Description

The present invention relates to a fire alarm system and disaster prevention information management system that stores and manages history information printed by a receiver's printer.

Conventionally, in fire alarm systems that monitor for fires by connecting fire detectors to a signal line pulled out from a receiver, events that occur during the operation of the fire alarm system, such as fires, malfunctions, and inspections, are printed as history information by a printer installed in the receiver and are also stored in memory such as RAM installed in the receiver.

However, the capacity of the RAM installed in such receivers is limited. For example, the RAM becomes full with about one year's worth of history data. In such a case, the past history data stored in the RAM is printed out by a printer and stored, and the history data in the RAM is either erased or overwritten with new history data. This causes problems, such as the fact that the print data is bulky and is printed on thermal paper using an inexpensive thermal printer, and that thermal paper on which the history data is printed is not suitable for long-term storage.

The objective of the present invention is to provide a fire alarm system and disaster prevention information management system that allows historical data to be stored and used without being restricted by the memory capacity of the receiver.

[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 that is composed of a fire alarm system and a server.

The basic concept of the fire alarm system and disaster prevention information management system according to this embodiment is that the fire alarm system 10 monitors for fires by connecting a fire detector 16 to a signal line 14 drawn from a receiver 12 to a warning area, and 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 a specified event such as a fire, failure, inspection, or operation, and a print information transmission control means function for transmitting the print information output to the printer 18 to a specified server 24 via the Internet 22 for storage, and the server 24 processes the print data received from the receiver 12 into a specified viewable format and stores it as history data (history information).

As a result, print data generated by the receiver 12 based on the occurrence of events such as fires, failures, inspections, and operations is output to the printer 18 and printed as history data, and at the same time, the print data is sent to the server 24 on the Internet 22 and stored there. Even if there is a limit to the memory, such as a RAM, that stores history data in the receiver 12, it is not necessary to print and store past history data on the printer 18, and history data generated over a long period of time can be stored and used without being restricted by the storage capacity of the RAM, etc. This is explained in detail below.

[Outline of fire alarm system and disaster prevention information management system]
As shown in Fig. 1, a fire alarm system 10 is installed in a manager's room on the first floor of a building, for example, with an R-type receiver 12, and signal lines 14 are drawn from the receiver 12 to the alert area, divided into different systems, to which multiple analog fire detectors 16 with transmission functions and unique addresses are connected to monitor for fires. Note that on-off type fire detectors and transmitters are connected to the detector lines drawn from repeaters with transmission functions and unique addresses on the signal lines 14, and smoke control and exhaust equipment, etc. are also connected via the repeaters, but are not shown in the figure.

The receiver 12 is also provided with a printer 18, and when an event such as a fire, failure, inspection, or operation occurs on the receiver 12, specific print data is generated based on this and output to the printer 18 to be printed as history data.

The receiver 12 is also provided with a gateway device 20, allowing it to communicate with a server 24 via the Internet 22.

The receiver 12 generates print data based on the occurrence of a specified event such as a fire, failure, inspection, or operation, and when outputting the data to the printer 18 for printing, branches the print data to the gateway device 20, and transmits the data from the gateway device 20 to the server 24 via the Internet 22.

The server 24, which receives the print data from the receiver 12, processes the received print data into a predetermined viewable format and stores it as history data. The history data of the fire alarm system 10 stored on the server 24 can be searched and viewed by the client 28, the receiver 12, and the disaster prevention display panel 15 connected via the LAN line 26. In addition, the history data can be searched and viewed from a mobile terminal 34 such as a smartphone or tablet via a mobile phone substation 32 of the mobile phone network 30.

[Functional configuration of receiver and server]
FIG. 2 is a block diagram showing the functional configuration of the receiver and the server, FIG. 3 is an explanatory diagram showing the external appearance of the receiver from the front, and FIG. 4 is an explanatory diagram showing print data, print records, and history data.

(Receiver Functions)
As shown in FIG. 1, the receiver 12 is composed of a computer circuit having a CPU, memory, various input/output ports, etc., and is provided with a main CPU 36 and multiple sub-CPU boards 38, each of which is provided with a sub-CPU 40 and a transmission unit 42.

The main CPU 36 and the sub-CPU 40 are connected by a serial transfer bus 44 and send and receive data between them.

