A system auxiliary power supply device for deep space impact detection in high impact environment

Abstract

A system auxiliary power supply device for deep space impact detection in a high-impact environment, which is realized by a piezoelectric system. The power supply of the data acquisition system in the impactor is jointly completed by the battery and the piezoelectric system. The battery is the main power supply, and the piezoelectric system is the auxiliary. power supply side. When the impactor is impacted by high overload, the piezoelectric system uses the acceleration of the impact process to generate electrical energy, which is used to provide auxiliary power for the data acquisition system. The system auxiliary power supply device for deep space impact detection under high impact environment of the present invention utilizes the large overload generated during the impact process to generate power to supply power for the data acquisition system, avoiding the impact on the data acquisition system when the battery is damaged under large impact overload, So as to effectively realize the reliable work of the data acquisition system.

Description

technical field [0001] The invention relates to an auxiliary power supply device for a deep space impact detection system in a high impact environment, and belongs to the technical field of deep space exploration aircraft. Background technique [0002] With the development and progress of space technology, the means of deep space exploration have developed from the initial overflight detection to multi-modal combined detection such as orbiting, landing, inspection, and sampling, realizing the leap from orbiting to landing, from the surface to the interior, and are moving towards three-dimensional detection, Internal depth detection direction development. Impact detection is an efficient means to achieve internal detection. It has the characteristics of simple and reliable structure, high integration, and flexible configuration. It can penetrate into the interior of celestial bodies with less resource consumption. [0003] The impactor is equipped with a data acquisition sys...
