DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring system for an elevator, and more particularly, to a service base in which, when an abnormal alarm is issued from an elevator control device under its jurisdiction, the operation status of the elevator that issued the alarm is reported. The present invention relates to a remote monitoring system for an elevator displayed in real time.

[0002]

2. Description of the Related Art A known elevator remote monitoring system controls the operation of a plurality of elevators installed in each building (building) and issues a plurality of alarms when one of the elevators operates abnormally. Elevator control device, a plurality of service bases under the jurisdiction of the plurality of elevator control devices, and a central monitoring center for receiving the abnormality report and notifying the service base under the control of the elevator control device that issued the report. It is composed of

[0003] In this case, in the central monitoring center,
When an abnormality report is transmitted from the elevator control device of any of the buildings (buildings), first, the name of the building where the abnormality report was performed, the abnormality, and the like are displayed on the display screen of the monitoring display device (CRT) in the center. The number of elevators in the state,
The contents of the abnormal state are displayed. Next, the person in charge of the center looks at the display contents of this display screen, checks what the current operating state of the elevator is, and then controls the elevator control device in which the abnormality alert was issued. A summary of the contents of the abnormal state is automatically transmitted by facsimile to a service base, for example, a local service center or sales office, or a telephone call is made to a person in charge. Then, at the local service center or business office, when the outline of the content of the abnormal state of the elevator is notified, a technician (maintenance staff) who can handle the abnormal state is notified of the elevator that has issued the abnormality. The elevator is dispatched to a site where there is a failure to recover the elevator from failure.

By the way, in order for a technician (maintenance staff) who has been dispatched to the site to quickly recover from the failure of the elevator, it is necessary to simply provide an overview of the abnormal state of the elevator before dispatching to the site. It is not enough to simply grasp the details of the abnormal state, for example, the current state of the failure of the elevator, the open / closed state of the door, and the like in detail.

[0005] In order to satisfy such demands, in addition to displaying the operation control state of the elevator on the display screen of the monitor and display device (CRT) of the central monitoring center, other monitor and display devices in the center have different contents. (C
A monitoring device for displaying on a display screen of (RT) has already been developed, and this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 55-156170.

The monitoring device according to the above disclosure connects the central monitoring center and the elevator control device online, and monitors the control status of each elevator on the display screen of the other monitoring display device (CRT) through this online. Then, an elevator model equivalent to an existing elevator system is displayed on a display screen of the other monitoring display device (CRT) by a combination of a set of graphic symbols or a set of character symbols, and a control state of the existing elevator is displayed. However, it is possible to grasp in detail, intuitively and in real time.

In addition, in order to satisfy the above-mentioned demand, a remote maintenance device for an elevator, in which various information in an operation control state of the elevator is reported to a service base, for example, a monitor and display device of a service center, using a telephone line. Has already been developed, and this kind of, for example,
It is disclosed in JP-A-2-95684.

The remote maintenance device for an elevator according to the above disclosure stores various information of the elevator in a predetermined memory area of a microcomputer that controls the elevator,
The various kinds of information are sent to the monitoring display device in response to a call command from a monitoring display device of a remote service center.

[0009]

However, the monitoring device disclosed in the above-mentioned disclosure (disclosed in Japanese Patent Application Laid-Open No. 55-156170) is capable of transmitting an abnormality notification from an elevator to a central monitoring center or an elevator failure notification from a customer. In this case, for example, in response to an abnormal alert that the door of the elevator does not open, the display screen of the monitoring display device of the central monitoring center displays the current position and moving direction of the elevator, the occurrence status of car calls, Only the door opening / closing state, the state of the failure is displayed, the opening and closing buttons of the operation panel in the car, the door safety as a door safety device, the door overload reversing device, the door opening / closing position, Input information on the handling of elevator users, such as the status of door stop switches and stop switches in the operation panel, and acceleration / deceleration categories during elevator travel To detailed control state etc. which of the states has a problem that does not appear.

