Description

[Detailed Description of the Invention] [Description of the Technical Field] This invention operates a plurality of elevators in parallel, lights up a warning light at the landing to notify passengers, and prevents passengers from boarding cars other than those in the forecast. The present invention relates to a control device for a group control elevator that minimizes unexpected movement of a car.

[Description of prior art]

In group management control of elevators in which a plurality of elevators are controlled as a group, an elevator that responds to a hall call generated by a passenger is immediately determined. At that time, the hall lanterns installed in the halls of each elevator are turned on as forecast lights, and a chime is set to give an alert. this is,
The so-called herd management system with forecast lights has become mainstream in recent years. In buildings that employ this type of group management, landing indicators are usually not used because they can be confusing.

This method allows passengers at the landing to immediately know which elevator will respond, improving service from a psychological perspective. In addition, since passengers gather in advance near the forecast car and wait, the time required to board the car is shortened, resulting in significant advantages such as improved elevator operation efficiency. On the other hand, it is necessary to devise a method for notifying the landing area when a car arrives whose forecast light is not lit.

(1) When the final call is only for a car, the hall lantern installed above the entrance to the landing of that car will (a) blink and function as a landing light.

(b) Arrival without activation and without direction.

There are two methods. (b) Decide whether to operate the lantern in the current direction of travel or the opposite direction, start the display, decelerate and stop, open the door, and change until the door is fully closed. I can't. Therefore, even though most of the time no one gets in the car and the car becomes free after the door is closed, a car call may occur in the direction indicated by the lantern, and we will calculate the evaluation when another hall call occurs. must be carried out,
The drawback was that predictions could not be made accurately.

Regarding (b), since the car can be calculated as having no direction, it can be evaluated assuming that the car becomes a free car after the door is closed, and the evaluation calculation will be accurate. However, although the car door is open for passengers at the landing, when viewed from the landing, the home lanterns are off for both the ascending and descending directions. There were no other signs, so passengers were confused as to whether it was okay to ride or not. Furthermore, when a plurality of passengers board the car at the same time and press the destination button to register a car call, the direction of the first registered call is determined based on the relative relationship between the boarding floor and the destination floor. Passengers who registered later were sometimes forced to go in the opposite direction to their desired direction, and in extreme cases, the system was thought to be malfunctioning, often resulting in unfavorable reviews.

(2) When a car is called first, in the forecast light system, once a forecast has been made, if another car arrives first or if the forecast is changed to another car, passengers' irritation increases dramatically. Therefore, advanced control technology using high-speed, large-capacity microcomputers is required. However, no matter how devised the control method is, it is not possible to completely predict the car calls that passengers randomly generate, and car calls that occur must be answered no matter what happens. Passengers have to give priority when opening and closing the doors. Furthermore, group management operation may be stopped midway through (for example, staff may change to dedicated operation or perform inspections, etc.), and in the end, changes in car calls and forecasts cannot be completely avoided.

Among these, when a car other than the forecast car arrives first by car call, the forecast is changed to that car when it is determined that the car is likely to arrive first. This system is often unpopular because the predicted car is far away from the changed car, the car is not noticed if it is behind a passenger, and it is difficult to move when there are many passengers waiting at the boarding point.
Additionally, there was a problem in which the level of irritation increased rapidly when the original forecast basket arrived within a few seconds of changing the forecast.

Therefore, in general, even if a first-arriving car occurs, the forecast is not changed, the original forecast car is left as is, and in order to prevent passengers from boarding the first-arriving car, the first-arriving car does not turn on the hall lantern or operate the landing chime. A method is used in which only the customers who call the car are allowed to get off the train. In this case, the first car to arrive does not have any markings when viewed from the landing side, so it is difficult to tell whether it is safe to ride or not, and it is often even suspected that the car is malfunctioning.

Furthermore, car calls made by passengers boarding the first-arriving car are completely unscheduled and have a negative impact on future calls, causing long waiting times or other cars being called first.

[Purpose of the invention]

The present invention prevents passengers from boarding when an elevator whose forecast light is not illuminated reaches a landing, minimizes unexpected movement of the car, improves forecast accuracy, and prevents passengers from boarding the elevator. An object of the present invention is to provide a control device for a group management elevator that improves service for the entire elevator group while minimizing dissatisfaction.

[Summary of the invention]

The display device is equipped with an indicator light (hereinafter referred to as the boarding refusal light) in a position within the car that is easily visible to passengers at the landing, and when the last call is only for the car and the door is open, the boarding refusal lamp is turned on to prevent passengers from boarding. To prevent.

