| Abstract: | Based on the analysis of the radio frequency vehicles recognition system,the paper introduces the software and hardware design of signal processing module in this system.The hardware design of signal processing module is based on the low cost and high performance chip,the AT89C51 chip.The software design of it achieves some functions such as guarding against the collision, CRC, coding and decoding, correspondence.Thus,as the signal processing module, the cost is low, the recognition time is short, the ability of anti-jamming is strong,and the correspondence is reliable. |
