Description

Description: TECHNICAL FIELD The present invention relates to an elevator group management control device, and in particular,
The present invention relates to a landing guide device suitable for informing a boarding elevator at a landing.

[Conventional technology]

In the group management elevator control system, efficient operation can be achieved by assigning calls to both the rising and falling directions of the same floor to the same elevator on the floor near the end floor of the elevator service floor. In such a case, if both the ascending and descending guide lights on the same floor are turned on and the service elevator is displayed, the waiting passengers may be distrusted or confused, which is disclosed in JP-A-49-948. As described, it is proposed to prevent both guide lights from being turned on at the same time, and to preferentially turn on the guide lights in the driving direction. In addition, JP-A-53-1452
It is also proposed in Japanese Patent No. 51 that the display mode is temporarily changed when the car is first arrived and the vehicle decelerates in the opposite direction to the guidance display.

[Problems to be solved by the invention]

The above-mentioned conventional technology is a technology for preventing so-called erroneous riding, in which passengers waiting at the hall get on the elevator in the direction opposite to the driving direction. Therefore, the poor driving efficiency of stopping twice at the same floor during the short time in which the elevator that started leaves for the end floor and then returns to the landing was not considered.

An object of the present invention is to perform efficient group management control without causing confusion to passengers waiting at the landing.

[Means for solving problems]

The purpose of the above is to inform the user to the elevator that the user in the direction opposite to the guide direction should also get on the elevator when the elevator is decelerating and stopping in the direction opposite to the direction in which the guide light is turned on. When it detects that you have boarded the elevator, it resets the landing call in the opposite direction to the driving direction of that floor so that you can turn to the end floor and not turn to stop on the floor. To be achieved.

[Action]

With the above configuration, the user knows that he / she goes to the end floor and makes a turn-around operation, so that he / she can get on the elevator that arrived with peace of mind. Further, since the boarding call is detected and the landing call in the opposite direction to the driving direction is reset, it is possible to perform efficient driving control without unnecessary stoppage. Further, when the boarding cannot be detected, the call is not reset, so that the passenger goes to the end floor and then returns to the above-mentioned floor, so that there is no complaint even if there is a user who has not boarded.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 shows a hardware configuration of an embodiment of the present invention.

The call signal HC from the hall call registration device HD of each floor hall is connected to the elevator group management control device MA by the serial communication processor.
Connected via SDAh. In addition, a microcomputer for controlling the elevator that controls individual elevators such as guidance output, door opening / closing, car acceleration / deceleration commands, car call signals, car position signals, etc.
E1 to EN (Here, it is assumed that the elevator has Nth unit)
Are connected to the serial communication processors SDA1 to SDAn via communication lines CM1 to CMn.

In addition, in the machine control microcomputers E1 to En, the car call information DC, car position signal CPD, etc. required for control are controlled by the control input element EI01.
To EI0n and connected via input / output circuits SI01 to SI0n. The control signals for the hall lantern HL, display HE, and voice guidance device SP at each floor are also output from the machine control microcomputer via SDAk.

FIG. 3 shows the software configuration of the group management control device MA. There is an operation control program SF14 that directly commands and controls the group management control of the elevator such as call assignment processing and distributed standby processing of the elevator, and as the program input information, the position of the elevator transmitted from the machine control program E1 to En, Elevator control data table SF11, hall and table SF12, such as direction, car call, car load, etc.
Elevator specification table SF such as the number of elevator group management
13 and operation control parameter table SF15.

FIG. 4 is a table structure of software used in the group management control device MA, which is an elevator control data table SF1.
1, Hall call table SF12, Elevator specification table SF1
3. It is composed of the blocks of the operation control parameter table SF15. The table in each block will be described each time the operation control program is explained.

The program is managed under a system program that divides the program into a plurality of tasks and performs efficient control, that is, an operating system (OS).

Therefore, the program can be started from the system timer or from other programs.

5 and 6 show a software flow chart according to an embodiment of the present invention. The program shown in FIG. 5 is a notification condition detection program and is started every second. Step E10
And the step E60 is designed to perform loop processing for all units. First, in step E20, it is determined whether the elevator is in deceleration stop. If "NO", jump to step E60, and if "YES", step E30 decides whether or not there is a call assignment in the opposite direction of the electric. Otherwise step
If there is a jump to E60, if there is a step E40, it issues an output command of a notification signal to the elevator control device of the elevator, which "guides the passenger to get on the elevator in the opposite direction to the driving direction." At step E50, the notification output flag TF is set, and the routine proceeds to step E60.

