Description

The present invention relates to a display device that displays a map on the front surface and displays an illumination from behind the map in accordance with the contents of an event such as a fire.

  Conventionally, in a monitoring facility such as a fire alarm system, an event occurs in which a display panel indicates area warning windows indicating the alert area in multiple rows and columns, and a fire signal is received by a fire detector. In such a case, the fire representative light is turned on to give an acoustic alarm, and the district indicator light of the district where the fire is detected blinks or lights up.

  On the other hand, in recent years, instead of the previous district indicator lamp, a map of the warning area is displayed on the display unit of the display device, and the light emission is displayed in a spot-like manner in each warning zone drawn on the map, for example, each room. When the display unit is placed on the back side and a fire signal is received, the light-emitting display unit of the area where the fire was detected is driven, and the location of the fire is displayed on the map with spot lighting, making the fire location easy Display devices that can be easily grasped have been put into practical use.

The light-emitting display unit used in this display device incorporates light-emitting elements such as LEDs, and a large number of light-emitting display units are temporarily attached to a transparent plate on the back side of the map with a double-sided adhesive sheet, and then A signal line is drawn from each of the light emitting display portions and connected to a drive circuit of a circuit board.

  However, in such a display device that displays the spot of fire on the map in a spot-like manner by driving the light-emitting display unit arranged on the back side, many signal lines are connected from the light-emitting display unit arranged on the back side of the device. The signal line is pulled out to the circuit board on which the drive circuit is mounted and the position of the light-emitting display unit can be freely changed according to the map change. For example, when blinking driving is performed, noise may be emitted from the signal line, which may affect the operation of a CPU or the like installed in the vicinity. Further, by changing the position of the light emitting display portion in accordance with the map change, stress is repeatedly applied to the connection portion of the circuit board of the signal line, which may adversely affect the electrical connection.

  In addition, since the light emitting display unit connected by the signal line is driven at a position away from the driving circuit, it is necessary to drive the LED with a large power so as to compensate for the loss due to the signal line. There is also the problem of increasing power.

  Furthermore, when changing the map, it is necessary to remove the fixing support plate and change the arrangement of the light emitting display part, and then to attach and fix the support plate after the change. Since the size corresponds to a large display window, it takes time to attach and detach the support plate, and there is a problem that the work associated with the change is complicated.

  Also, it is necessary to prepare separate LEDs and signal lines according to the number of map sections, and even when changing the layout, additional LEDs and signal lines must be prepared separately and connected to the circuit. It is.

It is an object of the present invention to provide a display device that suppresses the generation of electrical noise and can easily rearrange the display position associated with a map change.

  FIG. 1 is an explanatory view showing a disaster prevention receiving board using the display device of the present invention. In FIG. 1, the disaster prevention monitoring panel 10 has a display device 12 of the present invention disposed at the top of the panel and an operation display panel 14 disposed below it. On the display device 12, for example, a plane for each floor of the building in the warning area monitored by the disaster prevention monitoring panel 10 is drawn as a map, and a circle is displayed for each warning section partitioned by walls on each floor. A plurality of portions 12a are arranged.

  From the disaster prevention monitoring panel 10, a sensor line is drawn out to the warning area. When a fire is detected by the fire detector connected to the sensor line, a fire alarm is issued by the disaster prevention monitoring panel 10, and at the same time a fire is detected. The display section of the fire occurrence section in the map on the floor on the display device 12 that detects this is turned on or blinked.

  FIG. 2 is an explanatory view showing an embodiment of the display device according to the present invention, which is taken out and attached to the rear side of the front side of the disaster prevention monitoring panel 10 of FIG.

  In FIG. 2, the display device 12 of the present invention has a map display unit displaying a warning area map arranged in the front panel opening of the disaster prevention monitoring panel 10, and the map display unit has a display window 16 on the front side. A transparent acrylic plate or glass plate is used as 16. A rear cover member 20 is detachably provided behind the display window 16 with a map sheet member 18 interposed therebetween. As the back cover member 20, a transparent acrylic resin plate or the like is used.

  On the map sheet member 18 sandwiched between the display window 16 and the back cover member 20, as shown by the display device 12 in FIG. It is drawn by printing. As the map sheet member 18, paper or film that can be printed by a color printer or the like is used.

