[0142] 1. Trigger event configuration

[0143] Trigger event configuration is divided into process configuration, instruction configuration and timing configuration.

[0144] 1.1 Process configuration

[0145] The process configuration is mainly to configure the process name and process number in the file.

[0146] The configuration file is as follows:

[0147]

[0148]

[0149]

[0150]

[0151] 1.2 Command Configuration

[0152] Instructions are instructions with coded files, and the codes in the files are sent directly to the aircraft.

[0153] Instruction configuration is mainly to configure the instruction name and instruction number in the file. The corresponding trigger event configuration file is as follows:

[0154]

[0155]

[0156]

[0157]

[0158] 1.3 Timing configuration

[0159] Timing is divided into zero timing and normal timing. Zero timing is triggered by monitoring the change of condition parameters. Time timing is based on the previou...

Abstract

The invention discloses a real-time interpretation method for complex parameters. The method comprises the step of: forming a plurality of criterias by combing a correct range of telemetry parametersin different states, and binding triggering event for the criterias; performing interpretation once when one frame of data is received, updating flows and the criterias according to the received dataframe in the interpretation process, and triggering update of the criteras by utilizing clock monitoring timing events simultaneously, thereby realizing whole-course real-time automatic precise interpretation, and laying a foundation of acquiring aircraft defects and health assessment in real time. According to the real-time interpretation method for complex parameters, misjudgment rate is greatlyreduced, and the precision of parameter interpretation is improved.

Description

technical field [0001] The invention relates to a real-time interpretation method of complex parameters, which belongs to the technical field of prediction and health management. Background technique [0002] Prediction and Health Management (PHM) technology is the key to realizing the autonomous support of my country's next-generation weapons and equipment. It predicts the remaining life of the product based on the historical records of the product, and detects the "health" status of the product to find signs of failure. , in order to properly repair and replace the appropriate parts at the appropriate time, so as to ensure the normal and stable operation of the system. In the United States, NASA listed it as the first of the twenty key technologies in the 21st century, and the U.S. Air Force regards PHM-based autonomous logistics support as one of the three major capabilities of fighter jets. [0003] my country's prediction and health management technology started late, a...
