Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erroneous operation prevention switch device and a switch taking-in method, and particularly to an erroneous operation prevention switch device and a switch taking-in method used for medical equipment such as an electrocardiograph.

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

Normally, such a switch is input as soon as the switch mechanism is operated. Therefore, if the switch is inadvertently and erroneously operated, the subsequent operation and measurement often suffer.

Further, recently, a soft touch switch has been often applied to such a switch.

With this soft touch switch, switch input is performed with a simple touch.

Therefore, it is easier to operate than a normal switch,
Very often, erroneous operations occur.

In such a state, the operation is easy, but on the other hand, there is a demand for a switch that satisfies both the properties of extremely erroneous operation.

(2) Conventional Example Conventionally, as a switch operation for preventing an erroneous operation, there are a push type and a lock type.

The pressing type is a method in which a switch is not input immediately after the switch is turned on, but is input only when the switch is pressed for several seconds.

On the other hand, one lock system is a system in which the lock is released first and the lock is locked after the switch is operated.

[Problem to be Solved by the Invention] In the case of the above-mentioned pressing type, if the user inadvertently accidentally presses the button for a moment, by stopping the pressing, the switch input can be avoided and the erroneous operation can be prevented.

However, the user sometimes inadvertently presses the switch and presses it for a long time.

Therefore, in this case, switch input cannot be avoided, and erroneous operation cannot be prevented.

In particular, when nerves are concentrated elsewhere, such as during surgery, such erroneous operations are likely to occur.

Further, in the case of a soft touch switch or the like, since it is only necessary to press lightly, not only when a finger is pressed but also when a part of the body or an appliance is touched, an input is made when the touch is for a long time.

On the other hand, in the lock type, it is easy to forget to turn on the switch after unlocking and lock again. In this case, the operation method is forgotten, and the measurement becomes uncertain and unstable.

Further, a plurality of operations such as unlocking, switch-on, and locking are required, and the operation is not always easy.

In short, conventionally, erroneous operation of the switch could not be prevented,
There is a problem that the operation is not easy while the measurement is uncertain and unstable.

The object of the present invention is to eliminate erroneous operation of the switch,
An object of the present invention is to make it easy to operate switches while ensuring the reliability and safety of measurement.

[Means for Solving the Problems] The above-described problem is caused by inputting the switch signal S1 and outputting the confirmation signal S2 when the switch signal S1 continues to be input even after the delay time t1 has elapsed. When the switch signal S1 is no longer input, the operation control signal S4 is output after the confirmation signal S2, or when the switch signal S1 is continuously input after the lapse of the limited time T, The warning signal S3 is output after the confirmation signal S2, the switch signal S1 is input, and when the switch signal S1 is not generated within the delay time t1, the confirmation signal S2, the warning signal S3, and the operation control signal S4 A buzzer control unit 3 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, and the buzzer drive signal Enter S5 and buzzer sound
A buzzer unit 4 for outputting BZ is provided. When the switch is pressed and the switch is kept pressed after the delay time elapses, a confirmation sound is emitted and the switch is operated within a limited time. When the switch is released, the switch signal is captured, or when the switch is kept pressed after the lapse of the limited time, a warning sound is emitted, and when the switch is pressed and released within the delay time, the switch signal is not captured. The problem is solved by a switch taking-in method characterized in that:

[Operation] As described above, according to the present invention, when the switch signal S1 is input and the switch signal S1 is continuously input even after the delay time t1 has elapsed, the confirmation signal S2 is output and the limited time T When the switch signal S1 is no longer input, the operation control signal S4 is output after the confirmation signal S2, or when the switch signal S1 is continuously input even after the lapse of the limited time T, A warning signal S3 is output after the confirmation signal S2, the switch signal S1 is input, and if the switch signal S1 is not generated within the delay time t1, the confirmation signal S2, the warning signal S3, and the operation control signal The switch control unit 2 that does not output S4 and the confirmation signal S2 or the confirmation signal S2 and the warning signal S3 are input, and a buzzer-drive signal S5 corresponding to each signal is input.
Buzzer control unit 3 for outputting the buzzer drive signal
A buzzer section 4 for inputting S5 and outputting a buzzer sound BZ. A audible confirmation sound is generated when the switch for preventing erroneous operation and the switch are pressed and kept pressed after the delay time has elapsed. In addition, when the switch is released within the limited time, the switch signal is captured, or when the switch is kept pressed after the limited time has elapsed, a warning sound is emitted, and the switch is pressed and released within the delay time Each provide a switch capturing method characterized by not capturing a switch signal.

