Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) [0001] The present invention relates to an elevator system that activates a multi-faculty elevator for a plurality of floors, and is represented by, for example, an intelligent building. Among the various office automation (A) systems in buildings like this, it relates to an elevator system that can effectively respond to large demand at the end of meetings, events, etc. by interlocking with the conference room / reception room reservation system. is there.

(Prior Art) In recent years, when multiple elevators are installed side by side, in order to improve the operating efficiency of elevators and the service to elevator users, the hall call on each floor is called. Group supervisory control systems are being used which allow responsive elevators to be reasonably and quickly assigned using small computers such as microcomputers.
In this system, when a hall call is generated, an optimum elevator serving the hall call is selected and assigned, and other elevators are prevented from answering the hall call.

In recent years, a group management control system of this type has a learning function, and uses learning data such as car call registration data measurement and loading / unloading load data measurement when responding to each hall call in real time. The inter-floor traffic volume is grasped and the average arrival time at each hall is grasped. Then, processing the measured data for each time zone based on the measured data, grasping the demand peculiar to each building, deciding the optimum number of machines when a hall call occurs, at work,
At the time of lunch, group management control such as setting of commuting hours and setting of the number of suspended machines for energy saving is performed.

In this group management control system, the above functions are usually distributed and processed by small computers such as a plurality of microcomputers.
The individual control device for single elevator control, which is connected in a slave relationship, is also made up of a small computer such as a microcomputer and is digitalized.Parallel transmission and serial transmission between the group management control system and individual control device Information is transmitted through transmission lines such as transmission.

Further, apart from this elevator group control system, recently, air conditioning, lighting, elevators, security, etc. using advanced information communication A system and computer,
The construction of intelligent buildings with a building management system for disaster prevention is drawing attention. In such an intelligent building, various types of processing are being decentralized and advanced in order to make terminals intelligent due to technological advances and to realize the needs of each department that have been left behind in a centralized manner. I'm doing it. A conference room / reception room reservation system exists as one system of such decentralization of the A system.

In this conference room / reception room reservation system, an operator makes reservations / inquiries about a conference room / reception room by inputting the date and time of holding a meeting / event or the number of participants from each terminal.

(Problems to be Solved by the Invention) However, the above group management control system for elevators and this conference room / reception room reservation system are completely separate systems, and information is exchanged with each other. There is no. For this reason, the elevator group management control system cannot read the information in response to a sudden large demand on the holding floor of the conference, event, etc. that occurs at the end of the conference, event, etc., and this large demand I couldn't cope enough with it. Moreover, since it is not possible to find regularity in these sudden large demands, even if the learning function added to the elevator group management control system as described above is used, no effect can be expected.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a building management system among various systems existing as a part of multi-functional processing decentralization as represented by an intelligent building. Various quantitative information is received from the conference room / reception room reservation system side by linking the elevator group management control system, which is one function of the system, and the conference room / reception room reservation system, which is one function of the A system. Accordingly, it is an object of the present invention to provide an elevator system having a function of predicting or recognizing the end of a conference / event in advance and sufficiently responding to a large demand generated at the end of the conference / event.

[Configuration of Invention] (Means for Solving Problems) The elevator system of the present invention makes a plurality of elevators active on a plurality of floors, and performs a predetermined evaluation calculation for a generated hall call. And an elevator group management control system for selecting an optimal elevator to make an allocation response,

They are connected to each other via a transmission line 14 for data transmission via a transmission control unit 13.

Various data including data transmitted through the transmission line 14 will be described with reference to FIG. Third
The figure shows a timer information storage database transmitted from the group management control unit 3 to the conference room reservation information processing unit 11. TMO, TD
Y, THR, and TMI indicate the current month, day, hour, and minute, respectively. That is, TMO = 0BH, TDY = 14H, THR = 06H, TMI = 11H at 6:17 on November 20.

(The H at the end indicates hexadecimal notation, and so on).

FIG. 4 shows a conference room number and its corresponding floor reference floor correspondence data table, which is held in the conference room reservation information processing unit 11. That is, RNO (n) indicates a room number such as a conference room / reception room, and RFL (n) indicates the corresponding floor corresponding to RNO (n).

For example, if the room number is 5 for the argument 3 of the array and the floor is the 4th floor, RNO (3) = 5 and RFL (3) = 4.

FIG. 5 shows a conference room reservation information storage database transmitted from the conference room reservation information storage database file 8 into the conference room reservation information processing unit 11. One conference room is assigned to one argument of the array. MFL (n) indicates the floor of the conference, MHR (n) and MMI (n) indicate the end time of the conference, and MNM (n) indicates the number of participants in the conference or the capacity of the conference room. .

For example, when storing a conference of 30 participants that ends at 16:50 on the 4th floor in the argument 3 of the array, MFL (3) = 04H, MHR (3) = 10H, MMI (3) = 32H, MNM (3) = 1EH.

