Abstract

The invention discloses a hardware-in-loop experiment platform for an electric control system of a liquefied petroleum gas engine, and the experiment platform comprises an upper computer system which is provided with a built-in liquefied petroleum gas engine simulation subsystem and a built-in communication and sensor signal reproduction collection subsystem. The liquefied petroleum gas engine simulation subsystem is used for calculating the state data of the liquefied petroleum gas engine under various working conditions. The communication and sensor signal reproduction collection subsystem is used for receiving calculation data, converting the calculation data into a sensor signal, transmitting the sensor signal to a liquefied petroleum gas engine electric control system, and collecting, transmitting, displaying and storing related signals. The experiment table can achieve various types of testing of the liquefied petroleum gas engine electric control system, solves problems of high danger coefficient, high cost, long period and poor repeatability in a development process of the liquefied petroleum gas engine electric control system during installation testing through a real machine, and provides a reliable test platform for the control strategy research and the algorithm design and verification of the liquefied petroleum gas engine electric control system.

Description

technical field [0001] The invention relates to a hardware-in-the-loop experiment platform, in particular to a hardware-in-the-loop experiment platform for an electric control system of a liquefied petroleum gas engine. [0002] technical background [0003] The liquefied petroleum gas engine has excellent performance such as low emission and pollution, and has become one of the most popular new energy engines at present. The excellent performance of the LPG engine depends on the characteristics of the LPG fuel itself on the one hand, and benefits from the precise control of the LPG engine electronic control system on the other hand. However, the development of the traditional LPG engine electronic control system involves the development of machinery, electronics, software and hardware, and the test is usually an actual machine installation test. Due to the poor controllability and repeatability of the test conditions, it consumes a lot of manpower and material resources. Mo...
