[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a remote monitoring system, a remote monitoring method, a remote monitoring program, and a computer-readable recording medium that records the remote monitoring system for monitoring the state of a monitoring area via a communication line.
[0002]
[Prior art]
  2. Description of the Related Art Conventionally, in the field of security services for the purpose of security / monitoring of a security area, a mechanical security system that combines warning area abnormality detection / notification by a monitoring sensor and the dispatch of security guards based on this has become widespread. Compared to a human security system that always places security guards in all security areas, this type of mechanical security system has the advantage that it requires a small number of security personnel and can realize a reasonable security service. Yes.
[0003]
[Problems to be solved by the invention]
  However, the following problems have become apparent in the machine security system with actual operation. In other words, it is a useless dispatch of guards based on the false detection / false alarm of the monitoring sensor and a high cost structure based on this.
[0004]
  Here, the main factor of the false detection / false report by the monitoring sensor will be described.
[0005]
  First, the factors of false detection / false alarm on the security service provider side are as follows. In the case of adopting the mechanical security method, it is necessary to always set the sensitivity of various monitoring sensors to be high in order to reliably detect an abnormality in the warning area. This sensitivity setting is performed, for example, by adjusting the threshold value of the monitoring sensor. Thus, as a result of setting the sensitivity of the monitoring sensor to be high, the rate at which the monitoring sensor performs false detection / false alarm due to background noise inevitably increases.
[0006]
  Also, in recent years, with the trend toward design of buildings, the location of the monitoring sensor is limited so as not to impair the beauty, and the monitoring sensor has to be installed at a position where there is a lot of background noise (for example, vibration due to heavy rain). There are many cases where you do not get.
[0007]
  Furthermore, since a large number of security monitoring sensors are installed and driven for a long period of time, it is not uncommon for some of the monitoring sensors to fail. Of course, a faulty monitoring sensor has a very high possibility of false detection / false alarm.
[0008]
  Second, the factors of false detection / false alarm on the security service user side are as follows. In the machine security system, it is common for a user of a security service to set / cancel a warning state. However, erroneous detection / misreporting of a monitoring sensor due to a user's erroneous setting (for example, forgetting to release) is constantly occurring. In some cases, the monitoring sensor detects a user's locking error as abnormal.
[0009]
  In order to reduce such false detections / false alarms, security service providers combine monitoring sensors with different operating principles, and only when multiple monitoring sensors detect an abnormality, the monitoring sensor reports the abnormality detection. Although various measures are being sought, the fundamental problem has not been solved.
[0010]
  The present invention has been made to solve the above-described problems of the conventional method, and its purpose is a remote that can avoid wasteful personnel dispatch and confirmation work based on false detection / false alarm of a monitoring sensor. It is an object to provide a monitoring system, a remote monitoring method, a remote monitoring program, and a computer-readable recording medium recording the same.
[0011]
[Means for Solving the Problems]
  The present inventionIn order to solve the above-described problem, the remote monitoring system of the present invention includes a management device having detection information receiving means and detection information providing means,A user terminal having a display means;Instruction information receiving meansAnd monitoring control meansMonitoring system comprising a monitoring device includingAnd the said detection information receiving means receives the said detection information transmitted via a 1st communication line from the monitoring sensor which detects the state of a monitoring area as detection information, The said detection information provision means The detection information is transmitted to the user terminal via the second communication line, the display means displays the detection information received from the management device to the user, and the instruction information reception means is transmitted from the user terminal. Confirmation information indicating that the user has instructed confirmation of the monitoring area is received, and the monitoring control means determines whether or not the confirmation instruction information has been acquired, and confirms according to the content of the confirmation instruction information. ProcessIt is characterized by that.
[0012]
  In the above configuration, as the monitoring area, an arbitrary place where the user desires state monitoring can be set in advance. For example, an arbitrary area such as an office, a general home, a store, or a parking lot can be monitored.
[0013]
  As a monitoring sensor, if it is a sensor that detects the state of the monitoring area and its change, the type and quantity can be freely set. As a representative example of a monitoring sensor,(1)Photoelectric sensor, beam sensor, ultrasonic sensor, infrared sensor to detect human body in the monitoring area,(2)Vibration sensor, microphone, acceleration sensor to detect glass breakage in the monitoring area,(3)A video camera that images the surveillance area,(4)A temperature sensor, smoke sensor, humidity sensor, etc. that detect a fire in the monitoring area can be mentioned.
