Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator monitoring device, and in particular,
The present invention relates to an elevator monitoring device that can collectively manage the monitoring and control of the operation status of elevators.

[Prior Art] In recent years, elevator monitoring devices have come to use CRTs for display on monitoring panels. As a conventional elevator monitoring device of this kind, Japanese Patent Application Laid-Open No. 61-2
Techniques disclosed in Japanese Patent Application Publication No. 87674 and Japanese Patent Application Laid-open No. 1-220689 can be mentioned.

These elevator monitoring devices monitor the operation status of all the elevators in multiple elevator banks in a building, and also operate external devices such as switches or light pens in emergencies and when necessary, and manually transmit predetermined operation control data. and issues various commands to the elevator bank. For example, at a predetermined time, the elevator monitoring side issues predetermined operation control commands to the elevator bank, such as operation at work, operation at lunch, and operation at clock out. controls the operation of the In addition, a clock is installed on the elevator group control panel of each elevator bank, and according to the clock, it performs its own operation control and displays the time on the displays in the hall and in the elevator car.

[Problems to be Solved by the Invention] However, in the conventional elevator monitoring device as described in -, the clock of the elevator group control panel and the clock of the elevator monitoring panel are each independently arranged.

Therefore, if the operation of the elevator is controlled based on the time of the clock on the elevator monitoring panel, the time displayed for information in each elevator car may not match and differ. Furthermore, the operating status of the elevators may differ from bank to bank depending on how fast or slow the clocks installed in the group control panel of each elevator bank are. Furthermore, due to the time difference between the elevator monitoring panel clock and the building clock, or the time difference between the elevator group control panel time and the building clock, the operation control of the entire elevator and other building equipment (e.g. , security, etc.) sometimes did not match. This has caused inconvenience to passengers and other elevator users, as well as giving them a sense of distrust.

Therefore, in this invention, the time on the building clock, the time on the elevator monitoring panel, and the time on the group control panel of each elevator bank are all matched, so that the time display and the operation of the elevators between each bank are accurate. It is an object of the present invention to provide an elevator monitoring device that is capable of controlling the operation of the entire elevator and temporally matching the control of other equipment in the building.

[Means for Solving the Problems] An elevator monitoring device according to the present invention includes a clock whose time is adjusted by a predetermined time signal, monitors the operation status of the elevator, and sends a predetermined signal to each elevator bank. Elevator group management means includes a clock whose time is adjusted by a time signal similar to the time signal, and manages a group of elevators in accordance with each signal from the elevator monitoring means. , and a elevator transport control means for actually controlling the operation of the elevators according to commands from the elevator group management means.

[Operation] In the present invention, at the same time as the time of the elevator monitoring means is adjusted by a predetermined time signal, the time of the elevator group management means is also adjusted by a time signal similar to the time signal. For example, by using the time signal from the building clock, the time of the building clock, the old time of the elevator monitoring means, and the old time of the elevator group management means of each bank are corrected. The operation of monitoring the operation status of the elevators and the signal transmission operation by the elevator monitoring means, the group management operation of the elevators by the elevator group management means, and the actual operation control operation of the elevators by the elevator operation control means can be made substantially the same. It can be roughly matched in time.

In this type of elevator monitoring device, each elevator group management controller (30) and elevator supervisory controller (40) are each equipped with a clock (30f), (40f). The reason for this is that even if one clock breaks down, the operation of the elevator can be managed by the other clock.Also, if the clock (40f) is placed only on the elevator supervisory control machine (40), This is because operation control of elevators in all banks becomes impossible due to transmission line failure, etc., and furthermore,
Special (30f) only for elevator group management controller (30)
This is because if the elevator supervisory control machine (40) is installed, the operation cannot be controlled based on the time from the elevator supervisory control machine (40).

Here, a specific explanation will be given of the training time adjustment operation of each controller of this elevator monitoring device.

In Figure 2, from the special on the building side to 0:00 on the 1st of every month.
It is assumed that a time signal (50) is emitted in synchronization with the minute time signal. In response to this time signal (50), time signal 1 (40e) of the elevator supervisory controller (40) is output, and the clock (40f) of the elevator supervisory controller (40) is reset to the time of 0:00. The advance or delay of the time will be corrected. At the same time, similar time signal signals (30g), (3], g), (34g) are sent from the I/F (40d) to each elevator group management controller (30), (31), (34
) will be sent to. Then, the time signal (30e) is output to the clock (30f) via the I/F (30d), and the clock (30f) of the elevator group management controller (30) also reaches 0:00.
It is reset at the 0 minute time, and the advance or delay of the time is corrected.

As mentioned above, the elevator monitoring device of this embodiment is
Equipped with a clock (40f) whose time is adjusted by the time signal (50) from the building side, it monitors the operating status of the elevators, and also provides a time signal (30 g) to each elevator bank.

).

That is, in the elevator monitoring device of this embodiment, the clock (40f) of the elevator monitoring and control machine (40) (elevator store viewing means) is adjusted at the same time by the time signal (50) from the building side. , when the elevator group management controller (30) (elevator group management means) is 31 (30f

Therefore, the time on the clock on the building side, the time on the poem (4of) of the elevator supervisory control machine (40), and the time on the clock (30f) of the elevator group management control machine (30) in each bank are approximately the same, and the elevator monitoring The controller (40) monitors the operation status of the elevator and sends a signal; the elevator group management controller (30) performs elevator group management; the elevator controller (20) and the drive control circuit (
] 4) The actual elevator operation control operations according to the method 4) can be performed substantially simultaneously in time. Therefore, even if the elevator operation is controlled based on the time of the clock (40f) of the elevator supervisory control machine (40), the information time displays in each elevator car substantially match. Also,
The operation status of the elevator does not differ between banks. Furthermore, the operation control of the entire elevator is matched with the control of other building equipment (for example, security, etc.).

As a result, services for elevator users such as passengers are improved, and highly reliable elevator operation can be realized.

Incidentally, in the above embodiment, a case has been described in which the time of each clock is corrected once every month, but the time of each clock may be corrected once a year, and the number of times is not limited. Furthermore, in the embodiment described in -1-, the time signal (
The time of each clock was corrected based on 50), but if the time signal (50) could not be obtained from the building side, the time signal was corrected by special training (40f) of the elevator night monitoring and control machine (40). The special training time of each bank may be corrected using the communication B. Furthermore, in the above embodiment, the time signal (
50) to adjust the time of the special training (40f) of the elevator supervisory controller (/4.0), and the time signal (30g) from this elevator supervisory controller (40).

[Effects of the Invention] As described above, the elevator monitoring device of the present invention includes an elevator monitoring means, an elevator group management means, and an elevator operation control means, and the elevator monitoring device has a clock or a predetermined time signal of the elevator monitoring means. By using a simple configuration in which the time is adjusted by the same time signal signal as the above-mentioned time signal signal, the time signal of the elevator group control means' clock is also adjusted at the same time by the time signal signal of the clock on the building side. By using this, the time on the building's clock, the time on the elevator monitoring means, and the time on the elevator group management means of each bank can be corrected to substantially match each other, and the elevator operation by the elevator monitoring means can be adjusted. Since the status monitoring operation and signal transmission operation, the elevator group management operation by the elevator group management means, and the actual elevator operation control operation by the elevator operation control means can be made to substantially coincide in time, it is possible to Service for elevator users is improved, and highly reliable elevator operation can be realized.
