Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to an elevator group management control device for servicing a plurality of elevators to a plurality of floors, and a CRT display device is set between the group management control device and the group management control device. The present invention relates to an elevator group supervisory control device that is connected via a transmission line to enable a man-machine interface.

[Technical background of the invention] In recent years, when a plurality of elevators are arranged in parallel, an elevator that responds to a hall call on each floor in order to improve the operation efficiency of the elevator and the service to the elevator users. A group supervisory control device is used which allocates (responders) reasonably and promptly by using a small computer such as a microcomputer. That is, when a hall call occurs, select an elevator that is most suitable for handling the hall call, assign an elevator that should respond to the hall call early, and
Other elevators try not to answer the hall call.

In such a group management control device, a device with a learning function has recently appeared, and in real time, measurement data of car call registration floor data at each hall call response,
The inter-floor traffic volume and the average arrival interval at each hall are being grasped by measuring the loading and unloading load data.

Then, based on the above measurement data, this measurement data is processed for each time zone, the demand peculiar to each building is grasped, and the optimum number of machines when the hall call occurs is decided, when going to work, at lunch, when leaving work, etc. It is directly applied to the group management control such as the setting of, the setting of the distributed standby zone at the time of the outage, the setting of the number of suspended units due to energy saving measures.

[Problems of Background Art] Therefore, since the group management control device described above is fully automatic, it is almost impossible for the customer to change the program operation by manual setting. However, depending on the customer, there is a case where, for example, in order to save energy during a certain period of time, even if the service is reduced, the number of suspended machines may be increased. Further, there is a case where it is desired to manually set the specific time zone in advance, such as when it is predicted in advance that the demand for a specific floor will increase.

In such a case, it is necessary to change the program itself, and it takes a lot of time and labor for the storage device of the microcomputer, such as programmable read only memory (PROM) conversion.

Further, when determining the manual setting by the customer as described above, it is indispensable to grasp the traffic demand of each time zone as back data, but some statistical data is stored in the storage device of the group management control device. However, it requires a large-scale device by connecting a measuring device to the outside, and moreover, it takes a considerable amount of time from measurement to the actual output in the form of statistical processing, which is timely for the customer. It is impossible to grasp the data of.

In addition, when the user inputs setting data, it is important to understand quantitatively how the set value that is input affects the system of the entire group management control device and how effective it is. , It is difficult to determine an appropriate value that is valid only by the user because it differs depending on demand, time, etc., and it is practically difficult to feed back the user's intention to the group management control device. It is difficult to convey the user's intention without distrusting the user.

[Object of the Invention] The present invention has been made in view of the above circumstances, and the parameters in the program can be changed manually based on the message of the display device, and the traffic measurement result and demand in each building can be displayed. An object of the present invention is to provide an elevator group management control device that is capable of grasping data on the user side and can improve service.
