Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator group management control device that is provided with a hall lantern that displays a forecast allocation in a hall and controls a plurality of elevators as a group, and particularly relates to an elevator group management and control device that controls a plurality of elevators as a group. About WLIRS, an elevator group management system with an improved registration method.

[Technical background of invention! ] Conventionally, the common method for registering hall calls for elevators that operate on multiple floors is for passengers to press a hall call registration button (hereinafter referred to as a hall button) in the ascending or descending direction provided at the hall. The call in the pressed direction is registered, and at the same time the elevator car (hereinafter referred to as the car) responds, the passenger is notified that the call has been registered, and the lamp of the pressed hall button (hereinafter referred to as the hall lamp) responds. is lit, and the light is controlled to remain lit until the car reaches that floor (starting deceleration).

In addition, as shown in Figure 8, multiple (3 or more) elevators are installed adjacent to each other on the same floor, and boarding hall calls are handled by group management 11JIII.
Hall call registration in the case of a so-called group control elevator that uses the illumination device is as follows. In Figure 8, 1
The hall door of the basket, 2 is the hall lantern, and 3 is the hall button.

First, when a passenger presses the hall button 3 in the ascending or descending direction provided at the landing, the group management control device registers the call, selects the car suitable for responding to it, and sends a response command to the main control panel. put out. (Hereinafter referred to as allocation) Then, the allocated car 1 responds to the call as described above, and has the following functions in addition.

That is, at the landing of the group control elevator, a hall lantern 2 for ascending and descending directions as shown in FIG. 8 is provided for each car. Its purpose is as follows.

As mentioned earlier, the hall call registration signal of the group control elevator is read into the group control control device, and the hall button 3, which is operated to select and allocate an appropriate car from among all cars, is placed next to the hall button 3. There is no guarantee that the car will respond. In some cases, it is quite conceivable that the car located farthest away will respond.

Taking these things into consideration, when a hall call is registered and assigned, the hall lantern 2 is turned on to notify the passenger who operated the hall button 3 and other passengers of the car to be answered, and to alert the passengers. , that hall door 1
It is to guide them to the vicinity.

[Problems with background technology]

Conventionally, a hall call was registered by a passenger pressing a hall button provided at the hall.

Therefore, one or more hall buttons (with lamps) had to be installed at every landing. As a result, the following problems occurred.

■ Since multiple hall buttons with the same function are installed in each hall, not only does the equipment cost increase, but the power consumption of the lamp with the built-in button increases, and the cost of maintenance such as lamp replacement is also significant. Also, they became thicker in proportion to the number of floors.

The above item (2) will be explained in detail below.

Usually, the hall button of the group control elevator is often placed in the middle of each elevator when a plurality of elevators are installed next to each other as shown in FIG. Further, as shown in FIG. 8, the number increases as the number of elevators increases, such as 2 in the case of 3 elevators and 2 to 3 in the case of 4 elevators. Additionally, multiple hall buttons and hall lamps installed on the same floor are usually electrically connected in parallel, so that no matter which hall button is pressed, the call is registered in the same way and all the lamps are lit at the same time. ing.

Therefore, in the case of a hall like the one shown in Figure 10, even though there are multiple hall buttons, the hall buttons near the entrance are frequently used, but on the other hand, the buttons at the back may not be used as much. many.

Also, even in buildings where there are always multiple passengers, such as a multi-tenant hill such as an office building, if one hall button is pressed, all the lamps will light up, so other hall buttons are unlikely to be operated. However, since the hall lamps are of course electrically connected in parallel, all the hall lamps in the same direction as the pressed hall button are turned on as shown in the time chart of FIG. In this way, there are many wasteful points in terms of equipment costs and power saving. However, there was a problem in that it was difficult to eliminate or reduce the number of hall buttons from a customer's perspective.

■ This is a design problem. That is, since the hall button must be installed in a place (position) that is easy for customers to operate, it is generally installed near the hall door in many cases. Therefore, the wall of the hole must be processed.