Further, the monitoring device according to the above disclosure has a relatively long transmission period of the data sent to the monitoring display device of the central monitoring center, so that the information which changes instantaneously is
For example, when the door close button of the operation panel in the car is momentarily pressed, it does not appear as a change on the display screen of the monitoring display device. Therefore, when an error is issued to the central monitoring center due to an operation error of the elevator user or due to a failure of the elevator, merely looking at the display screen of the monitoring display device of the center indicates that the abnormal state is present. I can't grasp the details. For example, when an abnormal alarm is issued when a foreign substance is caught in a groove of a threshold of an elevator door and the door is not opened temporarily, it is possible to know details of the current state of the elevator. Because it is not possible, the service center technician (maintenance staff) must immediately go to the site where the elevator with the alarm is installed. Then, when the technician (maintenance staff) goes to the site and sees that the opening / closing operation of the elevator door is already normal, the cause of the abnormality notification is unknown, and the technician ( There is a problem that dispatch of a maintenance person) is wasted.

On the other hand, an elevator remote maintenance device (disclosed in Japanese Patent Application Laid-Open No. 2-95684) according to the above disclosure is
In the microcomputer that controls the elevator, software for editing various information and sending it to a remote service center and hardware for communicating with the service center are required. In the case where a function for sending the various information to the service center is added to the system after the delivery, a problem that communication programs must be facilitated in addition to a program for controlling the elevator. Have. Furthermore, since the various types of information are edited and sent to the service center using a microcomputer that controls the elevator, processing other than the normal elevator control processing increases, and the load on the microcomputer increases. Therefore, there is a problem that the time required for information processing becomes long and it becomes difficult to send a large amount of information at high speed to the central monitoring center in real time.

The present invention has been made to solve these problems. It is an object of the present invention to provide a method for controlling the current control state of an elevator which has issued an abnormal notification when the central monitoring center issues an abnormal notification. It is an object of the present invention to provide a remote monitoring system for an elevator, which is displayed in a detailed and immediately understandable manner.

RAM), 21 is a signal buffer, 22 is the data side ACI
A and 23 are modems, and 24 is a data side connector.

The MPU 10 controls each unit in the elevator microcomputer control unit 5, for example, controls the operation of each elevator and collects data indicating the control state of each elevator. The ROM 11 is an MPU 10
The RAM 12 stores data indicating the control state of each elevator collected by the MPU 10 in order. The ASIA 14 transmits abnormality information to the abnormality alarm device 2 when any of the elevators is abnormal. The elevator-side connector 15 causes the elevator microcomputer control unit 5 to output data of the elevator-side microcomputer bus 13. Things. The microcomputer bus 13 includes an MPU 10, a ROM 11, an RA
M12, ASIA 14, and connection connector 15 are respectively connected.

The second MPU 16 controls each part of the data collection device 9, for example, collects data indicating the control state of each elevator, reads out the data, and outputs the data to the outside. The second ROM 17 stores the second ROM 17
A program related to various controls executed by the MPU 16 is stored, and the auxiliary RAM 18 appropriately stores data collected by the second MPU 16. The signal buffer 20 transmits data from the elevator microcomputer control unit 5 only in a direction toward the data collection device 9. The DP-RAM 21 serving as a second RAM sequentially stores data indicating a control state of each elevator, and its peripheral circuit is configured to write data to the same address as that of the RAM 12. In this case, the DP-RAM 21 has two sets of bus connection terminals that can be accessed by the MPU.
11 and 16 can be accessed independently. The data-side ASIA 14 sequentially transmits data of the microcomputer bus 19 to the elevator operation status display device 8 via the modem 23 in response to a command from the elevator operation status display device 8. Microcomputer control unit 5

Here, the following operations are executed in the elevator microcomputer control unit 5 and the data collection device 9.

First, the M of the elevator microcomputer control unit 5
When the PU 10 sequentially collects various data relating to the control state of each elevator, these data are supplied to the RAM 12 via the microcomputer bus 13 on the elevator side, are sequentially stored therein, and are stored from the microcomputer bus 13 on the elevator side. It is supplied to the connector 15. Then, the data supplied to the connection connector 15 is transmitted to the data-side connection connector 24 and then input to the data collection device 9.
Is supplied to the DP-RAM 21 via the PC, and is also sequentially stored there.

