[Figure 2] 1A and 1B are diagrams illustrating examples of displays on a fire alarm receiver and a mobile terminal of a fire alarm system according to an embodiment. [Figure 3] 10 is a flowchart illustrating the operation of the fire receiver according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments, and various modifications are possible without departing from the spirit of the present invention. Furthermore, the present invention includes all possible combinations of the configurations shown in the following embodiments. Furthermore, the device shown in the drawings is an example of the device of the present invention, and the device of the present invention is not limited to the device shown in the drawings. Furthermore, in each drawing, parts with the same reference numerals are the same or equivalent, and this is common throughout the entire specification.

[0010] Embodiment FIG. 1 is a diagram illustrating the configuration of a fire alarm system 100 according to an embodiment. The fire alarm system 100 includes a fire receiver 1, a fire detector 3 and a transmitter 4 connected to the fire receiver 1 via a detector line 2, a display 5 connected to the fire receiver 1 via a display line 6, and a mobile terminal 7. The fire receiver 1 and the mobile terminal 7 are communicatively connected. The fire receiver 1, the transmitter 4, and the display 5 are an example of a fire alarm system equipped with an operation unit and a display unit. Note that the number of detector lines 2 and display lines 6 shown in the figure is an example, and the numbers are not limited to those shown.

[0011] The fire detector 3 is, for example, a heat detector, a smoke detector, or a flame detector. When the fire detector 3 detects a change in a physical phenomenon caused by a fire, it changes the open / close state of the contacts connected to the detector circuit 2, thereby changing the voltage of the detector circuit 2. The fire receiver 1 monitors the voltage of the detector circuit 2, and acquires (receives) the voltage change caused by the fire detector 3 changing the open / close state of the contacts as a fire alarm signal. Note that in this embodiment, an example will be described in which the fire receiver 1 is a P-type fire receiver that uses a voltage change, which is a signal common to each fire detector 3, as an alarm signal, but the fire receiver 1 may also be an R-type fire receiver.

[0012] The transmitter 4 is a device that transmits a fire signal to the fire receiver 1 when a person who discovers a fire presses the push button that serves as the operating unit. When the push button is pressed, the voltage of the detector line 2 connected to the fire receiver 1 changes. The fire receiver 1 monitors the voltage of the detector line 2, and acquires (receives) the change in voltage that occurs when the push button is pressed as a fire signal. The transmitter 4 also has an indicator light that serves as an indicator to show the presence of the transmitter 4.

[0013] The display device 5 is a device that displays information about the sensor line 2 on which the alarm signal has been generated. The display device 5 is connected to the fire receiver 1 via a display line 6, and acquires the alarm signal or information about the sensor line 2 on which the alarm signal has been generated from the fire receiver 1, and displays information indicating the sensor line 2 on the display unit. For example, the display device 5 has indicator lights corresponding to each of the sensor lines 2, and turns on the indicator light corresponding to the sensor line 2 on which the alarm signal has been generated. Alternatively, the display device 5 is equipped with a liquid crystal display or an organic EL display, and displays the sensor line 2 on which the alarm signal has been generated. The display device 5 may also be equipped with a hardware button or a touch panel as an operation unit for stopping the sound of the sound device that notifies of the occurrence of a fire.

[0014] In addition to the fire detector 3, transmitter 4 and display 5, the fire receiving device 1 may be connected to alarm devices such as bells, buzzers or lights, smoke control devices such as fire doors or shutters, or fire extinguishing equipment.

[0015] The fire receiver 1 includes a control unit 10, a transmission circuit 11, a transmission circuit 12, an operation unit 13, a display unit 14, a camera 15, a person recognition means 16, a communication unit 17, and a memory unit 18.

[0016] When an alarm signal from the fire detector 3 is input, the control unit 10 activates a bell, an alarm device, a smoke control device, or fire extinguishing equipment. When a fire is reported by the bell or alarm device, a person in charge of the fire receiver 1 visually checks whether or not a fire has occurred. The person in charge, who has confirmed that a fire has occurred, presses the push button on the transmitter 4, and upon receiving the fire signal from the transmitter 4, the fire receiver 1 determines that a fire has occurred. In addition, when alarm signals are sent from multiple fire detectors 3 to one detector line 2, it may be determined that a fire has occurred.

