Abstract

PURPOSE:To keep off the extreme worsening of efficiency due to overregulation for a degree of congestion in a cage by assigning a service elevator on the basis of an allowable value to the degree of congestion in the cage in adding an allowable value of latency to the former. CONSTITUTION:A user sets an allowable value of a degree of a congestion in a cage and that of latency to a group-control governing system 2 with an input unit 1. If it is difficult for this setting, a degree of significance to the degree of congestion in the cage is inputted through an intelligence part 2-1, and a fuzzy inference taking account of traffic situations is applied to the allowable value of congestion in the cage and the allowable value of the latency, converting them and these values are set. Then, an assigning part 2-2 performs its assignment according to the precedence of three stages, namely, the elevator coming in earliest in two allowable values, the second one of the lowest congestion in the cage satisfying the latency allowable value and the third one coming in earliest. Thus, the extreme worsening of efficiency due to overregulation for the degree of congestion in the case can be prevented from occurring.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to group control elevators, and in particular to elevators.
This invention relates to an elevator in which the degree of congestion in the car can be selected.

[Conventional technology]

When assigning a generated hall call to a serviceable elevator, the hall waiting time is mainly used as an index. In addition to that, there is a method that takes into consideration the degree of congestion in the car.
There is No. 2-47787, and Japanese Patent Application Laid-open No. 52-13829.
No. 1 describes the exclusion from the allocation of elevators that are expected to be full, and furthermore, Special Publication No. 62-3075 describes the exclusion of elevators that are expected to be full. Changes in allocation parameters using +1 are disclosed.

Further, as an application of fuzzy theory to elevator control, Japanese Patent Application Laid-Open No. 1983-1999. -1.97378 and JP-A-62-46880.

[Problem to be solved by the invention]

In the prior art described above, the degree of congestion within the car is not taken into consideration at the time of allocation, except when the occurrence of a 2nd car is expected.

Recently, however, I have been avoiding riding face-to-face with other people, even if the elevator is not full.C: ``I want to ride an empty elevator.

There are many buildings (hotels, etc.) that have strong demands such as "," and responding to these demands has been an issue.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator group management control system that can proactively respond to requests regarding the degree of congestion within a car, in view of the circumstances described in -1- above.

[Means to solve the problem]

The purpose of item 2 is to provide a means to accept requests regarding the degree of congestion within the car, and based on those requests, to determine the permissible value of the degree of congestion within the car and satisfy it while taking into consideration the building use and traffic conditions. This is achieved by setting a tolerance value for the waiting time that varies (generally increases) in order to increase the waiting time, and allocating service elevators within the range of these two tolerance values.

[Effect]

A user lines up at the group management control device and sets a tolerance value for the degree of congestion within the car and a tolerance value for waiting time. if,
If the setting is difficult, the importance level for the in-cage congestion degree is inputted through a means for supporting the setting in the group management control device N, and the values are converted into a permissible value for the in-cage congestion degree and a permissible value for the waiting time.

In the group management control device, based on the two set tolerance values, ■: Car number 1 that comes the earliest among the two tolerance values ■: Car number 1 with the lowest congestion level in the car that satisfies the waiting time tolerance value: Allocation is performed according to three priority levels, starting with the earliest arriving machine.

Further, the setting support means converts the ambiguous value of the degree of importance to the degree of congestion in the car into two allowable values by using fuzzy inference taking into account traffic conditions and the like.

By the above method, it is possible to realize a group management control device that actively adjusts the degree of congestion within the car.

〔Example〕

A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is an overall configuration diagram in the case where the permissible value of the degree of congestion in the car is directly input according to the second embodiment.

The group management control device 2 includes an intelligent unit 2-1 that determines the traffic mode based on operation information such as hall calls, car calls, car loads, etc., and an allocation unit that allocates calls using parameters that determine the determined traffic mode. There is part 2-2. 2-1
and 2-2 are realized as software on a microcomputer. An input device 1 for inputting a permissible value of the degree of congestion in the car is installed offline with the input device 2, and is connected to the allocation unit 2-2 through a transmission line. Further, the hall call buttons 3 on each floor and the car control device 4 for each car 5 are also connected to the group management control device 2.

