Description

Technical Field

[0001] The present disclosure relates to notification technology, and more particularly to an alarm system that notifies information about sensors and control In the device .

Background Art

[0002] In a fire alarm system, a large number of fire sensors installed in a building are connected to a fire receiver by a sensor line, and the fire receiver acquires fire detection information from each fire sensor through the sensor line. When a fire occurs, the fire receiver notifies (fires an alarm) the occurrence of the fire to an emergency contact such as a fire department through a public telephone line or the like. Some fire sensors have a self-diagnosis function for diagnosing whether their own fire detection function is normal. For example, each fire sensor periodically performs self-diagnosis and transmits the result as self-diagnosis result information to the fire receiver through the sensor line. Maintenance personnel perform maintenance based on the self-diagnosis result information. In order to facilitate the scheduling of the work of maintenance personnel, the self-diagnosis result information is also transmitted to a management device via the Internet (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] For sensors, maintenance or replacement should be carried out even if no trouble such as a failure occurs. The timing for performing such maintenance or replacement is determined starting from the timing of manufacturing the sensor or the timing of installing the sensor. The administrator must manage the timing of manufacturing the sensor or the timing of installing the sensor and grasp the maintenance timing or replacement timing.

[0005] This disclosure is made in light of these circumstances, and its purpose is to provide a technology that facilitates the determination of maintenance or replacement timing. [Means for solving the problem]

[0006] To solve the above problems, an alarm system in one aspect of the present disclosure comprises a plurality of sensors and a control device capable of communicating with each of the plurality of sensors. The control device comprises a receiving unit that receives from each of the plurality of sensors information indicating the year and month in which the sensor was manufactured and information indicating the year and month in which the sensor was installed, and an output unit that outputs a notification regarding at least one of the maintenance period and replacement period when at least one of the manufacturing period and installation period received by the receiving unit reaches its notification deadline. The output unit notifies of the arrival of at least one of the maintenance period and replacement period. When the receiving unit receives alarm information indicating a fire detected by the sensor, the output unit notifies that a fire has occurred. .

[0007] Another aspect of the present disclosure is a control device. This device is a control device capable of communicating with each of a plurality of sensors, and includes a receiving unit that receives from each of the plurality of sensors information indicating the year and month in which the sensor was manufactured and information indicating the year and month in which the sensor was installed, and an output unit that outputs a notification regarding at least one of the maintenance period and replacement period when at least one of the manufacturing period and installation period received by the receiving unit reaches its notification deadline. The output unit notifies of the arrival of at least one of the maintenance period and replacement period. When the receiving unit receives alarm information indicating a fire detected by the sensor, the output unit notifies that a fire has occurred. .

[0009] Furthermore, any combination of the above components, or any conversion of the expressions of this disclosure between methods, apparatus, systems, computer programs, or recording media on which computer programs are recorded, are also valid forms of this disclosure. [Effects of the Invention]

[0010] According to this disclosure, it is possible to easily determine the maintenance or replacement timing. [Brief explanation of the drawing]

[0011] [Figure 1] This figure shows the configuration of the alarm system according to this embodiment. [Figure 2] This diagram shows the configuration of the sensor in Figure 1. [Figure 3] This diagram shows the configuration of the control device shown in Figure 1. [Figure 4] Figures 4(a)-(c) show the data structure of the table stored in the memory unit of Figure 2. [Figure 5] Figures 5(a)-(b) show the data structure of information in the control device shown in Figure 3. [Figure 6] Figures 6(a) and 6(b) show the screens displayed on the output section of Figure 3. [Figure 7] Figure 1 is a sequence diagram showing the notification procedure by the alarm system. [Figure 8] Figure 3 is a flowchart showing the notification procedure by the control device. [Modes for carrying out the invention]

