Abstract

The invention provides a full-redundant erection system, and aims at achieving full redundancy of the system function under the condition that the single-machine products are decreased, simplifying the system, improving the system reliability and reducing the requirement on the single-machine product reliability. The full-redundant erection system comprises a hydraulic system, a control system, a power supply and distribution system, a performing mechanism and an erection bearing structure which are interconnected according to a cross redundancy structure. With the adoption of the full-redundant erection system, the system reliability is improved, and the requirement on the single-machine reliability is reduced; the system composition is simplified; the quantity of single-machine products is decreased; the used space for the structure is small; the reliability is high; the requirement on the single-machine reliability is reduced; the integrity is high; any fault in the system can be quickly recognized or located according to a reliability map of the system.

Description

technical field [0001] The present invention relates to the technical field of launch, and more specifically, to a fully redundant erecting system. Background technique [0002] Generally, system redundancy generally adopts single-machine product redundancy in the system, and each subsystem has its own internal redundancy according to the reliability indicators assigned to them, resulting in some links of the entire system being redundant, and some links being less redundant. Although the system is reliable The performance has been improved, but the system is complicated, there are many components, and the system is huge and bloated, but the actual effect is very small. If the system fails, it is also very difficult to identify and locate the problem. [0003] In general, the design usually assigns the reliability indicators according to the subsystems and distributes them separately. Each subsystem performs the internal reliability redundancy design of each system accordin...
