Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control device, and more particularly to an elevator group management control device with improved call allocation.

[Conventional technology]

Conventionally, the call allocation of elevators has been performed by a method of calculating an evaluation value of a generated call for each car and allocating it to one elevator having an optimum evaluation value. Recently, the traffic flow in a building is learned and simulated to determine the optimum call allocation parameter. However, an elevator controlled in this way can minimize the average waiting time of the entire building, but when picking up individual calls, it does not necessarily select an elevator that can arrive in the shortest waiting time. . For this reason, there may be a demand after the customer is delivered that an elevator that can arrive in the shortest waiting time can be assigned only to a specific floor or a specific time zone. In addition, there may be a request on a specific floor to allocate an vacant elevator for luggage transportation even if the waiting time is long.

[Problems to be solved by the invention]

As a method of coping with such a specification change after delivery, JP-A-59-31266 and JP-A-59-48364 disclose a function of reserving an event. However, with this method, it is only possible to select a coping method that suits the situation from the processing methods for the conditions assumed in advance. There are various customer requests, and in the case of unexpected requests, the maintenance company or the manufacturer responds by changing the program or the evaluation formula at present. However, changing the program or evaluation formula in order to satisfy the customer's request may make the whole inefficient, and it takes a lot of time to verify that the change is correct, and the program is completed from the customer's request. It took a long time to complete and it was not possible to respond to customers in a timely manner.

An object of the present invention is to provide an elevator group supervisory control device capable of meeting customer requests for each hall call.

[Means for solving problems]

The present invention relates to a group management of elevators provided with a plurality of elevators that serve a plurality of floors, a hall call device provided at each floor, and means for allocating generated hall calls to the elevators based on a predetermined evaluation. The control device is provided with means for assigning a specific call among the hall calls to the elevators based on an evaluation different from the predetermined evaluation.

According to an embodiment of the present invention, for call allocation, a device is provided for inputting a landing call generation condition and an allocation method at the time of the condition, the input contents are stored, and the condition input above when the landing call is generated. It can be achieved by allocating a call that coincides with the call by the input allocation method and by allocating the call according to a predetermined evaluation formula when the call does not coincide.

As a concrete means, a processing device for changing specifications, which is connected to the elevator control device or connected by a storage medium, is separately provided, and an input device for the customer to change the specifications and the input condition are input to this processing device in advance. This is achieved by preparing a means for converting the contents into a content executable by the elevator controller and a means for storing the converted contents in accordance with the defined procedure, and controlling as described below. (In general, such a processing device is called an AI tool, so it will also be referred to as an AI tool in the following description.) The specification changes input by this AI tool are divided into a condition part for control and an execution part. It is stored as a so-called rule, and its content is transmitted to the elevator control device. The condition part of this rule is classified for each event such as when a hall call occurs, when a guide is displayed, or when a specific switch is operated. When the elevator control device receives this, it judges whether or not the rule relating to the occurrence event is registered when one event occurs, and if it is registered, it determines whether or not the condition parts thereof match. If they match, the process recorded in the execution unit is performed. If they do not match, the other rules are sequentially determined, and if there is no match with any of the rules, predetermined control is performed.

[Action]

An example of the operation of the elevator control device configured as above will be described. It is assumed that a customer requests from 10 to 11 o'clock that an empty car should be assigned to an upward call on the fifth floor. At this time, when the customer inputs according to the guidance of the AI tool, the result is registered in the event when the hall call occurs, and the condition part is the first judgment part called the 5th floor upward call and 10 o'clock to 11 o'clock It is decomposed into the second judgment part, and the control rule called AND condition of these two judgment parts is added. Then, the execution unit is registered with the content that the assigned elevator is selected from the elevators whose load in the car is 30% or less. This AI tool refers to what percentage of the load in the car refers to the vacant car or whether it is controlled so that the vacant car can be created when there is no vacant car, or it calls the most vacant car at that time In order to interpret the information such as “No” and the like into what the elevator control device can execute, the necessary questions are displayed on the display and the response is sought, and the conditions are organized by repeating the questions. Furthermore, the AI tool points out that it is unreasonable with the already registered condition, and it is possible to infer that the trouble that occurs when the customer's request is taken as it is, for example, the average waiting time becomes 50% or more worse. Show it.

The rule registered in this way is transmitted to the elevator control device. Then, the elevator controller determines whether or not it coincides with the registered event each time a hall call occurs, and if it is an upcall on the 5th floor that occurs between 10 o'clock and 11 o'clock, Select the optimum elevator from the list. If the condition is not met, for example, if the call is on the 6th floor, the call is assigned according to the evaluation formula.
By controlling in this way, required functions can be easily realized without changing the entire system.

