Description

[Technical field]

[0001] The present disclosure relates to a management system, a water level sensor that outputs water level information to the system, a management method, and a management program. [Background technology]

[0002] Facilities such as homes, stores, and offices are equipped with abnormality detectors such as fire alarms. Fire alarms have the function of outputting an alarm sound when a fire is detected. The Fire Service Act requires that each dwelling unit be equipped with a residential fire alarm (residential fire alarm). Naturally, a residential fire alarm does not output an alarm sound to encourage residents to evacuate unless it detects a fire. However, a system has been proposed that uses this residential fire alarm to notify disaster prevention information transmitted from municipal disaster prevention radio equipment (see Patent Document 1).

[0003] The disaster prevention alarm linkage system disclosed in Patent Document 1 is configured to convert the protocol of an emergency information report signal sent from a municipal disaster prevention radio equipment by a relay adapter and send it to a residential alarm device, outputting disaster prevention information such as an emergency earthquake alert and a tsunami alert to each residence. Patent Document 1 also describes that when a periodically transmitted test linkage signal is received, a voice message of test disaster prevention information is not output, but an indicator light is activated to notify, and an audio message is output when the alarm stop switch is operated while the indicator light is activated.

[0004] [Patent Document 1] JP 2019-3401 A Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, it is said that heavy rain disasters have become more severe and frequent. For example, if heavy rain causes rivers to overflow and homes and other facilities to become flooded, it can lead to dangerous situations that put people at risk of death, so it is important to evacuate quickly at the appropriate time. To encourage residents to evacuate quickly, it is necessary to provide more reliable information about flooding in the surrounding area. However, this is not an easy task, and it is particularly difficult to provide information to elderly people.

[0006] The object of the present disclosure is to provide a management system that can more reliably inform users of information regarding flood damage in surrounding areas and enable rapid evacuation at the appropriate time. [Means for solving the problem]

[0007] The management system of the present disclosure is a management system that is communicatively connected to an anomaly detector installed in a facility, and is characterized in that it comprises an acquisition unit that acquires water level information regarding the water level in a specific area, and an output unit that generates an alarm based on the water level information and outputs information regarding the alarm to the anomaly detector, a registered communication terminal, and at least one of the devices installed in the registered facility.

[0008] The water level sensor according to the present disclosure is a water level sensor installed in the specific area, and is characterized in that it outputs the water level information to the management system.

[0009] The management method disclosed herein is a method for outputting information related to flood damage, and is characterized by including the steps of acquiring water level information related to the water level in a specific area, and generating an alert based on the water level information, and outputting information related to the alert to at least one of the abnormality detector, a registered communication terminal, and equipment installed in a registered facility.

[0010] Furthermore, a management program according to the present disclosure is a program for implementing the above method on a computer. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an example of an embodiment of the present disclosure will be described in detail with reference to the drawings. The embodiment described below is merely an example, and the present disclosure is not limited to the following embodiment. In addition, a form obtained by selectively combining multiple modified examples described below is included in the scope of the present disclosure.

[0014] The subject of the device and system of the present disclosure includes a computer. The computer executes a program to realize the functions of the subject of the device and system of the present disclosure. The computer includes a processor that operates according to the program as a main hardware configuration. The type of the processor does not matter as long as it can realize the above functions by executing the program. The processor is composed of one or more electronic circuits including an integrated circuit (IC) or a large scale integrated circuit (LSI). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. The program is stored in a non-transitory storage medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be stored in the storage medium in advance, or may be supplied to the storage medium via a wide area communication network including the Internet.

[0015] 1 and 2 are diagrams showing a regional disaster prevention system 1 including a management system (receiver 10 and management server 20) which is an example of an embodiment. The regional disaster prevention system 1 is a system for protecting residents, commuters, students, and other visitors (hereinafter referred to as "residents, etc.") in a specific area A from flood damage, and includes a management system communicably connected to an abnormality detector 30 installed in a facility such as a house 6, and a plurality of water level sensors 50 installed in the specific area A. The management system constituting the regional disaster prevention system 1 acquires water level information on the water level in the specific area A from the water level sensor 50, etc., generates an alarm based on the water level information, and outputs information related to the alarm to the anomaly detector 30, for example.

