Description

The present invention is a disaster prevention system that manages various kinds of disaster prevention information regarding fires, failures, earthquakes, floods, etc. monitored in disaster prevention equipment using a redundant disaster prevention information infrastructure system, and links the disaster prevention information to a linked system. Regarding information collaboration systems.

Conventionally, secondary use of disaster prevention information regarding fires, failures, etc. monitored by fire alarm equipment, which is a type of disaster prevention equipment, is received and displayed on devices other than fire alarm equipment, such as user terminals, etc. Limitations are limited to transfer coordination using contact transfer signals and intra-facility coordination using BAS standard protocols (BACnet, etc.) that unify communication specifications for air conditioning equipment, lighting equipment, electrical equipment, crime prevention/disaster prevention equipment, etc. within the facility. The mainstream is to use disaster prevention information within designated areas, and the collaboration of disaster prevention information using public lines such as the Internet has been avoided because it is difficult to guarantee its reliability.

Therefore, the purpose of linking disaster prevention information using public lines is to improve stable operation and resilience in the event of a failure, and to guarantee reliability. The disaster prevention information infrastructure built as a platform on the server is duplicated, so that even if an abnormality occurs in one disaster prevention information infrastructure system, the disaster prevention information similarly managed by the other disaster prevention information infrastructure system will be sent to the linked system. A disaster prevention information sharing system is being considered.

However, abnormality monitoring of a redundant disaster prevention information infrastructure system on a cloud server is mainly performed using software on the cloud server, and there is a problem with the real-time nature of the monitoring.

In addition, when linking disaster prevention information using public lines, the link destination may be the system of another business entity, and the specifications are significantly different from the disaster prevention information infrastructure system of the own business entity built on a cloud server. It is difficult to monitor abnormalities using cloud server software, including the information management system of the business entity with which it is linked.

Furthermore, since fires and disasters do not occur frequently, event signals containing disaster prevention information are not always sent from each disaster prevention equipment, and during normal operation, each disaster prevention equipment uses event signals to transmit disaster prevention information. It is difficult to check the communication status from the information infrastructure system to the partner system all at once.

The present invention makes it possible to monitor the operating status of a disaster prevention information coordination system from actual equipment to a coordination destination system via a redundant disaster prevention information infrastructure system during normal operation, thereby ensuring reliability and stability in coordination of disaster prevention information. The purpose is to provide a disaster prevention information coordination system that can improve performance and reliability.

(Communication route for transmission time information)
The transmission time information is transmitted through a communication route that does not go through the cooperation destination information management system.

(Judgment of system operating status)
If both the communication time required for the first communication route and the communication time required for the second communication route satisfy a predetermined allowable time condition, it is determined that the disaster prevention information coordination system is normal;
If the communication time required for the first communication path does not satisfy the permissible time condition and the communication time required for the second communication path satisfies the permissible time condition, it is determined that there is an abnormality in the first disaster prevention information infrastructure system,

(Effects of disaster prevention information sharing system)
The present invention transmits an event signal containing event information indicating a predetermined event occurring in an actual facility that performs disaster prevention monitoring to each of a duplicated first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system, and An event signal containing event information is transmitted from at least one of the first disaster prevention information infrastructure system or the second disaster prevention information infrastructure system to the cooperation partner system, and the cooperation partner system receives the event signal and transmits the event signal to the user terminal based on the event signal. A disaster prevention information collaboration system that includes a linked information management system that transmits signals to user terminals, and includes a communication environment from actual equipment to the first disaster prevention information infrastructure system, and communication from the actual equipment to the second disaster prevention information infrastructure system. Equipped with a simulated equipment installed in a communication environment that simulates the environment, and a test terminal connected to the linked information management system in the linked system, the test terminal is connected to the linked system from the simulated equipment via the first disaster prevention information infrastructure system. A pseudo-event signal in the same signal format as the event signal is transmitted to each of the first communication path leading to the test terminal and the second communication path leading to the test terminal via the second disaster prevention information infrastructure system, and Since the communication status of two communication paths is detected, during normal operation, tests can be performed via the redundant disaster prevention information infrastructure system using pseudo event signals from the pseudo equipment, without transmitting event signals from the actual equipment. It is possible to detect the communication status of the disaster prevention information coordination system up to the terminal, and it is possible to constantly monitor whether the operation status of the disaster prevention information coordination system is normal or abnormal from the communication status, thereby increasing the reliability, stability, and reliability of disaster prevention information coordination. can be improved.

In addition, even if one of the redundant disaster prevention information infrastructure systems is in standby mode and does not send an event signal to the linked system, a pseudo event signal from the pseudo equipment can be used instead of using an event signal. In order to detect the communication status of the disaster prevention information collaboration system, we constantly monitor whether the operating status of the disaster prevention information collaboration system is normal or abnormal, including the disaster prevention information infrastructure system that is in a standby state without sending event signals. possible.

(Effects of monitoring communication time required)
Furthermore, the communication state of the first communication path and the second communication path is detected by detecting the communication time required for the pseudo event signal through the first communication path and the communication time required for the pseudo event signal through the second communication path. Based on the communication time required for the detected first communication path and second communication path, predict abnormalities before they result in failures (failures) due to performance deterioration of the disaster prevention information coordination system, equipment, devices, etc. that make up the system. is possible.

(Effect of detection of communication time required)
The pseudo-event signal transmits pseudo-event signals including event information that makes each of the pseudo-event signals identifiable, and also matches the transmission time of the pseudo-event signal with the event information included in the transmitted pseudo-event signal. The transmission time information is sent to the test terminal, the test terminal detects the reception time when the pseudo event signal was received and the event information included in the pseudo event signal, and responds to the event information detected from the transmission time information received from the pseudo equipment. Based on the transmission time and the detected reception time, the communication time required for the pseudo event signal through the first communication path and the communication time required for the pseudo event signal through the second communication path are detected. For the pseudo event signals sent via each of the communication path and the second communication path, the required communication time is individually detected from the sending time of the pseudo event signal from the pseudo equipment and the receiving time of the pseudo event signal at the test terminal. This makes it possible to accurately determine whether the operating state of the disaster prevention information coordination system is normal or abnormal.

