DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator remote monitoring system for notifying a failure to a monitoring center when an elevator failure occurs and for collecting failure data relating to the failure by a failure data collection device.

[0002]

2. Description of the Related Art An elevator installed in a building is an indispensable means of transportation for residents of the building and for people entering and exiting the building. A lot of trouble occurs,
There is a risk of accidents involving human beings. For this reason,
When a failure occurs in an elevator, a quick response is required for a report to a monitoring center of a maintenance company, a recovery work by a specialist engineer, and the like.

[0003] In order to prevent the occurrence of such a failure of the elevator and to quickly recover the failure when the failure occurs, a building in which the elevator is installed is provided with a remote monitoring terminal connected to an elevator control device. This remote monitoring terminal is connected to a monitoring center of an elevator maintenance company via a telephone line. Then, the terminal monitoring device constantly captures and stores the elevator operating state data from the elevator control device, determines whether there is a failure based on the captured operating state data, and when a serious failure occurs, operates the elevator at that time. The status data is separately stored, and a fault is reported to the monitoring center via a telephone line.

[0004] On the other hand, when the monitoring center receives such a failure report, it dispatches maintenance personnel to the site so that the failure can be recovered, and at the same time, failures such as operation data at the time of failure stored in the remote monitoring terminal are stored. The data is read out via a telephone line, the cause of the failure is identified by referring to the data at the time of the failure, and the on-site recovery work is supported from behind.

Japanese Unexamined Patent Application Publication No. 4-68563, filed by the present applicant as a conventional technique, discloses that when an elevator failure is detected, the operating status and control data for a certain period of time before and after the failure is detected are stored. A method is described in which such data is read out via a communication line and confirmed in a time chart.

On the other hand, in recent years, the number of buildings that deliver a plurality of elevators to the same building has increased, and in that case, the cost is increased by sharing a single public line of a remote monitoring terminal installed to monitor each elevator. Are often used. JP-A-6-77129
In Japanese Patent Laid-Open Publication No. 1 (1999) -2003, as a method of performing data communication by transmitting data from a center device to a plurality of remote monitoring terminals sharing a public line, the order of incoming calls is set in advance for each remote monitoring terminal. A function of selecting a target terminal device from a plurality of remote monitoring terminals sharing a line by using an incoming stop setting means for stopping incoming of a remote monitoring terminal for a predetermined time from the device side is described. .
According to this method, when accessing a terminal having a lower reception order among a plurality of terminal devices sharing a line from the center device, a call termination setting is sequentially performed on a terminal higher than the target terminal, The upper-level terminal does not receive a call for a certain period of time and then makes a call again to communicate with the lower-level target terminal.If the target terminal has a lower receiving order, it is higher than that terminal It is necessary to set the incoming call stop setting for all terminals one by one.

[0007]

By the way, there are various types of elevator failures, ranging from very minor to urgent ones, such as confinement failures, which cause a great deal of trouble to passengers, such as confinement failures. Is an important failure in which a waste of one minute and one second is not allowed. When such a failure occurs at a site where a line is shared by a plurality of remote monitoring terminals, when data relating to the failure is collected from the monitoring center, the data is received from the monitoring center data collection device until the terminal reaches the terminal. Incoming call setting must be sequentially performed for the terminals with higher ranks, and each time the calling operation, the data communication, and the communication end operation are repeated for each terminal, precious time is spent during this period. there were.

An object of the present invention is to provide an elevator remote monitoring system which enables a plurality of monitoring terminals sharing a line to quickly collect operation data for investigating the cause from a monitoring terminal detecting a failure. To provide.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a remote monitoring system for an elevator according to the present invention.

FIG. 1 is a block diagram showing an embodiment of an elevator remote monitoring system according to the present invention.

