Abstract

The invention relates to a method, a device and equipment for detecting second pulse input signal inversion and automatically correcting an error. The method comprises the following steps of: receiving a second pulse input signal; detecting the second pulse input signal, and judging whether the second pulse input signal is inverted or not; when the second pulse input signal is inverted, carrying out inversion error correction processing on the second pulse input signal; and outputting a normal second pulse input signal. The invention makes the system normally work, improves the compatability of the equipment and saves the installation and debugging time of the equipment through detecting the received second pulse input signal, judging whether the second pulse input signal is inverted or not and carrying out the inversion error correction processing on the second pulse input signal.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, device and network equipment for detecting phase inversion of a second pulse input signal and automatically correcting errors. Background technique [0002] In the existing mobile communication 3G (third generation mobile communication system) network construction, the 1588 technology is the key technology adopted in the TD-SCDMA system. Among them, the 1588 signal is specifically composed of 1PPS (1PulsePer Second, pulse per second) signal and TOD (Time of Day, daily timing) signal composition. [0003] At present, there is no unified interface standard for devices using the 1PPS function. Some use the RS232 interface standard, and some use the RJ45 interface standard. As a result, when devices from different manufacturers are connected to each other, they will face the problem of different interface standards. [0004] In the prior art, when the equipment adopti...
