Hybrid Switching is a Technology through which we can switch the loads (Light,Fan,Airconditionor etc) by manually and remotely within a single setup.
The important role of this switching is to fulfil the lacks
of today’s automation trending.
Ø Basically
in Home automation technology or IoT based technology, we switch the loads by
the help of internet and the lack in this technology is if the device is not
connected through internet then the system will not work. And the use is not
friendly to all user as all the people are not sound to access technology they
need their traditional technology.
Ø Another
demerit is the IoT enabled device work with voice command which is English
enabled and all are not good to deliver the command.
Ø In
IoT enabled technology the manual mode is disabled.

Load
Power Supply
Power supply is the central part of the system. The power
supply consists of two segment online power supply and backup power supply.
Backup power supply is a battery powered source which give
backup when the online power is interrupt.
Online power supply is transformer power supply which
have a rectifier circuit, filter & voltage regulator circuit. It gives the
constant DC supply when the main supply is present & simultaneously charge
the battery backup.
Backup battery gives the supply when the online
supply is absent. It is a rechargeable battery source which is recharge when
the level of charge is low. And discharges when the online source is absent.
This setup is meant for uninterrupted power supply.
Driver
Module
Driver module consisting of Relay setup which switch the
load when the triggering signal is applied to the relay coil.
The load is connected to the NO (normally Open) terminal of
the relay and the main line connected to the common.
When the triggering pulse is applied to the Relay it
switches from NC to NO.
Triggering
Module
Triggering Module is the central part of the system this is
the gateway where the input signal is amplified and then feed to the relay
Module.
This part contains Thyristor setup which works like latch
switch. Once the Thyristor is triggered it gives the continuous flow of supply
until any interrupted is occurred. When an interrupted signal is feed to the
thyristor it resets and stops the power flow.
For occurred the process we use an alternate switching
signal, means the polarity of signal alternate. And to achieve the goal we use
a DPDT switch for manual operation and BT module for remote Operation.
Manual
Switching Module
Manual switching is the process in which we give the triggering
pulses to the triggering module by manually pressing the switch.
Basically we use the DPDT (Double Pole Double Throw) switch
which change its polarity of triggering.
Remote
Switching Module
Remote Switching is done wirelessly through Mobile phone.
when we give the trigger signal through mobile App it sends the data by
Bluetooth Channel and Arduino process the data and trigger accordingly to the
triggering module.
Bluetooth is a short range communication module but we
choose this because of multiple user facilities. Means specific authentication
is not need to connect. Anyone can connect to the module when the module is not
connecting to any user.
- We can use any wireless module for load switching remotely.
Conclusion
This is the Technology towards
Automation Mechanism. It Gives Dual mode operation of Load Switching. This is
Reliable, as it has Manual switching, so there is a backup mode if remote
switching is Failure.
In remote module I use the Bluetooth channel
because it is easy to operate, no internet is required.
