[0001] The present invention relates to a disaster prevention information linkage system that manages various disaster prevention information related to fires, disasters, earthquakes, floods, etc. monitored in disaster prevention facilities in a dual disaster prevention information infrastructure system and links the disaster prevention information to a linked system.

Background Art

[0002] Conventionally, secondary utilization of disaster prevention information related to fires, disasters, etc. monitored by fire alarm equipment, which is a type of disaster prevention equipment, such as receiving and displaying it on terminals of users, etc. other than the fire alarm equipment, is limited to areas such as transfer report linkage by contact transfer report signals from the fire alarm equipment and equipment internal linkage using the BAS standard protocol (BACnet, etc.) that unifies communication specifications for air conditioning equipment, lighting equipment, electrical equipment, security and disaster prevention equipment, etc. within the facility. Linkage of disaster prevention information using public lines such as the Internet has been avoided from the perspective that it is difficult to guarantee its reliability.

[0003] Therefore, in the linkage of disaster prevention information using public lines, for the purpose of improving stable operation and resilience (disaster recovery ability) in case of disasters and guaranteeing its reliability, a disaster prevention information infrastructure constructed as a platform on a cloud server that can be communicatively connected via the Internet is duplicated, so that even if an abnormality occurs in one disaster prevention information infrastructure system, the disaster prevention information that is also managed by the other disaster prevention information infrastructure system can be transmitted to the linked system. A disaster prevention information linkage system has been studied.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the anomaly monitoring of the redundant disaster prevention information infrastructure system on cloud servers relies primarily on software monitoring on the cloud servers, and there are challenges in the real-time nature of this monitoring.

[0006] Furthermore, when sharing disaster prevention information using public networks, the system being shared may belong to another entity, and its specifications may differ significantly from the company's own disaster prevention information infrastructure system built on a cloud server. This makes it difficult to monitor for anomalies using the cloud server software, including the information management system of the partner entity.

[0007] Furthermore, since fires and disasters do not occur frequently, event signals containing disaster prevention information are not constantly transmitted from each disaster prevention facility. Therefore, under normal operation, it is difficult to comprehensively check the communication status from each disaster prevention facility through the disaster prevention information infrastructure system to the linked system using event signals.

[0008] The present invention aims to provide a disaster prevention information linkage system that, in normal operation, enables monitoring of the operating status of the disaster prevention information linkage system from the actual equipment to the linked system via a redundant disaster prevention information infrastructure system, thereby improving the certainty, stability, and reliability of disaster prevention information linkage. [Means for solving the problem]

[0009] (Disaster Prevention Information Sharing System) The present invention relates to a disaster prevention information linkage system comprising a linked information management system that transmits an event signal containing event information indicating a predetermined event occurring in actual equipment performing disaster prevention monitoring to each of a redundant first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system, and transmits an event signal containing event information from at least one of the first or second disaster prevention information infrastructure system to a linked system, the linked system receives the event signal and transmits a signal based on the event signal to the user terminal, and Simulated equipment installed in a communication environment that simulates the communication environment from the actual equipment to the first disaster prevention information infrastructure system, and the communication environment from the actual equipment to the second disaster prevention information infrastructure system, A test terminal connected to the partner system's information management system, Equipped with, pseudo The system is characterized by transmitting a pseudo-event signal in the same signal format as an event signal to a first communication path that goes from the same equipment to a test terminal via the first disaster prevention information infrastructure system, and to a second communication path that goes from the second disaster prevention information infrastructure system to a test terminal, thereby detecting the communication status of the first and second communication paths.

[0010] (Monitoring of communication time) As part of detecting the communication status of the first and second communication paths, the communication time required for the pseudo-event signal via the first communication path and the communication time required for the pseudo-event signal via the second communication path are detected.

[0011] (Average communication time) The detection of communication duration involves detecting the average value of the communication duration for the first communication path and the average value of the communication duration for the second communication path over a predetermined number of cycles.

[0012] (Detection of communication time) The simulated equipment is, pseudo Includes event information that makes each of the similar event signals identifiable. pseudo Along with sending a similar event signal, pseudo The transmission time and transmission of the event signal pseudo The event information contained in the event signal is matched with the transmission time information, which is then sent to the test terminal. The test terminal is, pseudo The reception time when a similar event signal was received and pseudo Detect event information contained in the event signal, pseudoBased on the transmission time corresponding to the event information detected from the transmission time information received from the pseudo-device and the detected reception time, detect the communication required time of the pseudo-event signal via the first communication path and the communication required time of the pseudo-event signal via the second communication path.

[0013] (Communication path of transmission time information) The transmission time information does not pass through the partner information management system. email Via the communication path , test terminal It is transmitted.

[0014] (Judgment of system operating state) If both the communication required time of the first communication path and the communication required time of the second communication path satisfy the predetermined allowable time condition, it is judged that the disaster prevention information cooperation system is normal, If the communication required time of the first communication path does not satisfy the allowable time condition and the communication required time of the second communication path satisfies the allowable time condition, it is judged that there is an abnormality in the first disaster prevention information infrastructure system, If the communication required time of the first communication path satisfies the allowable time condition and the communication required time of the second communication path does not satisfy the allowable time condition, it is judged that there is an abnormality in the second disaster prevention information infrastructure system, If both the communication required time of the first communication path and the second communication path do not satisfy the allowable time condition, it is judged that there is an abnormality in the disaster prevention information cooperation system.

[0015] (Abnormality response of dual system) Of the duplicated first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system, one operates as the main system and the other operates as the sub-system, If an abnormality is judged in the first disaster prevention information infrastructure system or the second disaster prevention information infrastructure system operating as the main system, stop the disaster prevention information infrastructure system operating as the main system and switch the disaster prevention information infrastructure system operating as the sub-system to the main system for operation.

[0016] (User terminal and test terminal) The user terminal displays event information included in a signal based on an event signal. The test terminal is a terminal corresponding to the type of user terminal arranged in the same communication environment as the user terminal. pseudo It displays the communication states of the first communication path and the second communication path from the virtual facility to itself.

[0017] (Communication connection between the actual facility and the virtual facility) The actual facility is communicatively connected to the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system using a predetermined wireless communication device. The virtual facility is installed at the installation location of the actual facility and is communicatively connected to the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system via the wireless communication device used in the actual facility.

[0018] (Virtual facility) The actual facility is a disaster prevention facility equipped with a sensor and a receiver. The virtual facility is a virtual receiver corresponding to the receiver, or a virtual receiver function realized by the execution of a program by a computer.

