Definitions
- Security system method for issuing an alarm signal, bus, use of a security system
- the invention relates to a security system, a bus which comprises a security system, and the use of a security system.
- Anti-theft security systems such as electronic article surveillance (EAS), which include electromagnetic (EM), radio frequency (RF) and acousto-magnetic (AM) systems, are used.
- EAS electronic article surveillance
- EM electromagnetic
- RF radio frequency
- AM acousto-magnetic
- the anti-theft security devices which can be fastened to the goods to be secured can be recognized by detector units which are mostly arranged at the exits of sales areas.
- the detector units are set up to emit an acoustic and / or visual warning signal if a theft protection device is located in the detection area between two detector units, which are usually arranged at a distance of, for example, up to 2 m or 4 m from each other.
- the disadvantage of the aforementioned anti-theft device is therefore that detection outside the detection range of the detector units is not possible. If, for example, the publicly accessible area to be secured is not structurally delimited, i.e. there are no defined exits, the entire area would have to be encompassed with detector units in order to provide effective protection against theft guarantee. This is not only relatively expensive, since many detector units are required, but is usually not structurally possible, in particular if the area to be secured is not defined locally, for example around a mobile sales booth. This is the case, for example, with mobile sales stands. In these there is usually a display of goods outside the field of vision of sellers, which enables these goods to be stolen by unauthorized persons.
- Thefts in retail stores or personal luggage cause great financial and personal damage to their owners.
- the theft of personal items of luggage can also mean a loss of intangible goods, such as irreplaceable personal items, or a loss of personal data if, for example, a laptop or a cell phone is in the item of luggage.
- a security system which comprises a central unit, at least one security unit, which is connected to the central unit via a wireless connection and comprises a security unit-receiving unit, and a predetermined security zone which extends around the central unit extends and in which there is the wireless connection between the central unit and the at least one security unit.
- the central unit comprises a central unit transmission unit, which is set up to send a status query signal to the at least one security unit via the wireless connection, the security system being set up to use the presence and / or content of the status query signal to recognize whether the at least one security unit is located within the security zone or not.
- the security system according to the invention comprises an alarm generation unit which is set up to generate an alarm signal when it has been recognized that the at least one security unit is located outside the security zone.
- the presence of the predetermined security zone in the security system makes it possible to determine precisely whether the at least one security unit is located within this security zone or not.
- the securing unit can also be designed to be detachably attached to or in an object.
- the security system can determine whether the object is located within the security zone.
- a structural delimitation of the security zone, i.e. the area to be secured, is therefore not necessary.
- the detection of whether the at least one security unit is in the security zone can be done by the central unit sending the status request signal permanently or at a certain transmission frequency by means of the central unit transmitting unit, and the security unit receiving the status request signal by means of the security unit receiving unit.
- the security system can recognize that the at least one security unit is located within the security zone, whereas a lack of the status query signal can indicate that the at least one security unit is not within the security zone is located.
- the absence or non-presence of the status query signal for a predetermined period of time can indicate that the at least one security unit is not located within the security zone.
- a faulty alarm signal for example due to a signal disturbance, can be avoided by means of the predetermined period of time.
- the alarm generation unit can be comprised by the central unit or the at least one security unit or a mobile terminal to be defined later. It can output an alarm signal assigned to the at least one security unit when it has been recognized that the at least one security unit is located outside the security zone.
- the alarm signal can be an acoustic signal, a visual signal and / or a digital signal.
- the alarm signal can be generated by the central unit and / or the security unit and / or the mobile terminal.
- the security unit can be set up to generate the alarm signal within a period of less than one second. If, for example, the security unit receiving unit does not receive a status query signal from the central unit within the predetermined time period, it can inform the alarm generating unit about this so that it can generate the alarm signal immediately.
- An effective avoidance of theft of an object secured with the at least one security unit can be achieved if the at least one security unit can itself output an alarm signal. It can thus be indicated to the environment that the object secured with the at least one security unit is or has been removed from the security zone in an undesired manner.
- the at least one security unit therefore preferably has the alarm generation unit which is set up to generate a security unit alarm signal when the at least one security unit has recognized that it is located outside the security zone.
- the security unit alarm signal can be an acoustic signal, a visual signal and / or a digital signal.