[0016] In this embodiment, the management system is composed of a receiver 10 installed in each residence 6, etc., and a management server 20 communicatively connected to the receiver 10. The management server 20 is communicatively connected to a plurality of water level sensors 50, and is configured to acquire water level information from each water level sensor 50 at the installation location of the sensor. The receiver 10 acquires the water level information via the management server 20, for example, generates an alarm based on the water level information, and outputs information about the alarm to an abnormality detector 30 installed in each residence 6.

[0017] As will be described in more detail later, the management server 20, for example, analyzes the water level information obtained from the water level sensor 50, determines the water level for the specific area A, for each section within that area, or for each location where a receiver 10 is installed, and transmits the water level information corresponding to each receiver 10. The receiver 10 or management server 20 may change the content of the warning depending on the water level, and may also change the output destination of the warning. The water level is an indicator of the risk of flooding, specifically the level of flooding in urban areas, etc. For example, when the water level sensor 50 installed in an urban area detects a certain water level, it means that the urban area is flooded, and the water level becomes high.

[0018] The scope of the specific area A to which the regional disaster prevention system 1 is applied is not particularly limited, but may be, for example, an administrative district such as a city, town, village, or ward, or may be an even smaller area. The specific area A may also be determined based on a hazard map for floods, landslides, and the like. The management server 20 does not need to be located in the specific area A, as long as it is capable of communicating with the receivers 10, water level sensors 50, and the like within the specific area A. The management server 20 may be shared by regional disaster prevention systems of multiple areas.

[0019] In the specific area A, there are public facilities such as a city hall 2, a school 3, a park 4, a river 5, and a house 6. Although not shown in FIG. 1, the specific area A may also include public facilities such as a library, a community center, a fire station, a police station, a station, a hospital, and other facilities, as well as commercial facilities such as shops and shopping malls, offices, factories, and hotels. Furthermore, the house 6 is not limited to a detached house, and may be an apartment building, a nursing home, or other collective housing. In addition, as described above, a plurality of water level sensors 50 are installed in the specific area A.

[0020] The regional disaster prevention system 1 is a system that uses the functions of the management system (receiver 10 and management server 20) to output the above-mentioned alarm from anomaly detectors 30 installed in houses 6 and the like in a specific area A, and more reliably informs users of information regarding flood damage in the surrounding area. The content of the alarm outputted is such as "Flooding has begun. Please begin evacuation" or "It is a dangerous situation. Please begin evacuation immediately" depending on the water level indicating the degree of risk of flood damage. The management system may further output information regarding the alarm to a communication terminal 40 registered in advance, or to equipment installed in related facilities 7 registered in advance.

[0021] The water level sensor 50 is a device that is installed in the specific area A and outputs water level information to the management system. The water level sensor 50 may be any device capable of measuring the water level at the installation location of the sensor, and the type of the sensor is not particularly limited. The multiple water level sensors 50 do not need to be the same type of sensor, and may be different sensors. Examples of the water level sensor 50 include electromagnetic wave or ultrasonic non-contact sensors, float type, guide rope type, pressure type, and other contact sensors. A camera may also be used as the water level sensor 50, and the water level may be obtained from an image captured by the camera.

[0022] The water level sensor 50 is installed in a public facility such as a city hall 2, a school 3, or a park 4, but the water level sensor 50 may be installed in a house 6, a non-residential facility 8 such as a store, an office, or a factory, or on a road. The water level sensor 50 does not need to be a dedicated device for the regional disaster prevention system 1, and may be configured such that, for example, the management server 20 acquires water level information from an existing sensor. In other words, an existing water level sensor may be used as the water level sensor 50 for the regional disaster prevention system 1. The multiple water level sensors 50 may include a sensor that measures the water level of the river 5.

[0023] It is preferable that the water level sensors 50 are installed evenly throughout the specific area A. Generally, schools 3, parks 4, etc. are placed at a certain distance apart within an administrative district, so the schools 3 and parks 4 are suitable locations for installing the water level sensors 50. The installation locations of the water level sensors 50 may also be determined based on hazard maps for floods, landslides, etc. In this case, it becomes easier to obtain useful information, and the water level sensors 50 can be installed efficiently.

[0024] Hereinafter, the management system (receiver 10, management server 20) and the anomaly detector 30 communicably connected to the receiver 10 will be described in detail with reference to FIGS. 2 and 3. FIG.

