PROJECT: Home /office/industry electrical appliances controlling by phone call and confirmation through voice feedback
The world is dominated by technology and has a lot of technology today, especially in the electronics industry, resulting in a more comfortable life, friendship and luxury with consumers at low cost. In this project, we will manage the electrical equipment from anywhere in the world that uses our mobile phones, and the system also provides the voice to whether they can technically be turned on or off. PROCORP Technologies has distinct number of Electrical project list for embedded systems and develop codes fro different types of controllers.
The project will be implemented based on Advanced ARM7 LPC2148 Microcontroller DTMF technology.
Dual-frequency signal (DTMF) is used to transmit telecommunication signals over an analogue line in a band of frequency between the mobile phone and other interconnected devices and the center of the switch. The DTMF version is used in a push-button phone for voice recognition known as AT & T, which is used for the first time in trade as a registered trademark.
The DTMF-decoder is coupled to the microcontroller section. If the user wants to control all of the devices he has to dial the predefined number from your mobile phone. All of the managed devices will be attached to the control section. Each device is assigned with a unique predefined number. This microcontroller, in turn, plays a voice message about the status of the device and the voicemail will be heard via this mobile phone, as the user may receive a confirmation of this device. To play the voice sound, we do not need separate sound modules, so we can play the ARM7 LPC2148 microcontroller with directly keeping pre-recorded voice messages to memory micro controller as a binary file.
Triac is used for control of AC storage and AC uses for MOC3021 to handle the triac. The embedded C language was used to write the code in the KIEL compiler and the hex file was dumped into the controller via the flash magic software.
