Problems solved by technology
The inertial navigation system based on gyroscope and adding meter can realize the measurement of high-precision dynamic accuracy, but it is expensive and difficult to be widely used; while other inclination sensors are static sensors, which are suitable for static testing. In dynamic testing, their accuracy It can only reach dozens of times of the static error, the measurement accuracy is low, and it is difficult to meet the needs of engineering measurement

Embodiment
[0018] When a warship is operating at sea, it is necessary to level the precision instruments on the warship, that is, it is necessary to measure the dynamic inclination of the precision instruments relative to the stationary horizontal ground. During the measurement, the present invention is fixed on the instrument that needs to be leveled, and the dynamic inclination angle of the swing of the weight 1 in a plane to be measured is measured , because the weight 1 cannot stop at the plumb position, the processor 5 will automatically convert the amplitude of the photoelectric code disc 4 in the positive and negative directions at a certain angle into the instrument relative to the stationary horizontal ground in the plane to be measured. Dynamic inclination. During application, the output end of the processor 5 of the present invention is connected with the control system of the instrument, and then converted into the leveling angle of the instrument in the plane to be measured...
