Description

The present invention relates to a P-type fire alarm facility.

  In a fire receiver and a display device in a conventional P-type fire alarm facility, the room number display score at the time of a fire is defined in advance in a memory such as a ROM (for example, see Patent Document 1).

  Here, the “room number display score” is the maximum number of points at which the room number can be displayed on the room number display section.

  FIG. 5 is a flowchart showing the setting operation of the room number display score at the time of fire in the conventional P-type fire alarm system PS11.

  The conventional P-type fire alarm system PS11 sets the room number display points at the time of fire for the fire receiver, and also sets the room number display points at the time of the fire for the display device separately from the settings for the fire receiver. Set.

  First, the target of setting the room number display point at the time of fire is determined (S10), and when setting the room number display point at the time of fire for the fire receiver, the fire receiver is turned off (S11), for the power source not shown The LED is turned off, and it is selected whether to set “2nd report setting” or “20th report setting” (S12). When “2 report setting” is selected in step S12, the room number display score at the time of fire is set to “2 report setting” (S13). Then, the fire receiver is turned on (S14) and is normally monitored (S15). By this normal monitoring, a fire receiver power lamp (not shown) is lit in green.

  In step S12, in the case of “20 report setting”, the room number display point at the time of fire is set to “20 report setting” (S16). Then, the fire receiver is turned on (S14) and is normally monitored (S15). By this normal monitoring, the power lamp of the fire receiver (not shown) is lit in green.

  On the other hand, when setting the number of room number display points at the time of a fire for a display device (S10), one display device (the display device) of a plurality of display devices is turned off (S21), and a power LED (not shown) is turned off. Then, it is selected whether to set “2 reports” or “20 reports” (S22). When “2 report setting” is selected in step S22, the room number display score at the time of fire is set to “2 report setting” (S23). Then, the display is turned on (S24), and is normally monitored (S15). By this normal monitoring, a power lamp of a display (not shown) is lit in green.

  When “20 report setting” is selected in step S22, the room number display score at the time of fire on the display device is set to “20 report setting” (S26). Then, the display is turned on (S24), and is normally monitored (S15). By this normal monitoring, a power lamp of a display (not shown) is lit in green.

For other display devices, the operations of S21 to S24 and S26 are repeated for each display device.

  By the way, in the conventional P-type fire alarm system, it is sufficient to provide only one fire receiver. However, a plurality of display devices are provided as necessary, and in some cases, several tens of devices are provided. . Since it is necessary to set the number of room number display points in the fire in the same number as the number of display units, it is necessary to set the room number display points in the fire several times or several tens of times. There is a problem that it is complicated.

  In addition, the conventional fire receiver is installed in a building such as a disaster prevention center, while the fire indicator is installed in each site (for example, in front of an elevator on each floor of the building). When the setting of the number of room number display points at the time of fire is changed after installation, the operator must always work on site, and there is a problem that the work is complicated.

According to the present invention, in the P-type fire alarm system, it is sufficient to set the number of display points of the room number at the time of the fire on the receiver side, no matter how many display devices are installed. An object of the present invention is to provide a P-type fire alarm facility in which the number of display points can be easily set.

The display operation unit 33 is a means for inputting a predetermined room number in the forward or backward direction from the panel surface of the display DP1.

  The memory 19 is a corresponding memory that stores a predetermined fire detector address and a predetermined room number in association with each other.

  The room number display point setting switch 21 has a first display point for displaying a room number in the event of a fire and a second display point for displaying the room number in the event of a fire, which is different from the first display point. One of the switches is selected, and the selected room number display point is set.

  The main control unit 17 associates the address of the predetermined fire detector input through the input unit in the receiver RE1 with the predetermined room number input through the input unit, and stores the corresponding memory. 19 is a writing means for writing to the corresponding memory 19 in response to the input of the room number display points by the room number display point setting switch 21.

  The room number display units 20 and 32 display the room number corresponding to the room in which the fire detector SE that has made a fire is installed.