[0012] Before specifically describing the embodiments of this disclosure, an overview of these embodiments will be provided. The embodiments relate to an alarm system including a plurality of detectors (fire detectors) installed in a facility such as a building, and a control device (fire receiver) capable of communicating with each of the plurality of detectors. In the alarm system, when a detector detects the occurrence of a fire, the control device triggers a fire alarm. Until now, when managers have recorded the start date of operation and maintenance dates of the alarm system, in particular the manufacturing date and installation date of the detectors, they have used a computer or paper, which are different media from the alarm system itself. As a result, when the maintenance or replacement date approaches, several months to several years after the start of operation, it is easy for oversights to occur. In addition, detectors should be replaced every 10 to 15 years after they start of use, but the period from when a detector is manufactured until it is installed and put into operation can be long, making it difficult to determine the replacement date based on the manufacturing date alone. Furthermore, when a quality problem is discovered with a detector and it becomes necessary to find a detector that matches a specific manufacturing date, the manager has to physically inspect each installed detector one by one, which is a great deal of work.

[0013] The warning system in this embodiment notifies the administrator of the maintenance or replacement period, which occurs on an annual cycle, by storing the manufacturing date and installation date of the detector in the detector and control unit. Specifically, the manufacturing date of the detector is not only printed on the unit itself but also stored in the memory unit within the detector. Furthermore, the control unit obtains the manufacturing date from the detector via communication. This makes the manufacturing date known to the control unit and terminal devices connected to the control unit. In addition, the control unit can write maintenance and replacement information, such as the installation date and installation location, to the detector. The written installation date and location are transmitted from the detector to the control unit. This allows the control unit to know the installation date of the detector, and the installation date is also stored in the detector unit even if only the control unit is replaced.

[0014] Information such as the manufacturing date and installation date is aggregated in the control unit and server, making it possible to display this information on the control unit or receive notifications on terminal devices. Furthermore, when the manufacturing date or installation date reaches the notification deadline, the control unit outputs a notification regarding at least one of the maintenance or replacement dates. This ensures that administrators are fully aware of the information when maintenance or replacement dates are approaching.

[0015] Figure 1 shows the configuration of the alarm system 1000. The alarm system 1000 includes a sensor line 10, a network 20, sensors 100 (collectively referred to as sensors 100a, 2nd sensors 100b, ..., Nth sensor 100n), a control device 200, a fire station device 300, a server 400, and a terminal device 500. The setting device 30 may or may not be included in the alarm system 1000. Here, the sensor line 10, sensors 100, and control device 200 are installed inside the facility, while the network 20, fire station device 300, server 400, and terminal device 500 are installed outside the facility. The facility is a building that is monitored by the alarm system 1000, for example, an office building. The facility is not limited to an office building; it may be a residential unit in an apartment building, a detached house, a commercial facility, etc.

[0016] Each of the multiple rooms in the facility is equipped with a detector 100 to detect the occurrence of a fire. The multiple detectors 100 are connected in a bus-like manner via a detector circuit 10 and are connected to a control device 200. This connection allows each detector 100 to communicate with the control device 200.

[0017] FIG. 2 is a diagram showing the configuration of the sensor 100. The sensor 100 includes a communication unit 110, a control unit 120, a memory unit 130, a detection unit 140, and a speaker 150. The communication unit 110 includes a receiving unit 112 and a transmitting unit 114. The detection unit 140 detects the occurrence of a fire by detecting smoke or heat. In the case of a smoke type that detects smoke, when smoke enters the inside of the sensor 100 and the light of the light-emitting diode is reflected by the smoke particles and reaches the light-receiving unit, the occurrence of a fire is detected. Also, in the case of a heat type that detects heat, when the heat-sensitive element reaches a certain temperature, the occurrence of a fire is detected. When the control unit 120 detects the occurrence of a fire in the detection unit 140, it outputs a voice for notifying the occurrence of the fire from the speaker 150 and generates alarm information for notifying the occurrence of the fire. The alarm information includes sensor address information for identifying the sensor 100.

[0018] The transmitting unit 114 transmits the alarm information to the sensor line 10. The alarm information transmitted from the first sensor 100a in FIG. 1 is relayed in order from the second sensor 100b to the Nth sensor 100n and transmitted to the control device 200. Specifically, when the receiving unit 112 of the second sensor 100b receives the alarm information from the first sensor 100a via the sensor line 10, it outputs the alarm information to the control unit 120. The transmitting unit 114 transmits the alarm information from the control unit 120 to a third sensor 100c (not shown) via the sensor line 10. The other sensors 100 operate in the same manner. Returning to FIG. 1.

