Description

[Detailed Description of the Invention] [Technical Field of the Invention] An elevator in which the same platform lantern (hereinafter referred to as lantern) serves as a forecast display, an arrival forecast display, and a departure display according to the present invention, thereby improving service to passengers. This invention relates to a display control method.

[Technical Background of the Invention] Conventionally, elevator display control has been performed as follows. In other words, from among multiple elevators installed and operating on multiple floors, the optimal response elevator car is assigned to a common hall call, and the assigned car lights up the hall lantern and displays the forecast. Do the following. Then, when the forecast car begins to slow down, the lantern will flash to guide customers.
Display the arrival forecast. Furthermore, even when the passenger arrives at the landing only by car call, the arrival forecast is displayed a certain period of time (several seconds) before the door is opened.

On the other hand, on standard floors, etc., the first car guides passengers by flashing lanterns, and during certain times when there is a high demand for elevators, such as when going to work, the departure interval is controlled, and after being designated as the first car, a predetermined It is controlled to depart after a certain amount of time has elapsed.

[Problems with background technology]

However, in such a case, after the standard floor up direction call is registered and the forecast car is displayed, if the car arrives at the standard floor earlier than the forecast car due to first arrival, pullback first arrival, etc. The car receives the advance command and guides passengers by blinking the lantern for the departure interval time. After that, when the car that is displaying the forecast decelerates to the standard floor, the arrival forecast will be displayed, so the lanterns of the two elevators will flash in addition to the above-mentioned car. It is not possible to determine which car will leave first.

That is, as shown in FIG. 1a, the A car is assigned to the upbound call that occurs on the Lb floor, and the service reservation for the Lb floor is indicated by lighting up the lantern. However, as shown in Figure b, if Car B arrives earlier than the forecast car A due to being the first to arrive at the car call or the first to be pulled back, Car B will receive the first order command and perform the first display (flashing lantern). . During this time, when Car A arrives in response to the above-mentioned landing call, an arrival forecast display (flashing lanterns) is performed several seconds before arrival, so both Cars A and B flash lanterns as shown in c in the same figure. There is a problem in that passengers arriving at the boarding point later cannot tell which car is the first car.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to provide even when the forecasting basket is about to arrive at the hole where the starting basket is already located.
To provide a display control method for an elevator, which can clearly display which car is the first car at a landing, avoid confusion among passengers waiting at the landing, smoothly control departure intervals, and greatly improve service to passengers. There is a particular thing.

[Summary of the invention]

In order to achieve the above object, the present invention allocates an optimal response car to a call that has occurred from among a plurality of elevators installed on a plurality of floors and operated, and two allocated cars are assigned to a car. A first device that displays a forecast at the landing by lighting up a lantern provided at each landing, and also displays a forecast of arrival at the landing by flashing the lantern a certain time before the assigned car starts decelerating and arrives at the landing. and a second device that selects the first car at at least one landing during a certain time period and displays the first car at the landing by blinking the lantern of the selected car. If a car other than the predicted car in the same direction at the landing is flashing its lantern in response to an advance command,
When the predicted car starts to decelerate, the arrival forecast is not displayed by flashing lanterns, but the door is opened while the forecast is displayed by lighting the lanterns, and the flashing lanterns are displayed after the preceding car departs. Features.

[Embodiments of the invention]

Hereinafter, an elevator display control method according to the present invention will be explained with reference to the drawings. Figure 1 d is
3 shows a lantern motion display form according to the present invention. In other words, as explained in the prior art, when the forecast basket arrives at the standard floor with the forecast incorrect,
The first-arriving car is designated as the first to arrive and guides passengers with a flashing lantern, while the missed prediction car has its door open with its lantern lit to guide passengers. Then, after the preceding car departs from the standard floor, the forecasting car receives the preceding command and flashes its lantern, so that it will depart from the standard floor after the departure interval control time has elapsed.

FIG. 2 shows an example of a system configuration for realizing the above display control. In Figure 2,
10 is a hall registration circuit. When a hall call is registered, <
11> bit is input, the arithmetic unit 23 in the group management control device 25 searches for this, selects the most suitable response car from among the eight cars, and sends it to the sub-car call registration circuit 1.
Allocate and output to 3A to 13H. At this time, the lantern at that boarding point simultaneously displays a forecast (the lantern lights up). At the same time, when the HCT<10> bit is set and the allocated car decelerates in response to the landing, the car position signal from the selectors 14A to 14H clears the hall call registration, and the HCT<10> bit is set.
11>Reset the bit as well. At this time, the lantern will blink and continue until the door is closed. Also,
When the allocated car opens its door and completes its service to the landing, a selector car position signal is obtained, the lantern is erased, and at the same time the allocated bit HCT<10> bit is also reset.

