Description

[Detailed description of the invention] [Explanation of technical field] The present invention relates to a group management control method for elevators.

I am especially curious about the way elevator lanterns are displayed.

[Technical background of the invention and its problems]

In recent years, it has become common for group management control devices to control a plurality of elevators to use small computers such as microcomputers. In such a group management control device, a so-called evaluation formula is used in rounding to determine the service elevator for a hall call request that has occurred, and as a specific example, it is attempted to average the waiting time. For example, when a hall call occurs, there is a method of determining hall call allocation so as to minimize the maximum expected arrival time of each car.

In such elevators, it is common to determine the service elevator for the hall call based on a predetermined evaluation formula at the same time that a hall call is low, and to notify the passengers waiting at the hall in the form of a display in which a hall lantern lights up.

The service elevator is determined by predicting the arrival time until it responds to the floor where the hall call occurs based on each ff traffic data at that time, but before the service elevator responds to that floor, There are cases where a non-service elevator responds to a hall call before a service elevator (hereinafter referred to as "first come, first served") because the hall call is answered because the hall call is answered, or because the elevator is full. In this case, the service elevator will have its hall lantern lit, and the first non-service elevator to arrive at that floor will have its hall lantern blinking, and in such a case, the non-service elevator will It is also conceivable that the staff will be the first to arrive at that floor.

Especially on the cafeteria floor during lunchtime (d), multiple service elevators may be designated for one hall call, that is, multiple hall lanterns may be lit.

In such a case, if a non-service elevator arrives first, it will cause great confusion among the passengers waiting at the hall.

[Purpose and outline of the invention]

The present invention has been made in view of the above points, and involves putting a plurality of elevators into service for a plurality of service floors, and performing predetermined evaluation calculations for newly generated hall calls that are common to each elevator. In a group management control method in which a service elevator is determined using a method, the number of elevator cars on the same floor and in the same direction displaying a guidance display such as a forecast display using a lantern or a landing display, for example, using a lantern, is calculated, and the number of elevator cars is calculated. If the number of elevators exceeds the specified number, the guidance display (e.g. flashing lanterns, etc.) in that hall will be discontinued for elevators that are on the same floor and point in the same direction (for example, flashing lanterns, etc.) until the condition is resolved. This prevents confusion among customers waiting in one hall, and even if there are many people on the same floor and in the same direction, by limiting the number of guidance displays, it is possible to concentrate customers waiting in the hall on the guidance display. The purpose of the present invention is to provide a display method that enables efficient group management control.

[Embodiment of the Invention] First, an outline of an elevator system to which this embodiment is applied is shown in FIG. The system schematically shown in Figure 1 consists of four elevators, A to D, as a group of 10 elevators.
It was installed in a multi-story building, with the second to sixth floors being an express zone to prevent all elevators in the group from stopping.

Such elevators A to D are shown in Figure 2 (a).
, is controlled by a group management control system configured as shown in (b).

In Fig. 2 (a) and (bJ), there is a 1-car hall call registration circuit, in which the register corresponding to the floor and direction is set when registering a hall call, and is reset when the car arrives at the hall call floor. .

2A to 2D are elevator operation control devices provided for each of the four elevators A to D, and car state memory circuits 3A to 3D and car call memory circuits 4A to 4D are provided separately. . The car status memory circuits 3A to 4D are
It is a buffer for car position, driving direction, load signals, etc.

The car call memory circuits 4A to 4D are set when a car call is registered, and are reset when the car arrives at the corresponding call registration floor. 5 is a wiper select circuit. It is a Kotoki small computer and has an output register 7, an input register 8, and an output register 9.The output registers 7 and 9 have the function of holding the same output until the next output is issued. Reference numeral 10 denotes a master conditioning storage circuit, which stores information on whether or not each elevator can be inserted into a group.This information is stored in a master conditioning table (as shown in FIG. 2(b)). It is stored in the master command storage unit 14 in the RAM (random access memory) of the small computer 6 as [MCTJ hereinafter].

In such a configuration, the wiper select circuit 5 is operated by the sub-address fFl output from the output register 7 of the small computer 6, and the required traffic data is selected from the traffic data group according to the select code output from the output register 7. are selected sequentially, and information outside the computer is transferred to the RAM inside the computer via the input register 8 of the small computer 6.
stored in the area. Based on this information, the machine number is determined for the hall call that has occurred, and the machine number is 60MM.

Ru. The output data is decoded by the decoding circuit 13 in FIG. 2(a) and stored as an assigned call in the hall call assignment memory circuits 12A to 12D of the assigned car. At the same time, this information is used to determine the hall (floor). A lantern (not shown) displays the forecast. The data stored in the hall call allocation storage circuits 12A to 12D is combined with the data stored in the hall call storage circuit 1 to form the storage data of the hall condesion storage circuit 11, and the data stored in the hall call allocation storage circuits 12A to 12D is combined with the data stored in the hall call storage circuit 1 to form the storage data of the hall condesion storage circuit 11. The information is stored in the version storage unit 16. At the same time, the lantern control circuit shown at 22 (which will probably be installed for each machine and each hall call) will be set up.

Note that in FIG. 2, a plurality of signal lines, for example, eight parallel signal lines, are shown as a single signal line that connects each circuit. Furthermore, all the registers have the number of bits equivalent to one word of the small computer 6. Further, the HCT and CCT stored in the RAM of the small computer 6 have a bit configuration as shown in FIG. Furthermore, OCT
In the above, the 0th bit indicates running or stopping; '11' indicates running, and 1()1 indicates deceleration or stopping and door opening.

The first and @2 bits indicate the service direction of the elevator, e.g. fool for no direction, '011 for up direction.
#1O@ indicates facing down.

