Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a self-fire alarm system.

[Prior Art] Conventionally, in the self-fire alarm system, when there is an alarm, there is a system which displays an alarm time.

[Problems to be Solved by the Invention] However, what is necessary when an actual fire occurs is to check the site immediately and take measures. However, in the conventional time display, it is necessary for a person who manages the passage of time to decode the displayed time.

In addition, since the time is displayed, time display adjustment for time adjustment, time synchronization with equipment mainly for time management, and the like are required, and there has been a problem that maintenance such as time adjustment is troublesome.

The present invention provides a self-fire alarm system in which the elapsed time from the alarm can be understood at a glance, a fire response can be easily performed, no maintenance such as time adjustment is required, and no means for time adjustment is required. In particular, it is an object of the present invention to provide a self-fire alarm system capable of displaying an elapsed time for each alarm and managing a plurality of locations at once.

Means for Solving the Problems According to the present invention, when an alarm is issued from a fire detector, a timer means for counting the elapsed time from the time of the alarm, and a display for displaying the elapsed time counted by the timer means every moment In particular, the invention according to claim 2 is characterized by comprising display means for displaying the elapsed time for each of a plurality of alarms when there is a plurality of alarms. It is characterized by having display means for displaying the elapsed time with numbers,
A display means for graphically displaying the elapsed time according to claim 4 in an analog manner is provided.

[Accordingly, when an alarm is issued, the timer means is operated to simultaneously display the elapsed time counted simultaneously by the display means. By this display, the administrator can grasp the elapsed time from the alarm.

If the elapsed time is displayed for each of a plurality of alarms, the elapsed time from each alarm can be grasped, and the progress of the fire can be easily grasped.

EXAMPLES The present invention will be described below with reference to examples.

FIG. 1 shows the overall configuration of the self-fire alarm system,
A line 3 connected to the fire detector 2 ₁ ... from receiver 1, Bohai smoke device 4 and the control line 6 for controlling the zone bell 5 is derived.

The fire detectors 2 ₁ are polled by the time-division multiplex transmission signal sent from the receiver 1 through the line 3 to send sensing information to the receiver 1, or when the fire is detected, the line 3 is short-circuited to reduce the line current. It is of an on-off type that flows to the receiver 1 side, and in any case, the sensing information can be transmitted to the receiver 1. The receiver 1 determines an alarm for each area where the fire detectors 2 ₁ ... Are arranged based on the sensing information. When an alarm is issued, the receiver ₁ controls the control line 6 based on the alarm by, for example, time division multiplex transmission. The signal is used to operate the district bell 5 connected to the terminal device 7 ₁ . This monitoring control is performed in the same manner as the conventional self-fire alarm system. However, in the self-fire alarm system according to the present invention, when the alarm is determined by the receiver 1, the timer 8 starts operating simultaneously with this determination. Is provided in the receiver 1 as shown in FIG. 2, and this timer sends count value data that is being counted every moment to the display device 9 provided in the receiver 1.

The display device 9 numerically displays the elapsed time corresponding to the count value data on a predetermined portion of the display 10 such as a CRT.

Here, the timers 8 are provided corresponding to the respective districts, and if there is an alarm corresponding to the respective districts, the respective timers 8 are operated, and the elapsed time of the operating timers 8 is "1 hour 10 minutes".
When the numerical value indicating the elapsed time and the number of each district are displayed on the display 10 as shown in FIG. 3, the manager can grasp at a glance the elapsed time from the alerts at a plurality of places. . Of course, the display location may be set to one location, and the display area may be sequentially and cyclically switched by operating a feed switch (not shown).

FIG. 4 shows a flowchart relating to the display processing of the elapsed time from the alarm, and the display is performed until a recovery operation is performed as shown in this flowchart.

Although the elapsed time is indicated by a numerical value, the elapsed time may be indicated by a graphic such as a bar graph 11 as shown in FIG.

In addition to the CRT, a liquid crystal display panel or a plasma display may be used as the display 10. In the case of performing the analog display, a bar graph display using a light emitting diode may be used.

[Effects of the Invention] The present invention includes a counting means for counting the elapsed time from the time of the alarm when an alarm is issued from the fire detector, and a display means for displaying the elapsed time counted by the counting means. As a result, the time elapsed since the alarm was issued can be grasped at a glance by the administrator.
In addition, since it is not a time display, there is an effect that maintenance at a normal time such as time adjustment is not required, and a means for time adjustment and a complicated clock circuit are not required.

In particular, according to the second aspect of the present invention, when there are a plurality of alarms, the display means for displaying the elapsed time for each alarm is provided, so that the elapsed time of the alarm at a plurality of locations can be grasped. This has the effect of making it easier to grasp the degree of progress.
