Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator control device, and more particularly to an elevator control device suitable for maintaining the performance of an elevator that remains unused for a long time.

[Conventional technology]

Conventionally, elevators were disclosed in Japanese Patent Application Laid-open No. 51-137257, 53.
- As described in Publication No. 18150, etc., when an elevator user operates a signal input device, etc. inside the car or at the entrance/exit of the landing, a car call signal is sent to the elevator control device to start operation. It had become.

[Problem to be solved by the invention]

In the above conventional technology, the elevator is operated by the user's car call operation, so if the call operation is not performed for a long period of time, such as an elevator installed in a building that is opened seasonally, the outage period will be extended. However, there was a problem in that the car drive system and the opening/closing system for the entrance/exit door at the landing ran out of oil, reducing driving performance.

An object of the present invention is to provide an elevator control device that prevents deterioration of operating performance.

[Means to solve the problem]

The second object is achieved by providing an elevator control device with means for detecting the absence of a car call for a long period of time and means for automatically generating a car call.

[Effect]

The elevator control device receives signals from the signal devices operated by the user at the entrances and exits of the first floor and the hall, makes a car call, and operates to drive the car to the arrival floor based on the user's instructions. do. Here, a car call is automatically generated within the elevator control device after a predetermined period of time has elapsed since the last signal from the signal device. As a result, it is possible to prevent deterioration in driving performance due to the car being operated as a car and not being used for a long time.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. The elevator is composed of a power converter 2, an electric motor 3 in which a mesh sheave 4 and a pulse generator 7 are directly connected through a rotating shaft, an operation control circuit 9, and a car call processing circuit 8. The car call processing circuit 8 is composed of an arithmetic processor 17, a storage circuit 16, an external input processor 5, 18, and a common address and data information bus 19. A destination indicator 12 is installed at the elevator seat 6, and a use request indicator 13, 14 is installed at the arrival floor 10°11.

The destination indicator 12 outputs a destination indicator signal S, according to the user's operation, and the usage request indicator 13-14 outputs a usage request signal SIF, 82F.

The signals SC, SIF and 82F are sent to the external input processor 15.
The reception is the data Sc of the formation that was processed by the arithmetic processor 17.
*, to SIF' and to 82F*. In the figure, 1 is the power supply and 5 is the balance weight.

FIG. 2 shows the flow of processing by the arithmetic processor 17 in the car call processing circuit 8 of FIG. The arithmetic processor 17
As shown in Figure (a), the power-on post-processing 100 initializes the devices constituting the car call processing circuit 8. Next, in process 200, the calculation interval is managed to be a predetermined time,
After processing 300 is performed, processing is performed in processing 200. In process 300, the process shown in FIG. 2(b) is performed. First, in step 310, it is determined whether there is a destination instruction signal Sc* from the car. If there is sc*, process 340
Call the name and create it. If S, * is absent, process 3
20, it is determined whether there is a use request signal 81 "*" or "*" 82. If there is, the process 340 is performed in the same way as in the process 310. After the process 34-0, the operation control circuit 9 A process 350 is performed to determine whether or not there is an arrival signal SR indicating that the vehicle has arrived at the requested floor.
If there is, the call will be canceled although it will correspond to the arrival floor in step 360. Then, the process moves to step 370, in which the floor information requested by the user is transmitted to the operation control circuit 9 as a destination signal 8T in response to the call.

If there is no Sl "* or F2F* in process 320, process 33
It is determined whether the value of the counter G for detecting the time when the car is not called after reaching 0 is larger than a predetermined value. The counter G is secured in a write-free area of the memory circuit 16. Since the car call processing circuit 8 performs calculations at fixed time intervals, the value of G is proportional to time. If there have been no car calls for a while, the value of G is smaller than the predetermined value, so processing 410 is executed and only the constant is added.

If there is no car call for a predetermined period of time, G becomes larger than a predetermined value, processing 380 is executed, and a car call is automatically created.

A detailed flowchart of process 380 is shown in FIG. Memory circuit 1
6, a driving history table is defined and used to detect that a predetermined driving was performed by automatic car call. In this example, the predetermined operation is to stop at each floor and perform two ascending and descending operations once. In process 381, it is determined whether a predetermined operation has been performed. A conceptual diagram of the driving history table is shown in FIG.

FIG. 4(a) shows the state of the operation history table at the beginning of automatic operation, when the car is on the floor, the doors have been opened and closed, and the preparation for ascending operation has been completed. If you continue the second ascending operation as soon as you arrive at the second floor and open and close the door, Figure 4 (a)
The column of the table specified by the vertical position 2FL and horizontal position UP changes from rr OI+ to rr 1 n. When the specified operation is performed, all columns in the operation history table are rr ], ++
As a result, the state shown in FIG. 4(b) is reached, and the calculation proceeds to step 382, where a flag is automatically set to notify the end of creating a car call. Thereafter, the driving history table is cleared in step 383.

If the conditions are not satisfied in process 381, a predetermined car call is made, and in this example, a car call for all floors is created.

Next, in step 390, the automatic car call creation flag is checked, and when the flag is set, arithmetic processing is performed to clear the counter G.

After processing 370, the operation control circuit 9 controls the power converter 2 to drive the electric motor 3 and move the seat 6 based on the destination signal ST. The speed and position are detected by the signal Sp from the pulse generator 7. This allows the vehicle to land stably on the destination floor and sends an arrival signal SR.

A detailed flowchart of process 340 is shown in FIG. Processing 341
, 34.2, when an automatic call is occurring, the counter G is
Make sure not to set it to O. And processing 343, 344
Therefore, only the calls requested by the user are created. Thereby, even if there is a user while the automatic car call is occurring, the automatic car call is interrupted and the user's car call can be prioritized.

According to this embodiment, even if the car is not called by a user for a long period of time, automatic operation will be performed at appropriate time intervals.
Maintains elevator operating performance. Furthermore, even if a person wishes to use the elevator while a car call is being automatically generated, the system immediately switches to normal operation, so there is no deterioration in service to the user. Furthermore, since an arithmetic processor such as a microprocessor is used in the car call processing circuit, the automatic car call pattern can be flexibly set according to the building in which it is installed.

〔Effect of the invention〕

According to the present invention, the operational performance of the elevator can be maintained without reducing safety.
