Embodiments for Carrying Out the Invention

[0012] (1) Embodiment (1.1) Overview Hereinafter, a master unit 1 which is an embodiment of a receiver of the present disclosure, and an automatic fire alarm system 100 including the same will be described with reference to the drawings.

[0013] As shown in Fig. 1, the master unit 1 (receiver) of this 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 serving as one communication line L1. Further, a plurality of slave units 2 are connected to each of the plurality of communication lines L1.

[0014] As shown in Fig. 1, the master unit 1 includes a receiving unit 14, a display unit 15, and a control unit 17.

[0015] 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 alarm, which is a signal notifying the occurrence of a fire, from the slave unit 2.

[0016] The display unit 15 displays fire information (display information) indicating information about the fire based on the fire alarm 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, for example, by 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 alarm is connected, or information about the location where the slave unit 2 that notified the fire alarm 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 about the location where each communication line L1 is wired. The information about the location where the slave unit 2 is installed is, for example, the name of the location associated and registered in advance for each slave unit 2 (the name of the location where the slave unit 2 is installed, for example, the room number in an apartment building).

[0017] The control unit 17 controls the display information (e.g., fire information) displayed on the display unit 15. More specifically, the control unit 17 causes the display unit 15 to display information within a partial range of the display information, and changes (e.g., scrolls) the partial range within the display information. That is, the control unit 17 does not cause the display unit 15 to display the entire display information at once, but causes the display unit 15 to display only information within a partial range of the display information, and changes (e.g., scrolls) the partial range over the entire display information. Thereby, the control unit 17 causes the display unit 15 to display the display information in partial ranges one by one.

[0018] As described above, since the master unit 1 of the present embodiment includes the control unit 17, it is possible to cause the display unit 15 to display information within a partial range of the display information, and change (e.g., scroll) the partial range within the display information. Therefore, even when the number of characters in the display information increases, it is not necessary to reduce the size (display size) of the characters, numbers, and symbols (hereinafter also referred to as "characters, etc.") included in the display information, and the visibility of the display information displayed on the display unit 15 can be improved.

[0019] (1.2) Overall configuration Hereinafter, as shown in FIG. 2, a case where the automatic fire alarm system 100 of the present embodiment is used in an apartment house A1 (e.g., condominium) will be exemplified. Of course, the automatic fire alarm system 100 of the present embodiment may be used not only in the apartment house A1, but also in various buildings such as detached houses, commercial facilities, hospitals, hotels, and multi-tenant buildings.

[0020] 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 "slave unit 2".

[0021] Here, each of the plurality of slave units 2 is either one of a first slave unit 21 and a second slave unit 22.

[0022] 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 "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 by communication line L1 unit.

[0023] 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 and 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.

[0024] 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 fire occurrence (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 when a person manually operates (presses) the push button switch when discovering a fire.

[0025] Note that the automatic fire alarm system 100 may have an interlocking function for interlocking with other equipment such as a smoke control and exhaust equipment (not shown) or / 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 acoustically or by voice using the emergency broadcast equipment when a fire occurs.

[0026] By the way, there are two types of 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.

[0027] The automatic fire alarm system 100 of this embodiment is based on the P type. And in the apartment building A1 where the P-type automatic fire alarm system was installed in this embodiment, assume a case where 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.

[0028] 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 described focusing on one communication line L1.

[0029] (1.3) Configuration of the slave unit First, the configuration 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 consisting of a sensor 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 a room, a staircase, a corridor, etc. of the apartment building A1.

[0030] 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.

[0031] The diode bridge 211 has a pair of electric wires 31 and 32 electrically connected to its input terminal, and the power supply unit 212 and the 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 density 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.

[0032] 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 where the pair of electric wires 31 and 32 are electrically short - circuited, thereby notifying the master unit 1 of the fire alarm.

[0033] 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.

[0034] 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 density 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 by the reception unit 225 in response to the output of the sensor 223.

