Mode for Carrying Out the Invention

[0011] [Fire Alarm Equipment and Disaster Prevention Information Management System] (Basic Concept of the Embodiment) FIG. 1 is an explanatory diagram showing an overview of a disaster prevention information management system composed of a fire alarm device and a server.

[0012] The basic concept of the fire alarm equipment and the disaster prevention information management system according to this embodiment is that the fire alarm equipment 10 monitors for fires by connecting a fire detector 16 to a signal line 14 led out from the receiver 12 to a warning area. The receiver 12 is provided with a printer 18 that functions as a printing means for printing print data (print information) based on the occurrence of predetermined events such as fires, failures, inspections, and operations, and a function of print information transmission control means for transmitting the print information output to the printer 18 to a predetermined server 24 via the Internet 22 for storage. The server 24 processes the print data received from the receiver 12 into a predetermined format that can be browsed and stores it as history data (history information).

[0013] Therefore, the print data based on the occurrence of events such as fires, failures, inspections, and operations generated by the receiver 12 is output to the printer 18 and printed as history data. At the same time, the print data is transmitted to and stored in the server 24 on the Internet 22. Even if there are limitations in the memory such as RAM for storing history data in the receiver 12, it is not necessary to print and store the past history data with the printer 18, and the history data generated over a long period can be stored and used without being restricted by the storage capacity of the RAM or the like. This will be described in detail below.

[0014] [Overview of Fire Alarm Equipment and Disaster Prevention Information Management System] As shown in FIG. 1, for the fire alarm equipment 10, for example, an R-type receiver 12 is installed in the building manager's office on the first floor. Signal lines 14 are drawn out from the receiver 12 for each system to the warning areas, and a plurality of analog fire detectors 16 with a transmission function having a unique address are connected to monitor for fires. In addition, on the signal line 14, an on-off type fire detector and a transmitter are connected to the detector line drawn from a repeater having a transmission function with a unique address set, and smoke control equipment etc. is connected via the repeater, but the illustration is omitted.

[0015] In addition, a printer 18 is provided in the receiver 12. When events such as fires, malfunctions, inspections, and operations occur in the receiver 12, predetermined print data is generated based on this, output to the printer 18, and printed as history data.

[0016] Also, a gateway device 20 is provided in the receiver 12 so that it can be communicatively connected to the server 24 via the Internet 22.

[0017] When the receiver 12 generates print data based on the occurrence of predetermined events such as fires, malfunctions, inspections, and operations, outputs it to the printer 18 for printing, the print data is branched to the gateway device 20, and transmitted from the gateway device 20 to the server 24 via the Internet 22.

[0018] The server 24 that has received the print data from the receiver 12 processes the received print data into a predetermined form that can be browsed and stores it as history data. The history data of the fire alarm equipment 10 stored in the server 24 can be searched and browsed by the client 28, the receiver 12, and the disaster prevention display panel 15 connected via the LAN line 26. Also, the necessary history data can be searched and browsed from a mobile terminal 34 such as a smartphone or a tablet via the mobile phone slave station 32 of the mobile phone network 30.

[0019] [Functional Configuration of Receiver and Server] FIG. 2 is a block diagram showing the functional configurations of the receiver and the server, FIG. 3 is an explanatory diagram showing the front view of the receiver, and FIG. 4 is an explanatory diagram showing print data, print records, and history data.

[0020] (Function of the Receiver) As shown in FIG. 1, the receiver 12 is composed of a computer circuit including a CPU, a memory, various input / output ports, etc. A main CPU 36 and a plurality of sub-CPU boards 38 are provided, and a sub-CPU 40 and a transmission unit 42 are provided on the sub-CPU board 38.

[0021] The main CPU 36 and the sub-CPU 40 are connected by a serial transfer bus 44 and transmit and receive data to and from each other.

[0022] A printer 18 is connected to the main CPU 36, and a gateway device 20 that branches print data for the printer 18 and transmits it to the server 24 is connected.

[0023] In addition, the main CPU 36 is provided with a display 46 with a touch panel using a liquid crystal display panel or the like, a display unit 48 using display lights such as LEDs, an operation unit 50 provided with various switches such as a fire determination switch, a main sound stop switch, and a local sound temporary stop switch, a sound alarm unit 52 provided with a speaker, and a transfer unit 54.

[0024] In addition, a disaster prevention display board 15 is connected to the main CPU 36 via a serial transmission unit 45. The disaster prevention display board 15 enables display, alarm, and operation of events generated by the receiver 12, and also enables browsing of the history information of the receiver 12 stored in the server 24.

