数字万用表在汽车电子器件检测与模拟中的作用

1气车电子信号的主要类型汽车的传感器、执行器的电信号可以看成控制系统中互相通讯的语言。汽车电子信号主要有直流电压信号、交流电压信号、频率调制信号、脉宽调制信号和串行数据信号等。正是这些电子信号利用各自不同的特点,实现了汽车电子控制系统中各传感器与ECU(电子控制单元),ECU与各执行器,ECU与ECU之间的不同通信的目的。

The Applications of Digital Multimeter in Automotive Electronics Testing and Simulation

Abstract：When the car fails inspection of electronic components, the important cause of the malfunction is to measure the data and reasoning process. Unlike the case of electronic components, mechanical parts inside can be opened to see, and use reasonable and logical steps that can quickly detect problems in this process is a key tool in the multimeter. Normal multimeter can test voltage, resistance, current, not suitable for modern vehicle maintenance and inspection of electronic components electronic components for the automotive repair characteristics of the current market with the multi-function digital multimeter car has many special test vehicle electrical system functions, such as frequency, duty cycle, pulse width, temperature and so on.Here are electronically controlled multi-function digital multimeter on the common electronic components, engine testing, for the majority of vehicle maintenance engineering and technical officers.