[0017] Furthermore, the control unit 10 periodically transmits a request signal to the fire detector 3, requesting the fire detector 3 to transmit an analog value. The fire detector 3 transmits the analog value in response to the request signal. The cycle for requesting the fire detector 3 to transmit the analog value may differ depending on the type of fire detector 3, such as smoke, heat, or flame, or may differ depending on the installation location of the fire detector 3.

[0018] The control unit 10 is configured by a dedicated control circuit, or a CPU (Central Processing Unit) that executes programs stored in memory, or a combination of these. When the control unit 10 is a CPU, each function executed by the control unit 10 is realized by software, firmware, or a combination of software and firmware. A table that associates each of the sensor lines 2 with information indicating the installation location of that sensor line 2 is stored in the memory provided in the control unit 10.

[0019] The transmission circuit 11 is provided for each of the sensor lines 2 to which the fire detector 3 and the transmitter 4 are connected, and receives the alarm signal from the sensor line 2 and the fire signal from the transmitter 4, and sends the received signal to the control unit 10.

[0020] The transmission circuit 12 is provided corresponding to the display line 6 to which the display 5 is connected. The transmission circuit 12 sends to the display 5 information output from the control unit 10 regarding the detector line 2 on which an alarm signal or a fire signal has been generated.

[0021] The operation unit 13 includes hardware buttons provided on the housing of the fire control device 1 and a touch panel provided over the display of the display unit 14. The operation unit 13 accepts operations from the user and sends signals corresponding to the operations to the control unit 10. The hardware buttons provided on the operation unit 13 are provided with nameplates indicating the functions of the buttons.

[0022] The display unit 14 includes a liquid crystal display, an organic EL display, or a lamp provided on the housing of the fire receiving device 1. The display unit 14 displays the sensor line 2 or the fire sensor 3 from which the alarm signal has been generated. The display unit 14 of this embodiment displays information indicating the operation location on the touch panel of the operation unit 13.

[0023] The camera 15 is a device that captures images using an imaging element, for example, a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor. The camera 15 is installed in a position where it can capture an image in front of the operation unit 13. In this embodiment, an example is shown in which the camera 15 is built into the housing of the fire control panel 1, but the installation location of the camera 15 is not limited to this. The camera 15 may be externally attached to the housing of the fire control panel 1, or may be installed in a location separate from the fire control panel 1. The image data captured by the camera 15 is input to the person recognition means 16. Here, the image data refers to a collection of images captured by the camera 15.

[0024] The person recognition means 16 recognizes whether or not a person is present in the captured data based on the captured data obtained from the camera 15. Because the camera 15 captures an image in front of the operation unit 13, the person recognition means 16 recognizes the presence of a person in front of the operation unit 13. The person recognition means 16 has, for example, a database of information about human faces, and recognizes whether or not a human face is present in the image by comparing feature points contained in the image of the captured data with the database. The person recognition means 16 has a memory for storing the database and a dedicated circuit for recognizing people. The person recognition means 16 may be provided separately from the fire control device 1, in which case the recognition result of the person recognition means 16 is input to the control unit 10 of the fire control device 1.

[0025] The communication unit 17 is a communication circuit that communicates with the mobile terminal 7. The communication unit 17 transmits a signal output from the control unit 10 to the mobile terminal 7, and receives a signal transmitted from the mobile terminal 7.

[0026] The storage unit 18 is an internal storage memory, an external storage medium such as a memory card, or a combination thereof. The storage unit 18 stores additional information 81, which will be described later.

[0027] The mobile terminal 7 includes a control unit 70, a display device 71, an input unit 72, and a communication unit 73. The mobile terminal 7 is a portable information processing device such as a smartphone, a tablet terminal, or a notebook computer.

