Description

DESCRIPTION

Automatic display of accident details on the police website as soon as it happens

The present invention refers to the automatic display of accident information on the police web page as soon as an accident involving a vehicle or aircraft occurs.

In particular, the present invention automatically informs the Police Department, as soon as an accident occurs with any vehicle or aircraft, displaying on the police department's website (Web page) the exact date and time of the incident, the registration number (plates) of the vehicle or the the identity of the aircraft (if desired), the coordinates (latitude and longitude) of the place where the accident occurred, the altitude at which the vehicle or aircraft was located and the speed of the vehicle or aircraft. With the display of all this information on the website of the police department, the duty officer having all the information at his disposal, will know the exact location of the incident by typing the coordinates that appeared on his computer screen in the Google Earth application.

An advantage of this invention is that in the event of an accident with any vehicle or aircraft, anywhere in the territory of any country, as long as the specific vehicle or aircraft has the electronic device presented in this invention, (a necessary condition is that the vehicle or aircraft has and router), the electronic device of the present invention will automatically be activated and will send via internet and Wi-Fi all the data of the involved vehicle or aircraft in order to display them on the website (Web page) of the police department. With the police department having the coordinates where the accident occurred, using the Google Earth application they will immediately know the exact spot where it happened (and in addition they will also know the details of the vehicle or aircraft involved - if these were sent to the police department website when initially desired) to immediately dispatch the necessary forces to assist or extricate people so as to avoid loss of life.

Operation process of the application

In every vehicle or aircraft (Figure 7) the device of the present invention (SL-Save Lives) should be installed which consists of two microcontrollers (the Arduino Uno R3 microcontroller and the ESP 8266-12E W-Fi module microcontroller) or a single microcontroller (the microcontroller ESP 8266-12E W-Fi module Development board) and a GPS module provided that the vehicle or aircraft already has a router. The device will be constantly in operation (it will be powered by the battery of the vehicle or aircraft), and the GPS unit which can communicate with at least 21 satellites, will continuously provide the microcontroller with the coordinates (latitude and longitude) of location of the vehicle or aircraft as well as the date, time and altitude where it is located and its speed.

Once the accident occurs:

a) for any vehicle, with the opening of any airbag

b) for large aircraft, by detaching at least one of the black boxes from their position

c) for a small aircraft, by breaking any of its three legs where each wheel rests,

will automatically close the switch (push button) S1 (Figure 1) or (Figure 2) for any vehicle, (Figure 3) or (Figure 4) for a large aircraft, (Figure 5) or (Figure 6) for a small aircraft and the device through the program which will work continuously will activate (as soon as the state of the input-output pin GPI014 with code D5 changes in the program - point "change input state at pin GPI014 - D5") the sending of all data that the GPS unit provides the microcontroller via the internet and Wi-Fi to the website (Web page) of the police department. All the data that the GPS unit provides to the microcontroller at the time of the accident including the vehicle registration number or the aircraft ID (if desired) will be sent and displayed on the police department's website 5 times.

The duty officer of the police station after typing the coordinates (latitude and longitude displayed on his computer screen) in the Google Earth application will know the exact spot of the incident and consequently will be able to immediately notify the nearest to his location incident units, to help or extricate people who may be trapped

Hardware Description

The following is a description of each of the components required to construct the invention.

1. Arduino Uno R3 microcontroller

It is used to load the program from the PC to the ESP8266 -12E microcontroller as well as to supply 5V voltage to the LM1117 voltage regulator.

*Alternatively in place of the ESP8266-12E Wi-Fi microcontroller we can use the ESP8266-12E Wi-Fi development board microcontroller (without using the Arduino Uno R3 microcontroller and the LM1117 3.3V voltage regulator). The ESP8266-12E Wi-Fi development board microcontroller has a USB port to connect it to the computer so that the program can be loaded from the computer to the microcontroller). Also, this microcontroller provides the required voltage of 3.3V for powering the GPS and therefore the use of the LM11173.3ν voltage regulator (Figure 2) or (Figure 4) or (Figure 6) is not required.

2. ESP8266-12E Wi-Fi module microcontroller or the ESP8266-12E Wi-Fi module development board microcontroller

The ESP8266-12E Wi-Fi module microcontroller or the ESP8266-12E W-Fi module development board microcontroller includes built-in Wi-Fi. It was originally intended as a UART to WiFi adapter, allowing other microcontrollers to connect to a W-Fi network and make simple TCP/IP connections using Hayes-style commands. The ESP8266-12E microcontroller quickly became popular as a stand-alone microcontroller due to its low price.

The ESP8266-12E microcontroller or the ESP8266-12E W-Fi module development board is used, due to its small size and W-Fi connectivity without the need for external shields like the Arduino microcontroller. Modem is kept in sleep mode, which interrupts the W-Fi connection, to consume less energy (using only 15 mA) In the present invention it is used for W-Fi communication and internet connection.

3. LM1117 3.3V voltage regulator

The LM1117 3.3 V is a low voltage regulator with a 3.3V output at 800mA of load current.

The microcontroller ESP8266-12E W-Fi module and the GPS NEW-6M-0-001 need to be powered with a voltage of 3.3V. The LM1117 3.3 V voltage regulator accepts a 5V voltage from the Arduino Uno R3 microcontroller and provides a 4V voltage at its output. GPS NEO-6M-0-001

The GPS unit NEO-6M-0-001 uses the available satellites to determine its position in real time.