[0035] 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.

[0036] 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.

[0037] 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 170 of the master unit 1.

[0038] (1.4) Configuration of the master unit In the present 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 house A1).

[0039] As shown in FIG. 1, the master unit 1 includes, in addition to the receiving unit 14, the display unit 15, and the control unit 17, an application unit 11, a resistor 12, a transmission unit 13, an operation unit 16, a storage unit 170, an emergency power supply 18, and a communication interface (referred to as "communication I / F" in FIG. 1) 19.

[0040] 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.

[0041] 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 of the pair of electric wires 31 and 32 (the high-potential side 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) 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.

[0042] 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.

[0043] The transmission unit 13 is electrically connected between 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 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.

[0044] The reception unit 14 is electrically connected between the pair of electric wires 31 and 32. The reception unit 14 discriminates between a state where the pair of electric wires 31 and 32 are short-circuited by the first slave unit 21 and a state where 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.

[0045] Further, the receiving unit 14 receives the signal transmitted from the second slave unit 22 by drawing current from the pair of electric wires 31, 32 as a voltage change between the pair of electric wires 31, 32. That is, the current value of the current drawn by the second slave unit 22 from the pair of electric wires 31, 32 corresponds to the magnitude of the voltage drop across the resistor 12. Therefore, the receiving unit 14 receives the voltage change (voltage signal) generated on the pair of electric wires 31, 32 when the second slave unit 22 changes the current drawn from the pair of electric wires 31, 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.

[0046] The display unit 15 is provided, for example, on the front 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.

[0047] 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, indicates that a fire alarm has been notified through the corresponding communication line L1, and when blinking, 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 supply 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 supply 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.

[0048] The liquid crystal display unit 152 displays various information (display 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. As shown in FIG. 4, the liquid crystal display unit 152 of the present embodiment has a plurality of display areas 1520, and basically, by using one display area 1520 to display one character, number, or symbol, for example, a sentence including a plurality of characters is configured to be displayed. In particular, the liquid crystal display unit 152 displays information (display information) indicating the content of the fire alarm received from the slave unit 2. For example, information indicating that a fire has occurred, the floor where the fire has occurred, or the location where the fire has occurred is displayed as fire information on the liquid crystal display unit 152. Also, information (including confirmation messages, etc.) when performing various settings of the automatic fire alarm system 100 is also displayed on the liquid crystal display unit 152. The specific configuration of the liquid crystal display unit 152 will be described in the column of (1.5).

[0049] The operation unit 16 receives input operations when 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. Further, 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.

[0050] The communication interface 19 is, here, a card slot in which a recording medium such as a memory card can be mounted. The communication interface 19 transmits the information stored in the mounted 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.

[0051] The backup power source 18 is equipped with a storage battery. Here, the master unit 1 uses a commercial power source, a self-generated power facility, etc. as the main power source. The application unit 11 automatically switches the power supply source from the main power source to the backup power source 18 when the main power source fails, and automatically switches from the backup power source 18 to the main power source when the main power source is restored. By having the backup power source 18 in this way, it is possible to ensure the power source for the operation of the automatic fire alarm system 100 even during a power outage.

[0052] 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 consists of, for example, a computer having a CPU (Central Processing Unit) and a memory, and realizes various functions by executing the program stored in the memory with 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 an electric communication line such as the Internet.

[0053] 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 (communication line 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 the communication line information of the communication line L1 that received the fire alarm. In another example, the content of the fire information includes information (installation location 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 the second slave unit 22, it causes the liquid crystal display unit 152 to display the installation location information of the second slave unit 22 that received the fire alarm. Also, the content of the fire information may include a message in addition to the above communication line information or installation location information. The content of these fire information (the content displayed on the liquid crystal display unit 152) is stored in the storage unit 170. The control unit 17 reads information from the storage unit 170 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.

