Abstract

538 042 guard service or an emergency service, which are not shown in Fig. 1 but are indicated on other drawings such as SG ("Security Guard") and ES ("Emergency Service") respectively. This may, for example, be the case when the nature of the alarm action is such that special resources are required, such as a reported burglary attempt, a suspected fire accident or a sudden threat of sudden illness in the guard CT. A similar situation exists with certain types of caregivers CT who do not need regular, scheduled care of the caregiver center CGC but still have some reduction that justifies the existence of a safety terminal TT of safety shells, in case a temporary abnormal situation should arise in the caretaker's home CTRi. In such a case, the security guard CT may not even be a known user of the security center CGC, and the security alarm center TAC must send a request for security alarm guard 2 directly to the alternative security unit without involving the security center CGC. Alternative care units SG, ES usually have thousands of potential CT patients. It is not only uncertain whether they have a copy of the steering wheel key to the caretaker's home CTRi, but also it is at best uncertain whether they are familiar with the correct way to report back to the security alarm center TAC when the alarm transaction is handled. The problem from the security alarm center's TAC perspective, to obtain an effective and reliable monitoring that a security alarm transaction is handled, thus becomes weaker. In the case of security alarms, there is generally expressed room for improvement when it is necessary to report or monitor that a caregiver has acted at a caretaker's home for the purpose of handling an alarm transaction at the caretaker's home. SUMMARY OF THE INVENTION In view of the above, an object of the invention is to solve or at least reduce the problems discussed above.

Description

538042 SECURITY AND ELECTRONIC reading device for use therein, and an associated method to monitor the disposal of A PANIC event-IN A social alarm systems Uppfinningsomradet present invention relates to security alarms, and more particularly, a security alarm system comprising a safety alarm center and a plurality of security terminals fcir using respective care takers at their respective security guard housing, where each security terminal is configured to send a security alarm to the security alarm center when an alarm action occurs at the yard guard home, where the security alarm center is configured to, as a result of the security alarm being received from the security guard terminal, The security alarm center is configured to monitor the receipt of a confirmation of. that the security alarm guard has been carried out, which confirmation indicates that a caregiver has acted at the caretaker's home in order to take care of the alarm.

The invention relates to an associated method for monitoring that a security alarm operation is handled in a security alarm system. Furthermore, the invention also relates to an electronic laser device for use in such a security alarm system.

Background of the Invention As each community now has to deal with an aging population, needs and expectations have been raised about an effective and ever-dignified way of letting older people, as well as people with physical, medical or mental disabilities, remain in their private homes. housing or day care centers, rather than conventional care institutions such as hospitals.

People in the categories above often need regular care or assistance. Such care or such assistance is usually scheduled and performed by staff from a care center, who staff visit the yard staff a number of times a day or week to perform household, medication or care services. However, the need for care or assistance cannot always be anticipated and scheduled in advance; the caregiver may be affected by an accident, sudden illness or other type of situation where immediate reversal of 1,538,042 or assistance is required. Thus, the area for security alarm systems has been developed. An example of a typical security alarm system 10 is shown in Fig. 1.

In the security alarm system 10 according to Fig. 1 there is a security alarm center, TAC ("Telecare Alarm Center"). Furthermore, there are a number of security terminals, TT ("Telecare Terminals"), for the use of the respective caretaker, CT ("Care Takers"), at their respective caretaker residences, CTR ("Care Taker Residence"). (Only one caretaker's home, CTR "a caretaker, CT" and a security terminal, TT "are shown in Fig. 1.) Each individual security terminal, TT, is configured to send a security alarm 1 to the security alarm center when an alarm occurs in the stationary CTR. , in which the security terminal TT, is installed. The alarm action can typically be triggered by the guard CT, activating an alarm button on the security terminal TT, and thereby calling for assistance or care.

The security terminal TT, can typically be in the form of a stationary telephone device which is connected via a communication channel 102 to the security alarm center TAC. The communication channel 102 may typically include a public switched telephone network (PSTN), a mobile telecommunications network (such as GSM, UMTS or LTE), or a wide area network (WAN) (such as an IP broadband network), or combinations of these. Quite often, the safety terminal TT is supplemented by a portable device, such as a wristband worn around the yard taker's wrist. Such a wristband device usually has an alarm button and wireless communication means for transmitting a local alarm signal to the security terminal, which in turn generates and sends the security alarm 1 to the security alarm center TAC.

As shown in Fig. 1, the security alarm center TAC has a security alarm center server, TAC-S, and a security alarm center database, TAC-DB. Upon receipt of the security alarm 1 from the security terminal TT „, the security alarm center TAC is configured to send a request for security alarm guard 2 to a yard-giving unit. This can be done purely automatically or by one or more human operators located at the security alarm center TAC, using a computer program that crosses on. the security alarm control panel server TAC-S and reference data stored in the security alarm control panel database, TAC-DB.

