FIG. 1A illustrates an elevator system 100 according to an aspect. The elevator system 100 comprises an elevator shaft 124 in which an elevator car 110 moves to serve different floors. Although FIG. 1A illustrates five floors 114, 116, 118, 120, 122, it is evident that there may be any number of floors. Similarly, although FIG. 1A illustrates only one elevator shaft 124, there may be more than one elevator shaft in the elevator system.

The elevator car 110 includes at least one elevator car mounted wireless device 106. The term "wireless device" used herein refers to a device that is able to receive or receive and transmit wireless signals, for example, from a controller of the elevator system. In one embodiment, the elevator car mounted wireless device 106 comprises a car operating panel (COP) . It is evident that the elevator car mounted wireless device 106 may refer to any device in the elevator car 110 configured with wireless transmission/reception capabilities. A microphone 108 is also connected to the elevator car mounted wireless device 106. In another example, the microphone 108 may also be part of the elevator car mounted wireless device 106.

Each floor 114, 116, 118, 120, 122, includes at least one wireless device 102A-102E, 104A-104E. FIG. 1A illustrates an example in which a first wireless device 102A-102E may be a landing call station (LCS) and a second wireless device 104A-104E may be a hall lantern indicator (HLI) . In other examples, a display or displays or any other appropriate wireless device needed at a floor may be arranged at all or only in specific floors. When performing a configuration of the wireless devices 102A-102E, 104A-104E, an elevator control apparatus controlling the elevator system may first cause the elevator car 110 to perform an initial commissioning to identify the floors 114, 116, 118, 120, 122. The commissioning may be performed, for example, by performing an end-to-end travel with the elevator car 110 in the elevator shaft 124.

The configuration of the wireless devices 102A-102E, 104A-104E may then comprise a configuration sequence during which the elevator car 110 stops at each floor 114, 116, 118, 120, 122 and the elevator doors and the landing doors 112 are opened. FIG. 1A illustrates a situation in which the elevator car 110 has stopped at the first floor 114.

The elevator car mounted wireless device 106 is caused to initiate an audio handshake with at least one wireless device one by one at each landing floor 114, 116, 118, 120, 122. In one embodiment, the audio handshake is initiated with the wireless devices 102A, 104A one by one.

In an embodiment, the wireless devices 102A, 104A start transmitting audio signals as soon as they identify an initiation signal from the elevator car mounted wireless device 106. The initiation signal may be a wireless or audible initiation signal. In another embodiment, during the configuration of the wireless devices 102A-102E, 104A-104E, they are configured to operate in a configuration mode and they transmit audio signals without first receiving an initiation signal from the elevator car mounted wireless device 106. The configuration mode may be activated remotely so that it is activated in all wireless devices 102A- 102E, 104A-104E substantially simultaneously. In another embodiment, the configuration mode may be activated locally with the initiation signal from the elevator car mounted device 106 separately at each floor. In response to initiating the audio handshake with the wireless device 102A, the elevator car mounted wireless device 106 receives with the microphone 108 during the audio handshake information identifying the wireless device 102A. For example, the wireless device 102A may transmit audio signals (audible or non-audible by humans) to be captured by the microphone 108, where the audio signals comprise a unique identifier of the wireless device 102A. The unique identifier is, for example, a serial number or other identifier uniquely identifying the wireless device 102A among all the wireless devices 102A-102E, 104A-104E.

As the elevator car mounted wireless device 106 already possesses the floor information, it is able to assign the wireless device 102A to a correct floor. Therefore, the elevator car mounted wireless device 106 transmits configuration information to the wireless device 102A, the configuration information comprising the assigned floor information. A similar audio handshake process is repeated with the elevator car mounted wireless device 106 separately with each detected wireless device. In one embodiment, the elevator car mounted wireless device 106 is configured to perform the audio handshake only with wireless devices from which a minimum sound level is received. As an example, a minimum threshold may be applied. The minimum threshold may be set so that signal levels from wireless devices possibly transmitting audio signals in floors other that the floor at which the elevator car 110 is currently located, fall below the minimum threshold. This enables a solution in which the elevator car mounted wireless device 106 performs the audio handshake only with wireless devices in direct vicinity and omits other devices.

In one embodiment, the configuration of the wireless devices 102A-102E, 104A-104E is performed during the initial commissioning when identifying the floors 114, 116, 118, 120, 122. The wireless devices 102A-102E, 104A-104E may be configured to start transmitting audio signals when a configuration or an initial commissioning phase starts. When the elevator car 110 travels in the elevator shaft 124, the elevator car mounted wireless device 106 may simultaneously determine local maxima of signals sent by the wireless devices 102A-102E, 104A-104E. As an example, when the elevator car 110 is at a location or close to it where it normally stops at a specific floor, for example the floor 114, it receives signals from wireless devices 102A, 104A with a stronger signal level than for signals from wireless devices located at other floors 116, 118, 120, 122. Therefore, the signals reach the local maxima in locations where the elevator car 110 normally stops at the floor or close to them. As there are multiple floors, there are multiple local maximum points for the signals received from the wireless devices 102A-102E, 104A-104E. Therefore, in a combined solution, the configuration of the wireless devices 102A-102E, 104A-104E is performed during the initial commissioning when identifying the floors 114, 116, 118, 120, 122. During the configuration, the elevator car 110 may have to perform some position adjustments in the elevator shaft 124 after it has determined a local maximum so that it is located at the local maximum point before initiating the audio handshake procedure. Further, elevator car 110 may not even have to open its doors if the signals from the wireless devices 102A-102E, 104A-104E are identifiable and strong enough. If the doors need not be opened, the configuration process is faster.