  The room number display units 20 and 32 display the room number of the room in which the predetermined line is installed when a sensor of a line to which the predetermined room number is set, that is, a sensor having no address is notified. Is displayed.

  According to the configuration of the above-described embodiment, the room number display point setting switch 21 and the memory for storing the predetermined room number display points are all set on the receiver RE1 side, and the display DP1 holds the settings and display contents. Therefore, the display DP1 is simple and inexpensive.

  The room number display unit 20 is provided with a left display unit (not shown), a right display unit (not shown), a first switch (not shown), and a tenth switch (not shown), and the first switch and the tenth switch are displayed. This is an example of scrolling the room number. The room number display section 32 is provided with a forward switch SW1 and a reverse switch SW2 (not shown), which are examples of scrolling the room number.

  In Example 1, the first display score is fixed at 2 reports and the second display score is fixed at 20 reports, but fixed at 3 reports, fixed at 30 reports, etc. It may be. Further, the room number display point setting switch 21 does not select any one of the first display point and the second display point, but selects any one of the plurality of display points or sets the point. It may be.

  Next, the operation of the first embodiment will be described.

  FIG. 3 is a flowchart illustrating the setting operation of the room number display score at the time of fire in the first embodiment.

  In FIG. 3, only the display DP1 is shown as the display. However, in addition to the display DP1, a plurality of displays are connected to the fire receiver RE1, and the operations of the plurality of displays are displayed. The operation is the same as that of the machine DP1. That is, the operation of the other plurality of display devices is the same as the operation of the display device DP1.

  First, the fire receiver RE1 is turned off and the display device DP1 is turned off (S1). Since the power of the display DP1 is supplied from the fire receiver RE1, the power of the display DP1 is automatically turned off when the power of the fire receiver RE1 is turned off. The power supplies of displays other than the display DP1 are also turned off.

  Then, it is determined which of “2nd report setting” and “20th report setting” is executed as the room number display score at the time of fire (S2). When setting “2 report setting”, the room number display point setting switch 21 is turned OFF, thereby setting the room number display point at the time of fire to “fix 2 report” (S3).

  Thereafter, the power source of the fire receiver RE1 is turned on, and accordingly, the power source of the display device DP1 is turned on (S4). The power supplies of the display devices other than the display device DP1 are also turned on. As a result, normal monitoring is entered (S5), a power lamp (not shown) is lit in green, and the setting operation of the room number display point is completed.

  In addition, when “20 report setting” is set as the room number display point at the time of fire (S2), the room number display point setting switch is turned on, so that the room number display point at the time of fire is “20 reports”. It is set to “fixed” (S6).

  Thereafter, the power source of the fire receiver RE1 is turned on, and accordingly, the power source of the display device DP1 is turned on (S4). The power supplies of the display devices other than the display device DP1 are also turned on. As a result, normal monitoring is entered (S5), a power lamp (not shown) is lit in green, and the setting operation of the room number display point is completed.

  Here, in step 4, when the power of the fire receiver RE1 and the display DP1 is turned on, the fire receiver RE1 recognizes the number of display points selected from the state selected by the room number display point setting switch, and The selected display point is sent to the display device DP1, and when the display device DP1 receives the sent display point, it is set by the display point, thereby completing the setting operation of the room number display point.

  Note that “fix two reports” is a method in which two display units are provided on the room number display unit 20 such as a left display unit (not shown) and a right display unit (not shown), and two room numbers are displayed simultaneously. is there.

  In this case, the address displayed on the address display unit (not shown) provided on the board of the fire receiver RE1 or the room number corresponding to the line displayed on the line display unit (not shown) is displayed. And the corresponding room number flashes.

  “Fix 20 reports” can display room numbers for up to 20 reports in the room number display section.

  Next, in the first embodiment, a description will be given of a scrolling operation for sequentially sending and displaying a fire display when a fire is triggered by the fire display device DP1.

