Description

Technical Field

[0001] The present invention relates to a receiver used in a disaster prevention monitoring system (including a fire notification system) such as a fire receiver that receives signals from a fire detector, a transmitter, etc. and alarms a fire, and particularly relates to a technique effective for use in an information display unit in a P-type receiver.

Background Art

[0002] Conventionally, for fire receivers that receive signals from fire detectors, transmitters equipped with push buttons, etc. and alarm the occurrence of a fire, there are R-type fire receivers and P-type fire receivers. Among these, in the P-type fire receiver, a display window (area display window) is provided for each警戒区域, and the name of the警戒区域 is described in the area display window and a display lamp is provided. And when it is determined that one of the plurality of sensors installed in any警戒区域 has detected a fire, the display lamp of the area display window is lit to notify the occurrence of a fire in that area, and the警戒区域 where the fire has occurred can be specified by the name displayed in the area display window. On the other hand, the name of the警戒区域 may often be changed particularly during the progress of construction work or when tenants are replaced, etc., and each time it was necessary to change the name of the警戒区域 displayed in each area display window.

[0003] Generally, for the name of the警戒区域 in a receiver used for disaster prevention monitoring, a piece of paper or a sheet with characters written on it is used, and when changing the name of the警戒区域, it is done by replacing the piece of paper or sheet with characters written on it, and that replacement work was quite troublesome. Therefore, conventionally, in order to facilitate or correctly perform the replacement work when changing the name of the警戒区域, inventions such as those described in Patent Documents 1 to 3 have been proposed.

Prior Art Documents

Patent Documents

[0004]

Patent Document 1

[0005] The inventions described in Patent Documents 1 and 2 involve inserting or attaching display boards or display sheets, prepared for each district display window, into the display frame. As a result, the replacement process when changing the name of a restricted area is not sufficiently improved, and the sheet needs to be cut to a predetermined size after the name of the restricted area is printed on it. Therefore, there is a problem that changing the name of a restricted area is time-consuming, laborious, and costly. In addition, there is a risk that display boards or display sheets bearing the name of a restricted area may be attached to the display frame of the wrong district display window.

[0006] On the other hand, the invention described in Patent Document 3 involves dividing a rectangular window sheet into multiple equal sections along its length to accommodate multiple security zones, allowing the names of each zone to be written on it. Furthermore, locking pieces are formed at both ends along the length (upper and lower ends) to engage with locking grooves provided in the frame of the display panel's base. Additionally, a central locking piece is formed in the center of the window sheet to engage with a central locking groove provided in the frame of the base. As a result, it is necessary to cut or fold the paper into a predetermined shape after printing the names of the security zones, which is time-consuming and laborious. Moreover, these window sheets must be manufactured by a manufacturer as dedicated parts and kept on hand, making the management of spare window sheets troublesome for both the manufacturer and the customer using them.

[0007] This invention was made against the background described above, and its objective is to provide a receiver for a disaster prevention monitoring system that allows for easy and quick changes to the names of monitoring areas displayed in the area display window. Another object of the present invention is to provide a receiver for a disaster prevention monitoring system that simplifies the process of changing the names of monitoring areas displayed in the district display window and allows for name changes at low cost. [Means for solving the problem]

[0008] To solve the above problems, the invention described in this application is: A receiver for a disaster prevention monitoring system comprising: a main function unit capable of detecting the occurrence of an event in response to a signal from a terminal device installed within a monitored area; a housing having an opening on the front side and housing the main function unit; a display unit having multiple area display windows capable of displaying information about the warning area where an event detected by the main function unit has occurred; and a front door having the display unit and disposed to cover the opening of the housing, The aforementioned display unit is An electronic substrate having through holes formed in portions corresponding to the multiple area display windows, and light-emitting elements mounted in portions corresponding to indicator lights provided near the multiple area display windows, The system is configured to include a display sheet disposed on the back of the aforementioned electronic circuit board, on which information about the restricted area is displayed in each of the multiple area display windows.

[0009] With the above configuration, the names of multiple monitoring areas can be changed simultaneously simply by placing a display sheet with information on the new monitoring area on the back of the electronic circuit board. This makes it easy and quick to change the names of the monitoring areas displayed in the area display window.

[0010] Here, preferably, the display sheet shall be a sheet having one of the dimensions specified by the standards for paper sizes defined by the International Organization for Standardization or the Japanese Industrial Standards. With this configuration, since the paper bearing the new monitoring area name only needs to be inserted into the designated area without cutting or folding, the process of changing the monitoring area name displayed in the area display window is simplified, and the name change can be performed at a low cost. In addition, there is no need for the manufacturer to produce and manage special paper. Furthermore, the display unit or the like may be configured to include a mechanism for holding the display sheet.

