Abstract
The invention discloses a display screen system for a cabin of a crane and other heavy-duty machinery. The display screen system comprises a display screen, wherein an anti-reflective membrane is adhered on the surface of the display screen, or a sensor for monitoring an environment illumination condition and a feedback control system of the sensor are installed on the display screen, or an anti-reflective membrane is adhered on the surface of the display screen and simultaneously a sensor for monitoring the environment illumination condition and a feedback control system of the sensor are installed on the display screen. In the display screen system for the cabin of the crane and other heavy-duty machinery, the sensor is adopted for monitoring the environment illumination condition, the luminance of the display screen is adjusted dynamically according to external light, and the optical anti-reflective membrane is further adopted for eliminating light and surrounding sights reflected by the surface of the display screen, therefore, an optimal observation effect can be obtained, and operators of the crane and the other heavy-duty machinery can observe the picture of the display screen clearly so that influence of the environmental light and sights on the safety of operation can be avoided.
Description
Technical field
The present invention relates to the display screen technology field, specially refer to crane and other heavy-duty machinery passenger cabins are used display screen system.
Background technology
In recent years, flourish along with China's capital construction, the market demand of heavy-duty machineries such as crane is increasing, and heavy-duty machineries such as crane are as the infrastructure device of heavy industry, and China enterprise must grasp its core technology and have independent intellectual property right.
The display screen that uses in crane and other heavy-duty machinery passenger cabins is mainly used in operating personnel's watch-dog running status and building site environment, belongs to the important appurtenances of crane and other heavy-duty machineries.Mostly the display screen that uses in present crane and other heavy-duty machineries, its passenger cabin is the common display screen, and the characteristics of this display screen are that brightness is lower, and mostly center position brightness is below the 500nit, only is applicable to indoor use.When under outdoor bright light environments, using, because the scenery around the display screen is brighter, the observer can can't see the picture on the screen clearly; In addition, when outdoor application, the glass plate of display screen surface can reflect such as extraneous lights such as sunlight, the brightness meeting of reflection ray near in addition surpass the brightness of display frame, and glass pane surface reflected outside scenery also can influence observer's use.The operation of equipment that these drawbacks not only influence is experienced, even might influence handling safety.
For addressing this problem, some mechanical manufacturers have strengthened the driving power of display screen to propose brightness, and still there is certain defective in this method.The light conditions of field operation environment is changeable, and for example fine day and the brightness under the cloudy day can differ more than ten times, even down fine; Brightness under sunlight direct projection and the shade also can differ tens times, because brightness of display screen is non-adjustable, is provided with low; Then under high-brightness environment, still be difficult to watch; Be provided with too highly, then when the low-light level environment can make the operator observe on every side scenery, produce dazzling sense, influence handling safety then; On the other hand, the light or the outside scenery of the reflection of display screen surface glass plate still can influence the observer, can not eliminate this influence fully even increase output brightness.
Summary of the invention
The technical matters that the present invention will solve provides a kind of display screen system applicable to crane and other heavy-duty machinery passenger cabins.
The technical scheme that adopts for solving the problems of the technologies described above: a kind of crane and other heavy-duty machinery passenger cabins are used display screen system; Include display screen, it is characterized in that: said display screen posts anti-anti-film or the sensor that is used for the monitoring of environmental light conditions is installed and feedback control system or sensor and the feedback control system thereof that is used for the monitoring of environmental light conditions is installed when screen surface is posted anti-anti-film in screen surface.
Can be preferably, said anti-anti-film is a kind of optical thin film that reflectivity improves transmissivity that reduces.
Can be preferably, said sensor is illuminance transducer or luminance sensor.
On the basis of the above, said sensor is provided with a plurality of, be arranged at around the display screen or operator's console on.
Wherein display screen adopts cold-cathode tube liquid crystal display backlight or LED backlight liquid crystal display or organic light-emitting diode (OLED) display screen.
Adopt the beneficial effect that the present invention brought: display screen posts and reduces the anti-anti-film that reflectivity improves transmissivity; The anti-anti-film of this optics can be eliminated because display screen surface glass plate reflection ray is difficult with the observation that scenery on every side causes; For display screen itself, more rays is transmitted into and can improves display screen output brightness.And the sensor that is used for the monitoring of environmental light conditions and the display screen of feedback control system thereof have been installed; Then according to sensor monitors to the weighted mean of the ambient lighting data that arrive of ambient lighting data or a plurality of sensor monitors, adjust the output brightness of display screen through feedback control system.The present invention has used the sensor that is used for the monitoring of environmental light conditions; According to extraneous light dynamic adjustments brightness of display screen; Also used the anti-anti-film of optics to eliminate the light of display screen surface reflection and scenery on every side; Can obtain best observing effect, make the operator of crane and other heavy-duty machineries can clearly observe the picture of display screen, make its around being unlikely to receive light and scenery and have influence on handling safety.