Here, two elevators 1 and 2 are provided in the same building 8, and each elevator 1 and 2
2 is a car 1 connected to the other end of the main rope wound on sheaves 14 and 24 with one end connected to counterweights 13 and 23.
2 and 22 are connected, and the operation is controlled by elevator control devices 11 and 21, respectively.

The remote monitoring terminals 3 and 4 installed in the building 8
Have the same configuration, so that the remote monitoring terminal 3 will be described here as an example. Operation data reading means 31 for reading the operation data of the elevator 1 and analyzing the operation data to detect a failure of the elevator And a center communication means 33 for communicating with a remote center device via the communication line 5.
A failure data storage means 35 for reading and storing data relating to the elevator failure at that time when the elevator failure detection means 32 detects a failure from the operation data reading means 31, and a call signal from the data collection center 7 Line connection means 34 for connecting to the center communication means 33, and an incoming call for storing a time period for ignoring the call signal from the data collection center 7 for a predetermined time when the line connection means 34 detects the call signal. It comprises a time period storage unit 36 and an incoming time period changing unit 37 that changes the time period stored in the incoming time period storage unit 36 to a predetermined value when the elevator failure detecting unit 32 detects a failure.

The monitoring center 6 communicates with the remote monitoring terminals 3 and 4 in the customer building 8 via the communication line 5 and the remote monitoring terminals of elevators in other customer buildings (not shown). It has a function of making various settings for the terminals 3 and 4 and receiving alarms from the remote monitoring terminals 3 and 4.

The data collection center 7 includes a monitoring center 6
Communicates with the remote monitoring terminals 3 and 4 in the customer building 8 in the same manner as described above. When the remote monitoring terminals 3 and 4 detect a failure, the failure of the remote monitoring terminals 3 and 4 via the public line 5 The data relating to the failure stored in the data storage means 35 and 45 is read out to analyze the failure.

Here, the incoming time limit storage units 36 and 37 store
Different time periods are set in advance for each,
According to the value of the time limit, which remote monitoring terminal connects to the data collection center 7 first when accessed from the data collection center, that is, the incoming call order is determined. In the present embodiment, the value of the incoming time limit storage unit of the remote monitoring terminal 3 is 10 seconds, the value of the incoming time storage unit of the remote monitoring terminal 4 is 20 seconds, and the incoming order of the remote monitoring terminal 3 is higher. In the following description, it is assumed that the information is preset.

Normally, when the elevators 1 and 2 access the remote monitoring terminal 4 from the data collection center 7 in a normal state, when the originating process is performed from the data collection center 7, the remote monitoring terminal 3 having a higher reception order is received. And the line is connected, the data collection center 7 stores the value of the incoming time limit storage unit 36 in the remote monitoring terminal 4 so that the incoming order is temporarily lower in the remote monitoring terminal 3. Is set so that the time limit becomes 30 seconds, for example, so that the time limit becomes 30 seconds, and the communication is terminated in a state where the order of arrival is changed. Thereafter, when the calling process is performed again from the data collection center 7, the value of the reception time storage unit 36 of the remote monitoring device 3 is now 30 seconds, which is larger than the value of the reception time storage unit 46 of the remote monitoring device 4. Then, the line connection means 44 of the remote monitoring device 4 is connected first, and communication can be performed. Note that the value in the incoming time limit storage unit 36 of the remote monitoring terminal 3 is temporarily changed in order for the data collection center 7 to communicate with the remote monitoring terminal 4, and automatically changes to the initial value after a predetermined time has elapsed. 10 that was set to
It is configured to return to the value of seconds.

The elevator control devices 11, 21 are usually
It has various operation data for controlling the elevators 1 and 2, respectively, and the operation of the cars 12 and 22 is controlled by the operation data. The operation data reading means 31 and 41 constantly read the operation data stored in the elevator control devices 11 and 21, and the elevator failure detection means 32 and 42 analyze the read operation data and read the elevator 1, 2 Monitoring for failures.

