Description

  The present invention relates to an elevator system.

  An elevator is a public facility used by an unspecified number of people. However, since the elevator car is in a closed room, it has a characteristic that it is easily targeted by criminals as a crime scene. Therefore, in many elevator systems, it is normal to adopt a configuration in which a security camera is installed in the car. In this case, a configuration may be employed in which a movable security camera is employed in order to improve the crime prevention effect, or a display that displays the state of the car room is installed (see, for example, Patent Document 1).

However, installing a security camera in the car is very effective for improving the security effect, but it may impair the privacy of general elevator users. In particular, it is said that elderly people often feel uncomfortable when they are monitored by security cameras. Therefore, considering the balance between the aspect of maintaining the crime prevention effect and the aspect of respecting privacy, it is possible to have a configuration in which the security camera is shielded when the number of passengers in the car is one and the shield is released when there are multiple passengers. (For example, refer to Patent Document 2).

  By the way, depending on the kind of building, an elevator user may be limited to some extent. For example, in nursing homes and nursing homes, elevator users are usually tenants, relatives and friends of residents, staff of facilities, etc., and there are usually few opportunities for outsiders to use them. is there. In addition, in buildings where a strict security system is constructed, it is usually impossible for outsiders to enter the building without permission.

  In the case of a building where the number of elevator users is limited to some extent, it is considered that there is no problem in placing a weight on respecting privacy rather than maintaining the crime prevention effect in order to form a comfortable living space. In this regard, the system according to Patent Document 1 focuses on improving the crime prevention effect, and since it does not particularly take into consideration respect for privacy, it cannot be said that it is suitable for the above-described buildings.

  On the other hand, it can be said that the system according to Patent Document 2 takes some consideration not only for the crime prevention effect but also for respect for privacy. However, privacy is only considered when there is a single elevator user in the car, and when there is a passenger in the car, it is subject to surveillance by the security camera, so privacy is still sacrificed. Become.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an elevator system in which sufficient consideration is given to respecting the privacy of the elevator user in a building where the elevator user is limited to some extent. It is said.

  As a means for solving the above problems, the present invention detects a load movement situation and a load distribution situation at the time of movement or stationary of a passenger in a car or equipment accompanying the passenger, which is attached to the bottom of the car floor. Based on the detection information from the in-car load status detecting means and the in-car load status detecting means, based on the monitoring information from the in-car usage status monitoring means and the in-car usage status monitoring means, And an elevator operation control means for controlling the operation of the elevator.

  ADVANTAGE OF THE INVENTION According to this invention, when it is a building where an elevator user is limited to some extent, the elevator system in which sufficient consideration was made | formed with respect to the privacy of the elevator user can be provided.

  FIG. 1 is a configuration diagram of an elevator system according to an embodiment of the present invention. A car floor 2 is laid in the passenger car 1, and a passenger M1 and a wheelchair user M2 are on the car floor 2. And the security camera which is often seen in the normal elevator system is not installed in the interior of the car 1.

  A pressure-sensitive rubber 3 as a load sensor is attached to the bottom surface side of the car floor 2. The pressure-sensitive rubber 3 can detect the load movement situation and the load distribution situation when the passenger M1 and the wheelchair user M2 move on the car floor 2 or are stationary. The distribution state of the distortion generated due to the load of the passenger M1 and the wheelchair user M2 transmitted in this manner is visually shown on the surface.

  A camera 4 with a wide-angle lens as an imaging unit is disposed below the pressure-sensitive rubber 3. The wide-angle lens-equipped camera 4 is for imaging the distribution state of distortion that appears visually on the surface of the pressure-sensitive rubber 3. The pressure sensitive rubber 3 (load sensor) and the wide angle lens-equipped camera 4 (imaging means) constitute a car load condition detecting means 5.

