Description
Technical field:
The present invention relates to position, angle sending set, particularly position, a kind of rudder for ship angle sending set.
Background technology:
Rudder for ship instrument is the prerequisite instrument and equipment of all size boats and ships navigated by water on the water, rudder for ship instrument is the information displaying rudder for ship position of foundation position, rudder for ship angle sending set, position, current rudder for ship angle sending set is the link gear being kept synchronous parallel principle by a kind of opposite side of parallelogram, drive device and the rudder for ship synchronous axial system such as such as potential device, Hall element, adjustable condenser, rotary encoder, these devices can produce the numerical value change of magnetic, electricity, pulse etc. when rotating, utilize the changing pattern of these numerical value to draw up the angle of rudder for ship change.
This way exists that transmission distance is little, outside poor anti-interference, problem easy to wear, also exist:
1, even the very accurate link gear done, unavoidable accumulated error and conduction eror, precision is difficult to reach 0.1 degree.
2, these devices are not specially for position, angle sensitive design, numerical value change Linearity imperfect, and very difficult accurate analog goes out the position, change angle of rudder for ship.
3, because these devices are not the data of direct reading angular change, operable digital code information neither be produced, but analog signal is converted into digital signal, not only will affect precision, and the response time that impact is overall.
4, zero-bit adjustment difficulty, although the detection of steamer rudder angle, be substantially not more than 180 degree, but need to determine zero-bit, the existing senser element detected for position, angle, can the rotation of 360 degree, but all can not the detection of 360 degree except rotary encoder, have the blind area of a numerical value, the blind area of this numerical value increases many troubles to the determination of zero-bit.
Chinese patent 2007101713839 proposes a kind of information generator of ship rudder instrument of automatic calibration, the analog information that rudder for ship rotates can be become digital code information and go out.But still can not overcome above-mentioned defect.
Summary of the invention:
The object of the invention is to invent a kind of half direct that rotate together with rudder for ship, directly reading and transmission position, rudder for ship angle change information position, passive semi Direct Laser rudder for ship angle sending set.
The present invention is achieved in that position, passive semi Direct Laser rudder for ship angle sending set is made up of main body and a fitting, main body is by laser recognizer, identification piece, circuit card, device is set, interface, shell and cavity lid composition, shell is fixed on fixing object, laser recognizer, identification piece, circuit card sealing in the enclosure, device is set, laser recognizer, interface is connected with circuit card, identification piece arranges and identifies, mark has plane mark and stereo identification, mark is the numerical value that laser recognizer can identify, numeric representation information, laser recognizer can read the mark on identification piece, the mark that laser recognizer can read by circuit card becomes the format digital code information that can directly use by encoding and decoding and calculating, between fitting be made up of driving link and Passive part, driving link and Passive part there is driving cog,
It is characterized in that: identification piece is fixed on Passive part, driving link is fixed on rudder stock, and it is fixed that laser recognizer is fixed on shell, and the non-perpendicular shape ground of reading-port of laser recognizer is facing to the mark on the identification piece of non-horizontal shape.
Wherein, device and interface are set in the cavity of case surface, arrange above device and interface and have openable cavity lid.

Detailed description of the invention:
With reference to Fig. 1, accompanying drawing 1 is the side elevational cross-section schematic diagram of run-in index practical example.
In figure, fixing object 61 is fixed, and the shell 51 of main body 50 is connected with fixing object 61, and shell 51 is fixed, and it shell 51 is also fixed that laser recognizer 10 is connected to.
Identification piece 20 right and wrong are fixed on the Passive part 32 of a fitting 30 horizontally, so identification piece 20 and Passive part 32 simultaneous action, driving cog 33 is had to engage between Passive part 32 with driving link 31, both are synchronous axial system directly, driving link 31 is connected on rudder stock 60, and when rudder stock 60 rotates time, driving link 31 can rotate equally, Passive part 32 also can synchronous axial system, and identification piece 20 also can equally with rudder stock 60 rotate.
Identification piece 20 arranges N number of mark 21, the reading-port 11 of laser recognizer 10 be non-vertical configuration facing to a mark 21 on identification piece 20, mark 21 has plane mark 22 and stereo identification 23, mark 21 is the numerical value that laser recognizer 10 can read identification, different marks 21 represents different information, and mark 21 comprises position, angle information and check information.
When identification piece 20 rotates, laser recognizer 10 reads the mark 21 different accordingly on identification piece 20 by reading-port 11, the information of reading is passed to circuit card 40 by connection lead 12 by laser recognizer 10.
Circuit card 40 is made up of electronic component 41, circuit card 40, arranges device 70 and interface 46 all in cavity 53, and the top of cavity 53 has cavity lid 52 to seal.
Laser recognizer 10, device 70 is set all is connected with circuit card 40 with interface 46.The information that laser recognizer 10 can read from mark 21 by circuit card 40, encoding and decoding and calculating become the format digital code information that can directly use.
Interface 51 is access power supply and the parts picking out information.
With reference to accompanying drawing 2, accompanying drawing 2 is top cross-sectional view of run-in index practical example.
In figure, driving link 31 is fixed on rudder stock 60, has driving cog 33 to engage between Passive part 32 with driving link 31, and when rudder stock 60 rotates time, Passive part 32 can rotate, so identification piece 20 and rudder stock 60 synchronous axial system equally.
The arrangement of mark 21 on identification piece 20 is the direction of rotating with rudder stock 60 is consistent, and on identification piece 20, the length of mark 21 is greater than the length in laser path of process on identification piece 20 of reading-port 11.
Circuit card 40, arrange device 70 and interface 46 in cavity 53, cavity lid 52, above cavity 53 is, laser recognizer 10, arranges device 70 and is all connected with circuit card 40 with interface 46.
Arrange on device 70 have zero position key 71, hard port arranges key 72, hard starboard arranges the setting parts such as key 73, indicator lamp 74, the function arranging device 70 is the exact location confirming hard port, zero-bit, hard starboard.The number of degrees of the full-helm of various ships are not quite similar, and various ships generally has 35 degree, 45 degree, the 60 degree several forms in left and right.Existing way is independent corresponding separately, can not be general so specification is various, and the present invention can be general.
The process arranged is such: when the diverse location of rudder for ship, confirm by different buttons, such as press hard port to arrange key 72 confirm when rudder for ship hard port, press hard starboard to arrange key 73 confirm when rudder for ship hard starboard, press zero position key 71 to confirm when rudder for ship zero-bit, when setting, indicator lamp 74 can carry out operation indicating.
The information of reading is passed to circuit card 40 by connection lead 12 by laser recognizer 10, and by accepting circuit 42, decoding circuit 43, computing circuit 44, transtation mission circuit 45, interface 46 becomes the format digital code information that can directly use and pass.
