DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator multi-group control device, and more particularly, to an elevator hall (hereinafter simply referred to as a hall) common to a plurality of elevator groups in a building. An elevator multi-group control device that assigns a service to a common hall call (hall call) to these elevator groups and outputs a response command to the assigned elevator group to control the elevator group to respond to the hall calls. It is.

[0002]

2. Description of the Related Art One unit of an elevator installed in a building (that is, an elevator group) is usually called a bank, and is called a bank.
There is an elevator (one-bank) composed of cars and an elevator (group management bank) composed of a plurality of cars and managed as one group. One bank has at least one row of floor calls for each floor. One for one bank
One elevator sequentially responds to the registered hall call and the destination call registered in the car (destination call). The plurality of banks are configured such that an elevator car to answer a registered hall call is selected by the group management control device, and only the selected elevator car responds.

[0003] A bank refers to one group of elevators (ie, an elevator group) composed of one or a plurality of elevators. (In some cases, refer only group management bank say bank elevator. Here in the case of distinguishing one bank and the group management bank shall respectively clarity and one bank or group management bank.)

[0004] The elevators in one bank are controlled by a control device (unit control device). A group management bank is usually composed of a number of unit control panels and one group control panel, but the group management control unit is housed in a specific unit control panel or one unit control panel is grouped. It may have the function of the management control device.

[0005] As described above, 1 responds to a hall call and a destination call.
In the case of a bank having a set of functions, a single elevator that mainly captures the movement of an individual elevator car is referred to as a car. That is, the car number refers to the case of each elevator car unit irrespective of the entire bank, and is controlled by the car control device.

[0006] Examples of the group management control device and the unit control device have been published in various literatures and patent publications, and various types of devices which perform advanced control have already been known.

[0007] However, once these group management control devices and unit control devices are installed, the landings assigned to them are fixed, and the balance between banks is better when the ownership is changed between other banks. Even so, there was no good countermeasure because the landing itself was not prepared (the problem of traffic balance between banks).

Further, when a high-rise building is connected to a plurality of banks and goes to a target floor (in the case of setting up an elevator of a sky lobby type), the user has to wait for a long time at the connecting floor of the bank. There is also a problem that it takes a long time to reach the target floor because of the need to transit (transit problem in the sky lobby system).

[0009] As a proposal for solving the problem occurring between a plurality of banks, Japanese Patent Application Laid-Open No. 52-123050 is proposed.
JP-A-62-130986, JP-A-62-21886
374 and Japanese Patent Application Laid-Open No. 1-98579.

[0010]

The above-mentioned JP-A-52-1
According to the technique disclosed in Japanese Patent No. 23050, the operation of group management control of a plurality of banks is originally performed by the control device of each bank by one control device.
The aim was to reduce costs by suppressing the increase in control devices. However, since the problem solving process between banks by the central control device cannot be performed, neither the traffic balance problem between the banks nor the connecting problem by the sky lobby method has been solved.

According to the technology disclosed in Japanese Patent Application Laid-Open No. Sho 62-130986, when a plurality of banks are adjacent to each other and a hall call can be registered, each of the passengers can use the same hall.
Registering a hall call in multiple banks
And I want to ride as soon as possible
(Applies when registering a bank call.)
This will result in a lower rate. For this reason, once a hall call is registered, registration of a hall call in another bank is prohibited. Further, in the technique of Japanese Patent Application Laid-Open No. Sho 62-218374, it is not possible to balance between the banks by providing only the bank in which the hall call is registered earlier to the hall call as disclosed in Japanese Patent Application Laid-Open No. Sho 62-130986. A changeover switch for determining a service bank for a hall call is provided for each floor, so that a hall call registration of a valid bank is enabled.

However, the techniques disclosed in these two publications are a solution to the problem in the case where a plurality of banks are adjacent to each other and a hall call button is provided in each of them so that the same hall can be serviced. At first glance, this seems to be a proposal for the above-mentioned traffic volume balance problem between banks, but for some reason there was no problem if one group management device would normally have no problem if the whole number was concentrated and managed. This was a countermeasure against the installation of such an elevator (for example, if three group management banks are adjacent to each other, it would have been better if one group management bank originally had six groups). is there). Nevertheless,
In Japanese Patent Application Publication No. 218374, a bank for enabling a hall call can be predetermined for each hall call button by a changeover switch, so that the traffic balance between the banks can be adjusted as a result. It has been one proposal for the problem of traffic balance between the two. However, the problem of the original traffic balance was the problem of the balance of the number of service floors between the bank positioned to service the upper floor and the bank positioned to service the lower floor. For this reason, there has been a demand for a proposal for actively solving the problem of traffic volume balance between banks using a centralized control device or the like.

On the other hand, in Japanese Patent Application Laid-Open No. 1-98579,
This proposal proposes a solution to the problem of connecting multiple banks in a skyscraper with a sky lobby. A method of performing control with respect to was described. However, although the method described here to respond quickly to a hall call on the floor of the sky lobby is certainly effective at up-peaks and down-peaks, it can be used for traffic balance problems between banks. The effect was small because the floor was fixed.

In recent years, Japanese Patent Application Laid-Open No. 62-10 / 1987
As shown in Japanese Patent No. 5881 or the like, an elevator monitoring panel composed of a microcomputer or the like using a display device such as a CRT has been used.
This has a function corresponding to a control device positioned higher than a plurality of banks as disclosed in Japanese Patent Application Laid-Open No. 1-98579. The control panel of the elevator also controls the remote control, control of the unit such as waiting for return, and operation of the group management bank such as driving at work and driving at lunch. However, no proposal has been made to solve the above-mentioned traffic balance problem between banks.

