Description

Technical field

[0001] The invention relates to an electrical simulator for on-board equipment. Background technique

[0002] The satellite electrical performance test process includes component test, sub-system test and whole-satellite test. During the sub-system test and whole-satellite test or at certain stages of the test process, some auxiliary equipment or devices are needed to simulate the real satellite. Equipment to achieve the purpose of sub-system or whole satellite 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 the real on-board equipment, the processing of the communication protocol, the data flow and the timing characteristics, etc.

[0003] The electrical interface of the electrical simulator of the on-board equipment is exactly the same as the electrical interface of the simulated on-board equipm...

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 .