[0054] 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 fire information including information notifying the location of the fire (i.e., the wiring location of the communication line L11), which is the first floor. In this case, for example, fire information such as "1F Fire Occurrence" is displayed on the liquid crystal display unit 152.

[0055] 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 fire information including information notifying the location of the fire (i.e., the installation location of the slave unit 22), which is Room 1021. In this case, for example, fire information such as "Room 1021 Fire Occurrence" is displayed on the liquid crystal display unit 152.

[0056] When a fire alarm is notified from the communication line L1 or the slave unit 2, the control unit 17 of the present embodiment includes a setting unit 171 to set the content of the fire information displayed on the liquid crystal display unit 152 (the content of the fire information stored in the storage unit 170).

[0057] The setting unit 171 sets the display information (fire information) displayed on the liquid crystal display unit 152 when the fire alarm is received by the receiving unit 14. In particular, the setting unit 171 sets (changes or registers) the fire information displayed on the liquid crystal display unit 152 when the fire alarm is received by the receiving unit 14 in response to an input operation of the operator on the operation unit 16. In the master unit 1 of the present embodiment, the setting unit 171 can set the fire information for each communication line L1 and each slave unit 2 (each second slave unit 22).

[0058] For example, in the storage unit 170, as the fire information (hereinafter referred to as "first fire information") displayed on the liquid crystal display unit 152 when a fire alarm is received from the slave unit B1 of the communication line L11, a message such as "L001-01 FIRE OCCURRENCE" is stored by default. Here, "L001" in the message indicates the line number of the communication line L11, and "-01" indicates the address of the slave unit B1. The control unit 17 receives information regarding the content of the first fire information after the change via the operation unit 16. The content of the first fire information after the change is the content input by the user himself / herself through an operation on the operation unit 16 (an operation on the input switch button for displaying characters, numbers, symbols, etc.), and is, for example, a message such as "Fire occurred at No. 1021". Then, when the content of the first fire information after the change is determined by the operation on the operation unit 16, the setting unit 171 stores the content of the first fire information after the change in the storage unit 170 in association with the slave unit B1. As a result, when the receiving unit 14 receives a fire alarm from the slave unit B1 after the first fire information is changed, the control unit 17 causes the message "Fire occurred at No. 1021", which is the first fire information after the change, to be displayed on the liquid crystal display unit 152. Note that the content of the fire information corresponding to the other slave units B2 to B16 and the content of the fire information corresponding to the communication lines L11 to L14 can be changed in the same manner.

[0059] Furthermore, the setting unit 171 is configured such that the display mode of the display information (e.g., fire information) displayed on the liquid crystal display unit 152 can be set (changed or registered). Here, the display mode includes the size (display size) of characters, etc., color, or types such as fonts. In particular, the setting unit 171 is configured such that, as the display mode, the size of characters, etc., indicating the display information displayed on the liquid crystal display unit 152 can be set to normal display or enlarged display. Whether to set the size of characters, etc., indicating the display information to normal display or enlarged display can be determined by an input operation to the operation unit 16. Note that normal display is a display mode in which characters, etc., indicating the display information are displayed in a normal size (e.g., the size of 1-fold angle described later). Enlarged display is a display mode in which characters, etc., indicating the display information are displayed in a size larger than the normal display (e.g., 4 times the size). In normal display, the display information is displayed on the liquid crystal display unit 152 at once. For this reason, the number of characters of the display information is limited to below the maximum number of characters that can be displayed on the liquid crystal display unit 152 at once in normal display (the threshold number for normal display). However, in enlarged display, since the display information is scrolled and displayed, the number of characters of the display information can be set to exceed the maximum number of characters that can be displayed on the liquid crystal display unit 152 at once in enlarged display (the threshold number for enlarged display).

