Accompanying drawing explanation
With reference to appended accompanying drawing, to describe embodiment of the present utility model more fully.But, appended accompanying drawing only for illustration of and elaboration, do not form the restriction to the utility model scope.
Fig. 1 is the utility model structural representation.
Embodiment
In order to make the technical solution of the utility model and advantage easy to understand more, be described in further detail below in conjunction with accompanying drawing.Should illustrate, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
The utility model main thought: the adjustable scheme of contrast of segment encode LCD liquid crystal is applied on industrial servo sewing machine electric control operation panel, make user can according to the installation site of guidance panel, oneself visual angle and operating habit, the different contrast of setting operation panel segment encode LCD liquid crystal is carried out by the button of guidance panel, make displaying contents high-visible, reduction kopiopia, enhances productivity.
As shown in Figure 1, in the utility model, relate to a kind of control system, this control system, in industrial sewing machine, wherein, comprising: input equipment, host controller device and light-emission display part.
Input equipment, in the utility model, preferably keyboard input devices, user is by this keyboard input devices input of control commands;
Host controller device, this host controller device is connected with keyboard input devices, carries out programmable light-emission display part brightness or contrast adjustment control with the order inputted according to keyboard input devices.
Memory module and control module is provided with in this host controller device, memory module is used for storing the order that inputted by keyboard input devices of user, control module is connected with memory module, and this control module transfers order to control the different luminous lighting of brightness of light-emission display part or the adjustment of different contrast from memory module.
Light-emission display part, is connected with host controller device, under controlling at host controller device, realize the different luminous lighting of brightness of light-emission display part or the adjustment of different contrast.This light-emission display part includes:
Back light apparatus, this back light apparatus is connected with host controller device, to realize the luminous lighting of the different brightness of back light apparatus under the control of master control equipment;
Liquid crystal apparatus, is connected on host controller device equally, gets off to show different segment encode equally in the adjustment of host controller device.
In the utility model, liquid crystal apparatus adopts LCD liquid crystal apparatus, because Traditional CRT Display leans on the electromagnetic field of deflection coil generation to control electron beam, and due to electron beam impossible absolute fix on screen, so often there is set distortion in various degree in CRT monitor, linear distortion situation, and LCD there will not be any geometric distortion, linear distortion due to its principle.And the power consumption of LCD and volume all have a clear superiority in.
In the utility model, in host controller device, be also provided with driver module, with the driving voltage of control LCD liquid crystal apparatus, produce reasonable contrast.This driver module is connected with LCD liquid crystal apparatus, so just can produce according to driver module driving circuit the adjustment that driving voltage realizes LCD liquid crystal apparatus different contrast.
In the utility model, memory module and control module is also provided with in master controller, memory module is connected with keyboard input devices, keyboard input devices input command, memory module stores the order of this keyboard input devices input, control module is connected with memory module, transfers storage order in a storage module to control the different luminous lighting of brightness of light-emission display part or the adjustment of different contrast.
In the utility model, back light apparatus adopts LED group, and its relies on the electronics in heterojunction semiconductor to move more direct luminescence by the energy that potential barrier produces, and the light fixture made by LED does not produce heat due to luminescence process, energy conversion efficiency is absolutely close, overlong service life.
Be specifically described in conjunction with example
Be made up of keyboard input devices, host controller device, back light apparatus and liquid crystal apparatus, keyboard input devices is directly connected with host controller device, liquid crystal apparatus is connected separately with host controller device respectively with back light apparatus, and back light apparatus is arranged on the back side of liquid crystal apparatus.
User buys and after installing guidance panel, start, guidance panel runs, and LCD liquid crystal normally shows, and now the contrast of LCD is at default setting, might not be optimum contrast.Be accustomed to according to oneself operating habit and visual angle, operation keyboard enters corresponding LCD lcd contrast regulating parameter, continue heighten by related keyboard or turn down LCD lcd contrast, user's input information is sent to host controller device inside by keyboard input devices simultaneously.The processor of host controller device is according to the contrast adjustment class preset or also can step-less adjustment contrast, the driving voltage arranging LCD liquid crystal driver module integrated in host controller device further arranges pin voltage, indirectly controls the LCD liquid crystal drive voltage of the output of LCD liquid crystal driver module.Normally used LCD liquid crystal contrast under low driving voltage is lower, and under high driving voltage, contrast then improves.Regulated by input through keyboard, until LCD display effect is best.Continue keypad input equipment, preserve contrast level parameter in host controller device inside.The parameter of preserving last time is directly read in start next time, does not need to reset contrast.
In the utility model, user can according to the installation site of guidance panel, oneself visual angle and operating habit, the different contrast of setting operation panel segment encode LCD liquid crystal is carried out by the button of guidance panel, make displaying contents high-visible, reduction kopiopia, enhances productivity.Simultaneously due to the adjustable LCD liquid crystal of guidance panel, thus the coherence request of the LCD liquid crystal self-contrast degree of manufacturer production is reduced, improve the yields of LCD liquid crystal, reduce further cost.
