Description

  The present invention relates to a remote monitoring system that remotely monitors lifting devices such as elevators and escalators.

  2. Description of the Related Art Conventionally, a remote monitoring system that monitors the operating status of an elevator such as an elevator has been provided. The remote monitoring system includes an elevator including a control microcomputer for controlling the operation, and a monitoring terminal that is communicably connected to the elevator control microcomputer and remotely monitors the operation of the elevator (Patent Document 1). reference).

  On the other hand, specification data is stored in the control microcomputer, and the specification of the elevator can be changed by changing the specification data. For example, by changing the specification data of the control microcomputer, it is possible to change the specifications of the elevator, such as changing the rated speed, controlling the on / off of the air conditioning fan in the car, and adjusting the volume of the speaker installed in the car. .

  By the way, if the specification data of the control microcomputer is changed, an unexpected abnormality may occur in the operation of the elevator. Therefore, the specification data of the control microcomputer is changed to a local engineer (elevator whose specification data is to be changed). Thus, it is performed after confirming that there is no user in the elevator (for example, after confirming that the car is unmanned (empty car state)). As described above, when changing the specification data of the control microcomputer, it was troublesome because the engineer was dispatched to the site to deal with the situation so that the user would not be affected by this change.

FIG. 1 is a block diagram of an elevator remote monitoring system according to an embodiment of the present invention. FIG. 2 is a block diagram of an elevator remote monitoring system according to a modification of the present invention.

  Hereinafter, a remote monitoring system for an elevator apparatus according to the present invention (hereinafter simply referred to as a remote monitoring system) will be described. The remote monitoring system is, for example, a system that remotely monitors the operation status of an elevator. In this remote monitoring system, for example, the elevator outputs an abnormality signal when an abnormality such as operation stop occurs, and based on this abnormality signal, the monitoring terminal connected to the elevator performs notification regarding the abnormality of the elevator. By performing such notification, a supervisor who is monitoring the monitoring terminal can send a technician to the site (an elevator in which an abnormality has occurred). The engineer who arrives at the site may respond to the abnormality of the elevator by changing the specification of the elevator (specification of the drive system, control specification of operation, etc.), for example. Specifically, a technician may deal with an elevator abnormality by changing the elevator specifications by rewriting data on the elevator specifications.

  On the other hand, there is also a request to change the specifications of the elevator from a place away from the elevator. In response to this request, in this remote monitoring system, when it can be determined that the car is unmanned based on information obtained from the elevator, the data related to the specification in the elevator is rewritten, and the data related to the specification is temporarily rewritten. Even if this happens, the elevator specifications can be changed while suppressing the impact on the user. In addition, although there exist an elevator, an escalator, etc. in a raising / lowering apparatus, below, the remote monitoring system of an elevator is demonstrated.

  As shown in FIG. 1, the remote monitoring system includes an elevator 2 having a control microcomputer 20 and a car 21, and a server (processing unit) 3 connected to at least the control microcomputer 20. The remote monitoring system 1 of this embodiment includes a technician terminal (terminal) 4 that can be connected to the server 3. The remote monitoring system 1 of the present embodiment includes a remote monitoring unit 5 and a monitoring terminal 6 provided between the control microcomputer 20 and the server 3.

  In FIG. 1, one monitoring terminal 6 is shown, but the remote monitoring system 1 of this embodiment includes a plurality of monitoring terminals 6. Moreover, since the elevator 2 is connected to each monitoring terminal 6 via the communication system R1, the remote monitoring system 1 of this embodiment includes a plurality of elevators. For example, the communication system R1 can communicate with the monitoring terminal 6 sequentially from the control microcomputer 20 via the remote monitoring unit 5 and the telephone line, and conversely from the monitoring terminal 6 via the telephone line and the remote monitoring unit 5. Thus, the communication system can communicate with the elevator 2. Moreover, although one engineer terminal 4 is shown in FIG. 1, the remote monitoring system 1 of this embodiment is provided with a plurality of engineer terminals.

  The car 21 of the elevator 2 is connected to the control microcomputer 20 and moves up and down in the hoistway. In the remote monitoring system 1 of the present embodiment, in the car 21, the operation of the elevator 2 and the buttons for opening and closing the car and opening / closing the car door by operation and the operation status of the elevator 2 are detected. And various sensors that can be output as signals relating to. The sensor can output various signals corresponding to the operation status of the elevator 2.