The security alarm center TAC sends the request for security alarm guard 2 over a communication channel 104 to the care unit. The communication channel 104 may typically include a fixed telecommunications network (PSTN), a mobile telecommunications network or global data network (WAN), or combinations thereof. The care unit will usually be a Care Giver Center (CGC), which 2,538,042 normally provides scheduled care services to the CT patient. By issuing a request for security alarm guard 2 to the care center CGC, the security alarm center TAC thereby urges the care center CGC to take care of the abnormal (ie not scheduled) alarm situation at the care recipient's home CTR „and the center CGC confirms.

The call center CGC therefore usually sends a confirmation of the request for security alarm gate 3 back to the security alarm center TAC upon receipt of the request for security alarm gate 2. This can cause the security alarm center TAC to move the alarm action from a "red card". "status (an appropriate action has been requested). However, the TAC security alarm center must continue to monitor how the alarm trade develops, as it does not yet have any knowledge of whether the alarm trade has actually been taken care of.

The call center CGC may have a call center server CGC-S and a call center database CGC-DB to allow automatic or operator-controlled assignment of an actual person to be instructed to handle the alarm operation, and, finally, the CT receiver, in the CTR. This actual person can often be a person in a team of CGP care staff who are on duty at the CGC care center. Such a person is designated by CGP, in Fig. 1.

The assigned, caregiver, the caregiver CGP, is then expected to move, as shown at 120, to the caretaker's home CTR "usually enter it through an exterior door 50" and of course take care of the alarm act (caretaker CT) as a gay origin of the security alarm 1. The custodian CGP, is expected to report back to the custodian unit that sent him out (ie the custodian center CGC in Fig. 1). The host, CGP, thus sends a report on challenge security alarm guard 4 over a communication channel 106, which may usually include a fixed telecommunications network (PSTN), a mobile telecommunications network or a global data network (WAN), or combinations thereof. This can be done orally as a telephone report over a conventional telephone call (for example via the security terminal TT, or a mobile telephone carried by the caregiver CGP). Alternatively, it can be done electronically by executing a certain reporting function in a computer program that is crossed by a barbaric computer terminal or intelligent telephone ("Smart Phone") carried by the caregiver CGP "or installed in the caretaker's home CTR ,.

Upon receipt of the report on security alarm alarm guard 4, the advisory unit (ie the call center CGC in Fig. 1) will usually generate a confirmation of challenge security alarm guard 5 and send it to security alarm center TAC over a communication channel, such as channel 104 in Fig. 1 or a separate channel. Upon receipt of the acknowledgment on challenge security alarm gate 5, the security alarm center TAC can move the alarm action from a "yellow coded" status to a "green coded" status, which represents that the handling has been completed by the alarm action relating to the security alarm 1 from the security alarm center TAC.

Prior art security alarm systems, including the security alarm system 10 of Fig. 1 as described above, have a number of shortcomings and disadvantages.

One problem lies in the legal degree of trust, or trust, that the security alarm center TAC can have in the response information received from or about the caring unit, and how this is correlated with the steering wheel's person actually behaving at the steering wheel's home. It should be noted that the confirmation of the request for security alarm guard 3 from the call center CGC only confirms to the security alarm center TAC that the request for security alarm guard 2 has been duly received; it says nothing about the fact that the alarm act in question is actually taken care of.

The fact that the caregiver CGP, himself, generates the report on challenge security alarm guard 4 further has its drawbacks. First of all, the security alarm center TAC (nor the security center CGC) can not know where the yard-giving person CGP is, in fact, covered when he generates the report. There is a risk that the caregiver CGP, generates the report too quickly, ie on road 120 to the caregiver's home CTRL, before arriving there. If the caregiver CGP does not actually appear at the caretaker's home CTR „then the security alarm center TAC will reset the alarm situation based on the misconception that the alarm act has been taken care of, even though this is not actually the case. As a result, the guard CT will be let down and paralyzed at his ode without care, which of course can be potentially very dangerous.

And, the life of the caregiver CGP, actually appears at the caretaker's home CTR, and generates the report on security alarm guard 4 when he is in front of damn 50, this does not necessarily mean that he will be able to gain access to the caretaker's home CTR „ ie he has the straight key to the door 50 ,? The situation is further complicated by the fact that in certain situations and for some CT receptionists, the care unit that received the request for security alarm guard 2 must call an alternative care unit to take care of the alarm situation. Such an alternative guarding unit may be, for example, a security service or an emergency service, which are not shown in Fig. 1 but are indicated on other drawings as SG ("Security Guard") and ES ("Emergency Service"), respectively. This may, for example, be the case when the nature of the alarm action is such that special resources are required, such as a reported burglary attempt, a suspected fire accident or a sudden threat of sudden illness in the guard CT.

