[0006] The remote monitoring and operation of such a fire alarm system shall not have an adverse impact on the fire alarm system, and the remote monitoring and operation itself shall be carried out reliably. Furthermore, when remote monitoring is performed, simultaneous monitoring of multiple buildings is required at the monitoring center.

[0007] An object of the present invention is to provide a disaster prevention monitoring system that enables remote monitoring and operation of a plurality of fire alarm systems without the risk of being exposed to malicious attacks.

Means for Solving the Problems

[0008] (Disaster Prevention Monitoring System) The present invention is a disaster prevention monitoring system, For each of a plurality of buildings, A fire alarm system including a plurality of fire detectors for detecting a fire and a fire receiver for connecting the fire detectors and monitoring the fire, Based on the information output by the fire receiver, a fire monitoring computer that generates screen information related to fire monitoring, transmits a screen information signal, and receives an operation information signal from the outside, An IP-KVM switch that 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 a communication network, and 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, Comprising, At a remote site away from the building, A processing device for a remote site connected to the IP-KVM switch via a communication network, A monitor device connected to the processing device for a remote site via a video cable, An operation device connected to the processing device for a remote site via an operation cable, A notification device arranged near at least one of the monitor device and the operation device for giving an alarm by sound and / or display, Comprising, The fire monitoring computer transmits the generated screen information signal to the monitor device via the IP-KVM switch, communication network, and remote site processing device to display a screen based on the screen information. The remote site processing device can operate the fire monitoring computer with the operation device by transmitting the operation information signal received from the operation device to the fire monitoring computer via the communication network and IP-KVM switch. When the fire receiver detects a fire, the fire receiver or the fire monitoring computer outputs a fire information signal indicating that a fire has been detected to the outside. The notification device is characterized by giving an alarm at the remote site based on the received fire information signal.

[0009] (Transmission by IP conversion of fire signals) Each building is equipped with a first signal converter that converts the fire information signal into a fire information packet signal. Inside the remote site, a second signal converter that converts the fire information packet signal into a fire information signal is provided. The first signal converter converts the fire information signal output by the fire receiver or the fire monitoring computer into a fire information packet signal and transmits it to the second signal converter via the communication network. The second signal converter converts the received fire information packet signal into a fire information signal and transmits it to the notification device to give an alarm.

[0010] (Identification notification of fire object by notification device) The fire information signal includes fire object identification information indicating the building where the fire was detected. The notification device identifies and notifies which building the fire was detected in.

[0011] (Prompt selection of fire object with multi-view and alarm of notification device) The remote site processing device can simultaneously display on the monitor device a screen based on a plurality of pieces of screen information received from a plurality of different fire monitoring computers. The warning of the notification device prompts the selection operation of the fire-affected property that sent the fire information signal. By the selection operation of the fire-affected property using the operation device, the monitor device enlarges and displays the screen based on the screen information received from the fire monitoring computer of the selected fire-affected property, and the operation device can operate on the fire monitoring computer of the selected fire-affected property.

[0012] (Identification of fire-affected property using another terminal) The notification device is a terminal device installed near the mobile terminal carried by the monitor at the remote site and / or the processing device for the remote site. When the fire monitoring computer detects a fire, it transmits a fire information signal including the fact that a fire has been detected and the fire-affected property identification information indicating the building where the fire has been detected to the management server via the communication network. The management server transmits the fire-affected property identification information obtained from the fire information signal to the notification device, so as to notify the monitor of which building the fire has been detected in an identifiable manner.

[0013] (Identification of fire-affected property using an IP-KVM switch) When the monitor device functions as a notification device, When the fire monitoring computer detects a fire, it transmits a fire information signal including special character string information indicating that a fire has been detected and the fire-affected property identification information indicating the building where the fire has been detected to the processing device for the remote site via the operation cable, IP-KVM switch and communication network. When the processing device for the remote site receives the fire information signal, it emphasizes and displays the screen based on the screen information received from the fire monitoring computer that sent the fire information signal on the monitor device.

