Description

The present invention relates to a release control device for an effector and a method for release control for an effector.

Effectors are used in the military field for defense and attack. Not every nation or conflict party has the capacity to make its own effectors.

The distribution of effectors is therefore usually controlled by controlled export or military aid to allied or friendly troops.

However, after the first edition of effectors, e.g. the delivery to allied troops, not to be sure which way the effectors continue to take. Thus, an uncontrolled spread of the effectors, e.g. through illicit trade, loss of effectors or changes in the power relations in partner nations cause other powers or groups, other than those originally intended, to be seized and used by the effectors.

It is desirable to prevent the unauthorized use of effectors.

A use of an effector by an unauthorized person is in the US 5,603,179 prevented, for example, by a fingerprint sensor that releases the effector only upon detection of the fingerprint of an authorized person.

The KR 101 500 479 B1 Figure 11 shows a system in which an RFID tag is used to enable the use of an effector for a user as long as the RFID tag is in proximity to the effector.

Against this background, the present invention has the object to provide an improved way to control the use of effectors.

According to the invention, this object is achieved by a release control device having the features of patent claim 1, and by a method for release control having the features of patent claim 9.

Accordingly, a release control device is provided. The release control device comprises a controllable blocking device which is designed to controllably lock or unlock the effector for use, an input interface which is designed to detect a release code and a control device which is designed to control the blocking device in dependence on the detected release code, to release the effector for use for a predetermined period of time, the predetermined period being determined by the content of the release code.

In addition, a method for release control is provided. The release control method comprises the steps of detecting a release code for the effector, releasing the effector for use for a predetermined period of time depending on the release code, the predetermined period being determined by the content of the release code.

The present invention is based on the recognition that individual unlocking of an effector by the respective user is expensive. For example, an input field and a display for a PIN code must be provided on the effector, or the user could lose an RFID tag which activates the effector.

The present invention therefore provides that an effector is enabled by a code for a predetermined period of time. For this purpose, a controllable locking device is provided, which is locked in the normal state, that works unlocking. The effector is thus unlocked only with appropriate control of the locking device by the controller and released for use.

The locking device can be used e.g. have mechanical locking elements, e.g. Mechanically block a trigger of an effector. Furthermore, the blocking device may also comprise electrical or electronic blocking elements, which may be e.g. are arranged in particular with effectors with an electronic control within the electronic control and there can block the function of the effector.

If the control device now receives a release code via the input interface, it controls the blocking device in such a way that it releases the effector for a period of time predetermined by the release code. The release control device may be arranged in or at least partially on the effector.

The unlocking, that is, the transmission of the release code to the effector may e.g. at a weapons issue in a military facility or a military camp.

This procedure has the advantage that there is no impairment of the effector during use. Furthermore, the user is also in his freedom of movement, e.g. not restricted by an RFID bracelet or the like.

The release codes may also be managed independently of the users in the present invention. A user does not need to know the release code and thus can not abuse or pass it on.

At the same time, however, it can be ensured that the user can make full use of the effector for the planned duration of his mission. Thus, for example, if an insert with a duration of 2 hours planned, e.g. a patrol, the effector can be unlocked by an appropriate release code for exactly this period. In addition to a period, the release code may e.g. also specify a start time. The effector is then enabled for the specified duration from the specified start time.

The present invention thus enables a very flexible, yet safe handling of effectors.

The term effector may be any type of effector, e.g. be implemented by a person effectors, mobile or remote-controlled effectors, to be operated by multiple people effectors or the like.

Advantageous embodiments and further developments will become apparent from the other dependent claims and from the description with reference to the figures.

According to a development, the input interface may have an electrical input interface. Furthermore, the release code can be embodied as digital code, which can be transmitted digitally to the input interface.

An electrical interface enables the transmission of a large amount of digital data in a short time. The transmission of the release codes can thus not only be digital but at the same time e.g. use an error correction and cryptographic security measures to ensure the correct transmission of the release codes.

As an electrical interface, any type of interface can be considered, which uses electrical signals to transmit the digital data.

For example, such an input interface may be a wired input interface. Such a wired interface may e.g. have a network connection to a sharing server. The release server may be e.g. be stationed in a military camp. Alternatively, however, the server may be e.g. also removed, e.g. in the home country of the respective troops.

In particular, in the remote server, the release codes can be locally separated from the effectors and it can be ensured that the release codes do not get into the wrong hands.

Are used as release codes e.g. Furthermore, time-based one-time passwords can be easily managed via a central server.

When using a server that is not kept near the effectors, e.g. not in a military camp, control over the use of the effectors remains with the operator of the server. Thus, e.g. a state is an allied state effectors, the supplying state can always maintain control of the effectors also disable if the alliance of the two states breaks up.

