Measurement and Control System for Single-cylinder Engine Test Bench

Abstract

The invention discloses a measuring and controlling system for a single-cylinder engine testboard, which comprises an upper computer, an intelligent instrument, a PLC (programmable logic controller), a plurality of sensors and a first electric actuator, wherein the upper computer is respectively connected with the intelligent instrument and the PLC; the upper computer sets a stable judgment interval for the operational parameters of an engine and sets an alarming threshold value, and downloads online to the intelligent instrument; the intelligent instrument is respectively connected with the sensors and the first electric actuator, so as to obtain operational parameters of the engine at a monitoring point during the running process of a single cylinder engine; further the working state of the first electric actuator is adjusted, and an auxiliary system is controlled; the intelligent instrument is further connected with the PLC and used for conveying warning signals to the PLC; and the PLC gives an alarm for prompting according to the warning signals. In the invention, through the application of the intelligent instrument, discrepancies caused by multitasking and processing speed of the upper computer can be overcome, task dispersion is achieved, and the reliability and the stability of the overall system are improved.

Description

technical field [0001] The invention relates to a measurement and control system, in particular to a measurement and control system for a single-cylinder machine test bench. Background technique [0002] The development of the engine test bench began in the 1940s and 1950s. It is the main equipment for engine performance tests. Its level directly affects whether it can faithfully reflect the performance of the engine and whether it can provide the basis for engine design and improvement. In the process of engine development, development, production and use, the engine test bench link is very important for engine theory, design and manufacture of new products, research and improvement of the performance of engines and their parts, and correct guidance for production, maintenance and use. meaning. With the application and development of computer technology and electronic technology in the measurement and control system of the test bench, the modern engine test bench integrate...

AI Technical Summary

Problems solved by technology

[0006] 1. In the test and development of a single-cylinder machine, the control functions of various adjustment devices of the peripheral system are generally concentrated on the upper computer, which increases the calculation and processing burden of the upper computer, occupies a large amount of operating resources of the industrial computer, and increases the system. operational risk

[0007] 2. The objects of the single-cylinder machine are constantly changing and the types of test tasks are different. There are different requirements for the variable participation range and combination conditions of the logic control, and the configuration is not flexible.
