Japanese Patent No. 6100239 Japanese Patent No. 5389229

  Incidentally, in recent years, with the spread of elevators, the management server is required to diagnose and monitor a large number of elevators. Further, in recent years, when a failure or modulation occurs in an elevator, remote control or remote recovery for changing the control of the elevator by a command from a management server has been performed. For this reason, there are a wide variety of commands transmitted from the management server, and the number of commands has become very large. If all the response results of the elevators to such a wide variety of commands are transmitted to the monitoring center, it is necessary to enlarge the receiving terminal of the monitoring center and increase the number of monitoring personnel.

  On the other hand, when the diagnostic operation is executed in response to a command from the management server, there are almost no cases where there is no abnormality in the diagnostic result. It is sufficient that such a diagnosis result without abnormality is stored in the management server for elevator maintenance, and there is little need to receive and check at the monitoring center. On the other hand, the diagnosis result of the failure or abnormality of the elevator is immediately received and confirmed at the monitoring center, and it is necessary to contact an elevator management company or the like, or dispatch a technician. In this case, when the elevator management company is contacted via the monitoring center, there may be a delay in communication of failure or abnormality. As described above, when the destination of data from the elevator is only the monitoring center, unnecessary information may be transmitted to the monitoring center. On the other hand, if necessary information may not be transmitted to a required location, Transmission / reception may become inefficient and deteriorate the quality of the elevator maintenance management service.

  Further, when the management server performs diagnosis and monitoring of a large number of elevators, transmission of diagnosis results from each elevator to the management server may overlap. In this case, if the amount of transmission data exceeds the communication capacity of the management server, diagnosis result data cannot be received, and the quality of the elevator maintenance management service may be degraded.

  Accordingly, an object of the present invention is to improve the quality of elevator maintenance management services.

The elevator remote monitoring system according to the present invention includes an operation control of the elevator and a control device that outputs a failure signal when a failure occurs in the elevator, and a storage unit, and is connected to the control device to control the control. A monitoring device that exchanges data with a device and receives the failure signal; a management server that is connected to the monitoring device via a communication network and exchanges data with the monitoring device; The communication board is connected to the monitoring board or the portable terminal through a line different from the first line and the first line connected to the management server. and a second line that is, wherein the monitoring device, when receiving the diagnosis operation command of the elevator from the management server, diagnostic luck to the controller Outputs a command to cause the control device to execute diagnostic operation, receives diagnostic operation result data from the control device, stores the data in the storage unit, and receives diagnostic operation result data received from the control device or input from the control device On the basis of the failure signal, the name of the building where the elevator is installed, the management number of the elevator, the item whose diagnosis result is abnormal, or the elevator status code indicating the failure state of the elevator included in the failure signal When the elevator operation information indicating the state of the elevator is generated in combination and an abnormal item is included in the diagnostic operation result data received from the control device, or the failure signal is input from the control device the originating the elevator status information to the monitoring panel or the portable terminal by the second line The control when the diagnostic operation result data received are all normal from the device, the management at the time for which the diagnosis operation result data transmission request from the server, made the transmission request diagnostic operation result the data first The management server is connected to the plurality of monitoring devices via the communication network, and the diagnostic operation result data transmitted from the monitoring device is transmitted among the plurality of monitoring devices. It is characterized in that a request for transmission of diagnostic operation result data is sent to each of the monitoring devices so as not to receive from two or more simultaneously.

In this way, since the diagnostic operation result data received from the control device or the failure signal input from the control device, the elevator server transmits information on the elevator status to the information processing device identified from the management server, the monitoring panel, and the mobile terminal . management server, and monitoring panel, in the mobile terminal, suppresses the reception of unnecessary information, it is possible to speed up the information connection of necessary information. More specifically, if an abnormal item is included in the diagnostic operation result data or a failure signal is input, the elevator status is displayed on the monitoring panel of the monitoring center or the elevator administrator's mobile terminal that requires elevator status information. Sending information to speed up information communication, and if all diagnostic operation result data is normal, do not send the elevator status information to the monitoring panel of the monitoring center and the mobile terminal of the elevator administrator Since the elevator state information is transmitted only to the server, it is possible to suppress unnecessary information from being transmitted to the monitoring panel and the portable terminal. Furthermore, when the diagnosis operation of the elevator is executed, the diagnosis operation result data is stored in the storage unit of the monitoring device connected to the elevator control device, and the diagnosis operation result data is managed according to the transmission request from the management server. Since it transmits to a server, it can control that diagnostic operation result data is simultaneously transmitted to a management server from many elevators, and a management server cannot receive diagnostic operation result data. Further, by causing the elevator to perform a diagnostic operation in accordance with a diagnostic operation command from the management server, a diagnostic operation can be performed as necessary. This makes it possible to improve the quality of the elevator maintenance management service by improving the efficiency of transmission and reception of elevator information.

