| 摘 要： | 转速是摩托车电喷系统点火和喷油所依据的重要参数之一,转速测量是电喷系统的关键技术。比较器调理电路和555芯片调理电路经过实际调试均能正常工作,但从可靠性和抗干扰角度考虑,555芯片组成的施密特触发器要比比较器电路可靠性高,抗干扰能力强。文中介绍的单片机测量计算转速的2种方案,实践证明准确可行。

| Abstract: | Rotational speed is one of important parameters upon which the motorcycle EFI system (ignition and fuel injection) works. Rotational speed measurement is the key technique to EFI system. The processing circuits of the comparator and 555 chip can work normally after tuning-up, but out of consideration for the reliability and anti-interference angle the Schmit trigger composed of 555 chip is better than the comparator circuit in term of reliability and anti-interference ability. The two ways of calculating the rotational speed mentioned in the paper prove to be correct and practical. |
