摘　　要：本文介绍了基于CDMA的停车场车位引导系统的设计方案,阐述了系统软硬件设计、CDMA主要特点及接口电路图。该系统采用CDMA无线通信模块,使系统性能更加完善。实验结果表明本系统与485通信系统、CAN总线通信系统相比,通信距离和通信速率明显提高。本系统避免了一路出错导致整个系统瘫痪的问题,使停车场车位引导系统更加智能化。A Parking Guidance System based on CDMA is introduced in this paper. The software and hardware of the system , the main features of CDMA, and the interface circuit of CDMA are described. The CDMA wireless communication module is adopted in this system,which makes the system performance more perfect. Experimental results show that the communication distance and communication speed of this system are obviously more advanced than either the 485 communication system or the CAN bus communication system. The system not only avoids that one circuit error leads to the paralysis of the entire system, but also makes the guidance system of parking spaces more intelligent.