From the input device 1, an input person such as a building manager inputs the allowable value (in-car congestion allowable value) CP for the congestion degree of the service corner assigned to the hall call, and protects (satisfies) the CP. Input the permissible value (wait time permissible value) WP of the waiting time that becomes longer due to this. The two input allowable values CP and WI) are sent to the allocation section and stored in the memory.The processing in the allocation section will be explained with reference to FIG. First, initial settings are performed in step 101.

Received in-car congestion tolerance value cp and waiting time tolerance value W
P and work variables are set. The contents of the work variables used here are as follows.

WM: Minimum waiting time of the car that satisfies two tolerance values WMC: WM car number CM = Elevator that does not satisfy the car congestion tolerance but satisfies the waiting time tolerance - The lowest car number among the cars The value of the congestion degree in the car of the car with the lowest congestion degree CMC: The car number of CM WX: The value of the waiting time of the car with the shortest waiting time among the cars that do not satisfy the waiting time tolerance wxc: The car number of wx Steps 102, 116, and 117 are loops for all machines. In step 103, the predicted waiting time for the hall call is calculated and set as WT.

In step 104, the pre-41 car congestion degree for the hall call is calculated and set as CR. The calculation performed here uses a method known in Japanese Patent Publication No. 3075/1983, which utilizes parameters based on traffic flow modes and learning results. After determining the WT and CR that serve as the basis for allocation, step 10
Based on the five comparisons between 5 and 115, (1): If both the car congestion tolerance and waiting time tolerance are satisfied, the elevator number of the elevator that comes earliest among them is substituted into WMC.

-Secondly, if the car congestion tolerance is not satisfied, the car number of the elevator that is the least crowded within the waiting time tolerance is substituted into the CMC.

(2): If there is no elevator that satisfies the waiting time tolerance value, the car number of the elevator that comes earliest among them is substituted into WXC.

Do this work.

After completing calculation and substitution for all machines, step 11
8 to 122, the service elevator is allocated.

First, in step 118, it is determined whether there is a first machine that satisfies the condition (■), and if there is a corresponding machine,
In step 119, it is assigned to the vMC number. If there is no corresponding machine, the condition of ■ is determined in step 120,
If the condition is satisfied, a CMC machine is assigned in step 121, and if not, a WXC machine is assigned in a step 122.

According to the present invention, it is possible to provide a unique group management control device that actively reflects the demands of building managers and the like regarding the degree of congestion within the car. In addition, here, we used predicted waiting time for allocation evaluation, but instead, we may use an evaluation formula that adds parameters such as the maximum predicted waiting time including other hall calls, or taking into account energy saving, etc. It is clear that the method of the present invention can also be used when using assignment evaluation methods such as .

By the way, if the permissible in-cage congestion degree value and the waiting time value are set without considering the elevator installation environment and traffic conditions, the performance may not be achieved at all. Although the above invention is convenient for newcomers with in-depth knowledge of elevator operation, it cannot be used immediately by general building managers. Therefore, in the first embodiment described above, a means for supporting the setting of the permissible value for the degree of congestion in the car is added.
A second embodiment of the present invention will be described below with reference to FIGS. 3 to 8.

FIG. 3 is an overall configuration diagram of the second embodiment.

A new tolerance setting support section 2-3 is provided which can receive input signals from the input device 1.

Next, the processing in the allowable value setting support section 2-3 will be explained using FIG. Here, the allowable value setting support section 2-3 is composed of a one-chip microcomputer having a CPU, memory, etc.

Administrators, etc. who are qualified to input the importance level should use input device 1.
1. How important is the level of congestion in the car? OO drip infusion and manual labor for 1 tsubo. The input results and other elevator conditions used in the following rules are read in step 201. Here, it is assumed that 60 points are input as the degree of importance. In addition, the elevator situation received from the intelligence department will be explained based on the conditions that the building is used for a hotel, the traffic flow mode is normal mode, the specific user rate in the building is 40%, and the minimum temperature is 8 degrees Celsius.

In step 202, knowledge processing is performed based on the rules.

In this embodiment, the following four rules are used.

