  FIG. 3 is a sequence diagram illustrating an operation flow when the remote control system 1 according to the first embodiment is operating normally. In FIG. 3, only one device is shown for convenience of explanation, but the number of devices is not limited to one.

  First, the detection device 10 transmits a detection signal to the communication device 30 (step S101). The communication device 30 receives the detection signal transmitted from the detection device 10 (step S102). The communication device 30 transmits the received detection signal to the server 40 (step S103).

  The server 40 receives the detection signal transmitted by the communication device 30 (step S104). The server 40 records the received detection signal in the storage unit 403 (step S105). The server 40 executes control processing based on the received detection signal (step S106). The server 40 transmits the control signal generated by the control process to the communication device 30 (step S107).

  The communication device 30 receives the control signal transmitted from the server 40 (step S108). The communication device 30 transmits the received control signal to the controlled device 20 (step S109). The controlled device 20 receives a control signal from the communication device 30. The controlled device 20 operates according to the received control signal. By such an operation, the controlled device 20 is controlled according to the detection information acquired by the detection device 10. Such an operation is repeatedly executed each time the server 40 receives a detection signal, for example.

  Further, at a predetermined timing, the server 40 determines whether or not there is an abnormality in the remote device (step S110). No abnormality has occurred in the sequence diagram of FIG. Therefore, the process after step S110 is not performed. The predetermined timing may be, for example, a timing at which a detection signal is received, a timing at which a predetermined time has elapsed since the previous determination process, or another timing.

Next, the flow of operation when an abnormality occurs in the remote control system 1 will be described.
FIG. 4 is a sequence diagram illustrating an operation flow when an abnormality occurs in the remote control system 1 according to the first embodiment. In FIG. 4, only one device is shown for convenience of explanation, as in FIG. However, the number of devices is not limited to one. In FIG. 4, the same processes as those in FIG.

  At a predetermined timing, the server 40 determines whether there is an abnormality in the remote device (step S110). In the sequence diagram of FIG. 4, an abnormality has occurred. Therefore, the server 40 determines that an abnormality has occurred. In this case, the server 40 transmits a notification signal indicating that an abnormality has occurred to the terminal device 50 (step S201). The notification signal includes information related to the remote device that is determined to be abnormal (hereinafter referred to as “abnormal information”). The abnormality information includes, for example, information indicating identification information of a remote device determined to be abnormal, information indicating a position of a remote device determined to be abnormal, and determining that an abnormality has occurred. Information indicating the time of day is included.

  The terminal device 50 receives a notification signal from the server 40 (step S202). Based on the received notification signal, the terminal device 50 displays information on the remote device in which the abnormality is detected on the display unit 503 (step S203).

  Next, the flow of processing performed by the server 40 will be described in detail. Hereinafter, two specific examples of processing performed by the server 40 will be described.

(First example)
FIG. 5 is a diagram illustrating a flow of a first specific example of the process performed by the server 40. In the first specific example, the criterion is a length of time during which the detection signal is not continuously received. The determination unit 402 of the server 40 determines whether there is an abnormality for each communication device 30 based on the timing at which the detection signal is received. In the first specific example, the process illustrated in FIG. 5 is executed independently for each communication device 30.

  First, the control unit 404 receives a detection signal from the communication device 30 (for example, the communication device 30-1) (step S301: step S104 in FIG. 4). The control unit 404 acquires the current time (step S302). The control unit 404 records the received detection signal in the storage unit 403 in association with the identification information of the communication device 30 that is the transmission source and the current time (step S303: step S105 in FIG. 4).

  The control unit 404 executes control processing based on the detection signal received from the communication device 30 (step S304: step S106 in FIG. 4). The control unit 404 transmits the generated control signal to the communication device 30 that is the transmission source of the detection signal received in step S301 (step S305: step S107 in FIG. 4).

  After step S305, the determination unit 402 determines whether a new detection signal transmitted from the communication device 30 has been received (step S306). When the detection signal transmitted from the communication device 30 is received (step S306-YES), the process returns to step S302.

  When a new detection signal is not received (step S <b> 306 -NO), the determination unit 402 refers to the storage unit 403, and the detection signal continues based on the time when the detection signal was last received for each communication device 30. Time not received (hereinafter referred to as “unreceived time”) is acquired (step S307).

