Rhumb self-operated measuring unit simple structure, it is easy to operate, control button can respectively with " clicking ", " double-click " or
" length is pressed " three kinds of different push-botton operations realize " measurement ", " calibration " or " deletion " three kinds of function controls.
The electric power system 9 is target bearing sensor 3, information processing system 4, display unit 5, communication interface 6 and control
The unification power supply of system processed 8, electric power system 9 has rechargeable function.
Fig. 2 is the angle measuring principle figure of rhumb self-operated measuring unit shown in Fig. 1, in figure ---
B1--- true bearing, on the basis of geographical north；
B2--- compass bearing, on the basis of compass north；
B3--- microelectromechanicgyroscope gyroscope orientation, on the basis of microelectromechanicgyroscope gyroscope north；
B4--- magnetic azimuth, on the basis of magnetic north；
△21--- compass error, △21=B1-B2；
△23--- reference difference, △23=B3-B2
B3、B4Can be in real time given by the target bearing sensor 3.
During observation positioning, the long power switch " ON/OFF " by electric power system 9 is started shooting, and rhumb self-operated measuring unit is opened
Beginning work.Initialize first, host computer application system 7 is carried out initially by communication interface 6 to rhumb self-operated measuring unit
Change parameter setting, including：Time setting, compass error △21Setting and pattern setting.Pattern setting is divided into " compass north reference mode "
" celestial body azimuth reference mode ", by calculated azimuth of celestial body value BtDetermine, Bt=0 ° is " compass north reference mode ", Bt≠ 0 ° is
" celestial body azimuth reference mode ", system default pattern is " compass north reference mode ", and after the completion of initialization, rhumb is surveyed automatically
Amount device is automatically into corresponding mode of operation.
" compass north reference mode " workflow is as follows ---
Step 1:Determine " reference difference "." reference difference " is the poor △ of compass benchmark and microelectromechanicgyroscope gyroscope benchmark23.Assay method
It is：By manipulating 0 ° or 180 ° that optical azimuth device 2 aims at nearby compass circle 1, control button, information processing system are double-clicked
4 are measured to " reference difference " automatically.As a example by aim at 0 ° of compass circle：Optical azimuth device is rotated, compass circle is aimed at
When 0 °, the control button of control system 8 is double-clicked, now, information processing system 4 is according to magnetic north reference bearing information B40 ° of size
≤B4≤ 90 ° or 270 °≤B4≤ 360 °, it is 0 ° that automatic decision goes out be aligned just now, then according to formula △23=0 ° of-B3=-B3
Calculate reference difference △23, and minute and reference difference △23Together record is preserved, while showing B in real time in display unit 51
=B3+△23+△21, wherein △21For system initialization when the compass error that sets.Hereafter system formally enters observation positioning states；
Step 2：Start observation.As the observation landmark fix of traditional rhumb, during 2 run-home of optical azimuth device,
The control button of control system 8 is clicked, that is, completes a target bearing observation.Now, information processing system 4 records sight simultaneously
Survey time and B1, B1=B3+△23+△21(needing the drift compensation for carrying out microelectromechanicgyroscope gyroscope), observation data (time, orientation)
It is sent to display unit 5 to show and preserve.
Complete after single target bearing determines, the rhumb self-operated measuring unit is automatically into observing shape next time
State, waits and aims at determination.It is reciprocal successively, until observation terminates.If it find that this observation error is larger, can grow by control system
The control button of system 8, information processing system 4 will delete this observed result.
Step 3：Upload observed result.At the end of observation, host computer application system 7 can read sieve by communication interface 6
The observation information of classical prescription level auto measurer storage, calculates positioning result automatically.
Step 4：At the end of positioning, the long power switch " ON/OFF " by electric power system 9 shuts down.
As compass error △21When insincere, the utility model rhumb self-operated measuring unit can also be operated in " celestial body side
Position reference mode ".When the modular system is initialized, in addition to the time sets, the computer azimuth B of observation celestial body is also sett(this
In, observing the computer azimuth of celestial body can set in advance, be because that celestial body azimuth is varied less in the range of certain hour), it is full
Sufficient Bt≠ 0 °, while by compass error △21Zero setting.Under this pattern, it is necessary to redeterminate compass error △ using celestial body21.Determination step
It is as follows ---
The first step：Determine reference difference △23.Assay method is the same, and this is sentenced as a example by 180 ° of compass circle of aiming：Rotate light
Azimuth device is learned, when aiming at 180 ° of compass circle, the control button of control system 8, now, the basis of information processing system 4 is double-clicked
Magnetic north reference bearing information B490 °≤B of size4It is 180 ° that≤270 ° of automatic decisions go out be aligned just now, then according to formula
△23=180 ° of-B3Calculate reference difference △23, and minute and reference difference △23Together record is preserved, while single showing
Unit 5 shows in real time B2=B3+△23。
Second step：Compass error by celo-observation.Optical azimuth device is rotated, when optical azimuth device 2 aims at celestial body, control system is clicked
8 control button, as normal observation target bearing, you can complete automatically determining for compass error by celo-observation.Now, B1=
Bt, information processing system 4 is according to △21=B1-B2=Bt-(B3+△23) calculate compass error △21, then observation time and sieve
Jing differs from △21It is stored in respective memory unit；Simultaneously by BtValue zero, cancel " celestial body azimuth reference mode "；Further B1
=B3+△23+△21(needing the drift compensation for carrying out microelectromechanicgyroscope gyroscope) is sent in real time the Dynamic Announce of display unit 5, and system is again
Return to " compass north reference mode ", following steps are omited.
It should be noted that：The compass error △ of " celestial body azimuth reference mode "21Determine, by system according to BtValue enter automatically
Row judge, for survey person, compared to " compass north reference mode ", except Initialize installation is different in addition to, remaining operation with
" compass north reference mode " is identical, and such design is entirely in order to user is easy to use.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
It is any to belong to those skilled in the art in the technical scope that the utility model is disclosed in this, the change that can be readily occurred in
Change or replace, all should cover within protection domain of the present utility model.