  The control microcomputer 20 of the elevator 2 always accepts output of information related to the operation status of the elevator 2 by a sensor (a sensor provided in the car 21). Further, when information is output from the sensor, the control microcomputer 20 performs, for example, a button operation in the car, car position information, car door opening / closing information, and a motor for raising and lowering the car based on the output information. Drive information and an event code indicating a power failure can be output. The event code includes an event code indicating a failure (an event code indicating an abnormality of the elevator 2 such as a failure of a car door or a landing door, an overrun of the car, or a life of a car light).

  In the remote monitoring system 1 of the present embodiment, the control microcomputer 20 includes a first storage unit (storage unit) 200 that stores data related to the specifications of the elevator 2 in a rewritable manner. In the remote monitoring system 1 of the present embodiment, the first storage unit 200 can be rewritten by the server 3. The specifications of the elevator 2 include a drive system specification and a control specification for operation. Specifically, the specifications of the elevator 2 include a rated speed, on / off control of an air conditioning fan in the car, and adjustment of a volume of a speaker provided in the car. Further, the data relating to the specification includes a program relating to the specification and numerical values used in the program.

  The remote monitoring unit 5 always accepts output of a signal from the control microcomputer 20 (for example, an event code related to button operation in the car or an event code indicating a failure), and when the signal is output from the control microcomputer 20. The signal and information related to the elevator from which the signal is output (for example, the elevator identification number (machine number) of the elevator 2) are output to the monitoring terminal 6. In the remote monitoring system 1 of the present embodiment, the remote monitoring unit 5 is configured such that when a later-described input request signal is output from the server 3, an event code indicating car door opening / closing information from the control microcomputer 20 and a button operation in the car. Is output to the server 3.

  For example, the monitoring terminal 6 of the present embodiment monitors a large number of elevators installed in a plurality of areas, and is installed in a monitoring center or the like that is a building apart from the target elevator. A supervisor (operator) is resident in the monitoring center of this embodiment. The monitoring terminal 6 is connected to the server 3 and can be connected to the technician terminal 4 via the Internet.

  The monitoring terminal 6 outputs information (for example, the machine number of the elevator 2) and signals related to the elevator that is the output source from the control microcomputer 20 via the communication system R1. The monitoring terminal 6 includes, for example, a second display unit 60 that can display information (for example, an elevator identification number) of the elevator 2 that is an output source and contents of a signal from the control microcomputer 20 (for example, an event code). The second display unit 60 is, for example, a display. Moreover, the monitoring terminal 6 has the 2nd input part 61 which can be operated by the monitoring person. The second input unit 61 is, for example, a keyboard.

  When the information (for example, elevator identification number) and the abnormality signal of the output source elevator 2 are output from the control microcomputer 20, the monitoring terminal 6 outputs the information (for example, elevator identification) of the output source elevator 2 on the second display unit 60. No.) and the contents of the abnormal signal (for example, an event code indicating an abnormality) are displayed to notify the monitoring staff of the abnormality related to the elevator 2. By checking this display, the monitoring person can grasp the abnormality of the elevator 2, operate the second input unit 61 as necessary, request the engineer to be dispatched, or remotely (the abnormality occurs Or a request at a location away from the elevator 2 that is located). In the remote monitoring system 1 of the present embodiment, when making such a request to the technician, the monitoring terminal 6 informs the technician terminal 4 of the information of the elevator 2 that is the output source (for example, for example) The elevator identification number) and the content of the abnormality signal (for example, an event code indicating abnormality) are also output.

  The engineer terminal 4 is a terminal such as a PDA (Personal Digital Assistant), a smartphone, or a laptop computer, and can communicate with the server 3 via the Internet. Further, the technician terminal 4 is possessed by a technician who can cope with the abnormality of the elevator 2.

  In the remote monitoring system 1 of the present embodiment, the technician terminal 4 receives information output from the monitoring terminal 6 (for example, information related to a seconding from the monitoring terminal 6 or a request for remote response) or information output from the server 3 ( For example, during operation after changing specification data, which will be described later, the contents of signals output from the control microcomputer 20 (for example, event codes) and the information of the elevator (elevating device) 2 that is the output source (for example, elevator identification numbers) And the 1st display part 40 which can display the notification from the server 3, etc., and the 1st input part 41 which can input specification information by the engineer The 1st display part 40 is a display, for example. The first input unit 41 is, for example, an input key, a keyboard, etc. When the technician terminal 4 includes a touch panel display, this display is the first display unit. Serving as a 0 and the first input unit 41.

  The specification information is information related to the specifications of the elevator 2 (specifications regarding the driving system and control specifications regarding the driving). Specifically, the specification information includes, for example, a change in rated speed, a change in acceleration when the car is moved up and down, a change in the stop position of the car, a change in lighting on / off control in the car, and an on / off control in the air conditioning fan in the car. This is information regarding changes, changes in the volume of speakers provided in the car, and the like.

