Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of horizontal positioning, and particularly relates to a self-stabilizing movable chassis. BACKGROUND

[0002] During the debugging process of the magnetic demodulation board, the output signals of the three-axis magnetic sensor are collected first, and then the zero adjustment and amplitude adjustment operations are sequentially performed on each axis to finally achieve the debugging goal of accurate output signal values and symmetrical output of each-axis magnetic sensor. The key technical requirements are: the arrow of the strapdown magnetic sensor needs to be accurately pointed to the north direction, and when the dial is in the zero position after the leveling of the non-magnetic three-axis turntable is completed, the magnetic output signal value of the certain-axis magnetic sensor needs to reach the maximum value The current debugging operation has two paths, neither of which can efficiently meet the above requirements: the first path is to rotate the turntable baseplate for one revolution after the strapdown magnetic sensor arrow is north and the non-magnetic three-axis turntable is leveled, and then to observe and locate the maximum value of the certain-axis magnetic sensor output signal, but the position often has a slight deviation from the dial zero position; the second path is to directly move the non-magnetic three-axis turntable legs, and stop moving when the certain-axis magnetic sensor output signal reaches the maximum value, at which time the positioning scale can be aligned with the dial zero position, but the horizontal bubble will deviate from the center due to the movement of the legs, and the leveling operation needs to be performed again. The results of the above two operations are difficult to meet the debugging requirements, and must be repeated multiple times, resulting in a significant reduction in debugging efficiency Further analysis shows that the original debugging scheme has three major defects: first, the alignment operation is repetitive, significantly prolonging the debugging period and reducing efficiency; second, directly moving the turntable legs can damage the original structure of the non-magnetic three-axis turntable, affecting the completeness of the equipment; third, although the dial can be aligned when it is not at zero, manual calculation of the reverse scale is required, which increases the risk of human reading errors, raises the requirements for the calculation ability of the operator, and increases the operation complexity. Therefore, it is necessary to improve the above problems. SUMMARY
