ATTENDANCE MONITORING PROCEDURES AND MONITORING SYSTEM

Description

Field of invention

[0001] The present invention relates to a building surveillance system and a method for monitoring presence in a surveillance area of the building. Prior art

[0002] It is common to have an alarm system that can detect malicious activity in a building. However, implementing such a system can be complex because sensors and a monitoring center need to be positioned and configured.

[0003] Such an alarm system can also be complicated to manage on a daily basis, because people authorized to enter the building are indiscriminately detected by the alarm system and must then proceed to neutralize the alarm system.

[0004] Document US 2012 / 092502 A1 describes a surveillance system that includes a motion detector that provides detection information to a surveillance application.

[0005] WO 2015 / 130744 A1 describes a system and method combining motion detection data with presence detection data to determine an intrusion / alert.

[0006] The present invention, defined by the appended claims, aims to resolve all or part of the drawbacks mentioned above. Statement of the invention

[0007] To this end, the present invention relates to a method for monitoring presence in a surveillance zone by a surveillance system as described in claim 1.

[0008] This arrangement makes it possible to take advantage of the extent of a previously existing network, namely the communication network, for detecting the presence or absence of a terminal in the surveillance zone.

[0009] This internal building communication network is therefore used by the system to detect the presence of a terminal in the surveillance zone. An intrusion can therefore be detected by the surveillance system when there is no correspondence between a motion detection and a terminal detection. In this case, the surveillance system is able to determine whether there is a risk of intrusion in the surveillance zone.

[0010] Alternatively, the presence of a terminal in the surveillance area may be indicative that an expected person is in the surveillance area. This may help reassure users that an expected person is present.

[0011] The listening module or the monitoring device may, depending on the embodiment variants, communicate movement information or presence information to the processing unit via the router or via another connection.

[0012] It is also possible to check whether a new terminal can be detected in the communication network after motion detection. For example, if the detection zone is located near an access door to the monitoring area, it is possible to detect whether a person entering is a known person.

[0013] According to one aspect of the invention, the processing unit is arranged to connect to the communication network.

[0014] This arrangement allows for a processing unit to be present in the monitoring area.

[0015] Preferably, the processing unit is included in a separate device present in the monitoring area or is included in a terminal capable of connecting to the communication network.

[0016] Thus, it is not necessary for the router to be connected to another communication network external to the monitoring area to implement the method.

[0017] According to another aspect of the invention, the processing unit is included in a server external to the communication network and the router is able to connect to the server.

[0018] This arrangement allows the use of a remote server, for example a server existing prior to the establishment of the surveillance zone, for the interpretation of presence information and / or movement information.

[0019] The processing unit can be physically located in the monitoring area or located at the external server linked to the router or located at a terminal.

[0020] According to one aspect of the invention, the monitoring device and / or the listening module are arranged to be connected to the communication network.

[0021] Thus the exchange between the processing unit on the one hand and the monitoring device and / or the listening module on the other hand can be carried out directly in the communication network or via the router when the processing unit is included in the server.

[0022] According to another aspect of the invention, the listening module is included in the router.

[0023] This arrangement facilitates the detection carried out by the listening module in the data packets exchanged in the communication network and received by the router. In fact, the exchanged data packets are directly available to the listening module.

[0024] According to one aspect of the invention, the presence control method further comprises the following steps carried out by the processing unit: receiving presence information and / or movement information, applying an association function to the presence information and / or movement information, the application of the association function generating correspondence information, analyzing the correspondence information according to at least one irregularity determination criterion.

[0025] This arrangement allows information relating to detected movements and terminals detected in the surveillance area to be concentrated at the processing unit level.

[0026] The process therefore makes it possible to determine whether a movement is suspicious because there is no terminal in the surveillance zone or if the number of movements detected is significant compared to the number of terminals detected, an irregularity may be observed. Depending on the type of irregularity, an alarm may be triggered or a user warned.

[0027] According to one aspect of the invention, the association function consists of establishing that a detected movement either corresponds or does not correspond to the presence of a determined terminal detected in the communication network.