The 3rd to 7th bits indicate the position of the elevator corner; for example, 'oooooi' means you are on the first floor, '0
0010'' indicates that you are on the 2nd floor, and ``01010'' indicates that you are on the 10th floor.

In addition, HOT has a detailed bit configuration as shown in Figure 4 (al). Here, the 3rd to 7th bits are assigned to each elevator machine as set bits for hall calls,
When the 6th bit is 111, the allocation is completed, and MQ
W indicates that the allocation has not been completed. Also, the 7th bit is 11
When it is 1, there is a hall call, and when it is 101, there is no hall call.

The presence or absence of a car call is stored in the car call storage section 21 in the RAM in the form of a car call table (hereinafter referred to as "KCT") shown in FIG. 4(b).

Here, the process from when a hall call is generated on an arbitrary floor to when a service elevator is determined for a sonohall call will be explained.

In the flowchart shown in FIG. 5, the process starts from Ql, the thief's initialization subroutine entry address is set in Q2, and the car status of each elevator is stored in the RAM via the wiper select circuit 5 in FIG. 2 (al) in Q3. CC of

Since it is given with 11ZIQl of bit, the 6th in Q5
．． Depending on the combination of the 7th bit, lOO"; no hole call, no allocation"01'; hole call, no allocation '11'; hole call, allocation '1'
0”: The hole status can be determined as the hole is called and allocated.

If these are 1001, the hall call duration counter Tj is set to 0 in Q6 and the process proceeds to D.

In the case of @101, the hall call duration counter T is set in Q9.
j = Tj + 1, calculate the number of lighting or flashing lanterns on the 5th floor using QIO, and if the number is greater than the predetermined number, only the predetermined number will be allowed to display lanterns on the same floor and in the same direction, and others will not be allowed. After outputting, proceed to D. (Ql6

After that, Qll.

Calculate the evaluation formula f in Ql2. f m in Q13 after the calculator
The in-car, that is, the smallest car of f, is determined and output as the service elevator for that call.

In the case of 1111, set Tj=Tj+1 in Ql, and from step C3, routine QIO, Q16. Execute Q17 and proceed to D.

In this way, for hall calls on all floors from J=1 to J=18, unallocated hall calls are used by service elevators.

In this embodiment, the allocation to hall calls is determined as described above. Below, details of parts particularly related to the features of the present invention will be explained.

The lantern display is HCT's 6th. A problem arises when the combination of the seventh bit is l 1o l, l t 11 .

Steps C3 to D shown in FIG. 5 are the key points of the present invention.

The details will be explained below with reference to FIGS. 6(a) and 6(b).

In FIG. 6(a), steps C3 to C4 calculate the number of lanterns displayed (lit or blinking) on the 5th floor, and store the number in the counter LCTR1. First Q2
0, Q21 determines whether or not the aircraft has landed on the 5th floor.

In other words, the car decelerates in a direction on the 5th floor or (door opens when stopped)
If so, the lantern is blinking, so LCTRI is incremented. Next, in Q23, a search is made to see if there is a forecaster on the 5th floor, and if there is a forecaster, the aforementioned counter Lc'rat is incremented. The presence or absence of a forecast error can be determined by whether the 6th and 7th bits of HC'l' are 1111 or not. In this way, step C3 to step C3
If step 2 is executed for all cars (Q25), the number of lantern display cars on the 5th floor will be stored in the counters r and c'rai.

Next, proceed to C4 in FIG. 6(b).

If LCTRI≦2 in Q26, the number of lit or flashing lanterns on the 5th floor is 2 or less, so Q33.
As is clear from Q34, a display permission signal is output to the lantern display control units on the 5th floor of all units. (A lantern display control unit, which will be described later, is installed for each lantern.)4. l,LCTR
I) If 2, check whether it is a service elevator on the 5th floor in Q28.If it is a service elevator, check the counter LC.
Increment TR2 in Q27 and enable lantern display in Q33.

If not, check in Q29 whether the 5th floor is decelerating in a direction or opening the door when stopped, and if the lantern is blinking, increment LCTR,2, and in Q31 check whether LCTR2≦2 or less on the 5th floor. If it is below, then Q3
Step 3 sets the lantern display permission output to the lantern display control unit; otherwise, step Q32 sets the lantern display disallowance output to the lantern display control unit.

The above process is executed for all machines in Q34.

In Q35, the counter LCTFL1=LCTR2=0 is set prior to the above state on the u(J+1) floor. Steps C3 to D are in the loop of hole index J in terms of software, so the above steps are performed for all floors.

FIG. 7(a) shows a lantern control display unit provided for each lantern. 1 is an OR element, 2 is a palm element, 3 is an amplifier, and 4 is a lantern.

As is clear from FIG. 7(a), the forecast signal person or landing signal B is ANDed with the lantern display control fFIR, so if the lantern display control signal R is not set, the amplifier 3 is not output.

FIG. 7(b) shows the signal relationship at points P and Q of the unit shown in FIG. 7(a). In FIG. 7(b), the signal at point Q of the lantern display control unit indicated by R is controlled.

〔Effect of the invention〕

As explained above, according to the present invention, multiple elevators on the same floor and in the same direction can display lanterns (lighting of lanterns,
lantern display is allowed for elevators with a predetermined number or less, and it is possible to stop displaying lanterns for elevators with more than a predetermined number until the condition is resolved. In addition to preventing confusion among passengers waiting in the hall due to overlapping lantern displays, it is possible to guide passengers waiting in the hall to concentrate on a specific area because the lantern display is limited, making it possible to achieve good group management control from the standpoint of elevator usage efficiency. Become.

In the embodiment of the present invention, the number of lanterns permitted to be displayed on the same floor and in the same direction is two (for example, 9 lights on, 1 blinking, 2 lights on, 2 lights, etc.), but the number is not limited to this.
