CONSTITUTION:A response floor accommodatable number of person in every elevator is calculated and set by a control means 9 from a hall call assigned quantity in each elevator. Further detection information of each in-cage riding number of persons, obtained from a detecting means in every response to an assigned hall call of each elevator, is compared with the above obtained response floor accommodatable number of persons in the control means 9, when the in-cage riding number of persons exceeds the response floor accommodatable number of persons, a notifying output is generated for the corresponding elevator. This notifying output is given to the corresponding one of the notifying means 14A,...,14H provided in each elevator, and excess of the number of persons is notified in an elevator cage by this notifying means.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator group management control device that operates a plurality of elevators for a plurality of floors. This invention relates to a group management control elevator system that can minimize the

(Prior art) In recent years, when multiple elevators are installed together, in order to improve the operating efficiency of the elevators and improve the service to elevator users, the elevators that respond to hall calls on each floor have been equipped with microcomputers, etc. Efforts have been made to allocate information rationally and quickly using small computers. That is, when a hall call occurs, the most suitable elevator to service the hall call is selected and assigned, and other elevators are not allowed to respond to the hall call. The above-mentioned selection of elevators is performed by performing a prescribed evaluation calculation for each elevator based on the current operating status of each elevator and the landing floor information from already registered car calls and semi-car calls. This is done by allocating new hall calls to elevators with good evaluation values. In group management control, when the service elevator number for such a newly generated hall call is determined, the warning light on the floor where the new hall call occurred (the elevator hall where the hall call button was pressed) of that elevator number is turned on. Then, the elevator waiting customers are informed that the elevator has been assigned as a service car. When the elevator is servicing the floor, a chime or the like is used to notify the elevator, and the lights are turned off when the service is completed.

However, if the waiting time for the elevator determined as the service elevator becomes longer due to congestion on the middle floor or mid-floor service due to car calls from passengers who have boarded the car due to congestion on the middle floor or service response at the halfway floor, Re-do the above evaluation calculation and create a new service.
The elevator number is determined and the determined elevator is assigned. Also, when the middle floor is full,
Similarly, the service elevator number will be selected again. In such a case, the previous forecast will be canceled and the forecast will be changed.

(Problems to be Solved by the Invention) When multiple elevators are operated in parallel as described above, in order to improve the operating efficiency of the elevators and the service to passengers, it is necessary to appropriately respond to hall calls from the halls on each floor. So-called group management control, which assigns each elevator to each elevator, has been considered and is in practical use.

In such group management control, in cases where elevator users are concentrated on all floors, such as during lunch time, when a service elevator responds, the number of passengers waiting for the boarding on the serviced floor may be limited to the elevator car. In many cases, the trains fill up quickly.

In such a case, for intermediate floors other than the floors registered in the car call by operating the floor button in the car, the forecast for the service floor that was already held before the elevator becomes full in response to a hall call must be canceled. This leads to a decrease in forecast accuracy, which is a service problem. In group management with forecasting, the above-mentioned phenomenon is particularly noticeable during times of congestion, so it is desired to develop a system that can avoid such problems.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a group management control elevator system that can minimize the decline in forecast accuracy due to full occupancy during busy times.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. That is, a plurality of elevators are put into service for a plurality of floors, and a predetermined evaluation calculation is performed for each elevator when assigned to a hall call that occurs.
In a group management control elevator system that selects and allocates the optimum elevator based on the result and responds, there is a detection means installed in each elevator to obtain detection information on the number of people boarding the car, and the number of hall calls allocated to each elevator. A calculation function for calculating the number of people who can board the response floor for each elevator and setting the number of passengers who can board the response floor for each elevator; Compared to the number of people,
A control means having a function of generating a notification output to the corresponding elevator when the number of people boarding the car exceeds the number of people allowed to board the response floor, and a control means provided for each elevator to obtain the notification output from the control means. and a notification means for notifying the excess number of people in the car of the own elevator.