[0060] For example, the setting unit 171 is configured to set (change or register) the size of characters, numbers, and symbols by receiving the input of a specific symbol (e.g., -(hyphen)) via the operation unit 16. For example, when the specific symbol (-(hyphen)) is included at the beginning of the first fire information (message content) stored in the storage unit 170, the control unit 17 causes the content of the first fire information other than the specific symbol to be displayed in characters, numbers, and symbols larger than the normal display. For example, the control unit 17 causes the first fire information to be displayed on the liquid crystal display unit 152 in characters of a size 4 times that of the normal display. On the other hand, when the specific symbol is not included at the beginning of the first fire information (message content) stored in the storage unit 170, the control unit 17 causes the content of the first fire information to be displayed on the liquid crystal display unit 152 in normal display.

[0061] As described above, the control unit 17 is configured such that a plurality of display modes (e.g., normal display and enlarged display) selectable by an input operation to the operation unit 16 are set. The enlarged display is an example of a display mode in which the size (display size) of characters and the like of information within a part of the above-described range of display information is changed and displayed on the liquid crystal display unit 152. Then, the control unit 17 can display the information within the part of the range on the liquid crystal display unit 152 in accordance with the display mode (e.g., enlarged display) selected by an input operation to the operation unit 16 (i.e., by the user) among the plurality of display modes described above.

[0062] When the display mode of the display information is set to the normal display, the control unit 17 displays the entire display information at the normal size on the liquid crystal display unit 152 at once. Further, when the display mode of the display information is set to the enlarged display and the number of characters of the display information does not exceed the threshold number for enlarged display, the control unit 17 displays the display information on the liquid crystal display unit 152 at once in the enlarged display. Note that the threshold number for enlarged display is the maximum number of characters that can be displayed at once in the enlarged display on the liquid crystal display unit 152.

[0063] Further, when the display mode of the display information is set to the enlarged display and the number of characters in the display information exceeds the threshold number for enlarged display, when the control unit 17 displays the display information on the liquid crystal display unit 152, it displays the information within a partial range in the display information on the liquid crystal display unit 152 and changes the partial range within the display information. Here, the "partial range in the display information" is a display range for displaying a part of the display information, and when the display information is enlarged and displayed, it is the range of the display information that can be displayed on the liquid crystal display unit 152 at one time. Further, the "changing the partial range within the display information" means, for example, scrolling the partial range from the head side to the tail side of the enlarged display information. That is, the control unit 17 scrolls the partial range from the head side to the tail side of the display information while displaying the information within the partial range in the enlarged display information on the liquid crystal display unit 152 (for example, the entire display screen). As a result, on the liquid crystal display unit 152, the enlarged display information is scrolled and displayed from the head side to the tail side in partial ranges. In this way, when the number of characters in the display information exceeds the threshold number for enlarged display, the control unit 17 automatically changes (for example, scrolls) the partial range within the display information to scroll the entire display information and display it on the liquid crystal display unit 152. Note that the "case where the number of characters in the display information exceeds the threshold number for enlarged display" is an example of a case where a predetermined condition is satisfied.

[0064] In this way, the information within a partial range in the display information is displayed on the liquid crystal display unit 152, and the partial range is changed (for example, scrolled) within the display information. Therefore, even if the number of characters in the display information increases, it is not necessary to reduce the display size of the display information, and the visibility of the display information displayed on the liquid crystal display unit 152 can be improved. At this time, since the display information is enlarged and displayed, the visibility of the display information can be further improved.

[0065] (1.5) Specific examples of display modes Next, specific examples of the display mode will be described with reference to FIGS. 4 to 7B.

[0066] The liquid crystal display unit 152 of the display unit 15 in this embodiment includes a plurality of display areas 1520 arranged vertically and horizontally. As shown in FIG. 4, the liquid crystal display unit 152 here includes a total of 32 display areas 1520, 16 horizontally and 2 vertically. Here, the 32 display areas 1520 constitute the display screen of the liquid crystal display unit 152. Each display area 1520 is a matrix display and includes a total of 35 small areas, 5 horizontally and 7 vertically. Each small area includes, for example, a backlight (one backlight may be used for a plurality of small areas), a first polarizing plate and a second polarizing plate whose polarization directions are orthogonal to each other, and a liquid crystal layer disposed between the first and second polarizing plates. By switching each small area between a state where a voltage is applied to the liquid crystal layer and a state where no voltage is applied, the lighting state where light from the backlight is transmitted and the extinguished state where light is not transmitted can be switched.