The determination unit 402 determines whether or not the unreceived time exceeds the reference time for each communication device 30 (step S308). Specific examples of the reference time are 0.1 second, 1 second, 10 seconds, 30 seconds, 1 minute, 10 minutes, 30 minutes, 1 hour, and 24 hours. The reference time may be set to a different length for each communication device 30. The reference time may be stored in advance in the storage unit 403 or may be set by the user.
When the non-reception time does not exceed the reference time for all the communication devices 30 (step S308-NO), the process returns to step S306.

  When the unreceived time exceeds the reference time (step S308—YES), the determination unit 402 has an abnormality in the remote device (the detection device 10, the controlled device 20, or the communication device 30) related to the communication device 30. It is determined that For example, when the unreceived time of the communication device 30-1 exceeds the reference time, the determination unit 402 determines that an abnormality has occurred with respect to the detection device 10-1, the controlled device 20-1, or the communication device 30-1. Specific examples of the abnormalities that occur include disconnection of communication between the communication device 30-1 and the server 40, failure of the detection device 10, failure of the controlled device 20, failure of the communication device 30, failure of the first network 60, There is a failure of the second network 70 or the like.

  If the determination unit 402 determines that there is an abnormality related to the communication device 30, the determination unit 402 stores the abnormality determination information of the communication device 30 in the storage unit 403 (step S309). The abnormality determination information includes information related to the communication device 30 determined to be abnormal and a determination time determined to be abnormal.

(Second specific example)
FIG. 6 is a diagram illustrating a flow of a second specific example of the process performed by the server 40. In the second specific example, the determination criterion is a criterion relating to the content of the detection signal. In the second specific example, the determination unit 402 of the server 40 determines whether there is an abnormality based on information included in the received detection signal.

  First, the control unit 404 receives a detection signal from the communication device 30 (for example, the communication device 30-1) (step S401: step S104 in FIG. 4). The control unit 404 acquires the current time. The control unit 404 records the received detection signal in the storage unit 403 in association with the identification information of the communication device 30 that is the transmission source and the current time (step S402: step S105 in FIG. 4).

  The control unit 404 executes control processing based on the detection signal received from the communication device 30 (step S403: step S106 in FIG. 4). The control unit 404 transmits the generated control signal to the communication device 30 that is the transmission source of the detection signal received in step S401 (step S404: step S107 in FIG. 4).

  Next, the determination unit 402 determines whether or not there is an abnormality in the detection signal received from the communication device 30 (step S405). The determination unit 402 determines whether there is an abnormality in the detection signal based on information included in the detection signal.

  For example, the determination unit 402 determines that the detection signal is abnormal when the difference between the data included in the detection signal and the reference value exceeds a preset threshold value. The reference value may be stored in advance in the storage unit 403, or may be an average value of data accumulated in the storage unit 403. The preset threshold value may be stored in the storage unit 403 in advance.

For example, the determination unit 402 may determine whether there is an abnormality in the detection signal based on a result of performing a predetermined calculation using data included in the detection signal. The calculation result may be, for example, a difference between data included in the detection signal and an average value of past data stored in the storage unit 403, or frequency analysis is performed on the data included in the detection signal. It may be a result.
The determination unit 402 stores the calculation result in the storage unit 403.

  If there is no abnormality in the detection signal (step S405—NO), the process returns to step S401. On the other hand, when the detection signal is abnormal (step S405—YES), the determination unit 402 is a remote device (the detection device 10, the controlled device 20 or the communication device 30) related to the communication device 30 that is the transmission source of the detection signal. It is determined that an abnormality has occurred.

  If the determination unit 402 determines that there is an abnormality related to the communication device 30, the determination unit 402 stores the abnormality determination information of the communication device 30 in the storage unit 403 (step S406). The abnormality determination information includes information related to the communication device 30 determined to be abnormal and a determination time determined to be abnormal.

FIG. 7 is a flowchart showing a process flow of the terminal device 50.
The control unit 505 receives a notification signal from the server 40 via the communication unit 501 (step S501). The control unit 505 acquires information related to the communication device 30 determined to be abnormal from the received notification signal (step S502). For example, the control unit 505 acquires information indicating a location where the communication device 30 that is determined to be abnormal is installed. The control unit 505 stores the acquired information in the storage unit 502 (step S503). The control unit 505 displays the acquired information on the display unit 503 (step S504).

[Modification]
A modification of the server 40 will be described. The determination unit 402 of the server 40 in the modification determines whether or not a disaster has occurred in the land where the remote device is installed. Hereinafter, a configuration and processing of a modified example of the server 40 will be described.

