Description

[Detailed Description of the Invention] The present invention relates to a magnetic drum type voice response device, and more specifically, when an abnormality or failure occurs in the environment or equipment, an alarm and information corresponding to the abnormality or failure are transmitted by voice. The present invention relates to a voice response alarm device that allows a response to be made.

Audio output devices using magnetic drums are conventionally known and used in various announcement systems. This device divides the magnetic recording medium layer on the outer peripheral surface of a magnetic drum into a large number of tracks, and a magnetic head that performs a track selection operation randomly accesses each track, and records data on a predetermined track through the magnetic head. The device is configured to play back audio information. A voice response device using this type of voice output device detects the occurrence of an abnormality or failure using sensors placed at multiple monitoring points of the environment or equipment, and records corresponding signals using the obtained sensing signals. The track audio signal is selectively broadcast. In this case, the broadcast content is generally one of the following. One method is to record either an alarm sound or audio information related to abnormalities or failures in each truck, and depending on the sensor output, the alarm sound recorded in the corresponding truck or the abnormal fault is recorded. The configuration is such that either one of the contents is broadcast, and the other one is to record an alarm sound on each track, followed by the contents of the abnormal failure corresponding to the sensor, and broadcast the alarm sound according to the sensor output. First, an alarm is sounded, and then the details of the abnormal failure are broadcast.

However, with the former configuration, if only the content of the failure or abnormality is broadcast, maintenance personnel or operators located far away in a noisy environment may not notice the occurrence of the failure. be done. Furthermore, if only a loud warning sound is broadcast, although it can be detected from a distance, maintenance personnel or operators have to investigate abnormalities and failures one by one in order to deal with the problem, resulting in the disadvantage that maintenance is troublesome and time-consuming.

In addition, in the case of the latter configuration, if the duration of the alarm sound is long, maintenance personnel and operators will not be able to take action until the alarm sound has finished broadcasting in order to know the details of the failure or abnormality. If the duration of the alarm is short, the alarm may have ended and part of the details of the failure or abnormality may have already been broadcast by the time maintenance personnel or operators arrive at the scene, resulting in a lack of information about the details. It interferes with coping. In any case, this configuration has had various problems, such as differences in the environment or the positional relationship between the equipment and the maintenance person or operator.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the conventional technology, and even in a noisy environment, alarms of abnormalities and failures can be transmitted far away, allowing maintenance personnel and operators to reliably detect them. An improved voice response alarm system that enables maintenance and operation to be carried out smoothly without time loss, as the operator can immediately listen to voice information corresponding to the sensor output when reaching the equipment, etc. Our goal is to provide the following.

The present invention, which was devised to achieve such a purpose, is equipped with a magnetic drum on which audio information is recorded on each of the tracks of a plurality of sensors, and outputs the corresponding audio information in response to the output of each sensor. In the apparatus, the magnetic drum has a recording form in which an alarm sound is recorded on at least one track thereof; This magnetic drum type voice response alarm device is equipped with a switch mechanism for switching from the information track to the information track corresponding to each sensor output, and is configured so that the alarm sound track is selected and driven first when the sensor outputs.

Hereinafter, the present invention will be explained in more detail based on the drawings. The drawing is a block diagram showing an embodiment of the voice response warning device according to the present invention. As is clear from the figure, the voice response warning device according to the present invention includes a large number of sensors 1, a magnetic drum type voice output device 2, and a speaker 3.
In this embodiment, there are 15 sensors 1 (their outputs are represented by S ₂ to _{S 16} , respectively), and each sensor 1 is installed at each monitoring point of the environment or equipment. In addition, the audio output device 2
The magnetic drum has at least one more recording track than the number of installed sensors 1 (here, their input ends are represented by T ₁ to T ₁₆ ), and its basic configuration is based on the conventionally known structure. It may be the same as that. In other words, the magnetic recording medium layer on the outer peripheral surface of the magnetic drum is divided into 16 tracks, and a magnetic head that performs a track selection operation randomly accesses each track, and data is recorded on a predetermined track via the magnetic head. The configuration is such that the speaker 3 is driven by reproducing audio information.

