[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator diagnosis and operation apparatus, and more particularly to an elevator diagnosis and operation apparatus that collects data during operation of an elevator and performs measurement and diagnosis to prevent a failure.

[0002]

2. Description of the Related Art In general, when a failure occurs in an elevator, it not only causes a lot of trouble to many users,
Depending on the type of failure, there is a case where the danger is given to the user. To cope with this, conventionally, a monitoring center that remotely monitors a large number of elevators is provided, and when an accident corresponding to a predetermined serious accident is detected in a certain elevator,
This is reported to the monitoring center via a communication line, and the monitoring center receiving this report takes necessary measures for ensuring safety. In addition, in recent years, during operation of the elevator, various data such as a main contactor and a rotary encoder relating to operation control are collected, and whether or not the data is within a preset range, and whether various devices are normally operating. Elevator diagnostic driving devices that attempt to prevent failure by measuring and diagnosing whether or not to operate have come to be used.

[0003]

However, the conventional diagnostic operation apparatus for an elevator is generally performed in a situation where a clerk is not present, and it is determined whether or not the diagnostic operation is normally performed. Since the confirmation has not been performed, if a trouble occurs during the execution of the diagnostic operation, the diagnostic operation remains stagnant.

It is an object of the present invention to provide an elevator diagnostic operation apparatus which can easily return to normal operation when a trouble occurs during execution of diagnostic operation.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an elevator diagnostic driving apparatus having a diagnostic driving apparatus for performing a diagnostic operation by moving a car according to a predetermined procedure. Means for setting a permissible execution time from the start to the end of the diagnosis, and a permissible time setting means for setting a permissible time for performing the diagnosis operation. A return means for returning to a state is provided.

In the elevator diagnostic operation apparatus according to the present invention, as described above, the diagnostic operation permissible time setting means sets the permissible execution time from the start to the end of the diagnosis, so that the time during which the diagnostic operation is performed is executed. When the allowable time is exceeded, the diagnostic operation is stopped by the return means and returned to the normal operation state, so even if a trouble occurs during the diagnostic operation, the diagnostic operation time is executed. When the allowable time is exceeded, the normal operation state is restored, so that it is possible to prevent the diagnostic operation from being stagnated as in the related art.

It is constituted by operation permissible time setting means. The progress of the diagnostic operation and the permissible execution time are stored in the diagnostic operation setting storage unit 3.
3 and hereinafter referred to as status.

FIG. 12 shows data obtained by coding an operation pattern of the diagnostic operation for distinguishing an execution pattern such as how many times per month the high-speed diagnostic operation and the low-speed diagnostic operation are performed. This is stored in the storage unit 33 and is hereinafter referred to as a diagnostic operation mode. FIG.
Reference numeral 3 denotes a high-speed operation command unit 35 in which the diagnostic operation command unit 32 responds to the occurrence of some abnormality in the elevator 1 that is performing the diagnostic operation or a case where it is necessary to forcibly stop the diagnostic operation. Alternatively, a condition for prohibiting a command to the low-speed operation command unit 36 is shown, and this condition is also stored in the diagnostic operation setting storage unit 33.

Next, the diagnostic operation of the diagnostic operation device for an elevator will be described. The diagnostic operation command unit 32 is configured to perform the processing 1, the processing 2, the processing 3, and the processing 4 shown in FIG. 2 at the same time, and to repeatedly execute each processing. For example, when processing 1 is executed and processing contents to be described later are completed, processing 1 is executed again.

First, the process 1 will be described. The diagnostic operation command unit 32 follows the above-mentioned diagnostic master data stored in the diagnostic operation setting storage unit 33, and passes the elevator through the high-speed operation command unit 35 and the low-speed operation command unit 36. 1 is operation-controlled. The flowchart at this time is shown in FIG. When the process 1 is executed, it is determined in step S101 whether the current date and time is the diagnostic operation start date registered in the diagnostic master data and is within a time range in which the diagnostic operation can be performed. If it is within the time range in which the diagnostic operation can be performed, step S
The process proceeds to step S102, but if not, the diagnostic operation must not be performed. Therefore, the process proceeds to step S136 shown in FIG. 5, where a code “0” irrelevant to the diagnostic operation is stored as the status, the process 1 is terminated, and the process returns to the step S136. The process is repeated from S101.

