Abstract

PURPOSE:To prevent the misoperation of a switch, and at the same time to facilitate the operability thereof by giving a warning sound when the depression of the switch is still continued even after the passage of a limited time, and by refusing to take in a switch signal when the switch is depressed and subsequently released late from its depression within a delay time. CONSTITUTION:A switch signal S1 is continuously outputted after the passage of a delay time t1 and yet even after the further passage of a limited time T when a misoperation in having turned on the switch is not found or when there is not found the continuous on phase of the switch resulting from contacting another thing thereto. A switch control unit 2 in this case outputs a pulse-duration (T) confirmation signal S2 and its subsequent short pulse-doration signal S3 respectively, and then a buzzer control unit 3 entering both of the signals, S2 and S3 into itself outputs a buzzer drive signal S5 to a buzzer unit 4 which consequently notifies the presence of these signals by giving a buzzing sound. At the same time, the switch control unit 2 detecting an excess of the output duration of the confirmation signal S2 over the limited time T judges the switch to be misoperated for refusing to output an operation control signal S4. The switch signal S1 is thus prevented from being taken in an equipment unit 5 to prevent the occurrence of any misoperation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an erroneous operation prevention switch device and a suinochi introduction method, and particularly to an erroneous operation prevention switch device and a switch introduction method used in medical equipment such as electrocardiographs.

[Conventional technology]

(1) Background of the Invention It is generally well known that medical devices such as electrocardiographs are provided with various switches such as a power switch, a sensitivity switch, and an instrument switch.

Normally, when such a switch is operated, a switch input is made immediately after the switch mechanism is operated, so if the switch is operated incorrectly due to carelessness, subsequent operations and measurements are often hindered.

Furthermore, in recent years, soft-touch switches have been increasingly used as such switches, and a switch input can be performed by simply touching the soft-touch switches.

Therefore, although it is easier to operate than a normal switch, it is extremely common for erroneous operations to occur.

Under such conditions, there is a desire for a switch that satisfies both properties: easy to operate, but at the same time extremely unlikely to be erroneously operated.

(2) Conventional Example Conventionally, there have been two types of switch devices for preventing erroneous operation: a push type and a lock type.

The push type is a method in which the switch input is not performed immediately after the switch is turned on, but only after the switch is pressed for several seconds. On the other hand, the lock type is a type in which the lock is initially released and then the lock is locked after the switch is operated.

[Problem to be solved by the invention]

In the case of the above press type, if you accidentally press the button for a moment, you can avoid the switch input by stopping the press.
Misoperation can be prevented.

However, there are cases where the user does not realize that he or she is inadvertently pressing the switch and presses the switch for a long time.In this case, the switch input cannot be avoided and erroneous operation cannot be prevented.

Such erroneous operations are particularly likely to occur when other nerves are concentrated, such as during surgery.

In addition, in the case of soft-touch switches, it is only necessary to press lightly, so not only a finger press but also a touch with a part of the body or an instrument can cause an input if the touch lasts for a long time.

On the other hand, with the lock type, it is easy to forget to turn on the switch after unlocking and lock it again, and in this case, the user forgets how to operate the device, resulting in uncertain and unstable measurements.

In addition, multiple operations such as unlocking, switching on, and locking are required, and the operation cannot necessarily be said to be easy.

In short, conventional methods have had the problem of not being able to prevent erroneous operation of the switch, causing measurement uncertainty and instability, and not being easy to operate.

An object of the present invention is to eliminate erroneous switch operations and to facilitate switch operations while ensuring measurement reliability and safety.

[Means to solve the problem]

The above problem involves inputting the switch signal Sl and delay time L1.
If the switch signal 31 continues to be input even after the elapse of time,
In addition to outputting the confirmation signal S2, if the switch signal S1 is no longer input within the limited time T, the operation control signal S4 is output after the confirmation signal S2, or the switch remains active even after the limited time T has elapsed. When the signal S1 continues to be input, a warning signal S3 is output after the confirmation signal S2, and the above switch signal S1 is input, and when the switch signal Sl is no longer output within the delay time tl, the above A switch control unit 2 that does not output the confirmation signal S2, the warning signal S3, and the operation control signal S4, and a buzzer that receives the confirmation signal S2 or the confirmation signal S2 and the warning signal S3 and outputs a buzzer drive signal S5 corresponding to each signal. An erroneous operation prevention switch device characterized by comprising a control section 3 and a buzzer section 4 which inputs the buzzer drive signal S5 and outputs a buzzer sound BZ, and when the switch is pressed and continues to be pressed even after the delay time elapses. In addition to emitting a confirmation sound, if the switch is released within a limited time, the switch signal is captured, or if the switch is still pressed after the limited time has elapsed, a warning sound is emitted and the switch is pressed. This is solved by a switch capture method characterized in that the switch signal is not captured if the switch is released within the delay time.