On the other hand, 11A to 11H are car call registration circuits, and car call registration buttons 15A to 1 for each floor on the in-car operation panel
When 5H is pressed, the car call is registered, the bit corresponding to the HCT number is set, and when the car finishes servicing the floor on which the car was registered, the car position signal is obtained, the registration is erased, and the call corresponds to the HCT number. The bits are also reset. At this time, the lantern will blink until the door closes.

In addition, 12A to 12H are car status buffers, including the car position from selectors 14A to 14H, and relay contacts 16A to 16A, which close when the door is opened.
16H, relay contact 17A that closes when there is no direction
~17H, contacts 18A~18H that close while driving,
Signals such as contacts 19A to 19H, which close in the car direction UP, contacts 20A to 20H, which close in the car direction DN, and contacts of a limit switch installed at the bottom of the car, which closes when the car is full, are input, and are input to the CCT 22 for each car as a car status signal. be done. In the above explanation, a case where a building with 10 floors is serviced by a group of 8 units is described, and the units provided for each unit are indicated by A to H. Further, arrow lines in the figure indicate a plurality of signal lines.

FIG. 3 shows an example of the configuration of the lantern operation command circuit. In the figure, a relay SC35 is provided for each car, and is energized by receiving a command from the preceding command output device 23 through the preceding relay due driver. The reset is also performed upon receiving a command from the advance command output device 23. When relay SC35 turns N, the lantern starts blinking and the door opens. When relay SC35 becomes FF, the door closes and the flashing of the lantern ends and disappears at the same time as the door closes. The relay SC35 becomes FF when the departure interval time (10 to 15 seconds) has elapsed after N, or when the elevator becomes full, and when it becomes FF, the elevator departs. In the figure, 39 is a dummy resistor for the flicker unit, and 40 is a flow selector, which reduces the elevator's ascent and descent to about 1/100. There is a segment for each. moreover,
32A to 32Z are diodes for preventing wraparound.

In FIG. 3, when a current landing call is registered, the allocation output for that floor is sent from the allocation output device 23 in the group management control device 25, and the lantern corresponding to each floor of the car is sent via the allocated floor decoding circuit 30. One of 31A to 31Z lights up. In the assigned car, when the advancer (forward platform) that guides the elevator to the assigned floor arrives, the contact 33 of the deceleration command relay SLD (not shown) closes, and if the position is not the standard floor, the contact 34 of the standard floor relay HF (not shown) closes. Since it is Fritzker unit 36
operates and the car direction is UP, relay contact 37
will close and the lantern in the UP direction will blink. The deceleration command relay SLD is held after the advancer in the floor selector 40 arrives at the called floor until the door is closed. In addition, the reference floor relay HF is N until the advancer of the floor selector 40 leaves after arriving at the reference floor.
are doing. When voltage is applied to IN, the flicker unit 36 sends out a flickering output to the UT side, causing the lantern to flicker. In this figure, the lantern 31B is blinking. However, when the car decelerates to the standard floor, the relay contact 34 opens, so unless this car receives the advance command and the contact 35 of the advance relay SC closes, the flicker unit 36 will not operate, so the lantern will remain lit and the door will open. will open.

In this way, the optimal response car is assigned to a hall call issued from among multiple (8) elevators installed and operated on multiple floors (10th floor).
In addition, this assigned car lights up the lantern provided for each car to display the forecast at the landing, and also lights up the lantern provided for each car and displays the forecast at the landing by flashing the lantern for a certain period of time (several seconds) before the assigned car starts decelerating and arrives at the landing. a first device that displays an arrival forecast at a certain time, and a second device that selects a first car at at least one landing (reference floor) during a certain time period and displays the first car at the landing by flashing the lantern of the selected car. In an elevator display control device consisting of a device, if a car other than a predicted car in the same direction at a landing on the same floor is flashing a lantern in response to an advance command, the predicted car will slow down. At the start of the car, the arrival forecast is not displayed by flashing lanterns, but the door is opened with the forecast displayed by lighting the lanterns, and after the first car departs, the flashing lanterns are displayed.

Therefore, the same lantern can be used to display "forecast", "arrival forecast", and "starter", so if you go to a hole where the starting car is already flashing the lantern,
Even when a forecast car is about to arrive, it is clearly displayed to passengers who arrive later which car is the first car, so passengers can be guided without confusion, and the departure interval can be controlled smoothly. can significantly improve services.

It should be noted that the present invention is not limited to the above embodiments, but can also be implemented as follows.

〔Effect of the invention〕

As explained above, according to the present invention, when a forecast car is about to arrive at a hole where the starting car is already flashing its lantern, the service reservation is made without displaying the arrival forecast (blinking lantern), which is normally done. Open the door with the display (lantern lit),
After the first car has departed, the first car is given priority over other cars and the first car is displayed (flashing lanterns) to guide passengers, so passengers who arrive later can clearly see which car is the first car. It is possible to provide an extremely reliable elevator display control method that can guide passengers without confusion, smoothly control departure intervals, and greatly improve service to passengers.
