The invention discloses a high-speed
momentum wheel rotational
speed test device and a method thereof, and the test device is mainly composed of a standard
metal electromagnetic shielding chassis, an AT96
bus motherboard, an AT96
bus AC / DC power supply board, an AT96
bus CPU board, an AT96 bus
momentum wheel pulse acquisition board.
Momentum wheel rotational speed pulses are acquired by the AT96 bus
motherboard, pulse signals are stored in registers, then data of all 24 registers of the acquisition board in a sampling period are respectively read by the AT96 bus CPU board, and the stable rotational speed value of a
momentum wheel can be obtained by carrying out the arithmetic
processing. The test device and the method have the advantages that the test device can prevent the
electromagnetic interference; the board devices have strong universality and simple maintenance; the momentum wheel pulse acquisition board acquires the data, the bus CPU processes the data, thereby obtaining the stable rotational speed value of the momentum wheel; the rotational speed of the momentum wheel can be precisely calculated, thereby avoiding the errors caused by installation process errors; the test device has
maintainability, replaceability and is compatible with standard common
software, thereby facilitating the
software development; the communication speed is high, thereby ensuring the timeliness of the obtained
calculated data.
