Technical Field

Background
After the spacecraft is in orbit or the spacecraft lands, the mechanism is usually released and separated, so that the release signal detection technology is widely applied to the field of spaceflight. Generally, the detection of the release signal is mainly performed by the following methods: optical signal detection, image recognition detection, electric signal detection and mechanical signal detection. Wherein the optical signal detection mainly identifies the release of the releaser through an optical switch; the image recognition detection is to acquire the image information of the releaser in the releasing process and process the image information through an image recognition function to obtain a releasing signal; electrical signal detection generally identifies the separation of the dispensers by the on or off of the electrical connector connecting the dispensers. The mechanical release signal detection is a release signal detection method widely adopted at present due to the fact that related electronic equipment is few and signals are reliable. The mechanical release signal detection device is mostly realized by adopting a contact switch, and the commonly used contact switch is suitable for a release mechanism with abundant installation space, but for the release mechanism with narrow installation space, the installation of the commonly used contact switch is limited, and the technical requirement of release signal detection cannot be met.
