Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an elevator group management control device, and more particularly to an improvement in a guidance control device. 2. Description of the Related Art Conventionally, after an elevator has been delivered to a customer, there has been a request that an elevator which can arrive at a specific floor or a specific time zone with the shortest waiting time may be requested. Further, on a specific floor, there may be a request that an empty elevator should be allocated even if the waiting time is long for carrying cargo. As a method for coping with such a specification change after delivery, JP-A-59-31266 and JP-A-59-48364 disclose a function for reserving an event. [0004] However, in this method, it was only possible to select a coping method suited to the situation from a processing method for a condition assumed in advance. [0005] In addition, there is a case where a request is made that a special guidance is required only for a specific floor or a specific time zone.
In particular, recently, guidance display using characters or figures using a display has been adopted, and a number of specification changes have occurred after delivery. For example, if you book a call and use the guidance display method when the call is likely to wait a long time, "Please wait for a while." Or use the waiting time to display a product commercial Is required. [0006] An object of the present invention is to provide an elevator operating condition.
Is a benzalkonium provide a group control device for an elevator which can perform a guidance display suitable. SUMMARY OF THE INVENTION The present invention provides one aspect thereof.
The hall call devices provided on each floor and
Multiple elevators to service multiple floors in response to calls
Data and their service status according to the scheduled rules.
Group control of elevators equipped with a guide device for guiding to the parking lot
Means for storing a plurality of guidance rules in the apparatus;
Means for storing execution conditions for each of the guidance rules, and waiting
Including time display, elevator position display or planned stop floor display
Out of multiple display items, one for each of the above guidance rules
Means for storing a plurality of guidance display items, and the execution condition
When the above is satisfied, the above guide table corresponding to the applicable guide rule
Means for displaying guidance along the indicated items.
And Therefore, when a predetermined execution condition is satisfied,
The operation status at that time is different from the previous information display
A guidance display excellent in a user service corresponding to the information is realized. In one embodiment of the present invention ,
One of a plurality of guidance display rules is applied,
Display items (forms) are prepared and multiple guidance tables for display
One or more of the above
Guidance display items (forms) are set, and these
The display is executed when a predetermined condition is satisfied. Further
In, and the predetermined conditions, the guide display rules (hardness at the time of its conditions
Is provided, and the input contents are stored.
When a condition that matches the input condition occurs, guidance is provided according to the input guidance display rule , and when the condition does not match, a predetermined normal guidance display is performed. As a specific means, there is provided a separate processing device for specification change, which is connected to the elevator control device or connected by a storage medium, and this processing device is inputted with an input device for the customer to change the specification. This is achieved by preparing means for converting the contents into executable contents by the elevator control device and means for storing the converted contents in accordance with a procedure in which conditions are predetermined, and performing control as described below. (Since such a processing device is generally called an AI tool, it is also referred to as an AI tool in the following description.) The specification change content input by the AI tool is divided into a condition part for performing control and an execution part. Then, the rules are stored as so-called rules, and the contents are 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 guidance display is performed, or when a specific switch is operated. Upon receipt of this, the elevator control device determines whether a rule relating to the event has been registered when one event has occurred, and if registered, determines whether or not the condition part matches. If they match, the process recorded in the execution unit is performed.
If they do not match, the other rules are sequentially determined. If none of the rules match, predetermined control is performed. An example of the operation of the thus configured elevator control device will be described. It is assumed that a customer requests that an empty car be assigned to an upward call on the fifth floor between 10:00 and 11:00. At this time, the customer follows the guidance to the AI tool and makes an input, and the result is registered in the event at the time of the hall call occurrence, and the condition part is the first judgment part of the fifth floor upward call and from 10:00 to 11:00. It is decomposed into a second judgment part, and AND of these two judgment parts
A control rule called a condition is added. Then, the content that the execution unit selects the assigned elevator from the elevators in which the load in the car is 30% or less is registered. This AI tool indicates whether the empty car indicates what percentage of the load in the car or less. If there is no empty car, the AI tool controls the empty car so that it can be opened or calls the most empty car at that time. In order to interpret the contents as executable by the elevator control device, a necessary question is displayed on a display, a response is requested, and conditions are arranged by repeating the process. In addition, the AI tool points out that it is unreasonable with the already registered conditions, and it is also inferred that defects that occur when the customer's requirements are directly adopted, for example, that the average waiting time is worse by 50% or more. If it is displayed. The registered rules are transmitted to the elevator control device. The elevator control device determines whether or not the registered event coincides with the registered event each time a hall call occurs. If the fifth floor is an ascending call between 10 and 11 o'clock, the load in the car is 30% or less. Select the optimal elevator from among them. If the condition does not apply, for example, if the call is on the sixth floor, the call is assigned according to the evaluation formula. By performing such control, required functions can be easily realized without changing the entire system. FIG. 1 to FIG. 9 show an embodiment of the present invention.
