Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a monitoring control system for elevators and escalators installed in a plurality of buildings.
[0002]
[Prior art]
Conventionally, monitoring and controlling a plurality of elevators at one place is well known. For example, in the same building, a main station installed in a control device of a machine room and a plurality of remote stations installed on each floor are connected by a multi-drop transmission line to transmit signals, but away from the machine room It is known that signal transmission is also performed using a fiber optic cable for a monitoring control panel for monitoring the entire building installed in a place (Japanese Patent Laid-Open No. 63-208486).
[0003]
[Problems to be solved by the invention]
By the way, all of the conventionally known elevator signal transmission devices are controlled by the elevator in the same building.
[0004]
However, depending on circumstances, there are cases where it is desired to monitor and control elevators such as elevators and escalators in other buildings from the control panels of a plurality of buildings. For example, as shown in FIG. 2, there are a department store 10, a station building 20, and a hotel building 30, each of which includes elevators 11, 21, 31 such as elevators and escalators, which are monitored and controlled by a monitoring line a and a control line b. 12, 22, and 32, and when the elevator 21 of the station building 20 is partly shared, the station building 20 from the monitoring control panel 12 of the department store 10 or the monitoring control panel 32 of the hotel building 30 in an emergency or the like. Sometimes you want to monitor and control an emergency elevator.
[0005]
In such a case, conventionally, the monitoring lines c and d for connecting the monitoring control panels 12, 22, and 32 of each of the department store 10, the station building 20, and the hotel building 30 are provided using a communication cable made of a metal cable. At the same time, it is necessary to lay control lines e and f for connecting the monitoring control panels 12 and 32 of each of the department store 10 and the hotel building 30 to the elevator 21 such as an elevator of another building (station building 20).
[0006]
However, the laying of the control lines e and f extends from the monitoring control panels 12 and 32 of each building of the department store 10 and the hotel building 30 to the elevator 21 of the station building 20 of the other building. The wiring space had to be increased.
[0007]
Accordingly, an object of the present invention is to provide a monitoring control system for elevators in a plurality of buildings that can solve the above-described problems and can greatly reduce wiring space and cost.
[0008]
[Means for Solving the Problems]
To achieve the above object, a monitoring control system for a plurality of building elevators according to the present invention monitors and controls a first elevator provided in a first building using a first monitoring line and a first control line. A second monitoring control panel and a second elevator installed in a second building different from the first building are monitored and controlled using a second monitoring line and a second control line. And a monitoring control system for a plurality of building elevators, wherein the second elevator is configured to be shared by the first building, and the first monitoring control panel and The second monitoring control panel is connected to each other by a third monitoring line and a third control line, and the first monitoring control panel passes through the second monitoring control panel, The second elevator can be controlled using the second control line.
[0009]
Since the monitoring control panel of any building can be used to monitor the elevators of other buildings via the monitoring control panel of other buildings, for example, from an emergency control panel of a department store or a hotel building, The emergency elevator can be monitored and controlled. Since this is equivalent to sharing control lines, the wiring space and cost are significantly higher than when the control lines are wired from the monitoring control panel in the building to the elevator in the other building as in the past. Reduced.
[0010]
In addition, it is preferable to use an optical fiber cable as a monitoring line and a control line which connect between the monitoring control panels of each building.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on the illustrated embodiment.
[0012]
FIG. 1 shows a monitoring control system for three elevators of a department store, a station building, and a hotel, similar to the case of FIG. 2 described above. The department store 10, the station building 20, and the hotel building 30 are each an elevator or an escalator. And the elevator 21 of the station building 20 is partially shared by the department store 10 and the hotel building 30.
[0013]
However, unlike the case of FIG. 2, in each of the department store 10, the station building 20, and the hotel building 30, the elevators 11, 21 and 31 are connected to each building by the monitoring line 1 and the control line 2 made of optical fiber cables. Connected to the monitoring control boards 12, 22, and 32, an optical fiber cable LAN (local area network) is constructed. On the other hand, the monitoring control panel 12 of the department store 10 and the monitoring control panel 22 of the station building 20 are mutually connected by the monitoring line 3 and the control line 4 made of heat-resistant optical fiber cables. The monitoring control panels 32 of the building 30 are also connected to each other by a monitoring line 5 and a control line 6 made of a heat-resistant optical fiber cable, and a disaster prevention LAN is constructed as a whole. In order to enable connection of these optical fiber cables, each of the monitoring control panels 12, 22, 32 and the elevators 11, 21, 31 has a built-in interface IF.
[0014]
Since it is configured in this manner, the elevator control units 11, 21, 21 in other buildings pass through the monitoring control panels 12, 22, 32 in other buildings in the monitoring control panels 12, 22, 32 in any building. 31 can be monitored and controlled. For example, when it is desired to monitor and control the emergency elevator of the station building 20 from the monitoring control panel 12 of the department store 10 or the hotel building 30 in an emergency, the station building 20 The monitoring control of the elevator 21 of the station building 20 can be performed via the monitoring control panel 22. This is because the control lines 1 and 2 are shared so that the control lines e and f need not be wired from the monitoring control panel of the building to the elevator of the other building as in the prior art. Space and cost are greatly reduced.
[0015]
In addition, since the monitoring control panels 12, 22, and 32 are connected by an optical fiber cable, they are not affected by electromagnetic noise as in the case of using a metal cable, and long-distance transmission by high-speed transmission processing is possible. is there.
[0016]
【The invention's effect】
In short, according to the present invention, the monitoring control panels of each building are connected to each other by a monitoring line and a control line, and the other monitoring control panel of each building passes through the monitoring control panel of another building. Since it is possible to monitor and control elevators such as elevators and escalators in buildings, for example, emergency elevators in station buildings can be monitored and controlled from a monitoring control panel in a department store or a hotel building in an emergency. Moreover, since the control lines are shared in each building, the wiring space and cost are reduced compared to the conventional case where the control lines are wired from the monitoring control panel of the building to the elevators of other buildings. Significantly reduced.
