Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a communication fault detection method and a remote monitoring center. [Background technology]
[0002] It is possible to provide a remote monitoring service for equipment using the communication networks provided by telecommunications carriers. Some of the equipment being remotely monitored is critical equipment, such as freezers that cool drug storage rooms at pharmaceutical companies, which would cause significant damage if they stopped operating. For such critical equipment, if remote monitoring is not possible due to a communication network failure, it will be necessary to take measures such as stationing workers on-site. Therefore, it is necessary to identify the equipment experiencing a communication failure.
[0003] Patent Document 1 describes that information indicating the current status of communication carriers can be acquired by crawling SNS (Social Networking Service) or various news sites. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 723104 Summary of the Invention [Problem to be solved by the invention]
[0005] However, the information released by telecommunications carriers about communication failures is vague, and they do not provide information on which specific devices are experiencing communication failures. It is possible to detect the presence or absence of communication failures by periodically querying the communication status of all installed devices, but this increases communication costs.
[0006] Therefore, an object of the present disclosure is to provide a communication failure detection method and a remote monitoring center that can detect a device in which a communication failure occurs with a low communication frequency. [Means for solving the problem]
[0007] The communication failure detection method disclosed herein includes a first acquisition step in a learning stage of acquiring information representing the area of the communication failure; a first detection step in the learning stage of detecting whether or not a communication failure has occurred in one or more monitoring panels within the area of the communication failure; a step in the learning stage of registering a group consisting of one or more monitoring panels in which a communication failure has occurred; a step in the learning stage of determining one monitoring panel within the group as a representative; a second acquisition step in the detection stage of acquiring information representing the area of the communication failure; a second detection step in the detection stage of detecting whether or not a communication failure has occurred in a representative monitoring panel of each of one or more groups within the area of the communication failure; and a step in the detection stage of determining that a communication failure has occurred in all monitoring panels within the group to which the representative monitoring panel belongs, if a communication failure in the representative monitoring panel is detected.
[0008] The remote monitoring center disclosed herein is a remote monitoring center connected to a monitoring panel that monitors equipment, and is equipped with a memory that stores a program and a processor that executes the program. In a learning stage, the processor acquires information representing the area of communication failure, detects whether or not there is a communication failure in one or more monitoring panels within the area of communication failure, registers a group consisting of one or more monitoring panels in which a communication failure has occurred, and determines one monitoring panel within the group to be a representative. In a detection stage, the processor acquires information representing the area of communication failure, detects whether or not there is a communication failure in the representative monitoring panel of each of the one or more groups within the area of communication failure, and if a communication failure in the representative monitoring panel is detected, determines that a communication failure has occurred in all monitoring panels within the group to which the representative monitoring panel belongs. [Effects of the Invention]

[0011] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 FIG. 1 is a diagram showing the configuration of a monitoring system. The monitoring system comprises a remote monitoring center 1, a base station group BSG, multiple pieces of equipment 2, and multiple monitoring panels 3. The monitoring panel 3 monitors the equipment 2 in buildings BL1, BL2, ..., BLN. The equipment 2 includes air conditioners, elevators, etc. The base station group BSG comprises multiple base stations. The monitoring panel 3 and the remote monitoring center 1 can communicate via any of the base stations included in the base station group BSG.
[0012] 2 is a diagram showing the configuration of the remote monitoring center 1. The remote monitoring center 1 includes a processor 11, a memory 12, and a communication circuit 13.
[0013] The communication circuit 13 communicates with the monitoring panel 3 via the base station. The memory 12 stores programs used by the processor 11.
[0014] Processor 11 executes a program in memory 12. In the learning stage, processor 11 acquires information indicating the area of the communication failure, detects whether or not there is a communication failure in one or more monitoring panels 3 within the area of the communication failure, registers a group consisting of one or more monitoring panels 3 in which a communication failure has occurred, and determines one monitoring panel 3 within the group to be the representative. In the detection stage, processor 11 acquires information indicating the area of the communication failure, detects whether or not there is a communication failure in the representative monitoring panel 3 of each of one or more groups within the area of the communication failure, and if a communication failure in the representative monitoring panel 3 is detected, determines that a communication failure has occurred in all monitoring panels 3 within the group to which the representative monitoring panel 3 belongs.