[0014] (Dualization of the disaster prevention monitoring system) Inside the building, a second fire monitoring computer that generates screen information related to fire monitoring based on the information output by the fire receiver, and A second IP-KVM switch connected to the second fire monitoring computer via a video cable, is provided, Inside the remote site, A second processing device for a second remote site connected to the second IP-KVM switch via a communication network, A second monitor device connected to the second processing device for the second remote site via a video cable, is provided, The second fire monitoring computer transmits the generated screen information to the second monitor device via the second IP-KVM switch, the communication network, and the second processing device for the second remote site, and displays a screen based on the screen information.

[0015] (Operation prohibition of the second processing device for the second remote site) The second processing device for the second remote site is configured such that the operation of the second fire monitoring computer by the operation information signal received from the second IP-KVM switch is impossible.

[0016] (Specific example of operation prohibition of the second processing device for the second remote site) The second processing device for the second remote site is set with a function to invalidate the transmission of the operation information signal to the second IP-KVM switch, or The connection by the operation cable between the second IP-KVM switch and the second fire monitoring computer is not connected.

Advantages of the Invention

[0017] (Effect of the disaster prevention monitoring system) The present invention is a disaster prevention monitoring system, which includes, for each of a plurality of buildings, a fire notification facility equipped with a plurality of fire detectors for detecting fires and a fire receiver for connecting the fire detectors to monitor fires, and a fire monitoring computer that generates screen information related to fire monitoring based on the information output by the fire receiver, transmits a screen information signal, and receives an operation information signal from the outside. An IP-KVM switch that 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 a communication network, and 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. A remote site processing device connected to the IP-KVM switch via a communication network at a remote site away from the building, a monitor device connected to the remote site processing device via a video cable, an operation device connected to the remote site processing device via an operation cable, and a notification device arranged near at least one of the monitor device and the operation device for giving an alarm by sound and / or display. The fire monitoring computer transmits the generated screen information signal to the monitor device via the IP-KVM switch, the communication network, and the remote site processing device to display a screen based on the screen information. The remote site processing device can operate the fire monitoring computer with the operation device by transmitting the operation information signal received from the operation device to the fire monitoring computer via the communication network and the IP-KVM switch. The fire receiver or the fire monitoring computer outputs an external fire information signal indicating that a fire has been detected when the fire receiver detects a fire. The notification device gives an alarm at the remote site based on the received fire information signal. By providing an IP-KVM switch between the communication network and the fire monitoring computer, the fire monitoring computer and the fire receiver cannot be directly specified in the network layer of the ISO reference model and are separated from the communication network, so it is possible to reliably defend against threats from malicious attacks from the communication network.In addition, since the alarm by the notification device is independent of the processing using the IP-KVM switch, it is carried out even when the session between the fire monitoring computer and the remote site processing device is not established, enabling the user to recognize that a fire has been detected promptly.

[0018] Also, when a fire is detected in any of a plurality of buildings on the monitor device connected to the remote site processing device, the screen information of the monitoring computer that detected the fire is displayed on the monitor device at the remote site, enabling the supervisor to appropriately grasp the situation of the fire occurrence and quickly perform the necessary countermeasure operations with the operation device.

[0019] In this case, even if the supervisor at the remote site does not constantly monitor the monitor device at the remote site, when a fire is detected in any of a plurality of buildings, an alarm is issued from the notification device at the remote site, and the supervisor can know the fire detection, view the screen information of the monitor device, and perform the necessary countermeasure operations, reducing the human burden due to constant monitoring.

[0020] (Effect of transmission by IP conversion of fire signal) Moreover, each building is equipped with a first signal converter that converts the fire information signal into a fire information packet signal, and the remote site is equipped with a second signal converter that converts the fire information packet signal into a fire information signal. The first signal converter converts the fire information signal output by the fire receiver or the fire monitoring computer into a fire information packet signal and transmits it to the second signal converter via the communication network. The second signal converter converts the received fire information packet signal into a fire information signal and transmits it to the notification device to issue an alarm. Therefore, separately from the IP communication of the operation information signal and the screen information signal by the IP-KVM switch, it is possible to IPize the fire information signal and surely transmit it to the notification device at the remote site to issue an alarm.

