Description

  The present invention relates to an elevator car control method, and more particularly, to an elevator control system capable of optimizing comfort, convenience, safety, and energy efficiency in accordance with passenger conditions.

  An elevator is an automated driving system that registers the previous floor where the user goes and opens and closes the door, and is different from a transportation system in which operators such as trains and airplanes are interposed. For this reason, in an elevator, ensuring the safety of automatic driving is the top priority, and passenger convenience and safety are not taken into account so much, and a method for dealing with an abnormality as disclosed in Japanese Patent Application Laid-Open No. 2007-230732 Was just about to be devised.

  On the other hand, sensing technology using cameras etc. has greatly advanced in recent years, and facial recognition and age / gender recognition have been put into practical use.For example, age determination in cigarette vending machines and customer age in digital signage It is used for content switching according to gender.

  In the behavior detection device described in Patent Document 1, although it is possible to ensure the safety of passengers by real-time behavior detection against the occurrence of passenger abnormality in the elevator, Improvements in convenience and security were not considered.

  As elevators become more widespread, there are increasing opportunities for elderly people to use, and it is easy for events such as being caught between doors to occur due to a decline in physical ability. It is necessary to improve convenience and safety for these users.

  In addition, there are requests from elevator users to improve the feeling of blockage in the closed car, and to resolve anxiety during boarding, although announcements and music are said to be effective, but depending on the situation in the car If announcements and music cannot be selected, the effect is small.

  The present invention has been made in view of these problems, and an object of the present invention is to recognize a situation in a car using a camera image and to provide an optimal service for passengers according to the result. It is in providing the elevator control system which can provide.

  To achieve the above object, an elevator having an elevator control device that performs elevator speed control and operation control and a car control device that performs car door opening / closing speed control, in-car announcement control, and in-car lighting control is provided. On the other hand, a camera and a recognition means for discriminating the number of passengers, age, and sex from the image of the camera are provided in the car. The recognition means detects elderly passengers, detects unmanned conditions, detects single passengers, detects two passengers and three or more passengers, and the car control device responds to the detection results of the recognition means. Provide optimal operation for passengers.

For example, when an elderly passenger is detected, the door closing speed is reduced, and when an unmanned passenger is detected, the illumination, announcement, and blower fan in the car are stopped. When a single passenger is detected, an open-minded music or question announcement is made, and when a two-person passenger is detected, an announcement, video and music effective for deterring sexual crimes are output in the car, and more than three When the boarding is detected, an announcement, video and music effective for alleviating the feeling of blockage in the car are output to the car.

  ADVANTAGE OF THE INVENTION According to this invention, not only can an elevator provide a moving service to a passenger, but also convenience, safety, and energy efficiency can be provided. In other words, it is possible to increase the convenience, comfort, and security of getting on and off by lowering the door closing speed for elderly people who have become less agile. In addition, by changing announcements, lighting, and music in the car depending on the number of passengers, it is possible to suppress the occurrence of crime by providing announcements and music that have the effect of subduing the mind when two people ride.

  In addition, by providing relaxing announcements and music when three or more passengers are on board, it is possible to eliminate unnecessary obstruction and provide a comfortable ride.

It is a whole block diagram of 1st Embodiment in the elevator control system of this invention. It is a code table which shows an example of a recognition result code and its contents. It is a code table which shows an example of a car control code and its contents.

  Hereinafter, an embodiment related to an elevator control system of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram of an elevator control system according to the present invention.

Reference numeral 1 denotes an elevator control device that controls the entire elevator, and drives a hoisting machine (not shown) according to a destination floor instruction from a hall button (not shown) or a push button installed on the car. Raise and lower. Reference numeral 20 denotes a car, and each device within the broken line 20 is provided in the car. Reference numeral 2 denotes a car control device that controls various devices of the car. The main devices to be controlled are a door control device 4 that opens and closes a door, a lighting control device 5 that controls lighting, announcements and music (background music) There is an announcement device 6 that performs control.

  Reference numeral 3 denotes recognition means for recognizing the situation of passengers in the car, and recognizes the situation of passengers in the car using the camera 7 and other sensors 8 and the elevator status signal from the elevator control device 1. As the sensor 8, a human sensor, a thermopile sensor, a voice microphone, a Sh acceleration sensor, or the like can be used. The elevator status signal includes the door opening / closing status of the car. As a passenger situation recognition algorithm, there is a method of extracting passengers based on background difference and the like, but since the algorithm itself is not particularly important in the implementation of the present invention, detailed description thereof is omitted.

  The recognition result in the recognition means 3 is encoded as shown in FIG. 2 and sent to the elevator control device 1 via the identification result signal 10. The elevator control device 1 generates the car control code shown in FIG. 3 by adding the state of the entire elevator to the identification result signal 10. For example, during the dedicated operation or maintenance operation, normal car control is prioritized without generating a car control code. The car control code is transmitted to the car control device via the control signal line 11, and the car control device 3 operates the door control device 4, the lighting device 5, and the announcement device 6 according to the situation of the passengers in the car according to the control signal 11. Control to do.

  For example, when an elderly person gets on alone, the recognition means 2 generates the recognition result code [1, 0, 1] using the image of the camera 7 installed in the car. The recognition result code is transmitted to the elevator control device 1 via the identification result signal 10. The elevator control device 1 generates a car control code [0, 0, 0, 1] while the car is moving, and transmits the car control code [0, 0, 0, 1] to the car control device 3 via the car control signal 11. The car control device 3 generates an announcement to alleviate the feeling of blockage of the car according to the car control code [0, 0, 0, 1].

  Thereafter, the elevator control device 1 generates a car control code [1, 0, 0, 0] when the car arrives at the destination floor, and transmits it to the car control device 3 via the car control signal 11. In accordance with the car control code [1, 0, 0, 0], the car control device 3 extends the door opening time and reduces the door speed to support the elderly person easily getting out.

  As described above, according to the present invention, convenience, comfort, and a sense of security for passengers can be enhanced by appropriately changing door control, announcement, music, and lighting according to the situation in the car. Moreover, the power consumption of an elevator can be suppressed.
