Embodiment Construction

[0024] The method described in this paper has been realized in the information system of COMAC. The development of the aircraft parameter calculation model needs to be completed with the help of supporting auxiliary tools. The main development steps of the model are as follows: figure 1 Shown:

[0025] Step 1. Import the ICD file related to the aircraft parameters;

[0026] Step 2. Define the basic attribute information of the calculation model, including part number, version number and other information.

[0027] Step 3. Define the communication configuration parameters, including the source address information of the ICD message and the destination address information of the aircraft parameters.

[0028] Step 4, define aircraft parameter information, including aircraft parameter name, parameter ID, parameter type (including int32, float, String, Date, Time) information.

[0029] Step 5. Establish the association relationship between aircraft parameters and original ICD me...

Abstract

The invention belongs to the field of avionics, and puts forward a design method for an airplane parameter calculation model. The method comprises the following steps that: S1: importing an ICD (Interface Control Document) related to an airplane parameter; S2: defining the basic attribute information of the calculation model; S3: defining a communication configuration parameter; S4: defining airplane parameter information; S5: establishing an association relationship between the airplane parameter and an original ICD message; S6: checking the logicality of the association relationship, whereinthe logicality comprises the compatibility checking of the airplane parameter type and the associated ICD message type and the matching checking of the consistency of a plurality of relevant field data types in a one-to-many association relationship; S7: carrying out the integrity checking of the airplane parameter, wherein the integrity checking comprises the integrity of information and the integrity checking of an original ICD data association relationship; S8: after the integrity checking and the logicality checking are passed, generating the CRC (Cyclic Redundancy Check) codes of the configuration file; and S9: exporting an onboard loadable configuration file, and providing an airplane parameter calculation model configuration file for an onboard airplane parameter resolving program.

Description

technical field [0001] The invention belongs to the field of avionics. Background technique [0002] On-board programs such as aircraft cabin systems, electronic flight bags, and display applications usually need to convert the received raw bus data into aircraft parameters in an engineering format with specific physical meanings, so that the crew can view them and use related applications. [0003] Most of the traditional aircraft parameter calculation programs are tightly bound to specific ICDs during the implementation process, and the calculation programs lack versatility. When the ICD changes, the on-board solver needs to be modified, compiled, verified and reloaded. Contents of the invention [0004] Purpose of the invention: [0005] The invention proposes a method for defining an aircraft parameter calculation model, which separates the calculation model from the on-board calculation program, improves the versatility of the on-board application, facilitates the e...