When proceeding to step S102, it is determined whether or not the callless duration 6b in FIG. 9 is equal to or greater than a preset callless time limit in order to determine whether or not there is a customer of the elevator 1. I do. Although not described in the flowchart, when the door of the car 13 and the landing door associated therewith are open, the no-call time period is not established, and the no-call time period is satisfied only when the above-mentioned door is closed. It is a premise. Therefore, if no car call or hall call is frequently registered, the no-call time limit is not established as a matter of course, and in such a situation, the process proceeds to step S136 and the process 1 ends as in the case described above.

On the other hand, if the registration of the car call or the hall call has occurred for a certain period or more, the process proceeds to step S103 assuming that the no-call time limit has been established, and proceeds to the diagnosis master data 6 stored in the diagnosis operation setting storage unit 33. Diagnostic operation mode 6a is referred to. Subsequently, in step S104, it is determined what the diagnostic operation mode 6a referred to in step S103 is. As a result, in the case of the diagnostic operation mode “3” or “4” shown in FIG. 12, since only the high-speed diagnostic operation is performed, the process proceeds to step S127 in FIG. However, in the case of the diagnostic operation mode “1” or “2”, the low-speed diagnostic operation and the high-speed diagnostic operation are performed, and the process proceeds to step S105. From step S105 to before step S108, the car 1 is used to perform diagnostic operation of the elevator 1.
3 shows a process for positioning No. 3 at the lowest floor for diagnostic driving. In step S105, it is determined whether the car 13 is located at the lowest floor stored in the diagnostic operation setting storage unit 33 as a start floor for starting diagnostic operation, and if it is determined that the car 13 is at that position, the process proceeds to step S108. On the other hand, if it is determined that the car is not located at that position, the process proceeds to step S106 to position the car 13 on the lowest floor, and the high-speed operation command unit 35 performs call registration of the lowest floor, After setting the status “1”, the process proceeds to step S107.

In step S107, step S106
It is determined whether or not the car 13 is located at the lowest floor by the call of the lowest floor registered in the above. If not, the determination is repeated until the car 13 is located at the lowest floor. When the determination is made, the process proceeds to step S108. From step S108 to step S115, the above-described DLS1
5 shows the process of diagnosing DLS15, but when diagnosing DLS15, in order to accurately measure the operating position, move once a predetermined distance in the direction away from DLS15 with reference to the landing level of the lowest floor, and then measure To start. Therefore, in step S108, after confirming that the door is closed, the low speed diagnosis operation command unit 36 outputs a low speed ascent operation command to the elevator 1, and the status "2"
Is set. After that, in step S109, the process waits until the car 13 ascends by 400 mm as the above-mentioned predetermined distance in the command of step S108.
At step S110, the low speed diagnosis operation command unit 36 stops the low speed ascent operation command for the elevator 1. Thereafter, the low-speed operation command section 36 outputs a low-speed lowering operation command to measure the operation position of the DLS 15 and lowers the car 13. In step S111, the process waits until the DLS 15 operates due to the lowering of the car 13 in step S110. When the DLS 15 operates, the low-speed diagnostic operation instruction unit 36 stops the low-speed downward operation instruction to the elevator 1 in step S112. Then, in order to position the car 13 at the lowest floor level,
In step S113 in FIG. 4, the low-speed diagnosis operation command unit 36 outputs a low-speed ascent operation command to the elevator 1.
In step S114, the determination is repeatedly performed until the car 13 is located at the lowest floor level. If it is determined that the car 13 is located at the lowest floor level, the low-speed diagnosis operation command unit 36 performs the ascending operation to the elevator 1 in step S115. Stop the command.

Subsequently, from step S116 to step S
At 117, a process of positioning the car 13 on the top floor to perform the ULS 16 diagnosis is performed. First, in step S116, the high-speed operation command section 35 registers a call for the top floor, sets a status "3", and proceeds to step S117. In step S117, step S
With the call for the top floor registered in 116, it is determined whether the car 13 is located on the top floor, and if not, the determination is repeated until the car 13 is located on the top floor. When it is determined, the process proceeds to step S118. In step S118, according to steps S108 to S115, which are diagnostic processes of the DLS 15, the ascending goes down, the lowest floor becomes the top floor, and the DLS is read as ULS, and the ULS 16 is diagnosed as a similar process.
The car 13 is located at the top floor level. ULS16
In the same processing as that in step S108 in the case of the diagnosis, the status "4" is set.

