Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator system that operates a plurality of elevators for a plurality of floors. The present invention relates to an elevator system that can effectively cope with heavy snow conditions at the end of meetings, events, etc. by linking with office automation (OA) systems in various buildings, especially with conference room and reception room reservation systems.

(Prior art) In recent years, when multiple elevators are installed in parallel, in order to improve the operating efficiency of the elevators and improve the service to elevator users, microcomputers have been developed to control the elevators that respond to hall calls on each floor. Group management control systems that use small-sized computers such as the above to perform rational and quick allocation have come into use.

In this system, when a hall call occurs, the most suitable elevator to service the hall call is selected and assigned, and other elevators are not allowed to respond to the hall call.

Recently, among such group management control systems, systems with a learning function have appeared, and learning functions such as measuring car call registration data when responding to each hall call in real time, and measuring data on boarding and alighting loads, etc. Measures are being taken to ascertain inter-floor traffic m in the evening and the average time between arrivals at each hall.

Then, based on the above measurement data, the measurement data is processed for each time period to understand the unique demand of each building, determining the appropriate R machine when a hall call occurs, when dispatching, during lunch, during commuting hours, etc. Group management control is performed, such as setting the number of idle machines to save energy.

In this group management control system, the above functions are normally distributed and processed by multiple small computers such as microcomputers, and the group management control system and master
The individual controllers for single elevator control that are connected as slaves are also constructed from small computers such as microcomputers and are digitized, and parallel transmission or serial transmission is used between the computers of the group management control system and the individual controllers. Information is transmitted through transmission lines such as transmission lines.

Furthermore, in addition to this elevator group management control system, recently, intelligent buildings have been constructed that are equipped with advanced information communication OA systems and computer-based building management systems for air conditioning, lighting, elevators, security, and disaster prevention. Attention has been paid. In these intelligent buildings, various processes are being decentralized and becoming more sophisticated in order to make the terminals more intelligent due to technological advances and to realize the needs of each department that have been left behind in the centralized system. I've been doing it. One system that exists as a decentralized 0Δ system is a conference room/
This is a reception room reservation system.

This conference room/reception room reservation system allows A-berators to make reservations/inquiries about conference rooms/reception rooms by inputting the date and time of a meeting/event, number of participants, etc. from each terminal.

(Problems to be Solved by the Invention) However, the above-mentioned elevator group management control system and this conference room/reception room reservation system are completely separate systems, and information is not exchanged with each other. As a result, when a sudden large demand occurs on the floor where a meeting/event is being held at the end of a meeting/event, etc., the elevator group management control system is unable to read the information. I couldn't deal with it adequately. Further, since no regularity can be found in these sudden large demands, no effect could be expected even if the learning function added to the elevator group management control system as described above was used.

The present invention was made in view of these conventional problems, and its purpose is to improve the building management system, which is one of the various systems that exist as a part of multifunctional processing decentralization such as intelligent buildings. The elevator group management control system, which is one of the functions, and the -R of the OA system.
By linking with a conference room/reception room reservation system that has the ability to receive various quantitative information from the conference room/reception room reservation system, it is possible to predict the end of a meeting, event, etc. in advance, or The objective is to provide an elevator system that is fully capable of responding to the large demand that occurs at the end of meetings, events, etc.

[Structure of the Invention] (Means for Solving the Problems) The elevator system of the present invention operates a plurality of elevators for a plurality of floors, and performs a predetermined evaluation calculation for generated hall calls. An elevator group management control system that selects and responds to the assignment by selecting the most suitable elevator;
The conference room/reception room reservation system in the building and the conference room/reception room reservation system
A conference room that retrieves conference room reservation information stored in a reception room reservation system, predicts demand that will occur at the end of a meeting, event, etc., and provides allocation information for the required number of elevators to the elevator group management control system. It is equipped with a reservation information processing section.

(Function) In the elevator system of the present invention, the conference room reservation information such as the conference T number, the date and time of the conference, and the number of participants stored in the conference/reception room reservation system is imported into the conference room reservation information processing section. The floor where the meeting will be held, the end time of the meeting, and the number of people who will flow out due to the end of the meeting are determined in advance and given to the elevator group management system, and at the end of the meeting, the number of elevators commensurate with the demand is assigned to the floor concerned. installed and put into service.

