Abstract

PURPOSE:To rapidly input data from the 1st input device by inputting data from the 2nd input device based upon operator's operation only at the time of judging that continuous data inputted from the 1st input device are not changed. CONSTITUTION:A computer 3 fetchs data alpha from an input device 1 and compares the current input data with the preceding fetched data alpha. At the time of judging the coincidence of both the data, the computer 3 judges the presence or absence of an input from an input device 2 and inputs data alpha from the device 2 to process the data alpha. When the preceding input data alpha are different from the current data alpha inputted from the input device 1, the data alpha are converted into internal data and processed. Since data are inputted from the input device 2 only at the time of judging that the data from the input device 1 are continuous and are not changed, the input from the input device 1 can rapidly be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input method for a computer that is connected to an input device that inputs data continuously and an input device that inputs data only when operated by an operator.

[Conventional technology]

As shown in FIG. 2, consider a data input method in a computer 3 in which an input device 1 that inputs data continuously and an input device 2 that inputs data only when operated by an operator are connected.

A conventional technique of this type will be explained with reference to a flowchart shown in FIG.

The computer 3 periodically takes in data α sent from the input device 1 (step SL).

Next, this data α is converted into internal data of the computer 3 (step 83) and processed within the computer 3 (step S4). Next, it is determined whether there is an input from the input device 2 by the operator (step 85), and if there is no input, the process returns to step S1 and waits until the next data α is sent.

On the other hand, if there is input from the operator, input device 2
Step S6)
, the process is performed inside the computer 3 (step S7), and the process returns to step S1.

By repeating steps 1 to 7 above, the data α continuously sent from the input device 1 is processed, and if there is data β sent from the input device 2 by operator operation, that data is also processed.

[Problem to be solved by the invention]

That's right.

Let tl to t7 be the time required for each step from step S1 to step S7. If there is no input from the input device 2, step 86. Since step S7 is not executed, T+=t,+ts+t4+ts
. . . The data α from the input device 1 can be taken in in the time (1). Also, when there is input from the input device 20, T2=t++ts+tt+ts+ts+ty...
- (2) It takes time, but if the next data α input from the input device 1 during this time is buffered and fetched later, there will be no problem.

As described above, one piece of data can be received from the input device 1 every T1 seconds. However, since the data conversion in step S3 takes time, the value of T1 becomes large. For this reason, there was a drawback that data could not be taken in from the input device l quickly enough.

[Means to solve the problem]

The data input method of the present invention is a data input method for a computer connected to a first input device that inputs data continuously and a second input device that inputs data only when operated by an operator. a first step of determining whether there is a change in the data input from the input device;
The method includes a second step of inputting data from the second input device only when it is determined that the data from the first input device does not change in the first step.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a flowchart showing one embodiment of the present invention. This embodiment is applied to the system shown in FIG.

First, the computer 3 waits for data α from the input device 1 (step Sl). Next, the data α is compared with the previously captured data (step 82), and if they are the same, the process proceeds to input processing from the input device 2 starting from step S5, but if they are different, the data α is converted to internal data (step S3).
), data α input from input device 1 without processing
Just compare them as is. If it is determined in step S2 that the data α are the same, it is determined whether there is an input from the input device 2 (step 85), data β is input from the input device 2 (step S6), and the data is processed (step 87). ).

The time TN used to input data α from the input device 1 as described above is as follows.

Let tl to t7 be the time required for each step from step S1 to step S7. When the data α from the input device 1 changes, the time used to input the data α from the input device 1 is Ts=t ++t t+t s +t s
...... (3). When the data α from the input device 1 does not change, the time used to input the data α from the input device 1 is determined by the conversion to internal data in step S3 based on the converted data in step S3 when inputting the previous data α. can be used as is, so T4= t ++ t 2+ t s...
...(4). Furthermore, when there is an input from the input device 2 due to operator operation, Ts"" t 1+ t 2+ t a+ t s+
It becomes tr.

Here, 13,1. >1. Therefore, T 3 > T
It becomes 4. Also, since there are fewer inputs than input device 2, steps 86. The data α inputted from the input device 1 during the processing in step S7 can be buffered and processed later. From the above, T's = T
It becomes 3.

Comparing the time required to import data α from the input device 1 with the conventional method shown in FIG. 3, the conventional method has T
+= t ++ t s+ t 4+t s, and in this example, TN=t++ tz+ts+t<. No special data conversion is required in step S2, and the effect of step S5 is that the data input from the input device 2 is checked.