- the alarm generation unit of the at least one security unit can be set up to output the alarm signal if the security unit no longer has received a status query signal from the central unit within a predefined period of time, for example a period of less than one second.
- a faulty alarm signal for example due to a signal disturbance, can be avoided by means of the predefined period of time. This configuration is particularly advantageous when a decision is made on the basis of the presence of the status query signal as to whether the at least one security unit is located outside the security zone.
- the at least one security unit further comprises a security unit transmitting unit which is set up to send a status information signal
- the central unit comprises a central unit receiving unit, which is set up to receive the status information signal from the at least one security unit.
- the detection of whether the at least one security unit is located in the security zone can be done by the at least one security unit sending the status information signal permanently or at a certain transmission frequency by means of the security unit transmitting unit, and the central unit receiving the status information signal by means of the central unit receiving unit.
- the security system can recognize that the at least one security unit is located within the security zone, whereas a lack of the status information signal can indicate that the at least one security unit is not within the security zone is located.
- the absence or non-presence of the status information signal for a predetermined period of time can indicate that the at least one security unit is not located within the security zone.
- a faulty alarm signal for example due to a signal disturbance, can be avoided by means of the predetermined period of time.
- the status information signal can contain information about where the at least one security unit is located.
- This information can, for example, be a Be the reception strength of the status information signal or position information.
- the central unit can have the alarm generating unit which is set up to generate a security unit alarm signal when the at least one security unit has recognized that it is located outside the security zone. Consequently, the alarm generating unit can be present both in the at least one security unit and in the central unit.
- the security zone is defined by the range achievable by means of the wireless connection, within which signals can be transmitted, and this range is defined in such a way by a transmission power of the central unit transmitting unit and / and a detection rate of the central unit receiving unit that this is smaller than 40 m, preferably smaller than 30 m.
- a range of 40 m (meters) around the transmitter unit can be achieved with conventional standard components.
- some applications require a smaller backup zone extension.
- a shop area used for selling goods can only have a circumference of 20 m or 10 m.
- an extension of 5 m to 35 m can be advantageous, on the one hand to have a sufficiently large area for loading luggage within the security zone and, on the other hand, to allow the item to be stolen quickly recognize and, if desired, prevent.
- a smaller security zone here for example a range of 5 m, enables the theft of the object by an unauthorized person to be detected more quickly.
- the range that can be achieved by means of the wireless connection can be set. In this way, the extension of the security zone can be adapted to the respective application and the security system can be used flexibly for different applications.
- the range of the wireless connection can determine the extent of the security zone. It goes without saying that in this way, based on the presence of the status information signal and / or the status query signal, it can be seen whether the at least one security unit is located within the security zone, since signal transmission by means of the wireless connection can no longer be possible outside the range of the wireless connection.
- the security system can also include a mobile terminal.
- the mobile terminal can be connected to the central unit and / or the at least one security unit and preferably comprises a receiving unit which is set up to receive the status information signal and / or the alarm signal and to output an alarm message based thereon, and a display device which is set up to display the alarm message and / or to display whether the at least one security unit is located within the security zone or not. Since a mobile terminal is usually carried close to a person, this person can be informed within a very short time, for example within a few seconds, that an object secured with the at least one security unit is not located within the security zone. Furthermore, it can increase the comfort of the person owning the mobile terminal if the person is shown that the at least one security unit is located within the security zone.
- the mobile terminal comprises the or a further alarm generating unit and the central unit transmits the information about the non-existence of the status information signal by means of a wireless connection to the alarm generating unit of the mobile terminal. It is also possible, as an alternative or in addition, for the security unit to transmit the information about the non-existence of the status query signal to the mobile terminal.
- the attention of the owner of the mobile terminal can be increased if the alarm message is a push-up message which is displayed by the display device.
- the mobile terminal can also include application software by means of which the at least one security unit can be assigned to a specific object to be secured or to an attribute assigned to it, e.g. its owner. This assignment can be made temporarily.
- the at least one security unit can be assigned to a person to be transported by the bus and / or to a specific seat in the bus for a duration of the travel time. If the mobile terminal device has a GPS receiver, the at least one security unit can, for example, be assigned to a person to be transported by bus until the mobile terminal device indicates that this person has reached a travel destination assigned to him.