A similar situation exists with certain types of caregivers CT who do not need regular, scheduled care of the caregiver center CGC but still have some reduction that justifies the existence of a safety terminal TT of safety shells, in case a temporary abnormal situation should arise in the caretaker's home CTRi. In such a case, the security guard CT may not even be a known user of the security center CGC, and the security alarm center TAC must send a request for security alarm guard 2 directly to the alternative security unit without involving the security center CGC. Alternative care units SG, ES usually have thousands of potential CT patients. It is not only uncertain whether they have a copy of the steering wheel key to the caretaker's home CTRi, but also it is at best uncertain whether they are familiar with the correct way to report back to the security alarm center TAC when the alarm transaction is handled. The problem from the security alarm center's TAC perspective, to obtain an effective and reliable monitoring that a security alarm transaction is handled, thus becomes weaker. In the case of security alarms, there is generally expressed room for improvement when it is necessary to report or monitor that a caregiver has acted at a caretaker's home for the purpose of handling an alarm transaction at the caretaker's home.

Detailed Description of Embodiments Fig. 2, which is a schematic view of a security alarm system 100 illustrating the present invention in general terms, will now be described.

Male reference numerals which are the same as in the prior art security alarm system 10 of Fig. 1 represent the same or functionally equivalent elements as those of Fig. 1; description of such elements has therefore already been given in the background section and will not be repeated in detail in the current section of clarity shell. The following brief description is considered fully sufficient.

The security alarm system 100 according to Fig. 2 comprises a security alarm center TAC and a plurality of security terminals TT for the use of the respective guard CT yid their respective yardkeeper dwellings CTR. Each security terminal, TT, is configured to send a security alarm 1 to the security alarm center upon the occurrence of an alarm transaction at the caretaker's home CTR ,. 538 042 The alarm action at the guard's home CTR, may arise, for example, due to manual influence from the guard CT, of an alarm function at the security terminal TT ,. This may involve pressing an alarm button on the security terminal or an alarm button on a wristband, as described in the background section.

Alternatively, the alarm action at the caretaker's home CTR, may arise due to automatic detection by a sensor device of an abnormal condition for the caretaker. Such a sensor device may be, for example, an accelerometer-based or optical fall sensor which detects a fall accident for the guard, a motion sensor which detects a period of immobility for the guard, or an acoustic sensor which detects a call for help or a moan from the guard.

As a further alternative, the alarm action at the caretaker's home CTR may occur due to automatic detection by a sensor device of an abnormal sanding for the caretaker's home. Such a sensor device can be, for example, a sensor for smoke, fire or humidity, which detects a dangerous situation at the caretaker's home, or a burglar alarm sensor that detects a burglar alarm at the caretaker's home.

As already described in the background section, the security alarm center TAC is configured, as a result of having received the security alarm 1 from the security terminal TT ,, to send a request for security alarm guard to a care unit. The guarding unit is shown as a guarding center CGC in Fig. 2; however, it can be an alternative care unit such as a security guard service SG or an emergency service ES. As a result, as in Fig. 1, the guarding unit can issue a confirmation on the request for security alarm emergency 2 to the security alarm center TAC. The security alarm center TAC is configured to monitor the receipt of a confirmation on challenge security alarm margin 5, which confirmation indicates that a caregiver CGPi (or alternative SG or ES) has acted at the caretaker's home CTRL in order to handle the alarm transaction.

The new and inventive features of the security alarm system 100 according to Fig. 2 over the previously known security alarm system 10 according to Fig. 1 will now be described.

For each of the care homes CTR, an electronic locking device LD is provided, for mounting on a device. 50, to the employee's home CTR ,. The electronic laser device LD, for which possible but non-limiting embodiments will be described in more detail later with reference to, for example, Fig. 5, comprises a sand taker (Figs. 5, 540) having the shape of a wireless interaction 4a with a key device KDk. Possible but non-limiting embodiments of the key device KDk will be described in more detail later with reference to, for example, Fig. 4.

The electronic welding device LD, also comprises an electrically controlled welding actuator (Figs. 5, 512) which is configured to actuate a welding mechanism (Figs. 5, 52) of a welding (Figs. 5, 54) for the door SO1.

The electronic laser device LD, further comprises a processing unit (Figs. 5, 510) which is connected to the receiver and is configured to cause the laser actuator to actuate the laser mechanism of the laser as a result of the wireless operation of the key device KDk. The processing unit is further configured to cause 4b to generate the acknowledgment on the challenge security alarm gate 5, to be received by the security alarm center TAC. As shown schematically at 130 in Fig. 2, this may occur in cooperation with other elements of the security alarm system 100. Possible but non-limiting embodiments in this respect will be described later with reference to Figs. 3a-3c.

