Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation status confirmation apparatus suitable for investigating the suitability of operation management of a group control elevator.

[0002]

2. Description of the Related Art When a plurality of elevators are installed in one building (building), group management control is performed in order to operate these elevators efficiently. When judging the suitability of this group management control, when receiving a request for reporting the operating status of the elevator from the user of the elevator, or when a complaint about the operation of the elevator occurs,
It is often necessary to investigate the operating status of each elevator. In this case, for example, as disclosed in Japanese Patent Application Laid-Open No. 2-40589, it is used in an elevator operation diagram that changes with time, or an elevator arrives after a hall call is registered and a hall call is issued. Means such as measuring the waiting time before disappearing are used. Then, it is determined whether or not the car is functionally traveling as planned by observing the change in the mutual position interval of the elevators from the drawn operation diagram of the elevators. Such a conventional operation status confirmation device will be described with reference to FIG.

FIG. 5 is a block diagram of a conventional elevator operation status confirmation device. In the figure, 1 and 2 are elevator control devices of two elevators installed in the same building, which communicate with each other and operate a car by group management control. Each elevator control device is composed of a microcomputer, and has a memory for recording various data regarding the operation status of the controlled elevator, that is, operation data. 10 and 20 are operation status recording devices for recording the operation status of the elevator, which are operation data collection units 11 and 21, operation data storage units 12 and 22, respectively.
It is composed of communication devices 13 and 23. The operation data collection units 11 and 21 provide operation data necessary for drawing a preset operation diagram from the elevator control devices 1 and 2 for a predetermined time from the time when the preset time comes. It has a function of collecting and storing in the operation data storage units 12 and 22. The operation data storage units 12 and 22 store the data collected by the operation data collection units 11 and 21 in the memory according to the change of time. Communication device 1
Reference numerals 3 and 23 have a communication function for performing communication between the operation status recording devices 10 and 20 and the remote communication device 3, and synchronize the time managed by the operation status recording devices 10 and 20,
The data for creating an operation diagram stored in the operation data storage units 12, 22 is sent to the monitoring center 6 via the remote communication devices 3, 4.
To the display device 5 inside. 3 and 4 are telecommunication devices,
Here, the building in which the elevator is installed and the monitoring center 6 perform remote communication. A display device 5 has a function of displaying the operation data recorded in the operation status recording device as an operation diagram on the screen and setting a time at which the operation status recording unit 10 and 20 should start recording the operation status. Then, it is provided in the monitoring center 6.

Now, the operation status recording devices 10 and 20 from the display device 5 of the monitoring center 6 via the remote communication devices 3 and 4 in advance.
It is assumed that the date and time at which you want to start recording operation status is set. At the set date and time, the operation data collection units 11 and 21 periodically collect operation data necessary for creating a preset operation diagram from the elevator control devices 1 and 2, and store the operation data in the operation data storage unit. To go. The collection of the operation data of the operation data collection units 11 and 21 ends the process when a predetermined time set in advance elapses.

At this time, the operation data collection units 11 and 21 always collect the operation data in the memories of the operation data storage units 12 and 22 in a range corresponding to a certain time width.
When the set date and time is reached, operation data is collected until a predetermined time has elapsed from that point, whereby the set date and time is set at the center of the time range to be recorded, and the operation status is recorded before and after the set date and time. It is also possible.

The controller of the monitoring center confirms that a predetermined time has passed from the set date and time, and then displays the operation data storage unit 1 via the remote communication devices 3 and 4 on the display device 5.
The operation data stored in Nos. 2 and 22 are read, an operation diagram is drawn, and displayed on the screen. On the display screen of the display device 5, the elevator 1 for a predetermined time from the set date and time,
The operation diagram showing the transition of the two cars and each car call,
Hall calls are displayed in chronological order, so that it is possible to grasp the service status of the group-controlled elevators, such as changes in the mutual position intervals of the elevators and waiting times for the arrival of cars for hall calls.

[0007]

By the way, the most noticeable feature of the operation of the elevator of group management control is that the allocation of the hall call of the floor pushed at the landing is registered in the elevator that seems to arrive most easily. , After that, when it is determined that the elevator cannot answer the call, the hall call on the floor is promptly changed to another elevator to prevent the long wait that causes discomfort to users. It is a thing. Therefore, in order to confirm the important function of group management control, it is desirable to obtain an operation diagram and a time chart of related data when the operation of changing the allocation of hall calls is performed.

