Abstract

The invention discloses a high-speed acquisition method and a high-speed acquisition device of time domain reflection signals, and solves the problem that an existing acquisition method is high in cost and complex to control. The method comprises the following steps: determining the number of times of acquisition of the data acquisition device and the starting time during each acquisition according to target acquisition frequency and current acquisition frequency; performing data acquisition according to the determined number of times of acquisition and starting time to obtain an acquisition result; and determining the total acquisition result under the target acquisition frequency according to the acquisition result of each acquisition. Through the acquisition method, the low-frequency data acquisition device can be used for replacing a high-frequency data acquisition device, and the data acquisition cost is reduced.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and device for high-speed acquisition of time-domain reflection signals. Background technique [0002] Time-Domain Reflectometry (TDR) is often used to measure the characteristic impedance of the transmission line, and to locate the breakpoint and short-circuit point of the transmission line, etc. It is widely used in radar, cable obstacle test, optical cable obstacle test and other fields . [0003] In the application process of time domain reflection technology, after the signal source transmits the signal, the signal will be reflected due to the change of the characteristic impedance of the transmission line during the transmission process of the signal, which is the time domain reflection signal. Therefore, the characteristic impedance of the transmission line can be calculated by collecting the reflection signal in the time domain. [0004] At...