Advantages of the Invention

[0019] (Effects of the disaster prevention information cooperation system) The present invention transmits an event signal including event information indicating a predetermined event occurring in an actual facility for disaster prevention monitoring to each of the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system that are duplicated, and transmits an event signal including event information from at least either the first disaster prevention information infrastructure system or the second disaster prevention information infrastructure system to a cooperation destination system. The cooperation destination system is a disaster prevention information cooperation system including a cooperation destination information management system that receives the event signal and transmits a signal based on the event signal to the user terminal. The system includes a virtual facility installed in a communication environment that simulates the communication environment from the actual facility to the first disaster prevention information infrastructure system and the communication environment from the actual facility to the second disaster prevention information infrastructure system, and a test terminal connected to the cooperation destination information management system in the cooperation destination system. pseudoThe system transmits pseudo-event signals in the same signal format as event signals to both the first communication path, which goes from the simulcast equipment through the first disaster prevention information infrastructure system to the test terminal, and the second communication path, which goes from the second disaster prevention information infrastructure system to the test terminal, thereby detecting the communication status of the first and second communication paths. Therefore, in normal operation, event signals are not transmitted from the actual equipment. pseudo From similar equipment pseudo The system can detect the communication status of the disaster prevention information linkage system from the event signal to the test terminal via a redundant disaster prevention information infrastructure system. This allows for constant monitoring of whether the disaster prevention information linkage system is operating normally or abnormally based on the communication status, thereby improving the reliability, stability, and trustworthiness of disaster prevention information linkage.

[0020] Furthermore, even if one of the two redundant disaster prevention information infrastructure systems is in standby mode and does not send event signals to the linked system, without using event signals pseudo From similar equipment pseudo By using event signals to detect the communication status of the disaster prevention information sharing system, it becomes possible to constantly monitor whether the operation status of the disaster prevention information sharing system is normal or abnormal, including the disaster prevention information infrastructure system which is in a standby state and does not transmit event signals.

[0021] (Effects of monitoring communication time) Furthermore, as part of detecting the communication status of the first and second communication paths, the system detects the communication time required for a pseudo-event signal via the first communication path and the communication time required for a pseudo-event signal via the second communication path. Based on the detected communication times of the first and second communication paths, it becomes possible to predict abnormalities before they lead to failures (malfunctions) due to performance degradation of the disaster prevention information sharing system, the equipment and devices that constitute the system, etc.

[0022] (Effect of detecting communication time) The simulated equipment is, pseudo Includes event information that makes each of the similar event signals identifiable. pseudo Along with sending a similar event signal, pseudo The transmission time and transmission of the event signal pseudo The test terminal receives transmission time information corresponding to the event information contained in the event signal, and the test terminal then... pseudo The reception time when a similar event signal was received and pseudo Detect event information contained in the event signal, pseudo Based on the transmission time and reception time corresponding to the event information detected from the transmission time information received from the equipment, the communication time required for the pseudo-event signal via the first communication path and the communication time required for the pseudo-event signal via the second communication path are detected. Therefore, the transmission is transmitted via the first communication path and the second communication path, which are different communication paths. pseudo Regarding simulated event signals, the communication time can be individually detected from the transmission time of the simulated event signal from the simulated equipment and the reception time of the simulated event signal at the test terminal, enabling accurate determination of whether the disaster prevention information sharing system is operating normally or abnormally.

[0023] (Effect of the communication path for transmission time information) Furthermore, since the transmission time information is transmitted via a communication path that does not go through the linked information management system, even if the linked information management system uses a communication protocol that does not send transmission time information to the user terminal, the test terminal can obtain the transmission time information, and the test terminal can obtain the transmission time information regardless of the configuration of the linked system.

[0024] (Effect of determining the system's operating status) Furthermore, if both the communication time of the first communication path and the communication time of the second communication path satisfy the predetermined allowable time conditions, the disaster prevention information sharing system is judged to be normal. If the communication time of the first communication path does not satisfy the allowable time conditions, but the communication time of the second communication path does, the first disaster prevention information infrastructure system is judged to be abnormal. If the communication time of the first communication path satisfies the allowable time conditions, but the communication time of the second communication path does not, the second disaster prevention information infrastructure system is judged to be abnormal. If both the communication time of the first and second communication paths do not satisfy the allowable time conditions, the disaster prevention information sharing system is judged to be abnormal. pseudo If the communication time of the pseudo-event signal is within the allowable time, it can be confirmed that the disaster prevention information sharing system, the equipment and devices that constitute the system, etc., are operating normally. On the other hand, if the communication time of the pseudo-event signal exceeds the allowable time in either the first communication path or the second pseudo-communication path, it becomes possible to confirm that one of the systems included in the disaster prevention information sharing system, the equipment and devices that constitute the system, etc., is abnormal, enabling prediction of abnormalities before failure or malfunction occurs, and allowing for appropriate countermeasures in advance. Furthermore, the location of the abnormality can be identified from the communication path where the communication time exceeds the allowable time, enabling appropriate countermeasures.

[0025] (Effectiveness of handling anomalies in a redundant system) Furthermore, the redundant first and second disaster prevention information infrastructure systems operate with one as the main system and the other as a subsystem. If an abnormality is detected in either the first or second disaster prevention information infrastructure system operating as the main system, the system operating as the main system is shut down, and the system operating as a subsystem is switched to operate as the main system. This allows for switching between the main and subsystem systems of the redundant disaster prevention information infrastructure system based on the results of determining the operating status of the disaster prevention information linkage system based on the communication time, thereby improving the certainty, stability, and reliability of the operation to link disaster prevention information to the linked system.

[0026] (Effectiveness of user terminals and test terminals) Furthermore, the user terminal displays event information contained in the signal based on the event signal, and the test terminal is a terminal corresponding to the type of user terminal that is placed in the same communication environment as the user terminal. pseudo By displaying the communication status of the first and second communication paths from the equipment to itself, if the linked system that receives disaster prevention information uses various types of user terminals such as smartphones, tablets, and personal computers, a test terminal of the type corresponding to the type of user terminal is prepared, and the communication status of the first and second communication paths is detected for each test terminal, a format similar to the sharing of disaster prevention information by sending event signals is achieved. pseudo By transmitting similar event signals, it becomes possible to more accurately monitor anomalies in the disaster prevention information sharing system.

[0027] (Communication environment between actual equipment and simulated equipment) Furthermore, the actual equipment is connected to the first and second disaster prevention information infrastructure systems using designated wireless communication devices, while the simulated equipment is installed at the same location as the actual equipment and connected to the first and second disaster prevention information infrastructure systems via the wireless communication devices used in the actual equipment. This makes the communication environment between the actual and simulated equipment as similar as possible, and closely resembles the coordination of disaster prevention information through the transmission of event signals. pseudo By sending event signals, the system more accurately monitors for abnormalities in the operation status of the disaster prevention information sharing system.

[0028] (Effects of simulated equipment) Furthermore, since the actual equipment is a disaster prevention system equipped with fire detectors and receivers, and the simulated equipment is a simulated receiver corresponding to the receiver, or a simulated receiver function realized by executing a simulated program on a computer, there is no need to have the receiver of the disaster prevention system send a simulated event signal to monitor the operating status of the disaster prevention information linkage system, thereby interrupting disaster prevention monitoring and disaster prevention information linkage operations. In addition, in order to monitor abnormalities in the operating status of the disaster prevention information linkage system, pseudo Similar equipment pseudo Since it only needs to transmit event signals and does not require monitoring for events such as fires or malfunctions as in actual equipment, the configuration can be kept to a minimum, thus reducing costs.

[0030] The following describes in detail an embodiment of the disaster prevention information sharing system according to the present invention, based on the drawings. However, the present invention is not limited to the following embodiments.