As described above, the conventional elevator control apparatus is not sufficient in function and performance in solving the problem of the traffic balance generated between a plurality of banks. For this reason, there has been a demand for a proposal of a more advanced solution to the problem of the traffic balance occurring between a plurality of banks. Other precedence

An elevator control means (not shown) provided in the elevator group control device or the elevator control device determines whether or not to respond based on a response command signal from the control command output means 16. And control the elevators in each bank to answer the hall calls. For hall calls other than the common hall, which are unique to the bank, register the hall call button signal by taking the hall call button signal in the same manner as before and register it by registering (calling that the hall call button was pressed). A registered lamp is turned on by outputting a lamp lighting command. With respect to the hall call of the common hall, the button signal is fetched and transmitted to the multi-group control device, and the hall call input means 12 of the multi-group control device registers the hall call (storage that the hall call button is pressed) ( The registration lamp is turned on by the bank receiving the response command signal). Then, control is performed assuming that a registered hall call specific to the bank and a floor and direction indicated by the response command signal have occurred. That is, a car to be assigned is selected by combining the registered hall call unique to the bank and the hall call to which the common hall is assigned, and the hall call is answered. With respect to canceling the hall call, the bank-specific hall call turns off the registration lamp and cancels the registration when the elevator car responds as usual, that is, resets the memory of the press of the hall call button. For the hall call of the common hall, when the own bank receives the response command signal, the elevator control means turns off the registration lamp when the elevator car of the own bank responds, and the registration is canceled by the multi-group control device. Detects that the elevator car has responded from the elevator state information.

The principle system of the elevator monitoring apparatus according to the present embodiment is configured as described above. Next, the general operation will be described. Here, FIG. 1 will be mainly described and reference will be made to correspondence with FIGS. 2, 3 and 4 as necessary. In addition, in order to simplify the description in the future, FIG.
The following figures are also referred to as appropriate.

Among the monitoring functions of the elevator, the status of the elevator is displayed by the elevator status input means 13, the display control means 21 and the CRT display device 22 of FIG. 1, and the operation of the elevator is controlled by the display control means 21, the CRT display device 22 and the CRT display device 22. Are realized by control command registration / instruction means, control command creation means, and control command output means (not shown).

Therefore, the operation is as follows. First, the elevator status input means 13 takes in the elevator status information from the elevator banks 11a to 11g and sends it to the display control means 21. Next, the display control means 21 displays the elevator status on the CRT screen by graphics and characters according to a predetermined procedure and format (the elevator status monitoring screen in FIG. 6). In operation control of an elevator, a control command registration / instruction unit first receives an operation for control execution or control execution time reservation through an operation control screen (not shown) and inputs an execution time registration / execution instruction. . Then, the control command creation means creates a control command signal for each elevator according to the execution time registration / execution instruction, and the control command output means transmits the control command signal to the elevator control means via the transmission device to perform the operation. Let The details of the control command registration / instruction means and the control command creation means for elevator operation control here are not shown because they are not directly related to the present invention.

Next, the hall call input means 12, the elevator state input means 13, the allocation evaluation operation means 14, the control command creation means 15, the control command output means 16, and the elevator control means (not shown) in FIG. The operation of automatically realizing floor allocation (automatic allocation) that has been realized will be described.

Assuming that the landing button is pressed, the elevator control means sends a landing button signal to the multi-group control device via the transmission device, and the landing call input means 12 performs the above-described registration processing of the landing call. The allocation evaluation calculating means 14 determines the common serviceable banks based on data such as elevator state information from the elevator state input means 13 for the unallocated hall calls among the hall call registration signals from the hall call input means 12. Perform an evaluation operation. The bank with the best evaluation is output as the assigned bank for the registered hall call. Further, the allocation bank for the registered hall call is simultaneously output as the allocation bank for the hall.

The control command creating means 15 scans the assigned bank for the registered hall call to generate a response command signal, and scans the assigned bank for the hall to create an allocated floor signal. The control command output means 16 outputs these to each bank. After converting to the transmission format to, output to the transmission device. The elevator control means, which has received these signals via the transmission device, turns on the registration lamp of the hall call button having the response command signal by outputting a lighting command via the conversion device as described above. Then, the elevator control means responds to the hall call as described above, and when it responds, turns off the registration lamp. (Note that even if the elevator car responds, the bank which does not have a response command signal issues a registration lamp turning off command. No output). Further, the hall call input means 12 detects that the elevator car of the bank which issued the response command signal has responded from the elevator status information, and turns off the hall call registration signal.

The guide device 2 provided on each floor in FIG.
For the guide devices 24a to 24g of the corresponding banks 4a to 24g, the elevator control means creates a lighting instruction for the service hall indicated by the received allocated floor signal and the service hall peculiar to the bank, and outputs it through the converter. To display the service floor. The control command output means 16 outputs the lighting command created from the allocated floor signal by the control command creation means 15 to the guide device 25 of FIG. In addition, the service floor display in this automatic assignment performs the service floor display of the bank to which the response command signal is given each time a hall call is registered, so that the service bank always changes, and the passenger is provided with a hall call button. There is a disadvantage that the service bank cannot be known until the user presses it. However, since the banks can be allocated in consideration of the current elevator state or traffic state, it is possible to automatically and instantaneously control the balance of the traffic volume between the banks automatically. In addition, although the service bank is not known until the hall call button is pressed, the service floor display has the effect that it is not necessary to look at both banks until the elevator arrives.

For example, when the ascending call button on the 12th floor, which is the common landing of the first bank A, is pressed, if the assigned bank is 2, the ascending call button on the 12th floor of the second bank B is registered. The lamp is turned on, and the service floor display for the first bank A and the second bank B is as follows. First bank A ... B1, 1st to 9th floor Second bank B ... B1, 12, 14 to 20th floor

Here, the in-car call can be registered anywhere in the common hall. By the way, as a matter of course, there is no call button in the bank in the direction of exiting from the bank of the terminal hall as in the case of a call button on the 13th floor, even if it is a common hall. (For example, the up call button on the 13th floor is not installed in the bank 1) Further, the operation in FIG. 7 causes the allocation evaluation calculation means 14 to move only when the automatic allocation is selected.

Next, the hall call input means 12, the display control means 21, the CRT display device 22, the allocated floor registration means 1 of FIG.
7. A person who is realized in cooperation with the allocated floor search means 19, the calendar clock 20, the control command creating means 15, the control command output means 16, the allocated floor registration information 18, and the elevator control means (not shown). An operation of realizing floor allocation (register allocation) performed based on registered information will be described.

