Description

  Embodiments described herein relate generally to an elevator remote diagnosis operation method, an elevator control device, and an elevator remote diagnosis operation program.

  Remote diagnosis driving is known in which an elevator automatically diagnoses whether there is an abnormality. In the remote diagnosis operation, a remote automatic diagnosis operation signal is transmitted from the remote monitoring center to the property where the elevator is installed via the communication network. On the elevator side, when a remote automatic diagnosis operation signal is received, a diagnosis program having a preset schedule in the elevator control device is activated to perform automatic operation of the elevator.

  When there are a plurality of elevator units and the group management control is performed, conventionally, the unit to be diagnosed is separated from the group management for diagnosis operation. This is to prevent a call from being generated during a remote diagnosis operation and a call being assigned to the unit being diagnosed to interrupt the diagnosis operation.

Check. In the door opening / closing diagnosis, it is confirmed that data such as door opening / closing time, opening / closing speed and torque are normal.

<Diagnosis operation processing under group management control>
FIG. 3 is a flowchart showing a diagnostic operation process under group management control.

  As shown in FIG. 3, in the elevator diagnostic operation method according to the embodiment, when the diagnosis cycle arrives in order to execute the first to fourth diagnosis items described above, the master side group management control unit of the elevator control device 30A. 32A checks whether or not there is a machine that can perform diagnostic operation (ST1).

  When there are a plurality of units that are not assigned a call and can be diagnosed, diagnosis of the first unit set in advance is started (ST2). Specific diagnosis operation processing will be described later with reference to the flowchart of FIG.

  When the diagnosis operation of the first car is completed (ST3 YES), the diagnosis result is stored in the diagnosis result storage unit 35 (ST4).

  Next, the diagnosis of the next unit to which no call is assigned is started, and when the diagnosis operation is completed, the diagnosis result is stored in the diagnosis result storage unit 35 (ST5, ST6, ST7).

  When all the diagnosis of the unit capable of performing the diagnostic operation is completed, the diagnosis result stored in the diagnosis result storage unit 35 is transmitted to the monitoring center 10 via the communication control unit 31 and the remote monitoring device 20 (ST8, ST9).

  Next, a specific diagnostic operation procedure will be described with reference to the flowchart of FIG.

  When the diagnostic cycle arrives and a diagnostic command is input, the diagnostic program operates and the flowchart shown in FIG. 4 is started.

  When a diagnostic command from the remote monitoring device 20 (20A, 20B) is transmitted to the elevator control device 30 (30A, 30B) according to the remote diagnosis operation schedule registered in the schedule registration unit 11 of the monitoring center 10, the operation control unit At 33, it is determined whether or not the remote diagnosis operation is “practicable”. Here, the “state in which the remote diagnosis operation can be performed” refers to a state in which there is no car call of the elevator 2 and 10 seconds have elapsed since the diagnosis command was output. In the “practicable state”, the car illumination is turned off, and the door open button light and the power failure light are turned on (automatic diagnosis operation start condition).

  When the automatic diagnosis operation start condition is satisfied, the operation control unit 33 confirms the current car position (ST12). Next, based on the current car position, it is determined which of the top floor TF and the bottom floor BF is closer to the floor (ST13).

  When the car position is close to the top floor TF, traveling to the top floor TF is executed. When the current car position is close to the lowermost floor BF, traveling to the lowermost floor BF is executed. At this time, the operation control unit 33 determines whether to execute “in-hoistway limit switch diagnosis” or “brake diagnosis”. When traveling to the top floor TF (ST13 YES), travel to the top floor TF (ST14) while performing the diagnosis item “limit switch diagnosis in hoistway”, and the top floor limit switch 4LS installed at the end of the top floor TF. Is diagnosed (ST15). At this time, the result of “in-hoistway limit switch diagnosis” is stored in the diagnosis result storage unit 35. Thereafter, “brake diagnosis” is executed at the top floor TF (ST16). In the “brake diagnosis”, it is confirmed that the brake holding force is normal by applying torque to the hoisting machine 8 while the car 4 is stopped without releasing the brake Br. When the “brake diagnosis” is completed, the car 4 is driven to the lowest floor BF (ST17). At this time, during traveling to the lowest floor BF, diagnosis is performed for an undiagnosed limit switch among limit switches whose results are not stored in the diagnosis result storage unit 35, that is, limit switches in the hoistway (ST18). .