[0014]
  The first communication line and the second communication line may be in any form as long as the detection information can be transmitted and received. Therefore, any communication line such as a telephone, the Internet, and a local area network can be employed regardless of wired or wireless.
[0015]
  According to said structure, the said detection information which the monitoring sensor detected is transmitted via a 1st communication line, and is received by the detection information receiving means of the said management apparatus. Thereafter, the detection information providing means of the management device transmits the detection information to the user terminal via the second communication line.
[0016]
  Here, as user terminals, public telephones using public communication networks (including those equipped with an L mode (registered trademark) function), FAX, personal computers with modem functions, mobile phones, PHS (Personal-Handyphone) -System) and PDA (Personal-Digital-Assistant) can be used.
[0017]
  Here, the detection information providing means may convert the format of the detection information into a data format and data size suitable for the user terminal, or may transmit the data to the user terminal after being simplified. For example, when the user terminal is a mobile phone or the like, the data size can be reduced, or secondary information obtained by processing the detection information can be added to the detection information.
[0018]
  The timing at which the detection information providing means transmits the detection information to the user terminal is not particularly limited, and may be transmitted every predetermined period or according to other conditions.
[0019]
  Based on the detection information transmitted to the user terminal, the user sufficiently determines whether or not the situation of the monitoring area needs to be actually confirmed, and then enters the monitoring area through the user terminal. Confirmation information such as instructing the dispatch of personnel is transmitted. The monitoring area confirmation instruction information is received by the instruction information receiving means of the monitoring apparatus, and appropriate measures are taken accordingly. In other words, the monitoring device and its manager do not directly based on the detection information of the monitoring sensor, but perform a response based on the instruction information from the user terminal.
[0020]
  As a result, it is possible to avoid unnecessary personnel dispatch and confirmation work based on erroneous detection / false alarms of the monitoring sensor as in the conventional machine security system, so that the cost of security services can be greatly reduced.
[0021]
  the aboveIn order to solve the above problems, the remote monitoring system ofthe aboveIn the above configuration, the detection information providing means transmits the detection information to the user terminal only when the detection information indicates an abnormality in the monitoring area.
[0022]
  In the above configuration, when the detection information indicates an abnormality in the monitoring area, for example, when a numerical value included in the detection information of a specific monitoring sensor exceeds a predetermined threshold, or when a plurality of monitoring sensors react simultaneously. This is the time when it is determined that something has changed in the monitoring area based on the content of the detection information.
[0023]
  According to the above configuration, when there is a change in the monitoring area, the detection information is transmitted to the user terminal with a necessary minimum frequency.
[0024]
  Thisthe aboveIn addition to the effects of the above, effective remote monitoring can be realized while minimizing the burden of confirmation on the user.
[0025]
  the aboveIn order to solve the above problems, the remote monitoring system ofthe aboveIn the above configuration, the detection information providing means transmits the detection information to the plurality of user terminals based on a preset priority order.
[0026]
  In the above configuration, the priority order set in advance refers to, for example, a communication order determined according to a user's request when there are a plurality of user terminals that are transmission targets of the detection information. That is, priorities such as the first, second,..., Nth are assigned to a plurality of user terminals, respectively. These priorities are recorded in a data table or the like provided in the detection information providing unit as appropriate.
[0027]
  Here, the plurality of user terminals are not limited to terminals managed by the same user or terminals provided in the same place, but are far away from, for example, a terminal managed by the user's family or a terminal that is frequently used by the user. It may be a terminal provided at a location. The same priority may be given to some of the plurality of user terminals. In this case, so-called broadcast communication is performed for user terminals having the same priority.
[0028]
  According to said structure, even if it is a case where transmission of the said detection information with respect to a 1st user terminal fails, transmission of the said detection information with respect to a 2nd user terminal is performed. Similarly, the detection information is sequentially transmitted to different user terminals based on the priority order.
