A Survival Control Method for Autonomous Sleep and Wakeup Based on External Measurement Information Correction

Abstract

The invention relates to an autonomous dormancy wake-up survival control method based on external measurement information correction. A photosensitive device and a temperature measuring device are arranged at the tail of a deep space impactor, and the photosensitive device collects light signals to determine whether it is day or night. The temperature measuring device measures the ambient temperature to prevent misjudgment caused by accidental blocking of the photosensitive surface of the photosensitive device and ensure the validity of the judgment. Periodically (1-2 hours) collect photosensitive information and temperature information, and transmit the photosensitive information and temperature information to the high-reinforcement module for comprehensive correction and judgment through continuous measurement, so as to realize the control of autonomous sleep and wake-up. The autonomous dormancy wake-up survival control method based on external measurement information correction provided by the present invention is simple and reliable, has low energy consumption and high redundancy, and can effectively realize the autonomous dormancy wake-up of a deep space impactor.

Description

technical field [0001] The invention relates to the technical field of deep space exploration aircraft, in particular to an autonomous dormancy wake-up survival control method based on external measurement information correction. 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] Comprehensive consideration of factors such a...

Problems solved by technology

[0004] Conventional self-management dormancy and wake-up strategies rely on on-device clock timing or external instructions. The problem encountered in impact detection is that the asteroid’s rotation characteristics are unknown in advance, and time-based dormancy and wake-up strategies are unreliable and need to be triggered by external events. It operates autonomously, without external instructions, and can only rely on its own sensitive external information