[For production]

As described above, according to the present invention, when the switch signal SL is input and the switch signal St continues to be input even after the delay time L1 has elapsed, the confirmation signal S2 is output, and within the limited time T, When the switch signal St is no longer input, the operation control signal S4 is output after the confirmation signal S2, or the switch signal S
When t continues to be input, a warning signal S3 is output after the confirmation signal S2, and the switch signal 31 is input, and when the switch signal Sl is no longer output within the delay time 11, the above lI ! A switch control unit 2 that does not output the confirmation signal S2, the warning signal S3, and the operation control signal S4, and a buzzer that receives the confirmation signal S2 or the confirmation signal S2 and the warning signal S3 and outputs a buzzer drive signal S5 corresponding to each signal. An erroneous operation prevention switch device characterized by comprising a control section 3 and a buzzer section 4 which inputs the buzzer drive signal S5 and outputs a buzzer sound BZ, and when the switch is pressed and continues to be pressed even after the delay time elapses. In addition to emitting a confirmation sound, if the switch is released within a limited time, the switch signal is captured, or if the switch is still pressed after the limited time has elapsed, a warning sound is emitted and the switch is pressed. Each of the switch acquisition methods is provided, which is characterized in that the switch signal is not acquired when the switch is released within the delay time.

Therefore, a buzzer sounds a few seconds after pressing the switch, and if the switch operation is correct, the switch can be input by releasing the switch a few seconds later.

On the other hand, even if this buzzer sounds, if the user does not notice the error in the switch operation and presses the switch for a long time, an additional warning sound will sound and the switch will not be input.

This prevents erroneous operation of the switches and switches, and also facilitates switch operation while ensuring measurement reliability and safety.

In other words, by requiring two actions: pressing and releasing the switch, it is now possible to confirm whether the switch operation is correct or not, and to prevent erroneous operations such as accidentally touching the switch or continuing to press the switch.

〔Example〕

Hereinafter, the present invention will be explained by way of examples and with reference to the accompanying drawings.

(1) First invention FIG. 1 is a diagram showing an embodiment of the first invention.

In the figure, reference numeral 1 is a switch section, 2 is a switch control section, 3 is a buzzer control section, 4 is a buzzer section, and 5 is a device section.

The switch unit 1 may be any switch such as an instrument switch or a sensitivity switch, and is a device that inputs the original signal SO and outputs the switch signal St.

The switch control unit 2 is a device that outputs a confirmation signal S2 and an operation control signal S4, or a warning signal S3 following the confirmation signal S2, depending on how the switch signal S1 is input.

The buzzer control unit 3 receives the confirmation signal S3 or the confirmation signal S3.
This is a device that inputs warning signals S4 and outputs corresponding buzzer drive signals S5.

The buzzer unit 4 inputs the buzzer drive signal S5,
This is a device that outputs a buzzer sound BZ.

The device 5 may be any device as long as it is operated by the switch unit 1, in addition to medical devices such as electrocardiographs.

Hereinafter, the operation of the first invention having the above-mentioned ti 戊 will be explained based on FIG. 2.

■If you immediately notice an incorrect operation.

If, after turning on the switch, you immediately notice the erroneous operation and turn it off, the switch signal S1 will not be input to the switch control unit 2 before the delay time Ll elapses (Fig. 2 (A) (1)
).

For this reason, the switch control section 2 does not output the confirmation signal S2 that should rise after tl has elapsed, nor does it output the warning signal S3 that follows, and accordingly, the buzzer section 4 does not generate any sound.

Furthermore, since the switch control section 2 does not output the operation control signal S4 ((3) in FIG. 2A), the switch signal S1 is not taken into the device section 5, and the A-device 5 does not malfunction.

■If the operation is correct.

When the switch is turned on, the switch signal Sl is input to the switch control section 2 (Fig. 2 (B) (1)), and when the delay time tl has elapsed, the switch control section 2 transmits the confirmation signal S2 to the buzzer control section. 3, the operation control signal S4 is output to the equipment section 5 (Fig. 2 (B) (2) (3)).
).

The buzzer control unit 3 that has received the confirmation signal S2 outputs a corresponding buzzer drive signal S5 to the buzzer unit 4.

The buzzer unit 4, which receives the buzzer drive signal S5, electromagnetically vibrates its iron piece to produce a buzzer sound BZ (FIG. 1).

If you confirm that the switch operation is correct after the buzzer sound BZ sounds and turn off the switch within the limited time T, the switch signal St will no longer be output at this point (Fig. 2 (B))
(1)). The switch control unit 2 detecting this stops outputting the confirmation signal S2 ((2) in FIG. 2(B)).

Therefore, the buzzer control unit 3 stops outputting the buzzer drive signal S5 ((4) in FIG. 2).

