BEST MODE FOR CARRYING OUT THE INVENTION

[0012] Hereinafter, embodiments will be described with reference to the drawings. Note that each of the embodiments described below shows comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components, order of steps, etc. shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, the components not described in the independent claims indicating the most general concept are described as optional components.

[0013] Note that each figure is a schematic diagram and is not necessarily drawn precisely. Also, in each figure, the same reference numerals are given to substantially the same configurations, and redundant descriptions may be omitted or simplified.

[0014] (1) Embodiment 1 (1.1) Overview Hereinafter, the master unit 1 which is an embodiment of the receiver of the present disclosure, and the automatic fire alarm system 100 including the same will be described with reference to the drawings.

[0015] As shown in FIG. 1, the master unit 1 (receiver) of the present embodiment is electrically connected to a pair of electric wires 31 and 32 together with the slave unit 2 (sensor), and can communicate with the slave unit 2 by changing the current flowing through the pair of electric wires 31 and 32. As shown in FIG. 2, a plurality of communication lines L1 are connected to the master unit 1 with a pair of electric wires 31 and 32 as one communication line L1. Further, a plurality of slave units 2 are connected to each of the plurality of communication lines L1.

[0016] As shown in FIG. 1, the master unit 1 includes a receiving unit 14, a display unit 15, an acquisition unit 171, and a first modification unit 172.

[0017] The receiving unit 14 receives a signal transmitted from the slave unit 2 via the communication line L1. In particular, the receiving unit 14 receives a fire report which is a notification signal for notifying the occurrence of a fire from the slave unit 2.

[0018] The display unit 15 displays (outputs) fire information (display information, output information) indicating information related to a fire (disaster prevention) based on the fire report received by the receiving unit 14. The fire information is expressed by at least one of characters, numbers, and symbols, and is displayed on the display unit 15 by, for example, characters, numbers, symbols, or a combination thereof. The content of the fire information includes, for example, information indicating the communication line L1 to which the slave unit 2 that notified the fire report is connected, or information on the location where the slave unit 2 that notified the fire report is installed. The information indicating the communication line L1 is, for example, the line number assigned in advance to each communication line L1, or information on the location where each communication line L1 is wired. The information on the location where the slave unit 2 is installed is, for example, the name of the location registered in advance in association with each slave unit 2 (the name of the location where the slave unit 2 is installed, for example, the room number in an apartment house).

[0019] Note that the display unit 15 is an example of a user interface unit capable of outputting fire information related to a fire (disaster prevention) based on the notification signal received by the reception unit 14.

[0020] The acquisition unit 171 acquires user information regarding the user using the master unit 1 (more specifically, for example, the face of the user). In the present embodiment, the acquisition unit 171 is an imaging unit that captures an imaging image including the face of the user using the master unit 1. That is, in the present embodiment, the user information includes information obtained from the imaging image that captures the user.

[0021] The first change unit 172 changes the display mode of the display information displayed on the display unit 15 based on the user information acquired by the acquisition unit 171. In the present embodiment, the display mode is, for example, the type of language (Japanese, English, Chinese, etc.) used in the display information.

[0022] As described above, since the master unit 1 of the present embodiment includes the acquisition unit 171 and the first change unit 172, the display mode (output mode) of the display information (output information) displayed (output) on the display unit 15 can be automatically changed according to the user. Thereby, for example, the language used in the display information displayed on the display unit 15 can be automatically changed to the language corresponding to the user.

[0023] (1.2) Overall configuration Hereinafter, as shown in FIG. 2, the case where the automatic fire notification system 100 of the present embodiment is used in the apartment house A1 (for example, condominium) will be illustrated. Of course, the automatic fire notification system 100 of the present embodiment may be used not only in the apartment house A1 but also in various buildings such as, for example, a detached house, a commercial facility, a hospital, a hotel, and a multi-tenant building.

[0024] As shown in FIG. 2, the automatic fire alarm system 100 of this embodiment is provided with one master unit 1 and a plurality (here, 16) of slave units B1 to B16 for an apartment building A1. In this automatic fire alarm system 100, a plurality (here, 4) of communication lines L1 (L11 to L14) are connected to the master unit 1. Two or more (here, 4) slave units 2 are connected to each communication line L1. Specifically, slave units B1 to B4 are connected to communication line L11, slave units B5 to B8 are connected to communication line L12, slave units B9 to B12 are connected to communication line L13, and slave units B13 to B16 are connected to communication line L14. Also, at the end of each communication line L1 (the end opposite to the master unit 1), a pair of electric wires 31, 32 are electrically connected via a termination resistor C1. Therefore, the master unit 1 can detect a disconnection of the pair of electric wires 31, 32 by monitoring the current flowing between the pair of electric wires 31, 32. In the following description, when explaining without distinguishing each of the slave units B1 to B16, it will be explained as the "slave unit 2".

[0025] Here, each of the plurality of slave units 2 is either one of a first slave unit 21 and a second slave unit 22.

[0026] When the first slave unit 21 detects the occurrence of a fire, it short-circuits between the pair of electric wires 31, 32 to transmit a signal (hereinafter referred to as a "fire alarm") notifying the occurrence of the fire to the master unit 1. That is, the first slave unit 21 here is a contact-type fire detector used in a so-called P-type (Proprietary-type) automatic fire alarm system. When a fire alarm is transmitted from the first slave unit 21, the master unit 1 cannot know from which slave unit 2 (the first slave unit 21) the fire alarm is being transmitted. Therefore, in this case, the master unit 1 identifies the source of the alarm in units of the communication line L1.

[0027] When the second slave unit 22 detects the occurrence of a fire, it transmits a fire alarm to the master unit 1 via communication using a transmission signal transmitted through a pair of electric wires 31, 32. Also, after transmitting the alarm (after sending the fire alarm), when the second slave unit 22 receives from the master unit 1 a transmission signal including an address request for requesting the address (identifier) of the source of the fire alarm, it transmits the pre-assigned address to the master unit 1 using the transmission signal. That is, when a fire alarm is transmitted from the second slave unit 22, the master unit 1 can identify the source of the alarm in units of the slave unit 2 (the second slave unit 22) by communicating with the second slave unit 22 which is the source of the alarm.

[0028] The automatic fire alarm system 100 is basically configured such that a slave unit 2 which is a sensor (such as a heat sensor, a smoke sensor, or a flame sensor) detects the occurrence of a fire, and a notification of the occurrence of the fire (a fire alarm) is made from the slave unit 2 to the master unit 1 which is a receiver. However, the slave unit 2 is not limited to a sensor that detects the occurrence of a fire, and may include a transmitter or the like. The transmitter has a push button switch (not shown), and is a device that notifies the master unit 1 of the occurrence of a fire by manually operating (pushing) the push button switch when a person discovers a fire.