  A plurality of illumination display members 24 are arranged on the back surface of the back cover member 20. The illumination display member 24 is arranged at a position corresponding to each monitoring section of the map of the building of the warning area printed on the map sheet member 18.

  An optical fiber 26 is drawn out from the illumination display member 24 and connected to a light source unit 28 mounted on a circuit board 22 installed at another place in the panel. A drive circuit for the light source unit 28 is mounted on the circuit board 22. When a fire signal is received, the light source unit 28 in the corresponding monitoring section is driven to emit light, and light from the light source unit 28 that has been driven to emit light is emitted. The light is transmitted to the illumination display member 24 through the optical fiber 26, and the map sheet member 18 is backlit from the back surface through the back cover member 20 from the illumination display member 24, and a fire occurs on the map when viewed from the front side of the display window 16. A spot-like display indicating the location is performed.

  FIG. 3 is a cross-sectional explanatory view showing an illumination display member and a light source unit connected by an optical fiber in the embodiment of FIG. In FIG. 3, the illumination display member 24 is bonded and fixed to the back surface of the back cover member 20 disposed with the map sheet member 18 interposed therebetween with respect to the display window 16 using a transparent or translucent double-sided adhesive sheet 25. The

  The illumination display member 24 has an adapter 30, and the distal end of the optical fiber 26 from the light source unit 28 is inserted into the adapter 30, and the distal end of the optical fiber 26 is positioned at the bottom of the storage portion 30 a that opens in the front cylindrical shape. A scattering member 32 is incorporated in the storage portion 30 a of the adapter 30. The scattering member 32 receives and scatters the light from the optical fiber 26 and converts the spot light from the optical fiber 26 into a surface light source.

  A color filter 34 is disposed following the scattering member 32. The color filter 34 causes the light converted into the surface light source to be colored and emitted by the scattering member 32. The use of the color filter 34 is used when the light from the light source unit 28 is white light. When the light from the light source unit 28 is colored, the color filter 34 is unnecessary.

  Subsequent to the color filter 34, a mask member 36 is disposed. The mask member 36 has a cutout 36 a having an appropriate shape, for example, a circular cutout 36 a, at the center portion, and defines the projection shape of the illumination light output from the illumination display member 24.

  The scattering member 32, the color filter 34, and the mask member 36 incorporated in the opening hole of the adapter 30 are incorporated and fixed by a transparent cap member 38 attached from the opening side. The transparent cap member 38 is formed with a fitting projection 38 a on the inner edge of the opening, and is assembled and fixed by fitting the fitting projection 38 a into the fitting groove 30 a on the outer periphery of the adapter 30.

  On the other hand, the light source unit 28 provided on the circuit board 22 is disposed relative to the LED 40 which is a light emitting element mounted on the circuit board 22 with the tip of the optical fiber 26 inserted and fixed by the adapter 42.

  That is, the adapter 42 forms a flange 42a to be fixed to the circuit board 22, and is fixed to the circuit board 22 by adhesion of the flange 42a. A cylindrical portion 42 b is formed behind the adapter 42, and the tip of the optical fiber 26 is inserted into the cylindrical portion 42 b so as to be in contact with the LED 40.

  As the optical fiber 26 used in this embodiment, it is desirable to use a plastic optical fiber. A plastic optical fiber is an optical fiber that uses acrylic as a core material, and uses a fluororesin as a grad material covering the core material, and is characterized by being cheaper, more resistant to bending, and less likely to break than a quartz-based optical fiber.

  Unlike quartz optical fibers, it has a large aperture, fiber diameter of 1 mm, and core diameter of 0.98 mm. Even if there are some scratches, dirt, or optical axis misalignment on the fiber end face, it has sufficient efficiency. The light from the LED 40 can be transmitted to the illumination display member 24 so that the map sheet member 18 can be backlit.

  Moreover, as LED40 used for the light source unit 28, since the fire occurrence place on a map is shown by backlight illumination, red LED can be used. When the red LED is used, the color filter 34 provided on the illumination display member 24 is not necessary. Moreover, white LED can also be used as LED40. When a white LED is used, a color filter 34 is arranged on the illumination display member 24 and a necessary display color is set.

