Description

technical field [0001] The invention relates to the technical field of satellite navigation and communication, in particular to a high-reliability and high-density large-capacity inbound signal cluster processing method and device. Background technique [0002] In the traditional satellite navigation ground station signal processing system, a parallel architecture is adopted according to different frequency points and systems, and it is divided into multiple signal processing links. Each link is composed of multiple signal processing devices adapted to each other. Independent, one signal uses a set of signal processing equipment, which is highly specialized and has many redundant equipment. Under this architecture, in order to ensure the reliability of the system's uninterrupted operation, usually multiple key signal processing equipment are separately :1 backup, which is equivalent to duplicating all signal processing equipment in one set. Half of the equipment in the syste...

[0003] However, the above-mentioned traditional ground station signal processing system architecture and method have the following disadvantages: (1) Under this signal processing architecture, the function of each signal processing device is fixed, and cannot be easily changed after configuration, and the flexibility is poor; (2) Signal processing Each signal processing device of the link needs 1:1 backup, which doubles the number of system devices, and the cost of construction and maintenance is very high; (3) each backup device is only used as the backup of the only master device, which is relatively stable During operation, nearly half of the equipment is idle, which increases the power consumption of the system and the backup utilization rate is very low; (4) when a signal processing node is in the state of main equipment maintenance and standby equipment, there is no backup equipment at this node, If the standby equipment also fails at this time, it will cause the interruption of the system signal processing path, and the risk of system service interruption is high. Therefore, the present invention proposes a high-reliability and high-density large-capacity inbound signal cluster processing method and device to solve the problem of existing technologies. problems in