[0029] Note that the automatic fire alarm system 100 may have an interlocking function with other equipment such as a smoke control and exhaust equipment (not shown) and an emergency broadcast equipment (not shown). In this case, the automatic fire alarm system 100 can control the fire door of the smoke control and exhaust equipment or notify the occurrence of a fire by sound or voice using the emergency broadcast equipment when a fire occurs.

[0030] By the way, there are two types of systems in general automatic fire alarm systems: a P-type (Proprietary-type) system and an R-type (Record-type) system. In the P-type automatic fire alarm system, the slave unit notifies the master unit of the occurrence of a fire by electrically short-circuiting between a pair of electric wires. In the R-type automatic fire alarm system, the slave unit notifies the master unit of the occurrence of a fire via communication using a transmission signal transmitted through a transmission line.

[0031] The automatic fire alarm system 100 of this embodiment is based on the P type. In the automatic fire alarm system 100 of this embodiment, in the apartment building A1 where the P-type automatic fire alarm system was installed, it is assumed that the existing wiring (communication line L1) is used as it is, and the master unit 1 and a plurality of slave units 2 (the first slave unit 21 and the second slave unit 22) are replaced. Here, some of the slave units 2 may use the existing slave units as they are. Of course, the automatic fire alarm system 100 of this embodiment can also be adopted as a newly introduced automatic fire alarm system.

[0032] Hereinafter, the configurations of the master unit 1 and the slave units 2 will be described in detail. In the following, one first slave unit 21 and one second slave unit 22 out of the plurality of slave units 2 will be described, and the description of the remaining slave units 2 will be omitted. Also, in the following, one of the plurality of communication lines L1 will be focused on for explanation.

[0033] (1.3) Configuration of Slave Unit First, the configurations of the slave units 2 (the first slave unit 21 and the second slave unit 22) will be described with reference to FIG. 1. In FIG. 1, one first slave unit 21 and one second slave unit 22 each composed of sensors connected to one communication line L1 are shown, and the illustration of the other slave units 2 is omitted. Each slave unit 2 is installed in the rooms, stairways, corridors, etc. of the apartment building A1.

[0034] As shown in FIG. 1, the first slave unit 21 includes a (first) diode bridge 211, a (first) power supply unit 212, a (first) sensor 213, a thyristor 214, and a drive unit 215.

[0035] The diode bridge 211 has a pair of electric wires 31 and 32 electrically connected to its input terminal, and a power supply unit 212 and a thyristor 214 electrically connected to its output terminal. The power supply unit 212 generates power for the operation of the first slave unit 21 by being supplied with power from the pair of electric wires 31 and 32. The sensor 213 detects the occurrence of a fire by detecting, for example, changes in the concentration of smoke, changes in temperature, and changes in the concentration of gases such as carbon monoxide. The drive unit 215 shorts the pair of electric wires 31 and 32 by turning on the thyristor 214 in response to the output of the sensor 213.

[0036] With this configuration, when the first slave unit 21 detects the occurrence of a fire, it turns on the thyristor 214 to create a short - circuit state in which the pair of electric wires 31 and 32 are electrically short - circuited, thereby notifying the master unit 1 of the fire alarm.

[0037] As shown in FIG. 1, the second slave unit 22 includes a (second) diode bridge 221, a (second) power supply unit 222, a (second) sensor 223, a transmission unit 224, a reception unit 225, a control unit 226, and a storage unit 227.

[0038] The diode bridge 221 has a pair of electric wires 31 and 32 electrically connected to its input terminal, and the power supply unit 222, the transmission unit 224, and the reception unit 225 electrically connected to its output terminal. The power supply unit 222 generates power for the operation of the second slave unit 22 by being supplied with power from the pair of electric wires 31 and 32. The sensor 223 detects the occurrence of a fire by detecting, for example, changes in the concentration of smoke, changes in temperature, and changes in the concentration of gases such as carbon monoxide. The control unit 226 controls the transmission unit 224 and the reception unit 225 to transmit a fire alarm and a transmission signal from the transmission unit 224 to the master unit 1 or receive a transmission signal from the master unit 1 at the reception unit 225 in response to the output of the sensor 223.

[0039] The transmission unit 224 transmits a signal to the master unit 1 by changing the current flowing through the pair of electric wires 31 and 32. That is, the transmission unit 224 draws in and changes the current from the pair of electric wires 31 and 32 to transmit a current signal to the master unit 1.

[0040] The receiving unit 225 receives the transmission signal from the master unit 1 as a voltage signal (voltage change) on a pair of electric wires 31 and 32. That is, the current value of the current drawn by the master unit 1 from the pair of electric wires 31 and 32 corresponds to the magnitude of the voltage drop across the resistor 12. Therefore, the receiving unit 225 receives the signal represented by the current value of the current drawn by the master unit 1 as a voltage signal.

[0041] The storage unit 227 stores the address (identifier) pre-assigned to the second slave unit 22. Each of the plurality of second slave units 22 is assigned a unique address. Each address is associated with the installation location (for example, room number) of each of the plurality of second slave units 22 and is stored in the storage unit 20 of the master unit 1.

[0042] (1.4) Configuration of the master unit In this embodiment, the master unit 1 has a function as a P-type receiver that receives a fire occurrence notification (fire alarm) from the slave unit 2. The master unit 1 is installed, for example, in the management room of a building (Apartment Building A1).

[0043] As shown in FIG. 1, in addition to the receiving unit 14, the display unit 15 (user interface unit), and the acquisition unit 171, the master unit 1 includes an application unit 11, a resistor 12, a transmission unit 13, an operation unit 16, a control unit 17, a storage unit 20, an emergency power supply 18, and a communication interface (referred to as "communication I / F" in FIG. 1) 19.

[0044] The application unit 11 applies a predetermined voltage to the pair of electric wires 31 and 32 under the control of the control unit 17. Here, as an example, the voltage applied by the application unit 11 between the pair of electric wires 31 and 32 is 24V DC, but it is not intended to be limited to this value.

[0045] The resistor 12 is connected between the application unit 11 and at least one of the pair of electric wires 31 and 32. In the example of FIG. 1, the resistor 12 is inserted between one (high potential side) of the pair of electric wires 31 and 32, i.e., the electric wire 31, and the application unit 11. However, not limited to this example, the resistor 12 may be inserted between the other (low potential side) electric wire 32 and the application unit 11, or may be inserted between both of the pair of electric wires 31 and 32 and the application unit 11, respectively.

[0046] The resistor 12 has two functions: a first function of converting the current flowing through the resistor 12 into a potential difference (voltage) between both ends of the resistor 12 by voltage drop, and a second function of limiting the current flowing through the pair of electric wires 31 and 32 when the pair of electric wires 31 and 32 are short-circuited. In short, the resistor 12 has both the first function as a current-voltage conversion element and the second function as a current limiting element. Here, as an example, the resistance value of the resistor 12 is 470 Ω, but it is not intended to be limited to this value.

