Embodiment

[0030] First, define the list of automatically pushed data that needs to be monitored in the configuration file. The content of the configuration file includes the following parts:

[0031] ■ICD information;

[0032] ■ Automatic push data list.

[0033] The automatic push data list defines the data that needs to be pushed to the ground station when the automatic push condition is satisfied, the data includes parameter name, sampling period, whether to perform automatic push, ICD message, data field, record subframe, word position, bit position Wait.

[0034] After the configuration file is generated, it can be loaded into the on-board software. When running, the on-board software will first perform initialization activities, read the configuration file, and initialize the predefined list of automatic push data. After initialization is complete, start two threads:

[0035] The first one is the data monitoring thread: this thread monitors the bus according to the ICD informa...

Abstract

The invention provides an implementation method of an automatic data pushing method in air to ground data transmission, belonging to the field of airborne maintenance. The implementation method of theautomatic data pushing method in air to ground data transmission comprises the following steps: step 1, initializing a software, loading a configuration file, starting a data monitoring thread and entering step 2; and meanwhile, starting an automatic pushing thread and entering step 5; step 2, receiving avionics data periodically by the data monitoring thread, wherein the avionics data is ignoredif the length of the received message does not conform to the length of the message defined in the configuration file; otherwise, entering step 3; step 3, parsing the data, and finding out whether the data is automatic pushing data or not according to the attribute; and if so, entering step 4; step 4, adding the data to an automatic pushing queue if the automatic pushing conditions are satisfied;and if the parsing is completed, entering the step 2; otherwise entering the step 3; step 5, detecting whether the data to be pushed is existed in the queue or not continuously by the automatic pushing thread; if so, entering step 6; and step 6, extracting the data from a list, pushing the data to the ground station, and returning to the step 5.

Description

technical field [0001] The invention belongs to the field of airborne maintenance. Background technique [0002] In today's aviation technology, flight data, especially key data (such as failure and failure data), is particularly important, and it is also very important to receive and preprocess this type of data in real time. These behaviors not only enable pilots to analyze the results in a timely, Quickly taking pretreatment measures can also enable the pilot to quickly and effectively deal with some adverse conditions according to the analysis suggestions of the ground station, so as to prevent these conditions from further accelerating deterioration, thereby improving the service life of corresponding components or equipment, and prolonging equipment Use cycle, further reduce the cost of use. [0003] The ground maintenance work after the flight of the aircraft consumes a lot of manpower, material resources and financial resources. Therefore, how to take effective meth...