[0028] This provision makes it possible to detect which movements are not generated by a user with a specific terminal.

[0029] According to one aspect of the invention, the association function also consists of establishing either a correspondence or a non-correspondence between a user profile previously referenced in connection with a terminal and a terminal whose presence is detected.

[0030] This makes it possible to determine which user is present in the surveillance zone or if a terminal not previously referenced in connection with a user profile is detected.

[0031] According to one aspect of the invention, an irregularity determination criterion corresponds to a detected movement not linked to a user profile. This movement is therefore potentially an intrusion.

[0032] According to one aspect of the invention, another irregularity criterion corresponds to a detection of a terminal of a user whose profile is known while no corresponding movement has been detected for a determined duration.

[0033] An alert can thus be issued if a terminal is detected in the surveillance zone without this corresponding to a movement detection in the surveillance zone for a specific period of time. The user in question may have become unwell and be unable to leave the surveillance zone.

[0034] According to one aspect of the invention, the presence control method further comprises a step of recording the presence information and / or the movement information in the memory of the processing unit.

[0035] This arrangement allows the processing unit to build a history of movement information and presence information from the monitoring device.

[0036] According to one aspect of the invention, the movement information is time-stamped by the monitoring device and / or the presence information is time-stamped by the listening module.

[0037] This provision facilitates the application of the association function and the analysis of the correspondence information according to an irregularity determination criterion.

[0038] According to one aspect of the invention, when the presence control method as described above is executed several times, the steps of applying the association function and analyzing the correspondence information also take into account the presence information and / or movement information previously recorded in the memory of the processing unit, in particular when this presence information and / or movement information is determined in the same time window.

[0039] According to one aspect of the invention, the step of detecting at least one movement of at least one entity is followed by the step of detecting the absence and / or presence of at least one terminal in the communication network.

[0040] This arrangement makes it possible to check whether a new terminal can be detected in the communication network after motion detection. For example, if the detection zone is located near an access door to the surveillance area, it is possible to detect whether a person entering is a known person.

[0041] According to an aspect not forming part of the invention, the step of detecting the absence and / or presence of at least one terminal in the communication network is carried out repeatedly according to a determined frequency.

[0042] This arrangement makes it possible, on the one hand, to regularly send presence information to the processing unit and, on the other hand, to reduce the energy consumption of the monitoring device since the detection of an absence and / or presence of at least one terminal is not carried out on an ad hoc basis.

[0043] According to one aspect of the invention, the step of sending the presence information is carried out following the step of creating and / or modifying in memory of the monitoring device presence information or at the request of the processing unit or according to a defined time base.

[0044] This arrangement allows presence information to be sent to the processing unit either as quickly as possible or on a regular basis. Several operating modes can thus be distinguished.

[0045] A first operating mode called "alarm deactivated" which is not part of the invention, is defined by a quasi-permanent detection of movement, that is to say that the step of detecting movement is carried out by an active movement detector (periods of standby of the movement detector can alternate with periods in which it is active), and correspond to a periodic detection of presence information. The transmission to the electronic processing unit is also carried out on a periodic basis: this involves providing the processing unit with practical information on absences and presences in the surveillance zone.

[0046] In this case, the monitoring system works economically since the monitoring device only connects to the communication network occasionally at a specific frequency.

[0047] A second operating mode, called "alarm activated", is defined by quasi-permanent motion detection and presence detection carried out following the detection of motion. The motion information and presence information are then immediately transferred to the processing unit. This involves providing the processing unit with useful information on absences and presences in the surveillance zone, particularly for the purpose of intrusion detection.

[0048] In this case, as soon as a movement is detected, a check is carried out to verify the presence of the terminals in the surveillance zone and then this information is sent back to the processing unit. Thus, the step of detecting the absence and / or presence of at least one terminal in the communication network can take place with a higher frequency than in the “alarm deactivated” mode if numerous movements are detected.

[0049] Of course, other operating modes can be defined as variants of the two modes presented above, depending on the constraints of information upload speed and the limitation of the desired energy consumption of the monitoring device.