In this case, DP-
The reason for providing the RAM 21 is that when the data supplied to the elevator-side microcomputer bus 13 is written to the RAM 12, the same data as the data written to the RAM 12 is copied to the DP-R so that the data collection device 9 copies the data.
Since the data can be written to the AM 21, a special process of writing the data to the data collection device 9 by the elevator control device 1 is not required, and the program processing time of the elevator microcomputer control unit 5 is not affected at all. It is because it does not give. That is, the process of writing data to the DP-RAM 21 of the data collection device 9 is performed by hard logic irrespective of the operation of the second MPU 16 of the data collection device 9, and the data written to the RAM 12 by the MPU 10 of the elevator microcomputer control unit 5 is At the same time, the data is also written to the DP-RAM 21,
Content of all data stored in AM12 and DP-RAM2
All data contents stored in 1 are always equal. on the other hand,
The data written in the DP-RAM 21 can be freely read under the control of the second MPU 16 of the data collection device 9.

Therefore, the second MPU of the data collection device 9
16 can quickly and appropriately read out the desired data from the same data as the data stored in the elevator microcomputer control unit 5 without affecting the operation of the elevator microcomputer control unit 5 as appropriate. You can do it.

Next, FIG. 3 is a flowchart for explaining the operation of the elevator operation status display device 8 and the data collection device 9.

Hereinafter, the execution operation of the elevator operation status display device 8 and the data collection device 9 will be described with reference to this flowchart.

In a normal state, the data collection device 9
Is always waiting for a line connection. In this state, an alarm report is input to the central monitoring center 3, and the central monitoring center 3 is responsible for the service base 4, which controls the elevator control device 1 (elevator) in which the abnormal report has been issued, that is, the service center or the business center. The execution operation is started when a notification to the effect that the abnormal alert has been issued is sent to the location 4.

First, in step S1, the service center or the sales office 4 operates the elevator operation status display device 8 to check the current status of the elevator having an abnormal control state (hereinafter referred to as an abnormal elevator). Then, the elevator operation status display device 8 is activated. Subsequently, in step S2, the serial number of the abnormal elevator is entered using the keyboard 8B of the elevator operation status display device 8. Next, in step S3, the elevator operation status display device 8 selects a telephone number corresponding to the entered serial number, performs an automatic dial transmission to the data collection device 9 corresponding to the telephone number, and The telephone line 6 is connected to the collection device 9. In the next step S4, the DP-RAM in which the control data of the abnormal elevator is written from the elevator operation status display device 8.
The address 21 is transmitted to the data collection device 9 via the connected telephone line 6. Subsequently, in step S5, the elevator operation state display device 8 reads, from the built-in memory, fixed data representing the elevator hoistway, car rotation, control panel, seismometer, operation panel in the car, and the like.
These fixed data are graphically displayed on the display unit (CRT) 8A.

On the other hand, on the data collection device 9 side, first, in step S20, it is determined whether or not the telephone line 6 is connected to the elevator operation status display device 8, and it is determined that the connection is established ( If the determination is YES, the process proceeds to the next step S21, and if it is determined that the connection is not established (NO), the process proceeds to the step S21.
20 is repeatedly executed. Subsequently, in step S21, the address of the DP-RAM 21 to which the abnormal elevator control data transmitted from the elevator operation status display device 8 is written is received. By the way, in order to display the instantaneous control state of the elevator continuously and smoothly on the display device, it is necessary to sample (read) the control data at intervals of about 0.1 second or less. For this reason, here, 0.
Using a timer set to 05 seconds, the control data is sampled (read) each time an interruption is made due to the arrival of the set time of the timer. Therefore, in the next step S22, it is determined whether or not the interruption by the timer has been performed. When it is determined that the interruption has been performed (YES), the process proceeds to the next step S23, and the interruption is performed. When it is determined that the operation has not been performed (NO), step S22 is repeatedly executed. Subsequently, in step S23, the abnormal elevator control data read from the DP-RAM 21 is transmitted to the elevator operation status display device 8 via the telephone line 6.

