb, True)
             time.sleep(5)
             GPIO.output(ledb, False)
          if y>=x:
             GPIO.output(ledf, True)
             time.sleep(5)
             GPIO.output(ledf, False)   
          sendit()
   except:
      GPIO.cleanup()
