elevator system

Abstract

The invention provides an elevator system which can prevent passengers from increasing frequency of longtime waiting, and from waiting for a long time, reduces unnecessary driving of the elevator, and saves power. The elevator controls an elevator car (010) running among a plurality of floors of a building. The elevator system is provided with a passenger detection device (001) and a car position sensor (003), the passenger detection device is arranged at the position far away from the specified distance of an elevator hallway to detect passengers, the car position sensor detects the height position of the elevator car, when the passenger detection device (001) detects the passengers before the elevator car (010) is arrived at the elevator hallway, the driving speed of the elevator car (010) is determined by the height position of the elevator car (010) detected by the car position sensor (003) based on the specified distance and the detected time of the passengers.

Description

technical field [0001] The present invention relates to an elevator system for controlling the operation of an elevator car, especially an elevator system suitable for suppressing unnecessary operation to realize energy saving. Background technique [0002] In order to effectively utilize the living area in the building and reduce the installation area of ​​elevators that do not directly contribute to the living area, it is necessary to reduce the number of elevators to the minimum necessary range. In addition, in order to save energy and electricity, it is necessary to reduce the number of elevators in operation. At this time, it is necessary to perform operation control according to the situation of the passengers. [0003] For example, a technology is disclosed in Patent Document 1, which reflects whether the passenger is an elderly or weak passenger as the passenger situation in the operation control, and when the elderly and weak passenger approaches the elevator lobby...

AI Technical Summary

Problems solved by technology

[0011] Among the above-mentioned conventional technologies, the technology disclosed in Patent Document 1 has a high possibility of excessively slow control operation, so there is a possibility that the number of occurrences of a long wait may increase, or an extremely long wait may occur.

In addition, because it can only perform slow control operation for the floors that have been determined to stop, the application range is narrow

[0012] In addition, in the technology disclosed in Patent Document 2, if there are other hall calls, if the elevator passes the floor immediately after the automatic login, it needs to be judged when the elevator returns to the floor again. Only specific individuals who are out can take the elevator, resulting in a very long waiting time

Moreover, since the identified person does not necessarily take the elevator, unnecessary automatic login may also occur, resulting in a decrease in the operating efficiency of the elevator.

[0013] The technology disclosed in Patent Document 3 has the same problem. Since not all the detected people take the elevator, when this technology is used while there are other hall calls, the waiting time may become very long.
