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.
