Problems solved by technology

However, due to the long history and the limitations of the control ideas and device technology level at that time, it has been unable to meet the requirements of marine gravity measurement. At the same time, the electrical control parts of many domestic imported German gravimeters have been damaged.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0019] 1. The working principle of the GSS-2 gravimeter consists of figure 1 It can be seen that when the torque generated by the gravity on the pendulum G is balanced with the torque of the fulcrum spring s, the pendulum G remains in a horizontal position. At this time, the photocells V located at the upper and lower ends of the pendulum M 1 , V 2 , because the illuminance received by the bulb L is the same, the synthesized output voltage V is zero, which is the initial state of the gravimeter. Between the pendulum M and the fulcrum O, there is also an upward measurement spring S 1 and lower spring S 2 , S 1 and S 2 Both the elongation and compression of will produce additional torque acting on the pendulum G. S 1 It is manually adjusted to adjust the measurement range of the gravimeter; S 2 The motor E is regulated by the gravimeter closed-loop, and its elongation or compressi...

Abstract

A control device of ocean gravimeter which is for modifying the ocean gravimeter of Germany GSS-2 type contains the chosed loop self adjusting system comhined with the ocean gravimeter in original shape. Its low speed operating circuit of synchro is composed of CPU stepping calculation unit, output circuit of motor and existing position memory unit of the moter.

Description

technical field [0001] The invention relates to a marine gravimeter, in particular to a control device for the marine gravimeter. Background technique [0002] The monitoring and research of the temporal and spatial changes of the ocean gravity field is undoubtedly an extremely important content in the study of Earth's gravity. At the same time, due to the abundant reserves of marine resources (such as oil), marine gravity measurement has become a more effective means of geophysical exploration for human beings. Although satellite gravity measurement can monitor ocean gravity using space technology, the determination of satellite orbit parameters still needs to be based on surface gravity measurement data. Therefore, the use of marine gravimeters to measure gravity on the sea surface is still an indispensable means for marine gravity research and marine geophysical exploration. Since the sea surface gravity measurement is carried out in a dynamic environment, the comprehen...
