Mode for Carrying Out the Invention

[0015] Hereinafter, an embodiment of the disaster prevention monitoring system according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by the following embodiments.

[0016] [Basic Concept of the Embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a disaster prevention monitoring system that monitors and operates fire notification equipment installed in a building from a processing device at a remote site away from the building.

[0017] Here, the "fire notification equipment" of the building is equipped with a fire receiver that connects a plurality of fire detectors to monitor for fires.

[0018] In the embodiment, in addition to the fire notification equipment composed of a fire detector and a fire receiver, a fire monitoring computer and an IP-KVM switch are provided in the building.

[0019] The "fire monitoring computer" generates screen information related to fire monitoring based on the fire information signal output by the fire receiver, transmits the screen information signal, and receives an operation information signal from the outside.

[0020] In addition, the "fire monitoring computer" includes a computer main body, a monitor device such as a display, and an operation device such as a keyboard and a mouse.

[0021] In addition, the "screen information related to fire monitoring" generated by the fire monitoring computer is optional, but for example, it includes fire alarm information indicating the location and time of fire occurrence in a building, a floor plan of the floor where a fire breaks out and can be switched, and a floor plan of the building above and below, etc.

[0022] In addition, the "IP-KVM switch" is to IP-ify (Internet-protocol-ify) each signal of a keyboard, video, and mouse, that is, to convert it into a packet signal according to Internet protocol (TCP / IP conversion), so that it is possible to access and control various devices such as computers and servers via networks such as LAN and the Internet.

[0023] The "IP-KVM switch" in the embodiment converts the screen information signal received from the fire monitoring computer via a video cable into a screen information packet signal and transmits it to the communication network, and at the same time, converts the operation information packet signal received from the communication network into an operation information signal and transmits it to the fire monitoring computer via an operation cable.

[0024] In addition, the "remote site" is a facility such as a monitoring center installed in another building far away from the building, which means a place where a monitor can be stationed to remotely monitor and operate the fire notification equipment in the building.

[0025] The "remote site" in the embodiment is provided with a processing device for the remote site, a monitor device, and an operation device. Here, the "processing device for the remote site" is a device connected to the IP-KVM switch via a communication network. For example, a computer is used.

[0026] In addition, the "monitor device" is a display device connected to the processing device for the remote site via a video cable. The "operation device" is a device connected to the processing device for the remote site via an operation cable and includes a keyboard, a mouse, etc.

[0027] The "fire monitoring computer" of the embodiment transmits the generated screen information to a monitor device via an IP-KVM switch, a communication network, and a processing device for a remote site to display the screen information.

[0028] In addition, the "processing device for a remote site" of the embodiment enables the operation of the fire monitoring computer with the operation device by transmitting an operation information signal received from the operation device to the fire monitoring computer via a communication network and an IP-KVM switch.

[0029] Here, the fire monitoring computer as viewed from the IP-KVM switch becomes the server side of the client-server system, and the processing device for a remote site becomes the client side, and it is in a form where the server side is remotely monitored and operated from the client side.

[0030] Therefore, due to the provision of the "IP-KVM switch" for the monitoring and operation of the building's fire notification equipment by a remote site, the fire monitoring computer cannot be directly specified from the outside at the network layer and is separated from the communication network, so it is possible to reliably defend against threats from malicious attacks from the communication network.

[0031] In addition, due to the provision of the "IP-KVM switch", the screen information signal of the fire monitoring computer is IPized and the screen information is displayed at a remote site via a communication network, enabling remote operation of the fire monitoring computer with an operation device at the remote site.

[0032] The "communication network" connecting the building side and the remote site side is arbitrary and includes the Internet known as a public communication network, wireless communication networks such as G3, LET, G4, and WiFi (registered trademark).

[0033] In addition, there are a plurality of "buildings", and a fire receiver, a fire monitoring computer, and an IP-KVM switch are provided for each building.

