Embodiment 1

[0055] refer to figure 1 , shows a flow chart of the steps of a magnetic polarity test method provided by an embodiment of the present invention, as figure 1 As shown, the magnetic polarity test method may specifically include the following steps:

[0056] Step 101: After starting the magnetic polarity testing system, determine the magnetic torquer to be tested.

[0057] The embodiment of the present invention can be applied to the scene of detecting the magnetic polarity of the connector end of the magnetic torque device.

[0058] Magnetic Torquer (Magnetic Torquer) refers to a device that generates a dipole magnetic moment. The magnetic moment of the spacecraft interacts with the geomagnetic field where it is located to generate magnetron torque, which is used for attitude control or momentum management of the spacecraft.

[0059] There are generally two types of magnetic torque devices: air core coil and iron core coil. Magnetic torquers are often used in conjunction wi...

Embodiment 2

[0095] refer to figure 2 , shows a schematic structural view of a magnetic polarity testing device provided by an embodiment of the present invention, as figure 2 As shown, the magnetic polarity testing device 200 may specifically include the following modules:

[0096] The magnetic torque device determination module 210 is used to determine the magnetic torque device to be tested after starting the magnetic polarity test system;

[0097] A pulse width command sending module 220, configured to send a pulse width command to the magnetic torquer to be tested;

[0098] The magnetic polarity data detection module 230 is used to detect the magnetic polarity data of the connector end of the magnetic torque device based on the bipolar Hall sensor probe after the pulse width command is successfully sent;

[0099] A magnetic polarity data sending module 240, configured to send the magnetic polarity data to satellites.

Abstract

The embodiment of the invention discloses a magnetic polarity testing method and device. The method comprises the steps that after a magnetic polarity testing system is started, dtermining a to-be-tested magnetic torquer; sending a pulse width instruction to the to-be-tested magnetic torquer; after the pulse width instruction is successfully sent, detecting magnetic polarity data of the connectorend of the magnetic torquer based on a bipolar Hall sensor probe; and sending the magnetic polarity data to a satellite. The embodiment of the invention can adapt to different satellites of differenttest platforms and has good universality, the whole test process can be completed by a single person without cooperation of an electric test room and a hall, the test time is flexible, other content tests of the whole satellite are not influenced, the limitation of the test implementation process is reduced, the connection steps are simple and easy to operate, a complete closed loop can be formedwith the whole satellite test process, and the test result can be directly broadcasted to the network so as to facilitate recording and interpretation.

Description

technical field [0001] The invention relates to the technical field of satellite magnetic polarity testing, in particular to a magnetic polarity testing method and device. Background technique [0002] Using the traditional compass method to measure the polarity of the magnetic torque device is cumbersome, and the pointer swing is not sensitive. Especially when measuring the magnetic torque device with a small magnetic moment, the pointer hardly swings, which makes the polarity result of the magnetic torque device unclear and easily causes polarity. There is a great risk of misjudgment. After the magnetic torque device is installed in the whole satellite, due to the different installation positions of the magnetic torque device in different satellites, it is difficult to test, it is easy to damage the satellite and other components, the test complexity is high, and there are many safety hazards. [0003] At present, the polarity test of small satellite control sub-system co...