(Effect of communication route for transmission time information)
In addition, since the transmission time information is sent through a communication route that does not go through the collaboration partner information management system, even if the collaboration partner information management system uses a communication protocol that does not send transmission time information to the user terminal, the test The test terminal can acquire transmission time information regardless of the configuration of the linked system, such as the terminal being able to acquire transmission time information.

(Effects of determining system operating status)
In addition, if both the communication time required for the first communication route and the communication time required for the second communication route satisfy a predetermined allowable time condition, it is determined that the disaster prevention information coordination system is normal, and the communication time for the first communication route is determined to be normal. If the required time does not satisfy the allowable time condition, but the communication time required for the second communication route satisfies the allowable time condition, it is determined that there is an abnormality in the first disaster prevention information infrastructure system, and the communication time required for the first communication route is determined to be abnormal. satisfies the allowable time condition, and if the communication time required for the second communication path does not satisfy the allowable time condition, it is determined that the second disaster prevention information infrastructure system is abnormal, and the communication of the first communication path and the second communication path is terminated. If both of the required times do not satisfy the allowable time conditions, it is determined that there is an abnormality in the disaster prevention information sharing system. Therefore, the communication required time of the pseudo event signal on either the first communication route or the second communication route is If it is within the allowable time, it can be confirmed that the disaster prevention information coordination system and the devices and devices that make up the system are operating normally. If the time required to communicate the pseudo event signal exceeds the allowable time, confirm that there is an abnormality in any system included in the disaster prevention information coordination system, or in the equipment or devices that make up the system. This makes it possible to predict abnormalities before they lead to failures or failures, and to take appropriate measures in advance. Additionally, the location of the abnormality can be identified from the communication route where the communication time exceeds the allowable time, making it possible to take appropriate measures.

(Effects of redundant system abnormality response)
In addition, the redundant first disaster prevention information infrastructure system and second disaster prevention information infrastructure system are such that one of them operates as the main system and the other operates as a subsystem, and the first disaster prevention information infrastructure system that is operating as the main system If an abnormality is determined in the information infrastructure system or the second disaster prevention information infrastructure system, the disaster prevention information infrastructure system running as the main system is stopped, and the disaster prevention information infrastructure system running as a subsystem is changed to the main system. Since the system is switched to operation, the main system and subsystems of the redundant disaster prevention information infrastructure system are switched based on the judgment result of the operation status of the disaster prevention information collaboration system based on the communication time required, and disaster prevention is carried out up to the linked system. It is possible to improve the certainty, stability, and reliability of operations that link information.

(Effects of user terminal and test terminal)
In addition, the user terminal displays event information included in the signal based on the event signal, and the test terminal is a terminal corresponding to the type of user terminal placed in the same communication environment as the user terminal, and the test terminal is a pseudo-equipment. Since the communication status of the first communication path and the second communication path from the computer to the self is displayed, the communication status of the first communication path and the second communication path from When using a user terminal, prepare a test terminal of a type corresponding to the type of the user terminal, and detect the communication status of the first communication route and the second communication route for each test terminal. By transmitting pseudo-event signals in a format similar to the coordination of disaster prevention information by transmitting event signals, it is possible to more accurately monitor abnormalities in the disaster prevention information coordination system.

(Communication environment between actual equipment and simulated equipment)
In addition, the actual equipment 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, and the pseudo equipment is installed at the installation location of the actual equipment and is not used by the actual equipment. Since communication is connected to the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system via a wireless communication device, the communication environment between the actual equipment and the simulated equipment is approximated as much as possible, and disaster prevention by transmitting event signals is possible. By transmitting pseudo-event signals in a form similar to information coordination, abnormalities in the operating status of the disaster prevention information coordination system can be more accurately monitored.

(Effect of simulated equipment)
In addition, the actual equipment is disaster prevention equipment equipped with a fire detector and a receiver, and the pseudo equipment is a pseudo receiver that is compatible with the receiver, or a pseudo receiver function that is realized by running a simulation program on a computer. Therefore, there is no need to cause the receiver of the disaster prevention equipment to transmit a pseudo event signal in order to monitor the operating state of the disaster prevention information coordination system, and to interrupt the disaster prevention monitoring and disaster prevention information coordination operation. In addition, in order to monitor abnormalities in the operating status of the disaster prevention information coordination system, the pseudo equipment only needs to be able to send pseudo event signals, and there is no need to monitor events such as fires and failures like actual equipment, so the minimum required It is possible to have a limited configuration, and costs can be kept down.

EMBODIMENT OF THE INVENTION Below, embodiment of the disaster prevention information cooperation system based on this invention is described in detail based on drawing. Note that the present invention is not limited to the following embodiments.

[Basic concept of embodiment]
First, the basic concept of the embodiment will be explained. The embodiment generally relates to a disaster prevention information coordination system.

A disaster prevention information coordination system is an event signal that contains event information indicating a predetermined event that occurred in actual equipment that performs disaster prevention monitoring, such as a fire or failure that occurred in a building with fire alarm equipment installed. For example, the event signal is sent to a disaster prevention information infrastructure system that can be communicated via a public general-purpose communication network including the Internet, and the event signal is sent from the disaster prevention information infrastructure system to a partner system with which disaster prevention information is linked. It is about linking information.

Further, the disaster prevention information infrastructure system includes a redundant first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system, and the event signal transmitted from the actual equipment is transmitted to at least the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system. Data is sent from one of the base systems to the linked system, and one operates as the main system and the other operates as a subsystem. The cooperation system also includes a cooperation destination information management system that receives event signals and transmits signals based on the event signals to user terminals.

Here, the "disaster prevention information infrastructure system" is a place for collecting and managing disaster prevention information based on event signals sent from actual equipment, and is connected for communication via public line general-purpose communication networks such as the Internet. This is a concept that includes possible computer systems, such as disaster prevention information platforms using cloud servers, equipment, devices, etc. for constructing such systems. Furthermore, "disaster prevention information" is a concept that includes information regarding various types of damage that cause damage to people's lives and society, such as fires, crimes, earthquakes, and floods.

In addition, the "disaster prevention information infrastructure system that operates as the main system" is a system that primarily operates when coordinating disaster prevention information, and how it operates as the main system is arbitrary, but for example, it can be used to receive event signals from actual equipment. The event information received and included in the event signal is accumulated, and the event signal containing the accumulated event information is transmitted to the cooperation partner system.

