Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a group management control system for elevators, and particularly to improvements in a call assignment method and a guidance control method.

[Conventional technology]

Conventionally, elevator calls have been assigned by calculating an evaluation value for each car and allocating the generated calls to a single elevator with the optimum evaluation value. Recently, the traffic flow within a building has been learned and simulated to determine optimal call allocation parameters. However, although elevators controlled in this way can minimize the average waiting time for the entire building, when looking at individual calls, it does not necessarily select the elevator that can arrive in the shortest waiting time. Therefore, after the customer has delivered the product, there may be a request to allocate an elevator that can arrive at a specific floor or at a specific time with the shortest waiting time. Also, on a particular floor, a request may be made to allocate an empty elevator for carrying luggage even if the waiting time is long.

[Problem that the invention seeks to solve]

As a way to deal with such changes in specifications after delivery,
JP-A-59-31266 and JP-A-59-48364 disclose a function for reserving an event.

However, with this method, it was only possible to select a coping method suited to the situation from processing methods for conditions assumed in advance. Customer requirements vary.

Currently, in the case of an unexpected request, the maintenance company or manufacturer responds by changing the program or evaluation formula. However, changing programs and evaluation formulas to satisfy customer requests can reduce overall efficiency, and it takes a lot of time to verify that the changes are correct. It took a long time to complete the program, making it impossible to respond to customers in a timely manner.

Additionally, there may be requests for special guidance only on specific floors or at specific times.

In particular, in recent years, guidance has come to be displayed using text and graphics, resulting in numerous changes in specifications after delivery. For example, if you reserve a call and use the display method to notify you that there will be a long wait for that call, please wait for a while. ’ or use the waiting time to display product commercials.

(Problems to be Solved by the Invention) The above-mentioned problems arise because there is no way for manufacturers to easily respond to unexpected customer demands.

An object of the present invention is to enable the customer to change only the customer request section of the elevator call assignment system and guidance system in response to customer requests that are not expected by the manufacturer.

[Means for solving problems]

In order to achieve the above objective, for call allocation, we will install a device that inputs the conditions for the occurrence of a landing call and the allocation method when those conditions are met, and the input contents will be memorized so that the conditions entered above will match when a landing call occurs. This can be accomplished by configuring the system to allocate calls according to the input allocation method, and when they do not match, to allocate calls according to a predetermined evaluation formula. In addition, regarding guidance control, a device is provided for inputting a predetermined condition and a guidance method under the condition, the input contents are memorized, and when a condition matching the input condition occurs, the input guidance method is used. This can be achieved by providing guidance and, if they do not match, issuing a guidance notification according to a predetermined guidance method.

The specific means is communication with the elevator control device, or
There is a separate processing device for changing specifications that is connected to a storage medium, and this processing device has an input device for customers to change specifications and input conditions that can be executed by the elevator control device according to a predetermined procedure. This is achieved by preparing means for converting the converted content and means for storing the converted content, and controlling as described below. (This kind of processing device is generally called an AI tool, so it will be expressed as an AI tool in the following explanation.) The specification change content input by this AI tool is divided into a condition part and an execution part for controlling. is stored as a so-called rule, and its contents are transmitted to the elevator control device. The condition part of this rule is classified by event, such as when a hall call occurs, when a guidance display is displayed, or when a specific switch is operated. Upon receipt of this, the elevator control device determines whether or not a rule regarding the event has been registered when one event occurs, and if so, determines whether the condition part matches. If there is a match, the processing recorded in the execution section is performed. If they do not match, other rules are sequentially determined, and if none of the rules match, predetermined control is performed.