- the central unit and / or the at least one security unit can be set up to repeatedly send a signal assigned to a security unit to the mobile terminal by means of the wireless connection. That is, communication between the central unit, the at least one security unit and the mobile terminal preferably takes place via the wireless Connection. It goes without saying that in this way a signal assigned to the at least one security unit can only be received by the mobile terminal when it is in a transmission or reception area of the wireless connection. This enables a simple design of the mobile terminal as well as the central unit and / or the at least one security unit, since all transmitting and receiving units can only be set up to receive signals according to a standard protocol.
- the central unit and / or the at least one security unit can be set up to repeatedly send a signal assigned to a security unit to the mobile terminal by means of a further wireless connection. That is, the further wireless connection can differ from the wireless connection, which is present at least within the security zone, and preferably also enable signal transmission outside the security zone.
- the further wireless connection can be, for example, a cellular connection and the mobile terminal can, for example, be a cellular device that can receive cellular data.
- the central unit and the at least one security unit preferably comprises a transmission unit designed to transmit mobile radio signals.
- the signal assigned to the security unit can be the status information signal, which enables information on whether the at least one security unit is located within the security zone or not.
- the application software of the mobile terminal can be set up to use the presence and / or content of the status information signal of the at least one To recognize security unit whether the at least one security unit is located within the security zone or not.
- the signal assigned to the security unit can be the alarm signal if it has previously been recognized that the at least one security unit is located outside the security zone.
- the mobile terminal can be, for example, a smartphone belonging to the owner of an object to be secured with the at least one security unit.
- the mobile terminal can, however, also be assigned to an operator of the security system, for example a bus driver, who can use the mobile terminal and application software to assign the at least one security unit to an object or its owner. That is, the application software of the mobile terminal can be set up to assign the at least one security unit to an object or its owner.
- the at least one security unit can be assigned to an object to be secured with it or to attributes assigned to it, such as its owner, by coupling the mobile terminal to the at least one security unit.
- the connection between the mobile terminal and the at least one security unit is preferably a secure connection, the mobile terminal preferably having a coupling means for coupling the at least one security unit to the mobile terminal and the at least one security unit having a coupling element. It goes without saying that the coupling can also be decoupled again, as a result of which the securing unit can be used again.
- a possible coupling element is, for example, a barcode on the at least one security unit.
- the barcode can be assigned a Mac address or a standard name, for example a Bluetooth Default names, be linked.
- a signal via near field communication (NFC) or a signal via identification using electromagnetic waves (RFID) can represent a coupling element.
- Corresponding coupling means can accordingly be a barcode scanner, a Bluetooth receiver, an NFC or an RFID signal reader.
- a coupling between the mobile terminal and the at least one security unit can additionally or alternatively also take place by means of the central unit.
- the central unit can output or display an identification assigned to the at least one security unit, for example a name or a number, in response to a manual input. A person can then remember this identification.
- a transmission unit of the mobile terminal and / or the security unit transmission unit of the at least one security unit is / are set up to send coupling information to the central unit, wherein the central unit can be set up to transmit the coupling information by means of the coupling information receiving unit and to store it in a memory.
- the memory for the coupling information can be arranged in the central unit or a server comprised by the security system, to which, for example, the central unit and / or the mobile terminal can access.
- the coupling information can be sent to the central unit and / or the server by means of the wireless connection or the further wireless connection.
- an owner of an object to be secured can bring the coupling means of his mobile terminal, for example a Bluetooth receiver, within range of the coupling element of the at least one security unit, for example a Bluetooth standard name, and this coupling information to the central unit and / or the server.
- the central unit can also be set up to send the alarm signal to the mobile terminal which is coupled to the at least one security unit. Furthermore, the alarm signal can be sent to several mobile terminals if these are mobile terminals which are coupled to the at least one security unit.
- the mobile terminal that is assigned to an operator of the security system can have access rights to all of the plurality of security units, whereas the mobile terminal of an owner of an object to be secured can only have access rights to the security unit assigned to it.
- the at least one fuse unit can have an internal, preferably rechargeable, energy storage unit, by means of which the energy required for the operation of the fuse unit can be provided.
- the energy storage unit can be a battery.
- the at least one securing unit can have a locking mechanism which can be unlocked in response to an unlocking signal received by the securing unit.