Furthermore, a "disaster prevention information infrastructure system that operates as a subsystem" is a system that backs up disaster prevention information so that it does not interfere with the coordination of disaster prevention information in the event that there is an abnormality in the system that primarily operates when collaborating with disaster prevention information. , how the subsystem operates is arbitrary, but for example, it receives event signals from actual equipment and stores the event information included in the event signals, but the event signals indicating the stored event information are sent to the cooperation destination. It does not send data to the information management system, but remains active in case an abnormality occurs in the main system, and if there is an abnormality in the disaster prevention information infrastructure system that is operating as the main system, it is switched to (promoted to) the main system. By operating as the main system, it transmits event signals to partner systems without interruption and maintains collaboration of disaster prevention information. Note that "active standby" means that the subsystem is on standby in an active state, and is a concept that includes "hot standby."

Regarding such a disaster prevention information collaboration system, the embodiments are capable of penetrating the operational status of the disaster prevention information collaboration system up to the user terminal of the collaboration destination information management system via the redundant disaster prevention information infrastructure system. In order to enable constant monitoring and improve the reliability, stability, and reliability of the disaster prevention information collaboration system, we will equip the collaboration partner system with a test terminal that is connected to the collaboration partner information management system, and provide simulated equipment. The same format as the event signal is sent from the equipment to each of the first communication route leading to the test terminal via the first disaster prevention information infrastructure system and the second communication route leading to the test terminal via the second disaster prevention information infrastructure system. The communication state of the first communication path and the second communication path is detected by transmitting a pseudo event signal.

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. In other words, the pseudo equipment is installed so that the communication environment for monitoring the operating state of the disaster prevention information collaboration system using the pseudo equipment approximates the communication environment for collaboration of disaster prevention information from the actual equipment to the collaboration destination information management system.

Furthermore, since it is desirable that the communication environment of the pseudo equipment be as close as possible to the communication environment of the actual equipment, the actual equipment may be connected to the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system by a wireless communication device, such as a wireless LAN communication device. If the communication connection is made using communication connection is made.

In addition, the configuration of "pseudo equipment" can be arbitrary as long as it transmits pseudo event signals, but for example, if the actual equipment is disaster prevention equipment equipped with a sensor and a receiver, the pseudo equipment will be able to receive A computer program that realizes the function of a pseudo receiver when executed on a computer device or a computer device.

Furthermore, a "pseudo-event signal" is an event signal that includes pseudo-event information indicating an event that is assumed to have occurred in a pseudo-nonexistent manner in order to monitor the operating status of the disaster prevention information coordination system, and the signal format is as follows: This is the same as an event signal that includes event information indicating an event that has occurred in actual equipment, and the pseudo event information included in the pseudo event signal corresponds to the event information of the event signal. Further, as event information included in the event signal, for example, event content information indicating the event content and a unique event ID (event identification information) for making each signal identifiable are included in the event signal, and pseudo event signals are also included. Similarly, event content information indicating that it is a pseudo event and a unique event ID (event identification information) are included.

Therefore, the pseudo event signal sent from the pseudo equipment to monitor the operating state of the disaster prevention information collaboration system can be processed in the same way as the event signal sent from the actual equipment, and the 2. It can be processed in the same way as event signals from actual equipment without changing the communication protocols of the disaster prevention information infrastructure system and the linked information management system.

Furthermore, as "detection of the communication state of the first communication path and the second communication path", the required communication time of the pseudo event signal by the first communication path and the communication time of the pseudo event signal by the second communication path is detected. be. In this case, regarding the detection of the required communication time, for example, the average value of the required communication time of the first communication path and the average value of the required communication time of the second communication path over a predetermined number of times are detected.

Here, the method for detecting the required communication time is arbitrary, but for example, the pseudo-equipment transmits pseudo-event signals that include event information that allows each pseudo-event signal to be identified (for example, includes a unique event ID). At the same time, sending time information that corresponds the sending time when the pseudo event signal was sent and the event information included in the sent pseudo event signal is sent to the test terminal, and the test terminal The event information included in the event signal is detected, and based on the transmission time corresponding to the event information detected from the transmission time information received from the pseudo equipment and the detected reception time, the communication time required for the pseudo event signal via the first communication path is determined. The time required for communication of the pseudo event signal via the second communication path is detected.

Furthermore, the transmission time information transmitted by the pseudo equipment is transmitted through a communication path that does not go through the cooperation destination information management system. Furthermore, the "communication path different from the first communication path and the second communication path" includes, for example, a known email communication path for transmitting sending time information as text information in the form of an email.

Furthermore, the disaster prevention information cooperation system determines the operating state of the disaster prevention information cooperation system based on the detected communication required time. Although the operational status of the disaster prevention information collaboration system can be determined arbitrarily, for example, if the communication time required for both the first communication route and the second communication route satisfy a predetermined permissible time condition, the disaster prevention information collaboration system is determined to be normal. If it is determined that the communication time required for the first communication route does not satisfy the permissible time condition and the communication time required for the second communication route satisfies the permissible time condition, it is determined that the first disaster prevention information infrastructure system is abnormal. However, if the communication time required for the first communication path satisfies the permissible time condition and the communication time required for the second communication path does not satisfy the permissible time condition, it is determined that there is an abnormality in the second disaster prevention information infrastructure system, and the second If both the communication time required for the first communication route and the second communication route do not satisfy the allowable time conditions, it is determined that there is an abnormality in the disaster prevention information coordination system.

Here, "determination of an abnormality" does not necessarily confirm the abnormality of the target system, but is a concept that includes determinations such as "there is a high possibility of an abnormality" and "there is a sign of an abnormality occurring."

In addition, if an abnormality is determined in the first disaster prevention information infrastructure system operating as the main system or 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 By shutting down the system and switching (promoting) the disaster prevention information infrastructure system, which is currently running as a subsystem, to the main system and running it, the linkage of disaster prevention information will not be disrupted.