Additionally, depending on the material of the hall walls, some were difficult to process.

[Object of the invention] The present invention was made in view of the above circumstances, and
The purpose of this is to detect when a passenger enters the hall (or the presence of a passenger) and automatically register the hall call, thereby eliminating the need for hall buttons and saving passengers the trouble of pressing hall buttons. Another object of the present invention is to provide an elevator group management control device that can realize elevator hall call registration that enables rapid response to hall calls and greatly improves service to passengers.

[Summary of the Invention] In order to achieve the above object, the elevator group management control device according to the present invention is provided with a detection means for detecting the presence or absence of passengers and their approach in the hall, and detects whether a passenger has entered the hall based on the output of this detector. Once this is known, the cars are allocated in both directions, ascending and descending, and the hall lantern is turned on, and when the output of the detector detects which car a passenger is approaching, that allocation is left as is, and the car with no passengers is used. The feature is that the allocation is canceled when it is determined that the allocation has not been made.

[Embodiment of the Invention] An embodiment of the elevator group management control device according to the present invention will be described below with reference to the drawings. First, before explaining the embodiments, the principle of the present invention will be explained. In other words, a passenger detector (■) (hereinafter referred to as detector (I)) is installed in the hall on each floor (for example, near the entrance) to detect when a passenger enters the hall, and perform group management under these conditions. The control device first allocates cars suitable for calls (virtual) for ascending and descending directions of the floor, and lights up hall lanterns provided for each of the two assigned cars to guide passengers. At this time, the passenger thinks that he or she will go near the hall door of the car, which is carved in the direction he or she wants to go. After a certain period of time (e.g. 2 to 3 seconds, depending on the size of the hall), the assigned car is checked by a passenger detector (■) (hereinafter referred to as the detector (IF)) installed in each car. , detect the presence or absence of passengers near your door. If there are no passengers at this time, a call cancellation signal is sent to the group control device, and the call (
virtual) was canceled, and the hall lanterns that had been lit were also turned off. Conversely, if there are passengers, the allocated car is controlled to respond to the call.

Next, the configuration of an embodiment of the present invention will be described.

FIG. 10 is a cross-sectional view of the hall, and 5 indicates a cage, which is expressed as mA to kF (No. 6 machine configuration) for convenience. 4 is a detection B (1>) which is output when a passenger M enters the hall. Figure 5 (a) is a front view of the hall door, and Figure 5 (b) is a side view thereof. In the figure, 2 is a hall lantern, and 6 is a detector (I[) that outputs an output when there is a passenger in the shaded area.

Figure 1 shows the detector (

The main control panel MC, which is equipped with input/output section output section 0 port) GCc and GCd, and which corresponds to 1 mA to H, is the calculation section MCa.
, a storage section MCb in which control data is stored, an input/output section (I10 port) MCc, MCd, and a detector (I
) 4 are provided for each hole, and operate according to the flowchart shown in FIG.

Figure 3 shows the detector (■) 6 and main control 1M for each elevator.
An example of the system configuration of G and Hall Lantern 2 is shown,
Detector (■) 6 and hole lantern 2 are installed for each hole.
They are individually provided and operate according to the flowchart shown in FIG.゛Figure 9 shows the group management control system main body GC and main control equipment r! The input and output status of the IMC (hereinafter referred to as the I10 port) is shown, and FIG.
° state, U is the state for upward allocation (1 if there is an allocation basket), D is the state for downward allocation (same as U), LJL is the canceled state for upward allocation M (
If a cancel basket exists, 1) DL indicates a canceled state (same as UL) for the downward allocation.

In Figure 6, (b) is 1st grade tllll! MO(7)I/(1
- U and D are assigned in the upward or downward direction, respectively!
! ! (1 when assigned), LJL and UD are in the canceled state when the assignment is in the upper limit or downward direction (1 when a cancellation request is made), HtJ and HD are in the hall lantern output state in the upward or downward direction, respectively, and MD is The output state of the detector (■) 6 is shown.