- the unlocking signal is preferably an encrypted signal and can, for example, from the mobile terminal which is coupled to the security unit to be unlocked, or from the mobile terminal of an operator corresponding access rights are sent to the security unit to be unlocked.
- the at least one securing unit can, for example, be attached to an item of luggage, for example a suitcase, a backpack, a handbag or the like, in such a way that the item of luggage is closed by it.
- opening of a zipper can be prevented by means of the at least one securing unit.
- the unlocking signal can be transmitted to and received by the security unit by means of the wireless connection and / or the further wireless connection.
- the unlocking signal can be encrypted using an encryption standard, e.g. AES (advanced encryption standard), e.g. encryption length of 128, 160, 192, 224 or 256 bits.
- the encryption length is preferably 128 bits.
- the at least one securing unit can be set up to receive the unlocking signal via the wireless connection or the further wireless connection.
- the unlocking signal can be sent from the central unit or the mobile terminal.
- Each security can include a special opening token, which is stored, for example, on a server comprised by the security system. If the at least one security unit is to be opened by means of the mobile terminal device, the mobile terminal device can receive this opening token via the wireless connection or the further wireless connection using the application software. The mobile terminal can then send the opening token to the at least one security unit via the wireless connection or the further wireless connection, for example by means of Bluetooth and / or NFC, and thus unlock the locking mechanism.
- the locking mechanism can comprise an electromechanical actuator, which can be actuated upon receipt of the unlocking signal in such a way that it can unlock the locking mechanism.
- the energy storage unit of the at least one fuse unit can provide the energy necessary for actuating the actuator.
- the locking mechanism can be designed as described in the patent application of the same applicant with the application number 102019204779.3, in which a theft protection device that can be attached to objects such as textiles is described, which can be coupled to a mobile device of a user and to a wirelessly received unlocking signal from this can be unlocked.
- a product based on this principle is also already being sold by Rapitag GmbH and used in retail outlets to simplify the payment process.
- the customer can use his mobile device and a corresponding application software to connect to the anti-theft device attached to an object via a wireless connection and make a payment process, after which the anti-theft device can be unlocked.
- patent application US 2016/0260303 A1 describes an unlocking of a security tag by a customer, in which a wireless command signal is sent to the security tag, whereupon an actuator in the security tag is activated and opens the lock of the security tag.
- the at least one securing unit can additionally or alternatively have an input device by means of which the unlocking signal can be generated.
- the input device can be a button or a touchpad, by means of which the unlocking signal can be input in the form of a code.
- the code can be a numeric code, a A numerical code or a combination thereof or a specific button press frequency, such as a string of Morse codes.
- the at least one security unit can also have a lock unit, by means of which the locking mechanism can be opened manually using a corresponding key.
- the at least one security unit can be switched to an activated state and a deactivated state, the alarm generating unit preferably not outputting an alarm signal in the deactivated state of the at least one security unit, even if the at least one security unit is not located within the security zone , and the security unit transmission unit is preferably set up to send out at least one deactivation signal. In this way, false signals can be avoided and the sending of signals and the associated energy consumption can be avoided.
- the deactivation signal can inform the central unit and / or the mobile terminal about the deactivated state of the at least one security unit.
- an alarm signal can be prevented which would otherwise be triggered by the security system, e.g. the central unit, the security unit and / or the mobile terminal, if the presence and / or the content of the status information signal shows that the security unit is not within the Backup zone is located.
- the at least one fuse unit can be in the deactivated state during a charging process of the energy storage unit.
- the central unit can serve as a charging station for the security unit and the at least one security unit in the deactivated state if it is in the charging station.
- the or a charging station for the energy storage unit can be connected by means of an onboard supply of a bus, for example can be supplied with energy by means of a 12 V connection of the bus.
- the at least one security unit can be deactivated remotely if the central unit and / or the mobile terminal sends a signal for remote deactivation to the at least one security unit.
- An input by the mobile terminal and / or the central unit can, for example, specifically activate or deactivate one, several or all security units.
- the at least one security unit can be switched to the deactivated state by means of an instruction from the central unit and / or the mobile terminal during a long journey without a break, during which the bus is locked and there is no risk of theft. In this way, the energy consumption of the at least one fuse unit can be reduced.