[0025] In addition, a reception control unit 56 and a print information transmission control unit 58 that function as control means by executing a program are provided in the main CPU 36, and a history storage unit 60 using a RAM or the like is provided.

[0026] (Appearance of the Receiver) As shown in FIG. 3, a display 46 with a touch panel is arranged on the front panel of the receiver 12. The display 46 displays a color image on the screen, and by arranging the touch panel on the screen, selection and input by screen touch operation are enabled.

[0027] A guide switch 72 is arranged at a position that is easy to see and operate for the user, which is at the center of the left and right sides of the front panel below the display 46. When the guide switch 72 is operated when information to be guided is displayed on the display 46 due to a fire event, the guidance content is output by voice.

[0028] Also, a fire determination switch 78, a main sound stop switch 74, and a district sound temporary stop switch 76 are arranged on the front panel below the display 46. A small door 82 is provided on the front panel below the guide switch 72 so as to be able to open forward with the lower side as the axis, and various operation switches including a recovery switch are provided inside the small door 82.

[0029] Also, a telephone microphone 80 is arranged outside the fire determination switch 78, and in combination with a speaker inside an acoustic hole 84 provided beside the display 46, a hands-free emergency telephone function is realized.

[0030] Also, a fire indicator lamp 86 and a gas leakage indicator lamp 88 are provided on the front panel above the display 46. Further, a printer 18 is arranged below the front panel of the receiver 12, and print data based on events occurring in the receiver 12 is printed and output.

[0031] (Fire monitoring control of the receiver) The sub-CPU 40 of the sub-CPU board 38 provided in the receiver 12 shown in FIG. 2 performs fire monitoring control by instructing the transmission unit 42 to transmit and receive signals with the fire detector 16 according to a predetermined communication protocol.

[0032] During normal monitoring, the sub-CPU 40 instructs the transmission unit 42 at regular intervals to send a broadcast batch AD conversion signal including a batch AD conversion command. The fire detector 16 that receives this batch AD conversion signal detects and holds the smoke density or temperature as sensor data. Subsequently, the sub-CPU 40 sends a call signal including a polling command with the terminal address specified sequentially.

[0033] When the fire detector 16 receives a call signal with an address that matches its own address, it sends a response signal including the sensor data held at that time to the transmission unit 42. Also, when the smoke density or temperature exceeds a predetermined fire warning level, the fire detector 16 sends a fire interrupt signal to the transmission unit 42 of the receiver 12.

[0034] When the sub-CPU 40 receives a fire interrupt signal via the transmission unit 42, it sends a group search command signal to identify the group including the fire detector 16 that detected the fire. Subsequently, it sends a search command signal within the group to identify the address of the fire detector 16 that detected the fire and intensively collect the analog data of the sensor, and sends it to the main CPU 36 via the serial transfer bus 44.

[0035] The main CPU 36 compares the analog data received from the sub-CPU 40 with a predetermined fire determination level. When the analog data reaches the fire determination level, it determines that there is a fire, lights the fire indicator lamp 86 of the display unit 48, outputs a predetermined main acoustic alarm indicating the occurrence of a fire from the speaker of the acoustic alarm unit 52, displays fire alarm information including the location of the fire based on the address of the detector where the fire was detected on the display 46, and further outputs a fire transfer signal to the outside by the transfer unit 54 to perform predetermined transfer control and the like.

[0036] (Printing Information Transmission Control of Receiver) The print information transmission control unit 58, which functions as print information transmission control means provided in the main CPU 36 of the receiver 12 shown in FIG. 2, when print data is generated based on the occurrence of events such as fire, failure, inspection, operation, etc. by the reception control unit 56, outputs the print data to the printer 18 for printing output, and also performs control to branch the print data and output it to the gateway device 20. As a result, the gateway device 20 transmits the print data to the server 24 via the Internet 22 according to a predetermined Internet protocol.

[0037] The print data is transmitted as a serial signal to the printer 18 and the gateway device 20, and the characters of the print data received by the server 24 are in a form that can be recognized as characters rather than images.

[0038] The reception control unit 56 generates print data 90 in the format shown in FIG. 4(A) based on the occurrence of an event. The print data 90 of the present embodiment is composed of date and time, location, type, and content. FIG. 4(B) is the print result 92 of the print data 90 generated when a fire occurs in the reception control unit 56. For example, it is the flow of time from bottom to top, and the date "2019 / 02 / 01" is printed at the timing of midnight, and then the print data associated with the fire occurrence is printed.