[0028] The control unit 70 displays information received from the fire receiver 1 by the communication unit 73 on the display device 71. Display on the display device 71 will be described later. The control unit 70 also transmits a signal based on an input to the input unit 72 to the fire receiver 1 via the communication unit 73. The control unit 70 is configured by a dedicated control circuit, or a CPU (Central Processing Unit) that executes a program stored in memory, or a combination of these. When the control unit 70 is a CPU, each function executed by the control unit 70 is realized by software, firmware, or a combination of software and firmware.

[0029] The display device 71 is a device that displays information to the user of the mobile terminal 7. The display device 71 is, for example, a liquid crystal display or an organic EL display.

[0030] The input unit 72 is a device that accepts operational inputs from the user of the mobile terminal 7. The input unit 72 is, for example, a touch panel or hardware buttons.

[0031] The communication unit 73 is a communication circuit that communicates with the fire control device 1. The communication unit 73 transmits signals output from the control unit 70 to the fire control device 1, and receives signals transmitted from the fire control device 1.

[0032] In the fire alarm system 100 of this embodiment, the mobile terminal 7 displays images of the operation unit 13 and display unit 14 of the fire receiving device 1, as well as additional information related to the operation unit 13 and display unit 14. A user who operates the fire receiving device 1 holds the mobile terminal 7 and checks or operates the fire receiving device 1 by referring to the images and additional information of the operation unit 13 and display unit 14 displayed on the mobile terminal 7. In other words, the mobile terminal 7 functions as a guide when checking or operating the fire receiving device 1. This will be explained in detail below.

[0033] 2A and 2B are diagrams illustrating examples of displays on the fire receiver 1 and the mobile terminal 7 of the fire alarm system 100 according to the embodiment. Fig. 2A shows an example of the appearance of the display unit 14 and operation units 13A and 13B of the fire receiver 1, and Fig. 2B shows an example of a display on the display device 71 of the mobile terminal 7.

[0034] As shown in FIG. 2(A), the fire control receiver 1 includes a display unit 14, and operation units 13A and 13B. The operation units 13A and 13B embody the operation unit 13 shown in FIG. 1. The operation unit 13A is a touch panel, and the operation unit 13B is a hardware button. In the following, when there is no need to distinguish between the operation units 13A and 13B, they will be simply referred to as the operation unit 13. Characters or figures, etc. displayed on the display unit 14 are schematically indicated by an "X." Characters or figures, etc. on nameplates displayed on the operation units 13A and 13B are also schematically indicated by an "X."

[0035] As shown in FIG. 2(B), an image 80 and additional information 81 are displayed on the display device 71 of the mobile terminal 7.

[0036] Image 80 is an image showing the appearance of display unit 14 and operation unit 13 of fire receiving device 1. Image 80 may be an image of display unit 14 and operation unit 13 that has been photographed in advance. Alternatively, if mobile terminal 7 is equipped with a camera (not shown), an image of display unit 14 and operation unit 13 photographed by this camera may be displayed on display device 71 in real time as image 80.

[0037] The additional information 81 is intended for either or both of the display unit 14 and the operation unit 13. Specifically, the additional information 81 includes at least one of the following: characters displayed on the display unit 14 in another language; characters on the nameplate of the operation unit 13 in another language; detailed information about the display unit 14; and information about how to operate the operation unit 13. The detailed information about the display unit 14 includes supplementary explanations of the characters displayed on the display unit 14, points to check when the user checks, or the order of operations. In FIG. 2, the characters displayed in the additional information 81 are schematically represented by "Y." Note that the additional information 81 is not limited to characters and may be a figure. Furthermore, a hyperlink may be embedded in the additional information 81, and an explanation page may be displayed when the hyperlink is operated.

[0038] The additional information 81 is stored in advance in the storage unit 18 of the fire receiving device 1, and when the conditions shown in Fig. 3 described later are met, it can be transmitted from the fire receiving device 1 to the mobile terminal 7 and displayed on the display device 71 of the mobile terminal 7. An example of operation will be described below.