[0021] (Effect of identification notification of fire object by notification device) In addition, the fire information signal includes fire property identification information indicating the building in which a fire has been detected. Since the notification device can notify which building has detected a fire in an identifiable manner, the supervisor at the remote site can know the fire receiver at the fire origin from the alarm of the notification device and can respond quickly and appropriately.

[0022] (Effect of the selection operation of the fire property with the multi-view and the alarm of the notification device) In addition, the processing device for the remote site can display on the monitor device a screen based on a plurality of pieces of screen information received from a plurality of different fire monitoring computers at the same time. Due to the alarm of the notification device, the selection operation of the fire property that transmitted the fire information signal is promoted. By the selection operation of the fire property by the operation device, the screen based on the screen information received from the fire monitoring computer of the selected fire property is enlarged and displayed on the monitor device, and the operation device can operate on the fire monitoring computer of the selected fire property. Therefore, on the monitor device at the remote site, all the screen information transmitted from the fire monitoring computers of a plurality of buildings is displayed, for example, as a reduced multi-screen, so that a rough grasp of the fire monitoring status of all the buildings to be monitored is possible.

[0023] In addition, when a fire is detected in any of a plurality of buildings, the supervisor at the remote site is prompted to select the fire property that transmitted the fire signal by the alarm of the notification device. When the selection operation by the supervisor is performed on the operation device, the fire screen information of the fire property is enlarged and displayed, so that the fire screen information can be quickly viewed.

[0024] In addition, along with the selection operation of the fire property, the operation device at the remote site can operate the fire monitoring computer of the fire property. The supervisor at the remote site can perform operations necessary for fire response, such as switching operations between building floor plans on the upper and lower floors, by operating the operation device, and can confirm information necessary for evacuation guidance.

[0025] (Effect of identifying the fire property using another terminal, etc.) Further, the notification device is a terminal device installed near a mobile terminal carried by a monitor at a remote site and / or a processing device for the remote site. When the fire monitoring computer detects a fire with a fire receiver, it transmits a fire information signal including information indicating that a fire has been detected and fire object identification information indicating the building in which the fire has been detected to a management server via a communication network. The management server transmits the fire object identification information obtained from the fire information signal to the notification device to notify the user of which building the fire has been detected in an identifiable manner. Therefore, when the fire receiver detects a fire, the fire information signal is transmitted from the fire alarm computer to a mobile terminal as a notification device held by a monitor at a remote site via a communication path different from the communication path via the IP-KVM switch, for example, via the Internet and a server, and the fire object is identified and displayed, making it possible to easily transmit the fire information signal.

[0026] (Effect of identifying a fire object by utilizing an IP-KVM switch) Also, when the monitor device functions as a notification device, when the fire monitoring computer detects a fire with a fire receiver, it transmits a fire information signal including special character string information indicating that a fire has been detected and fire object identification information indicating the building in which the fire has been detected to a processing device for the remote site via an operation cable, an IP-KVM switch, and a communication network. When the processing device for the remote site receives the fire information signal, it highlights and displays on the monitor device a screen based on the screen information received from the fire monitoring computer that transmitted the fire information signal. Therefore, the fire monitoring computer that detected the fire outputs a fire information signal including special character string information, for example, meaningless character string information such as "ALSKDJFHG", and fire object identification information to the IP-KVM switch via an operation cable, and transmits it to the processing device for the remote site as a fire information packet signal. With a simple system configuration that does not require a signal converter for IP conversion of the fire signal, the cost can be reduced.

[0027] In addition, fire information based on the fire information signal is received by the processing device for the remote site, and it becomes possible to emphasize and display on the monitor device a screen based on the screen information received from the fire monitoring computer, eliminating the need to install a notification device for alarming the remote site of a fire detection, thus simplifying the system configuration and reducing costs.

