基于LabVIEW对发动机废气余热式烟雾机的研究

LabVIEW Based on the Engine Exhaust Fogger Machine of Heat

研究了发动机废气余热发烟的原理,设计了一种利用发动机废气余热的发烟装置,并对其主要设计参数进行了理论推导、计算、分析,从而获得了发动机废气余热运算模型,建立了根据发动机废气余热量,控制喷射药剂的最佳喷药量方程。设计运用LabVIEW作为虚拟设计平台,采用模块化设计、图形化编程的方法,设计了根据发动机废气余热量控制药剂喷射量的电子控制系统,进行主控系统的仿真设计。

This article discusses the fogger of the engine exhaust heat principle, design a way to use the engine exhaust heat of the fogger device, and its main design parameters of the theoretical derivation, calculation, analysis, and thus obtain a model of the engine exhaust heat recovery operations, the establishment of more than the heat of the engine exhaust to control the amount of jet spraying pharmacy best equa- tion. Designed to use LabVIEW as a virtual design platform, modular design, graphical programming approach, designed under the control of the engine exhaust heat more than the amount of pharmaceutical injection electronic control system, main control system simulation for de- sign.
