DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagnostic operation apparatus for an elevator which performs various measurements and inspections by actually operating the elevator.

[0002]

2. Description of the Related Art In recent years, a monitoring device has been provided which constantly monitors an elevator during normal use, detects abnormality or failure of the elevator, and notifies the monitoring center of the abnormality. This monitoring device not only detects and reports abnormalities and failures as described above, but also transmits the operation information of the elevator obtained during monitoring to the monitoring center, and the operation information accumulated in the monitoring center is Used for maintenance and inspection of elevators.

[0003] By the way, operation information during normal use of an elevator is often affected by the operation of passengers. For example, the opening and closing time of a car door is lengthened (often in such cases) when the passenger holds or leans on the door during opening and closing. In this case, even if the monitoring device detects that the opening / closing time of the door has become long, it cannot determine whether the cause is that a stone is caught in the sill of the door or the operation of the passenger is the cause. . In consideration of such circumstances, Japanese Patent Publication No. 2-36512 has proposed an automatic inspection driving device that detects that there is no passenger in a car and performs an automatic inspection.

[0004]

The above-described conventional automatic inspection and driving apparatus can inspect equipment without influence by passengers, and collects and accumulates data on the operating state of equipment to change aging data. Thus, it is possible to predict the failure of the device and predict the life of the device. However, the above-described conventional automatic inspection driving device cannot inspect equipment that does not function in the normal use state of the elevator. For example, a safety device such as an up-limit switch or a down-limit switch does not operate in a normal use state, and operates only when an abnormality occurs. Therefore, the conventional automatic inspection and operation equipment cannot inspect these safety devices, and it is necessary for maintenance personnel to go to the site and operate the elevator, which requires time and effort. Was.

Since the monitoring system between each elevator and the monitoring center 2 is well known, its description is omitted.

Reference numeral 3 denotes a diagnostic driving device, which is a monitoring center 2
Performs a diagnostic operation of the elevator 1 in accordance with a predetermined procedure when a diagnostic operation command is issued via the communication line 4, and transmits the result of the diagnostic operation to the monitoring center 2 via the communication line 4. The diagnostic driving device 3 communicates with the monitoring center 2, a diagnostic driving command device 32 for performing a diagnostic driving according to a predetermined procedure, and an elevator control panel 11 based on a command from the diagnostic driving command device 32. It is composed of a high-speed operation command device 33 that outputs a high-speed operation command, a low-speed operation command device 34 that also outputs a low-speed operation command, and a diagnostic device 35 that inputs data from the elevator control panel 11 and performs necessary processing. .

The input of the low-speed operation command signal from the low-speed operation command device 34 to the elevator control panel 11 may be performed by the control panel low-speed operation device that directly inputs the low-speed operation signal to the elevator control panel 11 during the elevator installation work. good.

The diagnosing device 35 includes the elevator control panel 11
The state of the elevator 1 is output to the diagnostic operation command device 32 according to the data of the above, the required data among the data is stored, and the presence or absence of an abnormality or a failure is determined based on the data to determine whether the abnormality or the failure occurs. If so, it transmits this to the monitoring center 2 via the communication device 31.

[0012] Next, the operation of this embodiment with reference to the flowchart of diagnostic luck UtateSo location 3 shown in FIGS. 2 and 3 will be described. From the monitoring center 2, the diagnostic operation start time and the diagnostic operation end time are transmitted together with the diagnostic operation instruction signal, and these are input to the diagnostic operation instruction device 32.
Here, the diagnosis start time and the diagnosis operation end time are selected in a time zone in which the use of the elevator 1 is extremely small in consideration of the installation location of the elevator 1 and the purpose of use.

When a diagnostic operation command is issued, the diagnostic operation command device 32 determines whether or not the diagnostic operation start time has been reached (procedure S ₁ shown in FIG. 2).
It is determined whether a call for the car 13 or a hall call has been registered for a predetermined time before that time, for example, 30 minutes (step S ₂ ). Call 30 minutes is not registered, it is determined that the passenger has become completely Nii without being whether or not the current time is within the time zone of the diagnostic operation is determined (Step S _3), run the diagnostic operation if overtime Without waiting for the next diagnostic operation command. If it is within the time, it is determined from the signal from the diagnostic device 35 whether or not the position of the car 13 is on the lowest floor (step S ₄ ). make calls, move the elevator car 13 to the bottom floor by operating the high-speed operation command unit 33 (Step S _5). Car 13 when there initially in the lowest floor, the processing of steps S ₅ is not performed.

When the car 13 is moved to the destination floor by the above-described high-speed driving, it is not always necessary to use the hall call of the floor. Of course, the elevator standby command signal may be used.