[0050] According to one aspect of the invention, the presence information further comprises an indication relating to the solicitation of the terminal. Preferably, the indication relating to the solicitation comprises an indicator of activity and / or movement of the terminal.

[0051] This provision allows any suspicious behavior to be reported to the processing unit, for example if a laptop has not been used for a long period. In this case, an irregularity may be noted: the user may have become unwell and be unable to use their terminal.

[0052] According to one aspect of the invention, the presence control method further comprises a step of sending return information by the processing unit to a receiving terminal corresponding to a user profile referenced as a receiver in the memory of the processing unit, the return information comprising an indication relating to the movement information and / or to the presence information and / or to a result of the analysis of the correspondence information according to the at least one irregularity determination criterion.

[0053] This provision allows any user whose profile is referenced as a receiver to have feedback information concerning the monitoring of the building.

[0054] This arrangement is useful because the user can be away from the processing unit or even outside the monitoring area and still be aware of detected movements, terminals present and / or possible irregularities or alarms relating to the monitoring area.

[0055] According to one aspect of the invention, the presence information corresponds to a terminal other than the receiving terminal. This arrangement is particularly useful for a user referenced as a receiver who wishes to know the situation of other users. These other users will in particular be referenced with a transmitter profile, that is to say, whose absence or presence can be determined and transmitted to the listening module.

[0056] According to one aspect of the invention, the presence control method further comprises a step of receiving command and / or control information by the processing unit from an administrator terminal corresponding to a user profile being referenced as administrator in the memory of the processing unit, the command and / or control information comprising: a request relating to the execution of a step of detecting an absence of movement or at least one movement of at least one entity and / or a step of detecting an absence and / or a presence of at least one terminal in a communication network, and / or, a request relating to the execution of a step of applying the association function and / or to the execution of a step of analyzing the correspondence information, and / or, a request relating to the execution of a step of sending by the processing unit of return information.

[0057] Thus, a user having a profile referenced in the processing unit as an administrator is able to remotely control the progress of the steps of the presence control process, in particular by defining the detection rates and receiving feedback information more or less frequently if this user is also referenced as a receiver.

[0058] This user can thus be warned of detected irregularities which may be alarms. He can thus remotely react to these irregularities by indicating to the processing unit that they are not to be considered as irregularities.

[0059] We can thus distinguish a terminal including a referenced transmitter profile as a "monitored" terminal and a terminal including a referenced administrator and / or receiver profile as a "monitoring" terminal. A non-referenced terminal can be considered as an indicator of intrusion.

[0060] According to one aspect of the invention, the return information and / or the command and / or control information passes via the router.

[0061] This arrangement allows a user with a terminal present in the surveillance zone to benefit from the communication network.

[0062] The present invention also relates to a monitoring system, arranged to implement the presence control method as described above, comprising: a monitoring device capable of exchanging information according to a communication protocol of the communication network, the monitoring device comprising a communication module arranged to exchange information according to the communication protocol and a motion detector provided with a sensor, the motion detector being configured to determine motion information relating to the detection of a movement of an entity in a detection zone of said sensor, a listening module arranged to communicate with a router and provided with a packet analyzer configured to extract from at least one data packet exchanged in the communication network and received from the router presence information relating to or an absence or a presence of at least one terminal in the communication network,a processing unit comprising a processor arranged to receive presence information from the listening module and movement information from the monitoring device.

[0063] According to one aspect of the invention, the processing unit is arranged to send a request to the listening module upon receipt of movement information, said request corresponding to a request to obtain presence information.

[0064] This provision makes it possible to check whether a terminal can be detected in the communication network after detecting movement. It is therefore possible to associate the detection of movement with the presence of a known person if the terminal in question is a known terminal.

[0065] According to one aspect of the invention, the sensor of the motion detector comprises an infrared detector and / or a camera.

[0066] According to one aspect of the invention, the listening module is arranged to exchange information with the processing unit. Preferably, the listening module is included in an alarm center which is arranged to manage a building alarm system.