  For example, when a request for remote response is notified from the monitoring terminal 6, the engineer terminal 4 notifies the fact, information on the elevator 2 that is the output source (for example, the elevator identification number), and the content of the abnormal signal (for example, abnormal) Are displayed on the first display unit 40. The engineer terminal 4 outputs the specification information regarding the changed specifications to the server 3 when the specification information regarding the changed specifications is input from the engineer who has confirmed these displays via the first input unit 41.

  The server 3 has a second storage unit 30 that stores data related to the specification information and can temporarily store specification information related to the changed specifications input from the engineer terminal 4.

  The second storage unit 30 stores specification information predicted to be input in association with data that can be rewritten by the first storage unit 200 of the control microcomputer 20. Specifically, the second storage unit 30 stores the specification information “change of the rated speed” in association with the address storing the rated speed in the first storage unit 200. The second storage unit 30 also includes, for example, the input specification information, the first data before rewriting in the first storage unit 200, and the second data rewritten corresponding to the specification information in the first storage unit 200. I remember it temporarily. In the remote monitoring system 1 of the present embodiment, the second storage unit 30 also stores a trial run procedure after data rewriting, which will be described later.

  When the specification information related to the changed specification is input (for example, input from the engineer terminal 4), the server 3 determines whether the car 21 is unmanned based on the information obtained from the elevator 2, When it is determined that there is no person, the first data stored in the first storage unit 200 of the control microcomputer 20 is rewritten to the second data corresponding to the specification information.

  Specifically, when the specification information related to the changed specification is input from the technician terminal 4 by the operation of the technician, the server 3 stores the specification information in the second storage unit 30 and the remote monitoring unit 5 "When receiving an event code indicating the opening / closing information of the car door and an event code indicating a button operation in the car from the control microcomputer 20, a signal (hereinafter referred to as a request to input to the server 3) to that effect is received. "Input request signal") is output. Also, the server 3 has not received the output of the event code indicating the button operation in the car for a predetermined time (for example, 3 minutes) after the output of the requested signal and the car door is in the closed state. In the case of the elevator 2, it is determined that “the car 21 is unmanned (is in an empty car stop state)”. Further, when the server 3 determines that “the car 21 is unmanned (in an empty car stopped state)”, the specification information stored in the second storage unit 30 (related to the changed specification input from the technician terminal 4). On the basis of the specification information), the first data stored in the first storage unit 200 of the control microcomputer 20 is rewritten with the second data corresponding to the specification information. At the time of this rewriting, the server 3 stores the first data before rewriting and the second data after rewriting in the second storage unit 30.

  On the other hand, when the car door is opened within a predetermined time (for example, 3 minutes) after the input request signal is output to the remote monitoring unit 5, the car door is again closed. Then, it waits until a predetermined time (for example, 3 minutes) elapses without receiving the output of the event code indicating the button operation in the car. At this time, the server 3 does not output the event code indicating the button operation in the car after the car door is closed again, and when the predetermined time (for example, 3 minutes) elapses, the server 3 Rewrite one data to second data.

  Further, when the server 3 receives an output of an event code indicating a button operation in the car within a predetermined time (for example, 3 minutes) after outputting the input request signal to the remote monitoring unit 5, From the time when an event code indicating the button operation in the car is received) for a predetermined time (in a state where the car door is in the door-closed state and the event code indicating the button operation in the car is not received). For example, wait until 3 minutes). If the predetermined time elapses in this state, the server 3 rewrites the first data to the second data.

  In addition, when a long time (for example, 30 minutes) elapses after the input request signal is output to the remote monitoring unit 5, the server 3 changes the specification to the technician terminal 4 because the car is manned. A message indicating that it cannot be performed (for example, a message such as “There is a user in the car, the specification change has been canceled. Please input the specification information again after a while.”) Is output.

  In the remote monitoring system 1 of the present embodiment, the server 3 causes the trial operation of the elevator 2 to be executed after the data rewriting of the control microcomputer 20 in addition to the above-described rewriting of data in the control microcomputer 20. Further, when the server 3 confirms an abnormality in the test operation after data rewriting of the control microcomputer 20, the server 3 returns the data of the control microcomputer 20 to the original data. Note that this test operation is, for example, a reciprocal operation for the first floor toward the intermediate floor, and the procedure of this test operation is stored in the second storage unit 30 as described above.

