BACKGROUND OF THE INVENTION Collecting information pertaining to a transportation device (such as an elevator, escalator or moving walkway) is desirable for several reasons. For example, collecting audiovisual information concerning occupants of the elevator is particularly useful for security and safety systems. More specifically, being able to collect video footage of the occupants inside the elevator enables security officers to identify occupants who may, for instance, vandalise the passenger area of the elevator. The ability to collect audio information from the occupants of the elevator enables, for example, an emergency call centre operator to communicate with the occupants when the elevator unexpectedly breaks down trapping occupants therein. Other information relating to the elevator that may be desirable to collect includes information pertaining to the status of the elevator. For example, status information would typically allow a maintenance engineer to readily determine the status of the elevator, such as the floor at which the elevator is located or any faults identified with the elevator system.

Additionally, personal information relating to the users of

a transportation device can be particularly useful for security systems and would enable security officers to determine which users are using (or have used) the transportation device at any particular time and/or to store a history of usage for future reference.

BRIEF DESCRIPTION OF THE FIGURES Notwithstanding any other embodiments that may fall within the scope of the present invention, an embodiment of the present invention will now be described, by way of example only, with reference to the accompanying figures in which: figure 1 shows a schematic diagram of a system in accordance with an embodiment of the present invention ; and

figure 2 shows a flow chart of various steps performed by the system of figure 1.

AN EMBODIMENT OF THE PRESENT INVENTION As can be seen in figure 1, a system 1 according to an embodiment of the present invention comprises: a building server 3 ; an elevator interface system 5 ; an elevator client 7 ; security access and user management system 8 ; a communication switch 9 ; and communication links 11.

The elevator client 7 is located on a transportation device in the form of an elevator 13 and is essentially concerned with creating first information related to a person in the elevator 13. The first information comprises video and/or audio information. In order to create the first information, the elevator client 7 comprises a personal computer, a video camera that is connected to the personal computer, and a microphone that is also connected to the personal computer (all of which are not illustrated in figure 1). The video camera and the microphone are typical of those used in security systems and are arranged to capture video and audio from the passenger area of the elevator 13. The video and audio signals from the video camera and microphone are forwarded to the personal computer via a video/audio cable. The personal computer comprises a video/audio capture card that processes the video and audio signals from the video camera and microphone to produce a digital version of the video and audio signals. The personal computer is further arranged to place the digital versions of the video and audio signals into a format that can be transmitted over the communication link lla in a reliable manner. In the present embodiment of the invention the format in which the video and audio signals are transmitted over the communication link lla comprises an Ethernet format. The

communication link lla is an Ethernet cable strung to the travelling cable attached between the elevator 13 and the elevator motor room (not shown in figure 1).

As can be seen in figure 1, the communication link lla is connected between the elevator client 7 and the communication switch 9 (which in the present embodiment of the invention is a multi-port Ethernet switch).

Consequently, the digital versions of the video and audio signals from the video camera and microphone (which accord with the Ethernet format) are received by the communication switch 9. Given that the digital versions of the video and audio signals are transmitted over the communication link lla according to the Ethernet format, the communication switch 9 is arranged to process information on the communication link lla that is in an Ethernet format.

The first information also comprises security related information such as a security access pass identification number and any associated personal information such as user name, user address, photo of the user, a scan of a business card of the person or a scan of driver's licence of the person.

In order to obtain the security related information, the system 1 comprises a security access and user management system 8, which is capable of obtaining the security related information from swipe card access usage records and a corresponding database containing personal information of swipe card users. The security access and user management system 8 is typically located within a dedicated security room in the building (which is not shown in figure 1) and is arranged to obtain information about the usage and users of elevator 13 by, for example, a card swipe mechanism or RFID system.

The security access and user management system 8

comprises a communication interface that is capable of arranging the security related information into a format that accords with an Ethernet format. The communication interface is such that it places the security related information onto the communication link lib, which is in the form of an Ethernet cable that extends between the security access and user management system 8 and the communication switch 9.

