Embodiment 2

[0046] Such as figure 2 As shown, it is a flow chart of a rocket flight data redundancy processing method provided by this application, which includes the following steps:

[0047] s1. Receive preliminary output values ​​from the first processor 10 and the second processor 20;

[0048] s2. Determine the corresponding standard data according to the preliminary output value of the first processor 10; the preliminary output value includes flag information, and the flag information is the time interval information between the current state of the rocket and the initial launch. The corresponding standard data is queried from the standard database according to the tag information. The standard database is the status information of each time node after the rocket launch, which is calculated manually according to the launch conditions of the rocket, including position information, attitude information and speed information, etc. For example, the rocket status information in the stan...

Abstract

The invention discloses a rocket flight data redundancy processing system and method. The system includes an inertial measurement unit DMA for receiving inertial measurement unit data, a GPS communication DMA for receiving GPS data, a first processor, a second processor and a detection output module, wherein the first processor and the second processor share a memory, both the first processor andthe second processor can access the inertial measurement unit DMA and the GPS communication DMA, the first processor and the second processor are provided with the same flight control program, the detection output module is used for receiving preliminary output values of the first processor and the second processor and determining difference between the preliminary output value of the first processor and standard data; if the difference is less than set difference, the preliminary output value of the first processor is taken as an output final value; if the difference is greater than or equalto the set difference, the preliminary output value of the second processor is taken as the output final value. The system is advantaged in that power consumption is reduced, and cost is saved.

Description

technical field [0001] The present disclosure generally relates to the technical field of rocket flight, and specifically relates to a system and method for redundant processing of rocket flight data. Background technique [0002] In previous launch vehicles, there was a dual-redundant master-slave backup system with channel selection redundancy management. The system consists of two sets of sensors, two sets of data input / processing / output devices and a system selector. The two subsystems can be of the same type or heterogeneity. The two systems work in parallel, and the slave system is in an offline hot backup state. When both systems are working normally, the online working system does not switch. When a system sends out a fault alarm signal, the system selector decides whether to switch online. When both systems send fault alarm signals, the system fails. [0003] The system selector consists of two parts: redundancy management logic (software) and switching device (...