[0031] [Basic Concepts of the Embodiment] First, let me explain the basic concept of the embodiment. The embodiment is, in general terms, related to a disaster prevention information sharing system.

[0032] A disaster prevention information sharing system is a system that transmits event signals, which include event information indicating predetermined events that occur at actual equipment used for disaster prevention monitoring, such as fires or malfunctions that occur in buildings equipped with fire alarm systems, to a disaster prevention information infrastructure system that can communicate via a general-purpose public communication network, including the internet. The disaster prevention information infrastructure system then transmits the event signals to partner systems that will share disaster prevention information, thereby sharing disaster prevention information.

[0033] Furthermore, the disaster prevention information infrastructure system comprises a redundant first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system. Event signals transmitted from actual equipment are sent to the linked system from at least one of the first or second disaster prevention information infrastructure system, with one operating as the main system and the other as a subsystem. The linked system also includes a linked information management system that receives event signals and sends signals based on those event signals to user terminals.

[0034] Here, "disaster prevention information infrastructure system" refers to a place for collecting and managing disaster prevention information based on event signals transmitted from actual equipment. It is a computer system that can communicate via a general-purpose public communication network such as the Internet, for example, a disaster prevention information platform using a cloud server, and is a concept that includes equipment and devices for building such a system. Furthermore, "disaster prevention information" is a concept that includes various types of information that cause damage to people's lives and society, such as fires, crimes, earthquakes, and floods.

[0035] Furthermore, the "disaster prevention information infrastructure system operating as the main system" is the system that primarily operates in the coordination of disaster prevention information. While the method of operation as the main system is arbitrary, for example, it may receive event signals from actual equipment, store the event information contained in the event signals, and transmit the event signals containing the stored event information to the linked system.

[0036] Furthermore, a "disaster prevention information infrastructure system operating as a subsystem" is a system that provides backup to ensure that the integration of disaster prevention information is not disrupted in the event of an abnormality in the system that primarily operates in the integration of disaster prevention information. How it operates as a subsystem is arbitrary, but for example, it can receive event signals from actual equipment and store the event information contained in the event signals. However, it does not transmit the event signals indicating the stored event information to the linked information management system. Instead, it remains in active standby mode in preparation for an abnormality in the main system. If an abnormality occurs in the disaster prevention information infrastructure system operating as the main system, it switches over to (is promoted to) the main system and operates as the main system, thereby transmitting event signals to the linked system without interruption and maintaining the integration of disaster prevention information. Note that "active standby" means that the subsystem is in an operational state and on standby, and is a concept that includes "hot standby".

[0037] In this embodiment of a disaster prevention information sharing system, the operational status of the disaster prevention information sharing system can be continuously monitored in a single, continuous manner from the redundant disaster prevention information infrastructure system to the user terminal of the linked information management system, thereby improving the reliability, stability, and trustworthiness of the disaster prevention information sharing system. This is achieved by providing a simulated facility and a test terminal connected to the linked information management system of the linked system. pseudo The system transmits pseudo-event signals in the same format as event signals to both the first communication path, which goes from the equipment to the test terminal via the first disaster prevention information infrastructure system, and the second communication path, which goes from the equipment to the test terminal via the second disaster prevention information infrastructure system, thereby detecting the communication status of the first and second communication paths.

[0038] Here, "simulated equipment" refers to equipment installed in a communication environment that simulates the communication environment from the actual equipment to the first disaster prevention information infrastructure system, and the communication environment from the actual equipment to the second disaster prevention information infrastructure system. pseudo The communication environment for monitoring the operational status of a disaster prevention information sharing system using similar equipment is designed to approximate the communication environment for sharing disaster prevention information from the actual equipment to the linked information management system. pseudo Similar equipment will be installed.

[0039] Furthermore, since it is desirable that the communication environment of the simulated equipment be as close as possible to the communication environment of the actual equipment, if the actual equipment is connected to the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system using wireless communication equipment, such as wireless LAN communication equipment, the simulated equipment will be installed at the same location as the actual equipment and connected to the first and second disaster prevention information infrastructure systems via the wireless communication equipment used in the actual equipment.

[0040] Furthermore, while the configuration of a "pseudo-equipment" is arbitrary as long as it transmits a pseudo-event signal, for example, if the actual equipment is a disaster prevention system equipped with sensors and receivers, the pseudo-equipment would be a pseudo-receiver corresponding to the receiver, or a computer program that functions as a pseudo-receiver by being executed on a computer device.

[0041] Furthermore, "pseudo-event signals" are non-existent signals used to monitor the operating status of the disaster prevention information sharing system. pseudo This is an event signal containing pseudo-event information indicating an event that is assumed to have occurred, and its signal format is the same as an event signal containing event information indicating an event that occurred in actual equipment. pseudo Similar event signals pseudo Similar event information corresponds to the event information of the event signal. Furthermore, the event information included in the event signal includes, for example, event content information indicating the event content, and a unique event ID (event identification information) that makes each signal identifiable. pseudo The same applies to similar event signals. pseudo This includes event content information indicating that it is a similar event, and a unique event ID (event identification information).

[0042] Therefore, pseudo-event signals transmitted from the pseudo-equipment to monitor the operating status of the disaster prevention information linkage system can be processed in the same way as event signals transmitted from actual equipment, and can be processed in the same way as event signals from actual equipment without changing the communication protocols of the first disaster prevention information infrastructure system, the second disaster prevention information infrastructure system, and the linked information management system.

[0043] Furthermore, as part of "detection of the communication status of the first and second communication paths," the communication time required for the pseudo-event signal via the first communication path and the communication time required for the pseudo-event signal via the second communication path are detected. In this case, for the detection of communication time, for example, the average value of the communication time required for the first communication path and the average value of the communication time required for the second communication path over a predetermined number of times are detected.

[0044] Here, the method for detecting the communication time is arbitrary, but for example, a dummy device, pseudo Includes event information that makes each similar event signal identifiable (e.g., including a unique event ID). pseudo Along with sending a similar event signal, pseudoThe transmission time and transmission of the event signal pseudo The event information contained in the event signal is associated with the transmission time information, which is then sent to the test terminal, and the test terminal then... pseudo The reception time when a similar event signal was received and pseudo Detect event information contained in the event signal, pseudo Based on the transmission time and reception time corresponding to the event information detected from the transmission time information received from the similar equipment, the communication time required for the pseudo-event signal via the first communication path and the communication time required for the pseudo-event signal via the second communication path are detected.

[0045] Also, pseudo The transmission time information sent by the equipment is transmitted via a communication path that does not go through the linked information management system. Furthermore, "communication paths different from the first and second communication paths" include, for example, a publicly known email communication path for sending the transmission time information as text information via email.

[0046] Furthermore, the disaster prevention information sharing system determines its operating status based on the detected communication time. While the determination of the operating status of the disaster prevention information sharing system is arbitrary, for example, if the communication time of both the first and second communication paths satisfies the predetermined allowable time conditions, the disaster prevention information sharing system is judged to be normal; if the communication time of the first communication path does not satisfy the allowable time conditions, but the communication time of the second communication path does, the first disaster prevention information infrastructure system is judged to be abnormal; if the communication time of the first communication path satisfies the allowable time conditions, but the communication time of the second communication path does not, the second disaster prevention information infrastructure system is judged to be abnormal; and if the communication time of both the first and second communication paths does not satisfy the allowable time conditions, the disaster prevention information sharing system is judged to be abnormal.