[Operation] An example of the operation of the elevator control device configured as described above will be explained. Assume that there is a request from a customer to allocate an empty car to the fifth-floor up call between 10:00 and 11:00. At this time, the customer follows the guidance of the AI tool and inputs the result, and the result is registered in the event when the hall call occurs, and the condition part is the first judgment part of 5th floor up call and 10 o'clock to 11 o'clock. It is decomposed into a second judgment part, and a control law called an AND condition of these two judgment parts is added. And in the execution part, the load inside the basket is 3
The content that an assigned elevator is selected from 0% or less of elevators is registered. This AI tool determines what percentage of the car load an empty car means, and if there are no empty cars at that time, does it control so that an empty car is created, or does it call the most empty car at that time? In order to interpret the content into something that can be executed by an elevator control device such as a computer, the necessary questions are displayed on the display, responses are requested, and the conditions are organized by repeating the process. Furthermore, the AI tool can point out any unreasonableness with the already registered conditions, and can also infer that problems that occur when the customer's requests are directly adopted, for example, the average waiting time will worsen by 50% or more. If so, display it.

The rules registered in this way are transmitted to the elevator control device. Each time a hall call occurs, the elevator control device determines whether or not it matches a registered event, and if it is an up-call for the fifth floor that occurs between 10:00 and 11:00, it is determined that the car has a car load of 30% or less. If the 0 condition for selecting the optimal elevator is not met, for example,
If it is a call on the 6th floor, the call is assigned according to the evaluation formula.By controlling in this way, the required functions can be easily realized without changing the entire system.

〔Example〕

An embodiment of the present invention will be described using FIGS. 1 to 9.

FIG. 1 is an overall configuration diagram of the hardware of the present invention.

The elevator control system fll is composed of a group management control device 10 and each machine control device 20 to 22, and its construction method is a known microcomputer control method.The input of the first group management control device is a hall call registration device for each floor. There are signals from 11 and the building management device i12, and the output is the voice guidance system at the platform! ! 13 and the signals of the display device 14 at the platform 6
The car control device controls the travel and doors of cars 30 to 32 of each elevator, and controls the car's in-car annunciator 15 such as an in-car display and an in-car voice guidance device, as well as hall lanterns, chimes, etc. for each car. Controls the alarm 16. The AI tool 2 is connected to the group management control device using a communication line 6.

This connection method is not limited to the method of connecting via a communication line, but other methods such as connecting via a storage medium may also be used.This AI tool is a generally commercially available workstation, such as Hitachi This is an AI tool for elevators created by the newly manufactured workstation 2050 expert system construction tool ES/KERNER. This is composed of a CRT 3, a keyboard 4, and a processing device 5. The processing device 5 includes a part that controls the man-machine interface, a part that performs knowledge processing such as reasoning, a part that stores knowledge (data), and an elevator control device. It is made up of parts that control communications.

FIG. 2 shows the software configuration of the group management control unit W11. There is an operation control program 5FIO that directly commands and controls elevator group management control such as call assignment processing and elevator distributed standby processing.As input information for this program, the elevator positions sent from the unit control devices 20 to 22 are used as input information. .

Elevator control data table 5F including direction, car call, etc.
II. Hall call table 5F12. Elevator specification table 5F13, such as the number of elevators managed in a group, and operation control parameter table 5F14. There is a rule table 5F22. The other program is a communication program 5F20 for communicating with the AI tool, and the input/output information of this program includes a control status record table 5F21 that records elevator control status such as waiting time and rules received from the AX tool. There is a recorded rule table 5F22.

FIG. 3 is a table configuration diagram of the software used in the group management control device 1, and is an elevator control data table 5F.
II. Hall call table 5F12° Elevator specification table 5F13. Operation control parameter table 5F14
．． Control state record table 5F21. Rule table 5F
It consists of 22 blocks.

The program described below is a system program that divides a program into multiple tasks and performs efficient control, that is, an operating system (OS).
).

Therefore, the program can be started freely from the system timer or from other programs.

FIG. 4 is a schematic processing flowchart of the operation control program and the communication program.

