Portable detection diagnostic apparatus for armored equipment engine and detection method thereof

Abstract

The invention discloses a portable detection diagnostic apparatus for an armored equipment engine. The portable detection diagnostic apparatus comprises a power supply module, a digital signal processing module connected with the power supply module and used for real-time processing, calibration and parameter calculation of analog quantity, and a microcontroller module connected with the power supply module and the digital signal processing module and used for calculating and processing the analog quantity. The invention also discloses a detection method of the portable detection diagnostic apparatus for the armored equipment engine. The detection method comprises the following steps: step 1, acquiring a rotating speed signal, a vibration acceleration signal, a flow signal, a temperature signal, an air inlet pressure signal, an air inlet resistance signal, an exhaust gas pressure signal, an oil supply pressure signal, a starting current and a starting voltage; step 2, taking the rotating speed signal as a trigger, intercepting other signals in a whole period, carrying out state detection and fault diagnosis according to characteristic values or indexes of various signals, and detecting and judging faults of the engine according to various parameters of the vehicle.

Description

technical field [0001] The invention relates to the technical field of armored equipment detection, and more specifically, the invention relates to a portable engine detection and diagnosis instrument for armored equipment and a detection method thereof. Background technique [0002] With the development of science and technology, the technical complexity of armored equipment is increasing, making the task of equipment support more difficult. In the process of equipment maintenance and fault identification, it is required that the testing instrument can not only measure a certain quantity independently, but also hope that they can communicate with each other to realize resource sharing, so as to complete the comprehensive analysis and evaluation of the measured system and obtain the correct value. judge. [0003] As the power device of armored equipment, the engine's technical status has an important impact on the performance of the entire vehicle. Therefore, it is of grea...

Problems solved by technology

But these two detectors basically have common shortcomings: they are not completely suitable for data collection, analysis and fault diagnosis of 12150L series engines

Among them, the "engine tester" exists as an independent instrument, which cannot make full use of computer resources, cannot be interconnected with the computer, does not meet the requirements of network analysis, and does not have a complete fault diagnosis function