[0015] 3 is a diagram showing the configuration of the monitoring panel 3. The monitoring panel 3 includes a processor 21, a memory 22, and a communication circuit 23.
[0016] The communication circuit 23 communicates with the remote monitoring center 1 via a base station. The memory 22 stores programs used by the processor 21.
[0017] The processor 21 executes a program in the memory 22. The processor 21 receives an inquiry signal from the remote monitoring center 1, checks the communication status, and transmits a response signal to the remote monitoring center 1.
[0018] FIG. 4 is a flowchart showing a processing procedure of the communication failure detection method according to the first embodiment. In step S101, if the processor 11 of the remote monitoring center 1 acquires communication failure occurrence information via the communication circuit 13 during the learning stage, the process proceeds to step S102. The processor 11 of the remote monitoring center 1 can acquire the communication failure occurrence information by accessing the web page of a telecommunications carrier or by receiving an email from the telecommunications carrier. FIG. 5 is a diagram showing an example of communication failure occurrence information in the first embodiment. The communication failure occurrence information includes a future time period in which the communication failure will occur, an area in which the communication failure will occur, and the cause of the communication failure.
[0019] In step S102, in the learning stage, the processor 11 of the remote monitoring center 1 learns a group of one or more monitoring panels 3 in which a communication failure occurs.
[0020] In step S103, if learning has been performed using sufficient data, the learning is terminated and the process proceeds to step S104. If learning has not been terminated, the process returns to step S101.
[0021] In step S104, if the processor 11 of the remote monitoring center 1 acquires information about the occurrence of a communication failure through the communication circuit 13 during the detection stage, the process proceeds to step S105.
[0022] In step S105, in the detection stage, the processor 11 of the remote monitoring center 1 determines the monitoring panel 3 in which a communication failure occurs according to the learning result.
[0023] FIG. 6 is a flowchart showing the procedure of step S102. In step S201, the processor 11 of the remote monitoring center 1 identifies an area where a communication failure has occurred based on the acquired information on the occurrence of a communication failure.
[0024] In step S202, the processor 11 of the remote monitoring center 1 identifies one or more monitoring panels 3 located in the area where the communication failure has occurred. It is assumed that N (N is a natural number equal to or greater than 1) monitoring panels 3 have been identified.
[0025] In step S203, the processor 11 of the remote monitoring center 1 checks the communication status of the N monitoring panels 3 during the time period in which the communication failure occurred, which is included in the acquired communication failure occurrence information.
[0026] In step S204, the processor 11 of the remote monitoring center 1 registers a group of one or more monitoring panels 3 in which a communication failure has occurred. That is, the remote monitoring center 1 groups one or more monitoring panels 3 in which a communication failure has occurred.
[0027] In step S205, the processor 11 of the remote monitoring center 1 determines one monitoring panel 3 in the group as the representative of the group. The processor 11 of the remote monitoring center 1 updates the grouping table.
[0028] FIG. 7 is a diagram showing an example of grouping of the monitoring panel 3. In FIG. In an area (SSSS Prefecture), multiple monitoring panels 3 where a communication failure was detected during a certain communication failure time period are grouped into group G1, and multiple monitoring panels 3 where a communication failure was detected during a different communication failure time period are grouped into group G2. The representative of group G1 is monitoring panel R1, and the representative of group G2 is monitoring panel R2. Since the cause of the communication failure in the monitoring panels 3 is thought to be a malfunction in the base station, it can be determined that all monitoring panels 3 belonging to one group are communicating with the same base station.
[0029] FIG. 8 is a diagram showing an example of a grouping table for monitoring panels 3. In an area (SSSS Prefecture), the IDs of the monitoring panels 3 belonging to each group and the ID of the representative monitoring panel 3 are defined. FIG. 9 is a diagram showing an example of a grouping table for monitoring panels 3. In an area (TTTT Prefecture), the IDs of the monitoring panels 3 belonging to each group and the ID of the representative monitoring panel 3 are defined.
[0030] FIG. 10 is a flowchart showing the procedure of step S203 in the first embodiment. In step S401, if the time period in which a communication failure occurs has arrived, the process proceeds to step S402.