[0047] Here, "determining an anomaly" does not necessarily mean confirming an anomaly in the target system, but rather is a concept that includes judgments such as "there is a high probability of an anomaly" or "there are signs of an impending anomaly."

[0048] Furthermore, if an abnormality is detected in the first disaster prevention information infrastructure system, which is operating as the main system, or in the second disaster prevention information infrastructure system belonging to the second communication path, the disaster prevention information infrastructure system operating as the main system will be shut down, and the disaster prevention information infrastructure system operating as a subsystem will be switched to (promoted) as the main system and put into operation, thereby preventing any interruption in the communication of disaster prevention information.

[0049] Furthermore, the "user terminal" displays event information contained in the signal based on the event signal, and the test terminal is a terminal corresponding to the type of user terminal that is placed in the same communication environment as the user terminal. pseudo The communication status of the first and second communication paths from the equipment to itself is displayed. Here, if the user terminal is, for example, a mobile device such as a smartphone or tablet, or a personal computer, the same mobile device or personal computer as the user terminal is prepared as a test terminal.

[0050] The following describes a specific embodiment. In the specific embodiment shown below, the "actual equipment" is a "fire alarm system consisting of fire detectors and receivers," the "first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system" is a "system constructed by duplicating a disaster prevention information infrastructure that functions as a disaster prevention information platform using a cloud server that can communicate via a general-purpose public network such as the Internet," and the "cooperation partner system" is a "system comprising a cooperation partner information management system that communicates with the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system, a user terminal, a test terminal, and a monitoring terminal that determines the operating status of the disaster prevention information cooperation system based on the detected communication time."

[0052] [a. Disaster Prevention Information Sharing System] A disaster prevention information sharing system according to the present invention will be described. In this description, refer to Figure 1, which shows an embodiment of the disaster prevention information sharing system.

[0053] As shown in Figure 1, the disaster prevention information sharing system, in normal operation, is configured to share disaster prevention information and includes a fire alarm system 10 that functions as actual equipment, a redundant first disaster prevention information infrastructure system 12 (12-1) and a second disaster prevention information infrastructure system 12 (12-2), a linked information management system 14 provided by the linked system, and a user terminal 16.

[0054] Furthermore, the fire alarm system 10 is connected to the redundant first disaster prevention information infrastructure system 12(12-1) and second disaster prevention information infrastructure system 12(12-2) via the public general-purpose communication network 18. One of the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2) operates as the main system, and the other operates as a subsystem. Here, we will explain the initial settings assuming that the first disaster prevention information infrastructure system 12(12-1) operates as the main system and the second disaster prevention information infrastructure system 12(12-2) operates as a subsystem.

[0055] The redundant first disaster prevention information infrastructure system 12(12-1) and second disaster prevention information infrastructure system 12(12-2) are configured such that, in order to avoid simultaneous failures of the equipment and devices used to construct the systems, such as when they are simultaneously affected by earthquakes or floods, the equipment and devices for constructing the systems are installed in geographically separated remote locations. For example, the equipment and devices for constructing one system are installed in the Tokyo area, and the equipment and devices for constructing the other system are installed in the Osaka area. Furthermore, the configuration of the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2) is at the discretion of the system, as long as the linkage of disaster prevention information is not interrupted.

[0056] The first disaster prevention information infrastructure system 12(12-1), which operates as the main system, is connected to the linked information management system 14 via the public general-purpose communication network 18. The second disaster prevention information infrastructure system 12(12-2), which operates as a subsystem, is in a standby state (active standby state) in preparation for any abnormality in the first disaster prevention information infrastructure system 12(12-1), which operates as the main system, and is not connected to the linked information management system 14 via the public general-purpose communication network 18.

[0057] Furthermore, the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2) are connected to each other via a public general-purpose communication network 18. For the purpose of monitoring their operational status, they periodically transmit operational status signals to each other. If one operational status signal is received from the other, the other is judged to be normal. If an operational status signal is not received from the other for a predetermined number of consecutive times, the other is judged to be abnormal. If the subsystem determines that the main system is abnormal, the subsystem is promoted to the main system and performs a degraded operation to maintain its function as a disaster prevention information infrastructure system.

[0058] The public general-purpose communication network 18 is a communication network using lines shared and used by an unspecified number of users. For example, it is a communication network that enables general users who have applied to connect and use various devices and equipment such as computers by setting a login ID and password. It is a known communication network composed of one or more communication networks such as the Internet, wired LAN, wireless LAN, and mobile phone network.

[0059] The linked information management system 14 is a system owned by an entity such as a company, for example, in order to receive disaster prevention information linked via a general-purpose public network 18. It communicates with user terminals 16 owned by employees and other related parties belonging to that entity via a dedicated communication network 20 for that entity in order to provide various information, including necessary disaster prevention information, to the user terminals 16. The dedicated communication network 20 is a communication network such as an intranet that issues login IDs and passwords only to employees and other related parties of the entity that owns the linked information management system 14, making it available to a limited number of people. For example, it is a publicly known communication network such as a campus LAN.

[0060] Furthermore, the disaster prevention information sharing system is equipped with a simulated fire alarm system 100 that functions as a simulated system in response to the fire alarm system 10, in order to monitor the operating status of the disaster prevention information sharing system during normal operation. The linked system is equipped with a test terminal 110 and a monitoring terminal 112 in response to the user terminal 16.

[0061] Furthermore, each of the fire alarm equipment 10, the first disaster prevention information infrastructure system 12(12-1), the second disaster prevention information infrastructure system 12(12-2), the linked information management system 14, the user terminal 16, the simulated fire alarm equipment 100, the test terminal 110, and the monitoring terminal 112, all of which are installed in the disaster prevention information linkage system, are synchronized in time by communication with a known time server or the like in order to match time information with each other.

[0062] [b. Fire alarm system] Next, the fire alarm system 10 will be described. As shown in Figure 1, the fire alarm system 10 comprises a receiver 22, fire detectors 24, and a communication unit 26. The fire alarm system 10 is installed in facilities such as buildings and offices of business entities that are subject to monitoring, such as companies that own the first disaster prevention information infrastructure system 12 (12-1) and the second disaster prevention information infrastructure system 12 (12-2). The fire detectors 24 are installed in the monitoring area of ​​the monitored area and detect fires occurring in the monitoring area and transmit a fire signal to the receiver 22. Here, "monitoring area" refers to the area in which the fire alarm system monitors for fires, and when the monitoring target is a facility, it is a concept that includes any area within the facility, such as rooms, corridors, stairs, elevator halls, etc., or outside the building, such as a parking lot.

