摘　　要：为了实现城市专用车辆实时监控和调度,针对专用车辆运行特点,设计并实现了一种基于VHF无线通信和TDMA时分多址接入技术的移动目标实时监控系统;采用ARM微处理器S3C44B0X和μC/OS-Ⅱ嵌入式实时操作系统,设计了一种专用多串口无线通信控制器,并针对VHF无线通信保密性差的特点,提出了一种新的无线通信加密算法,即基于GPS的实时循环移位加密算法(RRSE),此加密算法即时有效,具有很高的防破解和防干扰性能。In order to satisfy the demand of urban special vehicles real-time monitoring and scheduling, in view of operating features of special vehicles, a real-time mobile target monitoring system based on VHF wireless communication and TDMA multi-access technology is designed and implemented. A kind of special multi-serial port wireless communication controller is designed based on the 32-bit ARM micro- processor S3C44BOX and the embedded real-time operating system uC/OS-II. A new wireless communication encryption algorithm named RRSE （Real-time Ring Shift Encipher） based on GPS is designed for solving the bad confidentiality of VHF wireless communication, and this algorithm is timely and effective, has quite high anti -crack and anti interference performance.