[0067] This arrangement allows the use of an existing alarm system to detect presence information.

[0068] According to one aspect of the invention, the monitoring device comprises a detection system capable of detecting a malicious intrusion into the building.

[0069] Preferably, the detection system comprises a plurality of motion detectors. In particular, the detection system comprises a plurality of independent elements, each motion detector being included in a corresponding independent element and the independent modules being arranged to exchange information with a central entity of the detection system provided with a processor.

[0070] This arrangement allows movement to be detected throughout the building.

[0071] According to one aspect of the invention, the detection system is arranged to establish an independent wired and / or wireless network for the exchange of information between the independent elements and the central entity.

[0072] The detection system is thus independent of the communication network, which allows independent operation.

[0073] According to another aspect of the invention, the listening module is included in the monitoring device. This arrangement makes it possible to simply set up a monitoring system in the case where there is no listening module already installed in the building. Setting up a monitoring system is easy since it is sufficient to set up a monitoring device in the building equipped with an internet router.

[0074] According to one aspect of the invention, the processing unit is arranged to connect to the communication network.

[0075] This arrangement allows for a processing unit to be present in the monitoring area.

[0076] Preferably, the processing unit is included in a separate device present in the monitoring area or is included in a terminal capable of connecting to the communication network.

[0077] Thus, it is not necessary for the router to be connected to another communication network external to the monitoring area to implement the method.

[0078] According to another aspect of the invention, the processing unit is included in a server external to the communication network and the router is able to connect to the server.

[0079] This arrangement allows the use of a remote server, for example a server existing prior to the establishment of the surveillance zone, for the interpretation of presence information and / or movement information.

[0080] According to another aspect of the invention, the listening module is included in the router.

[0081] This arrangement facilitates the detection carried out by the listening module in the data packets exchanged in the communication network and received by the router. In fact, the exchanged data packets are directly available to the listening module.

[0082] The present invention further relates to a method of referencing by a monitoring system a family account in memory of a processing unit of the monitoring system comprising the following steps: creation and / or modification of a family account comprising at least one user profile in the memory of the processing unit, assignment to the at least one user account of a reference as administrator and / or receiver by the processing unit, an administrator being able to send command and / or control information to the processing unit, a receiver being able to receive return information from the processing unit, establishment of a local communication network by a monitoring device and / or a listening module of the monitoring system, reception via the local communication network by the monitoring device and / or the listening module of an access reference to a communication network of the monitoring system extended in a monitoring area to the monitoring device and / or the listening module,connecting the monitoring device and / or listening module to the wide area communication network using the access reference.

[0083] This arrangement makes it possible on the one hand to determine the authorizations of the different users and on the other hand to connect the surveillance device and / or the listening module to the surveillance system.

[0084] Thus, the communication network of the surveillance system can be a pre-existing network of a building. The surveillance zone then corresponds to the range of the building's communication network.

[0085] This arrangement therefore makes it possible to define an extended surveillance area without additional networking equipment. The local communication network of the surveillance device and / or listening module can therefore have a short range compared to the communication network of the surveillance area.

[0086] According to one aspect of the invention, the step of creating and / or modifying a family account and / or the step of assigning a reference is carried out by input at an interface of the processing unit.

[0087] According to one aspect of the invention, the interface of the processing unit is a remote interface. Preferably, the interface of the processing unit is provided in the terminal, the terminal and the processing unit being capable of exchanging information.

[0088] According to one aspect of the invention, the step of receiving an access reference is preceded by a step consisting of scanning a pattern such as a barcode with a terminal comprising a communication module capable of connecting to said local communication network and, the pattern corresponding to an identification of the monitoring device and / or the listening module.

[0089] This arrangement allows for rapid connection of the monitoring device and / or listening module to the communications network of the monitoring area.

[0090] The identification of the monitoring device and / or listening module acquired by the terminal equipped with a camera allows the transfer of this identification to the router and / or the processing unit which authorizes the connection by sending an access reference to the monitoring device and / or listening module.