[0028] (Effect of Duplication of the Disaster Prevention Monitoring System) In addition, inside the building, a second fire monitoring computer that generates screen information related to fire monitoring based on the information output by the fire receiver, and a second IP-KVM switch connected to the second fire monitoring computer via a video cable are provided. Inside the remote site, a second processing device for the remote site connected to the second IP-KVM switch via a communication network, and a second monitor device connected to the second processing device for the remote site via a video cable are provided. The second fire monitoring computer transmits the generated screen information to the second monitor device via the second IP-KVM switch, the communication network, and the second processing device for the remote site to display a screen based on the screen information. By duplicating the disaster prevention monitoring system, it becomes possible to enhance the reliability of monitoring and operation for multiple buildings.

[0029] (Effect of Prohibiting Operation of the Second Processing Device for the Remote Site) In addition, the second processing device for the remote site is configured such that the operation of the second fire monitoring computer by the operation information signal received from the second IP-KVM switch is impossible. For example, a function for invalidating the transmission of the operation information signal to the second IP-KVM switch is set in the second processing device for the remote site, or the connection by the operation cable between the second IP-KVM switch and the second fire monitoring computer is not connected. Therefore, with the duplication of the disaster prevention monitoring system, the second processing device for the remote site can easily adopt an operation mode in which it can only monitor by displaying screen information and cannot perform operations. With such a configuration, even if the second processing device for the remote site is placed in a location with low security, such as a passageway, the second processing device for the remote site can operate without security problems, thus increasing the installation flexibility of the second processing device for the remote site.

Embodiments for Carrying Out the Invention

[0031] Hereinafter, embodiments 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.

[0032] [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.

[0033] Here, the "fire notification equipment" of the building is equipped with a fire receiver that monitors a fire by connecting a plurality of fire detectors.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] In addition, the "screen information related to fire monitoring" generated by the fire monitoring computer is arbitrary, and includes, for example, fire alarm information indicating the fire occurrence location and time of the building, a floor plan of the building such as the floor where the fire breaks out that can be switched on the screen, and the upper and lower floors of the building.

[0038] In addition, an "IP-KVM switch" is a device that IP-ifies (Internet-protocol-ifies) the signals of a keyboard, video, and mouse, that is, converts them into packet signals according to Internet protocol (TCP / IP conversion), enabling access to and control of various devices such as computers and servers via networks such as LANs and the Internet.

[0039] The "IP-KVM switch" of 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 also 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.

[0040] In addition, a "remote site" is a facility such as a monitoring center installed in another building far from the building, meaning a place where a monitor can be stationed to remotely monitor and operate the fire notification equipment in the building.

[0041] The "remote site" of the embodiment is provided with a remote-site processing device, a monitor device, and an operation device. Here, the "remote-site processing device" is a device connected to the IP-KVM switch via a communication network. For example, a computer is used.

[0042] In addition, the "monitor device" is a display device connected to the remote-site processing device via a video cable. The "operation device" is a device connected to the remote-site processing device via an operation cable and includes a keyboard, a mouse, and the like.

[0043] The "fire monitoring computer" of the embodiment transmits the generated screen information to the monitor device via the IP-KVM switch, the communication network, and the remote-site processing device to display the screen information.

[0044] In addition, the "processing device for remote site" in the embodiment enables the operation of the fire monitoring computer by the operation device by transmitting the operation information signal received from the operation device to the fire monitoring computer via the communication network and the IP-KVM switch.

[0045] Here, the fire monitoring computer viewed from the IP-KVM switch is on the server side of the client-server system, and the processing device for remote site is on the client side, and it is in a form of remotely monitoring and operating the server side from the client side.

[0046] Therefore, by providing the "IP-KVM switch" for the monitoring and operation of the building's fire notification equipment at the 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.

[0047] In addition, by providing the "IP-KVM switch", the screen information signal of the fire monitoring computer is IP-enabled and the screen information is displayed at the remote site via the communication network, enabling remote operation of the fire monitoring computer by the operation device at the remote site.

