DETAILED DESCRIPTION

FIG. 1 is a perspective view of an elevator system 101 including an elevator car 103, a counterweight 105, a tension member 107, a guide rail 109, a machine 111, a position reference system 113, and a system controller 115. The elevator car 103 and counterweight 105 are connected to each other by the tension member 107. The tension member 107 may include or be configured as, for example, ropes, steel cables, and/or coated-steel belts. The counterweight 105 is configured to balance a load of the elevator car 103 and is configured to facilitate movement of the elevator car 103 concurrently and in an opposite direction with respect to the counterweight 105 within an elevator shaft 117 and along the guide rail 109.

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 system 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 system controller 115 may provide drive signals to the machine 111 to control the acceleration, deceleration, leveling, stopping, etc. of the elevator car 103. The system 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 system 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 system controller 115 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. FIG. 1 is merely a non-limiting example presented for illustrative and explanatory purposes.

In other embodiments, the system comprises a conveyance system that moves passengers between floors and/or along a single floor. Such conveyance systems may include escalators systems, moving walkways, metro systems (e.g., subway systems), train systems, conveyer systems, production lines, people movers, etc. Accordingly, embodiments described herein are not limited to elevator systems, such as that shown in FIG. 1. In one example, embodiments disclosed herein may be applicable conveyance systems such as an elevator system 101 and a conveyance system component such as an elevator car 103 of the elevator system 101. In another example, embodiments disclosed herein may be applicable conveyance systems such as an escalator system and a conveyance system component such as a moving stair of the escalator system.

FIG. 2 is a view of a data network 200 including one or more mobile wireless access points 210, according to an embodiment of the present disclosure. The mobile wireless access point 210 may be a radio communication device capable of communicating via short-range wireless protocols 203 (e.g., BLE, Zwave, BT, Wi-Fi, ZigBee, and IEEE 802.15.4 Sub-GHz). The mobile wireless access points 210 may also be capable of communicating via long-range wireless protocols 204 internally within a building but may be in a location within the building such that communication via long-range wireless protocols 204 to a device located outside of the building may be difficult. As shown in FIG. 2, the mobile wireless access points 210 are each located on an elevator car 103 and are configured to move up and down throughout a respective hoistway 117 with the elevator car 103. Alternatively, the wireless access point 210 can be located on another part of the elevator system 101 that moves through the hoistway 117, such as, for example, the counterweight 105. The mobile wireless access points 210 are configured to communicate via short-range wireless protocols 203 with communication nodes 280, other mobile wireless access points 210, and a local gateway device 240. Additionally the data network 200 may include one or more stationary information buffers 270 that could be assist with moving data 202 from lower landings 125 to the higher landings 125 or in horizontal motion (i.e., act like a temporary buffer in systems that don't have continuous communication). The mobile wireless access points 210 are configured to transfer data 202 between the communication nodes 280 and the local gateway device 240, then the local gateway device 240 is configured to transmit the data 202 to a remote system 280 through a network 250 via long-range wireless protocol 204. The local gateway device 240 may also receive data 202 from the remote system 280 through the network 250 via long-range protocol 204 and then the data 202 may be distributed to communication nodes 280 by the mobile wireless access points 210. The network 250 may be a computing network, such as, for example, a cloud computing network, cellular network, satellite network, or any other computing network known to one of skill in the art. The network 250 may also be a computing network hardwired from the local gateway device 240 to the remote system 280.

The communication nodes 280 may be low power devices with a limited wireless range 282. The communication nodes 280 not be able to communicate wirelessly through building landings 125 due to the limited wireless range of the communication nodes 280. The communication nodes 280 may be dedicated devices specifically for transferring data 202 to the mobile wireless access points 210 or may be dual devices that serve other functions in addition to transferring data 200 to the mobile wireless access points 210, such as, for example, a thermostat, a smoke sensor, a CO detector, a CO₂ detector. The communication node 280 is configured to transmit data 202 to a mobile wireless access point 210 via short-range wireless protocol 203 when the mobile wireless access point 210 is located within the wireless range 282 of the communication node 280. Short-range wireless protocols 203 may include but are not limited to Bluetooth, Wi-Fi, HaLow (801.11ah), zWave, Zigbee, RFID, or Wireless M-Bus. The mobile wireless access point 210 may only be located within the wireless range 282 of the communication node 280 if the mobile wireless access point 210 is located on the same landing 125 of the communication node 280 (e.g., if the communication node 280 cannot transmit through landings 125 of the building.

The mobile wireless access points 210 may then save the data 202 within a memory 216 of the of the mobile wireless access points 210 and then transmit the data 202 to the local gateway device 240 when the mobile wireless access point 210 is within a wireless range of the local gateway device 240. The mobile wireless access point 210 may also transmit the data 202 to another wireless access point 210 if it would be more efficient for the other wireless access point 210 to carry the data 202 to the local gateway device 240. For example, if a wireless access point 210 on a first elevator car 103a was traveling downward and passing a wireless access point 210 on a second elevator car 103b travelling upward to the local gateway device 240 then the wireless access point 210 on the first elevator car 103a may transfer data 202 to the wireless access point 210 on the second elevator car 103b, so that the wireless access point 210 on the second elevator car 103b could convey the data 202 up to the local gateway device 240.