- unlocking of the locking mechanism can be prevented in the deactivated state.
- the wireless connection can be one of a Bluetooth connection, a WLAN connection, a cellular connection and an infrared connection.
- the further wireless connection can be designed in the same way.
- connection technologies are established and known for stable signal transmission.
- infrared has the disadvantage that visual contact between the transmitter and receiver is required for the wireless connection. Therefore, an infrared connection can only be used to a limited extent for applications in which obstacles, such as bus walls, have to be overcome.
- Bluetooth and WLAN are common wireless connection technologies which have a sufficient connection range even through obstacles such as bus walls and, in contrast to cellular connections, do not depend on the positioning of transmission masts.
- the wireless connection can be Bluetooth and the further wireless connection can be cellular radio.
- the position of the at least one security unit can be determined by means of GPS or cellular radio.
- the security system comprises a plurality of security units, each of which has a personal identification, wherein the central unit can be configured to generate the status query signal and / or the status information signal based on the personal identification of each security unit of one of the security units from the plurality of fuse units.
- Each of the plurality of fuse units preferably corresponds to the at least one fuse unit described above.

- Each of the plurality of security units can also be coupled to the mobile terminal.
- the mobile terminal can be connected to a selected one of the plurality of security units by means of the personal identification.
- the connection can be secured as previously described.
- the identification can preferably be implemented by means of a MAC address assigned to each of the security units or a permanently programmed and unchangeable standard name assigned to each of the security units or an RFID chip present in each of the security units.
- Bluetooth can be used together with a permanently programmed and unchangeable standard name.
- the security system comprises a number of security units which corresponds to the number of seats in a bus, twice the number of seats in a bus or a number in between. In this way, one or two pieces of luggage of a passenger traveling on the bus can be provided with a securing unit.
- the security zone to be secured is larger than the range of the wireless connection or should this deviate from an approximately round shape of the security zone. It can therefore be advantageous if the central unit comprises a plurality of sub-units, each of which comprises a transmission unit which is set up to send the status query signal to the at least one security unit via the wireless connection, and a receiving unit which is set up to do so to receive the status information signal from the at least one security unit, wherein the alarm generation unit is set up to generate an alarm signal, if from one, preferably it has been recognized by all, the plurality of sub-units on the basis of the presence and / or the content of the status information signal from the at least one security unit that the at least one security unit is located outside the security zone.
- Each sub-unit can be configured to use the status information signal of the at least one security unit to recognize whether the at least one security unit is located within the security zone or not, and each sub-unit is configured to generate an alarm signal.
- a corresponding status information signal from one of the sub-units can be sufficient that no alarm signal is generated by the alarm generation unit.

- the sub-units can be connected to one another by means of the wireless connection or a wired connection.
- a wired, for example cabled, connection is advantageous in the case of permanent installation of the subunits.
- three or more sub-units can be permanently installed in a bus and possibly connected to one another by wire.
- the central unit can be formed from at least three, preferably four, sub-units, which are arranged at a distance from one another and whose respective receiving units receive the status information signal from the at least one security unit, and the central unit can be set up to use previously known positions of the respective receiving units and the Signal strength of the status information signals to determine a position of the at least one security unit by means of triangulation.

If the security system detects that the security unit 14, 114 is not located within the security zone 18, 118, an alarm, for example the alarm signal, can be output. Otherwise, the security system can again determine whether the security unit 14, 114 is located within the security zone 18, 118 or not.
- the alarm generation unit 24 can generate the alarm signal 26.
- a “self-check-in” by a passenger can also take place via the security system 10, 100.
- a coupling for example using the coupling means and coupling elements, between the securing unit 14, 144 and an attribute that can be assigned to the object 56 can be carried out successfully and the passenger can thus check-in for the bus trip previously booked by him automatically, i.e. without further action, for example a bus driver.
- the user software of the passenger's mobile terminal 32, 132 links a ticket for a travel route with the bus or the security unit assigned to the bus and thus establishes that the passenger is present and the route will begin, creating a “self -Checkin “of the passenger can be triggered and carried out automatically. If necessary, the passenger can initiate and / or confirm the “self-check-in” himself after the security unit has been linked to an attribute that can be assigned to the object, such as the passenger and his / her travel ticket.
