Description

technical field [0001] The invention belongs to the technical field of the mobile communication industry, and in particular relates to a multi-channel adjustable BDS / GPS time service device and a time service method. Background technique [0002] Time service refers to the equipment in the communication network, which realizes the synchronization between network equipment by obtaining a unified clock source signal. Currently, mobile communication networks generally use satellite on-board clocks as the clock source. The Global Positioning System (GPS) of the United States and the BeiDou Navigation Satellite System (BDS) of China both have the ability to serve time for mobile communication networks. [0003] In the field of communication and measurement, with the development of science and technology, more and more equipments need to be timed in the computer room. In addition, the computer room is relatively tight now, and a large number of devices are concentrated in one comp...

Problems solved by technology

[0003] In the field of communication and measurement, with the development of science and technology, more and more equipments need to be timed in the computer room. In addition, the computer room is relatively tight now, and a large number of devices are concentrated in one computer room. The longest distance between devices may be > 300 More than 1000 meters, the original time service radio frequency splitting technology is simple and the overall amplification attenuation and filtering can not meet the precise adjustment of the timing signal between the time service terminal and the equipment 0 ~ 1000 meters (and above)

If the signal strength is too high, the timing chip of the device closer to the timing terminal will be burned; if the signal strength is too small, the timing signal will not be detected by the device closer to the timing terminal
