Abstract

A signal backup system and method of a near-end machine in an active DAS system, the system includes a state detection unit, a backup processing unit and at least two power distribution units, the backup processing unit is provided with a backup signal output port and the number is not less than the power The number of backup access ports of the distribution unit, the state detection unit is provided with a backup signal input port and a number of radio frequency access ports not less than the number of power distribution units; the input of the power distribution unit is connected to a signal source, and one of the output ports is connected to One radio frequency access port, the other output port is connected to a backup access port, and the backup signal output port is connected to the backup signal input port; when an access exception occurs at any radio frequency access port, the backup processing unit controls the abnormal access port. The signal source connected to the radio frequency access port is connected to the backup processing unit, and the signal of the backup processing unit is connected to the backup signal input port, which not only ensures the reliability but also reduces the hardware cost, and improves the cost performance of the system.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a signal backup system and method for a near-end machine of an active DAS system. Background technique [0002] With the rapid development of mobile communication network construction and customer application requirements, the coverage and quality requirements of indoor signals are increasingly strong. Active indoor DAS (Distributed Antenna System, Distributed Antenna System) has gradually become the solution to achieve high-quality and deep indoor coverage. Preferred option. However, after more and more applications to active DAS systems, customers' requirements for system reliability have gradually increased, especially concerns about the reliability of active components. Such as figure 1 As shown, in some large-scale projects with high importance, the 1+1 backup access scheme is adopted to improve product reliability. 1+1 backup brings more hardware usage while...