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

The main CPU 36 is also connected to a display 46 with a touch panel using a liquid crystal display panel or the like, a display unit 48 using indicator 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 district sound pause switch, an audio alarm unit 52 provided with a speaker, and a reporting unit 54.

The main CPU 36 is also connected to the disaster prevention display panel 15 via a serial transmission unit 45. The disaster prevention display panel 15 not only displays events that occur on the receiver 12, issues warnings, and performs operations, but also allows the viewing of historical information on the receiver 12 stored on the server 24.

The main CPU 36 is also provided with a reception control unit 56 and a print information transmission control unit 58 that function as control means by executing a program, and also with a history storage unit 60 that uses a RAM or the like.

(Appearance of the receiver)
3, a display 46 with a touch panel is disposed on the face of the receiver 12. The display 46 displays color images on its screen, and the touch panel disposed on the screen allows selection and input by touching the screen.

A guide switch 72 is located below the display 46 in the center of the left and right sides of the panel, in a position that is easy for the user to see and operate. When the guide switch 72 is operated when a fire event occurs and information that is the subject of guidance is displayed on the display 46, the guidance content is output by voice.

Furthermore, a fire determination switch 78, a main sound stop switch 74, and a district sound pause switch 76 are arranged on the panel below the display 46. A small door 82 is provided on the panel below the guide switch 72 so that it can be freely opened from the front with its lower side as an axis, and various operation switches including a recovery switch are provided on the inside of the small door 82.

In addition, a telephone microphone 80 is located on the outside of the fire termination switch 78, and in combination with a speaker inside an audio hole 84 provided next to the display 46, a hands-free emergency telephone function is realized.

The upper panel of the display 46 is provided with a fire indicator light 86 and a gas leak indicator light 88. A printer 18 is also provided below the panel of the receiver 12, and is used to print out print data based on events that occur on the receiver 12.

(Fire monitoring and control of receiver)
The sub-CPU 40 of the sub-CPU board 38 provided in the receiver 12 shown in Figure 2 performs fire monitoring control by instructing the transmission unit 42 to send and receive signals with the fire detector 16 in accordance with a specified communication protocol.

During normal monitoring, the fire monitoring control by the sub-CPU 40 periodically instructs the transmission unit 42 to transmit a broadcast batch AD conversion signal including a batch AD conversion command, and the fire detector 16 that receives this batch AD conversion signal detects and retains the smoke concentration or temperature as sensor data. Next, the sub-CPU 40 transmits a call signal including a polling command that sequentially specifies the terminal addresses.

When the fire detector 16 receives a call signal with an address that matches its own address, it transmits a response signal including the sensor data it is holding at that time to the transmission unit 42. In addition, when the smoke concentration or temperature of the fire detector 16 exceeds a predetermined fire warning level, it transmits a fire interrupt signal to the transmission unit 42 of the receiver 12.

When the sub-CPU 40 receives a fire interrupt signal via the transmission unit 42, it transmits a group search command signal to identify the group that includes the fire detector 16 that has detected the fire, then transmits an intra-group search command signal to identify the address of the fire detector 16 that has detected the fire, collects analog sensor data in a centralized manner, and transmits the data to the main CPU 36 via the serial transfer bus 44.

The main CPU 36 compares the analog data received from the sub-CPU 40 with a predetermined fire determination level, and when the analog data reaches the fire determination level, it determines that there is a fire, turns on the fire representative light 86 on the display unit 48, outputs a predetermined main sound alarm indicating the occurrence of a fire from the speaker of the sound alarm unit 52, displays fire alarm information including the location of the fire based on the address of the sensor where the fire was detected on the display 46, and further outputs a fire alarm signal to the outside via the alarm transmission unit 54 to perform predetermined alarm transmission control, etc.

(Receiver print information transmission control)
The print information transmission control unit 58, which functions as a print information transmission control means provided in the main CPU 36 of the receiver 12 shown in FIG. 2, outputs the print data to the printer 18 to be printed out when print data is generated by the receiving control unit 56 based on the occurrence of an event such as a fire, failure, inspection, or operation, and also controls the printing data to be branched and output to the gateway device 20, so that the gateway device 20 transmits the print data to the server 24 via the Internet 22 in accordance with a predetermined Internet protocol.

The print data is sent as a serial signal to the printer 18 and the gateway device 20, and the characters in the print data received by the server 24 are in a format that can be recognized as characters rather than as an image.