[0067] The control unit 17 displays characters and the like on the display screen of the liquid crystal display unit 152 by turning on or off each small area and performing color separation.

[0068] In normal display, as shown in FIG. 5, the control unit 17 displays one character or the like in one display area 1520 on the display screen of the liquid crystal display unit 152, and displays the display information on the liquid crystal display unit 152. In this way, the display mode of displaying one character or the like in one display area 1520 is called 1x magnification display. The example in FIG. 5 shows an example of displaying the display information "No. 1409 KASAI HATSUSEI KAKUNIN GO ONKIYOU TEISHI" in normal display (i.e., 1x magnification display).

[0069] On the other hand, in enlarged display (when displaying larger than normal display), the control unit 17 uses two or more display areas out of the plurality of display areas 1520, here four display areas 1520, to display one character or the like. The display mode of using four display areas 1520 to display one character or the like in this way is called 4x magnification display.

[0070] For enlargement display, for example, in the storage unit 170, dedicated symbols for enlargement display (hereinafter referred to as "foreign characters") E1 to E8 are stored (see FIG. 6). For example, the foreign character E1 is a symbol that is displayed with the leftmost two columns (a total of 14) of the 35 small areas in the display area 1520 in the off state and the remaining small areas in the on state. Further, the foreign character E2 is a symbol that is displayed with the upper left four and lower left four (a total of eight) of the 35 small areas in the display area 1520 in the off state and the remaining small areas in the on state. Although not shown in the figure, a display with all 35 small areas in the on state is also stored as the foreign character E0. In the master unit 1 of the present embodiment, these foreign characters E0 to E8 are appropriately displayed in a total of four display areas 1520 with two rows horizontally and two columns vertically to perform enlargement display.

[0071] For example, when magnifying and displaying the number 0, the superscript characters E6, E1, E7, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7A). When magnifying and displaying the number 1, the superscript characters E0, E1, E0, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7B). When magnifying and displaying the number 2, the superscript characters E4, E1, E7, and E3 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7C). Similarly, when magnifying and displaying the number 4, the superscript characters E7, E1, E0, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7D). When magnifying and displaying the number 5, the superscript characters E4, E7, E8, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7F). When magnifying and displaying the number 6, the superscript characters E4, E2, E7, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7G). When magnifying and displaying the number 7, the superscript characters E6, E1, E0, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7H). When magnifying and displaying the number 8, the superscript characters E5, E1, E7, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (see FIG. 7I). When magnifying and displaying the number 9, the superscript characters E5, E1, E8, and E1 may be respectively displayed in the four display areas 1520 at the upper left, upper right, lower left, and lower right (FIG. 7J).

[0072] Thus, the liquid crystal display unit 152 includes a total of 32 display areas 1520 arranged horizontally in 16 columns and vertically in 2 rows. Therefore, in normal display, the liquid crystal display unit 152 can display a maximum of 32 characters or the like at a time, and in magnified display, it can display a maximum of 8 characters or the like at a time. In this embodiment, as an example, in normal display, the number of characters in the display information is limited to 32. In this case, the above-mentioned threshold number for normal display is 32, the above-mentioned threshold number for magnified display is 8, and the above-mentioned certain range is the range corresponding to 8 characters in magnified display. In magnified display, the number of characters in the display information is not particularly limited.

