Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management system, and more particularly to an elevator group management suitable for use in managing an elevator apparatus having an information guide notification device in each elevator hall. About the system.

[Prior Art] A group management control device in a conventional elevator group management system monitors generated hall calls online for the purpose of improving the operation efficiency of elevators and improving services for passengers. By assigning calls to the most appropriate elevators in consideration of the service situation of the above, the elevators are controlled so as to shorten the average waiting time. Also, recently, in selecting an elevator to be assigned a hall call from a plurality of elevators, a variable parameter is loaded on an evaluation function for evaluating each elevator,
Changing the variable parameter value according to traffic demand;
A method has been proposed in which a parameter value that satisfies a preset target value is stored by using the obtained result, and call assignment control is performed using the parameter according to the operating condition of the elevator. . Examples of this type of proposed system include, for example, JP-A-58-52162 and JP-A-58-6
The technology described in Japanese Patent No. 3668 is known.

In the method proposed in the above-mentioned publications and the like, two control target values of waiting time and energy saving can be set by a level command from a switch or a building management system. It evaluates calls, evaluates nearby stop calls, and introduces a stop call evaluation index that preferentially assigns generated hall calls to elevators that have many nearby stop calls. In this method, by appropriately changing the weight coefficient of the stop call evaluation index, it is possible to obtain a weight coefficient that optimizes the waiting time. Conversely, increasing this weight coefficient increases the energy saving effect. It has the advantage that it can be obtained.

Furthermore, recently, a control method for performing finer control by allowing a large number of control target values to be set has been performed.

On the other hand, as described above, in addition to performing control that satisfies a preset control target, in addition to assigning an elevator that can arrive earlier with priority to a call on a specific floor, or separately providing a button for a priority call For example, Japanese Patent Publication No. Sho 56-42550 proposes a method of designating a user (a person who generates a hall call) to assign a call to an elevator which can be serviced preferentially. In addition, there is a method in which a special button for a wheelchair or the like is used to provide a service for an elevator dedicated to a wheelchair to the call, for example.
-43303 and the like. The methods based on these proposals are extremely effective for users on priority floors and wheelchair users.

[Problems to be Solved by the Invention] The above-mentioned prior art is convenient and effective for a specific user. However, the request of the majority of general users who actually use an elevator is provided in real time. However, no consideration was given to controlling elevators based on this, and there was a problem that it was not always convenient for users.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems of the prior art, enable a user to input a desired control target from an elevator hall, select an elevator that can best achieve the input control target, and call the elevator. It is an object of the present invention to provide an elevator group management system which is assigned.

[Means for Solving the Problems] According to the present invention, the object is to allow a user to input a control target of an elevator by linking a hall call registration button installed in each elevator hall with a guidance notification device. This is achieved by allowing the control device to perform call assignment control with emphasis on the input control target value.

[Effect] The elevator group management control device determines whether or not it is possible to respond to the input even if a control target is input from the elevator hall, based on the current traffic flow, the state of each elevator, and the like. , If available
A notification device installed in each of the elevator halls is informed to the guidance notification unit to notify that the control target of the elevator can be set from the hall. The guidance notification unit determines the content to be notified by each notification device, and transmits the required notification content to the guidance notification device on the floor determined to be necessary. When the guidance information indicating that the target can be set is notified to the guidance notifying device in each floor hall, the group management control device sets the hall call button, or a state in which a signal of a special control target setting button can be accepted, and in this state, At this time, a signal from the button is received, and a setting method is changed by changing a control method of a method of selecting an elevator to which a call is to be assigned or a call assignment evaluation formula based on a control target being notified at that time. Select the elevator that best achieves the control objective and assign a call.

Hereinafter, an embodiment of an elevator group management system according to the present invention will be described in detail with reference to the drawings.

Is an input / output device, and 6C is a car call registration device.

