Description

[Technical field]

[0001] The present invention relates to a fire alarm system using an intercom provided in each room of a collective housing unit such as an apartment building. [Background technology]

[0002] Conventionally, intercoms are installed in each room of a collective housing complex such as an apartment building, and under normal circumstances, they function to notify the presence of a visitor by voice and video and to unlock the collective entrance. On the other hand, there are also intercoms that are connected to fire detectors and the like that detect fires, and in the event of a fire, the intercom outputs an audio alarm accompanied by the room number of the room where the fire has occurred (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2000-20850 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the fire alarm system shown in Patent Document 1, when an alarm sound with the room number of the room where the fire occurred is output to a neighboring room in the same security zone in an apartment building, the following problems occur if the alarm sound is a false alarm. If the alarm sound is a false alarm, the resident of the room where the fire occurred may worry about causing great inconvenience to the residents of other units, or may have a bad relationship with the neighbors. In addition, outputting an alarm sound with the room number of the room added is not appropriate from the viewpoint of protecting personal information.

[0005] The present invention has been made in consideration of the above-mentioned situation, and aims to provide a fire alarm system that can quickly and easily identify the location of a fire while protecting personal information in the event of a fire in an apartment building. [Means for solving the problem]

[0006] The fire alarm system of the present invention comprises a fire alarm installed in each dwelling unit for detecting fires, an intercom master unit installed in each dwelling unit and equipped with a display unit for indicating a fire in the event of a fire, and a fire receiver connected to the fire alarm and the intercom master unit via a signal line and installed in a management room, wherein when a fire occurs in a dwelling unit, the fire receiver can identify the dwelling unit in which a fire has occurred based on a signal output from the fire alarm or the intercom master unit.In this fire alarm system for an apartment building composed of multiple dwelling units, the dwelling unit in which the fire has occurred and the multiple dwelling units surrounding it are set as a single fire area, and a determination means is provided for determining the fire area from the dwelling unit in which the fire has occurred, and in the event of a fire, fire area information is output from the fire receiver to the multiple dwelling units, and the intercom master unit displays the fire area information on the display unit. Effect of the Invention

[0007] According to the present invention, the dwelling unit where the fire occurred and the surrounding dwelling units are set as one fire area, a determination means is provided for determining the fire area from the dwelling unit where the fire occurred, and in the event of a fire, fire area information is output from the fire receiver to the multiple dwelling units, and the intercom master unit displays the fire area information on the display unit. Thus, according to the fire alarm system of the present invention, the fire area information displayed by the intercom master unit does not specify personal information of the dwelling unit where the fire occurred, but displays the fire area to which the dwelling unit belongs. Therefore, when a fire occurs in an apartment building, the location of the fire can be quickly and easily notified to the user while protecting personal information.

The transmitter 10_4 is connected to a terminating resistor TE_4, and the automatic fire alarm a_4_1 is connected to the fire receiver 1.

[0013] When a fire is detected, each of the automatic fire alarms a_1_1 to a_4_4 outputs a fire alarm signal including dwelling unit information indicating the dwelling unit where the fire occurred to the fire receiver 1. The dwelling unit information can be specified by the fire receiver 1 using the unique address of each automatic fire alarm, the room number of the dwelling unit where each automatic fire alarm is installed, location information, etc. Transmitters 10_1 to 10_4 are provided in the common areas of each floor (places other than dwelling units r_1_1 to r_4_4), and manually output fire alarm signals. The fire alarm signals output from the transmitters 10_1 to 10_4 include location information of the transmitters 10_1 to 10_4, respectively.

[0014] Further, intercom master units I_1_1 to I_4_4 are provided in the dwelling units r_1_1 to r_4_4, respectively. The intercom master units I_1_1 to I_4_4 are each connected to the fire control panel 1 via a signal line.

[0015] Each of the intercom master units I_1_1-I_4_4 has a display unit and performs processing such as displaying the overall map output from the fire receiving device 1. The overall map refers to an overall map displaying the fire areas of the dwelling units r_1_1-r_4_4 in the apartment building 101 as shown in FIG.

