摘要
简要介绍了车载智能仪表系统的设计思路和总体设计要求,分析了车载智能仪表系统的车速、温度、油位传感器的工作原理以及各传感器产生相关频率的脉冲信号的实现原理,详细论述了以AT89C2051单片机为核心,并辅以外围扩展电路而构成的系统智能模块对车辆进行数据采集、数据显示、风扇控制的模拟方法,并给出了系统设计中的部分硬件电路图.
The designing thought and general designing requirement of the intelligence instrument system in vehicles (IISV) and are introduced. The operation principles of velocity sensor, temperature sensor, oil sensor and the realization principle of forming the pulse signal of relevant frequency by sensor are analyzed.The simulation methods of data collection, data display, fan control by the intelligence module, which is composed of AT89C2051 and extended circuits, are discussed in detail. Some circuit diagrams of hardware in the systematic design are provided