[0025] As described above, the management system constituting the regional disaster prevention system 1 includes the receiver 10 communicatively connected to the anomaly detector 30, and the management server 20 communicatively connected to the receiver 10 and the water level sensor 50. The receiver 10 is a device including a control unit 11 and a storage unit 12, and has a function of acquiring water level information of the specific area A, and outputting information related to an alarm to the anomaly detector 30 based on the water level information. The receiver 10 is installed in a residence 6, such as a detached house or an apartment building, for example, but may also be installed in a non-residential facility 8, such as a library, a community center, a hospital, a store, an office, or a hotel.

[0026] One example of the abnormality detector 30 is a fire alarm that detects smoke, heat, etc. and notifies the occurrence of a fire. A fire alarm installed in a house 6 or the like is generally called a residential alarm. The fire alarm may not only warn of a fire by voice or buzzer sound, but also transmit fire occurrence information to the receiver 10. The abnormality detector 30 may be a device that can detect abnormalities such as gas leaks and the intrusion of suspicious persons in addition to fires. The above-mentioned management system is a system that utilizes this abnormality detector 30 to more reliably notify information about flood damage in the surrounding area.

[0027] In this embodiment, the management server 20 acquires water level information from multiple water level sensors 50, processes the information, and transmits it to the receiver 10. As illustrated in FIG. 2, when the receiver 10 and the water level sensor 50 are installed in one home 6 or non-residential facility 8, the receiver 10 may acquire water level information directly from the water level sensor 50. In this case, it is preferable that the water level information of the water level sensor 50 is transmitted to the management server 20 via the receiver 10 and used for outputting an alarm together with water level information of other water level sensors 50 installed in the specific area A. Note that multiple anomaly detectors 30 may be installed in the non-residential facility 8, and the receiver 10 and the anomaly detector 30 may be communicably connected via a repeater 31 (similar to the case of the home 6).

[0028] The receiver 10 includes an acquisition unit 14 that acquires water level information, and an output unit 15 that outputs information related to an alarm to the anomaly detector 30 based on the water level information. The acquisition unit 14 and the output unit 15 may be configured as part of the control unit 11. The control unit 11 is configured, for example, by a microcomputer equipped with a processor, memory, an input / output interface, etc., and realizes the functions of the acquisition unit 14 and the output unit 15 by reading and executing a management program stored in the storage unit 12. The storage unit 12 may be a non-volatile memory of the microcomputer that configures the control unit 11, or may be configured as a device separate from the microcomputer.

[0029] The receiver 10 may be any device that is communicatively connected to the management server 20 and the anomaly detector 30 and has the functions of the acquisition unit 14 and the output unit 15, but in this embodiment, the receiver 10 further includes an alarm unit 13 that can issue an alarm. The receiver 10 may be a dedicated device for the regional disaster prevention system 1, but may also be shared with devices that constitute an energy management system, an intercom system, or the like installed in the residence 6. In addition, these systems generally include a gateway that relays communications between networks with different protocols, and this gateway may be used as the receiver 10.

[0030] In addition to the above-mentioned gateway, a specific example of the receiver 10 is a controller of an energy management system that manages power consumption in the house 6. That is, the functions of the acquisition unit 14 and the output unit 15 are added to the controller and used as the receiver 10. Alternatively, the functions of the acquisition unit 14 and the output unit 15 may be added to a parent unit of an intercom system and used as the receiver 10. By using existing equipment as the receiver 10, it becomes easier to introduce the system and the introduction costs can be reduced. The controller of the energy management system, the parent unit of the intercom system, etc. may have a gateway function.

[0031] The receiver 10 preferably includes at least one of a monitor and a speaker as the notification unit 13. A controller of an energy management system and a parent unit of an intercom system are generally equipped with a monitor and a speaker. The receiver 10 causes the anomaly detector 30 to output an alarm, but if the receiver 10 includes the notification unit 13, the receiver 10 can also output an alarm from the notification unit 13. The receiver 10 generates an alarm based on water level information, for example, and outputs the alarm to the anomaly detector 30 and also to the notification unit 13.