[0091] It thus appears that the monitoring device and / or the listening module act as a router, in particular for the configuration and initial identification of the terminals.

[0092] Then, once the monitoring device and / or the listening module are part of the communication network, they are able to communicate with the processing unit according to the presence control method as described above.

[0093] According to one aspect of the invention, the communication network and / or the local communication network are WiFi type networks or using another technology, such as LoRa or Sigfox technology.

[0094] According to one aspect of the invention, the external communication network is an Internet or 3G type network or any other type of wide area network.

[0095] According to one aspect of the invention, the steps of the referencing method are steps prior to the steps of the presence control method as described above.

[0096] The different aspects defined above which are not incompatible may be combined. The invention is defined by the appended claims. Brief description of the figures

[0097] The invention will be better understood with the aid of the detailed description which is set out below with reference to the appended drawing in which: there figure 1is a schematic view of a building and a surveillance system; the figure 2 is a diagram representing a router of the surveillance system capable of putting an external communication network into communication with a communication network of the surveillance system; the figure 3 is a diagram representing the steps of a process for referencing a family account for use in the monitoring system; the figure 4 is a similar pattern to that of the figure 2 and further comprising a local communication network used for the referencing process; the Figure 5 is a diagram representing the steps of a presence control process by the monitoring system. Description with reference to figures

[0098] In the detailed description which follows of the figures defined above, the same elements or elements fulfilling identical functions may retain the same references so as to simplify the understanding of the invention. Surveillance system

[0099] As illustrated in the figure 1 , a surveillance system SY for a surveillance zone ZS of a building B comprises a surveillance device DI.

[0100] The DI monitoring device includes an MCDI communication module allowing it to exchange information according to a communication protocol of the SY monitoring system.

[0101] The DI monitoring device also includes a BA battery and a CA motion detector configured to determine IM motion information.

[0102] The AC motion detector comprises a sensor, for example provided with an infrared detector and / or a camera.

[0103] The movement information IM relates to a detection of an absence of movement or at least one movement of at least one entity E1, E2, En in a detection zone ZD of the surveillance zone SZ.

[0104] The monitoring system SY further comprises a listening module ME provided with a packet analyzer configured to extract IP presence information from a data packet exchanged in a communication network R1. The IP presence information relates to an absence or presence of at least one terminal T1, T2, T3, Tn in the communication network R1.

[0105] The monitoring system SY also comprises a processing unit UT. In the embodiment presented, the processing unit UT is included in a server SE. However, it can be physically included in the monitoring zone ZS, associated for example with the monitoring device DI or an alarm control panel box. It could also be located at a terminal T1, T2, T3, Tn or any other device capable of being connected to the communication network R1.

[0106] The SE server is remote and includes an MCSE communication module to enable connection of the UT processing unit to an external communication network R2, for example the Internet.

[0107] The processing unit UT is provided with a processor and is arranged to receive presence information IP from the listening module ME and movement information IM from the monitoring device DI.

[0108] As illustrated in the figure 2 , the monitoring system SY comprises a router RO capable of transmitting information between the communication network R1 and the external communication network R2. In particular, the router RO connects the monitoring system SY to the server SE, external to the communication network R1.

[0109] The ME listening module can be included in a CE alarm control panel box which is arranged to manage an alarm system of building B. In this case, it is possible to use the ME listening module of the alarm system previously installed in the building and to constitute a SY monitoring system by adding a DI monitoring device. Alternatively, the ME listening module can be included in a RO router.

[0110] In the present embodiment, the listening module ME is included in the monitoring device DI. It thus appears that the exchange of information between the router RO and the listening module is carried out using the communication module MCDI.

[0111] Each entity E1, E2, E3, En corresponds to a user as symbolized in figure 1 . Each user has a terminal T1, T2, T3, Tn arranged to exchange information in the communication network R1 and in the external communication network R2. Each terminal T1, T2, T3, Tn comprises a communication module and a human-machine interface. The information provided by the processing unit UT can in particular be displayed by this interface.