[0047] The transmission unit 13 is electrically connected between the resistor 12 and the pair of electric wires 31 and 32. The transmission unit 13 transmits a transmission signal to the second slave unit 22 by changing the current flowing in from the pair of electric wires 31 and 32. That is, the transmission unit 13 transmits a transmission signal to the second slave unit 22 by changing the current flowing through the pair of electric wires 31 and 32 by drawing in the current flowing from the application unit 11 to the resistor 12.

[0048] The reception unit 14 is electrically connected between the resistor 12 and the pair of electric wires 31 and 32. The reception unit 14 discriminates between a state in which the pair of electric wires 31 and 32 are short-circuited by the first slave unit 21 and a state in which they are not short-circuited. The reception unit 14 thereby receives a fire alarm transmitted by the first slave unit 21 short-circuiting between the pair of electric wires 31 and 32.

[0049] In addition, the receiving unit 14 receives the signal transmitted from the second slave unit 22 by drawing current from the pair of electric wires 31 and 32 as a voltage change between the pair of electric wires 31 and 32. That is, the current value of the current drawn by the second slave unit 22 from the pair of electric wires 31 and 32 corresponds to the magnitude of the voltage drop across the resistor 12. Therefore, the receiving unit 14 receives the voltage change (voltage signal) that occurs on the pair of electric wires 31 and 32 when the second slave unit 22 changes the current drawn from the pair of electric wires 31 and 32 as a transmission signal. Also, the receiving unit 14 receives the address transmitted by the second slave unit 22 as a response to the address request. Thereby, the master unit 1 can know which second slave unit 22 has notified the fire alarm.

[0050] The display unit 15 is provided, for example, on the front surface of the housing of the master unit 1. The display unit 15 performs various displays. As shown in FIG. 3, the display unit 15 includes a plurality of display lamps 151 and a liquid crystal display unit 152.

[0051] Each of the plurality of display lamps 151 includes, for example, an LED (Light Emitting Diode). Each of the plurality of display lamps 151 is controlled by the control unit 17 to be turned on, off, blink, etc. Some of the plurality of display lamps 151 (20 display lamps 151 at the left end in the example of FIG. 3) are respectively associated with the plurality of communication lines L1. Each of these display lamps 151 associated with the communication line L1 includes, for example, a red LED, and when turned on, it indicates that a fire alarm has been notified through the corresponding communication line L1, and when blinking, it indicates that a disconnection has occurred in the corresponding communication line L1. Also, some of the other plurality of display lamps 151 indicate the state of the master unit 1 respectively. These display lamps 151 include, for example, a transmitter lamp with a red LED, an AC power lamp with a green LED, a trouble lamp with a red LED, etc. The transmitter lamp blinks to indicate that the push button of the transmitter connected to any of the communication lines L1 has been pressed. The AC power lamp lights up to indicate that the power is turned on for the master unit 1. The trouble lamp blinks to indicate that an abnormality has occurred in the master unit 1 or any of the communication lines L1.

[0052] The liquid crystal display unit 152 displays various information under the control of the control unit 17. The liquid crystal display unit 152 displays information by at least one of characters, numbers, and symbols. In particular, the liquid crystal display unit 152 displays information indicating the content of the fire alarm received from the slave unit 2. Information indicating, for example, that a fire has occurred, the floor where the fire has occurred, or the location where the fire has occurred is displayed on the liquid crystal display unit 152 as fire information (display information, output information). Also, information (including confirmation messages, etc.) for performing various settings of the automatic fire alarm system 100 is also displayed on the liquid crystal display unit 152.

[0053] The operation unit 16 accepts input operations for performing various settings of the automatic fire alarm system 100. The operation unit 16 includes a plurality of push buttons 161. The plurality of push buttons 161 include a selection switch button for switching the display content displayed on the liquid crystal display unit 152 and an execution switch button for executing the display content displayed on the liquid crystal display unit 152. The plurality of push buttons 161 further include an input switch button for causing the liquid crystal display unit 152 to display characters, numbers, symbols, etc.

[0054] The communication interface 19 is, here, a card slot into which a recording medium such as a memory card can be inserted. The communication interface 19 transmits the information stored in the inserted card slot to the control unit 17 in response to an input operation to the operation unit 16, for example. Note that the communication interface 19 may be a connector or the like to which a communication line from an external device is connected.

[0055] The backup power supply 18 includes a storage battery. Here, the master unit 1 uses a commercial power supply, a home power generation facility, etc. as the main power supply. The application unit 11 automatically switches the power supply source from the main power supply to the backup power supply 18 when the main power supply fails, and automatically switches from the backup power supply 18 to the main power supply when the main power supply is restored. By providing the backup power supply 18 in this way, it is possible to ensure the power supply for the operation of the automatic fire alarm system 100 even during a power outage.

[0056] The acquisition unit 171 acquires user information regarding the user using the master unit 1. The user information acquired by the acquisition unit 171 is output to a later-described first modification unit 172 of the control unit 17. In the present embodiment, the acquisition unit 171 is an imaging unit that captures an image including the face of the user using the master unit 1. The imaging unit is configured by, for example, a CCD image sensor or the like. The imaging unit captures a moving image in the present embodiment, but may capture a still image. One frame of the captured image of the moving image captured by the imaging unit is used as user information. The imaging unit is provided on the master unit 1 so as to capture a person at a predetermined position around the master unit 1 who is trying to view the display information displayed on the liquid crystal display unit 152 of the master unit 1. The imaging unit is provided at a predetermined location around the liquid crystal display unit 152 on the front surface of the housing of the master unit 1 (see FIG. 3).

[0057] The control unit 17 controls the transmission unit 13 and the reception unit 14 to cause the transmission unit 13 to transmit a signal or cause the reception unit 14 to receive a signal from the slave unit 2. Further, the control unit 17 controls the lighting and extinguishing of the display lamp 151 of the display unit 15 and controls the display content displayed on the liquid crystal display unit 152. The control unit 17 mainly includes, for example, a computer having a CPU (Central Processing Unit) and a memory, and realizes various functions by executing a program stored in the memory by the CPU. The program may be recorded in advance in the memory of the computer, may be provided by being recorded on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0058] When the receiving unit 14 receives a fire alarm via any of the communication lines L1, the control unit 17 lights up the display lamp 151 and displays fire information indicating information about the fire on the liquid crystal display unit 152 based on this fire alarm. In one example, the content of the fire information includes information indicating the communication line L1 connected to the slave unit 2 that notified the fire alarm. For example, when the control unit 17 receives a fire alarm from the first slave unit 21, it causes the liquid crystal display unit 152 to display information indicating the communication line L1 on which the fire alarm was received. In another example, the content of the fire information includes information about the location where the slave unit 2 that notified the fire alarm is installed. For example, when the control unit 17 receives a fire alarm from the second slave unit 22, based on the address transmitted from this second slave unit 22, it causes the liquid crystal display unit 152 to display information indicating the second slave unit 22 on which the fire alarm was received. The content of these fire information (the content displayed on the liquid crystal display unit 152) is stored in the storage unit 20. The control unit 17 reads information from the storage unit 20 based on which communication line L1 and / or slave unit 2 the fire alarm was transmitted from, and causes the liquid crystal display unit 152 to display the read information.

