Abstract

The invention relates to an on-line monitoring system and method of engine test data. The on-line monitoring system of the engine test data comprises a data acquisition system and a data display system, wherein the data acquisition system comprises a clock control unit, a data acquisition unit, a data display unit and a data storage unit, the clock control unit is used for providing a time criterion for the data acquisition unit, the data display unit and the data storage unit, the data acquisition unit is used for acquiring the test data of an engine and sending the test data to the data display unit and the data storage unit in real time, the data display unit is used for displaying the received test data in real time, the data display system comprises a data analyzing unit, a curve plotting unit and a display unit, and the data storage unit is used for storing the received test data in real time and transmitting the received test data to the data analyzing unit. The on-line monitoring system and method of the engine test data have the advantages that the problem that errors exist in plotting of an existing engine test curve is solved, real-time plotting of the engine test data curve is achieved, and the engine curve can be accurately plotted in real time.

Description

technical field [0001] The invention relates to an online monitoring system for engine test data, an online monitoring system and a method. Background technique [0002] The engine test is to evaluate the state of the test system and the performance of the engine by processing and analyzing the test data. During the engine test, a real-time display system is required, and real-time curve drawing of four key parameters is required. Therefore, it is necessary to realize the real-time curve drawing of the measured data of these four key parameters and the deviation of the preset standard theoretical curve, but none of the technologies in the prior art can solve the deviation. Contents of the invention [0003] In order to solve the technical problem of deviation in the drawing of existing engine test curves, the present invention provides an engine test data online monitoring system and method, which can realize real-time drawing of engine test data curves, and can accuratel...