However, in the case where the operation status is recorded within a predetermined time from the preset operation recording start date and time as in the above-mentioned prior art, a special operation of changing the allocation of hall calls is not always performed. Not necessarily
Also, if the operation record start date and time is mistakenly set to a time zone when the elevator hardly moves, it will not be possible to catch the hall call assignment change, and the operation data collected will be wasted. There was such a problem.

An object of the present invention is to provide an elevator operation status confirmation device capable of reliably catching a hall call assignment change operation.

[0010]

In order to achieve the above object, the present invention provides an operation status recording device for recording the operation status of an elevator according to a signal output from an elevator control device, and the operation status recording device. In an elevator operation status confirmation device equipped with a display device capable of displaying the operation status recorded in (1) as an operation diagram, it is detected that the hall call allocation has been changed based on the record of the operation status recording device. When the detection means and the detection of the hall call assignment change by the detection means, the operation status related to a predetermined time before and after the detection time is selected as specific data from the record of the operation status recording device. The selection means and the output means for displaying the operation diagram corresponding to the specific data selected by the selection means on the display device.

[0011]

The operation status recording device reads the operation status of the elevator from the elevator control device, detects the hall call assignment change by the detection means, and selects the operation status for a predetermined time before and after the detection time as the specific data by the selection means. The specific data selected and output by the output means is output to the display device. Since the display device draws and displays an operation diagram for a predetermined time before and after the change of the hall call assignment based on the specific data, it is possible to confirm the history of the change of the hall call assignment and the related data. By doing so, the operation status of the group control elevator can be surely grasped.

[0012]

The present invention will be described below with reference to the illustrated embodiments.

FIG. 1 is a block diagram of an elevator operation status confirmation apparatus according to an embodiment of the present invention. In FIG. 1, parts that are the same as or equivalent to the parts shown in FIG. Numerals 14 and 24 are call assignment change detection units, which constantly monitor the operation data of the elevator control devices 1 and 2 collected by the operation data collection units 11 and 21 to detect that a hall call assignment change has occurred, and communicate with each other. A function of notifying another operation status recording device 10 or 20 via the devices 13 and 23 that a hall call allocation change has occurred, and giving an operation data collection start command to the operation data collection units 11 and 21. Have. Fifteen, two
5 is necessary to draw an operation diagram before and after the time when the hall call allocation is changed and a time chart of various data related to it from the operation data stored in the operation data storage units 12 and 22. It is a specific data selection unit that selects specific data. Reference numerals 16 and 26 are specific data output sections that output the specific data selected by the specific data selection sections 15 and 25 to the specific data storage sections 17 and 27. 1
Reference numerals 7 and 27 are specific data storage units for storing the specific data output by the specific data output units 16 and 26.

FIG. 2 is data showing the allocation state of hall calls. "1" is set in the floor part where the hall call is registered, the car arrives at the floor and the call is erased. Holds up to. Since such data is exchanged by communication between the elevator control devices 1 and 2, it is possible to grasp the allocation status of the hall calls to each other.

FIG. 3 shows the call assignment change detection units 14 and 24.
It is a flowchart showing the processing content of.

FIG. 4 is a part of an operation diagram in which the display 5 displays the hall call assignment change operation detected in this embodiment.

The operation will be described below with reference to these figures.

The operation data collection units 11 and 21 always collect the operation data of the elevators 1 and 2 and store the operation data in the memories of the operation data storage units 12 and 22 in a range corresponding to a certain time width. The operation data includes data representing the hall call allocation state as shown in FIG.

Now, in the two elevators in which the first and second units are performing group management control of the eighth floor, the first hall call in the upward (UP) direction on the second floor was waiting on the first floor. Although it was assigned to, the car on the first floor could not answer the hall call on the second floor because the passengers boarding the first floor from the first floor were full, and the car call was registered after passing the second floor. It is assumed that the hall call on the second floor has been reassigned to Unit 2 because it has headed for.

Here, the call assignment change detection unit 1 of the first machine
4 will be described with reference to the flowchart of FIG. 3 and the operation diagram of FIG.