[0063] The receiver 22 receives a fire signal from the fire detector 24, detects the occurrence of a fire alarm or malfunction, and notifies the malfunction alarm, for example, by sound and display. It also generates event content information indicating the event such as a fire or malfunction, and an event ID to uniquely identify the event content information, and outputs an event signal containing the event content information and event ID to the communication unit 26. In the following description, the event signal transmitted from the fire alarm system 10 (receiver 22) may be referred to as the "source event signal".

[0064] Here, event information includes the event content and the location where the event occurred. The event content indicates the type of event that occurred and includes fire, fire recovery, malfunction, etc. The location where the event occurred is, for example, the location where the fire detector 24 that detected the fire was installed, and in order to allow the user terminal 16 of the linked device to easily understand the location, a district name such as "Room 01 on the 1st floor" or "Elevator Hall on the 1st floor" is used. If fire alarm equipment is installed to correspond to multiple monitoring targets, the location of each fire alarm equipment may be included in the event location, or the location of each fire alarm equipment may be used as the event location without including information on the location of the fire detector 24.

[0065] The communication unit 26 transmits the source event signal output from the receiver 22 to two locations, the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2), via the public general-purpose communication network 18. The configuration and functions of the communication unit 26 are arbitrary, but for example, a wireless LAN communication device such as a Wi-Fi® communication device with router functionality is provided, and a known communication method known as multicast or broadcast communication is used to transmit event signals to two locations simultaneously.

[0066] [c. Dual-redundant disaster prevention information infrastructure system] Next, we will describe the redundant disaster prevention information infrastructure system. As shown in Figure 1, the first disaster prevention information infrastructure system 12(12-1) comprises a control unit 28(28-1), a communication unit 30(30-1), a storage unit 32(32-1), and an operation display unit 34(34-1).

[0067] The first disaster prevention information infrastructure system 12(12-1) is specifically constructed using a computer device equipped with a CPU, memory, computer circuits with various input / output ports, external storage devices such as hard disks, a keyboard, a display, etc., and functions as a disaster prevention information infrastructure for managing disaster prevention information. For example, it is a disaster prevention information platform that functions as a disaster prevention information infrastructure for managing disaster prevention information, built on a cloud server.

[0068] Furthermore, when the control unit 28(28-1) receives a source event signal transmitted from the fire alarm system 10 via the communication unit 30(30-1), it performs control to store the event content information and event ID contained in the source event signal in the storage unit 32(32-1) in association with time information and accumulate it as event history information.

[0069] Furthermore, the control unit 28(28-1) of the first disaster prevention information infrastructure system 12(12-1), which is operating as the main system by default, receives a source event signal from the fire alarm equipment 10, generates an event signal including event content information and an event ID from the event history information stored in the storage unit 32(32-1), and controls the communication unit 30(30-1) to transmit it to the linked information management system 14.

[0070] Furthermore, the second disaster prevention information infrastructure system 12(12-2) consists of a control unit 28(28-2), a communication unit 30(30-2), a storage unit 32(32-2), and an operation display unit 34(34-2), and is basically the same as the first disaster prevention information infrastructure system 12(12-1), so its explanation will be omitted.

[0071] One difference is that the control unit 28(28-2) of the second disaster prevention information infrastructure system 12(12-1), which operates as a subsystem by default, does not perform the control to receive the source event signal from the fire alarm equipment 10, generate an event signal including event content information and an event ID from the event history information stored in the storage unit 32(32-1), and transmit it to the linked information management system 14.

[0072] Furthermore, the control units 28(28-1) and 28(28-2) each transmit a live signal to the other, for example, at predetermined intervals. If a live signal is received from the other unit, the other unit is judged to be normal. However, if a live signal is not received for a predetermined number of consecutive times, the control unit judges that the other unit is abnormal and performs a predetermined degraded control. Degraded control is a control method in which a subsystem is promoted to the main system and operates as the main system.

[0073] In the following explanation, event signals transmitted from the first disaster prevention information infrastructure system 12(12-1) and the first disaster prevention information infrastructure system 12(12-2) may be referred to as "linked event signals."

[0074] [d. Partner Information Management System] Next, the linked information management system will be described. As shown in Figure 1, the linked information management system 14 comprises a control unit 36, a communication unit 38, a storage unit 40, and an operation display unit 42. Specifically, it is constructed using a computer device equipped with a CPU, memory, a computer circuit with various input / output ports, an external storage device such as a hard disk, a keyboard, a display, etc., and has the function of managing linked disaster prevention information. For example, it has the function of managing information operations for all aspects of corporate business as a server, and the function of managing linked disaster prevention information is included as part of that function.

[0075] The user terminal 16 connects to the linked information management system 14 via a dedicated communication network 20. The type and function of the user terminal 16 are arbitrary, but include, for example, tablet devices, smartphones and other mobile devices, and personal computers.

[0076] If the server that processes the linked information management system 14, the user terminal 16, and the test terminal 110 are located within the same building, it is preferable that the dedicated communication network 20 be configured using a LAN (Local Area Network) located within that building.

[0077] However, considering cases where the linked information management system 14 provides services to multiple buildings, or where the linked information management system 14 is not located in the same building as the user terminal 16 and the test terminal 110, it is also possible to use a public general-purpose communication network for at least a portion of the dedicated communication network 20.

[0078] [e. Integration of disaster prevention information] Next, we will explain the operation of the disaster information sharing system. For this explanation, please refer to Figure 2, which shows the communication path in the sharing of disaster information, and Figure 3, which is a time chart showing the operation of the disaster information sharing system.

[0079] (e1. Communication path) First, let's explain the communication path for the sharing of disaster prevention information. As shown in Figure 2, on the side of the first disaster prevention information infrastructure system 12(12-1), which is operating as the main system, a communication path is formed from the fire alarm equipment 10 to the first disaster prevention information infrastructure system 12(12-1) and the linked information management system 14, and then to the user terminal 16. Through this communication path, event information generated by the fire alarm equipment 10 and an event signal including its event ID are transmitted to the user terminal 16, where the event information is received and displayed.

[0080] In contrast, on the side of the second disaster prevention information infrastructure system 12(12-2), which operates as a subsystem, a communication path is formed from the fire alarm equipment 10 to the second disaster prevention information infrastructure system 12(12-2). The same event signal that was sent to the first disaster prevention information infrastructure system 12(12-1) is also sent to the second disaster prevention information infrastructure system 12(12-2) via this communication path. However, it is only received by the second disaster prevention information infrastructure system 12(12-2) and stored as event history information, and is not transmitted to the user terminals 16 via the linked information management system 14.

[0081] (e2.2 Coordination of redundant disaster prevention information) Next, we will explain the coordinated operation of the redundant disaster prevention information. As shown in Figure 3, the first disaster prevention information infrastructure system 12(12-1) is set as the main system (step S1), and the second disaster prevention information infrastructure system 12(12-2) is set as the subsystem (step S2), and both are operating. In this case, the operation is controlled by the control units 28(28-1) and 28(28-2) of the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2).

[0082] An event occurs (step S3), fire alarm system 1 0 The system transmits the linked event signal to the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2) (step S4).

[0083] Here, the source event signal includes event content information and an event ID. For example, if a fire occurs in the elevator hall on the first floor of the facility being monitored as an event, it would include event content information such as "Fire occurred in the elevator hall on the first floor at XX:XX" and an event ID such as "ID001" to uniquely identify that event content information.