First, a description will be given of a process up to registration of an allocation bank as allocation floor registration information 18. The floor allocation screen shown in FIG. 7 is displayed by inputting an instruction from the light pen 3 on the elevator state monitoring screen shown in FIG. On the floor allocation screen, the current registration state is read from the allocated floor registration information 18, and the floor allocation state and the like are displayed. On this floor allocation screen, it is necessary to determine in advance the allocation of the common landing for each bank, that is, the registration of the allocation bank is performed in detail in the description of FIG. 7, but several modes can be registered. You can select and specify what you want to run regardless of time or what you want to run at a specified time. There is a problem of screen space in order to make all operations possible on the floor allocation screen of FIG. 7. When setting (reserving) time, the execution time setting screen of FIG. 8 is used. The display control means 21 and the allocated floor registration means 17 are responsible for executing these operations, and are finally stored in the memory as allocated floor registration information 18.

The allocated floor search means 19 constantly searches the allocated floor registration information 18, and first determines whether or not each registered mode can be executed, and selects a mode to be executed. Next, the allocation bank registered in the selected mode to be executed is read and output as the allocation bank for the landing. When the hall call registration signal from the hall call input means 12 is ON, the bank determined by the allocated bank for the output hall is output as the allocated bank for the registered hall call. In selecting a mode to be executed, a mode in which application shown in the floor allocation screen of FIG. 7 is “Yes” and a reservation is “No” is a mode to be executed regardless of time. If the reservation is “Yes”, it is assumed that the time is specified, and the reservation time is set to a mode in which only the valid one is executed in comparison with the calendar clock 20. When a plurality of modes to be executed are selected, the mode having the smaller mode number is set as the mode to be executed.

The control command creating means 15 creates a response command signal and an assigned floor signal from the assigned bank for the registered hall call output from the assigned floor search means 19 and the assigned bank for the hall, similarly to the automatic assignment. These control signals are transmitted to the elevator control means via the control command output means 16 and the transmission device, and perform the operation as described by automatic assignment.

The other steps are the same as those for the automatic assignment, such as the input of the hall button of the common hall, the registration processing of the hall call, the turning on / off of the registration lamp, the processing for responding to the common hall call, and the display processing of the guidance device. However, in the display on the guidance device, the floor to be allocated is determined in advance regardless of the registration of the hall call. The problem of "I don't know the bank" is gone,
A fixed service floor is always displayed until the contents of the registration change or the mode selection is changed. These can be performed systematically by time reservation or the like. However, since it is not possible to automatically perform the best control, it is necessary to register the traffic after each day of the week using a computer or the like.

Further, only when the automatic assignment is not selected by the operation in FIG. 7, the assigned floor search means 19 operates.

The outline of the operation has been described above.
Next, details of the means and the like cited in the above operations will be described with reference to FIGS.

First, the sequence of opening each screen in FIGS. 6 to 8 and the operation for opening each screen will be described with reference to the screen tree of FIG. 5 (which can be better understood by comparing with FIGS. 6 to 8).

An example will be described with reference to FIG. For example, when an erased character (hereinafter, a display portion such as a character selected by the light pen 3 is referred to as a column, for example, an erase column) is selected by the light pen 3 on the elevator state monitoring screen, the position signal is displayed on the CRT display device. 2 to display control means 2
The screen captured by the CPU 50a of the main controller 50 having the number 1 is erased (becomes an erased screen). When an arbitrary position is selected from the deletion screen, an elevator state monitoring screen is displayed. Further, when displaying the floor allocation screen from the elevator status monitoring screen, select the floor allocation column on the elevator status monitoring screen, and when displaying the execution time setting screen from the floor allocation screen, the floor allocation screen Select the mode name above and select the time setting field. In each screen, when the end column is selected, the screen returns to the previous screen.

In the columns of the third bank, the fifth bank to the seventh bank, the allocation floor registration information 18 read out from the allocation floor registration information table is displayed with a circle mark (the details are omitted because they are as shown in the guidance of 74 in the figure). Note that, as described in the guidance 74, the allocation banks are the first to third bank groups and the fifth to seventh bank groups.
It is assumed that each bank group registers independently (in this building, these two groups are separated from each other as described above). The one currently displayed in the floor allocation column is the content of mode 2, which corresponds to the one described above as the allocation landing example 1. Reference numeral 78 denotes a mode name column. As shown in the name column in the column, eight modes from mode 1 to mode 8 can be registered. There is an application column and a reservation column corresponding to each mode, the application column is a column to specify whether the registered mode is actually applied, and the reservation column is not always applied, but is applied only during the specified time (Specification is not applied, and the application time setting field is selected following the specification, and is set on the execution time setting screen in FIG. 8 described later).

The state being modified is displayed (the setting state of each hour / minute column performed based on the operation shown in the guidance 84 is temporarily stored in the memory and displayed). If the end column 87 is selected without selecting the setting column 86, the registration is not performed, and the original execution time remains the content of the allocated floor registration information table.

Next, a description will be given of the configuration of a program as a means for realizing each of these functions, and a program procedure for executing the program.

FIG. 9 is a flowchart showing a startup program in the CPU of the main control unit of the elevator multi-group control unit according to one embodiment of the present invention. This program is executed first when the power is turned on or when the system is reset, and is executed only once when the power is turned on or after the reset. By executing this program, hardware initialization, activation of some tasks that are always executed, and activation of the scheduler shown in FIG. 10 are performed. Each task started here enters the management of the scheduler after the startup program ends, and is processed in parallel with other tasks.

