specific Embodiment approach 2

[0019] Specific embodiment two: the difference between this embodiment and the electric simulator of a kind of gyroscope described in specific embodiment one is that the analog sensitive data output by the function simulation module 1 refers to the satellite of the gyroscope simulated by the electric simulator The angular velocity data output by the gyroscope when it is running in space.

specific Embodiment approach 3

[0020] Specific embodiment three: the difference between this embodiment and the electric simulator of a gyro described in specific embodiment one is that the gyro signal output by the on-board device data interface circuit 4 means that the gyro is connected to the test system The signal data obtained in is composed of satellite sensitive data, satellite status data and checksum, and the satellite status data refers to temperature information data, power supply information data and command receiving status data.

[0021] One frame of the gyro signal described in this embodiment is composed of four bytes, wherein, the first byte and the second byte store satellite sensitive data, and the gyro is not really in a space operation state, so the satellite sensitive data is Invalid; the third byte stores the satellite status data, the fourth byte stores the checksum, and the checksum is used to check the sum of a group of data items, because the satellite sensitive data is invalid, so...

Abstract

The invention provides an electric simulator of a gyro, and relates to an electric simulator of a satellite facility, which aims at solving the problem that an electric simulator of a gyro and the gyro can not be simultaneously connected to a satellite test system in an existing facility or device. The electric simulator comprises a functional simulation module, a simulator data interface circuit, a power supply input interface circuit, a data driven interface circuit, a signal processing module, a satellite facility data interface circuit and a power supply output interface circuit, wherein simulation sensitive data signals output by the functional simulation module and gyro signals output by the satellite facility data interface circuit are isolated and synthesized in the signal processing module, the processed signal output end of the signal processing module is connected with the processed signal input end of the simulator data interface circuit, and the voltage output end of the power supply input interface circuit is connected with the voltage input end of the power supply output interface circuit. The invention realizes that the electric simulator of a gyro and the gyro can be simultaneously connected to a satellite test system, and is used for the satellite attitude control system or the whole-satellite test.

Description

technical field [0001] The invention relates to an electrical simulator of on-board equipment. Background technique [0002] The satellite electrical performance testing process includes component testing, subsystem testing and full-star testing. In the process of subsystem testing and full-star testing or in certain stages of the testing process, some auxiliary equipment or devices are needed to simulate real satellites. Equipment to achieve the purpose of sub-system or entire star electrical performance testing, these auxiliary equipment or devices that simulate real equipment are called electrical simulators. The electrical simulator mainly simulates the structure of the electrical interface of real on-board equipment, the processing of communication protocols, data flow and timing characteristics, etc. [0003] The electrical interface of the electrical simulator of the on-board equipment is completely consistent with the electrical interface of the simulated on-board e...
