The network management platform adopts a polling manner to perform wireless communication with a plurality of GPS / Beidou dual-mode smart amplifying multi-path allocation equipment. A wireless communication module wirelessly transmits the work state of the GPS / Beidou dual-mode smart amplifying multi-path allocation equipment to the network management platform. The system supports two modes of GPS and Beidou, realizes remotely monitoring over the GPS / Beidou antenna feedback systems of the nation or the global through the Ethernet or mobile network, is simple to manage, has low cost, effectively reduces quantity of the antenna feedback system, lowers the construction difficulty and cost, and has high reliability.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a GPS / Beidou dual-mode intelligent amplification multi-channel distribution system with a monitoring function. Background technique [0002] Mobile communication is an indispensable and important part of today's social life, and it is also a public technology field that has developed rapidly in recent years. GPS / Beidou has become an international standard as a part of communication technology applications. At present, GPS / BeiDou has been widely used in navigation , measurement, communication and timing; in the field of mobile communications, GPS / Beidou timing mainly provides the reference synchronization signal for data transmission. [0003] The GPS / Beidou signal carries a fixed synchronization signal, which can provide the necessary timing service for all devices in the coverage area. CDMA, TDS, LTE and other technologies in the field of mobile communication use GPS / Beido...

Problems solved by technology

[0004] However, the current GPS / Beidou antenna feeder system has great defects. For example, there are usually multiple BBUs in a single mobile communication room, and each BBU needs to build a GPS / Beidou antenna feeder system one-to-one, resulting in numerous GPS / Beidou antennas and feeders. , the maintenance time is long, the cost is high, and it is difficult to coordinate with the site sky construction property, which may easily cause resistance and obstruction from the owners or residents; the GPS / Beidou sky receiving antenna is generally placed in the open air on the roof, cannot be blocked, and needs to be far away from the surrounding metal If you want to install multiple GPS / Beidou antennas on the roof, it will be even more difficult; the signal strength received by the GPS / Beidou antenna feeder system is affected by the number of connected satellites and the surrounding environment. In order to ensure that the BBU receives signal strength, the distance between the receiving antenna and the BBU is limited to a certain extent, which brings great difficulties to the site selection and subsequent expansion of the communication site computer room

Unified management is inconvenient. The GPS / Beidou antenna feeder system is spread all over the country and even all over the world. It has a wide area and a large number. It is difficult for the construction party to know which ones need maintenance and which ones need to be repaired due to failures. The management cost is high; , The GPS / Beidou signal is unstable and leads to out-of-synchronization. The RF feeder attenuates the GPS / Beidou signal greatly, resulting in limited feeder distance. The weak GPS / Beidou signal causes the BBU to easily lose synchronization, and the reliability is not high, which affects the work of the base station; Occupies a lot of resources, high investment cost, time-consuming, laborious and costly construction