[0029]
  Therefore, when the user terminal is a wireless communication device such as a mobile phone and is in a communication disabled state due to a radio wave state or an operating state, or when a reception response by a predetermined user terminal is not made due to user convenience. Even if it exists, detection information is transmitted with respect to another user terminal.
[0030]
  Thisthe aboveIn addition to the operational effects, detection information can be reliably provided to the user. In addition, it becomes possible to appropriately provide detection information in an emergency.
[0031]
  the aboveIn order to solve the above problems, the remote monitoring system ofthe aboveIn the configuration, the detection information providing means repeats transmission of the detection information until connection with the user terminal is established.
[0032]
  According to the above configuration, when the user terminal is a wireless communication device such as a mobile phone and is in a communication disabled state due to a radio wave state or an operating state, a reception response by a predetermined user terminal is received due to user convenience. Even if the connection with one or more user terminals fails, such as when it is not possible, the detection information providing means is the user terminal.
For example, transmission of detection information is repeated at a predetermined time interval until a connection is established.
[0033]
  Thisthe aboveIn addition to the effects of
In addition to prompting, detection information can be provided more reliably.
[0034]
  the aboveIn order to solve the above problems, the remote monitoring system ofthe aboveIn the above configuration, the detection information providing means transmits the detection information to the user terminal only in a predetermined time zone.
[0035]
  In the above configuration, the predetermined time zone is a specific time zone that can be set according to the convenience of the user. For example, a time zone other than the user's bedtime or midnight can be set as the time zone. The set time zone is stored in the detection information providing means and its peripheral devices.
[0036]
  According to said structure, the said detection information is provided only in the time slot | zone which a user can respond | correspond, and a user will transmit the confirmation instruction information of a monitoring area according to this.
[0037]
  Thisthe aboveIn addition to the above-described effects, it is possible to eliminate a situation in which the detection information is transmitted in a time zone in which the user cannot respond and bothers the user.
[0038]
  the aboveIn order to solve the above problems, the remote monitoring system ofthe aboveIn the configuration, the management apparatus includes an information storage unit that stores the reception information of the detection information reception unit.
[0039]
  In the above configuration, the information storage means may be any configuration such as a semiconductor memory such as a RAM (Random Access Memory) or a ROM (Read Only Memory), an information recording device using a magnetic disk drive, an optical disk drive, or the like as a recording medium. Can be adopted.
[0040]
  According to the above configuration, the detection information received by the detection information receiving unit is sequentially stored in the information storage unit. The accumulation period may be unlimited or a predetermined period after accumulation. The information storage means preferably stores not only the detection information but also additional information such as the reception date and time and information of the monitoring sensor that is the transmission source.
[0041]
  Thisthe aboveIn addition to the effects of the past, it is possible not only to use and provide past detection information at any time, but also to comprehensively analyze processing information according to the purpose from the detection information group by centrally analyzing the detection information accumulated as a database. Can be obtained.
[0042]
  the aboveIn order to solve the above problems, the remote monitoring system ofthe aboveIn the above configuration, the detection information providing means transmits control information for controlling a reaction mode of the user terminal to the user terminal based on a history of detection information in the past.
[0043]
  In the above configuration, the history of detection information in the past refers to information such as past abnormality occurrence date / time, abnormality occurrence interval, abnormality occurrence frequency, and abnormality occurrence cause accumulated as a database. For example, the number of occurrences of abnormality within a predetermined period in the past, the reciprocal of the elapsed time from the previous reception of detection information indicating a monitoring area abnormality, and the like can be calculated as the abnormality occurrence frequency. Examples of past causes of abnormalities include failure of an alarm sensor, incorrect user setting, occurrence of a serious accident, and the like.
[0044]
  The control information for controlling the reaction mode of the user terminal is to control the operation mode when the user terminal receives the detection information. For example, in the incoming mode of the user terminal that is a mobile phone,(1)Incoming call display on the display,(2)Ring tone, ringtone type / volume,(3)This refers to information that controls the contents of vibration when receiving a call.
[0045]
  According to said structure, the detection information provision means can control the reaction form of a user terminal according to the log | history of detection information. For example, the detection information from a monitoring sensor that has reported a serious accident in the past or a monitoring sensor with a low misreporting history is classified into the most important level information, and the response form of the user terminal that is a mobile phone (maximum volume The user can be notified through a ring tone, simultaneous vibration, and a noticeable incoming call display.

