Design of vehicle transponder based on single chip microcomputer
Abstract: With the promotion of our country's economic globalization, the economy of different regions communicate a lot, and the high-speed railway enjoys a rapid development. Railway communicating system is the key part of guarantying efficiency and security. Balise is the key component of ATP which is being used to realize the data transfer between different high-way stations and to provide various information points for the trains to ensure the safety of train running at a high speed. This topic is to design a microcontroller-based automotive balise. The wireless device I have chosen is point-to-point way which can realize the stimulation through the signal emission from the transmitter and signal receiving form antenna receiver. Transmit the chip through microcontroller PIC16F690 and wireless transceiver CC1100 which consists of a simple transceiver system. Export the data from the computer, and then process the signal through the microcontroller PIC16F690, next transmit the signal to the receiving end via the antenna through the chip CC1100, and then process the action and feedback to realize the whole process and to achieve the stimulation of working as vehicle balise.