From a functional perspective and as also illustrated in Fig. 7, the security alarm center TAC thus works in the following way to monitor the handling of a security alarm operation in the security alarm system 100: First, in a step 710, the security alarm center TAC receives a security alarm alarm 1, which is the beldgen at a caretaker's home CTR ,. Then, in a step 720, the security alarm center TAC sends a request for security alarm gate 2 to a care unit CGC, SG or ES, to initiate a security alarm guard which involves handling an alarm action at the yardkeeper's residence CTR ,.

Furthermore, in a step 730, the security alarm center TAC monitors receipt of a confirmation of challenge security alarm measure 5, which confirmation indicates that a yard-giving person CGTJ, SG or ES has acted at the caretaker's home in order to handle the alarm act, caused 4b by an electronic locking device LD, which is mounted on a door 50, to the caretaker's home and which is configured to actuate a locking mechanism 52 of a lock 54 on the door as a result of wireless interaction 4a with a key device KD ,. The provision of an electronic laser unit LD "which interacts wirelessly with a key device 1 (131 and which serves to cause 4b generation of the power on challenge security alarm guard 5 in the security alarm system 100) will solve or at least reduce the problems discussed above with respect to the former can 12 538 042 security alarm system 10. Della will become more apparent from the remainder of this detailed description, in particular with reference to Figs. 3a-3c.

However, Fig. 4 is a schematic block diagram of an exemplary key device KD which may interact with an electronic locking device LD in the security alarm system 100 shown in the other drawings. In the example shown in Fig. 4, the key device KD is a mobile terminal, for example a mobile telephone, personal digital assistant (PDA), intelligent telephone, tablet, etc., which can communicate with a telecommunication system. The caregiver CGPi, SG or ES can thus use the key device KD for various telecommunications services, such as rust calls, internet surfing, video calls, data calls, fax transmissions, still image transmissions, video transmissions, electronic messaging and e-commerce. These telecommunication services are generally not central in the context of the present invention; there are no restrictions on any particular set of services in this regard. Only components which are in any way relevant to the inventive functionality are thus shown in Fig. 4.

As shown in Fig. 4, the key device KD has a network interface 430 for connection to one or more communication interfaces. The network interface 430 may meet the commercially available standard for mobile telecommunications, including but not limited to GSM, UMTS, LTE, D-AMPS, CDMA2000, FOMA and TD-SCDMA. Alternatively or further, the network interface 430 may meet a standard for wireless data communication such as WLAN ("Wireless Local Area Nework") / WiFi. In an advantageous embodiment, the key device KD communicates with an access control system ACS shown in Fig. 3a and which will be described in more detail with reference to Fig. 6.

The key device KD also has a user interface 420, which may include a display 422 and a set of keys 424 or any other input device, as well as other known user interface elements such as a speaker and a microphone. The host GGPi, SG or ES can control the use of, and the data exchange with, the key device KD Over the user interface 420.

The key device KD further comprises a wireless sand receiver 440 for gear action 4a (and, if applicable, 4b, Fig. 3a; 4b ', Fig. 3b) with the electronic welding device LD. In an advantageous embodiment, the wireless sand receiver 440 provides wireless short distance data communication such as, for example, Bluetooth0, WLAN / WiFi, NFC ("Near Field Communication"), RF-ID ("Radio Frequency Identification") or IrDA ("Infrared Data Association"). ). 13 538 042 A processing unit 410 is overall responsible for the use and control of the various components of the key device KD. The processing unit 410 may be implemented with advanced controller technology, including not limited to a processor (PLC, CPU, DSP), FPGA, ASIC or any other suitable digital and / or analog circuitry which may perform the intended functionality.

The key device KD finally has a memory 450 which is operatively connected to the processing unit 410. The memory 450 can be implemented with any known memory technology, including not limited to E (E) PROM, S (D) RAM and flash memory, and it may also include secondary storage media such as a magnetic or optical disc. The memory 450 may physically consist of a unit or a plurality of units which together constitute the memory 450 at a logical level. In some embodiments it may be implemented at least in part as a storage area in another component of the key device KD, such as the processing unit 410 and / or the wireless sand receiver 440.

In addition to storing various program instructions and data for the various functions and applications commonly available in a mobile terminal, the memory 450 may also include computer program instructions 452 for an access control application used by the custodian when seeking access to the custodian's home CTR, by maneuver the laser on the 50, through the electronic laser device LD.