  The storage unit 403 further stores information related to the installation environment of the remote device. The information related to the installation environment of the remote device is, for example, information on a map including a place where the communication device 30 is installed, information on a disaster that is currently occurring, a probability of occurrence of a disaster in the vicinity of the place where the communication device 30 is installed, and the like. . The probability of occurrence of a disaster in the vicinity of the installation location of the communication device 30 is information obtained using information obtained by predicting a disaster in advance. For example, it may be represented as a hazard map.

(Third example)
FIG. 8 is a diagram illustrating a flow of a specific example (third specific example) of processing performed by the server 40 in the modification. In the third specific example, the determination criterion is the length of time during which the detection signal is not continuously received. In the third specific example, the determination unit 402 also determines the occurrence of a disaster. In the description of the third specific example, the same processes as those of the first specific example are denoted by the same reference numerals as those in FIG.

  After the process of step S309, the determination unit 402 determines that there is an abnormality within a predetermined time in addition to the communication device 30 determined to be abnormal in step S308 based on the abnormality determination information stored in the storage unit 403. It is determined whether there is a determined communication device 30 (steps S310 and S311). When it is determined that there is such a communication device 30 (step S310-YES and step S311-YES), the determination unit 402 determines that each determined communication device 30 has been damaged. In this case, the control unit 404 transmits a notification signal including information on each communication device 30 determined to be damaged to the terminal device 50 (step S312: step S202 in FIG. 4).

(Fourth specific example)
FIG. 9 is a diagram illustrating a flow of a specific example (fourth specific example) of processing performed by the server 40 in the modification. In the fourth specific example, the determination criterion is a criterion relating to the content of the detection signal. In the fourth specific example, the determination unit 402 also determines the occurrence of a disaster. In the description of the fourth specific example, the same processes as those of the second specific example are denoted by the same reference numerals as those in FIG.

  After the process of step S409, the determination unit 402 determines that there is an abnormality within a predetermined time in addition to the communication device 30 determined to be abnormal in step S405 based on the abnormality determination information stored in the storage unit 403. It is determined whether there is the determined communication device 30 (steps S407 and S408). When it is determined that there is such a communication device 30 (step S407-YES and step S408-YES), the determination unit 402 determines that each determined communication device 30 has been damaged. In this case, the control unit 404 transmits a notification signal including information on each communication device 30 determined to be damaged to the terminal device 50 (step S409: step S202 in FIG. 4).

  In the conventional remote control system, it is sometimes difficult to quickly grasp the damage situation around the remote device when a disaster occurs. For example, it may be difficult to understand the impact of a disaster in units of buildings where remote devices are installed from information (for example, disaster occurrence information in units of regions) announced by the government or the like when a disaster occurs. In addition, for example, when a remote device breaks down when a disaster occurs, it may be difficult to determine whether or not it is due to the influence of the disaster.

  With respect to such a problem, in the remote control system 1 of the modified example, the determination unit 402 determines whether or not a disaster has occurred at the installation location of the remote device. Therefore, it is possible to determine more accurately and more quickly whether or not a disaster has occurred at the installation location of the remote device.

In the remote control system 1, the communication device 30 may have a configuration corresponding to the determination unit 402. If the determination unit 402 determines that an abnormality has occurred in the communication with the server 40, the determination unit 402 may determine that a failure has occurred in the server 40 that has been communicating so far. In this case, the control unit 303 may start transmitting a detection signal to the server 40 different from the previous one.
The determination unit 402 may calculate the probability of damage for each disaster type for the remote device at the position where it is determined that a disaster has occurred. In this case, the determination unit 402 may store in advance a table in which disaster occurrence probabilities are associated with each combination of the area where each remote device is installed and the type of disaster that occurs. The determination unit 402 may calculate the probability based on this table.
The determination unit 402 may determine a communication device that may be damaged in the future based on position information of a position where it is determined that a disaster has occurred. In this case, the determination unit 402 may store in advance a table in which the area where each remote device is installed and the area that may be damaged in the future when a disaster occurs in that area. The determination unit 402 may determine the communication device based on this table.

  According to at least one embodiment described above, by having the determination unit 402 that determines the presence / absence of abnormality based on communication with the communication device 30 and transmits the determination result to the terminal device 50, Presence / absence can be determined more quickly.