Or, they appeal to passengers not to board the car, such as saying, ``We apologize for the inconvenience, but please wait for another car.''

FIG. 3 shows a lighting circuit for a display device provided in each elevator to notify boarding refusal. PC and NC indicate the positive bus line and negative bus line of the power supply, respectively.

DNL is the lamp in the boarding indicator light in Fig. 11, UHL is the upward direction light 9, and DHL is the downward direction light 10.

UHb ₁ indicates a normally closed contact of a known upward direction determining relay UH (not shown), and UHa indicates a normally open contact. Relay UH is configured to turn on when the direction of travel of the elevator is upward, and to turn on only when the next direction of travel is upward at the last called floor.
DHa and DHb are similarly descending direction determining relays DH.
It is an auxiliary contact. When the final call is only a car call, there is no direction. When the final call is a hall call, a hall call, or a car call, the relay UH or DH in the same direction as the hall call turns on and remains on until the door is fully closed after the door is opened. Note that the subscript a indicates a normally open contact, and the subscript b indicates a normally closed contact.

WLDa ₁ and WLDb are auxiliary contacts of a known group operation relay WLD (not shown) that is turned on during group management operation and turned off when out-of-group operation is required such as failure or inspection.

INDb is a known dedicated operation relay that is turned on when the driver separates from the group and performs exclusive operation.
This is an auxiliary contact for the IND (not shown).

DCRb ₁ and DCRb ₂ are auxiliary contacts of a known door closure confirmation relay DCR that turns on when all landing doors and car doors are completely closed.

FIG. 4 shows a control circuit for a hall lantern provided for each elevator. FLK is a Fritzker relay that repeatedly turns on and off at a cycle of about 1 second when energized. 1UL to 3UL are lamps for the ascending hall lanterns 7 of the landings on the first to third floors, respectively, and 2DL to 4DL are lamps for the descending hall lanterns 8 of the second to fourth floors, respectively.

SLDb is a normally closed contact of a known deceleration command relay (not shown), and when the car advances to the point where it should start decelerating, it turns off and issues a deceleration command, and after the car stops and the door opens, it should respond next. It is configured to turn on and start when a call is received and the door is closed.
1RF to 6RF and 11RF to 16RF are diodes.

1UKa to 3UKa are normally open contacts of known ascending call assignment relays (not shown) for the 1st to 3rd floors, respectively;
Similarly, DKa to 4DKa are normally open contacts of known descending call assignment relays (not shown) for the second to fourth floors.
In a known manner, when a hall call occurs, a group management control device performs a predetermined evaluation to determine and command which elevator should respond. nUK of the corresponding floor and direction of the car that received the command, or
The nDK relay turns on, lights up the forecast light, and determines the running direction of the car by a direction selection circuit (not shown). After the car stops on that floor in that direction and the door is opened, it continues to turn on until the door is fully closed and then turns off.

When the car starts, it turns on before the actual car position by at least the distance required for deceleration depending on the speed of the car. do. After the car decelerates, it maintains the planned stop floor.

Next, the operation will be explained.

(1) When the car stops at the assigned hall call.

For example, when the car is rising, relay 3UK
When the other relay 4DK stopped in response to
Suppose that the response to is assigned. In Figure 4, As a result, the 3rd floor ascending hall lantern 3UL lights up and displays the forecast. or, The descending hall lantern 4DL on the 4th floor was also lit. The car approaches the third floor and relay 3
After XF turns on, when deceleration starts, relay SLD
is turned off, flicker relay FLK is activated by PC-SLDb-FLK-NC, and auxiliary contact FLKb opens and closes approximately every 1 second. lamp 3
In UL, contact 3XFb ₁ is open and contact UHb ₂ is also open during rising, so only PC−WLDa ₂ −FLKb−3UKa−3UL−NC is valid. Therefore, in conjunction with the opening and closing of the contact FLKb, the rising hall lantern 3 of the 3rd floor landing
The UL will flash to provide guidance to passengers. On the other hand, lantern 4DL continues to light without being affected by the opening/closing of contact FLKb because contact 4XFb ₁ of the parallel circuit is not open.

In FIG. 3, both contacts UHb ₁ and WLDb are open, so the boarding refusal light DNL does not light up. When the door begins to open, the lamp UHL lights up due to PC−WLDa ₁ −DCRb ₂ −UHa−UHL−NC, the ascending direction light 9 shown in Figure 1 lights up to guide passengers, and the door fully closes. When contact DCRb ₂ opens, lamp UHL turns off, relay 3UK also turns off, and lamp 3UL turns off.
The lights also go out.