Referring to FIG. 9, first, in step S1, a main controller internal device initialization routine is called and executed. In this initial setting routine, initial clear of RAM,
It sets peripheral LSIs and hardware, and sets initial values of data necessary for other programs. Since these are realized by ordinary computer technology and have little relation to the content of the present invention, they will not be described in further detail here (the same applies to the following). In step S2, the task for transmitting the CRT display device is started, and in step S3, the CRT display device is initialized. That is, a task for transmitting a CRT display device for transmitting data to and from the CRT display device 2 is started, and after communication is established, initial setting of operation specifications of the CRT display device 2 and registration of display data are performed. In step S4, the task for printer transmission is started, and in step S4
In step 5, the printer is initialized. That is, a printer transmission task for performing transmission with the printer 9 is started,
After the communication is established, initial settings of the operation specifications of the printer 9 and registration of display data are performed. In step S6, a printer output data creation task is started. This printer output data creation task creates data for printing and recording the occurrence of a failure or disaster, and passes the created data to the printer transmission task.
In step S7, an external device data input / output task is started. That is, an external device data input / output task for inputting a contact signal with the external device and outputting a designated signal is started. The external device is a guiding device or a monitoring panel device connected to the multi-group control device. In addition, the guidance device executes the display according to the allocated floor signal output from this task. For details of the internal operation of the guide device, for normal technology,
Here, the description is omitted. In step S8, an external device input / output data creation task is started. This external device input / output data creation task creates command signals to the monitoring panel devices such as guidance devices and alarm signals, passes them to the external device data input / output task, and also outputs contact signals from external devices to external device data input / output. Receive from task and convert to program readable form. In step S9, the task for elevator transmission is started. By activating the elevator transmission task for performing transmission between the first to seventh banks, communication with the elevator is started. In step S10, a task for creating an elevator state signal starts. The elevator status signal creation task receives the elevator status signal received from the first to seventh banks by the elevator transmission task from the elevator transmission task, and converts it into a format that can be read by another program. This signal includes the car position,
There are a car direction, a car load, a bank-specific registered hall call, a hall call assignment for each car, an intra-car call, and the like. In step S11, a task for creating an elevator control command output signal is started.
The elevator control command output signal creation task converts the control command signal created by the scheduler into a format to be transmitted to the elevator and passes it to the elevator transmission task (details are shown in FIG. 11). In step S12, the scheduler is started. That is, a scheduler for starting a necessary processing program when necessary is started (details are shown in FIG. 10).

By executing such a series of startup programs, initialization of hardware, startup of some tasks that are always executed, and startup of the scheduler shown in FIG. 10 are performed. Each task started here enters the management of the scheduler after the startup program ends, and is processed in parallel with other tasks. Steps S2 and S
Each of the transmission tasks in step 4 and step S9 is a program that plays a role usually called a driver, and controls a serial I / O element for transmission to a partner device via a serial I / O element such as an Intel 8251. And control the communication procedure. The protocol is a BASIC procedure. Further, the tasks of step S6, step S8, step S10, and step S11 usually perform data format conversion and fixed signal processing in data transmission / reception between a driver called a handler and an application program.
FIG. 11 shows a detailed procedure for the task for generating an elevator control command output signal in step S11.

FIG. 10 is a flowchart showing a program of a scheduler for managing activation of each task in the CPU of the main control unit of the elevator multi-group control unit according to one embodiment of the present invention. All programs executed by the CPU are managed by this scheduler. This scheduler is started periodically, for example, once every 0.1 second, by interruption by a timer. Note that the task started by the start program and the task started by the scheduler are sequentially allocated with a short time (slice time) for execution, and apparently executed in parallel at the same time. In addition, details such as task management and program startup management using a timer can be configured by using a normal technique in an operating system, and a description thereof will be omitted.

Further, since each screen task and other tasks are executed in parallel, display and control execution by the processing of these tasks are executed in parallel in real time (for example, by opening the elevator status monitoring screen). However, the execution of the control such as the output of the response command signal to the hall call is performed simultaneously). The operation control execution task and the operation control screen task are for performing the operation control of the elevator as a part of the elevator monitoring function. Since these have little direct relation to the present invention, detailed description will be omitted.

Referring to FIG. 10, first, in step S21, a process of registering a common call and canceling registration is performed. That is, in each of the two groups of the first to third banks and the fifth to seventh banks, the common hall call button signals from all the banks are scanned, and O
The hall call registration signal for the floor and direction of N is turned ON. The hall call registration signal is provided for each of the first to third banks and the fifth to seventh banks. Then, when one of the banks of the bank outputting the response command signal in the direction and the floor where the response command signal is ON stops in the same direction on that floor, the corresponding floor and direction of the responding group Turn off the hall call registration signal. In step S22, it is determined whether or not the automatic allocation column is released from selection. If the automatic allocation column is released from selection, the floor search task is started in step S23, and the allocation evaluation calculation task is started in step S24. Ends, and the process proceeds to step S25. If it is determined in step S22 that the selection of the automatic assignment field is not canceled, the process directly proceeds to step S25. As described above, when the automatic allocation selection flag created by the floor allocation screen task is changed from ON to OFF, that is, when the automatic allocation is released and the selection is no longer being performed, it is determined that the registered allocation has been made. Activate the floor search task and end the assignment evaluation calculation task at the same time. Immediately after the system is started, the automatic allocation selection flag is changed from ON to OFF and the processing is performed. Details of the allocated floor search task are shown in FIG. 16, and details of the allocated evaluation calculation task are shown in FIG. In step S25, it is determined whether or not the automatic allocation column has been selected. If the automatic allocation column has been selected, the allocated floor search task ends in step S26, and the flow proceeds to step S27.
Starts the assignment evaluation calculation task, and proceeds to step S28. If it is determined in step S25 that the automatic assignment field is not being selected, the process directly proceeds to step S28.
Here, when the automatic allocation selection flag created by the floor allocation screen task changes from OFF to ON, that is, when the automatic allocation release operation is performed and the automatic allocation selection is being performed, the automatic allocation is determined to have been performed. Activate the floor calculation task and end the allocated floor search task at the same time. In step S28, it is determined whether or not the operation control execution task has not been started. If not, the operation control execution task is started in step S29, and the process proceeds to step S30. If it is determined in step S28 that the operation control execution task has been activated, the process directly proceeds to step S30. Thus, an operation control execution task for creating an elevator control command is started based on the operation control information set on the operation control screen.
This task does not end once it is started. Thereafter, the screen tasks are activated and terminated in steps S30 to S33. That is, step S30
Starts and ends the elevator status monitoring screen task, starts and ends the floor assignment screen task in step S31, starts and ends the execution time setting screen task in step S32, and operates the operation control screen task in step S33. Start up and shut down. Steps S30 to S33 are programs for starting and ending a task for performing data processing and display processing for each screen corresponding to an operation on each screen, and a detailed procedure will be described in each of the drawings described later. Details of the elevator status monitoring screen task are shown in FIG. The procedure for activating and ending the other screen tasks may be configured in accordance with the screen tree of FIG. The details of the floor assignment screen task are shown in FIG. 14, and the details of the execution time setting screen task are shown in FIG.