I will explain using. FIG. 1 is an overall configuration diagram of the hardware of the present invention. The elevator control device 1 is a group management control device 10
And each of the unit control devices 20 to 22. The configuration method is a known microcomputer control method. The input of the group management control device includes a signal from the hall call registration device 11 on each floor and a signal from the building management device 12, and the output includes a signal from the hall voice guidance device 13 and the hall display device 14, and the like. The unit control device is the elevator car 30 to 32
Of the car and control of doors, and control of an in-car annunciator 15 such as an in-car display and an in-car voice guidance device, and a landing annunciator 16 for each car such as a hall lantern and a chime. The AI tool 2 is connected to the group management control device by using a communication line 6. This connection method is not limited to the connection method using a communication line, but may be another method such as a connection method via a storage medium. The AI tool is a commercially available workstation, for example,
This is an elevator AI tool created by the expert system construction tool ES / KERNER of the workstation 2050 manufactured by Hitachi, Ltd. It is composed of a CRT 3, a keyboard 4 and a processing device 5.
Consists of a part that controls a man-machine interface, a part that performs knowledge processing such as inference, a part that stores knowledge (data), and a part that controls communication with an elevator control device. FIG. 2 shows a software configuration of the group management control device 1. There is an operation control program SF10 for directly instructing and controlling elevator group management control such as call allocation processing and elevator distributed standby processing, and the position of the elevator transmitted from the machine control devices 20 to 22 as input information of this program. , Direction, car call, etc. elevator control data table SF11, hall call table SF
12, an elevator specification table SF13 such as the number of elevators managed in a group, and an operation control parameter table S
F14 and a rule table SF22. Another program is a communication program SF20 for communicating with the AI tool. The input / output information of this program includes a control state recording table SF21 that records the control state of the elevator such as waiting time and a rule 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 management control device 10, which is an elevator control data table SF11, a hall call table SF12, an elevator specification table SF13, an operation control parameter table SF14, a control state recording table SF21, and a rule. It is composed of each block of the table SF22. It is assumed that the program described below is managed under a system program that divides the program into a plurality of tasks and performs efficient control, that is, an operating system (OS). Therefore, the program can be started from the system timer or from another program freely. 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 starts a reset and executes an initial process E10. The initial processing is a program for clearing various tables, setting initial values, and performing initial processing for various input / output devices and communication devices. Next, steps E20 to E60
Is repeatedly executed until the power is turned off. In step E20, hall calls for all floors are input and set on the hall call table. In step E30, communication data from the car controller is stored in the elevator control data table SF11. In step E40, a call assignment process is performed, and in step E50, a guidance notification process is performed. Then, in step E60, other processing such as elevator distributed processing is performed. The communication program is started by an interrupt process from the AI tool, and the process is a so-called background process which is performed using the idle time of the process of the operation control program. First, in step E70, communication with the AI tool is established. Then, steps E80 to E90
In response to the request from the AI tool, the control state recording table SF21 is transmitted, the control rule is received, and the control rule is stored in the rule table SF22. The rule table SF22 is backed up by a battery or stored in an electrically erasable EEPROM so that the memory is not lost even during a power failure. FIGS. 5 and 6 are explanatory diagrams of the rule table transmitted from the AI tool. FIG. 5 shows a call assignment rule table, which is composed of three parts. T11 is a registration rule table indicating whether a rule to be applied is defined for each floor direction, and the rule is defined where a circle is provided 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 that records the condition part of each rule. The conditions include general conditions such as designation of the day of the week and time, as well as conditions relating to the state of the elevator such as load conditions, waiting time, the number of waiting passengers, designated cars, and traffic demand. All of these conditions are A
It is handled as an ND condition, and is registered as another rule when handling an OR condition. Each of these data is described by a judgment condition expression. For example, the condition that the load of the car is 30% or less is as follows: WEIGHT = <SEKISAI × 0.3 (Equation 1) where WEIGHT: load state SEKISAI: rated load capacity is described. T13 is a rule execution table that records execution units when the conditions of each rule are satisfied.
Or, the assigned car number is written. For example, an evaluation formula for selecting an elevator that can arrive at the earliest among elevators with a load state of 30% or less is as follows: ASIGN = K FOR MIN [VALUE (K)] (Expression 3) where VALUE (K): array of evaluation values K: variable ASIGN corresponding to the number: ASIGN: assigned number MAX: maximum value What is actually recorded in each table as described above is obtained by changing each of the above expressions into binary data executable by the microcomputer. A blank means that there is no condition. FIG. 6 shows a guidance display rule table, which also comprises three parts. T21 is a registration rule table indicating whether rules to be applied for each floor direction are defined, and has the same configuration as T11.
T22 is a condition part of each rule and has the same configuration as T12. T23 is an execution unit when the condition of each rule is satisfied, and various guidance display items (form) prepared in advance
You can choose one. Again, I put a circle
The guidance display item (form) is selected. Guidance display items (shape
In (state) , there is an item of general information display, and when the item is marked with a circle, message data is recorded in the table. In the illustrated example, the registration rule text shown in FIG.
As shown in the table, rule 1 is for 1U ascending call
The rule is applied as shown in the condition table of FIG.
1 is executed between 8:00 and 9:00, and
(C) The guidance display item (form) is shown in the execution unit table.
