JPH04116075A - Platform announcing device for elevator - Google Patents

Abstract

PURPOSE:To rapidly guide a passenger to a service elevator by mounting an announcing device to an elevator platform and announcing a service elevator responding to an elevator platform before a platform call is registered by the announcing device. CONSTITUTION:Position information on elevators 1-3 is outputted to a service zone deciding device 4. The service zone deciding device 4 computes signals for the elevators l-3 to decide a service zone. When a platform call at the zone is generated, a corresponding elevator responds to a service. An output from the service zone deciding device 4 is inputted to platform information announcing devices 5-7. The platform information announcing device inputs a signal for first floor - third floor to a No.1 elevator. In which case, contactors normally-opening contacts A1-A3 for a service zone command are closed, circuits of contacts P-A1-L1-N, contacts P-A2-L2-N, and contacts P-A3-L3-N are formed, and platform announcing devices L1-L3 for first floor - third floor effect announcement to elevator platforms at first floor - third floor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a notification device installed at an elevator landing.

[Conventional technology]

For example, as described in Japanese Patent Application Laid-Open No. 60-31487, when multiple elevators arrive at a landing, the conventional device selects the car whose car call is automatically registered and distinguishes it from other cars. The notification was supposed to guide waiting passengers to the car whose car call was registered, making it easier for the waiting passengers to board the car.

[Problem to be solved by the invention]

The above conventional technology is effective when multiple elevators arrive at a landing, but generally the waiting elevators are dispersed in order to provide efficient service, and in that case, the waiting elevators are scattered to provide efficient service. There was a problem with the service provided to customers as there was no consideration given to notifications.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an elevator hall notification device that can promptly guide passengers to a service elevator.

[Means to solve the problem]

The purpose of the above is that when a button on a landing is operated, a landing call for that floor is registered, and in a system in which one of a plurality of cars serves the call, a notification device is installed at the landing, and this notification is provided. This is achieved by notifying the service elevator that will respond to the landing before the above-mentioned landing call is registered by the device.6 [Operation] Since the present invention is configured as described above, the elevator position information is transmitted to each elevator. Detects the position and outputs the information to the service zone determination device. The service zone determination device selects the elevator that can most efficiently service the call at the landing based on the input from the elevator position information, assigns it to each elevator, and outputs the assigned floor to the notification device of each elevator. do.

Next, the notification device inputs the signal from the service zone determination device and displays the floor for which the notification device is responsible at the landing. Therefore, passengers at the platform can determine which elevator will serve them before they press the button.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the elevator platform notification device of the present invention will be described below with reference to FIGS. 1 to 4.

Fig. 1 is a block diagram showing an embodiment of the elevator landing notification device of the present invention, Fig. 2 is an external view of the landing, and Fig. 3 shows the zones where &1 to &3 elevators service the landing calls. 4 are circuit diagrams showing the operation of the landing notification device.

In the figure, 1 to 3 are elevator position information, and a signal corresponding to the waiting position of the elevator is output to the service zone determining device 4. The service zone determining device 4 inputs the position signals of the elevators 1 to 3, determines which elevator is to serve a hall call on each floor, and outputs it to the landing notification devices 5 to 7. Reference numerals 5 to 7 indicate platform notification devices, which operate the platform notification devices of the zones to be serviced by signals from the service zone determining device W4. HLUI-3 is the upward platform alarm for Isao 1-3 elevators, HLD1-3 is the downward platform alarm for &1-3 elevators, HUP is the upward platform call button,
HDN is the call button for the downward direction of the landing, P and N are the DC power terminals, A1-A10 are the normally open contacts of the service zone command contactors on the 1st to 10th floors, and the receivers are energized according to the service zone they have. . L1 to LIO are notification devices for the landing area and indicate the 1st to 10th floors, respectively.

Next, the operation of this embodiment will be explained. To make the explanation easier to understand, the number of floors in the building is 10.

The number of elevators is 3, and the Demon 1 elevator is on the 1st floor.
It is assumed that the &2 elevator is waiting at the 5th floor and the -3 elevator is waiting at the 9N.

From FIG. 1, the position information of elevators 1 to 3 indicates that the N11l elevator is on the 1st floor, the N112 elevator is on the 5th floor, and the N113 elevator is on the 9th floor, and these are output to the service zone determining device 4, respectively. The service zone determination device 4 calculates the signals of the elevators 1 to 3 and determines the service zone. FIG. 3 shows the determined service zone. NfL
l Elevators are from 1st floor to 3rd floor, &2 elevators are from 4th floor to 6th floor.
The 7th to 10th floors of the 7th to 10th floors of the elevators are reserved, and when a platform call for that zone occurs, the corresponding elevator responds to the service. The output from the service zone determination device 4 is input to the platform notification devices 5 to 7 7
Each platform notification device is N (11 elevators are from the 1st floor)
The signals for the 3rd floor, the 4th to 6th floors for the Nct2 elevator, and the 7th to 10th floors for the N113 elevator are input. Explaining with reference to FIG. 4, since the service zone of the Nal elevator is from the 1st floor to the 3rd floor, the normally open contacts of the A1-A3 service zone command contactors are closed, P-Al-Ll-N, P-A
2-L2-N, P-A3-L3-N circuits are formed,
The notification devices for the landings L1 to L3 on the 1st to 3rd floors notify the landings on the 1st to 3rd floors. Similarly, &2 and &3 elevators also notify the landings on the 4th to 6th floors and the 7th to 10th floors, respectively. An example of the notification device is the HL U shown in Figure 2.
These are the landing alarm for the upper direction of the 1-3 l1kil-3 elevators, and the landing alarm for the lower direction of the &1-3 elevators of HLD1-3.

On the 1st to 3rd floors of the landing, the Nnl elevator is in charge, so the upper landing alarm of the &1 elevator in HLtJl and the lower landing alarm of the 1st elevator in HLDl notify the landing.6. The 4th to 6th floors are HLU
2 and HLD2 will notify, and HLU3 and HLD3 will notify from the 7th to 10th floors.

As explained above, according to the present embodiment, the service elevator can be identified before the hall call is registered, so the customer can be guided to the service elevator promptly, and the service to the customer can be improved.

〔Effect of the invention〕

According to the present invention, the service elevator for a hall call can be determined before the hall call occurs, that is, at the stage when the passenger arrives at the hall, so the passenger can be smoothly guided to the service elevator, and the effect of improving service to the passenger is achieved. There is.
