摘要
针对飞机发动机信号数量多、附属系统越来越复杂,所要测量的参数及需要进行数据交联的设备越来越多的特点,从硬件系统设计出发,设计了以DSP+CPLD的嵌入式参数采集系统。该系统电路结构简单、集成度高、可靠性高、数据传输速度快,可用于滑油温度、滑油压力、燃油流量、发动机转速、汽缸头温度和发电机温度等数据的采集。
According to the characteristics of too many engine signals,more and more complex affiliated systems,increasing parameters needing to be measured,and increasing equipments which need data interaction,an embedded data acquisition sys-tem based on DSP＋CPLD was designed. This system has the advantages of simple circuit structure,high integration,high reli-ability and high data transmission speed. It can be used for data acquisition of lubrication oil temperature,lubrication oil pres-sure,fuel flow,engine rotational speed cylinder head temperature,engine temperature,etc.
