Bench measurement and control equipment, measurement and control system and method for engine

Abstract

The invention discloses a jack horse measuring and controlling device for an engine, as well as a measuring and controlling system and method for engine jack horse test. The jack horse measuring and controlling device comprises a signal analyzer and an information confirmer, wherein the signal analyzer is arranged for analyzing a received state signal of the engine in order to acquire state data contained in the state signal, and the information confirmer is arranged for confirming the state information shown to a user on the basis of a preset knowledge base and the state data. In a further implementing manner, an engine-focused processing prompt message shown to the user is generated on the basis of the state information and / or a control signal for controlling the engine is generated on the basis of the state information. By using the device, the system and the method provided by the invention, friendly and lucid state information can be supplied to the user and prompt also can be supplied to the following processing, thereby increasing the efficiency of jack horse test.

Description

technical field [0001] The invention relates to the field of engine research and development, and more particularly relates to a bench measurement and control device for the engine and a measurement and control system and method for the engine bench test. Background technique [0002] With the development of engine combustion control technology, the research and development of engines has gradually shifted to the research and development of electronically controlled engines. During the development of an engine, various tests are usually carried out on the engine. The engine bench test is one of the most important of these tests. Usually, when conducting a test, the engine needs to be installed on a special engine test stand, and the engine is driven to run a dynamometer for torque, speed, and power detection. During the test, the performance and reliability of the engine under various working conditions are determined by changing the load of the dynamometer. Through the e...

AI Technical Summary

Problems solved by technology

However, fault diagnosis requires special equipment and technology, and also requires testers to have strong professional knowledge

However, the data information provided to users on the current bench equipment is extremely abstract, and ordinary technicians cannot understand it at all. Therefore, when problems arise, the test engineer can only go to the site and make judgments based on his own professional knowledge and experience.

This significantly affects the efficiency of engine testing