[0032] The acquisition unit 14 of the receiver 10 acquires water level information related to the water level in the specific area A. The acquisition unit 14 acquires water level information detected by the water level sensor 50 via the management server 20, but may also acquire water level information directly from some of the water level sensors 50. The management server 20, like the receiver 10, is equipped with an acquisition unit 21 and an output unit 22 in order to acquire water level information from the water level sensor 50 and output it to the receiver 10. The receiver 10 preferably acquires water level information analyzed and processed by the management server 20, and acquires, for example, information on the water level determined from the water level information by the management server 20. A number of water level levels are set according to the degree of risk of flood damage.

[0033] Specific examples of water level include the following four levels. (1) Level 1: The city is not flooded, but the water level of the river has exceeded a certain level, and countermeasures should be initiated. Level 1 is the flood risk detection threshold. (2) Level 2: The stage where flooding of urban areas begins and evacuation should begin. Level 2 is the flood occurrence detection threshold (evacuation start threshold). (3) Level 3: Flooding has progressed to the point where immediate evacuation is necessary. Level 3 is the emergency evacuation threshold. At Level 3, for example, flooding above the floor level exceeds 50 cm, and a house is deemed partially destroyed based on the "Certification of Damage to Residential Buildings Related to Disasters" established by the Cabinet Office. (4) Level 4: The stage where flooding occurs above the floor level and rescue is necessary. Level 4 is the threshold for requesting rescue. At Level 4, for example, flooding occurs above the floor level and exceeds 180 cm, and the house is recognized as having been completely destroyed based on the above Cabinet Office certification criteria.

[0034] The acquisition unit 21 of the management server 20 acquires water level information, for example, when the water level detected by the water level sensor 50 installed in the river 5 exceeds a predetermined value. Then, when the management server 20 acquires the water level information, it determines that the water level is 1. Alternatively, the water level sensor 50 may constantly measure the water level of the river 5, and the management server 20 may compare the water level information of the water level sensor 50 with the predetermined value. In either case, when the water level of the river 5 exceeds the predetermined value, the management server 20 determines that the water level is 1. When the water level reaches 1, the management server 20 transmits water level information to the receiver 10.

[0035] In this embodiment, the water level may be used to determine whether or not to output an alarm from the anomaly detector 30, etc. Specifically, the threshold level is set to 1, and when the water level is equal to or higher than the threshold level, information on the water level is transmitted from the management server 20 to the receiver 10, and an alarm is output from the anomaly detector 30. The predetermined value of the water level of the river 5 that is the criterion for determining the water level level 1 is, for example, the flood danger water level. In other words, an alarm is output from the anomaly detector 30, etc., on the condition that the water level of the river 5 flowing through the specific area A exceeds the flood danger water level. The management server 20 may determine the water level level to be 0 when the water level of the river 5 is equal to or lower than the predetermined value.

[0036] The management server 20 also acquires water level information from water level sensors 50 installed in urban areas, etc. of the specific area A, and determines a water level that is higher than level 1. This makes it possible to grasp the presence or absence of flooding in urban areas, etc. of the specific area A, and the extent of the flooding. It is preferable that the management server 20 determines the water level for each of a plurality of zones in the specific area A.

[0037] The management server 20 creates a map showing the extent of flooding (water level) in urban areas, etc., based on water level information acquired from multiple water level sensors 50 installed in urban areas, etc., and land height information obtained from hazard map information, etc. At this time, the water level information from multiple nearby water level sensors 50 is taken into consideration, and the extent of flooding is calculated while interpolating data. This makes it possible to determine the water level (extent of flooding) in the location where the receiver 10 is installed (each house 6, etc.) and the area where the houses 6, etc. are located.

[0038] The output unit 15 of the receiver 10 generates an alarm based on the water level information, and outputs information about the alarm to at least one of the anomaly detector 30, the registered communication terminal 40, and the equipment installed in the registered related facility 7. The output unit 15 generates an alarm based on the water level determined by the management server 20, for example. The output unit 15 preferably outputs information about the alarm to at least the anomaly detector 30, and may output information about the alarm to the registered communication terminal 40 or the equipment installed in the related facility 7 in addition to the anomaly detector 30. In this embodiment, the output of information to the communication terminal 40 and the related facility 7 is performed via the management server 20.

