Abstract POWER CRISIS is being one of the major topics to be discussed. The possible solution for this is to provide considerable amount of power using adaptable renewable resources. Among these resources, human population is the only abundant and perennial resource that has not been utilized. If a suitable method is available, expected amount of power can be tapped out from this resource. We have presented the idea to utilize human locomotion power to produce electricity and also we have designed a method named POWER GENERATION SYSTEM, a large scale project that consists of number of similar mechanical setups under a special flooring system. When people walk over the platform, electricity is generated in this system utilizing the pressure due to weight of the person walking on the platform and stored using dry batteries. This method will have an efficient outcome if installed in countries where population is more.

1. Introduction Due to the shortage of conventional energy sources, there is necessary requirement to use nonconventional energy sources. But the best alternative is to use most of the non-conventional energy sources. While thinking about to use non-conventional energy sources, it comes in our mind that the pressure of foot step is also used to generate electricity. In our system we use pressure to produce electricity. So we implemented such a system with some mechanical assembly, we name it as power hump it consists of two springs connected with pressure bar and gear assembly. When we apply pressure, spring moves downward & when we remove pressure, spring comes to its original position. Kinetic energy is converted into electrical energy with the help of dynamo. Battery is use to store electricity to get 12V supply. Inverter will be design for single phase 230V AC supply. This generated power can be stored by using different

electrical devices. We can supply this energy to street lights, traffic lights, and nearby areas, and thus helps in country’s economy.

2. SMART BATTERY CHARGER (SBC) The smart battery charger used in our system are used to protect the battery from overcharging and fully discharging as we know that for the longer life of battery it should not be overcharge and fully discharge. So SBC consists of microcontroller, it read the battery voltage with help of ADC and display value on LCD and also used to control the voltage level of battery.

2.1 Microcontroller Microcontroller AT89C2051 is the heart of the circuit. As we know that it is a low voltage, highperformance, 8-bit microcontroller that features 2kB of Flash, 128 bytes of RAM, 15 input/output (I/O) lines, two 16 bit timers/counters, a five-vector two- level interrupt architecture, a full-duplex serial port, a precision analogue comparator, on chip oscillator and clock circuitry. A 12 MHz crystal is used for providing the basic clock frequency. All I/O pins are reset to ‘1’ as soon as RST pin goes high. Holding RST pin high for two machine cycles, while the oscillator is running, resets the device. Power on reset is derived from resistor and capacitor. Switch is used for manual reset. 2.2 Serial ADC The microcontroller monitors the battery voltage with the help of an analog to digital converter. The ADC is an 8-bit successive approximation analog to digital converter with a serial I/O and very low conversion time of typically 32µs. the differential analog voltage input allows increase of the common-mode rejection and offset in off the analog zero input voltage. In addition, the voltage reference input can be adjusted to allow encoding of any smaller analog voltage span to the full 8-bit of resolution. It is available in an 8 pin PDIP package and can be interfaced with microcontroller. 2.3 LCD (16x2) The system status and battery voltage are displayed on an LCD based on HD44780 controller. The backlight features of the LCD makes it readable even in low light conditions. The LCD is used here in 4-bit mode to save the microcontroller’s port pins. Usually the 8-bit mode of interfacing with a microcontroller requires 11 pins, but in 4-bit mode the LCD can be interfaced to the microcontroller using only 7 pins.

Fig 3.1.1 Block Diagram The block diagram of proposed system is shown above, it consists of foot step arrangement, which has rack and pinion, chain sprocket to tape of the kinetic energy through foot step as it further consists of gear drives which is connected to the other gear with help of chain and when we apply the pressure to the pressure bar it will rotate the gears. It is then connected to the PMMC dc generator which is used to convert kinetic energy into electrical energy. This generated energy is then stored in battery, which is operated by the microcontroller based smart battery charger. It will ensure that the battery will not be over charged or fully discharged. The LCD used in system display the battery voltage level. This generated energy is then apply to the street lights, garden lights or traffic lights etc.

3.2 Mechanical Arrangement

Fig 3.2.1 Mechanical Arrangement The above figure 3.2.1 shows the mechanical arrangement of proposed system. It consists pressure bar which is connected to two springs and at the center of pressure bar the reciprocating bar is connected. This reciprocating bar is then connected to the pinion, which is at middle of upper horizontal bar. Beside this pinion the upper gear is connected, which is then connected to the gear of lower horizontal bar as shown in fig. The PMMC DC generator is connected to the gear of lower horizontal bar. As we apply pressure on this pressure bar the springs moves downwards and the pinion is rotate due to reciprocating bar. As the pinion rotate the gear connected beside it is also rotate and it will rotate the lower gear through chain. Hence because of rotation of lower gear the PMMC DC generator is also rotate and convert the generated kinetic energy into electrical energy.

5. Conclusions The project “Foot Step Power Generation System With Solar Panel” is tested and implemented which is the best economical, affordable energy solution to common people. This can be used for many applications in rural areas where power is available in less quantity. As India is a developing country where the energy management is big challenge because of huge population.
