Description

SECURE AND SMART HELMET INTEGRATED WITH SAS-H APPLICATION FOR DATA TRANSMISSION The innovation relates Secure and Smart Helmet (SaS-H) is designed to work along with an application which is attached to sensors on Arduino board, GPS and backend .0 server. The present invention is best explained by means of drawings. SaS-H was developed with the help of standard helmets such as Lazer Bullet 1.0, Antwerp, Lazer Sport, and Belgium. SaS-H is fixed with the temperature sensor, position sensor, IR sensor at the front, back and right inner body of helmet, exclusively for the safety of the bike rider.This collected information is sent to the health officer in the particular place. All .5 these connected sensors are linked with Arduino and data are transmitted from the helmet via Bluetooth Low Energy microcontroller and USB chargeable battery. The connected system is integrated inside the SaS-H and the geometric characteristics are not altered. SaS-H along with the sensors is connected with android-based application called "SaS-H App", which connects via Bluetooth. It was developed using AppyBuilder from App .0 Inventor. The application was designed for sending and receiving the data from the user and the contacts stored in the database. Issues exist in integration of monitoring, deploying and speed up the information transfer within a limited period. Hence, to overcome these issues we have utilized the platform named, PagerDuty. It helps to inform emergency contacts once the event is triggered. API is created using HTTP or CLI. Representation of .5 events is transferred between client-server using either JSON or XML. Steps for triggering the incidence and alert service are as follows: • Create an account in PagerDuty

• API key is generated

• Send a POST request to an API with required credentials.

• Trigger the respective incident using API. Figure 1 illustrates an exemplary embodiment of work flow of secure and smart helmet.

The working principles of the invention are as follows:

A. Sensors of SaS-H: (i) MQ3 Sensor: MQ3 sensors role is to detect whether the rider is drunk or not. It helps in detecting the presence of alcohol (i.e. ethanol in air). When the person breathes near the sensor, it shows high range of ethanol, and hence it is detected that the rider has drunk. In our designed system, while the rider starts to ride, alcohol sensor detects the condition of rider. If it is found that the rider has drunk, it sends the notification as the rider is not in the position for the journey.

(ii) Temperature Sensor: Temperature sensor is electronic devices that helps in detecting the temperature inside .0 the smart helmet and notify the rider when the threshold value is exceeded. Thermostat helps in maintaining the constant temperature inside the helmet.

(iii) Position Sensor: Position sensor helps in detecting the position of an object and analyse the variation in .5 position when titled towards a specific angle. Various technologies which include inductive, magneto resistive, potentiometric, reed switch, Hall-Effect sensors are readily available. Hence, purpose of position sensor in smart helmet is to detect the position of the rider, and if the rider tilts towards the seat or if the angle is measured below 45 degrees, position sensor senses that an accident has occurred and the required information .0 is displayed and sent to the emergency contacts in the server.

(iv)Speed Limit Sensor: Speed Limit sensor helps in detecting the speed of the vehicle up to certain level. In our designed SaS-H system, a speed limit sensor helps in analysing the speed of the .5 vehicle and displays an alert message too mobile.

(v) Infrared Sensor (IR): Infrared Sensor is used to detect characteristics of the surroundings by emitting infrared radiation. These are capable of sensing the heat reflected by an object and helps in motion detection. Hence, in our design on SaS-H system, IR sensor works with temperature sensor to analyze the temperature inside the helmet of the rider according to the rays emitted by an object.

(vi)Thermal Camera: Thermal Screening using IR thermometers are generally used in public places to check body temperatures for identifying infected persons among public. As it needs more time on screening of people, thermal imaging system integrated with smart helmet helps in faster detection. Therefore, in our SaS-H design work, thermal camera is fixed at the outer surface of the helmet and hence the body temperature can be detected at faster rate.

(vii) Optical Camera Optical camera is capable of capturing the person's image whose body temperature is .0 high. Hence, design of SaS-H is developed in such a way that optical camera helps in collecting the person's image and send the information to the Health officer.

(viii) GPS Obviously, the next step on detecting the person information and their travel history is .5 possible through GPS attached in the smart helmet. Thus, the person's travel history is then tracked with the help of Google History GPS tracker. It is then send to the concerned health office for the further steps.

B. Backend Connection: .0 Backend connection needs a database which supports user data when connected to an application. One of the most popular open and free databases is firebase, which supports real-time data for storage. Rider has to install the mobile application, in which the data are stored and categorized according to their preferences. When accident happens, location and rider's information are directly sent to the family members who are added in emergency contacts. Other data such as over speed are stored in database. The proposed SaS-H can even help the law enforcement officials to monitor the group of users for safe travel. In addition, it can be applied

C. Challenges on Alert/Notification: Few issues prevail in designing the proposed SaS-H design. It includes that the false positive value which can be received due to the sensors attached must be neglected. The main cause of this issue is the change in acceleration. For instance, when motorist drops the helmet by chance, there can be abrupt change in acceleration. In this scenario, there must be some mechanism to suppress those false positives from reaching the emergency contacts. Otherwise, it can lead to fault system along with the wastage of resources. Two wheeler accidents are caused in various situations, but the resources available are much limited. Hence, accident detection must be performed with the constraint resources in an efficient manner. When the monitoring system alerts about an accident, information has to be sent in much secure manner. If the contact did not respond to the messages, or miss the message, the system must send messages repeatedly until it get acknowledged.
