System Architecture
This section presents the architecture of the designed device. The
system consists of permanent magnet, reed switch sensor, embedded
controller, buzzer and relay. The function of the components are as
follows:
Permanent Magnet:
Permanent magnet is used in this work to identify whether the stand is
in horizontal position or not. Neodymium magnet is used which is kept
attached with the side stand of the motorcycle. This type of magnets are
made from an alloy of Neodymium, Iron and Boron. Hence, called as NIB or
Neo magnets.
This is the strongest commercially available permanent magnet
[13,
14]. This magnets can be used in
electrical machines as they have high energy product. The maximum energy
product (BH)max (which gives a measurement of the
produced field) for a permanent magnet can be calculated theoretically
as following [15]:
(BH)max= (4πMs)2/4 (1)
Here Ms is defined as saturation magnetization.
The magnet used in our work is circular in shape. It has a diameter of
12 mm and a height of 1 mm. The magnet is attached with the side stand
in a convenient position so that it can be detected by the reed sensor
when the stand is in the horizontal position. Whenever the stand goes to
vertical position, it will not be sensed. The magnet helps to sense the
vertical and horizontal position of the side stand in this way.