  Image data (detection signal) from the wide-angle lens-equipped camera 4 is sent to the in-car use state monitoring means 7 of the elevator control device 6. The in-car use status monitoring means 7 performs an analysis process such as comparing the sent image data with a pattern held in advance, and the number of passengers in the car 1 and the equipment accompanying the passengers (for example, , Wheelchairs, baby carriages, canes, etc.), empty space in the car 1, and the behavior of passengers, etc., and the usage status in the car 1 is monitored using the estimation results.

  The elevator control device 6 is also provided with an elevator operation control means 8 and a monitoring information storage means 9. The elevator operation control means 8 controls the operation of the elevator based on the monitoring information from the in-car usage status monitoring means 7. The monitoring information from the in-car usage status monitoring means 7 and the image data from the in-car load status detection means 5 (the camera 4 with the wide-angle lens) are stored in the monitoring information storage means 9.

  Next, a specific example of the operation of FIG. 1 will be described. In this example, it is assumed that the building is a 5-story apartment house. Initially, the car 1 is waiting for door opening on the first floor (entrance floor) and there are no passengers in the room. However, since the passenger M1 has entered the hall, the car 1 performs a door closing operation. Assume that the passenger M1 presses a car call button (not shown) on the fourth floor, which is the destination floor.

  At this time, the load of the passenger M1 transmitted to the pressure-sensitive rubber 3 through the car floor 2 is transmitted along with the walking motion of the passenger M1. Therefore, the strain distribution state according to the walking pattern of the passenger M1 appears visually on the surface of the pressure-sensitive rubber 3. The visually appearing distribution situation is photographed by the camera 4 with a wide-angle lens, and the image data is sent to the in-car utilization situation monitoring means 7.

  The in-car usage status monitoring means 7 performs an analysis process based on a comparison between the image data from the wide-angle lens-equipped camera 4 and a previously held pattern. For example, it can be estimated that the passenger M1 is an adult boy and the number of passengers who have boarded is one person from the stride and distortion shape and the number of patterns in the walking pattern.

  Next, the elevator operation control means 8 registers the fourth floor car call by the passenger M1, and then starts the traveling of the car 1. Thereafter, the elevator operation control means 8 responds to the hall call from the second floor, stops at the second floor, and causes the car 1 to perform the door opening operation. Then, it is assumed that the wheelchair user M2 enters the car 1 from the second floor hall and presses the car call button on the fifth floor, which is the target floor.

  At this time, the load of the wheelchair user M2 transmitted to the pressure-sensitive rubber 3 through the car floor 2 is transmitted along with the rotation operation of the wheel of the wheelchair. Therefore, the distribution state of the distortion according to the continuous rotation pattern of the wheelchair wheel appears visually on the surface of the pressure-sensitive rubber 3. The visually appearing distribution situation is photographed by the camera 4 with a wide-angle lens, and the image data is sent to the in-car utilization situation monitoring means 7.

  The in-car usage status monitoring means 7 performs the analysis process based on the comparison between the image data from the wide-angle lens-equipped camera 4 and the pattern held in advance, as before. For example, it is presumed that one wheelchair user (in this case, “the type of equipment attached to the passenger” is a wheelchair) is boarded from the continuous rotation pattern of the wheels and the number of patterns. it can.

  Next, the elevator operation control means 8 registers the fifth floor car call by the wheelchair user M2, and then starts the traveling of the car 1. At this time, the elevator operation control means 8 further determines whether or not there is sufficient free space in the car 1 to allow a new passenger to enter based on the monitoring information from the in-car use status monitoring means 7. Determine.

  In the present example, the passengers in the car 1 are only the passenger M1 and the wheelchair user M2, so that there is sufficient free space, but in the case of other passengers, for the wheelchair that occupies a large space, In some cases, there is no available space despite the small number of passengers. In such a case, even if there is a hall call on the third floor, the elevator operation control means 8 performs control so as to pass the third floor as it is without responding to it.

