Carrier rocket electrical system based on FC-AE-1553 high-speed bus

Abstract

The invention discloses a test method of a carrier rocket electrical system based on an FC AE 1553 high-speed bus. The method comprises the following steps that S1, a test program starts, a ground host is initialized to be a network controller of the FC-AE-1553 high-speed bus, and other devices of the electrical system are initialized to be network terminal devices of the FC-AE-1553 high-speed bus; S2, after test indexes of each device of a rocket and the ground are qualified, a ground host delivers a control right to a comprehensive control computer; S3, the ground host sends a primary engineignition instruction to a comprehensive actuator, and the comprehensive control computer globally broadcasts a takeoff moment to the FC-AE-1553 high-speed bus after receiving takeoff and enters navigation guidance and rocket attitude control; and S4, a data management center collects measurement data of a carrier rocket, then evaluates a health degree of the rocket and sends an evaluation resultto the comprehensive control computer.

Description

technical field [0001] The invention relates to a launch vehicle electrical system based on FC-AE-1553 high-speed bus, in particular to a launch vehicle electrical system based on high-speed bus information interaction, belonging to the technical field of launch vehicle electrical system design. Background technique [0002] At present, the competition in the field of space launch is becoming increasingly fierce. All major aerospace countries are launching or developing low-cost launch vehicles. These rockets have a high degree of automation, a short development cycle, and strong versatility. The use of advanced intelligent development and production models greatly reduces the launch cycle and cost of rockets. , Compared with my country's traditional launch vehicle research and development model, it has great advantages. As one of the most important systems of the launch vehicle, the electrical system can achieve high reliability, health management, and rapid test launch beco...

AI Technical Summary

Problems solved by technology

Traditional launch vehicle electrical systems are large in scale and complex in structure, low in integration, complex in bus types, and low in bus throughput, which seriously affect the carrying capacity. Facing the demand for rocket fault diagnosis and health monitoring functions under the new situation, due to the high power output and high dynamic characteristics of the rocket engine, high sampling rate and high throughput support of the bus are required, and the traditional rocket electrical system architecture is difficult to meet. Therefore, it is necessary Develop a new generation of launch vehicle electrical system with high-speed information interaction, high reliability and high integration
