alarm systems, controls, detectors

TECHNICAL FIELD The present disclosure relates to notification technology, and more particularly to alarm systems, controllers, and detectors that provide information about detectors.

In the fire alarm system, a large number of fire sensors installed in the building are connected to fire receivers via sensor lines, and the fire receivers acquire fire detection information from each fire sensor through the sensor lines. When a fire occurs, the fire receiver notifies an emergency contact such as a fire department of the occurrence of the fire (fire alarm) through a public telephone line or the like. Some fire detectors have a self-diagnostic function to diagnose whether their own fire detection function is normal. and send it to the fire receiver through the detector line. The maintenance company performs maintenance based on the self-diagnosis result information. Self-diagnosis result information is also transmitted to a management device via the Internet in order to facilitate work schedule planning by a maintenance company (see, for example, Patent Document 1).

Before specifically describing the embodiments of the present disclosure, an overview of the present embodiments will be described. An embodiment relates to an alarm system including a plurality of sensors (fire detectors) installed in a facility such as a building and a controller (fire receiver) capable of communicating with each of the plurality of sensors. In the alarm system, when the detector detects the occurrence of fire, the control device executes the fire alarm. Until now, administrators have used personal computers or papers of a different medium from the alarm system when recording the operation start time and maintenance time of the alarm system, especially the date of manufacture and installation of the detector. For this reason, when the time for maintenance or replacement approaches after several months to several years have passed since the start of operation, oversights are likely to occur. In addition, the detector should be replaced 10 to 15 years after the start of use. It is difficult to grasp the replacement timing only by the month. In addition, when it becomes necessary to find a sensor that matches a specific date of manufacture due to the discovery of a problem with the quality of the sensor, the manager checks the installed sensor one by one. It has to be done, and it takes a lot of work.

The warning system in this embodiment notifies the administrator of the annual maintenance or replacement period by storing the date of manufacture and the date of installation of the sensor in the sensor and the control device. Specifically, the year and month of manufacture of the sensor are not only printed on the main body, but also stored in the storage section within the sensor. Furthermore, the control device acquires the date of manufacture from the sensor through communication. As a result, the date of manufacture can be grasped by the control device and the terminal device connected to the control device. In addition, information regarding maintenance/replacement, such as installation date and installation position, can be written from the control device to the sensor. The written installation date and installation position are transmitted from the sensor to the control device. As a result, not only does the control device grasp the date of installation of the sensor, but the date of installation is stored in the main body of the sensor even when only the control device is replaced.

Since information such as the date of manufacture and the date of installation are aggregated in the control device and server, it is possible to display the information on the control device and notify it on the terminal device. Furthermore, the control device outputs a notification regarding at least one of the maintenance timing and the replacement timing when the date of manufacture or the date of installation reaches the notification deadline. As a result, when the time for maintenance or replacement approaches, the administrator can grasp the information without omission.

FIG. 4(a) shows the data structure of the table at the time of manufacture. The table includes product number information, type information, and manufacturing date information. FIGS. 4(b)-(c) will be described later.

(2) Stages from Construction and Wiring to Start of Operation A sensor 100 is connected to each room of the facility, and each sensor 100 is connected by a sensor line 10 . Sensor line 10 is also connected to controller 200 . Control device 200 is connected to network 20 . As a result, the configuration shown in FIG. 1 is realized. In order for each sensor 100 to communicate with the control device 200 via the sensor line 10, each sensor 100 has information for identifying the sensor 100 (hereinafter referred to as "sensor address information"). is set. For setting the sensor address information, for example, DIP switches (not shown) provided in the sensor 100 are used. The storage unit 130 of the sensor 100 stores sensor address information. FIG. 4(b) shows the data structure of the table at the time of construction/wiring. In the table, sensor address information is added to the information shown in FIG. 4(a). FIG. 4(c) will be described later.

The input unit 240 of the control device 200 shown in FIG. 3 is an interface for administrators and users to input information, such as buttons and a touch panel. After installing the sensor 100 , the administrator inputs installation date information to the input unit 240 . Managers may include contractors. The installation date indicates the date when the sensor 100 was installed. The installation date may be not only the date of installation but also the date of operation of the warning system. Also, the year and month of installation may be the year in which the sensor 100 was installed. Upon receiving the installation year/month information from input unit 240 , control unit 220 outputs the installation year/month information to transmission unit 214 . The transmission unit 214 transmits installation date information to each sensor 100 via the sensor line 10 .

The receiving unit 112 of the sensor 100 shown in FIG. 2 receives installation date information via the sensor line 10 . Receiving section 112 outputs the installation date information to control section 120 . Control unit 120 writes the installation date information to storage unit 130 . FIG. 4(c) shows the data structure of the table at the time of construction and wiring subsequent to FIG. 4(b). In the table, installation year/month information is added to the information shown in FIG. 4(b). In other words, storage unit 130 stores at least manufacturing year/month information and installation year/month information.

A setting device 30 may be used to write installation date information to the sensor 100, as shown in FIG. The setting device 30 is a device for inputting settings to the sensor 100, has a cable for connecting to the sensor 100, and has an interface for an administrator to input information. With the cable inserted into the sensor 100 , the setting device 30 transmits the installation year/month information to the sensor 100 upon receiving the installation year/month information from the administrator via the interface. As before, the control unit 120 of the sensor 100 writes the installation date information to the storage unit 130 .