  FIG. 4 is a diagram illustrating display scrolling of the fire indicator DP1 in the first embodiment.

  Here, “20 reports fixed” is set as the room number display score, there are 3 fire reports, and for each room number (the room number of the room where the fire detector that has reported is set) Assume that the first report is “00101”, the second report is “00104”, and the third report is “00203”.

  Of the five digits of the room number, the upper three digits represent the number of floors. For example, “00101” represents the first floor, and the lower two digits represent the number on that floor. For example, “00101” represents the first number. The room.

  In this way, with the fire display device DP1 receiving three fire alarms, the room number display unit 32 displays the first room number on the left display unit 321 as shown in FIG. “00101” is displayed, and the second room number “00104” is displayed on the right display 322.

  Here, when a forward switch SW1 (a switch that functions as a forward scroll switch), which is provided in the display operation unit 33 and is not shown, is pressed, the display unit DP1 determines whether or not there is subsequent data of the fire alarm. As a result, the second room number “00104” is shifted to the left display unit 321 and the third room number “00203” is displayed on the right side. Appears in part 322 and is displayed.

  Then, when the forward switch SW1 provided in the display operation unit 33 is pressed again, the fire indicator DP1 asks the fire receiver RE1 again whether there is subsequent data of the fire alarm, and as a result, FIG. As shown in (3), the room number “00203” displayed on the right display unit 322 is displayed on the left display unit 321. The right display 322 is blank because there is no fourth report.

  Then, when the forward switch SW1 provided in the display operation unit 33 is pressed again, the fire indicator DP1 asks the fire receiver RE1 again whether there is subsequent data of the fire alarm, and as a result, FIG. As shown in (4), the first report is returned to the first report, the room number “00101” of the first report is displayed on the left display 321, and the second report “00104” is displayed on the right display 322. Is displayed again.

  Further, when a reverse switch SW2 (not shown) is pressed instead of pressing the forward switch SW1 provided in the display operation unit 33, a reverse display operation is performed. Similarly to the above case, the fire indicator DP1 performs a display operation based on the result of the inquiry to the fire receiver RE1.

  That is, as shown in FIG. 4 (1), when a reverse feed switch SW2 (a switch that functions as a reverse feed scroll switch) provided in the display operation unit 33 is pressed from the display state of the first report. As in the case shown in FIG. 4 (3), the room number of the third report, which is the final report data, is displayed, and the room number “00203” of the third report is displayed on the left display 321. A blank is displayed on the right display unit 322 so as to indicate that it is the final issue data.

  Then, when a reverse switch SW2 (not shown) provided in the display operation unit 33 is pressed again, the room number “00203” of the third report displayed on the left display unit 321 is displayed as in FIG. The second display room number “00104” is displayed on the left display unit 321.

  Further, when a reverse switch SW2 (not shown) provided in the display operation unit 33 is pressed again, the first room number “00101” is displayed on the left display unit 321 as in FIG. At the same time, the room number “00104” of the second report is displayed on the right display section 322.

  According to the above embodiment, in a P-type fire alarm system, if a room number display point at the time of a fire is set for a fire receiver, the number of room number display points at the time of a fire in the display unit connected to the fire receiver Is set automatically, it is only necessary to set the number of room number display points at the time of a fire, regardless of how many display devices are installed, and it is easy to set the number of room number display points at the time of a fire. It is.

  Moreover, according to the said Example, a display score can be changed, without changing the setting etc. by the side of a display machine, and, thereby, the consistency of the display score of the whole system can be taken.

  Further, according to the above embodiment, since it is not necessary to provide the display device with a memory for storing the room number data, which is the data indicating the number of the room where the fire detector that has issued the fire is installed, The configuration is simple.

In the above embodiment, the room number display point selected by the fire receiver is sent to the display device, and the display device is set to the sent display point. The display unit displays the room number sent from the fire receiver as it is without sending the display point from the display unit to the display unit, that is, without setting the display point on the display unit side, and the displayed room The number of numbers may be the number of display points.