[0039] For example, looking at the first print data, "1st floor south area" is printed following the time "02:34:25", then "Analog Smoke" indicating an analog smoke detector is printed as the type, and finally "Alarm" is printed as the content. Also, the print data printed out by the printer 18 is simultaneously stored in the history storage unit 60 using a RAM or the like, but there is a limit to the storage capacity of the history storage unit 60. When the storage capacity runs out, it overwrites and stores the old history data, and only history data for a limited period, such as one year, is stored.

[0040] Note that the format and content of the print data 90 can be appropriate content and format required as a history. Further, in addition to branching the print data in real time to the gateway device 20 and transmitting it to the server 24, the print information transmission control unit 58 may temporarily store the print data in a buffer memory for transmission, read it from the buffer memory in units of a predetermined period, for example, in units of one day, output it to the gateway device 20, and transmit it to the server 24.

[0041] (Server) As shown in FIG. 2, the server 24 is composed of a computer circuit including a CPU, a memory, various input / output ports, etc., and includes a communication control unit 62, a server control unit 64, an operation unit 66 such as a keyboard and a mouse, a display unit 68 using a display, and a storage unit 70 having a sufficient storage capacity.

[0042] When the server control unit 64 receives the print data transmitted by the receiver 12 via the communication control unit 62, for example, it generates history data 94 in the format shown in FIG. 4(C) and stores it in the storage unit 70. The history data 94 in FIG. 4(C) combines predetermined search data 96 at the head of the print data 90 received from the receiver 12. As the search data 96, for example, date data is used, and the user can specify the date and extract and view the history data of the specified date from the history data 94 stored in the storage unit 70.

[0043] Further, when the server control unit 64 stores the history data of a plurality of fire alarm facilities 10 in the storage unit 70, by storing the facility ID assigned to the fire alarm facility in addition to the date in the search data 96, browsing by searching the history data 94 specifying the fire alarm facility is enabled.

[0044] The browsing of the history data 94 stored in the server 24 can be performed not only from the client 28 and the mobile terminal 34 but also from the receiver 12 and the disaster prevention display panel 15.

[0045] Incidentally, when the server control unit 64 stores the history data 94 in the storage unit 70, the print data 90 may be converted into predetermined image data that can be displayed on the display while maintaining a form in which the client 28, the mobile terminal 34, and the disaster prevention display panel 15 can recognize the characters as characters, for example, in PDF format and stored. By converting and storing the print data 90 as image data in this way, when browsing the history data 94 from the client 28, the receiver 12, the disaster prevention display panel 15, the mobile terminal 34, etc., conversion from the print data 90 to the image data becomes unnecessary, and the use of the history data 94 is made more efficient. In addition, it becomes possible to further improve the efficiency of using the history data 94 by utilizing the terminal specific information and time information included in the history data with the character information as the search target.

[0046] [Modification Example of the Present Invention] (Disaster Prevention Display Panel) In addition to the above-described embodiment, when the user selects the history data, the disaster prevention display panel 15 may specify the terminal related to the selected history based on the terminal specific information included in the history data 94, and highlight the terminal on the map displayed on the disaster prevention display panel 15.

[0047] (Print Data) In the above-described embodiment, the print data is generated based on the occurrence of an event such as the alarm of the fire detector, but the generated print data is not limited to this. The setting information of the receiver etc. may be transmitted to the server 24 as print data. At this time, printing from the printer 18 may not be performed. Further, in order to distinguish whether printing has been performed from the printer 18, information for distinguishing whether the print data is a printing target by the printer may be included in the print data.

[0048] (Viewing / Printing of Print Data by Receiver) In the above-described embodiment, the history data 94 can be viewed by the receiver 12, but it may be made printable.

[0049] (Printing by Client or Disaster Prevention Display Panel) In the above-described embodiment, the history data 94 can be viewed on the client 28 or the disaster prevention display board 15, but it may also be made printable. By enabling printing on the client 28 or the disaster prevention display board 15, printing on A4 paper or the like becomes possible with a high-function printer. Therefore, it becomes possible to print the history data 94 and attach it to a report for inspection or the like.

[0050] (P-type receiver) The above-described embodiment takes as an example the fire alarm equipment in which an R-type fire detector is connected via a signal line from an R-type receiver. However, the present invention can be similarly applied to P-type fire alarm equipment in which an on-off type fire detector is connected to a detector line drawn from a P-type receiver that monitors fires on a line-by-line basis.

[0051] (Receiver without printer) Also, in the above-described embodiment, a printer is provided in the receiver to print and output print data. However, any device having a function of outputting print data may be used, and a receiver without a printer may also be used.

[0052] (Others) Furthermore, the present invention includes appropriate modifications that do not impair its object and advantages, and is not limited by the numerical values shown in the above-described embodiment.
