Problems solved by technology

[0007] The present invention provides a navigation sextant design theory and method based on perpendicularity determination, one of which aims to solve the existing navigation sextant problem with a day observation mirror, a first photoresistor, a second photoresistor and a micro motor. When the submeter is in use, daytime observation requires the user to look directly at the refracted light with the eyes, and long-term use is very harmful to the eyes; another purpose is to solve the problem of nighttime observation when the existing navigation sextant is in use. It is difficult to find a water antenna for reference, resulting in too long observation time and excessive limitations in use, so as to achieve the effect of fast observation at night

Embodiment 1

[0036] First aspect, such as Figure 1-5 As shown, the present invention provides a nautical sextant design device based on verticality judgment, comprising a sextant main body 1, a moving mirror pointer 2 and a fixed mirror assembly 4, and the interior of the sextant main body 1 is provided with a moving mirror pointer 2. One side of the moving mirror pointer 2 is provided with a fixed mirror assembly 4, and the inside of the fixed mirror assembly 4 is provided with a night viewing mirror 9, and one side of the night viewing mirror 9 is fixedly connected with a daytime viewing mirror 10, and the side of the night viewing mirror 9 The back is fixedly connected with a horizontal ball 13, the top of the inner wall of the horizontal ball 13 is fixedly connected with a vertical line 15, and one side of the night observation mirror 9 is fixedly connected with a first photoresistor 11, and a second photoresistor is arranged below the first photoresistor 11. 12. The back side of the ...

Embodiment 2

[0038] like Figure 1-5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the front of the sextant main body 1 is fixedly connected with an indicating scale 5, and the back of the sextant main body 1 is fixedly connected with a level adjustment assembly 3 , the left side of the horizontal adjustment assembly 3 is fixedly connected with the control assembly 6 , the right side of the horizontal adjustment assembly 3 is fixedly connected with the buzzer assembly 8 , and the right side of the sextant main body 1 is provided with a telescope 7 .

[0039] The working principle of the nautical sextant design theory and method based on verticality determination will be described in detail below.

[0040] like Figure 1-5 As shown, in the daytime, the horizontal position of the sextant body 1 is automatically calibrated by using the external power supply level adjustment assembly 3, and the daytime measurement is performed. The mo...

Embodiment 3

[0042] In the second aspect, the present invention provides a technical solution: a theory and method for designing a nautical sextant based on verticality determination. The main steps of the design theory and method for a navigational sextant based on verticality determination are as follows:

[0043] Step 1: Instrument calibration;

[0044] Step 2: Data measurement.

[0045] The instrument calibration in step 1 includes the following steps:

[0046]A1: During the day, the horizontal position of the sextant body 1 is automatically calibrated by using the external power supply level adjustment component 3;

[0047] A2: At night, hold the main body of the sextant 1, and use the characteristic that the pituitary gland 17 is always vertically drooping, and use the horizontal bar of the horizontal luminous parallel bar 16 as the water antenna.

[0048] Data measurement in step two includes the following steps:

[0049] B1: Daytime measurement, the moving mirror pointer 2 recei...

Abstract

The invention discloses a navigation sextant design theory and method based on perpendicularity judgment, and relates to the technical field of navigation measurement, the navigation sextant design theory and method comprises a sextant main body, a movable mirror pointer and a fixed mirror assembly, the movable mirror pointer is arranged in the sextant main body, and the fixed mirror assembly is arranged on one side of the movable mirror pointer; a night observation mirror is arranged in the fixed mirror assembly, a daytime observation mirror is fixedly connected to one side of the night observation mirror, and a horizontal ball is fixedly connected to the back face of the night observation mirror. Through the daytime observation mirror, the first photoresistor, the second photoresistor, the micro motor, the horizontal ball, the vertical line, the vertical body and the transverse noctilucent parallel rod, the problem that when an existing marine sextant is used, a user needs to directly see refracted light with eyes during daytime observation; the problems that the observation time is too long and the use limitation is too large due to the fact that the long-time use causes great damage to eyes and the water antenna is difficult to find for reference during night observation are solved.

Description

technical field [0001] The invention relates to the technical field of navigation measurement, in particular to a design theory and method for a navigation sextant based on verticality determination. Background technique [0002] A sextant is an optical instrument used to measure the angle between two distant targets. It is usually used to measure the angle between the sun or other celestial bodies and the sea level or horizon at a certain moment, so as to quickly know the latitude and longitude of the position of the ship or aircraft. [0003] At present, despite the continuous development of modern navigation technology, the nautical sextant has always been used as one of the guarantee means for ships and ship navigation due to its independence and high reliability, and there is no better equipment to replace it. But the existing navigation sextant also has certain problems in use. [0004] There are following problems at prior art: [0005] 1. When the existing nautica...
