Description

Technical Field

[0001] This invention belongs to the field of satellite design technology, specifically relating to an electromagnetic inspection-type automatic adjustment system for the center of mass of a satellite. Background Technology

[0002] After launch, the satellite's center of mass changes during its on-orbit operation due to factors such as thruster gas expulsion, fuel consumption, structural deformation, and gravity release. These changes affect the satellite's attitude and orbit determination accuracy. Therefore, a center of mass adjustment mechanism is needed for this purpose; that is, by precisely adjusting the satellite's center of mass in orbit, high-precision mass characteristics and the normal operation of some payloads can be ensured.

[0003] Meanwhile, some anomalies or malfunctions are inevitable during satellite operation. For example, when the satellite's center of mass changes, some satellite payloads may malfunction. To prevent the entire system from paralyzing or failing due to the failure of certain components, it is necessary to quickly carry out status detection, fault diagnosis, and health assessment through telemetry parameters. However, traditional center of mass adjustment devices can only achieve center of mass balance by adjusting the counterweights, and cannot provide data support for fault diagnosis. Summary of the Invention

[0004] The purpose of this invention is to address the technical shortcomings of existing satellite center-of-gravity adjustment devices, which can only achieve center-of-gravity balancing by adjusting counterweights and cannot provide data support for fault diagnosis. This invention proposes an electromagnetic inspection-type automatic satellite center-of-gravity adjustment system, which simultaneously realizes on-orbit autonomous adjustment of the satellite's center-of-gravity position and provides fault diagnosis support services.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] The electromagnetic inspection-type satellite centroid automatic adjustment system includes a device body and a guide rail. The device body is mounted on a device body support and includes a temperature sensor, a positioning module, a 360° panoramic camera, a power supply module, and a centroid control module. An electromagnetic coil corresponding to the sensing element is provided at the bottom of the device body support. The sensing element is set on the guide rail and is used to drive the device body to move according to the control command. The power module and the center of mass control module are installed in the middle of the device body, while the positioning module, the 360° panoramic camera and the temperature sensor are installed in the upper part of the device body. The field of view of the 360° panoramic camera is not blocked by the temperature sensor and positioning module on the device body. Optionally, a slot is provided on the guide rail, which is installed and cooperates with the support of the device body. A sensing element is provided in the slot, which corresponds to the position of the electromagnetic coil of the device body. Optionally, the guide rails are respectively arranged in the X, Y and Z directions of the three-dimensional coordinate system OXYZ with the satellite's geometric center as the origin; The temperature sensor is used to detect the ambient temperature at the current location of the device body. The positioning module is used to determine the current location of the device body; The 360° panoramic camera is used to provide full image coverage of the satellite's internal equipment, providing data support for satellite fault diagnosis and health management. The power module input is connected to the satellite primary power module, and the output is connected to the temperature sensor, positioning module, 360° panoramic camera and centroid control module; The center of mass control module is used to generate control commands based on the current position of the center of mass, the specified position of the center of mass, and the position of the device body to drive the movement of the device body to change the mass distribution of the entire satellite, thereby achieving center of mass balancing. At the same time, the temperature sensor detects the ambient temperature of the current location, and the 360° panoramic camera can achieve full image coverage of the satellite's internal equipment, providing data support for satellite fault diagnosis and health management.

[0007] The electromagnetic inspection-type automatic adjustment method for satellite centroid includes information acquisition, centroid position determination, fault diagnosis, and health management. The information collection specifically includes three parts: temperature collection, location collection, and image collection. The temperature acquisition is achieved by detecting the ambient temperature at the current location of the device body using a temperature sensor. The location acquisition determines the current location of the device body through the positioning module; The image acquisition uses a 360° panoramic camera to capture images of the satellite's internal equipment, and the acquired images provide data support for satellite fault diagnosis and health management. The determination of the center of mass position is specifically as follows: the center of mass control module generates control commands based on the current center of mass position of the entire satellite and the current position of the device body, and passes alternating current into the electromagnetic coil of the device body, generating an alternating electromagnetic field between the device body and the sensing element. This electromagnetic field generates eddy currents in the sensing element, and the electromagnetic field and the eddy currents generate a repulsive force, thereby pushing the device body to move in a straight line along the guide rail, thus determining the center of mass position. The aforementioned fault diagnosis and health management refers to the process of the device performing inspections while it is in motion, sensing the ambient temperature of its location and providing full image coverage of the surrounding satellite equipment. Specifically, it relies on the ambient temperature of the device's location, the device's current location, and images of the satellite's internal equipment collected by the 360° panoramic camera to determine whether fault settings and health characteristics have been met, and then feeds this information back to the device.

[0008] Optionally, the number of the device body can be selected and adjusted according to the satellite's center of mass adjustment requirements.

[0009] The sensor drive unit mounted on the guide rail moves according to the control command. The center of mass control module generates control commands based on the current position of the center of mass, the designated position of the center of mass, and the position of the device body to drive the movement of the device body and change the mass distribution of the entire satellite, thereby achieving center of mass balancing. The specified centroid position is the centroid position determined based on the satellite centroid adjustment requirements; Meanwhile, temperature sensors detect the ambient temperature at the current location, and 360° panoramic cameras provide full image coverage of the satellite's internal equipment, offering data support for satellite fault diagnosis and health management. The device includes a main body and a guide rail, wherein: the main body includes a temperature sensor, a positioning module, a 360° panoramic camera, a power module, and a center of gravity control module; an electromagnetic coil is disposed on the main body. The temperature sensor is used to detect the ambient temperature at the current location of the device body. The positioning module is used to determine the current location of the device body; The 360° panoramic camera is used to provide full image coverage of the satellite's internal equipment, providing data support for satellite fault diagnosis and health management. The power module's input terminal is connected to the satellite's primary power module, and its output terminal is connected to the temperature sensor, positioning module, 360° panoramic camera, and centroid control module.

The automatic adjustment system generates control commands through the center of mass control module to autonomously control the movement of the device body to change the mass distribution of the entire satellite, thereby achieving the purpose of center of mass balancing; 2. While the automatic adjustment system achieves centroid balancing, the temperature sensor can sense the ambient temperature at the current location, and the 360° panoramic camera can achieve full image coverage of the satellite's internal equipment, providing data support for satellite fault diagnosis and health management.

[0021] Furthermore, the working principle of the electromagnetic inspection-type satellite centroid automatic adjustment system is as follows: The center of mass control module 9 generates control commands based on the current center of mass position of the entire satellite and the current position of the device body.