[0011] Furthermore, preferably, the display unit is An opaque window panel is disposed on the front of the electronic circuit board, with through-holes formed in the area display window that displays information about the restricted area and in the area corresponding to the indicator lights provided near the area display window, The electronic circuit board comprises a retaining panel disposed on the back of the electronic circuit board with a predetermined gap, The lower end of the retaining panel is bent forward to form a retaining mechanism for the display sheet, and an insertion opening for the display sheet is formed between the upper end of the electronic circuit board and the upper end of the retaining panel. The display sheet, inserted through the insertion opening, is disposed between the electronic circuit board and the retaining panel, and the height of the electronic circuit board and / or the retaining panel is set to be smaller than the vertical length of the display sheet disposed between the electronic circuit board and the retaining panel.

[0012] With the above configuration, the upper edge of the display sheet placed on the back of the electronic circuit board protrudes above the upper edges of the electronic circuit board and the retaining panel, making it easy to replace the display sheet.

[0013] Furthermore, preferably, the display unit is provided with a single transparent protective panel that is positioned on the front of the window panel and covers the entire window panel. With this configuration, compared to conventional receivers in which a protective panel is provided for each of the multiple district display windows, the number of parts can be reduced, and the effort required to attach the protective panel to the display unit can be simplified, thereby reducing costs.

[0014] Furthermore, preferably, the retaining panel is formed in a box shape with an open front, and the protective panel, the window panel, and the electronic circuit board are housed in recesses of the retaining panel. The electronic substrate is disposed with a predetermined gap between it and the rear wall of the holding panel, and a slit is formed on the upper wall of the holding panel corresponding to the gap so that the display sheet can be inserted.

[0015] According to the above configuration, a display unit having a plurality of area display windows capable of displaying information on a warning area where an event such as a fire has occurred can be configured as a unit, making it easy to handle. In addition, since a slit through which the display sheet can be inserted is provided on the upper wall of the box-shaped holding panel, the display sheet can be replaced without removing the holding panel from the front door of the receiver, and the name of the monitoring area can be changed.

Effect of the Invention

[0016] According to the receiver for a disaster prevention monitoring system of the present invention, since the names of a plurality of monitoring areas displayed in the area display windows can be changed simultaneously, the operation of changing the names of the monitoring areas can be performed easily and in a short time. In addition, since it is only necessary to insert a sheet on which the name of the new monitoring area is written into a predetermined part without cutting or folding it, the operation of changing the name of the monitoring area displayed in the area display window is simplified and the name change can be performed at low cost. Further, there is an effect that it is not necessary for the manufacturer to manufacture and manage dedicated paper.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, an example of the front door of a P-type fire receiver to which the present invention is applied is shown. The fire receiver 10 in FIG. 1 is installed in a building's disaster prevention center or central control room (or superintendent's room), and includes a main control board and a housing 11 with a built-in power source (battery) that receives fire signals from sensors and transmitters (terminal devices) installed in the building, and a front door 12 mounted so as to cover the front opening of the housing 11. The front door 12 is attached to the housing 11 so as to be openable and closable by hinges provided on the side. The main control board has a function of sounding a district sound device when receiving a fire signal from a sensor or transmitter to notify the occurrence of a fire acoustically, and notifying the occurrence of a fire (event) by means of a display such as a lamp provided on the front door 12 of the fire receiver 10.

[0019] As shown in FIG. 1, on the front door 12 of the fire receiver 10, there is provided a display panel 20 having a district display window for displaying fire alarms and the lines on which the alarms were issued, and an operation unit 30 having lamps for displaying the operating state of the fire receiver such as the input of signals from the transmitter, and push buttons for inputting commands to stop the district sound. In addition, on the front surface of the front door 12, in addition to the above, there may be provided a district display window for a smoke control and exhaust line for displaying the location where a fire occurred or the location where a smoke control and exhaust terminal or the like operated, a speaker for notifying the occurrence of a fire, an information display section for displaying information such as the results when various tests are carried out, and the like. Further, on the front surface or inside of the front door 12, there may be provided a fire test switch button for instructing the start of a fire test, a fire recovery button for instructing recovery from a fire test, and the like.

[0020] The display panel 20 has multiple sets of district display windows 20a, which display the name of the monitoring area (district), and indicator lights 20b, which light up to notify that a fire has occurred in the monitored area, arranged in two horizontal rows at a predetermined pitch. In conventional fire alarm receivers, a sheet with the district name written on it was provided for each district display window 20a. In the fire alarm receiver of the present invention, multiple district names are written on a single sheet (paper) and are configured to be visible in multiple district display windows.

