Abstract

The invention discloses a keyboard redundant method and structure based on multiple keys in the same region. The method comprises the following steps: forming a single multiple-key unit by a plurality of sets of conducting contacts; forming a keyboard input region by the plurality of single multiple-key units; and when any one group of keyboard working at present in the keyboard input region or a system connected with the set of the keyboard has faults, starting the other set of keyboard or system by a control main board and keeping a normal working state of the keyboard input region, wherein the structure based on the method is shown as the description. With the adoption of the keyboard redundant method and structure, the loss caused by the fact that a keyboard input function is lost when a man-machine interface has faults is effectively solved, and man-machine interaction can be continuously guaranteed; and the social benefits and the safety and reliability of industrial control are greatly improved.

Description

Keyboard redundancy approach based on the multiple button of same area and structure

Technical field

The present invention relates to traffic and industrial control field, especially relate to a kind of keyboard based on the multiple button of same area Redundancy approach and structure.

Background technology

Keyboard, as a kind of input equipment of man-machine interaction, has important at the vehicles and industrial control field Effect, these fields are the highest to the reliability requirement that man machine interface is mutual, as broken down, may lead Cause serious consequence.

The keyboard used at the vehicles and industrial control field at present all uses single structure, and what equipment ran can It is difficult to ensure that by property.If man machine interface keyboard breaks down, man-machine interaction can be caused to interrupt, make work not Can the most then cause any property loss continuously, heavy then cause casualties, hazardness is very big.If employing double bond Dish redundant fashion, often the vehicles and industrial control field at limited space are difficult to, and use The work habit of person is affected, and brings operational hazards at work.

Summary of the invention

It is an object of the invention to provide a kind of keyboard redundancy approach based on the multiple button of same area and structure, It can avoid the problem that interrupting alternately occurs when breaking down in man machine interface keyboard.

For solving above-mentioned technical problem, embodiments of the present invention provide a kind of based on the multiple button of same area Keyboard redundancy approach, the method is:

Many group conducting contacts are utilized to constitute single multiple push-button unit；

Several multiple push-button units are utilized to constitute key entry area；

In key entry area any one group of keyboard of work at present or the system that is connected with this group keyboard occur therefore Barrier, controls mainboard and then enables another group keyboard or system and keep the normal operating conditions of key entry area.

Wherein, the conducting contact sets number N of single multiple push-button unit is more than or equal to 2.

Wherein, the keyboard structure of the method is touch keyboard, mechanical keyboard or inductive keyboard.

Wherein, multiple push-button unit has identical work input area.

Utilizing the structure that keyboard redundancy approach based on the multiple button of same area processes, this structure includes: Carry out in interactive process instruction input keyboard area (1), this keyboard area include several with Control the multiple push-button unit (3) that mainboard (2) is connected, there is inside each multiple push-button unit the conducting of N group Contact, N >=2；

N set and control the keyboard circuit that is connected of mainboard, often overlaps keyboard circuit all each multiple with keyboard area One group of conducting contact of push-button unit is connected.

Wherein, the keyboard structure in this structure is touch keyboard, mechanical keyboard or inductive keyboard.

Wherein, each group conducting contact of multiple push-button unit has identical triggering working area.

There is advantages that when efficiently solving man machine interface fault that keyboard entry function is lost to make Become loss, can persistently ensure man-machine interaction, substantially increase social benefit and the safety of Industry Control and Reliability.

Detailed description of the invention

For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, Below in conjunction with specific embodiment, the present invention is expanded on further.

A kind of keyboard redundancy approach based on the multiple button of same area, the method is:

Utilizing how group conducting contacts constitute single multiple push-button unit, the group number N of conducting contact is more than or equal to 2, And multiple push-button unit has identical work input area；

Several multiple push-button units are utilized to constitute key entry area；

The scope of application of said method includes but are not limited to following keyboard structure: touch keyboard, mechanical keyboard, Inductive keyboard.

Specifically, utilize the structure that keyboard redundancy approach based on the multiple button of same area processes, ginseng As shown in Fig. 1-3, this structure includes: carry out the keyboard area 1 of instruction input in interactive process, This keyboard area includes several and controls the multiple push-button unit 3 that mainboard 2 is connected, in each multiple push-button unit Portion has many group conducting contacts.

Seeing Fig. 3, the group number of described conducting contact is more than or equal to 2, and N group shown in this figure cooperates Conducting contact, and, each group conducting contact of multiple push-button unit has identical triggering working area.

Having one group of keyboard to play a role when man machine interface is normal, this group keyboard or the system being connected with this keyboard occur Second group of keyboard or system can be switched to during fault at once, and so on, make the input function of man machine interface hold Continuous work, does not affect man-machine interaction.These buttons are to work alone, and will not produce any impact each other.

See Fig. 4, the figure shows the knot that keyboard redundancy approach based on the multiple button of same area processes The schematic diagram of structure, it includes multiple push-button unit I4, multiple push-button unit II5 ... multiple push-button unit N, Here N >=3, multiple push-button unit I, multiple push-button unit II ... multiple push-button unit N is internal to be arranged There are many group conducting contacts, and in figure as a example by two groups of conducting contacts, two groups of conductings of each multiple push-button unit are touched Point is connected to keyboard circuit I7, keyboard circuit II8 respectively, if conducting contact is N group, then corresponding is to set Being equipped with N number of keyboard circuit, keyboard circuit here is right with the group number of the conducting contact within multiple push-button unit Should.When breaking down in the arbitrary one group of multiple push-button unit conducting contact being connected with keyboard circuit II, then control Mainboard enables keyboard circuit I and turns on contact with keyboard circuit I another group even, thus keeps keyboard work The seriality made.

Multiple push-button unit surface can arrange the hemispherical projections of some point-like, and sets on the surface of hemispherical projections Put luminescent coating, in the case of train entrance tunnel, evening or illuminator are the best, can improve whole The resolution of individual redundancy structure position, can increase again sense of touch, it is achieved sense of touch and vision dual fail-safe.

It will be understood by those skilled in the art that the respective embodiments described above are to realize being embodied as of the present invention Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from this Bright spirit and scope.