[0039] Fig. 3 is a flowchart illustrating the operation of the fire receiving device 1 according to the embodiment. The operation of the fire receiving device 1 for displaying additional information 81 on the display device 71 of the mobile terminal 7 will be described with reference to Fig. 3. It is assumed that communication between the fire receiving device 1 and the mobile terminal 7 has been established in advance.

[0040] When the user of the mobile terminal 7 wants to display additional information 81 on the display device 71, the user operates the input unit 72 to transmit a display request signal requesting the display of additional information 81 to the fire control panel 1.

[0041] (S1) It is determined whether or not a display request signal for the additional information 81 has been received from the mobile terminal 7. If a display request signal for the additional information 81 has been received (S1: YES), the process proceeds to step S2, and if not (S1: NO), the process proceeds to step S4.

[0042] (S2) It is determined whether a first condition is satisfied. Here, the first condition is a condition for determining whether or not to permit the mobile terminal 7 to display additional information 81. By displaying additional information 81 on mobile terminal 7 only when the first condition is satisfied, it is possible to display additional information 81 only on specific mobile terminals 7, even if additional information 81 contains information that should not be unnecessarily made public, such as information specific to the building in which the fire control receiver 1 is installed. This makes it possible to strengthen security regarding the display of additional information 81.

[0043] A first example of the first condition is the distance between the fire receiver 1 and the mobile terminal 7. The first condition is met when the distance between the fire receiver 1 and the mobile terminal 7 is equal to or less than a threshold value. In other words, the additional information 81 is displayed on the mobile terminal 7 that is within a predetermined range (threshold value) from the fire receiver 1. The distance between the fire receiver 1 and the mobile terminal 7 can be detected using a GPS receiving unit that receives GPS (Global Positioning System) radio waves provided in each of the fire receiver 1 and the mobile terminal 7. Alternatively, when the fire receiver 1 and the mobile terminal 7 communicate wirelessly via Wi-Fi, Bluetooth (registered trademark), or the like, the radio wave intensity can also be used to detect the distance between the fire receiver 1 and the mobile terminal 7.

[0044] A second example of the first condition is whether or not there is a person in front of the operation unit 13 of the fire receiving device 1. The first condition is met when a person is recognized by the camera 15 and the person recognition means 16. In other words, when there is a person in front of the operation unit 13 of the fire receiving device 1, the additional information 81 is displayed on the mobile terminal 7. Note that the distance between the fire receiving device 1 and the mobile terminal 7 and the presence or absence of a person may be combined.

[0045] A third example of the first condition is authentication using a password. When the fire alarm control panel 1 receives a predetermined password from the mobile terminal 7, the first condition is met.

[0046] (S3) Additional information 81 is transmitted from the fire receiving device 1 to the mobile terminal 7. If the additional information 81 includes information in multiple languages, the user may be able to select the language in which the information is to be displayed. For example, before transmitting the additional information 81 to the mobile terminal 7 in step S3, the fire receiving device 1 transmits a signal to the mobile terminal 7 requesting selection of a display language, and the mobile terminal 7 displays a question such as, "Which language would you like to display: English, Chinese, or Spanish?" When the user operates the input unit 72 of the mobile terminal 7 to select a language, a signal specifying the selected language is transmitted from the mobile terminal 7 to the fire receiving device 1. Then, the fire receiving device 1 transmits information in the selected language from the information in multiple languages ​​stored in the memory unit 18 to the mobile terminal 7 as additional information 81. The display language may be selected automatically based on the language setting configured in the mobile terminal.

[0047] (S4) It is determined whether an input signal to the fire receiver 1 transmitted from the mobile terminal 7 has been received. In this embodiment, operation input can be made to the fire receiver 1 from the mobile terminal 7. That is, by operating the input unit 72 while looking at the display device 71 of the mobile terminal 7, input can be made to the operation unit 13 of the fire receiver 1 without the user actually operating the operation unit 13. It is determined whether or not there is an input signal to the fire receiver 1. If an input signal to the fire receiver 1 has been received (S4: YES), proceed to step S5; if not (S4: NO), return.