[0021] Hereinafter, an embodiment of the structure of the display panel 20 in the fire alarm receiver of the present invention will be described using Figures 2 to 4. Of these, Figure 2 is a perspective view taken by cutting out the portion of the display panel 20 enclosed by the dotted line A in Figure 1 and disassembling it into front and rear sections. Figure 3 is a cross-sectional side view showing an example of a specific structure of the display panel 20, where (A) shows the state before the insertion of the district name display sheet 24, and (B) shows the state after the insertion of the district name display sheet 24.

[0022] As shown in Figure 2, the display panel 20 of this embodiment consists of, from front to back, a transparent protective panel 21 having the same size as the display panel 20, an opaque window panel 22 having through holes 22a and 22b in areas corresponding to the district display window 20a and indicator light 20b, an light-emitting element substrate 23 having a through hole 23a in the area corresponding to the district display window 20a and a light-emitting element 23b such as an LED mounted in the area corresponding to the indicator light 20b, a district name display sheet 24 on which the district name M is written (printed or inscribed), and a holding panel 25. The light-emitting element substrate 23 is made up of a printed circuit board and is electrically connected to the main control board installed inside the housing 11 by cables (not shown). Specifically, cables corresponding to at least two warning zones (two zone windows) displayed side by side on the zone name display sheet are routed from the printed circuit board to the right, left, or bottom of the zone name display sheet 24, bypassing the zone name display sheet, and connected to the main control board installed inside the housing 11 (see Figure 4).

[0023] Of the components 21-25 of the display panel 20 shown in Figure 2, all components except the district name display sheet 24 are joined together as a single unit. Specifically, for example, the protective panel 21, the window panel 22, the light-emitting element substrate 23, and the holding panel 25 are joined together by inserting common screws into screw insertion holes formed at the four corners of each and fixing them to the front door 12. When these components are joined, as shown in Figure 3(A), the light-emitting element substrate 23 and the holding panel 25 are joined with a slight gap, and the district name display sheet 24 is configured to be insertable from above (or from the side) into the gap between the light-emitting element substrate 23 and the holding panel 25, as shown in Figure 3(B). The direction in which the district name display sheet 24 is inserted does not have to be from above; it may also be from the side.

[0024] Furthermore, the upper end of the holding panel 25 is bent diagonally toward the rear to form a receiving opening, making it easier to insert the district name display paper 24 from above. In addition, the lower end of the holding panel 25 is bent horizontally toward the front, forming a mounting piece 25a that functions as a holding mechanism for the district name display paper 24, supporting it from below after it has been inserted through the receiving opening. The mounting piece 25a may be formed to extend below the protective panel 21. Similarly, bent pieces bent 90 degrees toward the front may be provided on both sides of the holding panel 25 to function as guide pieces for the district name display paper 24. In Figure 3, the area marked with the symbol M on the surface of the district name display sheet 24 represents the ink used to form the characters.

[0025] While not particularly limited, in this embodiment, the district name display sheet 24 is, for example, a sheet of paper of standard dimensions as defined in the ISO 216 or JIS P 0138 standards, and multiple district names to be displayed on the display panel 20 are written on a single sheet of paper by printing or printer printing. This simplifies the work required when changing district names. In addition, inexpensive general-purpose paper can be used, and the paper can be attached to the display panel 20 without any processing, that is, without cutting, folding, or creasing, thus reducing the cost required for changing names.

[0026] Furthermore, instead of arranging the district indicator window 20a and indicator light 20b in a horizontal direction as shown in Figure 4(Aa), they may be arranged in a vertical direction as shown in Figure 4(Ba). Also, the light-emitting element substrate 23 may be composed of multiple substrates 23A, 23B that are formed separately for each row, corresponding to the arrangement of the indicator lights, as shown in Figures 4(Ab) and 4(Bb). If the light-emitting element substrate is divided into multiple substrates and arranged at intervals, the through-hole 23a shown in Figure 2 becomes unnecessary.

[0027] Figure 5 shows an embodiment in which the display panel 20 is configured to be mounted on the inner surface of the front door 12. As shown in Figure 5, the display panel 20 in this embodiment is configured in the same way as the display panel in the embodiment described above, with a transparent protective panel 21, a window panel 22, a light-emitting element substrate 23, a district name display sheet 24, and a holding panel 25 arranged in order from the front. The front door 12 is provided with an opening 12A to allow the display panel 20 to be visible from the front. Furthermore, the retaining panel 25 is formed in a box shape with an open front side, having recesses for housing the protective panel 21, window panel 22, and light-emitting element substrate 23, and a slit 25b for inserting the district name display paper 24 is provided in the upper wall. Reference numeral 31 indicates the operating panel substrate, which is provided in correspondence with the operating panel 30 (Figure 1) of the front door 12.

