DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator remote monitoring device in which a number of elevators are controlled by a single monitoring center.

[0002]

2. Description of the Related Art Elevators such as elevators and escalators (hereinafter referred to as elevators) not only cause a great deal of inconvenience to a large number of people but also may cause personal injury if a failure occurs that hinders their operation. . For this reason, a monitoring center device for monitoring the operating states of a large number of elevators collectively is provided, and an elevator monitoring device for monitoring an elevator in a building (building) is provided in, for example, one building (building). When a failure occurs, a means is reported to the monitoring center device via the elevator monitoring device, and a maintenance staff of a sales office managing the failure-generating elevator in accordance with an instruction of the monitoring center device performs processing of the elevator.

[0003] In addition, means for collecting desired operation status data of the elevator from the monitoring center device via the elevator monitoring device as necessary and checking the elevator is also employed. Such an elevator remote monitoring device is proposed in, for example, Japanese Patent Application Laid-Open No. 2-121095.

[0004] The above-mentioned elevator has a function of detecting an abnormality that has occurred in itself, and has a function of detecting an earthquake, wind and flood damage, fire,
If the operation becomes dangerous due to an external event such as a power failure, the operation is automatically stopped, and the operation is restarted when the danger disappears. The elevator monitoring device collects the operation status data of the elevator, and when the operation is stopped as described above, immediately reports this to the monitoring center device. To send the subsequent operation status data. In this case, the monitoring center device creates information from each elevator monitoring device in a list for each office at regular time intervals, and transmits the list to each office by facsimile. The sales office refers to this list and dispatches a maintenance person to the elevator in the operation stop state to perform predetermined processing.

[0005]

By the way, when an earthquake, storm and flood damage, fire, power outage, etc. occur in a wide area, a large number of elevator monitoring devices are scattered to report to the monitoring center device, and data of operation status is concentrated. Therefore, in the monitoring center apparatus, it is necessary to create a list by classifying these alarms and transmitted information by business office. However, because of the large number of alarms and transmissions, there is a problem that it takes a lot of trouble and time to categorize the business offices, and it is difficult to take prompt measures.

Further, since the alerting and transmission are concentrated as described above, the monitoring center device calls the elevator monitoring device by telephone so as to transmit the operation status data to each elevator monitoring device (to execute the status confirmation work). Even if an attempt is made to give an instruction, there is a high probability that the line is blocked and communication is impossible, making it difficult to quickly grasp the situation with the monitoring center device.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems in the prior art, and to greatly reduce the processing of the monitoring center device for the alert that is concentrated in a short period of time and the task of confirming the state in which the alert has occurred. Another object of the present invention is to provide a remote monitoring device for an elevator capable of more quickly grasping the state.

[0008]

Next, the operation of this embodiment will be described with reference to the flowcharts shown in FIGS. Now, assume that an earthquake has occurred in a large area. This earthquake is detected by seismometers in each building where the elevator is installed. If the seismic intensity of the earthquake is equal to or greater than a predetermined value, the elevator stops on the nearest floor with the door open, and the elevator monitoring device notifies the monitoring center device 1 of this state. This alert is output from each elevator monitoring device in the earthquake detection area. The operator of the monitoring center device 1 knows that an earthquake has occurred in a certain area based on the concentration of the alarms or the breaking news of the news media. Therefore, the operator stops receiving the alert at the monitoring center device 1 and inputs an emergency state monitoring command to the monitoring center device 1 (procedure S ₁ shown in FIG. 3).
At the same time, the user inputs the code of the regional monitoring device which is considered to be related to the earthquake (step S ₂ ). The input of this code may be performed by inputting the minimum code and the maximum code among the codes of the relevant area monitoring device, or a code of a predetermined area may be used. The input code is given a code n indicating its order.

The monitoring center device 1 is the code n to "1" (Step S _3), and automatic dialing to the first local monitoring apparatus (Step S _4), the telephone line is connected to output the regional monitoring command (Step S _5), waits for the end of transmission of the command (Step S _6). When the transmission is finished Shi Danto the telephone line (Step S _7), it determines whether to send a command to all regions monitoring device to be commanded (Step S _8). This determination is made by comparing the code of the current area monitor with the code of the final area monitor. If the transmission to all the area monitoring devices is not completed, “1” is added to the code n to designate the code of the next area monitoring apparatus (step S).
_9), the process returns to step S _4. Processing is determined that outputs a command to all local monitoring apparatus to be commanded in Step S ₈ is completed.

[0016] The procedure S ₁₀ in FIG. 3 the monitoring center device 1
The normal monitoring processing procedure is described below, but since these processings are well known, description thereof will be omitted.

On the other hand, each area monitoring device determines whether or not it has received an area monitoring command from the monitoring center device 1 (procedure S ₂₀ shown in FIG. 4). Is set to “1” (step S ₂₁ ), which indicates the order (preliminarily set, for example, from 1 to n).
And automatic dialing to the first elevator monitoring apparatus (Step S _22), the telephone line is connected, and commanded to transmit a specific operational state data that the elevator monitoring apparatus stores (Step S _23), waiting to be transmitted (Step S _24), stores it in the storage unit (Step S _25), and disconnects the telephone line (Step S _26).

Next, local monitoring apparatus determines whether to send a command to all of the elevator monitoring device under management (Step S _27), then the monitoring center device if transmitted incomplete 1
Regional monitoring command a predetermined time after it is determined whether elapsed from (Step S _28). If the predetermined time has not elapsed, “1” is added to the code n (step S ₂₉ ), and the next step S ₂₂
Return to the processing of. Here, the judgment of the predetermined time in Step S _28, if for any reason in time-consuming data collection local monitoring apparatus, delays the list of the monitoring center device 1, the dispatch of appropriate maintenance personnel This is because it is inhibited.

[0019] When the transmission of all the elevator monitoring apparatus in step S ₂₇ is judged to be complete, or when it is determined that the predetermined time has elapsed in step S _28, local monitoring device automatically dialing to the monitoring center device 1 (Step S _30), the telephone line is connected, and ends it until the collected data to transmit to the monitoring center device 1 (Step S ₃₁₎ process.

When the monitoring center device 30 confirms that all on-site processes for a disaster (earthquake or the like) have been completed, it outputs a command to cancel the monitoring of the disaster to each of the regional monitoring devices and returns to a normal state. Return.

As described above, in this embodiment, all the elevator monitoring devices are grouped for each predetermined region, and each group is provided with a region monitoring device for managing the elevator monitoring devices of the group. Only the command to transmit specific operation status data to the monitoring device is output, and the specific operation status data of each elevator monitoring device is collected by the regional monitoring device. The apparatus can obtain specific operation state data compiled for each area, and the operator can immediately create a list without any trouble or time. or,
Compared to the conventional method in which the operation status data is transmitted from the monitoring center device to the elevator monitoring device, in the present embodiment, the transmission command is issued only to the area monitoring device, so that even if the telephone line is congested, the call can be made. The probability of possibility is significantly increased.