[0048] (S5) It is determined whether or not a second condition is satisfied. Here, the second condition is a condition for determining whether or not an input signal from the mobile terminal 7 to the fire control device 1 is accepted as an operation on the fire control device 1. By accepting an input signal from the mobile terminal 7 to the fire control device 1 only when the second condition is satisfied, unintentional operation of the fire control device 1 by the mobile terminal 7 is prevented. This makes it possible to strengthen security regarding the operation of the fire control device 1.

[0049] Specific examples of the second condition are the same as the first, second, and third examples of the first condition, and will not be described again. The first condition and the second condition may be the same or different. When the first condition and the second condition are the same, if the first condition is satisfied in step S2, the process of determining whether the second condition is satisfied in step S5 may be omitted.

[0050] (S6) The fire control signal receiver 1 receives an input signal transmitted from the mobile terminal 7 and performs an operation based on this input signal.

[0051] As described above, the fire alarm system 100 of this embodiment includes the fire receiver 1, which is a fire alarm system equipped with the display unit 14 and the operation unit 13, and the mobile terminal 7 that communicates with the fire receiver 1. The mobile terminal 7 includes a display device 71 that displays an image 80 of the display unit 14 and the operation unit 13 of the fire receiver 1, along with additional information 81 for either or both of the display unit 14 and the operation unit 13. This allows a user monitoring or operating the fire receiver 1 to easily monitor or operate the fire receiver 1 by referring to the additional information 81 displayed on the mobile terminal 7. This reduces user errors in monitoring or operating the fire receiver 1 and improves the speed of monitoring and operation. Furthermore, the mobile terminal 7 can be used for training in monitoring and operating the fire receiver 1, thereby efficiently improving user proficiency.

[0052] Furthermore, in the fire alarm system 100 of this embodiment, the display device 71 of the mobile terminal 7 displays information relating to the operation unit 13B, which is a hardware button of the fire receiver 1, as additional information 81. The nameplates of the hardware buttons of the fire receiver 1 are generally displayed in a fixed manner by printing or engraving, but by displaying the additional information 81 on the mobile terminal 7, even a user who is unfamiliar with the fire receiver 1 can more reliably monitor and operate the fire receiver 1.

[0053] Furthermore, the display device 71 of the mobile terminal 7 of this embodiment displays either or both of the text displayed on the display unit 14 of the fire receiving device 1 in a different language and the information related to the operation unit 13 in a different language as additional information 81. Therefore, even if a user who monitors or operates the fire receiving device 1 is unfamiliar with the display language of the display unit 14 or the operation unit 13 of the fire receiving device 1, the user can more reliably monitor and operate the fire receiving device 1 by displaying the familiar language as additional information 81.

[0054] Furthermore, the display device 71 of the mobile terminal 7 in this embodiment displays the additional information 81 when the distance between the fire control signal 1 and the mobile terminal 7 is equal to or less than a threshold. Since the additional information 81 is displayed on the mobile terminal 7 when the user using the mobile terminal 7 is at a distance from the fire control signal 1 that is equal to or less than the threshold, the additional information 81 can be delivered to a user who is actually near the fire control signal 1 and needs the additional information 81. Furthermore, since the additional information 81 is not displayed on a mobile terminal 7 that is located at a distance from the fire control signal 1 that exceeds the threshold, unintended leakage of the additional information 81 can be prevented.

[0055] Furthermore, the fire alarm system 100 of this embodiment is equipped with a camera 15 that captures an image in front of the operation unit 13 of the fire receiving device 1, and a person recognition means 16 that recognizes the presence of a person in front of the operation unit 13 of the fire receiving device 1 based on the image data obtained from the camera 15. Then, the display device 71 of the mobile terminal 7 displays additional information 81 when the person recognition means 16 recognizes the presence of a person. Because the additional information 81 is displayed on the mobile terminal 7 when a person is near the operation unit 13 of the fire receiving device 1, unintended leakage of the additional information 81 can be prevented.

[0056] When additional information 81 is displayed on mobile terminal 7, this fact may be displayed on display unit 14 of fire receiving device 1. In this way, even if an unexpected third party views additional information 81 via mobile terminal 7, the user monitoring fire receiving device 1 in front of the third party can notice this, thereby preventing information from leaking to the third party.

