Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Term " first " and " second " in the description and claims of this application etc. are for distinguishing different pairs
As, rather than it is used for the particular order of description object.For example, the first system and second system etc. are different to be for distinguishing
System, rather than the particular order for describing system.
In the embodiment of the present application, " illustrative " or " such as " etc. words for indicate make example, illustration or explanation.This
Application embodiment in be described as " illustrative " or " such as " any embodiment or design scheme be not necessarily to be construed as comparing
Other embodiments or design scheme more preferably or more advantage.Specifically, use " illustrative " or " such as " etc. words purport
Related notion is being presented in specific ways.In addition, unless otherwise indicated, " multiples' " contains in the description of the embodiment of the present application
Justice refers to two or more.
When in the prior art, after the key signals for receiving matrix keyboard input, key response equipment may held
Other can not the interrupting of the tasks of row, be thus likely to cause processing equipment can not the input of real-time response matrix keyboard key assignments,
Need to wait after the completion of current task can the input of response matrix keyboard key assignments.It will show as having pressed matrix key at this time
Some key of disk, but key response equipment cannot timely respond to key-press input or key response equipment response key-press input
Delay it is longer.
To solve the above problems, the embodiment of the present invention provides a kind of button processing method, equipment and system.The keystroke handling
Method sends interrupt signal to second system first after detecting with key-press input, then further according to key-press input to the
Two system sends key signals；Due to first having sent interrupt signal to second system after detecting with key-press input,

Delay in journey improves the real time response speed of system.
As shown in Figure 1, key processing system provided in an embodiment of the present invention, comprising: the first system 10 and second system 20.
Wherein, the first system 10 is specifically as follows the system equipment without real-time, second system 20 can for
The system equipment of hard real-time.All kinds of fieldbus, example can be passed through between key detection system 10 and key response system 20
Such as: Ethernet/IP, CAN, RS485 connection, and by bus to the signal between the first system 10 and second system 20 into
Row transmission.
Based on above content, the embodiment of the present invention provides a kind of button processing method, specific referring to shown in Fig. 2, should
Method includes:
S21, the first system are detected whether with key-press input.
Optionally, as shown in figure 3, the first system includes: a plurality of line 31 (R1, R2, R3 ... RN), a plurality of and institute
It states line 31 (R1, R2, R3 ... RN) alignment 32 (C1, C2, C3 ... CM) arranged in a crossed manner and is located at line and alignment friendship
Key 33 on the position of fork.
Wherein, when any key has key-press input, the line and alignment intersected at the key is connected.Such as: when
When key K3-2 has key-press input, line R3 is connected with alignment C2.
It detects whether to can specifically include with key-press input in above-mentioned steps S21:
S211, to a plurality of line (R1, R2, R3 ... RN) the input low level voltage, to a plurality of alignment (C1,
C2, C3 ... CM) first end input high level, detect the voltage value of the second end of a plurality of alignment.
In above-mentioned steps S211, if the voltage value of the second end of a plurality of alignment (C1, C2, C3 ... CM) is height
Level executes step S222；If the voltage value of the second end of one or more alignment is low level, S223 is thened follow the steps.
S222, no key-press input is determined.
S223, determine that there is key-press input.
Further, detect whether to have the working principle of key-press input to carry out the first system in above-described embodiment below
Illustrate:
First to a plurality of line (R1, R2, R3 ... RN) equal input low level, to a plurality of alignment (C1, C2,
C3 ... CM) first end input high level, without press key pressing when, line is not turned on alignment, the voltage on each alignment
It is high level；If key is pressed, corresponding line can be connected with alignment for key, and then drag down the voltage on alignment,
The voltage on alignment is low level at this time, therefore can be determined whether by the voltage on detection alignment by key pressing.
In above-mentioned steps S21, if detecting with key-press input, following step S22 is executed；If detecting does not have
Key-press input, then return step S21, detects whether again with key-press input.
S22, the first system send interrupt signal to second system.

(t1, t2, t3 ... tn), in first time period t1, to line R1 input low level, other line floatings or the high electricity of input
Flat, in second time period t2, to line R2 input low level, other line floatings or input high level ... ... are in the n-th time
When section tn, to line RN input low level, other line floatings or input high level.
B, the first alignment and the first line are determined.
Wherein, it is low level alignment that first alignment, which is the voltage value of second end, and first line is first row
When the voltage value of the second end of line is low level, the line of input low level.
C, the key at first alignment and the first line crossover location is determined as to the position of the key-press input.
Specifically, referring to shown in Fig. 4, it is alignment Cx that the voltage value of second end, which is low level alignment, and the of alignment Cx
It is ty that the voltage value at two ends, which is the low level period, then the line Ry of input low level when the first line is y time period t y,
Alignment Cx and line Ry crossover location (position key Ky-x) are then determined as the position of the key-press input.
The key assignments of S242, the first system key-press input according to the position acquisition of the key-press input.
Specifically, the first system can be by way of calculating or tabling look-up come according to the position acquisition institute of the key-press input
State the key assignments of key-press input.
S243, key signals are generated according to the key assignments of the key-press input.
The corresponding movement of key signals described in the key response task execution of S25, second system by scheduling.
Button processing method provided by the above embodiment is sent out to second system first after detecting with key-press input
Interrupt signal is sent, then sends key signals to second system further according to key-press input；Due to detecting with key-press input
Interrupt signal first is had sent to second system afterwards, therefore second system can in advance be scheduled key response task, in turn
After receiving second system and sending key signals, the key signals are handled by the key response task of scheduling,