The program shown in FIG. 6 is a reset program for landing calls in the opposite direction to the driving direction, and is started every second. Loop processing is applied to all units at Step F10 and Step F80. First, in step F20, it is determined whether the elevator has started. If "NO", step F
If it is "YES" at step 80, step F30 outputs the alarm output flag TF.
Is set. If it is not set, jump to step F80, and if it is set, step F40 is used to determine whether or not a passenger has boarded the elevator. If boarding is not detected, it jumps to step F70, and if boarding is detected, it is judged in step F50 whether there is a person at the elevator hall. If not, jump to step F70, and if there is step F60, reset the landing call in the direction opposite to the driving direction. In step F70, the notification output command issued to the machine controller is reset and the notification output flag TF is reset. Here, any method may be used for the process of determining the entry of a person, and for example, there is a method of obtaining it from the load change as described in JP-A-52-140149. Further, the process for determining whether or not there is a person at the elevator hall may be any method, for example, a method using a waiting sensor as described in JP-A-50-54054. is there. In the present embodiment, the call is reset when two conditions, namely, a passenger getting in and a condition that no one is present at the landing are satisfied. However, the call may be reset with only one condition.

FIG. 1 shows a guidance state of an annunciator at a landing controlled by the machine control device. In this example, the floor is one floor lower than the top floor. It is a situation where the car is stopped on the floor where it is going up, and for the sake of explanation, the number of elevators is two. Since the method of controlling this alarm is known, it will be omitted. (A)
In (c), the guidance state progresses in this order. First,
In (a), the No. 1 unit lights the downward hall lantern in response to the downward call. In (b), Unit 1 arrived and blinked the hall lantern in the ascending direction. At this time, the hall lantern in the descending direction may be on or off, but in this example, it is on. This time,
Since the output command of the notification signal "guidance to ride in the elevator in the direction opposite to the driving direction" described in the flow chart of FIG. 5 is issued from the group management control device, the display device HE, and
The voice guidance device SP guides, for example, "please take the elevator that arrived below as well". 6th in (c)
As explained in the flow chart of the figure, when the elevator doors are closed and the passenger starts in the ascending direction, there is no user in the descending direction, so the hall call in the descending direction on this floor is reset.

In this embodiment, the notification start time is adjusted to the elevator deceleration start time.However, the notification start time is determined from the time when it is decided to go in the direction opposite to the guide direction, that is, the time when the reservation lamp is turned on. Also has the same effect. In short, the point is that people are guided when getting on and off after the start of deceleration. By notifying in this way, the passenger waiting at the landing can board the elevator that has arrived without anxiety.

As an application of the present invention, it is prohibited to stop an elevator carrying a user in the opposite direction on that floor after reversing the direction, or give priority to a landing call generated after the user gets in the opposite direction over other elevators. It is easily conceivable to allocate it to each other. It is also the same as carrying out only in a specific time zone or only in a specific floor.

FIG. 7 is an explanatory view of another embodiment of the present invention, which is a modification of the example of the floor immediately below the uppermost floor described in FIG. In this example, one landing button is installed at each of the upper and lower sides, but the hall lanterns at the landing are one for both upper and lower sides and do not have a direction. This is one hall lantern from the beginning to guide you to board the elevator that has arrived whether it arrives in the reverse direction or in the forward direction. In (a) to (c), the guidance state advances in this order. First, in (a), the No. 1 unit lights the hall lantern in response to a call in the descending direction. In (b), the first unit arrived and the hall lantern was blinking. At this time, the 8th
It is possible to judge whether there is a user going in the opposite direction to the driving direction by judging "whether a call in the opposite direction to the elevator is registered" by the flow chart in the figure. A command to output a "notification signal" is issued from the group supervisory control device. Then, the display device HE and the voice guidance device SP guide, for example, "I will go up once. Those who go down should also take the elevator that arrived". In (c), as explained in the flow chart of Fig. 6, when the elevator doors are closed and the passengers depart in the ascending direction, there is no user in the descending direction, so reset the hall call in this descending direction. ing.

FIG. 8 is a modification of the flow chart of FIG. Only the parts that are changed from FIG. 5 will be described. The part that determines whether or not there is a backward call assignment of the elevator in step G30 is changed to the determination whether or not a backward call is registered. In addition, the step
G25 has been added to determine whether the floor next to the end floor is.

〔The invention's effect〕

According to the present invention, since the user knows that he / she goes to the end floor and makes a turnaround operation, he / she can get on the elevator that has arrived without anxiety and can perform efficient operation control without unnecessary stop.
