Long distance diagnosis real time tracking system and method thereof

Abstract

The invention refers to a flight remote-diagnosis real-time tracking system, including AC ARS message ground receiving terminal, ACARS message decoder, middle server and database server saving the decoded ACARS message and the electronic document of airplane failure code, and the user terminal receiving the user instruction, displaying the decoded message and making failure alarm. It can rapidly and real-timely finished the works of failure alarm, analysis and judgment on the failure by engineers, establishment of the project to eliminate the failure and so on through the computer, providing active condition to eliminating emergent failure.

Description

technical field [0001] The invention relates to a remote diagnosis system, in particular to an aircraft remote diagnosis real-time tracking system and its method for real-time monitoring of aircraft and engine operating states, timely detection of faults or hidden dangers and warning of faults. Background technique [0002] The flight safety of an aircraft not only depends on the correct operation of the pilot, but more importantly, depends on the daily maintenance and repair work of the aircraft. In the traditional maintenance work, we have to wait until the plane lands to know the technical condition or failure history of the plane by checking the flight log book, checking the onboard maintenance terminal or decoding the data of the flight data recorder or listening to the crew’s oral report.

Problems solved by technology

In the traditional maintenance work, we have to wait until the plane lands to know the technical condition or failure history of the plane by checking the flight log book, checking the onboard maintenance terminal or decoding the data of the flight data recorder or listening to the crew’s oral report. It is to continue to use the process of post-event diagnosis→planning→implement troubleshooting, and when the aircraft is performing a flight at an outstation, the crew has an emergency that cannot be ruled out. The only way to ask for help from the remote crew is by telephone or fax. The difference between the verbal failure description of the crew and the understanding of the maintenance personnel caused additional difficulties for troubleshooting

The disadvantages of traditional maintenance are: (1) The ground maintenance personnel and other relevant departments cannot obtain the real-time fault information of the aircraft in time, resulting in the inability to control the occurrence of flight accidents in time

(2) Because the aircraft technical status and failure information obtained by the ground maintenance personnel is not timely and comprehensive, and also limited by the level and experience of the maintenance personnel, sometimes the troubleshooting plan is not accurate enough and it is difficult to detect potential safety hazards early. Difficult to improve maintenance quality and level

(3) Maintenance costs remain high. Practice has proved that a large amount of maintenance costs come from non-routine work in the process of aircraft maintenance. In a usual routine inspection, the non-routine work is as high as 40% of the overall maintenance volume

[0003] Because of its suddenness, it is often impossible to arrange the work plan in advance, which is in conflict with the requirement to complete the maintenance work in a short time. The traditional maintenance method cannot control the non-routine workload because it cannot understand the status of the aircraft in advance. It often leads to an increase in the cost of ordering aviation materials, and even causes the aircraft to be parked due to lack of parts, increasing the maintenance cost of the airline

(4) Inaccurate judgment of aircraft failure will increase work intensity, prolong maintenance time, and easily cause delays in flight departure time

(5) Due to the above-mentioned defects, airlines cannot avoid flight delays caused by maintenance, which creates great obstacles for airlines to further improve service quality and level

Although the emergence of ACARS has improved the status of information sources for traditional aircraft maintenance, because the information it transmits is a computer language, it is generally difficult for non-computer professionals to understand it, which makes the application of ACARS information difficult. It is very limited. It needs to be translated by computer technicians first, and then manually processed by the maintenance personnel. This not only has the problem of deviation in the understanding of different professional and technical personnel, but also has the limitation of the level and experience of the maintenance personnel and the gap between the front and rear links. The connection problem makes it difficult to warn of flight failures in a timely and accurate manner. Therefore, the current ACARS information is only transmitted to the ACARS message receiving workstation of the airline company, and has not been widely used.
