no. 1 Embodiment approach

[0072] The elevator monitoring device 1 according to the first embodiment will be described. Figure 7 An installation example of the imaging unit 2 according to the first embodiment installed on an elevator and an example of an image acquired by the imaging unit 2 are shown. Figure 7 (a) is a view of the interior of the car viewed from the outside of the elevator, and is an example in which the imaging unit 2 for photographing the inside of the elevator car is installed on the right rear upper portion facing the inside of the elevator car. Then, Figure 7 (b) and Figure 7 (c) is an example of an image obtained when the viewing angle of the imaging unit 2 faces the entrance and exit of the car. The person 43 shown in the checkered pattern area is an example of a person who has already boarded. The person 41 shown in the grid pattern area is an example of a person who is about to board. In addition, the infant 42 shown in the checkered pattern area is an example in which ...

no. 2 Embodiment approach

[0147] Next, the elevator monitoring device 20 according to the second embodiment will be described. Image 6 This is an example of the configuration of the elevator monitoring device 20 of the second embodiment. The second embodiment is an example in which the computing unit 4 of the first embodiment is realized by the processor board 21 .

[0148] The processor board 21 is composed of a processor 22 , an image interface (image IF) 23 , a sensor interface (sensor IF) 24 , a memory 25 , and a communication interface 26 , and these structures are connected by a signal line 29 . As for the power cord, it is assumed that it is properly connected, and description thereof is omitted. The image interface 23 converts the image captured by the imaging unit 2 into digital values ​​so that the processor 22 can process it. The sensor interface 24 converts the load value measured by the load sensor 3 into a value that the processor 22 can process. The communication interface 26 convert...

no. 3 Embodiment approach

[0152] Next, the elevator monitoring device 60 according to the third embodiment will be described. Figure 11 It is an example of a configuration diagram of the elevator monitoring device 60 according to the third embodiment. The elevator monitoring device 60 according to the third embodiment includes, for example, the imaging unit 2 , the load sensor 3 , the calculation unit 61 , the output unit 63 , the communication line 64 , and the notification unit 65 . In addition, the elevator monitoring apparatus 60 may have the elevator control part 71 which controls an elevator.

[0153] In addition to the functions of the elevator monitoring device 1 according to the first embodiment, the elevator monitoring device 60 has a function of judging whether an unmeasured person such as a light infant or small animal who is too light for the load sensor 3 to measure enters alone. This erroneous entry of an unmeasurable person corresponds to a special case in the human presence determina...

Abstract

The invention provides an elevator monitoring device and a monitoring method, which, when a combined loading sensor and an image sensor judge whether an elevator car is occupied or unoccupied, can inhibit missing reports on an unmeasurable body such as an extremely light infant or a small animal, and reduce the load of image processing performed by the image sensor. An image of a photographing part is processed and thus a new passenger who enters the elevator car is detected, whether the new passenger is a specified light-weight passenger, i.e., an unmeasurable body, is judged according to a change of a loading value of the loading sensor when the new passenger takes the elevator, in the circumstance that the new passenger is judged to be an unmeasurable body, till the unmeasurable body exits from the elevator car, image tracking is performed to judge whether an unmeasurable body mixes into the elevator car, and in the circumstance that the unmeasurable body is judged to mix into the elevator car, the elevator car is judged to be ??occupied??.

Description

technical field [0001] The present invention relates to an elevator monitoring device and a monitoring method. Background technique [0002] The car of the elevator is provided with a load detection device (hereinafter referred to as a load sensor) for detecting excess loading. In addition, in recent years, cars equipped with security cameras have also been popularized. [0003] In addition, Patent Document 1 describes a technology based on one or both of a load detection device installed on a car moving up and down in an elevator hoistway, and a camera for taking pictures of safety precautions in the car. Combine the obtained information to judge whether there are passengers in the car. [0004] In addition, Patent Document 2 describes a technology that includes an image acquisition unit that acquires an image inside an elevator car, and a weight measurement unit that measures a passenger's weight, based on the weight of a passenger measured by the weight measurement unit...
