Airplane oil monitoring device

Abstract

The invention provides an aircraft oil liquid monitoring device, which is installed on the oil circuit of important parts such as the engine, landing gear, flaperon or empennage of the aircraft; the device includes a data acquisition unit, a data processing unit, a data storage unit, a data transmission Unit and power supply unit; the data acquisition unit uses embedded oil analysis sensors to monitor the lubricating oil condition of the lubricating oil pipeline in the engine compartment or the hydraulic oil condition of the hydraulic oil pipeline of the landing gear, flaperon and empennage. The invention utilizes the combination of embedded oil analysis sensor and ZigBee wireless communication technology to realize the online real-time monitoring of aircraft oil, and can transmit the data to the terminal collector through wireless communication for processing and analysis to obtain the results, realizing the The remote monitoring of aircraft oil saves the workload of repeatedly draining oil and transporting oil, saves time, and eliminates the possibility of introducing pollution during oil draining and oil transport.

Description

technical field [0001] The invention relates to the technical field of aviation measurement and control equipment, in particular to an aircraft oil monitoring device. Background technique [0002] Aircraft oil monitoring is to use oil analysis technology to comprehensively analyze the lubricating oil and hydraulic oil used by the aircraft to obtain the lubrication and wear of the aircraft engine and the use of the hydraulic system. Oil analysis can effectively monitor the aircraft The use of key components such as engines, landing gear, flaperons and empennages, check and predict aircraft failures, and ensure aircraft safety. [0003] Oil analysis technology, also known as equipment wear condition monitoring technology, is a new type of equipment maintenance technology. It uses the equipment condition information carried by the oil to make judgments on the current and future working conditions of the equipment, thereby It provides an effective basis for the correct maintena...

Problems solved by technology

[0004] In the prior art, according to the difference and relationship between oil sample collection methods and analysis locations, machine oil analysis instruments or systems can be divided into three basic forms: 1. Off-line (off-line), on-site (on-site) , using portable oil analysis instrument) and off-site (off-site, using basic configuration or fully configured oil analysis laboratory) to analyze representative oil samples collected in periodic or non-periodic ways, and its analysis structure is easy Affected by various factors in the process of oil sample collection, transportation and experiment; 2. On-line (on-line), continuous or intermittent analysis of part of the circulating oil, has little influence on the flow state of the machine oil, and can provide direct The results are hardly affected by external factors, but if the number of samples collected is small, the online analysis results may lose representativeness; 3. Embedded (in-line) or in-situ type (in-site), continuous analysis system All the oil is circulated and the analysis results are provided immediately. The analysis process is not affected by external factors, but the analysis is difficult to implement and may affect the normal operation of the oil system
