Abstract
The invention relates to a man-machine interface device with expanding function, wherein the invention is formed by panel and printed circuit board; said panel has the first key device electrically connected to the printed circuit board with expanding interface, to selectively connect the selective second key device.
Description
Technical field
The present invention relates to a kind of human-computer interface device, relate in particular to a kind of human-computer interface device that can realize the function expansion by extended interface and at least one external key with extended function.
Background technology
Being showing improvement or progress day by day and popularizing along with electronic technology, people usually need to operate some man-machine interfaces (Human Machine Interface) in daily life and reach facility in life or the work, for example can use man-machine interface to control cash machine, sky parking, every plant produced equipment etc.The basic function of man-machine interface possesses exactly input/output interface.Input interface can be made up of several button simply, also can be a keyboard, or the input media of other data of different types, numerical value and state, for example Touch Screen (touch pad) or mouse etc.And output interface can be made of several pilot lamp simply, also can provide seven sections display modules that numerical value shows, but or the LCD of display text information and pattern, be widely used in the operation of various machines by different way.
Widespread usage is divided into two types substantially in the man-machine interface of machine: i.e. touch and non-touch.The advantage of the man-machine interface of touch is that all buttons are defined within whole screen, and the meaning of each button not only can be redefined with different pictures, and the title of keypress function can directly be presented in the button; Its shortcoming is that price is higher, especially do not need multi-functional man-machine interface like this in easy machine or equipment, and the man-machine interface of another kind of non-touch is exactly the product that satisfies these class needs.The man-machine interface of non-touch except by a less LCD as output interface, aspect input interface, also have several function keys or numerical key is imported as numerical value, though function key can be redefined according to different pictures, the title of button itself can't change.Generally must with mode word the function that button is redefined be described at picture, this is very inconvenient for the man-machine interface product of the very little non-touch of screen to the user.
Shown in Figure 1A is known non-touch man-machine interface 10, and it comprises LCD 100, function key group 110 (for example can comprise function keys such as F1, F2) and the direction key group 120 (for example can comprise the upper and lower, left and right key) of reduced size.Though the function of user's redefinable button, the button title can't be revised, and sometimes because button is too little, makes operate unusual inconvenience of site operation personnel.Shown in Figure 1B is another known non-touch man-machine interface 20, and it comprises LCD 200, function key group 21O (for example can comprise function keys such as F1, F2), direction key group 220 (for example can comprise the upper and lower, left and right key) and numerical key group (keypad) 230.Though this known non-touch man-machine interface 20 has bigger size, thereby make the button title to make to substitute the button title (for example: move, stop, advancing or retreat etc.) that redefines the client and want by the inscription plate (not shown) in middle layer, but being the middle layer, its shortcoming is subject to the influence of humidity, potential quality problems are arranged, and the client wants self manufacture inscription plate, and this has also increased client's cost.
Content of the present invention
Fundamental purpose of the present invention is to solve the defective of above-mentioned prior art, avoids the existence of defective.The present invention provides one group of signaling interface in existing man-machine interface, its function key with panel is identical, the function key that allows the user can not use former man-machine interface to provide, draw signaling interface and use this to organize distribution voluntarily from the operation-interface of control box, like this, the function key on the former man-machine interface can be need not be confined to, and the switch or the button of appropriate color or size can be selected, indicate suitable explanatory note simultaneously, thereby make that site operation personnel's operation is simpler and easy.
In order to achieve the above object, the invention provides a kind of human-computer interface device with extended function, this human-computer interface device mainly is made up of panel and printed circuit board (PCB), wherein panel is provided with first key device that is electrically connected on printed circuit board (PCB), printed circuit board (PCB) provides extended interface, optionally to connect user's second key device of design and installation voluntarily.
