GPS is good in analysis of vehicle location tracking [6].To knows about the details of vehicle in which latitude and
longitude vehicle move through GIS software. The GPS is connected to the PIC microcontroller with the help of 2
(SN74HC00) QUADRUPLE 2-INPUT POSITIVE-NAND GATES IC .The 74HC00 devices contain four independent
2-input NAND gates. The 74HC00 perform the Boolean function Y = (A • B) or Y = A + B in positive logic. The
operating voltage frequency is 2V to 6V.The GSM RX is directly connected to TX of PIC microcontroller. In GSM
TX is connected with 1A of NAND gate. The1B of NAND gate is connected to controller port pin .TheGPS TX is
connected with 2A of NAND gate and 2B is connected with controller port pin. RFID reader is used to interrogate
an RFID tag. The reader has an antenna that emits radio waves; the tag responds by sending back its data. RFID tag is
placed in each goods. Each RFID tag has unique id. RFID communicates with TX and Rx. The TX is connected to 3A
and 3B is connected to any one of the port pin of microcontroller. 3Y is connected with 4A and 4B of NAND gate. 4Y
is connected to IC2 SN74CH00 of 1A and 1Y of previous IC1 SN74CH00 is connected with 1Yi and Yi is connected
with RXD pin of PIC.