[0112] For example, this is a telephone capable of connecting to a Wi-Fi network corresponding to the R1 communications network and to a 3G network corresponding to the external R2 communications network.

[0113] As detailed below, it will appear that each terminal T1, T2, T3, Tn referenced is a terminal said to be “monitored” by the SY monitoring system.

[0114] Alternatively, the monitoring device may include a detection system having a plurality of AC motion detectors and a plurality of independent elements, each AC motion detector being provided in a corresponding independent element.

[0115] In this case the detection system comprises a central entity provided with a processor, the system being capable of generating an independent wired and / or wireless network so that the central entity can exchange information with each AC motion detector of the plurality of AC motion detectors.

[0116] This makes it possible to monitor intrusions in the entire building by detecting movements in each room. How to reference a family account

[0117] As illustrated in the figure 3 , a process for referencing a family account aims to reference each terminal T1, T2, T3, Tn of the family members.

[0118] The referencing process is carried out by the SY monitoring system with the aim that a referencing of the terminals T1, T2, T3, Tn of the family is carried out in memory of the UT processing unit.

[0119] A first step E1 consists of the creation and / or modification of a family account comprising at least one user profile via the interface of a terminal, for example terminal T1. Each terminal T1, T2, T3, Tn can have a user profile associated with it.

[0120] The user profiles associated with each terminal T1, T2, T3, Tn are stored in memory at the processing unit UT and / or the server SE. The input operations for creating and / or modifying a family account can be carried out using the interface of the terminal T1 which acts as a remote interface of the processing unit UT. This creation and / or modification step can for example be carried out using a software application installed on the terminal T1. A second step E2 consists of assigning a reference as administrator terminal Ta and / or receiver terminal Tr of at least one terminal T1, T3 corresponding to a user profile of a family account.

[0121] An administrator is able to send ICC command and / or control information to the UT processing unit and a receiver is able to receive IR return information from the UT processing unit.

[0122] In the example shown in the figure 1 , terminals T1 and T3 have been defined as administrator terminals Ta, in other words these are terminals T1, T3 qualified as “supervisors”. Terminal T2 is associated with a transmitter profile

[0123] At the end of these steps E1 and E2, it therefore appears that the terminals T1, T2, T3, Tn can be described as “monitored” and that the terminals T1 and T3 are “monitoring”.

[0124] A "monitoring" terminal capable of receiving IR return information but not configured to transmit ICC command and / or control information corresponds to a receiver profile. This terminal could therefore not modify the settings of the UT processing unit, unlike an administrator.

[0125] A third step E3 consists of the temporary establishment of a local communication network R3 for the connection of the monitoring device DI and / or the listening module ME to the communication network R1 and possibly the configuration of the terminal profiles.

[0126] As illustrated in the figure 4 , the monitoring device DI establishes the local communication network R3. In the presented embodiment the listening module ME is included in the monitoring device DI.

[0127] A fourth step E4 consists of the reception by the monitoring device DI and / or the listening module ME of an RF access reference to the communication network R1.

[0128] This step E4 is preceded by a step E04 consisting of scanning a pattern such as a barcode with the terminal T1, the pattern corresponding to an identification of the monitoring device DI and / or the listening module ME.

[0129] The identification of the monitoring device DI and / or the listening module ME by the terminal T1 equipped with a camera allows the transfer of this identification to the router RO and / or the processing unit UT which authorizes the connection by sending the RF access reference to the monitoring device DI and / or listening module ME in the communication network R1.

[0130] A step E5 following the reception step E4 consists of connecting the monitoring device DI to the communication network R1 using the RF access reference.

[0131] This referencing process therefore makes it possible to define which terminals are "monitored" and which are "monitoring" terminals and also to easily allow the connection of the DI monitoring device and / or the ME listening module to the R1 communication network.

[0132] Of course, after carrying out this referencing process, it is possible to modify the authorizations of the referenced terminals T1, T2, T3, Tn from an administrator terminal Ta. Attendance control process

[0133] As illustrated in the Figure 5 , a presence control method in a surveillance zone ZS is executed by a surveillance system SY to determine a risk of intrusion of a malicious person into the surveillance zone ZS.

