Problem:
It becomes a vital necessity to monitor our old ones in
order to keep them safe and healthy. People at old age mainly suffer from a
severe problem to walk due to the fact that the bone joint become weak as they
become old. This leads to the people to be bound by a wheelchair. Even though
they are bound by wheelchair they have a great
risk of falling down. So it is important to know if they have fallen or not
so that a timely help or treatment can be provided to prevent them from further
danger.
Solution:
In order to do this
we propose a sensorized moving aid for
old aged persons and also differently abled persons. Here a gyro sensor and
accelerometer is employed to detect the abrupt movement of those persons. These
sensors can be mounted on the wheel chair or on person’s hand. The use of this
sensor is to constantly transmit the acceleration data to the microcontroller.
Now the proposed system keeps on monitoring the fall of the person or any
sudden movement changes. Now if the case is that the person didn’t fall and it
was just an abrupt movement with jerk, then the system allows snoozing to alert
if person presses snooze button in 5 seconds or an allotted time interval. If
the person does not press the snooze button, the system detects that the person
has fallen and automatically triggers an alert through a message to their
beloved ones about the situation instantly.
Simulation:
We have simulated the utilization of accelerometer with the
support of IBM IOT BLUEMIX SERVER- NODE RED. We have specified the link and
snapshot of the simulation in NODE RED of IBM IOT BLUEMIX server.
