Description

  The present invention relates to a remote monitoring system for remotely monitoring a lifting device such as an elevator or an escalator.

  2. Description of the Related Art Conventionally, a remote monitoring system that monitors an operation state of a lifting device has been provided. The remote monitoring system includes an elevating device including a control microcomputer for controlling the operation, and a monitoring terminal communicably connected to the control microcomputer of the elevating device for remotely monitoring the operation of the elevating device ( Patent Document 1).

  In such a remote monitoring system, when the control microcomputer determines that the operation status of the lifting device is abnormal, the monitoring terminal of the monitoring center stays at the monitoring center based on a signal from the lifting device (control microcomputer). The operating status of the elevating device (operation stop, etc.) is notified to the monitoring personnel who are present. Along with this, the observer requests a technician to be seconded to the site.

  The elevating device is normally operated automatically, but may be manually operated by a technician during maintenance. A technician may intentionally operate the elevating device during maintenance for the purpose of checking operation or the like so that the operation state of the elevating device becomes abnormal. However, since the control microcomputer can detect an abnormality of the lifting device even during maintenance, the control microcomputer detects intentional abnormal operation of the lifting device as an abnormality of the lifting device, and notifies the monitoring terminal that the lifting device is abnormal. May be issued.

  In order to avoid this unnecessary notification, the lifting device is provided with a maintenance switch capable of prohibiting the control microcomputer from generating a signal (signaling that the lifting device is abnormal). The maintenance switch is a mechanical switch. The ON operation prohibits the control microcomputer from issuing a signal to the effect that the elevating device is abnormal, and the OFF operation indicates that the elevating device is abnormal to the control microcomputer. Allow the signal to be issued.

  Even if a technician manually turns on the maintenance switch before starting the maintenance of the elevating device, even if the elevating device under maintenance intentionally causes an abnormality, the monitoring terminal notifies the monitoring personnel of the abnormality of the elevating device. Never announce. In addition, after the maintenance of the elevating device is completed, the technician manually turns off the maintenance switch, and when an abnormality occurs in the elevating device that normally operates, the monitoring terminal notifies the monitoring person of the abnormality of the elevating device. .

  However, as described above, the maintenance switch is a mechanical switch that requires a manual operation at the time of an ON operation or an OFF operation, and thus a technician may forget such an operation. If the technician forgets to turn off the maintenance switch after the maintenance is completed, the control microcomputer does not issue a signal indicating that the elevator is abnormal when an abnormality actually occurs in the elevator during normal operation. The monitoring terminal does not notify the monitoring personnel of the abnormality of the elevating device.

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

  Hereinafter, a remote monitoring system for a lifting device according to the present invention will be described. The remote monitoring system is a system that remotely monitors the operation status of the lifting device. In this remote monitoring system, the elevating device in the normal state outputs an abnormal signal when an abnormality such as a trouble such as operation stop occurs, and based on the abnormal signal, the monitoring terminal connected to the elevating device raises and lowers. Provides notification of device abnormalities. By performing such notification, a monitoring person who is monitoring the monitoring terminal can dispatch a technician to the site (an elevating device having an abnormality).

  On the other hand, the technician can switch the output of the abnormal signal from the control microcomputer by operating the maintenance work switch provided on the lifting / lowering device. Output is prohibited. In the remote monitoring system for the lifting device according to the present invention, the technician terminal is notified when the lifting device in the maintenance state performs the normal operation a predetermined number of times. If necessary, the control microcomputer can be switched from the maintenance state to the normal state by operating the maintenance work switch, so that the control microcomputer can output an abnormal signal.

  The elevator device includes an elevator, an escalator, and the like. Hereinafter, a remote monitoring system for the elevator will be described.

  As shown in FIG. 1, the remote monitoring system includes an elevator 2 having a control microcomputer 20 that can be switched between a normal state in which an abnormal signal can be output and a maintenance state in which the output of the abnormal signal is prohibited. A monitoring terminal (terminal) 3 connected via R1 and a technician terminal (technical mobile terminal) 4 connectable to the monitoring terminal 3 are provided.

