Description

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 suitable for providing group management control that realizes various user requests for elevator operation. The present invention relates to a management control device and its support device.

[Conventional technology]

Elevator group management control devices have undergone numerous improvements with the goal of reducing waiting time by improving operational efficiency. In particular, since the use of microcomputers in group management control devices, it has become common to use a method of predicting the waiting time for a hall call that has occurred and performing an allocation evaluation formula based on the predicted value. , Achieved the above goals to a large extent.

Further, in addition to the waiting time, a method of simultaneously considering the boarding time as in JP-A-60-148875 or the second and third goals such as energy saving in JP-A-59-82279 is proposed. Is coming.

[Problems to be Solved by the Invention]

However, recently, the buildings where elevator group management is delivered have diversified from one company-owned buildings, tenant buildings, and other office-centered buildings to hotels, government offices, and the number of multifunctional buildings called intelligent buildings has increased. ing. Also,
In an era where the individuality and sensitivity of an individual are emphasized as in recent years, in addition to shortening the waiting time, the demand from the user is "I want to get on an empty elevator.", "The time after riding is short. I want you to do it. "

By the way, among the new demands recently, "I want to get on an empty elevator" is "empty" because it is based on the requester's sensitivity, and "is always an empty elevator" and "does not touch other people". , There are various stages depending on the user, the character of the building, and the time of day, saying, "If it's not a sigh," it is not good to simply reduce the absolute value.

Moreover, even when a request that is in conflict with the waiting time is issued, the requester compares the degree of deterioration of the waiting time with the degree of achievement of other requests, and judges whether the result is good or bad.

In the conventional technology, if the goal is to improve the waiting time, naturally, the above-mentioned requirements that conflict with the waiting time cannot be met. The second requirement that considers boarding time is a method of shortening the service time of the sum by using the fact that the waiting time and boarding time have the same dimension (unit). It cannot be applied to requests such as. The second goal of energy conservation, which has a different dimension from that of waiting time, is the optimization of waiting time under the limiting condition of "20% energy saving", which balances multiple requests. It is not always what you take. As described above, the conventional technique has a problem in that it is not possible to satisfy the recent individual requirements of users.

In view of the above, an object of the present invention is to provide a group management control device and its support device that can meet various user requests for elevator group management.

[Means for Solving the Problems]

In one aspect of the present invention, target input means, means for determining a control form having a control program and / or control parameter suitable for an input control target, and group management control is executed by the determined control form. And means,
The control form determining means determines a first control form belonging to a first control form group with respect to a given control target, and a second determining device different from the first control form group. Second determining means for determining one control form belonging to the control form group of.

In a preferred embodiment of the present invention, the user inputs the target value for each control item of the elevator and the priority order or weight for them by the input means, and the target value of each control item and the priority order for them or In order to determine the weight and how the elevator behaves in order to achieve the user's request, the user's accumulated knowledge based on the traffic flow predicted by the derivation means in the support device and the user's request is used. We will derive some candidates for ordinary elevator control modes that seem to meet the requirements. Predicting each control target by simulating the movement of the elevator in the support device when controlling using each control mode under the traffic flow predicted for each of the derived control mode candidates Find the achieved value. The superiority or inferiority of each candidate is determined based on the predicted achievement value for each control target and the priority order for each control target, and the result of the candidate of the best control form and the predicted achievement value for each control target are presented. If the presented result is satisfactory, the user instructs to adopt this control mode, and if the result is not satisfied, the request is changed so that the unsatisfied goal is more emphasized. The derivation means is
A new candidate of the control form that satisfies the changed demand is derived and a predicted achievement value is obtained. At that time, a candidate whose predicted achievement value is higher than the previous demand is not satisfied is excluded from the candidates. As a result, if any candidates remain, they are presented to the user. In addition, if there is no candidate, it is judged that it is impossible to achieve the request in the normal control mode, the user is presented with the highest predicted achievement value at that time, and the control mode is adopted or the unsatisfactory target is achieved. It is required to judge whether to use a special control mode with particular emphasis on. When the user selects the control form with the highest predicted value at that time, the control form is adopted. In addition, in response to a request for selection of a special control mode, simulation is performed for the case of control using that special control mode under the predicted traffic flow, and the predicted achievement value of each control target is calculated, and the result is calculated. Present. The user can adopt the special control mode if he is satisfied with the result.