While the car 13 is on the lowest floor, the diagnostic operation command device 32 commands the low speed operation command device 34 to increase the speed at low speed (step S ₆ ). By this, car 1
3 rises slowly. When a signal from the diagnostic device 35 has caused the car 13 to rise to 100 mm, that is, when the car 13 has passed the lowest floor and is now ready to operate the lower limit switch 15 ( Step S _7), the diagnostic operation command unit 32 outputs a slow descent command to the low-speed operation command device 34 (Step S _8), causing the car 13 at a low speed lowered.

The diagnostic operation command device 32 monitors whether or not the car 13 descends at a low speed and turns on the descending limit switch 15 based on a signal from the diagnostic device 35 (step S ₉ ). When lowering limit switch 15 is turned ON, the diagnostic operation command unit 32 outputs a slow increase command to the low-speed operation command device (Step S _10), when the car 13 reaches the lowermost floor position (Step S ₁₁ ), stops the output of the slow increase command (Step S _12). In the processing steps S _9, when the lowering limit switch 15 is turned ON, the diagnostic device 35 inputs data from the elevator control panel 11, the lowering limit switch 15 is turned ON, the ON of the lowering limit switch 15
Stores the stop of the car 13 and the stop position.

When the inspection of the lower limit switch 15 is completed by the processing of the above-described steps S _{6 to} S ₁₂ , the diagnostic operation command device 32 next makes a hall call on the top floor, activates the high speed operation command device 33 and activates the car. 13 is a move to the top floor (Step S _13), turn out the inspection of the raising limit switch 16 (Step S _14). This inspection is performed in accordance with the procedure S ₆ to S ₁₂ of inspection lowering limit switch 15, and a description thereof will be omitted. By this inspection, the data of the ascending limit switch 16 is stored in the diagnostic device 35.

As described above, when the inspection of the lower limit switch 15 and the upper limit switch 16 is completed, the diagnostic operation command device 32 performs necessary inspection in the high-speed operation state. That is, in order to move the car 13 currently on the top floor to the lowest floor, the diagnostic operation command device 32 makes a hall call for the lowest floor, and outputs a high-speed operation command to the high-speed operation command device 33 to the lowest floor. to (Step S _15). And car 13
There reaches the lowermost floor (Step S _16), the diagnostic operation command unit 32 creates a call top floor of hall, and outputs the high-speed operation command to the top floor to the high-speed operation command unit 33 (Step S _17). Thus, the car 13 is the high-speed operation from the lowest floor to the top floor, to reach the top floor floor (Step S _18).

During this high-speed operation, the diagnostic device 35 examines the start-up shock and the inclination of the acceleration at the time of starting, the variation of the speed at the time of high-speed running, and the like. The stop position and the like are checked, and the results are stored.

Next, in order to check the high-speed operation state at the time of descent, the diagnostic operation command device 32 makes a hall call on the lowest floor and issues a high-speed operation command to the high-speed operation command device 33 to the lowest floor. output (Step S _19). Thus, the car 13 is the high-speed operation from the top floor to the bottom floor, to reach the lowermost floor (Step S _20). Thereby, the diagnostic operation ends.

During the high-speed operation at the time of the descent, the diagnostic device 35, as in the case of the ascent, starts the shock at startup, the gradient of the acceleration, the variation of the speed at the time of high-speed running, the gradient of the deceleration, and the stop. Investigate shocks, stop positions, etc., and store the results.

During the diagnostic operation, the diagnostic device 35 determines whether or not the value is within the allowable range of the reference value each time necessary data is captured, stores the determination result, and captures it. When the data is out of the allowable range, the data is notified to the monitoring center 2 via the communication device 31 and the communication line 4. Here, the diagnostic device 35 does not actively report,
The data and the determination result can be transmitted to the monitoring center 2 by receiving a command from the monitoring center 2.

In the above description of the embodiment, the example of the diagnostic operation program stored in the diagnostic operation command device has been described. However, the diagnostic center is transmitted from the monitoring center every time the diagnostic operation is performed. Can also.

As described above, in the present embodiment, the high-speed operation command device and the low-speed operation command device are provided, and the diagnostic operation command device performs not only the diagnostic operation in the high-speed operation state but also the rising limit switch and the lower limit switch by the low-speed operation. Since the operation test is also performed, it is not necessary to perform these inspections at the time of the inspection work of the maintenance staff, and the time required for all the inspection work of the maintenance staff can be shortened and the inspection work can be efficiently performed.

Since the diagnostic operation in this embodiment is executed during a time when the elevator is not used, the collected data is collected and analyzed for a long period of time, and the data change due to wear of each equipment of the elevator is performed. Can be detected, and each device can be replaced before damage.
Furthermore, since the elevator is executed during a time period when the elevator is not used, maintenance work during the use time of the customer can be reduced, and customer dissatisfaction can be reduced. Further, in this embodiment, since the inspection and diagnosis of the elevator are performed in synchronization with the movement of the elevator, highly reliable inspection and diagnosis can be performed irrespective of the skill level of maintenance personnel.
