Description

The present invention relates to an elevator group management control device for activating a plurality of elevators on a plurality of floors, and particularly to an intelligent building. It concerns an elevator system.

(Prior Art) In recent years, when a plurality of elevators are installed side by side, in order to improve the operation efficiency of the elevators and the service to the elevator users, an elevator that responds to a hall call on each floor is provided with a microcomputer or the like. The rational and prompt allocation is performed by using the small computer. That is, when a hall call is generated, an optimal elevator serving the hall call is selected and assigned, and other elevators are prevented from responding to the hall call.

In recent years, group management control of this type, which has a learning function, has appeared between floors based on learning data, such as measurement of car call registration data and data of entry / exit load when responding to each hall call in real time. The amount of traffic and the average time between arrivals at each hall have been grasped.

Then, processing the measured data for each time zone based on the measured data, grasping the demand peculiar to each building, determining the optimal number of machines when a hall call occurs, setting work hours, lunch, leaving time, etc. It directly responds to the group management control such as setting of the distributed standby zone at the time of off-hours and setting of the number of suspended machines for energy saving.

The group management control device normally performs distributed processing of the above functions by a plurality of small computers such as microcomputers, and also has a single elevator control unit control device connected in a master / slave relationship with the group management control device. It is composed of a small computer such as a microcomputer and is digitalized, and high-speed information is transmitted by a transmission line such as serial transmission between computers of a group management control device and a single control device.

As described above, in an elevator system that performs group management control, the entire system is complicated and digitalized, such as an increase in software ratio of control by a microcomputer and high-speed information transmission between computers.

Under such circumstances, conventionally, the unique information about each building that can be effectively used in the elevator system is
Since an elevator system, which is a closed system inside the building, is mainly implemented, the data collection means is limited and the types of data that can be effectively used are limited, so that there is a limit to the use for elevator operation control.

For example, considering a service for visiting important customers in an elevator system, the response to this service is
The halls or monitoring boards support dedicated hall calls and are not linked to the information system that manages reception / guidance in the building, so manual guidance / operation by the reception / guidance staff is required. A sufficient effect could not be obtained because the operation of the elevator system may be adversely affected by the operation of a dedicated call by another person.

(Problems to be solved by the invention) As described above, since the conventional group management control elevator device is not configured to make use of the management information on the building side, in the case where a dignitary visits, there is a special case for the dignitary. The call generation button is provided so that the car can be preferentially called by pressing the button. Therefore, a general customer may push this, which often disturbs the group management control, which is a problem.

On the other hand, with the advent of the so-called intelligent building, which started in the United States and is developing mainly in urban areas in recent years, the diversification of building systems has progressed, and the information and communication systems of buildings have become complete. Centered around office automation (hereinafter abbreviated as OA) systems, OA support services in buildings have been developed, information data unique to each building has been prepared, and information communication has been carried out via a local area network (LAN) in the building. It is supposed to be done.

The information data includes a large amount of unique information data regarding each building that can be effectively used centering on the group management control function in the elevator system. However, in the past, such information data unique to each building has not been utilized, and the elevator system collects data only from inside the elevator system centering on the car load data as described above. There was a limit to the amount and it was difficult to connect to other various devices.

However, with the intelligentization of the building, it became easier to systematize information communication in the building, and it became possible to connect the computer that manages the OA system of each building and the elevator system online with the building LAN, Sharing of information data processed by software packages supporting OA functions is becoming a feasible stage.

Therefore, the object of the present invention is to find the OA inside the building.
Reception / guidance system and building LAN, which are one management system
A group management control elevator device that can be connected to a customer service center to implement an elevator specific person service operation function in conjunction with the operation of the reception / guidance system as a response to important customer visits based on the above information. To provide.

[Structure of the Invention] (Means for Solving Problems) In order to achieve the above object, the present invention has the following structure. That is, in a group management control elevator device that activates a plurality of elevators for a plurality of floors, performs a predetermined evaluation calculation for a generated hall call and selects and responds to an optimal elevator, it is connected to a building local area network. A control for connecting to the building management computer having a system for managing reception / guidance information and the local area network in the building, and obtaining the reception / guidance information to execute a predetermined operator service operation function. It is configured by providing means.

(Operation) In such a configuration, the control means of the group management control elevator device is connected to the building management computer via the local area network in the building, and is used for building management, which is the information of the building management computer. You can get reception / guidance information. Then, based on this information, the control means timely realizes the specified person service driving function when the important customer visits. Therefore, it becomes possible to carry out various operations that were difficult only from the internal information of the elevator system without any special manual operation input for that, and it would be confusing to the whole system. You will be able to improve.