[0016] The fire receiver 1 is provided, for example, in a manager's room of an apartment building 101. The fire receiver 1 includes a storage unit that stores an overall map of a plurality of dwelling units r_1_1 to r_4_4 in the apartment building 101 and fire area information in which the plurality of dwelling units r_1_1 to r_4_4 are grouped as fire areas. The fire receiver 1 receives fire alarm signals output from the automatic fire alarms a_1_1 to a_4_4, and determines a group including a dwelling unit in which a fire has occurred, which is indicated by the dwelling unit information included in the received fire alarm signal, based on the fire area information stored in the storage unit. Then, the fire receiver 1 outputs an overall map in which the dwelling units in the determined group are displayed differently from the other dwelling units.

[0017] FIG. 2 is a diagram showing a hardware configuration of the fire receiver 1 in the fire alarm system 100 according to the first embodiment of the present invention.

[0018] As shown in FIG. 2, the fire receiver 1 has a CPU 12, a memory 13, an input unit 14, a communication unit 15, and a storage device 16, all of which are connected to a bus 11.

[0019] The CPU 12 cooperates with a fire area display program 21 according to the embodiment stored in the storage device 16 to perform fire area display processing on the fire receiver 1 side according to the embodiment, and also controls the entire fire receiver 1.

[0020] The memory 13 is used as a work area required when executing the fire area display program 21. The input unit 14 is a keyboard or the like for inputting data into the database 22 stored in the storage device 16.

[0021] The communication unit 15 controls communication with the outside of the fire control panel 1. Specifically, the communication unit 15 is connected to the automatic fire alarms a_1_1 to a_4_4, the intercom master units I_1_1 to I_4_4, and the transmitters 10_1 to 10_4 by electric wires to perform communication.

[0022] The storage device 16, which is a storage unit, has a fire area display program 21 and a database 22. The fire area display program 21 is a program that performs the fire area display processing according to the first embodiment on the fire receiver 1 side.

[0023] The database 22 stores an overall map m of the multiple dwelling units r_1_1 to r_4_4 in the apartment building 101, and fire area information in which the multiple dwelling units r_1_1 to r_4_4 are grouped as fire areas.

[0024] FIG. 3 is a diagram showing an overall map m of an apartment house 101 in which the fire alarm system 100 according to the first embodiment of the present invention is installed. In the overall map m, the dwelling units r_1_1 to r_4_4 are shown as rooms 101 to 404, respectively. The overall map m can include not only the dwelling units r_1_1 to r_4_4 but also common areas such as a corridor, an entrance, and a parking lot. FIG. 3 shows the overall map m including the entrance. The fire area is divided into groups of multiple neighboring dwelling units (for example, 4 to 6 units adjacent vertically and / or horizontally). In other words, the area of ​​the dwelling unit where the fire occurred and the surrounding dwelling units grouped together is treated as the fire area. In FIG. 3, Room 101 (Dwelling Unit r_1_1), Room 102 (Dwelling Unit r_1_2), Room 201 (Dwelling Unit r_2_1), and Room 202 (Dwelling Unit r_2_2) are considered to be the first group. Room 301 (Dwelling unit r_3_1), Room 302 (Dwelling unit r_3_2), Room 401 (Dwelling unit r_4_), and Room 402 (Dwelling unit r_4_2) are group 2. Room 103 (Dwelling unit r_1_3), Room 104 (Dwelling unit r_1_4), Room 203 (Dwelling unit r_2_3), and Room 204 (Dwelling unit r_2_4) are group 3. Room 303 (Dwelling unit r_3_3), Room 304 (Dwelling unit r_3_4), Room 403 (Dwelling unit r_4_3), and Room 404 (Dwelling unit r_4_4) are group 4.

[0025] The database 22 has fire area information. The fire area information has first to fourth groups which are fire areas, and the first to fourth groups are associated with the following dwelling unit r. Fire area information = 1st group + 2nd group + 3rd group + 4th group 1st group = {dwelling unit r_1_1, dwelling unit r_1_2, dwelling unit r_2_1, dwelling unit r_2_2} Second group = {Dwelling unit r_3_1, Dwelling unit r_3_2, Dwelling unit r_4_1, Dwelling unit r_4_2} 3rd group = {dwelling unit r_1_3, dwelling unit r_1_4, dwelling unit r_2_3, dwelling unit r_2_4} 4th group = {dwelling unit r_3_3, dwelling unit r_3_4, dwelling unit r_4_3, dwelling unit r_4_4} The entrance may also be included in the fifth group of fire area information.

[0026] FIG. 4 is a diagram showing a hardware configuration of the intercom master unit I in the fire alarm system 100 according to the first embodiment of the present invention.