  The remote monitoring system 1 of the present embodiment includes a remote monitoring unit 5 provided in a communication system R1 (between the control microcomputer 20 and the monitoring terminal 3). The communication system R1 can communicate with the monitoring terminal 3 via the remote monitoring unit 5 and the telephone line in order from the control microcomputer 20, for example, and can communicate with the monitoring terminal 3 via the telephone line and the remote monitoring unit 5 in reverse. Communication system capable of communicating with the elevator 2.

  Although one monitoring terminal 3 is shown in FIG. 1, the remote monitoring system 1 of the present embodiment includes a plurality of monitoring terminals 3. In addition, since each of the monitoring terminals 3 is connected to the elevator 2 via the communication system R1, the remote monitoring system 1 of the present embodiment includes a plurality of elevators. Further, FIG. 1 shows two engineer terminals 4A and 4B, but the remote monitoring system 1 of the present embodiment includes three or more engineer terminals 4.

  The elevator 2 has, in addition to the control microcomputer 20, a car 21 connected to the control microcomputer 20 and moving up and down in the hoistway.

  When a trouble or the like occurs in the elevator 2, maintenance work may be performed on the elevator 2 by a technician. In the elevator 2 during the maintenance work, for example, the manual operation and the normal operation may be repeated. The maintenance work of the elevator 2 is performed after a lapse of a predetermined time (for example, about 2 to 3 hours) after the elevator 2 is set to the normal operation after the technician or the like confirms that the trouble is resolved, or the normal operation of the elevator 2 Is repeated a predetermined number of times (for example, about 5 to 10 times) to complete the process. One normal operation is an operation from the start of the movement of the car 21 in the normal state to the stop of the movement of the car 21. In addition, it is not assumed that the user gets on during the maintenance work. Specifically, the elevator 2 during the maintenance work does not accept a call from the landing button.

  The car 21 is connected to the control microcomputer 20 and has a maintenance switch (maintenance work switch) 210 for switching the control microcomputer 20 between a normal state and a maintenance state.

  The maintenance switch 210 is a mechanical switch that can be operated by a technician or the like. In the remote monitoring system 1 of the present embodiment, when the maintenance switch 210 is ON, the control microcomputer 20 can output an abnormal signal because it is in a normal state. When the maintenance switch 210 is turned off, the control microcomputer 20 is in the maintenance state, so that the output of the abnormal signal is prohibited. The operation of switching the maintenance switch 210 from ON to OFF is referred to as an OFF operation, and the operation of switching the maintenance switch 210 from OFF to ON is referred to as an ON operation.

  Further, in the remote monitoring system 1 of the present embodiment, the control microcomputer 20 can output a signal indicating the normal state and a signal indicating the maintenance state. Specifically, the maintenance switch 210 outputs a signal to that effect to the control microcomputer 20 when the state of the switch itself is switched (when an ON operation or an OFF operation is performed). And to the monitoring terminal 3 via the communication system R1.

  The car 21 is provided with various sensors capable of detecting the operation status of the elevator 2 and outputting the detection result as a signal relating to the operation status of the elevator 2. The sensor can output various signals corresponding to the operation status of the elevator 2.

  In the remote monitoring system 1 of the present embodiment, for example, an UP button and a DOWN button are provided outside the car 21 (for example, outside the ceiling of the car 21). By pressing these buttons when the maintenance switch 210 is ON, the car 21 can be moved up and down at a lower speed than the normal operation. Therefore, such manual operation is performed, for example, during maintenance work by a technician. Will be

  The control microcomputer 20 always receives output of information on the operation status of the elevator 2 by a sensor (a sensor provided in the car 21). The control microcomputer 20 can switch between the normal state and the maintenance state (between the normal state and the maintenance state) by switching the maintenance switch 210 (when the maintenance switch 210 is turned on or off).

  When the information is output from the sensor, the control microcomputer 20 uses the output information to determine, for example, car position information, car door opening / closing information, car driving motor driving information, and power failure. Can be output. Specifically, when information is output from the sensor, the control microcomputer 20 outputs an event code based on the output information in a normal state, and outputs an event code based on the output information in a maintenance state. Store (accumulate) the event code. The event code includes an abnormal signal (an event code indicating an abnormality of the elevator 2 such as a lock of a user in the car 21, a failure of a car door or a landing door, or a service life of a car light).

