Abstract:

The detection mode and specific communication protocol between the master part and extension part in-vehicle are presented according to the design of the system.The master part controls ultrasonic transmitter to send out continually the checking number and makes the vehicles queue orderly,therefor solves the“anti-collision”problem of many vehicles.Then the master part aims at the vehicle that has the fixed serial number to verify vehicle inherent information,with short distance radio frequency transceiver for data transmission,then identifies and detects the vehicles.The method is hardly influenced by environment and can identify the vehicle information correctly.

Key words: detection;communication protocol;anti-collision