Car call prediction data, energy saving command data, distributed standby data, specific floor data, and traffic pattern data are calculated and determined, and the command data is transferred to the group management control section 3 and hall call control section 2.

The conference room/reception room reservation system 7 includes a main control section 9 that leaks the database file section 8, and terminal input devices ff10a and 1 for inputting conference room reservation information to the monarchy W section 9.
It is composed of 0b, .

The main control unit 9 includes terminal input devices 10a and lOb.

When a conference reservation application is input through ..., it finds an empty conference room and makes a reservation.
Reservation information such as the determined conference room number, date and time, and number of attendees is registered in the database file section 8.

The conference room reservation information processing unit 11 is composed of a small computer such as a microcomputer, and is connected to the group management control unit 3 and the database file unit 8, and is configured to process conference room reservation information input from the database file unit 8. It performs a series of processes such as determining the floor where the meeting 1 will be held, transmits the data to the group management control unit 3, and serves as an interface between the conference room/reception room reservation system 7 and the elevator group management control system 1. . The elevator group management system 1 and the conference room/reception room reservation system 7 are connected online via the building LAN 12.

Next, the operation of the elevator system will be explained with reference to FIG. 2 and the following figures.

As shown in FIG. 2, between the group management control section 3 and the conference room reservation information processing section 11, and between the conference room reservation information processing section 11,
A transmission line 1 for data transmission is connected to the database file section 8 for storing conference room reservation information via a transmission control section 13.
They are connected to each other through 4.

Various data including data transmitted through this transmission line 14 will be explained based on FIG. 3 and subsequent figures. In FIG. 3, the conference room reservation information processing unit 11 is
This is a database for storing timer information transmitted to. T
MO, TDY, TI-IR, and TMI indicate the current month, day, hour, and minute, respectively. i.e. November 20th 6
At 17 minutes, TMO=OB+-1.

TDY=14H.

T HR-068.

TM? =118. (T1 at the end indicates hexadecimal notation, and the same applies hereinafter).

FIG. 4 is a data table for correspondence between conference room numbers and their corresponding floors and reference floors, which is stored in the conference room reservation information processing unit 11. That is, RNO(n) indicates the room number of a conference room, reception room, etc., and RFL(n) indicates the corresponding floor corresponding to RNO(n).

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

FIG. 5 shows a conference room reservation information storage database transmitted from the conference room reservation information storage database file 8 to the conference room reservation information processing section 11. One conference room is assigned to one array argument. MFL (
n) indicates the floor where the meeting will be held, and Ml-IR(n) and M
MI(n)r Indicates the meeting end time, ・MNM (n)
indicates the number of participants in the meeting or the capacity of the conference room where the meeting is held.

For example, when storing a meeting with 30 participants that ends at 16:50 on the 4th floor in argument 3 of the array, MFL (3)
-04H.

MllR(3)=1　0f−1゜ MMI(3) = 32 t1.

MNM(3)=161-1 becomes.

Here, the conference floor data MFL is determined from the conference room number transmitted from the database file section 8 for storing conference room reservation information by referring to the table data RNO and RFL in FIG. In addition, the data set in Figure 5 shall be transmitted based on the time data shown in Figure 3, and only the data for the day will be transmitted, and will be sorted in descending order of ending time, and will be sent to the conference room in real time. By searching the reservation information storage database file 8, it is possible to quickly respond to changes, cancellations, additions, etc. of meetings.

FIG. 6 shows group management a, I from the conference room reservation information processing unit 11.
This is a data table within the group management ν control unit for data transmitted to the IrID unit 3. In this embodiment, it is assumed that there is one conference room on the first floor.

In FIG. 6, FLR(n) indicates the floor where the conference is held, and NLIM(n) indicates the number of participants in the conference. These are data sent by the conference room reservation information processing section 11, and data for ±15 minutes of the scheduled end time of the meeting is set, and data that is 15 minutes or more past the scheduled end time of the meeting is cleared.