  As described above, when the information regarding the abnormality of the elevator 2 is output from the sensor, the control microcomputer 20 outputs an abnormality signal to the monitoring terminal 3 via the communication system R1 in the normal state. Further, when the information regarding the abnormality of the elevator 2 is output from the sensor, the control microcomputer 20 stores (accumulates) the history of the abnormality signal when the elevator is in the maintenance state. In the remote monitoring system 1 of the present embodiment, when the control microcomputer 20 is switched to the maintenance state, the control microcomputer 20 counts the number of times the normal operation has been continuously performed from that point in time, and also stores the number of times.

  Specifically, the maintenance work of the elevator 2 is completed by repeating the normal operation of the elevator 2 in the normal operation state a predetermined number of times after the maintenance worker confirms that the trouble has been resolved. Note that the normal operation is an automatic operation in a state where no abnormality occurs in the elevator 2. One normal operation is an operation from the start of the movement of the car 21 in the elevator 2 set to the normal operation to the stop of the movement of the car 21. Further, "the normal operation is continuously repeated a predetermined number of times" means that only the normal operation is continuously performed a predetermined number of times or more, and does not correspond to a case where a manual operation is included during the normal operation.

  Specifically, "the normal operation is repeated a predetermined number of times continuously" means that, in the elevator 2 which is in the normal operation, the car 21 starts moving by pressing the call button at the landing, and then arrives at this landing. The normal operation until the car 21 moves to the destination floor and stops by pressing the destination button in the car 21 is continuously performed a predetermined number of times or more. Note that a period during which the movement of the car 21 is stopped may be included during one normal operation.

  The control microcomputer 20 of the present embodiment can be connected to the technician terminal 4 connected to the monitoring terminal 3 via the communication system R1. The control microcomputer 20 can switch from the maintenance state to the normal state based on an instruction signal output from the technician terminal 4 in addition to the operation of the maintenance switch 210 described above. Even if the control microcomputer 20 switches to the normal state based on the instruction signal from the technician terminal 4, the state of the maintenance switch 210 (for example, the state in which the maintenance switch 210 is ON) remains unchanged. In other words, even if the control microcomputer 20 switches to the normal state based on the instruction signal from the technician terminal 4, the maintenance switch 210 is not physically operated.

  When an abnormal signal is output from the control microcomputer 20, the remote monitoring unit 5 monitors information (for example, the machine number of the elevator 2) regarding these output sources and the contents of the abnormal signal (for example, an event code). Output to terminal 3.

  In the remote monitoring system 1 of the present embodiment, the remote monitoring unit 5 is in a normal state signal (for example, a signal indicating that the maintenance switch 210 has been turned OFF) or a maintenance state output from the control microcomputer 20. An output of a signal indicating that the maintenance switch 210 has been turned ON is received. When a signal indicating the normal state or a signal indicating the maintenance state is output from the control microcomputer 20, the remote monitoring unit 5 outputs the signal to the monitoring terminal 3 as it is.

  The monitoring terminal 3 of the present embodiment monitors, for example, a large number of elevators installed in a plurality of areas and is installed in a monitoring center or the like, which is a building separated from the target elevator. A monitoring member (operator) is resident in the monitoring center of the present embodiment.

  To the monitoring terminal 3, information (for example, the elevator number of the elevator 2) and an abnormal signal are output from the control microcomputer 20 via the communication system R1 regarding the output source elevator. The monitoring terminal 3 includes, for example, a display unit 30 capable of displaying information (for example, an elevator number) of the output source elevator 2 and contents of an abnormal signal (for example, an event code) from the control microcomputer 20. The display unit 30 is, for example, a display.

  When the control microcomputer 20 outputs the information of the output source elevator 2 (for example, the elevator number) and the abnormality signal, the monitoring unit 3 displays the information of the output source elevator 2 (for example, the elevator number) on the display unit 30. And, by displaying the content of the abnormal signal (for example, an event code or the like), an abnormal condition relating to the elevator 2 is notified to a supervisor. The observer can confirm the abnormality of the elevator 2 by checking the display, and can request a technician to be dispatched as necessary.

