Multi-point interpolation linear control system of grating spectrometer

The multi-point interpolation linear control system comprises a motor (1), a Hall sensor (2), a grating shaft swing rod (3), a grating (4), a ball head (5), a lead screw (6), a Hall group (7), a sliding block (8) and magnetic steel (9), the motor (1) drives the lead screw (6), the sliding block (8) on the lead screw drives the grating shaft swing rod (3) through the ball head (5), and the grating shaft swing rod (3) is connected with the grating (4) to drive the grating to rotate. Wherein the motor (1) rotates to drive a motor rotating shaft to detect the magnetic steel (9), and the Hall sensor (2) monitors the running state of the motor (1); the Hall group (7) is parallel to the lead screw (6) when the position of the sliding block (8) is monitored, and the lead screw (6) is divided into a plurality of sections on the stroke through the Hall group (7) when the position of the sliding block (8) is monitored. 本发明公开了一种光栅光谱仪多点插值线性控制系统,包括：电机(1)、霍尔传感器(2)、光栅轴摆杆(3)、光栅(4)、球头(5)、丝杠(6)、霍尔组(7)、滑块(8)和磁钢(9)；所述电机(1)驱动所述丝杠(
