Carrier rocket universal integrated electronic system based on VPX architecture

Abstract

The invention relates to the field of rocket electronic systems, and discloses a carrier rocket universal integrated electronic system based on a VPX architecture. A military VPX / OpenVPX standard architecture is adopted, and control system equipment and measurement system equipment are integrally designed on a rocket through the VPX-based standard integrated design; integrated electronic equipmentis arranged on a rocket according to the specific design conditions of the overall rocket and an electrical system, common parts of different integrated electronic equipment are stripped into universalized modules according to the functions of the electronic system, and the universalized modules are organically integrated according to the functions and define the functions through software; and unified power supply is carried out between the universalized modules through a backboard power line, and information interaction is carried out through an inter-board bus, so that the problem that thenumber of electronic equipment on the rocket is large is solved, the integration degree of the rocket is improved, and the purposes of weight reduction and cost reduction are achieved.

Description

technical field [0001] The invention relates to the field of rocket electronic systems, in particular to a general integrated electronic system of a launch vehicle based on a VPX architecture. Background technique [0002] The electronic system on the launch vehicle generally includes a control system and a measurement system. The functions of the two systems are relatively independent, and there are hardly many integrated fusion designs, and both systems contain multiple electronic devices, such as flight control computers, Distributors, controllers at all levels, satellite navigation receivers, editors at all levels, comprehensive information processing equipment, etc. The number of computer-type stand-alone equipment on some multi-stage launch vehicles is often 6-10, or even more. [0003] At the same time, because the electronic equipment on the traditional multi-stage launch vehicle is often in charge of different research and development units and designed independent...

AI Technical Summary

Problems solved by technology

[0003] At the same time, since the electronic equipment on the traditional multi-stage launch vehicle is often in charge of different research and development units and designed independently of each other, the size and interface of each circuit board in the equipment are different, so it is impossible to achieve board-level universal use

This situation, while resulting in a low degree of integration of electronic equipment on the rocket, further increases the number of electronic equipment on the rocket

[0004] However, the large number of equipment on the rocket has obvious disadvantages. More equipment means more shells. The shells of the equipment on the rocket are often designed to be thicker and heavier in order to adapt to complex mechanical environmental conditions. Many electronic equipment on the rocket The shell of the rocket is very unfavorable to the weight reduction of the rocket; more electronic devices lead to more cables connecting the electronic devices, which directly increases the weight of the cable network on the arrow, resulting in a larger overall system mass and increased costs

[0005] At the same time, due to the low degree of integration of electronic equipment on the rocket, and the technical status of each circuit board of different electronic equipment is not the same, the possibility of system failure increases

Different technical states will also increase the workload of testing, quality control, acceptance, etc., directly increasing the cost; and there is a certain degree of duplication and waste in the internal computing resources, storage resources, power resources, etc. of each device, so it needs to be improved
