Embodiment 1

[0037] A four-sided reference ring structure Figure 2A Indicated. The X and Y represent the size of the reference ring length and wide, which consists of several joints, including 4 knots, symmetrical straight copper strips (ie Figure 2A In the arrow refers to it), and several linear copper strips (ie Figure 2A Mix M1 and M2). Among them, the reference ring wide side (ie Figure 2A The number of copper strips of the line Y is M1, long side (ie Figure 2A The number of linear copper strips is M2 in the middle x shown. The present invention defines the number M1 M1 of the linear copper strip, M2 is as follows:

Abstract

The invention provides a method for designing and debugging a special-shaped reference ring. The method includes the following steps: in the first step, the size of the reference ring is determined according to the measured special-shaped transponder, and the size of the reference ring is determined to be consistent with the size of the transponder. This makes two copper rings with dual output, and measures the inductance value C of the entire copper ring A ; In the second step, in order to ensure the uniform distribution of the magnetic field, the copper ring is uniformly cut, that is, the length of each copper strip is basically the same, and the length of a single copper strip cannot exceed 300mm, and the cutting is not performed at the corner; the third step is tuning, each The tuning circuit at the frequency point is equivalent to one in which only the capacitance C can be adjusted, and the capacitance value C can be adjusted according to the required resonance frequency; through the above method, special-shaped reference rings for various special-shaped transponders can be produced to meet the needs of special-shaped transponders. Calibration requirements; and the tuning steps of the reference loop simplifies the tuning circuit and debugging steps of the existing reference loop.

Description

Technical field [0001] The present invention relates to the field of railway communication signals, and more particularly to a reference ring of an expanded reference area. Background technique [0002] The reference ring is a cyclic conductor around the effective reference region, is a calibration tool consistent with the transponder reference area. Mainly the uplink and RF field consistency of the calibration transponder, input and output characteristics, and uplink features. In response to the current rail application, it can be divided into standard dimensional transponders and large-size transponders according to standard TB / T 3544, and have their respective reference loops production standards. However, when the CBTC mode is currently realized, the wake-up zero setting of the unmanned sleep wake-up function is called an extended transponder, and there is no applicable extended reference ring. In order to perform the extensive transponder, this shaped transponder related t...