The memory 450 may also include stored access control data 470 to be transmitted to the electronic laser device LD when access is sought to the guard's home CTRL. Alternatively or in addition, the access control data 470 'may be entered by the caregiver via the user interface 420 on the key device KD, air transfer to the electronic reading unit LD when access is seen to the caretaker's home CTRL. Alternatively or additionally, the access control data 470 "may be retrieved by the key device KD from a remote server (such as, for example, an access control server ACS_S shown in Fig. 6) before or during the access attempt to the yardkeeper's home CTR ,.

Other types of key devices other than mobile terminals may operate with the security alarm system 100, including but not limited to RF ID tags or NFC active devices.

Fig. 5 is a schematic block diagram of an electronic laser device LD according to an embodiment of the present invention, which is adapted for use in the security alarm system 100 shown in the other drawings. The electronic locking device LD 14 538 042 is adapted to be mounted on a device 50 for a caretaker's home CTR, and has more specifically been assigned the task of causing the action of a locking mechanism 52 of a lock 54 on the door to the caretaker's home (CTR) by means of an electrically controlled welding actuator 512, to allow the door 50 to be opened. "Causing the action of a laser mechanism on a laser" is thus, in the present document, to be construed as including the activity of directly or indirectly influencing a part, an organ, an element, a module or the like of the laser mechanism, so that the laser alternates from a laser. first state in which unloading of the laser is prevented to a second state in which unloading of the laser is no longer prevented.

Referring to Fig. 5, the welding device LD generally comprises the following main components. A processing unit 510 is overall responsible for the use and control of the various components of the lead device LD. The processing unit 510 may be implemented in phage known controller technology, including but not limited to a processor (PLC, CPU, DSP), FPGA, ASIC or any other suitable digital and / or analog circuitry which may perform the intended functionality.

The processing unit 510 is operatively connected to the welding actuator 512 to cause the actuation of the welding mechanism 52 upon successful verification of the key device's KD authority to unlock the lock 54 (ie to gain access to the guard's home CTR).

The welding device LD in the illustrated embodiment is an independent, autonomously operating device which does not require any wiring, either for communication or for power supply. Instead, the laser device LD is powered by a local battery power supply unit 520 which includes one or more long life batteries. It interacts with key devices KD, already mentioned, through wireless activities. The welding device 40 thus has a wireless sand receiver 540 for the interaction 4a (and, when applicable, 4b, Fig. 3a; 4b ', Fig. 3b) with the key device KD. In an advantageous embodiment, the wireless sand receiver 540 is capable of wireless short-distance data communication such as, for example, Bluetooth0, WLAN / WiFi, NFC, RF-ID or IrDA.

The locking device LD in the embodiment shown further comprises a real-time clock 530 capable of providing the processing unit 510 with a correct value of the current time. However, embodiments are also possible where no real-time clock is provided. 538 042 The laser device LD finally has a memory 550 which is operatively connected to the processing unit 510. The memory 550 can be implemented with advanced memory technology, including but not limited to E (E) PROM, S (D) RAM and flash memory, and it may also include secondary storage media such as a magnetic or optical disc.

The memory can physically consist of one unit or several units which together make up the memory 550 at a logical level. In some embodiments, it may be implemented at least in part as a storage area in another component of the welding device LD, such as the processing unit 510 and / or the wireless sand receiver 540.

The purpose of the memory 550 is to store various computer program instructions and work data for functions to be performed by the processing unit 510 in order to perform the tasks of the laser device LD. These program instructions define, for example, a main access control module 552 which is responsible for the general parts of the functionality on the loader side as it interacts with the KD in order to potentially upset the load on the door 50. A communication module 560 will handle the actual communication with the key device KD in cooperation with the wireless sand receiver 540. There may also be an encryption / decryption module for things communication to and from the laser device LD, where such encryption / decryption can for example be based on AES ("Advanced Encryption Standard").

The memory 550 further has the task of storing access control data 570 which is to be used to decide whether or not the KD seeking access to the caretaker's residence CTRL is to be given access or not. In one embodiment, such stored access control data 570 may be in a local database LD DB stored in memory 550.

The processing unit 510 in the laser device LD is advantageously configured to cause generation of the confirmation on the challenge security alarm gate 5 only when the key device KD has been verified to have the authority to actuate the welding mechanism 52 of the laser 54 for the device on which the laser device LD is mounted. This represents an improvement over the previously known security alarm system 10 according to Fig. 1, in that it has now been ensured that the confirmation of the challenge security alarm guard 5 will only be generated if the key device KD has been shown to be allowed to come to the caretaker's home CTR and has actually caused unloading the lock 54 on the door 50.

The processing unit 510 in the locking device LD is thus configured to verify the authority of the key device KD by analyzing the fulfillment of the access control data 470, 470 ', 470 "received from the key device KD 16 538 042 during the wireless interaction 4a, with respect to the access control data 570. stored in the laser device LD.