Steps S119 to S135B shown in FIG. 5 show a diagnosis relating to the riding comfort at the time of high-speed running.
In step 20, a process for positioning the car 13 at the lowest floor is performed as a start reference for performing the high-speed diagnostic operation.

In step S119, the high-speed operation command unit 3
5 performs call registration of the lowest floor, sets status "5", and proceeds to step S120. In step S120, it is determined whether or not the car 13 is located at the lowest floor by the call for the lowest floor registered in step S119. The determination is repeated during the period, and when it is determined that the position is determined, the process proceeds to step S121. Step S121
Steps S126B to S126B describe the processing procedure of the high-speed diagnosis by the high-speed ascent operation from the lowest floor to the top floor and the high-speed diagnosis by the high-speed descent operation from the top floor to the lowest floor. Then, the high-speed operation command unit 3
5, the call registration of the top floor is performed, the status "6" is set, and the process proceeds to step S122. In step S122, it is determined whether or not the car 13 is located on the top floor by the call for the top floor registered in step S121, and if not, the determination is repeated until the car 13 is located on the top floor. When it is determined that it is located, the process proceeds to step S123.

In order to make the high-speed diagnosis by the high-speed ascent operation from the lowest floor to the highest floor effective only when the car 13 is unmanned, step S123 is executed in step S123.
It is determined whether the high-speed ascending operation performed in step 1 and step S122 is performed in an unmanned straight operation by the diagnostic operation command unit 3.
2 determines, if not unattended, step S11
Return to step 9 and drive from the bottom floor to the top floor again.

On the other hand, in the case of unmanned straight driving, high-speed diagnosis is enabled, and the routine proceeds to step S124.
In step S124, the high-speed operation command section 35 registers the call for the lowest floor, sets the status “7”, and proceeds to step S125. In step S125, it is determined whether the car 13 is located at the lowest floor by the call for the lowest floor registered in step S124, and if not, the determination is repeated until the car 13 is located at the lowest floor. Do,
When it is determined that it is located, the process proceeds to step S126.
In step S126, similar to step S123, the high-speed diagnosis by the high-speed descending operation from the top floor to the lowest floor is effective only when the car 13 is unmanned. Therefore, it is determined whether or not the car 13 is unmanned. judge. If the vehicle is not unmanned, the high-speed operation command unit 35 registers the call of the top floor in step S126A to execute the high-speed diagnosis by the high-speed descent operation from the top floor again.
At B, it is determined whether or not the car 13 is located on the top floor, and if not, the determination is repeated until the car 13 is located on the top floor. carry out. On the other hand, in the case of unmanned straight driving, the above-mentioned high-speed diagnosis is enabled,
Since a series of diagnostic operations is completed, the process proceeds to step S136.

Steps S127 to S135B
Is a procedure for processing when the diagnostic operation mode is “3” or “4” in step S104 described above. The diagnostic operation mode stored in the diagnostic operation setting storage unit 33 in advance without performing the low-speed diagnostic operation is described. This is a processing procedure in which only the high-speed diagnostic operation is performed between the floor and the lower floor. In this case, as preparation for starting the diagnostic operation, it is necessary to determine whether the car 13 is located on the lower floor where the diagnostic operation is performed.
At 27, the diagnostic operation command unit 32 determines whether the car 13 is located on the lower floor, and if it is not located,
In steps S128 to S135B, the same processing as in steps S119 to S126B is performed. On the other hand, when the car 13 is already located on the lower floor where the diagnostic operation is performed, the processing is performed from step S130 to step S130 without performing steps S128 to S129 in the same manner as the procedure from step S121 described above.
When a series of processes of the low-speed diagnosis operation or the high-speed diagnosis operation up to now is completed, the status “0” is set in step S136, and the process 1 ends.