After the installation date information is stored in the storage unit 130 of each sensor 100, the administrator inputs the notification deadline into the input unit 240 of the control device 200 in FIG. The notification deadline is information relating to the period from the date of manufacture or the date of installation until the time of maintenance or replacement is notified, and corresponds to a threshold for the period from the date of manufacture or the date of installation. For example, the notification deadline for maintenance timing is entered every six months from the date of manufacture, and the notification deadline for replacement timing is entered to be three years from the installation date. The notification date is not limited to these, and hereinafter, the notification deadline for maintenance timing and the notification deadline for replacement timing will be collectively referred to as "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 a plurality of sensors 100 , or a notification deadline may be set for each sensor 100 .

(3) After Starting Operation (3-1) Collection of Information The control unit 220 of the control device 200 in FIG. The transmitter 214 transmits a request signal to each sensor 100 via the sensor line 10 . Transmission of the request signal may be made periodically.

The receiving section 112 of the sensor 100 in FIG. 2 receives the request signal via the sensor line 10 . Receiving section 112 outputs the request signal to control section 120 . When receiving section 112 receives the request signal, control section 120 outputs the information of the table stored in storage section 130 to transmitting section 114 as an information signal. The information signal includes, for example, sensor address information, product number information, type information, manufacturing year/month information, and installation year/month information. The transmitter 114 transmits information signals via the sensor line 10 . When receiving section 112 receives a request signal or information signal, control section 120 causes transmission section 114 to transmit the received request signal or information signal. That is, the request signal and the information signal are transferred in sequence in the multiple sensors 100 .

The receiving section 212 of the control device 200 in FIG. 3 receives information signals from each sensor 100 via the sensor line 10 . That is, the receiving unit 212 receives manufacturing year/month information and installation year/month information from each of the plurality of sensors 100 , and also receives related information related to the sensors 100 . Related information corresponds to product number information and the like. Communication unit 210 outputs the received information signal to control unit 220 . Control unit 220 stores the content of the information signal in storage unit 230 .

Identification information is assigned to the room in which the sensor 100 is installed, and the administrator inputs the identification information of the room in which the sensor 100 is installed to the input unit 240 as installation location information. Control unit 220 also stores the installation location information in storage unit 230 . 5(a) and 5(b) show the data structure of information in the control device 200. FIG. FIG. 5A shows the data structure of a table stored in the storage unit 230. FIG.

FIG. 5(b) will be described later, returning to FIG.

Here, the control unit 220 may compare the manufacturing year/month information and the installation year/month information for one sensor 100 . Since the sensor 100 is installed after being manufactured, the date of manufacture should precede the date of installation. However, if an error occurs when storing the date of manufacture or the date of installation in the storage unit 130, the date of installation will be earlier than the date of manufacture. 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 the installation date. At that time, the control unit 220 notifies the error from the output unit 250 .

(3-2) Browsing of Information Control unit 220 outputs the table stored in storage unit 230 to data communication unit 260 as sensor information. The sensor information may include a unique ID for controller 200 . Data communication unit 260 transmits sensor information to server 400 (FIG. 1) via network 20 . This corresponds to transmitting the manufacturing year/month information, the installation year/month information, and related information to the server 400 .

The server 400 in FIG. 1 can communicate with the control device 200 via the network 20 and receives sensor information from the control device 200 .

One of the application programs is an application program capable of executing processing in alarm system 1000 (hereinafter referred to as "alarm system application"). The administrator inputs a request for viewing sensor information by operating the terminal device 500 . Upon receiving the request, the terminal device 500 transmits a request signal for requesting viewing of sensor information to the server 400 via the network 20 .

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 corresponds to informing the terminal device 500 of the manufacturing date information and the 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 through the network 20, the terminal device 500 displays the sensor information on the screen. By looking at the screen, the administrator recognizes sensor address information, product number information, type information, manufacturing year/month information, installation year/month information, and installation location information for each sensor 100 .

The operation of the alarm system 1000 configured as above will be described. FIG. 7 is a sequence diagram showing a notification procedure by the alarm system 1000. As shown in FIG. This shows the processing in (3-2) viewing of information. When the control device 200 transmits a request signal to the sensor 100 (S10), the sensor 100 transmits an information signal to the control device 200 (S12). The control device 200 transmits sensor information to the server 400 (S14). When the terminal device 500 transmits a request signal to the server 400 (S16), the server 400 transmits sensor information to the terminal device 500 (S18). The terminal device 500 displays sensor information (S20).

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

According to this embodiment, when at least one of the date of manufacture and the date of installation received from the sensor 100 reaches the notification deadline, the notification regarding at least one of the maintenance time and the replacement time is output. Therefore, it is possible to easily grasp the timing of maintenance or replacement. In addition, since the notification deadline is set, the notification can be executed at the timing according to the administrator's intention. Further, since the manufacturing year/month information and the installation year/month information are also stored in the server 400 , the manufacturing year/month information and the installation year/month information can be displayed on the terminal device 500 . In addition, since the date of manufacture and the date of installation are displayed on the terminal device 500, the administrator can fully grasp the arrival of maintenance time or replacement time. In addition, since related information is also transmitted to server 400, various information can be stored in server 400. FIG.

In addition, since the terminal device 500 also notifies, the administrator can fully grasp the arrival of the maintenance time or the replacement time. Also, if the installation date is earlier than the manufacturing date, at least one of the manufacturing date and the installation date is incorrect, so the accuracy of the output timing of the notification regarding at least one of the maintenance time and the replacement time. can be improved. In addition, since the control device 200 can write the date of installation to the sensor 100, the control device 200 not only grasps the date of installation of the sensor 100, but also detects the sensor even if only the control device 200 is replaced. 100 units can memorize the date of installation.