[0019] The control device 200 can communicate with a plurality of sensors 100 via the sensor line 10. FIG. 3 shows the configuration of the control device 200. The control device 200 includes a communication unit 210, a control unit 220, a storage unit 230, an input unit 240, an output unit 250, and a data communication unit 260. The communication unit 210 includes a reception unit 212 and a transmission unit 214. The control unit 220 includes a setting unit 222. The reception unit 212 receives the alarm information from the sensor 100 via the sensor line 10. The reception unit 212 outputs the alarm information to the control unit 220. The control unit 220 controls the operation of the control device 200. When the control unit 220 receives the alarm information from the reception unit 212, it outputs the alarm information from the output unit 250 or outputs the alarm information to the data communication unit 260. The output unit 250 is an interface such as a monitor or a speaker. Return to FIG. 1.

[0020] The data communication unit 260 of the control device 200 is connected to the network 20 and is connected to the fire department device 300 via the network 20. The network 20 is, for example, the Internet. The data communication unit 260 transmits the alarm information to the fire department device 300 via the network 20. The alarm information includes a unique ID for identifying the control device 200. The fire department device 300 is a device used in the fire department. When it receives the alarm information from the control device 200, it recognizes the occurrence of a fire in the facility where the control device 200 is installed based on the unique ID included in the alarm information. When the occurrence of a fire is recognized, the firefighters are urged to dispatch or a notice is sent to the police station. Here, the alarm information may not be directly transmitted to the fire department device 300 but may be transmitted to the device of the management company. In that case, the management company notifies the fire department of the occurrence of a fire.

[0021] Hereinafter, the processes for notifying the maintenance time and replacement time of the sensor 100 in such an alarm system 1000 will be described in the order of (1) the manufacturing stage, (2) the stage from construction and wiring to the start of operation, and (3) after the start of operation. Also, for (3) after the start of operation, it will be described in the order of (3-1) information collection, (3-2) information browsing, and (3-3) notification.

[0022] (1) Manufacturing stage In the manufacturing process of the detector 100, the manufacturer prints the manufacturing date on each detector 100 and writes the manufacturing date to the storage unit 130 (Figure 2) of the detector 100. The manufacturing date indicates the year and month in which the detector 100 was manufactured. The manufacturing date may also be the year in which the detector 100 was manufactured. The manufacturer also writes the part number information and type information of the detector 100 to the storage unit 130. Figures 4(a)-(c) show the data structure of the table stored in the storage unit 130. Figure 4(a) shows the data structure of the table at the time of manufacturing. The table includes part number information, type information, and manufacturing date information. Figures 4(b)-(c) will be described later.

[0023] (2) Stages from installation and wiring to commencement of operation Detectors 100 are connected to each room in the facility, and each detector 100 is connected via a detector line 10. The detector line 10 is also connected to a control device 200. The control device 200 is connected to a network 20. As a result, the configuration shown in Figure 1 is realized. In order for each detector 100 to communicate with the control device 200 via the detector line 10, each detector 100 is set with information to identify the detector 100 (hereinafter referred to as "detector address information"). For example, a DIP switch (not shown) provided on the detector 100 is used to set the detector address information. The storage unit 130 of the detector 100 stores the detector address information. Figure 4(b) shows the data structure of the table during installation and wiring. In the table, the detector address information is added to the information shown in Figure 4(a). Figure 4(c) will be described later.

[0024] The input unit 240 of the control device 200 shown in Figure 3 is an interface for administrators and users to input information, and is, for example, a button or a touch panel. After installing the detector 100, the administrator inputs the installation date information into the input unit 240. The administrator may include the construction company. The installation date indicates the year and month in which the detector 100 was installed. The installation date may be not only the year and month of installation, but also the year and month in which the warning system started operating. Alternatively, the installation date may be the year in which the detector 100 was installed. When the control unit 220 receives the installation date information from the input unit 240, it outputs the installation date information to the transmission unit 214. The transmission unit 214 transmits the installation date information to each detector 100 via the detector line 10.