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

Hereinafter, specific embodiments will be described. In the specific embodiment shown below, the "actual equipment" is "fire alarm equipment composed of a fire detector and a receiver", and the "first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system" are It is a "system constructed by duplicating the disaster prevention information infrastructure that functions as a disaster prevention information platform using a cloud server that can be connected for communication via a public general-purpose communication network such as the Internet", and the "cooperation partner system" is "the third system". The operation status of the disaster prevention information collaboration system is determined based on the detected communication time between the collaboration destination information management system that is communicatively connected to the first disaster prevention information infrastructure system and the second disaster prevention information infrastructure system, the user terminal, and the test terminal. A case will be described in which the system is equipped with a monitoring destination terminal that makes a judgment.

The fire alarm equipment 10 also communicates with the redundant first disaster prevention information infrastructure system 12 (12-1) and second disaster prevention information infrastructure system 12 (12-2) via the public line general-purpose communication network 18. Connected. One of the first disaster prevention information infrastructure system 12 (12-1) and the second disaster prevention information infrastructure system 12 (12-2) operates (operates) as a main system, and the other operates (operates) as a subsystem. Here, the description will be made 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 as an initial setting.

For example, equipment for constructing one system , equipment, etc. are installed in the Tokyo area, and equipment, equipment, etc. for constructing the other system are installed in the Osaka area. In addition, if it is possible to ensure that the collaboration of disaster prevention information is not interrupted, how should the first disaster prevention information infrastructure system 12 (12-1) and the second disaster prevention information infrastructure system 12 (12-2) be constructed? is optional.

The first disaster prevention information infrastructure system 12 (12-1) operating as the main system is communicatively connected to the cooperative information management system 14 via the public line general-purpose communication network 18. The second disaster prevention information infrastructure system 12 (12-2), which is operating as a subsystem, is in a standby state (active standby) in case of an abnormality in the first disaster prevention information infrastructure system 12 (12-1), which is operating as a main system. state), and is not communicatively connected to the cooperation destination information management system 14 via the public line general-purpose communication network 18.

A alive signal is sent periodically, and if an alive signal is received from the other party, it is determined that the other party is normal, and if an alive signal is not received from the other party a predetermined number of times in a row, it is determined that the other party is abnormal. If the subsystem determines that there is an abnormality in the main system, the subsystem is promoted to the main system and performs a degenerate operation to maintain its function as a disaster prevention information infrastructure system.

In addition, the fire alarm equipment 10 provided in the disaster prevention information collaboration system, the first disaster prevention information infrastructure system 12 (12-1), the second disaster prevention information infrastructure system 12 (12-2), the collaboration destination information management system 14, the user The terminal 16, the pseudo fire alarm equipment 100, the test terminal 110, and the monitored terminal 112 are time-synchronized through communication with a known time server or the like in order to match their time information with each other.

[b. Fire alarm equipment]
Next, the fire alarm equipment 10 will be explained. As shown in FIG. 1, the fire alarm equipment 10 includes a receiver 22, a fire detector 24, and a communication section 26. The fire alarm equipment 10 is a monitoring target, for example, a building or office of a business entity such as a company that owns the first disaster prevention information infrastructure system 12 (12-1) and the second disaster prevention information infrastructure system 12 (12-2). The fire detector 24 is installed in a monitoring area to be monitored, detects a fire occurring in the monitoring area, and transmits a fire signal to the receiver 22. Here, the "monitoring area" is the area where fire is monitored by fire alarm equipment, and if the monitoring target is a facility, it may include rooms, hallways, stairs, elevator halls, etc. within the facility, or parking lots outside the building. This is a concept that includes any area such as.

The receiver 22 receives a fire signal from the fire detector 24, detects the occurrence of a fire alarm or a failure, and notifies the failure alarm by, for example, sound and display, and also sends event content information indicating an event such as a fire or failure. and an event ID for uniquely identifying the event content information, and outputs an event signal including the event content information and the event ID to the communication unit 26. In addition, in the following description, the event signal transmitted from the fire alarm equipment 10 (receiver 22) may be referred to as a "cooperation source event signal."

Here, the event content information is information including event content and event occurrence location. The event content indicates the type of event that occurred, and includes fire, fire recovery, failure, and the like. The event occurrence location is, for example, the installation location of the fire detector 24 that detected the fire, and in order to easily identify the occurrence location on the linked user terminal 16, for example, "1st floor room 01", "1 District names such as "Floor Elevator Hall" are used. In addition, when fire alarm equipment is installed corresponding to multiple monitoring targets, the location where each fire alarm equipment is installed may be included in the event occurrence location, and information on the installation location of the fire detector 24 is not included. , information on the installation location of each fire alarm equipment may be used as the event occurrence location.

The communication unit 26 transmits the cooperation source event signal output from the receiver 22 to the first disaster prevention information infrastructure system 12 (12-1) and the second disaster prevention information infrastructure system 12 (12) via the public line general-purpose communication network 18. -2) is sent to two locations. Although the configuration and functions of the communication unit 26 are arbitrary, for example, a wireless LAN communication device such as a Wi-Fi (registered trademark) communication device with a router function is provided, and multicasting is used to transmit event signals to two locations at the same time. Alternatively, a well-known communication method known as a broadcast communication method is performed.

[c. Duplicated disaster prevention information infrastructure system]
Next, a redundant disaster prevention information infrastructure system will be explained. As shown in FIG. 1, the first disaster prevention information infrastructure system 12 (12-1) includes a control section 28 (28-1), a communication section 30 (30-1), a storage section 32 (32-1), and an operation display. A section 34 (34-1) is provided.

Specifically, the first disaster prevention information infrastructure system 12 (12-1) is a computer device equipped with a CPU, memory, a computer circuit equipped with various input/output ports, an external storage device such as a hard disk, a keyboard, a display, etc. For example, a disaster prevention information platform built on a cloud server that functions as a disaster prevention information platform that manages disaster prevention information as a cloud server. It is.

In addition, when the control unit 28 (28-1) receives a cooperation source event signal transmitted from the fire alarm equipment 10 via the communication unit 30 (30-1), the control unit 28 (28-1) controls the Control is performed to store content information and event ID in association with time information in the storage unit 32 (32-1) and accumulate it as event history information.

In addition, 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 the coordination source event signal from the fire alarm equipment 10 and stores it in the storage unit. 32 (32-1) generates an event signal including event content information and an event ID from the event history information accumulated in 32 (32-1), and controls the communication unit 30 (30-1) to transmit it to the cooperation destination information management system 14.

