Description

Elevator guide device {POSITION DISPLAY APPARATUS FOR ELEVATOR}

The present invention relates to a technology for informing the user of the location information of the elevator (elevator) installed in the building, such as a large residential complex, department store, and the like through the elevator guide device, in particular by installing the elevator guide device in various places of the building The present invention relates to an elevator guide device adapted to display the position and to display the congestion degree of each elevator.

FIG. 1 is a layout view of a lift for explaining a lift guide system according to the prior art, and FIG. 2 is a signal flow diagram illustrating a lift guide information recognition process according to the prior art. .

If each user (1A ~ 1C) wants to know the location information of the elevator, there was no way other than using the information desk (3A) or refer to the signs installed throughout the building.

In other words, as shown in FIG. 2, the users 1A to 1C arrive at the building (SA1), and the direct search method (SA2), a guide desk, and a method for searching for any elevator group among the plurality of elevator groups 2A to 2D are provided. (3A), how to inquire around people (SA3), and how to refer to the information board (SA4). Here, the elevator groups 2A to 2D mean a system in which a plurality of elevators are installed and operated in each group.

In this way, after finding the elevator group, it is determined whether the elevator is capable of serving the desired floor (SA5), and if the service is available on the desired floor, the passenger will board the elevator (SA6). It will be done repeatedly. Through this process, they arrive at the desired floor and perform their work (SA7).

In the layout of the building as shown in FIG. 1, the user 1B is taken as an example to describe a process of using the elevator in detail.

Assumption 1: User 1B wants to go to the eighth floor.

Assumption 2: The first elevator group 2A is 50M away from the user 1B, exhibits 30% congestion, and the serviceable floors are 1-8 floors.

The second elevator group 2B is 80M away from the user 1B, exhibits 5% congestion, and the serviceable floors are 1-16 floors.

The third elevator group 2C is located at a distance of 80M from the user 1B, exhibits 10% congestion, and the serviceable floors are the first floor and the 17-24 floors.

The fourth elevator group 2D is located at a distance of 30M from the user 1B, and has a congestion of 10%, and the serviceable floors are the first floor 25 to 32 floors.

Result 1: When the user 1B moves to the first elevator group 2A, the service is possible, but it is complicated, so the elevator must wait for a long time.

Result 2: When the user 1B moves to the second elevator group 2B, the moving distance is somewhat longer, but the service is possible and the degree of congestion is very low.

Result 3: If the user 1B moves to the third elevator group 2C, the user 1B must move to another elevator group because the moving distance is too long and service is not possible.

Result 4: If the user 1B moves to the fourth elevator group 2D, the moving distance is close, but the service is not available, so the user 1B must move to another elevator.

CONCLUSION: In the above derivation process, the user must move to the first elevator group 2A or the second elevator group 2B in order to use the elevator, and in order to avoid congested elevators, the second elevator group ( Move to 2B). The reason why users 1A to 1D are confused when selecting elevator groups 2A to 2D is because the elevator can be serviced at its current location in any case, such as contacting the information desk 3A or asking a neighbor. This is because information about the congestion level of the floor or the elevator is not known.

Particularly, in a complex building, the service floors of elevator groups 2A to 2D can be changed at any time or by an administrator to improve the service efficiency of the elevator. It is difficult to know the exact information. In addition, since users have a characteristic that they want to use the elevator closest to them, the users (1A ~ 1D) are concentrated in a specific elevator, which is the main cause of the deterioration of the driving performance of the elevators installed in the building.

In other words, some elevators have fewer users, so the waiting time for the elevator is short, and some elevators have a longer time for the elevator to be concentrated. The problems raised above become more serious as buildings become more complex and larger, and compared with today's building trends, the problems raised above are expected to occur in large buildings in the near future.

As such, when using a conventional elevator guide device, the user may contact the guide to determine the location of the elevator to be used, or go to the elevator by referring to the guide plate installed at a specific location, which is inconvenient accordingly. There is a problem in that it is not easy to obtain accurate guide information through a route, such as a visit to an elevator that does not serve a desired floor, and thus suffers even more inconvenience. In addition, while the elevator close to the doorway is crowded, the elevator farther away from the doorway becomes more busy, which results in a concentration of users, which causes a problem that the operating efficiency is lowered as a whole.

Therefore, the technical problem to be achieved by the present invention is to display a group of elevators that can be serviced on the target floor when the user inputs the desired target floor using the floor button mounted on the elevator guide apparatus, and the relative distance and the corresponding distance from his position. The present invention provides an elevator guide device for presenting a congestion state of an elevator group.