In the elevator group management system according to one embodiment of the present invention shown in FIG. 1, the group management control device 1 includes an operation control system 1A for selecting and determining a call assignment elevator, a movement of each elevator that changes every moment, A data learning system 1B that collects various data such as the number of passengers getting on and off and the occurrence of calls and performs statistical processing, etc., and the data learning system 1B
An intelligent system 1C that creates a traffic flow pattern using the various data created in Step 1 and generates new control methods and parameters for the new pattern, and guides installed in the elevator halls on each floor according to the use status of elevators, etc. It is configured by an information guide system 1D that determines the content of notification and the notification method to be notified by the notification device. The group management control device 1 configured as described above controls the number of elevators in the car, such as information from the car call registration device 6C installed in the car, via the number control devices 2A,. Information and hall call registration button 3 installed in each hall elevator hall
, A service elevator is determined, and a guidance notification method is instructed to the guidance notification device 4H installed in each hall and the guidance notification device 4C installed in the car, and control for transmitting the notification content is performed. Further, the change of various control methods set in the group management control device 1 and the change and addition of the guidance content can be performed by using the input / output device 5 provided separately.

Since the system of the present invention having the above-described configuration can provide information guidance in real time to the guidance notification devices 4H and 4C installed in halls and cars, it is possible to provide guidance linked to the status of elevator control. Thus, the user himself / herself can input a request for selecting a service elevator, and can select an elevator that satisfies the input request.

In the group management control device 1 shown in FIG.
1A is composed of a use status judging unit 1A1, a control target judging unit 1A2, a comprehensive evaluation block 1A3, and an assignment block 1A4. The usage status determination unit 1A1 receives a signal from the hall call registration button 3 installed in each floor elevator hall,
Whether the type of the signal is a signal from a special button or a signal designating a control target is determined, and based on data collected by the learning system 1B, the current elevator Determine the usage status, etc., and from the call occurrence floor, determine whether it is a situation in which the control target may be input,
The control strategy (control method) of the elevator is determined based on these determination results. The result of this decision is that
Is transmitted to the information guide system 1D. The intelligent system 1C extracts a control method and various parameters created in advance based on the control strategy of the elevator determined by the use status determination unit 1A1, and transmits these to the control target evaluation unit 1A2. The control target evaluation unit 1A2 calculates an evaluation value for each control target item based on the transmitted control method, and transmits the calculated evaluation value to the comprehensive evaluation block 1A3. The comprehensive evaluation block 1A3, in a state in which a request for a control target from the hall can be accepted, when there is a request for this target, sets a large weighting factor for the requested control target item, and for other control target items, The weighting factor is changed according to the priority created based on the request of the manager, etc., and for each of the units, the evaluation value sent from the control item evaluation unit 1A2 is multiplied by the weighting factor, and the total sum is calculated. Comprehensive evaluation is performed by requesting, and the result is transmitted to the allocation block 1A4. Assignment block 1A4 selects the car with the smallest total evaluation value sent and assigns a call to that car.

In the above, the process of selecting and selecting a service elevator has been described focusing on the operation of the operation control system 1A.
The operation of the embodiment of the present invention including the operation of the guidance notification device 4H installed in each floor elevator hall will be described.

The hall call signal from the hall call registration button is input to the operation control system 1A at the same time as the information guidance system 1D, and further, the elevator use status determined by the operation control system 1A is Information guide system 1D with call signal
Sent to The information guide system 1D determines the guide notification method and the guide content based on these signals, and issues a command to the guide notification device 4H to notify the guide content by the determined guide notification method. In other words, if the usage status is such that the control target can be accepted at present, the information guide system 1D
When a hall call is generated, the control notification device 4H (for example, an LED display device or the like) installed in the hall informs that the control target can be input and the method thereof. For example, as shown in FIG.
In an elevator system in which three elevators are installed, consider a case where a call in the up direction occurs on the ninth floor when each car is at a position as shown in the figure and is operated in the direction indicated by the arrow. The capacity of each elevator will be 20 people. In this case, usually, the call is assigned to the second arriving car. However, since the driving situation at the time when the call is generated on the ninth floor indicates that the control target can be changed, the hall on the ninth floor is displayed as shown in FIG. First, Unit 2 is assigned a call according to a preset control target and is selected. Since there is time to arrive at the 9th floor, if there is a request to change the assignment during this time, , You can change your selection to an elevator that satisfies that goal. Therefore, the guidance notification device 4H2 of the second unit is controlled to provide a changeable guidance, and the hall lantern HL2 is controlled to display a call reception display as a service reservation display. Also,
The hall call registration buttons 3L and 3R are controlled so as to indicate that the assigned car is being provisionally registered by blinking display.
Assuming that a call is generated by the hall call registration button 3L on the car side, the guidance notification device 4H1 of the first car close to the hall call button registration button 3L is controlled to display each control target. If the user presses the hall call registration button again while the control target is displayed, the control target is transmitted to the operation control system 1A and the information guidance system 1D. Operation control system 1A
The comprehensive evaluation of the control target is performed again, the call is assigned to the newly selected car, and the real registration is performed.