When there is a modulation item in the diagnostic operation result data received by the monitoring device 250, the specific information processing device is the monitoring panel 330 indicated by reference signs A and D and the maintenance terminal 500 shown in FIG. Furthermore, when all of the diagnostic operation result data received by the monitoring device 250 are normal and there are no abnormal items, the specific information processing device is the monitoring panel 330 indicated by reference characters C and D, and the maintenance terminal 500 shown in FIG. Details will be described in the description of the operation of the remote monitoring systems 100 and 110.

  FIG. 4 is an elevator state information list 376 showing an example of elevator state information transmitted by the monitoring device 250 according to the state of the elevator 20. As shown in FIG. 4, the elevator status information includes “AAA Building No. 1 Door Unopenable”, “AAA Building No. 1 Door Open / Close Diagnosis Abnormal”, “AAA Building No. 1 Door Open / Close Diagnosis Modulation”, “AAA Building No. 1 Diagnosis” It is a short message such as “Normal end”. Details will be described in the description of the operation of the remote monitoring systems 100 and 110.

  Next, the operation of the remote monitoring system 100 for the elevator 20 shown in FIG. 1 will be described with reference to FIGS. 5 to 10, the control device 200 will be described as executing a diagnostic operation according to a predetermined schedule.

  As shown in step S101 of FIGS. 5 and 6, the control device 200 of the elevator 20 determines whether or not it is a diagnostic operation start time zone based on a predetermined schedule. Then, for example, when a predetermined diagnostic operation time zone such as once a month is reached, the process proceeds to step S102 in FIG. 6 to determine whether or not the elevator 20 can perform the diagnostic operation. This determination is made, for example, based on whether the door of the car 22 is closed, whether the car 22 is stopped, the weight sensor of the car 22, the camera in the car 22, the human sensor in the car 22 or the like. It is confirmed whether or not there are passengers inside the basket 22. When the door of the car 22 is open, the car 22 is moving, or there are passengers in the car 22, the control device 200 determines NO in step S102 of FIG. If it is not determined that the diagnostic operation is possible during the diagnostic operation start time zone, for example, the diagnostic operation time zone may be reset on the next day. When it is confirmed that the door of the car 22 is closed, the car 22 is stopped, and there are no passengers in the car 22, the control device 200 determines YES in step S102 of FIG. Proceeding to step S103, a diagnostic operation is executed.

  In the diagnostic operation, each device of the elevator 20 is diagnosed by performing an operation different from the normal operation state. In the remote monitoring system 100 for the elevator 20 according to the present embodiment, diagnosis items such as driving performance, braking performance, door opening / closing, and emergency power battery are diagnosed, and diagnostic operation result data 381 as shown in FIG. ~ 383 are output. The diagnosis operation result data 381 to 383 have the same data format as the diagnosis history data 372 shown in FIG. 2 and include items such as an elevator management number, diagnosis execution date and time, diagnosis mode, diagnosis item, and diagnosis result. FIG. 10 shows three pieces of diagnostic operation result data 381 to 383 output as a result of three diagnostic operations. In FIG. 7, OK, NG, and A1 of each diagnosis result indicate a case where the diagnostic item is normal, abnormal, or modulated as a result of the diagnostic operation.

  In the diagnosis of driving performance, the control device 200 moves the basket 22 of the elevator 20 shown in FIG. 1 to a predetermined floor and detects the presence of acceleration, abnormal noise, and the like by various sensors attached to the elevator 20. When the acceleration is within a predetermined range and no abnormal noise is recognized, a diagnosis result of OK is input for the driving performance. When the acceleration exceeds a predetermined range or abnormal noise is recognized, NG is input as the diagnosis result of the driving performance.

  Further, regarding the brake performance, the control device 200 creates a state in which the car 22 of the elevator 20 is equivalent to being full, releases one of the two brakes, and diagnoses whether the car 22 can be held stationary with one brake. To do. If both the brakes are full, even if the cage 22 is full, if the cage 22 can be held stationary with only one brake, OK is input to the diagnosis result of the brake performance. On the other hand, when the basket 22 cannot be held stationary with only one brake, NG is input to the diagnosis result of the brake performance. As for door opening and closing, the door 26 is opened and closed on each floor with the opening / closing driving force of the door 26 being reduced from the normal level, and the presence / absence of foreign matter mixing into the sill of the cage 22 is diagnosed from the door opening and closing time at that time. To do. If the opening / closing takes longer than normal, NG is entered in the door opening / closing diagnosis result with the presence of foreign matter, and if the opening / closing time is the same as normal, the door opening / closing diagnosis result is OK without foreign matter mixing. Entered. For the emergency power battery, the voltage is checked. If there is no voltage drop, OK is input to the diagnosis result of the emergency power battery, and NG is input to the diagnosis result if the voltage is low. .