When the car rises further and relay 4XF opens,
When deceleration command relay SLD turns off, relay UH turns off, and since relay 4DK is on, relay DH turns on.

Therefore, since PC−WLDa ₂ −FLKb−4DKa−4DL−NC, lantern 4DL blinks in synchronization with the opening and closing of contact FLKb.

Inside the car in Figure 4, there is a lamp as well as on the third floor.
DNL goes out, PC−WLRa ₁ −DCRb ₂ −DHa−DHL−NC, and descending direction light 10 and DHL light up from when the door begins to open until it is completely closed.

(2) When the car stops with only a car call (not the final call) For example, if the car is on the 1st floor and relay 3UK is on, and the car call stops on the 2nd floor,
Rising (relay UH is on) and relay 2
Since UK is off, lamp 2 is shown in Figure 4.
Both UL and 2DL are not lit, and the hall lanterns are off in both directions.

In Figure 3, contact UHb ₁ opens inside the cage, and contact
Since WLDb is also open, the no-ride light DNL is off.

The lamp UHL is lit when the door is open PC-WLDa ₁ -DCRb ₂ -UHa-UHL-NC to guide passengers.

(3) When the last car call is the only car call and the car stops (when there are no other car calls or assigned hall calls) For example, when a car that has been ascending stops due to the last car call on the third floor, relay UH, Both DH turns off, decelerates, and stops. In Figure 4, both relays 3UK and 3DK are turned off, so the hall lantern is off.
On the other hand, in FIG. 3, when the door is open PC-UHb ₁ -DHb ₁ -INDb-DCRb ₁ -DNL-NC, the boarding refusal light 11 is turned on. On the other hand, the contact
Both UHa and DHa are open, and the lamps UHL and
Both DHL and DHL are turned off. That is, when viewed from the landing side, the hall lanterns 7 and 8 are turned off, the direction lights 9 and 10 inside the car are also turned off, and only the boarding refusal light 11 is turned on to clearly inform passengers that they are not to board the car.

(4) When a car in dedicated operation arrives Since relay IND is on and WLD is off, contact WLDa ₂ opens in Figure 4 and all hall lanterns are turned off. In FIG. 3, the contact INDb is open and the boarding refusal light 11 and DNL are turned off. Contact WLDa ₁ is also open, and both lamps UHL and DHL are off. This is because since the vehicle is driven by a driver, the driver's will is given top priority, and the driver is responsible for calling out to the boarding area. On the other hand, the contact INDb may close and the boarding refusal light 11 may be turned on in order for the driver to refuse boarding to general passengers.

(5) In case of inspection failure, etc. Since relay WLD is off and IND is off, contact WLDa ₂ is open in Figure 4 and all the hall lanterns are off. In FIG. 3, when the door is open PC-WLDb-INDb- _DCRb1 -DNL-NC, the boarding refusal light 11 lights up to prevent boarding. At this time, the direction light lamp UHL inside the car,
Both DHL lights are off because contact WLDa ₁ is open.

As a result, when the door is opened or closed during inspection work, for example, the boarding refusal light 11 lights up while the door is open to notify the user.

In the other embodiment shown in FIG. 5, the same parts as those in FIG. Fifth
In the figure, a floor 12 and a rear side plate 13 inside the car are shown. FIG. 6 shows an example of characters displayed on the boarding refusal light 11. This embodiment may be used in conjunction with that of FIG. Further, the information may be displayed on the upper part of the operation panel inside the car.

Note that the present invention can be implemented regardless of the number of elevator groups, the number of floors, speed, control method, etc. In this embodiment, an elevator with a forecast light has been described, but it is also possible to use the elevator with only a landing light function without a forecast function. Furthermore, the boarding refusal light may not only be lit but may also be blinking.

〔Effect of the invention〕

(1) Elevator systems equipped with forecast lights can prevent passengers from boarding cars other than those predicted, minimize unexpected car movements, and improve forecast accuracy.

(2) If the final call is only a car call and there are no other assigned hall calls, passengers will not get lost even if the car is stopped without direction, so if this car is decelerated and the door is open. Evaluation can be calculated as a car that is not restricted to hall calls. Therefore, it is the most rational system.

(3) By turning on the boarding refusal light inside the car when the car is called on a first-come, first-served basis, the same effect can be achieved at a lower cost than installing a boarding refusal light at the landing.