[0034] In this case, the "processing device for remote bases" can simultaneously display on the monitor device the screens based on the plurality of screen information received from a plurality of different fire monitoring computers. Further, the "processing device for remote bases" enables the monitor device to enlarge and display the screen based on the screen information received from the fire monitoring computer of the selected fire incident building when the monitor operator selects and operates the fire incident building using the operation device.

[0035] Furthermore, the "processing device for remote bases" enables operations on the fire monitoring computer of the fire incident building selected by the operation device using the operation device.

[0036] Therefore, on the monitor device connected to the processing device for remote bases, the screens of the fire monitoring computers of a plurality of buildings (properties) are displayed as, for example, reduced screens, enabling a general understanding of the fire monitoring status of all the buildings (properties) being monitored.

[0037] Also, when the monitor operator selects and operates a fire incident building with respect to the processing device for remote bases, the fire screen is enlarged and displayed among the plurality of reduced screens displayed on the monitor device of the processing device for remote bases, enabling an appropriate understanding of the fire occurrence situation and enabling prompt execution of the necessary fire response operations using the operation device.

[0038] When the monitor operator selects and operates a fire incident building using the operation device, the screen based on the screen information received from the fire monitoring computer of the selected fire incident building is enlarged and displayed on the monitor device. Also, operations using the operation device become possible on the fire monitoring computer of the selected fire incident building.

[0039] Therefore, on the monitor device at the remote base, all of the screen information transmitted from the fire monitoring computers of a plurality of buildings is displayed as, for example, a reduced multi-screen, enabling a general understanding of the fire monitoring status of all the buildings being monitored.

[0040] In addition, with the selection operation of the fire-affected property, the operator at the remote site can operate the fire monitoring computer of the fire-affected property using the operation device at the remote site. As a result, the monitor at the remote site can perform screen operations necessary for fire response, such as switching between the building floor plans of the upper and lower floors, by operating the operation device, and can confirm the information necessary for evacuation guidance.

[0041] Hereinafter, specific embodiments will be described. In the specific embodiments shown below, a case will be described where the "communication network" is the "Internet", the "processing device for remote site" is the "processing device", and the "operation device" is the "keyboard or mouse".

[0043] [a. Configuration of Disaster Prevention Monitoring System] The configuration of the disaster prevention monitoring system will be described. In this description, refer to FIG. 1 showing a disaster prevention monitoring system for monitoring and operating the fire notification equipment of a building from a remote site.

[0044] As shown in FIG. 1, the disaster prevention monitoring system of the embodiment is composed of a building 10 to be monitored and a remote site 12.

[0045] In building 10, there are provided a fire receiver 14, a fire monitoring computer 18, an IP-KVM switch 28, and a VPN router 30.

[0046] The fire receiver 14 and the fire monitoring computer 18 constitute a fire notification facility. The fire receiver 14 is installed in the manager's room or the monitoring center of building 10, and a plurality of fire detectors 16 are connected to a detector line 15 laid in the building from the fire receiver 14.

[0047] There are R-type and P-type fire notification facilities. The embodiment is an R-type fire notification facility. A plurality of analog fire detectors 16 having a transmission function and set with addresses are connected via a transmission line 15. When a fire is detected, a fire alarm signal is transmitted to the fire receiver 14. The fire receiver 14 recognizes the fire occurrence location from the address of the fire detector 16 that detected the fire and issues a fire alarm, and the fire information is displayed on the receiver screen 1410. Also, a fire transmitter having a transmission function and address setting is connected to the transmission line 15.

[0048] The fire notification facility of the embodiment may be a P-type fire notification facility. In the P-type fire notification facility, a plurality of on-off type fire detectors 16 are connected to a signal line laid for each area from the fire receiver 14. When the fire detector 16 detects a fire and turns on, an alarm current is passed through the signal line and a fire alarm signal is transmitted to the fire receiver 14. The fire receiver 14 receives the fire alarm signal, recognizes the alarm area from the signal line, issues a fire alarm, and displays the fire information on the receiver screen 1410.

