摘要
为加强车载设备的集中监控和管理,设计了一种车载智能监控系统,系统采用ARM处理器和和嵌入式操作系统,具有网络化的通讯管理功能。装载平台设备均采用了串行口通讯方式,设计了一种由FPGA控制的多串口扩展板。FPGA通过和ARM的交互可以控制8个RS232和4个RS485串行口的数据收发,还可以设置各个串行口的波特率等参数。接口板具有进一步的串口拓展功能。本方案系统软件设计方便适应性强,系统工作稳定可靠,实时性好,能满足监控系统的要求。
To tighten the monitoring and management of these vehicle equipments,this paper designs a vehicle mounted intelligent monitoring system.the ARM processor and embedded operating systems are used in this system.It is of the network communication management function.Because of using serial port communicati on for these loading platform devices,a serial port expansion board contr olled by FPGA is designed.The data communication of eight RS232 and four RS485 serial ports can be controlled through interaction with ARM by FPGA and the baud rate for each serial port can also be set.The further serial expanding functions exist in the interface board.This design can strengthen the adaptability of the system software and make the system reliable and real-time.It meets the requirements of the monitoring system.