The mobile wireless access point 210 may only be located within the wireless range of the local gateway device 240 if the mobile wireless access point 210 is located on the same landing 125 of the local gateway device 240 (e.g., if the mobile wireless access point 210 cannot transmit through landings 125 of the building). For example, if the mobile wireless access point 210 cannot transmit through landings 125 of the building and the local gateway device 240 is located on a top landing 125a then the mobile wireless access point 210 can only transmit data 202 to the local gateway device 240 when the mobile wireless access point 210 is on the top landing 125a.

In an embodiment, the mobile wireless access point 210 may be a passive rider of the elevator car 103 not having control of the movement of the elevator car 103, thus the data transfer rate may be a subservient to and dependent upon the schedule of the elevator car 103. In another embodiment, the mobile wireless access point 210 may be an active rider of the elevator car 130 configured to control the schedule and operation of the elevator car 103 to facilitate the transfer of data 202 between communication nodes and the local gateway device 240, and then onto the remote system 290. It is import to note that the process may also operate in reverse with data 202 being transferred from the remote system 290 to the local gateway device 240, to the mobile wireless access points 210, and onto the communication nodes 280, as illustrated by method 500 in FIG. 5.

The remote system 290 may be a computing device, such as, for example, a desktop computer, server, cloud computer, etc. The remote system 290 may also be a mobile computing device that is typically carried by a person, such as, for example a smartphone, PDA, smartwatch, tablet, laptop, etc. The remote system 290 may also be two or more separate devices that are synced together, such as, for example, a cellular phone and a desktop computer synced over an internet connection.

As mentioned above, short-range wireless protocols 203 facilitate communication: between communication nodes 280 and mobile wireless access points 210; between a mobile wireless access point 210 and another mobile wireless access point 210; and between the mobile wireless access points 210 and the local gateway device 240. Short-range wireless protocols 203 may include but are not limited to Bluetooth, Wi-Fi, HaLow (801.11ah), zWave, Zigbee, RFID, or Wireless M-Bus.

As mentioned above, long-range wireless protocols 204 facilitate communication: between the local gateway device 240 and the network 250; between the network 250 and the remote system 290; and between the local gateway device 240 and the remote system 290. In an embodiment, the local gateway device 240 may communicate directly with the remote system 290 via long-range wireless protocol 204. Long-range wireless protocols 204 may include but are not limited to cellular, satellite, GSM, CDMA, LTE (NB-IoT, CAT M1), LoRa, Ingenu or SigFox.

FIG. 3 illustrates a block diagram of the mobile wireless access point 210. It should be appreciated that, although particular systems are separately defined in the schematic block diagram of FIG. 3, each or any of the systems may be otherwise combined or separated via hardware and/or software. As shown in FIG. 3, the mobile wireless access point 210 may include a controller 212, a short-range communication module 220 in communication with the controller 212, and a power source 222 electrically connected to the controller 212.

The controller 212 of the mobile wireless access point 210 includes a processor 214 and an associated memory 216 comprising computer-executable instructions that, when executed by the processor 214, cause the processor 214 to perform various operations, such as, for example, processing the data 202. The processor 214 may be but is not limited to a single-processor or multi-processor system of any of a wide array of possible architectures, including field programmable gate array (FPGA), central processing unit (CPU), application specific integrated circuits (ASIC), digital signal processor (DSP) or graphics processing unit (GPU) hardware arranged homogenously or heterogeneously. The memory 216 may be a storage device, such as, for example, a random access memory (RAM), read only memory (ROM), or other electronic, optical, magnetic or any other computer readable medium.

The power source 222 of the mobile wireless access point 210 is configured to store and supply electrical power to the mobile wireless access point 210. The power source 222 may include an energy storage system, such as, for example, a battery system, capacitor, or other energy storage system known to one of skill in the art. The power source 222 may also generate electrical power for the mobile wireless access point 210.

The mobile wireless access point 210 includes a short-range communication module 220 located within the mobile wireless access point 210. The short-range communication module 220 is configured to allow the controller 212 of the mobile wireless access point 210 to communicate with the communication nodes 280, other mobile wireless access points 210, and the local gateway device 240 through short-range wireless protocols 203. The short-range communication module 220 may consist of one or more wireless transceivers capable of transmitting/receiving data 202 to/from the local gateway device 240 and the nodes 280. In an embodiment, the short-wave wireless protocol 203 for communication between the mobile wireless access point 210 and the communication nodes 280 may be different than the short-wave wireless protocol 203 for communication between the mobile wireless access point 210 and the local gateway device 240, and thus may require two different wireless transceivers within the short-range communication module 220.