  Thereafter, the car 1 stops on the fourth floor and the passenger M1 gets off, and then stops on the fifth floor and the wheelchair user M2 gets off. At this time, the elevator operation control means 8 extends the door opening time to a long time set for wheelchair users not only when the fifth floor is stopped but also when the fourth floor is stopped. That is, the elevator operation control means 8 performs the door opening / closing control by setting the door opening time in all the stop floors as the set time for the wheelchair user until the wheelchair user M2 gets on the car 1 and gets off. To do. In this example, since there are only two passengers, it is possible to determine that the destination floor of the wheelchair user M2 is the fifth floor, but when there are many passengers, the purpose of the wheelchair user M2 is This is because it is difficult to accurately determine the floor.

  In the elevator system according to this embodiment described above, since no security camera is installed in the car 1, the privacy of the passenger is respected, and the passenger can be prevented from feeling uncomfortable. In addition, since the security camera is not installed, a secondary effect that the interior of the car 1 is also neatly designed is derived.

  Furthermore, in a normal elevator system, only one elevator out of a plurality of elevators is equipped with a wheelchair landing call button and a wheelchair car call button. However, in the elevator system according to this embodiment, As long as the wheelchair user is in the car without the wheelchair call button, the door opening time of the elevator door is extended. Therefore, it has a barrier-free configuration that eliminates the inconvenience of wheelchair users.

  On the other hand, in the elevator system according to the present embodiment, since no security camera is installed, it is not possible to give a psychological pressure to a criminal or a suspicious person, and the interior of the car 1 can be directly viewed. Since it cannot be projected, it seems that a sufficient crime prevention effect cannot be obtained at first glance. However, since the elevator system according to the present embodiment is assumed to be applied to a building where elevator users are limited to some extent, these points are not considered to be a serious problem.

  Also, the elevator system according to the present embodiment can be provided with a certain amount of crime prevention function. For example, there may be a case where a wheelchair user M2 is in the car 1 alone and a criminal or a drunk person later enters the car and tries to plunder or act violently.

  When such a criminal act occurs, the in-car use situation monitoring means 7 is based on a detection signal (image data) from the in-car load situation detection means 5 (camera 4 with a wide-angle lens), and passengers in the car 1 Is determined to be abnormal, and a behavior abnormality signal is output to the elevator operation control means 8. Then, the elevator operation control means 8 receives this behavior abnormality signal and issues an abnormality notification signal. When the vehicle is running, the elevator 1 immediately stops the car 1 at the nearest floor, or when it is waiting for door opening. Does not leave the car 1.

  Since this abnormality notification signal is also sent to a management room (not shown), an administrator stationed in the management room can immediately rush to the car 1. Further, the monitoring information from the in-car usage status monitoring unit 7 and the image data from the wide-angle lens-equipped camera 4 are stored in the monitoring information storage unit 9. This stored data can be effectively used later as investigation materials or evidence materials for solving crime cases.

  Further, the elevator system according to the present embodiment can effectively cope not only with the occurrence of criminal acts as described above but also when the passenger feels bad. For example, if passenger M1 feels bad and falls to the floor, or if wheelchair user M2 feels bad and has stopped moving for more than a certain time after opening the door, the same as above. The in-car use state monitoring means 7 outputs a behavior abnormality signal to the elevator operation control means 8, and the elevator operation control means 8 receives this and issues an abnormality notification signal.

  In the above specific example of the present embodiment, the case where the “equipment associated with the passenger” is a wheelchair, that is, the case where the wheelchair user M2 gets into the car 1, is described as “equipment associated with the passenger”. Various other types are conceivable. For example, for the passengers who are getting in while pushing a baby carriage or a stroller, those who are getting in with a cane, passengers who are getting in while checking a travel rod, etc., the in-car use state monitoring means 7 is the object of monitoring. Can be accurately identified and monitored.

  Moreover, in the said embodiment, although the example in which the cage internal load condition detection means 5 was comprised by the pressure-sensitive rubber 3 and the camera 4 with a wide angle lens was shown, it is not necessarily limited to these, For example, a piezoelectric film, It is also possible to use a load sensor such as a resistive conductor.