FIG. 11 is a flowchart showing details of an elevator control command output signal creation task of the elevator multi-group control apparatus according to one embodiment of the present invention. This task is based on the allocation bank data for the registered hall call of the common hall and the data of the allocation bank for the common hall created by the allocation floor search task and the allocation evaluation calculation task, and responds in a signal format used by the elevator control means. Create signals and assigned floor signals. Further, although not directly related to the present invention, the operation control execution task for operation control of the elevator converts the operation control command created into a signal format used by the elevator control means. These signals generated by conversion or the like are further converted into a form conforming to the transmission protocol, and then written into the reception area of the task for elevator transmission.

In FIG. 11, in step S41, an allocation bank for a registered call of a common hall is read out, and step S4 is executed.
This is converted into a response command signal as an elevator signal in 2. That is, a response command signal corresponding to each bank is generated in a signal format used by the elevator control means based on the allocated bank data for the registered hall call of the common hall created by the allocation floor search task and the allocation evaluation calculation task. At this time, the signal of the position corresponding to the floor and direction of the registered hall call of the response command signal of the bank to which the registered hall call is allocated is turned ON, and the signal of the position to which the bank is not allocated is O.
FF. These processes are performed for the registered hall calls of each of the two groups of the first to third banks and the fifth to seventh banks. Next, in step S43, an allocation bank for the common hall is read out, and in step S44, this is converted into an allocation floor signal as an elevator signal. Similarly to the above, based on the allocated bank data for the common hall created by the allocated floor search task and the allocated evaluation calculation task, the allocated floor signal corresponding to each bank in the signal format used by the elevator control means. Create At this time, the signal at the position corresponding to the floor and direction of the assigned floor signal of the registered bank is turned ON, and the signal at the position where the bank is not allocated is turned OFF. These processes are performed in the first to third banks and the fifth bank to
This is performed for the common landing of each of the two groups in the seventh bank. Then, in step S45, the operation control execution task reads the created operation control instruction, and in step S46, converts the operation control instruction signal into an elevator signal. In this way, the operation control command signal created by the operation control execution task is converted into a signal format used by the elevator control means in association with each bank. Thereafter, in step S47, all commands are written in the reception area of the task for elevator transmission,
Again, the process returns to step S41, and the above series of procedures is repeated. Here, the response command signal, the allocated floor signal, and the operation control command signal are converted into a form (transmission format) conforming to the transmission protocol, and are associated with the communication channels of each bank, and written in the reception area of the task for elevator transmission. Put in. Thereafter, the elevator transmission task sequentially outputs to the communication channel corresponding to each bank. The details of the elevator transmission task are not shown.

FIG. 12 is a program for starting and ending an elevator status monitoring screen task for performing data processing and display processing corresponding to an operation on the elevator status monitoring screen of the elevator multi-group control device according to one embodiment of the present invention. 6 is a flowchart showing details of the process. The elevator state monitoring screen task is also activated when the floor assignment screen task and the operation control screen task are closed.

In FIG. 12, it is determined in step S51 whether or not something has been input on the delete screen. If something has been input, the delete screen task is terminated in step S52, and the elevator status monitor screen is displayed in step S53. Activate the task and proceed to step S54. If it is determined in step S51 that nothing has been input, the process proceeds directly to step S54. As described above, when the screen is being erased, that is, while the erase screen task is being executed, when a position selection reception signal by the light pen is received from the CRT display device transmission task, the erase screen task is closed and the elevator state monitoring is performed. Start a screen task. In step S54,
It is determined whether or not the delete column is selected on the elevator status monitoring screen. If the delete column is selected, step S55 is performed.
To end the elevator status monitoring screen task, and
At 56, the erase screen task is started, and the routine based on this program ends. If it is determined in step S54 that the erasure column has not been selected, the routine according to this program is terminated. Thus, when the reception signal of the selection of the erasure column by the light pen is received from the task for transmitting the CRT display device during the execution of the elevator status monitoring screen task, the elevator status monitoring screen task is closed and the erasure screen task is activated.

The erase screen task is for keeping the screen in an erased state, and nothing is executed as actual task processing. That is, it is a non-executed task. The erasing screen task is activated only when the erasing column is selected on the elevator status monitoring screen shown here and when the system is started at power-on. Also, it is closed by activating the elevator status monitoring screen task.

FIG. 13 is a flowchart showing details of an elevator status monitoring screen task for performing data processing and display processing corresponding to operations on the elevator status monitoring screen of the elevator multi-group control apparatus according to one embodiment of the present invention. is there.

In FIG. 13, the screen is cleared at step S61, and the fixed portion is displayed at step S62. To make the screen blank once,
A screen erase command is output to the T display device. Then, to display the unchanged part of the elevator status monitoring screen,
Read the display data for the elevator status monitoring screen from the fixed part display data table fixed in the ROM in advance,
Output to CRT display. Thus, the title name 61, the screen switching columns 63a to 63c, the bank name 66, and the like in FIG. 6 are displayed. In addition, including the following description, the display data referred to here is a group of commands that can be interpreted by a CRT display device, and is a collection of commands for displaying characters and commands for displaying graphics. Then, in step S63, the current elevator status signal is received, the time is read, and in step S64, the initial display of the changing portion is performed. That is, the current elevator status signal is received from the elevator status signal creation task, the display data of the changing portion corresponding to the elevator status signal is read from the changing portion display data table set in the ROM in advance, and output to the CRT display device. To perform initial display. Thus, the bank frames 64a to 64g, the unit frames 65a to 65d, the disaster occurrence status 67, and the like in FIG. 6 are displayed.
Further, the current date and time are read from the clock, the display data of the time is read in the same manner, and output to the CRT display device to perform the initial display of the time. Thus, the current time 62 in FIG. 6 is displayed. Next, in step S65, it is determined whether there is a change in the elevator status signal or the time. If there is a change, the display of the changed portion is updated in step S66, and the process proceeds to step S67. If it is determined in step S65 that the elevator status signal or the time has not changed,
Proceed directly to step S67. In this way, the current elevator status signal is received from the elevator status signal creation task, and only the status signal that has changed from the previous status signal is extracted, and the same as the above-described initial display of the changing portion, corresponding to the changing portion on the screen. Only display data is output to the CRT display device. At this time, the display data for erasing the portion to be newly rewritten is input first, and then the new display data is output so as not to overlap. The same applies to the update of the time display. In step S67, it is determined whether or not the field for screen switching has been selected. If the field has been selected, the name of the selected field is passed to the scheduler in step S68, and the routine according to this program ends as it is. If it is determined in step S67 that the screen switching field has not been selected, the process returns to step S65. As described above, when a received signal is received from the task for transmitting the CRT display device by selecting the position of the light pen 3 in any one of the erasure column 63a, the floor allocation column 63b, and the operation control column 63c, the scheduler names the selection column. And ends the processing. The task end processing is performed by the scheduler.

