Description

[Detailed description of the invention] This invention displays a message in text in response to an alarm signal such as a fire, and when multiple alarm signals are received, the number of display sections corresponding to each alarm signal is lit to display multiple messages. The present invention relates to an alarm display device that lights up a display section corresponding to an alarm signal among sections, and causes the display section to blink for an alarm signal that is displaying characters.

Conventional alarm indicators of this type store a text message containing the alarm content corresponding to each incoming alarm signal, and when multiple alarm signals are received, the first alarm signal is In addition to displaying the corresponding text message, by operating a changeover switch, corresponding texts for the second and subsequent alarm signals are also displayed in sequence.

However, upon receiving multiple alarm signals,
By simply turning on the indicator lamp indicating that the number of alarm signals received is 2 or more, you can operate the switch several times to see what other alarm signals are being received while the text message is being displayed. If you repeatedly display text messages for each alarm signal in sequence, it will be difficult to immediately tell which alarm signal the text message being displayed corresponds to.
There is also the problem that it is not possible to know how many alarm signals have been received.

The present invention has been developed in view of the above-mentioned problems, and when multiple alarm signals are received, it is possible to easily identify the correspondence between the text message being displayed and the number of alarm signals being received. An object of the present invention is to provide an alarm display device that makes it easy to determine how many alarm signals are currently being received.

In order to achieve this purpose, the present invention provides a number of display sections corresponding to the number of alarm signals being received, and when multiple alarm signals are received, the display section corresponding to the alarm signal being received is lit up and The text message corresponding to the first received alarm signal is read from the memory and displayed in text. Each time this text display is switched, the number of outputs is counted by a counter, and based on the count output of the counter, the text message being displayed in text is responded to. The display unit blinks, and the reception status of the alarm signal can be determined from the number of display elements that are lit, and the number of the alarm signal being displayed in text can be determined from the blinking display unit. This is how it was done.

Yes, the text number from the alarm processing circuit 18 is input, and the reception time information of the same text number is given to the time display circuit 8, so that the time display section 2 displays the reception time of the alarm signal.

Next, the operation will be explained with reference to the program flow diagram of FIG.

First, block a is the initial value setting, and the first block of the alarm processing circuit 18 is set at the same time as the alarm indicator is powered on.
Set the count value (reception count number) of the counter to “0”
Then, the count value (switching count number) of the second counting section is set to "1". Block b monitors the alarm signal arriving at the input scan circuit 16, and block c monitors the input scan circuit 16.
If there is no alarm signal input, block B is activated again.
The system then returns to monitor the incoming alarm signal.

First, when the first alarm signal is received and input to the input scan circuit 16, the process proceeds to block d, where the text number output from the input scan circuit 16 is memorized in the alarm processing circuit 18, and the first counting section The reception count number is counted up and the count number is set to "1".

In block e, it is determined whether the received count value is "1" or not, and since the first alarm signal is input and the count value is "1", the process proceeds to block g. In block g, the text memory circuit 19 operates by inputting the text number corresponding to the switching count from the alarm processing circuit 18, and sends the text code corresponding to the text number of the first report to the text display circuit 5. The text message is output and displayed on the character display section 1 in characters. Furthermore, in block h, the receiving lamp display circuit 11 is driven by the operation of the display control circuit 23 according to the output of the display counter circuit 20, and the display elements corresponding to the count number "1" of the display counter circuit 20 are made to blink. In block i, it is checked whether or not a changeover switch for changing the display contents provided on the operation section 4 has been operated.If the changeover switch has not been operated, the process advances to block j and it is checked whether or not a recovery operation has been performed. If the recovery operation is not performed, proceed to block b and monitor the input of the alarm signal; if the recovery operation is performed, proceed to block a.
Return to and set the initial values.

Next, the operation when a plurality of alarm signals are received will be explained. In block c, for example, when a second alarm signal is input to the input scan circuit 16 following the first alarm signal, the process proceeds to block d, where the sentence number corresponding to the first alarm signal output from the input scan circuit 16 is input. is stored in the alarm processing circuit 18, and the first counting section and reception number counter circuit 22 operate to increase the count value to "2".
At this time, the text number corresponding to the second report stored in the alarm processing circuit 18 is determined by the switching count of the second counting section and is not output to the text memory circuit 19, so the display counter circuit 20
The displayed count continues to be "1". In the judgment in block e, the reception count number has increased to "2", so the process goes to block f, and the display control circuit 23 operates according to the output of the reception number counter circuit 22 to display the first and second reports. Turn on the display element for the eyes. Further, the process advances to blocks g and h, and since the text memory circuit 19 continues to output the text corresponding to the first alarm signal, the text display circuit 5 continues to display the text corresponding to the first alarm signal. At the same time, the receiving lamp display circuit 11 also has the first
The display element corresponding to the information flashes. Now, when a command signal for switching the display content is sent to the display content switching circuit 21 via the interface 15 by operating the changeover switch provided on the operation unit 4, the display content switching circuit 21 operates and the alarm processing circuit 18 the second of
The switching count of the counting section is counted up to "2", and the text number corresponding to the second alarm signal stored in the memory section is forcibly outputted to the text memory circuit 19, and the text memory circuit 19 is activated. The display counter circuit 20 is operated by the output from 19. That is, by operating the changeover switch of the operating section 4 in block i, the display counter circuit 2 advances to block k.
The switching count number of 0 is counted up to "2". Furthermore, proceeding to block 1, the switching count number "2" of the second counter section is compared with the reception count number "2" of the first counter section, and since the switching count number is not larger than the reception count number, block g ,h
Then, the text corresponding to the second alarm signal is displayed on the character display section 1, and the display element of the receiving light 3 corresponding to the second alarm signal is blinked.

In this state, when the changeover switch is further operated using the operation unit 4, the process proceeds from block i to block k, and the changeover count is further incremented to the count number "3". In block 1, since (switching count number "3")>(receiving count number "2"), the program proceeds to block m, resets the switching count number to "1", and proceeds to blocks g and h. block g,
In h, the switching count number = "1", that is, the text corresponding to the first alarm signal is displayed, and the alarm processing circuit 1 is displayed in response to the switching count number "1".
8 sends a reset signal to the display counter circuit 20. After being reset, the display counter circuit 20 inputs a signal from the text memory circuit 19 to blink the display element corresponding to the first report.

Next, the time display operation will be explained. The clock circuit 24 counts the time based on a predetermined oscillation output from the oscillation circuit 26, and stores the received time memory circuit 2.
5 is constantly given time information. The reception time memory circuit 25 stores the reception time of the alarm signal together with the document number corresponding to the alarm signal input to the input scan circuit 16, and stores the reception time of the alarm signal.
When the text number is output from 8, the reception time information of the alarm signal corresponding to the output text number is sent to the time display circuit 8. Therefore, the alarm processing circuit 18
By operating the text memory circuit 19 and the reception time memory circuit 25 in synchronization with the output from the
In synchronization with the text display in the text display circuit 5, the time display circuit 8 displays the reception time of the corresponding alarm signal while the text is being displayed.

Note that a display element that displays numbers may be used as the reception light 3 that displays the reception status of the alarm signal and the text being displayed.

As explained above, according to the present invention, when multiple alarm signals are received, the display section (display element) according to the number of received alarm signals lights up, and the text corresponding to the alarm signal received in response to a command from the operation section is displayed. are displayed in sequence, and the display section (display element) corresponding to the alarm signal being displayed is made to blink, so that the number of received alarm signals and the text being displayed correspond to the report number. The effect is that it is possible to easily identify whether the signal is an alarm signal or not.