In another embodiment, the elevator car mounted wireless device 106 is first configured to perform the initial commissioning that includes also the determination of the local maxima. Then, subsequently the elevator car mounted wireless device 106 is configured to initiate the audio handshake at each local maximum during a subsequent end-to-end travel of the elevator car 110 in the elevator shaft 124. Before initiating the audio handshake, the elevator car 110 may or may not be configured to open its doors.

FIG. IB illustrates an elevator system 130 according to another aspect. The difference between the aspects illustrated in FIGS. 1A and IB is that in FIG. IB the elevator car 110 is able to open its doors towards two different sides 126, 128. In the example illustrated in FIG. IB, the elevator car 110 has opened its doors 132 towards the side 128 at the floor 116. The discussion already presented above for FIG. 1A applies also for FIG. IB with the exception that it may not be reasonable to initiate the audio handshake process while keeping the doors of the elevator car 110 closed as there are now wireless device 102A-102J, 104A-104J on both sides 126, 128 of the elevator car 110. Therefore, in the example illustrated in FIG. IB, the elevator car 110 initiates the audio handshake separately for both sides 126, 128 and opens only doors at one side at a time. FIG. 1C illustrates an elevator system 140 according to another aspect. The elevator system comprises an elevator shaft 124 in which an elevator car 110 moves to serve different floors. Although FIG. 1C illustrates five floors 114, 116, 118, 120, 122, it is evident that there may be any number of floors. Similarly, although FIG. 1C illustrates only one elevator shaft 124, there may be more than one elevator shaft in the elevator system.

Each floor 114, 116, 118, 120, 122, includes at least one wireless device 102A-102E, 104A-104E. FIG. 1C illustrates an example that a first wireless device 102A-102E may be a landing call station (LCS) and a second wireless device 104A-104E may be a hall lantern indicator (HLI) . In other examples, a display or displays or any other appropriate wireless device needed at a floor may be arranged at all or certain floors .

In this aspect, the configuration of the wireless devices 102A-102E, 104A-104E with a portable wireless device 142 is carried by a commissioner 144. The portable wireless device 142 also comprises a microphone or an external microphone may be connected to the portable wireless device 142. As an example, the portable wireless device 142 may be a mobile phone.

In order to configure the wireless devices 102A, 104A, the portable wireless device 142 initiates an audio handshake with the wireless devices 102A, 104A one by one. Prior to initiating the audio handshake, the commissioner 144 may have selected an area and/or floor that he is about to configure with the portable wireless device 142. In response to initiating the audio handshake, the portable wireless device 142 receives with the microphone from a wireless device 102A, 104A information identifying the wireless device 102A, 104A. For example, the wireless device 102A may transmit audio signals (audible or non-audible by humans) to be captured by the microphone, where the audio signals comprise a unique identifier of the wireless device 102A. The unique identifier is, for example, a serial number or other identifier uniquely identifying the wireless device 102A among all the wireless devices 102A-102E, 104A-104E. In response to receiving the information identifying the wireless device 102A, the portable wireless device 142 is configured to transmit configuration information to the wireless device 102A, the configuration information assigning the wireless device to a specific floor and/or area as selected earlier by the commissioner 144.

In an embodiment, the wireless devices 102A, 104A start transmitting audio signals as soon as they identify an initiation signal from the portable wireless device 142. In another embodiment, during the configuration of the wireless devices 102A-102E, 104A- 104E, they are configured to operate in a configuration mode and they transmit audio signals without first receiving an initiation signal from the portable wireless device 142.

In an embodiment, the portable wireless device 142 is configured to perform the audio handshake only with wireless devices from which a minimum sound level is received. This avoids misconfiguring the wireless device to an incorrect floor and/or area and enables a solution in which the portable wireless device 106 performs the audio handshake only with wireless devices in direct vicinity and omits other devices. FIG. 2 illustrates elements in an elevator system according to an aspect. The elevator system comprises an elevator controller 200 connected to at least one wireless router 202.

The at least one wireless device 102A-102J, 104A-104J comprises, for example, the wireless devices located at the landing floors. The device 106, 142 may be a portable wireless device 142 carried by a commissioner or an elevator car mounted wireless device 106.

The at least one wireless device 318 comprises, for example, the elevator car mounted wireless device 106 and wireless devices 102A-102J, 104A-104J at the landing floors. The controller 310 may be used to control elevator car 110 and the elevator car mounted wireless device 106 and the wireless devices 102A-102J. The illustrated components are not required or all- inclusive, as any components can deleted and other components can be added.
