Specific embodiment
The streamlined compass can realize azimuthal measurement, mileage measurement, on the spot pitch angle measurement, the work(such as Distance estimation
Energy.
1st, azimuthal measurement mechanism
As Fig. 3 azimuthal measuremenies mechanism includes compass combination 3, foresight breach 31, aims at breach 311 and reviews mirror 36.To survey
Amount azimuth, compass compass combination two kinds of scales of 39 degree of being carved with and mil, is respectively suitable for 0 °～360 ° and 0～60-00 is close
The measure of the two kinds of nominal values in position, inner ring scale unit are 360 °, and at intervals of 2 °, outer ring scale unit is 60-00 mils to groove, between groove
It is divided into 0-20 mils.Hand-held compass is launched into 180 °, first calibrate magnetic sit drift angle, then by illuminator 6 be folded to observer into
It is 45 °, simple eye by aiming at the alignment run-home between breach 311 and foresight breach 31；Finger gyrocompass combination 3,
Make the MN red lines of 3 bottoms of compass combination parallel with the magnetic needle in magnetic needle group 315, and magnetic meridian（MN lines）Red arrow 37 and magnetic
Magnetic needle the North in pin group 315 is in the same direction；Through illuminator 36, the mil value or the number of degrees read at red marker line 316 is
The value at measured target azimuth.
2nd, mileage measuring mechanism
As Fig. 3,4, mileage measuring mechanism includes mileage wheel 34, mileometer indicator 18, mileometer board 19.On mileometer board
Carve 1:100000；1:50000；1:25000 3 kinds of scale division lines, unit is kilometer.Certainty of measurement：.Expansion refers to north
Pin opens mileage wheel protective cover 33 into 180 °, and finger stirs mileage wheel 34, make mileometer indicator 318 move clockwise to it is red
Line overlaps, to eliminate backlash；Mileage wheel 4 is parked in into map starting point, and makes the vertical map of white line above mileage wheel 34；
（Note：Mileage wheel 34 can only be rolled, it is impossible to slide；Mileometer indicator 18 should be rotationally clockwise）；Mileage wheel 34 along
Course rolls forward on map reads mileometer indicator from mileometer board 19 according to corresponding map ratio to impact point
Numerical value indicated by 18 is traveling milimeter number.
3rd, pitch angle measurement mechanism
Such as Fig. 3 pitch angle measurements mechanism includes the groups such as pitching pendulum 314, the pitching dial plate looked squarely in mirror 36, compass combination 3
Into.Pitch angle measurement is realized by self gravitation by pitching pendulum 314.Pitching pendulum scale value scope be ± 90 °, groove at intervals of
2°.Pitch angle measurement on the spot between pitch angle measurement, standpoint and target and remote landform pitch angle measurement can be divided into.Survey
Need to launch before amount compass into 180 °, open mileage wheel protective cover 33, gyrocompass combination 3 makes compass combine on 3 watch faces
270 °（W）Line is overlapped with red index line 316.Then left hand holds compass, makes grade rod face 38 domatic against measured object, bows
Face upward pendulum 314 the as pitching on the spot of 314 red arrow indication scales is put in pitching in vertically downward state, now compass combination 3
Angle
4th, Distance estimation mechanism on the spot
As having one group of groove to be apart from assessment line at the foresight breach 31 of Fig. 3 caps, it is known that observed object length, utilize
Apart from assessment line, the distance of target and observation station can be speculated.Hand-held compass, visually by aiming at breach 311 and foresight breach
Between alignment run-home, the groove lattice number that target is accounted at foresight breach 31 be n, it is known that target length is B（m）, mesh
Subject distance is L（m）.Then target range is 100 times of target length and lattice number ratio shared by target, and formula is 。
The precision of Distance estimation is not high on the spot, and because human eye vision is limited, estimation distance is typically within 400m
Preferably, and distance it is more remote, its error is bigger.
5th, compass combination
Compass rigidity in the compass combination as described in Fig. 2 present invention is directed to is bad, and the problem for easily deforming upon is employed
Below scheme is solved：1. from the PMMA-021 injected plastics materials that elastic modelling quantity is high, strengthen adaptability of the compass to environment；②
Compass parts geometry is improved, strengthens compass structure rigidity；3. increase the thickness of compass bottom group and compass lid, improve compass
Non-deformability.