(Function) In such a configuration, each elevator is provided with a detection means for detecting the number of passengers in each car, and detection information on the number of passengers in each car can be obtained from this detection means. On the other hand, the control means calculates and sets the number of people who can board the response floor for each elevator from the number of hall calls assigned to each elevator, and further calculates and sets the number of people who can board the response floor for each elevator, and further calculates and sets the number of people who can board the response floor for each elevator. The detection information is compared with the number of people who can board the response floor, and when the number of people who can board the car exceeds the number of people who can board the response floor, a notification is output to the corresponding elevator. This notification output is given to the corresponding one of the notification means provided for each elevator, so that while the notification output is obtained from the control means, the notification means indicates that there are too many people in the car of the own elevator. will be notified. Furthermore, if each hall of each elevator is provided with a display means for guiding the number of people who can board the elevator, and the control means is provided with a display control function of information on the number of people who can board the response floor. It is possible to control the display of the calculated number of people who can board the response floor on the display means for guiding the number of people who can board in the hall where the corresponding hall call is generated in the elevator assigned by the hall call, so that up to how many people can get on the elevator waiting in the hall. This will allow you to be notified in advance.

In this way, when a hall call occurs, this system determines the service elevator and notifies the hall, calculates the number of people who can board the hall on the floor where the hall call occurs, and notifies the hall, and responds to the hall to which the hall call is assigned. When the number of passengers exceeds the maximum number of passengers allowed to board the elevator, a notification is output to the car of the responding elevator, and the set value for this notification is notified to the hall. By setting the number to correspond to the number of people who can board, it is possible to proactively prevent response floors in the middle from becoming full, and it is also possible to provide equal service to each floor even during extremely peak hours, thereby preventing a loss of forecast accuracy. This makes it possible to provide a group management controlled elevator system that does not require a group management system.

(Example) An example of the present invention will be described below with reference to the drawings.
Here, we will take as an example a case where there are 10 service floors and 8 elevators.

FIG. 1 is a block diagram showing the configuration of this device. In the figure, 1 is a hall call command registration circuit. When registering a hall call command, registers for the corresponding floor and direction are set, and the car receives the hall call command. This will be reset when you arrive at the floor. 2A to 2H are 8 from A to H.
An elevator operation control device provided for each of the elevators, including car status buffers 3A to 3H, car call command registration circuits 4A to 4H, and semi-car call command registration circuits 5A to 5.
H, signal synthesis circuit 6A to 6H, driver 15A to 15H
1 Overload buzzer 14A to 14H 1 Display for guidance display 16A to 16H provided for each hall 1 Display for guidance display 17A to 17H provided in the elevator car.

Elevator operation control devices 28 to 2H are main control panels that control the operation of elevators A to H (NaA-NaH), respectively, and are connected to the wiper select circuit 7 by a wire bottom OR, and are connected to the elevator operation control device 2A. ~2
From H, the door opening/closing status of each car, the moving direction of the car,
Car status information necessary for control, such as car position, is provided in a format that matches the table format shown in FIG. Instructions such as registration of call assignments are given. Further, the hall call command registration circuit 1 is also wired-OR coupled to the wiper selection circuit 7. The wiper selection circuit 7 and the elevator operation control devices 28 to 2H are connected by, for example, a 12-bit bus.

Here, the car status buffers 3A to 3H are buffers for inputting car status information to the wiper selection circuit 7. Furthermore, the car call command registration circuits 4A to 4H are set when registering a car call command, and the car state information is input to the wiper selection circuit 7. It is reset upon arrival at the call and command registration floor. The semi-car call command registration circuits 5A to 5H store the hall call command assigned to the car, and are reset when the car arrives at the hall call command floor. The signal synthesis circuits 6A to 6H output the logical sum of the outputs of the car call command registration circuits 4A to 4H and the outputs of the quasi-car call command registration circuits 58 to 5H.