  For example, after the server 3 rewrites the second data in the first storage unit 200 and determines that the car is unattended based on the information obtained from the elevator 2, the operation based on the rewritten second data Is executed by the control microcomputer 20. When the server 3 confirms an abnormality in the operation, the server 3 rewrites the changed second data stored in the first storage unit 200 with the first data before the change. Note that the server 3 resets the power immediately before performing the operation based on the rewritten second data when the specification change is not reflected unless the power of the elevator 2 is reset.

  Specifically, the server 3 was rewritten after rewriting to the second data in the first storage unit 200 of the control microcomputer 20 and when the car was determined to be unattended based on information obtained from the elevator 2. When the control microcomputer 20 executes an operation based on the second data and an event code indicating an abnormality is output from the control microcomputer 20 to the remote monitoring unit 5 in this operation, this is output to the technician terminal 4. A request signal is output. Thereafter, if an event code indicating an abnormality is output from the control microcomputer 20 in this operation, the server 3 in the first storage unit 200 based on the first data and the second data stored in the second storage unit 30. Rewrite the second data after the change to the first data before the change.

  In the remote monitoring system 1 of the present embodiment, the server 3 further performs a trial run when the data of the control microcomputer 20 is returned to the original data after confirming the abnormality in the trial run after the data rewriting of the control microcomputer 20. When the server 3 confirms an abnormality in the further test operation, the server 3 notifies the engineer terminal 4 to that effect.

  For example, the server 3 determines that the car is unmanned after rewriting the second data after change stored in the first storage unit 200 to the first data before change and based on information obtained from the elevator 2. Then, the control microcomputer 20 is caused to execute the operation based on the rewritten first data before the change. When the server 3 confirms an abnormality in this operation (operation based on the rewritten first data before the change), the server 3 notifies the technician terminal 4.

  Specifically, the server 3 rewrites the changed second data stored in the first storage unit 200 to the first data before the change for a predetermined time (for example, 3 minutes), and the car door is in a door-closed state. If there is an event code indicating the button operation in the car, the elevator 2 determines that the car 21 is unmanned (is in an empty car stop state), and the control microcomputer 20 is operated. Is executed. In addition, if an event code indicating an abnormality is output from the control microcomputer 20 during this operation, the server 3 causes the technician terminal 4 to “return the elevator before the specification change because an abnormality was confirmed in the operation after the specification change. However, the abnormality was not improved. "

  In the remote monitoring system 1 of the present embodiment, when the server 3 rewrites the data of the control microcomputer 20 for a predetermined specification change such as a change in rated speed or an automatic inspection specification, the above-described trial operation (hereinafter referred to as “normal test operation”). In addition, a test run different from the normal test run is performed. For example, when the server 3 rewrites the data of the control microcomputer 20 with respect to the change of the rated speed, the automatic inspection specification, etc., the server 3 causes the control microcomputer 20 to execute an operation based on the rewritten second data, and an abnormality is detected in this operation. If not confirmed, the control microcomputer 20 is further caused to perform a trial operation different from the normal operation, and an abnormality is confirmed in this operation. Even in this case, if an abnormality is confirmed in this test operation (unusual test operation), the server 3 uses the first storage unit 200 based on the first data and the second data stored in the second storage unit 30. Rewrite the second data after the change to the first data before the change. In addition, when the server 3 determines that the car is unmanned, the control microcomputer 20 performs an operation based on the rewritten first data before the change (a normal test operation and a test operation different from the normal), and this operation ( When an abnormality is confirmed in either a normal test run or a test run different from normal), the engineer terminal 4 is notified.

  Specifically, if the specification change is a change in the rated speed, the server 3 performs a reciprocating operation from the top floor to the bottom floor as a test operation different from the normal test operation. Moreover, if the specification change is a change of the automatic inspection specification, the server 3 performs the automatic inspection operation as a trial operation different from the normal test operation. The automatic inspection operation is a preset operation that is automatically executed when the elevator 2 is maintained and inspected (for example, an operation assuming that a car call is made on each floor).

  In the remote monitoring system 1 described above, the technician can use the information obtained from the elevator 2 (for example, the event code output from the control microcomputer 20) from the place where the technician terminal 4 is present (for example, the technician terminal 4 is from the elevator 2). It can be accurately determined that the car is unattended when remotely located). Moreover, in the remote monitoring system 1, since the data regarding the specification memorize | stored in the 1st memory | storage part 200 of the control microcomputer 20 can be rewritten corresponding to the specification information input from the engineer terminal 4, for example, ( The specification of the control microcomputer 20 can be changed (from a location away from the elevator 2). Further, when the server 3 determines that the car is unattended (there is no user in the car), the data related to the specification stored in the first storage unit 200 of the control microcomputer 20 is associated with the specification information. Since it can be rewritten, even if an abnormality occurs in the elevator 2 by changing the data regarding the specifications, the influence on the user can be suppressed. Thus, according to the remote monitoring system 1, the specification of the elevator 2 can be changed remotely while suppressing the influence on the user.

