In accordance with one or more embodiments, the one or more sensors 245, 246 are stain gauges arranged under a floor of the elevator cars 231, 232 that detect a total weight of the passengers in relation to a weight threshold (corresponding to the total occupancy limit) in the elevator cars 231, 232. In accordance with one or more embodiments, the one or more sensors 245, 246 are cameras arranged in a ceiling of the elevator cars 231, 232 that detect a total number of the passengers through image recognition in the elevator cars 231, 232 in relation to the total occupancy limit.

The network 250 can be a distributed cloud computing environment (e.g., a cloud distribution system) where tasks are performed by remote processing devices that are linked through a communications within the network 250. The network 250 can comprise hardware and/or software that are similar to the computing device 220 described herein. In the network 250, program modules may be located in both local and remote computer system storage media including memory storage devices. Operations of the system 200 will now be described with respect to FIGS. 3-4.

FIG. 3 depicts detection operations with respect to a process flow 300 of the detection system 200 in accordance with one or more embodiments. More particularly, the process flow 300 is a dynamic car assignment process where blocks 310 and 320 relate to a Scenario X of the detection system 200, blocks 330, 340, and 350 relates to a Scenario Y of the detection system 200, and block 360 relates to a Scenario Z of the detection system 200.

At block 310, the elevator subsystem 240 receives a hall call from the lobby 203. The hall call is initiated by the user 201 waiting in the lobby 203 for one of the elevator cars 231, 232, which are not located at a same floor as the lobby 203 at the time of the hall call. At block 320, the elevator subsystem 240 assigns the elevator car 231 (e.g., a first elevator car) to pick up the user 201 in response to the hall call. That is, because for each of the elevator cars 231, 232 a total occupancy is four passengers and because the elevator car 231 is unoccupied as shown in Scenario X, the elevator subsystem 240 assigns the elevator car 231.

In an example, prior to assigning the elevator car 231, the elevator subsystem 240 utilizes the sensor 245 to detect an occupancy of the elevator car 231 and determines whether the occupancy is less than the total occupancy limit for the elevator car 231. If the occupancy is less than the total occupancy limit for the elevator car 231, then the elevator subsystem 240 assigns the elevator car 231. If the occupancy is equal to the total occupancy limit for the elevator car 231, then the elevator subsystem 240 transitions the elevator car 232 and repeats the analysis.

At block 330, the elevator subsystem 240 detects that the elevator car 231 (e.g., the assigned first elevator car) is fully occupied. The elevator subsystem 240 detects that the elevator car 231 is fully occupied prior to the elevator car 231 arriving at the lobby 203. For example, the elevator subsystem 240 detects each time one or more other passengers (e.g., one of the users B, C, D, E) enter the elevator car 231 prior to the elevator car 231 arriving at the lobby 203. And, because the elevator car 231 has a total occupancy limit of four passengers before arrival at the lobby 203, the elevator subsystem 240 identifies that the elevator car 231 is fully occupied as shown in Scenario Y.

At block 340, the elevator subsystem 240 dynamically assigns the elevator car 232 (e.g., a second elevator car) to pick up the user 201 in response to the hall call. In an example, prior to assigning the elevator car 232, the elevator subsystem 240 utilizes the sensor 246 to detect an occupancy of the elevator car 232 and determines whether the occupancy is less than the total occupancy limit for the elevator car 232. If the occupancy is less than the total occupancy limit for the elevator car 232, then the elevator subsystem 240 assigns the elevator car 232. At block 350, the elevator subsystem 240 cancels the assignment of the elevator car 231.

At block 360, the elevator subsystem 240 detects that the user 201 boarded the elevator car 232 (e.g., the assigned second elevator car). As shown in Scenario Z, the user 201 has boarded the elevator car 232.

In view of the above, the technical effects and benefits include improving an ability of the elevator subsystem 240 to manage hall calls. In this regard, the detection system 200 can automatically re-routes and re-assigns elevator cars based on occupancy without wasting time of the user 201 and the users B, C, D, E and wasting operation cycles of the elevator subsystem 240 itself.

FIG. 4 depicts a process flows 401, 402 of components of a detection system in accordance with one or more embodiments. As shown in FIG. 4, operations of the mobile device 220 according to process flow 401 are executed with respect to operations of the elevator subsystem 240 according to process flow 402.

At block 405, a call is initiated from the mobile device 220 including a floor location. In accordance with one or more embodiments, the call can be a mobile call generated by the software 223 in accordance with a user input. The floor location can be pre-determined by the mobile device 220 based on a global positioning system or other location technology.

At block 410, the elevator subsystem 240 receives the call from the mobile device 220. The call can be received via the network 250, such as through cellular technologies. At block 420, the elevator subsystem 240 assigns a first elevator car (e.g., the elevator car 231) to the mobile device 220 in response to the call. That assignment is further communicated to the mobile device 220 by the elevator subsystem 240. At block 425, the mobile device 220 display a prompt indicating the assigned first elevator car.

At block 430, the elevator subsystem 240 detects that the assigned first elevator car is fully occupied before arrival at the floor location. At block 440, the elevator subsystem 240 assigns dynamically assigns a second elevator car (e.g., the elevator car 232) to the mobile device 202 in response to detecting a fully occupied first car. At block 445, the mobile device 220 updates the prompt to the assigned second elevator car.

At block 450, the elevator subsystem 240 cancels assignment of first elevator. At block 460, the elevator subsystem 240 detects that the mobile device 220 boarded the assigned second elevator car. The boarding by the mobile device 220 can be detected by the elevator subsystem 240 based on the sensor 245 communicating with the mobile device and/or a global positioning system or other location technology.