[0059] For example, when the communication line L11 is wired on the first floor of the apartment building A1 and the receiving unit 14 receives a fire alarm via the communication line L11, the control unit 17 causes the liquid crystal display unit 152 to display information indicating that a fire has occurred on the first floor. In this case, for example, a message such as "1F FIRE OCCURRED" is displayed on the liquid crystal display unit 152.

[0060] For example, when the slave unit B1 is the second slave unit 22 and is installed in Room 1021 of the apartment building A1, and the receiving unit 14 receives a fire alarm from the slave unit B1, the control unit 17 causes the liquid crystal display unit 152 to display information indicating that a fire has occurred in Room 1021. In this case, for example, a message such as "ROOM 1021 FIRE OCCURRED" is displayed on the liquid crystal display unit 152.

[0061] The control unit 17 of the present embodiment includes a first changing unit 172 that changes the display mode (for example, language) of the display information (for example, fire information) displayed on the liquid crystal display unit 152.

[0062] The first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the user information (in this embodiment, an imaging image including the user's face) acquired by the acquisition unit 171.

[0063] More specifically, the first change unit 172 first determines, using face recognition technology, whether a human face is reflected in the imaging image captured by the acquisition unit 171. When the first change unit 172 determines that a human face is reflected in the imaging image, it regards the imaging image (an image for one frame) as user information. Then, the first change unit 172 identifies the user using the host device 1 based on the user information acquired from the acquisition unit 171. More specifically, in this embodiment, the user information includes information obtained from an imaging image including the user's face. In the storage unit 20, imaging images of the user's face are stored (registered) in advance for each user as reference images. That is, the user using the host device 1 has registered in the storage unit 20 in advance a reference image obtained by imaging the user's face. The above reference image is stored in association with the user's identification information (for example, name). The first change unit 172 collates the imaging image acquired by the acquisition unit 171 (that is, the imaging image including the user's face) with a plurality of reference images registered in advance in the storage unit 20. More specifically, the first change unit 172 extracts, for example, the feature points of the face from the user information and the reference image, and authenticates the face (person) from the degree of coincidence of the feature points. Then, the first change unit 172 identifies a reference image of the same face as the face included in the imaging image acquired by the acquisition unit 171 from among the plurality of reference images. Thereby, the first change unit 172 identifies the user using the host device 1 based on the user information acquired by the acquisition unit 171.

[0064] The first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 to a candidate mode corresponding to the above-specified user from among a plurality of candidate modes (for example, Japanese, English, Chinese, etc.). In the present embodiment, the display mode refers to the type of language (Japanese, English, Chinese, etc.) used in the display information displayed on the liquid crystal display unit 152. That is, in the present embodiment, the display information displayed on the liquid crystal display unit 152 is stored in the storage unit 20 in a plurality of candidate modes (Japanese, English, Chinese, etc.). The users (for example, Mr. A, Mr. B, Mr. C, Mr. D) registered in the master unit 1 are associated with any one of the plurality of candidate modes (Japanese, English, Chinese, etc.). For example, Mr. A and Mr. D are associated with the Japanese display mode, Mr. B is associated with the English display mode, and Mr. C is associated with the Chinese display mode. The first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 to a candidate mode corresponding to the above-specified user from among the above plurality of candidate modes. Thereby, for example, when the user using the master unit 1 is Mr. A, the display information displayed on the liquid crystal display unit 152 is displayed in the Japanese display mode corresponding to Mr. A. Also, when the user using the master unit 1 is Mr. B, the display information displayed on the liquid crystal display unit 152 is displayed in the English display mode corresponding to Mr. B.

[0065] Note that when the first change unit 172 does not acquire user information or when the user cannot be identified although the user information has been acquired, the first change unit 172 displays the display information on the liquid crystal display unit 152 in the Japanese (that is, the default-set language) display mode.

[0066] In this way, the first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the user information, thereby automatically changing the display mode of the display information displayed on the liquid crystal display unit 152 to a display mode corresponding to the user according to the user.

[0067] Further, the first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the input operation of the operation unit 16. More specifically, when the display mode is specified by the input operation of the operation unit 16, the first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 to the display mode specified by the input operation of the operation unit 16.

[0068] In addition, when the automatic change and the manual change overlap with respect to the change of the display mode of the display information displayed on the liquid crystal display unit 152, the first change unit 172 preferentially executes the manual change. Thereby, even if the display information displayed on the liquid crystal display unit 152 is automatically changed to, for example, an English display mode, it can be manually changed to a display mode other than English by an input operation to the operation unit 16. Note that the automatic change means that the first change unit 172 automatically changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the user information. The manual change means that the first change unit 172 changes the display information displayed on the liquid crystal display unit 152 based on the input operation of the operation unit 16.

[0069] (1.5) Operation of the master unit 1 Next, the operation of the master unit 1 will be described with reference to FIG. 4. In the following description, the case where fire information is displayed as an example of the display information on the liquid crystal display unit 152 of the master unit 1 is exemplified.

[0070] When a fire breaks out, the receiving unit 14 of the master unit 1 receives a fire report from the detector 2 that has detected the occurrence of the fire (S1). When the receiving unit 14 of the master unit 1 receives the fire report, the control unit 17 of the master unit 1 displays the fire information on the liquid crystal display unit 152 in the default display mode (for example, Japanese) (S2). Then, the first changing unit 172 of the master unit 1 determines whether the acquisition unit 171 has acquired user information (S3). As a result of this determination, if the first changing unit 172 determines that the acquisition unit 171 has not acquired user information, the process returns to step 2. Then, the process continues from step S2. On the other hand, as a result of the determination in step S3, if the first changing unit 172 determines that the acquisition unit 171 has acquired user information, the first changing unit 172 identifies the user who is using the master unit 1 (that is, the user looking at the liquid crystal display unit 152) based on the user information acquired by the acquisition unit 171 (S4). As a result of this identification, if the first changing unit 172 cannot identify the user based on the user information, the process returns to step S2. Then, the process continues from step S2.