Next, processing 2 will be described. Processing 2
According to the status set in the process 1, the diagnostic operation instructing unit 32 sets the count-up of a timer for setting the permissible execution time for each status and sets ON / OFF of a timeout flag.
In step S201 shown in FIG. 6, it is determined whether the current status is status "1". If the status is other than status "1", the process proceeds to step S205. On the other hand, if it is determined that the status is “1”, the process proceeds to step S202, the timeout timer (1) for the status “1” is counted up, and the process proceeds to step S203. This step S2
At 03, the time-out timer (1) determines whether or not the time-out period corresponding to the status "1" is 3 minutes or more, and if not, step S20.
Go to 5. On the other hand, if the time-out timer (1) counts up for 3 minutes or more, it is determined that the arrival at the lowest floor for the diagnosis of the DLS 15 was not possible even after 3 minutes due to frequent car calls by the user. And step S20
At 4, the timeout flag is turned on. As a result of turning on the time-out flag, the return means operates assuming that the corresponding permissible execution time has elapsed as described later, and gives a command to return to normal operation to the elevator control device 11 via the diagnostic operation command unit 32. Become. After turning on the timeout flag, the process proceeds to step S205.

In step S205, the previous step S2
01, similarly to the processing executed in step S204, it is determined whether the current state is any of the statuses "2" to "7", and if the status is applicable, the timeout timer for each status corresponding to the status is counted up. .
Then, as a result, it is determined whether or not each timeout timer is equal to or longer than the respective timeout period. If the timeout timer is equal to or longer than the timeout period, the timeout flag is turned on.

In step S206, it is determined whether or not all the times required for the diagnostic operation time have timed out. In this case as well, the current state is the status "1" to the same as in steps S201 to S205 described above.
It is determined whether it is any of “7”, and if not, the process proceeds to step S210. On the other hand, if it is determined that the status is applicable, the process proceeds to step S207, and the status is set to “1”.
The timeout timer (8) for "7" is counted up, and the flow advances to step S208. In step S208, the timeout timer (8) determines whether or not the total timeout timer of the statuses "1" to "7" is 15 minutes or more. If the timeout timer has not reached 15 minutes, the process proceeds to step S210. On the other hand, if the time-out timer (8) has counted up to 15 minutes or more, it is determined that the diagnostic operation could not be completed even after 15 minutes since the car calls and the like by the user occurred frequently, and in step S209, Turn on the timeout flag. In step S210, status "0"
Is determined, and if not applicable, the process 2 is terminated, and the process is repeated from step S201 of the process 2 again. On the other hand, if it is applicable, it is determined that the diagnostic operation is not being performed, the timeout timers (1) to (8) are cleared to zero in step S211 and the process 2 is terminated, and the process is repeated from step S201 of the process 2 again. .

Next, processing 3 will be described. The diagnostic operation processing unit 32 of the process 3 performs the diagnostic operation instruction unit when the diagnostic operation is performed and the elevator 1 needs to stop the diagnostic operation for some reason or forcibly stop the diagnostic operation. Reference numeral 32 denotes a procedure for prohibiting a command to the high-speed operation command unit 35 or the low-speed operation command unit 36. First, in step S301 shown in FIG. 7, in order to determine whether or not the diagnostic operation is currently being performed, the current status is "1" to "7".
Is determined, and the status “1” to
If it is not any of "7", the diagnostic operation is not being performed, and thus the process 3 is terminated, and the process is repeated again from step S301. On the other hand, if the status is “1 to 7”, the process proceeds to step S302, and it is determined whether the timeout flag is on. If the timeout flag is on, the process proceeds to step S304, and the time during which the diagnostic operation is being executed has exceeded the entire allowable execution time, or the execution time of the individual diagnostic operation is set to the corresponding allowable execution time. If it is exceeded, the return means is activated, and the diagnostic operation command unit 32 gives a command to the elevator control device 11 to stop the diagnostic operation and return to the normal operation.

On the other hand, if the timeout flag has not been turned on, the flow advances to step S303 to determine whether or not the prohibition condition shown in FIG. 13 has been satisfied, and any one of the items corresponding to the prohibition condition has been satisfied. At this time, the prohibition condition is satisfied, and the process proceeds to step S304. On the other hand, if no prohibition condition is satisfied, the process 3 is terminated, and the process is repeated again from the step S301. When the process proceeds to step S304, the diagnostic operation command unit 32 cancels the diagnostic operation command to the high-speed operation command unit 35 or the low-speed operation command unit 36 in order to stop the ongoing diagnostic operation.

