Description

This disclosure relates to sensors for monitoring elevator landings or inside elevator cars. Traditionally, sensors such as cameras have been installed in elevator landings or inside the elevator car to monitor the conditions of the landing. Information obtained from sensors installed in elevator landings or inside elevator cars is used in elevator systems, for example, to estimate the number of waiting passengers at each landing (see, for example, Patent Document 1). Japanese Patent Publication No. 2013-173595 The first embodiment shows an example of the landing situation assuming the elevator to be installed is located on the landing. Figure 1A is a schematic diagram showing an example of an elevation view of the elevator assuming it is installed on the landing, and Figure 1B is a schematic diagram showing an example of a plan view of the elevator shown in Figure 1A.The first embodiment shows another example of the landing situation when the elevator to be installed is located on the landing. Figure 2A is a schematic diagram showing an example of an elevation perspective view of the elevator when it is located on the landing, and Figure 2B is a schematic diagram showing an example of a plan view of the elevator shown in Figure 2A.This diagram shows an example of the landing situation in Embodiment 1, assuming that the elevator to be installed is located on the landing. The diagram also shows an example of the landing situation assuming that the cameras, which have been initially installed with two cameras mounted on the side wall of the door, are installed on the landing.This diagram shows an example of the landing situation in Embodiment 1, assuming that the elevator to be installed is located on the landing. The diagram also shows an example of the landing situation assuming that the cameras, which have been initially installed with two cameras mounted on the side wall of the door, are installed on the landing.Figures 5A and 5B are diagrams illustrating an example of the landing situation in Embodiment 1, assuming that the elevator and signage to be installed are set up at the landing.This figure shows an example configuration of an inspection system used by an elevator installation company to obtain initial setup information for performing initial camera setup when installing an elevator at an actual landing, in Embodiment 1.This flowchart illustrates an example of the operation of an inspection system used by an elevator installation company to perform initial camera setup when installing an elevator at an actual landing, in Embodiment 1.Figures 8A and 8B show an example of the hardware configuration of the inspection system according to Embodiment 1.This figure shows an example of a camera configuration in Embodiment 1 that has a function to perform calibration.This flowchart illustrates an example of the operation of a camera in Embodiment 1 that has a function to perform calibration when installed at an actual boarding area.The first embodiment shows an example of the situation inside a cage when the cage to be installed is installed inside a building. Figure 11A is a schematic perspective view showing an example of a cage installed inside a building, and Figure 11B is a schematic top view showing an example of the inside of the cage shown in Figure 11A viewed from above.This diagram illustrates an example of the process by which monitoring information is displayed in an elevator system. The embodiments of this disclosure will be described in detail below with reference to the drawings. Embodiment 1. The sensor according to Embodiment 1 is a landing monitoring sensor that monitors the conditions inside an elevator landing or car. The sensors monitor the presence or absence of users in the elevator landing or inside the elevator car, and if users are present, their attributes. The sensors can acquire attribute information not only for people, but also for wheelchairs, strollers, cardboard boxes, luggage racks, electric bicycles, and electric wheelchairs. The sensor includes a camera, lidar, or radar. In the following Embodiment 1, the sensor is assumed to be a camera as an example. When installing a camera to monitor the situation at or inside an elevator landing or car, the camera must be installed in an appropriate manner so that it can monitor the area it is supposed to monitor (hereinafter referred to as the "monitoring area") without fail. In Embodiment 1, the monitoring area is assumed to be, for example, the area of the landing in front of the elevator car (hereinafter referred to as the "in-car area") or the area inside the elevator car (hereinafter referred to as the "in-car area"). In Embodiment 1, adjusting the camera's configuration so that it is appropriate when installed in an elevator landing or car is referred to as "initial setup." That is, when installing a camera to monitor the situation in an elevator landing or car, it is necessary to install the camera in an initial setup state