[0071] On the other hand, as a result of the process in step S4, when the control unit 17 identifies the user who is using the master unit 1 based on the user information, the control unit 17 selects a candidate mode (for example, English) corresponding to the identified user from among a plurality of candidate modes (for example, a plurality of languages such as Japanese, English, Chinese, etc.). Then, the control unit 17 changes the fire information displayed on the liquid crystal display unit 152 to the selected candidate mode (S5). Thereby, the language (Japanese) used in the fire information displayed on the liquid crystal display unit 152 is changed to the language (for example, English) corresponding to the user who is looking at the fire information.

[0072] Then, the first change unit 172 determines whether the display mode has been specified by an input operation on the operation unit 16 (S6). As a result of this determination, if the first change unit 172 determines that the display mode has not been specified by an input operation on the operation unit 16, the process returns to step S3, and the process continues from step S3. On the other hand, as a result of the determination in step S6, if the first change unit 172 determines that the display mode has been specified by an input operation on the operation unit 16, the display mode (e.g., English) of the fire information displayed on the liquid crystal display unit 152 is changed to the display mode (e.g., Chinese) specified by the input operation on the operation unit 16 (S7). Thereby, it is possible to change to a display mode (e.g., Chinese) different from the display mode (e.g., English) automatically changed in step S5 by the input operation on the operation unit 16. Then, the process returns to step S3, and the process continues from step S3.

[0073] (1.6) Main effects The master unit 1 (receiver) according to the present embodiment is a receiver that receives a signal related to a fire (disaster prevention). The master unit 1 includes a display unit 15 (user interface unit), an acquisition unit 171, and a first change unit 172. The display unit 15 can display (output) fire information (information related to disaster prevention) based on the received signal. The acquisition unit 171 acquires user information regarding the user using the master unit 1. The first change unit 172 changes the display mode (output mode) of the display information (output information) displayed on the display unit 15 based on the user information acquired by the acquisition unit 171. Thereby, the display mode of the display information displayed on the display unit 15 can be automatically changed according to the user.

[0074] (1.7) Modification example (Modification example 1) In Embodiment 1, the acquisition unit 171 is an imaging unit that captures an image including the user's face, but it may also be a device that acquires the user's biometric information (fingerprint, voiceprint, vein, iris, etc.). For example, when the acquisition unit 171 acquires the user's fingerprint, it is a fingerprint reader that reads the user's fingerprint. Also, when the acquisition unit 171 acquires the user's voiceprint, it is a microphone that collects the user's voice. Further, when the acquisition unit 171 acquires the user's vein (e.g., finger vein), it is a vein reader that reads the user's vein. When the acquisition unit 171 acquires the user's iris (e.g., pupil iris), it is an iris reader that reads the user's iris.

[0075] (Modification Example 2) In Embodiment 1, the display mode is the type of language, but the display mode (output mode) may also be a mode regarding the restriction of display information (output information). That is, the first modification unit 172 may restrict the display information (output information) output from the liquid crystal display unit 152 (user interface unit) according to the user information. More specifically, the display information (output information) is composed of a plurality of information (element information), and each element information is assigned an importance level. Each user registered in the master device 1 has an importance level associated with them. The first modification unit 172 displays (outputs) on the liquid crystal display unit 152 the element information corresponding to the importance level set for the user among the display information (output information) based on the user information.

[0076] For example, when the liquid crystal display unit 152 is configured as a touch panel and the operation screen of the touch panel is displayed on the liquid crystal display unit 152 as display information, the content of the operation screen may be made different according to the importance level corresponding to the user. Thereby, the information accessible by the touch panel can be restricted according to the user.

[0077] Note that in this modification example, the case where the output information is display information is exemplified, but the output information is not limited to display information and may be information other than display information (e.g., voice information).

[0078] (Modification Example 3) In Embodiment 1, the user information may include the identification information of the user that the entry / exit management system for managing the entry and exit of the user has. As shown in FIG. 5, in the above-described entry / exit management system, the user Q1 registered in the entry / exit management system carries an ID tag 95 (information terminal) that records the identification information of the user Q1. In one or more locations P1 (such as a room or a passageway) that are the management targets of the entry / exit management system, a reading device 90 is installed. The reading device 90 is a device for reading the identification information of the user Q1 from the ID tag 95 carried by the user Q1 passing through the location P1 where the reading device 90 is installed. In the example of FIG. 5, a room is illustrated as an example of the location P1, and the reading device 90 is installed near the entrance / exit of the room, and the master unit 1 is installed on the inner wall of the room.

[0079] When the user Q1 passes through each location P1, the user Q1 causes the identification information of his / her own ID tag 95 to be read by the reading device 90 installed at that location P1. The entry / exit management system includes a server that stores the identification information read by each reading device 90. The above-described server is communicably connected to each reading device 90. The entry / exit management system manages the identification information stored in the server. Thereby, it is possible for the entry / exit management system to manage the actions of the user Q1 (such as when and where the user was). The above-described reading device 90 is an example of an identification information acquisition unit that acquires the identification information of the user Q1.

[0080] As shown in FIG. 5, the master unit 1 of this modification is installed at a predetermined location P1 and is communicably connected to the reading device 90 installed at the predetermined location P1. In this modification, when the reading device 90 at the location P1 where the master unit 1 is installed reads the identification information of the user Q1 from the ID tag 95 carried by the user Q1, the reading device 90 transmits the read identification information to the master unit 1. When the acquisition unit 171 of the master unit 1 acquires the identification information of the user Q1 from the reading device 90, the first modification unit 172 of the master unit 1 regards the identification information of the user acquired by the acquisition unit 171 as user information. That is, in this modification, the user information includes information obtained from the identification information of the user.

[0081] Then, based on the acquired identification information, the first modification unit 172 changes the display mode (e.g., language) of the display information displayed on the liquid crystal display unit 152 to the display mode corresponding to the user Q1. Thereby, for example, when the user Q1 enters the place P1 where the master unit 1 is installed, the reading device 90 reads the user's identification information from his / her ID tag 95. And when the user Q1 goes to the location of the master unit 1, the display information displayed on the liquid crystal display unit 152 of the master unit 1 is automatically changed to the display mode corresponding to the user Q1. Note that the dotted line in FIG. 5 shows an example of the movement path along which the user Q1 moves through the reading device 90 and the master unit 1 in sequence.

[0082] (2) Embodiment 2 (2.1) Overview In this embodiment, the first modification unit 174 is different from that in Embodiment 1. Hereinafter, the description will focus on the differences from Embodiment 1. The same components as those in Embodiment 1 are denoted by the same reference numerals and the description thereof will be omitted as appropriate.

[0083] The first modification unit 174 of this embodiment changes the display mode of the display information displayed on the display unit 15. In this embodiment, the display mode is, for example, the type of language (Japanese, English, Chinese, etc.) used in the display information.