[0028] In this embodiment, the protective panel 21, window panel 22, and light-emitting element substrate 23 are stacked and housed in a recess on the front side of the box-shaped retaining panel 25, thereby forming a unit (display unit). The retaining panel 25 has flange portions 25c at the front ends of both side walls, and multiple screw holes 25d are formed in these flange portions 25c. On the other hand, as shown in Figure 6, screws 26 are embedded in the edge of the opening 12A of the front door 12, and the retaining panel 25 is joined to the inner surface of the front door 12 by inserting these screws 26 through the screw holes 25d of the flange portions 25c, and the display unit 20' is fixed to the inner surface of the front door 12 by screwing nuts 27 onto the screws 26.

[0029] As described above, unitizing the display panel with the district display window makes it easier to handle. In addition, by providing a slit 25b for inserting the district name display paper 24 into the upper wall of the retaining panel 25 which serves as a storage case, the location for inserting and removing the district name display paper 24 is clearly defined, preventing incorrect insertion. Furthermore, by shaping the unit, or holding panel 25, so that its height is slightly shorter than the vertical length of the district name display paper 24 used, the upper edge of the paper 24 protrudes slightly when it is inserted into the holding panel 25, as shown in Figure 7. This allows the upper edge of the district name display paper 24 stored in the unit to be grasped, making it easy to replace the paper.

[0030] Furthermore, in the above embodiment, the front of the display panel or display unit is covered with a protective panel 21 made of a single transparent plate. However, the transparent plate may also be divided to the size of the district display window 20a and fitted into the through-hole 23a for each district display window to protect the district name display section. Furthermore, in the above embodiment, a slit 25b is provided in the upper wall of the retaining panel 25, but a slit may also be provided in the side wall or bottom wall. In addition, the upper wall of the retaining panel 25 may be omitted, and the upper end of the rear wall may be bent diagonally toward the rear to form a receiving opening, and a slit for inserting the district name display paper 24 may be provided in the upper wall of the front door 12.

[0031] As described above, in the fire alarm receiver of this embodiment, a display unit consisting of a display panel 20 is provided on the front door 12, which includes an electronic circuit board (23) with through-holes 23a formed in parts corresponding to multiple area display windows and light-emitting elements 23b mounted in parts corresponding to indicator lights provided near each area display window, and a single display sheet (24) disposed on the back of the electronic circuit board with information on the monitored area written on the parts corresponding to the multiple area display windows. Therefore, by simply placing a display sheet with new monitored area information (names of monitored areas) on the back of the electronic circuit board, the names of multiple monitored areas can be changed simultaneously. As a result, the work of changing the names of monitored areas displayed in the area display windows can be done easily and quickly.

[0032] Furthermore, as described above, the fire alarm receiver in this embodiment uses a display sheet (24) with information on the monitored area (name of the monitored area) that has dimensions specified by the International Organization for Standardization or the Japanese Industrial Standards. Therefore, it is only necessary to insert the sheet with the new monitored area name into the designated area without cutting or folding it. As a result, the process of changing the monitored area name displayed in the area display window is simplified, and the name change can be performed at a low cost.

[0033] Although the present inventor's invention has been described in detail above based on embodiments, the present invention is not limited to the above embodiments. For example, in the above embodiments, the protective panel 21, the window panel 22, and the light-emitting element substrate 23 are coupled or housed in the holding panel 25, but it is not necessary to couple or house all of the protective panel 21, the window panel 22, and the light-emitting element substrate 23. For example, the protective panel 21 and the window panel 22 may be installed on the front door 12, and the light-emitting element substrate 23 may be coupled or housed in the holding panel 25. Alternatively, the district name display sheet 24 may be housed in a transparent or translucent so-called clear file (clear folder) together with or instead of the protective panel 21.

[0034] Furthermore, in the above embodiment, the light-emitting element substrate 23 and the holding panel 25 are set to be the same height and smaller than the vertical length of the district name display paper 24. However, the height of either the light-emitting element substrate 23 or the holding panel 25 may be set to be smaller than the vertical length of the district name display paper 24. Furthermore, although the above description has used the application of the present invention to a Type P fire alarm receiver as an example, the present invention is not limited to a Type P fire alarm receiver and can be applied to a receiver that can be configured as a monitoring system and displays the district name of the protected area.