[0134] The presence control method comprises a step EM1 of detecting an absence of movement or at least one movement in a detection zone ZD of the monitoring zone ZS. This step EM1 is carried out by the monitoring device DI using its motion detector CA.

[0135] The presence control method then comprises a step EM2 of creating and / or modifying movement information IM in memory of the monitoring device DI, this information being time-stamped by the monitoring device DI. The movement information IM indicates the absence of movement or one or more movements of entities E1, E2, E3, En detected.

[0136] A step EP1 consists of detecting the absence or presence of at least one terminal T1, T2, Tn in the communication network R1 as illustrated in figure 1 .

[0137] This detection is carried out by means of the router RO and consists of a search for the terminals T1, T2, Tn in at least one data packet exchanged within the communication network R1. The router RO provides a data packet exchanged within the communication network R1 to the listening module ME.

[0138] The communication network R1 is the network generated by the router RO and it is extended in the monitoring area ZS. It is for example a WiFi network, in particular a local and secure network.

[0139] A step EP2 then consists of the creation and / or modification of IP presence information in the memory of the listening module ME, the IP presence information relating to the absence or presence of at least one terminal T1, T2, Tn in the communication network R1.

[0140] The IP presence information is timestamped by the ME listening module and may further include an indication relating to the solicitation of a detected terminal, for example T1.

[0141] This is, for example, an indicator of activity or inactivity of the terminal T1 on the communication network R1, relating to the fact that the terminal T1 has been used recently and / or a movement indicator originating from a measurement of the terminal T1 attesting to the movement of the terminal T1 (for example, information originating from a location system (GPS) of the terminal T1).

[0142] The similarity between steps EM1, EM2 on the one hand and EP1, EP2 on the other hand then appears: the presence of an entity E1, E2, En is detected and the presence of a terminal T1, T2, T3 also.

[0143] The presence control method comprises a step EM3 consisting of sending the movement information IM by the monitoring device DI to the processing unit UT.

[0144] In the presented embodiment, the transmission of the IM movement information is carried out via the RO router. However, other communication links can be set up alternatively.

[0145] A step EP3 consists of sending the IP presence information by the listening module ME, that is to say in the embodiment presented by the monitoring device DI, to the processing unit UT.

[0146] As with the IM movement information, in the presented embodiment, the transmission of the IP presence information is carried out via the RO router. However, other communication links can be set up alternatively.

[0147] The motion detector CA is in quasi-permanent operation (in other words, periods of standby of the motion detector can alternate with periods in which it is active, but a movement is detected instantaneously on a human scale), that is to say that steps EM1 and EM2 are carried out in a quasi-continuous manner. Depending on the sequence of steps of the presence control method detailed above, several operating modes can be distinguished.

[0148] The detection step EP1 is carried out after an entity E2 has been detected during step EM1 in an operating mode called “alarm activated”.

[0149] Step EP3 of sending the IP presence information is in “alarm activated” mode carried out following step EP2 of creating and / or modifying the IP presence information, the sending step EM3 being carried out at the same time as step EP3.

[0150] In the "alarm activated" operating mode, it therefore appears that motion detection is permanent and that presence detection is carried out each time a movement is detected, the IM motion information and IP presence information then being transferred to the UT processing unit.

[0151] This operating mode is the fastest for sending IP presence information and IM movement information to the UT processing unit.

[0152] Alternatively, this sending step EP3 may be subject to the reception by the listening module ME of a corresponding request sent by the processing unit UT. Step EP3 may also be carried out according to a defined time base.

[0153] The choice of this setting depends on the need to have recent IP presence information for the UT processing unit and also depends on limiting the power consumption of the BA battery of the DI monitoring device.

[0154] According to an operating mode called “alarm deactivated”, the sending step EP3 is carried out according to a defined time base, the aim being to limit the energy consumption of the monitoring device DI. In this case, the sending step EM3 is carried out at the same time as the sending step EP3. This operating mode is not part of the invention.