[0084] The first disaster prevention information infrastructure system 12(12-1), upon receiving the source event signal, acquires the event content information and event ID contained in the received source event signal, correlates the acquired event content information and event ID with time information indicating the time of reception, and stores them in the storage unit 32(32-1) as event history information. Subsequently, the first disaster prevention information infrastructure system 12(12-1) generates a destination event signal containing the event content information and event ID from the stored event history information and transmits it to the destination information management system 14, causing the user terminal 16 to receive and display the event information (steps S5, S7, S8).

[0085] On the other hand, the second disaster prevention information infrastructure system 12 (12-2), which receives the source event signal, acquires the event content information and event ID contained in the received source event signal, associates the acquired event content information and event ID with time information indicating the time of reception, and stores and accumulates them as event history information in the storage unit 32 (32-2). However, it does not generate a destination event signal and send it to the destination information management server 14 (step S6).

[0086] Here, we will explain the monitoring operations of the other party by the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2).

[0087] The first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2) repeatedly transmit a live signal to each other at a predetermined interval, for example, every minute, in order to determine whether the other party's operation is normal or abnormal. If the live signal is continuously received, it is determined that the other party's system is operating normally. Conversely, if the live signal is not received for a predetermined number of consecutive times, it is determined that the other party's operation is abnormal.

[0088] If an abnormality occurs in the first disaster prevention information infrastructure system 12(12-1), which is operating as the main system (step S9), the second disaster prevention information infrastructure system 12(12-2), which is operating as a subsystem, will no longer receive a live signal from the first disaster prevention information infrastructure system 12(12-1), and will therefore determine that there is an abnormality in the main system (step S10) and perform degradation control.

[0089] Specifically, as part of the degraded control, the second disaster prevention information infrastructure system 12(12-2) sends a promotion request to the first disaster prevention information infrastructure system 12(12-1) to request approval to operate as the main system. If the main system does not respond within a predetermined time, or if it responds with approval, the system is promoted to the main system and starts operating as the main system (step S11).

[0090] In this case, there is a possibility that no linked event signals were sent from the first disaster prevention information infrastructure system 12(12-1), which was operating as the main system, to the linked information management system 14 between the time an abnormality occurred in the first disaster prevention information infrastructure system 12(12-1) and the time the second disaster prevention information infrastructure system 12(12-2) started operating as the main system. Therefore, the second disaster prevention information infrastructure system 12(12-2) identifies the event content information and event ID included in the linked source event signals received between the time it stopped receiving the health signal and the time it started operating as the main system, from the event history information stored in the storage unit 32(32-1), generates a linked event signal including the identified event content information and event ID, sends it to the linked information management system 14, and displays the event information on the user terminal 16.

[0091] After the second disaster prevention information infrastructure system 12(12-2) is promoted to the main system, an event occurs (step S13) and a source event signal is transmitted from the fire alarm equipment 10 (step S14). The second disaster prevention information infrastructure system 12(12-2) acquires the event content information and event ID contained in the received source event signal, associates the acquired event content information and event ID with time information indicating the time of reception, stores and accumulates them as event history information in the storage unit 32(32-2), generates a destination event signal including the event content information and event ID and transmits it to the destination information management system 14, and displays the event information on the user terminal 16 (steps S15, S16, S17).

[0092] Meanwhile, the first disaster prevention information infrastructure system 12(12-1) where the abnormality occurred will stop its coordinated operation and perform an abnormality repair operation to fix the abnormality (step S12). If the system cannot be restored by its own abnormality repair operation, it will be restored by necessary repairs performed by a human.

[0093] When the first disaster prevention information infrastructure system 12(12-1) is restored by abnormal repair operation or repair, etc. (step S18), the event history information corresponding to the linked event signals transmitted from the fire alarm equipment 10 between the time the second disaster prevention information infrastructure system 12(12-2) stopped receiving the live signal and the time it starts receiving the live signal again may not be stored in the storage unit 32(32-1) of the first disaster prevention information infrastructure system 12(12-1). Therefore, the second disaster prevention information infrastructure system 12(12-2) identifies the event history information that may not be stored in the first disaster prevention information infrastructure system 12(12-1), generates an event signal including the identified event content information and event ID, and transmits it to the first disaster prevention information infrastructure system 12(12-1), performing storage synchronization (mirroring) to match the event history information of both systems (steps S19, S20).

[0094] After the event history information is synchronized, the first disaster prevention information infrastructure system 12 (12-1) is demoted to a subsystem and starts cooperative operation (step S21).

[0095] In other words, thereafter, the first disaster prevention information infrastructure system 12(12-1) operates as a subsystem and the second disaster prevention information infrastructure system 12(12-2) operates as the main system. When an event occurs and a source event signal is transmitted from the receiver 22 of the fire alarm equipment 10, the second disaster prevention information infrastructure system 12(12-2) stores event history information in the storage unit 32(32-2) based on the received source event signal, and generates a destination event signal including event content information and an event ID, which is sent to the destination information management system 14. The user terminal 16 receives and displays the event information. The first disaster prevention information infrastructure system 12(12-1) stores event history information in the storage unit 32(32-1) based on the received source event signal, but does not perform the operation to send it to the destination information management server 14 (steps S22-S27).

[0096] [f. Monitoring the system's operating status] Next, we will explain the monitoring operation for monitoring the operating status of the disaster prevention information sharing system. To monitor the operating status of the disaster prevention information sharing system, as shown in Figure 1, the disaster prevention information sharing system is equipped with a simulated fire alarm system 100 that functions as a simulated system corresponding to the fire alarm system 10, and the linked system is equipped with a test terminal 110 and a monitoring terminal 112 corresponding to the user terminal 16.

[0097] (f1. Simulated fire alarm system) First, let me explain the simulated fire alarm system. The simulated fire alarm system 100 is installed in conjunction with the actual fire alarm system 10 and includes a simulated receiver 102 and a transmitter 104.

[0098] The pseudo-receiver 102 has a function to sequentially output a first pseudo-event signal and a second pseudo-event signal to the communication unit 104 at predetermined system monitoring timings, for example, every minute, in order to monitor the operating status of the system. Here, the first pseudo-event signal is a signal in the same format as the event signal transmitted from the fire alarm system 10, which includes event content information and an event ID to uniquely identify the event content information. The event content information includes information indicating that it is a "pseudo-event," and the event ID is a first event ID to uniquely identify the pseudo-event. The second pseudo-event signal is similar to the first pseudo-event signal, but differs in that it includes a second event ID as the event ID.

[0099] Furthermore, the pseudo-receiver 102 detects and stores the first transmission time when it transmits the first pseudo-event signal, and detects and stores the second transmission time when it transmits the second pseudo-event signal. In addition, at a predetermined timing after transmitting the first pseudo-event signal and the second pseudo-event signal, the pseudo-receiver 102 generates transmission time information including information associating the first event ID with the first transmission time, and information associating the second transmission time with the second event ID, and controls the transmission of this transmission time information to the test terminal 110 via a communication path that does not go through the first disaster prevention information infrastructure system 12(12-1), the second disaster prevention information infrastructure system 12(12-2), and the linked information management system 14. As for the transmission of the transmission time information, for example, the pseudo-receiver 102 creates an email with the transmission time information attached as text information and controls the transmission of this transmission time information to the test terminal 110 via the email communication path.