The second disaster prevention information infrastructure system 12 (12-2) also includes 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). 2) and is basically the same as the first disaster prevention information infrastructure system 12 (12-1), so the explanation thereof will be omitted.

The 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, receives the coordination source event signal from the fire alarm equipment 10. Control is not performed to generate an event signal including event content information and an event ID from the event history information accumulated in the storage unit 32 (32-1) and transmit it to the cooperation destination information management system 14.

In addition, the control units 28 (28-1) and 28 (28-2) cause each other to transmit alive/dead signals at predetermined intervals, for example, and when they receive the alive/dead signal from the other party, they determine that the other party is normal. If the alive/dead signal is not obtained a predetermined number of times in succession, it is determined that the other party is abnormal, and predetermined degeneration control is performed. Degeneration control is control in which a subsystem is promoted to a main system and operates as the main system.

In the following description, the 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 "cooperation destination event signals."

[d. Collaboration destination information management system]
Next, the collaboration destination information management system will be explained. As shown in FIG. 1, the collaboration destination information management system 14 includes a control section 36, a communication section 38, a storage section 40, and an operation display section 42. Specifically, it is a function that manages disaster prevention information that is constructed and linked using a computer device that is equipped with a CPU, memory, computer circuits equipped with various input/output ports, external storage devices such as hard disks, keyboards, displays, etc. For example, as a server, it is equipped with the function of operating and managing information regarding overall business operations of a company, and as part of its functions, a function of managing linked disaster prevention information is included.

A user terminal 16 is communicatively connected to the cooperation destination 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, a tablet terminal, a mobile terminal such as a smartphone, a personal computer, and the like.

If the server that processes the linked information management system 14, the user terminal 16, and the test terminal 110 are located in the same building, the dedicated communication network 20 is a LAN (Local Area Network) located within the building. It is preferable to consist of:

However, considering the case where the cooperation destination information management system 14 is not located in the same building as the user terminal 16 and the test terminal 110, such as when the cooperation destination information management system 14 provides services to multiple buildings, etc. , a public line general-purpose communication network may be used for at least a portion of the dedicated communication network 20.

[e. Collaborative operation of disaster prevention information]
Next, the disaster prevention information collaboration operation of the disaster prevention information collaboration system will be explained. In this description, reference will be made to FIG. 2, which shows a communication path in cooperation of disaster prevention information, and FIG. 3, which is a time chart showing the cooperation operation of disaster prevention information of the disaster prevention information cooperation system.

(e1. Communication route)
First, a communication path for collaboration of disaster prevention information will be explained. As shown in FIG. 2, on the side of the first disaster prevention information infrastructure system 12 (12-1) operating as the main system, from the fire alarm equipment 10 to the first disaster prevention information infrastructure system 12 (12-1) and the cooperation destination A communication path leading to the user terminal 16 via the information management system 14 is formed, and an event signal including event content information and its event ID that occurred in the fire alarm equipment 10 is transmitted to the user terminal 16 via the communication path. The event information is received and displayed on the user terminal 16.

On the other hand, regarding the second disaster prevention information infrastructure system 12 (12-2) operating as a subsystem, the communication path from the fire alarm equipment 10 to the second disaster prevention information infrastructure system 12 (12-2) is The same event signal as the event signal generated and transmitted to the first disaster prevention information infrastructure system 12 (12-1) via the communication path is transmitted to the second disaster prevention information infrastructure system 12 (12-2), 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 16 terminal via the cooperation destination information management system 14.

(e2. Cooperative operation of duplicated disaster prevention information)
Next, the cooperative operation of duplicated disaster prevention information will be explained. As shown in FIG. 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 S1). S2), both are operating. The operation in this case is based on 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). This is a controlled operation.

An event occurs (step S3), and the fire alarm equipment 1 transmits a coordination source 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 ).

Here, the link source event signal includes event content information and an event ID, so for example, if a fire occurs in the elevator hall on the first floor of a facility that is to be monitored as an event, "00:00:1 It includes event content information such as "A fire broke out in the elevator hall on the second floor" and, for example, "ID001" as an event ID for uniquely identifying the event content information.

Then, the first disaster prevention information infrastructure system 12 (12-1) that received the cooperation source event signal acquires the event content information and event ID included in the received cooperation source event signal, and uses the acquired event content information and event ID. and time information indicating the time of reception are correlated and stored and accumulated in the storage unit 32 (32-1) as event history information. Next, the first disaster prevention information infrastructure system 12 (12-1) generates a cooperation destination event signal including event content information and event ID from the accumulated event history information, transmits it to the cooperation destination information management system 14, and uses it. The user terminal 16 receives and displays the event information (steps S5, S7, S8).

On the other hand, the second disaster prevention information infrastructure system 12 (12-2) that received the cooperation source event signal acquires the event content information and event ID included in the received cooperation source event signal, and uses the acquired event content information and event ID. and time information indicating the received time are correlated with each other and stored and accumulated in the storage unit 32 (32-2) as event history information, but a cooperation destination event signal is generated and the cooperation destination information management server 14 The operation of transmitting the information to the destination is not performed (step S6).

Here, the monitoring operation 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) will be explained.

The first disaster prevention information infrastructure system 12 (12-1) and the second disaster prevention information infrastructure system 12 (12-2) mutually send life and death signals at predetermined intervals to determine whether the other party's operation is normal or abnormal. For example, by repeating the transmission at a one-minute cycle and continuing to receive the alive/dead signal, it is determined that the other party's system is operating normally. On the other hand, if the alive/dead signal is not received a predetermined number of times in succession, it is determined that the other party's operation is abnormal.

If an abnormality occurs in the first disaster prevention information infrastructure system 12 (12-1) operating as the main system (step S9), the second disaster prevention information infrastructure system 12 (12-2) operating as a subsystem Since it no longer receives the alive/dead signal from the first disaster prevention information infrastructure system 12 (12-1), it determines that there is an abnormality in the main system (step S10) and performs degeneration control.

Specifically, as the degradation control, the second disaster prevention information infrastructure system 12 (12-2) requests approval from the first disaster prevention information infrastructure system 12 (12-1) to operate as the main system. If there is no response from the main system within a predetermined time, or if there is a response indicating approval, the system is promoted to the main system and starts operating as the main system (step S11). ).