Figure 4 is a detailed block diagram showing an embodiment of each guide device 33A-33N in Figure 3, as shown in this, the position, distance, etc. of the elevator group stored in the ROM (eg, EEPROM) 12 A central processing unit (11) which reads the fixed information of and initializes the elevator information table held in the RAM (13), and performs the overall control function of the guide device according to the program stored in the ROM (12); A communication control unit 14 receiving congestion and serviceable floor information of each elevator through the communication management unit 31C of the elevator guide main unit 31; A communication buffer 15 for transmitting the data received through the communication control unit 14 to the CPU 11 so as to update the elevator information table; An image buffer 16 for storing screen information to be output to the elevator guide display unit 18 under the control of the central processing unit 11; An output control unit 17 for displaying the screen information stored in the image buffer 16 on the elevator guide display unit 18; An input control unit 20 for analyzing and storing an input key code selected on the key input unit 19 by the user; It consists of an input buffer 21 for transferring the input key code stored in the input control unit 20 to the central processing unit 11 side, in detail with reference to Figures 5 to 14 attached to the operation of the present invention configured as described above. The explanation is as follows.

First, referring to FIG. 3, how the overall location information and mixed information of the elevator are processed will be described as follows.

The plurality of elevator groups 32A to 32N periodically process congestion information and serviceable floor information of each elevator in the format as shown in FIG. 7, and then operate the database through the communication management unit 31C of the elevator guide main device 31. It transmits to the 31A side, and this running state database 31A is maintained in the form as shown in FIG. The guide information generating unit 31B changes the data stored in the driving state database 31A into the structure as shown in FIG. 14 and then transmits the data to the respective guide devices 33A-33N installed in the building through the communication manager 31C. Each of the guide devices 33A-33N has an internal configuration as shown in FIG.

Therefore, the data as shown in FIG. 14 is stored in the communication buffer 15 through the communication control unit 14 in each guide device 33A-33N. The data stored in the communication buffer 15 are read and separated by the central processing unit 11, and the elevator information table having the structure shown in Fig. 6 is updated by the separated data so that the position of each record is transmitted data. It is determined by the elevator group ID. The elevator group information table of FIG. 6 resides on the ram 13 of each guide device 33A-33N installed in the building.

Since the position information and moving distance on the screen in the table are fixed information which does not change after the elevator is installed, it is stored in the ROM 12 which is a nonvolatile memory and read when necessary, and the congestion and serviceable floor information are stored in the elevator guide main device ( Information received from 31 is periodically updated by the central processing unit 11.

The floor plan image of the building displayed on the building floor plan 7A of FIG. 8 is scanned by an image input device 34 such as a scanner and stored in the ROM 12, which is stored in the RAM 13 when the screen of the guide device is displayed. It is output in combination with driving status information.

On the other hand, the operation of each of the guide devices 33A-33N will be described in more detail as follows.

The central processing unit 11 reads the fixed information such as the position and distance of the elevator group stored in the ROM 12, initializes the elevator information table as shown in FIG. 6 held in the RAM 13, and stores the information in the ROM 12. Read the stored program and execute the corresponding control function.

The communication control unit 14 receives and stores driving data of each elevator from the elevator guide main unit 31, and the central processing unit 11 stores data stored in the communication control unit 14 through the communication buffer 15. It reads periodically and updates elevator information table.

The image buffer 16 stores information to be output to the elevator guide display unit 18, and the output control unit 17 performs a function of outputting screen information stored in the image buffer 16 to the elevator guide display unit 18. do.

When the user presses an input key on the key input unit 19 to retrieve the elevator guide information, the input control unit 20 interprets the corresponding key code and converts it into a key value used in the system, and the converted key value is input buffer. Stored at 21.

The CPU 11 periodically reads the value stored in the input buffer 21 and determines whether the user has requested the elevator guide information for a certain floor based on this.

For reference, the elevator guide indicators 18A to 18E, 18F, and 18G belonging to each elevator guide display unit 18, as shown in FIG. It was installed in the central passage of the mall group (4A, 4C, 4D, 4E, 4F) and the rest space (3B).

In addition, the information table for the elevator guide device held in the ram 13, as shown in Figure 6, the position on the screen of each elevator group (2A-2D), the moving distance to each elevator group (2A-2D), each The congestion degree of the elevator groups 2A to 2D and the serviceable floor information of each elevator group 2A to 2D are maintained. Here, the position on the screen is set with coordinates on the screen of each elevator guide indicators 18A to 18G, with the left and bottom corners being (0,0). That is, it means that the first elevator group 2A in FIG. 5 is located at 200 on the X axis and 100 at the Y axis.