[0100] Furthermore, the pseudo-receiver 102 is not connected to a fire detector 24, and does not have the function to monitor or notify about events such as fires, and it simulates an event occurring. pseudo The system consists of a computer circuit whose function of transmitting a pseudo-event signal is realized through the execution of a program. Alternatively, the pseudo-receiver 102 can be described as a program that realizes this function through computer execution.

[0101] The communication unit 104 transmits the first pseudo-event signal output from the pseudo-receiver 102 to the first disaster prevention information infrastructure system 12 (12-1), and then transmits the second pseudo-event signal output from the pseudo-receiver 102 to the second disaster prevention information infrastructure system 12 (12-2). The configuration and functions of the communication unit 104 are arbitrary, but ensuring a communication environment as close as possible to the communication unit 26 installed in the actual fire alarm system 10 will improve the accuracy of monitoring the overall system communication status using pseudo-event signals. Therefore, the same communication device as the communication unit 26, such as a wireless LAN communication device such as a Wi-Fi® communication device with router functionality, is provided, and known communication known as unicast is performed to transmit event signals to a specific location. Note that the communication unit 26 and the communication unit 104 may be configured as a single communication unit.

[0102] (f2. First communication path and second communication path) Next, we will describe the first and second communication paths used for monitoring the system's operating status. This description will refer to Figure 4, which shows the communication paths for monitoring the system's operating status. Figure 4(A) shows the first communication path, and Figure 4(B) shows the second communication path.

[0103] As shown in Figure 4(A), the first communication path is a communication path that transmits the first pseudo-event signal sent from the pseudo-fire alarm system 100 to the test terminal 110 via the first disaster prevention information infrastructure system 12(12-1) and the linked information management system 14. Also, as shown in Figure 4(B), the second communication path is a communication path that transmits the second pseudo-event signal sent from the pseudo-fire alarm system 100 to the test terminal 110 via the second disaster prevention information infrastructure system 12(12-2) and the linked information management system 14.

[0104] Here, if the system operating as the main system is designated as the first disaster prevention information infrastructure system 12(12-1) and the system operating as a subsystem is designated as the second disaster prevention information infrastructure system 12(12-2), then the first disaster prevention information infrastructure system 12(12-1) stores event content information and event ID as event history information based on the source event signal received from the fire alarm equipment 10, and generates a destination event signal including the event content information and event ID, which is sent to the destination information management system 14 to receive and display the event information on the user terminal 16. Similarly, when a first pseudo-event signal is transmitted from the pseudo-fire alarm equipment 100, the system receives the event signal, stores event history information, and transmits the event signal, so its operation is no different from that of the main system. pseudo It will continue to operate even when receiving a similar event signal.

[0105] Therefore, when the first disaster prevention information infrastructure system 12(12-1) receives the first pseudo-event signal, it stores event content information indicating a "pseudo-event" and the first event ID as event history information based on the first pseudo-event signal, and generates a first pseudo-event signal including the event content information and the first event ID, and transmits it to the test terminal 110 via the linked information management system 14.

[0106] In contrast, the second disaster prevention information infrastructure system 12 (12-2) stores event content information and event ID as event history information based on the source event signal received from the fire alarm equipment 10, but it does not generate a destination event signal and send it to the destination information management system 14. Therefore, in its subsystem operation, it cannot send the second pseudo-event signal to the destination information management system 14.

[0107] Therefore, the second disaster prevention information infrastructure system 12(12-2), which operates as a subsystem, receives the second pseudo-event signal, and the event content information and the second pseudoWhen storing the pseudo-event ID as event history information, the system identifies that the event content information contained in the second pseudo-event signal is a "pseudo-event," temporarily deactivates its subsystem function, generates a second pseudo-event signal containing event content information and a second pseudo-event ID that indicate the same "pseudo-event" as the received second pseudo-event signal, and modifies its operation to transmit it to the test terminal 110 via the linked information management system 14.

[0108] Furthermore, the linked disaster prevention management system 14, upon receiving a first pseudo-event signal or a second pseudo-event signal, performs control to transmit the same first pseudo-event signal or second pseudo-event signal to a test terminal 110 that has been registered as a destination in advance. 。

[0109] (f3. Test terminal) Next, we will describe the test terminal 110, which is provided in conjunction with the user terminal 16 that is connected to the linked information management system 14. In this description, please refer to Figure 5, which shows the communication information, including the communication duration detected by the test terminal 110, in list format.

[0110] The test terminal 110 detects the communication status of the first pseudo-event signal received via the first communication path 44 shown in Figure 4, and the communication status of the second pseudo-event signal received via the second communication path 46. As communication status, it detects, for example, the first communication time for the first pseudo-event signal and the second communication time for the second pseudo-event signal.

[0111] To detect the communication time, the test terminal 110 records the first reception time when it receives the first pseudo-event signal via the first communication path 44 in Figure 4(A) as the first reception time of the received signal. pseudo The first event ID included in the event signal is detected together with the received first event ID from the transmission time information received via the mail communication path 48. pseudoThe first transmission time corresponding to the first event ID contained in the event signal is detected, and from the detected first reception time and first transmission time, (First reception time) - (First transmission time) The first communication time for the first communication path 44 is detected.

[0112] Furthermore, when the test terminal 110 receives the second pseudo-event signal via the second communication path 46 in Figure 4(B), the second reception time is recorded as the second reception time of the received signal. pseudo The second event ID included in the event signal is detected together with the received second event ID from the transmission time information received via the mail communication path 48. pseudo The second transmission time corresponding to the second event ID contained in the event signal is detected, and from the detected second reception time and second transmission time, (Second reception time) - (Second transmission time) The second communication time for the second communication path 46 is detected. In this embodiment, the average communication time is detected as the average value of the communication times over a predetermined number of times.

[0113] Figure 5 shows an example of communication information 50, which includes the communication duration detected by the test terminal 110. The communication information 50 includes the first transmission time and first reception time detected in accordance with the first event ID, and the first communication duration and its average first communication duration, Tab1, detected based on these.

[0114] The same applies to the second communication path, where the communication information 50 includes the second transmission time and second reception time detected in accordance with the second event ID, and the second communication duration and its average second communication duration, Tab2, detected based on these.

[0115] (f4. Determining the system's operating status based on communication time) Next, we will explain how the system's operating status is determined based on the communication time. In this explanation, please refer to Figure 6, which shows the system's operating status determination information 52 determined based on the communication time.

[0116] In this embodiment, the communication information 50 detected by the test terminal 110 shown in Figure 1 is transmitted, for example, to a monitoring terminal 112 via a general-purpose public network 18, and the monitoring terminal 112 determines the operating status of the system.