In one or more embodiments, this analysis may involve checking an identity 470 of the key device KD against a pre-stored permitted key device identity 570 or a list of permitted key device identities in the LD_DB. Such a key device identity can, for example, be represented by a Bluetooth0 ID, a MAC address, an IP address, a WiFi address, a serial number, and combinations & ray.

In one or more embodiments, this analysis may include checking user data 470 ', which has been entered on the key device by the host CGPi, SG or ES, against the corresponding reference data 570 in the electronic reading device LD. Such user data may, for example, refer to a password or a PIN code, a fingerprint image, a face recognition image, a retina scan image, and so on.

In one or more embodiments, this analysis may involve validating a received digital certificate or signature 470 using asymmetric cryptographic principles.

In one or more embodiments, this analysis may involve checking a received shared secret 470 against a stored copy 570 of the stored secret. Combinations of these exemplified alternatives are also. possible; In other words, the device LD can verify the authority of the key device KD by two or more tests or analyzes in combination.

As soon as the key device KD has been successfully verified as appropriate, the processing unit 510 will control the welding actuator 512 to cause the welding mechanism 52 of the lock 54 to be actuated. In addition, the processing unit 510 will also cause generation of the confirmation on challenge security alarm gate 5 already.

For further possible implementation details and possible additional components in the welding device LD, reference is made, for example, to WO 2006/098690, WO 2008 / - 101930 and WO 2011/065892, which are incorporated in their entirety here by reference.

Reference is now made back to the processing unit 510 in the electronic unit LD „and more specifically how it can be configured to cause 4b generation of the confirmation on challenge security alarm gate 5, is received by the security alarm center TAC, which was only indicated at a clear level. at 130 in Fig. 2. Possible but non-limiting embodiments in this respect will thus now be described with reference to Figs. 3a-3c. Reference numerals which are the same in any of Figs. 3a-3 538 042 3c which in any of the preceding drawings represent the same or functionally equivalent elements as those which appear in the preceding drawings.

In Fig. 3a, or more precisely in an embodiment thereof, the processing unit 510 in the laser unit LD, may be configured to cause 4b to generate the power on the challenge security alarm gate 5 by generating the power on the challenge security alarm gate 5 locally in the laser device LD, and send it to the key device KDk, for further transmission to the security alarm center TAC, which is seen at 4c, via the network interface 430.

Thus, in this embodiment, the locking device itself creates the acknowledgment on the challenge security alarm gate 5 and uses the key device as a courier or relastation to send the acknowledgment on the challenge security alarm gate 5 to or against the security alarm center TAC. In one embodiment, where the security alarm system 100 also includes an ACS access control system (which will be described in more detail below with reference to Fig. 6), the generated confirmation on challenge security alarm gate 5 of the key device KDk is transmitted through the ACS access control system to the security alarm system. In another embodiment, the generated confirmation on challenge security alarm gate 5 is sent by the key device KDk to the security alarm center TAC through a communication channel such as a fixed telephony (PSTN), a mobile telecommunications or global data network (WAN), or combinations thereof. In a further alternative embodiment, the generated confirmation of the challenge security alarm gate 5 can be sent by the key device KDk to the security alarm center TAC through the sensing center CGC.

In yet another embodiment, the processing unit 510 of the laser device LD is configured to cause 4b 'to generate the power on the challenge security alarm gate 5 by instructing or allowing the key device KDk as soon as it is verified to have the authority to actuate the laser mechanism 52 of the laser 54 for the device 50, on which the locking device LD is mounted, to generate the acknowledgment on the challenge security alarm gate 5 and send it to or against the security alarm center TAC.

Thus, in this embodiment, the locking device itself does not create the confirmation on challenge security alarm guard 5 but commands the key device to generate the acknowledgment on challenge security alarm guard 5 and send it to or against the security alarm center TAC - thereby in practice causing, or initiating, the challenge of generating the challenge. in this embodiment, the generated acknowledgment on challenge security alarm gate 5 can be sent by the key device KDk through the access control system ACS according to Fig. 6 to the security alarm center TAC, or alternatively to the security alarm center TAC through a communication channel such as a fixed telecommunication or fixed telecommunication (WAN), or combinations thereof.

In yet another embodiment, the processing unit 510 of the device LD is configured to cause 4b to generate the acknowledgment on the challenge security alarm gate 5 by informing the key device KDk that it has been verified to have the authority to actuate the locking mechanism 52 of the lock 50 for the Ma 50 on which the locking device LD, is mounted, the key device KDk reporting this to the access control system ACS, and wherein the access control system ACS is configured to generate the acknowledgment on challenge security alarm gate 5 and send its nurse to the security alarm center TAC.