[0048] The "communication network" connecting the building side and the remote site side is arbitrary and includes wireless communication networks such as the Internet known as the public communication network, G3, LET, G4, WiFi (registered trademark), etc.

[0049] In addition, there are multiple "buildings", and a fire receiver, a disaster monitoring computer, and an IP-KVM switch are provided for each building.

[0050] In this case, the "processing device for remote sites" can display on the monitor device the screens based on the multiple screen information received from multiple different fire monitoring computers simultaneously. Also, the "processing device for remote sites" 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.

[0051] Furthermore, the "processing device for remote sites" enables operations on the fire monitoring computer of the fire incident building selected by the operation device using the operation device.

[0052] Therefore, on the monitor device connected to the processing device for remote sites, the screens of the fire monitoring computers of multiple buildings (incidents) are displayed as, for example, reduced screens, enabling a general understanding of the fire monitoring status of all buildings (incidents) under monitoring.

[0053] Also, when the monitor operator selects and operates a fire incident building with respect to the processing device for remote sites, the fire screen is enlarged and displayed among the multiple reduced screens displayed on the monitor device of the processing device for remote sites, enabling an appropriate understanding of the fire occurrence situation and enabling the rapid performance of the necessary fire response operations using the operation device.

[0054] Also, in the embodiment, a notification device that gives an alarm by sound and / or display is arranged near at least one of the monitor device and the operation device at the remote site. Correspondingly, the fire monitoring computers provided for each of the multiple buildings output a fire information signal indicating that a fire has been detected when the fire receiver detects a fire, and at the remote site, an alarm is given by the notification device based on the fire information.

[0055] Therefore, even if the monitor at the remote site does not constantly monitor the monitoring device at the remote site, if a fire is detected in any of the multiple buildings, an alarm will be issued from the notification device at the remote site, and the monitor only needs to view the screen information of the monitoring device when the alarm is issued and perform the necessary coping operations, thus reducing the human burden caused by constant monitoring.

[0056] In addition, a first signal converter is provided for each building, and a second signal converter is also provided at the remote site. The fire information signal from the fire monitoring computer is converted into a fire information packet signal by the first signal converter, and the fire information packet signal is converted back into a fire information signal by the second signal converter at the remote site.

[0057] When the fire receiver detects a fire, the fire monitoring computer transmits the fire information signal to the second signal converter at the remote site via the first signal converter and the communication network. The second signal converter transmits the received fire information signal to the notification device to trigger an alarm.

[0058] Therefore, apart from the IP communication of the operation information signal and the screen information signal by the IP-KVM switch, it is possible to IPify the fire information signal and reliably transmit it to the notification device at the remote site to trigger an alarm.

[0059] In addition, the fire information signal transmitted from the fire monitoring computer contains the fire object identification information indicating the building where the fire was detected. Therefore, the notification device can notify the monitor in an identifiable manner which building detected the fire.

[0060] Also, the processing device for the remote site can simultaneously display on the monitoring device the screens based on the multiple screen information received from multiple different fire monitoring computers. When the alarm of the notification device is triggered upon receiving the fire information signal, the monitor is prompted to perform a selection operation on the fire object indicating the fire monitoring computer that transmitted the fire information signal.

[0061] When a monitor selects a fire-affected property using an operation device, a screen based on the screen information received from the fire monitoring computer of the selected fire-affected property is enlarged and displayed on the monitor device. Also, operations can be performed on the fire monitoring computer of the selected fire-affected property using the operation device.

[0062] For this reason, on the monitor device at the remote site, all of the screen information transmitted from the fire monitoring computers of multiple buildings is displayed, for example, as a reduced multi-screen, enabling a rough understanding of the fire monitoring status of all the buildings being monitored.

[0063] Also, when a fire is detected in any of the multiple buildings, the monitor at the remote site is prompted to select the fire-affected property by the alarm of the notification device. When the selection operation by the monitor is performed on the operation device, the fire screen information of the fire-affected property is enlarged and displayed, enabling the fire screen information to be quickly viewed.