〔Example〕

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

FIG. 1 is an overall configuration diagram of the hardware of the present invention. The elevator control device 1 is composed of a group management control device 10 and respective unit control devices 20 to 22, and the construction method is a well-known microcomputer control method. Input to the group management control device is the signal from the hall call registration device 11 on each floor and the building management device.
There is a signal from 12, and the output is a signal from the voice guidance device 13 at the hall or the display device 14 at the hall. The unit control device controls the running of the elevator cars 30 to 32 and controls the doors, and the alarm 15 in the car such as the car day spray and the voice guidance device in the car, the hall lantern, the chime, etc. Control the landing alarm 16. The AI tool 2 is connected to the group management control device using the communication line 6. This connection method is not limited to the method of connecting via a communication line, and another method such as a method of connecting via a storage medium may be used. This AI tool is a commercially available workstation, for example, ES / KERNER, an expert system construction tool for the workstation 2050 manufactured by Hitachi, Ltd.
It is an AI tool for elevators created by. This is composed of CRT3, keyboard 4 and processing unit 5, and processing unit 5 controls man-machine interface, knowledge processing such as inference, and knowledge (data).
Is stored and a part that controls communication with the elevator control device is made.

FIG. 2 shows the software configuration of the group management control device 1. There is an operation control program SF10 that directly commands and controls elevator group management control such as call allocation processing and elevator distributed standby processing, and as the input information of this program, the position of the elevator sent from the machine control devices 20-22. , An elevator control data table SF11 such as directions and car calls, a hall call table SF12, an elevator specification table SF13 such as the group management number of elevators, an operation control parameter table SF14, and a rule table SF22. The other program is the communication program SF20 for communicating with the AI tool.The input / output information of this program is the control status record table SF21 which records the control status of the elevator such as waiting time and the rules received from the AI tool. There is a recorded rule table SF22.

FIG. 3 is a table configuration diagram of software used in the group supervisory control device 1, which is an elevator control data table SF.
11, Hall call table SF12, Elevator specification table SF
13, each block of the operation control parameter table SF14, the control state recording table SF21, and the rule table SF22.

The program described below is a system program that divides the program into a plurality of tasks and performs efficient control, that is, an operating system (O
S).

Therefore, it is possible to freely start the program from the system timer or from another program.

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

After the power is turned on, the operation control program starts a reset and executes the initial processing E10. The initial process is a program for clearing various tables, setting initial values, and initializing various input / output devices and communication devices. Next, steps E20 to E60 are repeatedly executed until the power is turned off. At Step E20, the hall calls for all floors are input and set in the hall call table. At step E30, the communication data from the machine controller is stored in the elevator control data table SF11. At step E40, call assignment processing is performed, and at step E50, guidance notification processing is performed. Then, in step E60, other processing such as distributed processing of the elevator is performed.

The communication program is activated by an interrupt process from the AI tool, and the process is a so-called background process, which is performed by using the idle time of the process of the operation control program. First, establish communication with the AI tool at step E70. Then, in steps E80 to E90, the control state recording table SF21 is transmitted in response to the request of the AI tool, and the control rule is stored in the received rule table SF22. In addition, the rule table SF22 can be backed up by electric power or electrically written and erased so that the memory is not lost even in the event of a power failure.
Stored in EEPROM.

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

FIG. 5 is a call assignment rule table, which is composed of three parts. T11 is a registration rule table showing whether or not a rule to be applied is defined for each direction of each floor, and the rule is defined where a circle is attached in the drawing. This example shows that rules 1 and 3 are registered for an ascending call on the third floor, and rule 2 is registered for an ascending call on the fourth floor. T12 is a rule condition table recording the condition part of each rule. The conditions include general conditions such as the day of the week and the time of day, and load conditions, waiting time, the number of waiting passengers, designated number of units, and the condition of the elevator such as traffic demand. All of these conditions are handled as AND conditions, and when handling OR conditions, they are registered as separate rules. Each of these data is written by a judgment conditional expression. For example, the condition that the load of the car is 30% or less is WEIGHT = <SEKISAI × 0.3 (1) However, WEIGHT: load state SEKISAI: rated load capacity is described.

T13 is a rule execution table recording the execution unit when the condition of each rule is satisfied, and the evaluation formula or the assigned machine number is written. For example, load condition is 30%
The evaluation formula that selects the elevator that can arrive earliest from the following elevators is ASIGN = K FOR MIN [VALUE (K)] (3) However, VALUE (K): Array of evaluation values K: Variable corresponding to the machine ASIGN: Assigned machine MAX: Maximum value. What is actually recorded in each table is that each of the above expressions is changed into binary data that can be executed by the microcomputer. A blank means that there is no condition.

FIG. 6 shows a guide display rule table, which is also composed of three parts. T21 is a registration rule table showing whether or not a rule to be applied for each direction of each floor is defined, and has the same structure as T11. T22 is the condition part of each rule and has the same structure as T12. T23 is an execution unit when the condition of each rule is satisfied, and one of various display forms prepared in advance can be selected. In this case as well, the display form marked with a circle is selected. In the display form, there is an item for general information display, and when the item is marked with a circle, message data is recorded in the table.

