Dtmf Based Water Controller Essay Example for Free

Dtmf Based urine ascendence EssayAlong with these problems there is no facility for protection from unauthorized user price of admission to the system shimmy. Why use Intelligent Water Pump? 1)Manual switching is not beneficial in if user is far away from switching station. 2)Timer found switching circuits are beneficial if duration of hitch operation is fixed. merely most of the cases it is not fixed. 3)General remote switching facility provides the efficient solution for these problem. But it is to a fault affected with the parameter range of operation. Intelligent Water Pump provides the exact solution for these problems. It uses the experience of microcontroller on with the powerful peripherals. It uses GSM intercommunicate which is now a days available in most of the places. It also provides password protection facility to protect the system from unauthorized use. It not on provides the remote switching of the system but also provides the status of system electri cal energy to the user. The system provides instant access along with uncommon voice interaction facility. Operation . GSM network- GSM stands for Global System for lively Communication It provides the network service for communication to both user controller side fluid phone. 2. User side brisk phone- User sends the accessing commands to the Pump control unit using his mobile phone. Users mobile phone also plays the received voice feedback messages from Pump control system. 3. Controller side mobile phone- Controller use this mobile phone to detect presence of call users commands( in the form of DTMF com wanderer code) from headset output. in any case voice feedback messages are put on the Mic i/p of this mobile. 4. Ring detector- When user get ahead the call , at that time the presence of ring on receiver mobile phone is detected by this circuit to inform the controller that user wants to access the system. 5. DTMF decoder- When user enters the picking,the decoder IC8870 decodes the choice equivalent binary no. are available on its o/p(Q1 to Q4). Whenever new code comes ,the DTMF decoder will pulse low (STB pin) informing microcontroller that codes are available please take them. 5. words circuit-All the voice messages required to inform the user about controlling action are stored in the voice rom(IC APR 9600). As per the trigger and control i/p from microcontroller, speech circuit put several(prenominal) voice message on the mic i/p of controller side mobile phone. 6. Controller- Microcontroller(89S52) keeps co-ordination among all peripherals. Whenever call is detected it takes controlling action according to users choice and plays respective voice messages for users acknowledgment. It also provides controlling signal for switching circuit as per electricity status user choice. . Switching tour of duty - It is basically a causal agentr circuit which provides the making and pause of ac mains to the water pump as per signal from controller . It consist of electromechanical relay and relay driver(IC2803) to drive it. 8. Water Pump- Water Pump is a load which is to be controlled by intelligence of microcontroller based system. 9. AC mains detector- This block detects the presence of AC mains. Controller check the status of this block onwards providing ON switching signal to the Water pump.Also availability of electricity can be judged from this block. 10. agent Supply- It provides necessary power to system components as per requirement for their operation. It provides the regulated power supply along with Battery Backup facility.
