Abstract
Traditional heart
monitoring solutions exist for many years such as Holter device which records
the patient‘s ECG or the heart beats for 24 to 48 hours and is analyzed
afterwards by the cardiologists. The patient can wear the device and go home
and resume his/her normal activities. The main drawback of these solutions is
when a major incident occurs during the monitoring phase, heart rate is
recorded but no immediate action is taken to help the user. The proposed system
is an improvement in helping cardiac risk patients over the existing systems,
which also does sending messages to nearest hospital and safely parks the car
in case of emergencies.
The Proposal consists of a Heart rate monitor (HRM) that monitors the
frequency of the heart beat and checks for the Ventricular Tachycardia (VT) (a
condition that leads a person to the cardiac arrest), An Emergency Message
Sending Module (EMSM) that triggers the pre-programmed message to nearby hospital
and police station etc and an Automatic Safe Parking System (ASPS) that safely
parks the car.
The HRM consists of an ordinary stethoscope drum to piezo air-tight chamber
or stethoscope-microphone combination and wavelet filter to capture highly
accurate Heart beat pulses. This sensor module is fitted to the seat belt of
the car and is then checked for the high heart rate (VT).The sensor
module is connected with
the ECU to trigger the ASPS and EMSM modules simultaneously. The car control is
done by ASPS to safely park the car in the left hand side of the road. The ASPS
module takes care of obstacles on all sides of car, speed of the front and back
obstacles, lane observations, divider and nominal speed of the other road vehicles.
The EMSM module is also simultaneously triggered to send messages instantaneously
to pre-defined contact numbers such as nearest hospital, police station etc,
and trigger an alarm which indicates the other road users of the emergency.
Since, car is a very noisy environment; the reliability of the heart rate
signal must be focused to ensure proper detection and triggering of the EMSM
and ASPS.
Through this system, the accidents are prevented and the safety of the
driver as well as the other road users is ensured. This system also improves
safety awareness in using the seat belts while driving cars. The system triggers
a new research field of road safety and new techniques of proper communication
in case of Emergencies.
