Abstract
The invention discloses a rudder angle indicator with video and electronic compass display, which comprises a rudder angle transmitter and a touch screen display. A potentiometer, a temperature sensor, a video image acquisition module, a singlechip and a data acquisition module are arranged in the rudder angle transmitter. With the adoption of the rudder angle indicator, a pattern of a pointer-type rudder angle meter can be directly simulated on a display screen by using an advanced touch type display screen; and the rudder angle indicator has the functions of real-time video image display in a steering engine room, temperature display and the ship direction display by an electronic compass.
Description
Technical field
The present invention relates to a kind of helm indicator, particularly a kind of helm indicator shown with video and radio compass.
Background technology
Helm indicator is used to rudder blade rotation direction when indicating vessel motion and the very important instrument of angle, is usually arranged on Duo Tai dead ahead, ship-handling cabin.According to existing product, pointer-type, digital and numerical indexes formula three class can be divided into by display mode.
On existing market in helm indicator, according to the difference of the angular transducer that signalling generator adopts; Be divided into again common carbon brush potentiometer type helm indicator, inductance type helm indicator, selsyn formula helm indicator and digital coding type helm indicator etc.
1), inductance type helm indicator is comparatively large owing to affecting by external factor such as hull magnetic fields, and installation and maintenance difficulty has been eliminated greatly;
2), common carbon brush potentiometer type helm indicator is lower due to cost, is still equipped in a large number on part ship for civil use.But to be subject in moisture, salt fog, steering gear flat the factor impacts such as temperature due to common carbon brush potentiometer, often to occur the phenomenons such as display is malfunctioning, pointer drift, badly influence navigation safety.
3), selsyn formula helm indicator and digital coding type helm indicator etc. due to technical sophistication, be vulnerable to ship hull vibration impact and use, and if precision is higher, cost is higher, except some senior yachts adopt on a small quantity, trace almost be can't see in market.
Summary of the invention
In order to overcome the drawback that above-mentioned helm indicator exists, the invention provides a kind of helm indicator shown with video and radio compass, adopting advanced touching display screen, directly simulate the pattern of pointer rudder angle meter on a display screen.There is the function in the display of steering gear flat real time video image, Temperature displaying, radio compass display hull direction.
Above-mentioned purpose of the present invention is realized by such technical scheme: a kind of helm indicator shown with video and radio compass, comprise rudder angle signalling generator, touch-screen display, be provided with potentiometer, temperature sensor, video image acquisition module and single-chip microcomputer and data acquisition module in described rudder angle signalling generator, described rudder angle signalling generator is connected to touch-screen display by telecommunication cable.
Described rudder angle signalling generator is all-sealed structure.
Described potentiometer is high accuracy conductive plastic potentiometer.
Described touch-screen display is provided with vision signal viewing area, rudder angle meter district, steering gear flat Temperature displaying district, radio compass; Vision signal viewing area is for demonstrating the real time video image signal in steering gear flat; Rudder angle meter district is for simulating and accurately demonstrating the real-time angular of rudder angle; Steering gear flat Temperature displaying district is used for demonstrating real time temperature in steering gear flat; The orientation of radio compass display hull.
A kind of beneficial effect of helm indicator with video and radio compass display of the present invention is as follows:
1), adopt advanced touching display screen, directly simulate the pattern of pointer rudder angle meter on a display screen;
2), adopt high accuracy conductive plastic potentiometer, improve real-time rudder angle precision;
3) detection and the display of steering gear flat temperature, is added;
4) the radio compass function of this ship position, is added;
5) real time video image collect and transmit and Presentation Function in steering gear flat, is added;
And on above function equal integrative display touching display screen.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is apparatus of the present invention structural representations.
Embodiment
As shown in Figure 1, a kind of helm indicator shown with video and radio compass, comprise rudder angle signalling generator 7, touch-screen display 8, be provided with potentiometer 2, temperature sensor 3, video image acquisition module 4 and single-chip microcomputer and data acquisition module 6 in described rudder angle signalling generator 7, described rudder angle signalling generator 7 connects touch-screen display 8.Described rudder angle signalling generator 7 is connected to touch-screen display 8 by telecommunication cable 9.Described rudder angle signalling generator 7 is all-sealed structure.Described potentiometer 2 is high accuracy conductive plastic potentiometer.
Single-chip microcomputer and data acquisition module 6 by high accuracy conductive plastic potentiometer Real-time Collection steering wheel angle, gather temperature in rudder angle cabin to temperature sensor 3, gather real time video image in rudder angle cabin to video frequency pick-up head 5, unifiedly carry out coded treatment and to be sent on touch-screen display 8 by network service cable and to show in real time in real time.
Telecommunication cable 9 adopts 485 interfaces to transmit rudder angle and temperature data; Adopt RJ45 network delivery vedio data.
In ship running, the rotation of steering wheel 1 is directly delivered to potentiometer 2, cause the change of potentiometer 2 resistance value, after single-chip microcomputer and data acquisition module 6 determine orientation and angle, convert digital signal in real time and encode, be transferred on touch-screen display 8 by 485 interfaces of telecommunication cable 9, touch-screen display 8 simulates the real-time angular that pointer instrument panel also accurately demonstrates rudder angle.Single-chip microcomputer and data acquisition module 6 are by gathering the temperature sensor 3 be located in steering gear flat, temperature in Real-time Collection steering gear flat, and be transferred on touch-screen display 8 by 485 interfaces of telecommunication cable 9, touch-screen display 8 demonstrates the real time temperature in steering gear flat.
Simultaneously, single-chip microcomputer and data acquisition module 6 are by gathering the video image acquisition module 4 be located in steering gear flat, video image in Real-time Collection steering gear flat, and be transferred on touch-screen display 8 by the RJ45 interface of telecommunication cable 9, touch-screen display 8 demonstrates the real time video image in steering gear flat.
Be provided with radio compass in touch-screen display 8, automatically can remove hull interference, and on the touch-screen of touch-screen display 8, demonstrate the orientation of current hull in real time.
The touch-screen of touch-screen display 8 is provided with the touch button of brightness regulation, can regulate the brightness of the touch-screen of touch-screen display 8.
The touch-screen of touch-screen display 8 is provided with the touch button of rudder angle zero position, after steering wheel is installed, and can the dead-center position of initialization helm indicator.Arrange button and be provided with password, the user that must have proper password just can be arranged.