The wiper select circuit 7 is also connected in 12-bit parallel fashion to the small electronic computer (for example, a 12-bit microcomputer) 9 that controls the group management, and transmits information on each car and hall information to the small electronic computer 9. When necessary, the small computer 9 sends a sub-address signal specifying the terminal device from its own output register 10 to the wiper select circuit 7, and the wiper select circuit 7 uses this sub-address signal to select the corresponding terminal, that is, Select and connect the corresponding car or hall call command registration circuit 1, and manually register 11 using the small electronic computer 9.
The human power from the equipment selectively connected to the wiper select circuit 7 is taken in and read. Further, 12 is another output register of the small electronic computer 9, which is used to give assigned outputs, commands, etc. to designated terminals (here, quasi-car call command registration circuits 5A to 5H) via the decoding circuit 8. .

In addition to the group management control function program, the small computer 9 has a cage status table (OCT) shown in FIG. 2, a hall condition table (HCT) shown in FIG. The status information of each car obtained from the above is updated and held in the CCT, and the hole information is updated and held in the HCT, and used for evaluation calculations of group management control.

Further, the small computer 9 has output registers 13A to 13H corresponding to each machine number A to H, and the outputs of these output registers 13A to 13H are connected to one of the drivers 15A to 15H of the corresponding machine number. This is configured to control the drive. The drivers 15A to 15H provide AC drive output and each display 16A to 16H, 17A to 17H.
This is the drive source that generates the display output for the overload buzzer 1.
Buzzers 4A to 14H sound in response to this drive output, and are installed in each elevator car for each car.

Note that the output register 10 is designed to hold the current output until the blowing output is output. In addition, a load detector (not shown) for detecting the car load is provided in each of the elevator cars, and information on the detected car load is held in the car status buffers 3A to 3H. .

Next, Figure 2 shows the car status table (CCT) that displays the car status of each elevator, and stores information such as door opening/closing, running, stopping, direction, car position, and load. are doing.

Next, Figure 3 shows the hole condition table (HCT) that represents the condition of the hole, and here it shows the hole condition table (HCT), which shows the condition of the hole.
The information on whether each floor and car is scheduled to stop (hall call or car call) is stored in bits, the 10th bit is whether there is an assigned call (“1” if there is an assigned call), and the 11th bit is whether there is a hall call. (“1” if there is a hall call) is stored.

FIG. 4(a) is a partial front view of the elevator hall. What is different from conventional halls is that there is a display installed above the entrance of each elevator to indicate the number of passengers who can board each elevator (Figure 4(a) shows the number of passengers for each elevator), as shown in Figure 4(b). 16A to 16H and 17A to 17H.

FIG. 4(c) shows an example of the installation of the indicators 17A to 17H in the car, and FIG. 4(d) shows an example of the display of the indicators 17A to 17H' in the car.

Next, the operation of such an embodiment will be explained with reference to the flowcharts of FIGS. 5 and 6.

When the small computer 9 starts the program shown in FIG. 5(a), it first performs initialization in step S1. Then repeat start point (R
Proceed to page 8).

Next, in order to verify the car status of all the cars, the car condition table (CCT) is read in order from the elevator operation control devices 28 to 2H.

That is, in step S2, the car index J
is set to O (car No. A), and information about car A is read from the car status table (OCT) of car A in step S3.

The CCT is provided in the RAM of the small computer 9, and one word corresponds to one car, the 0th bit indicates the door status (“1” indicates the door is open), and the 2nd bit indicates running or stopping (“1” indicates the door is open).
The 3rd and 4th bits are the direction (the 3rd bit “1” is the downward direction, the 4th bit “1” is the upward direction), the 5th to 9th bits are the car position, and the 10th to 9th bits are the car position. The 11th bit is the car load (45% at "00", 45% to 60 at MO/1m).
%, 1101 represents 60% to 80%, and m11# represents 80% or more). The contents are periodically fetched from the car status buffers 3A to 3H in the respective elevator operation control devices f12A to 2H by controlling the wiper selection circuit 7, and updated sequentially.

When the car status information for car A is read from the CCT (S3)
Then, the process moves to 84, and the number of passengers in car J-A is counted. This process is shown in a flowchart in FIG. 5(C).