  In addition, even when a call by the user is generated during the “limit switch diagnosis in hoistway” and the remote diagnosis operation is interrupted, the hoistway is based on the data stored in the diagnosis result storage unit 35. Since the inner limit switch diagnosis operation can be continuously performed, the remote diagnosis can be continued even during the call answering. As shown in FIG. 5, for example, when there are n limit switches in the hoistway, the result of the hoistway limit switch diagnosis stored in the diagnosis result storage unit 35 is when driving to the top floor TF. For the limit switch that has been diagnosed and completed the diagnosis of the limit switch in the hoistway, it is stored in a format that can be used to determine whether it has been implemented or whether the result is good or bad. Further, the result of the limit switch that has been confirmed at the time of call response even when a call is made by the user during operation to the top floor TF is stored in the diagnosis result storage unit 35.

  When the car 4 arrives at the lowermost floor BF, the lowermost floor limit switch 3LS installed at the end of the lowermost floor BF is diagnosed (ST19). Thereafter, the rated speed diagnosis is executed from the lowest floor BF to the uppermost floor TF (ST20), and the car 4 is stopped at each floor, stopped at each floor, and “door open / close diagnosis” is executed (ST21). ). At this time, in consideration of security or the like, if there is a floor that is set to be unusable by the user by the elevator control device 30 (30A, 30B), the door opening / closing diagnosis is not executed. In addition, since the “door open / close diagnosis” is performed at each floor to open and close the door, there is a high possibility that the user will be interrupted by a car call. Therefore, in the “door opening / closing diagnosis”, the progress of the remote diagnosis is stored in the diagnosis result storage unit 35 in the floor where the “door opening / closing diagnosis” is performed or not performed, and continues even after the call response from the user. Thus, it is possible to restart from the floor where the “door opening / closing diagnosis” is not performed. Further, the door opening / closing at the time of call response is also stored in the diagnosis result storage unit 35 as the diagnosis result at the time of call response on the floor where the call is not performed. As shown in FIG. 6, for the result stored at the “door opening / closing diagnosis”, for example, when the number of floors is n, the result of the floor on which the diagnosis is completed is the presence / absence of the implementation or the quality of the result. Store in a format that understands.

  On the other hand, when the current car position is close to the lowermost floor BF, traveling to the lowermost floor BF is executed. At this time, the operation control unit 33 determines whether to execute “in-hoistway limit switch diagnosis” or “brake diagnosis”. When traveling to the top floor BF (ST13NO), travel to the bottom floor BF (ST22) while performing the diagnosis item “limit switch diagnosis in hoistway”, and the bottom floor installed at the end of the bottom floor BF The limit switch 3LS is diagnosed (ST23). At this time, the result of “in-hoistway limit switch diagnosis” is stored in the diagnosis result storage unit 35. Thereafter, the vehicle travels to the top floor TF (ST24). When traveling to the top floor TF, a rated speed diagnosis is performed (ST25), and a diagnosis is performed for an undiagnosed hoistway limit switch whose result is not stored in the diagnosis result storage unit 35 during traveling (ST25). ST26).

  In the top floor TF, diagnosis of the top floor limit switch 4LS is executed (ST27) and “brake diagnosis” is executed (ST28). When the “brake diagnosis” is completed, the car 4 is driven to the lowest floor BF, stopped on each floor, and door opening / closing diagnosis is executed (ST21). Of course, in step 22, the door opening / closing diagnosis may be executed by stopping each floor while traveling to the lowest floor.

  When the “door opening / closing diagnosis” is completed and all the remote diagnosis of the elevator is completed, the diagnosis result stored in the diagnosis result storage unit 35 is monitored from the communication control unit 31 via the remote monitoring device 20 (20A, 20B). 10 is sent.

<Diagnosis operation when a car call occurs>
Next, processing will be described when a car call is generated during diagnostic operation.

  During the diagnostic operation shown in FIG. 7, the operation control unit 33 of the elevator control device 30 (30A, 30B) monitors whether a car call is generated. As shown in the flowchart of FIG. 7, when a car call is generated during the diagnostic operation (ST31, ST32 YES), the call is assigned to the corresponding car (ST33). If the assigned unit is not in the diagnostic operation, it answers the call (ST34, ST35).