Now, in the present invention, all the outputs of a large number of sensors 1 are logically summed at the logical sum gate 4, and the output is sent to the first interlocking switch 6 via one _SW1 .
It is supplied to the selection input terminal _T1 as a track selection signal, and is also inputted to the audio output device 2 via the second switch 7 as an activation signal. Also,
The output of each sensor 1 is inputted via an AND gate 5 to each track selection input terminal T ₂ to _{T 16} of the audio output device 2 as a selection signal for the corresponding track. Further, the other input terminals of each of the AND gates 5 are connected in common and grounded via the remaining portion _SW2 of the first switch 6. Here, the magnetic drum in the audio output device 2 has a first track on which a loud warning sound that can be easily sensed even in a noisy environment is recorded, and the remaining tracks have the output S of the sensor 1 recorded thereon. ₂ ~ _S16
Information corresponding to each abnormality or failure, that is, information about the location of each abnormality or failure, or information about measures to deal with the abnormality or failure, etc., is recorded.

The operation of this apparatus configured as described above is as follows. When the occurrence of an abnormality, failure, etc. is detected by the sensors 1 placed in various places, the corresponding sensor 1
Output signals S ₂ to S ₁₆ result. In this embodiment, the outputs S ₂ to _{S 16} of the 15 sensors 1 are at H (high) level when operating and at L (low) level when not operating, and the audio output device 2 operates at L level. It is assumed that When the sensor 1 is not in operation, all outputs of the sensor 1 are at the L level, therefore the output of the OR gate 4 is at the H level, and the start signal input and track selection inputs _T1 to _T16 are all at the H level, so the audio output device 2 doesn't work. On the other hand, if any of the outputs S ₂ to S ₁₆ of sensor 1 operates,
The output of OR gate 4 becomes L level, the start signal input also goes to L level, and the first track selection input
_T1 also becomes L level. However, since one switch SW ₂ of the first interlocking switch 6 is closed, the other track selection inputs T ₂ to T ₁₆ are all at H level because the AND gate 5 is closed. 2 will broadcast the content of the first track, that is, the alarm sound. This state continues until a maintenance person or operator rushes over and operates the first interlocking switch 6 to open it. In other words, no matter which sensor's output occurs, the first
track will be selected and the alarm will continue to sound. If the activation signal input is at L level, the magnetic drum of the audio output device 2 continues to rotate. When SW ₁ and SW ₂ are opened by operating the first interlocking switch 6, the common input of the AND gate 5 becomes H level, so only the track input where sensor 1 is operating becomes L level. The corresponding track will be selected. In addition, the first track selection input
Since SW ₁ is open _, T1 becomes H level. Therefore, no alarm sound is generated. However, the activation signal input remains at the L level as long as any sensor 1 is operating, and the magnetic drum continues to rotate. Therefore, the audio output device 2 repeatedly broadcasts information regarding the operating sensor in response to the track selection input signal from the sensor 1. This allows the maintenance person or operator to know at an appropriate time the occurrence of an abnormality or failure, its details, and how to deal with it. After the abnormality or failure is resolved, the output of each sensor 1 becomes L level, so it is sufficient to close the first interlocking switch 6 again.

If multiple sensors operate simultaneously, the content of one sensor is resolved by prioritizing the selection functions in the audio output device 2 (for example, selecting in order from the lowest track number), and the first
It is also possible to close the interlock switch 6 to listen to the next sensor content, obtain information about that sensor, and take countermeasures, or it is possible to use a function in the audio output device to receive sensor outputs from multiple sensors at the same time. In this case, information regarding multiple inputs may be broadcast sequentially in accordance with the priority order, and the broadcast may be repeated. Such functions can be performed by software using a microcomputer within the audio output device.

The second switch 7 listens to the information about the activated sensor, and then the audio output device repeats broadcasting as long as the startup input signal is at L level, so it can cut off the startup signal if it feels noisy. It is for the purpose of

Since the present invention is a voice response alarm device configured as described above, it is able to send notifications even in a noisy environment over a long distance, thereby reliably communicating the occurrence of abnormalities or failures in the environment or equipment to maintenance personnel or operators. At the same time, by operating a switch when the maintenance personnel or operators arrive at the equipment, they can immediately obtain the necessary information without wasting time, so they can quickly and reliably respond to abnormalities and failures. Since the alarm sound uses only one track common to many sensors, the number of required tracks increases by only one, and the large size of the equipment The practical effects are extremely large, such as being able to avoid oxidation.