After the power is turned on, the operation control program is reset and started and executes initial processing E10. Initial processing is a program that clears various tables, sets initial values, and initializes various input/output devices and communication devices. Next, steps E20 to E60 are repeatedly executed until the power is turned off. In step E20, landing calls for all floors are input and set in the hall call table.

In step E30, communication data from the car control device is stored in the elevator control data table SFI1. In step E40, call allocation processing is performed, in step E50, guidance notification processing is performed, and in step E
At 60, other processing such as elevator distribution processing is performed.

The communication program is started by interrupt processing from the AI tool, and the processing is so-called background processing that is performed using the idle time of processing the operation control program. First, in step E70, communication with the AI tool is established. Then, in steps E80 to E90, the control state recording table 5F21 is transmitted in response to a request from the AI tool, and control rules are received and stored in the rule table 5F22. Note that the rule table 5F22 is stored in an EEPROM that can be backed up by a battery or electrically writable and erasable so that the memory is not lost even in the event of a power outage.

FIGS. 5 and 6 are explanatory diagrams of the rule table sent from the AI tool.

FIG. 5 is a call assignment rule table, which is composed of three parts. T11 is a registered rule table indicating whether or not rules to be applied in each direction of each floor are defined, and the rules are defined where the 0 mark is added in the diagram.

This example shows that rules 1 and 3 are registered for the call to ascend to the third floor, and rule 2 is registered for the call to ascend to the fourth floor. T12 is a rule condition table that records the condition part of each rule. Conditions include general conditions such as specifying two days and times of the week, as well as load conditions, waiting time, and number of customers waiting.

There are conditions related to elevator status, such as designated elevator numbers and traffic demand. All of these conditions are handled as AND conditions, and when OR conditions are handled, they are registered as separate rules. Each piece of data is written in a judgment conditional expression. For example, the condition that the car load is 30% or less is WEIGHT = <5EKISAI x 0, 3
...(1) However, it is described as WEIGHT: load state 5EKISAI: rated carrying load.

T13 is a rule execution table that records the execution part when the conditions of each rule are satisfied, and the evaluation formula or assigned machine number is written therein. For example, if the load state is 30
The evaluation formula for selecting the elevator that can arrive the earliest from among the elevators below % is ASIGN=K FORMIN [VALUE (K)
] ・(3) However, VALUE (K): Array of evaluation values K: Variable AS corresponding to the machine number
What is actually recorded in each table, described as IGN: Assigned machine MAX: Maximum value, is the above formula changed into binary data that can be executed by a microcomputer. Note that a blank column means that there is no condition.

FIG. 6 shows a guide display rule table, which is also composed of three parts. T21 is a registered rule table indicating whether rules to be applied in each direction of each floor are defined, and has the same configuration as Tll. T22 is a condition part of each rule and has the same configuration as T12. T23
is an execution unit when the conditions of each rule are satisfied, and can select one of various display formats prepared in advance. Here too, the display form marked with an O is selected.

There is a general information display item in the display format, and there is a Q in that item.
If marked, message data is recorded in the table.

FIG. 7 is a detailed flowchart of the call allocation process explained in step E40 of FIG. Step FIO,
F20. F70. F80 indicates that all floors, ascending and descending, are being processed in order. In step F30, it is determined whether there is a hall call on the processing floor. This determination may be made to determine the presence or absence of a newly generated hall call, or simply to determine the presence or absence of a call registration, and this is determined by the call allocation method.

Here, the explanation will be continued as a determination as to whether or not a new call has occurred.

If not, the process jumps to step F70 and processes the next floor.

If there is a hall call, the process advances to step F40 and it is determined whether the allocation rule for that floor is registered. This process is a process of searching whether the Q mark is attached to the relevant floor in the registration rule table Tll explained in FIG. 5. If there is no rule marked with ○, proceed to step F65.
Step F70 executes call assignment based on predetermined known evaluation value calculations, and then proceeds to step F70. If there is a rule marked with 0, proceed to step F50 and proceed to rule condition table T.
The conditional expressions of the rule numbers to be implemented described in 12 are sequentially calculated, and it is determined whether the conditions are satisfied. If this is not true, the process proceeds to step F65, where call assignment is performed by calculating evaluation values. If it is true, call assignment is performed based on the evaluation formula described in the rule execution table T13. In addition to what is written in the form of an evaluation formula in this execution table, there is also a case where the allocation machine is directly specified, and in this case, the allocation is executed without performing evaluation calculations.

