Abstract

PURPOSE:To prevent a buzzer from being continuously driven by providing an error alarm part in a circuit for generating an alarm at the time of detecting an error with plural counter parts corresponding to the sorts of errors and outputting an alarm only when the values of the counters reach a certain value. CONSTITUTION:At the time of detecting an error, an error detecting part 1 inputs an error signal to an error alarm part 4. The alarm part 4 is provided with plural counter parts 41 corresponding to the sorts of errors, and at the time of inputting an error signal, '1' is added to the counter concerned and the buzzer is driven through a buzzer control part 2 to output an alarm. The alarm is reset to stop the buzzer and recovery is started. When the error detecting part 1 continuously outputs the same kind of error detecting signal, '1' is added to the contents of the counter part 41 and the count value goes '+2', and at that time, the buzzer control part 2 does not drive the buzzer 3. Consequently, the buzzer 3 can be prevented from being continuously driven until the removal of the cause of the error.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an error reporting system that periodically detects an error, sounds an alarm, and stops sounding the alarm once the alarm is reset.

[Conventional technology]

Fig. 3 is a block diagram of a conventional error reporting system. In the figure, 1 is an error detection unit that detects errors, 2 is a buzzer control unit that controls the sound of a buzzer that constitutes an alarm, and 3 is an alarm unit. 4 is an error reporting section that instructs the buzzer control section to sound the buzzer based on the output of the error detection section 1, and 5 is a reset section that stops the buzzer sounding.

Next, the operation will be explained based on FIG.

When an error occurs, the error detection section 1 detects the error and outputs a signal to the error reporting section 4 indicating that an error has occurred.

Based on the signal from the error detection section 1, the error reporting section 4 outputs a signal instructing the buzzer control section 2 to sound a buzzer. This signal from the error reporting section 4 causes
Buzzer control unit 2 sounds buzzer 3. Here, when a person operates the reset unit 5 and outputs a reset signal to the buzzer control unit 2 to stop the buzzer sounding, the buzzer control unit 2 stops the buzzer 3 from sounding.

After the buzzer stops sounding in response to the reset signal, if the same error as the one detected above occurs again, the buzzer 3 will sound again in the same manner as above.

[Problem to be solved by the invention] Since the conventional buzzer reporting method is configured as described above, there is a problem that the buzzer continues to sound and does not stop while the same error occurs even if the buzzer is reset. There was a point.

This invention was made to solve the above-mentioned problems, and once the alarm device consisting of 11A and 11 is reset, while the error that caused it occurs, the alarm device due to that error will be reset. The purpose is to stop the noise.

(Means for Solving the Problem) Therefore, the error reporting system according to the present invention is provided with a counter section 41 consisting of a plurality of counters, and increases or decreases the count of the counter corresponding to the occurrence of each error, so that the value of the counter increases or decreases. This system is characterized in that an alarm (buzzer 3) sounds only when a certain value is reached.

[Effect]

When an error occurs, a counter corresponding to each error occurrence is increased or decreased. Then, the alarm is sounded only when an error occurs and the value of the counter corresponding to the error occurrence reaches a predetermined value ((α).

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. Note that the same components as those in the prior art are given the same numbers and their explanations are omitted.

FIG. 1 is a block diagram showing an embodiment of the present invention, and in the figure, reference numeral 41 denotes a counter section comprised of a plurality of counters provided within the error reporting section 4. As shown in FIG.

Next, the operation will be explained with reference to FIG.

When an error occurs, the error detection unit 1 detects the error and outputs a signal to that effect to the error reporting unit 4.

The error reporting section 4 is a counter section 4 within the error reporting section 4.
The count value of one of the plurality of counters corresponding to the error is increased by one.

If the count value is 1, the buzzer control unit 2
Outputs a signal instructing the device to sound.

At this time, the buzzer control section 2 sounds the buzzer 3. When a person operates the reset section 5 in response to the sound of the buzzer 3, the buzzer control section 2 stops the sound of the buzzer 3 based on the output signal from the reset section 5.

If the error detection section 1 detects the same error again, the error reporting section 4 increases the count value of the counter corresponding to the error in the counter section 41 by 1 based on the output signal from the error detection section 1.

Since the count value is 1 due to the previous error detection, the count value becomes 2 this time, and the error reporting unit 4 does not output a signal instructing the buzzer control unit 2 to sound the buzzer.

On the other hand, if the error that has occurred is repaired and errors due to the same cause no longer occur, the count value is reset to 0. Since this process is repeated, the buzzer will only sound once in response to an error caused by one cause. Therefore, when the buzzer is sounding due to a certain cause, if you reset the buzzer once, the buzzer will sound again while the error continues.
The sound never goes away. In this way, the buzzer can be reset without fail.

In the above embodiment, a counter section 41 is provided in the error reporting section 4.
Although we have shown an example in which the error reporting section 4 increases the count value in response to the signal from the error detection section 1, a counter section 41 is provided in the error detection section 1, and the error reporting is performed only when the counter value is a certain value. A signal to that effect may be output to section 4.

In this way, it is not necessary to provide the counter section 41 in the error reporting section 4, and it may be provided in the buzzer control section 2.
Alternatively, they may be provided separately.

As a result, the buzzer should sound only when the counter value is a certain value and an error is detected.

Further, when an error is detected, the same effect can be obtained by decreasing the count 110 instead of increasing it.

Further, as a method of assigning a counter to each error, for example, a table showing the correspondence between the location where an error occurs and the counter may be prepared.

Also, alarms are not limited to buzzers, but also bells.

A flashing indicator or the like may also be used.

〔Effect of the invention〕

As explained above, according to the present invention, a counter unit consisting of a plurality of counters is provided, and the count of the counter corresponding to each error occurrence is increased or decreased, and only when the counter value is a certain value. The alarm now sounds, so when the alarm is sounding due to an error, once the alarm is reset, the alarm will not sound again while the error continues to occur, so the error will be fixed. The effect is that the alarm will no longer go off without going off until the cause is removed.
