Abstract
The utility model discloses a device for controlling the on/off of a screen, and the device is disposed on an industrial computer. The device comprises a controller, and a key single-chip microcomputer platelet which is connected with the controller. The key single-chip microcomputer platelet comprises a backlight control module and a touch-screen touch control module. The backlight control module is connected with a backlight switch of a screen. The touch-screen touch control module is connected with the touch controller of the screen. According to the utility model, the screen of the industrial computer and the backlight module of the touch screen can be manually switched off/on, thereby enabling the industrial computer to operate normally in the condition of no display. Meanwhile, the backlight and the touch function of the screen can be switched off, thereby enabling the service life of the screen to be prolonged and preventing the touch screen from misoperation.
Description
Technical field
The utility model relates to the screen control technical field of industrial computer, specifically a kind of screen on-off control device being arranged on industrial computer.
Background technology
Conventional computer does not have screen backlight and touch-screen closing function, part computing machine has screen closing function but is not screen backlight closing function, it determines it is to wait again to start while showing, computing machine is reading displayed device information and occur automatic adjustment again, make display screen there will be the shake while adjusting, while also just making to recover display screen, cannot normally inspect displaying contents, simultaneously, conventional display screen, even if closed LCDs, but do not close touch control function, under blank screen state, can also be touched and produce danger.
Utility model content
The utility model, for above shortcomings in prior art, provides a kind of screen on-off control device being arranged on industrial computer.
The utility model is achieved through the following technical solutions.
A kind of screen on-off control device, be arranged on industrial computer, the button single-chip microcomputer platelet that comprises controller and be connected with controller, described button single-chip microcomputer platelet comprises: backlight control module and touch-screen contact control module, described backlight control module is connected with the backlight switch of industrial computer screen, and described touch-screen contact control module is connected with the touch controller of industrial computer screen.
Described controller is arranged on the panel of industrial computer.
Described controller is for controlling button.
Described button single-chip microcomputer platelet is embedded structure.
Described backlight control module is connected with the backlight switch circuit of screen or wireless telecommunications connect.
Described touch-screen contact control module is connected with the touch controller circuit of screen or wireless telecommunications connect.
Described touch controller is touch-screen USB controller.
During work, controlling button is connected with embedded button single-chip microcomputer platelet, after industrial computer system energising, button single-chip microcomputer platelet is in default conditions, be display screen and the touch-screen normal operation of industrial computer, control button on panel presses, button single-chip microcomputer platelet sends two modules and sends at the same time or separately instruction, the instruction that backlight control module sends is the backlight control signal of closing LCDs, LCDs is not had backlight, the instruction that touch-screen contact control module sends is the power supply of closing touch-screen USB controller, touch-screen is touched invalid, to reach the content exposed preventing on display screen, display backlight is aging and touch-screen false touch moving and misoperation, when needs are observed displaying contents or are passed through touch screen operation computing machine, only need again press the button on panel, backlight control module is controlled the USB controller power source of backlight switch display backlight and touch-screen contact control module control touch-screen and is opened.
The utility model can manual-lock/unlatching industrial computer screen and the backlight module of touch-screen, allows industrial computer normally operation in the situation that not showing; Also can close backlight and touch function screen, the life-span of screen is improved, and can prevents maloperation touch-screen simultaneously.
