FAULT 2 (NO MONEY REDUCTION)

OBJECTIVE

- To analyze and solve the problem happen during build this project.

FAULT 2

There have problem that the credit not reduced although the load already used, it fault from connection interfacing hardware and software between the power meter and PIC.

TROUBLESHOOTING FAULT (NO MONEY REDUCTION)

     To trace the fault, check the circuit:

i. Troubleshoot Power Meter. The connection in the right position Pulse Reading Meter  (Pin 5 and Pin 6)                         

 ii.The software (program) right because no error after compile at the C Compiler

CONCLUSION

To solve the fault is to change the program from: 

1 KW = RM0.10      TO          1 PULSE = RM 0.10

The reduction depends on the pulse of the signal from Power Meter to PIC. It happens because for 1kW, it will take a long time because 1 kW = 1000 pulse.

FAULT 1 (RESISTOR BURN)

OBJECTIVE

- To analyze and solve the problem happen during build this project.

CONTENT

FAULT 1 

There have two connections wire of the same color this had been changes between 240V and 5V input.  From the fault, resistor become burn because overload the input supply and LCD cannot display the any value.

TROUBLESHOOTING FAULT 1 (RESISTOR BURN)

To trace the fault, check the circuit:
 i. Check the PIC burn or not. The PIC it still in good condition.

ii. Check  the connection on the track layout.

It is connected and has no damage or failure of the connection on track.

iii. Troubleshoot Power Meter. It still in good condition.

CONCLUSION

To solve the fault change the new resistor, 10kΩ and Crystal 20Mhz. so the problem has been resolved and the project run smoothly.

Replace of new component (Crystal = 20MHz) 

Replace of new component (Resistor = 10kΩ ) 

RESULT REDUCTION OF MONEY

CONCLUSION

AVERAGE DURATION TIME = 4:17 min

1 KW = 1000 PULSE

1 PULSE = RM 0.10

** DEPEND ON LOAD ARE USED

RESULT AT LED DISPLAY

Result at LED Display

RESULT AT LCD DISPLAY

Result for RM 10.00

Result for RM30.00

Result for RM 2.00

CONCLUSION

     The RFID smart card has been printed with details of the credit “RM 2”,“RM 10”, “RM 30”. The results displayed at the LCD showing the value of credit and code of the smart card “b5e2f8 = RM10”,“b5e2fe = RM 2”,“b5e301 = RM 30”. The Smart Card and the data displayed at the LCD and at the smart card must same. The value of credit is referred as unique smart card from the RFID card. Unique smart card is pre-programmed card before users want to consume electricity. Smart card can be programmed with any information stored in the PIC.