In this case, from the time an abnormality occurs in the first disaster prevention information infrastructure system 12 (12-1) until the second disaster prevention information infrastructure system 12 (12-2) starts operating as the main system, Since there is a possibility that the cooperation destination event signal is not being sent from the operating first disaster prevention information infrastructure system 12 (12-1) to the cooperation destination information management system 14, the second disaster prevention information infrastructure system 12 (12-1) 2) stores in the storage unit 32 (32-1) the event content information and event ID included in the cooperation source event signal received from the time when the alive/dead signal is no longer received until the time when the operation as the main system starts. A cooperation destination event signal including the specified event content information and event ID is generated and transmitted to the cooperation destination information management system 14, and the event information is received and displayed on the user terminal 16.

After the second disaster prevention information infrastructure system 12 (12-2) is promoted to the main system, an event occurs (step S13) and a cooperation source event signal is transmitted from the fire alarm equipment 10 (step S14). The disaster prevention information infrastructure system 12 (12-2) acquires the event content information and event ID included in the received collaboration source event signal, and uses the acquired event content information and event ID and time information indicating the time of reception. In association with each other, the event history information is stored and accumulated in the storage unit 32 (32-2), and a cooperation destination event signal including event content information and event ID is generated and transmitted to the cooperation destination information management system 14. , the event information is received and displayed on the user terminal 16 (steps S15, S16, S17).

On the other hand, for the first disaster prevention information infrastructure system 12 (12-1) in which an abnormality has occurred, the cooperative operation is stopped and an abnormality repair operation is performed to repair the abnormality that has occurred (step S12). Note that if recovery cannot be achieved by self-imposed abnormality repair operations, necessary repairs and the like will be performed by a person to recover.

When the first disaster prevention information infrastructure system 12 (12-1) is restored by an abnormal repair operation or repair (step S18), the second disaster prevention information infrastructure system 12 (12-2) restarts from the time when it stopped receiving the alive/dead signal. Event history information corresponding to the cooperation source event signal transmitted from the fire alarm equipment 10 before receiving the alive/dead signal is 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) stores the event history that may not be stored in the first disaster prevention information infrastructure system 12 (12-1). Storage synchronization (mirroring) that identifies information, generates an event signal containing the identified event content information and event ID, and sends it to the first disaster prevention information infrastructure system 12 (12-1) to match event history information on both sides. (Steps S19 and S20).

After synchronizing the event history information, the first disaster prevention information infrastructure system 12 (12-1) sets the subsystem to be demoted and starts cooperative operation (step S21).

In other words, after that, the first disaster prevention information infrastructure system 12 (12-1) will operate as a subsystem, and the second disaster prevention information infrastructure system 12 (12-2) will operate as the main system, and an event will occur. When the cooperation source event signal is transmitted from the receiver 22 of the fire alarm equipment 10, the event is stored in the storage unit 32 (32-2) based on the cooperation source event signal received by the second disaster prevention information infrastructure system 12 (12-2). In addition to accumulating history information, a cooperation destination event signal including event content information and event ID is generated and transmitted to the cooperation destination information management system 14, and the event information is received and displayed on the user terminal 16, and the first disaster prevention information infrastructure The system 12 (12-1) accumulates event history information in the storage unit 32 (32-1) based on the received collaboration source event signal, but does not transmit it to the collaboration destination information management server 14 (step S22~ S27).

[f. [Monitoring of system operating status]
Next, a monitoring operation for monitoring the operating state of the disaster prevention information coordination system will be explained. In order to monitor the operating state of the disaster prevention information coordination system, as shown in FIG. The system is provided with a test terminal 110 and a monitored terminal 112 corresponding to the user terminal 16.

(f1. Simulated fire alarm equipment)
First, the pseudo fire alarm equipment will be explained. The pseudo fire alarm equipment 100 is provided corresponding to the fire alarm equipment 10 as an actual equipment, and includes a pseudo receiver 102 and a transmitter 104.

The pseudo receiver 102 has a function of sequentially outputting a first pseudo event signal and a second pseudo event signal to the communication unit 104 at a predetermined system monitoring timing, for example, every minute, in order to monitor the operating state 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 equipment 10, which includes event content information and an event ID for uniquely identifying the event content information, and includes event content information and an event ID for uniquely identifying the event content information. The event ID includes information indicating that the event is a "pseudo-event" and a first event ID for uniquely identifying the pseudo-event as the event ID. The second pseudo event signal is also similar to the first pseudo event signal, but is different in that it includes the second event ID as the event ID.

Furthermore, the pseudo receiver 102 detects and holds the first transmission time when transmitting the first pseudo event signal, and detects and holds the second transmission time when transmitting the second pseudo event signal. Further, at a predetermined timing after transmitting the first pseudo event signal and the second pseudo event signal, the pseudo receiver 102 sends information associating the first event ID and the first transmission time, and the second transmission time and the second pseudo event signal. 2 Generates transmission time information including information associated with the event ID, and transmits the transmission time information to the first disaster prevention information infrastructure system 12 (12-1), the second disaster prevention information infrastructure system 12 (12-2), and the cooperation destination information. Control is performed to transmit data to the test terminal 110 via a communication path that does not go through the management system 14. To transmit 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 the transmission time information to the test terminal 110 via the email communication path.

Further, the fire detector 24 is not connected to the pseudo receiver 102, and the pseudo receiver 102 does not have a function to monitor or notify an event such as a fire, but is programmed with a function to send a pseudo event signal assuming that a pseudo event has occurred. It consists of a computer circuit realized by the execution of . Further, the pseudo receiver 102 can also be called a program that realizes the function by executing it by a computer.

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. The signal is sent to the second disaster prevention information infrastructure system 12 (12-2). Although the configuration and functions of the communication unit 104 are arbitrary, it is important to ensure a communication environment as close as possible to the communication unit 26 provided in the fire alarm equipment 10 as an actual equipment, for the entire system using pseudo event signals. In order to improve the accuracy of monitoring the communication status, a wireless LAN communication device such as the same communication device as the communication unit 26, such as a Wi-Fi (registered trademark) communication device equipped with a router function, is installed to monitor events at a specific location. It performs a well-known communication known as unicast for transmitting signals. Note that the communication section 26 and the communication section 104 may be configured as one communication section.