It is also assumed that updates and additions to conference data whose scheduled end time has been extended are performed in real time.

FIG. 7 is a flowchart showing the operation of the conference room reservation information processing section 11 as described above. Search for conference room reservation information from the conference room reservation information storage database file unit 8 in the main control unit 9 of the conference room reservation system 7 side (Step Sl), and when there is a change, addition, cancellation, etc. of the conference, the process shown in FIG. This is reflected in the data table (step 82.S3), and only data for 15 minutes before and after the meeting end time always exists in the data table of FIG. 6 (steps 84 to 87).

FIG. 8 is a data table for storing learning data in the learning control section 4. This is a table for storing the ratio of outflow personnel due to the end of the meeting in the upward and downward directions from the meeting end floor during the meeting end operation.

The array arguments are O→1F, 1→2F, etc., where MUP indicates the proportion of demand in the up direction and MDN indicates the proportion of demand in the down direction. Furthermore, the data in these tables is updated every time the meeting ends.

Now, when the meeting on the third floor ends, 50 people leave the conference room, and if 10 of them get on the up elevator and 25 get on the down elevator, then up direction - 10150x100 =20 (%) Dow:
/ direction = 25150x100 = 50 (%), and until now, MUP (2) = 18. If MDN (2) = 36H, the update value of MUP (2) and MDN (2> is MLIP (2) = (24 + 20) / 2 = 16HMD
N (2) = (54+50)/2=3
4 becomes 1.

Note that if the reliability of the count value etc. is low, the learning data will not be updated.

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

FIG. 9 is a flowchart showing the operation of the group management control 2Il group 3. First, it is checked whether data exists on the data table shown in FIG. The presence of data on this data table means that the end time of the conference is near (step 511).

Next, after detecting a hall call on a floor existing on the FLR in FIG. 6 (step 512), the number of elevators to be allocated to the conference floor is determined according to the flow in FIG. 10, and the elevators are allocated (step 512). 813.1
4).

In addition, the elevators to the conference floor respond one at a time.
Furthermore, if the elevator departs with 65% or more of the elevator capacity, the doors of the next assigned elevator will be opened; otherwise, all elevator assignments to conference floors will be canceled (
Steps 815-818). In other words, once all the elevators have been allocated to the conference floor mentioned above, the supply of elevators for the amount of time generated by the outflow of population due to the end of the conference is deemed to have ended, and the Clear the data of FLR and NIJ~1 (step 519).

Here, the number of people who boarded the vehicle in the routine of the above steps (S15 to S18) is reflected in the data in the data table for storing character-shaped data in FIG.

Next, using FIG. 10, a method for determining the number of elevators to be allocated to the above-mentioned conference end floor will be explained.

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

Now, the data read from the data table in FIG.
H.

NUM (1) = 50H and MUP (3) = 3C to 1.

When MDN (3) = IEl-1 and elevator capacity = 12 (people), if there is a hall call for the up direction and the down direction on the 4th floor, the number of people boarding the elevator for the up direction and the down direction is The expected number of people is calculated as follows (step 523).

Expected boarding value in the up direction, expected number of passengers in the down direction, etc. Also, the number of elevators to be allocated in the up direction and the down direction is calculated as follows (step 524).

Number of elevators assigned in UP direction Number of elevators assigned in UP direction Number of passengers in the UP direction Number of elevators in one direction υ Number of elevators in the DOWN direction Number of passengers in the direction Next, determine whether the total number of these assigned elevators is greater or less than the actual number of installed elevators. However, if the number of allocated elevators is larger, the number of allocated elevators is proportionally distributed in the up direction and down direction so that the total sum is equal to the actual number of elevators, and the actual number of allocated elevators is totaled (steps 825 to 825). 527).

In the case of the above example, in step 825, the total allocation phrase is number of elevators = number of elevators allocated for LJPh + number of elevators allocated for DOWN direction υjsf = 4 + 2 =
6 7 (total number of elevators), and since the number of allocated elevators is smaller,
At this point, the allocation calculation ends.

The number of elevators calculated in this way is
This is applied to step S14 in the flowchart of the figure, and the group management control of the elevators is subsequently executed.