[0073] In this embodiment, when the number of characters in the display information (e.g., "No. 1409") does not exceed the threshold number for enlarged display (e.g., 8 characters) in the enlarged display, as shown in FIG. 8A, the control unit 17 displays the display information on the liquid crystal display unit 152 at once. Also, when the number of characters in the display information (e.g., "No. 1409 KASAI HATSSEI KAKUNIN GO ONKIYOU TEISHI") exceeds 8 characters, for example, in the enlarged display, as shown in FIG. 8B, the information in a partial range (range of 8 characters) R1 in the display information is displayed on the liquid crystal display unit 152, and the partial range R1 is changed (e.g., scrolled) within the display information. Thereby, the control unit 17 scrolls the display information one character at a time from the first 8 characters to the last 8 characters and displays it on the liquid crystal display unit 152.

[0074] (1.6) Operation Explanation Next, the operation of the master unit 1 (more specifically, the operation of the control unit 17 when displaying the display information on the liquid crystal display unit 152) will be described with reference to FIG. 9.

[0075] When the control unit 17 receives a fire alarm via the receiving unit 14 (S1), it determines whether the display mode of the display information is set to normal display or enlarged display based on the setting of the setting unit 171 (S2). As a result of this determination, when the display mode of the display information is set to normal display (S2: normal display), the control unit 17 displays the display information on the liquid crystal display unit 152 in normal display (S3). In this case, when the display information is, for example, "No. 1409 KASAI HATSSEI KAKUNIN GO ONKIYOU TEISHI", as shown in FIG. 5, the display information is displayed on the liquid crystal display unit 152 in normal display. Then, the process ends.

[0076] On the other hand, if the display mode of the display information is set to enlarged display as a result of the determination in step S2 (S2: enlarged display), the control unit 17 determines whether the number of characters in the display information exceeds the threshold number for enlarged display (S4). If, as a result of this determination, the number of characters in the display information does not exceed the above threshold number (S4: NO), the control unit 17 displays the display information on the liquid crystal display unit 152 at once in enlarged display. In this case, when the display information is, for example, "No. 1409", as shown in Fig. 8A, the display information is displayed on the liquid crystal display unit 152 at once in enlarged display. Then, the process ends.

[0077] On the other hand, if, as a result of the determination in step S4, the number of characters in the display information exceeds the above threshold number (S4: YES), the control unit 17 displays the information within a partial range R1 in the display information on the liquid crystal display unit 152 in enlarged display, and changes the partial range R1 within the display information (for example, scrolls one character at a time from the first 8 characters to the last 8 characters of the display information). Thereby, the display information is scrolled in enlarged display and displayed on the liquid crystal display unit 152. In this case, when the display information is, for example, "No. 1409 KASAI HATSSEI KAKUNIN GO ONKIYOU TEISHI", first, the first 8 characters of the display information ("No. 1409 KASA") are displayed on the liquid crystal display unit 152 in enlarged display, and then, it is scrolled one character at a time from the head side to the tail side of the display information in enlarged display, and the last 8 characters "ONKIYOU TEISHI" are displayed (see Fig. 8B). Then, the process ends.

[0078] (1.7) Main effects The master device 1 (receiver) according to this embodiment includes a receiving unit 14, a display unit 15, and a control unit 17. The receiving unit 14 receives a signal notified from the sensor 2. The display unit 15 displays display information based on the signal received by the receiving unit 14. The control unit 17 displays the information within a partial range R1 in the display information on the display unit 15 (more specifically, the liquid crystal display unit 152), and changes the partial range R1 within the display information. According to this configuration, since the information within a partial range R1 in the display information is displayed on the display unit 15 and the partial range R1 is changed within the display information, even if the number of characters in the display information increases, the display information can be displayed on the display unit 15 without reducing the size of the display information. As a result, even if the number of characters in the display information increases, the visibility of the display information displayed on the display unit 15 can be improved.

[0079] (2) Modification The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. Further, a function similar to that of the control unit 17 of the master device 1 may be embodied by a control method, a computer program, or a non-transitory recording medium on which the computer program is recorded.

