Water drop measuring system in space environment

Abstract

The invention relates to a water drop measuring system in a space environment. The water drop measuring system comprises a mechanical supporting structure, a photoelectric detection module, a signal processing module and an information input and output module, wherein the mechanical supporting structure provides a mounting platform for supporting and fixing various components; the photoelectric detection module is used for acquiring water drop information and detecting transmission light and catadioptric light of water drops by adopting an energy detection method or an imaging method; the signal processing module is used for calculating to obtain water drop size information according to original data obtained by means of the photoelectric detection module, and controlling to output an analog voltage; and the information input and output module realizes power supply and data communication of the system. The water drop measuring system is small in size and light in weight, has high reliability and stability, and can meet the operation safety of a life support system under the strict conditions of space environment weightlessness and weight and volume requirements.

Description

technical field [0001] The invention belongs to the technical fields of target characteristic analysis, target detection and target recognition, and relates to a water drop measurement system in a space environment. Background technique [0002] Environmental control and life support systems are essential systems for any manned spacecraft. It is a significant sign to distinguish whether a spacecraft is a manned spacecraft, and it is one of the key technologies that must first be broken through in the development of aerospace technology from unmanned spaceflight to manned spaceflight. Among them, the environmental control system, commonly known as the air conditioning system, is a very important and quite complex system on the spacecraft. It is a system directly related to the health and life safety of astronauts, and it is also an important system related to the successful completion of space missions. [0003] The basic task of the air conditioning system is to create a ba...

Problems solved by technology

[0013] However, if the air conditioning system fails (such as a broken filter) or stops working, larger water droplets will circulate into the spacecraft environment, which will not only endanger the life of the astronauts, but also damage the electronic equipment in the cabin and affect the space mission. implementation

[0014] In the existing technology, a filter is usually added to the pipeline. This method is a contact measurement. The size of the water droplet is detected by two dimensions, which can only be measured in one direction, and the measurement accuracy is poor. It does not have the ability to measure three-dimensional and multi-directional simultaneously.
