1- Introduction
Many situations require wireless control of the electric circuits such as the following:
· To run a water pump (on or off) in a distance farm.
· To switch –off air conditioning after leaving the home to the work.
· To switch –on air conditioning when return back to the home.
· To switch –on air conditioning in a Mosque (masjed) before the prayer time.
· To switch –off the electricity in case of fire and the electricity source control could not be reached safely.
For all the above application, this work is a trial to introduce a solution to control the electrical circuit through a mobile phone call.
Conventionally, wireless-controlled circuits use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone for circuit control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls. The control of circuits involves two distinct phases: reception, and action. Generally, the preceptors are sensors mounted on the circuit control switch, and the task (action) is performed using motors or with some other actuators.
2- Material and methodology
1. Magnetic Switch
Electro-magnetic key
Definition: is the key to the impact of electro-magnetic magnet works on electricity
Use:
- Connect the electric motor trend
Combination:
1 - mobile terminals
2 - fixed terminals
3 - Yai Returns
4 - File
5 portfolio
How it works:
When connecting the power department either AC or DC for a way file occurs in the iron core magnet attracting leading to the clipboard to the heart, leading to expansion and high Elá mobile terminals and fixed adhesion fingertips conductivity which leads to connect the circuit .
*** Relay (CutOut)***
The relay or (Cut out) is absolutely electric current, and all that is conducting e function called name, and most definitive trend in car system electrophoresis is the circuit breaker located between the generator in the car and the battery, and function of cutting off the reverse, a trend which is trying to pass battery files to the generator and lead to burn these files, and this happens the reverse flow in the case of low output generator voltage battery in the event that began on or reduced engine speed, and there are types of this firm or Alktaaot, starting from the device electromechanical it consists of a relay and points of contact, to fuse works electronically, and in the generator voltage variable modern (Alternator) a group LED (Diodes) the work of cutting off the reverse is also the organization of the severity of the current self, and keep the need only to an organized effort to maintain the effort appropriate to the load so as not to be affected by an increase of output generated when high speeds, and the fuse s no secret to you that function to protect the circuit when increasing the intensity of the current excessive and when a short (short) in the circuit .
Classification and function of relays
A protection relay is a device that senses any change in the signal which it is receiving, usually from a current and/or voltage source. If the magnitude of the incoming signal is outside a preset range, the relay will operate, generally to close or open electrical contacts to initiate some further operation, for example the tripping of a circuit breaker.
A mobile device normally used to give the relay signal to turn on or turn off electricity.
4 - Electric wires and light bulbs
Electric wires to connect the bases bulbs with each other and connected with the magnetic switch .
The idea of Relay (CutOut and Magnetic Switch with mobile
The first step is to open the mobile device and remove sensitive to vibration, then we connect the two wires the location of the vibrator, and then pass on the two wires with Relay , the relay to give an electrical signal (resulting from the mobile phone battery). When you receive relay electrical signal from a mobile transformation into a magnetic switch for connect of electricity. The same idea can shut down electricity using another mobile phone and other Relay , and is connected with the other party to the magnetic switch .
How does the project
When you call to your operator number (054373****), will reach a magnetic signal to the key and is connected to electricity.
How do we stop the project work
When you call to the shut down your number (053632****), will reach a magnetic signal to the key, and separates the power
Cord of an electric circuit.
The conclusion
Our project is not limited to anything specific and we can be applied to anything to do with electricity.