[0057] The fire alarm system 100 of this embodiment also includes a camera 15 that captures an image in front of the operation unit 13 of the fire receiver 1, and a person recognition means 16 that recognizes the presence of a person in front of the operation unit 13 of the fire receiver 1 based on the image data obtained from the camera 15. The mobile terminal 7 transmits an input signal to the fire receiver 1, and the fire receiver 1 accepts the input signal transmitted from the mobile terminal 7 when the person recognition means 16 recognizes the presence of a person. Because the fire receiver 1 accepts the input signal from the mobile terminal 7 when a person is near the operation unit 13 of the fire receiver 1, it is possible to prevent unintended operation of the fire receiver 1 by a user who is located far from the fire receiver 1.

[0058] [Modification of the fire alarm system 100] The following describes a modified example of the fire alarm system 100 of this embodiment. In the following description, the same components as those described in the embodiment are denoted by the same reference numerals.

[0059] (Method for acquiring additional information 81 by mobile terminal 7) In the embodiment, it has been described that the storage unit 18 of the fire receiving device 1 stores the additional information 81, and that when the additional information 81 is to be displayed on the mobile terminal 7, the additional information is transmitted from the fire receiving device 1 to the mobile terminal 7. However, the additional information 81 may be pre-stored in the mobile terminal 7. The mobile terminal 7 displays the additional information 81 stored therein when the first condition in FIG. 3 is satisfied. Alternatively, the fire alarm system 100 may include a server communicatively connected to the fire receiving device 1 and the mobile terminal 7, and the additional information 81 may be stored in this server. In this case, when the first condition in FIG. 3 is satisfied, the fire receiving device 1 transmits a signal to the server instructing it to transmit the additional information 81 to the mobile terminal 7, and the server, upon receiving this signal, transmits the additional information 81 to the mobile terminal 7. Even with such a configuration, it is possible to obtain the same advantageous effects as those of the embodiment.

[0060] (Function for fire alarm receiver 1 in mobile terminal 7) In the embodiment, it has been described that the mobile terminal 7 displays the additional information 81 when the first condition is satisfied, and that the fire receiving device 1 accepts an input signal from the mobile terminal 7 when the second condition is satisfied. However, the mobile terminal 7 may display the additional information 81 regardless of whether the first condition is satisfied. Furthermore, the fire receiving device 1 may not accept an input signal from the mobile terminal 7 regardless of whether the second condition is satisfied. In this way, unintended remote control of the fire receiving device 1 can be more reliably prevented.

[0061] (Another example of a fire alarm system) In the embodiment, an example has been described in which the fire alarm system that is the target of the additional information 81 displayed on the mobile terminal 7 is the fire receiver 1. However, this fire alarm system may also be the display unit 5. In this case, the mobile terminal 7 displays the additional information 81 of the sensor line 2 that is displayed on the display unit 5, such as information in another language or information about the location of the sensor line 2. The mobile terminal 7 and the display unit 5 may communicate via the fire receiver 1 or directly. The matters described in the embodiment apply to the display of the additional information 81 on the mobile terminal 7 and the operation of the display unit 5 using the mobile terminal 7.

[0062] The fire alarm system may also be a transmitter 4 equipped with a display unit 14 and a camera 15. In this case, the mobile terminal 7 displays, as additional information 81, for example, instructions on how to operate a push button that a person who discovers a fire should press, or information calling for caution to prevent tampering. If the transmitter 4 has a liquid crystal display or an organic EL display as a display unit, the additional information 81 displays text in a language other than the language displayed on the display unit. The mobile terminal 7 and the transmitter 4 may communicate via the fire receiving device 1 or directly. The matters described in the embodiment apply to the display of the additional information 81 on the mobile terminal 7 and the operation of the transmitter 4 using the mobile terminal 7.

[0063] (Modification of display on mobile terminal 7) The display device 71 of the mobile terminal 7 may display an image using AR (Augmented Reality) or projection AR.