[0084] Thus, since the master unit 3 of this embodiment includes the first modification unit 174, the display mode (output mode) of the display information (output information) displayed (output) on the display unit 15 can be automatically changed according to the user. Thereby, for example, the language used in the display information displayed on the display unit 15 can be changed.

[0085] (2.2) Configuration of the Master Unit 3 As shown in FIG. 6, the master unit 3 includes an application unit 11, a resistor 12, a transmission unit 13, a reception unit 14, a display unit 15 (user interface unit), an operation unit 16, a control unit 17, a storage unit 20, a backup power supply 18, and a communication interface (referred to as "communication I / F" in FIG. 1) 19.

[0086] In addition, the control unit 17 of the present embodiment includes a first change unit 174 that changes the display mode (e.g., language) of the display information (e.g., fire information) displayed on the display unit 15.

[0087] The first change unit 174 changes the display mode of the display information displayed on the display unit 15 based on the input operation of the operation unit 16. More specifically, when the display mode is specified by the input operation of the operation unit 16, the first change unit 174 changes the display mode of the display information displayed on the display unit 15 to the display mode specified by the input operation of the operation unit 16.

[0088] In the present embodiment, the display mode is the type of language (Japanese, English, Chinese, etc.) used in the display information displayed on the display unit 15. That is, in the present embodiment, the display information displayed on the display unit 15 is stored in the storage unit 20 in a plurality of candidate modes (Japanese, English, Chinese, etc.). The user of the master unit 3 selects any one of the plurality of candidate modes (Japanese, English, Chinese, etc.) and changes the display mode of the display information displayed on the display unit 15. Thereby, it is possible to change to a display mode corresponding to the user of the master unit 3.

[0089] (2.3) Operation of the master unit 3 Next, the operation of the master unit 3 will be described with reference to FIG. 7. In the following description, the case where fire information is displayed as an example of display information on the display unit 15 of the master unit 3 is illustrated.

[0090] When a fire occurs, the receiving unit 14 of the master unit 3 receives a fire report from the sensor 2 that has detected the occurrence of the fire (S10). When the receiving unit 14 receives the fire report, the control unit 17 of the master unit 3 displays the fire information on the display unit 15 in the default display mode (e.g., Japanese) (S11).

[0091] Then, the first modification unit 174 determines whether the display mode has been specified by an input operation on the operation unit 16 (S12). As a result of this determination, if the first modification unit 174 determines that the display mode has not been specified by the input operation on the operation unit 16, the process returns to step S12, and the process continues from step S12. On the other hand, as a result of the determination in step S12, if the first modification unit 174 determines that the display mode has been specified by the input operation on the operation unit 16, the display mode of the fire information displayed on the display unit 15 (for example, Japanese) is changed to the display mode specified by the input operation on the operation unit 16 (for example, Chinese) (S13). Then, the process returns to step S12, and the process continues from step S12.

[0092] (2.4) Main effects The master unit 3 according to the present embodiment is a receiver that receives a signal related to a fire. The master unit 3 includes a display unit 15 and a first modification unit 174. The display unit 15 can display fire information based on the received signal. The first modification unit 174 changes the display mode of the display information displayed on the display unit 15. Thereby, the display mode of the display information displayed on the display unit 15 can be changed. For example, even if there are a plurality of users who use the master unit 3 and foreigners are included among them, the master unit can be used.

[0093] (3) Embodiment 3 (3.1) Overview In the present embodiment, the master unit 4 is different from the first and second embodiments in that it includes a second modification unit 175. Hereinafter, the description will focus on the differences from the first and second embodiments, and the same components as those in the first and second embodiments will be denoted by the same reference numerals, and the description will be omitted as appropriate.

[0094] As shown in FIG. 8, the master unit 4 includes a second modification unit 175. The second modification unit 175 further changes the display mode changed by the first modification unit 174 to a default display mode when a predetermined condition is satisfied.

[0095] Since the master device 4 of the present embodiment includes the second change unit 175, after the display mode (output mode) of the display information (output information) displayed (output) on the display unit 15 is changed by the first change unit 174, when a predetermined condition is satisfied, it can be further changed to a default display mode.

[0096] Accordingly, for example, even if the language used in the display information displayed on the display unit 15 by the constructor (user) of the master device 4 during construction is changed to English, it can be further changed to the default language (for example, Japanese) during operation, preventing the user from forgetting to change it back. Therefore, for example, even when the constructor who performs construction and the administrator who performs management mainly use different languages, the master device 4 that can be used by both parties can be provided.

[0097] (3.2) Configuration of the master device 4 As shown in FIG. 8, the master device 4 includes an application unit 11, a resistor 12, a transmission unit 13, a reception unit 14, a display unit 15 (user interface unit), an operation unit 16, a control unit 17, a storage unit 20, a backup power source 18, and a communication interface (referred to as "communication I / F" in FIG. 8) 19, which are the components of the master device 1 of the first embodiment.

[0098] The control unit 17 of the present embodiment includes, in addition to the first change unit 174, a second change unit that further changes the display mode changed by the first change unit 174 to a default display mode when a predetermined condition is satisfied.

[0099] The second change unit 175 changes from the display mode changed by the first change unit 174 to a default display mode when a predetermined condition is satisfied. In the present embodiment, the display mode is the type of language (such as Japanese, English, Chinese, etc.) used in the display information displayed on the display unit 15, and a plurality of candidate modes (such as Japanese, English, Chinese, etc.) are stored in the storage unit 20. Here, the default display mode is a display language arbitrarily selected from a plurality of candidate languages, and it is preferable to select a language that can be understood by a user who frequently uses the management room of the building (Apartment House A1) where the master device 4 is installed.

[0100] After the first change unit 174 changes the display mode, the second change unit 175 changes the display mode from the display mode changed by the first change unit 174 to a default display mode in response to the passage of a certain period or more of time without operating the operation unit 16. That is, the "predetermined condition" described above refers to the passage of a certain period or more of time without operating the operation unit 16 after the first change unit 174 changes the display mode.

[0101] With such a configuration, when the master unit 4 has not been operated for a certain period or more, the display mode can be automatically changed to the default display mode. Specifically, for example, by setting the default display mode of the master unit 4 to Japanese display, even when the language used in the display information displayed on the display unit 15 by the constructor of the master unit 4 is changed to English during construction, it will be automatically changed to the default Japanese display during operation after a certain period of time has elapsed since construction.

[0102] Note that not limited to the above configuration, the second change unit 175 may change the display mode from the display mode changed by the first change unit 174 to the default display mode in response to the power being turned off after the first change unit 174 changes the display mode. Here, "the power is turned off" includes the case where the user turns off the power of the master unit 4 and the case where the power supply to the master unit 4 from the main power supply such as commercial power or in-house power generation equipment is cut off due to a power outage in the facility.

[0103] With such a configuration, when the power of the master unit 4 is turned off, the display mode can be automatically changed to the default display mode.