  In addition, in each diagnosis item, although there is a variation from a normal numerical value, if the abnormality determination threshold value is not reached, A1 is input to the diagnosis result of each diagnosis item as being modulated.

  When the execution of the diagnostic operation in step S103 in FIG. 6 is completed, the control device 200 proceeds to step S104 in FIG. 6 and outputs diagnostic operation result data to the monitoring device 250 (see FIG. 5).

  As shown in step S <b> 110 of FIG. 7, the monitoring device 250 determines whether diagnostic operation result data is input from the control device 200. When the diagnostic operation result data is input from the control device 200, the process proceeds to step S111 in FIG. 7 to accept the diagnostic operation result data and proceeds to step S112 in FIG. 7, and (1) the diagnostic result column of the diagnostic operation result data (2) Whether there is a modulation item in which A1 is input but there is no item in which NG is input in the diagnosis result column of the diagnostic operation result data, (3) All OK is entered in the diagnostic result column of the diagnostic operation result data, and it is confirmed whether all items are normal.

  Then, the monitoring device 250 proceeds to step S113 in FIG. 7 and combines the above confirmation result, the installation location and name of the elevator 20, and the diagnostic item whose diagnostic result is abnormal as shown in FIG. Elevator status information is generated. For example, when NG is entered in the door opening / closing diagnosis item as in the diagnostic operation result data 382 shown in FIG. 10, as shown in the elevator state information list 376 in FIG. Elevator state information such as “open / close diagnosis abnormality” is generated. In addition, as shown in the diagnosis operation result data 383 shown in FIG. 10, when A1 is input in the door opening / closing diagnosis item, as shown in the elevator state information list 376 of FIG. Elevator state information such as “open / close diagnostic modulation” is generated. In addition, as shown in the diagnosis operation result data 381 shown in FIG. 10, when OK is input to all the diagnosis items, as shown in the elevator state information list 376 of FIG. Elevator state information such as “End” is generated.

  Then, the monitoring device 250 proceeds to step S114 in FIG. 7, specifies the specific information processing device with reference to the destination table 375 shown in FIG. 3, and specifies the elevator state information generated in step S113 in FIG. Call the device.

  In step S114 of FIG. 7, the monitoring device 250 refers to the destination table 375 shown in FIG. 3 when there is an abnormal item for which NG is input in the (1) diagnosis result column of the diagnostic operation result data. Then, the monitoring panel 330 and the portable terminal 411 of the elevator manager 410 are specified as the specific information processing apparatus, and the elevator state information is transmitted to the monitoring panel 330 and the portable terminal 411. Also, (2) when there is no item in which NG is input in the diagnosis result column of the diagnostic operation result data but there is a modulation item in which A1 is input, refer to the destination table 375 shown in FIG. Thus, the monitoring board 330 is specified as the specific information processing apparatus, and the elevator state information is transmitted to the monitoring board 330. Also, (3) when all the OKs are entered in the diagnostic result column of the diagnostic operation result data and all items are normal, the management server 360 is referred to with reference to the destination table 375 shown in FIG. Is identified as the specific information processing apparatus, and elevator state information is transmitted to the management server 360. At this time, the communication unit 270 of the monitoring device 250 exchanges data with the communication network 30 according to the communication standard of the first country.

  As in the cases (1) and (2) above, elevator status information such as “AAA Building No. 1 Door Open / Close Diagnosis Abnormal” and “AAA Building No. 1 Door Open / Close Diagnosis Modulation” is displayed on the monitoring panel 330 of the monitoring center 310. When input, the information is displayed on the display 331. When this signal is displayed, the monitor 334 communicates with the elevator administrator 410 whose elevator status information is transmitted to the portable terminal 411, and sends the engineer 350 from the service center 340 installed in the first country. Dispatch to elevator 20 installed in one country. In the case of (3), nothing is displayed on the monitoring panel 330 of the monitoring center 310, and the diagnosis history data 372 of the maintenance database 370 of the management server 360 is updated.

  When the transmission of the elevator state information is completed, the monitoring device 250 proceeds to step S115 shown in FIG. 7 and stores the diagnostic operation result data in the storage unit 260.

  When the diagnostic operation result data is stored in the storage unit 260, the monitoring device 250 determines whether there is a request for transmission of the diagnostic operation result data from the management server 360, as shown in step S120 of FIG. Then, as shown in FIG. 5, when there is a transmission request for diagnostic operation result data from the management server 360, the process proceeds to step S <b> 121 in FIG. 8, and the diagnostic operation result data is transmitted to the management server 360. At this time, the communication unit 270 of the monitoring device 250 exchanges data with the communication network 30 according to the communication standard of the first country.