On the other hand, the switch control unit 2 detecting that the confirmation signal S2 is no longer output outputs the operation control signal S4 at the falling edge of the confirmation signal S3 (see FIG. 2(B)).
3)).

The equipment section 5 that has received the operation control signal S4 takes in the switch signal S1 and starts operating.

■If you turn on the switch but do not realize that you have made a mistake, or if something else touches the switch and the switch continues to turn on, you do not notice it.

In this case, the switch signal S1 continues to be output even after the delay time tl has elapsed and the limit time T has elapsed (see Fig. 2 (C
) (1)). In this case, the switch control unit 2 outputs a confirmation signal S2 with a pulse width T and a subsequent warning signal S3 with a short pulse width ((2) in FIG. Since the $11 control unit 3 outputs the buzzer drive signal S5 ((4) in FIG. 2(C)), the buzzer unit 4 sounds these signals with the buzzer sound BZ.

At the same time, the switch control unit 2 detects that the confirmation signal S2 exceeds the limit time T, determines that the operation is erroneous, and does not output the operation control signal S4 ((3) in FIG. 2(C)).

As a result, the switch signal S1 is not taken into the section 5, and no malfunction occurs.

Therefore, malfunction of the switch is prevented.

(2) Second invention FIG. 3 is a diagram showing an embodiment of the second invention.

After the switch is turned on in the stem Pi, it is determined in the stem P2 whether a delay time (l) has elapsed.

If the delay time L1 has elapsed, it is determined in step P3 whether the switch signal Sl is still being input.

The switch is released before the delay time ti elapses, and the switch signal S
If l is not input, the error in the switch operation is immediately noticed, so there is no need for a confirmation sound, but in order to ensure that the person operating the switch understands this, it is necessary to It is preferable to generate a switch rejection sound.

If it is determined in step P3 that the switch signal S1 is still being input even after the delay time L1 has elapsed, the process proceeds to the next step P4 and a confirmation sound is generated.

In step P5, it is determined whether or not the limited time T has elapsed, and in step P6, this limited time T
During this period, it is determined whether the switch signal Sl can be input.

If the operator hears the confirmation sound, thinks that the switch operation is correct, and releases the switch within the limited time T, the next step P7
In step P8, it is preferable to capture the switch signal St and generate a switch capture sound in order to ensure that the switch signal St is captured.

In the final step P9, the operation control signal S4 is output to operate the device section 5.

However, if you continue to press the switch even after the limited time T has elapsed in SteSop P6, in SteSop P10,
A warning sound is generated, preferably in step Pll, a switch rejection sound is generated to inform the operator of this, and the switch signal S1 is not captured.

[Effects of the Invention] As described above, according to the present invention, when the switch signal S1 is input and the switch signal S1 continues to be input even after the delay time L1 has elapsed, the confirmation signal S2 is output and the limitation is When the switch signal St is no longer input within the time T, the operation control signal S4 is output after the confirmation signal S2, or the switch signal S is output even after the limited time T has elapsed.
When l continues to be input, a warning signal S3 is output after the confirmation signal S2, and the switch signal Sl is input, and if the switch signal S1 is no longer output within delay time t1, the confirmation signal S3 is output after the confirmation signal S2. A switch control unit 2 that does not output the signal S2, the warning signal S3, and the operation control signal S4, and a buzzer control that inputs the confirmation signal S2 or the confirmation signal S2 and the warning signal S3 and outputs a buzzer drive signal S5 corresponding to each signal. section 3 and the buzzer drive signal S5,
and a buzzer part 4 that outputs a buzzer sound BZ.If the switch is pressed and continues to be pressed even after the delay time elapses, a confirmation sound is emitted and the switch is switched off within a limited time. When you release the switch signal, or when you continue to press Suinochi even after the limited time has elapsed. A technical measure has been taken in which a switch signal is not captured if a warning sound is emitted and the switch is pressed and released within a delay time.

Therefore, a buzzer sounds a few seconds after pressing the switch, and if the switch operation is correct, the switch can be input by releasing the switch a few seconds later.

On the other hand, even if this buzzer sounds, if the switch is pressed for a long time without noticing an error in the switch operation, an additional warning sound will sound and the switch will not be input.

Therefore, the technical effects of preventing erroneous operation of the switch and facilitating switch operation while ensuring reliability and safety of measurement are achieved.

In other words, by requiring two actions: pressing and releasing the switch, it is possible to confirm whether the switch operation is correct or not, and to prevent erroneous operations such as accidentally touching the switch or holding down the switch.

Furthermore, it is an interactive switch/7-touch device that uses a buzzer sound to confirm the two operations of turning on and off the switch, making it extremely easy to operate and without causing any erroneous operation.
If applied to the recent software 1/evening switch, the advantages will be even more prominent, and since the buzzer sound is used, there are various additional effects such as the ability to operate the switch while operating other equipment.