[0155] It therefore appears according to this embodiment that the DI monitoring device collects a set of IM movement information and a set of IP presence information but sends this information according to the defined time base.

[0156] The EP1 detection step can also be carried out repeatedly at a determined frequency for reduced energy consumption in “alarm deactivated” operating mode.

[0157] A step ET1 then consists of the reception of the IP presence information and / or the IM movement information by the processing unit, via the router RO in the embodiment presented.

[0158] A step ET11 of recording in the memory of the processing unit UT the received IP and / or IM information can then be carried out. This arrangement makes it possible to create a history of the IP presence information and / or IM movement information because these are time-stamped.

[0159] A step ET2 of applying an association function to the presence information IP and / or the movement information IM is then carried out by the processing unit UT.

[0160] The purpose of applying the association function is to generate IC correspondence information relating to the correspondence or non-correspondence between a user profile previously referenced in connection with a T2 terminal and a T2 terminal whose presence is detected.

[0161] Thus, the association function makes it possible to determine whether a detected movement either corresponds or does not correspond to the presence of a previously referenced T2 terminal. It is therefore possible to detect any movement that does not correspond to a movement of a user having their referenced terminal with them.

[0162] A step ET3 then consists of the analysis of the correspondence information IC by the processing unit UT in order to obtain a result relating to a potential intrusion into the surveillance zone ZS.

[0163] The analysis is carried out according to an irregularity determination criterion, the aim of which is to trigger an alarm and / or warn a receiving terminal Tr of the irregularity.

[0164] The criterion for determining irregularity may correspond to a detected movement not linked to a user profile, i.e. a potential intrusion.

[0165] It may also be the detection of a known terminal without corresponding movement for a specific period of time. In this case, the irregularity may correspond to discomfort of the user of the terminal in question or an inability to leave the ZS surveillance zone.

[0166] Step ET2 of applying the association function and step ET3 of analyzing the correspondence information IC can be carried out several times, the movement information IM and / or the presence information IP previously recorded in the memory of the processing unit UT during step ET11 then being taken into account.

[0167] It therefore appears that the UT processing unit makes it possible to gather IP presence information and IM movement information at the UT processing unit level to determine any potential intrusion or irregularity within the ZS surveillance zone.

[0168] Step ECC1 consists of the processing unit UT sending return information IR to a receiver terminal Tr or administrator terminal Ta. This sending can be carried out via the router RO when the receiver terminal Tr or administrator terminal Ta is connected to the communication network R1 or via the external communication network R2 when the receiver terminal Tr or administrator terminal Ta is outside the monitoring zone ZS.

[0169] The IR return information includes an indication relating to the IM movement information and / or the IP presence information and / or a result of the analysis of the IC correspondence information.

[0170] The terminal Tr therefore carries out a reception step ER1, ER2 of this IR return information as illustrated in Figure 5 .

[0171] Similarly, an administrator terminal Ta is able to generate command and / or control information ICC and send it to the processing unit UT during a step EC1.

[0172] An ECC2 step of receiving the command and / or control information is then carried out by the processing unit UT either via the router RO when the administrator terminal Ta is connected to the communication network R1 or via the external communication network R2.

[0173] ICC command and / or control information may include: a request relating to the execution of a step EM1 of detecting an absence of movement or at least one movement of at least one entity E1, E2, En and / or a step EP1 of detecting an absence and / or a presence of at least one terminal T1, T2, T3, Tn in a communication network R1, and / or, a request relating to the execution of a step ET2 of applying the association function and / or to the execution of a step ET3 of analyzing the correspondence information IC, and / or, a request relating to the execution of a step ECC1 of sending by the processing unit UT of return information IR.

[0174] It therefore appears that the UT processing unit of the SY surveillance system centralizes IP presence information and IM movement information to deduce irregularities and warn receivers and / or administrators.

[0175] It goes without saying that the invention is not limited to the single embodiment described above as an example; on the contrary, it encompasses all the variant embodiments included in the subject of the appended claims.