[0064] Also, with the selection operation of the fire-affected property, operations on the fire monitoring computer of the fire-affected property can be performed using the operation device at the remote site. Thus, the monitor at the remote site can perform operations necessary for fire response, such as switching operations between building floor plans of upper and lower floors, to confirm information necessary for evacuation guidance.

[0065] Also, the notification device of the embodiment receives a signal based on a fire information signal including fire-affected property identification information indicating the building in which the fire detector that detected the fire is installed, enabling identification of which fire detector detected the fire and providing notification. For this reason, it becomes possible for the monitor at the remote site to know the fire detector at the fire origin from the alarm of the notification device and respond quickly and appropriately.

[0066] In addition, the notification device of the embodiment is a mobile terminal carried by a supervisor of the remote site processing device and / or a terminal device installed near the remote site processing device. In this case, when the fire monitoring computer detects a fire, the fire monitoring computer transmits a fire information signal including the fact that a fire has been detected and fire object identification information indicating the building in which the fire has been detected to the management server via a communication network. The management server transmits the fire object identification information obtained from the signal based on the received fire information signal to the notification device, and the notification device notifies in an identifiable manner which building (object) the fire has been detected in.

[0067] Therefore, a signal based on the fire information signal is transmitted to the mobile terminal functioning as a notification device via a communication path different from the communication path via, for example, the IP-KVM switch held by the supervisor at the remote site, such as a communication path via the Internet and the management server, and the fire object is notified in an identifiable manner, and the fire information signal can be easily transmitted to the remote site side for warning without requiring a signal converter for transmitting the fire information signal to the Internet.

[0068] In addition, in the embodiment, the monitor device at the remote site functions as a notification device. In this case, when the fire monitoring computer detects a fire, the fire monitoring computer transmits a fire information signal including special character string information indicating that a fire has been detected and fire object identification information to the remote site processing device via an operation cable, an IP-KVM switch, and a communication network. When the remote site processing device receives the fire information signal, the target object displayed on the screen of the monitor device is highlighted and displayed.

[0069] Therefore, when a fire is detected by the fire receiver, a fire information signal including special character string information, for example, meaningless character string information such as "ALSKDJFHG", and fire object identification information is output from the fire monitoring computer to the IP-KVM switch via the operation cable and transmitted to the remote site processing device as a fire information packet signal. As a result, a signal converter for IPifying the fire information signal is made unnecessary, the system configuration is simplified, and the cost can be reduced.

[0070] In addition, when the fire information signal is received by the processing device for the remote site, the target property displayed on the screen of the monitoring device can be highlighted and displayed. Further, it becomes unnecessary to install a notification device for warning the remote site side to identify the fire property, the system configuration can be simplified, and the cost can be reduced.

[0071] Further, the embodiment includes, for each building, a second fire monitoring computer that generates screen information related to fire monitoring based on the information output by the fire receiver, and a second IP-KVM switch connected to the second fire monitoring computer via a video cable. Further, inside the remote site, a second processing device for the remote site connected to the second IP-KVM switch via a communication network, and a second monitoring device connected to the second processing device for the remote site via a video cable are provided.

[0072] The second fire monitoring computer transmits the generated screen information to the second monitoring device via a video cable, a second IP-KVM switch, a communication network, and a second processing device for the remote site, and displays a screen based on the screen information.

[0073] Therefore, by duplicating the disaster prevention monitoring system, it becomes possible to improve the reliability of monitoring for multiple buildings.

[0074] In addition, in order to enable an operation mode in which only monitoring is performed by the second processing device for the remote site and the second monitoring device, the second fire monitoring computer is configured to be unable to be operated by an operation information signal from the second processing device for the remote site received from the second IP-KVM switch.

[0075] As a configuration for this, the second processing device for the remote site is provided with a function of invalidating the operation information signal from the operation device.

[0076] As another configuration, the connection between the second fire monitoring computer and the second IP-KVM switch by the operation cable is disconnected.