  In addition, the monitoring terminal 3 always outputs a signal indicating the normal state or the maintenance state output from the control microcomputer 20 (for example, the maintenance switch 210 output from the maintenance switch 210 via the control microcomputer 20 and the communication system R1). The control microcomputer 20 recognizes whether the control microcomputer 20 is in the normal state or the maintenance state by receiving the signal indicating that the state has been switched. When the monitoring terminal 3 determines that the elevator 2 has performed the normal operation a predetermined number of times when the control microcomputer 20 recognizes that the maintenance is in the maintenance state, the monitoring terminal 3 notifies the technician terminal 4 (for example, it is possible to forget to turn off the maintenance switch 210). Notification that there is a possibility).

  Specifically, when the monitoring terminal 3 recognizes that the control microcomputer 20 is in the maintenance state, the monitoring terminal 3 acquires from the control microcomputer 20 the number of times the normal operation has been continuously performed from the point in time when the control microcomputer 20 is switched to the maintenance state. If the number is less than the predetermined number, the engineer terminal 4 is not notified. If the number is more than the predetermined number, the history of the abnormal signal stored in the control microcomputer 20 is acquired from the control microcomputer 20. The predetermined number of times is, for example, 5 to 10 times.

  In the remote monitoring system 1 of the present embodiment, in addition to the display unit 30, the monitoring terminal 3 displays information on a plurality of notification destinations (for example, the mail address of the technician terminal 4) with information on the technician (for example, the name of the technician) And a storage unit 31 that stores the information in association with the information.

  In addition, in the remote monitoring system 1 of the present embodiment, each time the monitoring terminal 3 requests a secondment to a technician, the storage unit 31 stores information on a request for a secondment to the technician by the monitoring terminal 3 (information on the elevator 2 to which the second person is dispatched). (For example, an elevator number) and information (for example, the name of the technician) relating to the technician who has requested the secondment. If a request is made to dispatch a plurality of technicians for one elevator, information on the elevator 2 at one destination (for example, one elevator number) is provided with information on a plurality of technicians who have requested a dispatch. (Eg, the names of a plurality of technicians) are stored in association with each other. Further, when further requesting a secondment for an elevator which has requested a secondment, the storage unit 31 updates and stores information on a secondment request for the elevator (the latest information on a second request to a technician is stored). Remember).

  In the remote monitoring system 1 of the present embodiment, when information (for example, an elevator number) of the output source elevator 2 and an abnormal signal are output from the control microcomputer 20, the monitoring terminal 3 first outputs the output source elevator 2. Is compared with the information on the elevator stored in the storage unit 31, and the information on the elevator 2 that matches the information is extracted. Further, the monitoring terminal 3 extracts, from the storage unit 31, information about the technician associated with the matched elevator information (for example, the name of the technician who has requested a secondment), and information about the extracted technician (for example, the It is possible to extract the information of the notification destination corresponding to (name) (for example, the mail address of the technician terminal 4).

  In the remote monitoring system 1 of the present embodiment, the monitoring terminal 3 recognizes that the control microcomputer 20 is in the maintenance state, and determines the number of times that the normal operation has been continuously performed from the time when the control microcomputer 20 is switched to the maintenance state. When it is confirmed that the number of times is equal to or more than that and the abnormality signal is not accumulated in the control microcomputer 20 (in a state where the elevator 2 is recognized as being in the maintenance state, the elevator 2 performs the normal operation continuously for a predetermined number of times. And, when no abnormality occurs in the elevator 2), as described above, the information of the notification destination is extracted from the storage unit 31, and the notification destination (for example, the technician terminal 4) is notified (for example, of the elevator 2). A notification indicating that the OFF operation of the maintenance switch 210 may be forgotten is performed. This notification is, specifically, a notification such as “normal operation was performed five times consecutively with the maintenance switch on for the elevator of elevator number 001”.

  If a plurality of notification destinations (for example, both the engineer terminals 4A and 4B) are extracted, the monitoring terminal 3 notifies the plurality of notification destinations (for example, both the engineer terminals 4A and 4B). I do.

  Further, in the remote monitoring system 1 of the present embodiment, when the monitoring terminal 3 gives a notification to the effect that the OFF operation of the maintenance switch 210 of the elevator 2 may be forgotten, the monitoring terminal 3 sends a message to a technician who checks the notification. If necessary, the control microcomputer 20 can be notified to switch from the maintenance state to the normal state.