[0025] The receiving unit 112 of the sensor 100 shown in Figure 2 receives installation date information via the sensor line 10. The receiving unit 112 outputs the installation date information to the control unit 120. The control unit 120 writes the installation date information to the storage unit 130. Figure 4(c) shows the data structure of the table during installation and wiring, following Figure 4(b). In the table, the installation date information is added to the information shown in Figure 4(b). In other words, the storage unit 130 stores at least the manufacturing date information and the installation date information.

[0026] As shown in Figure 1, a setting device 30 may be used to write the installation date information to the sensor 100. The setting device 30 is a device for inputting settings to the sensor 100, and has a cable for connecting to the sensor 100, as well as an interface for the administrator to input information. When the setting device 30 receives the installation date information from the administrator via the interface while the cable is plugged into the sensor 100, it transmits the installation date information to the sensor 100. As before, the control unit 120 of the sensor 100 writes the installation date information to the storage unit 130.

[0027] After the installation date information is stored in the memory unit 130 of each detector 100, the administrator inputs the notification deadline into the input unit 240 of the control device 200 in Figure 3. The notification deadline is information about the period from the manufacturing date or installation date until the maintenance or replacement date is notified, and this corresponds to a threshold value for the period from the manufacturing date or installation date. For example, the notification deadline for maintenance is entered to be every 6 months from the manufacturing date, and the notification deadline for replacement is entered to be 3 years from the installation date. The notification date is not limited to these, and below, the notification deadline for maintenance and the notification deadline for replacement will be collectively referred to as the "notification deadline". The setting unit 222 sets the notification deadline received from the input unit 240. Here, a common notification deadline may be set for multiple detectors 100, or a notification deadline may be set for each detector 100.

[0028] (3) After the start of operations (3-1) Information gathering The control unit 220 of the control device 200 in Figure 3 generates a signal (hereinafter referred to as the "request signal") to request information about the sensors 100. The transmission unit 214 transmits the request signal to each sensor 100 via the sensor line 10. The request signal may be transmitted periodically.

[0029] The receiving unit 112 of the sensor 100 in Figure 2 receives a request signal via the sensor line 10. The receiving unit 112 outputs the request signal to the control unit 120. When the receiving unit 112 receives a request signal, the control unit 120 outputs the information from the table stored in the storage unit 130 as an information signal to the transmitting unit 114. The information signal includes, for example, sensor address information, part number information, type information, manufacturing date information, and installation date information. The transmitting unit 114 transmits the information signal via the sensor line 10. When the receiving unit 112 receives a request signal or an information signal, the control unit 120 causes the transmitting unit 114 to transmit the received request signal or information signal. In other words, the request signal and information signal are forwarded sequentially to multiple sensors 100.

[0030] The receiving unit 212 of the control device 200 in Figure 3 receives information signals from each sensor 100 via the sensor line 10. In other words, the receiving unit 212 receives manufacturing date information and installation date information from each of the multiple sensors 100, as well as related information associated with the sensor 100. Related information corresponds to part number information, etc. The communication unit 210 outputs the received information signals to the control unit 220. The control unit 220 stores the contents of the information signals in the storage unit 230.

[0031] Each room in which a detector 100 is installed is assigned identification information, and the administrator inputs this identification information as installation location information into the input unit 240. The control unit 220 also stores the installation location information in the storage unit 230. Figures 5(a) and 5(b) show the data structure of the information in the control device 200. Figure 5(a) shows the data structure of the table stored in the storage unit 230. As shown, the detector address information, part number information, type information, manufacturing date information, installation date information, and installation location information for each detector 100 are stored in correspondence with each other. Figure 5(b) will be described later, and we will return to Figure 3.

[0032] Here, the control unit 220 may compare the manufacturing date information and the installation date information for one sensor 100. Since the sensor 100 is installed after it is manufactured, the manufacturing date should be earlier than the installation date. However, if an error occurs when storing the manufacturing date or installation date in the storage unit 130, the installation date will be earlier than the manufacturing date. If the installation date is earlier than the manufacturing date, the control unit 220 detects an error in at least one of the manufacturing date and installation date. In that case, the control unit 220 notifies the error from the output unit 250.