The reception control unit 56 generates print data 90 in the format shown in FIG. 4(A) based on the occurrence of an event. In this embodiment, the print data 90 is composed of date and time, location, type, and content. FIG. 4(B) shows a print result 92 of the print data 90 generated by the reception control unit 56 when a fire breaks out, in which, for example, the time flow goes from bottom to top, and the date "2019/02/01" is printed at midnight, after which the print data associated with the occurrence of the fire is printed.

For example, looking at the first stamp data, the location "1st floor south area" is printed after the time, minute, and second "023425", then "analog smoke" is printed as the type, indicating that it is an analog smoke detector, and finally "alarm" is printed as the content. In addition, the print data printed out by printer 18 is simultaneously stored in history storage unit 60, which uses RAM or the like, but the storage capacity of history storage unit 60 is limited, and when the storage capacity runs out, old history data is overwritten and stored, so that only history data for a limited period of time, such as one year's worth, is stored.

The type and content of the print data 90 can be any appropriate content and format required as a history. In addition to branching the print data to the gateway device 20 in real time and transmitting it to the server 24, the print information transmission control unit 58 can also temporarily store the print data in a buffer memory for transmission, read it out from the buffer memory at predetermined intervals, for example, at daily intervals, output it to the gateway device 20, and transmit it to the server 24.

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

When the server control unit 64 receives print data transmitted by the receiver 12 via the communication control unit 62, it generates history data 94 in the format shown in FIG. 4(C), for example, and stores it in the memory unit 70. The history data 94 in FIG. 4(C) combines predetermined search data 96 with the beginning of the print data 90 received from the receiver 12, and the search data 96 is, for example, date data. By specifying a date, the user can extract and view the history data for the specified date from the history data 94 stored in the memory unit 70.

In addition, when the server control unit 64 stores historical data for multiple fire alarm systems 10 in the memory unit 70, the server control unit 64 stores the system ID assigned to the fire alarm system in addition to the date in the search data 96, thereby enabling viewing by searching the historical data 94 specifying the fire alarm system.

The history data 94 stored on the server 24 can be viewed from the client 28, mobile terminal 34, receiver 12, and disaster prevention display panel 15.

When the server control unit 64 stores the history data 94 in the storage unit 70, the print data 90 may be converted to predetermined image data, such as PDF format, that can be displayed on a display while maintaining a form in which the client 28, the mobile terminal 34, or the disaster prevention display board 15 can recognize characters as characters, and then stored. By converting the print data 90 into image data and storing it in this way, conversion from the print data 90 to image data is not required when viewing the history data 94 from the client 28, the receiver 12, the disaster prevention display board 15, the mobile terminal 34, etc., and the use of the history data 94 is made more efficient. In addition, the use of the history data 94 can be made even more efficient by using the specific information of the terminal and time information contained in the history data as a search target for character information.

[Modifications of the present invention]
(Disaster prevention display board)
In addition to the above embodiment, when a user selects historical data, the disaster prevention display panel 15 may identify the terminal related to the selected history based on the terminal identification information included in the historical data 94, and highlight the terminal on the map displayed on the disaster prevention display panel 15.

(Print data)
In the above embodiment, print data is generated based on the occurrence of an event such as the activation of a fire detector, but the generated print data is not limited to this. Receiver setting information and the like may be sent to the server 24 as print data. At this time, printing from the printer 18 may not be performed. Also, in order to distinguish whether printing has been performed from the printer 18, the print data may include information that distinguishes whether the data is to be printed by the printer.

(Viewing and printing print data using the receiver)
In the above embodiment, the history data 94 can be viewed on the receiver 12, but it may also be possible to print it.

(Printing by clients and disaster prevention display boards)
In the above embodiment, the history data 94 can be viewed on the client 28 or the disaster prevention display panel 15, but it may be printed. By making it possible to print on the client 28 or the disaster prevention display panel 15, it becomes possible to print on A4 paper or the like using a high-performance printer. Therefore, it becomes possible to print the history data 94 and attach it to a report on an inspection or the like.

(P-type receiver)
The above embodiment takes as an example a fire alarm system in which an R-type fire detector is connected via a signal line from an R-type receiver, but the same can also be applied to a P-type fire alarm system 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.

(Receiver without printer)
In the above embodiment, the receiver is provided with a printer to print out the print data, but the receiver may not be provided with a printer as long as it has a function to output print data.