[0117] As the operational status of the disaster prevention information sharing system increases with longer communication time, the monitoring terminal 112 compares the first and second communication time with predetermined allowable time conditions to determine whether the operational status of the disaster prevention information sharing system is normal or abnormal. Here, the predetermined allowable time conditions are arbitrary, but for example, if the communication time is less than or equal to the predetermined allowable time, the allowable time condition is met and it is considered acceptable.

[0118] Specifically, as shown in Figure 6, the monitoring terminal 112 determines that there is an abnormality in the first disaster prevention information infrastructure system 12(12-1) if the first communication duration does not meet the predetermined allowable time condition, but the second communication duration does meet the predetermined allowable time condition.

[0119] Furthermore, if the monitoring terminal 112 finds that the first communication time meets the predetermined allowable time conditions, but the second communication path does not meet the predetermined communication time conditions, it will determine that there is an abnormality in the second disaster prevention information infrastructure system 12 (12-2).

[0120] Furthermore, if both the first communication time for the first communication path and the second communication time for the second communication path do not meet the acceptable time conditions, the monitoring terminal 112 will determine that there is an abnormality in the disaster information linkage system without specifically identifying the location of the abnormality, as there are several possible abnormality patterns, such as both the first disaster information infrastructure system 12(12-1) and the second disaster information infrastructure system 12(12-2) being abnormal, or the linked information management system 14 being abnormal. Alternatively, all locations that may be abnormal may be listed as candidates.

[0121] Here, the test terminal 110 is a terminal corresponding to the type of user terminal 16. For example, if a smartphone, tablet, or personal computer is used as the user terminal 16, a smartphone, tablet, or personal computer will be prepared as the test terminal 110, and the first communication time and second communication time will be detected by each test terminal 110. Based on the first communication time and second communication time detected by each test terminal 110, the operating status of the disaster prevention information sharing system will be determined.

[0122] Furthermore, if the monitoring terminal 112 determines that there is an abnormality in either of the disaster prevention information infrastructure systems operating as the main system, the abnormal disaster prevention information infrastructure system will be shut down as the main system, and the other disaster prevention information infrastructure system operating as a subsystem will be promoted to the main system and resume operation.

[0123] [g. Monitoring of the system's operating status] This section describes the monitoring operation of the disaster prevention information sharing system. For this explanation, please refer to Figure 7, which is a time chart showing the monitoring operation of the disaster prevention information sharing system. It will be explained that the first disaster prevention information infrastructure system 12(12-1) operates as the main system, and the second disaster prevention information infrastructure system 12(12-2) operates as a subsystem.

[0124] As shown in Figure 7, during normal operation of the disaster prevention information linkage system, at a predetermined system monitoring timing, the simulated fire alarm equipment 100 first transmits a first simulated event signal to the first disaster prevention information infrastructure system 12(12-1), the first disaster prevention information infrastructure system 12(12-1) receives the first simulated event signal, stores the event content information and first event ID contained in the first simulated event signal as event history information, generates a first simulated event signal containing the same event content information and first event ID, and transmits it to the test terminal 110 via the linked information management system 14, and the test terminal 110 pseudoThe system receives and displays pseudo-event information, and detects the first display time when the first pseudo-event signal was received (steps S101 to S105).

[0125] Furthermore, when the simulated fire alarm system 100 transmits a first simulated event signal, it detects the first transmission time when the first simulated event signal was transmitted, and also detects the first transmission time when the first simulated event signal was transmitted. pseudo The first event ID and first transmission time of the event signal are associated (steps S106, S107).

[0126] Next, the simulated fire alarm system 100 transmits a second simulated event signal to the second disaster prevention information infrastructure system 12(12-2), and the second disaster prevention information infrastructure system 12(12-2) receives the second simulated event signal, stores the event content information and second event ID contained in the second simulated event signal as event history information, temporarily deactivates the subsystem operation based on the identification of the event content information, generates a second simulated event signal containing the same event content information and second event ID, and transmits it to the test terminal 110 via the linked information management system 14, and the test terminal 110 pseudo The system receives and displays pseudo-event information to detect the second reception display time when the second pseudo-event signal was received (steps S108-S112).

[0127] Furthermore, when the simulated fire alarm system 100 transmits a second simulated event signal, it detects the second transmission time when the second simulated event signal was transmitted, and also detects the second transmission time when the second event signal was transmitted. pseudo The first event ID and the second transmission time of the similar event signal are associated (steps S113, S114).

[0128] Next, the simulated fire alarm system 100 generates text data of transmission time information, including information associating a first event ID with a first transmission time, and information associating a second event ID with a second transmission time, and sends it to the test terminal 110 via email attachment. The test terminal 110 receives the email from the simulated receiver 102, detects the first communication time for the first communication path and the second communication time for the second communication path, and sends the detected communication information 50 to the monitoring terminal 112 to determine the operating status of the system (steps S115 to S119). Note that the first and second communication times are detected as the average value of a predetermined number of communication times, so the processing in steps S101 to S116 is performed multiple times. That process has been omitted.

[0129] Then, in response to the judgment result of the monitored terminal 112, the first disaster prevention information infrastructure system 12(12-1) and the second disaster prevention information infrastructure system 12(12-2) perform processing such as promoting a subsystem to the main system and starting operation (steps S120, S121).

[0130] [h. Variations of the present invention] Finally, modifications of the disaster prevention information sharing system according to the present invention will be described. In addition to the embodiments described above, the disaster prevention information sharing system of the present invention includes the following modifications.

[0131] (Coordination of multiple physical facilities) The above embodiment uses a disaster prevention information linkage system as an example, which links disaster prevention information from one fire alarm system to a user terminal of a linked information management system of one via a redundant first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system. However, it may also be a disaster prevention information linkage system which links fire alarm systems of multiple different business entities to user terminals of linked information management systems of multiple different business entities via a redundant first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system.

[0132] (Determining the system's operating status) In the above embodiment, the system's operating state is determined by detecting the communication time required for the first and second communication paths using a pseudo-event signal as the communication state. However, the detection of the communication state is not limited to this and is arbitrary. For example, the system's operating state may be determined by detecting the communication speed (bps) of the first and second communication paths using a pseudo-event signal. Specifically, since the amount of data (number of bits) of the pseudo-event signal is uniquely determined, the system's operating state is determined by detecting the communication speed (bps) based on the detected communication time and the amount of communication data. In addition to communication time and communication speed, the system's operating state may also be determined by detecting, for example, the error rate.

[0133] (Monitoring the system's operating status) In the above embodiment, the system's operating status is monitored by the test terminal 110 detecting the communication time as a communication status and the monitoring terminal 112 determining the system's operating status based on the detection result. However, this does not prevent the detection of the communication status from being performed by a terminal other than the test terminal 110, or the determination of the system's operating status from being performed by a terminal other than the monitoring terminal 112. For example, the system's operating status may be determined by the test terminal 110 without a monitoring terminal 112, or the linked information management system 14 may be configured to perform these processes collectively, and neither the test terminal 110 nor the monitoring terminal 112 may be provided. Furthermore, the test terminal 110 may also be configured to serve as the monitoring terminal 112.

[0134] (others) Furthermore, the present invention includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values ​​shown in the above embodiments. [Explanation of Symbols]