[0077] The following describes specific embodiments. In the specific embodiments shown below, the case where the "communication network" is the "Internet", the "signal converter" is a "LAN converter", the "processing device for remote sites" is a "processing device", the "operation device" is a "keyboard or mouse", and the "notification device" is an "alarm lamp" or an "alarm display" will be described.

For this description, refer to FIG. 1 showing a disaster prevention monitoring system that monitors and operates the fire alarm equipment of a building from a remote site.

[0080] 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.

[0081] 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.

[0082] The fire receiver 14 and the fire monitoring computer 18 constitute a fire notification facility. The fire receiver 14 is installed in the building manager's room or the monitoring center of building 10, and a plurality of fire sensors 16 are connected to a sensor line 15 laid in the building from the fire receiver 14.

[0083] There are R-type and P-type fire notification facilities. The embodiment is an R-type fire notification facility, in which a plurality of analog fire sensors 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 sensor 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.

[0084] 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 sensors 16 are connected to a signal line laid for each area from the fire receiver 14. When the fire sensor 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.

[0085] 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 issues 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.

[0086] 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. Based on the fire information signal output by the fire receiver 14, the fire monitoring computer 18 generates screen information related to fire monitoring and displays it on the monitor device 1810.

[0087] 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.

[0088] 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 alarm floors, the next alarm floor, 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.

[0089] 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.

[0090] 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 referred to as a virtual Internet.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] The processing device 40 transmits an operation information signal from the operation device 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 device of the keyboard 44 or the mouse 46 of the processing device 40.

[0096] [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.

[0097] 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.

[0098] 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.

[0099] The IP-KVM switch 28 includes a control unit 2810, a memory 2812, a communication I / F 2814 on the side of the fire monitoring computer 18, and a communication I / F 2816 on the side of the communication network.

[0103] The operation for communicating the screen information signal from the fire monitoring computer 18 to the processing device 40 is as follows.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] The control unit 4010 of the processing device 40 that has received the response to the 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.

[0111] 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.

[0112] The control unit 1820 of the fire monitoring computer 18 performs operations on the screen information based on the received operation information. At this time, on the screen of the monitor device 1810, the same mouse operations as those performed on the screen of the monitor device 42 at the remote site are displayed.

[0113] 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.

[0114] [c. Receiver Screen and Monitor Screen at Remote Site] Next, the receiver screen and the monitor screen at the remote site will be described. In this description, refer to FIG. 3 showing the receiver screen and the monitor screen at the time of fire detection.

[0163] The fire information transmission unit 96 outputs a fire information signal including special character string information having no special meaning and fire incident identification information indicating the building in which a fire has been detected, as information indicating that a fire has been detected, to the IP-KVM switch 28 via the operation cable 24. The special character string information set in the fire information signal is arbitrary, for example, "ALSKDJFGH" or the like.

[0164] Also, the special character string information set in the fire information signal has the same number of characters, but is different special character string information for each of buildings 10(10-1) to 10(10-6). Therefore, on the remote site 12 side, the fire receiver 14 that is the fire incident can be identified from the received special character string information.

[0165] At the remote site 12, similar to the remote site 12 in FIG. 1, a VPN router 36, a processing device 40, a monitor device 42, and a keyboard 44 and a mouse 46 as operation devices are provided. However, an alarm device for identifying and alarming the fire receiver that has detected a fire is not provided.

[0166] In this embodiment, the monitor device 42 is provided with the function as an alarm device. When the processing device 40 receives a fire information signal from the building side, it identifies that a fire has been detected and the fire receiver that has detected the fire from the special character string information included in the fire information signal, and highlights and displays it on the screen of the monitor device 42.

[0167] Specifically, among the property selection buttons of "Property A" to "Property F" arranged in the property selection area 80 of the normal monitor device 42 shown in FIG. 8, the property selection button corresponding to fire detection is changed to a predetermined display color, for example, red, and further emphasized by flashing or flickering.

[0168] Therefore, when the monitor at the remote site clicks on the property selection button highlighted on the monitor device 42 by mouse operation, the screen of the clicked fire property displayed in the monitored property area 78 is enlarged and displayed.