[Action]

According to the control target input by the user or the like, one control form belonging to the scheduled first control form group is determined. The group management control corresponding to this can be executed or simulated.

A control form belonging to a second (for example, special) control form group different from the first control form is determined by a request according to the result or automatically.

As a result, the control form of the group management elevator that meets various user's individual requests is derived or controlled.

Consists of. Also in this embodiment, the usual group management is performed only by the group management control device 4.

Next, the flow of processing in the personalization support device 1 will be described with reference to FIG.
This will be described with reference to FIG. In the present embodiment, a case will be described in which the office type is taken as the type of building, the number of elevators is four, the time zone is normal, and the control targets are waiting time, boarding time, and congestion degree in the car. Also, in the normal control mode in the present embodiment, another evaluation Unit is determined as the sum of the _{K h F h + K c F} c + K w F w ... (1). Here, K is a coefficient, F is an evaluation function for each goal, subscript h is waiting time, c is boarding time, w
Indicates that the item is related to the degree of congestion in the basket.

FIG. 2 is an overall flow chart in the personalization support device 1. A user inputs a request for group management control by weight or the like in step (hereinafter abbreviated as S) 101. This processing is mainly performed by the multi-target input section 1-1-1, and here, the third target input section 1-1-1 is used.
It is assumed that the weight ω is directly input to each control target as shown in the screen 2-1 of the display device 2 of the support device 1 in the figure.
In the processing of the present embodiment, the sum of the weights ω for each target item is 1.

-By the input weight ω, each control target is divided into three stages of large, medium and small within the range of ω ≧ 0.5,0.5> ω ≧ 0.2,0.2> ω.

I shall. Corresponding to the set time zone and this large / medium / small, the waiting time is as follows: -waiting time minimum control (Min control) -waiting time average control (Mean control) -longest waiting time shortest control (Min-Max Control) ・ Wait time distribution control etc. is selected. Respect boarding _{time, · K c = (0.0~0.2)} × K h · K c = (0.2~0.8) × K h · K c = (0.8~1.0) × K h or the like is selected. Concerning the degree of congestion in the car: ・ Set value = 70-80% ・ Set value = 50-70% ・ Set value = 40-50%. The control mode includes, among them, a control program such as Min-Max control and the like, and a control parameter such as 70 to 80%, and the setting time zone and the weight of the control target are large.
It is selected using the control form knowledge base 1-3 in combination with medium and small.

In this embodiment, the weight ω of each item is 0.5 for the waiting time, 0.1 for the boarding time, and 0.4 for the in-car congestion.

In S102, the control form deriving unit 1-2-1 derives the control form from the normal control knowledge 1-3-1. FIG. 4 shows an example of knowledge to which the condition (if) part applies in this embodiment. This execution part is used as a control form. In S200, the simulator 1-4 receives the derived control form, obtains the predicted achievement value for each request when the control form is used, and presents it to the user through the display device 2. An example of the presentation is shown as a screen 2-2-1 in FIG. If the user is satisfied with the presented predicted achievement value in S104, the process proceeds to S105.
In S105, in order to switch the contents of the control form database 4-4 storing the allocation control program to the determined control form, the control form is written in the IC card or the like serving as an interface, and the derivation is completed.