The contents of the I10 boat are configured in bits, and the 〉〉 bit corresponds to the first floor, the 〉〉 bit corresponds to the second floor, and so on.

Therefore, in the case of FIG. 6(a), the detector (■) 4 on the fourth floor outputs an output that is assigned to the ascending and descending directions, but there is a request to cancel the assignment from the cage that was assigned to the descending direction. This also means that there are already cars assigned to the ascending and descending directions to the 2nd floor, and there is already a cage assigned to the ascending direction to the 7th floor.

In the case of Figure 6 (1)), there is an assignment for the ascending direction on the 2nd floor and the descending direction on the 5th floor, but since there is no output from the detector (■) 6 on the 4th floor, the assignment is canceled. It means there is.

Next, a case will be described in which the operation of this embodiment having the above configuration is applied to the hall shown in FIG. 10. For example, assume that a passenger enters the hall on the 5th floor and reaches the x1 position. Then,
The detector (1) 4 detects this and outputs a signal to the group management controller main body GC shown in Figure 1, and the flag on the I10 port shown in Figure 6 (a) is set to "1" at the 4th bit. As a result, the 4th bit of the U, 0 flag on the I10 port also becomes 1'', and the state is the same as when the call in the ascending and descending direction of the 5th floor has been registered, and this call (virtual call) is set. ), 118818 aircraft are assigned to the ascending direction, and NfiE@ aircraft is assigned to the descending direction.

The I10 port in FIGS. 7(a) and 7(b) shows the state at this point. That is, "1" is set in the 4th bit of the U flag and the 4th bit of the HU flag on the I10 port of the NQB. In other words, NQB is assigned to the ascending direction of the 5th floor, and the hall lantern in the ascending direction is lit. On the IIQH machine, on the contrary, it is assigned to the descending direction of 51@, and the hall lantern in the descending direction is lit.

After a certain period of time, a detector (■) installed in each car
6 to check whether there are any passengers near the door.

In other words, the passenger is guided by the hall lantern 2, and by detecting where the passenger moves, the direction the passenger wants to go is determined.

This state is shown in FIGS. 7(c) and 7(d). That is, passenger M
is at ×2 location, so only detector (■) 6 of IIQB detects the passenger, and MO flag of I10 map of Zui B <4
> Set “1” to the bit.

Conversely, in the case of IIQH, the fourth bit of the MD flag becomes 0''.

As a result, in order to cancel the allocation, the IIIQE machine sets "1" in the 4th bit of the DL flag of the I10 map, as shown in FIG. 7(f). Then, the HD flag <4> bit also changed from “1” to “0” and the allocation was canceled, so the D flag <4> bit also changed from “1” to “0”.
1" changes to "0'". Also, since "1" is set in the 4th bit of the MO flag for kB, the assignment remains as is and the operation is performed in the same way as normal hall call response.

As described above, in this embodiment, the passenger can automatically use the car in the direction he/she wants to go without any operation.

[Effect of the invention] As described above, according to the present invention, whether there are passengers or not.

Detection means for detecting approach is installed in the hall, and when it is known from the output of this detector that a passenger has entered the hall, the cars are assigned to both ascending and descending directions, the hall lantern is lit, and the output of the detector When a car that a passenger approaches is detected, its allocation is left as is, and the car with no passengers is determined to be unused and the allocation is canceled, so when a passenger enters the hall, the allocation will be automatically canceled. It is now possible to register for a hall call in a timely manner, which saves passengers the trouble of having to go to the elevator hall door and press the hall button, and enables quick responses, greatly improving service to passengers. The hall button can now be released, reducing equipment costs, reducing power consumption of lamps, eliminating lamp replacement work during maintenance, and providing an economical elevator group management control device with high energy-saving effects.