[0080] A control method according to one aspect includes a reception process, a display process, and a control process. In the reception process, a signal notified from the sensor 2 is received. In the display process, display information is displayed on the display unit 15 (more specifically, the liquid crystal display unit 152) based on the signal received in the reception process. In the control process, the information within a partial range R1 in the display information is displayed on the display unit 15, and the partial range R1 is changed within the display information.

[0081] Further, a program according to one aspect is a program that causes a computer system to execute the above control method.

[0082] (Modification 1) In the above-described embodiment, in normal display, the number of characters of the display information is limited within the threshold number for normal display (i.e., the maximum number of characters that can be displayed on the liquid crystal display unit 152 in normal display, for example, 32 characters), but it may exceed the above-described threshold number of the display information in normal display. In this case, when the display information is set to normal display, the control unit 17 determines whether the number of characters of the display information exceeds the above-described threshold number. As a result of this determination, when the number of characters of the display information exceeds the above-described threshold number, the control unit 17 displays, in normal display, information within a partial range of the display information on the liquid crystal display unit 152 and changes (for example, scrolls) the partial range within the display information. The above-described partial range is, for example, the maximum number of characters that can be displayed on the liquid crystal display unit 152 in normal display. Also, the above-described partial range can be moved (for example, scrolled) one character at a time from the head side to the tail side of the display information. Thereby, the entire display information is scrolled and displayed on the liquid crystal display unit 152. Note that, as a result of the above-described determination, when the number of characters of the display information does not exceed the above-described threshold number, the control unit 17 displays the display information on the liquid crystal display unit 152 at once in normal display.

[0083] According to this modification example, even when the number of characters of the display information increases in normal display, the display information can be displayed on the display unit 15 without being reduced. As a result, even when the number of characters of the display information increases in normal display, the visibility of the display information displayed on the display unit 15 can be improved.

[0084] (Modification Example 2) In the above-described embodiment, the case where a partial range R1 of the display information is scrolled within the display information in enlarged display is exemplified. However, the display information may be divided into a plurality of parts, and the control unit 17 may display the plurality of parts one by one in order as information within the partial range R1 on the liquid crystal display unit 152. For example, when the display information is "1409th, KASAI HATSSEI, KAKUNIN GO, ONKIYOU TEISHI", the display information is divided into four parts: "1409th", "KASAI HATSSEI", "KAKUNIN GO", and "ONKIYOU TEISHI". Then, these four divisions are displayed on the liquid crystal display unit 152 one by one in order from the first to the fourth. In this way, the plurality of parts of the expression information are displayed on the liquid crystal display unit 152 one by one in order.

[0085] Note that Modification Example 2 is applicable when enlarged display is performed, but it may also be applicable when normal display is performed as in Modification Example 1.

[0086] Even with this modification example, even if the number of characters in the display information increases, the display information can be displayed on the display unit 15 without being reduced in size. As a result, even if the number of characters in the display information increases, the visibility of the display information displayed on the display unit 15 can be improved.

[0087] (Modification Example 3) In the above embodiment, 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 control unit 17 is controlled based on a signal from the external device received via the communication I / F 19. More specifically, the control unit 17 causes the display unit 15 (the display lamp 151 or the liquid crystal display unit 152) to display the information received from the external device as display information, or changes the setting of the setting unit 171 according to the control received from the external device. Thereby, the master unit 1 can be controlled by information from the outside.

[0088] (Modification Example 4) In the above embodiment, when the display information is displayed on the display unit 15 in an enlarged display, if the number of characters in the display information always exceeds the threshold number for enlarged display, the control unit 17 always automatically changes a partial range R1 within the display information when the display information is enlarged and displayed on the display unit 15. In this case, the above "when the display information is enlarged and displayed on the display unit 15" is an example of a case where a predetermined condition is satisfied.

