Project Progress

My project requires switch that will turn on and off the appliances. In order to turn on and off the appliances, the appliances need to have their own frequency.

On Jan,4th 2011, I have got my Power Line Communication modem at Industrial laboratory which provide the modem trainer. The trainer consists of modem that able to accomplish my project soon. The transmitter of the modem have viewed as below :-

FE 03 3F 3F FD
FC 03 3C 07 C6

Meanwhile, the receiver of the modem have viewed as below :-

FE 03 5C 01 A0 ; one device transmitter end to
FE 03 40 01 BC ; one device is status fail

The transmitter and receiver viewed the details of the operation of the trainer after the button start have pushed to turn on. It gives the output of the appliances operation such as fan and light. The picture below is the basic diagram of modem connection with the switch and trainer.

Power Line Communication Modem

Just got the power line communication modem from Electronic Laboratory. The pictures are as below:-

Once the modem is available, I will be able to proceed with the study of modem operation and configuration by using Hi-Any Home 1000 user's manual.

PSM 1 Presentation

The PSM 1 presentation was held on 26th of November 2010. Every final year student need to present their project proposal in order to proceed their projects..

Basic Running Light Coding

//running light

#include <16f877a.h>
#use delay(clock = 20000000)
#fuses hs,noprotect,nowdt,nolvp

#byte PORTB=6
#byte PORTC=7

main()
{
   set_tris_b(0);
   set_tris_c(0x01);

      if (portc==0)
      {
         portb=0b01010101;
         delay_ms(1000);
         portb=0b10101010;
         delay_ms(2000);
      }
      else

Summary of the Literature Review

 Power Line Communication technology able to control all the home appliances through domestic power line socket. From the IEEE Xplore journals that act as a reference, I am able to add extra information in my final year project. Power Line Communication is used to utilize a domestic power line as a communication cable. The PLC provides high bit-rate data services by using the power grid residing in the vast infrastructure already in place for power distribution, which means that the potential effect of the service could be much higher than that of any other wire line alternative. PLC also easily installed in an existing residence.

Other than that, my project also will be added by PPCOM which is PLC Power-Controlled Outlet Module, the embedded home server and the remote control. It is just easy way by only plug in the home appliances to the PPCOM socket and automatically control without making any additional setting. PPCOM is able to combine multiple AC power sockets. 

In addition, I also would like to use Solid State Relays (SSR) to switch each socket on or off for an electric home appliance. SSR is able to replace mechanical relays because of their many advantages such as miniaturized configuration, elimination of contact bounce, low-energy power consumption, decreased electrical noise and compatibility with digital circuit and high speed switching performance. 

        

Other than that, if needed, I would like to develop a HAT (Home Appliance Translator) to enable conventional appliances without telecommunication capabilities to connect home networks. Users can remotely monitor and control conventional appliances by using HAT and HAT Subs. It is more easily and cheaply without information appliances, new communication infrastructures or complex setting. The HAT will communicate to the PLC that utilizes power lines as the communication medium.
