Standardized large-and-medium-sized satellite low-frequency wired signal conditioning device

Abstract

The invention provides a standardized low-frequency wired signal conditioning device. The device comprises a standardized signal conditioning box and a satellite-to-ground contact adapter box. The standardized signal conditioning box is served as a core of the standardized large-and-medium-sized satellite low-frequency wired signal conditioning device and completes a satellite wired download low-frequency signal and an upper satellite wired control signal of a satellite low-frequency signal acquisition and control terminal and other functions. In the invention, general and special-purpose portions of the signal conditioning device can be thoroughly separated and universality of the conditioning device is increased maximumly so that an only difference of the different satellite low-frequency wired signal conditioning devices is the satellite-to-ground signal contact adapter box; and all satellite low-frequency wired signal conditioning modules are integrated into one 2U standardization signal conditioning box, the size is small and an integrated level is high.

Description

technical field [0001] The invention relates to a standardized low-frequency cable signal conditioning device, in particular to a standardized large and medium-sized satellite low-frequency cable signal conditioning device. Background technique [0002] With the continuous increase in the function and quantity of large and medium-sized satellites in national defense and space science research, higher and higher requirements are put forward for satellite testing. It is necessary to detect satellites efficiently, quickly and with full coverage, and provide real high-value, Highly reliable test conclusions provide favorable technical support for the satellite development process. [0003] Large and medium-sized satellites refer to satellites with a mass greater than 500kg. Among them: satellites with a mass of 500kg to 1000kg are called medium-sized satellites, and satellites with a mass of more than 1000kg are called large satellites. The satellite low-frequency cable signal ...

AI Technical Summary

Problems solved by technology

[0005] First, the integration level is low, the functional module interface is not uniform, and the equipment volume is relatively large, which makes it difficult to meet the increasing test requirements of satellites and the miniaturization and high integration requirements of satellite test equipment

[0006] Second, although modularization has been achieved, the satellite low-frequency cable signal conditioning equipment is still customized according to the specific conditions of the satellite, and the general-purpose part of the signal conditioning equipment is not completely separated from the special-purpose part, resulting in the equipment not being able to be used on other satellite models, resulting in A great waste of equipment resources, a lot of repetitive design work is required in the development of equipment, which is time-consuming and laborious