[0104] Furthermore, the second change unit 175 may change to the default display mode in response to the master unit 4 receiving a signal related to disaster prevention or crime prevention from the slave unit 2 after the first change unit 174 changes the display mode.

[0105] With such a configuration, in an emergency when an event related to crime prevention or disaster prevention occurs, the default display mode can be surely used.

[0106] As described above, the second change unit 175 can prevent forgetting to switch back the language by changing to the default display mode when a predetermined condition is satisfied from the display mode changed by the first change unit 174. Therefore, for example, even when the installer and the administrator who manages the installation mainly use different languages, the master unit 4 that can be used by both can be provided.

[0107] (3.3) Operation of the master unit 4 Next, the operation of the master unit 4 will be described with reference to FIG. 9. In the following description, a case where setting information during construction is displayed on the display unit 15 of the master unit 4 as an example of display information will be exemplified.

[0108] When the installer is a foreigner, the installer designates a language that he / she can understand by operating the input unit of the operation unit 16 of the master unit 4 when installing the automatic fire alarm system 100 including the master unit 4 (S20). The first change unit 174 of the master unit 4 displays the setting information, which is the information necessary for construction, in the display mode (for example, English) designated based on the input operation (S21).

[0109] Then, the second change unit 175 determines whether or not a predetermined condition is satisfied (S22). Here, the "predetermined condition" includes, as described above, that the time during which the operation unit 16 is not operated has elapsed for a certain period or more, that the power supply of the master unit 4 has been turned off, and that the master unit 4 has received a signal related to disaster prevention or crime prevention from the slave unit 2.

[0110] As a result of this determination, if the second change unit 175 determines that the predetermined condition is not satisfied, the process returns to step S21, and the process continues from step S21. On the other hand, as a result of the determination in step S22, if the second change unit 175 determines that the predetermined condition is satisfied, the display mode (for example, English) of the setting information changed by the first change unit 174 is changed to the default display mode (for example, Japanese) (S23). Then, the process returns to step S20, and the process continues from step S20.

[0111] (3.4) Main effects The master unit 4 according to this embodiment is a receiver that receives signals related to fires. The master unit 1 includes a display unit 15, a first changing unit 174, and a second changing unit 175. The second changing unit 175 further changes the display mode of the display information displayed on the display unit 15 changed by the first changing unit to a default display mode. Thereby, it is possible to prevent forgetting to change back after changing the display mode of the display information displayed on the display unit 15. Therefore, for example, even when the constructor who performs construction and the administrator who performs management mainly use different languages, it is possible to provide the master unit 4 that can be used by both parties.

[0112] (4) Variation The above embodiment is only one of various embodiments of the present disclosure. The above embodiment can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. Further, functions similar to the control unit 17 of the master units 1, 3, and 4 may be embodied by a control method, a computer program, or a non-transitory recording medium recording the computer program.

[0113] A control method according to one aspect is a control method for the master units 1, 3, and 4 including a display unit 15 capable of receiving signals related to disaster prevention or crime prevention and outputting information related to disaster prevention or crime prevention based on the received signals. It includes acquiring user information about the user using the master units 1, 3, and 4, and changing the display mode of the display information displayed on the display unit 15 based on the user information.

[0114] Further, a program according to one aspect is a program that causes a computer system to execute the above control method.

[0115] (Variation 1) In Embodiments 1 to 3, the display mode is the type of language used in the display information. However, the display mode may be the type of color of the characters used in the display information (black, red, blue, etc.), or the type of thickness or size of the characters.

[0116] In this modification example, in the case of Embodiment 1, the display information displayed on the display unit 15 is automatically changed in terms of the color, thickness, or size of the characters according to the user. Also, in the case of Embodiments 2 and 3, the display information displayed on the display unit 15 is automatically changed in terms of the color, thickness, or size of the characters according to the input operation of the user.

[0117] (Modification Example 2) In Embodiments 1 to 3, the user interface unit is the display unit 15 that displays display information (e.g., fire information), but it may also be an audio output unit that outputs output information (e.g., fire information) as audio. In the case of Embodiment 1, the first change unit 172 changes the output mode of the output information output from the audio output unit based on the user information acquired by the acquisition unit 171. In the case of Embodiments 2 and 3, the first change unit 174 changes the output mode of the output information output from the audio output unit based on the input operation of the user. The above output mode is the type of language used in the output information (e.g., Japanese, English, Chinese, etc.).

[0118] (Modification Example 3) In this modification example, as shown in FIG. 10, it is possible to display the same display information (output information) on the display unit 62 (second user interface unit) of the external terminal 60 carried by the user of the master unit 1 as the display information (output information) displayed on the display unit 15 (first user interface unit) of the master unit 1. That is, the user of the master unit 1 can view the same display information as the display information displayed on the display unit 15 of the master unit 1 on the display unit 62 of the user's external terminal 60.

[0119] Although not shown in the figure, it goes without saying that similar modification examples are also applicable to Embodiment 2 and Embodiment 3. That is, the same display information (output information) as the display information (output information) displayed on the display unit 15 (first user interface unit) of the master units 3 and 4 may be displayed on the display unit 62 (second user interface unit) of the external terminal 60 carried by the users of the master units 3 and 4.

[0120] More specifically, the external terminal 60 includes an information acquisition unit 61 and a display unit 62. The information acquisition unit 61 is a device that acquires predetermined information. The information acquisition unit 61 is, for example, a QR code reader that reads a QR code (registered trademark) as the predetermined information. The display unit 62 is a dot matrix type display unit capable of displaying various types of information. The master devices 1, 3, and 4 of this modified example further include an information output unit 173 that outputs the above-mentioned predetermined information in the master devices 1, 3, and 4 of the above-described embodiment. The information output unit 173 includes, for example, a display unit capable of displaying a QR code.

[0121] In the case of Embodiment 1 in this modified example, the information output unit 173 generates change information by changing the display mode of the same display information as the display information displayed on the display unit 15 based on the user information acquired by the acquisition unit 171. That is, the change information is information obtained by changing the display mode of the display information displayed on the display unit 15 to a display mode corresponding to the user. Then, the information output unit 173 outputs the generated change information as predetermined information.

[0122] In this modified example, when the user uses the master device 1 (for example, views the display information displayed on the display unit 15), the acquisition unit 171 of the master device 1 acquires user information regarding the user using the master device 1. Then, the information output unit 173 of the master device 1 generates the above-described change information from the user information acquired by the acquisition unit 171 and the display information displayed on the display unit 15. Then, the information output unit 173 outputs the generated change information as predetermined information. Then, the user acquires the above-mentioned predetermined information output from the information output unit 173 of the master device 1 by the information acquisition unit 61 of the external terminal 60, generates change information from the acquired predetermined information, and displays it on the display unit 62 of the external terminal 60. That is, the information output unit 173 of the master device 1 outputs the predetermined information to be read by the information acquisition unit 61 of the external terminal 60, thereby causing the display unit 62 of the external terminal 60 to display the above-mentioned change information.