In other words, in FIG. 5(C), it looks like a door! ! Each process is performed by (2 cycles).

First, in this check, check whether the elevator door is currently open or not (S41).
When the door is closed - the door is open, the minimum load W1.11n (J) is increased to Wl.
(J) (Load when closing the door at the previous stop floor) is set and the process proceeds to symbol AO2 (S42°843).

Also, when the door is closed this time and the door was opened last time (door open - door closed), the load Wl (J) when the door is closed is stored, and the symbol AO
Proceed to step 2 (S41.S44, 545).

Note that in S45, LOAD (J) indicates the current load.

Also, if the door is closed this time and the door was closed last time as well (door closed - door closed), proceed to symbol AO2 without processing anything (S41, 54
4).

Also, if the door is open this time and the door was open last time (door open - door open), proceed to symbol AOIB (341, S42.546)
.

In the symbol AOIB, first of all, the minimum load W
(J) and the current car load LOAD (J)l11n are compared 546), and if the minimum load is larger, the minimum load is updated 547), and the process proceeds to symbol AO2.

In addition, in S46, if the minimum load W (J) is smaller than the current car load LOAD (J), the number of boarding passengers is not counted (548), and the number of passengers allowed for boarding is set at the time of determining the service car number for each floor. Comparatively 54
9) If the number of passengers who can board the vehicle exceeds the set value described later, the output register 13A is activated to sound the overload buzzer 14A.
In addition, the output register 13 is set to display data for the number of people exceeding the set value on the display 17A.
The number of people who must get off the car is displayed on the display 17A (S50). As a result, the driver 15A operates to sound a buzzer and display information for excessive personnel in accordance with the contents of the output register 13A. In symbol AO2, check whether processing has been completed for all machines (S5), and if not completed for all machines, proceed to S2.
The process returns to , updates J, and performs the above process for the B-th car, C-th car, and so on. Then, in S5, if it is determined that all machines have been completed, the process proceeds to symbol AO.

In the symbol AO, steps 86 to 86 shown in FIG. 5(b)
Normal group management control processing according to the flowchart of step S9 is executed. Here, step S8 is a process as shown in a flow chart consisting of steps 381 to S87 shown in FIG. Here, step S84
The evaluation value is calculated using FIG.

That is, in the flowchart of FIG. 5(b), HCT
The index is updated and the HCT is checked in order to search for new hall call information (S6.
7). This is an index first! is set to 0, that is, 10d), the hall condesion table HCT is sequentially incremented by 1, and if there is an unallocated hall call that has been pressed but the hall call button has not been allocated yet, the allocation processing routine is executed. and allocates the service number for that hall call. Here, when the hall call button is pressed, the registration light of the hall call button is lit, and only the 11th bit of 10d is "
Let it be 1°. Then, symbol D is entered and response machine selection is executed. The processing with this symbol D is as shown in FIG. 6. First, in 881, the floor of the newly generated hall call is determined according to the floor and destination direction (down/up call) indicated by the newly generated hall call. Already allocated hall calls (n 1 . . . nK) located upstream to the floor are selected.

Next, set the car index J to 0 (i.e. car number A)58
2), the selected already allocated call (nl...n K
) Estimated arrival time TRESP (n+
)(i-1, . . . , K) are calculated using the following formula (S83).

TRESP(n)−ΣTRAN Cα,β)'
m-1 ffl m I-1 +Σ TlO2(β) ... (1)■-1 Here, TRAN (α, β) is
Let us take the travel time from 1 m to the β floor, and TlO2 (β ) f1m represents the total time of door opening/closing and opening time on the 8th floor.

Furthermore, g is the number of floors (n including the 1st floor) that the car stops on the way before reaching the nt floor.

For example, if an unassigned call of 10d (downward call on the 10th floor) occurs while the car of car A is ascending the 8th floor, and at that time car A has an assigned call of 7d in the descending direction of the 7th floor, the assigned call of 7d The arrival time is expressed by the following equation (2).