[0169] [h. Dual-redundant disaster prevention monitoring system] Next, the dual-redundant disaster prevention monitoring system will be described. In this description, refer to FIG. 14 showing the dual-redundant disaster prevention monitoring system that enables monitoring and operation from different remote sites.

[0170] As shown in FIG. 14, in this embodiment, in buildings 10(10-1) to 10(10-6), as represented by building 10(10-1), similar to the case of building 10 in FIG. 1, a fire receiver 14, a fire monitoring computer 18, an IP-KVM switch 28, and a VPN router 30 are provided. In addition to this, in this embodiment, a second fire monitoring computer 98 and a second IP-KVM switch 100 are provided.

[0171] The second fire monitoring computer 98 is connected to the fire receiver 14 by a transmission cable 20, and like the fire monitoring computer 18, receives a fire information signal from the fire receiver 14. The second fire monitoring computer 98 is connected to the second IP-KVM switch 100 by a video cable 99, and the second IP-KVM switch 100 converts the fire information signal into an IP packet signal (fire information packet signal) and transmits it to the Internet 34 via the VPN router 30.

[0172] Here, the fire monitoring computer 18 is connected to the IP-KVM switch 28, the video cable 22, and the operation cables 24 and 26. However, the second fire monitoring computer 98 and the second IP-KVM switch 100 are connected only by the video cable 99, and are not connected by the operation cable. For this reason, the second fire monitoring computer 98 cannot be operated from the remote site side.

[0173] At the remote site 12, as the first system 12A, similar to the remote site 12 in FIG. 1, a VPN router 36, a processing device 40, a monitor device 42, and a keyboard 44 and a mouse 46 as operation devices are provided.

[0174] In addition to this, in the present embodiment, at the same remote site 12, as a new second system 12B, similar to the first system 12A, a VPN router 102, a processing device 104, a monitor device 106, and a keyboard 108 and a mouse 110 as operation devices are provided.

[0175] The first system 12A monitors and operates the fire monitoring computers 18 of the buildings 10(10-1) to 10(10-6), but the second system 12B is provided only for monitoring the second fire monitoring computers 98 of the buildings 10(10-1) to 10(10-6).

[0176] For this reason, even if an operator performs screen operation of the monitor device 106 with the keyboard 108 or the mouse 110 which are operation devices of the second system 12B and the operation information signal is sent to the second IP-KVM switch 100 of the building 10(10-1) for example, in the present embodiment, since there is no connection of the operation cable, the second fire monitoring computer 98 cannot be operated.

[0177] As another configuration for prohibiting the operation from the second system 12B, the processing device 104 may be provided with a function of invalidating the operation information signal by the operations of the keyboard 108 and the mouse 110 and not outputting it to the VPN router 102.

[0178] [i. Modifications of the present invention] A modification of the disaster prevention monitoring system according to the present invention will be described. The disaster prevention monitoring system of the present invention includes the following modifications in addition to the above-described embodiment.

[0179] (Minimum configuration of the fire monitoring computer) In the above-described embodiment, a monitor device, a keyboard, and a mouse are connected to the fire monitoring computer. However, when the building side does not perform monitoring and operation by the fire monitoring computer 18 and only the processing device at the remote site performs monitoring and operation, the fire monitoring computer 18 may have a minimum configuration without providing a monitor device, a keyboard, and a mouse.

[0180] (Fault detection of the fire receiver) Also, in the above-described embodiment, when the fire receiver 14 receives a fire alarm signal from the fire detector 16, a fire information signal is output to the fire monitoring computer 18, the fire monitoring computer 18 generates fire screen information, and the fire screen information signal is transmitted to the remote site 12 side via the IP-KVM switch 28 to display the fire screen information on the monitor device 42. However, when the fire receiver 14 detects a fault, a fault information signal may be output to the fire monitoring computer 18, the fire monitoring computer 18 generates fault screen information, and the fault screen information signal is transmitted to the remote site 12 side via the IP-KVM switch 28 to display the fault screen information on the monitor device 42.

[0181] (Others) Also, 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.
