In addition to one or more of the above disclosed features or as an alternate the controller is configured for: rendering a third determination that the first video data includes a number of shapes at the first lobby, rendering a fourth determination that the number of detected shapes corresponds with a count of people at the first lobby, and rendering a fifth determination that the count of people corresponds with the plurality of passengers.
In addition to one or more of the above disclosed features or as an alternate the controller is configured for: executing a fourth communication instructing the panel to display the count of people at the first lobby that are receiving elevator service with the first elevator car.
In addition to one or more of the above disclosed features or as an alternate the controller is configured for: rendering a sixth determination that a first capacity for the first elevator car is exceeded by the count of people at the first lobby, and executing a fifth communication to instruct a plurality of elevator cars, including the first elevator car, to effect elevator service at the first lobby.
In addition to one or more of the above disclosed features or as an alternate the controller is configured for: executing a sixth communication of instructing the first panel to display information indicating that the plurality of elevator cars is assigned to effect elevator service at the first lobby.
In addition to one or more of the above disclosed features or as an alternate, when the first capacity for the first elevator car is exceeded by the number of detected people at the first lobby, the controller is configured for: executing a seventh communication instructing the first panel to display information indicating the time of arrival for the plurality of elevator cars.
In addition to one or more of the above disclosed features or as an alternate the controller is configured for: executing an eighth communication of instructing the panel to display the number of people detected at the first lobby that are receiving elevator service with each of the plurality of elevator cars.
In addition to one or more of the above disclosed features or as an alternate the controller communicates with the elevator cars and the panel over a CAN network.
The present disclosure is illustrated by way of example and not limited in the accompanying figures in which like reference numerals indicate similar elements.
The tension member 107 engages the machine 111, which is part of an overhead structure of the elevator system 101. The machine 111 is configured to control movement between the elevator car 103 and the counterweight 105. The position reference system 113 may be mounted on a fixed part at the top of the elevator shaft 117, such as on a support or guide rail, and may be configured to provide position signals related to a position of the elevator car 103 within the elevator shaft 117. In other embodiments, the position reference system 113 may be directly mounted to a moving component of the machine 111, or may be located in other positions and/or configurations as known in the art. The position reference system 113 can be any device or mechanism for monitoring a position of an elevator car and/or counter weight, as known in the art. For example, without limitation, the position reference system 113 can be an encoder, sensor, or other system and can include velocity sensing, absolute position sensing, etc., as will be appreciated by those of skill in the art.
The controller 115 is located, as shown, in a controller room 121 of the elevator shaft 117 and is configured to control the operation of the elevator system 101, and particularly the elevator car 103. For example, the controller 115 may provide drive signals to the machine 111 to control the acceleration, deceleration, leveling, stopping, etc. of the elevator car 103. The controller 115 may also be configured to receive position signals from the position reference system 113 or any other desired position reference device. When moving up or down within the elevator shaft 117 along guide rail 109, the elevator car 103 may stop at one or more landings 125 as controlled by the controller 115. Although shown in a controller room 121, those of skill in the art will appreciate that the controller 115 can be located and/or configured in other locations or positions within the elevator system 101. In one embodiment, the controller may be located remotely or in the cloud.
The machine 111 may include a motor or similar driving mechanism. In accordance with embodiments of the disclosure, the machine 111 is configured to include an electrically driven motor. The power supply for the motor may be any power source, including a power grid, which, in combination with other components, is supplied to the motor. The machine 111 may include a traction sheave that imparts force to tension member 107 to move the elevator car 103 within elevator shaft 117.
Although shown and described with a roping system including tension member 107, elevator systems that employ other methods and mechanisms of moving an elevator car within an elevator shaft may employ embodiments of the present disclosure. For example, embodiments may be employed in ropeless elevator systems using a linear motor to impart motion to an elevator car. Embodiments may also be employed in ropeless elevator systems using a hydraulic lift to impart motion to an elevator car.

The controller 210 may communicate with the first elevator car 225 over a controller area network (CAN) 300. In addition the controller 210 may communicate with a mobile device 310 for the first passenger 250 as may be needed, for example to communicate elevator assignment information, over a personal area network (PAN) 320 over a network beacon 330. The controller may communicate with the panel 260 over a local area network (LAN) 340. The CAN 300, PAN 320 and LAN 340 networks are examples of suitable networks; it is understood that other network topologies may be used in the elevator system 200.
In the above disclosed embodiments when an elevator call is executed at an elevator lobby, the system detects a passenger count using video data. The video data, for example, is obtained using a three dimensional (3D) stereoscope camera disposed in the lobby. Obtain data may be is processed with machine learning (ML) analytics to obtain an approximate people count. Based on a people count and an elevator capacity, the system may predict a number of elevators needed to effect elevator service. The system instruct a display in the lobby to identify a passenger count, a number of elevator cars dispatched to effect elevator service at the first lobby, and a waiting time for elevator service. The disclosed embodiments may help to reduce wait time for elevator service.
As used herein an elevator controller and/or elevator group controller (EGC) may be a microprocessor based controller that controls many aspects of the elevator operation. A series of sensors, controllers, sequences of operation and real-time calculations or algorithms that balance passenger demand and car availability. Elevator sensors may provide data on car positions, car moving direction, loads, door status, hall calls, car calls, pending up hall and down hall calls, number of runs per car, alarms, etc. The controllers may also have a function enabling the testing the systems without shutdown of the elevator. From collected data, a management system consisting of a workstation and software applications that may create metrics for a group or particular car such as total number of door openings, number of runs per car or call, up and down hall calls, etc. Some performance indicators may be related to passenger wait times and/or elevator car travel times. These metrics may indicate inadequate controls, misconfiguration or even equipment malfunction. Elevator monitoring may be provided as Software as a Service (SaaS). The monitoring may identify malfunctions or abnormal operating parameters and automatically dispatch a technician and/or provide alerts to relevant persons such as building owners. Some systems may provide customer dashboards accessible via a web browser and/or provide owners with information such as performance summaries and maintenance histories. As indicated, the elevator controller may communicate with the one or more elevators over a Controller Area Network (CAN) bus. A CAN is a vehicle bus standard that allow microcontrollers and devices to communicate with each other in applications without a host computer. CAN is a message-based protocol released by the International Organization for Standards (ISO). Downstream communications from the elevator system controller may be over a LAN.
