specific Embodiment approach 1
[0010] Specific implementation mode 1: the following combination figure 1 This embodiment will be described in detail. An electrical simulator for a gyro, which includes a functional simulation module 1, a simulator data interface circuit 2, a power supply input interface circuit 5 and a data drive interface circuit 7. The drive data output terminal of the data drive interface circuit 7 and the functional simulation module 1 The drive data input terminal is connected, the control signal output terminal of the simulator data interface circuit 2 is connected to the control signal input terminal of the functional analog module 1, and the voltage output terminal of the power supply input interface circuit 5 is connected to the voltage input terminal of the functional analog module 1. It also includes a signal processing module 3, a satellite device data interface circuit 4, and a power supply output interface circuit 6. The control signal output end of the simulator data interface c...
specific Embodiment approach 2
[0019] Embodiment 2: The difference between this embodiment and the electric simulator of a gyroscope described in Embodiment 1 is that the simulated sensitive data output by the functional simulation module 1 refers to the simulation of a satellite equipped with a gyroscope by the electric simulator Angular velocity data output by the gyro when operating in space.
specific Embodiment approach 3
[0020] Embodiment 3: The difference between this embodiment and the electrical simulator of a gyro described in Embodiment 1 is that the gyro signal output by the on-board device data interface circuit 4 refers to the gyro being connected to the test system The signal data obtained in this is composed of satellite sensitive data, satellite status data and checksum. The satellite status data refers to temperature information data, power supply information data and instruction reception status data.
[0021] One frame of the gyro signal described in this embodiment is composed of four bytes. The first byte and the second byte store sensitive satellite data. The gyro is not really operating in space, so the satellite sensitive data is Invalid; the third byte stores the satellite status data, and the fourth byte stores the checksum. The checksum is used to verify the sum of a group of data items. Because the satellite sensitive data is invalid, the checksum is also invalid .
