Problems solved by technology

[0002] With the development of test informatization, at present, each test bench of aero-engine test has adopted the information system to record the test information, and the massive test data has also been managed by the test information management platform. Faced with a large amount of test data, the engine The key information has always been obtained manually by experienced workers or technicians. Due to the influence of various factors, the accuracy of the obtained data is poor, the amount of information obtained is not enough, and the obtained information cannot accurately reflect the status of the engine.

Embodiment Construction

[0027] The invention provides a method for automatically extracting aero-engine test information, which is used for automatic extraction of key parameter data of aero-engine tests. It can automatically judge and read the key information of the engine in each state during the unsealing, cold running, false start, start-up and operation of the aero-engine test.

[0028] The data of each acquisition system is sent to the test main control system through TCP, the data is integrated through the main control system, and then the main control releases the data to each monitoring system, the information acquisition computer obtains the data released by the main control, and through the interpretation of the data , giving results of key information such as Figure 6 shown.

[0029] Such as figure 1 As shown, when the engine state is below the idle state, there is a one-to-one correspondence between the engine state and the engine control state word, such as unsealing, cold running, a...

Abstract

The invention relates to an aero-engine test information automatic extraction method with the advantage that engine key information in states of engine unsealing, cold operation, false starting and starting and in other state processes can be automatically judged and read. The method comprises a step of automatically extracting unsealing, cold operation and false starting test information and a step of automatically extracting starting test information. The invention aims at the method for obtaining the information in the aero-engine test, so that a test information system can realize efficient and correct operation, the work efficiency is improved, and the labor cost is reduced. The goals of accurate positioning, correct judging and timely fault handling are achieved on the engine judgment.

Description

technical field [0001] The invention belongs to the field of aero-engine testing, and in particular relates to a method for automatically extracting aero-engine testing information. Background technique [0002] With the development of test informatization, at present, each test bench of aero-engine test has adopted the information system to record the test information, and the massive test data has also been managed by the test information management platform. Faced with a large amount of test data, the engine The key information has always been obtained manually by experienced workers or technicians. Due to the influence of various factors, the accuracy of the obtained data is poor, the amount of information obtained is not enough, and the obtained information cannot accurately reflect the status of the engine. . How to obtain the key information of the engine through an effective and correct method is the main focus of this field. Contents of the invention [0003] (1...