[0049] The fire monitoring computer 18 is connected to the fire receiver 14 via a transmission cable 20 such as RS232. When the fire receiver 14 detects a fire and gives an alarm, it outputs a fire alarm signal to the fire monitoring computer 18 via the transmission cable 20. The fire information signal output by the fire receiver 14 includes receiver identification information, fire occurrence area information, fire occurrence time, etc.

[0050] The fire monitoring computer 18 is connected to a monitor device 1810, a keyboard 1812, and a mouse 1814. The fire monitoring computer 18 performs screen display and operation reception as software operations. The fire monitoring computer 18 generates screen information related to fire monitoring based on the fire information signal output by the fire receiver 14 and displays it on the monitor device 1810.

[0051] In addition, the fire monitoring computer 18 receives screen operations of the monitor device 1810 by the keyboard 1812 or the mouse 1814. Furthermore, the fire monitoring computer 18 can receive an operation information signal from the outside via the IP-KVM switch 28 and perform screen operations.

[0052] The screen information associated with the fire alarm generated by the fire monitoring computer 18 is arbitrary. For example, as a fire alarm-related menu, there is floor plan information of the building 10. The floor plan information includes the floor directly above, the shipping floor, the floor directly below, other fire floors, a list of the floors where the alarm is issued, the next floor where the alarm will be issued, etc., and can be switched and displayed by screen operations. Also, as an operation menu, functions such as sound stop and receiver control are provided, enabling operation of the fire receiver 12.

[0053] Following the fire monitoring computer 18, an IP-KVM switch 28 is provided. The IP-KVM switch 28 is connected to the fire monitoring computer 18 by a video cable 22 and operation cables 24, 26.

[0054] Also, the IP-KVM switch 28 is connected to the VPN router 30 by a LAN cable 32, and the VPN router 30 is connected to the Internet 34. Here, as is well known, the VPN router 30 constructs an encrypted virtual private network on the Internet 34 to ensure secure communication. When the VPN router 30 is used, the Internet 34 can be called a virtual Internet.

[0055] The IP-KVM switch 28 receives the screen information signal of the screen displayed on the monitor 1810 from the fire monitoring computer 18 via the video cable 22, converts it into an IP packet signal (screen information packet signal) in a data format that can communicate according to a communication standard such as Ethernet (registered trademark), encrypts it with the VPN router 30, and transmits it to the Internet 34.

[0056] Also, the IP-KVM switch 28 converts the operation information packet signal of a mouse, keyboard, etc. received from the Internet 34 via the VPN router 30 into an operation information signal, and transmits it to the fire monitoring computer 18 via the operation cable 24.

[0057] On the other hand, a VPN router 36 and a processing device 40 are provided at a remote site 12 far from the building 10. The processing device 40 functions as a console of the IP-KVM switch 28. The processing device 40 includes a monitor device 42, a keyboard 44 and a mouse 46 serving as operation devices. The monitor device 42 is connected by a video cable 41, the keyboard 44 is connected by an operation cable 48, and the mouse 46 is connected by an operation cable 50. Also, the processing device 40 is connected to the Internet 34 via the VPN router 36 by a LAN cable 38.

[0058] In the disaster prevention monitoring system of FIG. 1, a screen information signal based on the screen information generated by the fire monitoring computer 18 in the building 10 is transmitted to the monitor device 42 via the IP-KVM switch 28, the VPN router 30, the Internet 34, the VPN router 36 and the processing device 40 to display the screen information.

[0059] The processing device 40 transmits an operation information signal from the operation devices of the keyboard 44 or the mouse 46 to the fire monitoring computer 18 via the VPN router 36, the Internet 34, the VPN router 30, and the IP-KVM switch 28, enabling the operation of the fire monitoring computer 18 by the operation devices of the keyboard 44 or the mouse 46 of the processing device 40.

[0060] [b. Communication Connection via IP-KVM Switch] Next, the communication connection via the IP-KVM switch will be described. In this description, refer to FIG. 2 showing the functional configurations of the fire monitoring computer, the IP-KVM switch, and the processing device for the remote site.

