Hybrid Switching

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.

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.