FIG. 14 is a flowchart showing the details of a floor assignment screen task for performing data processing and display processing corresponding to operations on the floor assignment screen of the elevator multi-group control apparatus according to one embodiment of the present invention. is there. The above procedure will be briefly described.

In FIG. 14, the screen is cleared in step S71, the fixed portion is displayed, and the initial display of the time changing portion is performed. First, a screen clear, a fixed part display, and a time change part initial display are performed. Thus, the title name 7 in FIG.
1. Screen switching columns 73a and 73b, guidance display column 7
4. Cancellation column 76, floor allocation column 77, and mode name column 78
Is displayed. Further, the current state of the changing part is displayed. The changing part initial display is performed for the time of the current time 72, the reservation field and the application field of the mode name field 78 (read and displayed for each mode from the allocated floor registration information table). Then, the time display is updated in step S72. In step S73, it is determined whether or not a mode name has been selected. If the mode name has been selected, a mode name display field and a floor allocation field are switched and displayed in step S74.
Go to 5. If it is determined in step S73 that the mode name has not been selected, the process proceeds to step S75.
Proceed to. As described above, when a position selection signal of the position of the light pen 3 in the name column in the mode name column 78 is received, the mode name corresponding to the selected position is stored as the selected mode, and the name corresponding to this mode is set to the mode name. Switch the display to the display column. At the same time, the allocation bank data of the common hall corresponding to the mode name is read from the allocation floor registration information table, and the display of the floor allocation column 77 is switched. In step S75, it is determined whether or not the floor allocation column is selected during the mode name selection. If it is selected, the allocation registration is updated and the display of the floor allocation column is updated in step S76. S7
Go to 7. If it is determined in step S75 that the floor assignment column has not been selected during the mode name selection, the flow directly proceeds to step S77. As described above, when a selection signal of any of the floor allocation columns 77 is received, the contents of the allocated floor of the bank corresponding to the selected position and the direction corresponding to the selected position in the selected mode are assigned to the allocated floor registration information. Invert the contents read from the table and write. That is, if "O", leave blank, if blank, set "O" and re-register. At the same time, the display in the floor allocation column 77 is switched to the new content. Step S7
At 7, it is determined whether or not the reservation column has been selected. If the reservation column has been selected, the update of the reservation presence / absence registration and the display of the reservation column are updated in step S78, and the process proceeds to step S79. If it is determined in step S77 that the reservation column has not been selected, the process directly proceeds to step S79. Here, when a selection signal of any of the reservation columns is received, the reservation contents of the corresponding mode are read from the allocated floor registration information table, and the contents are inverted and written. In other words, if "Yes", "No",
If "No", set to "Yes" and re-register. At the same time, the display of the reservation column is switched to the new content. In a step S79, it is determined whether or not the application column is selected. When the application column is selected, the update of the application presence / absence registration and the display of the application column are updated in a step S80, and the process proceeds to a step S81. Step S
If it is determined at 79 that the application field has not been selected,
Proceed directly to step S81. Here, when a selection signal of any of the application columns is received, the application contents of the corresponding mode are read from the allocated floor registration information table, and the contents are inverted and written. That is, if "Yes", "No"; if "No", "Yes" and re-register. At the same time, the display of the application column is switched to the new content. In a step S81, it is determined whether or not the automatic allocation column is selected. If the automatic allocation column is selected, the flag and the display are updated in a step S82, and the process proceeds to a step S83. If it is determined in step S81 that the automatic assignment field has not been selected, the process directly proceeds to step S83. Here, when the selection signal of the automatic allocation column 79 is received, the automatic allocation flag is read out, the contents are inverted and then written. That is, if "ON", "OFF", if "OFF", "ON" and rewrite. When the flag corresponds to "ON", the background color of the automatic allocation column 79 is displayed as "automatic allocation selected". In step S83, it is determined whether or not the cancel column has been selected. If it has been selected, the selection is canceled in step S84, and the process proceeds to step S85. If it is determined in step S83 that the cancel column has not been selected, the process directly proceeds to step S85. Here, when the selection signal of the cancellation column 76 is received, the selected mode is cleared. Further, the mode name display column 78 and the floor allocation column 77 are deleted. In step S85, it is determined whether or not the screen switching field is selected and the switching is valid.
If the screen switching field is selected and the switching is valid,
In step S86, the name of the selection field is passed to the scheduler,
The routine based on this program is finished as it is. If it is determined in step S85 that the field for screen switching is not selected, or if it is determined that switching is not valid, the process returns to step S72. in this way,
When receiving a selection signal of either the end column or the time setting column, the name of the selection column is passed to the scheduler, and the process is terminated. The task end processing is performed by the scheduler. When the time setting field is selected, the screen is not switched unless the mode name is selected and stored. When the screen is switched by the time setting column, the mode name is also passed to the scheduler.

FIG. 15 is a flowchart showing details of an execution time setting screen task for performing data processing and display processing corresponding to an operation on the execution time setting screen of the elevator multi-group control device according to one embodiment of the present invention. is there. The description of the above-described procedure will be simplified.