[0089] (Other Modification Examples) In the automatic fire alarm system 100 according to the present disclosure, the control unit 17 of the master unit 1 includes a computer system. The computer system mainly includes a processor and a memory as hardware. By the processor executing a program recorded in the memory of the computer system, the functions as the control unit 17 of the master unit 1 in the present disclosure are 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 in 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, the integrated circuits such as the IC or LSI have different names 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 one or more 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 in a plurality of devices. The computer system 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.

[0090] Moreover, the fact that multiple functions in the control unit 17 of the master device 1 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 dispersedly in multiple housings. Furthermore, at least some functions of the control unit 17 may be realized by a cloud (cloud computing) or the like.

[0091] The display unit 15 is not limited to the liquid crystal display unit 152 using the matrix display shown in FIG. 4. For example, the display unit 15 may include a 7-segment display instead of the display area 1520 of the liquid crystal display unit 152.

[0092] The setting unit 171 may be able to set the colors of characters, numbers, and symbols indicating the fire information displayed on the display unit 15 (liquid crystal display unit 152).

[0093] Also, the automatic fire alarm system 100 of the above embodiment is exemplified when applied to a P-type automatic fire alarm system, but it may also be applied to an R-type automatic fire alarm system.

[0094] (3) Aspect As is clear from the embodiments and modifications described above, the following aspects can be taken.

[0095] The receiver (1) of the first aspect includes a receiving unit (14), a display unit (15), and a control unit (17). The receiving unit (14) receives a signal notified from the sensor (2). The display unit (15) displays display information based on the signal received by the receiving unit (14). The control unit (17) displays the information within a partial range (R1) in the display information on the display unit (15) and changes the partial range (R1) within the display information.

[0096] According to this configuration, since information within a partial range (R1) in the display information is displayed on the display unit (15) and the partial range (R1) is changed within the display information, even if the number of characters in the display information increases, the display information can be displayed on the display unit (15) without being reduced in size. As a result, even if the number of characters in the display information increases, the visibility of the display information displayed on the display unit (15) can be improved.

[0097] In the receiver (1) according to the second aspect, in the first aspect, the display information is information composed of at least one of characters, numbers, and symbols.

[0098] According to this configuration, it is applicable to display information composed of at least one of characters, numbers, and symbols.

[0099] In the receiver (1) according to the third aspect, in the first or second aspect, when a predetermined condition is satisfied, the control unit (17) changes a partial range (R1) within the display information.

[0100] According to this configuration, when a predetermined condition is satisfied, the partial range (R1) can be automatically changed within the display information.

[0101] In the receiver (1) according to the fourth aspect, in the third aspect, when the number of characters in the display information exceeds a threshold number, the control unit (17) automatically changes a partial range (R1) within the display information.

[0102] According to this configuration, when the number of characters in the display information exceeds a threshold number, the partial range (R1) can be automatically changed within the display information.

[0103] In the receiver (1) according to the fifth aspect, in the third or fourth aspect, when the control unit (17) enlarges the display information and displays it on the display unit (15), the control unit (17) changes a partial range (R1) within the display information.

[0104] According to this configuration, when the display information is enlarged and displayed on the display unit (15), the partial range (R1) can be changed within the display information.

[0105] In the receiver (1) of the sixth aspect, in any one of the first to fifth aspects, the control unit (17) displays the information within a partial range (R1) on the display unit (15) according to the display mode selected by the user among the plurality of display modes.

[0106] According to this configuration, the information within a partial range (R1) can be displayed on the display unit (15) in the display form selected by the user among the plurality of display forms.

[0107] In the receiver (1) of the seventh aspect, in the sixth aspect, the plurality of display modes include a display mode that enables the display unit (15) to display the information within a partial range (R1) while being able to change the display size.

[0108] According to this configuration, the operator can select, from among the plurality of display modes, a display mode that enables the display unit (15) to display the information within a partial range (R1) while being able to change the display size.

[0109] In the receiver (1) of the eighth aspect, in the first to seventh aspects, the control unit (17) changing a partial range (R1) within the display information includes a change of scrolling the partial range (R1) within the display information.
