RF Based Toll Tax Automation

Description

This RF Based Toll-Tax Automation kit is being designed to bring the RF technology (range limited wireless communication) in use that is a widely used wireless communication system. It is used in different applications in different forms like security systems, attendance systems, wireless control units, etc. In this system, we are using this technology to make a wireless remote through which has an inbuilt unique identity and can be used to notify and define any person, object, etc.

There RF Based Toll-Tax Automation are two sections of this kit fully automatic toll tax collection; one is transmitter end and the other one is receiver end. At the transmitter end, there is an encoder IC that encodes the 4-bit data and transmits it with a wireless device working at 315/434 MHz. At the receiver end, the RF receiver receives the data with the antenna and feeds these data to the decoder IC.

The decoder IC decodes the data in 4-bit mode and the microcontroller checks the data sequence with these 4 bits. The display unit is an LCD of 16×2 sizes. RF Based Toll-Tax Automation is used for proper user interaction. The control will identify the tag thus the user and check for the account balance if the balance is available the predefined amount will be detected and the toll gate will open else not. Here we have used 4-bit tagging hence the number of users is 15. Every user will have a unique TAG (a binary sequence).