Next, processing 4 will be described. The process 4 is performed by the diagnostic unit 38. First, in step S401 shown in FIG. 8, it is determined that the current status is any of the statuses "2", "4", "6", and "7" indicating that the diagnostic operation is being performed. Judge, and if not applicable, end processing 4.
The processing is repeated again from step S401. On the other hand, if the status corresponds to any of these, steps S402, S403, and S404 are processed simultaneously. In step S402, the diagnosis of the ULS 16 and the DLS 15 is performed. When the status is "2" or "4", the diagnosis of the DLS 15 is performed in steps S108 to S112 of the above-described process 1, and the diagnosis process of the ULS 16 is performed in step S118. carry out. The result is stored in the diagnosis result storage unit 3 shown in FIG.
4 is stored in the corresponding table 7i, 7j of the storage table.

In step S403, the running performance is diagnosed, and the status is "6" or "7".
The diagnostic processing is performed at the time of. The traveling performance includes acceleration time during ascending and descending operations reflecting the riding comfort of the car 13, steady speed after completion of acceleration, deceleration time during deceleration before arrival at the destination floor, arrival time at arrival at the destination floor. The diagnosis processing at the floor level is performed, and the results are stored in the corresponding tables 7a to 7h of the storage tables in the diagnosis result storage unit 34 shown in FIG.
To be stored. In step S404, a diagnosis of the door opening / closing performance is performed. When the status is "6" or "7", a diagnosis process is performed. As the door opening / closing performance, the door opening / closing time on the upper floor and the lower floor where the diagnostic operation is performed is diagnosed. The results are also stored in the corresponding tables 7k to 7n of the storage tables in the diagnosis result storage unit 34 shown in FIG.

As can be seen from the above description, the allowable execution time indicated as the timeout period corresponding to each of the statuses "1" to "7" and "1 to 7" in FIG. The means is provided in the diagnostic operation setting storage unit 33, and when it is determined that the time during which the diagnostic operation is being executed has exceeded the permissible execution time by using the timer means 37 for measuring the time during which the diagnostic operation is being executed, A return means for stopping the operation and returning to the normal operation is provided in the diagnostic operation command unit 32, and this return means determines whether the allowable execution time has been exceeded by determining whether or not the timeout flag is on. Specifically, when the elevator is performing the diagnostic operation, as shown in FIG. 11, the execution allowable time corresponding to each of the statuses “1” to “7” is measured by a timeout timer, and the entire diagnostic operation is performed. The permissible execution time corresponding to the statuses “1 to 7” is measured by a timeout timer, and whether the permissible execution time has exceeded is determined by whether or not a timeout flag is on. As described above, when the time during which the diagnostic operation in which the timeout flag is on exceeds the allowable execution time exceeds the allowable execution time, the diagnostic operation is stopped, and the return means for returning to the normal operation is operated. Even if some trouble occurs in the above, the diagnostic operation can be shifted to the normal operation without stagnation.

Moreover, since these diagnostic results can be stored in the diagnostic result storage section 34 and reported to the monitoring center from the communication section 31, the diagnostic results and trouble occurrence can be easily monitored. For this reason, although not described in the above-described embodiment, it is possible to store the execution record history of a series of diagnostic operations in the diagnostic result storage unit 34 so that the execution results of the diagnostic operation can be confirmed. it can. The execution result can include the diagnostic operation start date and time, the time required until the diagnostic operation ends, a graph indicating whether the operation has been completed normally, a cause flag for when the operation has not been completed normally, and the like. Further, in the above-described embodiment, the rope type elevator has been described, but the present invention can be similarly applied to a hydraulic type elevator.

[0034]

As described above, the diagnostic operation apparatus for an elevator according to the present invention is provided with the diagnostic operation execution allowable time setting means for individually setting the allowable operation time for the individual operation or the entire diagnostic operation. When it is determined that the execution time has exceeded the permissible execution time, the return means for stopping the diagnostic operation and returning to the normal operation is provided.Even if any trouble occurs during the execution of the diagnostic operation, The diagnostic operation can be shifted to the normal operation without stagnation.