  In the remote monitoring system 1 of the present embodiment, if an abnormality occurs in the operation of the elevator 2 by rewriting the first data related to the specification stored in the first storage unit 200 of the control microcomputer 20 to the second data, the second By returning the data to the first data, the operation of the elevator 2 can be restored.

  Further, in the remote monitoring system 1 of the present embodiment, even when the first data related to the specifications stored in the first storage unit 200 of the control microcomputer 20 is rewritten to the second data and then returned to the first data, the elevator If an abnormality occurs in the operation of No. 2, this fact can be confirmed by the technician terminal 4. For example, this abnormality can be confirmed remotely (from a place away from the elevator 2).

  Furthermore, in the remote monitoring system 1 of the present embodiment, the first floor for the intermediate floor is used as the operation after rewriting the first data regarding the specifications stored in the first storage unit 200 of the control microcomputer 20 to the second data. In order to perform a round-trip operation, the reciprocation from the top floor to the bottom floor will occur even if an overrun occurs (the car moves to a position beyond the assumed stop position of the car) due to specification changes. Compared to the case of driving, it is possible to suppress the push-up in which the car 21 passes through the top floor and collides, the push-down in which the car 21 passes through the bottom floor and collides, and the like.

  The remote monitoring system of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention. For example, the configuration of another embodiment can be added to the configuration of a certain embodiment, and a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of an embodiment can be deleted.

  For example, the specification information related to the changed specification is input to the server 3 by the engineer terminal 4, but the specification information is input by another terminal such as the customer terminal (terminal owned by the user) or the monitoring terminal 6. May be. In addition, when these terminals can be connected to the server 3 via a telephone line, specification information may be input by calling. In this case, the input of specification information by these terminals may be performed, for example, by inputting voice information for automatic voice guidance.

  The server 3 determines whether or not the car is unmanned when the car button is not operated in a state where the car door is closed for a predetermined time, but the camera provided in the car (for example, It may be determined whether or not the car is unmanned by analyzing the captured image of the monitoring camera. For example, when a human sensor is provided in the monitoring camera, the server 3 may determine whether or not the car is unattended based on the output of the human sensor.

  Further, the control microcomputer 20 may perform a part of the above-described series of processing performed by the server 3 instead of the server 3. For example, the control microcomputer 20 determines whether the car is unmanned, performs rewriting from the first data to the second data in the first storage unit 200 based on the specification information, a test run after the data rewriting, etc. However, the specification change input from the engineer terminal 4 is output to the control microcomputer 20 or the notification to the engineer terminal 4 (the abnormality is confirmed in the operation based on the second data after the change, and the rewritten change before the change is made. Notification that the abnormality has been confirmed in the driving based on the first data may also be performed. Further, instead of the server 3, another terminal such as the monitoring terminal 6 can determine whether the car is unmanned or rewrite the first data to the second data in the first storage unit 200 based on the specification information. A series of processing may be performed.

  The remote monitoring system 1 of the above embodiment includes a plurality of remote monitoring units 5, but may include a single remote monitoring unit 5. In this case, the remote monitoring system 1 may include one elevator.

  The communication system R1 may include the Internet instead of the telephone line. For example, as shown in FIG. 2, the communication system R1 can communicate with the server 3 sequentially from the elevator 2 via the remote monitoring unit 5 and the Internet, and conversely from the server 3, the Internet and the remote monitoring unit 5 It may be a communication system capable of communicating with the elevator 2 via In this case, the communication system between the communication system R1 and the server 3 and the technician terminal 4 is partially shared (Internet).

  Although the remote monitoring system 1 of the said embodiment was intended for the elevator as the lifting device, it may be intended for the escalator. In this case, the remote monitoring system 1 includes a PLC unit (Programmable Logic Controller) as an information output unit instead of the control microcomputer 20, and an event code is output in the same manner as the control microcomputer 20. In this case, the specification information is information related to the specifications of the escalator (for example, change in ascending / descending speed, direction of movement (up or down), etc.). Further, in this case, whether or not the escalator step is unmanned can be determined by, for example, the output of a surveillance camera that captures an image of the entire escalator or a human sensor provided in the surveillance camera. Even in the abnormal remote monitoring system 1, it is possible to change the specifications of the escalator while suppressing the influence on the user.