If the hall call registration button 3L is not operated in the above-mentioned situation, that is, in a situation where the call assignment can be changed, the hall call on the ninth floor is temporarily set by the operation control system after a predetermined time has elapsed. It was confirmed to the registered second unit,
Registered.

In the above description, as a method for the user to input the control target in the hall, the method of pressing the hall call registration button 3 again has been described, but there are several other input methods besides the above. 5 to 7 illustrate these other input methods.

The method shown in FIG. 5 is an example in which a target selection button is provided separately from the hall call registration button 3, and the hall call registration button 3 is pressed,
After issuing a hall call, the control target can be entered,
This is a method in which a control target can be input by pressing a separately provided target selection button while the control target is displayed.

The method shown in FIG. 6 is a method in which a display and a touch panel are combined, a control target is displayed, and one of these control targets is selected and input by the touch panel. An input device combining the display and the touch panel is used. For example, it is provided beside the hall call registration button 3 and used.

The method shown in FIG. 7 is an example in which a control target is input by an ID card, a transmitter or the like possessed by a user. The control target is recorded on the ID card or the transmitter together with destination floor information. A reading device or a receiving device for these devices simultaneously reads the information and enables input of a control target. This method is effective, for example, when a guest or the like in a hotel or the like has an ID card or transmitter that also serves as a room key.

Next, the process of selecting an elevator in the operation control system 1A will be described with reference to FIG.

(1) First, determine the current use status of the elevator,
It is determined whether the traffic demand is in a congested state. The operation control system 1A determines the assigned car using a control method capable of maximizing the transport capacity if the traffic demand is congested,
If there is no congestion, it is determined that it is a time zone in which a control target can be set from each floor elevator hall (step 10).
0).

(2) Next, it is determined whether or not the type of hall call is a hall call that is input together with a control target (step 101).

(3) If it is determined in step 101 that the hall call is not input together with the control target, a control method that matches a preset control target is registered in the intelligent system 1C according to the intention of the building manager. The call assignment is evaluated from the selected decision table using the control method. For example, if the control target is a wait time, a boarding time, and a degree of congestion in a car, each evaluation function is selected from the decision table. ), Long wait evaluation,
The evaluation is performed by an evaluation method such as an average waiting time evaluation and a waiting time distribution evaluation. Therefore, the driving control system 1A selects and determines the best evaluation method from the above-mentioned evaluation methods in accordance with the current traffic demand, the evaluation method of other target items, and the priority of achieving the target. The operation control system 1A similarly selects and determines one of the methods for evaluating the longest car call, the average car call service time, the number of stops, etc. for the boarding time, and simply sets a threshold value for the congestion degree. To set an evaluation method and a target value for evaluation based on whether the threshold value is exceeded,
One of them is selected and determined from an evaluation method or the like for setting a function of the degree of increase in users until the target is reached. Normally, passengers who get on the elevator feel that the congestion degree has become severely exponential when the occupancy rate exceeds 50% of the occupancy, so this is used as an evaluation function. An evaluation method using threshold control can be used. The operation control system 1A sets the evaluation formulas used in the above-described evaluation method (waiting time: ψ _wtt , riding time: _{cit cit} , car congestion degree: ψ _cds ), and _calculates these set evaluation formulas. Each evaluation value is obtained for each unit using the obtained evaluation values, and the obtained evaluation values are added to the respective weighting factors C ₁ , C ₂ , C ₃ (C ₁ + C ₂
By multiplying by + C ₃ = 1), the sum is obtained for each car, and the elevator having the smallest sum is selected as an allocation candidate (step 102).

(4) If it is determined in step 101 that the hall call has been input together with the control target, the input control target of the weighting coefficients (C ₁ , C ₂ , C ₃ ) for the comprehensive evaluation described above is used. The elevator to which the call is to be assigned is selected by a method of performing a comprehensive evaluation by increasing the coefficient corresponding to the above, or a method in which the above-described evaluation method is changed in accordance with the control target (Step 103).