[0061] As shown in FIG. 2, the fire monitoring computer 18 includes a control unit 1820, a transmission I / F 1822, a monitor I / F 1824, a keyboard I / F 1826, and a mouse I / F 1828.

[0062] The control unit 1820 is a computer circuit including a CPU, a memory, an HDD, and various input / output ports. The control unit 1820 includes an OS and also has software functions for performing fire monitoring control.

[0063] The IP-KVM switch 28 includes a control unit 2810, a memory 2812, a communication I / F 2814 on the fire monitoring computer 18 side, and a communication I / F 2816 on the communication network side.

[0064] Connected to the communication I / F 2814 are a video cable 22 from the fire monitoring computer 18, an operation cable 24 for the keyboard, and an operation cable 26 for the mouse. Stored in the memory 2812 is a control program for controlling the operation of the control unit 2810.

[0065] The processing device 40 for the remote site includes a control unit 4010, a communication I / F 4012, a monitor I / F 4014, a keyboard I / F 4016, and a mouse I / F 4018.

[0066] The control unit 4010 is a computer circuit including a CPU, a memory, an HDD, and various input / output ports. The control unit 4010 includes an OS and also has software functions for performing monitoring and operation at the remote site.

[0067] The operation for communicating the screen information signal from the fire monitoring computer 18 to the processing device 40 is as follows.

[0068] The control unit 1820 of the fire monitoring computer 18 reads the screen information stored in the memory and transmits a screen information signal to the communication I / F 2814 of the IP-KVM switch 28 via the monitor I / F 1824.

[0069] The control unit 2810 of the IP-KVM switch 28 converts the screen information signal into a screen information packet signal and transmits it to the communication I / F 2816. The communication I / F 2816 transmits the screen information packet signal to the communication I / F 4012 of the processing device 40 via the VPN router 30, the Internet 34, and the VPN router 36.

[0070] The control unit 4010 of the processing device 40 acquires the screen information from the received screen information packet signal and transmits the acquired screen information to the monitor I / F 4014. The monitor I / F 4014 transmits the screen information to the monitor device 42 to end the process, and the screen information is displayed on the monitor device 42.

[0071] Also, the operation for communicating an operation information signal from the processing device 40 at the remote site to the fire monitoring computer 18 is as follows.

[0072] When the control unit 4010 of the processing device 40 receives, for example, an operation information signal due to a mouse operation on the screen displayed on the monitor device 42 via the mouse I / F 4018, the control unit 4010 makes a session connection request to the control unit 2810 of the IP-KVM switch 28 via the Internet 34 from the communication I / F 4012.

[0073] The control unit 2810 of the IP-KVM switch 28 that has received the session connection request establishes a session with the fire monitoring computer 18 and responds to the processing device 40.

[0074] The control unit 4010 of the processing device 40 that has received the response for session establishment converts the operation information signal into an operation information packet signal and transmits the operation information packet signal to the communication I / F 2816 of the IP-KVM switch 28 via the Internet 34.

[0075] The control unit 2810 of the IP-KVM switch 28 converts the operation information packet signal into an operation information signal and transmits it to the communication I / F 2814. The communication I / F 2814 transmits the operation information to the monitor I / F 1824 to end the process.

[0076] The control unit 1820 of the fire monitoring computer 18 performs an operation on the screen information based on the received operation information. At this time, on the screen of the monitor device 1810, the same mouse operation as that performed on the screen of the monitor device 42 at the remote site is displayed.

[0077] It is also possible to convert the operation information signal received by the communication I / F 2814 from the operation cables 24 and 26 into an operation information IP packet signal and transmit it from the communication I / F 2816 to the processing device 40 for the remote site.

[0078] [c. Receiver Screen and Monitor Screen at Remote Site] Next, the receiver screen and the monitor screen at the remote site will be described. For this description, refer to FIG. 3 showing the receiver screen and the monitor screen at the time of fire detection. Note that FIG. 3(A) shows the receiver screen and FIG. 3(B) shows the monitor screen.