[0031] In step S402, the processor 11 of the remote monitoring center 1 selects one of the N monitoring panels 3 identified in step S202.
[0032] In step S403, the processor 11 of the remote monitoring center 1 transmits an inquiry signal to the selected monitoring panel 3 to inquire about the current communication status.
[0033] In step S404, the processor 21 of the monitoring panel 3 receives the inquiry signal.
[0034] In step S405, the processor 21 of the monitoring panel 3 checks whether the current communication status is normal or abnormal. An abnormality means that reception of signals from the base station or transmission of signals to the base station is completely or partially blocked.
[0035] In step S406, the processor 21 of the monitoring panel 3 transmits to the remote monitoring center 1 a response signal indicating the current communication status.
[0036] In step S407, if the processor 11 of the remote monitoring center 1 receives a response signal indicating that the communication status is normal, the process proceeds to step S408. If the remote monitoring center 1 receives a response signal indicating that the communication status is abnormal, or if no response signal is received, the process proceeds to step S409.
[0037] In step S408, the processor 11 of the remote monitoring center 1 determines that the communication status of the selected monitoring panel 3 is normal.
[0038] In step S409, the processor 11 of the remote monitoring center 1 determines that the communication status of the selected monitoring panel 3 is experiencing a communication failure.
[0039] In step S410, if all of the N monitoring panels 3 identified in step S202 have been selected, the process ends, and if any remain unselected, the process returns to step S402.
[0040] FIG. 11 is a flowchart showing the procedure of step S105. In step S301, the processor 11 of the remote monitoring center 1 identifies an area where a communication failure has occurred based on the information on the occurrence of a communication failure.
[0041] In step S302, the processor 11 of the remote monitoring center 1 refers to the grouping table to identify a representative monitoring panel 3 for each of one or more groups in the area where the communication failure has occurred. Assume that M (M is a natural number equal to or greater than 1) representative monitoring panels 3 have been identified.
[0042] In step S303, the processor 11 of the remote monitoring center 1 checks the communication status of the M representative monitoring panels 3 during the time period in which the communication failure occurred.
[0043] In step S304, the processor 11 of the remote monitoring center 1 determines that a communication failure has occurred in all monitoring panels 3 that belong to the group of the representative monitoring panel 3 in which a communication failure has occurred.
[0044] FIG. 12 is a flowchart showing the procedure of step S303 in the first embodiment. In step S501, if the time period in which a communication failure occurs has arrived, the process proceeds to step S502.
[0045] In step S502, the processor 11 of the remote monitoring center 1 selects one of the M representative monitoring panels 3 identified in step S302.
[0046] In step S503, the processor 11 of the remote monitoring center 1 transmits an inquiry signal to the selected representative monitoring panel 3 to inquire about the current communication status.
[0047] In step S504, the processor 21 of the monitoring panel 3 receives the inquiry signal.
[0048] In step S505, the processor 21 of the monitoring panel 3 checks whether the current communication status is normal or abnormal.
[0049] In step S506, the processor 21 of the monitoring panel 3 transmits to the remote monitoring center 1 a response signal indicating the current communication status.
[0050] In step S507, if the processor 11 of the remote monitoring center 1 receives a response signal indicating that the communication status is normal, the process proceeds to step S508. If the processor 11 of the remote monitoring center 1 receives a response signal indicating that the communication status is abnormal, or if no response signal is received, the process proceeds to step S509.
[0051] In step S508, the processor 11 of the remote monitoring center 1 determines that the communication status of the selected representative monitoring panel 3 is normal.
[0052] In step S509, the processor 11 of the remote monitoring center 1 determines that a communication failure has occurred in the communication status of the selected representative monitoring panel 3.
[0053] In step S510, if all of the M representative monitoring panels 3 identified in step S302 have been selected, the process ends, and if any remain unselected, the process returns to step S502.
[0054] As described above, according to this embodiment, after forming a group of monitoring panels, it is possible to determine whether or not there is a communication failure in all monitoring panels in the group simply by detecting whether or not there is a communication failure in the representative monitoring panel of the group, so that monitoring panels in which communication failures occur can be detected with a low communication frequency.
[0055] Embodiment 2 13 is a diagram illustrating an example of communication failure occurrence information according to Embodiment 2. The communication failure occurrence information includes past time periods in which communication failures occurred, areas in which communication failures occurred, and causes of communication failures.