FIG. 7 is a detailed flow chart of the call assignment process described in step E40 of FIG. Steps F10, F20,
This shows that F70 and F80 are sequentially processing the floors that are rising and falling. At Step F30, it is determined whether there is a hall call on the treatment floor. In this determination, the presence or absence of a newly generated hall call may be determined, or the presence or absence of a call registration may be simply determined, which is determined by a call allocation method. Here, the description will be continued assuming that a new call has occurred. Otherwise Step F70
Jump to and process the next floor. If there is a hall call, go to step F40 and determine whether the allocation rule for that floor is registered. This process is a process of searching whether or not the mark of the floor is marked in the registration rule table T11 described in FIG. If there is no rule marked with a circle, the process proceeds to step F65 to execute call assignment by a predetermined publicly known evaluation value calculation, and then proceeds to step F70. If there is a rule marked with a circle, the process proceeds to step F50 to sequentially calculate the conditional expressions of the rule numbers to be executed described in the rule condition table T12, and determine whether or not the condition is satisfied. If not, step F65
Proceed to and assign the call by calculating the evaluation value. If it is established, the call is assigned by the evaluation expression described in the rule execution table T13. In this execution table, in addition to those described in the form of the evaluation formula, the assigned machine may be directly specified. At this time, the assignment is executed without performing the evaluation calculation.

FIG. 8 is a detailed flow chart of the guide notification process described in step E50 of FIG. Step G10, G20, G70, G8
A value of 0 indicates that the process of all floors going up and down is being performed in order. At Step G40, it is determined whether or not the guidance control rule for the floor is registered. This process is the sixth
At the floor of the rule registration table T21 explained in the figure ○
This is a process of searching for whether or not there is a mark. If there is no rule marked with a circle, go to step G65 to execute a predetermined guidance control and go to step G70. If there is a rule marked with a circle, proceed to step G50 and rule condition table T22
The conditional expressions described in the rule numbers to be executed are sequentially calculated, and it is determined whether the conditions are satisfied. If not established, the process proceeds to step G65 to perform predetermined guidance control. If it is established, guidance control is performed according to the display form described in the rule execution table T23. In this execution table, in addition to the method of designating the display form, the display message may be directly designated. In this case, the message data is directly output to the display.

FIG. 9 is a schematic processing flow chart of the AI tool 2. The AI tool is a workstation, and after performing a normal startup operation, it starts the elevator specification change service program. First, at step H10, a process for starting communication with the elevator control device is executed. Specifically, it is a process of interrupting the elevator control device. This establishes communication and displays the elevator control status at step H20. This display edits the contents of the control state recording table transmitted from the elevator controller into a table or a graph and displays it on the CRT. Then, in steps H30 to H60, the specifications are input in the form of inputting the customer-required specifications and instructing the guidance display for input and the answer thereto. Since this control method is an input method of a general expert system, its details are omitted. In outline, when customer specifications are input, the specifications input in step H40 are converted into the rule table described in FIG. Then, the rationality check of the rules is performed, and if there is a portion that cannot be converted, the process proceeds to step H60 and the guidance is displayed again. When the change is completed by this repetition, the process proceeds to step H70, infers how the control state (for example, waiting time) of the elevator is changed by the input specification change, and the result is displayed. In addition, another possible specification change advice for this result is displayed. Then, in step H80, it is determined whether or not the finally input specification change is to be executed, and if it is to be executed, the process proceeds to step H90 to send the rule table to the group management control device. If you want to cancel, return to step H30 and try again from the specification input.

The same process is performed for changing the guidance control.
Create the rule table described in the figure.

In the present embodiment, the AI tool is described as operated by the customer, but it goes without saying that this can also be realized by configuring the maintenance company to be connected to the elevator control device through a telephone line or the like. . Furthermore, it is possible to limit the range of specifications that can be changed by the customer by using a password or the like so that the input cannot be accepted when an input that causes an extreme deterioration in performance is received. Further, the contents changed by the customer can always be recorded so that the contents can be confirmed and restored during maintenance.

Also, the content of the present invention can be configured without using an AI tool. For example, it is conceivable that various requirements of the customer are stored in the IC card according to the rule of each item divided into the condition section and the execution section, and the customer inserts the IC card at a desired time and a desired period.

Further, in the present embodiment, an example of the processing program of the portion related to the guidance alarm of the landing is shown, but it is easy to apply this to the control of the alarm in the car. further,
It is easy to apply the rule itself to another rule other than the call assignment rule and the guide display rule shown in the embodiments, for example, the distributed floor rule and the door control rule.

〔The invention's effect〕

According to the present invention, it is possible to provide an elevator group management control device capable of responding to a customer request for each hall call.