The call assignment change detection unit 14 checks whether the traveling direction of the car is an up (UP) direction or a down (DN) direction according to the operation data, and if it is the UP direction, the process proceeds to step S21, and from the DN direction to step S22. It branches (step S1). Since Unit 1 is in the UP direction here, the process proceeds to step S21.

Next, the hall call assignment state data is checked to see if the hall call data in the UP direction has a floor changed from "1" to "0" (step S21). At time t in the operation diagram of FIG. 5, the hall call allocation is changed, and the hall call in the UP direction on the second floor of Unit 1 has been cancelled. The change of 0 "is detected and the process proceeds to step S31.

Next, the floor on which the car is sitting is compared with the floor on which the change from "1" to "0" is detected,
If it is on the same floor, it is because the car answers the hall call and arrives at that floor, and the hall call is deleted. This is not due to the change of the hall call assignment, so return to step S1 and arrive at the car. If the floor is not the same as the floor, the process proceeds to step S41 (step S31). At this point, the car is traveling and has not yet arrived at the floor, so the flow proceeds to step S41.

Next, the data of the hall call in the UP direction of the other machine, that is, the second machine is checked, and "0" to "1" are checked.
Check whether there is a changed floor (step S4)
1). The hall call in the UP direction on the 2nd floor that was originally registered in Unit 1 was canceled, and the hall call in the UP direction on the 2nd floor of Unit 2 was registered instead.
Detected a change of "0" from the floor and the "0" of Unit 2
Since the floor from which the change of "1" is detected coincides with the floor, it is considered that the hall call allocation change has occurred, and the process proceeds to step S51.

In step S51, the call assignment change detection unit 14 notifies the call assignment change detection unit 24 on the No. 2 side via the communication devices 13 and 23 that the hall call assignment change has occurred, and the operation is performed. The data collection unit 11 is instructed to start recording the operation status. The call assignment change detection unit 24 on the No. 2 side, which has received the fact that the hall call assignment has been changed via the communication device, similarly issues a command to the operation data collection unit 21 to start recording the operation status. give. In this way, the operation status recording timings of Units 1 and 2 are synchronized.

Upon receipt of the command, the operation data collection units 11 and 21 secure the data stored in the memories of the operation data storage units 12 and 22 within a range corresponding to a certain width, and The operation data is collected and stored in the memories of the operation data storage units 12 and 22 until a predetermined time elapses from the time when the command is received.

After detecting the hall call allocation change,
When a predetermined time set in advance elapses, the specific data selection units 15 and 25 select the operation lines before and after the change of the hall call allocation is detected from the operation data stored in the operation data storage units 12 and 22. Specific data necessary for drawing a time chart of a drawing and various data related thereto are selected and stored in the specific data storage units 17 and 27. When the selection of the specific data by the specific data selection units 15 and 25 and the storage of the specific data in the specific data storage units 17 and 27 are completed, the operation data collection units 11 and 21 again output the operation data with a certain width. The operation of storing in the memories 12 and 22 is repeated.

The specific data stored in the specific data storage units 17 and 27 are read out through the remote communication devices 3 and 4 by operating the display device 5 of the monitoring center 6, and the operation as shown in FIG. It is displayed as a diagram. At this time, according to the operation diagram, various data related to the change of the allocation of hall calls, for example, the data showing the weight of the car in this case, is also displayed as a time chart, so that the phenomenon that occurred can be accurately identified. You will be able to understand.

Even when the traveling direction of the car is the descending (DN) direction, steps S22, S32, S42 and S are similarly performed.
52.

As described above, according to the present embodiment, by providing the call assignment change detecting units 14 and 24, the special operation of the group management control such as the hall call assignment change is surely caught, and the operation before and after that is performed. It is possible to obtain a diagram and use it to improve the function of group management control.

[0031]

According to the present invention, the detection means for detecting the occurrence of the hall call assignment change and the detection means for detecting the occurrence of the hall call assignment change are detected at the time of the detection. Assignment of hall calls is provided by providing selection means for selecting operation statuses relating to a predetermined time before and after as specific data and output means for outputting an operation diagram corresponding to the specific data selected by the selection means to a display device. It is possible to reliably capture a special operation of the group management control called a change, obtain an operation diagram before and after that, and use it for investigating the function of the group management control and improving the function of the group management control.
