Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention is a dual-channel acquisition method with different meshing code distances, which collects by adopting dual-channel time-sharing collection and dual-channel collection time intervals showing different meshing code distances, which can correctly reflect the jitter state of peripherals, It solves the defects caused by the traditional dual-channel acquisition well.

[0027] The specific method is described as follows:

Abstract

The invention relates to a dual-channel reliable collection method for different meshing codes. Dual-channel time sharing collection is adopted, and dual-channel collection time interval is in a mode of different meshing codes. Compared with the prior art, the dual-channel reliable collection method provided by the invention has the advantages of avoiding the collection leakage of various oscillation signals, and greatly improving the collection reliability, etc.

Description

technical field [0001] The invention relates to a signal collection technology in the rail transit field, in particular to a two-channel reliable collection method with different meshing code distances. Background technique [0002] In the field of rail transit, at present, the method of dual-channel simultaneous acquisition is generally adopted for the acquisition of peripheral status, that is, after the acquisition is started, two channels simultaneously collect the peripheral status with the same acquisition frequency within one acquisition cycle, and finally get The collection result of peripheral status. [0003] Using the above collection method to collect the peripheral state is relatively simple in technology, but it has the following defects: [0004] Assuming that there is regular jitter in the peripheral, if the sampling frequency used for dual-channel acquisition is the same as the jitter frequency or the sampling frequency is one-nth of the jitter frequency, im...