To read the information that the GPS unit provides we need to decode the National Marine Electronics Association (NMEA) data into easily readable information.

The antenna of the NETH-6M-0-001 GPS unit must have a full view of the sky ensuring a straight line of connection with as many visible satellites as possible.

Obstacles such as mountains or buildings block relatively weak GPS signals.

We should point out that a GPS receiver must lock onto the signal of at least three satellites to calculate a 2-dimensional location (latitude and longitude) and track movement. In contact with four or more satellites the GPS unit can determine the user's position in three dimensions (latitude, longitude and height).

Once the GPS unit has determined its location, it can calculate other information such as speed, date, time, altitude, number of satellites it is connected to, etc.

The GPS in this application is used to continuously connect with satellites to determine the location (latitude and longitude) find the time, altitude and speed.

The NETH-6M-0-001 GPS module communicates with the ESP8266-12E Wi-Fi module microcontroller or the ESP8266-12E Wi-Fi development board microcontroller via serial communication using the TX and RX terminals.

The wiring between all the above units is shown in the drawings (Figure 1) or (Figure 3) or (Figure 5) and (Figure 2) or (Figure 4) or (Figure 6) depending on the microcontroller we will use.

Software Description

At the beginning of the program, we store in the variable “myURL” the name of the Police website, as shown below,

String myURL - 'http://MyWebSiteName.com/index.php?";

In the variable named "third" we store the registration number if it is a vehicle or the identification number if it is an aircraft (if we are interested in sending this information as well), as shown below,

String third="MMM9999";

In the variable named “iOffsetTime” we store the offset time in seconds depending on the time zone of the state in which the vehicle or aircraft is registered and in which the device is installed, as below.

int iOffsetTime=7200;

By starting up the device, through the program installed on the ESP8266-12E Wi-Fi module microcontroller or the ESP8266-12E Wi-Fi module development board microcontroller, using the Wi-Fi identity (id) and password (password) -Fi is connected to W-Fi, as below.

const char* wifild = "myIDxxxx"; //wifi Id

const char* wifiPassword = "myPassword"; //wifi password

Then, using the terminals (GPI04 and GPI05 with their respective codes D2 and D1 as RX and TX serial terminals) a serial connection with the GPS unit is achieved using the command.

SoftwareSerial SerialCon(D2, D1); // The serial connection to the GPS device

The information received from the satellites via GPS can be decoded using a simple Arduino library called TinyGPS.++

FI TinyGPS++ library provides latitude, longitude, number of satellites used, time of day, etc.

When the information is available from the GPS unit (after connecting it to a number of satellites) the desired information is stored in corresponding variables, namely :

The latitude is stored in the variable named “flatitude”, the longitude in the variable named “flongitude”, the height in the variable named “faltitude” and the speed in the variable named “fspeed”, as shown in the code snippet below.

while (SerialCon.available() > 0) //while data is available

if (gpsObject.encode(SerialCon.read())) //read GPS data

if (gpsObject. location. isValid()) //check if GPS location is valid

{

flatitude = gpsObject. location. rawLat(). deg? // Raw latitude in whole degrees longitude=gpsObject. location. rawLng(). deg? // Raw longitude in whole degrees latitude = gpsObject.altitude.meters();

fspeed = gpsObject.speed.kmph();

}

The program then reads the date and time from a server-to-server NTP (Network Time Protocol) using the NTPCIient library and stores them in the variables stcurrentDate and stcurrentTime respectively, as shown in the code section below.

timeClient.update();

//Get a time structure

unsigned long epochTime = timeClient.getEpochTime();

struct tm *ptm = gmtime ((time_t *)&epochTime);

//Get date

iDayOfMonth = ptm->tm_mday;

icurrentMonth = ptm->tm_mon+1 ;

icurrentYear = ptm->tm_year+1900;

// Get time

String formattedTime = timeClient.getFormattedTime();

icurrentHour = timeClient.getFlours();

icurrentMinute = timeClient.getMinutes();

icurrentSecond = timeClient.getSeconds();

stcurrentTime = String(icurrentHour) String(icurrentMinute)

String(icurrentSecond);

//get complete date:

stcurrentDate = String(iDayOfMonth) String(icurrentMonth) String(icurrentYear);

The ESP8266-12E Wi-Fi module microcontroller constantly has at its disposal the information provided by the GPS NEW-6M-0-001 stored in the corresponding variables as mentioned above.

The ESP8266-12E W-Fi module microcontroller continuously checks the status of push-button S1. When the state of the switch changes, i.e. when switch S1 closes, and this will happen when any vehicle airbag is deployed that has been involved in an accident or the black box has been detached from a large aircraft or at least one wheel leg of a small aircraft has broken, then automatically all the required information provided by GPS NEO-6M-0-001 are sent to the police website, as shown in the code section below.

// Check if push-button (switch S1 ) is pressed

// If push button is pressed then send data to Web page

//. change input state at pin GPI014 - D5

while (bSwitch_S1_Pressed == true)

{

first = stcurrentDate;

second = stcurrentTime;

fourth=flattitude ;

fifth=longitude;

sixth=faltitude;

seventh=fspeed;