[0049]
  According to said structure, according to the request | requirement of the user through the said user terminal, transmission of the detection information from the said detection information provision means to a user terminal is performed. For example, the user can request detection information at an unspecified time or request a large amount of detection information from a database.

[0112]
  [2. Monitoring area]
  Next, the monitoring area where the field device 1 is provided will be described.
[0113]
  Here, a predetermined area inside the office building is considered as the monitoring area. As described above, the field device 1 of the present embodiment includes a video camera (monitoring sensor 4a) that images the monitoring area, a photoelectric sensor (monitoring sensor 4b) that detects a human body in the monitoring area, and a window in the monitoring area. A vibration sensor (monitoring sensor 4c) attached to the glass is provided.
[0114]
  In particular, the video camera (monitoring sensor 4a) is the most effective sensor device as a detection sensor for grasping the state of the monitoring area. The installation location, the number of installations, and the imaging range (view angle) of the video camera in the monitoring area are appropriately set from the viewpoint of the area of the monitoring area and the economy. In recent years, CMOS (Complementary MOS) type video cameras can be obtained at a very low cost. In addition, if a socket system that is easy to attach and detach is used for installing the video camera (monitoring sensor 4a), the video camera (monitoring sensor 4a) can be reused between different monitoring areas.
[0115]
  The video camera (monitoring sensor 4a) not only captures the monitoring area, but also identifies changes in imaging data, that is, differential image data under the control of the on-site control unit 5 (see FIG. 1). It is possible to accurately grasp the state change of the monitoring area.
[0116]
  In the monitoring area, in addition to the monitoring sensors 4a to 4c, various monitoring sensors can be provided in any number according to the monitoring purpose, the monitoring object, and the economical viewpoint. Specifically, for the purpose of detecting fire, fire sensors that detect smoke and abnormal temperature rise, various built-in sensors incorporated in lighting, safes, air conditioners, etc., for the purpose of detecting abnormalities in equipment, Installation of an infrared sensor for the purpose of detecting suspicious persons outdoors can be considered. When selecting the monitoring sensor, it is preferable to employ a sensor that consumes relatively little power for convenience of maintenance.
[0117]
  Moreover, although the monitoring sensors 4a-4c and the site control part 5 may be connected by wire, it is also preferable to connect by various wireless means. This eliminates the need for complicated wiring even when the number of monitoring sensors 4a to 4c is large, and makes it easy to attach and manage the monitoring sensors.
[0118]
  Furthermore, in consideration of the case where additional monitoring sensors of the same kind are added, a unique ID (IDentification) number is assigned to the monitoring sensors 4a to 4c, and by acquiring the ID number from the monitoring sensors 4a to 4c, The on-site control unit 5 can specify each of the monitoring sensors 4a to 4c.
[0119]
  In addition to the inside of the office building, an arbitrary area such as a general house, a factory, a warehouse, a parking lot, an automobile, a train, a ship, a store, a hospital, and various facilities can be set as the monitoring area. For example, if a parking lot is to be monitored, this remote monitoring system can be used as a vehicle theft monitoring system. If a single person living alone, a baby, a care recipient in a hospital room, etc. is to be monitored, this remote monitoring system can be used as a nursing care system. can do. When this remote monitoring system is used as a care system, a care receiver's family, a welfare service provider, and the like operate the user terminal 16.
[0120]
  [3-1. Example of operation of this remote monitoring system]
  Next, an operation example of the remote monitoring system will be described with reference to FIG. In the flowchart shown in the figure, the operation (remote monitoring method) of the remote monitoring system is composed of steps S1 to S9. In the present embodiment, these steps are mainly based on the remote control program stored in the storage unit 10 (see FIG. 1) and the center control unit 9 of the center device 2 and the monitoring control unit 14 of the monitoring device 3 (see FIG. 1). Details of the processing in each step will be described sequentially.
[0121]
  In the first step, the center control unit 9 checks whether or not the remote monitoring method of the present invention (referred to as “user calling method” for convenience) is selected by the user as a precondition (S1). If the user calling method is not selected, the process proceeds to the conventional monitoring process. If the user calling method is selected, the process proceeds to the next step.