Fig. 6 illustrates, in a clear and simplified form, the arrangement for an embodiment of the ACS access control system referred to in Fig. 3a, as well as the typical caretaker environment in which it operates. A first team of caretaker staff CGP is responsible for the care of a first group of caretakers (cf. CT in the previous description), who all live in the respective caretaker's dwellings (cf. CTR in the previous description) which are protected by the respective exterior doors 1-50 „. Electronic locking devices LD, -LD „are installed on the respective outer doors 501- and act as intradesports to the respective protected million (i.e. the yard-20 taker's home) behind each device. A first set of key devices KD, - is available for the first team of caregivers CGP. The key devices KDi-KDrn can be, for example, mobile terminals. Each locking device LD, -LD „contains some kind of access control data (cf. 570 in Fig. 5), which can be used to evaluate whether or not a key device in question should be given access to the caretaker's home.

When a guardian from the first team starts sift work shift, he can receive one of the key devices KDi-KD „, from a call center (cf. CGC in the previous description), for example key device KB ,. During the work shift, he can use the key device KD, to gain access to various doors among the outer doors 501-50 „to provide the care and care required by the respective caretakers (provided that his key device KD, is authorized). This access will be provided through wireless communication between key device and locking device, as previously described. At the end of the work shift, the caregiver can re-acknowledge and return the key device KD to the call center. In addition or alternatively, some or all of the members of the first team of caretaker staff CGP may use their own mobile terminals as key devices. Not all key devices or members of the first team of CGP caregivers need to be eligible to attend all Marks, and they do not all need to have the same level of eligibility for certain times and / or dates during which access is allowed.

As shown in Fig. 6, the guarding million further includes a second team of guarding staff CGP's responsible for serving a second group of guards, whose guarding houses have respective exterior doors 501-50 ', on which electronic lasers are installed. A second set of key devices K131, -KDm, is available for the second team of caretaker staff CGP '. The millionaire guardian can of course in reality include additional teams of guardian staff, additional groups of guardians, additional exterior doors, additional locking devices and additional sets of key devices.

Alternative care units can also be included in the care million, in the form of a security guard service SG or an emergency service ES with key devices KDsg and KDes. While the key devices KDi-KDrn, KDF-KDm, for the first and second teams CGP, CGP 'will be used by a relatively large number of caregivers to access a relatively small number of loaders / doors relatively often, the situation may be the opposite for the key devices. I (Dsg and I (Des for the security guard service SG or the emergency service ES). These key devices will be used by a limited number of people (such as paramedics, nurses or guards) in rare cases, but nevertheless they must be able to access a very large number of laser devices. / dorrar - or even all laser devices / dOrrar that are part of the changing million.

For improved security, each key device can have an access control software application that the user must log in to. All communication with the locking devices can further be encrypted.

Each team of caregiver staff CGP, CGP 'can be further divided into subgroups, such as a day shift, an evening shift and a night shift. An individual caregiver may further act in or may be behind the teams CGP and CGP '(for example to act as reserves in case of illness, parental leave or during popular holiday periods), whereby he has a need to use his key device to access lasers. in the first group of caretakers as in the second group of caretakers. This is illustrated in Fig. 6 for the key device KDm, which 538 042 will be not only the laser device LD, in the first group of guards, but the laser device LDi, in the second group of guards.

The purpose of the access control system ACS is to control the access to the plurality of laser devices LD1, -LD ,, for a plurality of users CGP, CGP ', SG, ES with a plurality of key devices KDiKDm, KDF-KD „,,, KD, g, KDes. The access control system includes dad & an access control system server ACS _S and an access control system database ACS DB. The key devices can communicate (via the network interface 430) with the access control system server ACS _S via the network interface 430 over a local network (WLAN / WiFi) 620 and / or a global network (eg Internet) or mobile network 630.

The ACS_DB access control system database is configured to contain cross-reference or mapping data 610 which defines the access properties of the respective key devices among the key devices and the corresponding users among the users of the respective laser device among the laser devices. Fig. 6 contains an enlarged representation of this cross-reference or mapping data 610. As shown at 612 and 613, a receiver CT is mapped to a laser device LD (or several devices, or vice versa). Similarly, as shown at 614 and 615, a guarding person CGP is mapped to a key device KD (or several key devices, or vice versa). Similarly, a security guard or emergency service officer SG or ES is mapped, at 616, to a key device KD (or several key devices, or vice versa). Finally, said reference or mapping data 610 contains associations which connect allowed key devices KD with certain read devices LD.