The format of the data periodically transmitted from the elevator groups 32A-32N to the elevator guide main unit 31 is the group ID (identification number) of the elevator group group, the driving performance (congestion degree) of the current elevator, as shown in FIG. It consists of service floor information. Here, the group ID of the elevator is used to determine the group of the elevator when the elevator guide receiving the data updates the information, and the congestion and serviceable floor are used for updating the elevator information table of FIG.

The screens of the elevator guide indicators 18A to 18G have a format as shown in FIG. 8. That is, the planar area 7A of the building as shown in FIG. 5, the touch key input unit 19, and the driving state display area 7B of the elevator group. Here, the arrangement position of each elevator group 2A to 2D and the current position of the user are displayed in the floor plan area 7A of the building, and the button type of the floor on which the user wants to move is installed in the touch key input unit 19. The floor input of the user is accepted, and the operation state display area 7B of the elevator group indicates whether the elevator groups 2A to 2D are serviceable for the floor input by the user, and moves between each elevator group 2A to 2D. The distance, the degree of congestion of each elevator group 2A-2D, is displayed.

Meanwhile, referring to FIG. 9, a process of using the elevator guide indicators 18A to 18G installed on each floor of the building as shown in FIG. 5 will be described below.

When the user enters the building, find a lift guide indicator near the current position among the plurality of elevator guide indicators 18A to 18G (of course, refer to the guide plate presented in the prior art, and the information desk inquiry method is used as it is). When the floor key is pressed on the input unit 19, the elevator information can be inquired by the information output processing routine as shown in FIG.

That is, the CPU 11 uses the elevator information maintained as shown in FIG. 6 after recognizing that the floor key is pressed by the key input unit 19 through the input buffer 21 as described above. The information on the driving state display area 7B of the elevator group shown in Fig. 8 is generated and displayed on the screen of the elevator guide apparatus. Check the location of the corresponding lift group and move to that location to board the lift.

The elevator layout shown in FIG. 5 is displayed as it is in the plan view area 7A of the building shown in FIG. 8, and the elevator guide indicator currently being used by the user among the plurality of elevator guide indicators 18A to 18G is displayed in a flickering form. The user can know his location, and when the floor key is pressed, the serviceable elevator group is displayed in a flickering form.

The elevator information table shown in FIG. 6 maintained in the elevator guide devices 33A-33N presented in the present invention is updated by the elevator information response processing tutin shown in FIG. 11 and the reception processing routine shown in FIG.

The elevator arrangement diagram of FIG. 5 shows that a plurality of elevator guide indicators 18A to 18G are installed differently from the conventional arrangement diagram of FIG. 1, and the user 1B uses the elevator guide apparatus according to the present invention to the eighth floor. The process of moving is described as an example.

The user 1B will move to the elevator guide indicator 18E closest to his position, where he will press the eighth floor rising key on the key input section 19 looking at the screen of the guidance device as shown in FIG. Accordingly, the central processing unit 11 of the elevator guide apparatus generates elevator information through the process shown in FIG. 10 and displays the result in the driving state display area 7B of the elevator group on the guide screen of FIG. 8.

Each piece of information in the driving state display area 7B of the elevator group is generated by the elevator guide devices 33A-33N combining the driving state information received from the elevator guide main device 31 as shown in FIG. Extracted from

That is, since the first elevator group 2A and the second elevator group 2B can be serviced on the eighth floor, they output "OK" data for "service available", and the third elevator group 2C and the fourth elevator. Since the group 2D cannot be serviced on the eighth floor, the group 2D outputs " NO " data. At this time, the determination of the serviceable layer is based on the value ("0" or "1") of the corresponding bit. In other words, in the case of the eighth floor ascending operation, if the eighth bit of the uplink serviceable layer information is "1", the service is available.

The "congestion degree" is displayed by the data received through the above path, and the "travel distance" is the ROM (since the distance between each elevator group 2A-2D and the elevator guide indicators 18A-18G is physically fixed). 12) and display it.

The user 1B who has outputted the above and displayed the displayed result will select the desired elevator group from the first elevator group 2A or the second elevator group 2B. At this time, since the user 1B already knows information about whether each elevator group 2A to 2D is capable of serving the floor desired by the user, and how crowded it is, the problems raised in the prior art do not occur.

As described in detail above, the present invention provides a plurality of elevator guide indicators on each floor of the building, and when the user inputs the desired target floor by using the floor buttons mounted on the elevator guide device, a group of elevators that can be serviced is provided. In addition to displaying on the elevator guide indicator, by displaying the relative distance from their position and the congestion state of the corresponding lift group, not only can provide convenience in use, but also can improve the driving performance.