[0056] FIG. 14 is a flowchart showing the procedure of step S203 in the second embodiment. In step S402, the processor 11 of the remote monitoring center 1 selects one of the N monitoring panels 3 identified in step S202.
[0057] In step S603, the processor 11 of the remote monitoring center 1 transmits to the selected monitoring panel 3 an inquiry signal inquiring about the communication status during the time period in which a past communication failure occurred.
[0058] In step S604, the processor 21 of the monitoring panel 3 receives the inquiry signal.
[0059] In step S605, the processor 21 of the monitoring panel 3 checks the communication status during the time period when a communication failure occurred in the past by referring to the communication log or the like.
[0060] In step S406, the processor 21 of the monitoring panel 3 transmits to the remote monitoring center 1 a response signal indicating the communication status during the time period in which the past communication failure occurred.
[0061] In step S407, if the processor 11 of the remote monitoring center 1 receives a response signal indicating that the communication status is normal, the process proceeds to step S408. If the processor 11 of the remote monitoring center 1 receives a response signal indicating that the communication status is abnormal, or if no response signal is received, the process proceeds to step S409.
[0062] In step S408, the processor 11 of the remote monitoring center 1 determines that the past communication status of the selected monitoring panel 3 was normal.
[0063] In step S409, the processor 11 of the remote monitoring center 1 determines that the past communication status of the selected monitoring panel 3 has a communication failure.
[0064] In step S410, if all of the N monitoring panels 3 identified in step S202 have been selected, the process ends, and if any remain unselected, the process returns to step S402.
[0065] As described above, according to this embodiment, it is possible to learn the group of monitoring panels using information on occurrence of past communication failures.
[0066] Embodiment 3 FIG. 15 is a flowchart showing the procedure of step S203 in the third embodiment.
[0067] In step S401, if the time period in which a communication failure occurs has arrived, the process proceeds to step S402.
[0068] In step S402, the processor 11 of the remote monitoring center 1 selects one of the N monitoring panels 3 identified in step S202.
[0069] In step S706, the processor 21 of the monitoring panel 3 periodically transmits a communication status signal indicating the current communication status, that is, at regular time intervals.
[0070] In step S707, if the processor 11 of the remote monitoring center 1 receives a communication status signal indicating that the communication status is normal from the selected monitoring panel 3, the process proceeds to step S408. If the processor 11 of the remote monitoring center 1 receives a communication status signal indicating that the communication status is abnormal from the selected monitoring panel 3, or if no communication status signal is received from the selected monitoring panel 3, the process proceeds to step S409.
[0071] In step S408, the processor 11 of the remote monitoring center 1 determines that the communication status of the selected monitoring panel 3 is normal.
[0072] In step S409, the processor 11 of the remote monitoring center 1 determines that the communication status of the selected monitoring panel 3 is experiencing a communication failure.
[0073] In step S410, if all of the N monitoring panels 3 identified in step S202 have been selected, the process ends, and if any remain unselected, the process returns to step S402.
[0074] FIG. 16 is a flowchart showing the procedure of step S303 in the third embodiment. In step S501, if the time period in which a communication failure occurs has arrived, the process proceeds to step S502.
[0075] In step S502, the processor 11 of the remote monitoring center 1 selects one of the M representative monitoring panels 3 identified in step S302.
[0076] In step S806, the processor 21 of the representative monitoring panel 3 of the group periodically transmits a communication status signal indicating the current communication status, that is, at regular time intervals.
[0077] In step S807, if the processor 11 of the remote monitoring center 1 receives a communication status signal indicating that the communication status is normal from the selected monitoring panel 3, the process proceeds to step S508. If the processor 11 of the remote monitoring center 1 receives a communication status signal indicating that the communication status is abnormal from the selected monitoring panel 3, or if no communication status signal is received from the selected monitoring panel 3, the process proceeds to step S509.
[0078] In step S508, the processor 11 of the remote monitoring center 1 determines that the communication status of the selected representative monitoring panel 3 is normal.
[0079] In step S509, the processor 11 of the remote monitoring center 1 determines that a communication failure has occurred in the communication status of the selected representative monitoring panel 3.