In FIG. 15, the screen is cleared in step S91, the fixed portion is displayed, the time change portion is initially displayed, and the mode name and the time setting state are displayed in step S92. That is, in step S91, as described above,
Screen clear, fixed part display, and time change part initial display are performed. Thus, the title name 81 and the screen switching column 8 in FIG.
3, guidance display field 84, setting field 86, cancellation field 87,
A number column 88 and a part of the start / end time setting column 89 are displayed. In step S92, the mode name passed from the scheduler is displayed in the mode name display column. The registration time corresponding to the mode name is read from the allocated floor registration information table and displayed in the start / end time setting column 89. The read time is also stored in the temporary memory. Then, the display of the time is updated in step S93, and it is determined whether or not the hour / minute column is selected in step S94. If the hour / minute column is selected, the input column is updated in step S95. Proceed to step S96. If it is determined in step S94 that the hour / minute column has not been selected, the process proceeds to step S94.
Go to 96. In this way, the selected hour / minute column for each start / end time is stored as being input, and at the same time, the temporary memory corresponding to the selected hour / minute column is cleared. Step S
At 96, it is determined whether or not the number field has been selected. If the number field has been selected, the setting state is updated in step S97, and the process proceeds to step S98. Step S
If it is determined at 96 that the number field has not been selected,
Proceed directly to step S98. That is, when the selection signal of the number column 88 is received, the hour / minute column 8 is being input.
The number corresponding to the selected signal position is stored in the lower two digits of the two digits of the temporary memory corresponding to No. 2. Next, the previous lower digit is stored as the upper digit. Then, the contents of the temporary memory are displayed and updated in the corresponding start / end time setting column 89.
In step S98, it is determined whether or not the cancel field is selected. If the cancel field is selected, the selection is canceled in step S99, and the process proceeds to step S100. If it is determined in step S98 that the cancel column has not been selected, the process proceeds directly to step S100. That is, as described above, when the selection signal in the cancel column 76 is received, the hour / minute column 82 stored as being input is canceled. Step S100
Then, it is determined whether or not the setting field has been selected. If the setting field has been selected, this is registered in step S101,
Proceed to step S102. If it is determined in step S100 that the setting field has not been selected, the process proceeds directly to step S102. Here, when the selection signal of the setting column 86 is received, the contents of the temporary memory are written in the allocated floor registration information table at the position corresponding to the mode passed from the scheduler. In step S102, it is determined whether or not the end field has been selected. If the end field has been selected, the name of the selected field is passed to the scheduler in step S103, and the routine according to this program ends as it is. If it is determined in step S102 that the end field has not been selected, the process returns to step S93.
Thus, when the selection signal of the end column 83 is received, the name of the end column is passed to the scheduler, and the process ends. The task end processing is performed by the scheduler.

FIG. 16 is a diagram showing an embodiment of the present invention, which is called by the scheduler of the elevator multi-group control device, and the floor allocation screen task creates the allocated floor registration information table, the calendar clock and the registered hall call signal. It is a flowchart which shows the detail of the allocation floor search task which creates the data of the allocation bank with respect to a common hall, and the data of the allocation bank with respect to the registered hall call of a common hall.

In FIG. 16, first, at step S111
Use to determine the application mode. Here, the application contents for each mode are sequentially read from mode 1 from the allocated floor registration information table. If the application content is "No", proceed to the next mode, "Yes"
At this time, the reserved contents of the mode are read. If the reservation content is "none", the mode during scanning is determined as the application mode. When the reservation content is "present", the registration time of the mode is read. If the current time read from the calendar clock 20 is within the registered time, the mode being scanned is determined as the applicable mode,
If it is not within the registration time, the process proceeds to the next mode. If the application mode cannot be determined by scanning all the modes, the application mode is set to none. If there is no applicable mode, this process ends. In step S112, it is determined whether or not the application mode exists. If the application mode exists, an allocation bank for the common hall is created in step S113, and an allocation bank for the registered hall call of the common hall is created in step S114. Then, the routine based on this program ends. If it is determined in step S112 that the application mode does not exist, the routine based on this program ends. That is, when the applicable mode exists, the assigned floor contents of the applied mode are read from the assigned floor registration information table, and the bank name corresponding to the bank marked “○” is assigned to each floor and each direction. . This allocation result is stored in the memory as allocation bank data for the common landing. If there are multiple, the first bank,
If there is no bank marked "O", leave it blank. These processes are divided into two groups, a first bank to a third bank and a fifth bank to a seventh bank, and each has data to be performed for a common landing of each group. Then, a common hall allocation bank corresponding to the floor and direction for which the hall call registration signal from the scheduler is ON is allocated. This allocation result is stored in the memory as allocation bank data for the registered hall call of the common hall. If no common hall allocation bank is registered, the allocation to the registered hall call is not performed. These processes are divided into two groups, a first bank to a third bank and a fifth bank to a seventh bank, and have data to be performed for registered hall calls of each group.
Here, the common hall allocation banks corresponding to the registered hall calls correspond to those of the same group.

FIG. 17 shows an allocation which is called by the scheduler of the elevator multi-group control device according to one embodiment of the present invention, and which generates the data of the allocation bank for the common hall and the data of the allocation bank for the registered hall call of the common hall. It is a flowchart which shows the detail of an evaluation calculation task. Here, for one of the registered hall calls, a bank that can be commonly served is temporarily allocated to calculate an allocation evaluation value, and the bank with the best evaluation value is set as the allocation bank. Although the maximum number of banks to be allocated is supposed to be two at the maximum, it is not necessary to limit the number of banks when considering other embodiments. it can.

