A communication means such as a public telephone line for connecting the remote monitoring computer 20 to the remote monitoring computer 20. Further, a maintenance computer 22 can be directly connected to a maintenance control device on site.

FIG. 2 is a schematic diagram showing data in the memory 11b. In FIG. 2, reference numeral 16 denotes moving the car 1 to a predetermined floor, opening and closing the door of the car 1 via the door opening / closing control device 3, and setting a time required for the opening / closing operation of the door at that time to a predetermined setting. This is an automatic test operation program that sets the floor to a door opening / closing abnormality if the time is longer than an hour. Reference numeral 17 denotes set date and time data in which the date and time at which the automatic test operation program 16 is executed is set. 15 determines whether or not the date and time to execute the automatic test operation program 16 has been reached based on the output of the clock 11c in the panel, and determines whether or not predetermined conditions are satisfied. This is a startup program for executing the test operation program 16.

The memory 11b, the automatic test operation program 16 and the CPU 11a move the car 1 to a predetermined floor, cause the door opening / closing control device 3 to open / close the door, and perform the door opening / closing operation for a predetermined time. In this case, a test means for judging the floor as a door opening / closing abnormality is constituted. The internal clock 11c, the set date / time data 17, and the start-up program 15 constitute start-up means for causing the CPU 11a to execute the automatic test operation program 16 at a preset date and time.

FIG. 3 is a flowchart showing the operation of the startup program 15. According to FIG.
Operation 5 will be described. This activation program 15
It is always operating by U11a. Then, based on the set date and time data 17, the automatic test operation program 16
(Step S1). If it is not within the reserved time zone, the automatic test operation program 16 is not executed (step S2).

On the other hand, if it is within the reserved time zone, it is next determined whether or not there is an elevator user based on the output from the in-car load detecting device 4 (step S3).
Here, the state where there is no passenger of the elevator means that the hall call and the car call are not registered and the car load is equal to or less than a predetermined value. When there is an elevator user, the automatic test operation program 16 is not executed (step S2).

On the other hand, if there is no elevator user,
Next, it is determined whether or not a high-priority operation such as a disaster control operation is being selected and, at the same time, whether or not the automatic operation mode is being performed (step S4). Then, when the operation having the higher priority is being selected or when the operation is not in the automatic operation mode, the automatic test operation program 16 is not executed (step S2).

On the other hand, when the operation with the higher priority is not being selected but in the automatic operation mode, it is next determined whether or not maintenance is being performed (step S5). If the maintenance is being performed, the automatic test operation program 16 is not executed (step S
2). If maintenance is not being performed, an automatic test operation is started. That is, the automatic test operation program 16 is executed. In the flowchart, a subroutine of the automatic test operation program is called (step S6).

FIG. 4 is a flowchart of the automatic test operation program 16. FIG. 5 is a flowchart of the automatic test operation program 16 following FIG. First, in FIG. 4, when the automatic test operation starts, first, the operation specifications of the automatic operation are checked (step S11). Here, the operation specifications of the automatic driving include, for example, display and notification of a car and a landing, availability of driving to a service cut floor, and the like. Thereafter, an operation flag for automatic driving is set based on the operation specification (step S12).

Thereafter, it is again checked whether or not an elevator user has been generated (step S13), and it is further checked whether or not maintenance is being performed (step S14). Test operation was suspended,
That is, the operation is returned to the normal operation (step S15), and thereafter, returns to the start program 15 (step S16).

On the other hand, if no elevator users have been generated and maintenance is not being performed, it is further determined that a high-priority operation such as a disaster control operation has been selected (step S19). Departure from reservation time slot (Step S
20) Further, after the start of the automatic test operation, it is confirmed whether or not the operation has not been completed even if a predetermined time has elapsed (step S21). If any of the conditions is satisfied, the automatic test operation is stopped. That is, the operation is returned to the normal operation (step S22), and thereafter, the automatic test operation on that day is not performed (step S23).

If none of the above cases applies, it is determined whether or not the automatic test operation has been completed. If the automatic test operation has been completed, the automatic test operation is normally terminated (step S27). To end the process.

On the other hand, if the automatic test operation has not been completed yet, the procedure goes to FIG. 5, in which the elevator (car 1) is first driven to the test floor, and the door is opened and closed at a predetermined speed and a predetermined torque. (Step S30). Then, the opening and closing times at that time are measured (step S31).

As a result, if the opening and closing times are longer than the first set time A (step S32), the floor is provisionally set to a "door opening / closing abnormal floor" (step S33).
In addition, at the time of retest, if processed in this step,
This floor is set as the “door opening and closing abnormal floor”.

The opening and closing times are set to a second set time B.
If it is larger than the first set time A (step S35), the floor is provisionally set to the "door opening / closing abnormality warning floor" (step S36). In addition, at the time of the retest, when the processing is performed in this step, the floor is set as the “door opening / closing abnormality warning floor”.

Further, when the opening and closing times are longer than the third set time C and smaller than the second set time B (step S38), the floor is provisionally set to the "door opening / closing abnormality caution floor". Is performed (step S39). At the time of retest,
When the processing is performed in this step, the floor is set as the “door opening / closing abnormality caution floor”.

When the floor is provisionally set to the "door opening / closing abnormality floor", the "door opening / closing abnormality alarm floor" or the "door opening / closing abnormality warning floor", the floor is retested in the automatic door opening / closing automatic test operation. (Step S41).