[0027] As shown in FIG. 4, the intercom master unit I has a CPU 32, a memory 33, a display unit 34, an audio output unit 35, a communication unit 36, and a storage device 37, all of which are connected to a bus 31.

[0028] The CPU 32 cooperates with the parent unit intercom side fire area display program 41 of the embodiment stored in the memory device 37 to perform fire area display processing on the intercom parent unit I side of the embodiment, and also controls the entire intercom parent unit I.

[0029] The memory 33 is used as a work area required when executing the master intercom side fire area display program 41. The display unit 34 is, for example, a liquid crystal display, and displays the fire area transmitted from the fire receiver 1. The audio output unit 35 outputs the fire information transmitted from the fire receiver 1 by audio.

[0030] The communication unit 36 ​​includes a communication circuit for communicating with the fire control panel 1 .

[0031] The storage device 37, which is a storage unit, has a master intercom side fire area display program 41 and a database 42. The master intercom side fire area display program 41 is a program that performs the master intercom side processing of the fire area display processing according to the first embodiment.

[0032] Next, a description will be given of the operation of the fire alarm system 100 according to the first embodiment of the present invention. Fig. 5 is a flowchart for explaining the operation of the fire alarm system 100 according to the first embodiment of the present invention.

[0033] In the first embodiment, a case will be described in which a fire breaks out in room 302 (dwelling unit r_3_2) and is detected by an automatic fire alarm a_3_2.

[0034] When the automatic fire alarm a_3_2 detects a fire, it outputs a fire alarm signal including dwelling unit information (dwelling unit r_3_2) indicating the dwelling unit where the fire occurred (step S1).

[0035] When the fire receiver 1 receives a fire alarm signal (YES in step S2), it determines the fire area (second group) including the dwelling unit in which the fire indicated by the dwelling unit information (dwelling unit r_3_2) included in the fire alarm signal has occurred, based on the fire area information stored in the database 22 (step S3). Note that the processing from step S3 onwards is carried out when it is determined that a fire has occurred. When it is determined that a fire has occurred, for example, a fire alarm signal is received from the transmitter 10 on the floor of the dwelling unit r where the fire has occurred. When the fire receiver 1 does not receive a fire alarm signal (NO in step S2), it waits to receive a fire alarm signal.

[0036] Next, the fire receiving device 1 outputs an overall map m_1, which displays the dwelling unit r in the determined fire area so as to be different from the other dwelling units r, to the intercom master units I_1_1-I_4_4 of the dwelling units r_1_1-r_4_4 (step S4).

[0037] The intercom master units I_1_1 to I_4_4 of the respective dwelling units r_1_1 to r_4_4 display the overall map m output from the fire receiving device 1 on the display unit 34, and output audio information notifying the occurrence of a fire from the audio output unit 35 (step S5).

[0038] FIG. 6 is a diagram showing an overall map m_1 in which a fire area is displayed on the display unit 34 of the intercom master unit I in the fire alarm system 100 according to the first embodiment of the present invention.

[0039] As shown in FIG. 6, the dwelling units r_3_1, r_3_2, r_4_1, and r_4_2 of the second group, which includes room 302 (dwelling unit r_3_2) where the fire occurred, are displayed on the overall map m_1 as the fire area.

[0040] The display of the fire area on the overall map m_1 is, for example, a display in which the colors of Room 301 (dwelling unit r_3_1), Room 302 (dwelling unit r_3_2), Room 401 (dwelling unit r_4_1), and Room 402 (dwelling unit r_4_2) of the second group are different from the colors of the other dwelling units, but the display method of the fire area is not important as long as it can be distinguished from others. Also, in the intercom master unit I of the dwelling units other than the fire area, if the fire area is nearby, such as above, below, left, or right, the display of the fire area on the display unit 34 may be flashed or an audio alarm may be issued to emphasize or notify the occurrence of a fire in a nearby dwelling unit.

[0041] Furthermore, the fire receiver 1 can display the intercom master unit I installed in the dwelling unit where the fire has occurred differently from other dwelling units. For example, rather than displaying the fire area on the overall map, it is desirable to display only the dwelling unit in question differently from other dwelling units, or to display the occurrence of a fire on the entire display unit 34, so that the dwelling unit where the fire has occurred can be notified of the fact that there is a fire quickly and clearly.