[0033] (3-2) Viewing Information The control unit 220 outputs the table stored in the storage unit 230 as sensor information to the data communication unit 260. The sensor information may include the unique ID of the control device 200. The data communication unit 260 transmits the sensor information to the server 400 (Figure 1) via the network 20. This is equivalent to transmitting the manufacturing date information, installation date information, and related information to the server 400.

[0034] The server 400 in Figure 1 can communicate with the control device 200 via the network 20 and receives sensor information from the control device 200. The server 400 stores the received sensor information. The sensor information includes sensor address information, part number information, type information, manufacturing date information, installation date information, and installation location information, all associated with a unique ID.

[0035] The terminal device 500 in Figure 1 is, for example, a smartphone, tablet device, or mobile phone device, and is used by the administrator. The terminal device 500 has a communication function and can communicate with the control device 200 via the network 20. The memory unit of the terminal device 500 stores programs that can be executed on the terminal device 500, such as application programs. One of the application programs is an application program that can execute processing in the alarm system 1000 (hereinafter referred to as the "alarm system application"). The administrator inputs a request to view sensor information by operating the terminal device 500. When the terminal device 500 receives the request, it sends a request signal to the server 400 via the network 20 to request viewing of sensor information.

[0036] When the server 400 receives a request signal from the terminal device 500 via the network 20, it transmits the stored sensor information to the terminal device 500 via the network 20. This is equivalent to informing the terminal device 500 of the manufacturing date information and installation date information in response to a request from the terminal device 500. When the terminal device 500 receives the sensor information from the server 400 via the network 20, it displays the sensor information on its screen. By viewing the screen, the administrator can recognize the sensor address information, part number information, type information, manufacturing date information, installation date information, and installation location information for each sensor 100.

[0037] (3-3)Notification The control unit 220 in Figure 3 compares at least one of the manufacturing date and installation date with the notification deadline. When at least one of the manufacturing date and installation date reaches the notification deadline, the control unit 220 determines that at least one of the maintenance date and replacement date has arrived. The control unit 220 outputs a notification from the output unit 250 to inform the user of the arrival of at least one of the maintenance date and replacement date. If the output unit 250 is a monitor, the notification will display a message informing the user that at least one of the maintenance date and replacement date has arrived, or a message prompting maintenance or replacement. Figures 6(a) and 6(b) show the screens displayed on the output unit 250. Figure 1(a) shows the message displayed when the maintenance date arrives for the first sensor 100a, and Figure 1(b) shows the message displayed when the replacement date arrives for the first sensor 100a.

[0038] Furthermore, if the output unit 250 is a speaker, a voice message is output as a notification to inform the user that at least one of the maintenance period and replacement period has arrived, or a voice message prompting maintenance or replacement. Such notifications may be given to multiple sensors 100 collectively, or to each sensor 100 individually.

[0039] When the control unit 220 determines that at least one of the maintenance period and replacement period has arrived, it outputs a signal (hereinafter referred to as the "notification signal") to the data communication unit 260 that includes a notification to inform the data communication unit 260 of the arrival of at least one of the maintenance period and replacement period. The data communication unit 260 transmits the notification signal to the server 400 (Figure 1) via the network 20. The server 400 receives the notification signal from the control device 200 via the network 20. Subsequently, the server 400 transmits the notification signal to the terminal device 500 via the network 20. When the terminal device 500 receives the notification signal from the server 400 via the network 20, it displays a message or outputs sound, similar to the output unit 250 of the control device 200. In other words, the server 400 causes the terminal device 500 to output the notification.