[0079] The receiver screen 1410 in FIG. 3(B) is a fire alarm screen when the fire receiver 14 receives a fire alarm signal from the fire detector 16. Taking the analog fire detector with an address set as the fire detector 16 as an example, "001 Fire Occurrence, East Building, 1st Floor, Area 02, Main Pipe South, 1st Floor, Elevator Hall in Common Area" is displayed as the fire area information corresponding to the address of the fire detector that issued the fire alarm. Also, "16:50" is displayed as the fire occurrence time.

[0080] Figure 3(B) is a fire information screen displayed on the monitor device 42 of the remote site 12. The screen information signal generated by the fire monitoring computer 18 that received the fire information signal from the fire receiver 12 on which the receiver screen 1410 in Figure 3(A) was displayed is transmitted to the monitor device 42 via the IP-KVM switch 28, the VPN router 30, the Internet 34, the VPN router 36, and the processing device 40, and thus is displayed.

[0081] On the fire information screen of the monitor device 42, the fire reporting area is displayed in the fire reporting column 4210 at the upper part of the screen, and the floor plan 4214 of the "1st Floor, South of the Main Building", which is the floor where the fire broke out, corresponding to "View Floor Plan" in the next screen switching column 4212, is displayed.

[0082] Also, around the floor plan 4214, menu columns such as a reporting-related menu, screen switching, keep plan area, operation menu, floor display, etc. are arranged. Here, in the reporting-related menu, operation buttons such as the floor directly above, the floor where the fire broke out, the floor directly below, and the list of reporting floors are arranged, enabling quick confirmation of the floor plan of the required floor. Also, for screen switching, from the floor plan selection screen showing the entire monitoring area, the floor plan of the floor to be displayed can be selected by the switching buttons of "Upper Floor" and "Lower Floor".

[0083] Also, in the operation menu, selection buttons for "Sound Stop" and "Receiver Control" are arranged. In the floor display, floor buttons of the building are arranged, and the floor plan of the floor selected by a click operation using the mouse 46 is displayed. Additionally, the latest messages arranged below the floor plan 4214 display the latest fire reporting information in order.

[0084] By displaying the fire information screen shown in this Figure 3(B) on the monitor device 42 of the remote site 12, a monitor can remotely perform monitoring and operations equivalent to being in front of the fire monitoring computer 18 installed in the building 10 to be monitored.

[0085] [d. Processing Operations of the Disaster Prevention Monitoring System] Next, the processing operation of the disaster prevention monitoring system shown in FIG. 1 will be described. In this description, reference is made to FIG. 4, which is a time chart showing the processing operation of FIG. 1.

[0086] As shown in FIG. 4, the fire monitoring computer 18 installed in the building 10 generates screen information (step S1), and transmits the screen information signal to the monitor device 42 via the IP-KVM switch 28, VPN router 30, Internet 34, VPN router 36, and processing device 40. For example, when a fire information signal is received from the fire receiver 14 that has detected a fire and a fire is discriminated, a fire information screen as shown in FIG. 3(B) is displayed on the monitor device 42 (steps S2, S3).

[0087] When the processing device 40 discriminates a screen operation such as a fire information screen by an operation device, for example, an operation of the mouse 46 (Yes in step S4), an operation information signal is transmitted to the fire monitoring computer 18 via the VPN router 36, Internet 34, VPN router 30, and IP-KVM switch 28, and operation processing of the fire monitoring computer 18 by the mouse 46 of the processing device 40 is performed (steps S5, S6).

[0088] [e. Monitoring and operation of multiple buildings] Next, a disaster prevention monitoring system for monitoring and operating fire notification facilities in multiple buildings from a remote location will be described. In this description, reference is made to FIG. 5, which shows a disaster prevention monitoring system for remotely monitoring and operating fire notification facilities in multiple buildings.

[0089] (e1.