The "arrival order display" is performed as described above. That is, the work hours
From 8:00 to 9:00 which is the obi, the first floor which is the lobby floor rises
Order of arrival of each elevator arriving one after another for a call
Is displayed as a guide. Similarly, above the middle floor of 2-5
Wait for ascending calls 2U-5U and descending calls 2D-5D
When the time (WAITT) is longer than the predetermined value (60 seconds)
"General information is being held in the lobby."
Display 3 ”and Rule 3 for distracting waiters is applied.
It is. Furthermore, for the descending call 6D of the top floor 6th floor,
Traffic demand (TRAFIC) is higher than a predetermined value (1000)
`` Ele position display '' and `` Scheduled stop floor display ''
Rule 2 is applied. As shown in FIG.
One of multiple guidance display rules 1 to 3 is applied for each call
And a plurality of guidance display items (forms) shown in FIG.
And that of multiple display methods (rules 1-3) for display
In each case, one or more of the guidance display items (forms)
The guidance display is set as shown in FIG.
Is executed when the condition of FIG. FIG. 7 is a detailed flowchart of the call assignment process described in step E40 of FIG. Steps F10, F20, F70, and F80 indicate that the processes of all floors that are ascending and descending are sequentially performed. Step F3
At 0, it is determined whether there is a hall call on the processing 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 is continued as the determination of the occurrence of a new call. If not, the process jumps to step F70 to perform the processing of the next floor. If there is a hall call, the process proceeds to step F40, and it is determined whether the allocation rule for that floor is registered.
This process is a process for searching whether or not a circle is attached to the floor of the registration rule table T11 described in FIG. If there are no rules marked with ○, step F6
The process proceeds to step F5, where a call is assigned by a known evaluation value calculation, and the process proceeds to step F70. If there are any rules marked with ○, 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 the conditions are satisfied. If not, the process proceeds to step F65 to perform call assignment by evaluation value calculation. If the condition is satisfied, the call is assigned by the evaluation expression described in the rule execution table T13. In addition to the one described in the form of the evaluation expression in this execution table, there is also a case where the assigned machine is directly designated. In this case, the assignment is executed without performing the evaluation operation. FIG. 8 is a detailed flowchart of the guidance notification process described in step E50 of FIG. Step G1
At 0, G20, G70, and G80, it is shown that the processing of all floors up and down is sequentially performed. In step G40, it is determined whether or not the guidance control rule for the floor is registered. This process is a process for searching whether or not the circle at the corresponding floor in the rule registration table T21 described with reference to FIG. If there are no rules marked with 印, the flow proceeds to step G65, executes predetermined guidance control, and proceeds to step G70. Step G if there is a rule with a mark
The process proceeds to step 50, where the conditional expressions described in the rule number to be executed in the rule condition table T22 are sequentially calculated to determine whether or not the condition is satisfied. If not, the process proceeds to step G65, where predetermined guidance control is performed. If the rule is satisfied, guidance control is performed in the display mode described in the rule execution table T23. In this execution table, a display message may be directly specified in addition to the method of specifying the display mode. 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, and after performing a normal start-up operation, starts an elevator specification change service program. First, in step H10, communication start processing with the elevator control device is performed. Specifically, this is a process of interrupting the elevator control device. As a result, when the communication is established, the elevator control status is displayed in step H20. In this display, the contents of the control state recording table transmitted from the elevator control device are edited into a table or a graph and displayed on a CRT. Steps H30 to H60 are input processing of the specification required by the customer, and the specification is input in the form of indicating the guidance for input and indicating the answer thereto. Since this control method is an input method of a general expert system, its details are omitted. In brief, when the customer specification is input, the specification input in step H40 is converted into the rule table described in FIG. Then, the rationality of the rules is checked, and if there is a part 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 to infer how the control state (for example, the waiting time) of the elevator changes due to the input specification change, and displays the result. Further, another specification change advice that can be taken with respect to this result is displayed. Then, in step H80, it is determined whether or not to execute the finally input specification change.
Proceed to 90 and transmit the rule table to the group management controller. If the operation is to be stopped, the process returns to step H30 and starts again from the specification input. The same processing is performed for the change of the guidance control to create the rule table described with reference to FIG. In the present embodiment, the AI tool has been described as being operated by the customer, but this can be realized even if the maintenance company is connected to the elevator control device through a telephone line or the like. Needless to say. Furthermore, the range of specifications that can be changed by the customer can be limited by using a password or the like, so that when an input that causes extreme performance degradation is input, it is not accepted. Further, the contents changed by the customer can be always recorded so that the contents can be confirmed at the time of maintenance and can be restored. Further, the contents of the present invention can be constituted without using an AI tool. For example, it is conceivable that various requirements of a customer are divided into a condition part and an execution part, and each rule is stored in an IC card. The customer inserts the IC card at a desired time and at a desired time. Further, in this embodiment, an example of the processing program of the part related to the guide information of the landing is shown, but it is easy to apply this to the control of the information in the car. Further, it is easy to apply the rules themselves to rules other than the call assignment rules and the guidance display rules described in the embodiment, for example, the rules of distributed floors and the control rules of doors. According to the present invention, the operation status of the elevator
Information display at the platform according to the user service
It can be carried out.