Now, in a state where the remote monitoring terminal 3 is connected to the line in 10 seconds, the remote monitoring terminal 3 has a higher incoming call rank, a failure occurs in the elevator 2, and the remote monitoring terminal 4 If the detecting means 42 determines that the failure has occurred, the elevator failure detecting means 42
Creates predetermined alarm data to be transmitted to the monitoring center 6, issues a fault alarm request to the center communication unit 43, and issues a fault detection signal to the fault data storage unit 45 and the arrival time change unit 47. . The center receiving means 43, which has received the failure report request, transmits the report data to the monitoring center 6 via the line connection means 44 and the public line 5 to report that the elevator has failed. Further, upon receiving the failure detection signal from the elevator failure detection means 42, the failure data storage device 45 reads and accumulates detailed data on a failure for analyzing a failure of the elevator from the operation data reading means 41. Upon receiving the failure detection signal from the elevator failure detecting means 42, the incoming time limit changing means 47 sets the time value of the incoming time storage unit 46 to, for example, zero second which is smaller than the incoming time of the monitoring terminal having the highest priority normally. Change and then retain that value until the elevator fault is restored.

Since the monitoring center 6 has been notified that a failure has occurred in the elevator 2, a maintenance worker is dispatched to the site so that repair work for the failure can be performed.
Data collection is started from the data collection center 7 in order to read out detailed data on the failure for analyzing the failure of the elevator stored in the failure data storage means 45 of the remote monitoring terminal 4. When the transmission process from the data collection center 7 is started, a call signal is detected by both the line connection means 34 and 44 of the remote monitoring terminals 3 and 4 via the public line 5, and at this time, the incoming of the remote monitoring terminal 4 is received. Since the time limit value of the time storage unit 46 is zero seconds, the line connection means 44 of the remote monitoring terminal 4 immediately connects to the center communication means 43. When communication with the data collection center 7 is connected, the center communication unit 43 transmits the data relating to the failure stored in the failure data storage unit 45 to the data collection center 7.

As described above, according to the present embodiment, the incoming time limit changing means 37, 47, when the elevator fault detecting means 32, 42 detects the fault of the elevator, changes the value of the incoming time storage units 36, 46. Change it to a minimum,
Since the value is held while the failure continues, when a communication request is made from the data collection center 7, the line can be first connected to the remote monitoring terminal that detects the failure of the elevator.

In the present embodiment, the number of remote monitoring terminals sharing a line has been described as two. However, when the number of remote monitoring terminals sharing a line increases, two or more terminals may simultaneously fail. The possibility of detection increases. Therefore, when two or more elevator failures occur at the same time, the importance of various failures is determined in advance, and a communication function between terminals (not shown) is provided so that the priorities are determined based on the importance of each other. By comparison, it is possible to determine the order of arrival between terminals that have detected a failure.

Further, if the communication function between the monitoring terminals is used, it is possible to change the time limit for the arrival of another monitoring terminal.
In addition to shortening the arrival time of the monitoring terminal that has detected the failure of the elevator, it is also possible to change the order of arrival between the monitoring terminal and the other monitoring terminal by increasing the arrival time of the other terminal. For example, when an elevator failure is normally detected by the highest priority monitoring terminal, if the arrival time limit of the monitoring terminal is set to the smallest, for example, zero seconds, the arrival time limit of the other monitoring terminals is set to zero seconds. In addition, since the incoming call order is not the first, furthermore, usually, by changing the incoming time limit of the monitoring terminal with the highest priority to the largest value and setting the incoming order to the lowest, the monitoring terminal that has detected a failure and the incoming Are replaced, and the order of arrival of the monitoring terminal that has detected the failure can be made highest.

[0026]

According to the present invention, in a plurality of remote monitoring terminals sharing a line, the incoming call order of the remote monitoring terminal that detects the failure of the elevator is made first, so that the cause of the failure is analyzed. Data on failures can be quickly obtained.