Rule 1: If r the lowest temperature but [5 degrees or more and 15 degrees or less” Not then Assign J to the vacant elevator teeth [Especially empty elevators] "assign to" shall be.

Rule 2: If r building use” "Hotel" then r membership function” teeth "Use the one for hotels" shall be.

Rule 3: If r building use” but "- company building" then r membership function” teeth "Use the one for company-specific buildings." shall be.

Rule 4: If r building use” but "Tenant Building" then r membership function” teeth “(Hotel) *, 5+(- company only) Bill) *, 5 is used.” shall be.

In the rules, "not" means negation.

Furthermore, "especially ~" is used by squaring the original membership function, and "a little ~" is used by taking the square root of the original membership function.

Rule 2 is executed here by comparing the conditions shown earlier with the rule.

In step 203, fuzzy inference is performed.

The fuzzy rules are as follows.

Fuzzy rule: If r input importance is "expensive" N.D. “Specified customer J but "few" then r allocation” teeth "Unoccupied elevator −” =12- shall be.

ANT) [Waiting time] teeth "You can wait." shall be.

Based on this fuzzy rule, the importance of the input is evaluated using the membership function fI (Figure 5), f + = 0.9, and the evaluation of a specific user is determined by the membership function fo (Figure 6).
As a result, fo=0.7 is obtained. A in the if part of the rule
ND represents the product, and the membership function value fR of this rule
becomes fn=f+Xfo=0.63.

The then part of the rule is to apply the value of fn to the membership function f of the elevator (Figure 7).
8% is found and this is taken as the permissible value for the degree of congestion in the car. Next, the value of fR is determined by the waiting time membership function fw (8th
Figure) is applied and 30 seconds is set as the allowable waiting time value.

In step 204, the allocation unit 2-2 assigns the permissible in-car congestion level of 38% and the permissible waiting time value of 30 seconds obtained above to the allocation unit 2-2.
and end the process. This process is activated when a change in elevator conditions occurs, such as human power or traffic flow mode.

The processing performed by the allocation unit 2-2 that receives the transmission is the same as in the first embodiment.

According to this embodiment, it is possible to provide a group management control device that allows even a building manager with no specialized knowledge of elevators to easily adjust the degree of difficulty of the temperature inside the car. In addition, in order to process ambiguous information involving humans such as importance evaluation, we can provide a flexible system by using fuzzy inference, and since it can be processed with a small number of rules, it does not require large-scale equipment or long hours. Great results can be expected with microcomputer software without the need for calculations.

The present invention uses two tolerance values: a tolerance value for the car interior temperature difficulty level and a tolerance value for the waiting time that changes in order to satisfy the tolerance value. It is also possible to use a first tolerance value such as boarding time, amount of information guidance, reservation rate, etc., and a second tolerance value for waiting time.For example, the following method can be used for the amount of information guidance. It is possible.The information guidance tolerance is the required time of 20 seconds for the information that you want to convey to the customers waiting in the hall, and the waiting time tolerance is 40 seconds.
When seconds are entered, ■: The car that meets the information guidance tolerance (in this case, the hall waiting time is 20 seconds or more) and the earliest that also satisfies the waiting time tolerance ■: Priority of the car that comes earliest Assign by. Here, in the information guide, if the tolerance value is not met, all information will not be conveyed even if it is close to the tolerance value, so it is meaningless, so here it is assigned to the earliest arriving machine as ■, It is also possible to forcibly leave the arriving aircraft unserviced up to the information guide tolerance. Using this method is effective for department stores, hotels, etc. that want to provide information about events.

Furthermore, it is possible to allocate not only two allowable values but also three or more allowable values; It is necessary to take measures such as setting limits on the permissible values themselves.

〔Effect of the invention〕

According to the present invention, since the assignment is performed based on the permissible value for the degree of difficulty of the car temperature, it is possible to perform individual group management control that can satisfy the user's needs. Further, by providing a waiting time tolerance value, there is an effect of preventing an extreme deterioration in efficiency due to excessive adjustment of the degree of difficulty in the car temperature. Furthermore, by providing a means for assisting in setting the allowable value, the present invention becomes a user-friendly group management control system that can be easily used even by users who do not have specialized knowledge of elevators.