On the other hand, when the opening and closing times do not satisfy any of the above conditions, it is concluded that the opening and closing times are smaller than the third set time C as a result. ,
The floor is set as normal (step S42).

Further, at a predetermined floor,
When the measurement of the closing time is completed, the target test floor is updated (step S44). The test floor is updated in the order of the top floor, top floor-1, top floor-2,.

Then, it is determined whether the automatic test operation has been performed from the top floor to the bottom floor (step S4).
5) If implemented, it is determined whether there is a retest floor for the automatic test operation (step S46). If there is a retest floor, the retest floor is set as the test floor (step S46). S47). The results of these tests are reported to the remote monitoring computer 20 as a remote monitoring device via the communication means 21.

The start date, time zone, check interval, and the like of the automatic test operation set in the set date and time data 17 are transmitted via the communication means 21 to the remote monitoring computer 20.
It can be set from. Alternatively, even when the elevator is a multi-car, these data can be set from the remote monitoring computer 20 or the maintenance computer 22 for each car. The automatic test operation is basically performed on all floors, but a service cut floor (a floor where the automatic test operation is not performed) can be set as described above.

In the measurement of the door opening and closing time, a load fluctuation at a stage that does not affect the door opening / closing operation in the normal operation can be detected for each floor. It is designed to be able to detect anomalies and signs of anomalies in response to changes in the state and the state in which each device is familiar after installation, and also in heavy doors and large wind pressure floors.

As described above, the first set time A,
By determining the abnormality by providing the second set time B and the third set time C, the mechanical load is increased, but the level is not at the level that leads to the improper door opening / closing failure (caution). It is possible to determine whether there is a certain (alarm) or a door opening / closing failure (abnormal), and these determination results are reported to a remote monitoring computer 20 as a remote monitoring device. In addition, the automatic check operation is performed again on the floor in which an abnormal value is detected in the opening and closing of the door as a result of the automatic check operation, and the pass / fail judgment is performed together with the previous result, so that erroneous detection is prevented. Note that the first set time A,
The second set time B and the third set time C can be set from the remote monitoring computer 20 or the maintenance computer 22.

Further, the check result is a door opening for each floor,
Three times are stored for each door closing (if one time / month is checked, three months' worth of data is retained), and from the fourth time onward, data is sequentially updated from the oldest data.

In the automatic test operation, the check is canceled for the floor where the door cannot be opened and closed, and the check is started again from the next floor.

In addition, during the automatic test operation, the following operation is performed with respect to the display / notification during the automatic test operation so that even if the user gets into the car 1 by mistake, the user can know that the inspection is being performed. You. These settings can be enabled / disabled from the remote monitoring computer 20 or the maintenance computer. a. Turn off the lights in the car and turn on the door open button (reverse operation when disabled) b. Enable landing display (indicator, direction light) c. Hall information (hall lantern), invalid car top and bottom chimes d. Validate hall information "under inspection" display e. Enable car display (indicator, direction light) f. Speech synthesis or voice guidance "Check now" is enabled g. Enable "Inspection" display for car information

Further, as the operation is expressed in the above-mentioned flowchart, even if the elevator is in the automatic test operation, the hall test and the car call are registered, and the automatic test operation is immediately stopped and registered in the elevator. It operates in response to a hall call and a car call.

The clock 11c in the panel uses the clock counted from the remote monitoring computer 20 or the maintenance computer 22 in the panel based on the clock from the remote monitoring computer 20 or the maintenance computer 22, and adjusts the time from the remote monitoring computer 20 or the maintenance computer 22 as needed. Shall be performed. Also, if it is assumed that a time lag has occurred due to a power failure, etc.,
It is assumed that the time data can be corrected at an early stage. If the time data cannot be corrected, the operation is invalidated so that the automatic test operation is not performed at the wrong time. Further, when a time shift occurs due to a memory abnormality or the like, a request for time data is made to the remote monitoring computer 20. (The time data request can be set to valid / invalid.) If the time data request does not recover, the operation is disabled so that the automatic test operation is not performed at the wrong time. Is carried out and the correction function down information is held in the panel and transmitted to the remote monitoring computer 20.

Further, it is assumed that the set date and time data 17 has a calendar function including day of the week data. To set the date and time for performing the automatic test operation, for example, "automatic test operation is performed on the first Sunday of every month" Can be set for each day of the week.

The check interval (monthly automatic test operation day) can be set as follows. a) Automatic test operation date and time for each month can be set (for example, “automatic test operation is performed from 1:00 to 5:00 on March 14 and from 2:00 to 6:00 on April 23 in March”). After setting, the automatic check device determines the date and time and starts the automatic test operation.) B) Setting for each day of the week is possible (for example, setting such as "automatic inspection on the first Sunday of every month"). The automatic check device determines the date and time and performs the automatic test operation.) C) The automatic test operation date and time can be set to the first test date and the second test date. (That is, it is possible to set a spare day when the test is not completed on the first test day.) D) It is possible to set up to 31 test dates and times per month. (Responding to customer requests for automatic test driving every day.)

In the elevator door opening / closing automatic check device having such a configuration, during a pre-reserved time period when there is no user such as at night, all floors (service cut floors in which no inspection operation is performed are set according to the setting). The door is automatically opened and closed, and an abnormality determination of door opening / closing is performed for each floor. Then, in the event of an abnormality, a notification is sent to the remote equipment monitoring center. or,
The door opening / closing check can be performed by manual operation for confirmation at the time of maintenance.
