The system 200 may comprise a system controller 300 that communicates with the first device 290 and responsively controls the elevator car 260 to transport the passenger 270.
Turning to
According to an embodiment the room 280 has a door 310 that is an egress door and the first device 290 is a door lock. The first data may indicate that the door 310 has been engaged by the passenger 270. According to an embodiment the system includes a plurality of devices including the first device 290 and a second device 330 (e.g., a processor-based devices or smart devices). The second device 330 may be a first power controller for the room 280. According to an embodiment the first determination may include the system controller 300 communicating with the first power controller 330 to confirm that power to one or more utilities in the room 280 is in an off state.
According to an embodiment the first data may indicate that the first device 290 is disposed on the first level 240. From this the system controller 300 may determine the passenger 270 requires elevator service at the first lobby 250.
According to an embodiment the building 210 may comprise a distribution of plurality of the power controllers including the first power controller 330. The first data may provide a room identifier whereby the system controller 300 determines that the first power controller 330 controls power for the room 280.
According to an embodiment a third device 340 may be in the room 280. The third device 340 may be a card controller in operational communication with the first power controller 330. When the card controller 340 determines a card 350 is removed from the card controller 340, the first power controller 330 may set power to the one or more utilities in the room 280 to the off state. According to an embodiment the one or more utilities includes an air conditioning unit.
According to an embodiment when the system controller 300 renders the second determination, if the elevator car 260 is at the second lobby, the first instructions include the elevator car 260 traveling to the first lobby 250 and idling at the first lobby 250 until engages by the passenger.
According to an embodiment the plurality of devices communicate with the system controller 300 over a wireless network. The wireless network 360 may be a personal area network (PAN), for example, Bluetooth, accessible through one or more PAN beacons 370.
According to the above embodiments a system is disclosed which may continuously monitor door states available in a building/hotel from a controller which may be a lock management system (LMS). Whenever a door lock state is active/locked and the guest (passenger) is not in the room (which may be confirmed by checking a state of an air conditioner power supply inside the room), the system may obtain corresponding level information of the room from the LMS. The system may then instruct an elevator to provide service on the same level as the room so as to provide service to the passenger. For example a guest is allocated a room on a level in a hotel. Within the room, when the guest (passenger) removes the key card from the key card holder, the power supply controller turns power off in the room. When the door is locked as the person leaves the room, the system may read both the data from the lock management system and the energy management system to determine that guest (passenger) has left the room. Then the system may send an elevator to the level of the guest. Before the guest (passenger) arrives near the elevator, the assigned elevator may arrive to provide elevator service.