  FIG. 4 is an exploded view showing the illumination display device of FIG. In FIG. 4, the illumination display member 24 has an adapter 30 into which an optical fiber 26 is inserted and connected. The adapter 30 is formed with a fitting groove 30b on the outer periphery, and a cylindrical storage portion 30a is opened on the tip side. A scattering member 32 is incorporated in the accommodating portion 30a of the adapter 30, and the spot light from the optical fiber 26 is converted into a surface light source by scattering.

  Following the scattering member 32, a color filter 34 is disposed as necessary. Subsequently, the mask member 36 in which the circular cutout 36a is formed is incorporated. As the cutout 36a of the mask member 36, a projection shape by appropriate illumination can be set in addition to the circular shape.

  In the state where the scattering member 32, the color filter 34, and the mask member 36 are incorporated in the cylindrical storage portion 30a of the adapter 30, a transparent cap member 38 is finally fitted on the distal end side, and FIG. The fitting portion 38a shown in FIG. 5 can be fitted into the fitting groove 30b of the adapter 30 and fixed.

  Since the illumination display member 24 having the structure shown in FIG. 4 does not incorporate an LED serving as a light source, it can be reduced in size and weight, and the optical fiber 26 is also very thin and lightweight with a fiber diameter of 1 millimeter. Therefore, as shown in FIG. By simply using the double-sided pressure-sensitive adhesive sheet 25, the back cover member 20 can be securely fixed to the position corresponding to the warning area of the map sheet member 18 of the back cover member 20.

  When the map of the map sheet member 18 is changed, the illumination display member 24 is removed from the back cover member 20 as necessary, and the double-sided pressure-sensitive adhesive sheet 25 is also used to change the corresponding position on the map after the change. It can be easily moved and placed.

  Further, since the light from the light source unit 28 of the circuit board 22 is transmitted to the illumination display member 24 by the optical fiber 26, the signal line for driving the LED 40 as the light source is compared with the illumination display member using the conventional signal line. Therefore, problems such as noise due to signal line wiring can be completely eliminated. Further, since the LED 40 as the light source is mounted on the circuit board 22 on which the driving circuit is mounted, it is not necessary to increase the power in consideration of the loss due to the signal line, and the LED 40 can be driven to emit light with a small driving power.

  FIG. 5 is an explanatory view showing another embodiment of a display device according to the present invention using a connector type light source unit. 5, the illumination display member 24 arranged on the display window 16 side of the display device 12 of this embodiment is the same as that of the embodiment of FIG. 2, but a connector type as a light source unit installed on the circuit board 22 side. The light source unit 46 is used.

A plurality of LEDs 40 are incorporated in the connector base 48, and lead terminals are connected to the connector lead pins 52 taken out on the right side.

  A connector cover 50 is detachably attached to the connector base 48. The connector cover 50 is inserted and fixed so that the tip portions of the plurality of optical fibers 26 are positioned at positions facing the LEDs 40 incorporated in the connector base 48. ing.

  By using such a connector type light source unit 46, the light source unit with respect to the circuit board 22 and the optical fiber 26 can be assembled and arranged very easily.

  In particular, as shown in FIG. 5, when the illumination display member 24 is fixed to the rear cover member 20 disposed with the map sheet member 18 interposed between the display window 16 and the connector cover 50 from the circuit board 22 side. By removing the, the arrangement of the plurality of illumination display members with respect to the back cover member 20 can be easily performed on the display window 16 side without considering the wiring of the optical fiber 26 with respect to the circuit board 22. After the arrangement and fixing of the illumination display member 24 with respect to 20 is completed, the connector cover 50 is incorporated into the connector base 48 of the circuit board 22, so that the optical connection with the LED 40 as the light source using the optical fiber 26 by the plurality of illumination display members 24 is easily performed. Connection can be completed.

A hole 56 is formed.

  As shown in FIG. 9B, the mounting hole 56 has, for example, notches 60 formed at two opposite positions in the lateral direction. On the other hand, in the illumination display member 24, the optical fiber 26 is inserted and fixed by the adapter 30, and the bottomed cylindrical transparent cap member 38 in a state where the scattering member 32, the color filter 34 and the mask member 36 are incorporated in the housing portion 36 a of the adapter 30. Are inserted and fixed from the front, and retaining projections 58 are formed at two locations on the outer periphery of the transparent cap member 38.