Here, the conference holding floor data MFL is determined by referring to the table data RNO and RFL in FIG. 4 from the conference room number transmitted from the conference room reservation information storage database file unit 8. In addition, the data set in FIG. 5 is such that only the data for the current day is transmitted based on the time data shown in FIG. 3, and is sorted in order from the earliest end time,
In addition, by searching the database file 8 for storing the conference room reservation information in real time, it is possible to quickly respond to the change, cancellation, addition, etc. of the conference.

FIG. 6 shows the conference room reservation information processing unit 11 through the group management control unit 3.

In Fig. 6, FLR (n) indicates the floor where the conference is held, and NUM
(N) indicates the number of participants in the conference. These are the data sent by the conference room reservation information processing unit 11, and the data for the scheduled end time of the conference ± 15 minutes shall be set. Update meeting data with extended scheduled end time,
It is assumed that additions, etc. were made in real time.

A flowchart of the operation of the conference room reservation information processing unit 11 as described above is shown in FIG. The conference room reservation information is searched from the conference room reservation information storage database file unit 8 in the main control unit 9 of the conference room reservation system 7 (step S1), and when there is a change, addition, cancellation, etc. of the conference, FIG. Is reflected in the data table (steps S2 and S3), and only the data for 15 minutes before and after the conference end time is always present in the data table of FIG. 6 (steps S4 to S7).

FIG. 8 is a learning data storage data table in the learning control unit 4. This is a table for storing the ratio of the number of outflow personnel due to the end of the conference in the up and down directions from the conference end floor in the operation at the end of the conference.
The array arguments are 0 → 1F, 1 → 2F, and so on, where MUP is the up direction and MDN is the down direction. The data in these tables are updated each time the conference ends.

Now, with the end of the meeting on the 3rd floor, 50 people leaked from the meeting room, and if 10 of them got on the elevator in the up direction and 25 people got on the elevator in the down direction, the up direction = 10 / 50 x 100 = 20 (%) Down direction = 25/50 x 100 = 50 (%), and if MUP (2) = 18, MDN (2) = 36H until now, MUP (2) Therefore, the updated value of MDN (2) becomes MUP (2) = (24 + 20) / 2 = 16H MDN (2) = (54 + 50) / 2 = 34H.

If the reliability of the count value is low, the learning data will not be updated.

Next, the operation of the group management controller 3 will be described with reference to the flowcharts shown in FIGS. 9 and 10.

FIG. 9 is a flowchart showing the operation of the group management control unit 3. First, it is confirmed whether or not data exists on the data table shown in FIG. The fact that there is data on this data table means that the conference end time is near (step S11).

Next, after detecting a hall call on the floor existing on the FLR of FIG. 6 (step S12), the number of elevators allocated to the conference floor is determined according to the flow of FIG. 10, and the elevators are allocated (step S12). S13,14).

Also, there is only one elevator response to the conference floor,
In addition, when the elevator starts with 65% or more of the capacity, the next assigned elevator is to be opened, and otherwise the elevators are allotted to the conference floor and canceled (steps S15 to S18). That is, when all of the above-mentioned allocation of elevators to the conference floor is released, it is assumed that the supply of elevators for the demand generated by the personnel leaked at the end of the conference has ended, and And NUM data are cleared (step S1
9).

Here, the data of the learning data storage data table of FIG. 8 reflects the number of people who have boarded in the routine of the steps (S15-18).

Next, with reference to FIG. 10, a method for determining the number of elevators allocated to the above-mentioned conference ending floor will be described.

FIG. 10 is a flowchart showing a routine for determining the number of elevators allocated to the conference floor.

Now, the data read from the data table of FIG. 6 in steps S21 and S22 is FLR (1) = 04H, NUM (1) = 50H, and MUP (3) = 3CH, MDN (3) = 1EH. If the number of elevators is 12 (persons) and there is a hall call in the up and down directions on the 4th floor, the expected number of passengers in the up and down directions will be calculated as follows. (Step S2
3).

The number of elevators allocated in the up direction and the down direction is also calculated as follows (step S24).

Next, determine whether the total number of these allocated elevators is larger or smaller than the actual number of installed elevators.If the total number of allocated elevators is larger, the total number of elevators is equal to the actual number of elevators. The number of allocated elevators is proportionally distributed to calculate the actual number of allocated elevators (steps S25 to S27).

In the case of the above example, in step S25, the total number of allocated elevators = the number of elevators allocated in the UP direction + the number of elevators allocated in the DOWN direction = 4 + 2 = 6 <7 (the total number of elevators), and the number of allocated elevators is smaller,
The allocation calculation is completed here.

The number of elevators allocated in this way is the 9th
Given to step S14 in the flowchart of the figure,
Subsequently, group management control of the elevator will be executed.

[Effects of the Invention] As described above, according to the present invention, an elevator group management in which a plurality of elevators are activated for a plurality of floors and an optimum elevator is activated for a hall call. By linking the control system with the conference room / reception room reservation system in the building, the conference room / reception room reservation system can obtain quantitative data about various information required for elevator group management control online. As a result, it is possible to effectively allocate elevators even when there is a large demand due to the outflow of attendees at the end of the conference, and it is possible to improve elevator services.