[0042] In the first embodiment, the case where the fire receiver 1 transmits the overall map m_1 to the intercom master units I_1_1-I_4_4 of all the dwelling units r_1_1-r_4_4 has been described, but the map may be transmitted only to the intercom master units I installed in the dwelling units r belonging to the group including the dwelling unit r where the fire report was issued, or to the intercom master units I installed in the adjacent dwelling units r, such as above, below, left and right of the fire area, in conjunction with the timing of the activation of each automatic fire alarm a. This makes it possible to minimize the range of the fire notification, thereby preventing a situation in which many residents of dwelling units are unnecessarily involved in the event of a non-fire, and preventing trouble between the resident of the dwelling unit where the fire occurred and other residents.

[0043] According to the fire alarm system 100 of the first embodiment, when a fire breaks out in the apartment house 101, the fire receiver 1 creates an overall map m_1 displayed so that it can be recognized as a fire area including the dwelling unit r where the fire occurred, not just the dwelling unit r where the fire occurred, and outputs the map to the intercom master units I_1_1 to I_4_4. Therefore, according to the fire alarm system 100 of the first embodiment, the intercom master units I of the dwelling units r other than the dwelling unit r where the fire occurred display the location of the fire as a fire area on the overall map m_1, so that it is possible to grasp the approximate location of the fire without specifying the dwelling unit where the fire occurred, and therefore it is possible to evacuate while avoiding the fire area, and the location of the fire can be quickly and easily confirmed for the residents of the dwelling unit r where the fire occurred, while protecting the personal information of the residents of the dwelling unit r where the fire occurred.

[0044] Embodiment 2 In the first embodiment, a case has been described in which the fire receiver 1 outputs the overall map m_1 to the intercom master units I_1_1 to I_4_4. In the second embodiment, the fire receiver 1 outputs dwelling unit information, and the intercom master unit I creates and displays the overall map m_1.

[0045] In the second embodiment, the database 22 of the fire receiver 1 does not store the overall map m and the fire area, and the database 42 of the intercom master unit I stores the overall map m and the fire area. Specifically, the database 42 of the intercom master unit I stores the overall map m of the multiple dwelling units r_1_1 to r_4_4 in the apartment building 101, and fire area information in which the multiple dwelling units r_1_1 to r_4_4 are grouped as fire areas.

[0046] FIG. 7 is a flowchart for explaining the operation of the fire alarm system 100 according to the second embodiment of the present invention.

[0047] In the second embodiment, as in the first embodiment, a case will be described in which a fire breaks out in room 302 (dwelling unit r_3_2) and is detected by an automatic fire alarm a_3_2.

[0048] When the automatic fire alarm a_3_2 detects a fire, it outputs a fire alarm signal including dwelling unit information (dwelling unit r_3_2) indicating the dwelling unit where the fire occurred (step S11).

[0049] When the fire receiver 1 receives a fire alarm signal (YES in step S12), it outputs the dwelling unit information included in the fire alarm signal (step S13). When the fire receiver 1 does not receive a fire alarm signal (NO in step S12), it waits for reception of a fire alarm signal.

[0050] Next, the fire receiver 1 outputs the dwelling unit information contained in the fire alarm signal (step S13).

[0051] The intercom master unit I of each residence r determines the fire area including the residence in which the fire has occurred, as indicated by the residence information output from the fire receiver 1, based on the fire area information stored in the database 42, which is a memory unit (step S14).

[0052] Next, the intercom master unit I of each dwelling unit r displays an overall map m_2 in which the dwelling units in the determined fire area are displayed differently from the other dwelling units (step S15).

[0053] According to the fire alarm system 100 of the second embodiment, when a fire breaks out in the apartment house 101, the intercom master units I_1_1 to I_4_4 create an overall map m_1 displayed so that it can be recognized as a fire area including the dwelling unit r where the fire occurred, not only the dwelling unit r where the fire occurred, and display the created overall map m_1. Therefore, according to the fire alarm system 100 of the second embodiment, as in the first embodiment, the intercom master units I of the dwelling units r other than the dwelling unit r where the fire occurred display the location of the fire as a fire area on the overall map m_1, so that it is possible to grasp the approximate location of the fire without specifying the dwelling unit where the fire occurred, and therefore it is possible to evacuate while avoiding the fire area, and the personal information of the residents of the dwelling unit r where the fire occurred can be protected, while the location of the fire can be quickly and easily confirmed for the residents of the other dwelling units r.

[0054] The embodiments are presented as examples and are not intended to limit the scope of the claims. The embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the embodiments. These embodiments and their modifications are included in the scope and spirit of the embodiments. [Explanation of symbols]