Again, on the elevator operation state display device 8 side, in step S6, the abnormal elevator control data is received. Subsequently, in step S7, the received control data is stored in a floppy disk. The storage of the control data is performed to re-display the abnormal elevator control data when necessary. Next, in step S8, the control data of the abnormal elevator, that is, the control state of the abnormal elevator is graphically displayed on the display unit (CRT) 8A so as to be superimposed on the display of the elevator model equivalent to the elevator system. . Then
In step S9, it is determined whether or not a display end request has been input from the keyboard 8B. When it is determined that the request has been input (YES), the process proceeds to the next step S10, where the request is determined. When it is determined that no input has been made (NO), the process returns to step S6. Next, in step S10, the elevator operation status display device 8 transmits an end signal to the data collection device 9 via the communication line 6. Next, in step S11, the connection of the telephone line 6 is disconnected, and finally, in step S12, the series of the processing is ended.

On the other hand, in step S24, the data collection device 9 determines whether or not the end signal transmitted from the elevator operation status display device 8 has been received, and determines that the end signal has been received. Is determined (YES), the process proceeds to the next step S25, and it is determined that the end signal has not been received (N
When O) is performed, the process returns to step S22. Next, in step S25, the connection of the telephone line 6 is disconnected, and the state returns to the line connection waiting state again.

The reading and transmission of the abnormal elevator control data are performed very finely within a short period, and the data indicating the instantaneous change in the elevator control state is also displayed on the display surface 8 of the elevator operation state display device 8.
Can be displayed.

Further, in this embodiment, the elevator operation status monitoring device 8 displays the control data of the abnormal elevator received from the data collection device 9 and stores the control data on the floppy disk. In addition, the operating state of the abnormal elevator can be reproduced at a high speed or at a slow speed, and the control state of the abnormal elevator can be accurately grasped without overlooking an instantaneous change in the control data of the abnormal elevator. .

In this embodiment, the second RAM is
It is assumed that data having the same contents as the RAM 12 of the elevator control device 1 is stored in the data collection device 9 as DP-data.
Although an example using the RAM 21 has been described, the second RAM according to the present invention is not limited to the DP-RAM 21. For example, a normal RAM is used, and two MPUs 11 and 16 are used depending on the configuration of peripheral circuits. A configuration that allows access can also be adopted.

In the description of the present embodiment, the example in which the elevator operation status display device 8 is installed at the service base 4 is described. When the control status of the elevator is abnormal, the device is brought to a site where the abnormal elevator is located, and the device is directly connected to the data collection device 9 to check the control status of the abnormal elevator. You can also

As described in detail above, according to the present invention, the second RAM in which the same storage content as the RAM of the elevator control device is stored in the elevator control device.
The service base which is responsible for the elevator (abnormal elevator) that has issued the abnormal report when the abnormal report is issued to the central monitoring center 3 is stored in the second RAM. The control data of the abnormal elevator is read out and displayed on the elevator operation status display device at the service base at short intervals in real time and together with the elevator model equivalent to the elevator system. The operator (maintenance staff) can intuitively grasp the control state of the abnormal elevator, and can reduce the time required to determine the cause of the abnormal elevator at the time of failure and the time required to recover from the failure. This has the effect.

Further, according to the present invention, the reading of the abnormal elevator control data stored in the second RAM and the transmission of the control data to the elevator operation status display device are exclusively performed by the second MPU in the data collection device. Since the MPU in the elevator control device only performs the overall control of the elevator and the collection of control data of each elevator, the MPU not only collects the control data of each elevator but also reads and transmits the control data of the abnormal elevator. Each operation can be performed very finely within a short cycle, and data indicating an instantaneous change in the control state of the elevator can be displayed on the display surface of the elevator operation state display device.