T RE S'P (n 2 ) -TRAN (8,10) +TLOS (10
)+TRAN (10,7)...
... (2) Also, the arrival time of the unallocated call of 10d is calculated using the following formula % Equation % Estimated arrival time TRBSP (n,
) is weighted using an appropriate function, for example, a function f(Tj) that defines the relationship between the predicted waiting time and the evaluation value as shown in FIG. 7, and the evaluation value S is determined.

Please carry out the above operations for all machines S85゜S82~5
84), find the evaluation value S (J) of all machines (S86)
The car with the minimum S (J) is designated as the service car for the normal hall call of 10d, the output register 12 outputs its allocation to the decoding circuit 8, and the number of passengers allowed is set, and the process proceeds to symbol E (S87 ,588
).

In addition, for the answering car assigned as a service car, the forecast light on the floor where the hall call occurs is controlled to display the forecast, and the sub-car call is registered in the elevator operation control device of the assigned answering car. Do it and let them respond.

This is carried out in the same way from 9d (downward call of 9F) to 9u (increase call of 9F). The HCT is placed on the RAM in the small computer 9, and rlJ and rOJ are stored in corresponding bits depending on the state. For example, whether or not a hall call has been allocated can be determined using a combination of 10 bits and 11 bits. For example, if the 10-bit and 11-bit data of the HCT is '01', an r-hole call has occurred, an unallocated hole, and if it is '11' or '10', it is an 'allocated hole'.
If it is 00″, it means “no hall call”. In addition, for the service number of the already allocated hole, the 0th to 7th bits of the 1 word corresponding to each hole (by direction) are A.
Since the car No. 1 corresponds to the car No. H, the car corresponding to the bit whose data is "1" (car No. 1) can be determined as the car assigned to that hole.

Here, the setting of the number of people who can board in S88 is determined from the current load in the car and the number of sub-car calls (the number of calls assigned by hall calls) currently held by the own car. For example, if the elevator capacity is 20 people, the current car load is 5 people, and the number of semi-car calls is 2, then the number of people who can board each floor is 15/2, which is 7 people. You can also decide. Therefore, if the guidance information for the number of people set in this way is currently being processed for machine A, it is set in the output register 13A for machine A, given to the driver 15A of machine A, and displayed on the hall display 16A. and notify customers waiting in the hall. Note that this guidance display does not necessarily have to be performed when the set value of the number of passengers who can board the vehicle is greater than a certain number of passengers.

The process described above is carried out for all floors, and after completion of all floors, the process returns to RSP (S.9), and the same process is repeated cyclically thereafter.

In this way, when a hall call occurs, this system determines the service elevator and notifies the hall, calculates the number of people who can board the hall on the floor where the hall call occurs, and notifies the hall, and responds to the hall to which the hall call is assigned. When the number of passengers exceeds the maximum number of passengers allowed to board the elevator, a notification is output to the car of the responding elevator, and the set value for this notification is notified to the hall. By setting the number equivalent to the number of people who can board the train, we actively prevent mid-way response floors from becoming full, which allows us to provide equal service to each floor even during extremely peak hours, thereby reducing forecast accuracy. It becomes possible to provide a control method without

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the gist thereof.For example, in the above embodiments, the number of passengers in the car may be This is done by detecting the load, but it may also be done by optical detection.In addition to dividing the number of people who can board the hall when responding to a hall call, the number of people who can board the hall is divided equally, and the number of people who can board the hall when responding to a hall call is divided equally. Processing such as increasing or decreasing the ratio may be performed depending on the form of demand. In addition, this method can be used more effectively in terms of elevator service by applying measures such as time zone management during periods of peak demand.

[Effects of the Invention] As described in detail above, the present invention displays a forecast in the hall when a service elevator is determined, displays in the hall the number of people who can board at the floor where the hall call occurs, and We have made it possible to prevent overcrowding more proactively than before by issuing an over-crowded alarm when the parking lot is overcrowded, making it possible to maintain forecast accuracy even during extremely peak times such as lunchtime. Moreover, it is possible to realize a group management control elevator system capable of providing average service without biasing the service to a specific floor.