In embodiments where the laser devices LD include a local database LD_DB, this may be configured to store a replicated version, or a subset thereof, of the contents of the access control system database ACS_DB. The processing unit 510 in an individual locking device LD, may be configured to verify the authorization of a key device KDk seeking access by determining an identity of the key device under wireless interaction 4a and by checking the authorization of the key device identified in this manner by cross-reference. local database LD_DB. This allows a high degree of security in the system and still allows the laser devices LD to function as autonomous units. Entry and updating of replicated ACS DB data to LD_DB can be done via the wireless sand receiver 540, and the key devices can act as couriers for this information during certain security arrangements. As already mentioned, the key device identity, 21 538 042 for example, can be represented by a Bluetooth0 ID, a MAC address, an IP address, a WiFi address, a serial number and combinations thereof.

As described above, the ACS access control system may be involved in the generation and / or forwarding of the generated acknowledgment on challenge security alarm gate 5 to the security alarm center TAC.

It is advantageous to use the ACS access control system to pass on a confirmation of the challenge security alarm gate 5 generated either by the device LD, or by the key device KDk, as this makes it possible to add additional information to the security alarm center TAC. For example, it may be that the key device KDk only knows its key device identity 615 but not the identity of the custodian CGPJ using it. The ACS access control system will, however, have access to the said mapping data 610 in the ACS_DB access control system database and can thus determine the identity 614 of the host CGPJ, and add this information to the acknowledgment on challenge security alarm gate 5 sent to the security alarm center TAC.

The same applies to the identity 613 for the laser device LD, compared with the identity 612 for the guard CT ,.

It is advantageous to use the ACS access control system to generate the acknowledgment on challenge security alarm gate 5, as this improves the reliability of the acknowledgment on challenge security alarm gate 5 from the security alarm center's TAC point of view. One can imagine a situation where the locking device LD, made its decision to allow the key device KDk to access the receiver's home CTR, based on an output replicated version (or subset dray) of the contents of the access control system database ACS DB, and as a result granted access for the key device KDk alien even though its access rights had later been originated or changed in the ACS DB access control system database. The ACS access control system can detect this discrepancy and either refrain from sending a confirmation of the completed security alarm gate 5 to the security alarm center TAC or, even better, send a call to the security alarm center TAC, so that the latter has a chance to correct another person by mistake. CGP or maybe a security guard SG.

Reference is now made again to the processing unit 510 in the electronic device LD „and more specifically how this can be configured to cause generation of the confirmation on challenge security alarm gate 5, which is to be received by the security alarm center TAC. Some possible but non-limiting embodiments 22 538 042 were described with reference to Fig. 3a. Additional alternatives will now be described with reference to Figs. 3b and 3c.

In Fig. 3b, the processing unit 510 of the locking device LD is configured to cause 4b 'generation of the force on the challenge security alarm gate 5 by instructing or allowing the key device KDk, as soon as it is verified to have the authority to actuate the locking mechanism 52 of the lock 54 for the door 50 , on which the laser device LD, is mounted, to generate a report on challenge security alarm guard 4c to be sent to the sensing center CGC. The call center CGC is configured, as a result of receiving the report on challenge security alarm gate 4c, to generate the confirmation of challenge security alarm gate 5 and send it to the security alarm center TAC.

In Fig. 3c, the processing unit 510 of the laser device LD is configured to cause 4b "generation of the power on the challenge security alarm gate 5 by generating the power on the challenge security alarm gate 5 locally in the laser device and sending it to the security terminal TT, for transmission to the security center. 102. Alternatively, the processing unit 510 of the device LD may instruct or allow the security terminal TT to generate the acknowledgment on the challenge security alarm gate 5 and send it to the security alarm center TAC.

This alternative embodiment has the advantage that it uses a reasonably priced unit in the security alarm system 100, namely the security terminal TT „for the transmission of the confirmation on challenge security alarm guard 5. Another advantage is that no special construction is required for the key device KD; it is sufficient if it is a simple RF ID or NFC tag, which is more likely to be carried by alternative yard-giving devices such as security guards or emergency services.

In a refinement of this alternative embodiment, the processing unit 510 of the laser device LD is further configured to include, in or with the generated acknowledgment on the performed security alarm gate 5, information about a remaining charge level of the battery power supply unit 520 in the laser device LD 1. This represents a resource-efficient way of communicating this information, which can be critical in terms of operational reliability, to the security alarm center TAC through the security terminal TT ,.

The present invention has been described with reference to a number of exemplary embodiments. However, modifications of these embodiments, as well as other embodiments, may be possible within the scope of the claims, as will be readily apparent to one skilled in the art. Although the TAC security alarm center and the CGC care center 23 538 042 have been described as separate units in this specification, they can be integrated into a structural unit in alternative embodiments, for example. Similarly, the ACS access control center can be structurally integrated with the TAC security alarm center or the CGC security center. 24