[0080] In step S510, if all of the M representative monitoring panels 3 identified in step S302 have been selected, the process ends, and if any remain unselected, the process returns to step S502.
[0081] As described above, according to this embodiment, a communication failure in the monitoring panel can be detected by the communication status signal periodically transmitted from the monitoring panel.
[0082] Embodiment 4 Fig. 17 is a flowchart showing the processing steps of a communication failure detection method according to the embodiment 4. The flowchart in Fig. 17 differs from the flowchart in Fig. 4 according to the embodiment 1 in that the flowchart in Fig. 17 includes steps S906 to S909.
[0083] In step S906, if the monitoring panel 3 in which the communication failure occurs is monitoring a facility that is the target of constant monitoring, the process proceeds to step S907.
[0084] In step S907, the processor 11 of the remote monitoring center 1 selects a worker to be dispatched to the site where the equipment to be constantly monitored is located, according to the worker table. FIG. 18 is a diagram showing an example of the worker table. The worker table defines the status and characteristics of the worker. For example, the worker table also includes information such as whether the worker is currently working, a code indicating the worker's current location, and a number of equipment management skills. Equipment management skills include skills for inspecting electrical systems and skills for inspecting mechanical systems.
[0085] In step S908, the processor 11 of the remote monitoring center 1 determines whether the communication failure in the monitoring panel 3 has been restored.
[0086] In step S909, the processor 11 of the remote monitoring center 1 notifies the mobile terminal carried by the worker dispatched to the site of the recovery from the communication failure.
[0087] FIG. 19 is a flowchart showing the procedure of step S907. In step S921, in the restoration detection stage, the processor 11 of the remote monitoring center 1 selects a representative monitoring panel 3 of the group of monitoring panels 3 that monitor the equipment that is the object of constant monitoring.
[0088] In step S922, during the recovery detection stage, the processor 11 of the remote monitoring center 1 transmits an inquiry signal to the selected representative monitoring panel 3 to inquire about the current communication status.
[0089] In step S923, during the recovery detection stage, the processor 21 of the monitoring panel 3 receives an inquiry signal.
[0090] In step S924, in the recovery detection stage, the processor 21 of the monitoring panel 3 checks whether the current communication status is normal or abnormal.
[0091] In step S925, during the recovery detection stage, the monitoring panel 3 transmits to the remote monitoring center 1 a response signal indicating the current communication status.
[0092] In step S926, if the processor 11 of the remote monitoring center 1 receives a response signal indicating that the communication status is normal, the process proceeds to step S927. If the remote monitoring center 1 receives a response signal indicating that the communication status is abnormal, or if no response signal is received, the process proceeds to step S928.
[0093] In step S927, in the recovery detection stage, the processor 11 of the remote monitoring center 1 determines that the communication status of all monitoring panels 3 within the group of the selected representative monitoring panel 3 has been recovered.
[0094] In step S928, during the recovery detection stage, the processor 11 of the remote monitoring center 1 determines that the communication failure has not been recovered from for all monitoring panels 3 in the group of the selected representative monitoring panel 3. This makes it possible to determine whether the monitoring panel 3 monitoring the equipment that is the target of constant monitoring has recovered from the communication failure.
[0095] As described above, according to this embodiment, when a communication failure occurs in a monitoring panel that is the subject of constant monitoring, it is possible to dispatch an appropriate worker to the site, and also to notify the on-site worker of recovery from the communication failure.
[0096] In the above embodiment, the recovery of the communication status of the representative monitoring panel 3 of the group of monitoring panels 3 that monitor the equipment that is the target of constant monitoring was checked, but this is not limited to this.
[0097] The recovery of the communication status of the monitoring panel 3 that monitors the equipment that is the subject of constant monitoring may also be inspected.
[0098] It is also possible to check the recovery of the communication status of the representative monitoring panel 3 of all groups in the area where the communication failure occurred. That is, in the recovery detection stage, recovery from the communication failure of the representative monitoring panel 3 of each group in which a communication failure occurred is detected, and when recovery from the communication failure of the representative monitoring panel 3 is detected, it may be determined that all monitoring panels 3 in the group to which the representative monitoring panel 3 belongs have recovered from the communication failure.
