Description
Technical field
The utility model relates to touch-screen, specifically a kind of mine explosion-suppression touch-screen.
Background technology
In order to guarantee the safety in production in colliery, the electrical equipment that is applied under the coal mine must satisfy the flame proof requirement.With regard to the man-machine interface under being applied at present coal mine, mainly comprise push button man-machine interface, keyboard-type man-machine interface, infrared remote control formula man-machine interface.Wherein, the mode of push button man-machine interface input data is comparatively clumsy, causes data input efficiency low.Keyboard-type man-machine interface or infrared remote control formula man-machine interface need up and down operation when carrying out the screen cursor location, cause equally data input efficiency low.Compared to above-mentioned various man-machine interfaces, the touch-screen type man-machine interface has advantages of that data input efficiency is high.Yet existing touch-screen type man-machine interface is limit owing to self structure, and is not suitable under the coal mine.Particularly: one, existing touch-screen type man-machine interface be not owing to possessing explosion insulation performance, thereby in a single day it discharge and recharge, and just easily causes and gas explosion in underground coal mines cause potential safety hazard.Its two because the colliery subsurface environment is abominable, the touch-screen type man-machine interface very easily by scratch, damage, causes its application cost too high in the down-hole.Based on this, be necessary to invent a kind of brand-new touch-screen type man-machine interface, be not suitable for problem under the coal mine to solve existing touch-screen type man-machine interface.
Summary of the invention
The utility model is not suitable for problem under the coal mine in order to solve existing touch-screen type man-machine interface, and a kind of mine explosion-suppression touch-screen is provided.
The utility model is to adopt following technical scheme to realize: the mine explosion-suppression touch-screen comprises acoustic wave touching screen, water proof and dust proof window and flame proof pad; Described acoustic wave touching screen comprises screen body of touch screen, touch screen controller and communication link wiring; Described water proof and dust proof window comprises water proof and dust proof window window and window gripping mechanism; Wherein, screen body of touch screen, flame proof pad, water proof and dust proof window window stacked arrangement from top to bottom; Leave the gap between the front of flame proof pad and the back side of screen body of touch screen, this gap consists of the first explosion suppresion surface; Leave the gap between the front of the back side of flame proof pad and water proof and dust proof window window, this gap consists of the second explosion suppresion surface; The front edge of water proof and dust proof window window is fixed by the dorsal edge of window gripping mechanism and screen body of touch screen; The signal end of screen body of touch screen is connected with the signal end of touch screen controller by the communication link wiring.
During work, the user inputs data by screen body of touch screen, and the data of inputting transfer to touch screen controller through the communication link wiring and process.In this process, the first explosion suppresion surface, the second explosion suppresion surface, flame proof pad can stop the spark of screen body of touch screen inside to arrive the screen body of touch screen outside gas that ignites jointly, thereby avoid causing when screen body of touch screen is discharged and recharged gas explosion.The water proof and dust proof window can prevent effectively that then screen body of touch screen is subject to the impact of coal dust under the coal mine, moisture or water, and prevents that screen body of touch screen is by scratch, damage.Based on said process, to compare with existing touch-screen type man-machine interface, mine explosion-suppression touch-screen described in the utility model possesses following advantage: one, possessed explosion insulation performance, can not cause gas explosion in underground coal mines being applied to coal mine lower time.Its two, can by scratch, damage, not reduce thus application cost being applied to coal mine lower time.In sum, mine explosion-suppression touch-screen described in the utility model efficiently solves existing touch-screen type man-machine interface and is not suitable for problem under the coal mine.
Further, be connected with sealing strip between the dorsal edge of the front edge of water proof and dust proof window window and screen body of touch screen.During work, sealing strip can make the combination between water proof and dust proof window and the acoustic wave touching screen tightr, further strengthens the water proof and dust proof ability.
Further, the signal end of touch screen controller is connected with USB interface.During work, the signal end of touch screen controller can be connected with outside industrial control computer by USB interface.Data in the touch screen controller can in time feed back to outside industrial control computer by USB interface, and touch screen controller can in time receive from the order of outside industrial control computer by USB interface and also be carried out simultaneously.
The utility model efficiently solves existing touch-screen type man-machine interface and is not suitable for problem under the coal mine, is applicable under the coal mine.