[0039] The output unit 15 may select at least one of the devices installed in the anomaly detector 30, the registered communication terminal 40, and the registered related facility 7 based on the water level information, and output information related to the alarm to the selected output destination. In other words, the output destination of the alarm is not fixed, but is changed according to the acquired water level information. By outputting an alarm to a pre-registered communication terminal 40, for example, even when the user is not at home 6, it is possible to quickly grasp the danger approaching the home 6, and to urge children, elderly people, etc. in the home 6 to evacuate. In addition, outputting information related to the alarm to the pre-registered related facility 7 is effective in evacuation and recovery after flood damage.

[0040] Examples of the communication terminal 40 include mobile terminal devices owned by the user, such as a smartphone, a mobile phone, a tablet terminal, and a notebook computer. The registered communication terminal 40 refers to a terminal in which identification information used for communication is stored in at least one of the receiver 10 and the management server 20. A terminal device in which application software (app) of the regional disaster prevention system 1 is installed can be used as the communication terminal 40 to which an alarm is output. The receiver 10 or the management server 20 stores, for example, an identifier (device token) of the communication terminal 40, but may also store a user ID, an email address, a phone number, etc.

[0041] The device installed in the related facility 7 means a device in which information used for communication (e.g., telephone number, email address, terminal device identification information, etc.) is stored in at least one of the receiver 10 and the management server 20. The related facility 7 is a facility to which information regarding flood damage in the house 6 or the like should be transmitted, and specific examples include facilities that request rescue such as local governments, fire departments, and police, and facilities related to infrastructure such as electric power companies and communication companies. In addition, if the user has subscribed to flood insurance, the related facility 7 may be an insurance company.

[0042] The output unit 15 changes the output destination of the alarm according to the water level determined from the water level information, for example, and outputs different alarm destinations for water levels 1 and 4. As a specific example, when the water level is low, such as levels 1 and 2, the output destination of the alarm is the abnormality detector 30 and the registered communication terminal 40, and when the water level is high, such as levels 3 and 4, the output destination of the alarm is the registered related facility 7. Note that the abnormality detector 30 may be set as the output destination of the alarm at all water level levels. Similarly, the communication terminal 40 may be set as the output destination of the alarm at all water level levels.

[0043] It is preferable that the output unit 15 increases the number of alarm output destinations when the water level rises. The output unit 15 may increase the number of output destinations stepwise as the water level rises from a lower water level to a higher water level, or may increase the number of output destinations when the water level reaches a predetermined level or higher. Since the risk of flooding increases as the water level rises, it is preferable to increase the number of alarm output destinations to respond more quickly and accurately. Specifically, at level 1, the alarm output destination is set to only the anomaly detector 30, at level 2, the output destination is set to the anomaly detector 30 and the communication terminal 40, and at levels 3 and 4, the output destination is set to the anomaly detector 30, the communication terminal 40, and the equipment of the related facility 7.

[0044] It is preferable that the output unit 15 changes the content of the warning according to the water level determined from the water level information. In this case, when the water level rises, it becomes easier to inform the user that the risk of flooding is increasing, and it is possible to encourage the user to evacuate quickly.

[0045] Specific examples of the contents of the warning include the following: (1) Level 1: A voice message such as "The water level of the XX River has reached the flood danger level. Please check the hazard map and begin preparing for evacuation" is output from the anomaly detector 30. A similar message is also transmitted to the communication terminal 40. (2) Level 2: A voice message such as "Flooding has started. Please begin evacuation" is output from the abnormality detector 30. A similar message is also transmitted to the communication terminal 40. (3) Level 3: A voice message such as "This is a dangerous situation. Please begin evacuation immediately" is output from the abnormality detector 30. A similar message is also transmitted to the communication terminal 40. In addition, registered related facilities 7, such as the local government, fire department, police, and insurance companies, are notified that flooding at water level 3 has occurred in the home 6. (4) Level 4: A voice message such as "Request a rescue" is output from the abnormality detector 30. A similar message is also transmitted to the communication terminal 40. In addition, registered related facilities 7, such as the local government, fire department, police, and insurance companies, are notified that flooding at water level 4 has occurred in the house 6.

[0046] An alarm may be generated based on the water level determined by the management server 20, and information about the generated alarm may be output to the receiver 10 or the like. In this case, the receiver 10 simply relays the information and outputs it to the anomaly detector 30. The output unit 22 of the management server 20 may select and change the output destination of the alarm according to the water level. The output unit 22 may change the content of the alarm according to the water level, select at least one of the devices installed in the anomaly detector 30, the registered communication terminal 40, and the registered related facility 7, and output information about the alarm to the selected output destination. That is, it is sufficient that each of the above functions is realized as the management system as a whole.

