GPS intelligent synchronous time service system

Abstract

The invention discloses a GPS intelligent synchronous time service system. The GPS intelligent synchronous time service system comprises a GPS module, a Master clock server, a plurality of Slave clockservers, a plurality of BBU devices and a DC-to-AC power supply module. The Master clock server is connected with the GPS module through a feeder line; the Slave clock servers are connected with theMaster clock server through a network cable, the BBU equipment is connected with the Slave clock servers through network cables, and the DC-to-AC power supply module is used for supplying power to theMaster clock server and the Slave clock servers. According to the invention, through the cooperation of the Master clock server and the Slave clock servers, the installation and use of the GPS antenna and the feeder line can be reduced; the whole system only needs one set of GPS antenna and one feeder line, the BBU equipment and the GPS equipment do not need to be cascaded by a large number of feeder lines, the deployment is simple, the occupation of sky surface resources and machine room space can be greatly reduced, the maintenance and the expansion are convenient, the failure rate is effectively reduced, and the steady communication switching performance is ensured.

Description

technical field [0001] The invention belongs to the communication field, in particular to a GPS intelligent synchronous timing system. Background technique [0002] With the increase in the number of stations, the pressure on station construction is increasing, and users are more aware of the radiation of signal stations. As a result, it is difficult for some stations to enter the site, and the owner obstructs them. The site selection work is extremely difficult. The idea of ​​centralized placement of BBU equipment came into being. The radio frequency unit is at the signal coverage point, and the control unit is placed in a certain computer room. This not only solves the problem, but also facilitates the centralized management of the BBU unit and facilitates operation. BBU devices are installed in a centralized manner, and GPS also needs to be installed in a centralized manner. The resulting problem is that a large number of GPS antennas and multiple GPS cables need to be in...

AI Technical Summary

Problems solved by technology

BBU devices are installed in a centralized manner, and GPS also needs to be installed in a centralized manner. The resulting problem is that a large number of GPS antennas and multiple GPS cables need to be installed in the same BBU pool room, resulting in limited installation of antenna resources and difficulty in expansion. There is a GPS alarm, which affects handover indicators such as VoLTE

In addition, a large number of BBU equipment GPS is cascaded, resulting in more fault points and extremely difficult maintenance