  If the assigned unit is in the diagnostic operation (ST34 YES), it is determined whether the diagnostic operation is completed within a predetermined time and a call response is possible (ST36). If the call cannot be answered within the predetermined time, the call is assigned to another unit (ST37). When one diagnostic item of the diagnostic operation is completed in about 30 seconds to 1 minute and a call response is possible, for example, the diagnostic operation is interrupted and a car call is answered (ST38, ST39). For example, if the door opening / closing diagnosis is in progress, when the door opening / closing diagnosis of the floor being diagnosed is completed, the door opening / closing diagnosis of the next floor is interrupted and the call is answered. When the diagnosis operation is interrupted, the interrupted floor and the diagnosis results up to that point are stored in the diagnosis result storage unit. When the call response ends, the diagnosis is resumed from the suspended floor (ST40, ST41).

  When all the diagnosis operations are completed, the diagnosis result is transmitted (ST42, ST43).

  In this way, when the diagnosis cycle arrives, while performing group management operation, while performing remote diagnosis operation one unit at a time in a predetermined order with respect to units that are not assigned a call, when a call occurs When the call can be answered within a predetermined time, the remote diagnosis is interrupted and the call is answered. In addition, when the target unit is unable to respond to the call response, a unit that can respond to the call is assigned. For this reason, efficient remote diagnosis operation is possible without impairing the service to the user.

  FIG. 8 shows processing during door opening / closing diagnosis.

  In the door opening / closing diagnosis, it stops at each floor and opens / closes the door to diagnose whether it is normal. Therefore, there is a possibility that a user at the landing will get into the car during the diagnostic driving in response to the landing call even though the diagnostic driving is in progress.

  Therefore, as shown in the flowchart of FIG. 8, when a call is generated during the door opening / closing diagnosis (ST51, ST52), the machine under the door opening / closing diagnosis does not stop at the call generation floor, and the next call is generated. It moves to the floor which is not, and the door opening / closing diagnosis of that floor is executed (ST53). When the door opening / closing diagnosis of all floors excluding the call generation floor is completed (ST54), the unit moves to the call generation floor and executes the door opening / closing diagnosis (ST55). When the door opening / closing diagnosis for all floors is completed (ST56), the diagnosis result is stored in the diagnosis result storage unit (ST57).

  In this way, the machine under the door opening / closing diagnosis does not stop at the call generation floor, but moves to the next floor and executes the door opening / closing diagnosis of that floor, so the user is erroneously in the diagnostic operation It is possible to prevent getting in the car. Moreover, since the door opening / closing diagnosis of the call generation floor is executed after the completion of the door opening / closing diagnosis of all the floors, a diagnosis omission can be prevented and the door opening / closing diagnosis can be surely executed.

<Door heavy floor door diagnosis process>
When opening and closing the door, the weight of the door may differ from floor to floor. In particular, a door on a reference floor (first floor) that is frequently boarded and exited or a floor that is easily affected by wind may be heavier than doors on other floors. Such a heavy door opening / closing is called a door heavy floor.

  FIG. 9 shows the door opening / closing diagnosis process including the door heavy floor.

  If the door heavy floor is included during execution of the door opening / closing diagnosis, the door opening / closing diagnosis is executed a plurality of times on the door heavy floor (ST61, ST62, ST63). When all door opening / closing diagnosis is completed, the diagnosis result is stored in the diagnosis result storage unit 35 (ST64, ST65).

  As described above, for the door heavy floor where the door is heavier than usual, by executing a plurality of door opening / closing diagnoses, it is possible to prevent erroneous diagnosis and obtain a reliable door opening / closing diagnosis result.

<Another embodiment of remote diagnosis driving method in group management>
In the above embodiment, when the diagnosis cycle arrives, remote diagnosis operation is performed one by one in a predetermined order for the units to which no call is assigned while performing group management operation.

  As another embodiment of the remote diagnosis operation method, when the diagnosis cycle arrives, the group diagnosis operation is performed, and the remote diagnosis operation is simultaneously performed on a plurality of units to which no call is assigned. . The remote diagnosis operation in this case is the same as the process in the case of executing the remote diagnosis operation one by one in a predetermined order.

  As described above, the remote diagnosis operation can be executed in a short time by simultaneously executing the remote diagnosis operation on a plurality of units to which no call is assigned, and the efficiency is dramatically improved.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