[0047] An example of a control process of the management system constituting the regional disaster prevention system 1 will be described below with reference to the flowchart of FIG.

[0048] One example of a control process (management method) of the management system is a method of outputting information related to flood damage, which includes the steps of acquiring water level information related to the water level in a specific area A, and generating an alarm based on the water level information and outputting information related to the alarm to at least one of the devices installed in the anomaly detector 30, the registered communication terminal 40, and the registered related facility 7. This method is realized, for example, by executing a management program stored in the receiver 10 and the management server 20. An example of a specific control procedure is as follows.

[0049] As shown in Fig. 4, the receiver 10 and management server 20 that constitute the management system jointly execute a control process. In step S1, the management server 20 acquires water level information from multiple water level sensors 50 installed in specific area A. In the example shown in Fig. 4, the water level of at least the river 5 that flows through specific area A is constantly measured, and the water level information of the river 5 is transmitted to the management server 20. In step S2, the management server 20 determines a water level that indicates the risk of flooding from the acquired water level information.

[0050] As described above, the management server 20 creates a map showing the degree of flooding based on water level information from multiple water level sensors 50 installed in urban areas and the like of the specific area A and information on the land height of each section of the specific area A. Then, for each location where a receiver 10 is installed, the management server 20 determines one of four water level levels, 1 to 4. If the water level of the river 5 is equal to or lower than a predetermined value, the management server 20 may determine the water level to be 0.

[0051] The management server 20 compares the water level with a threshold level, and if the water level is equal to or higher than the threshold level (Yes in step S3), transmits the water level as water level information to the receiver 10 (step S4). The threshold level is set to level 1, for example. That is, if the water level of the river 5 measured by the water level sensor 50 exceeds a predetermined value and the water level is determined to be 1, information on the water level 1 is transmitted to the receiver 10. On the other hand, if the water level is not determined to be 1 or higher, that is, if the water level of the river 5 is equal to or lower than the predetermined value, the process does not proceed to step S4 and ends (No in step S3).

[0052] When the receiver 10 acquires the water level information via the management server 20 (step S5), it generates an alarm based on the water level information (step S6). The receiver 10 changes the content of the alarm and the output destination of the alarm according to the water level (steps S6 and S7). When the water level becomes high, the content of the alarm encourages quick evacuation, and as described above, when the water level is 3, the alarm will be something like "It is a dangerous situation. Please start evacuating immediately." Also, when the water level becomes high, the output destination of the alarm is increased, and for example, when the water level is 3 or higher, in addition to the abnormality detector 30 and the communication terminal 40, the relevant facilities 7 such as the local government and the fire department are selected as the output destination of the alarm. The procedures of steps S6 and S7 may be executed by the functions of the management server 20.

[0053] In step S8, the receiver 10 outputs information related to the alarm to the anomaly detector 30. When outputting information to the communication terminal 40 and related facilities 7 registered in the management system, the alarm is output via the management server 20 (step S9). When the water level drops, it is preferable to output alarm cancellation information to the alarm output destination.

[0054] In step S10, the management server 20 may provide data showing the flooding state of the house 6 (for example, a map showing the water level in the house 6 and the extent of the flooding) to an electric power company, a communication company, a local government, an insurance company, etc. The data provided by the management server 20 is useful for restoring infrastructure after the occurrence of a flood and determining the scope of insurance coverage.

[0055] As described above, the regional disaster prevention system 1 equipped with the above-mentioned management system can more reliably inform users of information regarding flood damage in the surrounding area. As a result, prompt evacuation at an appropriate time becomes possible. By using anomaly detectors 30, such as fire alarms, installed in each residence 6 to output flood-related warnings, information can be conveyed quickly even to elderly people. In addition, since existing equipment can be used, the system can be easily introduced and introduction costs can be reduced.

[0056] The above embodiment may be modified as appropriate without impairing the purpose of the present disclosure. For example, in the above embodiment, an alarm to the communication terminal 40 and the related facility 7 registered in the management system is output from the management server 20, but it is also possible to output it directly from the receiver 10. It is also possible to add the function of the receiver 10 to the anomaly detector 30. [Explanation of symbols]
