## Background
The present application relates to a system, a passenger train, a method and to a software product that are configured for assisting a passenger in monitoring luggage in luggage compartment of a passenger train.
BACKGROUND ART
Passenger trains typically have a number of rail cars with passenger seats and luggage compartments in each of the rail cars. Passengers deposit their luggage in one of the luggage compartments and take a seat close to or less close to the luggage compartment. Passengers may during the journey visit the restroom or visit the restaurant in another railcar and made during these visits not be able to attend their luggage. If such visit coincides with a stop at a railway station there is a risk that a third-party removes and misappropriates the passenger's luggage. Therefore, passengers may feel uncomfortable leaving their luggage unattended or at of sight.
Patent Application US 2009/0276089 A1 describes an apparatus and a method for dispensing a luggage recognition label having an RFID device associated therewith that allows a passenger and/or a passenger carrier to identify and track their luggage during travel, provide access to a secure network for storing customer and travel information including a luggage inventory and itinerary information. Upon dispensing the label, the association of the unique identification code within the reader network allows access to and maintenance of information that will allow tracking of the passenger's bag. A software program running on a personal computer is designed to interface with a portable transponder and a reader. In one embodiment readers are placed within the cargo hold of a plane such that a traveler can access information regarding the location of their bag on the airplane. The reader on the plane will identify when the bag has been placed on and removed from the plane. A communication to the traveler may be made so that a traveler is assured of the location of their bag at any point in time from check-in, embarking at the point of departure, to disembarking at the point of destination. Communication is carried out wirelessly using transponders.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
In the following, example embodiments of the passenger train, system, method and software product, will be described in detail and with reference to the attached drawings.
FIGS. 1 and 2 show a passenger train 1 with a railcar 8 and a seating arrangement with a plurality of seats 5. The seats 5 are placed in a fixed arrangement and preferably said passenger seats 5 are numbered. The passenger train 1 is provided with doors 3,4 on both sides of the passenger train 1 for allowing passengers to embark and disembark the passenger train 1 when the passenger train 1 stops at a train station. One or more luggage compartments 8 is provided in the train and preferably distributed over the rail cars 8.
A train server 2 is provided on board of the passenger train 1. The train server 2 includes a processor, memory, a wireless access point 9, such as a Wi-Fi hotspot and software for operating the train server. The wireless access point 9 provides for a wireless network in and around the train that can be accessed by a mobile device used by a passenger 6 in order to give passengers access to the train server 2. The luggage item 16 has an RFID tag 20 attached thereto.
The train server 2 is also provided with a wireless modem 15 for wirelessly connecting to a wide area network, such as via cells 14 of a mobile data network (e.g. 3G or 4 g) that connects to the Internet.
The train server 2 is configured for intermittent connection to the wide area network, i.e. it does not need to be continuously connected to the wide area network or to the Internet. One of the reasons for the train server 2 to connect to a wide area network is to establish data communication with a server that includes an online database having stored therein train configuration, train numbers seating arrangements, seat numbering, seat occupancy, train schedules, journey bookings, seat reservations, issued luggage RFID tags, etc. The train server 2 runs RFID hardware and the Software API.
The train server 2 is configured to attempt to connect with the server 2 regularly so as to update its own record of issued RFID luggage tags and the passengers 6 and their mobile devices 7 associated therewith. The train server 2 does not need to be on line (connected to the wider network/Internet) continuously in order to carry out its functionality properly.
A reader 23 for detecting and reading wireless non-contact use of radio-frequency tags (RFID reader) (RFID door frame scanner) is provided in or at the luggage compartment 11, preferably near a side or in the back of the luggage compartment 11. The RFID reader 23 is placed such that it can detect and read RFID tags 20 attached to a piece of luggage 16 that is placed in the luggage compartment 11. The RFID reader 23 is in an embodiment an active reader for reading passive tags 20.
FIG. 2 shows the train stopped next to a platform 10 of a railway station. FIG. 2 also shows the layout of the train 1 with railcars 8 and passenger seats 5 and luggage compartments 11 arranged therein.
FIG. 3 illustrates a diagram of components involved in an embodiment of the system and method. The luggage alert system is based on three different concept components, namely a preferably active RFID scanner 23 that can for example be arranged close to a doorframe of a luggage compartment 11. In other embodiments the RFID scanner 23 is arranged in or at another location that is suitable for detecting the presence of an RFID luggage tag in the luggage compartment 11. Another component is the RFID luggage tag 20 that can be in the form of an RFID chip sticker tag. A further component of the alarm system is a software product in the form of an app 30 on a mobile device 7 of a passenger 6 as a monitor.