FIG. 8 is a detailed flowchart of the guidance notification process explained in step E50 of FIG. 4. Step GIO, G20
．． G70. G80 indicates that all floors, ascending and descending, are being processed in order.

In step G40, it is determined whether the guidance control rule for the floor in question is registered. This process is a process of searching whether or not there is a 0 mark at the relevant floor in the rule registration table T21 explained in FIG. If there is no rule marked with 0, the process proceeds to step G65, where predetermined guidance control is executed, and the process proceeds to step G70. If there is a rule marked with 0, proceed to step G50 and proceed to rule condition table T2.
2, the conditional expressions written in the rule numbers to be implemented are sequentially calculated, and it is determined whether the conditions are satisfied. If not established, the process advances to step G65 and predetermined guidance control is performed. If it is true, guidance control is performed in accordance with the display form described in the rule execution table T23. In this execution table, in addition to specifying the display format, there is also a case where a display message is directly specified, and in this case, the message data is directly output to the display.

FIG. 9 is a schematic processing flowchart of the AI tool 2. The AI tool is a workstation that performs normal start-up operations and then starts the elevator specification change service program. First, in step HIO, communication start processing with the elevator control device is executed. Specifically, this is a process of interrupting the elevator control device. Communication is thereby established and the elevator control status is displayed in step H20. This display edits the contents of the control state record table transmitted from the elevator control device into a table or graph and displays it on the CRT. And step H3O
-H60 is a process for inputting customer required specifications, in which the specifications are input in the form of a guidance display for input and an answer to the guidance displayed. This control method is a general expert system input method, so details will be omitted. Briefly, when customer specifications are input, the input specifications are converted into the rule table explained in FIG. 5 in step H40.

Then, the rationality of the rules is checked, and if there are any portions that cannot be converted, the process advances to step H60 and guidance is displayed again. When the changes are completed by repeating this,
Proceeding to step H70, inference is made as to how the elevator control state (for example, waiting time) will change due to the input specification change, and the results are displayed. Furthermore, advice on other possible changes to the specifications is displayed based on this result.

Then, in step H80, a determination is made as to whether or not to execute the finally input specification change, and if the specification change is to be executed, the process proceeds to step H90 and transmits the rule table to the group management control device. If the process is to be canceled, return to step H30 and start again from inputting specifications.

Similar processing is performed for changing guidance control to create the rule table described in FIG. 6.

In this embodiment, the AI tool has been explained as being operated by the customer, but it goes without saying that this can also be realized by configuring it to be connected to the elevator control device from the maintenance company through a telephone line, etc. . Furthermore, it is also possible to limit the range of specifications that a customer can change using a password or the like, so that inputs that would cause an extreme drop in performance will not be accepted. Furthermore, the contents changed by the customer can be constantly recorded so that the contents can be checked during maintenance and can be restored.

In addition, the content of the present invention can be configured without using AI tools. For example, various customer requests can be divided into a condition part and an execution part, and rules for each item can be stored in an IC card, and the customer can use the IC card. A possible configuration is such that the card is inserted only at a desired time and for a desired period.

Further, in this embodiment, an example of a processing program related to a guide alarm at a landing place has been shown, but this can also be easily applied to control of an alarm within a car. Further, the rules themselves can easily be applied to other rules other than the call assignment rules and guidance display rules shown in the embodiments, such as distributed floor rules and door control rules.

According to the present invention, part of the elevator control method can be changed on the customer side.

A part of the elevator guidance method can be changed on the customer side.
