Embodiment 1

[0028] In the present application embodiment, the standardized general state monitoring model architecture constitutive elements include:

[0029] Monitor events and applicable flight stages, collecting parameters, timing, data storage mode, output format, and sending methods.

[0030] Monitoring model description definition includes the following six aspects

[0031] 1. Monitor events and applicable flight stages:

[0032] The monitoring event represents the exception event logic that triggers parameter acquisition, which is a Boolean expression consisting of parameter values, constants, operators, mathematical functions, etc., which may be a specific parameter value exceeding a threshold, or a plurality of parameter values. Or multiple exceeding the threshold, or it can be received from the acquisition request instruction from the maintenance person; the applicable flight phase indicates that the monitoring criterion is only valid in a particular one or more flight phases.

Embodiment 2

[0066] According to the state monitoring model of performance degradation and functional degradation of the equipment provided herein, specific embodiments include:

[0067] Step 1: Determine the normalized generic state monitoring model architecture composition element includes: monitoring events and applicable flight phases, acquisition parameters set, timing, data storage, output format, and sending methods.

[0068] Step 2: Define the monitoring event and the applicable flight phase: Define the Boolean expression composed of parameter values, constants, operators, etc., define that the monitoring condition is valid at a particular one or more flight phases.

[0069] Step 3: Define the collection of the collected parameters: Parameters in the parameter set can come from the current device, or devices associated with the current device.

[0070] Step 4: Definition of the timing of the acquisition parameters: The timing of the acquisition can be a period of time, triggering time,...

Abstract

The invention provides a method for establishing an airborne equipment state monitoring model, and the method comprises the steps: judging whether a parameter collection opportunity is reached or notwhen a monitoring event happens and a current flight stage is valid; if the parameter collection opportunity is reached, collecting a to-be-recorded parameter set, the monitoring event representing abnormal event logic for triggering parameter collection, and the flight stage being effective in preset N flight stages; storing the acquired parameter set according to a preset storage mode; displaying the collected parameter sets on different output devices according to a preset output format; and sending the acquired parameter set to a destination according to a preset automatic sending or manual sending mode.

Description

Technical field [0001] The present invention belongs to the field of aircraft state monitoring technology, which relates to a method of establishing a status monitoring model of airborne equipment. Background technique [0002] In the operation of the aircraft, to master the functional status and performance indicators of the airborne equipment, the device data is required, and the ground is analyzed to determine whether the functionality and performance of the device meet safety needs. When collecting equipment data, it is necessary to establish a standardized state monitoring model architecture for numerous airborne equipment, and each device develops monitoring models in accordance with the model architecture, and loaded into the airborne status monitoring software. In flight, the airborne state monitoring software can be collected and recorded according to the model defined by the device. [0003] However, the airborne equipment has a wide variety of state abnormal events, th...