(5) With respect to the elevator selected as a candidate in step 102, the time during which the elevator can be stopped and changed is calculated, and it is determined whether or not the control target can be input in the hall. Temporarily register an allocation candidate elevator. The provisional registration of this candidate elevator is also notified to the information guide system 1D (steps 104 and 10).
Five).

(6) The elevator selected in step 103 or the elevator selected in step 102 when it is determined that the input of the control target is impossible in step 104 is officially registered as the elevator assigned to the hall call (step 106). ).

Next, the operation when the allocation candidate elevator is provisionally registered in step 105 will be described with reference to FIG.

(1) First, set the targetable time t _y from the hall, and determines the presence or absence of change in the target settings from the hall (step 201, 202).

(2) When step 202 target setting change is determined that there is no target set time t _y is determined whether was smaller summer than "0", is greater than t _y is "0", the step 202 to 204 while continuing the operation of the processing loop time t ₁ reduced from t _y, the step 202 determines whether or not there is a change in the target settings from the hall (step 202-204).

(3) In step 202, when the change of the target setting from the hall is not detected, and when it is detected in step 203 that the set time has become smaller than "0", the temporarily registered unit is fully registered. (Step 205).

(4) If a target setting request from the hall is detected in step 202, a weight coefficient for each control target item is determined in response to the request, and a total evaluation value of each unit is determined using the weight coefficient. Then, the car having the smallest total evaluation value is read and fully registered as the car to be assigned (steps 206 to 208).

(5) The machine number and the registration signal that have been registered in step 205 or 208 are sent to the information guide system 1D and the corresponding machine control device (step 209).

Next, the operation of the information guide system 1D will be described with reference to FIG.

(1) First, it is determined whether the signal transmitted from the operation control system 1A is a temporary registration signal or not (Step 301).

(2) If it is determined in step 301 that the signal is a formal registration signal,
The information indicating that the elevator is the elevator to which the call is assigned and the status of the elevator are displayed and notified to the guidance notification device in front of the main registration that is sent together with the main registration signal (step 302).

(3) If it is determined in step 301 that the signal is a temporary registration signal, the floor where the call is generated is checked, and then the guidance notification device closest to the hall call registration button that generated the call is researched and selected (steps 303 and 304).

(4) It is determined whether the guidance notification device selected in step 304 matches the provisionally registered guidance notification device of the car, and if they match, the control notification and the setting method are given to the guidance notification device. Are displayed (steps 305 and 306).

(5) If it is determined in step 305 that the information does not match, a display indicating that the information can be changed is displayed on the provisionally registered information notification device of the car, and the setting is set on the information notification device near the hall call registration button that issued the hall call. The display guides possible control targets and their setting methods (steps 307 and 308).

In the above description, it is possible to notify the general information to the guidance notification device that does not perform the driving status, control target change guidance, and the like. Also, in the above-described embodiment of the present invention, the guide notification has been described as being performed using a display device that can be viewed.
It is also possible to provide guidance notification by voice.

According to the above-described embodiment of the present invention, a user of an elevator (a user who first generates a call) can set a control target of the elevator from the elevator hall, and the user can easily use the elevator. Can be improved.

Further, according to the embodiment of the present invention, the control target set by each user and the floor and time zone of use are learned, and the control target input from the elevator hall side is used for the frequently used floor and the control target. By changing the target so as to be used as a control target for normal elevator control, it is possible to realize elevator control according to the user's intention, and the user sets the control target. The means can be eliminated, and the usability can be further improved.

Further, in the above-described embodiment of the present invention, the floors to which the control target of the elevator can be input have been described as all floors. However, the floors to which the control target can be input according to the use status of each floor. It is also possible to use only a predetermined specific floor. In this case, it is possible to take into account the specificity of the use status of each floor, and the elevator system can be operated more efficiently and more efficiently.

[Effects of the Invention] As described above, according to the present invention, when a user sets his / her favorite control target, the group management control device selects and determines an elevator that satisfies the set target in real time. In addition, since the elevator can be allocated to the floor where the call has been made, the usability of the user can be truly improved. Further, according to the present invention, when the user changes the control target, the user can use the guidance notifying device sufficiently to set the control target without constraining the user. A sense of security can also be increased.