However, the wired input interface may be e.g. may also be a proprietary interface containing the respective effector e.g. can pair with a disconnecting device. Such an enabling device may e.g. a device that can be stationed in a military camp and performs the activation of the effectors. Such a disconnecting device can store the release codes locally or from the o.g. Retrieve server.

Furthermore, such a disconnecting device may e.g. be connected to a plurality of effectors simultaneously, for example, as long as they hang in a shelf material. The unlocking device can consequently activate any number of effectors at the same time or at the same time transmit corresponding release codes to them.

According to a development, the input interface can have a wireless electrical input interface and the release code can be stored on a wireless contactable data carrier.

The wireless electrical input interface may be e.g. an RFID or NFC interface. Other interfaces, such as Bluetooth or ZigBee are also possible.

Wireless data carriers can e.g. RFID tags, NFC tags or the like. It is understood that e.g. also an electrical device, such as e.g. a tablet PC or a smartphone with an NFC interface can be considered as a wireless disk.

As an alternative or supplement to the wireless interface, an optical interface can be provided which reads the release code, for example, as a QR code or barcode or the like.

To increase the security in the activation of effectors, both the transmission of the activation codes and the content of the release codes can be cryptographically secured.

According to a development, the release codes can each have a digital certificate which has the predetermined period and an identifier of a source of the release code. The controller may be configured to check the digital certificate and to allow the respective release code only to release the use of the effector when the digital certificate has been successfully verified.

Digital certificates offer the possibility of uniquely identifying the source of the release code using cryptographic methods. It can thus be ensured that a received release code also comes from an authorized source.

In addition to digital certificates, other cryptographic measures can also be used to authenticate the release code or the respective counterstay.

For example, bi-directional communication may be provided between the release controller and the source of the release codes, e.g. a so-called challange response procedure can be performed.

In accordance with a further development, the release control device can have a code memory which is designed to store release codes that have already been recorded. The control device may be configured not to allow release codes already registered for a re-release of the effector.

If release codes are stolen, they may also be used by unauthorized persons to unlock an effector.

The fact that in the code memory the release codes already used are stored, a reuse of a release code can be detected and an activation of the effector can be prevented. Furthermore, a number of releases can be stored for the individual release codes. A release code can therefore be used as often as deposited for the respective release code.

According to a further development, the release codes can be designed as time-based one-time codes. The control device can be designed to check the time-based one-time codes and to enable the effector for use as a function of the respective test result.

Time-based one-time codes are codes which are only used once and only for a predetermined period, e.g. 1 minute, 5 minutes or 10 minutes, are valid. For use of one-time codes, the effectors and the source of the one-time codes may receive a start code, on the basis of which the further codes for the respective periods are calculated.

As a source of such release codes, appropriate devices, such as e.g. OTP tokens, or programs may be used e.g. be provided on a tablet PC or smartphone, which calculate the release codes or retrieve from a server.

According to a development, the release control device may have a position determination device, wherein the release code may indicate a usage region. The controller may be configured to enable the effector for use only within the designated usage region.

The position determining means may e.g. a satellite-based position-determining device, e.g. using the GPS or Glonass system. Of course, the position determining means may e.g. also other sources, such as Inertial sensors associated with a dead reckoning called use. The position determination via e.g. UMTS, LTE or WLAN networks is also possible.

An exact position determination e.g. to less centimeters is not necessary for the position-dependent activation of an effector. Rather, a rough determination is e.g. sufficient for several meters or several hundred meters, as the activation codes can indicate usage regions that cover larger areas. Furthermore, the freedom of movement of one's own units should not be restricted. Thus, rather than very small areas, such as areas of use, e.g. individual streets or buildings, but rather entire cities, regions or countries.

According to a development, the release control device may comprise a communication device which is designed to receive the release codes via a wireless communication system and to provide them to the control device.

Usually, military operations are planned prior to implementation and an operational period is planned or estimated. However, it can happen that units are stopped during a mission and the deployment is prolonged.

In such cases, a wireless communication system, e.g. a satellite-based communication system, GSM, UMTS, LTE, WIFI, WLAN or the like, a new activation code are transmitted to the effector.

Furthermore, it can be provided that a period of time specified by an activation code is automatically extended by a predetermined duration if the effector has not received a return code until the end of the predetermined period. The return code may e.g. via an RFID tag upon the return of the effector e.g. be transmitted to the effector in a military camp. It is understood that the period is e.g. can only be extended up to a certain maximum duration in order not to avoid the protection by the release control device according to the invention.

Furthermore, the predetermined by an unlock code period can be automatically extended when the effector is actively used. For example, it must be prevented that an effector is turned off when a soldier is involved in a battle and so can not finish the mission within the estimated time.

The above embodiments and developments can, if appropriate, combine with each other as desired. Further possible refinements, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

The accompanying figures are intended to convey a further understanding of the embodiments of the invention. They illustrate embodiments and, together with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the stated advantages will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale to each other.