FIG. 4 shows the system architecture according to an embodiment. The system architecture is based RFID tags 20 and an RFID reader 23. The RFID luggage tags 20 are in an embodiment passive tags. In an embodiment the RFID luggage tags 20 are tamper proof tags. In an embodiment the RFID luggage tags 20 are read only tags. The RFID reader 23 is connected to the train server 2 and the train server runs the RFID hardware/software API 22. The online app software back and 35 runs on the mobile device 7 and the off-line/online train app software 33 runs on the train server 2.
FIGS. 5 to 7 illustrate an example embodiment of a method and illustrate the operation of the system, the software product 30 and the passenger train 1. At the start of the usage flow the passenger 6 buys a ticket online using a personal computer and pays e.g. with a credit card. The user 6 connects to a server (not shown) that issues a ticket and issues an RFID tag 20 and sends the RFID tag 20 through the mail to the passenger. In the next step the passenger scans the unique optical (QR) code 37 that is enclosed with the RFID tag with his her mobile device 7 using the app 30. (As shown in FIG. 5, train tickets, for passenger train journeys can be provided with an individual optical machine readable code 27). The optical machine readable code 37 code provides the app 30 on the mobile device 7 with information identifying the RFID tag 20 and thus associates the mobile device 7 to the RFID tag 20. Next, the passenger attaches the matched RFID tag (sticker) to his or her suitcase or other piece of luggage 16. The mobile device 7 communicates its association with the RFID tag 20 to a (server not shown) via wide-area network. The train server 20 is in regular application with the server and thus informed of the issuance of an RFID tag 20 and of the mobile device 7 associated therewith. In an mother embodiment, the mobile device 7 informs the train server of its association with the RFIF luggage tag 20 upon establishing connection with the train server 2 via the local area wireless network provided by the wireless network access point 9.
Next, the passenger 6 boards a train and thereafter the passenger 6 places the luggage item 16 in the luggage compartment 11. During this process the RFID scanner 23 registers the RFID tag on the luggage and communicates this registration and the identification of the RFID tag 20 to the train server 2. Thereupon, the train server 2 checks in his database which mobile device 7 is associated with the identified RFID tag 20. After the train server 2 has looked up the associated mobile device 7, it sends via the wireless network a message to the mobile device 7 that the train server 2 has registered that an item of luggage 16 has been deposited in a particular luggage compartment 11. Upon receipt of this message from the train server 2 the app 30 on the mobile device 7 informs the user/passenger 6 to confirm the luggage deposit. When the user/passenger 6 confirms the deposit the app 30 sends a message via the wireless network to the train server 2 confirming the deposit. During this process or after this process the passenger 6 takes his or her seat.
The train server 2 monitors the presence of the RFID tag 20 until the RFID reader 23 ceases to detect the presence of the RFID tag 20. When the RFID reader 23 ceases to detect the presence of the RFID tag 20 the train server 2 sends a message to the mobile device 7 to inform the user that the luggage has been removed and the luggage item 16 is no longer considered as deposited in the luggage compartment 11. The app 30 on the mobile device 7 gives an alarm or an alert and asks the passenger 6 to confirm that he or she has removed his or her luggage item 16 from the luggage compartment 11. Thus, in case of removal of luggage, also when done by an unauthorized third party, the passenger 6 is alerted about the change of status. If the passenger 6 was indeed this embarking the passenger train 1 the app 30 on the mobile device 7 allows the passenger to confirm to the train server 2 that the luggage was a righteously removed.
At least one computer on board the passenger train 1 runs the train server 2.
The same or another computer runs the also offline/online in train app software on media server 37, the RFID hardware/software API and the online software app back end.
The various components of the system architecture communicate with one another via a local or wide area network, including wireless connections.
The online app software backend 35 provides online service to mobile devices 7 of passengers.
The mobile device 7, such as a smart phone is configured with a display and a camera. A luggage alarm app 30 is installed on the mobile device 7, and its code is stored on a memory of said mobile device 7 as a software product. The luggage alarm app 30 provides the functionality required for assisting a passenger in monitoring his or her luggage item 16 during a train journey.
The wireless network is in an embodiment a local network area such as e.g. a WiFi network and/or wide area network such as e.g. a 3G or a 4G network.
Although the teaching of this application has been described in detail for purpose of illustration, it is understood that such detail is solely for that purpose, and variations can be made therein by those skilled in the art without departing from the scope of the teaching of this application.