(f2. First communication route and second communication route)
Next, the first communication path and the second communication path used for monitoring the operating state of the system will be explained. In this description, reference is made to FIG. 4, which shows communication paths for monitoring the operating status of the system. Note that FIG. 4(A) shows the first communication path, and FIG. 4(B) shows the second communication path.

As shown in FIG. 4(A), the first communication path transmits the first pseudo event signal transmitted from the pseudo fire alarm equipment 100 to the first disaster prevention information infrastructure system 12 (12-1) and the cooperation destination information management system 14. This is a communication path for transmitting data to the test terminal 110 via the test terminal 110. Further, as shown in FIG. 4(B), the second communication path transmits the second pseudo event signal transmitted from the pseudo fire alarm equipment 100 to the second disaster prevention information infrastructure system 12 (12-2) and the cooperation destination information management. This is a communication path for transmitting data to the test terminal 110 via the system 14.

Here, if the system operating as the main system is the first disaster prevention information infrastructure system 12 (12-1), and the system operating as a subsystem is the second disaster prevention information infrastructure system 12 (12-2). , the first disaster prevention information infrastructure system 12 (12-1) accumulates event content information and event ID as event history information based on the cooperation source event signal received from the fire alarm equipment 10, and also stores event content information and event ID. A cooperation destination event signal including an ID is generated and transmitted to the cooperation destination information management system 14, and the event information is received and displayed on the user terminal 16, and the first pseudo event signal is transmitted from the pseudo fire alarm equipment 100. In this case, since event signals are received, event history information is accumulated, and event signals are transmitted in the same way, the operation is the same as that of the main system, and even when a pseudo event signal is received, the system operates as is.

Therefore, when the first disaster prevention information infrastructure system 12 (12-1) receives the first pseudo event signal, the first disaster prevention information infrastructure system 12 (12-1) records the event content information indicating the "pseudo event" and the first event ID based on the first pseudo event signal. In addition to accumulating the information, a first pseudo event signal including the event content information and the first event ID is generated and transmitted to the test terminal 110 via the collaboration destination information management system 14.

On the other hand, the second disaster prevention information infrastructure system 12 (12-2) accumulates event content information and event ID as event history information based on the cooperation source event signal received from the fire alarm equipment 10, but It does not perform the operation of generating a signal and transmitting it to the cooperation destination information management system 14, and cannot transmit the second pseudo event signal to the cooperation destination information management system 14 side by operating as a subsystem.

Therefore, when the second disaster prevention information infrastructure system 12 (12-2) that operates as a subsystem receives the second pseudo event signal, it stores the event content information and the second pseudo event ID as event history information. At this time, the event content information included in the second pseudo-event signal is identified as a "pseudo-event" and the function as a subsystem is temporarily canceled. The operation is changed so that a second pseudo event signal including event content information indicating a "pseudo event" and a second pseudo event ID is generated and transmitted to the test terminal 110 via the cooperation destination information management system 14.

Further, when receiving the first pseudo-event signal or the second pseudo-event signal, the cooperation destination disaster prevention management system 14 sends the same first pseudo-event signal or Control is performed to transmit the second pseudo event signal. In addition, when the collaborative disaster prevention management system 14 receives an email with transmission time information attached as text information via the email communication path 48, it transmits the received transmission time information to the test terminal 110 registered as a destination in advance. control.

(f3. test terminal)
Next, the test terminal 110 provided corresponding to the user terminal 16 communicatively connected to the cooperation destination information management system 14 will be described. In this description, reference is made to FIG. 5, which shows communication information including the required communication time detected by the test terminal 110 in a list format.

The test terminal 110 checks the communication status of the first pseudo event signal received via the first communication path 44 and the second pseudo event signal received via the second communication path 46 shown in FIG. The communication state is detected as the communication state, for example, the first communication time required for the first pseudo event signal and the second communication time required for the second pseudo event signal.

In order to detect the required communication time, the test terminal 110 uses the first reception time when the first pseudo event signal is received via the first communication path 44 in FIG. 4(A) as the received first pseudo event signal. and the first event ID included in the received first pseudo event signal, and also detect the first sending time corresponding to the first event ID included in the received first pseudo event signal from the sending time information received via the email communication path 48. From the detected first reception time and first transmission time,
(1st reception time) - (1st transmission time)
The first communication time required for the first communication path 44 is detected as follows.

Further, the test terminal 110 determines the second reception time when the second pseudo event signal is received via the second communication path 46 in FIG. ID and the second transmission time corresponding to the second event ID included in the received second pseudo event signal is detected from the transmission time information received via the email communication path 48. From the 2nd reception time and the 2nd transmission time,
(Second reception time) - (Second transmission time)
The second communication time required for the second communication path 46 is detected as follows. In the embodiment, the average required communication time is detected as the average value of the required communication times for a predetermined number of times.

FIG. 5 is an example of communication information 50 including the required communication time detected by the test terminal 110, and the communication information 50 includes the first transmission time and the first reception time detected corresponding to the first event ID, and the first communication required time detected based on these and the average first communication required time Tave1.

The same applies to the second communication path, and the communication information 50 includes the second transmission time and second reception time detected corresponding to the second event ID, and the second communication required time detected based on these. and its average second communication time Tave2.

(f4. Judgment of system operating status based on communication time)
Next, determination of the operating state of the system based on the required communication time will be explained. In this description, reference will be made to FIG. 6, which shows determination information 52 of the operating state of the system determined based on the required communication time.

In the embodiment, the communication information 50 detected by the test terminal 110 shown in FIG. I try to judge.

As for the operating state of the disaster prevention information coordination system, the degree of abnormality increases as the communication time required increases, so the monitored terminal 112 compares each of the first communication time required and the second communication time required with predetermined allowable time conditions. to determine whether the operating status of the disaster prevention information coordination system is normal or abnormal. Here, the predetermined permissible time condition is arbitrary, but for example, if the required communication time is less than or equal to the predetermined permissible time, it is accepted as satisfying the permissible time condition.

Specifically, as shown in FIG. 6, the monitored terminal 112 determines whether the first communication time does not satisfy the predetermined allowable time condition and the second communication time does not satisfy the predetermined allowable time condition. It is determined that there is an abnormality in the first disaster prevention information infrastructure system 12 (12-1).