  The technician terminal 4 can be connected to the monitoring terminal 3 via the Internet. The technician terminal 4 is, for example, a terminal such as a smartphone, a PDA, and a notebook computer. Further, for example, upon receiving a request for dispatch, the technician terminal 4 is carried by a technician who is dispatched to an elevator to deal with an elevator trouble. The technician terminal 4 has, as an information output unit, a display unit 40 that displays information output from the monitoring terminal 3 (a request or notification of a secondment from the monitoring terminal 3).

  The technician possessing the technician terminal 4 can be dispatched to the site (for example, the elevator 2) by confirming the request for dispatch displayed on the display unit 40. In addition, the technician possessing the technician terminal 4 may check the contents of the notification displayed on the display unit 40 to check the status of the elevator 2 (for example, the operator may have forgotten to turn off the maintenance switch 210 of the elevator 2). That there is).

  In the remote monitoring system 1 according to the present embodiment, the technician terminal 4 has an input unit 41 capable of inputting information by an operation of a technician in addition to the display unit 40. The input unit 41 is, for example, an input key or a keyboard. When the technician terminal 4 includes a touch panel display, this display also serves as the display unit 40 and the input unit 41.

  Further, in the remote monitoring system 1 of the present embodiment, the display unit 40 of the technician terminal 4 notifies the operator that there is a possibility that the operator has forgotten to turn off the maintenance switch 210 of the elevator 2 (for example, “the elevator number 001 The normal operation was performed five times in a row while the maintenance switch was ON for the elevator. ") And the control microcomputer 20 is urged to switch from the maintenance state to the normal state as necessary. A notification (such as "When the maintenance switch is turned off, input OFF from the input key") can be displayed. The technician confirms such a notification and operates the input unit 41 to output an instruction signal via the Internet, the monitoring terminal 3 and the communication system R1, and switch the control microcomputer 20 to the normal state. it can.

  According to the remote monitoring system 1 described above, the technician terminal 4 is notified that the normal operation of the elevator 2 has been performed a predetermined number of times continuously in the maintenance state. In this state, it is possible to grasp the situation in which the elevator 2 is normally operated continuously for a predetermined number of times (for example, five times), and switch the control microcomputer 20 from the maintenance state to the normal state according to the judgment of a technician himself.

  According to the remote monitoring system 1 of the present embodiment, the technician can switch the elevator 2 from the maintenance state to the normal state in which an abnormal signal can be output as necessary, so that the technician notifies the elevator 2 of the abnormality. When it is determined that it should be performed, the abnormality of the elevator 2 can be accurately notified.

  Further, according to the remote monitoring system 1 of the present embodiment, the monitoring terminal 3 recognizes that the control microcomputer 20 is in the maintenance state, and determines that the number of times the normal operation has been performed from the point of switching to the maintenance state is the predetermined number of times. In the above case, the maintenance work is completed after confirming that the abnormality signal is not accumulated in the control microcomputer 20 (the sensor does not detect the abnormality of the elevator 2) and notifying the engineer terminal 4. If it is highly probable, a notification can be made.

  Furthermore, according to the remote monitoring system 1 of the present embodiment, it is highly likely that the technician who has been dispatched to the output source elevator 2 (the maintenance staff 210 has a high possibility of forgetting to turn off the maintenance switch 210 and that the elevator 2 is under maintenance work) Is notified from the monitoring terminal 3 to the engineer who has a high possibility of grasping the situation, it is possible to more accurately determine whether to switch the control microcomputer 20 to the normal state.

  It should be noted that the remote monitoring system 1 of the present invention is not limited to the above embodiment, and it is needless to say that various changes can be made without departing from the scope of the present invention. For example, the configuration of another embodiment can be added to the configuration of one embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Further, a part of the configuration of an embodiment can be deleted.

  For example, the monitoring terminal 3 recognizes that the control microcomputer 20 is in the maintenance state, and when the number of times the normal operation is continuously performed from the time when the control microcomputer 20 is switched to the maintenance state is equal to or more than the predetermined number, After confirming that no abnormal signal is accumulated (the sensor does not detect an abnormality of the elevator 2), the technician terminal 4 is notified, but the notification is performed without confirming the accumulation of the abnormal signal. May go. Even in this case, the monitoring terminal 3 recognizes that the control microcomputer 20 is in the maintenance state, and determines that the number of times the normal operation has been continuously performed since the switching to the maintenance state is equal to or more than the predetermined number. Technician who has the technician terminal 4 grasps the contents of the notification (a situation that the elevator 2 is normally operated a predetermined number of times (for example, 5 times continuously) in the maintenance state), and if necessary. Thus, the control microcomputer 20 can be switched from the maintenance state to the normal state.