In the figures of the drawing are the same, functionally identical and same-acting elements, features and components - unless otherwise stated - each with the same reference numerals incremented by 100 provided.

1 shows a block diagram of a release control device 100 for an effector 101 , The release control device 100 is in the effector 101 arranged. It is understood that in further embodiments, at least parts of the release control device 100 also outside the effector 101 can be arranged.

The release control device 100 has a controllable locking device 102 on that with a control device 104 is coupled. The control device 104 is also provided with an input interface 103 coupled.

The locking device 102 For example, it may be a mechanical locking device that mechanically triggers the effector 101 prevents when the effector 101 should be blocked. For example, a mechanical locking device 102 have a movable pin, a trigger of the effector 101 blocked. It is understood that, depending on the nature of the effector 101 other mechanical arrangements as a barrier device 102 can be used.

The locking device 102 can also be used as an electrical locking device 102 or be designed as a software function. Solves an effector 101 electrically off, the locking device can 102 to lock the effector 101 eg a power supply to the trigger element of the effector 101 interrupt. Will the effector 101 Controlled by a digital controller, such as a microcontroller or the like, the locking device 102 For example, be a function in a firmware of the controller, the specific functions of the effector 101 releases or blocks.

The input interface 103 the release control device 100 is designed as an RFID interface by an RFID tag 106 a release code 105 can receive.

Will the RFID tag 106 near the input interface 103 brought, this recognizes the RFID tag 106 and reads the release code 105 from the RFID tag 106 out.

The input interface 103 directs the release code 105 to the controller 104 further, which depends on the release code 105 the locking device 102 such that the effector 101 is unlocked for use for a given period of time. The specified period is determined by the release code 105 certainly.

For example, the effector 101 a long or short weapon issued in the material issue of a military camp in a deployment area to soldiers. By different release codes 105 can be before or at the output of the effector 101 How long the effector will be set 101 will be active or usable. So can the duration of the release of the effector 101 adapted to the planned duration of use. For example, in the material output different RFID tags 106 be held, the different release codes 105 contain. The staff in the material issue can be so very easy by using the respective RFID tags 106 the release of the respective effector 101 to adjust. In order to avoid or detect a faulty release, for example, in the material issue for the soldiers, a reader can be provided, on which the soldiers can read, how long their effector 101 is unlocked.

It is understood that long or short weapons are merely exemplary effectors 101 are. As an effector 101 However, within the scope of this invention, any agent that is actively used by soldiers, or even any semi-autonomously or autonomously acting agent, may be considered. Examples of such actuators are eg vehicles, aircraft, drones or the like.

The release control device 100 was used in conjunction with an RFID-based input interface 103 shown. It is understood, however, that any other type of digital interface is also possible. Furthermore, instead of the RFID tags 106 For example, a smartphone or tablet PC can be used with an NFC or RFID interface. For example, on a smartphone or tablet PC, an application can use the sharing codes 105 calculate or spend.

2 shows a block diagram of another release control device 200 , The release control device 200 based on the release control device 100 and also has a controllable locking device 202 on that with a control device 204 is coupled up. The control device 204 is also provided with an input interface 203 coupled, also as an RFID-based input interface 203 is trained. However, as a remote station no RFID tag but a tablet PC 206 provided with an RFID or NFC interface.

The release control device 200 also has a with the control device 204 coupled code memory 208 on. In the code memory 208 stores the controller 204 all previously received release codes 205 ,

After receiving a release code 205 and before the release of the effector 201 checks the control device 204 whether the release code just received 205 already in the code memory 208 is stored. If this is the case, it means that the release code 205 already used.

The control device 204 can use those already used release codes 205 reject and the effector 201 do not unlock. Alternatively, for each of the release codes 205 specify a number that determines how many times a release code will be issued 205 may be used.

The tablet PC 206 Represents a digital certificate 207 ready, which the release codes 205 having. The tablet PC 206 can the digital certificate 207 eg as part of a software installation, with which an application is installed on the tablet PC, the release control of effectors 201 serves. For example, it does not have to be for every release code 205 a separate digital certificate 207 to be provided. Rather, for example, a device certificate for the tablet PC 206 be provided with which the tablet PC 206 at the release control device 200 authenticated. The individual release codes 205 can then be independent of the digital certificate 207 , for example, also cryptographically secured, transmitted.

Because tablet PCs 206 Usually have radio interfaces such as WLAN and Bluetooth, the transmission of the release codes 205 to the effectors 201 also via WLAN or Bluetooth. So can several effectors 201 be achieved at the same time, without this close to the tablet PC 206 to hold, as with RFID or NFC needed.