[0123] Also, in the case of Embodiments 2 and 3, the information output unit 173 generates change information by changing the display mode of the same display information as the display information displayed on the display unit 15 based on the input operation of the user. That is, the change information is information obtained by changing the display mode of the display information displayed on the display unit 15 to a display mode corresponding to the input operation of the user. Then, the information output unit 173 outputs the generated change information as predetermined information.

[0124] In this modification example, when the user operates the operation unit 16 of the master units 3 and 4, the information output unit 173 of the master units 3 and 4 generates the above-described change information from the display information displayed on the display unit 15 based on the input operation of the user. Then, the information output unit 173 outputs the generated change information as predetermined information. Then, the user acquires the above-described predetermined information output from the information output unit 173 of the master units 3 and 4 by the information acquisition unit 61 of the external terminal 60, generates change information from the acquired predetermined information, and displays it on the display unit 62 of the external terminal 60. That is, the information output unit 173 of the master units 3 and 4 outputs predetermined information to be read by the information acquisition unit 61 of the external terminal 60, thereby displaying the above-described change information on the display unit 62 of the external terminal 60.

[0125] Thereby, the users of the master units 1, 3, and 4 can view the same display information as the display information displayed on the display unit 15 of the master units 1, 3, and 4 in a display mode corresponding to the user on the display unit 62 of the external terminal 60 of the user.

[0126] (Modification Example 4) In the above Modification Example 3, the above-described change information is directly transmitted and received between the master unit 1 and the external terminal 60. However, as shown in FIG. 11, the above-described change information may be transmitted and received between the master unit 1 and the external terminal 60 via an external server 70.

[0127] Although not shown in the figure, it goes without saying that similar modification examples are also applicable to Embodiment 2 and Embodiment 3. That is, the above-described change information is directly transmitted and received between the master units 3 and 4 and the external terminal 60.

[0128] In this case, the master units 1, 3, 4 and the external terminal 60 are each connected in a wired or wireless manner so as to be capable of communicating with an external server 70 via a communication network (e.g., a public switched telephone network, etc.). For example, the communication I / F 19 of the master unit 1 functions as a communication unit for communicating with the server 70. The external terminal 60 includes a communication unit 63 for communicating with the server 70. In the server 70, for each master unit 1, various display information and various display modes that the master unit 1 has are stored. The above-mentioned various display information is stored in association with identification information for identifying each other. The above-mentioned various display modes are stored in association with identification information for identifying each other. The above-mentioned various display information and various display modes are, for example, transmitted from the master units 1, 3, 4 to the server 70 and stored in the server 70.

[0129] In the case of Embodiment 1, the master unit 1 outputs information including first to fourth information as the above-mentioned predetermined information. The first information is identification information for identifying the master unit 1. The second information is identification information for identifying the display information displayed on the display unit 15 of the master unit 1. The third information is identification information for identifying a display mode corresponding to the user. The fourth information is information for identifying the location (address) of the server 70.

[0130] When the information acquisition unit 61 of the external terminal 60 acquires the above-mentioned predetermined information from the information output unit 173 of the master unit 1, based on the acquired predetermined information (i.e., the first to fourth information), the information specified by the first to third information of the above-mentioned predetermined information is acquired from the server 70 and displayed on the display unit 62 of the external terminal 60. As a result, it is possible to display, on the display unit 62 of the external terminal 60 carried by the user of the master unit 1, the same display information as that displayed on the display unit 15 of the master unit 1, which is changed to a display mode corresponding to the user. Thereby, the user of the master unit 1 can view the same display information as that displayed on the display unit 15 of the master unit 1 on the display unit 62 of the user's external terminal 60 in a display mode corresponding to the user.

[0131] Also, in the case of Embodiments 2 and 3, the master devices 3 and 4 output information including the first, second, and fourth information as the above-described predetermined information. When the information acquisition unit 61 of the external terminal 60 acquires the above-described predetermined information from the information output unit 173 of the master devices 3 and 4, based on the acquired predetermined information (that is, the first, second, and fourth information), the information specified by the first and second information of the above-described predetermined information is acquired from the server 70 and displayed on the display unit 62 of the external terminal 60. As a result, it is possible to display the same display information as the display information displayed on the display unit 15 of the master devices 3 and 4 on the display unit 62 of the external terminal 60 carried by the users of the master devices 3 and 4. Thereby, the users of the master devices 3 and 4 can view the same display information as the display information displayed on the display unit 15 of the master devices 3 and 4 in a display mode corresponding to the users on the display unit 62 of the users' external terminal 60.

[0132] (Modification Example 5) In Embodiments 1 to 3, the communication I / F 19 may be a communication unit that communicates with an external device using a wired or wireless communication network (for example, a public line network, etc.). In this case, the first change units 172 and 174 operate based on a signal from an external device received via the communication I / F 19. More specifically, the first change units 172 and 174 change the display mode of the display information displayed on the display unit 15 to the display mode specified by the signal received from the external device based on the signal received from the external device. Thereby, the first change units 172 and 174 of the master devices 1, 3, and 4 can be controlled by an external signal.

[0133] (Modification Example 6) In Embodiments 1 to 3, it is applied to an automatic fire alarm system that receives a signal related to a disaster (disaster prevention), but it may also be applied to an automatic crime prevention alarm system that receives a signal related to crime prevention.

[0134] (Other Modification Examples) In the automatic fire alarm system 100 according to the present disclosure, the control units 17 of the master units 1, 3, and 4 include a computer system. The computer system mainly consists of a processor and a memory as hardware. By the processor executing the program recorded in the memory of the computer system, the function as the control unit 17 of the master unit 1 in the present disclosure is realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, or may be provided by being recorded on a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). Here, integrated circuits such as the IC or LSI are called differently depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Further, for an FPGA (Field-Programmable Gate Array) that is programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit section inside the LSI, it can also be adopted as a processor. The plurality of electronic circuits may be integrated on one chip, or may be provided distributed on a plurality of chips. The plurality of chips may be integrated in one device, or may be provided distributed on a plurality of devices. The computer system mentioned here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0135] Also, the fact that a plurality of functions in the control units 17 of the master devices 1, 3, and 4 are aggregated in one housing is not an essential configuration of the control unit 17. That is, the components of the control unit 17 may be provided distributed in a plurality of housings. Further, at least some functions of the control unit 17 may be realized by a cloud (cloud computing) or the like.

[0136] In addition, the automatic fire alarm system 100 of the above-described embodiment is exemplified as being applied to a P-type automatic fire alarm system, but it may also be applied to an R-type automatic fire alarm system.