  The monitoring terminal 3 stores information on a request for a secondment to a technician, and extracts information on a notification destination based on this information. However, the monitoring terminal 3 may not store information on a request for a secondment to a technician. For example, the storage unit 31 of the monitoring terminal 3 may store information about the notification destination (for example, the mail address of the technician terminal 4) in association with information about the elevator 2 (for example, elevator number). In this case, the monitoring terminal 3 stores information on the elevator 2 (for example, elevator number) output from the control microcomputer 20 and information on the elevator 2 (for example, elevator number) stored in the storage unit 31. By comparison, it is possible to extract information (for example, the e-mail address of the technician terminal 4) related to the notification destination associated with the information (for example, the elevator number) about the matched elevator 2.

  The monitoring terminal 3 may include a display unit, and a configuration (for example, a data server) different from the monitoring terminal 3 may include a storage unit that stores information of a notification destination in association with information of the elevator 2. Even in this case, the monitoring terminal 3 can extract the notification destination from the information stored in the storage unit and notify the extracted notification destination.

  In the remote monitoring system 1 of the above embodiment, the terminal is the monitoring terminal 3, but may have a different configuration (for example, a server) from the monitoring terminal 3.

  The technician terminal 4 may not be able to output an instruction signal to the control microcomputer 20. In this case, the technician terminal 4 may not have the input unit 41. In this case, the technician having the technician terminal 4 to which the notification has been sent outputs an instruction signal to the monitoring terminal 3 to switch the control microcomputer 20 from the maintenance state to the normal state by e-mail or the like. The display unit 30 displays a message such as "There is a request to switch the control microcomputer 20 from the maintenance state to the normal state" based on the instruction signal, and the observer who confirms the display normally switches the control microcomputer 20 through the monitoring terminal 3. The state may be switched.

  The technician terminal 4 may be connected to the monitoring terminal 3 via a telephone line instead of the Internet. In this case, instead of the display unit 40, the technician terminal 4 may include a speaker that outputs a notification from the monitoring terminal 3 as a voice message, and a microphone that can input an instruction signal by voice information as the input unit 41. . Even in this case, the technician can confirm the content of the notification by a voice message flowing from the speaker of the technician terminal 4. In addition, the technician can input an instruction signal from the microphone as needed, and switch the control microcomputer 20 to the normal state.

  The maintenance switch 210 was not physically operated even if the control microcomputer 20 was switched to the normal state based on the instruction signal from the engineer terminal 4, but the control microcomputer 20 was in the normal state based on the instruction signal from the engineer terminal 4. May be physically operated (for example, an OFF operation) when switching to.

  The communication system R1 includes a telephone line, but may include the Internet instead of the telephone line as shown in FIG. Further, the communication system R1 may not include the remote monitoring unit 5.

  Although the remote monitoring system 1 according to the above embodiment includes a plurality of elevators, the remote monitoring system 1 may include a single elevator. Further, the remote monitoring system 1 according to the above-described embodiment includes a plurality of monitoring terminals 3, but may include a single monitoring terminal 3.

  Furthermore, although the remote monitoring system 1 of the above-described embodiment includes the plurality of technician terminals 4, the remote monitoring system 1 may include one technician terminal 4. In this case, the monitoring terminal 3 only needs to store the information of the technician terminal 4 as the notification destination, and may always notify the technician terminal 4.

  Although the remote monitoring system 1 according to the above embodiment targets an elevator, the remote monitoring system 1 may target an escalator. In a remote monitoring system for an escalator, the event code includes an abnormal signal (an event code indicating an abnormality such as pinching of a foreign object or deviation of a handrail). In the escalator, the maintenance switch may be provided on the control panel. Note that, in the escalator, the normal operation is repeated a predetermined number of times continuously ”means that the handrail or step circulates (for example, after the handrail or step starts moving by operating the escalator, the circuit goes around once and returns to the original position. Is repeated continuously a predetermined number of times.