Therefore, a buzzer sounds a few seconds after the switch is pressed. If the switch operation is correct, the switch is input by releasing the switch a few seconds later.

On the other hand, even if the buzzer sounds, if the switch is pressed for a long time without noticing the error of the switch operation, a warning sound is further sounded and no switch input is performed.

For this reason, erroneous operation of the switch is prevented, and the switch operation is facilitated while ensuring the reliability and safety of the measurement.

That is, by requesting the two operations of pressing and releasing the switch, it is possible to confirm the correctness of the switch operation and prevent an erroneous operation such as accidentally touching the switch or keeping the switch pressed.

[Example] Hereinafter, the present invention will be described by way of examples 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 an original signal S0 and outputs a switch signal S1.

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 is a device that receives the confirmation signal S3 or the confirmation signal S3 and the warning signal S4 and outputs a corresponding buzzer drive signal S5.

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

The device 5 is not limited to medical devices such as an electrocardiograph, and may be any device that is operated by the switch unit 1.

Hereinafter, the operation of the first invention having the above configuration will be described with reference to FIG.

Immediately notice a mistake.

If the operator turns off the switch immediately after noticing the erroneous operation, the switch signal S1 is not input to the switch control unit 2 before the delay time t1 elapses (FIG. 2A).
(1)).

For this reason, the switch control unit 2 does not output the confirmation signal S2 to be raised after the elapse of t1, nor the subsequent warning signal S3, and accordingly the buzzer unit 4 does not generate any sound.

Further, since the switch control unit 2 does not output the operation control signal S4 (FIGS. 2A and 3C), the switch signal S1 is not taken into the device unit 5, and the device 5 does not malfunction.

If the operation is correct.

When the switch is turned on, the switch signal S1 is input to the switch control unit 2 (FIG. 2 (B) (1)), and the delay time
When t1 has elapsed, the switch control unit 2 outputs the confirmation signal S2 to the buzzer control unit 3 and the operation control signal S4 to the device unit 5 (FIGS. 2 (B), (2) and (3)). ).

Upon receiving the confirmation signal S2, the buzzer control section 3 outputs a corresponding buzzer drive signal S5 to the buzzer section 4.

The buzzer unit 4 which has received the buzzer drive signal S5 causes the iron piece to vibrate electromagnetically to generate a buzzer sound BZ (first buzzer sound).
Figure).

If the switch operation is confirmed to be correct after the buzzer sound BZ sounds and the switch is turned off within the limited time T, the switch signal S1 is no longer output at this point (FIG. 2 (B)
(1)).

Upon detecting this, the switch control unit 2 stops outputting the confirmation signal S2 (FIG. 2 (B) (2)).

For this reason, the buzzer control section 3 stops outputting the buzzer drive signal S5 (FIG. 2 (4)).

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

The device section 5 which has received the operation control signal S4 receives the switch signal S1 and starts operation.

If you turn on the switch but do not notice an error in the operation, or if another object touches the switch and keeps on, and you do not notice it.

In this case, the switch signal S1 continues to be output even after the delay time t1 has elapsed and the limit time T has elapsed (FIG. 2 (C)).
(1)).

In this case, the switch control unit 2 outputs a warning signal S3 having a short pulse width together with a confirmation signal S2 having a pulse width T (FIG. 2 (C) (2)), and a buzzer which inputs both S2 and S3. -Since the control unit 3 outputs the buzzer drive signal S5 (FIG. 2 (C) (4)), the buzzer unit 4 sounds them with a buzzer sound BZ.