[0122]
  In the next step, the center control unit 9 determines whether or not the content of the detection information transmitted from the field device 1 and received by the detection information receiving unit 8 reports an abnormality (S2).
[0123]
  For example, the center control unit 9 may detect a case where a numerical value included in detection information of a specific monitoring sensor among detection information transmitted at a predetermined time interval exceeds a threshold value, or when a plurality of monitoring sensors react simultaneously. It can be determined that the content of the detection information reports an abnormality. However, such a determination process can be omitted when the configuration in which the detection information is transmitted from the field device 1 only when there is some abnormality.
[0124]
  In this step, by determining whether or not the content of the detection information reports an abnormality, in the subsequent step, the detection information is only displayed when the detection information indicates an abnormality in the monitoring area. (See FIG. 1). Therefore, effective remote monitoring can be realized while minimizing the burden of confirmation on the user.
[0125]
  If the center control unit 9 determines that the detection information does not report an abnormality, the center control unit 9 returns to S2 and continues the standby state. On the other hand, if the center control unit 9 determines that the detection information reports an abnormality, the center control unit 9 proceeds to the next step. .
[0126]
  In the next step, the center control unit 9 determines whether or not the current time is a time zone predetermined by the user or the like (S3). Here, as a predetermined time zone, a user's bedtime, a time zone excluding midnight, etc. can be set according to the convenience of the user. The center control unit 9 avoids such a time zone and makes contact with the user, thereby providing the detection information only in a time zone that can be handled by the user and reducing the burden on the user.
[0127]
  If the current time does not belong to the time zone, the center control unit 9 shifts to the conventional monitoring process, whereas if the current time belongs to the time zone, the center control unit 9 proceeds to the next step.
[0128]
  In the next step, the center control unit 9 controls the detection information providing unit 11 (see FIG. 1) to make a call process to the user terminal 16 that is a contact address stored / set in the storage unit 10 in advance. (S4). As described above, in this embodiment, the user terminal 16 is a mobile phone, and the detection information providing unit 11 is connected to the user via a mobile phone communication network (not shown) and the Internet network 15 (see FIG. 1). The terminal 16 is called. Of course, examples of the user terminal 16 and the calling means are not limited to the above examples.
[0129]
  In S4, when the connection with the predetermined user terminal 16 cannot be established due to the absence of the user or the like, the center control unit 9 and the detection information providing unit 11 set the priority ( 1st to Nth), a plurality of user terminals 16 are sequentially contacted (called) (S5).
[0130]
  Here, the plurality of user terminals 16 is not limited to a terminal managed by the same user or a terminal provided in the same place, and is far away from, for example, a terminal managed by the user's family or a terminal frequently used by the user. It may be a terminal provided at a different position. The same priority may be given to some of the plurality of user terminals 16. In this case, so-called broadcast communication is performed for the user terminals 16 having the same priority.
[0131]
  According to the process of this step, when the user terminal 16 is a wireless communication device such as a mobile phone and is in a communication disabled state due to a radio wave state or an operating state, or according to a user's convenience, a predetermined user terminal 16 Even when the reception response cannot be made, the detection information is reliably transmitted to the other user terminals 16.
[0132]
  In the steps S4 to S5, it is preferable that the center control unit 9 and the detection information providing unit 11 repeat the call communication (detection information transmission) until the connection with each user terminal 16 is established. Thereby, even if it is a case where a connection with a single or several user terminal fails, it becomes possible to provide the said detection information more reliably.
[0133]
  In the next step, the center control unit 9 and the detection information providing unit 11 provide the detection information to the user terminal 16 (S6). Although the detection information to be provided is arbitrary, it is preferable that captured image information of the monitoring area such as detection information by the monitoring sensor 4a (see FIG. 1) is included.
[0134]
  In this case, the format and data size of the captured image information included as detection information are arbitrary. In general, detailed photographed image information is preferable, but communication capacity between the detection information providing unit 11 and the user terminal 16 is also taken into consideration when determining the format and data size.
