Problems solved by technology

[0002] There are more and more avionics equipment equipped with aircraft, and they are becoming more and more complex. At the same time, it is necessary to carry out fault diagnosis on many avionics devices. Although there are many methods and products for fault diagnosis of avionics devices, they are generally universal. Poor, difficult to transplant and other issues
Especially in the development process of avionics equipment, a large number of fault diagnosis models are immature, and there are even many errors

Embodiment Construction

[0019] The present invention specifically adopts the following steps to realize the fault diagnosis of avionics equipment. Now, the fault diagnosis of the present invention is described in further detail with examples, accompanying drawings and attached tables. Please refer to figure 2 and Table 1.

[0020] First assume that the trigger conditions of fault model 1 and fault model 2 are as follows:

[0021] Failure Model 1: When , report that avionics 1 fails;

[0022] Failure Model 2: When , report avionics 1 failure.

[0023] Step 1: The parameter preprocessing module preprocesses N 1 , N 2 The three parameters of T and T are converted into engineering values ​​that can participate in calculations.

[0024] Step 2: The diagnostic logic can be loaded into the fault library to input avionics 1 failure, fault code X1; avionics 1 fault, fault code X2 (other fault information is simplified and not involved in this example). And define the failure trigger judgment value o...

Abstract

The present invention belongs to the avionics field, and especially relates to a fault diagnosis method based on an avionics device. Although there are many method and products for fault diagnosis ofan avionics device in the prior art, the universality is generally poor and the transplantation is generally hard. The fault diagnosis method provided by the invention employs a parameter preprocessing module, a fault database, a fault diagnosis rule base, a fault diagnosis function module, a fault report module and a loadable diagnosis logic. The fault diagnosis method based on the avionics device can rapidly change the fault database, a fault model and the like according to changing demands of a fault diagnosis system so that rapid fault diagnosis and verification of types of faults of the avionics device can be achieved.

Description

technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to a fault diagnosis method based on avionics equipment. Background technique [0002] There are more and more avionics equipment equipped with aircraft, and they are becoming more and more complex. At the same time, it is necessary to carry out fault diagnosis on many avionics devices. Although there are many methods and products for fault diagnosis of avionics devices, they are generally universal. Poor, difficult to transplant and other issues. Especially in the development process of avionics equipment, a large number of fault diagnosis models are immature, and even have many errors. In the development process of avionics equipment and fault diagnosis system, it is necessary to fully verify and test the fault diagnosis system and fault diagnosis model. Fault diagnosis system for rapid diagnosis of avionics equipment. Contents of the invention [0003] The techn...