System 1 also comprises an elevator interface system 5. The elevator interface system 5 is in the form of a PC-based programmable logic controller (which in the present embodiment of the invention is an ADAM 5000 from Advantech Co. , Limited) that is used for data acquisition and which is connected to an elevator control system which controls the operation of the elevator 13. The elevator control system is typically located in the elevator motor room (which is not shown in figure 1). The elevator interface system 5 is arranged to create second information comprising a status of the elevator 13. More specifically, the second information comprises details including direction, floor position, door status and mode of the elevator.

The elevator interface system 5 comprises a communication interface that is capable of arranging the second information into a format that accords with an Ethernet format. The communication interface is such that it places the second information onto the communication link llc, which is in the form of an Ethernet cable that extends between the elevator interface system 5 and the communication switch 9.

The communication link lie is connected between the elevator interface system 5 and the communication switch 9. Consequently, when the elevator interface system 5 places the second information on the communication link

lie it is received by the communication switch 9.

The elevator client 7, the security access and user management system 8 and the elevator interface system 5 place the first information (audiovisual information and security related information) and second information onto the communication links lla, llb and llc, respectively, in a streaming fashion ; that is, the elevator client 7, the security access and user management system 8 and elevator interface system 5 output the information on a continuos basis.

The communication switch 9 is arranged such that upon receiving information via the communication links lla, llb and llc (that is, the first information and the second information), it re-directs that information onto communication link lld. The communication link lld is in the form of a cable that supports the Ethernet communication standard. The communication switch 9 places information onto the communication link lld in the Ethernet format. The communication link lid is connected to the building server 3 ; consequently, any information placed on the communication link lld by the switch 9 will be received by the building server 3. This means that the first information created by the elevator client 7 and the security access and user management system 8, and the second information created by the elevator interface system 5 will ultimately be received by the building server 3 via the communication link lld.

The building server 3 comprises an obtaining means which is arranged to enable the building server 3 to obtain the first information (audiovisual information and security related information) and the second information (elevator status information). Essentially, the obtaining means is in the form of hardware and/or software that is capable of interacting with the communication link lid in

order to retrieve the first information and the second information, which was initially placed on the link lid by the communication switch 9. The obtaining means is further arranged such that it supports the Ethernet format so that it can decode the information placed onto the link lld by the switch 9.

The building server 3 also comprises an associating means that is arranged to create an association between the first information and the second information retrieved from the communication link lld by the obtaining means. The associating means is also in the form of hardware and/or software. In order to create the association between the first information and the second information, the associating means essentially marks the first information and the second information with a time and/or date stamp. The first information and the second information are marked with the time and/or date stamp shortly after the information is obtained by the obtaining means. The building server 3 comprises an internal clock (which is periodically synchronised with a standard time service via the Internet), which the associating means uses to get the time and/or date stamp that is used to mark the first information and the second information.

Marking the first information and the second information with a time and/or date stamp provides the advantage of, for example, allowing an entity viewing an image of the passenger component of the elevator 13 (contained in the first information) to readily determine the status of the elevator 13 at an instant when the image was captured. This is achieved by checking for the same or similar time and/or date stamps in the first information and the second information.

In addition to the obtaining means and the associating means, the building server 3 comprises an

internal storage means in the form of a database. In the present embodiment, the database is a MySQL database from MySQL AB. The building server 3 uses the storage means to store the first information, second information and the association. The building server 3 stores the information in the storage means in a format that accords with an extensible mark-up language (XML).

It is envisaged that in an alternative embodiment of the present invention, the system 1 would make the first information, second information and the association available in real-time to a call centre before the information (first and second) and the association are placed into the storage means.

The building server 3 comprises an access means that enables an entity to gain access to the storage means in order to access and retrieve the first information, second information and the association. Essentially, the access means is in the form of hardware/software (forming, for example, a web site) that enables the entity to log onto the building server 3 either via a local area network or the Internet and retrieve the first information, second information and the association from the storage means.

Typically, the entity logging onto the building server 3 is, for example, a security monitoring system used by a building manager to monitor the elevator 13. The monitoring system is arranged to present the first information and the second information to the building manager via a computer screen.

It will be appreciated by those skilled in the art that whilst the embodiment of the present invention has been described with reference to an elevator, the present invention has application to other transportation devices such as escalators and moving walkways.

Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. It should be understood that the invention includes all such variations and modifications which fall within the spirit and scope of the invention.