  As illustrated in FIG. 5, when the management server 360 receives the diagnostic operation result data from the monitoring device 250, the management server 360 stores the data in the diagnostic history data 372 of the maintenance database 370.

  Further, the monitoring device 250 determines whether or not a failure signal has been input from the control device 200, as shown in step S150 of FIGS. Then, when a failure signal is input from the control device 200, as shown in step S151 of FIG. 9, the failure signal from the control device 200 is accepted, and the content of the failure signal is confirmed in step S152.

  The failure signal is, for example, a combination of the failure code and the elevator status code described with reference to FIG. When the monitoring device 250 receives a failure signal including a failure code 0001 indicating a failure in opening and closing the doors 13 and 26 and an elevator status code “door cannot be opened” from the control device 200, the monitoring device 250 performs step S153 in FIG. , The elevator location information such as “AAA Building No. 1 Door Unopenable” as shown in FIG. 4 is generated by combining the installation location and name of the elevator 20. Then, the monitoring device 250 proceeds to step S154 shown in FIG. 9, specifies the specific information processing device as the monitoring panel 330 and the portable terminal 411 of the elevator manager 410 with reference to the destination table 375 shown in FIG. Elevator state information is transmitted to the monitoring panel 330 and the portable terminal 411.

  When elevator state information due to the occurrence of a failure is input to the monitoring panel 330 of the monitoring center 310, the information is displayed on the display 331. When this signal is displayed, the monitor 334 communicates with the elevator administrator 410 whose elevator status information is transmitted to the portable terminal 411, and sends the engineer 350 from the service center 340 installed in the first country. Dispatch to elevator 20 installed in one country.

  As described above, the remote monitoring system 100 for the elevator 20 according to the present embodiment has the elevator state information when the diagnostic operation result data includes an abnormal item, a modulation item, or when a failure signal is input. The elevator status information can be transmitted to the necessary monitoring panel 330 of the monitoring center 310 or the portable terminal 411 of the elevator manager 410 to speed up information communication. When all the diagnostic operation result data are normal, the elevator status information is not transmitted to the monitoring panel 330 of the monitoring center 310 and the portable terminal 411 of the elevator manager 410, and only the management server 360 is informed of the elevator status information. Therefore, it is possible to suppress unnecessary information from being transmitted to the monitoring panel 330 and the portable terminal 411.

  That is, the remote monitoring system 100 for the elevator 20 according to the present embodiment is a specific information processing apparatus identified from the information processing apparatus according to the diagnostic operation result data received from the control apparatus 200 or the failure signal input from the control apparatus 200. Since the elevator status information is transmitted to each information processing device, it is possible to suppress the reception of unnecessary information in each information processing device and to transmit necessary information to the specific information processing device to speed up information communication. Thereby, transmission / reception of the information of the elevator 20 can be made efficient, and the quality of the maintenance management service of the elevator 20 can be improved.

  Further, when the diagnosis operation of the elevator 20 is executed, the diagnosis operation result data is stored in the storage unit 260 of the monitoring device 250 connected to the control device 200 of the elevator 20, and in response to a transmission request from the management server 360. Since the diagnostic operation result data is transmitted to the management server 360, it is possible to prevent the diagnosis operation result data from being simultaneously transmitted from the multiple elevators 20 to the management server 360 and the management server 360 from receiving the diagnostic operation result data. Further, by causing the elevator 20 to execute a diagnostic operation in accordance with a diagnostic operation command from the management server 360, it is possible to perform a diagnostic operation as necessary. Thereby, the quality of the maintenance management service of the elevator 20 can be improved.

  Furthermore, in the remote monitoring system 100 of the embodiment shown in FIG. 1, the communication line that connects the communication unit 270 of the monitoring device 250 to the management server 360 via the communication network 30 and the communication device 325 is defined as the first line. A communication line connecting the communication unit 270 of 250, the communication network 30, and the monitoring center 310 and the portable terminal 411 via the communication device 320 may be configured as a second line different from the first line.

  As described above, by making the first line between the management server 360 and the second line between the monitoring center 310 and the mobile terminal 411 separate, the diagnostic operation result data is being transmitted to the management server 360. Information on occurrence of an abnormality, failure, etc. can be transmitted to the monitoring panel 330 of the monitoring center 310 and the portable terminal 411 through a second line different from the first line. As a result, it is possible to suppress a situation where the communication line is occupied due to the transmission of the diagnostic operation result data to the management server 360 and information such as an abnormality or failure cannot be transmitted to the monitoring panel 330 and the portable terminal 411.