In addition, if the first communication required time satisfies the predetermined allowable time condition and the second communication path does not satisfy the predetermined communication time required permissible time condition, the monitored terminal 112 monitors the second disaster prevention information infrastructure system. 12 (12-2) is judged to be abnormal.

In addition, if both the first communication time required for the first communication route and the second communication time required for the second communication route do not satisfy the allowable time condition, the monitored terminal 112 monitors the first disaster prevention information infrastructure system 12 ( 12-1) and the second disaster prevention information infrastructure system 12 (12-2), or when the linked information management system 14 is abnormal, there are multiple abnormality patterns. is determined to be an abnormality in the disaster prevention information coordination system without specifically identifying it. Note that all locations where there is a possibility of an abnormality may be selected as candidates.

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 is prepared as the test terminal 110, and each test terminal 110 has a first communication time and a second communication time. is detected, and the operating state of the disaster prevention information coordination system is determined based on the first communication required time and the second required communication time detected by each test terminal 110.

In addition, if an abnormality is determined in one of the disaster prevention information infrastructure systems operating as the main system based on the judgment of the operating state of the disaster prevention information collaboration system by the monitored terminal 112, the disaster prevention information infrastructure in which the abnormality has been determined is determined. The system stops operating as the main system, and the other disaster prevention information infrastructure system, which is operating as a subsystem, is promoted to the main system and starts operating.

[g. Monitoring operation of system operating status]
The operation of monitoring the operational status of the disaster prevention information coordination system will be explained. In this description, reference will be made to FIG. 7, which is a time chart showing the monitoring operation of the operating state of the disaster prevention information cooperation system. The following description assumes that the first disaster prevention information infrastructure system 12 (12-1) operates as a main system, and the second disaster prevention information infrastructure system 12 (12-2) operates as a subsystem.

As shown in FIG. 7, at a predetermined system monitoring timing during normal operation of the disaster prevention information coordination system, the pseudo fire alarm equipment 100 first sends a first pseudo 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 pseudo event signal and stores the event content information and the first event ID included in the first pseudo event signal as event history information. , generates a first pseudo event signal including the same event content information and first event ID, and transmits it to the test terminal 110 via the cooperation destination information management system 14, and the test terminal 110 receives and displays the pseudo event information. , the first display time at which the first pseudo event signal was received is detected (steps S101 to S105).

Moreover, when the pseudo fire alarm equipment 100 transmits the first pseudo event signal, it detects the first transmission time when the first pseudo event signal was transmitted, and also detects the first event ID of the transmitted first pseudo event signal and the first The transmission time is associated (steps S106, S107).

Subsequently, the pseudo fire alarm equipment 100 transmits the second pseudo event signal to the second disaster prevention information infrastructure system 12 (12-2), and the second disaster prevention information infrastructure system 12 (12-2) transmits the second pseudo event signal. Upon receiving the signal, the event content information and second event ID included in the second pseudo event signal are stored as event history information, and the operation of the subsystem is temporarily canceled based on the identification of the event content information, and the same event A second pseudo-event signal including content information and a second event ID is generated and transmitted to the test terminal 110 via the cooperation destination information management system 14, and the test terminal 110 receives and displays the pseudo-event information. A second reception display time at which the pseudo event signal is received is detected (steps S108 to S112).

Moreover, when the pseudo fire alarm equipment 100 transmits the second pseudo event signal, it detects the second transmission time at which the second pseudo event signal was sent, and also detects the first event ID of the sent second pseudo event signal and the second The transmission time is associated (steps S113, S114).

Subsequently, the pseudo fire alarm equipment 100 generates text data of transmission time information including information associating the first event ID with the first transmission time and information associating the second event ID with the second transmission time. The test terminal 110 receives the email from the pseudo receiver 102 and detects the first communication time required for the first communication route and the second communication time required for the second communication route. Then, the communication information 50, which is the detection result, is transmitted to the monitoring destination terminal 112 to judge the operating state of the system (steps S115 to S119). Note that since the first communication time and the second communication time are detected as the average value of a predetermined number of communication times, steps S101 to S116 are performed multiple times.
That process is omitted.

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), for example, promote the subsystem to the main system. Processing such as starting an operation is performed (step S120, step S121).

[h. Modification of the present invention]
Finally, a modification of the disaster prevention information coordination system according to the present invention will be explained. The disaster prevention information coordination system of the present invention includes the following modifications in addition to the above-described embodiments.

(Coordination of multiple actual equipment)
In the above embodiment, disaster prevention information of one fire alarm equipment is linked to a user terminal of one linked information management system via a redundant first disaster prevention information infrastructure system and a second disaster prevention information infrastructure system. We are taking a disaster prevention information collaboration system as an example, but the fire alarm equipment of multiple different business entities can be connected via the redundant first disaster prevention information infrastructure system and second disaster prevention information infrastructure system. It may also be a disaster prevention information collaboration system that is linked to a user terminal of a collaboration destination information management system.

(Judgment of system operating status)
In the above embodiment, the operating state of the system is determined by detecting the communication time required for the first communication path and the second communication path using a pseudo event signal as the communication state, but the detection of the communication state is limited to this. For example, the operating state of the system may be determined by detecting the communication speed (bps) of the first communication path and the second communication path using a pseudo event signal. Specifically, since the amount of data (number of bits) of the pseudo event signal is uniquely determined, the operating state of the system can be determined by detecting the communication speed (bps) based on the detected communication time and amount of communication data. to decide. Furthermore, in addition to the required communication time and communication speed, the operating state of the system may be determined by detecting, for example, an error rate.

(Monitoring of system operating status)
In the above embodiment, the test terminal 110 detects the required communication time as the communication state, and the monitored terminal 112 determines the system operating state based on the detection result, thereby monitoring the operating state of the system. This does not prevent a device other than the test terminal 110 from detecting the communication state and a device other than the monitored terminal 112 from determining the operating state of the system. For example, the system operating state may be determined by the test terminal 110 without providing the monitoring destination terminal 112, and the cooperation destination information management system 14 may be configured to perform these processes all at once. The terminal 110 and the monitored terminal 112 may not be provided. Furthermore, the test terminal 110 may also be configured to serve as the monitored terminal 112.

Further, the present invention includes appropriate modifications without impairing its objects and advantages, and is not limited by the numerical values shown in the above embodiments.
