Embodiment Construction

[0014] At present, the analog parameters of telemetry data are processed based on the subframe synchronization code. If all subframes in the whole frame are synchronized, all the analog parameters of telemetry data are considered correct. If a subframe is not synchronized, all the telemetry data of the whole frame will be deleted. When the telemetry data is received unstable, the subframe synchronization is correct but there are still a large number of jumps in the analog parameters of the telemetry data. After using the above method, there are still many jumps in the analog parameters of the telemetry data, which affects the data interpretation.

[0015] In order to solve the shortcoming that the jumping point of the telemetry data analog parameter cannot be eliminated, the present invention provides a method for removing the jumping point of the telemetry data analog parameter, including:

[0016] Step 1. Perform analog parameter processing based on the subframe synchronizati...

Abstract

The invention relates to a method for processing telemetry data and provides a method for eliminating analog parameter jump points of the telemetry data. The method comprises steps as follows: Step 1, analog parameter processing is performed according to a subframe synchronous code judgment standard; Step 2, a predicting parameter is selected from analogs of the telemetry data; Step 3, predicting parameter judgment is taken as a judgment standard, when the parameter value is beyond a predicting parameter value range, a subframe synchronous code corresponding to the moment is changed into a nonsynchronous code value; Step 4, analog parameter processing is performed according to the subframe synchronous code judgment standard again. According to the method, the predicting parameter in analog parameters of the telemetry data is taken as the judgment standard, the analog parameter jump points are eliminated, means for eliminating the jump points are increased, the number of the jump points of the telemetry data is reduced, and analysis of the telemetry data is facilitated.

Description

technical field [0001] The invention relates to a method for processing telemetry data, in particular to a method for eliminating jump points of analog parameter parameters of telemetry data in a pulse code modulation (PCM) frame format. Background technique [0002] Telemetry data is an important way to obtain the working status of the aircraft during the test process. Affected by factors such as aircraft attitude, reception quality of the ground telemetry station, and other interferences, telemetry data jumps cannot be avoided. PCM telemetry is widely used in aircraft tests. According to item 5.1.4 of GJB21.2A-92 "Telemetry Standard Multiplex Signal Format", the PCM frame format consists of subframes and subframes, and each subframe contains subframe synchronization code groups ( Such as figure 1 ), the analog parameters in the telemetry data are generally arranged in fixed channels in the frame format. In item 6.4 of GJB 2238A-2004 "Telemetry Data Processing", the telem...