In FIG. 17, it is determined in step S121 whether there is a registered hall call in the common hall. In step S122, it is determined whether there is an unallocated hall call. If it is determined that there is no registered hall call in the common hall, or If it is determined that there is no allocated hall call, the routine according to this program is terminated. If there is a registered hall call of the common hall and an unallocated hall call, one of the unallocated hall calls is selected in step S123. That is, one of the unassigned hall calls is randomly selected from the registered hall calls of the common hall of each of the two groups of the first to third banks and the fifth to seventh banks, and the selected one is selected as the hall. The call gh is set in the temporary memory. Here, g indicates a group, and when g = 1, a series of the first to third banks is indicated, and when g = 2, a series of the fifth to seventh banks is indicated. H represents the floor and direction of the common landing. Step S12
At 4, a bank that can service the hall call gh is selected. That is, a bank that can service the hall call gh is read from the specification data and set as b1 and b2. In addition,
In this building, the maximum number of banks that can serve in common is two. In step S125, bank b for hall call gh
Calculate the allocation evaluation values of 1 and b2. Here, it is assumed that each of the banks b1 and b2 is provisionally allocated to the selected unallocated hall call gh, and the allocated evaluation value e1 (bank b
1) Find e2 (bank b2). The details are shown in FIG. 18 described later. In step S126, the bank which minimizes the allocation evaluation value is set to b, and in step S127, b is set as the allocation bank for the registered hall call h of the g group. In step S128, b is set to the common hall h of the g group.
And the routine according to this program ends. That is, the smaller of the allocation evaluation values e1 and e2 is determined as the allocation bank, and the bank is set as b. Then, the bank b is determined to be the bank assigned to the registered hall call h of the group g, and stored in the memory as the allocated bank data for the registered hall call of the common hall. Further, the bank b is determined to be the bank assigned to the common hall h of the g group, and is stored in the memory as the bank data assigned to the common hall.

FIG. 18 is a flowchart showing the details of the allocation evaluation calculation routine, which is a routine called from the allocation evaluation calculation task of the elevator multi-group control apparatus according to one embodiment of the present invention. This is to temporarily assign each of the banks b1 and b2 to the common hall call gh given by the assignment evaluation calculation task, and to obtain an assignment evaluation value in that case. In each assigned bank, the hall call h is further temporarily assigned to each of the cars in the bank, and an assignment evaluation value for each of the cars is calculated. And the minimum assigned evaluation value (the smaller the better, because it is the value that leads to the waiting time)
Is the allocation evaluation value of the bank.

In FIG. 18, first, at step S131
Calculates the allocation evaluation value of all the units in the bank b1, calculates the minimum allocation evaluation value in step S132, and calculates the minimum allocation evaluation value in step S13.
At 3, the minimum allocation evaluation value is set as the allocation evaluation value e1 of the bank b1. That is, for all the cars in the bank b1, the evaluation value (assignment evaluation value) for each car when the hall call h is temporarily assigned is obtained using a predetermined assignment evaluation function. Then, the smallest one of the allocation evaluation values of all the units in the bank b1 is taken out, and the taken out minimum allocation evaluation value is set as the allocation evaluation value e1 of the bank b1.

Here, an example of the assignment evaluation function will be described. This is best when the sum of all waiting times in the bank is minimized. Hn = Th + Σi (Wi + Ti) Hn ... Evaluation evaluation value of car n Th: Hall call h when provisional call h is assigned to car n
Estimated arrival time at Wi Wi: expected waiting time of assigned hall call i Ti: Estimated arrival time of assigned car at assigned hall call i Note that car n is the value at the time of provisional assignment, (Wi + T
i) is a value obtained by adding the continuous waiting time and the estimated arrival time of the assigned car, and is referred to as the expected waiting time.

Next, in step S134, the allocation evaluation value of all the units in the bank b2 is calculated, in step S135 the minimum allocation evaluation value is calculated, and in step S136, the minimum allocation evaluation value is set as the allocation evaluation value e2 of the bank b2. Set. That is, similarly to the bank b1, the allocation evaluation value for the hall call h is obtained for all the units in the bank b2, the smallest one of the allocation evaluation values for all the units in the bank b2 is taken out, and the taken out minimum allocation evaluation value is taken as This is set as the allocation evaluation value e2 of the bank b2.

Note that the assignment evaluation items include evaluation factors other than the waiting time, and the evaluation method need not be limited to this, such as evaluating the square of the waiting time. In addition, the allocation evaluation value was evaluated based on the current status information, but a program procedure for detecting services between banks from statistical data obtained through online collection was provided, and allocation was performed so that services were equalized among banks. It is also possible to determine the bank. In other words, the bank to be allocated in the future is determined from the past service status. In this case, the service bank is fixed for a certain period of time, so that the service bank does not change all the time and the service bank is easily found. .

FIG. 19 is a flowchart showing a procedure of a process for responding to a hall call in the elevator control means of the elevator multi-group control apparatus according to one embodiment of the present invention. The procedure for starting the program of the elevator control means, the configuration of the transmission task, and the like can be easily realized by configuring based on the technique described in the multi-group control device, and thus the description is omitted. This routine is repeatedly called from the scheduler and executed. In addition, when the landing button is pressed, it is not performed in this routine to send it as a landing button signal to the acquisition multi-group control device, but is executed by another task (not shown).

In this routine, the best car to be assigned to the registered hall call, which is a combination of the registered hall call indicated by the response command signal from the multi-group control device and the registered hall call unique to the bank, is determined based on the evaluation value. Make the unit respond. When the response command signal is received, the registration lamp of the hall button is turned on. The common hall call to which the car is assigned responds in the same manner as for conventional, ie, bank-specific, registered hall calls. When the elevator car responds to the common hall call, the registration lamp of the hall button is turned off on the condition that the elevator car has received the response command signal.

Further, the service hall indicated by the allocated floor signal from the multi-group control device and the service hall unique to the bank are combined to form a service hall (in the case of performing either ascending or descending service, the service floor is referred to as the service hall). The service floor is sequentially obtained from the lowest floor to obtain a service floor, a display command is created based on the service floor (continuous floors are displayed continuously), and output to the guidance device for display.

In FIG. 19, in step S141, registration cancellation of a hall call and extinguishing of a registration lamp are performed. That is, for a registered hall call unique to the bank, when the assigned car stops on the floor, the registration of the registered hall call in the car direction on the car position floor is canceled, and a command to turn off the registration lamp is output. For a common hall call, when the assigned car stops at the floor, if the corresponding response command signal is ON, a turn-off command for the registration lamp in the car direction on the car position floor is output. In step S142,
Register the hall call and turn on the registration lamp. That is, for the hall call unique to the bank, the hall call registration signal for the floor and direction in which the hall button signal is turned on is registered as ON, and at the same time, a registration lamp lighting instruction is output.