[0135]
  If the captured image information is included in the detection information provided to the user terminal 16, the user can visually confirm the state of the monitoring area through the display unit 30 (see FIG. 2) provided in the user terminal 16. . As a result, it is possible to make the user's monitoring area state grasp and various judgments more appropriate.
[0136]
  In this step, it is preferable that the center control unit 9 and the detection information providing unit 11 also transmit control information for controlling the reaction mode of the user terminal 16 based on the history of detection information in the past. [3-2. This will be described later in the “Reaction pattern control of user terminal” column.
[0137]
  In the next step, the monitoring control unit 14 of the monitoring device 3 determines whether or not there is a monitoring area confirmation instruction (confirmation instruction information) from the user terminal 16 through the instruction information receiving unit 13 (see FIG. 1) (S7). ). As an example of the confirmation instruction, there is an instruction for urging a guard to the monitoring area. At this time, it is preferable that the monitoring control unit 14 performs a billing process according to the number and contents of the confirmation instruction information.
[0138]
  In this step, when the center control unit 9 and the monitoring control unit 14 determine that there is no monitoring area confirmation instruction from the user terminal 16, the center control unit 9 and the monitoring control unit 14 return to S <b> 2 and continue the standby state. If it is determined that there is a confirmation instruction, the process proceeds to the next step.
[0139]
  In the next step, the monitoring control unit 14 performs a confirmation process according to the content of the monitoring area confirmation instruction (S8). This process may be performed directly by the monitoring control unit 14 based on the control function, or a specific operation (monitoring) may be performed on a monitoring person / guardian or the like through a display device, a speaker, or the like appropriately provided in the monitoring apparatus 3. It may be performed indirectly by prompting the area to express / confirm or reset the monitoring sensors 4a to 4c).
[0140]
  The result of the confirmation process may be recorded as report data including analysis of the cause of the abnormality (for example, deterioration of the monitoring sensors 4a to 4c, abnormal adjustment, user operation error, forgetting to lock, etc.), on-site photo information, etc. preferable.
[0141]
  In the last step, the monitoring control unit 14 sends the result of the confirmation processing in S8 and information obtained by the confirmation (including the report data) to the user terminal 16 via the instruction information receiving unit 13 and the communication line 12. Transmit (S9). Thereby, the user can grasp the confirmation result of the monitoring area and the cause of the abnormality.
[0142]
  Usually, continuous remote monitoring is performed by repeating the steps S1 to S9.
[0143]
  Note that the information obtained in each step, in particular the information received by the detection information receiving unit 8 (see FIG. 1) of the center device, is preferably stored in the storage unit 10 or the like. The storage unit 10 preferably stores not only the detection information but also additional information such as the reception date and time and information of the monitoring sensors 4a to 4c that are transmission sources. The accumulation period may be unlimited or a predetermined period after accumulation.
[0144]
  As a result, users and third parties can not only use and provide past detection information at any time, but also collect and analyze detection information accumulated as a database to comprehensively match the detection information group according to the purpose. Can be obtained.
[0145]
  In the remote monitoring system (remote monitoring method), the center control unit 9 and the detection information providing unit 11 are configured to transmit the detection information to the user terminal 16 in response to a request from the user terminal 16. Is also preferable. As a result, the user can request detection information at an unspecified time or request more detection information (such as past database or other monitoring area information). The user can solve the anxiety of whether or not the monitoring area has been properly closed by the above request.
[0146]
  [3-2. User terminal reaction control]
  Here, the details of the reaction mode control of the user terminal 16 referred to in S6 will be described with reference to the drawings.
[0147]
  As described above, in step S6, the center control unit 9 and the detection information providing unit 11 (see FIG. 1) change the reaction form of the user terminal 16 (see FIG. 1) based on the history of detection information in the past. It is preferable to transmit control information to be controlled.
[0148]
  Here, the history of detection information in the past refers to past abnormality occurrence date and time, abnormality occurrence interval, abnormality occurrence frequency, abnormality occurrence cause, etc. accumulated as a database in the storage unit 10 (see FIG. 1) of the center device 2 or the like. This information.
[0149]
  4A and 4B are explanatory diagrams showing examples of the database.
[0150]
  In FIG. 5A, the detection information received by the detection information receiving unit 8 is recorded as event data. In each event data, the date and time of occurrence and the cause of cause classification (numerals) are recorded. Examples of the cause of cause classification include various things such as weather, user setting error, monitoring sensor failure, and the like.