[0040] The subject of the apparatus, system, or method in this disclosure comprises a computer. The functions of the subject of the apparatus, system, or method in this disclosure are realized by the computer executing a program. The computer comprises a processor as its main hardware component, which operates according to the program. The processor is of any type as long as it can realize its functions by executing the program. The processor consists of one or more electronic circuits, including semiconductor integrated circuits (ICs) or LSIs (Large Scale Integrations). Multiple electronic circuits may be integrated on one chip or provided on multiple chips. Multiple chips may be aggregated in one device or provided on multiple devices. The program is recorded on a non-temporary recording medium such as a ROM, optical disc, or hard disk drive that is readable by the computer. The program may be pre-stored on the recording medium or supplied to the recording medium via a wide-area communication network, including the Internet.

[0041] The operation of the alarm system 1000 with the above configuration will now be explained. Figure 7 is a sequence diagram showing the notification procedure by the alarm system 1000. This shows the processing in (3-2) information viewing. The control device 200 sends a request signal to the sensor 100 (S10), and the sensor 100 sends an information signal to the control device 200 (S12). The control device 200 sends the sensor information to the server 400 (S14). The terminal device 500 sends a request signal to the server 400 (S16), and the server 400 sends the sensor information to the terminal device 500 (S18). The terminal device 500 displays the sensor information (S20).

[0042] Figure 8 is a flowchart showing the notification procedure by the control device 200. This shows the processing in (3-3) notification. If the manufacturing date or installation date reaches the notification deadline in the control unit 220 (Y in S100), the output unit 250 outputs a notification (S102). If the manufacturing date or installation date does not reach the notification deadline in the control unit 220 (N in S100), the process is terminated.

[0043] According to this embodiment, when at least one of the manufacturing date information and installation date information received from the sensor 100 reaches its notification deadline, a notification regarding at least one of the maintenance period and replacement period is output, making it easy to understand the maintenance period or replacement period. Furthermore, since a notification deadline is set, notifications can be executed at a timing that aligns with the administrator's wishes. In addition, the manufacturing date information and installation date information are also stored in the server 400, so they can be displayed on the terminal device 500. Furthermore, since the manufacturing date information and installation date information are displayed on the terminal device 500, the administrator can be sure that the maintenance period or replacement period has arrived without fail. In addition, related information is also sent to the server 400, so various information can be stored in the server 400.

[0044] Furthermore, since notifications are also sent from the terminal device 500, administrators can be sure that maintenance or replacement times are not missed. Also, if the installation date is earlier than the manufacturing date, the system will notify the system of an error in at least one of the manufacturing date or installation date, thereby improving the accuracy of the timing of notifications regarding at least one of the maintenance or replacement dates. In addition, since the control device 200 can write the installation date to the sensor 100, not only does the control device 200 know the installation date of the sensor 100, but the sensor 100 itself can also store the installation date even if only the control device 200 is replaced.

[0045] An outline of one aspect of the present disclosure is as follows: An alarm system (1000) in one aspect of the present disclosure comprises a plurality of sensors (100) and a control device (200) capable of communicating with each of the plurality of sensors (100). The control device (200) comprises a receiving unit (212) that receives from each of the plurality of sensors (100) information indicating the year and month in which the sensor (100) was manufactured and information indicating the year and month in which the sensor (100) was installed, and an output unit (250) that outputs a notification regarding at least one of the manufacturing date and installation date received by the receiving unit (212) when the notification deadline has been reached.

[0046] The control device (200) may further include a setting unit (222) for setting a notification deadline.

[0047] The control device (200) may further include a server (400) that can communicate with it. The control device (200) may further include a communication unit (260) that transmits the manufacturing date information and installation date information received by the receiving unit (212) to the server (400). The server (400) informs the terminal device (500) of the manufacturing date information and installation date information in response to a request from the terminal device (500) that can communicate with it.

[0048] The receiving unit (212) also receives relevant information related to each of the multiple sensors (100), and the communication unit (260) may also transmit the relevant information received by the receiving unit (212) to the server (400).

[0049] The communication unit (260) sends a notification to be output from the output unit (250) to the server (400), and the server (400) may have the notification output from the terminal device (500).

[0050] The output unit (250) indicates an error in at least one of the manufacturing date and installation date if the installation date is earlier than the manufacturing date.

[0051] Another aspect of the present disclosure is a control device (200).
