Embodiment Construction

[0020] figure 1 For the flow chart of the method for analyzing the IRIG-B time symbol of the present invention, in step S1, input the IRIG-B time symbol, the input IRIG-B time symbol can be AC ​​mode or DC mode .

[0021] In step S2, a high-precision time tag is provided, and the Beidou or GPS (Global Positioning System) satellite time can be received through the Beidou / GPS satellite receiver, and a high-precision time tag is generated.

[0022] In step S3, the IRIG-B time symbol is captured to obtain the original information of the IRIG-B time symbol, and the time characteristics of the IRIG-B time symbol are analyzed according to the provided high-precision time tag. Capture the IRIG-B time code unit, obtain the original information of the IRIG-B time code unit, and then analyze the time characteristics of the IRIG-B time code unit. Analyzing the time characteristic of the IRIG-B time symbol includes analyzing the width of the symbol and the width of the high level or hig...

Abstract

The invention belongs to the technical field of time signal analysis. A method for analyzing an IRIG-B time code element aims at solving the problem that IRIG-B code time synchronous signals cannot be evaluated through service time accuracy. The method for analyzing the IRIG-B time code element includes the following steps that firstly, the IRIG-B time code element is input; secondly, a high-precision time label is provided; thirdly, the input IRIG-B time code element is captured, and according to the provided high-precision time label, time characteristics of the IRIG-B time code element are analyzed. By means of the method, the time characteristics of the IRIG-B time code element are analyzed, the IRIG-B code time synchronous signals can be evaluated through the analysis result, and then the quality of the IRIG-B code time synchronous signals can be judged.

Description

technical field [0001] The invention belongs to the technical field of time signal analysis, in particular to a method for analyzing IRIG-B time symbols. Background technique [0002] IRIG (Inter Range Instrumentation Group) is the abbreviation of the American Range Instrumentation Group. The IRIG code is a time standard formulated by the American Range Command Committee. It is now widely used in military, commercial, industrial and many other fields. There are four parallel binary time code formats and six serial binary time code formats for IRIG codes, among which the IRIG-B time code format is the most commonly used. The IRIG-B code is a serial time code of one frame per second, each frame includes 100 IRIG-B time symbols, and the width of each time symbol is 10ms. According to the standard definition of IRIG-B codes, there are three types of IRIG-B time codes, namely P codes, 1 codes and 0 codes, P codes are flag bits, and 1 code represents binary 1 and 0 codes The ele...