[0151]
  In FIG. 5B, as the statistical event data of the detection information received by the detection information receiving unit 8, the number of events or an abnormality occurrence interval for each predetermined period is recorded.
[0152]
  Accordingly, the center control unit 9 and the detection information providing unit 11 (see FIG. 1) are configured so that the elapsed time from the previous event in the database shown in FIG. 4A, the abnormality occurrence interval, and the period shown in FIG. By referring to the data for each, it is possible to calculate the past abnormality occurrence frequency and to know the cause.
[0153]
  In this remote monitoring system (remote monitoring method), the reaction mode of the user terminal 16 is controlled based on the history of such detection information.
[0154]
  Here, the control information for controlling the reaction mode of the user terminal 16 controls the operation mode when the user terminal 16 receives the detection information. For example, in the incoming mode of the user terminal 16 which is a mobile phone,(1)Incoming call display on the display,(2)Ring tone, ringtone type / volume,(3)This refers to information that controls the contents of vibration when receiving a call.
[0155]
  The center control unit 9 and the detection information providing unit 11 can control the reaction mode of the user terminal 16 according to the history of detection information in the past by transmitting these control information. For example, the detection information from a monitoring sensor that has reported a serious accident in the past or a monitoring sensor with a low misreporting history is classified into the most important level information, and the fact that the user terminal 16 has a response form (a ringing tone with a maximum volume or The user can be notified through simultaneous vibration, noticeable incoming call display, etc.).
[0156]
  On the contrary, the detection information from the monitoring sensors 4a to 4c that are clearly out of order and the monitoring sensors 4a to 4c that frequently report false alarms are classified into light-level information, and the fact that the user terminal 16 This can be reflected in the response form (such as a response only for incoming call display).
[0157]
  As a result, the remote monitoring system (remote monitoring method) can call the user's attention according to the importance level of the detection information and the estimated level of the risk level. This can improve the burden on the user.
[0158]
  FIG. 5 is a flowchart illustrating an example of a procedure in which the center control unit 9 selects an important level of detection information in accordance with a history of detection information in the past. In the flowchart of FIG. 5, the level selection procedure includes steps S11 to S16. In this embodiment, these steps are processed based on the remote monitoring program. Details of the processing in each step will be described sequentially.
[0159]
  In the first step, the center control unit 9 adds the contents of the new detection information to the database stored in the storage unit 10, and confirms the history of detection information in the past based on this database (S11).
[0160]
  In the next step, the center control unit 9 analyzes the detection information history (including the cause of the event occurrence) confirmed in S11, so that past detection information may be misreported (for example, due to a failure of the monitoring sensors 4a to 4c). ) Is included (S12).
[0161]
  If the center control unit 9 determines that the past detection information does not include false alarms, the center control unit 9 selects the most important level (alarm level 0), assuming that the monitoring area is extremely likely to be in an abnormal state. If it is determined that the past detection information includes misinformation, the process proceeds to the next step.
[0162]
  In the next step, the center controller 9 sequentially compares the previous occurrence intervals with k1, k2,..., Kn-1 (k1> k2> ...> kn-1), or / At the same time, the number of past false alarms is sequentially compared with m1, m2,..., Mn-1 (m1 <m2 <... <mn-1). Classify (S13 to S16).
[0163]
  In the flowchart of FIG. 5, alarm level 0 has the maximum relative alarm intensity, and alarm level n has the minimum relative alarm intensity. That is, the longer the abnormality occurrence interval from the previous time is, and / or at the same time, the lower the number of past false alarms, the higher the possibility that the detected information of this time is the true information, and the stronger alarm level is given.
[0164]
  Therefore, according to the present embodiment, depending on the alarm level, the longer the abnormality occurrence interval from the previous time, and / or at the same time, the lower the number of past false alarms, the higher the alerting power of the user terminal 16 to the user. The form will be selected.
[0165]

It may be a medium carrying a fixed program including a semiconductor memory such as a disk system, an IC card (including a memory card) / optical card, or a mask ROM, EPROM, EEPROM, flash ROM, etc. .