When the user is not satisfied with the presented predicted achievement value in S104, the input is redone from S101 so as to increase the weight of the item to be emphasized. However, in S106, if the predicted achievement value for the item changed more importantly than the previous time is not satisfied, it is determined that the normal control knowledge 1-3-1 cannot satisfy the user's request. At that time, S1
In 07, based on the special control knowledge 1-3-2, the user is presented with a special control form for improving the items that the user particularly attaches importance to, and the control form that the user judges to use may be selected. Select. An example of the special control mode is shown in FIG.
Here, is an example of setting a non-stop floor to improve the control result. Is an example in which the door time is changed to improve the control result. Furthermore, and are examples in which allocation is restricted to improve the control result. Here, assuming that the user is not satisfied with the waiting time, considering that it is normal from the knowledge ~ in Fig. 6,
Shall be selected. The control form is newly sent to the simulator 1-4, and in S200, the predicted achievement value for each request when the control form is used is obtained and presented to the user through the display device 2 together with the control form. 7th example of presentation
Shown in the figure as Drawing 2-2-2. If the user's consent is obtained in S108, in order to switch the contents of the control form database 4-4 storing the allocation control program to the determined control form in S109, the control form is changed to an IC card or the like serving as an interface. Is written and the derivation is completed.

According to the present embodiment, the control form is determined in S105 or S109, and the control form is set in the group management control device 4, so that the user's wishes are met within the range of the control form that the user is satisfied with. Group management control can be realized. In addition, since the control result when a control mode different from the current one is used for the determination is presented, the anxiety for using the new control mode is eliminated, and the control mode suitable for the actual situation can be determined.

However, if none of the special control modes presented in S107 is permitted, or if the control results in the special control modes permitted / selected in S107 are not satisfied, then the constraint conditions such as the number of elevators are fundamentally limited. In this case, in S110, using the constraint condition change request knowledge 1-3-3, it is determined whether the elevator resources are insufficient to satisfy the user's request. It is obtained by using the knowledge as shown in the figure, and in S200, it is presented like the screen 2-2-3 in FIG. 9 together with the result of the simulator 1-4. In this example, the user tried to keep the waiting time at this level and to have a degree of congestion in the car. However, in order to satisfy the demand, it is necessary to increase the number of elevators as shown in FIG. The result was obtained.

Next, the control result prediction / presentation routine S200 will be described with reference to FIG. The control form derived by the deriving means is passed to the simulator 1-4 in S201. At that time, if it is the first simulation, the conventional control form only for waiting time is also simulated. In the simulator 1-4, the number of passed control forms is set in S202 as the number of simulation cases. In S203, the passed control form is set in the control unit of the simulator, and the prediction is started. S204 is a simulation unit of passengers and elevators of Simulation, moving passengers and machines. S205 is a control simulation unit that performs allocation processing. S206
Then, collect data for each allocation. In S207, the end of the loop due to the time management of the simulation is monitored, and if it ends, the process returns to S204. When the processing ends, the data collected in S208 is statistically processed. After that, the above process is repeated for all the control forms received in S209. In S210, as a process of the control mode selection unit 1-2-2, a result (control mode) to be presented is selected from the received control modes based on the predicted achievement value obtained by the simulation. The conventional method is displayed.

The control form in which the result of the request item that the user emphasizes more than the previous time is not improved is removed.

The best total sum (weighted norm) of each control result multiplied by the weight ω is selected as the recommended result.

I shall. The result is displayed on the display device 2 in S211.
Return with S212.

When the processing of S110 and subsequent steps of the present embodiment is performed, the user is advised the number of elevators and the like in response to a request exceeding the limit of the elevator capacity of the user, so that the user can change the design and specifications from the prediction result. The effect is to be able to receive support for deciding whether to do or set the requirements for the current elevator capacity.

In addition, in the present embodiment, the individualization support device 1 is described as a device different from the group management control device 4, but the same effect can be obtained even if integrated.

〔The invention's effect〕

According to the present invention, there is an effect that it is possible to provide an elevator group management control device or its support device that can respond to various requests from users. Further, by performing the derivation of the control form and the performance evaluation of the group management control according to the control form off-line with the group management control device, it is possible to achieve both group management control that requires real-time control and simulation that cannot be executed in real time. .
