The main objective of this project is to save electrical energy up to 30% by using real time management based on embedded systems. The project based on MCS 51 series Micro-Controller (89C52), Real Time Clock (DS1302), EEPROM to control ‘N’ no. of electrical appliances according to time schedule program in the EEPROM. Here we have used 16 x 2 dot matrix LCD display to display the present time and date. The front panel keyboard is used to set time / date and schedule programming. Each module can be programmed for 10 ON / OFF intervals at any specified time to ON / OFF state, for the practical purpose we have established 4 channels / outlets each 10 intervals (ON/OFF). The program is written in micro controller for reading, writing, displaying time and date from RTC, EEPROM. The internal RTC continues to run during power fail cases with help of 3.6v Ni-Cd rechargeable battery.
We have established a synchronous serial communication to read / write data from EEPROM and RTC. The extension port is available to extend no. of devices. The program schedule can be programmed according to week / date.
The energy can be saved by applying sufficient energy to the equipments at a specified time for each and every equipment. The assembly program written in Micro-Controller for both modes i.e. time based management & Voltage based management. There is a mode switch decides weather the system is there in either time mode or voltage mode.
Initially we have to enter the schedule as per requirement through front panel key pad by the user. The programmed schedule is stored in EEPROM in the programming mode. During the normal operation the Micro-Controller reads the data from EEPROM subsequently stores the data in the internal RAM. The IIC Protocol is established between RTC and Micro-Controller for reading & writing operations. Subsequently the controller compares the time with the pre loaded schedule. According to that it operates different devices at specified time & voltages.