Of course, the communication between the effectors 201 and the tablet PC 206 also be bidirectional. So can the effectors 201 eg with the tablet PC 206 to register. Of the Tablet PC 206 therefore knows what effectors 201 are within reach. The tablet PC 206 For example, a user can then have a list-based selection of the effectors to be enabled 201 enable. For example, a user can have a whole group of effectors 201 unlock at the same time. Of course, such groups can be stored in advance or the tablet PC 206 be transmitted from the resource planning. For example, it can be ensured that only the amount of effectors planned in the resource planning 201 is unlocked.

Of course, an emergency release can be provided. If, for example, a military camp is attacked, an emergency code can be sent to the individual effectors in the material issue 201 be transmitted, for example, immediately for 24 hours. 48 hours or so unlocks.

3 shows a block diagram of another release control device 300 , The release control device 300 based on the release control device 100 and also has a controllable locking device 302 on that with a control device 304 is coupled. The control device 304 is also provided with an input interface 303 coupled. The input interface 303 is not a wireless interface but a wired interface. The release codes 305 become the release control device 300 from a local sharing facility 309 provided.

Usually become effectors 301 stored in cupboards or shelves in which they sit side by side in a row. In the holders of the effectors 301 Consequently, lines and contacts can be provided, via which the local release device 309 the effectors 301 can contact. In this case, the local release device 309 via data lines with each individual storage space for one of the effectors 301 be connected. The local release device 309 can therefore with all the stored effectors 301 communicate and unlock them. For example, display devices may also be provided at the individual storage places, via which a user the status of the respective effector 301 can be displayed.

For example, a user in a material output can activate several effectors 301 cause and see, for example, by means of a green light, which effectors were unlocked, so that he can select or output them specifically.

The local release device 309 also has a data line 312 on which the local release device 309 with a server (not shown separately) can be coupled. The server can be the local sharing device 309 eg the release codes 305 to transfer. This allows remote access to the effectors 301 to be controlled.

The release control device 300 further comprises a position determination device 310 on that the position of the effector 301 can determine. Furthermore, in the release codes 305 be given in which geographic region of the effector 301 should be unlocked. It can thus be prevented that the effectors 301 be used in other than the intended areas of operation.

Finally, the release control device 300 a communication device 311 on, over which the control device 304 release codes 305 can also receive when the effector 301 is in use. For example, a soldier may be held up by unforeseen events, and his deployment may therefore exceed the intended duration. Of course, the effector should 301 do not turn off in such a case. About the communication device 311 may be the release of the effector 301 be easily extended.

It should be understood that the features of the release control devices shown above 100 . 200 . 300 can be combined with each other as desired.

In the description of the procedural 4 and 5 For better understanding, the reference numerals of the device-based figures are retained.

4 shows a flowchart of a method for release control for an effector 101 . 201 . 301 ,

The method sees the detection S1 of a release code 105 . 205 . 305 for the effector 101 . 201 . 301 in front. Subsequently, the effector 101 . 201 . 301 for use for a given period depending on the release code 105 . 205 . 305 released S2. The specified period is determined by the content of the release code 105 . 205 . 305 , It can therefore by adapting the release codes 105 . 205 . 305 the duration of the release or activation are set.

The release codes 105 . 205 . 305 can be provided as digital codes, for example. In particular, the release codes 105 . 205 . 305 eg a digital certificate 207 . 307 comprising the predetermined period and an identifier of a source of the release code 105 . 205 . 305 having.

When releasing S2 of the effector 101 . 201 . 301 then becomes the digital certificate 207 . 307 checked and the respective release code 105 . 205 . 305 only to release the use of the effector 101 . 201 . 301 admitted if the digital certificate 207 . 307 successfully tested.

The release codes 105 . 205 . 305 can thereby in any way to the effector 101 . 201 . 301 be transmitted. For example, the release codes 105 . 205 . 305 on a wireless contactable data carrier, such as an RFID tag 106 , get saved. Alternatively, the release codes 105 . 205 . 305 wired to the effector 101 . 201 . 301 be transmitted.

5 shows a flow diagram of a further inventive method, which is based on the method of 4 based.

In the method of FIG. 5, the release codes 105 . 205 . 305 additionally be received via a wireless communication system S5. This allows the effectors 101 . 201 . 301 the release codes 105 . 205 . 305 also in the field.

Furthermore, already registered release codes 105 . 205 . 305 stored S3. When releasing S2 of the effector 101 . 201 . 301 then already entered release codes 105 . 205 . 305 eg not for a new release of the effector 101 . 201 . 301 authorized.

Finally, a position of the effector 101 . 201 . 301 determines S4, with the release codes 105 . 205 . 305 specify a usage region. When releasing S2 of the effector 101 . 201 . 301 becomes the effector 101 . 201 . 301 then only for use within the specified region of use is unlocked.
