Aircraft engine detection device

Abstract

An aircraft engine detection device relates to the technical field of electronic measurement and consists of a sensor 1, a signal conditioner 2, a data acquisition card 3 and an industrial personnel computer 4, wherein the industrial personnel computer 4 comprises a data recovery device 5 and a computer 6; the sensor 1 is connected with parameter points required to be measured by an aircraft engine; the signal conditioner 2 is connected with the sensor 1 to condition a signal to be in a state capable of being acquired by the data acquisition card 3; the data acquisition card 3 transmits the acquired data to the data recovery device 5 for recovery; and the computer 6 of the industrial personnel computer 4 calculates the detection result of ground driving of the engine according to corresponding formulas. The aircraft engine detection device is high in test accuracy, strong in expansibility and intensive in monitor and observation points, the data can be automatically recorded, the errors resulting from the observation of personnel are reduced, monitor parameters at various points are guaranteed to be recorded synchronously, the monitor accuracy is improved, the number of monitor personnel is greatly reduced, the safety production is facilitated, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to an intelligent detection device for ground driving parameters suitable for multi-model jet aircraft. Background technique [0002] In the prior art, a semi-mechanical monitoring platform is used to detect the ground driving parameters of jet aircraft, including mechanical pressure gauges, indicator lights, test hoses, speed indicators, signal lines, test hoses and pipelines of the engine Connection, the mechanical pressure gauge is installed on the test hose, one end of the signal line group is connected to the aircraft engine, and the other end is respectively connected to the indicator light and the tachometer. After the corresponding speed, the indicator light corresponding to the speed is on, the tachometer indicates the current engine speed, and the mechanical pressure gauge on the test hose measures the engine pipeline pressure at the corresponding speed.

Problems solved by technology

The existing aircraft engine detection device has few monitoring parameters, poor scalability, and low test accuracy, which is not suitable for the measurement requirements of various parameters of the new aircraft; the monitoring points are scattered, requiring more than 10 monitoring personnel, which is not conducive to the safety of the production site; the data adopts manual observation Pen and paper records have large observation errors, and the recorded data does not have complete time synchronization; testers are required to sort out and calculate the test data and perform secondary processing. Different models have different algorithms, and the calculation results do not meet the indicators. It needs to be re-started and adjusted, which is a serious waste of manpower and material resources, which is not conducive to modern production and testing
