Embodiment

[0048] The deployment state detection system of the flexible shading cover, the flexible shading cover is provided with support rods, and the two ends of the support rods are provided with support seats, and the support seats can provide necessary support and optical passage for the deployment state detection system. The system for detecting the unfolded state of the flexible shading cover includes a transmitter and a receiver, and the transmitter and the receiver are respectively installed at both ends of the support rod, such as figure 1 with figure 2shown. Among them, the transmitter needs two power supply lines, the positive pole and the negative pole of the power supply, and the receiver needs two power supply lines, the positive pole and the negative pole of the power supply, and outputs the telemetry signal. A total of three wires are required for connection. In the tooling state, the power supply positive pole and the power supply negative pole of the transmitter and...

Abstract

A flexible light shielding cover unfolding state detecting system comprises a transmitter and a receiver, wherein the transmitter and the receiver are installed at both ends of a supporting rod of a flexible light shielding cover; and the transmitter is used for emitting light waves with the wavelength of 850 nm to 950 nm, and the receiver judges whether the flexible light shielding cover is unfolded according to the light waves emitted by the transmitter. The flexible light shielding cover unfolding state detecting system effectively solves the problem of detecting the spatial unfolding stateof the flexible light shielding cover, and is low in cost and easy to implement.

Description

technical field [0001] The invention relates to a detection system for the deployment state of a flexible shading cover, which belongs to the field of on-orbit deployment state monitoring of flexible materials of spacecraft. Background technique [0002] At present, the material of hoods for remote sensing satellites is generally solid rigid materials such as composite materials. With the increase in the volume of remote sensing payloads and the limitation of the installation volume of launch vehicles, on some remote sensing satellites, the rigid solid shading system has been unable to meet the needs of use. , the flexible and expandable sunshade began to enter the designer's sight. However, the in-orbit deployment state and bending degree of the flexible and expandable sunshade are a link that affects the "life" of the remote sensing payload. [0003] A remote sensing satellite is the first remote sensing satellite in my country to apply a flexible and expandable hood. The...