At the same time, the switch control unit 2, which has detected that the confirmation signal S2 has exceeded the limit time T, determines that the operation is erroneous and does not output the operation control signal S4 (FIGS. 2C and 3).

As a result, the switch signal S1 is not taken into the device 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 step P1, it is determined in step P2 whether the delay time t1 has elapsed.

If the delay time t1 has elapsed, it is determined in step P3 whether the switch signal S1 is still being input.

Release the switch before the delay time t1 elapses, and switch signal S1
If is not entered, you will immediately notice a mistake in the switch operation, so no confirmation sound is required,
In order to make the switch operator thoroughly aware of this, it is preferable to generate a switch rejection sound as shown in step P11.

If it is determined in step P3 that the switch signal S1 has been input even after the elapse of the delay time t1, the process proceeds to the next step P4 to generate a confirmation sound.

In Step P5, it is determined whether or not the limited time T has elapsed. In Step P6, it is determined whether or not the switch signal S1 can be input within the limited time T.

When the operator hears the confirmation sound and thinks that the switch operation is correct and releases the switch within the limited time T, the next step P7
In step, while taking in the switch signal S1,
In P8, it is preferable to generate a switch take-in sound to ensure that.

In the last step P9, the operation control signal S4 is output, and the device section 5 is operated.

However, in step P6, if the switch is kept pressed even after the lapse of the limited time T, a warning sound is generated in step P10, and preferably, in step P11, a switch rejection sound is generated, so that the operator is notified. And the switch signal S1 is not taken in.

[Effects of the Invention] As described above, according to the present invention, when the switch signal S1 is input and the switch signal S1 is continuously input even after the delay time t1 has elapsed, the confirmation signal S2 is output and the When the switch signal S1 is not input within the time T, the operation control signal S4 is output after the confirmation signal S2, or when the switch signal S1 is continuously input after the lapse of the limited time T. Outputs a warning signal S3 after the confirmation signal S2, inputs the switch signal S1, and operates the confirmation signal S2 and the warning signal S3 when the switch signal S1 is not generated within the delay time t1. The switch control unit 2 that does not output the control signal S4 and the confirmation signal S2 or the confirmation signal S2 and the warning signal S3 are input, and a buzzer-drive signal S5 corresponding to each signal is input.
Buzzer control unit 3 for outputting the buzzer drive signal
A buzzer section 4 for inputting S5 and outputting a buzzer sound BZ. A audible confirmation sound is generated when the switch for preventing erroneous operation and the switch are pressed and kept pressed after the delay time has elapsed. At the same time, when the switch is released within the limited time, the switch signal is captured, or when the switch is kept pressed after the limited time has elapsed, a warning sound is emitted, and when the switch is pressed and released within the delay time, Is
Technical measures have been taken in which a switch signal is not taken in, a switch taking method.

Therefore, a buzzer sounds a few seconds after the switch is pressed. If the switch operation is correct, the switch is input by releasing the switch a few seconds later.

On the other hand, even if the buzzer sounds, if the switch is pressed for a long time without noticing the error of the switch operation, a warning sound is further sounded and no switch input is performed.

For this reason, the technical effect of preventing erroneous operation of the switch and facilitating the switch operation while ensuring the reliability and safety of the measurement is achieved.

That is, by requesting the two operations of pressing and releasing the switch, it is possible to confirm the correctness of the switch operation and prevent an erroneous operation such as accidentally touching the switch or keeping the switch pressed.

Furthermore, it is an interactive switch operation with a device that confirms a buzzer sound for two operations of turning on and off the switch, and the operation is extremely easy and does not cause erroneous operation.
When applied to recent soft touch switches, the advantage becomes even more pronounced, and there are various additional effects that the switch operation can be performed while operating other devices because the buzzer sound is used.
