Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an alarm device that has recently been applied in general industry, and more particularly to an alarm device that issues an audible alarm.

[Technical background of the invention and its problems]

Unlike conventional visual warning systems, audio warnings do not pose the risk of people not noticing the warning even if they are doing other tasks, and they also provide the same amount of information to a large number of unspecified people at once. 4 from being able to communicate! This is a method of warning communication that has recently been attracting attention. However, in conventional applications, the audible alarm is only temporary, and one alarm message usually lasts for 10 to 20 seconds, and if another output request occurs while the message is being output, it is repeated until the end of the message. If there is a strong correlation between messages, requests for the same message will overlap, resulting in problems such as the same message being output many times9, and the reality is that its usage is limited. Met.

An example of a conventional audio warning device will be explained. 1st
The figure shows an example of the configuration of a conventional audio warning device. The audio alarm request event signal l (many) is directly transmitted to the audio alarm device 2V.
c is input, and the audio warning device 2 outputs the audio message previously stored in correspondence with the audio warning request event signal 1 to the audio output device 4 as the audio message signal 3, thereby issuing an audio warning. Consider, for example, a case where an audio warning device having such a configuration outputs event-based warnings having correlations as shown in FIG. 3. FIG. 3 is a one-event correlation diagram (example), and when event A20 occurs, event B21 and event E24 always occur. When event B21 occurs, event C22 and event D
23 occurs. When event E24 occurs, event F25 occurs. Furthermore, it is shown that event C22, event D23, and event F25 can each occur independently and independently of other events. Each of these correlated events is an audio warning output request signal, and is event A20, event B21, event C22,
Event D23 corresponds to the same message MIK, and event E
24. Assuming that event 25 corresponds to another identical message M2, if the terminal events of event C22, event D23, and event F25 occur, the message corresponding to each occurred event (in this case, Ml or M'2)
is output and there is no problem, but when event B21 occurs, event 022 and event D23 also occur, so the message M1 corresponding to each is returned, and in this case, Ml, M
The message ``l'', ``ml'' is repeated three times. Also, event A
20 occurs, the details are omitted, but Ml , Ml ,
Ml, M2.

A message called M2 will be output.

This is a fatal flaw from the perspective that voice messages are not practical unless they are concise and clear. or,
Since this is a redundant warning, even if another important message comes in while this message is being output, it will not be output immediately, leading to a delay in the warning and the possibility of causing a serious disaster.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and it investigates the correlation between events, increases the redundancy of output messages, and
It is an object of the present invention to provide an alarm device which considers the priority of events and actively outputs audible ones with high priority.

[Summary of the invention]

The purpose of the present invention is to, when an alarm generation request is issued to the device, check the priority of the request signal in the alarm decision sequence, select the one with the highest priority, and select the one with the highest priority. This is achieved by outputting a corresponding audio warning.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram of a warning device using audio according to the present invention. The audio warning request event signal 1 is constantly read into the request signal determining section 5. The request signal discrimination unit 5 detects a change in the audio alarm request event signal 1 (occurrence of an audio alarm output request) and sends an alarm discrimination request signal 6 to the alarm decision sequence unit 7.
Output.

In the alarm decision sequence section, the alarm discrimination request signal is 6V.
c From the included request event, the request event III [
Input the state of the event corresponding to the check event No. registered in advance corresponding to lV'c. In this case, the voice alarm request signal 1), and if the state satisfies the conditions, the alarm discrimination request signal is input. 6 is ignored and no audio output is performed.

In addition, if the conditions are not satisfied, an alarm determination request signal 61 is sent.
A voice output enable signal 8 specifying a message corresponding to C is output to the voice output control section 9. The audio output control unit 9 manages the audio output enable signals 8 from the alarm decision sequence unit 7 in the order of arrival and outputs the audio output request signal 10 to the audio alarm device 2 in order. is predefined in the audio output control unit 9 as the highest priority level.If the message is positive, the order of arrival is ignored and the audio output request signal 10 is output to the audio alarm 2 with the highest priority.

The voice warning device 2 extracts message information predefined within the voice warning device from the message floor given by the voice output request signal 10vc, and outputs a voice message signal 3 to the voice output device 4.

Next, the operation of the alarm decision sequence section 7 will be described in detail. Using the event correlation diagram in Figure 3 as an example, event 022
The case will be explained below. In the decision condition section corresponding to event 022 of the decision sequence section 7, the number of event B21 located above it is defined in advance. If event 022 occurs now, the request signal discriminator detects event 02.
2 and outputs an alarm discrimination request 6 to the alarm decision sequence section 7. Alarm decision sequence section 7
In this case, event B is taken out of the above-mentioned condition.
1, and if it is true, that is, in this case, the event is 0.
Since 22 is not an isolated occurrence, the request is ignored. If it does not hold true, it is determined that event 022 occurs independently, so processing is performed to output audio as requested.

In this way, by defining judgment conditions according to the event correlation diagram and message grouping, it becomes possible to eliminate the output of unnecessary messages. Incidentally, although Fig. 4 shows the higher order event B21 in event 022 of the decision sequence section of the present invention, similarly, for other events, if you always look at the conditions for the establishment or failure of the event one level above the own event, the function will be sufficient. Since the condition is satisfied, there is no need to include higher-level events further back in the condition.

According to the present invention, when applying the event relationship shown in the correlation diagram of FIG. Event B21-+Event A20. Event D23→Event B21. If the condition is defined as event 'F25→event E24, when event C22, event D23, and event F25 each occur independently, the corresponding message M1 or M2 will be output. Further, even if event A20 occurs and all the events included in this event correlation diagram occur, only messages M1 and M2 are outputted due to the operation of the present invention described above. (Ml or M2 repeat generation is not performed.) The decision sequence unit 7 may be implemented by any device that can store data and perform logical judgment. (For example, diode matrix, relay sequence, microphone four computer, etc.) [Effects of the Invention] As described above, according to the present invention, the following effects are obtained.

■ A simple and clear voice warning device can be obtained.

■ Priority management is clearly carried out.

■ Logic judgment can be freely combined without relying on external circuits, making it highly versatile.

etc. can be mentioned.
